`
`Systems, methods, and instrumentalities are disclosed for
`downlink resource allocation associated with a shared fre(cid:173)
`quency band. A WTRU may receive resource allocation infor(cid:173)
`mation associated with a component carrier and at least one
`carrier segment. The component carrier and the least one
`carrier segment may each comprise a plurality of resource
`block groups (RBG). At least two bitmaps may be associated
`with the resource allocation information. A size of a resource
`block group (RBG) of the component carrier and the at least
`one carrier segment may be based on a combined number of
`resource blocks (RB) of the component carrier and the one or
`more carrier segments divided by a 3GPP Rel-8/Rel-10 RBG
`size of the component carrier. The WTRU may determine at
`least one RBG allocated to the WTRU using the resource
`allocation information and may receive and decode the at
`least one RBG allocated to the WTRU.

`
`This application claims the benefit of U.S. Provisional
`Patent Application No. 61/522,883, filed Aug. 12, 2011, U.S.
`Provisional Patent Application No. 61/555,887, filed Nov. 4,
`2011, and U.S. Provisional Patent Application No. 61/611,
`244, filed Mar. 15, 2012, the contents of which are hereby
`incorporated by reference herein.
`
`BACKGROUND
`
`2
`carrier segment such that the number of null RBs plus the
`number ofRBs of the second carrier segment is divisible by
`the size of the RBGs. The number of null RBs may be vari(cid:173)
`able.
`The resource allocation information may comprise three
`bitmaps. A first bitmap may be associated with the RBGs of a
`component carrier. A second bitmap may be associated with
`the RBGs of a first carrier segment. A third bitmap may be
`associated with the RBGs of a second carrier segment. A
`10 number ofbits/RBG for the first bitmap, the second bitmap,
`and the third bitmap may be the number of resource blocks
`(RB) in the respective carrier divided by the size of the RBG.
`If the number of RBGs of the component carrier, the first
`15 carrier segment, and/or the second carrier segment is not an
`integer multiple of the size of the RBGs, then a number of null
`RBs may be inserted into the last RBG of the respective
`carrier such that the number of null RBs plus the number of
`RBs of the respective carrier is divisible by the size of the
`20 RBGs.
`A WTRU may receive resource allocation information
`associated with a component carrier and at least one carrier
`segment. The component carrier and the least one carrier
`segment comprising a plurality of resource block groups
`(RBG). A size of a resource block group (RBG) of the com(cid:173)
`ponent carrier and the at least one carrier segment may be
`based on a scaling factor multiplied by a 3GPP Rel-10 RBG
`size of the component carrier. The 3GPP Rel-10 RBG size
`may be determined by the system bandwidth of the compo(cid:173)
`nent carrier. The WTRU may determine at least one RBG
`allocated to the WTRU using the resource allocation infor-
`mation. The WTRU may receive and decode the at least one
`RBG allocated to the WTRU.
`The scaling factor may be determined by the maximum
`number of resource blocks (RB) of the component carrier and
`the one or more carrier segments. If a combined number of
`RBs of the one or more carrier segments is less than or equal
`to the number of RBs of the component carrier, then the
`scaling factor may be two. If a combined number of RBs of
`40 the one or more carrier segments is greater than the number of
`RBs of the component carrier, then the scaling factor may be
`x, wherein x equals a combined number of RBs of the com(cid:173)
`ponent carrier and the one or more carrier segments divided
`by a number of RBs of the component carrier.
`The resource allocation information may be associated
`with a bitmap. A number of bits for the bitmap may be
`determined by a combined number ofRBs of the component
`carrier and the one or more carrier segments divided by the
`size of a RBG. Two or more consecutive RBs may be grouped
`50 together into a RBG element according to the size of the
`RBG. A RB may be grouped together with one or more
`nonconsecutive RB into a RBG element according to the size
`of the RBG.
`A WTRU may receive resource allocation information
`55 associated with a component carrier and at least one carrier
`segment. The component carrier and the least one carrier
`segment may comprise a plurality of resource block groups
`(RBG). A size of a RBG of the component carrier and the at
`least one carrier segment may be based on a combined num-
`60 ber of resource blocks (RB) of the component carrier and the
`one or more carrier segments divided by a 3GPP Rel-10 RBG
`size of the component carrier. The 3GPP Rel-10 RBG size
`may be determined by the system bandwidth of the compo(cid:173)
`nent carrier. The WTRU may determine at least one RBG
`65 allocated to the WTRU using the resource allocation infor(cid:173)
`mation. The WTRU may receive and decode the at least one
`RBG allocated to the WTRU.
`
`The Third Generation Partnership Project (3GPP) Long
`Term Evolution (LTE) standards provide specifications for
`high performance air interfaces for cellular mobile commu(cid:173)
`nication systems. LTE specifications are based on Global
`System for Mobile Communications (GSM) specifications
`and provide the upgrade path for 3G networks to evolve into
`partially-compliant 4G networks. LTE Advanced is an
`enhancement of the LTE standard that provides a fully-com(cid:173)
`pliant 4G upgrade path for LTE and 3G networks.
`A goal of 3GPPP and LTE is the simplification of the 25
`architecture of cellular mobile communication systems. One
`step in simplifying this architecture is transitioning from
`existing 3GPP universal mobile telecommunications system
`(UMTS) combined circuit and packet switched networks to
`pure internet protocol (IP) packet switched systems. Because 30
`the adoption of LTE is an ongoing process and many mobile
`devices are not yet compatible with LTE packet switched
`technologies, operators of LTE networks will typically run
`such networks in conjunction with circuit-switched net(cid:173)
`works. This allows network operators to service users of 35
`circuit-switched compatible devices as well as users ofLTE
`compatible devices.
`
`SUMMARY
`
`Systems, methods, and instrumentalities are disclosed for
`downlink resource allocation associated with a shared fre(cid:173)
`quency band. A WTRU may receive resource allocation infor(cid:173)
`mation associated with a component carrier and at least one
`carrier segment. The component carrier and the least one 45
`carrier segment may each comprise a plurality of resource
`block groups (RBG). A size of a resource block group (RBG)
`of the component carrier and a RBG of the at least one carrier
`segment may be determined by a function ofbandwidth of the
`component carrier. At least two bitmaps may be associated
`with the resource allocation information. The WTRU may
`determine at least one RBG allocated to the WTRU using the
`resource allocation information. The WTRU may receive and
`decode the at least one RBG allocated to the WTRU.
`The resource allocation information may comprise two
`bitmaps. A first bitmap may be associated with the RBGs of
`the component carrier and the RBGs of a first carrier segment.
`A second bitmap may be associated with the RBGs of a
`second carrier segment. A number of bits/RBG for the first
`bitmap may be equal to a combined number of resource
`blocks (RB) in the component carrier and first carrier segment
`divided by the size of the RBG. A number ofbits/RBG for the
`second bitmap may be equal to a number of resource blocks
`(RB) in the second carrier segment divided by the size of the
`RBG. If a number of RBGs of the second carrier segment is
`not an integer multiple of the size of the RBGs, then a number
`of null RBs may be inserted into a last RBG of the second

`
`DETAILED DESCRIPTION
`
`A detailed description of illustrative embodiments will
`now be described with reference to the various Figures.
`Although this description provides a detailed example of
`possible implementations, it should be noted that the details 45
`are intended to be exemplary and in no way limit the scope of
`the application.
`FIG. lA is a diagram of an example communications sys(cid:173)
`tem 100 in which one or more disclosed embodiments may be
`implemented. The communications system 100 may be a 50
`multiple access system that provides content, such as voice,
`data, video, messaging, broadcast, etc., to multiple wireless
`users. The communications system 100 may enable multiple
`wireless users to access such content through the sharing of
`system resources,
`including wireless bandwidth. For 55
`example, the communications systems 100 may employ one
`or more channel access methods, such as code division mul(cid:173)
`tiple access
`(CDMA),
`time division multiple access
`(TDMA), frequency division multiple access (FDMA),
`orthogonal FDMA (OFDMA), single-carrier FDMA (SC- 60
`FDMA), and the like.
`As shown in FIG. lA, the communications system 100 may
`include wireless transmit/receive units (WTRU s) 102a, 102b,
`102c, and/or 102d (which generally or collectively may be
`referred to as WTRU 102), a radio access network (RAN) 65
`103/104/105, a core network 106/107 /109, a public switched
`telephone network (PSTN) 108, the Internet 110, and other
`
`4
`networks 112, though it will be appreciated that the disclosed
`embodiments contemplate any number ofWTRUs, base sta(cid:173)
`tions, networks, and/or network elements. Each of the
`WTRUs 102a, 102b, 102c, 102d may be any type of device
`5 configured to operate and/or communicate in a wireless envi(cid:173)
`ronment. By way of example, the WTRUs 102a, 102b, 102c,
`102d may be configured to transmit and/or receive wireless
`signals and may include user equipment (UE), a mobile sta(cid:173)
`tion, a fixed or mobile subscriber unit, a pager, a cellular
`10 telephone, a personal digital assistant (PDA), a smartphone, a
`laptop, a netbook, a personal computer, a wireless sensor,
`consumer electronics, and the like.
`The communications systems 100 may also include a base
`station 114a and a base station 114b. Each of the base stations
`15 114a, 114b may be any type of device configured to wire(cid:173)
`lessly interface with at least one of the WTRUs 102a, 102b,
`102c, 102d to facilitate access to one or more communication
`networks, such as the core network 106/107 /109, the Internet
`110, and/or the networks 112. By way of example, the base
`20 stations 114a, 114b may be a base transceiver station (BTS),
`a Node-B, an eNode B, a Home Node B, a Home eNode B, a
`site controller, an access point (AP), a wireless router, and the
`like. While the base stations 114a, 114b are each depicted as
`a single element, it will be appreciated that the base stations
`25 114a, 114b may include any number of interconnected base
`stations and/or network elements.
`The base station 114a may be part of the RAN 103/104/
`105, which may also include other base stations and/or net(cid:173)
`work elements (not shown), such as a base station controller
`30 (BSC), a radio network controller (RNC), relay nodes, etc.
`The base station 114a and/or the base station 114b may be
`configured to transmit and/or receive wireless signals within
`a particular geographic region, which may be referred to as a
`cell (not shown). The cell may further be divided into cell
`35 sectors. For example, the cell associated with the base station
`114a may be divided into three sectors. Thus, in one embodi(cid:173)
`ment, the base station 114a may include three transceivers,
`i.e., one for each sector of the cell. In another embodiment, the
`base station 114a may employ multiple-input multiple output
`40 (MIMO) technology and, therefore, may utilize multiple
`transceivers for each sector of the cell.
`The base stations 114a, 114b may communicate with one
`or more of the WTRUs 102a, 102b, 102c, 102d over an air
`interface 115/116/117, which may be any suitable wireless
`communication link ( e.g., radio frequency (RF), microwave,
`infrared (IR), ultraviolet (UV), visible light, etc.). The air
`interface 115/116/117 may be established using any suitable
`radio access technology (RAT).
`More specifically, as noted above, the communications
`system 100 may be a multiple access system and may employ
`one or more channel access schemes, such as CDMA,
`TDMA, FDMA, OFDMA, SC-FDMA, and the like. For
`example, the base station 114a in the RAN 103/104/105 and
`the WTRUs 102a, 102b, 102c may implement a radio tech(cid:173)
`nology such as Universal Mobile Telecommunications Sys(cid:173)
`tem (UMTS) Terrestrial Radio Access (UTRA), which may
`establish the air interface 115/116/117 using wideband
`CDMA (WCDMA). WCDMA may include communication
`protocols such as High-Speed Packet Access (HSPA) and/or
`Evolved HSPA (HSPA+ ). HSPA may include High-Speed
`Downlink Packet Access (HSDPA) and/or High-Speed
`Uplink Packet Access (HSUPA).
`In another embodiment, the base station 114a and the
`WTRU s 102a, 102b, 102c may implement a radio technology
`such as Evolved UMTS Terrestrial Radio Access (E-UTRA),
`which may establish the air interface 115/116/117 using Long
`Term Evolution (LTE) and/or LTE-Advanced (LTE-A).

`In other embodiments, the base station 114a and the
`WTRU s 102a, 102b, 102c may implement radio technologies
`such as IEEE 802.16 (i.e., Worldwide Interoperability for
`Microwave Access (WiMAX)), CDMA2000, CDMA2000
`IX, CDMA2000 EV-DO, Interim Standard 2000 (IS-2000), 5
`Interim Standard 95 (IS-95), Interim Standard 856 (IS-856),
`Global System
`for Mobile communications
`(GSM),
`Enhanced Data rates for GSM Evolution (EDGE), GSM
`EDGE (GERAN), and the like.
`The base station 114b in FIG. lA may be a wireless router, 10
`Home Node B, Home eNode B, or access point, for example,
`and may utilize any suitable RAT for facilitating wireless
`connectivity in a localized area, such as a place of business, a
`home, a vehicle, a campus, and the like. In one embodiment,
`the base station 114b and the WTRUs 102c, 102d may imple- 15
`ment a radio technology such as IEEE 802.11 to establish a
`wireless local area network (WLAN). In another embodi(cid:173)
`ment, the base station 114b and the WTRU s 102c, 102d may
`implement a radio technology such as IEEE 802.15 to estab(cid:173)
`lish a wireless personal area network (WPAN). In yet another 20
`embodiment, the base station 114b and the WTRUs 102c,
`102d may utilize a cellular-based RAT (e.g., WCDMA,
`CDMA2000, GSM, LTE, LTE-A, etc.) to establish a picocell
`or femtocell. As shown in FIG. lA, the base station 114b may
`have a direct connection to the Internet 110. Thus, the base 25
`station 114b may not be required to access the Internet 110 via
`the core network 106/107/109.
`The RAN 103/104/105 may be in communication with the
`core network 106/107/109, which may be any type of net(cid:173)
`work configured to provide voice, data, applications, and/or
`voice over internet protocol (VoIP) services to one or more of
`the WTRUs 102a, 102b, 102c, 102d. For example, the core
`network 106/107/109 m
