`ABSTRACT
`( 57 )
`Systems , apparatuses , and methods are described for wire
`less communications . A base station may send , to a wireless
`device , one or more radio resource control messages com
`prising parameters for one or more bandwidth parts or other
`wireless resources . The base station may send , to the wire
`less device , downlink control information comprising one or
`more bandwidth part identifiers . The wireless device may
`switch , based on the downlink control information , from a
`first bandwidth part to a second bandwidth part .

`RESOURCES
`CROSS - REFERENCE TO RELATED
`APPLICATIONS
`[ 0001 ] This application claims the benefit of U . S . Provi
`sional Application No . 62 / 577 , 995 , titled “ Group Common
`DCI ” and filed on Oct . 27 , 2017 , the disclosure of which is
`hereby incorporated by reference in its entirety .
`BACKGROUND
`In wireless communications , bandwidth parts and
`[ 0002 ]
`other wireless resources may be used by wireless devices . A
`base station may determine that one or more wireless
`devices should use or switch to one or more bandwidth parts
`or other wireless resources . It is desired to improve wireless
`communications without adversely increasing signaling
`overhead and / or decreasing spectral efficiency .
`SUMMARY
`[ 0003 ] The following summary presents a simplified sum
`mary of certain features . The summary is not an extensive
`overview and is not intended to identify key or critical
`elements .
`[ 0004 ] Systems , apparatuses , and methods are described
`for communications associated with switching bandwidth
`parts or other wireless resources . A base station may send , to
`a wireless device , one or more radio resource control mes
`sages comprising parameters for one or more bandwidth
`parts and / or an index or an identifier associated with the
`wireless device . The base station may send , to the wireless
`device , downlink control information comprising one or
`more bandwidth part identifiers . The wireless device may
`determine , based on the index or the identifier for the
`wireless device , a position of a bandwidth part identifier in
`the downlink control information . The wireless device may
`switch from a first bandwidth part to a second bandwidth
`part indicated by the bandwidth part identifier .

`[ 0141 ] Examples may be implemented using various
`physical layer modulation and transmission mechanisms .
`Example transmission mechanisms may include , but are not
`limited to : CDMA , OFDM , TDMA , Wavelet technologies ,
`and / or the like . Hybrid transmission mechanisms such as
`TDMA / CDMA , and OFDM / CDMA may also be employed .
`Various modulation schemes may be used for signal trans
`mission in the physical layer . Examples of modulation
`schemes include , but are not limited to : phase , amplitude ,
`code , a combination of these , and / or the like . An example
`radio transmission method may implement QAM using
`BPSK , QPSK , 16 - QAM , 64 - QAM , 256 - QAM , and / or the
`like . Physical radio transmission may be enhanced by
`dynamically or semi - dynamically changing the modulation
`and coding scheme depending on transmission requirements
`and radio conditions .
`[ 0142 ] FIG . 1 shows example sets of OFDM subcarriers .
`As shown in this example , arrow ( s ) in the diagram may
`depict a subcarrier in a multicarrier OFDM system . The
`OFDM system may use technology such as OFDM tech
`nology , DFTS - OFDM , SC - OFDM technology , or the like .
`For example , arrow 101 shows a subcarrier transmitting
`information symbols . FIG . 1 is shown as an example , and a
`typical multicarrier OFDM system may include more sub
`carriers in a carrier . For example , the number of subcarriers
`in a carrier may be in the range of 10 to 10 , 000 subcarriers .
`FIG . 1 shows two guard bands 106 and 107 in a transmission
`band . As shown in FIG . 1 , guard band 106 is between
`subcarriers 103 and subcarriers 104 . The example set of

`
`subcarriers A 102 includes subcarriers 103 and subcarriers
`104 . FIG . 1 also shows an example set of subcarriers B 105 .
`As shown , there is no guard band between any two subcar
`riers in the example set of subcarriers B 105 . Carriers in a
`multicarrier OFDM communication system may be contigu
`ous carriers , non - contiguous carriers , or a combination of
`both contiguous and non - contiguous carriers .
`[ 0143 ]
`FIG . 2 shows an example timing arrangement with
`transmission time and reception time for two carriers . A
`multicarrier OFDM communication system may include one
`or more carriers , for example , ranging from 1 to 10 carriers .
`Carrier A 204 and carrier B 205 may have the same or
`different timing structures . Although FIG . 2 shows two
`synchronized carriers , carrier A 204 and carrier B 205 may
`or may not be synchronized with each other . Different radio
`frame structures may be supported for FDD and TDD duplex
`mechanisms . FIG . 2 shows an example FDD frame timing .
`Downlink and uplink transmissions may be organized into
`radio frames 201 . In this example , radio frame duration is 10
`milliseconds ( msec ) . Other frame durations , for example , in
`the range of 1 to 100 msec may also be supported . In this
`example , each 10 msec radio frame 201 may be divided into
`ten equally sized subframes 202 . Other subframe durations
`such as including 0 . 5 msec , 1 msec , 2 msec , and 5 msec may
`also be supported . Subframe ( s ) may consist of two or more
`slots ( e . g . , slots 206 and 207 ) . For the example of FDD , 10
`subframes may be available for downlink transmission and
`10 subframes may be available for uplink transmissions in
`each 10 msec interval . Uplink and downlink transmissions
`may be separated in the frequency domain . A slot may be 7
`or 14 OFDM symbols for the same subcarrier spacing of up
`to 60 kHz with normal CP . A slot may be 14 OFDM symbols
`for the same subcarrier spacing higher than 60 kHz with
`normal CP . A slot may include all downlink , all uplink , or a
`downlink part and an uplink part , and / or alike . Slot aggre
`gation may be supported , for example , data transmission
`may be scheduled to span one or multiple slots . For example ,
`a mini - slot may start at an OFDM symbol in a subframe . A
`mini - slot may have a duration of one or more OFDM
`symbols . Slot ( s ) may include a plurality of OFDM symbols
`203 . The number of OFDM symbols 203 in a slot 206 may
`depend on the cyclic prefix length and subcarrier spacing .
`[ 0144 ] FIG . 3 shows an example of OFDM radio
`resources . The resource grid structure in time 304 and
`frequency 305 is shown in FIG . 3 . The quantity of downlink
`subcarriers or RBs may depend , at least in part , on the
`downlink transmission bandwidth 306 configured in the cell .
`The smallest radio resource unit may be called a resource
`element ( e . g . , 301 ) . Resource elements may be grouped into
`resource blocks ( e . g . , 302 ) . Resource blocks may be grouped
`into larger radio resources called Resource Block Groups
`( RBG ) ( e . g . , 303 ) . The transmitted signal in slot 206 may be
`described by one or several resource grids of a plurality of
`subcarriers and a plurality of OFDM symbols . Resource
`blocks may be used to describe the mapping of certain
`physical channels to resource elements . Other pre - defined
`groupings of physical resource elements may be imple
`mented in the system depending on the radio technology . For
`example , 24 subcarriers may be grouped as a radio block for
`a duration of 5 msec . A resource block may correspond to
`one slot in the time domain and 180 kHz in the frequency
`domain ( for 15 kHz subcarrier bandwidth and 12 subcarri
`ers ) .
`
`[ 0145 ] Multiple numerologies may be supported . A
`numerology may be derived by scaling a basic subcarrier
`spacing by an integer N . Scalable numerology may allow at
`least from 15 kHz to 480 kHz subcarrier spacing . The
`numerology with 15 kHz and scaled numerology with
`different subcarrier spacing with the same CP overhead may
`align at a symbol boundary every 1 msec in a NR carrier .

`FIG . 4 shows hardware elements of a base station
`401 and a wireless device 406 . A communication network
`400 may include at least one base station 401 and at least one
`wireless device 406 . The base station 401 may include at
`least one communication interface 402 , one or more pro
`cessors 403 , and at least one set of program code instructions
`405 stored in non - transitory memory 404 and executable by
`the one or more processors 403 . The wireless device 406
`may include at least one communication interface 407 , one
`or more processors 408 , and at least one set of program code
`instructions 410 stored in non - transitory memory 409 and
`executable by the one or more processors 408 . A commu
