`ABSTRACT
`( 57 )
`Systems , procedures , and instrumentalities are disclosed for
`distributed control in wireless systems , such as 5G flexible
`radio access technology ( RAT ) ( 5gFLEX ) . Example proce
`dures are provided for WTRU and network operation asso
`ciated with a distributed control plane architecture , connec
`tionless data transfer and dedicated system information
`acquisition . Distributed control may be provided , for
`example , by replicating a plurality of access control func
`tions ( ACFs ) using a plurality of instances in a plurality of
`different transmission / reception points ( TRPs ) with multi
`connectivity . The plurality of TRPs may concurrently pro
`vide control services to a WTRU . Centralized control func
`tions may manage core network connectivity and / or a
`plurality of user plane instances for the WTRU and / or may
`facilitate coordination between the plurality of ACF
`instances for the WTRU in the plurality of different TRPs of
`the WTRU ' s configuration .

`
`DETAILED DESCRIPTION
`A detailed description of illustrative embodiments
`[ 0023 ]
`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
`are intended to be examples and in no way limit the scope
`of the application .
`[ 0024 ]
`FIG . 1A is a diagram of an example communica
`tions system 100 in which one or more disclosed embodi
`ments may be implemented . The communications system
`100 may be a 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 example , the communications system 100
`may employ one or more channel access methods , such as
`code division multiple access ( CDMA ) , time division mul
`tiple access ( TDMA ) , frequency division multiple access
`( FDMA ) , orthogonal FDMA ( OFDMA ) , single - carrier
`FDMA ( SC - FDMA ) , and the like .
`[ 0025 ] As shown in FIG . 1A , the communications system
`100 may include wireless transmit / receive units ( WTRUS ) ,
`e . g . , WTRUS , 102a , 102b , 102c , and / or 102d ( which gen
`erally or collectively may be referred to as WTRU 102 ) , a
`radio access network ( RAN ) 103 / 104 / 105 , a core network
`106 / 107 / 109 , a public switched telephone network ( PSTN )
`108 , the Internet 110 , and other networks 112 , though it will
`be appreciated that the disclosed embodiments contemplate
`any number of WTRUs , base stations , networks , and / or
`network elements . Each of the WTRUS 102a , 102b , 102c ,
`102d may be any type of device configured to operate and / or
`communicate in
`a wireless environment . 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 station , a fixed
`or mobile subscriber unit , a pager , a cellular telephone , a
`personal digital assistant ( PDA ) , a smartphone , a laptop , a
`netbook , a personal computer , a wireless sensor , consumer
`electronics , and the like .
`( 0026 ]
`The communications system 100 may also include
`a base station 114a and a base station 114b . Each of the base
`stations 114a , 114b may be any type of device configured to
`wirelessly interface with at least one of the WTRUS 102a ,
`102b , 102c , 102d to facilitate access to one or more com
`munication networks , such as the core network 106 / 107 / 109 ,
`the Internet 110 , and / or the networks 112 . By way of
`example , the base 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 114a , 114b may include
`any number of interconnected base stations and / or network
`elements .
`[ 0027 ]
`The base station 114a may be part of the RAN
`103 / 104 / 105 , which may also include other base stations
`and / or network elements ( not shown ) , such as a base station
`controller ( 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

`

`

`US 2019 / 0174554 A1
`

`
`with the base station 114a may be divided into three sectors .
`Thus , in some embodiments , the base station 114a may
`include three transceivers , e . g . , one for each sector of the
`cell . In another embodiment , the base station 114a may
`employ multiple - input multiple output ( MIMO ) technology
`and , therefore , may utilize multiple transceivers for each
`sector of the cell .
`[ 0028 ] The base stations 114a . 114b may communicate
`with one or more of the WTRUS 102a , 1021 , 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 ) .
`[ 0029 ] More specifically , as noted above , the communi
`cations 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
`technology such as Universal Mobile Telecommunications
`System ( 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 ) .
`[ 0030 ]
`In another embodiment , the base station 114a and
`the WTRUS 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 - Ad
`vanced ( LTE - A ) .
`[ 0031 ]
`In other embodiments , the base station 114a and
`the WTRUS 102a , 102b , 102c may implement radio tech
`nologies such as IEEE 802 . 16 ( e . g . , Worldwide Interoper
`ability for Microwave Access ( WiMAX ) ) , CDMA2000 ,
`CDMA2000 IX , CDMA2000 EV - DO , Interim Standard
`2000 ( IS - 2000 ) , Interim Standard 95 ( IS - 95 ) , Interim Stan
`dard 856 ( IS - 856 ) , Global System for Mobile communica
`tions ( GSM ) , Enhanced Data rates for GSM Evolution
`( EDGE ) , GSM EDGE ( GERAN ) , and the like .
`[ 0032 ] The base station 114b in FIG . 1A may be a wireless
`router , 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 some
`embodiments , the base station 114b and the WTRUS 102c ,
`102d may implement a radio technology such as IEEE
`802 . 11 to establish a wireless local area network ( WLAN ) .
`In another embodiment , the base station 114b and the
`WTRUS 102c , 102d may implement a radio technology such
`as IEEE 802 . 15 to establish a wireless personal area network
`( WPAN ) . In yet another 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 . 1A , the
`base station 114b may have a direct connection to the
`Internet 110 . Thus , the base station 114b may not be required
`to access the Internet 110 via the core network 106 / 107 / 109 .
`[ 0033 ] The RAN 103 / 104 / 105 may be in communication
`with the core network 106 / 107 / 109 , which may be any type
`of network 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 may provide call control ,
`billing services , mobile location - based services , pre - paid
`calling , Internet connectivity , video distribution , etc . , and / or
`perform high - level security functions , such as user authen
`tication . Although not shown in FIG . 1A , it will be appre
`ciated that the RAN 103 / 104 / 105 and / or the core network
`106 / 107 / 109 may be in direct or indirect communication
`with other RANs that employ the same RAT as the RAN
`103 / 104 / 105 or a different RAT . For example , in addition to
`being connected to the RAN 103 / 104 / 105 , which may be
`utilizing an E - UTRA radio technology , the core network
`106 / 107 / 109 may also be in communication with another
`RAN ( not shown ) employing a GSM radio technology .
`[ 0034 ] The core network 106 / 107 / 109 may also serve as a
`gateway for the WTRUS 102a , 102b , 102c , 102d to access
`the PSTN 108 , the Internet 110 , and / or other networks 112 .
`The PSTN 108 may include circuit - switched telephone
`networks that provide plain old telephone service ( POTS ) .
`The Internet 110 may include a global system of intercon
`nected computer networks and devices that use common
`communication protocols , such as the transmission control
`protocol ( TCP ) , user datagram protocol ( UDP ) and the
`internet protocol ( IP ) in the TCP / IP internet protocol suite .
`The networks 112 may include wired or wireless commu
`nications networks owned and / or operated by other service
`providers . For example , the networks 112 may include
`another core network connected to one or more RANS ,
`which may employ the same RAT as
