Abstract: A base station and user equipment (UE) may determine, based on a synchronization signal block (SSB) burst and an offset, an index slot, of a system frame number (SFN), corresponding to a Type0-PDCCH common search space (CSS). The base station may transmit, and the UE may receive, a PDCCH signal that includes the Type0-PDCCH CSS, such that the UE may monitor the Type0-PDCCH CSS from the base station. The offset (Ou) may be hardcoded as one of values 0, 2.5, 5, or 7.5, and one offset value may be used for one, more than one, or all SCS numerologies. The offset may be modified by a delta (Δ) value, a scaling factor, and/or a combination thereof.

Abstract: Techniques described herein may enable base stations and user equipment (UEs) to implement initial access related signaling that may vary the number of synchronization signal blocks (SSBs) transmitted by a base station to better ensure that control frame transmissions (e.g., 120 kilohertz (kHz) subcarrier spacing (SCS) transmissions) are not overly encumbered by SSBs. A base station may indicate whether a discovery burst transmission window (DBTW) is enabled or disabled, whether listen-before-talk (LBT) is enabled or disabled, and whether transmissions correspond to a licensed band, unlicensed band, or combination thereof. The base station may also indicate a number of candidate SSBs per DBTW and/or which SSBs/SSB groups are active (e.g., actually transmitted) per discovery burst (DB).

Abstract: A method is to provide traffic related information in lower layers for an XR system and associated apparatuses. In one aspect, a user equipment (UE) is configured to receive traffic related information from a peer UE or an application server. The UE then transmits the traffic related information to a base station (BS) using a radio resource control (RRC) message such as UEAssistanceInformation as provided by 3GPP technical specifications, a medium access control (MAC) control element (CE), or a physical uplink control channel (PUCCH). The transmission of the traffic related information from the UE enhances the wireless communication service for the XR system.

Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to configure a hand over (HO) or a primary secondary cell (PSCell) addition based on a channel state information reference signal (CSI-RS) based contention free random access (CFRA) procedure. A CSI-RS rough timing of a CSI-RS position can be determined based on a synchronization signal block (SSB) associated with a CSI-RS or a serving cell timing. A CFRA transmit timing can be determined based on the CSI-RS rough timing or a CSI-RS fine timing that is derived from a timing and frequency (T/F) tracking operation on the CSI-RS. Reference signal receive power (RSRP) measurement(s) can be made on the CSI-RS for performing the CSI-RS based CFRA procedure with transmissions according to the CSI-RS transmit timing of the CSI-RS that satisfies an RSRP threshold.

Abstract: This disclosure relates to techniques for performing partial frequency domain transmissions in a wireless communication system. A wireless device and a cellular base station may establish a wireless link. The wireless device may receive an uplink grant from the cellular base station. The uplink grant may provide a set of time domain resources and a set of frequency domain resources on which to perform an uplink transmission. The wireless device may select a subset of frequency domain resources from the set of frequency domain resources and perform the uplink transmission using the selected resources.

Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP). Other approaches include setting the fixed frame period length to different sizes for each UE, using a random number of skipped fixed frame periods, and the gNB configuring UEs with multiple semi-static channel access mode parameters.

Abstract: A service device (e.g., a user equipment (UE), a new radio NR (gNB), or other network component) as a service provider/consumer can process or generate sidelink communications based on a downlink control information (DCI) for one or more sidelink configured grants that enables resource allocation for the sidelink communication. The device can determine whether to activate, release/deactivate, or request a retransmission for the one or more sidelink configured grants based on one or more fields of a DCI format 3_0 configuration of the DCI.

Abstract: To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method indicates a frequency resource reservation in sidelink control information (SCI). The method includes identifying a transport block (TB) for transmission to a UE; determining a total number of sub-channels (NSL) in a resource pool for sidelink communication, a number of sub-channels (Lsub) of the TB, a first starting sub-channel index x1 of a first retransmission of the TB, and a second starting sub-channel index x2 of a second retransmission of the TB. The method includes determining a frequency resource indication value (FRIV) based on NSL, LSUB, x1, and x2, wherein the FRIV represents a result of a predetermined function of Lsub, x1, and x2 that generates a unique value for possible combinations of Lsub, x1, and x2. The FRIV is encoded in SCI and the SCI is transmitted to the UE.
