Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

Abstract: Systems and methods of a wireless communications system using signals not traditionally used for positioning purposes for positioning measurements in both uplink (UL) and downlink (DL) are described herein. A user equipment (UE) may generate a UE capability information message indicating one or more signal types that the LE can process for DL positioning measurements and/or that the UE can send for UL positioning measurements. The one or more signal types so indicated may include signals not traditionally used for positioning measurements. The UE may send, to the base station, the UE capability information message. The wireless communications system may then configure the base station and/or the UE to use such signal types with one or more positioning methods. In some embodiments, the base station may also indicate to the UE a subset of signals of an indicated type which should be processed for DL measurements/sent for UL measurements.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a Discontinuous Reception (DRX) switching command from a network device and switches, based on the DRX switching command, from a current first Connected Mode DRX (cDRX) configuration to a different second cDRX configuration. Each of the first cDRX configuration and the second cDRX configuration is a configuration selected from a group consisting of: a default cDRX configuration; and at least one non-default cDRX configuration. Each non-default cDRX configuration of the at least one non-default cDRX configuration comprises a cDRX periodicity and a cDRX offset corresponding to a periodicity and an offset of a Semi-Persistent Scheduling (SPS) or Configured Grant (CG) configuration, respectively.

Abstract: Apparatuses, systems, and methods for a wakeup radio in a wireless communication system, e.g., in 5G NR systems and beyond. An RRC state is introduced to support a wakeup radio/, including defining transition mechanisms to/from existing RRC states. Further, signaling is introduced to activate a wakeup radio/activate an RRC low power state. Additionally, a bandwidth part framework for a wakeup signal is defined in which a base station may configure one or more time/frequency resources or a wakeup signal for a wakeup radio. In addition, various mechanisms are introduced to switch a wakeup radio on as well as to switch a wakeup radio off. Also, mechanisms are introduced for multiplexing multiple wakeup signals in a time/frequency resource, configuring a wakeup signal bandwidth, and configuring which beam a wakeup signal may be received on.

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: 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 method for wireless communication includes: scheduling, by a wireless station, a first uplink (UL) transmission from a wireless device; determining, by the wireless station, a need for a higher priority uplink transmission that uses resources overlapping with the first UL transmission; determining, by the wireless station, a reference region, within which a UL cancellation indication (CI) is to be applied; determining, by the wireless station, a set of UL resources in the reference region for cancellation, wherein at least a subset of the UL resources in the reference region are interlaced; sending, via a downlink control channel, indication of the determined set of UL resources for cancellation (e.g., by indicating particular interlaces and/or particular Physical Resource Blocks within such interlaces that are to be canceled); and receiving, at the wireless station, the higher priority uplink transmission via at least a subset of the determined set of cancelled UL resources.
