Abstract: Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

Abstract: Beam management for the downlink can be based on user equipment (UE) measurement of downlink (DL) reference signal (RS) and UE reporting. An alternative approach that may reduce overall RS overhead and latency is BM for the downlink based on uplink (UL) RS. With this approach, the network measures UL RS transmissions on multiple beams and uses these measurements for managing beams for the DL. Disclosed herein are various problems and enhancements related to UL RS based DL BM, in particular beam failure detection and recovery.

Abstract: In Methods, apparatus, and systems are described for improved beam management and multi-beam operation for 5G New Radio (NR). According to some aspects, spatial coverage may be enhanced for user equipment (UE) for NR from 52.6 GHz and above. A UE may receive a plurality of Transmission Configuration Indication (TCI) states, wherein each of the TCI states corresponds to a Physical Downlink Control Channel (PDCCH) or a plurality of scheduled Physical Downlink Shared Data Channel (PDSCH). The UE may determine a channel estimator for channel estimation by combining each of the TCI states.

Abstract: Configured uplink and/or downlink grants may be managed by providing configuration parameters through higher layer signaling and then activating and/or deactivating use of provided configurations through group common PDCCH signalling that is transmitted to multiple UEs simultaneously. Similarly, enhancements to group common PDCCH signalling may be used to achieve dynamic scheduling.

Abstract: A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

Abstract: Sub-band (SB) indications and listen-before-talk (LBT) outcomes may be used to adjust communications between devices such as wireless terminals and base stations. For example, a wireless terminal may receive SB indications including SB configurations and/or LBT outcomes of a base station, and other information such as a remapped CORESET. Similarly, a terminal may determine that a physical resource block (PRB) is invalid based at least in part on whether the PRB overlaps with a guard band. The terminal may be arranged to adjust its searches and transmissions based on received SB indications, and to provide the base station with LBT outcomes of the terminal.

Abstract: Multicast/Broadcast Service (MBS) for user equipments (UE) in Radio Resource Control (RRC) idle/inactive modes via signally of MBS frequency ranges and/or switching between frequency ranges as required. Bandwidth Part (BWP) operation for MBS in RRC IDLE and RRC INACTIVE states may be implemented using a dedicated MBS BWP or by sharing a frequency range with other operations. An MBS frequency range may be wider or narrower than an initial BWP used by a UE, for example. MBS frequency range configure may be achieved in a number of ways, such as via Control Resource Set (CORESET), search space, and/or PDCCH monitoring occasions pattern settings for MBS in RRC idle/inactive. Downlink scheduling without dynamic grant for MBS in RRC idle/inactive may include configured scheduling and/or semi-persistent scheduling.
