Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses for using a media access control (MAC) control element (CE) for dynamic RLC entities selection. In one aspect, a base station (BS) may generate and transmit the control message to a user equipment (UE) to identify active radio link control (RLC) entities, a primary RLC entity, or other parameters relating to packet data convergence protocol (PDCP) duplication-based communication. In this case, the UE may use the control message to select an RLC entity and may transmit protocol data units (PDUs) to the BS using a data radio bearer (DRB) and the selected RLC entity.

Abstract: Wireless communications systems and methods relate to an automatic transmission scheme for a de-prioritized protocol data unit (PDU) when the originally assigned configured grant for the PDU is de-prioritized due to channel conflicts. Specifically, a user equipment may obtain a PDU for transmission over a first configured grant physical uplink shared channel (PUSCH) instance. The UE may then detect de-prioritization information that the first configured grant PUSCH instance is de-prioritized due to channel overlapping, and then automatically transmit the PDU originally associated with the first configured grant PUSCH instance over a second configured grant PUSCH instance.

Abstract: A user equipment (UE) may utilize multiple radio link control (RLC) entities to duplicate packet data convergence protocol (PDCP) packets for improved reception. The UE may receive a configuration for dual connectivity with a master cell group and with a secondary cell group, wherein the configuration identifies a plurality of configured RLC entities, each RLC entity being associated with one of the master cell group or the secondary cell group. The UE may receive, at the UE, an indication of an activation status for each of at least a first subset of the configured RLC entities from one cell group of the master cell group or the secondary cell group. The UE may set the activation status of each of the first subset of the configured RLC entities that are associated with the one cell group from which the indication is received based on the indication.

Abstract: Apparatus, methods and computer-readable media for broadcast of multiple physical cell identity ranges are disclosed herein. A user equipment (UE) can receive system information (SI) containing physical cell identities (PCIs) associated with a first cell type or a second cell type, in which the first cell type is accessible to a first set of UEs and the second cell type is accessible to a second set of UEs and a second set of PCIs containing PCIs corresponding to a set of cells of the second cell type. The UE can also monitor for cells with a PCI in the first set of PCIs or the second set of PCIs. A base station may generate the SI indicating the first set of PCIs and the second set of PCIs. Additionally, the base station can communicate the SI to one or more UEs.

Abstract: A wireless communication system is provided allowing a base station to indicate RTT compensation for UEs to adjust their local time clocks to correct propagation delay timing errors and synchronize with the global clock of a base station. A base station sends a downlink transmission including timing information to a UE and receives an uplink transmission from the UE after the downlink transmission. The base station determines a RTT compensation associated with the timing information based on a RTT between the downlink transmission and the uplink transmission. The base station then transmits the RTT compensation to the UE. UEs are thus allowed to synchronize at a high precision with the time clock of the base station. UEs may be configured with different resolutions or granularities in timing correction so that certain UEs can achieve high precision timing correction while other UEs can adjust their time clocks with less precision.
