Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a connection release message, the connection release message including a resource indicator indicating that a set of resources are to be used for grant-free uplink transmissions by the UE while operating in a disconnected state. The UE may transition from a connected state to a disconnected state based at least in part on the connection release message. The UE may perform, while operating in the disconnected state, the grant-free uplink transmissions using the set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first synchronization signal for synchronizing with a cell, the first synchronization signal transmitted at a first periodicity by a base station serving the cell. The UE may then receive, subsequent to the synchronizing, a second synchronization signal for resynchronizing with the cell. In some cases, the second synchronization signal may be transmitted by the base station according to a second periodicity that is different from the first periodicity. In some cases, the second synchronization signal may include a plurality of repetitions of a first sequence that is based at least in part on a cell identifier of the cell. The UE may communicate over the cell with the base station based at least in part on the resynchronizing.

Abstract: Some techniques and apparatuses described herein provide bandwidth, coverage extension/repetition schemes, and synchronization signal burst set periodicities for low-cost UEs. For example, some techniques and apparatuses described herein provide particular repetition resources within a broadcast channel and/or synchronization signal block, particular repetition resources in consecutive slots, and/or the like. Furthermore, some techniques and apparatuses described herein define minimum bandwidths of low-cost UEs in relation to non-low-cost UEs, and define synchronization signal burst set periodicities that may be different for low-cost UEs than for non-low-cost UEs.

Abstract: Aspects described herein relate to communicating with one or more cells for receiving a broadcast service, and providing broadcast service continuity in device mobility scenarios. In some aspects, a user equipment (UE) can transmit a broadcast service interest indication to a serving cell to facilitate receiving the broadcast service during mobility to provide the broadcast service continuity.

Abstract: A base station multicasts a physical downlink shared channel (PDSCH) transmission and transmits downlink control associated with the PDSCH, wherein the downlink control comprises different parameters for uplink transmissions to multiple user equipments (UEs). A UE receives the associated the PDSCH, where the downlink control comprises different parameters for uplink transmissions to multiple UEs including an uplink transmission parameter for the UE. The UE receives the multicast PDSCH and transmits the uplink transmission based on the uplink transmission parameter for the UE and the multicast PDSCH.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may transmit a plurality of repetitions of a cell-common wakeup signal (WUS) on a different transmit beam in each monitoring occasion of one or more monitoring occasions. Another apparatus may beam sweep receive beams in each monitoring occasion to receive the cell-common WUS and to identify a transmit beam/receive beam pair for receiving a paging communication in a paging occasion associated with the transmit beam.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for maximizing the potential of resources dedicated to aerial user equipment (UEs). In one example, a UE may receive signaling indicating that a cell supports communications exclusively with aerial UEs. The signaling may be used to bar non-aerial UEs from accessing the cell and reserve resources for communications with aerial UEs. In another example, a UE may receive signaling identifying one or more frequency bands dedicated to aerial UEs. The UE may then communicate on the one or more frequency bands. In yet another example, a UE may receive signaling indicating a set of aerial access categories supported by a cell. The signaling may be used to reserve resources for high-priority aerial UEs (e.g., aerial UEs used for law enforcement purposes).

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of subcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool, a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations within a resource pool in the same bandwidth part.
