Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a physical channel such as a narrowband physical broadcast channel (NPBCH) to supplement (e.g., or as an alternative to) reference signal measurements when determining a received signal measurement, such as a received signal strength or received signal quality of a cell. A base station may transmit an indication to a UE that identifies the frequency at which a portion of NPBCH transmissions (e.g., reserved fields of a master information block (MIB)) is expected to change from one NPBCH transmission to another. The UE may adjust its utilization of NPBCH for determining the received signal measurement based on the indication. Further, the UE may communicate with the cell based on the determination of the received signal measurement, which are based on the indication.

Abstract: A method, an apparatus, a base station, a user equipment (UE), and a computer program product for wireless communication are provided. The base station may encode a wakeup signal so that a preamble of the wakeup signal indicates whether the wakeup signal is relevant to the UE. The UE may select a technique for detecting the wakeup signal based at least in part on a partial, full, or no synchronization. In some aspects, the wakeup signal may be encoded with a system frame number. In some aspects, wakeup signals for guardband/standalone UEs are provided. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate configuration, or reconfiguration of PUR allocation for the UE that may be used for uplink transmissions, or release of the PUR allocation.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.

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.
