Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a radio resource control (RRC) inactive state of a discontinuous reception (DRX) mode. The UE may receive one or more synchronization signal blocks (SSBs) over a serving single frequency network (SFN) for a first notification zone, wherein the first notification zone comprises a plurality of cells. The UE may perform a channel measurement procedure using the received one or more SSBs. The UE may determine, based at least in part on a result of the channel measurement procedure, that a channel performance metric for the serving SFN of the first notification zone fails to satisfy a threshold. The UE may perform a cell reselection procedure to identify a cell of a neighboring SFN for a second notification zone that has a channel performance metric satisfying the threshold.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that a plurality of physical downlink shared channel (PDSCH) communications are associated for purposes of demodulation reference signal bundling. The UE may determine whether a phase continuity is to be maintained for the plurality of PDSCH communications based at least in part on respective quasi-co-location assumptions for the plurality of PDSCH communications. The UE may process the plurality of PDSCH communications based at least in part on whether the phase continuity is to be maintained Numerous other aspects are provided.

Abstract: A first UE may schedule a first sidelink transmission and a second sidelink transmission. A first DMRS associated with the first sidelink transmission and a second DMRS associated with the second sidelink transmission may be bundled for channel estimation associated with a second UE. The first UE may schedule a first uplink transmission. The first uplink transmission may be TDMed or FDMed with at least one of the first sidelink transmission or the second sidelink transmission. The first UE may transmit at least one of the first sidelink transmission, the second sidelink transmission, or the first uplink transmission. The bundling of the first DMRS and the second DMRS may be maintained or canceled.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may modify, based at least in part on a secrecy key, an input or an output of at least one of binary scrambling, modulation, or orthogonal frequency division multiplexing (OFDM) tone mapping for a physical control channel signal, resulting in a secured physical control channel signal. The transmitter device may transmit, to a receiver device, the secured physical control channel signal. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may encode an indication for demodulation reference signal bundling in a physical uplink shared channel (PUSCH) communication based at least in part on whether uplink control information (UCI) other than the indication is to be included in the PUSCH communication. The UE may transmit the PUSCH communication. Numerous other aspects are described.

Abstract: Aspects are provided which allow a first device to secure transmission of polar encoded control information by encoding at least a portion of frozen bits and/or information bits with a shared key with a second device before these bits are encoded by a polar encoder. The first device determines whether to encode at least one of a plurality of frozen bits or a plurality of information bits using the shared key. Based on the determination, the first device encodes the frozen bits and/or the information bits, and sends the encoded frozen bits and/or the encoded information bits to the second device. Since the receiving device has the shared key, the receiving device may successfully decode the control information, while an eavesdropper who receives the encoded bits may fail to decode the control information due to lack of knowledge of the shared key.

Abstract: Aspects of the present disclosure provide mechanisms for reducing the payload size of the channel state information (CSI) multiplexed together with deferred acknowledgement information. In some examples, a user equipment (UE) may transmit combined acknowledgement information including the respective acknowledgement information for one or more of received packets, along with turbo acknowledgement information including both the respective acknowledgement information and the respective CSI feedback for one or more remaining ones of the packets within an uplink resource.
