Abstract: Certain aspects of the present disclosure provide techniques and apparatus for operations with switching active bandwidth parts (BWPs), such as for radio link monitoring (RLM), beam failure recovery, random access, and/or other operations. As described herein, a UE may be configured with one or more sets of BWPs. The UE may determine/select the uplink and/or downlink BWP to use. For example, the UE can determine to use an active BWP or to switch to another BWP. The UE may use the BWP during operations, such as RLM, beam failure recovery, and/or random access, etc. for monitoring on the downlink and/or for transmitting on the uplink.

Abstract: Aspects of the present disclosure describe receiving synchronization signals in wireless communications. A block of synchronization signals can be received from a base station in a first time interval. A beam identifier and a redundancy version associated with the block of synchronization signals can be determined. A broadcast channel can be received based at least in part on a timing associated with the beam identifier. The broadcast channel can be descrambled based at least in part on a scrambling code associated with the redundancy version.

Abstract: Methods, systems, and devices for wireless communications are described that provide for selection of different sets of transmission beams by a user equipment (UE) for establishing beamformed communications with a base station. Each transmission beam of a first set of transmission beams may have corresponding uplink random access channel (RACH) resources. A UE may monitor for transmission beams from a base station and select a first transmission beam of the first set for communications with the base station. As part of a connection establishment, the base station may provide configuration information that indicates a second set of transmission beams that includes each transmission beam of the first set of transmission beams and at least an additional transmission beam. In some cases, the additional transmission beam may be mapped to a first RACH resource that also corresponds to a first transmission beam of the first set of transmission beams.

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: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a communication that includes system information, wherein the system information includes information associated with identifying a set of resources that carry synchronization communications, wherein the set of resources is included in a set of potential resources on which synchronization communications can be carried; and perform, based at least in part on a rate matching rule, de-rate matching associated with receiving the system information, wherein the rate matching rule is a rule associated with performing de-rate matching with respect to the set of potential resources. 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.
