Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a second communication, of a bandwidth part (BWP) selection process, that indicates a subset of BWPs, of a set of BWPs, to be selected as a set of active BWPs, wherein the set of BWPs is configured to the UE for a component carrier via radio resource control signaling as a first communication of the BWP selection process, wherein the subset of BWPs includes one or more BWPs of the set of BWPs. In some aspects, the UE may select the subset of BWPs as the set of active BWPs based at least in part on receiving the second communication, wherein a particular BWP, of the subset of BWPs, is to be used for a post-BWP selection process communication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support slot format determination for extended cyclic prefix (ECP) transmissions using normal cyclic prefix (NCP) slot formats. A slot format indicator (SFI) for NCP slots may identify transmission directions (e.g., uplink symbols, downlink symbols, or flexible symbols) for different symbols within a slot, and the SFI may provide an indication of a particular slot format that is to be used. Starting and ending times of each NCP symbol in a slot may be time domain mapped to starting and ending times of each ECP symbol in the slot. A transmission direction of each ECP symbol may be determined based at least in part on the transmission direction of at least a portion of at least one NCP symbol that fully or partially overlaps in the time domain with a corresponding ECP symbol.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may be configured to transition to communicating on a first bandwidth part from communicating on a second bandwidth part. In order to ensure that the UE is able to perform receiver processing for demodulating data received on the first bandwidth part, after transitioning to communicating on the first bandwidth part, the UE may be configured to perform receiver processing using reference signals received on the second bandwidth part. That is, for a configured period of time, before the UE is able to perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the first bandwidth part, the UE may perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the second bandwidth part.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a communication that includes downlink control information (DCI), wherein a size of the DCI affects a cyclic redundancy check (CRC) value associated with the communication; and determine the DCI or the size of the DCI based at least in part on the CRC value. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may observe control channel monitoring occasions (PMOs) corresponding to different beams configured by a base station. The UE may identify a PMO in a system information window to monitor for downlink control information scheduling a shared channel carrying a system information message. The UE may receive an indication of which synchronization signal/physical broadcast channel (SS/PBCH) blocks are actually transmitted by the base station and determine corresponding PMOs within the system information window. The UE may then monitor for the downlink control channel within the system information window during the corresponding PMOs. The base station and the UE may also implement techniques for system information message repetition within a system information window.

Abstract: Methods, systems, and devices for wireless communications are described that support time division duplexing (TDD) for dual connectivity (DC) to different radio access networks (RANs). A DC connection may be established between a user equipment (UE) and both a first RAN and a second RAN. A reference TDD configuration for the first RAN and a designated TDD configuration for both the first and second RAN may be identified. The designated TDD configuration may have a first set of uplink subframes and the reference TDD configuration may have a second set of uplink subframes that is a subset of the first set of uplink subframes. Downlink transmissions of the first RAN may be transmitted according to the reference TDD configuration, and uplink transmissions of the first and second RAN may be transmitted according to the designated TDD configuration.

Abstract: Aspects and techniques relate to scheduling resources for uplink transmissions in wireless communication systems. In some examples, an allocation of resources for uplink may be based on a common reference resource (e.g., a reference physical resource block, PRB) also used for allocation of resources for downlink In other examples, allocation of resources for uplink may be based on a different reference resource. A scheduler may further provide an indication whether the same, common reference resource is used, or a different reference resource. A scheduler may further indicate a different reference resource as needed. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive scheduling information for a transmission associated with a particular radio access technology (RAT) of a 4G RAT or a 5G RAT, wherein the scheduling information identifies a particular resource of one of a first set of resources for the 4G RAT or a second set of resources for the 5G RAT, wherein one or more resources of the first set of resources are guaranteed for the 4G RAT based at least in part on a reference 4G time division duplexing (TDD) configuration, and wherein the one or more resources of the first set of resources and the second set of resources do not overlap in a time domain; and transmit or receive the transmission using the particular resource. Numerous other aspects are provided.

Abstract: Techniques and apparatuses described herein permit selective multiplexing of synchronization signal blocks (SSBs), inside of or outside of an SSB measurement timing configuration (SMTC) window, and downlink channel communications depending on one or more factors, which may increase spectral efficiency due to multiplexing when permitted, and may prevent or reduce collisions and interference when not permitted (e.g., due to quasi co-location constraints, processing constraints, timeline constraints, and/or the like).
