Abstract: This disclosure provides systems, methods, and devices for wireless communication that support dormant bandwidth part (BWP) configurations that may be used for full-duplex operation. In a first aspect, a user equipment (UE) in a full-duplex mode may, in at least one symbol, receive a downlink signal in a dormant downlink BWP and transmit an uplink signal in an uplink BWP. In a second aspect, a dormant downlink BWP may be further configured into one of multiple possible resource bandwidths (RBWs), which may include at least one dormant RBW. Each of the multiple RBWs that may be configured in the dormant BWP may be associated with a size and location as well as a set of one or more operational constraints. In a third aspect, a dormant downlink BWP may be further configured into one of multiple possible RBWs, which may include a downlink dormant RBW and an uplink dormant RBW.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to a network entity indicating a configuration for a user equipment (UE) for wake up radio signaling when the main radio of the UE is in a sleep mode. The UE may monitor for and receive, using the wake up radio, a wake up signal, a low power reference signal, or a low power synchronization signal from a second UE in accordance with the configuration. If the UE receives a wake up signal from the second UE, the UE may establish communications with the second UE or with the network entity based on the wake up signal.

Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may detect interference, in a remote interference management (RIM) scenario, in a set of sub-bands of a plurality of sub-bands of a bandwidth portion. The base station may transmit, to identify the set of sub-bands in which interference is detected, a set of reference signals configured to indicate the set of sub-bands in which the interference is detected. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may release a connection with a first network entity and determine a first virtual coverage area of the UE based on a geographic location of the UE associated with the release of the connection. The UE may obtain a message that includes area information. The area information may be indicative of one or more second virtual coverage areas, which the UE may use in determining whether to monitor for a paging early indication (PEI). Based on the first virtual coverage area and the one or more second virtual coverage areas may monitor for a paging message, such as the PEI or downlink control information (DCI) associated with a paging occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross-link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine a grant for performing uplink transmissions based on a radio resource control (RRC) message. The UE may determine, based on the downlink configuration, the grant, or both, an uplink configuration including a set of resources for transmitting the uplink transmissions at a set of uplink transmission occasions. In some aspects, the set of uplink transmission occasions may be arranged according to a non-uniform spacing pattern in a time domain. The UE may transmit, to a base station, one or more uplink transmissions based on the uplink configuration.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes determining whether a plurality of beam configurations configured for processing one or more downlink (DL) signals are different than a first beam configuration for processing at least one CSI-RS, the one or more DL signals to be received in the same symbol as the at least one CSI-RS; selecting a second beam configuration for processing the at least one CSI-RS based on the determination; receiving the at least one CSI-RS; and processing the at least one CSI-RS based on the selected second beam configuration.
