Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), operating in a serving cell, may adjust a transmit power of an uplink message when a neighboring cell is operating in an opposite direction (e.g., relative to the direction of communications in the serving cell) within a same or similar frequency band in a same time period. The UE may receive control signaling that indicates a first power control configuration to be used when the neighboring cell is operating in a same direction as the serving cell and a second power control configuration to be used when the neighboring cell is operating in a different direction from the serving cell. The UE may select the appropriate power control configuration based on the communications directions of the serving cell and the neighboring cell and may transmit the uplink message in accordance with the selected power control configuration.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to determine a time gap between receiving a paging early indication (PEI) and receiving a paging message based on a link quality of the UE. The UE may determine the time gap based on a number of reference signals the UE may measure after receiving the PEI to obtain channel information for accurately decoding a forthcoming paging message and a periodicity of the reference signals. The UE may transmit UE assistance information (UAI) to the base station during an active state to indicate the time gap. The UE may receive a configuration message from the base station indicating a configured time gap for the UE based on the UAI. The UE may receive the PEI and monitor a paging occasion for the paging message according to the configured time gap.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured for discontinuous reception (DRX) operations using wakeup signals. The UE may monitor periodic wakeup signal occasions for wakeup signals and, in the event that the UE detects a wakeup indication that the UE is to initiate an active duration, the UE may power on transmit/receive circuitry for communications with a base station. In an absence of receiving the wakeup indication, the UE may be configured to transmit an uplink reference signal (e.g., a sounding reference signal) to the base station in an inactive duration of a DRX cycle in some cases. The uplink reference signal may be measured at the base station and used to determine one or more parameters for subsequent communications with the UE.

Abstract: Aspects are provided which allow coverage enhancement and support in NTNs for repetition, frequency hopping, and antenna switching during msgA transmissions based on a preamble-to-PO mapping. In one aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with at least one PO for two-step random access, where the PO spans a time interval greater than one slot. In another aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with a plurality of POs for two-step random access. In a further aspect, the base station provides the UE a plurality of configurations each indicating a PO for two-step random access. In an additional aspect, the base station provides the UE a configuration indicating a guard band for a PO for two-step random access, where the guard band is indicated in units of subcarriers spanning less than one PRB.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.
