Abstract: A user equipment (UE) may request to change its radio resource control (RRC) parameters by transmitting a UE assistance information message to a base station. However, the existing RRC parameters that a UE may request to change via a UE assistance information message may not be inadequate for some UEs and may cause a high signaling overhead. The aspects described herein include an apparatus that obtains configuration information for a UE assistance information message, the configuration information indicating a set of parameters the apparatus is allowed to indicate in the UE assistance information message, the set of parameters including at least one of an operation complexity control parameter, a network coverage control parameter, or a channel monitoring control parameter. The apparatus transmits the UE assistance information message, wherein the UE assistance information message is based on at least a portion of the set of parameters.

The first group may include the first UE. The first Tx power may have a first power level different from a second power level of a second Tx power for one or more second DL transmissions to a second group of the plurality of groups. Then, the base station may transmit, to the first UE, a first DL transmission of the one or more first DL transmissions using the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a system information block (SIB) indicating a plurality of subband configurations. The UE may identify, based at least in part on one or more of the plurality of subband configurations, one or more uplink subbands in a time division duplexing (TDD) component carrier and one or more downlink subbands in the TDD component carrier. The one or more uplink subbands and the one or more downlink subbands may be frequency division duplexed within the TDD component carrier. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a single downlink control information (DCI) message that schedules communications on multiple cells, wherein the single DCI message indicates multiple time domain resource assignments (TDRAs) corresponding to the multiple cells, wherein each of the multiple TDRAs corresponds to a different scheduled communication; and communicate using the multiple TDRAs corresponding to the multiple cells, wherein the communicating comprises: transmitting the communications using the multiple TDRAs corresponding to the multiple cells, or receiving the communications using the multiple TDRAs corresponding to the multiple cells. Numerous other aspects are provided.

Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for interference measurement and reporting by a UE. The interference measurement can be self-initiated by the UE or based on a request received from a BS. To measure the interference, the UE transmits a first signal in UL resources to a first BS concurrently with receiving a second signal in DL resources from one of the first BS or a second BS. The received second signal includes interference associated with the transmitted first signal. Based on the received second signal, the UE determines a level of the interference that is associated with the transmitted first signal. Information associated with the level of the interference is then transmitted to the first BS, such as an indication of a guard band that is to be incorporated between the UL resources and the DL resources.
