  • Patent number: 11979877
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may reduce a transmission power of a scheduled downlink message relative to an expected transmission power of the scheduled downlink message in response to determining that the scheduled downlink message will cause at least a threshold level of interference with a concurrently scheduled uplink message. The base station may transmit the scheduled downlink message to a user equipment (UE) using the reduced transmission power and may transmit, to the UE an indication of a power adjustment for a downlink measurement of the scheduled downlink message. The UE may receive the indication after receiving the scheduled downlink message and may adjust the downlink measurement in accordance with the indication of the power adjustment.

    Abstract: Apparatuses and methods for indications of CLPC reset are described. An apparatus is configured to receive, from a network node, a MAC-CE or DCI that includes an indication of closed loop power control (CLPC) reset information. The apparatus is also configured to reset or maintain a CLPC adjustment state in response to receiving the indication of the CLPC reset information in the MAC-CE or the DCI. Another apparatus is configured to receive, from a network node, information for CLPC at the UE, where the information for CLPC indicates that a CLPC adjustment state is unaffected during a configuration for OLPC or a random-access at the UE. The other apparatus is also configured to maintain the CLPC adjustment state at the UE, during OLPC configuring or a random-access procedure at the UE, based on the information for CLPC received from the network node.

  • Patent number: 11973546
    Abstract: In some access networks, group-based beam reporting configured for a UE may be based on heuristics and/or based on UE implementation, and therefore, may lack adequate information regarding joint channel properties for simultaneous transmission and reception on a channel configured with a base station. Configurations of UEs and base stations are described herein that support various feedback metrics for resource grouping in association with transmission and reception operation modes and/or channel states, such as MIMO schemes, SINRs, channel properties, and the like. Base stations may dynamically indicate metrics to be reported by UEs so that simultaneous transmission and reception may be sufficiently supported.
