  • Publication number: 20240040522
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multiplexing and prioritization techniques for uplink signaling and non-serving cell synchronization signals. In some aspects, a user equipment (UE) and a network entity may support a prioritization rule according to which the UE and the network entity may enable uplink multiplexing with a set of non-serving cell synchronization signal blocks (SSBs). For example, an uplink signal and a set of non-serving cell SSBs may be scheduled for the UE and may at least partially overlap in time and the UE may prioritize one of the uplink signal or the set of non-serving cell SSBs in accordance with the prioritization rule. The prioritization rule may be associated with a scheduling offset of the uplink signal or may be associated with whether the set of non-serving cell SSBs are indicated for measurement at the UE.

  • Patent number: 11889359
    Abstract: When a beam failure is detected, appropriate actions may be taken to recover the connection. A beam failure recovery request may be sent by a user equipment (UE) apparatus to initiate the recovery of the connection. The UE detects a beam failure for at least one active downlink and uplink beam pair for full duplex communication with a secondary cell (SCell). The UE transmits a beam failure recovery request (BFRQ) for the SCell to a base station using an uplink resource of the SCell or a primary cell (PCell) based on a layer 1 signal to interference and noise ratio (L1-SINR) measurement for the at least one active downlink and uplink beam pair of the SCell.

  • Patent number: 11871404
    Abstract: Aspects relate to techniques for mitigating wireless communication interference. For example, one or more of a cyclic prefix length, a subcarrier spacing, a beam pair, or a frequency domain separation may be changed to mitigate the effects of inter-symbol interference (ISI) at a UE or a base station. A UE may measure a received timing difference between a time at which the UE receives a downlink transmission and a time at which energy from an uplink transmission by the UE is received by the UE. If this received timing difference exceeds a specified duration of time (e.g., the length of a cyclic prefix), the ISI at the UE may increase. In some examples, the interference mitigation techniques described herein may be invoked if there is an increase in the measured received timing difference.
