The UE may participate in one or more mitigation actions to mitigate an effect of a nonlinear interference associated with the uplink transmission on a scheduled downlink signal that temporally overlaps with the uplink transmission. Additionally, or alternatively, the UE may receive an indication associated with a likelihood that one or more transmissions will occur, where the one or more transmissions temporally overlap with a downlink signal at the UE and are associated with nonlinear interference that potentially overlaps with the downlink signal. The UE may participate in, and receive the downlink signal in accordance with, one or more mitigation actions to mitigate an effect of the nonlinear interference on the downlink signal.

The first UE may decode the DL transmission based on at least a portion of the IC information for the UL transmission from the second UE.

Abstract: This disclosure provides methods, components, devices and systems for multi-port communications for downlink broadcast signaling. A user equipment (UE) may transmit or receive one or more signals that enable multi-port downlink broadcast signal communications. Thus, the UE may receive, via a first port of multiple ports of the UE and based on enablement of the multi-port downlink broadcast signal communications, a first downlink broadcast signal from a network entity. Additionally, the UE may receive, via a second port of the multiple ports and based on enablement of the multi-port downlink broadcast signal communications, a second downlink broadcast signal from the network entity, where the first port is different from the second port. In such cases, the first downlink broadcast signal and the second downlink broadcast signal may be received prior to reception, from the network entity, of a radio resource control message that indicates first configuration information for the UE.

In some cases, a user equipment (UE) may transmit or receive one or more signals that enable multi-port random access channel (RACH) transmissions and, thus, may transmit a RACH message via multiple ports of the UE based on multi-port RACH transmissions being enabled. For example, the UE may transmit, via a first port of the multiple ports, a first portion of the RACH message indicative of a first subset of sequences and may transmit, via a second port of the multiple ports, a second portion of the RACH message indicative of a second subset of sequences. In such cases, each of the first subset of sequences and the second subset of sequences may include multiple repetitions of a same sequence.

In some wireless communication systems, a first network node may transmit, prior to being radio resource control (RRC)-connected with a second network node, a first message indicating a first capability of the first network node to support full-duplex communications. After transmitting the first message and while RRC-connected with the second network node (and before, during, or after exchanging data with the second network node), the first network node may transmit one or more second messages indicating a second capability of the first network node to support full-duplex communications. The second capability may update or change the first capability indicated via the first message. The first network node and the second network node may communicate in accordance with the second capability indicated in one of the second messages.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques may enable a user equipment (UE) to receive control signaling indicating a first signal strength threshold and a second signal strength threshold that define multiple signal strength groups. The control signaling may further indicate a quantity of reference signal beams for each group of the signal strength groups for the UE to report. In some examples, the UE may report a quantity of reference signals for each group per antenna module of the UE. Reporting a combination of reference signal beams with relatively high and relatively low signal strengths relative to the signal strength thresholds, may enable a network entity to schedule resources more efficiently.
