Abstract: A configuration for a UE that measures CLI to determine the reception timing of the CLI signal transmitted from a UE in another cell. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of measuring CLI signals by improving the manner in which a wireless device determines the reception timing of a transmitted CLI signal. An apparatus receives a first downlink signal from a first base station. The apparatus receiving a second downlink signal from a second base station. The apparatus determines a CLI signal measurement from a second UE received at the first UE based on a propagation delay difference, the propagation delay difference being based on the first downlink signal and the second downlink signal.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support enhanced scheduling request configurations. A user equipment (UE) may obtain, at a packet data convergence protocol (PDCP) layer of the UE, information associated with a data packet for transmission by the UE. The UE may transmit a scheduling request that indicates information regarding an elapsed time period since the information associated with the data packet was obtained at the PDCP layer of the UE, or whether the data packet is a final packet of a set of data packets, or both. A network entity may receive the scheduling request and determine scheduling information for uplink communications by the UE based on the information regarding the elapsed time period, or whether the data packet is the final data packet, or both. The network entity may transmit the scheduling information to the UE.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may operate by asynchronously transmitting code division multiple access (CDMA) uplink signals to a network entity. The UE may transmit the CDMA signals via an uplink channel that may be shared with orthogonal frequency multiplexing (OFDM) signaling transmitted by one or more other UEs. The UE may indicate to the network entity a capability for communicating with CDMA waveforms and may use CDMA waveforms based on transmitting the indication. The UE may also receive one or more parameters associated with using the CDMA waveforms, and may use CDMA waveforms based on the one or more parameters. The uplink channel may be a random access channel (RACH) and may support RACH transmissions, or may be a data channel and support data transmissions.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to be in agreement on spatial quasi co-location (QCL) assumptions for transmission in certain scenarios. The techniques may be used, for example, to determine QCL assumptions for downlink transmissions sent in an initial control resource set (CORESET) on an initial downlink bandwidth part (BWP) where dedicated signaling of such assumptions may be lacking. In some cases, the techniques may involve a UE determining a beam to use for monitoring for a physical downlink control channel (PDCCH) transmission on the initial CORESET in the initial downlink BWP that lacks dedicated signaling of QCL information and monitoring for the PDCCH on the initial CORESET in the initial BWP using the determined beam. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A serving base station or a serving satellite may transmit a timing configuration to the UE based on a reference unit, such as a location at a beam center for a respective satellite, a threshold distance relative to the beam center for the respective satellite, a reference time, or any combination thereof. In some cases, the UE may monitor for one or more SSBs from the neighboring satellites according to the timing configuration and a respective propagation delay between the UE and each of the neighboring satellites. The UE may measure the SSBs according to the measurement gap and measurement window in the timing configuration. In some examples, the UE may perform a cell handover procedure or a cell reselection procedure based on measuring the SSBs.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive a control message that includes an indication to mute communications between the first UE and a second UE. The indication may be applicable to at least one communication link between the first UE and the second UE. The indication may include an identifier of the first UE, an identifier of the second UE, or an identifier of the at least one communication link. The first UE may receive the indication based on a power status of the first UE, a power status of the second UE, a reliability metric associated with the at least one communication link, or an interference metric associated with a network entity. Accordingly, the first UE may determine that the at least one communication link is muted for a time duration based on the indication.

Abstract: In a wireless network, a base station may configure a victim user equipment (UE) experiencing interference with a periodic measurement resource using Layer 3 (L3) signaling, and the UE may report cross-link interference (CLI) measurements to the base station using L3 messages. However, using L3 signaling to configure interference measurement and reporting may result in an inflexible interference measurement configuration and a long latency to report CLI and/or self-interference feedback. Furthermore, although Layer 1 and/or Layer 2 (L1/L2) CLI reporting may be more suitable to track and adapt to dynamic changes in interference conditions, L1/L2 signaling increases control signaling and CLI management overhead at the base station. Accordingly, some aspects described herein relate to an adaptive L3 CLI measurement and reporting framework, where L3 messages may include one or more adaptive fields to support flexibility in configuring CLI measurement and/or CLI reporting parameters.
