Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple different receive beams at a user equipment (UE) that may be spatially associated with a single transmission beam from a base station. A UE may measure, using multiple different receive beams, multiple instances of a same reference signal transmitted by the base station using a same transmission beam. The UE may provide measurement reports associated with each of the measurements to the base station. A particular receive beam to be used for a downlink transmission may be selected from the multiple receive beams and may be indicated to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first transmission/reception point (TRP) may coordinate with a second transmission/reception point to configure code division multiplexing group hopping for a user equipment (UE). The first TRP may transmit a signal to the UE indicating that code division multiplexing group hopping is enabled for the first transmission/reception point and the second transmission/reception point. The first TRP may transmit, during a first instance of the code division multiplexing group hopping, a first reference signal to the UE according to a first code division multiplexing group. The first TRP may transmit, during a second instance of the code division multiplexing group hopping, the first reference signal to the UE according to a second code division multiplexing group.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may transmit, to a second device, reference signals using combinations of analog beamforming parameters over multiple cycles. The reference signals may be transmitted for different combinations of transmit beamforming parameters and receive beamforming parameters over different cycles of the multiple cycles. The first device may receive, from the second device over the multiple cycles, a set of reports. Each report may indicate combinations of analog beamforming parameters selected for the analog beamforming parameters at the second device. Each combination of analog beamforming parameters may correspond to different cycles of the multiple cycles. The first device may set, for each radio frequency (RF) chain of a plurality of RF chains associated with the first device, a corresponding combination of analog beamforming parameters, and communicate with the second device via two or more beams based on the setting.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use one or more antenna subarrays to perform a scheduling request (SR) operation with one or more corresponding transmission reception points (TRPs) while operating in a connected discontinuous reception mode. In some implementations, the UE may receive a configuration indicating a set of its antenna subarrays and a corresponding set of the TRPs with which to perform the SR operation. Based on this configuration, the UE may transmit an SR to the set of TRPs using the set of its antenna subarrays, receive an uplink grant from at least one TRP of the set of TRPs, and transmit uplink data to the at least one TRP. Additionally or alternatively, the UE may determine the sets of antenna elements and TRPs for the SR operation autonomously and transmit an indication of this determination when transmitting the SR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a serving base station may identify that the UE is a potential victim of interference from a neighboring base station. The UE may transmit an interference coordination message to the neighboring base station. The interference coordination message may request modification of one or more transmission parameters at the neighboring base station. The neighboring base station may modify its transmission parameters to decrease interference with the UE, and the UE may communicate with the serving base station after transmitting the interference coordination message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a random access channel (RACH) signature from among one or more RACH signatures associated with a synchronization signal block (SSB). The UE may transmit, to a base station (BS), a RACH communication using the selected RACH signature. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control message that schedules a downlink signal on a second carrier for the UE. The UE may determine a transmission scheme of a plurality of transmission schemes based at least in part on the first carrier, the second carrier, and a second transmission reception point scheduled for transmission of the downlink signal. The UE may determine a delay between the downlink control message and the downlink signal based at least in part on the transmission scheme and receive the downlink signal via the second carrier in accordance with the determined delay.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability to receive a first portion of a tracking reference signal (TRS) and a second portion of the TRS, the first portion and the second portion associated with a TRS pattern. The UE may receive, from the base station, an indication of the TRS pattern, where the TRS pattern includes the first portion of the TRS pattern and the second portion of the TRS pattern. The UE may receive one or more TRSs according to the first portion of the TRS pattern and the second portion of the TRS pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a signal to a base station indicating a UE capability configuration. The UE may receive, over an unlicensed radio frequency spectrum band, a wakeup signal during a monitoring period, the wakeup signal indicating that wireless communications are to be performed between the UE and the base station during an active time period. The UE may identify a guard time period upon receiving the wakeup signal, wherein the guard time period is based at least in part on the UE capability configuration. The UE may perform, after an expiration of the guard time period, the wireless communications with the base station during the active time period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a candidate pattern from a set of patterns for reference signals used to track phase error. The UE may transmit an indication of the selected pattern to a base station and receive, from the base station at least in part in response to the transmitted indication of the selected pattern, an indication of a configuration for the reference signals used to track phase error, the configuration indicating a pattern of the set of patterns, a number of reference signal groups, and a number of samples per reference signal group. The UE may receive the reference signals used to track phase error according to the indicated configuration.
