Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may communicate with a base station using multiple receivers and receive an indication from the base station to activate a second bandwidth part of a set of bandwidth parts configured for the UE. In response to the indication, the UE may switch from operating in a first bandwidth part to operating in the second bandwidth part and adjust a quantity of active receivers at the UE based on switching from operating in the first bandwidth part to operating in the second bandwidth part. Additionally or alternatively, the UE may adjust the quantity of active receivers at the UE based on monitoring for downlink grants from the base station.

Abstract: Disclosed are techniques for wireless communication. In an aspect, BS transmits first and second configurations for first and second BWPs to UE. The first BWP is set as an active BWP based on the first configuration. BS transmits TCP command(s) that set an active power control adjustment state. BS transitions the active BWP from the first BWP to the second BWP based on the second configuration. The active power control adjustment state is maintained after the active BWP transition (e.g., not reset to some default state).

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support random-access occasion (RO) selection for reduced-capability (RedCap) user equipment (UEs). A RedCap UE operating in a half-duplex mode may use the techniques described herein to efficiently select an RO in which to transmit a random-access preamble based on a duration between a latest received downlink transmission and the RO satisfying a threshold duration. The UE may receive system information mapping a set of synchronization signal blocks (SSBs) to a set of ROs. The UE may then select an RO from the set of ROs in which to transmit the random-access preamble such that the UE has sufficient time to transition from a receive mode to a transmit mode to transmit the random-access preamble.

Abstract: Dynamic User Equipment (UE) beam switching for millimeter wave (mmWave) measurements in asynchronous networks is discussed in which a UE configured with a plurality of UE beams receives timing information of detected cells in an asynchronous network, and calculates, based on the timing information, a maximum offset for the detected cells indicating a timing difference between a pair of cells of the detected cells that is larger than a timing difference between any other pair of the detected cells. A UE beam switch from a UE beam to another UE beam of the plurality of beams is scheduled based on the maximum offset, which includes using the maximum offset to determine how often the UE beam switch can be performed. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a first configuration indicating for the UE to communicate with the base station using a set of receive ports. The UE may transmit, according to the first configuration in a first time interval associated with a first power state of the UE, sounding reference signals (SRSs) on a set of transmit ports corresponding to the set of receive ports. The UE may then communicate using less than all of the set of transmit ports for the SRSs based on determining to operate in a reduced power state. The UE may then receive, based on communicating using less than all of the set of transmit ports for the SRSs, a second configuration indicating for the UE to communicate with the base station using a first subset of receive ports.

Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE). The method generally includes: identifying at least one indicator to conserve power; and in response to the identification, determining to skip one or more periodic or semi-persistent measurements of a signal from a cell based on at least one criteria.

Abstract: The present disclosure relates to methods and devices for communication which may include a user equipment (UE) and a base station. In one aspect, the UE may receive a trigger to measure an uplink Aperiodic Channel State Information Reference Signal (A-CSI-RS). The UE may also receive an allocation of a first resource for an uplink shared channel. Additionally, the UE can receive at least one indication for an A-CSI report to comprise a null A-CSI report. Moreover, the UE can determine whether to alter another uplink transmission. In some aspects, this determination can be based, at least in part, on whether the first resource allocated for the uplink channel overlaps in time with a second resource for the other uplink transmission.

Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.

Abstract: One or more aspects of the disclosure provide an efficient equalization scheme capable of mitigating multi-path interference on channels with large delay spread using short-length equalizers. That is, by dividing stored samples of a signal received on the multi-path channel by time into a plurality of clusters, a short-length equalizer can be utilized in an iterative fashion on each of the clusters, thus eliminating the need for a large length equalizer while still providing improved performance over that of a Rake receiver at large delay spreads. Other aspects, embodiments, and features are also claimed and described.
