Methods, apparatuses, and computer-readable storage medium for wireless communication are provided. An example method may include transmitting, to a network entity, a capability for a transmission of one or more positioning SRS outside of an initial UL BWP during an idle state or an inactive state of the UE. The example method may further include receiving, from the network entity, a configuration for the transmission of the one or more positioning SRS outside of the initial UL BWP during the idle state or the inactive state. The example method may further include transmitting, to the network entity based on the configuration, the one or more positioning SRS outside of the initial UL BWP.

SRS positioning BWP in RRC inactive or idle positioning

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.

Random-access occasion selection for reduced-capability user equipment

Aspects of the present disclosure provide techniques that may be utilized by a UE for performing neighbor cell measurement and reselection in narrowband deployment scenarios, such as NB-IoT deployment scenarios. For example, a method for wireless communications by a user equipment (UE), can include determining, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters of at least one neighbor cell, and performing a neighbor cell search with measurement of narrowband reference signals (NRS) based on the one or more transmission deployment mode parameters.

Neighbor cell measurement and reselection for narrowband operation

Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

Receive diversity techniques in wireless communications

Various aspects of the present disclosure generally relate to systems, apparatuses, and methods for beam determination prior to an indication of an activated beam. A user equipment may receive a configuration for one or more transmission configuration indicator (TCI) states; receive downlink control information that schedules a downlink transmission after a time offset; determine, prior to receiving an indication of an activated TCI state of the one or more TCI states, a beam for receiving the downlink transmission; and receive the downlink transmission using the beam. Numerous other aspects are provided.

Beam determination prior to beam activation indication

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.

Receiver adjustment for wireless communication

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).

Power control scheme for active bandwidth part transition

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.

Dynamic UE beam switching for mmWave measurements in asynchronous networks

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.

Techniques for thermal mitigation and power saving

Methods, systems, computer-readable media, and apparatuses for to managing use of a satellite positions system (SPS) receiver in conjunction with one or more radio access technology (RAT) transmitters. In certain embodiments, a controller can be used to prioritize reception by the SPS receiver over transmission by the one or more RAT transmitters.

Coexistence management of GNSS and wireless operations

Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Enhanced machine type communications quick idle transition after connection release

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.

Skipping periodic measurements to enable power saving in user equipments

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.
