Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may allocate, from an energy of the UE, a first amount of energy to a first communication link and a second amount of energy to a second communication link. The UE may identify a first energy request associated with the first communication link of the UE and a second energy request associated with the second communication link of the UE. The UE may allocate, from a remainder of the energy after the first amount of energy and the second amount of energy are allocated, a third amount of energy to the first communication link and a fourth amount of energy to the second communication link. The UE may transmit in accordance with the third amount of energy or the fourth amount of energy. Numerous other aspects are described.

Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may identify one or more candidate beams that have a better channel metric than a serving beam. The UE may initiate a beam switch measurement counter, and perform one or more measurements on the identified candidate beams. In the event that one of the candidate beams is better than the serving beam for each measurement of the one or more measurements, the UE may perform a beam switch procedure to switch from the serving beam to the candidate beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a cell search using a first set of beams. The UE may determine a channel condition value based at least in part on performing the cell search. The UE may modify the channel condition value based at least in part on at least one of: the first set of beams used to perform the cell search, a beam selected from the first set of beams, or a second set of beams that is different from the first set of beams and that is included in a beamforming codebook associated with the UE. The UE may transmit a measurement report that includes the modified channel condition value. Numerous other aspects are provided.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for applying a zero element beam to conserve power in search and measurement operations of a UE. The UE may determine to measure a set of SSBs, where each SSB of the set of SSBs is transmitted on four symbols, and further determine a subset of the SSBs for which less than the four symbols associated with the SSBs are to be used for measurement of the SSBs. The UE may measure each SSB of the subset of the SSBs through less than the four symbols associated with the SSB.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for selecting a PRACH occasion (RO) based on downlink quality, access congestion, latency (e.g., time to next available RO), beam correspondence, random access in previous transmissions, or combinations of these factors. The user equipment (UE) may detect access congestion of synchronization signal blocks (SSBs) and select the less congested SSB in the RO selection. The UE may detect the access congestion by receiving a back-off indicator from the base station, detecting a contention resolution failure, or the number or media access control (MAC) subheaders in a random access response. In some cases, the ROs associated with different SSBs have different latencies and the UE may select the earliest available RO.

Abstract: Aspects of the disclosure relate to devices, systems and methods for multi-beam formation. A user equipment (UE) may determine a sampling interval for references signals to be transmitted by a base station for an upcoming control or data communication. For example, the UE may determine a maximum sampling interval tolerable for channel estimation and select the sampling interval based on the maximum. In some examples, the UE determines the sampling interval based on characteristics of its motion. The UE transmits an indication of the sampling interval to the base station. Based on the indication, the base station selects an interval for the reference signals and transmits the reference signals to the UE to enable it to perform the channel estimation for the multi-beam. The base station may determine to select the interval for the reference signals such that it is less than or equal to the sampling interval indicated by the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first set of synchronization signal blocks (SSBs) for a first subscription of the UE and a second set of SSBs for a second subscription of the UE; select a first SSB, from the first set of SSBs, for communications of the first subscription; identify a third set of SSBs by modifying the second set of SSBs to remove one or more SSBs from the second set of SSBs, at least one SSB of the one or more SSBs overlapping in time with the first SSB; select a second SSB from the third set of SSBs; and monitor the second SSB for paging messages of the second subscription. Numerous other aspects are provided.

Abstract: Sensor assisted beam management system and methods for mobile User Equipment (UEs) are disclosed. An embedded rotation sensor may be used to determine orientation, rotating direction and angular speed of the UE. A speed sensor and GPS may also be used to determine location, moving direction and speed of the UE. The sensor outputs may be used by the UE to efficiently select UE beams after movement or to predict when a UE beam should be updated. Beam search and measurement periodicities may also be updated based on UE movements reported by the sensors.

Abstract: Methods, systems, and devices for wireless communication are described. For a user equipment with a number of M greater than or equal to two antennas, a signal is transmitted from at least a first antenna and a second antenna at a first time with an initial relative phase state including a first relative phase rotation between the signals transmitted by the first and second antennas. In response to a determination that a response signal was not received at the user equipment, the signal is retransmitted from at least the first antenna and the second antenna with a subsequent relative phase state among the transmitting antennas, including a second different relative phase rotation, at a second time. The second time may be the next subsequent retransmission of the signal or may be a retransmission following one or more retransmissions using the first relative phase rotation.
