摘要： Techniques and apparatus for beam selection in compliance with radio frequency (RF) exposure limits. A method that may be performed by a wireless device includes receiving, from another wireless device, a plurality of signals via a plurality of beams; measuring a received signal power for each of the beams, based on the received plurality of signals; determining a transmit power limit for each of the beams based at least in part on an RF exposure limit; determining an estimation of a signal quality at the other wireless device for each of the beams based at least in part the received signal powers and the transmit power limits; selecting one of the beams based on the estimations of the signal qualities for the beams; and transmitting a signal via the selected beam.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may allocate a first amount of power to one or more radios for a time window based on radio frequency (RF) exposure information and one or more other criteria. The UE may allocate a second amount of power to a selected channel or communication utilized by at least one radio of the one or more radios for one or more time frames within the time window based on the first amount of power allocated to the at least one radio for the time window. The UE may transmit the selected channel or communication based on the first amount of power or the second amount of power. Numerous other aspects are described.

摘要： Methods and systems for determining transmission power levels according to signal types and RF exposure limits. An example method generally includes determining a first transmission power for transmitting a first type of uplink (UL) signal, determining a second transmission power for transmitting a second type of UL signal based on the first transmission power, and transmitting at least one of the first UL signal according to the first transmission power or the second UL signal according to the second transmission power.

摘要： Certain aspects of the present disclosure relate to beam selection. An example method generally includes selecting, from a plurality of beams, a beam for uplink transmission during a particular time interval, the selecting being based on a transmission power and a radio frequency (RF) exposure for each of the plurality of beams and transmitting at least one uplink signal using the selected beam during the particular time interval.

摘要： Various aspects related to control channel (e.g., PSCCH) scheduling/prioritizing techniques in wireless communications are described. When a UE may not be able to decode various PSCCH transmissions detected in a subframe, a subset of the PSCCHs may be selected for decoding based on the described methods. In accordance with one aspect, a UE may determine that a total number of PSCCH transmissions in a subframe is greater than a number of PSCCH transmissions that can be decoded within the subframe. Upon such a determination, the UE may select at least one PSCCH transmission in the subframe for decoding based on at least one of: retransmission information, information regarding a transmitting UE associated with the at least one PSCCH transmission, or scheduling priority history associated with a sub-channel carrying the at least one PSCCH transmission. The UE may then decode the at least one PSCCH transmission selected for decoding.
