Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information indicating a set of component carriers (CCs) associated with the UE. The UE may receive, from the base station, a message that activates or deactivates one or more CCs of the set of CCs. The UE may communicate, with the base station, after receiving the message, using one or more activated CCs of the set of CCs over a tuned radio frequency (RF) bandwidth that is based on receiving the message and based on the one or more activated CCs. Numerous other aspects are provided.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications at a user equipment (UE) for measuring one or more synchronization signal block (SSB) beams from a network entity; selecting a highest rated SSB beam from the one or more SSB beams based on one or more selection factors; transmitting, to the network entity, a beam report including an identification of the highest rated SSB beam; initiating a timer in response to transmitting the beam report; determining whether a media access control (MAC) control element (CE) is received from the network entity before expiration of the timer; and performing beam switching from a current SSB beam to the highest rated SSB beam based on a determination that the MAC CE is not received from the network entity before expiration of the timer.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, based at least in part on two or more measurements on a channel taken at different points in time, that the channel is classified as static. The wireless communication device may perform at least one optimization based at least in part on determining that the channel is classified as static. For example, the at least one optimization may include modifying a channel state feedback procedure, reducing a periodicity associated with a measurement gap, modifying a filtering associated with measurements of the channel, reducing a threshold associated with beam switching, and/or refraining from performing at least one filtering at a radio frequency receiver of the wireless communication device. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for adapting search, measurement, and loop tracking periodicities in new radio communications. A method that may be performed by a user equipment (UE) includes determining, based on one or more parameters, a first periodicity to perform a search to detect one or more component carriers (CCs), cells, beams, or a combination thereof; a second periodicity to perform measurement of one or more cells, beams, or both in one more detected CCs; and a third periodicity to perform loop tracking to monitor a downlink serving quality, an uplink serving beam quality, or both of a cell. The method may further includes performing the search at the determined first periodicity, measurement at the determined second periodicity, and loop tracking at the determined third periodicity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may measure a beam, according to a measurement configuration, to determine a channel condition value of the beam, modify the channel condition value based at least in part on at least one of one or more beam characterizations, a derivation of a beamforming gain value, or an estimation of the beamforming gain value, and transmit, to a base station, a measurement report indicating the modified channel condition value. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.

Abstract: Aspects of the present disclosure provide a plurality of discovery reference signal (DRS) search modes implemented by the user equipment (UE) during contention-based communication in an unlicensed spectrum. The plurality of DRS search modes may include a first DRS search mode (“Full search mode”), second DRS search mode (“Comb search mode”), and a third DRS search mode (“Thin search mode”). The DRS search modes may be selected by the UE based on the system requirements (e.g., tradeoffs between robustness and complexity against cycle cost). Features of the present disclosure further provide techniques for dynamically switching between the plurality of DRS search modes in order to minimize power consumption while reducing the number of cycles required to locate the DRS.

Abstract: Certain aspects of the present disclosure relate to techniques for estimating a channel using soft-windowing. A user equipment (UE) may determine, based on a cyclic prefix (CP) length of a channel, a timing window for sampling reference signals transmitted on the channel, determine a set of weights to apply to samples obtained within the determined timing window, wherein each weight corresponds to a sample obtained within the determined window, and estimate the channel by applying the weights to the samples.
