Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment receives a sliding window of measurements associated with a radar signal transmitted by the UE; determines that a user is within a threshold distance of the UE, wherein the threshold distance is determined to be a first distance when an energy measurement, associated with the radar signal, indicates an energy reduction satisfying a threshold energy reduction, or wherein the threshold distance is determined to be a second distance when the sliding window of measurements indicates an amount of energy variation satisfying a threshold amount of energy variation associated with the radar signal; and performs, based at least in part on determining that the user is within the threshold distance, an action associated with a communication signal of the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method for wireless communications at a user equipment (UE) includes determining one or more performance metrics related to communications over a wireless channel and comparing the one or more performance metrics with a performance level for the communications over the wireless channel. The method may include selecting a power mode for the UE based at least in part on the comparing and determining an operating state of a subset of a plurality of radio frequency front end elements of at least one active radio frequency chain of the UE based at least in part on the power mode and a priority of the one or more performance metrics. The method may also include adjusting the subset of the plurality of radio frequency front end elements based at least in part on the operating state.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may utilize synchronization signal block (SSB) and channel state information reference signal (CSI-RS) based beam management to select beams for communicating with a base station. For example, a UE may receive, from a base station, control signaling that configures the UE to monitor a set of SSBs and a set of reference signals. The UE may select a subset of the set of SSBs based on measuring a first signal metric for each SSB of the set of SSBs. In some examples, the UE may select a reference signal subset of the set of reference signals that correspond to the subset of the set SSBs, and may communicate a data transmission with the base station using a first beam selected based on measuring a second signal metric for each reference signal in the reference signal subset.

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, a channel state information reference signal that includes a plurality of resource blocks. The UE may sub-sample one or more portions of the plurality of resource blocks prior to performing one or more channel state feedback computations. Accordingly, the UE may perform the one or more channel state feedback computations based at least in part on the one or more sub-sampled portions of the plurality of resource blocks and transmit, to the base station, a channel state feedback report based at least in part on the one or more channel state feedback computations that are performed using the one or more sub-sampled portions of the plurality of resource blocks. Numerous other aspects are provided.

Abstract: A device may selectively listen for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx) based on whether the device is to switch between repeaters of a base station (such as during travel). A device may determine whether the device is in a high speed train (HST) scenario (such as based on a difference in frequency errors generated using a synchronization signal block (SSB) and generated using a TRS, based on a trajectory of a frequency error or a frequency error difference over time, based on instantaneous frequency errors, etc.). When the device is in a HST scenario, the device listens for a TRS during CDRx, and the device generates a frequency error using the TRS. When the device is not in a HST scenario, the device prevents listening for a TRS during CDRx (with a SSB received during CDRx to be used to generate a frequency error).

Abstract: The apparatus may be a base station. The apparatus sets a first numerology for at least one synchronization signal of one or more synchronization signals to be different from a second numerology for at least one data signal of one or more data signals. The apparatus transmits the one or more synchronization signals to a user equipment (UE) based on the first numerology. The apparatus transmits the one or more data signals to the UE based on the second numerology.

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 disclosure relate to a wireless user equipment (UE) determining a wideband channel quality indicator (CQI) in a wireless communication network. For each of a plurality of CQI hypotheses, a UE divides a bandwidth into a plurality of frequency segments and determines an average spectral efficiency (SPEF) for each of those segments. Further, for each of the plurality of CQI hypotheses, the UE determines the minimum of the average SPEFs. The UE selects the CQI hypothesis corresponding to the maximum from among these determined minimum average SPEFs, and transmits this selected CQI as a wideband CQI. Other aspects, embodiments, and features are also claimed and described.
