Abstract: Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.

Abstract: Certain aspects of the present disclosure provide techniques for allocating a number of physical downlink control channel (PDCCH) blind decoding candidates to a user equipment (UE) in dual connectivity mode. An example method generally includes allocating a resource budget among a first cell group and a second cell group, wherein the resource budget includes a number of physical downlink control channel (PDCCH) blind decoding candidates and a number of control channel elements (CCEs) supported by the UE, and monitoring for PDCCH candidates in the first cell group and second cell group in accordance with the allocated resource budget.

Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH around NZP CSI RS transmissions in multi-TRP scenarios. In some cases, a network entity may signal a rate matching behavior to a user equipment (UE) for processing a physical downlink shared channel (PDSCH) configured with a first quasi co-location association and transmitted from a first transmission reception point (TRP) that potentially collides with one or more types of non-zero power (NZP) reference signals (RS) configured with a second quasi co-location association and transmitted from a second TRP using one or more resource sets.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive an indication of a set of corresponding physical downlink control channel (PDCCH) candidates that includes at least a first PDCCH candidate included in a first control resource set (CORESET) and a corresponding second PDCCH candidate included in a second CORESET, wherein the first CORESET and the second CORESET have different transmission configuration indication (TCI) states; and selectively perform, based at least in part on a configuration, at least one of: independent decoding of the first PDCCH candidate, independent decoding of the second PDCCH candidate, or joint decoding of the first PDCCH candidate and the second PDCCH candidate. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes a physical downlink control channel (PDCCH) monitoring adaptation field indicating to skip PDCCH monitoring for a duration on an active downlink bandwidth part (BWP) of a serving cell. The UE may transmit a NACK, in accordance with a feedback mode, based at least in part on an incorrectly decoded physical downlink shared channel (PDSCH) transmission. The UE may perform, based at least in part on the NACK, PDCCH monitoring for PDCCH candidates carrying groupcast scheduling DCIs. The UE may skip, based at least in part on the NACK, PDCCH monitoring for PDCCH candidates carrying unicast scheduling DCIs. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may monitor search space sets (SSSs) associated with a first SSS group (SSSG) for at least one control channel. The UE may switch from the first SSSG to a second SSSG based on an occurrence of an event. The UE may monitor SSSs associated with a second SSSG for the at least one control channel.

Abstract: Certain aspects of the present disclosure provide techniques for configuring for communications on noncontiguous carriers of a single cell. By combining multiple noncontiguous carriers into a single cell, broadcast overhead can be reduced and cell management (i.e., only one cell) can be simplified. For example, a network entity may transmit to a user equipment (UE) configuration information that configures the UE for communications on noncontiguous carriers of a single cell. The network entity and the UE may then communicate on the noncontiguous carriers in accordance with the configuration information.
