Abstract: Various aspects of the disclosure relate to use of a default communication configuration for cross carrier wireless communication. For example, a wireless communication device such as a user equipment (UE) may use a default communication configuration that includes quasi-colocation information (e.g., a default CORESET configuration) for communication on a secondary component carrier (SCC). The default communication configuration may be used, for example, in scenarios where a CORESET is not defined for the SCC and other configuration information is not available. For example, other configuration information might not be available due to a short time gap between a grant sent on a primary component carrier (PCC) and the communication on the SCC scheduled by the grant.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally receiving pre-configuration information for one or more reference signal transmissions, performing, at a first time during an ON duration of a discontinuous reception (DRX) cycle, measurements on one or more reference signals based, at least in part, on the pre-configuration information, determining if, at a second time during the ON duration after the first time, a trigger frame associated with the one or more reference signal transmissions has been received, and transmitting a measurement report corresponding to the measurements if a trigger frame has been received.

Abstract: Certain aspects of the present disclosure provide techniques for reducing inter-sector interference. A method generally includes transmitting, in a multi-user multiple-input and multiple-output (MU-MIMO) mode, first beamformed transmissions using a first beam to a first user equipment (UE) in a first sector and second beamformed transmissions using a second beam to a second UE in a second sector, wherein the BS is configured to control a plurality of sectors comprising the first sector and the second sector, receiving, from the first UE, a feedback report indicating inter-sector interference encountered by the first UE in the first sector due to the second beamformed transmissions, and taking one or more actions based on the feedback report to reduce the inter-sector interference encountered by the first UE in the first sector.

Abstract: A method, apparatus, and computer program product for wireless communication are provided in which a transmission power is prioritized between an access channel and a second channel. Additionally, the access channel and the second channel are transmitted simultaneously. Each of the access channel and the second channel are transmitted at a transmission power determined based on the priority.

Abstract: Aspects described herein relate to determining, based on a received signal strength, a set of potential backhaul nodes for providing a backhaul link in an integrated access and backhaul (IAB) network, determining, based at least in part on additional information regarding the set of potential backhaul nodes, at least one backhaul node of the set of potential backhaul nodes to which to connect over the backhaul link in the IAB network, and indicating, to an access node, the at least one backhaul node for attempting connection over the backhaul link.

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: In an embodiment, a network entity schedules, as part of a positioning procedure for a UE, a first set of resources for transmission of DL RS(s) by at least one BS to the UE. The network entity associates the DL RS(s) with UL RS(s) for transmission by the UE on a second set of resources to one or more BSs as part of the positioning procedure for the UE. The network entity transmits, to the UE, an indication of the association between the DL RS(s) and the UL RS(s). The UE receives the indication along with the DL RS(s) from the at least one BS. The UE transmits the UL RS(s) to the one or more BSs on the second set of resources in response to the received indication.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include a UE determining a priority of a UE quality of service over UE thermal efficiency constraints, generating a priority indicator based at least in part on the determined UE quality of service priority, and transmitting to a base station via physical layer signaling, the priority indicator. Another method may include a UE determining a priority of a UE quality of service over UE energy constraints, generating a priority indicator based at least in part on the determined UE quality of service priority, and transmitting to a base station via physical layer signaling, the priority indicator. Yet another method may include a base station receiving a UE priority indicator specifying a UE quality of service priority over thermal efficiency constraints and temporarily prioritizing the UE QoS over UE thermal efficiency constraints based on the received priority indicator.
