Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for receiving, by a user equipment (UE) from a base station, a plurality of synchronization reference signals; measuring, by the UE, a respective Reference Signal Received Power (RSRP) value of each of the plurality synchronization reference signals; determining, by the UE, a highest RSRP value from each of the respective RSRP values; and calculating, by the UE, a downlink pathloss associated with a sidelink open loop power control based on the highest RSRP value.

Abstract: Certain aspects of the present disclosure provide techniques for control channel resource grouping and spatial relation configuration. Aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes receiving an indication of one or more groupings of one or more control channel resources within a configured bandwidth. Each grouping is associated with a spatial relation. The UE applies a spatial relation for a control channel transmission using one or more control channel resources in a grouping of the one or more groupings. The grouping is associated with the spatial relation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more candidate beams available for communication between the UE and a BS to replace another beam that is configured for communicating between the UE and the BS. The UE may transmit, based at least in part on identifying the one or more candidate beams, a communication that includes a new beam information (NBI) field and/or contents of the NBI field. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques to improve reliability and robustness for millimeter wave (mmW) systems in fifth generation (5G) wireless communications technology (also referred to as new radio (NR)). Specifically, the present disclosure provides techniques to allow the base station to group a plurality of mmW beams for communication with the user equipment (UE) such that the selected beam(s) for communication are independent and uncorrelated. The selection of beams ensure macro-diversity in that the joint blocking probability of the selected beam(s) may be minimized and the susceptibility to blockage is reduced in comparison to the current systems.

Abstract: The present disclosure relates to transmitting and receiving improved quality reports using different transmission states. A base station may transmit to a user equipment (UE) a channel comprising multiple beams, wherein the beams include different Transmission Configuration Indicator (TCI) states. The UE can then perform beam quality measurements for the multiple beams. The beam quality measurements can include different channel quality indicator (CQI) measurements and can be performed using the same or different spatial filters. The UE can then determine a combined beam quality report for the different beams and transmit the report to the base station. The beam quality report can also comprise a comparison of, the difference between, or the average of, the different CQI measurements. The UE can also receive a configuration of filtering coefficients from the base station, wherein the beam quality report comprises filtered CQI information.

Abstract: A transmitter, such as a base station, identifies a potential collision between a first set of resources configured for a CORESET for a receiver and a second set of resources configured for a PT-RS for the receiver. The apparatus may determine whether colliding resources in the CORESET are configured/used for a control transmission or a data transmission. The apparatus punctures the PT-RS based on whether the colliding resources in the CORESET are configured/used for the control transmission (e.g., PDCCH). For example, the apparatus may puncture the PT-RS only for resource blocks of the CORESET colliding with the control transmission without puncturing the PT-RS over an entire set of the colliding resources configured for the CORESET. A receiver may similarly identify potential collisions and determine whether PT-RS will be punctured based on whether the colliding resources in the CORESET are configured/used for a control transmission or a data transmission.

Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive transmission configuration indicator (TCI) activation information associated with identifying a set of carriers, wherein the set of carriers maps to a set of transmit receive point (TRP) mode values. The UE may communicate on a carrier, of the set of carriers, using a TCI state of the carrier, of one or more maintained TCI states of the carrier, and a communication configuration associated with a TRP mode of the carrier, the TRP mode being based at least in part on a TRP mode value, of the set of TRP mode values. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, a physical downlink control channel (PDCCH) order initiating a random access procedure in a candidate cell. The UE may determine a timing delay associated with a timing difference between the serving cell and the candidate cell. The UE may transmit a physical random access channel (PRACH) communication to the candidate cell in accordance with the PDCCH order and the timing delay. Numerous other aspects are described.
