Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing transmit power control. In one aspect, a wireless device may receive a message including a path loss value and may transmit a signal to a UL Rx point using an uplink transmit power associated with the received path loss value. In another aspect, a wireless device may receive a reference signal, and a message including an offset value, and may transmit a signal to a UL Rx point using an uplink transmit power including a downlink path loss value associated with the reference signal minus the offset value. In another aspect, a base station may obtain a power measurement of a signal from a wireless device and may send to the wireless device a path loss value associated with the received power measurement, or an offset value associated with the received power measurement.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

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 including multiple transmission configuration indication (TCI) states associated with a control resource set (CORESET). The UE may receive, from the base station, a physical downlink control channel (PDCCH) in a region associated with the CORESET, wherein the PDCCH includes at least one control channel element (CCE). The UE may perform blind decoding for multiple configured PDCCH candidates based at least in part on a resource element group (REG) bundle included in the at least one CCE, wherein the multiple configured PDCCH candidates are associated with one or more of the multiple TC states associated with the CORESET. Accordingly, the UE may identify the PDCCH transmitted by the base station based at least in part on the blind decoding.

Abstract: Certain aspects of the present disclosure provide techniques for communicating using power control parameters for multiple transmitter receiver point (mTRP) physical uplink shared channel (PUSCH) repetition. A method that may be performed by a user equipment (UE) includes receiving a sounding reference signal (SRS) configuration indicating at least a first SRS resource set and at least a second SRS resource set, receiving downlink control information (DCI) scheduling a first set of one or more PUSCH repetitions to a first TRP and a second set of one or more PUSCH repetitions to a second TRP, and transmitting the first and second sets of PUSCH repetitions using at least one of a first set of default power control parameters or a second set of default power control parameters.

Abstract: Channel state information-reference signal (CSI-RS) resources are disclosed with multiple transmission configuration indication (TCI) states. Example aspects of the present disclosure provide for indications that a given CSI-RS resource is associated with multiple TCI states within various configuration control signaling, depending on whether the CSI-RS is periodic, semi-persistent, or aperiodic. Additionally, where any trigger state corresponds to a CSI-RS resource set in which one or more CSI-RS resources are associated with multiple TCI states, one or more quasi-co-location (QCL) assumptions of the downlink transmission may also be applied by a user equipment (UE) to reception of the CSI-RS resources, where the scheduling offset is less than the threshold beam switch timing reported by the UE.

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumption for an aperiodic channel state information (A-CSI) reference signal (RS) configured with multiple transmission reception point (mTRP). A user equipment (UE) may receive signaling configuring the UE with a plurality of index values associated with different control resource sets (CORESETS). The UE may receive, from a base station (BS), first downlink control information (DCI) triggering an A-CSI-RS resource set for A-CSI reporting. The first DCI is received in a first CORESET of the different CORESETs associated with a first index value of the plurality of index values. The UE may determine a first time offset between the first DCI and the A-CSI-RS resource set. When the first time offset is smaller than a threshold time offset, the UE may determine a QCL assumption for receiving the A-CSI-RS based, at least in part, on the first index value.

Abstract: Wireless communications systems and methods related to bandwidth part (BWP) switching after data communication are provided. A user equipment (UE) receives, from a base station (BS) in a first bandwidth part (BWP), one or more data bursts and BWP switching information. The UE switches from the first BWP to a second BWP based on the BWP switching information after receiving the one or more data bursts. The UE communicates, with the BS, a communication in the second BWP after the switching.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for demodulation reference signal (DMRS) and cell specific reference signal (CRS) collision avoidance procedures for wireless communication. Conventional networks and devices may be unable to perform DMRS shifting in some modes. For example, when considering two transmissions of multiple TRP modes, if a DMRS symbol for one transmission is shifted due to a collision with a CRS pattern, the alignment of the transmissions may be altered. If DMRS symbols of the transmissions are not aligned, interference or decoding failure may occur. The disclosure enables procedures for performing DMRS shifting in multiple TRP modes. For example, the DMRS symbols of both transmissions may be shifted responsive to determining an overlap for one transmission. Such shifting may enable the alignment of the DMRS locations for both transmissions to enable decoding of the transmissions.
