A resource determining method, a resource indication method, and a device are provided. The resource determination method is performed by a user side device, including: obtaining time domain resource indication information of downlink control information (DCI), where the time domain resource indication information supports scheduling of multiple carriers or bandwidth parts (BWPs); and determining a scheduling time domain resource on the multiple carriers or BWPs according to the time domain resource indication information.

A method for transmitting automatic repeat request acknowledgement feedback information supporting a multicast service and an apparatus are provided. The method includes: receiving N pieces of first downlink control information (DCI) and M pieces of second DCI in at least one first time unit, where the first DCI is a first-type DCI, the second DCI is a second-type DCI. Each piece of first DCI includes a first downlink assignment index (DAI), and the first DAI includes a first counter downlink assignment index (C-DAI) that indicates an accumulative quantity of pieces of first-type DCI for scheduling transmission of a downlink data channel. Each piece of second DCI includes a second DAI, and the second DAI includes a second C-DAI that indicates an accumulative quantity of pieces of second-type DCI for scheduling transmission of a downlink data channel.

Disclosed are techniques for wireless communication. In an aspect, a position estimation entity provides assistance data to sidelink anchors and a UE. The assistance data may include a set of proximity-based sidelink positioning reference signal (PRS) pre-configurations for on-demand PRS position estimation. The target UE transmits a sidelink PRS trigger to trigger an on-demand sidelink PRS position estimation session with a dynamic sidelink anchor group, the sidelink PRS trigger configured to indicate a sidelink zone associated with the UE and a proximity requirement for participation in the on-demand sidelink PRS position estimation. At least one sidelink anchor determines that the proximity requirement to the sidelink zone is satisfied, selects a proximity-based sidelink PRS pre-configuration based on a dynamic proximity to the sidelink zone, and performs a sidelink PRS exchange with the UE.

Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).

A method of providing positioning reference signal information includes: transmitting wirelessly, from an apparatus, a positioning reference signal comprising a carrier signal with a carrier phase; and transmitting, from the apparatus, an indication of a reference carrier phase of the positioning reference signal, comprising a phase of the carrier signal of the positioning reference signal at a reference time of transmission of the positioning reference signal.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. In certain configurations, the UE receives DCI scheduling two or more downlink data channels to be transmitted in one or more slots. The UE determines an indication, in the DCI, indicating a first TCI state and a second TCI state. The UE receives each of the two or more downlink data channels in a respective first set of resources in accordance with the first TCI state and in a respective second set of resources in accordance with the second TCI state.

A method for a user equipment (UE) of determining a tracking reference signal (TRS) resource set availability is provided. The method includes receiving, from a base station (BS), a TRS configuration that indicates one or more TRS resource sets for the UE to monitor reference signals; determining whether a Layer 1 (L1)-based availability indication for the one or more TRS resource sets is received from the BS; and determining the one or more TRS resource sets are unavailable when the UE determines that the L1-based availability indication has not been received from the BS.

A method by a UE for handling PDSCH reception includes receiving, from a BS, a first PDSCH configuration in a CFR configuration for a multicast PDSCH, a second PDSCH configuration in a BWP configuration for a unicast PDSCH, and first DCI scheduling the multicast PDSCH, the first PDSCH configuration including a first aperiodic resource set configuration, the second PDSCH configuration including a resource configuration and a second aperiodic resource set configuration, the resource configuration for configuring one or more ZP CSI-RS resources, and the first DCI including a first field for triggering a first aperiodic ZP CSI-RS; and determining, based on the first field, a first ZP CSI-RS resource set, which is not available for reception of the multicast PDSCH, from a first list of ZP CSI-RS resource sets configured by the first aperiodic resource set configuration. The resource configuration is absent in the first PDSCH configuration.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, an indication of a physical downlink control channel (PDCCH) processing unit (PPU) limit associated with the UE. The UE may receive configurations for a plurality of search space sets, wherein the plurality of search space sets includes one or more linked pairs of search space sets with linked PDCCH candidates for PDCCH repetition. The configurations of the one or more linked pairs of search space sets may be based at least in part on the PPU limit associated with the UE. Numerous other aspects are described.

Methods and apparatuses for transmission configuration indication (TCI) state indication for control channels in a wireless communication system. A method of operating a user equipment (UE) includes receiving downlink control information (DCI) including at least one TCI codepoint indicating first and second TCI states and receiving an indicator to indicate the first or second TCI state to use for determining a quasi co-location (QCL) assumption for receiving a first physical downlink control channel (PDCCH). The method further includes determining, based on the indicator, the first or second TCI state to use for determining the QCL assumption; determining, based on the determined first or second TCI state, the QCL assumption for receiving the first PDCCH; and receiving, based on the determined QCL assumption, the first PDCCH in a first control resource set (CORESET).
