The present disclosure relates to methods and apparatuses. According to some embodiments of the disclosure, a method includes: receiving Downlink Control Information (DCI) in a first Control Resource Set (CORESET), wherein the DCI schedules a Physical Uplink Shared Channel (PUSCH) and the first CORESET is configured with a first pool index; and transmitting the PUSCH scheduled by the DCI according to a pathloss reference Reference Signal (RS) based on the first pool index.

Various aspects of the present disclosure generally relate to multi-slot transmission time interval based channel state information (CSI) and uplink shared channel (UL-SCH) multiplexing. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message and determine, based at least in part on the DCI message, a schedule for multiplexing UL-SCH data and one or more components of uplink control information (UCI) in a plurality of slots on a physical uplink shared channel (PUSCH). The components may include a CSI report for a plurality of transmission reception points. The UE may multiplex the UL-SCH data and the one or more components into the plurality of slots based at least in part on the schedule. Numerous other aspects are provided.

A transmission acknowledgment method, a terminal device, and a transmission node are provided. The transmission acknowledgment method is performed by a first terminal. The method includes: monitoring a first physical control channel based on monitoring configuration information of the first physical control channel; obtaining first control information transmitted by a transmission node on the first physical control channel, where the first control information includes RTS information for a plurality of target terminal devices, and the plurality of target terminal devices include the first terminal; and sending CTS information on a second physical control channel based on the RTS information.

A maximum PDCCH processing capability allocation method includes: obtaining cell configuration information, where the cell configuration information indicates a plurality of configured cells and scheduling information of the plurality of configured cells, the plurality of configured cells include a plurality of cells configured for the terminal device for carrier aggregation, the scheduling information indicates that one first cell is scheduled by a plurality of first target cells, or the scheduling information indicates that one second cell schedules a plurality of second target cells at a time, and the first cell, the second cell, the first target cell, and the second target cell are cells in the plurality of configured cells; determining a total quantity of cells according to the cell configuration information; and allocating a maximum PDCCH processing capability of the terminal device based on the total quantity of cells and a maximum blind detection capability of the terminal device.

Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a control message in a first control channel occasion associated with a first quasi-colocation (QCL) property, the control message indicating a transmission of a data message within a threshold time period. The UE may receive, from the base station, an indication to skip monitoring of a second control channel occasion within the threshold time period and may receive the data message in accordance with a second QCL property, or drop reception of the data message, based on the indication. Additionally, or alternatively, the base station may transmit a message indicating a unified transmission configuration indicator (TCI) state associated with the second QCL property, and the UE may receive the data message in accordance with the second QCL property based on the unified TCI state.

An apparatus for wireless communication includes a transmitter configured to communicate with a base station based on a first uplink bandwidth part (BWP) that includes a first frequency subset and that further includes a second frequency subset. The apparatus further includes a receiver configured to receive, from the base station, one or more messages including a frequency hopping indicator that specifies whether a frequency hopping mode is enabled or disabled. The transmitter is further configured to transmit, to the base station, an uplink control channel transmission using both the first frequency subset and the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is enabled or using one of the first frequency subset or the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is disabled.

A wireless communication device for communicating across a wireless communication channel includes one or more processors configured to determine whether a further device is generating a radio frequency interference at an operating frequency; transmit a request message to the further device requesting the further device vacate the operating frequency based on the determination that the further device is generating radio frequency interference; receive a response message from the further device; and generate an instruction based on the response message.

Certain aspects of the present disclosure provide techniques for indicating carrier aggregation capabilities. An example method generally includes signaling, to a base station (BS), carrier aggregation capability information indicating a capability for performing separate operations concurrently on a plurality of component carriers; receiving a carrier aggregation configuration indicating component carriers designated for the separate operations; and receiving or transmitting transmissions based on the carrier aggregation configuration.

This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) with the capability to support a single active TCI state may receive configuration signaling which configures the UE with an active transmission configuration indication (TCI) state corresponding to a first beam for a control resource set and a shared data channel. The UE may perform a random access channel procedure to select a second beam from a set of different beams. The UE may update a quasi co-location (QCL) assumption for the control resource set to correspond to the second beam and deactivate the active TCI state based on updating the QCL assumption. The UE may then monitor the control resource set, the shared data channel, or both, using the second beam. The UE may deactivate the TCI state and use the indicated downlink beam so that the UE does not exceed its capability.
