There is provided, an open radio access network distributed unit (O-DU) having an electronic module that performs an FS-8 Radio Access Technology (RAT) functionality.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives an indication of a number of slots in a slot group. The UE receives a configuration associated with a duration indicating a number of slot groups in which down link control channels are to be monitored by the UE. The UE receives an indication indicating one or more slots, in each slot group in the duration, in which search spaces are located for detecting the down link control channels. The UE searches the search spaces in the one or more slots in each slot group in the duration to detect the down link control channels.

Methods, systems, and devices for wireless communication are described. A first wireless device may establish a sidelink communications link with a second wireless device. The first wireless device may transmit, to the second wireless device, an indication of a capability to support a configuration for phase continuity between multiple physical channel transmissions of the sidelink communication link. The first wireless device may transmit one or more physical channel transmissions, which each may be associated with a set of one or more demodulation reference signals (DMRSs) to the second wireless device in accordance with the indicated configuration for phase continuity between the physical channel transmissions. The second wireless device may determine channel parameters associated with the one or more physical channel transmissions based on a joint channel estimation associated with the one or more sets of DMRSs.

A method and device are disclosed for radio resource allocation to support User Equipment-to-Network (UE-to-Network) relaying. The network node establishes a Radio Resource Control (RRC) connection with a remote UE via a relay UE. The network node transmits a first RRC message to the remote UE via the relay UE, wherein the first RRC message includes a Uu radio bearer configuration and a Sidelink (SL) Radio Link Control (RLC) bearer configuration associated with a data radio bearer (DRB) or a signalling radio bearer (SRB) and wherein the network node is allowed to include a first field used to indicate a configuration for UE autonomous resource selection for sidelink communication transmission in the first RRC message and the network node is not allowed to include a second field used to indicate a configuration for UE to transmit sidelink communication based on network scheduling in the first RRC message.

The present disclosure provides a method and device in a node for wireless communications. A first node determines a first resource set and a first resource set group out of M resource sets; monitors a first-type channel in the first resource set group in a first time window. Any two of the M resource sets are overlapped in time domain, and the first resource set group comprises the first resource set; any of the M resource sets is connected to one or two spatial states; a reference resource set is any of the M resource sets different from the first resource set; whether the reference resource set satisfies a first condition is used to determine whether the reference resource set belongs to the first resource set group. The above method avoids the performance loss incurred by UE's unnecessary dropping the monitoring on some PDCCH candidates.

A method related to physical uplink control channel (PUCCH) cell switching and a user equipment (UE) are provided. The method includes: receiving a radio resource control (RRC) message from a base station; determining a PUCCH cell from the first cell and the second cell according to at least one PUCCH cell pattern; and transmitting the PUCCH transmission on the PUCCH cell during the time resource units. The RRC message includes at least one PUCCH cell pattern associated with multiple cell indexes and a first subcarrier spacing (SCS) associated with a first cell and a second SCS associated with a second cell. Each cell index corresponds to a cell, and the PUCCH cell pattern indicates which cell corresponds to one time resource unit used for PUCCH transmission.

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, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a cross-component carrier or cross-beam quasi co-location (QCL) configuration in a sidelink carrier aggregation configuration. For example, a first beam on a first component carrier may be QCLed with a second beam on a second component carrier. The first beam may have a different beam width than the second beam or be in a different frequency range than the first beam, or both. If an application at the UE requests the UE to configure a beam on the second component carrier, the UE may use some parameters used to receive on the first component carrier to communicate using the second beam on the second component carrier.
