Abstract: The base station may transmit a mode switch indication to a UE to switch from a first duplex mode to a second duplex mode. The UE may activate or deactivate one or more antenna panels and the UE and the base station may communicate with each other based on the mode switch indication. The second duplex mode may be FD mode, and the mode switch indication may be transmitted a threshold number of symbols or slots prior to the FD symbols. The slot format pattern may not include FD symbol, and the base station and the UE may communicate bidirectional signals in FD mode using the flexible symbols. The second duplex mode may be HD mode. The slot format pattern may include the FD symbols, and the base station and the UE may transmit or receive signals in HD mode using the FD symbols as the flexible symbols.

Abstract: A UE may receive, from a base station, a configuration for a plurality of parameter sets that each include one or more parameters for a RACH message and are each associated with one of TDM, FDM, or SDM. The UE may determine a transmission type of the RACH message corresponding to one or more of the TDM, the FDM, or the SDM and transmit the RACH message to the base station based on at least one parameter set and the determined transmission type of the RACH message. In aspects, the configuration received by the UE may be a configuration for transmitting the RACH message based on a RACH determination protocol. The UE may transmit the RACH message to the base station based on the received configuration associated with the RACH determination protocol and the determined at least one transmission type of the RACH message.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may manage a shape of a beam to selectively reduce interference at one or more wireless nodes. The base station may receive a capability message from a first wireless node indicating a capability of the first wireless node to support one or more beam tapering configurations. In some cases, the base station may receive an interference report from a second wireless node, indicating that the first wireless node caused interference at the second wireless node. The base station may transmit a beam tapering configuration of the one or more beam tapering configurations to the first wireless node, and the first wireless node may transmit a beamformed message to the base station according to the beam tapering configuration. In some cases, the beam tapering configuration may be associated with less interference when transmitting the beamformed message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, for full-duplex mode communication on a first link and a second link, a timing adjustment to at least one of a first timing or a second timing, wherein the timing adjustment is to cause a delay between clutter reflection from a first signal and an occurrence of a second signal to occur during a cyclic prefix of the second signal; cause the timing adjustment to be applied to the at least one of the first timing or the second timing; and communicate in the full-duplex mode with a first node and a second node in accordance with the timing adjustment, wherein communicating includes transmitting the first signal to the first node and receiving the second signal from the second node. Numerous other aspects are provided.

Abstract: A wireless node in a wireless multi-hop network may transmit, based at least in part on a change in multiplexing capability relating to communications on one or more radio link control (RLC) channels, information to at least one of a parent node or a child node that enables the at least one of the parent node or the child node to prioritize communications with the wireless node. The wireless node may transmit or receive communications prioritized according to the information with the at least one of the parent node or the child node.

Abstract: A UE may receive, from a base station/TRP, a configuration for a beam pair including an UL beam and a DL beam and transmit a RACH message via the UL beam while receiving DL information via the DL beam. The UE and/or the base station/TRP may be configured to operate in a FD mode. In aspects, the UE may transmit a RACH preamble based on a first mode of transmission. After a threshold time delay measured from the transmission of the RACH preamble, the UE may retransmit the RACH preamble based on a second mode of transmission. The second mode of transmission may be a same mode of transmission or a different mode of transmission from the first mode of transmission. Each mode of transmission may be based on one or more of TDM, FDM, or SDM.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, via a mobile termination (MT) and from a central unit (CU) of a donor network node, a first message that includes first information associated with a token. The network node may transmit, via a distributed unit (DU) and to the CU of the donor network node, a second message that includes second information associated with the token, to thereby indicate collocation of the MT and the DU. Numerous other aspects are provided.

Abstract: When moving within an area covered by an Integrated access and backhaul (IAB) network, a mobile IAB node may come into proximity with another stationary or mobile IAB node that may have a same physical cell identifier (PCI) as the mobile IAB node. PCI collision issue may occur. Aspects presented herein address the possible PCI collisions. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an IAB node configured to determine a configuration associated with PCI management of a PCI of the IAB node. The apparatus may be further configured to change the PCI of the IAB node based on the determined configuration.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first communication device may receive, from a second communication device, control signaling triggering a channel access procedure at the first communication device. In some case, the channel access procedure may be for accessing the shared radio frequency spectrum. The first communication device may then perform the channel access procedure based on the control signaling. In some examples, the first communication device may, based on the channel access procedure, transmit an indication of a channel occupancy initiated by the first communication device to the second communication device. The first communication device may relay communications between the second communication device and a third communication device during a channel occupancy time (COT) based on the transmitted indication of the channel occupancy initiated by the first communication device.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance functionality of directional repeaters (for instance, wireless devices that relay directional wireless signals). By adding even limited capability within the directional repeaters to buffer digital samples, the functionality of the directional repeaters may be enhanced to provide better coverage and make more efficient use of time, frequency, and spatial resources.
