Abstract: Systems, devices, and methods for performing coordinated clear channel assessments (CCAs) in a shared radiofrequency band are provided. In one aspect, a method of wireless communication performed by a first wireless communication device includes: receiving a control signal indicating a CCA trigger associated with the first wireless communication device and a second wireless communication device; performing, based on the CCA trigger, a CCA; transmitting, to the second wireless communication device based on the CCA, a first CCA success signal; receiving, from the second wireless communication device, a second CCA success signal; initiating, based on the first CCA success signal and the second CCA success signal, a channel occupancy time (COT); and amplifying and forwarding a communication in the COT.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first user equipment (UE) may identify a configuration for an assisting node (AN) that includes an indication of a set of time resources during which the AN is active and an indication of location information that indicates communication direction information corresponding to communications via the AN during the set of time resources. The first UE may select a time resource from the set of time resources based on the indication of location information, a location of the first UE, and information associated with a packet for transmission from the first UE to a second UE via the assisting node. The first UE may transmit the packet over the selected time resource.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for dynamically activating and deactivating random-access channel (RACH) occasions (ROs). A base station may configure one or more ROs on which a user equipment (UE) can transmit RACH messages. If higher priority signaling (e.g., downlink signaling or uplink signaling) overlaps in time with the ROs, the base station may deactivate one or more ROs to decrease the likelihood of self-interference or cross-link interference (e.g., if the UE or the base station are operating in full duplex mode). The base station may deactivate or activate ROs by indicating indices for one or more ROs, indices for one or more synchronization signal blocks (SSBs), a pattern of ROs, some or all ROs within a time period, some or all ROs until a next downlink signal updates the RO configuration or activates ROs, or any combination thereof.

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: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater that relays communications between communication devices. The repeater determines a downlink gain value to use for one or more downlink initial access messages received at the repeater. The repeater determines an uplink gain value to use for one or more downlink initial access messages received at the repeater. The uplink gain value is based on the downlink gain value and a noise level related to a channel between the communication device and the repeater. The repeater receives a downlink initial access message, and applies the downlink gain value to the downlink initial access message. The repeater receives an uplink initial access message, and applies the uplink gain value to the uplink initial access message.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device such as a user equipment (UE) may determine to transition from a first duplexing mode to a second duplexing mode, where a first communication associated with the first duplexing mode at least partially overlaps in time with a second communication associated with the second duplexing mode. Based on the overlap, the UE may identify transition information for coordinating the transition between the first duplexing mode and the second duplexing mode. Using the transition information, the UE may transition from the first duplexing mode to the second duplexing mode, and may communicate with a second wireless device, such as a base station, using the second duplexing mode.

Abstract: Wireless communications systems and methods related to sharing channel occupancy time (COT) for a channel in an unlicensed 5G spectrum in an integrated access backhaul (IAB) network are provided. In some aspects, an IAB node of the IAB network may perform a channel access procedure to acquire the COT and share the COT with a parent IAB node and/or a child IAB node for the parent IAB node and/or child IAB node to communicate back with the COT initiating IAB node. The sharing of the COT with the parent IAB node and/or child IAB node may also include a sharing of the same COT between a distributed unit and a mobile terminal of the COT-initiating IAB node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a parent node may determine that a set of resources is not available for the parent node for communication with a child node of the parent node. The parent node may provide an availability indicator to the child node based at least in part on determining that the set of resources is not available for the parent node for communication with the child node. The availability indicator may indicate the set of resources as available for the child node. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may be scheduled by a base station for full-duplex sidelink transmissions. A first UE may receive, from a base station, a first sidelink grant indicating a first set of resources and a second set of resources. The first set of resources may at least partially overlap in time with the second set of resources. Upon receiving the first sidelink, the first UE may transmit, to a second wireless device, a second sidelink grant indicating the second set of resources. The first UE may transmit a first data message to the second UE over the first set of resources and receive a second data message from the second device over the second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine to operate in accordance with an energy saving mode in which the base station only transmits remaining minimum system information (RMSI) on-demand or reduces transmission of RMSI with respect to when the base station is operating outside of the energy saving mode. A user equipment (UE) may detect the base station that is operating in an energy saving mode. The UE may transmit a request for the base station to transmit the RMSI to the UE, where the UE may transmit the request to the energy saving base station or to a serving base station of the UE. The UE may receive, from the base station operating in the energy saving mode and responsive to the request, a message including the remaining minimum system information.
