Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a base station may transmit an indication of a communications mode capability associated with establishing a connection with the base station, and a user equipment (UE) may establish a connection with the base station if the UE has the communications mode capability. In this aspect, the base station may bar UEs that lack the communications mode capability from establishing a connection with the base station such that the base station may avoid configuring or scheduling communications differently for devices with different capabilities. In another aspect, a base station may transmit an indication of whether the base station operates in a full-duplex mode, a half-duplex mode, or both, and a UE may establish a connection with the base station based on whether the base station operates in the full-duplex mode, the half-duplex mode, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating an uplink gap. The UE may transmit a reference signal in the uplink gap. The UE may perform at least one of a self-interference measurement or a beam pair calibration for full-duplex communication based at least in part on the reference signal. Numerous other aspects are described.

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: 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: 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 user equipment (UE) may receive one or more messages scheduling resources allocated for one or more uplink transmissions that at least partially overlap in time with scheduled resources allocated for one or more downlink transmissions. In such cases, the UE may use different communication parameters for overlapping and non-overlapping resources. For example, the UE may receive a configuration of a first set of communication parameters that are configured for an overlapping portion of the resources and a second set of communication parameters that are configured for a non-overlapping portion of the resources. The UE may apply the first set of communication parameters and the second set of communication parameters to the uplink and downlink resources for transmitting or receiving the one or more uplink and downlink communications.

Abstract: Aspects relate to Layer 1/Layer 2-centric inter-cell mobility communication systems where measurement information from at least one user equipment (UE) is sent to a base station. Based on this information, the base station may select at least one of a remote radio head (RRH), a serving cell, or a cell assigned with a physical cell ID that serves a particular UE using one of Layer 1 or Layer 2 control signaling based on the received measurement information and a system serving cell configuration or mode of operation. Additionally, an indication may be provided of whether cell configurations are the same for target and source cells in an inter-cell handover and a UE may utilize the same source cell configuration during a handover when connecting with the target cell when the configurations match or at least partially match.

Abstract: Aspects of the disclosure relate to a method for wireless communication at a user equipment (UE). In some aspects, the UE receives, from a base station, configuration information for performing beam pair selection measurements with respect to a subset of candidate beams at the UE. The beam pair selection measurements may include at least self-interference measurements at the UE between one or more transmit (Tx) beams and one or more receive (Rx) beams in the subset of candidate beams. The configuration information indicates measurement gaps between the self-interference measurements. The UE performs the beam pair selection measurements based on the configuration information and selects at least one pair of Tx/Rx beams based on the performed beam pair selection measurements. The UE transmits a report including the selected at least one pair of Tx/Rx beams to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a control node, an indication of a capability of the first wireless node to perform one or more self-interference cancelation (SIC) procedures between a first antenna array of the first wireless node and a second antenna array of the first wireless node. The first wireless node may receive, from the control node in response to the indication of the capability, a configuration for the first wireless node to use to perform a SIC procedure of the one or more SIC procedures for full-duplex communications. The first wireless node may then communicate, according to the received configuration, with the control node, a control node, or any combination thereof, using the first antenna array and the second antenna array.
