Abstract: Techniques are described herein that illustrate a feedback system to configure various format parameters of physical layer convergence procedure protocol data units (PPDUs) transmitted across a communication link. A receiving device may determine a Doppler shift or a delay spread of a signal received from a transmitting device. The receiving device may determine one or more format parameters for a future PPDU based on the Doppler shift or the delay spread. The receiving device may transmit an indication that includes the format parameters for the future PPDU to the transmitting device. The transmitting device may modify one or more format parameters of a PPDU based on the information in the indication. In some cases, the receiving device may indicate characteristics of mid-ambles, a type of PPDU, a guard interval, high efficiency long training field size for a future PPDU.

Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to a second UE, a SL BWP switching request message requesting a switch from a first BWP to a second BWP. The example method may further include receiving, from the second UE, an SL BWP switching decision message confirming the switch from the first BWP to the second BWP. The example method may further include switching from the first BWP to the second BWP upon receiving the SL BWP switching decision message. The example method may further include transmitting, to the second UE, an SL BWP switching confirmation message confirming the switch from the first BWP to the second BWP. The example method may further include reverting back to the first BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive transmission configuration indicator (TCI) information relating to a common beam TCI indication, the TCI information relating to a plurality of channels or reference signals. The UE may selectively transmit or receive one or more channels or reference signals of the plurality of channels or reference signals in accordance with the TCI information, based at least in part on whether the TCI information relating to the common beam TCI indication is usable for the one or more channels or reference signals of the plurality of channels or reference signals, wherein the one or more channels or reference signals are a proper subset of the plurality of channels or reference signals. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, in a full duplex communication mode, a channel measurement (CM) procedure associated with a self-interference measurement (SIM) procedure to determine a downlink signal to self-interference plus noise ratio associated with a downlink (DL) and uplink (UL) (DL/UL) beam pair of the UE; receive, from a base station, uplink interference information associated with a UL beam of the DL/UL beam pair of the UE, wherein the uplink interference information indicates at least one of: a final DL/UL beam pair selected by the base station; and transmit a measurement report based at least in part on the CM procedure and the SIM procedure, wherein the measurement report is based at least in part on the downlink signal to self-interference plus noise ratio.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., “victim” UE) may receive control signaling identifying a set of antenna panels of the first UE usable for measuring cross-link interference (CLI) experienced within a set of CLI resources. The first UE may perform CLI measurements on signals received from a second UE (e.g., “aggressor” UE) via the set of CLI resources and the set of antenna panels. The first UE may then transmit a CLI report associated with CLI measurements performed on the signals received via an antenna panel of the set of antenna panels. In some implementations, the CLI report includes an indication of the antenna panel, an indication one or more CLI resources from the set of CLI resources associated with the antenna panel, or a combination thereof.

Abstract: Systems and methods establishing and maintain a direct User Equipment to User Equipment communication link are disclosed. A User Equipment (UE) may receive a Sounding Reference Signal (SRS) from a neighboring UE. The UE may determine from the SRS that the UE is a good candidate for a direct link. The UE may also determine from the SRS an ID associated with the neighboring UE. The UE may send a direct link request to the UE serving gNB. The serving gNB may forward the request to a gNB serving the neighboring UE. The gNBs may negotiate a joint schedule for a beam a UE to UE beam search. The beam search may be conducted using SRS resources. The results of the beam search may be sent to the gNB and the gNB may determine a beam pair for a direct link.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an aggregation capability to communicate in parallel over a plurality of wireless links. The wireless device may in some cases broadcast this aggregation capability (e.g., periodically). Additionally or alternatively, the wireless device may transmit the aggregation capability in response to a request received from another wireless device. In some cases, the first wireless device may transmit a request to a second wireless device inquiring about aggregation capabilities of the second wireless device. The second wireless device may respond with its aggregation capabilities (e.g., or may broadcast its aggregation capabilities independently of receiving the response). The wireless devices may establish a multi-link session based at least in part on the indicated aggregation capabilities.

Abstract: A user equipment (UE) may receive, from at least one of a base station or a configuring UE, a configuration of a plurality of sidelink power control parameter sets, a media access control (MAC) control element (CE) (MAC-CE) activating transmission configuration indicator (TCI) states and indicating sidelink power control parameter sets, and control information indicating a TCI state and a sidelink power control parameter set. The UE may transmit the sidelink communication in a direction based on the TCI state and with a transmission power indicated in the control information. The MAC-CE may include a joint MAC-CE or separate MAC-CEs to update or configuration of the sidelink TCI and the power control parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a multi-slot downlink transmission, that a mapping from a transmission configuration information (TCI) state index to a first TCI state configuration has changed to a second TCI state configuration. The UE may select, based at least in part on the determined change, the first TCI state configuration or the second TCI state configuration to use for at least a portion of the multi-slot downlink transmission. The UE may receive the multi-slot downlink transmission during one or more slots according to the selected TCI state configuration and the TCI state index.
