Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a network node, control signaling indicating a first downlink bandwidth part (BWP) and a first uplink BWP, or a first downlink sub-band and a first uplink sub-band, or both, for performing sub-band full-duplex (SBFD) communications. The UE may receive, from the network node, a downlink control information (DCI) message indicating to switch to a second downlink BWP and a second uplink BWP, or to switch to a second downlink sub-band and a second uplink sub-band, or both. The UE may then perform full-duplex communications with the network node within the second downlink BWP and the second uplink BWP, or within the second downlink sub-band and the second uplink sub-band, or both.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) or a base station may be configured to indicate that a transmission occasion is empty while operating in a full-duplex mode. In some examples, the UE may transmit, to the base station, an indication that an uplink transmission occasion (for example, a configured grant transmission occasion) will not be used by the UE for transmitting an uplink communication. In some other examples, the base station may transmit, to the UE, an indication a downlink transmission occasion (for example, semi-persistent scheduling transmission occasion) will not be used by the base station for transmitting a downlink communication. If uplink or downlink transmission occasions are empty, the UE and the base station may each update parameters to operate in a half-duplex mode.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit, to a plurality of user equipment (UE), a set of network encoded packets generated using a set of packets. A UE of the plurality of UEs may receive a subset of the set of encoded packets and may decode the subset to determine a first set of decoded packets. The UE may receive a second set of decoded packets from the plurality of UEs. The UE may transmit feedback to the network node that indicates the successfully decoded packets of the first and second sets. The network node may receive the feedback and may determine a subset of the set of packets that was successfully decoded for each UE providing the feedback. The network node may transmit an updated set of network encoded packets to the plurality of UEs.

Abstract: Aspects described herein relate to identifying a timing advance group (TAG) for a second remote radio header (RRH) that is different from a first RRH, the TAG associated with a timing advance (TA) offset, wherein the first RRH and the second RRH are associated with a serving cell, switching from the first RRH to the second RRH in accordance with the TAG and the associated TA offset, and transmitting, on an uplink communication channel, data to the second RRH.

Abstract: Wireless communications systems may support identification or determination of a common default beam for a component carrier (CC) group (e.g., such that all CCs of a CC group may be associated with a same default beam). For example, a CC group may be configured or established to include one or more CCs (e.g., for carrier aggregation), where each CC group may share a same analog beamformer. As such, a beam (e.g., a default uplink/downlink beam) may be established as default or common across CCs of a CC group (e.g., versus default beams being configured or established for individual CCs). Such an established default beam of a CC group (e.g., a default beam common to all CCs of a CC group) may include or refer to a default downlink shared channel beam, a default sounding reference signal (SRS) beam, a default downlink control channel beam, etc.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may update a capability to a network entity periodically when the complexity, power, or memory needs of the UE change. The UE may additionally update the capability upon being triggered by a network entity, during a time scheduled by the network entity, upon the expiration of a timer, etc. The capabilities may be or include explicit values for beam switching delay, or an index selecting delay values from a table previously configured to the UE, for example. Additionally, The UE and network entity may support communications according to capability values associated with a time delay between a transmitted reference signal with repetition and the UE being ready for a downlink transmission using a beam selected based on the reference signal. This capability may indicate to the network entity to avoid scheduling downlink messages during the delay.

Abstract: Certain aspects of the present disclosure provide techniques for determining default parameters to use in the absence of a signaled uplink transmission configuration indicator (TCI) state for uplink transmissions. In some cases, a UE may determine, based on one or more rules, at least one of a default uplink beam or default path loss reference signal (PL RS) to use an uplink transmission in the absence of a signaled uplink transmission configuration indicator (TCI) state for the uplink transmission; and send the uplink transmission in accordance with the determination.

Abstract: In an aspect, a network device (e.g., BS, core network component, etc.) determines a self-interference measurement (SIM) configuration associated with null-forming at a wireless device (e.g., UE or BS), the null-forming associated with steering at least one receive beam of the wireless device and/or at least one transmit beam of the wireless device away from one or more external sources of self-interference. The network device transmits the SIM configuration to the wireless device. The wireless device performs at least one null-forming procedure in accordance with the SIM configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) receives an indication to use a transmission configuration indicator (TCI) state for receiving or transmitting a communication, the TCI state indicating non-serving cell information associated with a non-serving cell. The UE receives or transmits the communication based at least in part on the TCI state and a quasi co-location (QCL) chain rule applied for the TCI state that indicates the non-serving cell information. The QCL chain rule may indicate that a synchronization signal block (SSB) of the non-serving cell as a source reference signal provides QCL information for one or more signals of a first cell and that the one or more signals of the first cell as source reference signals provide QCL information for one or more channels or signals of a second cell. Numerous other aspects are provided.

Abstract: A wireless device, such as a user equipment (UE), may receive first scheduling information with first resources for periodic transmissions with a first beam based on a half-duplex mode. The wireless device may receive second scheduling information for second resources associated with a second beam that is incompatible with the first beam for full duplex communication including downlink reception and uplink transmission that overlaps in time. The wireless device may adjust communication in response to the first beam being incompatible with the second beam for the full duplex communication.

Abstract: Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station (BS), a handover message or the beam or panel selection message including multi-beam or multi-panel information identifying a first one or more beams or panels to remain with the source BS and a second one or more beams or panels to switch from the source BS to a target BS during a handover procedure. The UE may perform the handover procedure to switch from the source BS to the target BS with the first one or more beams or panels for communication with the source BS and the second one or more beams or panels for communication with the target BS. Numerous other aspects are provided.
