Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit an indication of neural network weights to one or more user equipments (UEs). The neural network weights may be for one or more shared layers of a federated learning neural network. The UEs may train a personalized layer of the neural network using the weights and data at the UEs. The UEs may transmit layer updates to the network entity. The network entity may train the neural network based on the updates. The UEs may send a transmission to the network entity that may be processed according to the neural network at the UEs and the network entity.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving first scheduling information indicating a sidelink uplink control information (S-UCI) resource, receiving second scheduling information indicating one or more physical sidelink feedback channel (PSFCH) resource, and transmitting control information via at least one of the S-UCI resource or the one or more PSFCH resources.

Abstract: Methods, systems, and devices for wireless communications are described for block feedback of multiple semi-persistent scheduling (SPS) occasions. Block feedback may be provided based on variable feedback timing values that are associated with one or more SPS occasions. A user equipment (UE) may determine feedback for each of two or more SPS occasions, and transmit a block feedback that indicates the feedback. A separate feedback timing between a SPS occasion and uplink feedback resources may be provided for multiple SPS occasions, which are associated with a single uplink feedback resource. Alternatively, a minimum feedback timing value and a maximum feedback timing value may be configured for a particular uplink resource, and block feedback for multiple SPS occasions within the minimum and maximum feedback timing values may be reported in the uplink feedback resource.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may include multiple antenna arrays used to support wireless communications. The antenna arrays may be located at different parts of the UE and may allow the UE to flexibly perform beamforming communications. The antenna arrays maybe configured as antenna sets, and the size of each antenna set may vary based on the configuration of the UE. For example, a UE may include a foldable display having multiple foldable display units, and the communication parameters used for transmission and reception of signals via the antenna arrays may depend on the configuration of the foldable display units. In some aspects, a state of the foldable display units or the arrangement of the antenna arrays relative to one another may be used to configure and perform beamforming communications between the UE and a base station.

Abstract: Methods, systems, and devices for wireless communications are described in which a first wireless device and second wireless device may establish communications using a first beam and a second beam. The first wireless device may perform separate radio link monitoring (RLM) procedures to monitor beam quality for each of a transmit beam and receive beam that are used for communications with a second wireless device. The separate RLM procedures may be used at the first wireless device to determine that one of the transmit or receive beams is experiencing a quality degradation or a radio link failure (RLF), and an RLF indication may be provided to the second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive one or more transmissions from one or more UEs in a first slot, including a first transmission from a second UE. The first UE may receive the first transmission using a receiver configured with a first gain and may decode the first transmission. The UE may determine a correspondence (e.g., a temporal correlation) between the first slot and a second slot and may configure the receiver with a second gain at the beginning of the second slot based on the correspondence. The UE may determine that a total received signal power in the second slot is associated with the total received signal power in the first slot. The UE may decode one or more transmissions in the second slot based on the receiver having the second gain at the beginning of the slot.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may select an orthogonal metric based at least in part on at least one of each direction of a plurality of directions to transmit millimeter wave discovery signals or a location parameter associated with the transmitting device. The transmitting device may transmit, in the each direction of the plurality of directions, the millimeter wave discovery signals, where the each transmitted millimeter wave discovery signal has a different orthogonal metric applied that was selected based at least in part on the at least one of the each direction or the location parameter.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques for multiple transmission reception points (TRPs) in a cluster may coordinate scheduling and communications with a user equipment (UE). Different TRPs may allocate uplink resources for one or more UEs within a coordinated cluster to transmit feedback information. A first TRP may provide a first set of resources that one or more associated UEs may use to transmit acknowledgment (ACK) feedback to indicate successful receipt of a downlink transmission of the first TRP, and one or more other TRPs of the coordinated cluster may provide a second set of resources that the one or more UEs may use to transmit negative acknowledgment (NACK) feedback to indicate that a downlink transmission of the first TRP was lost. The second set of resources may include non-orthogonal multiple access (NOMA) resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a negative acknowledgement (NACK) corresponding to a failed communication from a first transmission/reception point (TRP) included in a coordinated multipoint network. The UE may monitor a control channel associated with a second TRP included in the coordinated multipoint network based at least in part on transmitting the NACK, wherein the first TRP and the second TRP use different frequency bands. The UE may receive a retransmission of the failed communication based at least in part on monitoring the control channel. Numerous other aspects are provided.

Abstract: Methods and apparatus for controlling switching between resources and/or communicating resource change information in a wireless communications system are described. Various methods and apparatus are well suited for use in a decentralized wireless communications network, such as a decentralized peer to peer wireless network, where an individual communications device self allocates resources and makes resource switching decisions. A first communications device may decide that there is a need to switch from the first communications resource corresponding to a first identifier to a second communications resource corresponding to a second identifier, e.g., because of interference. The first communications device generates and transmits a broadcast change signal indicating a change from the first communications resource associated with the first identifier to a second communications resource associated with the second identifier.

Abstract: Methods and apparatus related to the implementation and selection of alterative control information reporting formats are described. A control information reporting format, corresponding to a connection between a wireless terminal and a base station, e.g., for an uplink dedicated control channel, is selected, as a function of at least one of: an application being executed, device capability information, channel condition information, system loading information, and user quality of service information. Different wireless terminals may use different control information reporting formats at the same time. The same wireless terminal may use a different control information reporting format at different times.
