Abstract: A receiving device may be either a UE or a base station. The receiving device may receive, from a transmitting device, communication based on a current reference signal (RS) pattern. The receiving device may determine, based on the received communication, at least one updated RS pattern for at least one resource block (RB). The at least one updated RS pattern may include at least one updated energy per resource element (EPRE) value for one or more RS tones. Further, the receiving device may transmit, to the transmitting device, a report of the at least one updated RS pattern. The report may correspond to at least one of an absolute value or a relative value of the at least one updated EPRE value for the one or more RS tones.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a receiving device selecting a receive beam for receiving a signal from a transmitting device based on a relative direction of the transmit beam used to transmit the signal. A first wireless device may receive, from a second wireless device, an indication of a first angular range. The first angular range may be associated with a set of transmit beams for the second wireless device and correspond to at least two transmit beams of the set of transmit beams. The first wireless device may select a receive beam from a set of receive beams based on the first angular range and receive a reference signal, from the second wireless device, using the selected receive beam. The first device may also transmit channel information, to second wireless device, based on the reference signal.

Abstract: Certain aspects of the present disclosure provide techniques for beam failure detection in a second band based on measurements in a first band. A method that may be performed by a user equipment (UE) includes receiving one or more reference signals (RSs) on a first radio frequency band and initiating a beam failure recovery on a second radio frequency band based, at least in part, on the one or more RSs on the first radio frequency band. The UE may measure the one or more RSs on the first radio frequency band and perform beam failure detection (BFD) for the second radio frequency band based, at least in part, on one or more measurements of the one or more RSs on the first radio frequency band.

Abstract: Various aspects relate generally to the beam management procedures in wireless communications systems. Some aspects more specifically relate to the selection of beams for communications to and from a UE and a network entity based on quantized orientation information for a user equipment (UE). In some implementations, a network entity can use the quantized orientation information and a machine learning model to predict a set of beams that may be suitable for communications to and from the UE and the network entity, which may be a subset of the beams that the network entity can generally use for communications to and from the UE and the network entity.

Abstract: Embodiments include methods that may be performed by a processor of a mobile device and a processor of a base station for managing beam failure recovery (BFR). The processor of the mobile device may determine whether a beam failure of a communication link with a base station has occurred, determine whether contention free random access (CFRA) resources have been configured in response to determining that a beam failure has occurred, and initiate contention based random access (CBRA) in response to determining that CFRA resources have not been configured. The processor of the base station may receive from the mobile device a message initiating CBRA, determine whether a downlink beam or quasi-colocation (QCL) assumption a downlink resource of a physical random access channel (PRACH) is different from any active downlink beam or QCL assumption, and perform CBRA with the mobile device.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may switch semi-persistently scheduled (SPS) or configured grant (CG) transmissions for a user equipment (UE) across component carriers according to a resource switching pattern to avoid resource conflict with control information on one or more component carriers. The resource switching pattern may have multiple flows spanning different component over a time interval for redundancy. According to some aspects, a base station may transmit a synchronization signal block (SSB) in one of a set of flexible SSB locations or candidate SSB locations, where each of the set of candidate SSB locations is associated with a respective SSB identifier.

Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), data from one or more beam pairs of a plurality of beams at least partially concurrently; determining, by the UE, one or more signal parameters for the one or more beam pairs; determining, by the UE, one or more joint quasi co-located (QCL) indicators for the one or more beam pairs and one or more non-joint QCL indicators for the one or more beam pairs; and transmitting, by the UE, a measurement report including the one or more joint QCL indicators and the one or more non-joint QCL indicators. In another aspect, a method of wireless communication includes determining a particular beam or beams for transmitting second data based on the measurement report; and transmitting the second data using the particular beam or beams. Other aspects and features are also claimed and described.

Abstract: Wireless communications systems and methods related to indicating antenna configuration information and neural network information are disclosed. Neural network information may be selected for an encoder side based on an antenna configuration of a first device housing the encoder. This information may be transmitted with the antenna configuration information to a second device, which may jointly train the neural network with the first device. The first device may further transmit one or more weights after the training, which are stored with the antenna configuration information at the second device as well. When a third device with similar antenna configuration as the first device establishes communication with the second device, the second device may transmit neural network information, as well as weights, to the third device. The third device may use this information, instead of default information, to speed up neural network initialization and training.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a user equipment (UE), a message that indicates whether the UE received a downlink transmission from the base station in a first frequency range. The base station may schedule one or more reference signal (RS) transmissions in the first frequency range and one or more RS transmissions in a second frequency range based at least in part on the message received from the UE, and reschedule the downlink transmission on a component carrier in either the first frequency range or the second frequency range based at least in part on channel quality information that is determined from the one or more RS transmissions in the first frequency range and the one or more RS transmissions in the second frequency range. Numerous other aspects are provided.
