摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a channel state information (CSI) report configuration including configuration information that identifies a channel measurement resource associated with a first numerology and configuration information that identifies an interference measurement resource associated with a second numerology that is different from the first numerology. The UE may perform a channel measurement on the channel measurement resource associated with the first numerology and an interference measurement on the interference measurement resource associated with the second numerology. The UE may transmit, to the base station, a CSI report based at least in part on the channel measurement and the interference measurement. Numerous other aspects are described.

摘要： Methods, systems, and devices for wireless communications are described. A transmitting device may perform distribution matching on at least a first subset of a set of bits, such as the bits of transport block. The distribution matching may include a variable-to-fixed (v2f) distribution matching procedure in which a ratio between a quantity of input bits to output interim symbols for the v2f distribution matching procedure is variable. The distribution matching include evaluating, after each instance of the v2f distribution matching procedure, whether additional bits remain for distribution matching, and if so, whether to perform an additional instance of the v2f distribution matching procedure or an alternative distribution matching procedure on the remaining bits. Corresponding techniques for a receiving device are also described, including distribution dematching techniques based on a v2f distribution dematching procedure.

摘要： Certain aspects of the present disclosure provide techniques for sounding and precoding uplink transmissions using one or more machine learning models. An example method generally includes generating a sounding reference signal (SRS) using an SRS deep neural network (DNN); transmitting, to a network entity, the generated SRS in one or more resource elements (REs); receiving, from the network entity, information identifying a precoding matrix to use for uplink transmissions on a shared channel; precoding uplink transmissions based on the identified precoding matrix; and transmitting, to the network entity, the precoded uplink transmissions on the shared channel.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration that defines a quantity of additional guard resource elements (REs) in a frequency domain between different frequency division multiplexed demodulation reference signal (DMRS) code division multiplexing (CDM) groups. The additional guard REs in the frequency domain may not be associated with signal transmissions. The UE may perform a channel estimation based at least in part on the quantity of additional guard REs in the frequency domain between the different frequency division multiplexed DMRS CDM groups. Numerous other aspects are described.

摘要： A configuration for resource allocation for PDCCH with multi-relay based communication. The apparatus determines a transmission time of a signal comprising a sequence of a plurality of PDCCHs to a target node. At least one relay is between the base station and the target node. The apparatus transmits, to each of the at least one relay, a relay configuration comprising scheduling information for each of the at least one relay to relay the signal. The scheduling information is based on a determination of the transmission time of the signal to the target node.

摘要： Methods, systems, and devices for wireless communications are described in which a receiving device, such as a base station or user equipment (UE), may receive an input signal that is modulated according to a probabilistic amplitude shaping (PAS) modulation technique. The receiving device may determine an associated channel noise estimate and may scale the input signal and the channel noise estimate based on a probability distribution parameter that is associated with the PAS modulation. The receiving device may demap the modulation constellation of the input signal based on the scaled input signal and the scaled channel noise estimate and provide one or more bits associated with the PAS modulated constellation. The probability distribution parameter may be estimated at the receiving device, or the transmitting device may provide the probability distribution parameter to the receiving device.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with multiple transmit receive points (TRPs) in a frame based equipment mode. A wireless node (e.g., the UE and/or one or more of the multiple TRPs) may determine, among the UE and the multiple TRPs, an initiating node that acquired a current channel occupancy time. The wireless node may determine a transmission pattern that includes one or more idle periods based at least in part on a fixed frame period structure associated with the initiating node that acquired the current channel occupancy time. The wireless node may refrain from transmitting during the one or more idle periods, wherein the one or more idle periods include at least an idle period associated with the wireless node. Numerous other aspects are described.

摘要： Methods, systems, and devices for wireless communication are described to support replacing values of one or more information bit vectors with one or more corresponding sets of parity bits. A first wireless device may replace an information bit vector with a parity bit vector, using a set of information bits of the information bit vector and based on a parity check matrix, which may result in generating the set of information bits at an information bit vector corresponding to a parity bit column of the parity check matrix, during encoding. The first wireless device may perform a transmission to a second wireless device, which may receive the transmission, decode the set of information bits to the information bit vector corresponding to the parity bit column. The second wireless device may replace other bit estimates of a vector corresponding to an information bit column with the set of information bits.

摘要： A UE in one of an RRC idle mode or an RRC inactive mode may generate an emergency message including one or more of GPS coordinates, a timestamp, a UE ID, a personal ID of a user of the UE, an emergency level, or an emergency type, and transmit the emergency message to an NR-NTN. The emergency message may be transmitted in a dedicated time or frequency resource. The base station may receive the emergency message from the UE and forward the UE information to a network.
