摘要： Aspects of the present disclosure provide various hybrid automatic repeat request (HARQ) retransmission indication schemes used in a HARQ retransmission process. The HARQ retransmission indication can implicitly or explicitly indicate which part of a transport block (TB), code block group(s), or code block(s) is/are being retransmitted so that the receiver can associate the retransmitted TB, code block group(s), code block(s) with the correct prior reception, for example, for HARQ combining purposes.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) on a plurality of antenna ports. The UE may transmit the SRS on one or more virtual antenna ports, the one or more virtual antenna ports being based at least in part on the plurality of antenna ports. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

摘要： Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

摘要： Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.

摘要： Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

摘要： Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARD) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

摘要： In some aspects, multi-slot transport block (TB) configurations for communicating data between wireless devices, such as between a base station and a user equipment (UE), in a wireless communication system are described. Some examples of multi-slot configurations enable the communication of large payloads. For example, an application of a wireless device may jointly process data from a large file or other large set of packets. In such examples, the wireless device transmitting the large file may utilize a multi-slot TB including multiple TB segments corresponding to respective slots of a transmission. Similarly, a wireless device receiving the large file may utilize the multi-slot TB configuration for receiving the data.

摘要： Methods, systems, and devices for wireless communications are described. A first device and a second device may communicate via a channel. The first device may generate and transmit a reference signal, which may be a distortion probing reference signal with a high peak to average power ratio. In one implementation, the first device may use the reference signal as an input for a neural network model to learn a nonlinear response of the second device transmission components. In another implementation, the second device may sample the generated reference signal, and use the samples as inputs for a neural network model to learn the nonlinear response. The first device and the second device may exchange signaling based on learning the nonlinear response, and each device may compensate for the nonlinear response when communicating via the channel.

摘要： The disclosed methods and apparatuses for round trip time (RTT) based positioning include generating or receiving a measurement report. The measurement report includes, for at least one transmission-reception point (TRP), a user equipment (UE) time difference and an offset of the at least one TRP. The UE time difference is a difference of a UE transmission time of an uplink reference signals (UL RS) to the at least one TRP and an earliest reception time representing a time of arrival (TOA) at the UE of an earliest path of a downlink reference signal (DL RS) from the at least one transmission-reception point (TRP). The offset is a difference of a stronger reception time representing a TOA at the UE of a stronger path of the DL RS from the at least one TRP and the earliest reception time.
