摘要: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a base station and/or UE. The apparatus can calculate a number of coded bits based on a number of downlink control information (DCI) information bits. The apparatus can also determine an amount of one or more code blocks (CBs) in DCI based on at least one of the number of coded bits or the number of DCI information bits, each of the one or more CBs including a plurality of the coded bits. Moreover, the apparatus can transmit a physical downlink shared channel (PDSCH) including the DCI, wherein the DCI includes at least one of the one or more CBs or one or more coded blocks. The apparatus can also encode the one or more CBs in the DCI based on the determined amount of one or more CBs.

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, an uplink grant message in a first fixed frame period (FFP) in frame based equipment mode, and transmit data to the base station in a first part of a second FFP, based at least in part on information in the uplink grant message. Numerous other aspects are provided.

摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive an indication that a transmission of first data is to be modified and that second data is to be transmitted in place of a portion of the transmission of the first data; and identify a single time at which the transmission of the first data is to be canceled and transmission of the second data can begin, based at least in part on capabilities of the UE. Numerous other aspects are provided.

摘要: Various aspects of the present disclosure generally relate to signaling in frame-based equipment (FBE) mode for channel occupancy time (COT) sharing. In some aspects, a user equipment (UE) may receive, in association with an FBE mode, a message associated with a designation of the UE for either COT sharing or non-COT sharing. The UE may detect whether there is an initial signal at a boundary of a time frame for COT and sleep, monitor, or communicate during the time frame, based at least in part on the designation and the detecting. Numerous other aspects are provided.

摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a wakeup signal (WUS) associated with a discontinuous reception (DRX) ON duration; determine that a grant was not detected in the DRX ON duration; and perform an action based at least in part on whether the WUS is specific to the UE or is associated with a group of UEs. Numerous other aspects are provided.

摘要: Wireless communications systems and methods related to hybrid repeat request (HARQ) with rate splitting are provided. A first wireless communication device communicates, with a second wireless communication device, a first communication signal including a plurality of information bits. The first wireless communication device determines a number of bits in the plurality of information bits to be repeated in a second communication signal based on channel capacity information. The first wireless communication device communicates, with the second wireless communication device, the second communication signal including the plurality of information bits and a repetition of a subset of the plurality of information bits, where the subset of the plurality of information bits includes the determined number of bits.

摘要: The disclosure relates in some aspects to information encoding. Information encoding may involve puncturing bits of a codeword or repeating bits of a codeword. The disclosure relates in some aspects to selecting a puncturing or repetition pattern. In some aspects, a puncture pattern for data encoding is selected based on a criterion that the output and the repetition input of an XOR are not erased. In some aspects, a repetition pattern for data encoding is selected based on a criterion that repetition not be applied for the output and the repetition input of an XOR.

摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an encoding device may determine a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded; may determine a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits; may add the codeword bit to the codeword; and may transmit the codeword. Numerous other aspects are provided.

摘要: Various aspects of the disclosure relate to mapping different information to different sub-channels. For example, information for different users may be mapped to different Polar code sub-channels. In some aspects, the mapping may be unbalanced in that different information is mapped to different sub-channels according to the quality (e.g., in terms of error probability) of the sub-channels and a criterion associated with the information. For example, control information for users that are experiencing the worst channel quality (e.g., in a wireless communication channel) may be mapped to the Polar code sub-channels that have the best quality.
