摘要： Certain aspects of the present disclosure provide techniques for slot aggregation in new radio (NR) systems. A method of wireless communication by a user equipment (UE) includes receiving radio resource control (RRC) signaling providing a semi-static configuration for transmission and/or reception of a repeated transport block (TB) and/or a different TB in each of a plurality of aggregated slots. The UE transmits or receives the TBs in the plurality of aggregated slots based on the semi-static configuration. Another method is provided in which the UE transmits and/or receives a demodulation reference signal (DMRS) in each of a plurality of aggregated slots, each DMRS associated with a repeated TB or a different TB in the slot. The UE determines, based on received signaling, whether the DMRS use a same precoder or a different precoder and modulates and/or demodulates the TBs in the plurality of aggregated slots based on the determination.

摘要： Systems and techniques are described for encoding and/or decoding data based on motion estimation that applies variable-scale warping. An encoding device can receive an input frame and a reference frame that depict a scene at different times. The encoding device can generate an optical flow identifying movements in the scene between the two frames. The encoding device can generate a weight map identifying how finely or coarsely the reference frame can be warped for input frame prediction. The encoding device can generate encoded video data based on the optical flow and the weight map. A decoding device can generate a reconstructed optical flow and a reconstructed weight map from the encoded data. A decoding device can generate a prediction frame by warping the reference frame based on the reconstructed optical flow and the reconstructed weight map. The decoding device can generate a reconstructed input frame based on the prediction frame.

摘要： Aspects of the present disclosure describe receiving, from at least one cell of a zone of multiple cells, a zone-specific signal related to the zone of multiple cells, wherein the zone of multiple cells operate using synchronized timing, acquiring, based on the zone-specific signal, a timing synchronization with a cell of the zone of multiple cells, and communicating with the cell based on the timing synchronization.

摘要： Aspects of the disclosure relate to rate-matching a stream of bits encoded using polar codes. An exemplary method generally includes determining a mother code size (N) for transmitting an encoded stream of bits based, at least in part, on a minimum supported code rate for transmitting the encoded stream of bits (Rmin), a control information size of the encoded stream of bits (K), a number of coded bits for transmission (E), and a maximum mother code size (Nmax), encoding a stream of bits using a polar code of size (N, K) and storing the encoded stream of bits in a circular buffer, and performing rate-matching on the stored encoded stream of bits based, at least in part, on a comparison among the mother code size (N), the control information size of the encoded stream of bits (K), and the number of coded bits for transmission (E).

摘要： Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.

摘要： Aspects of the present disclosure relate to techniques for retransmission of code block groups when code block group (CBG) level feedback is unreliable. A user equipment (UE), in a first slot, transmits a first CBG feedback corresponding to a first set of CBGs received from a base station. In a second slot after the first slot, the UE receives downlink control information (DCI) and a first cyclic redundancy check (CRC). The first CRC is generated based on the DCI and further scrambled by a first concatenation of CBG feedbacks as decoded by the base station. The UE generates a second CRC based on the DCI and further scrambled by a second concatenation of CBG feedbacks including the first CBG feedback. The UE determines that the base station correctly decoded the first CBG feedback based on a comparison of the first CRC and the second CRC.

摘要： Methods, systems, and devices for wireless communication are described. A network access device may select a search space configuration for transmission of group(s) of one or more control channel elements (CCEs) to convey a downlink control information (DCI) message. The search space configuration may include a cross-coreset configuration, such as a cross-control channel subband configuration, a cross-symbol configuration, and/or a cross-beam configuration. The network access device may transmit the DCI message according to the selected search space configuration. A user equipment (UE) may monitor, based on the search space configuration, the group(s) of one or more CCEs to detect DCI messages. The UE may detect a DCI message for it and decode the DCI message based on the monitoring. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communication are described. To encode a vector of bits using a polar code, an encoder may allocate information bits of the vector to polarized bit-channels associated with a channel (e.g., a set of unpolarized bit-channels) used for a transmission. In some cases, the polarized bit-channels may be partitioned into groups associated with different values of some associated reliability metric (s). The information bits may be allocated to the polarized bit-channels based on the reliability metrics of the different polarized bit-channels and the overall capacity of a transmission. That is, the bit locations of a transmission may depend on the reliability metrics of different polarized bit-channels and the overall capacity of the transmission. To facilitate puncturing, the overall capacity of the transmission may be adjusted and the unpolarized bit-channels may be partitioned into polarized bit-channels based on the adjusted capacity.
