    摘要： Certain aspects of the present disclosure relate to techniques and apparatus for improving decoding latency and performance of Polar codes. An exemplary method generally includes generating a codeword by encoding information bits using a first code of length K to obtain bits for transmission via K channels, wherein the first code comprises a polar code, further encoding the bits in each of the K channels using a second code of length M, and transmitting the codeword.

    摘要： Certain aspects of the present disclosure provide techniques for transmitting and processing channel state information (CSI) reference signals (CSI-RS). An exemplary method includes determining a configuration of channel state information reference signals (CSI-RSs), wherein the configuration indicates a set of resource elements (REs) to be used for CSI-RSs and a first mapping of CSI-RS ports to the set of REs; sending an indication of the configuration of the CSI-RSs; and transmitting the CSI-RSs according to the determined configuration.

    摘要： An example method of decoding video data includes obtaining, from a coded video bitstream and for a current block of the video data, an indication of an intra-prediction mode that identifies an initial predictive block; filtering, in parallel, samples in a current line of a plurality of lines of the initial predictive block based on filtered values of samples in a preceding line of the plurality of lines and unfiltered values of samples in the current line to generate filtered values for samples for the current line; and reconstructing, using intra prediction, values of samples of the current block based on the filtered values of the samples of the current initial predictive block and residual data for the current block that represents a difference between the filtered values of the samples of the current initial predictive block and the values of samples of the current block.

    摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a target network node may receive, from a source network node, delay status information associated with a user equipment (UE) served by the source network node, wherein the delay status information is associated with one or more logical channels (LCHs). The target network node may receive, from the UE during a random access channel (RACH) procedure, one or more messages that include one or more delay status reports associated with the one or more LCHs. The target network node may transmit, to the UE during a handover of the UE from the source network node, one or more messages indicating one or more uplink scheduling parameters for the one or more LCHs based on the delay status information and the one or more delay status reports associated with the one or more LCHs.

    摘要： This disclosure provides methods, components, devices and systems for extending distributed resource units (dRUs) beyond 80 MHz. Some aspects more specifically relate to supporting enhanced tone distribution mapping schemes and signaling. In some examples, a wireless station may receive, from an access point, scheduling information for a physical layer (PHY) protocol data unit (PDU) (PPDU) to be transmitted by one or more wireless stations including the wireless station over a wireless channel. The scheduling information may indicate one or more dRUs within the wireless channel, each dRU comprising a respective set of tones distributed across a distribution bandwidth of the wireless channel. The distribution bandwidth may be larger than 80 MHZ, and the one or more dRUs including a first dRU allocated to the wireless station. The wireless station may modulate a plurality of symbols for the PPDU onto the set of tones of the first dRU. The wireless station may transmit the plurality of symbols via the first dRU.
