摘要： Systems, apparatuses, and methods for implementing data recovery techniques for lossy wireless links are disclosed. A transmitter is configured to encode a video stream and wirelessly transmit the encoded video stream to a receiver, with the video stream representing a virtual reality (VR) rendered environment. The transmitter partitions the video stream into a plurality of substream components based on frequency. Motion vector parameters are calculated for the lowest frequency substream component of the video stream only, and the motion vector parameters are sent to the receiver using a low MCS level. When the receiver receives the motion vector parameters, but the receiver does not receive the lowest frequency component of a given chunk, the receiver uses the motion vector parameters to reconstruct the lowest frequency component of the given chunk by extrapolating from a corresponding chunk of the previous video frame.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a set of STAs for at least one of a MU-MIMO transmission or an OFDMA transmission. In certain aspects, the set of STAs may be associated with a set of acceptable MCSs determined based on MCSs excluded from a union of a plurality of sets of unacceptable MCSs. In certain other aspects, each set of unacceptable MCSs in the plurality of sets of unacceptable MCSs may be associated with a different STA in the set of STAs. The apparatus may transmit the at least one of the MU-MIMO transmission or the OFDMA transmission to the set of STAs.

摘要： Methods, systems, and devices for data rate adaptation to extend the range of wake-up radio transmissions sent to a wake-up radio of a station (STA). Data rate adaptation procedures may be used to select a data rate for wake-up radio transmission based on one or more identified parameters. An access point may execute one or more different types of rate adaptation procedures to select the appropriate data rate. In some examples, the access point may select a data rate of wake-up radio transmissions based on one or more messages failing to be successfully decoded. In some examples, the access point may select a data rate of wake-up radio transmissions based on a distance between the access point and the station. In some examples, the access point may select a data rate of wake-up radio transmission based on information identified during a training procedure.

摘要： Coding sub-channel selection involves, in an embodiment, determining, from sub-channels that are defined by a code and that have associated reliabilities for input bits at input bit positions, a first number of the sub-channels to carry bits that are to be encoded. A second number of the sub-channels, greater than the first number, are selected. The second number of sub-channels are selected to provide exactly the first number sub-channels to be available to carry the bits that are to be encoded.

摘要： Techniques are described herein to dynamically control a number of hybrid automatic repeat requests (HARQ) transmissions based at least in part on flow characteristics of a data flow. Data included in a transport block may be grouped into one or more data flows based on a variety of factors. A set of performance benchmarks may be associated with each data flow. Flow characteristics for each data flow may be measured. A network entity may determine a number of HARQ transmissions to be transmitted during a HARQ procedure based on measured flow characteristics satisfying the performance benchmarks. For example, if a performance benchmark is not satisfied by its associated flow characteristic, the network entity may request additional HARQ transmissions during the HARQ procedure.

摘要： A user equipment (UE) may be categorized into one or more capability categories based on its ability to generate hybrid automatic repeat request (HARQ) responses within a predetermined delay or slot. HARQ timing management may consider a UE capability category that is UE dependent. The UE may provide a HARQ response different (i.e., advancing or delaying HARQ timing) than the specified or default HARQ response timing of the UE's category with some limitations and constraints. A constraint is a condition in which one or more operation parameters of the UE do not satisfy or meet a predetermined level or setting.

摘要： An encoder receives a sequence of packets. For each packet, the encoder selects a window of at least previous packets in the sequence of packets. The encoder identifies in the window one or more earlier packets among the previous packets and one or more later packets separated from the one or more earlier packets by a gap including gap packets. The encoder encodes the one or more earlier packets and the one or more later packets into a forward error correction (FEC) packet corresponding to the packet, without using any of the gap packets, and transmits the FEC packet and the packet.
