Data transmission method and network device
When a condition of handing over user equipment from a cell in which a first network device is located to a cell in which a second network device is located is met, the first network device sends first information to the second network device, where the first information includes at least one of a CWND, a slow start threshold, a window scale factor, a RWND, and a TCP segment length; the slow start threshold is a value of demarcation between a slow start state and a congestion state; the window scale factor is a window scale factor carried in a SYN packet when a TCP connection is set up; the RWND is a maximum data volume that can be received by the user equipment; and the TCP segment length is a length of a maximum TCP segment that can be sent by the first network device.

Uplink OFDMA processing in WLANs
This disclosure relates to orthogonal frequency division multiple access (OFDMA) communication in wireless local area networks (WLANs). According to some embodiments, a downlink OFDMA frame may be transmitted. An uplink OFDMA frame including acknowledgements associated with the downlink OFDMA frame may be received. The uplink OFDMA frame may be processed, in some instances including determining which devices receiving the downlink OFDMA frame transmitted an acknowledgement associated with the downlink OFDMA frame in the uplink OFDMA frame.

Multiple data channel based channel state information reports
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling that may identify a configuration for channel state information reporting associated with both a first target block error rate and a second target block error rate. The UE may receive one or more reference signals associated with the channel state information reporting. Further, the UE may transmit, to the base station, the channel state information reporting that may include first channel state information for the first target block error rate and second channel state information for the second target block error rate. In some examples, each of the first channel state information and the second channel state information may be based on the received reference signals.
Adaptive causal network coding with feedback
Techniques are disclosed for an adaptive and causal random linear network coding (AC-RLNC) with forward error correction (FEC) for a communication channel with delayed feedback. An example methodology implementing the techniques includes transmitting one or more coded packets in a communication channel, determining a channel behavior of the channel, and adaptively adjusting a transmission of a subsequent coded packet in the first channel based on the determined channel behavior. The communication channel may be a point-to-point communication channel between a sender and a receiver. The channel behavior may be determined based on feedback acknowledgements provided by the receiver. The subsequent coded packet may be a random linear combination of one or more information packets.

Uplink ACK resource allocation in new radio
A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.

A LOW COMPLEXITY PUNCTURING METHOD FOR LOW-RATE POLAR CODES
Features of the present disclosure implement a low complexity rate-matching design for polar codes that supports full rate-matching granularity, in some cases without good bit re-estimation after puncturing. In particular, features of the present disclosure provide techniques for adjusting the information bits allocation based on the number of punctured bits (P) for block puncturing polar codes. Particularly, features of the present disclosure determine the number of information bits for each sector based on a capacity formula after the puncturing.
