摘要： Systems and methods are described for streaming content to multiple devices from a shared sliding window buffer in kernel space, thereby reducing memory resource use and minimizing context/mode switching between kernel space and user space. For example, concurrent streaming sessions may be seen, e.g., as a live multimedia stream. If a live video is being transmitted as a multicast stream to many devices, rather than each device having a corresponding sliding window buffer in kernel space, each device will share a shared sliding buffer in kernel space. The sliding window buffer size will be at least large enough to stream the slowest connection speed and can be, e.g., multiple times as large as necessary, in case of the issues beyond the worst-case scenario. The system then transmits chunks of the content from the shared sliding window buffer to each of the plurality of client devices.

摘要： To increase the utilization of the radio link and to provide a low complexity approach to retransmission control with respect to a fragmenting transmission protocol and a stream of data packets considered for data transmission, there is provided a method of retransmission control with respect to a fragmenting transmission protocol and a stream of data packets considered for transmission. The method comprises the steps detecting (S12) data packets in the stream of data packets which are unnecessary retransmissions based on sequence numbers of the data packets, dropping (S14) data packets which are unnecessary retransmissions from the stream of data packets for setup of a modified stream of data packets, and transmitting (S16) the modified stream of data packets over a transmission link.

摘要： Disclosed are a method, an apparatus, and a system for adjusting a contention window size for performing channel access. In detail, the method includes: receiving a plurality of hybrid automatic repeat request acknowledgement (HARQ-ACK) responses for downlink channel(s) of the specific cell; generating a random number N (N≥0) in a contention window size; and performing the downlink transmission in the specific cell after standing by for N slots while the specific cell is idle, wherein when a ratio of negative acknowledgement (NACK) among the plurality of HARQ-ACK responses is equal to or more than a reference value, the contention window size becomes larger than a previous value, and when the ratio of the NACK among the plurality of HARQ-ACK responses is less than the reference value, the contention window size is reset to a minimum value.

摘要： A method of moving a receiving window in a wireless mobile communication system, wherein the AM RLC of the transmitting side sends information of the last discarded SDU regardless of continuity of the discarded SDUs. The AM RLC of the receiving side checks whether all SDUs from the start point of the receiving window up to the last discarded SDU are successfully received, delivers the SDUs that are successfully received to an upper layer, and discard only those SDUs that are not successfully received.

摘要： A method and an apparatus for sending Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) feedback information are provided. The User Equipment (UE) receives a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH) sent by a base station, determines a number of downlink subframes corresponding to the HARQ-ACK feedback information sent in the PUSCH of each CC in the current uplink subframe, the Uplink (UL) Downlink Assignment Index (UL DAI) obtained from the UL Grant of the PDCCH, a sum of the number of PDSCH subframes received from a HARQ-ACK bundling window and a number of PDCCHs indicating the downlink SPS releasing, and a size of the HARQ-ACK bundling window, and sends HARQ-ACK feedback information of each CC via the PUSCH in the current uplink subframe. A number of bits of the HARQ-ACK feedback information of each CC is determined according to the number of the downlink subframes.
