摘要: This document describes techniques for, and systems that enable, HARQ buffer management. These techniques include removing (314), based on a user device failing to transmit data during an uplink grant, data stored in a HARQ buffer. By removing the data stored in the HARQ buffer, the user device can avoid (322) transmitting, to the base station, the data stored in the HARQ buffer in response to a retransmission request from the base station.

摘要: A communications device acting as a relay device is configured to communicate with a transmitting node and a receiving node. The communications device acting as the relay is configured to receive signals representing protocol data units formed from one or more service data units via a first wireless access interface from the transmitting node according to a first automatic repeat request process for transmission to the receiving node, transmit signals representing the received protocol data units via a second wireless access interface to the receiving node according to a second automatic repeat request process, and store the protocol data units received by the receiver circuitry for transmission to the receiving node according to the second automatic repeat request process.

摘要: A method and an apparatus for triggering uplink data in a wireless LAN are disclosed. A method for receiving uplink data in a wireless LAN may comprise: a step in which an access point (AP) transmits a trigger frame for random connection; and a step in which the AP receives at least one buffer status report frame from at least one STA on a random connection transmission opportunity (TXOP) which is set on the basis of the trigger frame for random connection, wherein the random connection TXOP is allocated for a channel access attempt for transmitting the buffer status report frame of each of a plurality of non-specific STAs, and each of the at least one STA may be an STA which succeeds in the channel access among the plurality of non-specific STAs.

摘要: An apparatus of a base station includes a memory device and processing circuitry operatively coupled to the memory device. The processing circuitry processes a buffer status report (BSR) from a user equipment (UE) indicating an amount of data in a buffer of the UE. The processing circuitry further determines a ratio of WLAN uplink data to be transmitted on a WLAN channel of the UE to long term evolution (LTE) uplink data to be transmitted on a LTE channel. Furthermore, the processing circuitry encodes a protocol data unit (PDU) indicating the amount, wherein the PDU is to be transmitted to the UE.
