Embodiments of this application provide a scheduling request processing method and a terminal device. The scheduling request processing method includes: determining, by a terminal device, whether there is a regular BSR associated with a first logical channel that is triggered and has not been canceled; and if a regular BSR associated with the first logical channel is triggered and has not been canceled, and the terminal device has no uplink resource available to transmit data of the first logical channel, and a first timer of the terminal device is not running, triggering, by the terminal device, an SR, where the first timer is configured to delay transmission of the SR. According to the scheduling request processing method provided in the embodiments of this application, when the terminal device has no uplink resource available to transmit the data of the logical channel associated with the BSR, the SR is triggered to implement uplink resource scheduling, thereby satisfying a QoS requirement of the data carried on the logical channel.

A method and device for processing data are provided. The method comprises: a terminal device controlling the current state of a copied data transfer function according to first indication information, wherein the first indication information is used for indicating whether the copied data transfer function is enabled; and the terminal device processing, according to the current state of the copy data transfer function, each RLC service data unit (SDU) in a first radio link control (RLC) cache and a second RLC cache, wherein the first RLC cache corresponds to a first RLC entity, and the second RLC cache corresponds to a second RLC entity.

The present disclosure relates to transmitting data over a physical uplink shared channel in a wireless communication system by using an asynchronous hybrid automatic repeat request, HARQ. An exemplary apparatus comprises a first timer configured to start upon uplink data transmission and stop after a first predetermined time; a second timer configured to start upon stop of the first timer and to stop after a second predetermined time; a receiver for receiving downlink control information including a positive acknowledgement for uplink new data transmission or retransmission, the receiver being configured to perform the receiving only when the first timer is stopped and the second timer is running, wherein the second timer is further configured to stop upon receiving the positive acknowledgement. Moreover, an apparatus for receiving the data and transmitting the control channel is provided as well as the corresponding transmitting and receiving method.

A method of configuring downlink timings and transmitting a random access response message is provided for a random access procedure in a Long Term Evolution (LTE) system supporting carrier aggregation. The method for adjusting timing of a terminal in a wireless communication system supporting carrier aggregation of at least one carrier includes transmitting a Random Access Preamble to a base station, and receiving a Random Access Response with a Timing Advance Command (TAC) for commanding uplink timing adjustment from the base station, wherein the Random Access Response comprises information indicating a Timing Advance Group (TAG) to which the TAC is applied.

A first allocation of physical resources for uplink transmission is received over a downlink signaling channel. Data of a logical channel is received. A first block is transmitted over the first allocated physical resources in response to receipt of the data of the logical channel. A timer is initiated in response to transmission of the first block. In response to an expiration of the timer and not receiving a second allocation of physical resources, a first type of request from a plurality of types of requests is selected and the selected first type of request for the second allocation of physical resources is transmitted over an uplink signaling channel. The second allocation of physical resources is received in response to the transmitted first type of request. A second block is transmitted in response to the second allocation of physical resources over the second allocated physical resources.

A method of operating multiple time alignment timers (TimeAlignmentTimer) is provided for facilitating communication between and evolved Node B (eNB) and a User Equipment (UE) in a Long Term Evolution (LTE) system supporting multiple carriers. The method includes starting a first TAT of a first group including the primary cell, starting a second TAT when Timing Advance (TA) information on a second group not including the primary cell is received; and determining transmission of at least one of a Hybrid Automatic Repeat Request Acknowledgement/Negative-acknowledgement (HARQ ACK/NACK), a physical uplink control channel, and a sounding reference signal according to a start and an expiration of at least one of the first and second TATs.

A wireless telecommunications system supports a DRX operating mode for communications between a base station and terminal device, which includes a regular repeating cycle of DRX inactive periods when the terminal device monitors a downlink channel from the base station and DRX active periods when the terminal device enters a power-saving mode not monitoring the downlink channel. The terminal device transmits uplink signaling, triggering subsequent downlink signaling, that may include acknowledgement signalling for a previous downlink transmission or an uplink transmission resources request. The base station receives the uplink signalling, determines time of an upcoming DRX inactive period for the terminal device, and delays transmitting downlink signalling responding to the uplink signalling until the upcoming DRX inactive period. The terminal device enters the power saving mode after transmitting the uplink signalling and exits the power saving mode for the DRX inactive period to monitor the downlink channel for downlink signalling.

A method and apparatus for discontinuous reception for a shortened transmission time interval and processing time includes a device monitoring for data transmission scheduling assignments during an active time of a DRX cycle, and detecting a transmission during the active time. The method further includes the device starting a first timer, in response to the detecting, wherein the first timer is set for a first timer value that specifies an amount of time between detecting the transmission and starting a second timer that extends the active time by a second timer value. The first timer value is determined based on one or both of a selected first TTI length from multiple TTI lengths for which the device can be enabled and/or a selected shorter first processing time over a second processing time associated with a TTI length used by the device.

Aspects of the disclosure provide an apparatus for wireless communication. The apparatus includes a transceiver and a processing circuit. The transceiver is configured to transmit and receive wireless signals. The processing circuit is configured to detect an error of a previous scheduled transmission of data units from the apparatus to another apparatus. The other apparatus provides scheduled resources for transmission between the two apparatuses. Further, the processing circuit is configured to determine resources that are scheduled by the other apparatus for the apparatus to perform retransmission, and provide one or more of the data units in the previous scheduled transmission to the transceiver for retransmission using the scheduled resources.

A method and device for transmitting feedback information. The method includes: determining feedback type information and/or delay information when data is transmitted by a network device; and determining a reliability grade of a feedback transmission or that the feedback transmission is exempted at a certain situation, according to the delay information and/or the feedback type information. Therefore, HARQ feedback load may be reduced without impacting HARQ performances.
