    摘要: A method implemented at a user equipment (UE) may include receiving a grant from a base station permitting the user equipment to transmit data to the base station and transmitting data to the base station, where the data includes a buffer status report (BSR) that indicates an amount of data in a buffer of the UE. The method may further include starting or restarting a discontinuous reception (DRX) timer when the data including the BSR is transmitted to the base station. The method may additionally include monitoring (730) a control channel during a duration of the DRX timer. In another implementation, a method may include receiving a feedback message in response to the data transmission including the BSR, and starting or restarting the discontinuous reception (DRX) timer when the feedback message is received. The feedback message may include an acknowledgement (ACK) or a negative acknowledgement (NACK). In a further implementation, a method may include starting a process specific hybrid automatic repeat request (HARQ) round trip time (RTT) timer upon transmission of the data including the BSR, starting a grant timer when the HARQ RTT timer expires, and monitoring the control channel during a duration of the grant timer.

    摘要: The mobile station described herein comprises a transmission buffer, a receiver, a transmitter, and a controller. The controller triggers a scheduling request and buffer status report when data enters the transmission buffer. When the receiver receives a contention-based scheduling grant allocating contention-based uplink resources, the transmitter transmits one or more data packets retrieved from the transmission buffer along with the buffer status report on the contention-based resources to the network station. If one or more data packets remain in the transmission buffer after transmission of the buffer status report on the contention-based resources, the controller maintains the pending status of the buffer status report and the corresponding scheduling request.

    摘要: Methods and arrangements in a first node for requesting a status report from a second node. The first node and the second node are both comprised within a wireless communication system. The status report comprises positive and/or negative acknowledgement of data sent from the first node, to be received by the second node. The methods comprises the steps of: detecting if any data units have been lost during the transmission, generating a status report, based on the made detection concerning lost data units, buffering the generated status report in a buffer, updating the buffered status report when a change concerning lost data units is detected, receiving a trigger for sending a status report to the second node, and transmitting the status report to the second node, as a response to the received trigger.

    摘要: UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n=the number of bits in C/T field.
