Problems solved by technology

[0038] When adopting the scheme of cascading transmission of MAC-hs PDUs of multiple priority queues, there is currently no effective mechanism to ensure that the transmitted MAC-hs PDUs of multiple different priority queues can still be ordered in the reordering queue of the receiving end take over

Embodiment Construction

[0113] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0114] In the present invention, when the UE successfully receives the data from the network side, it judges whether the data belongs to the multiplexed PDU formed by cascading MAC-hs PDUs in at least two priority queues of the same UE, or whether it belongs to the same priority queue In the MAC-hs PDU, and respectively do the corresponding reception processing.

[0115] After the multiplexed PDU is successfully received by the UE, the MAC-hs PDU of the queue with higher priority and smaller sending / receiving window may have been "outdated" for a long time, so the received TSN of the MAC-hsPDU will be different from the current The TSN of the receiving window produces ambiguity (the MAC-hsPDU of the single priority queue does not produce ambiguity). If the TSN of...

Abstract

The invention relates to data receiving method for MAC-hs PDU, wherein when receiving PDU successfully, UE decides the validity of every MAC-hs PDU in the multiplex PDU according to mobile state and position of receiving window of reordered sequence during the transmission. Besides, it also makes prescription for the time that NS stops the re-transmitting of multiplex PDU, which refers to that the desired MAC-hs PDU is stopped.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a high-speed downlink packet access (High Speed ​​Downlink Packet Access, referred to as "HSDPA") technology. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP"), as an important organization in the field of mobile communications, has promoted the standardization of the 3rd Generation Mobile Communications (The Third Generation, referred to as "3G") technology. Its early protocol Both uplink and downlink services in this version are carried on dedicated channels. [0003] With the development of mobile communication technology, 3G technology is also constantly evolving. High Speed ​​Downlink Packet Access (HSDPA for short) and High Speed ​​Uplink Packet Access (HSUPA for short) are important evolutions of 3G technology. Scheduling and retransmission of data packets in HSDPA and HSUPA are con...
