Problems solved by technology

[0020] In practical application, the above solution has the following problems: When transmitting VoIP and other medium-low rate small packet services based on HSDPA, the utilization rate of wireless resources is low
[0021] The main reason for this situation is that in the prior art, HSDPA can only transmit packet data in one MAC-hs priority queue in one UE in one TTI, and the total peak rate of VoIP services based on HSDPA is low. If different packet

Embodiment Construction

[0042] 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.

[0043] The core of the method for transmitting packet data in HSDPA in the present invention is that at first, at least two UEs are set as a UE group, and a group identifier is assigned to them; after that, the network side transmits packets to be sent by different UEs in the same UE group Data multiplexing is sent in one MAC-hs PDU, and the group ID of the UE group is set for the MAC-hs PDU; then, each UE receives the corresponding MAC-hs PDU according to the group ID of the UE group to which it belongs, and unpacks it. After multiplexing, the packet data belonging to the UE is obtained therefrom.

[0044] The system and method for transmitting packet data in HSDPA according to the first embodiment of the present invention will be described below.

[0045] The t...

Abstract

The invention can make the small packet used in VoIP low rate transmission in HSDPA capable of effectively utilizing the radio network resources. In the invention, multi UEs are set into one UE group, and a H-TNTI is allocated to each group; multiplexing the data of multi UEs in the group into one MAC-hs PDU which is send out; according to H-RNTI of group where the UE locates at, the UE gets the MAC-hs PDU, and resolves its own packet data; further, the packet data in different priority queues of same UE can be multiplexed into one MAC-hs PDU to transmit.

Description

technical field [0001] The invention relates to a high-speed downlink packet access technology, in particular to the transmission of packet data in the high-speed downlink packet access. Background technique [0002] The third-generation mobile communication system UMTS (Universal Mobile Telecommunication System, Universal Mobile Communication System) system is favored due to its powerful multimedia communication capabilities, high-speed data transmission rate and efficient spectrum utilization, and has become the future mobile communication system. development goals. One of the important features of the R5 version of UMTS technology is High Speed ​​Downlink Packet Access (High Speed ​​Downlink Packet Access, referred to as "HSDPA"), that is, through adaptive modulation and coding (Adaptive Modulation and Coding, referred to as "AMC"), hybrid retransmission (Hybrid Automatic-Repeat-reQuest, referred to as "HARQ"), and a series of key technologies such as fast scheduling of ...
