Problems solved by technology

[0011] In practical applications, the above solution has the following problems: additional power consumption of the UE and unnecessary consumption of radio resources
This will increase UE unnecessary receiving operations, thereby increasing UE power consumption
Moreover, in the process of receiving and processing data that does not need to be received by the UE, when the cyclic redundancy check (Cyclic Redundancy Check, "CRC" for short) fails, the UE will still send NACK (no confirmation) , notify NodeB to retransmit, resulting in unnecessary consumption of wireless resources

Embodiment Construction

[0044] 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.

[0045] In the embodiment of the present invention, multiple UE data multiplexing transmission is performed through HSDPA. First, at least two UEs are set as a UE group, and a group identifier is assigned to them; then, the network side will need to send the grouping to each UE in the UE group After the data is multiplexed, it is sent on the first channel, and a temporary identifier is set on the corresponding second channel. The first part of the temporary identifier is the group identifier of the UE group, and the second part indicates whether each UE in the UE group has Data transmission, as shown in Figure 2; after that, the UE receives the temporary identifier from the second channel, judges whether the first part of the temporary identifier is the group identi...

Abstract

This invention relates to mobile communications technology, discloses communications network equipment in multi-user data multiplexing transmission methods and systems, a number of UE makes data reuse in the HS-PDSCH in a TTI, can reduce the processing burden and UE on the Node B Retransmission demand. This invention, the UE organization, in to group data issued after multiplexing, divided temporarily logo, into two parts, the first part of the group that UE logo, and the second part of each group said UE whether there is a data transmission; the group UE analysis the received H-RNTI only when there are data of their own transmissed they could receiver the suit able data from the shared access when there are such data the group UE with go farther to check whether the data is the retransmits one, it will receive it when it is ,if not, it won't receive it.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to data multiplexing of multi-user equipment in a mobile communication network. Background technique [0002] The third-generation Universal Mobile Telecommunications System (UMTS) is favored due to its powerful multimedia communication capabilities, high-speed data transmission rate and efficient spectrum utilization and many other advantages, 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 RepeatreQuest, referred to as "HARQ"), and a series of key technologies such as fast scheduling of base station nodes (Node B), realize downlink high-speed dat...
