Embodiment Construction

[0037] 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.

[0038] In the first embodiment of the present invention, the HS-SCCH-less method is also used for multi-user transmission, that is, in the CPC mode, the network side can send the data of the UE group on the pre-allocated HS-PDSCH channel, The data of each UE in the UE group is also sent. Specifically, the network side pre-configures a certain HS-PDSCH channel and the modulation and coding format used by the HS-PDSCH channel for the UE working in HS-SCCH-less mode, and the data of the UE group where the UE belongs The transmission also uses the same HS-PDSCH channel and the modulation and coding format it uses. When the network side transmits the data of a single UE on the pre-allocated HS-PDSCH channel, a UE-specific CRC check is used for the HS-DSCH (that is, so...

Abstract

The invention relates to a mobile communication technique, discloses a method and a system of multi-user equipment data transmission in mobile communication networks, extends a continuous packet connection mode to the multi-user equipment data reuse transmission and solves the interoperability problem of the multi-user equipment data reuse transmission and the continuous packet connection mode. The method includes that a network side reuses the packet data which have to be sent to the equipment of the users in the group and sends the grouping data on a pre-allocated first channel. The equipment of the users receives the reused packet data from the pre-allocated first channel and judges that whether the packet data include the data of the equipment of the users according to the temporary mark of the user equipment group. If so, the pre-allocated first channel is processed and the de-multiplexing is implemented to obtain the data of the user equipment. The invention still discloses network side equipment and user equipment, which are applied to the data transmission. The data transmission method of the invention can improve the efficiency of wireless resources and increase the system capacity.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and system for multi-user equipment data transmission 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 do...
