Embodiment Construction

[0050] The core of the present invention is to number the frequency points supported by the UE by adding a frequency point indication in the downlink shared control channel HS-SCCH, and notify the UE of the current frequency point it is currently receiving through the HS-SCCH during real-time communication, and finally complete the control information interaction and sending and receiving of data. For the existing single-frequency point UE, since it only works on a single frequency point, the structure of the HS-SCCH can be directly received and processed without modifying the structure of the HS-SCCH. It is not only compatible with the existing HSDPA scheme, but also supports the control of multi-frequency HSDPA.

[0051] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Abstract

A method supporting multifrequency point data-receiving in high speed downlink packet includes distributing frequency point posting used on downlink packet service in current cell and control channel set to UE by network side when user device UE is switched in, sending control information of HS-PDSCH downlink share channel and frequency point index to UE by network side when data is required to be sent to UE by network side, receiving and processing HS-PDSCH data from corresponding frequency point by UE according to received index and control information and relying information on corresponding uplink control channel by UE according to corresponding relation.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for supporting multi-frequency point data reception in high-speed downlink packets. Background technique [0002] HSDPA (High Speed ​​Downlink Packet Access) is a new technology introduced by 3GPP (Third Generation Partnership Project) in Release 5. Using HSDPA can effectively increase the data transmission rate in the downlink direction of packet services and improve the system performance. Frequency Band Utilization. In HSDPA, multiple users share code channel resources. Through AMC (Adaptive Coding and Modulation) and hybrid request retransmission (HARQ) technology, a higher rate is allocated to UEs with good channel environment, and a lower rate is allocated to users with poor channel environment. low rate. HSDPA technology is applicable to WCDMAFDD (Wideband Code Division Multiple Access Frequency Division Duplex), UTRATDD (Universal Terrestrial Radio...
