Problems solved by technology

At this time, if there are other idle HS-PDSCH channel codes in the cell, since the RNC cannot dynamically indicate these idle HS-PDSCH channel codes to the Node B through physical shared channel reconfiguration signaling, the Node B still cannot These idle HS-PDSCH channel codes are allocated to UE
Therefore, the existing method for allocating HS-PDSCH channel codes greatly reduces the utilization rate of HS-PDSCH channel code resources

Embodiment Construction

[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with examples.

[0050] The basic idea of ​​the present invention is: configure the physical shared channel reconfiguration signaling interface, so that the interface has the ability to carry at least one group of available HS-PDSCH channel codes, and then RNC passes at least one group of available HS-PDSCH channel code groups The physical shared channel reconfiguration signaling indicates to the Node B, so that the Node B can reasonably and dynamically allocate the HS-PDSCH channel codes for the UE from at least one group of available HS-PDSCH channel code groups. Specifically, if no HS-PDSCH channel code groups are available, zero groups are allocated.

[0051] The method for allocating HS-PDSCH channel codes in the present invention will be described in detail below in conjunction with the emb...

Abstract

The invention discloses a method and system for allocating high speed physical downlink shared channel (HS-PDSCH) codes, where the method configures a physical shared channel reallocation signaling interface with an ability of carrying at least a group of HS-PDSCH codes and also comprises: A. a radio network controller (RNC) determines available HS-PDSCH code groups and reallocates signaling indication through physical shared channel to a Node B; and B. the Node B makes UE allocation according to the obtained HS-PDSCH code; and the system comprises control indication module in RNC and allocation module in Node B. And it can raise utilization ratio of channel code resources and making the HS-PDSCH channel codes flexibly used.

Description

technical field [0001] The invention relates to the technical field of high-speed downlink packet access (HSDPA), in particular to a method and system for allocating high-speed physical downlink shared channel (HS-PDSCH) codes. Background technique [0002] HSDPA technology is an important feature of Wideband Code Division Multiple Access (WCDMA) network R5 version. HSDPA technology realizes high-speed data transmission on the downlink through key technologies such as Adaptive Modulation and Coding (AMC), Hybrid Automatic Repeat Request (HARQ), and Fast Packet Scheduling (FPS). [0003] In HSDPA technology, a high-speed downlink shared channel (HS-DSCH) that can be switched between users at intervals of 2 ms can be provided. In order to realize HS-DSCH transmission, HSDPA introduces three new physical channels. Among them, the high-speed shared control channel (HS-SCCH) and the high-speed dedicated physical control channel (HS-DPCCH) are used for control, and the HS-PDSCH i...
