Embodiment Construction

[0034] Please refer to FIG. 1 , which is a flow chart of the method of the technical solution of the present invention. The technical solution includes the following steps:

[0035] Step 101, for the existing F-DPCH physical channel, divide a time slot according to 256 chips, which can be divided into 10 multiplexing boundary numbers;

[0036] Step 102, when the user needs to allocate F-DPCH physical channel resources, first determine the default dedicated physical channel offset value (Default DPCH Offset Value) for it;

[0037] Step 103, calculate the timing deviation (F-DPCH Frame Offset) of F-DPCH relative to P-CCPCH according to Default DPCH Offset Value;

[0038] Step 104, determine the multiplexing boundary according to the F-DPCH Frame Offset;

[0039]Step 105, adjust the Default DPCH Offset Value according to the determined multiplexing boundary value, and recalculate the F-DPCH Frame Offset.

[0040] In the above step 101, the multiplexing boundary number can be 0...

Abstract

The present invention discloses a method for reusing the frictional dedicated physical channel to realize that a plurality of users reuses one F-DPCH, and the method comprises the steps of: step one, dividing the reusing boundary of the existent frictional dedicated physical channel and confirming the deviation value of the default dedicated physical channel; step two, calculating the timing deviation of the frictional dedicated physical channel relative to the main common control physical channel according to the deviation value of the default dedicated physical channel; step three, confirming the reusing boundary value according to the timing deviation of the frictional dedicated physical channel relative to the main common control physical channel; and step four, adjusting the deviation value of the default dedicated physical channel according to the reusing boundary value, then calculating the timing deviation of the frictional dedicated physical channel relative to the main common control physical channel according to the deviation value of the adjusted default dedicated physical channel. The invention staggers the F-DPCH which is shared by a plurality of users by time to realize that a plurality of users reuses one frictional dedicated physical channel.

Description

technical field [0001] The invention relates to a dedicated physical channel multiplexing technology in a mobile communication system, in particular to a multiplexing method of a fractional dedicated physical channel (Fraction-Dedicated Physical Channel, F-DPCH). Background technique [0002] The R99 standard protocol of the WCDMA (Wide Code Division Multiple Access) mobile communication system provides users with a maximum rate of 384 kbps, and hot spots can provide a rate of 2 Mbps. From the perspective of the performance of the Dedicated Channel (DCH) and Downlink Shared Channel (DSCH) that R99 can support for transmitting packet data, for users in general areas, the rate bandwidth provided by R99 will not be able to meet The needs of users in hotspot areas; therefore, the R5 standard protocol introduces the High Speed ​​Downlink Packet Access (HSDPA) function, and at the same time introduces a high-speed packet shared transmission channel (HighSpeed ​​Downlink Shared Cha...
