Example Embodiment

[0034] It should be noted that the reason for the multi-frequency cell is to make better use of common channel radio resources and reduce the interference of co-frequency broadcast channels and DwPTS between different areas. On the air interface, the biggest difference between a multi-frequency cell and a single-frequency cell lies in the RRC layer protocol, while on the air interface physical layer, there is basically no change, and the physical layer only performs corresponding operations according to the RRC configuration. On the RAN side, in multi-carrier and single-carrier cells, the difference in physical layer processing is only whether to configure pilots and common channels at a certain frequency, and the frequency of common measurement is different.

[0035] Therefore, the concept of multi-frequency cell can be limited to the scope of RNC. As a transceiver, Node B does not care whether multiple common control resources use the same common channel, regardless of whether t...

Abstract

The method comprises: setting multi-carrier entity in radio network controller (RNC) supporting single-carrier cell; each multi-carrier cell comprises at least one cell corresponding to one frequency point; setting logical cell corresponding to each frequency point in said multi-carrier cell; the RNC initiates public channel configuration process in at least one logical cell and builds the public channel in the logical cell.

Description

technical field [0001] The invention relates to the technical field of time division multiplexing wideband code division multiple access (TD-SCDMA), in particular to a method for upgrading a single carrier frequency cell to a multi-carrier frequency cell in the TD-SCDMA system. Background technique [0002] The physical channel of TD-SCDMA includes three-layer structure: the first layer is radio frame, the second layer is subframe, and the third layer is time slot. Specifically, the physical channel is composed of several radio frames, and each radio frame is divided into two consecutive subframes, and each subframe includes seven service time slots and three special time slots. As shown in Figure 1, among the seven business time slots, the 0th time slot is fixedly allocated to the downlink, the first time slot is fixedly allocated to the uplink, and the rest of the time slots can be allocated arbitrarily between the uplink and downlink. The three special time slots in the ...
