Problems solved by technology

In a multi-carrier TD-SCDMA system, the TS0 of the main carrier is still used as the downlink broadcast time slot, while the TS0 of the auxiliary carrier is not used temporarily, which results in low spectrum utilization of the auxiliary carrier

Embodiment Construction

[0071] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0072] In the present invention, DL DPCH, HSDPA-related downlink channels (including HS-SCCH and HS-PDSCH), HSUPA-related downlink channels (including E-AGCH and E-HICH) and FPACH are configured on the secondary carrier TS0, and the secondary carrier TS0 transmits information on corresponding channels, thereby improving spectrum utilization.

[0073] The use of the secondary carrier TS0 is not supported in the existing 3GPP standard, therefore, the current RNC, NODEB and UE do not support the use of the secondary carrier TS0.

[0074]As mentioned above, in order to further improve spectrum utilization, channels are configured on the secondary carrier TS0 in the present invention, and the implementation of this configuration requires both the network and the UE to su...

Abstract

The invention provides an information transmission method in a subcarrier time slot (TS) 0, which comprises the following step of: configuring one or any combination of downlink channels related to a DL DPCH and HSDPA (including an HS-SCCH and an HS-PDSCH), downlink channels related to HSUPA (including an E-AGCH and an E-HICH) and an FPACH in the subcarrier TS0 so as to transmit information between a NodeB and user equipment (UE) on the configured corresponding channels. By the method, the channel is configured in the subcarrier TS0 and corresponding data transmission is performed on the configured channel, so that the utilization rate of a frequency spectrum is greatly improved.

Description

technical field [0001] The present invention relates to the technology of TD-SCDMA system, in particular to an information transmission method on auxiliary carrier time slot 0 (TS0). Background technique [0002] The subframe structure of TD-SCDMA is as follows: figure 1 As shown, it includes an uplink pilot time slot (UpPTS), a guard interval (GP), a downlink pilot time slot (DwPTS), and 7 service time slots of TS0-TS6. Among them, TS1~TS6 are ordinary service time slots. According to the different needs of uplink and downlink data transmission, the six ordinary service time slots can be configured as different ratios of uplink and downlink time slots. For example, the ratio of uplink and downlink time slots is 5:1. It indicates that TS1~TS5 are uplink time slots, and TS6 is downlink time slots; if the ratio of uplink and downlink time slots is 4:2, it indicates that TS1~TS4 are uplink time slots, and TS5~TS6 are downlink time slots. In a single-carrier system, TS0 is use...
