Embodiment Construction

[0037] As described in the background, in the prior art, the base station cannot know whether the UE has correctly received the HS-SCCH sent by the base station. Therefore, the base station cannot accurately judge the error probability of the HS-SICH reported by the terminal equipment, thus , and cannot accurately perform optimal power control, resulting in performance loss in the system.

[0038] In order to solve the above problems, the embodiment of the present invention provides a structural scheme of the HS-SICH channel, which can solve how to accurately calculate the error probability of the HS-SICH and the error probability of the HS-SCCH at the base station in the HSDPA system.

[0039] Such as figure 2 As shown, it is a schematic flowchart of a method for transmitting HS-SICH information proposed by an embodiment of the present invention, which specifically includes the following steps:

[0040]Step S201, the base station determines the error probabilities of HS-SCC...

Abstract

The embodiment of the invention discloses a transmission method and a device of HS-SICH information. By applying the technical scheme of the transmission method and the device of the HS-SICH information, recommended modulation fashion (RMF) information is removed from the HS-SICH information fed back by a terminal device, and an HS-SICH information loss mark is added. A base station can judge the quality of an information channel simply according to recommended transport block size (RTBS) reported by the terminal device, so that feedback of the RMF can be omitted, the added HS-SICH information loss mark enables the base station to accurately judge error probability of HS-SICH and HS-SCCH, and accordingly the base station can perform optimized power control according to statistical results of corresponding error probability.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and equipment for transmitting HS-SICH information. Background technique [0002] High Speed ​​Shared Information Channel (HS-SICH) is an uplink control channel shared by TD-HSDPA (Time Division-High Speed ​​Downlink Packet Access, time-division synchronous high-speed downlink packet access), and it is also a physical channel. Feedback related uplink information. It mainly includes ACK / NACK (Acknowledgment / NegativeAcknowledgment, confirmation character / rejection character) and channel quality indication CQI (Channel Quality Indication, channel quality indication). [0003] The CQI includes a recommended modulation format (Recommended Modulation Format, RMF) and a recommended transport block size (Recommended Transport Block Size, RTBS). [0004] Such as figure 1 Shown is a schematic diagram of the structure and decoding scheme of the HS-SICH channel in the prio...
