Abstract

The invention discloses a method for controlling the power of the HSDPA system, which aims at the HS-SICH and includes the steps of: real-time monitoring the corresponding relationship between the HS-SCCH as well as the HS-SICH and UE, and obtaining a time parameter of the corresponding relationship between the channel and the UE; a first stage, which is the stage from the first HS-SCCH subframe transmitted from the base station to the generation of the power control instruction by utilizing the first HS-SICH subframe fed back by the UE, wherein, the power control instruction can be set to be up or down randomly or alternately; a second stage, which is the stage from the generation of the power control instruction by utilizing the first HS-SICH subframe fed back by the UE to the last HS-SCCH subframe transmitted for the UE, wherein, the power control instruction can be set by utilizing the power control parameters obtained from the calculation of the HS-SICH subframe; the base station transmits the HS-SCCH subframe carrying the power control instruction to the UE. The invention also discloses a power control method aiming at the HS-SCCH, a base station and a down beam shaping proposal.

Description

technical field

[0001] The present invention relates to the technical field of high-speed downlink packet access (HSDPA), in particular to a HSDPA system power / synchronous control method, beam forming method and base station equipment. Background technique

[0002] High Speed ​​Downlink Package Access (HSDPA) is a technology proposed in 3GPP R5 to provide high-speed downlink data transmission for multiple users. It is Time Division Synchronous CDMA (TD-SCDMA) ) enhanced version. In the HSDPA technology, three shared physical channels are used to realize the data communication between the base station (Node B) and the user equipment (UE). The three physical channels are High Speed ​​Downlink Shared Control Channel (HS-SCCH), High Speed ​​Uplink Shared Information Channel (HS-SICH) and High Speed ​​Physical Downlink Shared Channel (HS-PDSCH).

[0003] Wherein, HS-SCCH is an HSDPA downlink control channel, which is a physical channel, and it is used to carry all relevant cont...
