Problems solved by technology
[0013] However, the second solution needs to distinguish whether the user is in the soft handover state; at the same time, in the soft handover state, the power control of the DPCH channel accompanied by the HS-DSCH cannot truly reflect the change in the quality of the HS-DSCH service link, which seriously affects the HS - Power control performance of SCCH

Embodiment Construction
[0042] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0043] Such as Figure 4 Shown, is the schematic flow sheet of the present invention, and as can be seen from the figure, the present invention scheme mainly comprises the following steps:
[0044] S1. When the mobile user's HSDPA link changes, configure an HS-SCCH channel and downlink DPCCH pilot power offset P for the mobile useroffset .
[0045] In this solution, the change of the HSDPA link may refer to the establishment of the HSDPA link by the mobile user, or the reconfiguration of the HSDPA link by the mobile user.
[0046] The power offset is related to the spreading factor of the downlink DPCH, is an empirical value, can be obtained through simulation, and can be consistent with the power offset in the non-soft handover area in prior art 2.
[0047] S2. When the NodeB schedules a certain user for the first time after the HSDPA l...

This invention discloses a method for adaptively regulating HS-SCCH power including A, designing a power offset Poffset of the HS-SCCH channel emission power corresponding to the DPCCH pilot domain power when a mobile user HSDPA link is changed, B, obtaining the pilot power PDPCCH, Pilot, on the down DPCCH channel of said mobile user and designing the initial emission power of said mobile user HS-SCCH: P HS-SCCH, Init=P DPCCH, Pilot +P offset, C, designing the regulation volume of the HS-SCCH channel power when dispatching said mobile user for the Nth time based on the ACK / NACK / DTX information fed back by HS-DPCCH, D, adding the regulation volume of the HS-SCCH channel power to its emission power to get the emission power when dispatching said mobile user for the Nth time.
Description
technical field [0001] The invention relates to the communication field, in particular to a method for adaptively adjusting the power of a high-speed shared control channel (HS-SCCH). Background technique [0002] High Speed Downlink Packet Access (HSDPA) is a technology for high-speed data transmission on the downlink of a Wideband Code Division Multiple Access (WCDMA) system. The introduction of HSDPA adds three physical channels, which are high-speed physical downlink shared channel (HS-PDSCH) for transmitting data information in the downlink, high-speed shared control channel (HS-SCCH) for transmitting downlink control information, and transmission of uplink feedback. High Speed Dedicated Physical Control Channel (HS-DPCCH) for information. [0003] Among the above channels, the information transmitted in the HS-SCCH channel is for the correct reception of data in the HS-PDSCH channel, that is, if the user equipment (UE) wants to correctly receive the data on the do...
