Problems solved by technology

When these power control parameter values ​​are different due to different HS-SCCH and HS-SICH, if the UE also uses different power control parameter values ​​for each HS-SCCH and HS-SICH to calculate the power control value, the UE cannot Correctly calculate and implement the power control process

Embodiment 1

[0070] Embodiment 1 (corresponding method 1):

[0071] (1) The high-level signaling sent by the high-level layer on the network side to the UE includes the information unit "HS-SCCHinfo", and the UE can correctly receive and store the configuration information in this information unit;

[0072] (2) This information unit includes an HS-SCCH set configured for the UE by the network side and a corresponding HS-SICH set. The HS-SCCH set includes 1 to 4 HS-SCCHs. Each HS-SCCH and HS-SICH set A HS-SICH one-to-one correspondence; that is,

[0073] 1 HS-SCCH set → {HS-SCCH1, HS-SCCH2, ...}

[0074] 1 HS-SICH set → {HS-SICH1, HS-SICH2, ...}

[0075] ●HS-SCCH1←→HS-SICH1; HS-SCCH2←→HS-SCCH2;...

[0076] ●HS-SCCH set ←→ HS-SICH set

[0077] (3) The network side configures a set of high-speed shared channel power control parameters in this information unit, which is used for the configuration of power control of all HS-SCCH and all HS-SICH of the HS-SCCH set and HS-SICH set of the UE ...

Embodiment 2

[0088] Embodiment 2 (corresponding method 2):

[0089] (1) The high-level signaling sent by the high-level layer on the network side to the UE includes the information unit "HS-SCCHinfo", and the UE can correctly receive and store the configuration information in this information unit;

[0090] (2) This information unit includes an HS-SCCH set configured for the UE by the network side and a corresponding HS-SICH set. The HS-SCCH set includes 1 to 4 HS-SCCHs. Each HS-SCCH and HS-SICH set A HS-SICH one-to-one correspondence; that is,

[0091] ● 1 HS-SCCH set includes {HS-SCCH1, HS-SCCH2, ...}

[0092] ● 1 HS-SICH set includes {HS-SICH1, HS-SICH2, ...}

[0093] ●HS-SCCH1←→HS-SICH1; HS-SCCH2←→HS-SCCH2;...

[0094] ●HS-SCCH set ←→ HS-SICH set

[0095] (3) In this information unit, the network side configures a set of power control parameter values ​​(PRX HS-SICH , TPC step size, Ack-Nack Power Offset and BLER Target). Specifically:

Abstract

The invention discloses a method of distributing high speed shared channel power control parameters in TD-SCDMA system; network side distributes a suit of high speed shared channel power control parameters for all HS-SCCH of user equipment HS-SCCH set and all HS-SICH of corresponding HS-SICH set, the information unit is transmitted to UE via high layer command; UE uses the suit of parameters to control the power of HS-SCCH and HS-SICH. Network side also can provides multi suits of power control parameters, one suit is used in power control of HS-SCCH and HS-SICH after UE receiving the parameters. So, when user equipment UE uses different high speed shared channels in different TTI, the same power parameters used by UE can be guaranteed, the user equipment can calculate and realize the power control cause correctly.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for configuring high-speed shared channel power control parameters in a TD-SCDMA system. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) technology is a technology that provides high-speed downlink data services for multiple users, and is suitable for services such as multimedia and Internet downloading a large amount of information. HSDPA introduces a new transmission channel: High Speed ​​Downlink Shared Channel (HS-DSCH, High Speed ​​Downlink Shared Channel), users share downlink code resources and power resources for time division multiplexing. This structure is suitable for bursty packet data services. In a Time Division Synchronization Code Division Multiple Access (TD-SCDMA, Time Division Synchronization Code Division Multiple Access) system, the downlink physical channel HS-SCCH is used ...
