Embodiment 1

[0026] figure 1 It is a flowchart of an MPO configuration method according to an embodiment of the present invention. like figure 1 As shown, this embodiment includes:

[0027] Step S102: Set the MPO configuration value for each UE according to the code channel configuration, power parameter configuration, current access number of terminal UEs, and UE capability level.

[0028] In this embodiment, the MPO value is set separately for each UE, which overcomes the defect that all terminals are configured with the same MPO in the prior art, and at the same time, the MPO can be adjusted, which improves the flexibility of the MPO configuration.

Embodiment 2

[0030] figure 2 It is a flowchart of an MPO configuration method according to an embodiment of the present invention. like figure 2 As shown, this embodiment includes:

[0031] Step S202: Obtain code channel configuration and power parameter configuration. The code channel configuration includes the number of HSSCCH and HSDSCH in the cell, and the power parameter configuration includes HSDPA available power and PCPICH pilot power;

[0032] Step S204: Set the MPO calculation value according to the HSDPA available power, the current number of UE accesses, the UE capability level, the number of cell HSSCCHs, and the number of HSDSCHs;

[0033] Step S206: Obtain the maximum value of MPO corresponding to the UE capability level;

[0034] Step S208: Set the MPO configuration value of the UE according to the calculated MPO value and the maximum MPO value.

[0035] In step S202 of this embodiment, there are two ways to obtain the available power of HSDPA: estimate the R99 power ...

Embodiment 3

[0041] The present invention provides three MPO configuration methods, which are described in this embodiment and method embodiments four and five respectively. In this embodiment, the MPO configuration value is specified by the NodeB, and is sent to the RNC through a wireless link establishment response or a reconfiguration preparation response, and then the RNC configures it for the UE through Rb establishment or reconfiguration

[0042] image 3 It is a flow chart of the MPO configuration method in the third embodiment of the method of the present invention. like image 3 As shown, this embodiment includes:

[0043] Step S302: the RNC sends a wireless link establishment or reconfiguration to the NodeB, and executes steps S304 or S306;

[0044] Step S304: The HSDPA scheduler in the NodeB estimates the R99 power at this time according to the digital carrier transmission power and the HSDPA power at the corresponding time; calculate the R99 power by subtracting the maximum ...

Abstract

The present invention discloses a method and equipment for configuring Measure Power Offset (MPO). The method includes: according to the configuration of code channel, the power parameter configuration, the number of currently accessing User Equipments (UEs), and the capability levels of UEs, setting MPO configuration value for each UE respectively. The present invention sets MPO value respectively for each UE, overcomes the defects of setting the same MPO for all terminals in the prior art, and can adjust the MPO at the same time, increasing the flexibility of MPO configuration.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for measuring offset value MPO configuration. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA for short) and the subsequent evolution version of High Speed ​​Packet Access Plus (HSPA+ for short) are the same as the previous Wideband Code Division Multiple Access (WCDMA) , referred to as WCDMA) business, the throughput has been significantly improved. Therefore, how to more effectively use the existing resources of the cell, especially the power resources, to obtain higher HSDPA or HSPA+ throughput is a very critical issue. In HSDPA and HSPA+, for the terminal (User Equipment, referred to as UE) high-speed data channel The power used by the HS-PDSCH is the pilot power plus the measurement offset value (Measure Power Offset, MPO for short). [0003] How to configure MPO reasonably is very important for HSDPA and HSPA+. The previous ...
