Abstract
The embodiment of the invention discloses a method and a device for determining PRACH (physical random access channel) sending power and a method and a device for responding to an UpPCH (uplink pilot channel) message and relates to the technical field of communication. The invention aims to solve the problem that UE (user equipment) has relatively large deviation in open-loop sending power, so that a message sent by the UE through the PRACH cannot be correctly received by a network side base station or relatively large interference to other users is caused in the prior art. The method for determining the PRACH sending power comprises the following steps that: the UE acquires UpPCH power which is actually received by the base station and the PRACH power which is expectedly received by the base station; the UE acquires the UpPCH power path loss value according to the received UpPCH power which is actually received by the base station; and the UE determines the PRACH sending power according to the UpPCH power path loss value and the PRACH power which is expectedly received by the base station. The method and device can improve the PRACH receiving success rate of the base station or reduce relatively large interference to other users.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and device of method and device and response ascending pilot channel message of definite Physical Random Access Channel transmitted power.
Background technology
at TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, the code division multiple access access that time-division is synchronous) in system, UE (User Equipment, subscriber equipment) need access network side group station, at first need UE to determine to send transmitting time and the power of condition code, described condition code is passed through UpPCH (Uplink Pilot Channel, ascending pilot channel) subchannel, at UpPTS (Uplink PilotTime Slot, uplink pilot time slot) or other up on-position of system side base station appointment send to network base station, described UE transmitted power is:
P
UpPch＝L
P-CCPCH+PRX
UpPCHdes+(i-1)Pwr
ramp (1)
Wherein, the P in (1) formula
UpPchSend the transmitting power of condition code for the UpPCH subchannel; L
P-CCPCHMeasured value for the path loss of descending P-CCPCH (Primary Common Control Physical Channel, basic Common Control Physical Channel); PRX
UpPCHdesFor the UpPCH received power that the base station expectation obtains, notify UE by the base station by the mode of broadcasting; I is the number of times that the uplink synchronous of random access sends condition code; Pwr
RampPower back-off increment for the UE uplink synchronous.
The measured value of the path loss of above-described descending P-CCPCH
L
P-CCPCH＝P
P-CCPCH-RSCP
P-CCPCH (2)
Wherein, in (2) formula, P
P-CCPCHSend the transmitting power of P-CCPCH code for the base station, by base station broadcast notice UE, RSCP
P-CCPCHP-CCPCH code power for UE receives is measured by UE self.
Then, the base station sends FPACH (Fast PhysicalAccess Channel, physical access channel) message according to the described condition code that receives to UE; Send the received power PRX of RRC Connection Request (wireless resource control connection request) message on PRACH by this FPACH message informing UE
PRACHdesAnd the base station receives the time location of UpPCH condition code.
Then, UE sends RRC ConnectionRequest message to the base station according to the FPACH message that receives on PRACH.Its transmitted power is as follows:
P
PRACH＝L
P-CCPCH+PRX
PRACHdes+(i
UpPCH-1)Pwr
ramp (3)
Wherein, L
P-CCPCHWith Pwr
RampValue is determined by above-mentioned formula (1); PRX
PRACHdesFor being handed down to UE by FPACH message in the base station.
In realizing process of the present invention, the inventor finds to exist at least in prior art following problem:
A: in prior art, for UpPCH and PRACH, UE all adopts above-mentioned open Loop Power control to carry out message and sends.When there is the relatively large deviation open loop transmit power in described UE, the expectation received power PRX of the UpPCH that arranges due to the base station
UpPCHdesLarger, even UE sends to the power of base station lower by UpPCH, but also reaching the detection level of base station, thereby the base station can correctly receive the information that UpPCH sends and return to response to UE.When it should be noted that the message that sends by PRACH as described UE, because there is larger minus deviation open loop transmit power in this UE itself, the RSCP that UE measures
P-CCPCHAlso can there be minus deviation in precision thereupon, thereby causes L
P-CCPCHThe value minus deviation is lower; Meanwhile, the transmitted power of the UpPCH that arranges due to the base station again is higher, makes UE higher by the access success rate that UpPCH sends message; Make (i
UpPCH-1) Pwr
RampBe worth less, the P that so just causes PRACH to send
PRACHMinus deviation is larger, make UE by PRACH send message can't be correct arrival network side base station, thereby greatly reduce the success rate access at UE Network with Random Multiple Access System side group station.
B: in prior art, for UpPCH and PRACH, UE all adopts above-mentioned open Loop Power control to carry out message and sends.When there is larger overgauge open loop transmit power in described UE, although Node B is correctly received not impact of PRACH, namely on the not impact of random access success rate, but because the transmitted power of PRACH is larger, can cause larger interference to other users of the ascending time slot at PRACH place.Can impact power system capacity.
