The sending method flow chart of the transmitting power control bit that Fig. 1 provides for one embodiment of the invention, as shown in Figure 1, the method comprises:
Step 100, obtains the fixed transmission power being used for sending transmitting power control TPC bit to subscriber equipment, and described fixed transmission power is ensure that described subscriber equipment correctly receives the constant power value of described TPC bit;
In the embodiment of the present invention base station no longer conventionally in the TPC command that will report according to UE dynamically adjust the transmitted power sending TPC command to UE, but before sending TPC bit to UE, first a fixed transmission power is obtained, and send TPC bit with this fixed transmission power to UE, the transmitting power of up channel is adjusted for UE.
In the embodiment of the present invention, not only can adapt in Hetnet or MF scene, other scenes can also be used, this is not construed as limiting.Certainly, the fixed transmission power that base station adopts should meet UE and accurately receive TPC bit in advance, and the obtain manner for fixed transmission power has detailed introduction in subsequent embodiment.
Step 101, sends described TPC bit according to described fixed transmission power to described subscriber equipment.
After base station gets fixed transmission power, just can send TPC bit according to this fixed transmission power to UE, to ensure that UE can according to the transmitting power stating TPC bit adjustment up channel.
The sending method of the transmitting power control bit that the embodiment of the present invention provides, TPC bit is sent to UE by adopting fixed transmission power, the up-downgoing power control that can meet the soft handover area of MF, HetNet and the light auxiliary carrier wave of telescopic universal mobile telecommunications system (Scalable Universal Mobile Telecommunications System, hereinafter referred to as S-UMTS) can be entered smoothly.
In said method embodiment, the mode that base station obtains fixed transmission power can comprise several as follows:
First kind of way: base station obtains transmitted power and the power bias (power offset) of CPICH of Common Pilot Channel (CPICH), and according to the transmitted power of described CPICH and described power bias, acquisition fixed transmission power.Wherein, the transmitted power of described CPICH and described power bias can be radio network controller (RadioNetworkController; Be called for short: after transmitted power RNC) sending to base station, base station to receive the CPICH that RNC sends and power bias, can be multiplied the two the fixed transmission power obtaining and be used for UE transmission TPC bit.Also can calculate by plus-minus the fixed transmission power obtaining and be used for sending TPC bit to UE.
In first kind of way, before acquisition is used for sending the fixed transmission power of described TPC bit to described subscriber equipment, also comprise the instruction of base station receives power control mode, the instruction of this power control mode can be that RNC sends.Base station indicates according to this power control mode, obtains the fixed transmission power being used for sending TPC bit to subscriber equipment.That is, whether base station adopts fixed transmission power to send TPC bit can be decided according to the power control mode instruction of RNC transmission, if instruction adopts the sending mode of the embodiment of the present invention (namely adopting fixed transmission power to send TPC bit), then the base station handling process that embodiment provides according to the method described above sends TPC bit.If instruction adopts other sending mode such as sending mode conventionally to send, base station then send mode conventionally performs.
Further, in first kind of way, the fixed transmission power adopted is not changeless all the time yet, also can adjust according to actual conditions, the channel quality indicator (CQI) that just can send according to UE in the present embodiment carries out the adjustment of transmitted power, specifically comprise: receive the channel quality indicator (CQI) that UE sends, according to this CQI, the power bias of CPICH is adjusted.The present embodiment is biased Modulating Power by Modulating Power and is biased the product with CPICH transmitted power, to realize the adjustment to transmitted power.Again further, the instruction of the present embodiment power control mode can comprise CQI application indication information, base station is according to CQI application indication information, adjust power bias according to CQI, that is according to this CQI application indication information, base station can determine that the CQI whether sent according to UE carries out the adjustment to power bias.
It should be noted, changeless when the fixed transmission power described in various embodiments of the present invention was construed as within a period of time, namely within this period, base station is come to send TPC bit to UE by same transmitted power herein.But the fixed transmission power that base station is used for sending to UE TPC bit is not thick-and-thin, and base station also can adjust this fixed transmission power, the fixed transmission power in a period of time after the adjustment after the adjustment of base station is come to send TPC bit to UE.
The second way: base station receives the channel quality indicator (CQI) that UE sends, and obtain the fixed transmission power for sending TPC bit to UE according to this CQI.In which, the CQI that base station can send according to UE searches a fixed transmission power corresponding to this CQI value in the correspondence that this locality stores is shown.Described correspondence table comprises the corresponding relation of different CQI value and each fixed transmission power, it can certainly be the corresponding one section of CQI value of each fixed transmission power, concrete corresponded manner does not limit, as long as meet the CQI value sent according to UE to find corresponding fixed transmission power.Base station can also calculate fixed transmission power by a computing formula according to CQI.
In the second way, before obtaining and send the fixed transmission power of TPC bit according to CQI to UE, also comprise base station receiving package and indicate containing the power control mode of CQI application indication information.The instruction of this power control mode can be that RNC sends to base station.Base station according to this CQI application indication information, can be searched corresponding table according to CQI and obtains for the fixed transmission power to UE transmission TPC bit.That is, the CQI application indication information that base station can send according to RNC determines whether adopting the second way to obtain fixed transmission power.
The third mode: base station receives the absolute transmission performance number that RNC sends, using this absolute transmission performance number as being used for the fixed transmission power sending TPC bit to UE.In which, base station sends the fixed transmission power of TPC bit and can't help base station decision itself, but determined by RNC, specifically RNC indicates base station using this absolute transmission performance number as fixed transmission power by sending an absolute transmission performance number to base station, and base station just can send TPC bit according to absolute transmission performance number to UE according to instruction after receiving this absolute transmission performance number.
In the third mode, received signal code power (the Received Signal Code Power that RNC can be reported by UE; Be called for short: RSCP) measured value, calculate the transmitted power of base station transmission needed for TPC bit, namely RNC can adjust absolute transmission performance number in real time, and sends to base station.
4th kind of mode: the transmitted power initial value that first base station adopts to pre-set sends TPC bit as fixed transmission power to UE, and the quality of reception of the TPC command that can send according to UE, adjust fixed transmission power.Such as, base station finds that quality of uplink signal crosses that (the such as SNR of up pilot is greater than desired value some dB some times, then thought good), so can think that descending TPC bit of falling is not received by UE, now base station can by improving the transmitted power of TPC bit.In addition, also can be that base station indicates UE to reduce the transmitted power of TPC command always, but not fall always, now also can think that descending TPC bit of falling is not received by UE, just improve the transmitted power of TPC bit.
In addition, base station can also decide the sending mode (namely adopting fixed transmission power to send the sending mode of TPC bit) whether adopting the embodiment of the present invention to provide in its sole discretion, and can't help other network equipments such as RNC and indicate.Acquisition and the adjustment mode of fixed transmission power can see the various embodiments described above.
