Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.

Fig. 1 is for strengthening the embodiment 1 of the physical channel Poewr control method that high speed shared channels is relevant under the connection mode common condition.

Step 110, subscriber equipment are passed through cell update request message, wireless resource control connection request message or measurement report message to its measurement result to CPICH Common Pilot Channel of wireless network controller reporting;

Measurement result to CPICH Common Pilot Channel is: the reception signal strength signal intensity (RSCP) of signal interference ratio of CPICH Common Pilot Channel (Ec/N0) or CPICH Common Pilot Channel or path loss (pathloss).

Step 120; When the data that need transmit subscriber equipment when radio network controller are given the base station; Calculate HS-SCCH and HS-PDSCH (1 or many) spendable transmit power level when transmitting these data according to the size of the measurement report values of user equipment to report, media access control protocol data unit, and in the Frame of high speed descending sharing channel, carry transmit power level and send to the base station;

Said transmit power level correctly receives the deviation of needed minimum emissive power of data and above-mentioned maximum transmission power for the present present position of user; In other words, just user's current location with respect to the deviation that correctly receives the needed transmitting power of data at cell edge.Subscriber equipment is more little from the near more needed transmitting power in base station, and the transmit power level that obtains thus is a negative value, and when subscriber equipment was in cell edge, this transmit power level then got zero.

Radio network controller can be confirmed transmit power level through following method; But be not limited to this: through subscriber equipment at the measurement report that inserts the CPICH Common Pilot Channel that reports radio network controller on the transmission channel at random; Such as the signal interference ratio (CPICH_Ec/N0) of CPICH Common Pilot Channel or the reception signal strength signal intensity (RSCP) or the path loss (pathloss) of CPICH Common Pilot Channel, and the size of media access control protocol data unit is confirmed the needed transmit power level of this data cell.When the signal interference ratio of CPICH Common Pilot Channel big more, perhaps when the reception signal strength signal intensity of CPICH Common Pilot Channel strong more, show that subscriber equipment is near more apart from the base station, then this moment, needed transmit power level was more little; When path loss is big more, explain that subscriber equipment is far away more apart from the base station, perhaps the size when media access control protocol data unit is big more, and then this moment, needed transmit power level was also big more.In addition, transmit power level also has relation with processing gain, and the processing gain of HS-PDSCH and HS-SCCH is big more, and transmit power level is more little.

Described transmit power level is used for confirming total transmitting power of HS-SCCH and one or more HS-PDSCH, is example with the path loss, and the computational methods of transmit power level (TPL) are following:

$\mathrm{TPL}=2(L+[N_T+(1-\mathrm{\γ}+i)\×\mathrm{Load}/L-\mathrm{CpichPower}])-\mathrm{PG}1-\mathrm{PG}2+\frac{E_b}{N_{\mathrm{O\; hspdsch}}}+\frac{E_b}{N_{\mathrm{O\; hsscch}}}$

Wherein: L is the path loss of user equipment to report, N _TBe noise power, γ is a nonorthogonal factor, and i is the interference factor of neighbor cell, and Load is the load of current area, E _b/ N _oBe signal interference ratio, PG1 is the processing gain of HS-PDSCH physical channel, PG1=W/R (ratio of bandwidth and service rate), wherein, W=3.84M, Round in the expression, PG2 is the processing gain of HS-SCCH physical channel, and PG2=W/128, MacPduSize are the sizes of protocol Data Unit relevant in the Frame, and CpichPower is the transmitting power of CPICH Common Pilot Channel.

Step 130; When the base station sends data to subscriber equipment; Distribute to total transmitting power of HS-SCCH and HS-PDSCH according to the transmit power level size decision of media access control protocol data unit; Distribute to the power division ratio of HS-SCCH and HS-PDSCHs then according to HS-SCCH and HS-PDSCH institute data carried by data bit, spreading gain, significance level decision; Thereby finally confirm the transmitting power of HS-SCCH and HS-PDSCHs, the base station uses the transmitting power of confirming on HS-SCCH and HS-PDSCH, to send signaling and/or data respectively.

Concrete computational methods are following, but are not limited to this:

Total transmitting power of HS-SCCH and HS-PDSCHs:

TransmitPowerforHs＝TPL+CpichPower

The base station is following according to the transmitting power ratio method of TransmitPowerforHs decision HS-SCCH and HS-PDSCH:

$\frac{\mathrm{TransimtPowerforHsscch}}{\mathrm{TransimtPowerforHsPdsch}}=\frac{1}{N}\×\frac{16}{128}\×\mathrm{\α}$

Wherein: N is a HS-PDSCH physical channel bar number; If modulation system is QPSK; Then

is if modulation system is 16QAM; Then

wherein; MachsPduSize is the protocol Data Unit size that MAC-hs will send, and 16 is the spreading factor of HS-PDSCH; 128 is the spreading factor of HS-SCCH, and α is the significance level weight, more than or equal to 1.

It is thus clear that when HS-PDSCH has only one, and weight equals at 1 o'clock, HS-SCCH is the ratio of the spreading factor of the two with the power division ratio of HS-PDSCH.

Fig. 2 is for strengthening the embodiment 2 of the physical channel Poewr control method that high speed shared channels is relevant under the connection mode common condition.

Step 210, subscriber equipment are passed through cell update request message, wireless resource control connection request message or measurement report message to its measurement result to CPICH Common Pilot Channel of wireless network controller reporting;

Measurement result to CPICH Common Pilot Channel is: the reception signal strength signal intensity (RSCP) of signal interference ratio of CPICH Common Pilot Channel (Ec/N0) or CPICH Common Pilot Channel or path loss (pathloss).

Step 220; When the data that need transmit subscriber equipment when radio network controller are given the base station; Size according to the measurement report values of reporting of user, media access control protocol data unit is calculated the spendable transmit power level of HS-PDSCHs, and in the Frame at high speed descending sharing channel, carries transmit power level and send to the base station;

When described transmit power level was used for confirming the total transmitting power of one or more HS-PDSCH, the computational methods of transmit power level (TPL) were following:

$\mathrm{TPL}=L+[N_T+(1-\mathrm{\γ}+i)\×\mathrm{Load}/L]-\mathrm{PG}+\frac{E_b}{N_{\mathrm{O\; hspdsch}}}-\mathrm{CpichPower}$

Wherein: L is the path loss of user equipment to report, N _TBe noise power, γ is a nonorthogonal factor, and i is the interference factor of neighbor cell, and Load is the load of current area, E _b/ N _oBe signal interference ratio, PG is the processing gain of HS-PDSCH channel, and PG equals the ratio W/R of bandwidth and service rate, wherein, and W=3.84M,

Round in the expression, MacPduSize is the size of protocol Data Unit relevant in the Frame, and CpichPower is the transmitting power of CPICH Common Pilot Channel.

Step 230; When the base station sends data to subscriber equipment; Distribute to the transmitting power of HS-PDSCHs according to the transmit power level size decision of media access control protocol data unit; Distribute to the power division ratio of HS-SCCH and HS-PDSCHs then according to HS-SCCH and HS-PDSCH institute data carried by data bit, spreading gain, significance level decision; Thereby confirm the transmitting power of HS-SCCH, the base station use the transmitting power of confirming on HS-SCCH and HS-PDSCH, send respectively signaling and/data.

The transmitting power of HS-PDSCHs is distributed in the base station according to the transmit power level size decision of media access control protocol data unit; Distribute to the power division ratio of HS-SCCH and HS-PDSCHs according to HS-SCCH and HS-PDSCH institute data carried by data bit, spreading gain, significance level decision then, thereby confirm the transmitting power of HS-SCCH.

Concrete computational methods are following, but are not limited to this:

Total transmitting power TransmitPowerforHspdsch=TPL+CpichPower base station of HS-PDSCHs determines the transmitting power of HS-SCCH according to TransmitPowerforHspdsch:

$\frac{\mathrm{TransimtPowerforHsscch}}{\mathrm{TransimtPowerforHsPdsch}}=\frac{1}{N}\×\frac{16}{128}\×\mathrm{\α}$

Wherein: N is a HS-PDSCH physical channel bar number; If modulation system is QPSK; Then

is if modulation system is 16QAM, and then

MachsPduSize is the protocol Data Unit size that MAC-hs will send.

If in a Transmission Time Interval of the medium access control entity (MAC-hs) of high speed descending sharing channel, having the data block of a plurality of MAC-c/sh/m to be multiplexed in the media access control protocol data unit is sent out; Then the transmitting power of HS-SCCH is got the maximum of a plurality of data blocks; HS-PDSCH gets the transmitting power sum of these a plurality of data blocks, and the transmitting power sum of HS-SCCH and HS-PDSCHs can not surpass the relevant spendable maximum transmission power of physical channel of high speed descending sharing channel.

For a MAC-hs pdu, a Transmission Time Interval only needs a HS-SCCH, and HS-PDSCH can be one or many at a Transmission Time Interval.If HS-PDSCH is many, then can on the transmitting power basis of confirming, mean allocation arrive every physical channel.

The invention provides a kind of relevant physical channel Poewr control method of high speed descending sharing channel under the connection mode common condition of strengthening; So that the base station can use suitable power to send for being in when the subscriber equipment of strengthening under the connection mode common condition sends data, guarantee the correct reception of subscriber equipment and the capacity of raising system.
