Description

UE, network side device, power adjustment method, and SG determination method

The present invention relates to the field of communications technologies, and in particular, to a UE, a network side device, a power adjustment method, and an SG determining method. Background technique

In the second secondary carrier technology, the system introduces a new carrier for the user equipment (UE: User Equipment), which is similar to the dual-carrier high speed uplink packet access (DC-HSUPA: Dual Cell High Speed Uplink Packet Access). The carrier, by setting a higher load target value, all UEs in the system perform time division multiplexing (TDM: Time-Division Multiplexing) on the carrier.

The second secondary carrier technology has the advantage that only one or a few UEs transmit data at the same time, which greatly reduces the multiple access interference between UEs. In addition, since one UE can occupy higher load resources within one Transmission Time Interval (TTI), the UE can perform high-speed data transmission.

Wideband Code Division Multiple Access (WCDMA) uplink UE transmission is performed by scheduling, and the base station is based on the measured signal to noise ratio of the UE's dedicated physical control channel (DPCCH: Dedicated Physical Control Channel). A service grant (SG: Serving Grant) characterizing the maximum power available to the UE is sent to the UE, and the high power indicates that a large block length can be scheduled.

In the traditional mode, before the UE starts to send E-DCH Enhanced: Dedicated Channel data, it will send a DPCCH power control prefix for a period of time for channel quality synchronization. However, in the second secondary carrier technology, when the UE switches, the new UE that is handed over may not have the DPCCH power control prefix, so the base station cannot determine the initial power used by the UE to start transmitting until the base station receives the DPCCH sent by the UE uplink. The signal to interference ratio (SIR: Signal to Interference Ratio) of the DPCCH is estimated, and the power control command word is obtained according to the comparison result of the SIR and the target signal interference ratio ^SIR ^ ^et and transmitted to the UE for receiving by the downlink, and the UE receives the power control command word. The transmit power of the UE is adjusted by the power step included in the power command word.

There are two power step sizes specified in the current protocol. One is to adjust ldB per time slot, and the second is to adjust 2dB per time slot. The power step determined by the method of the prior art may cause the transmission power of the UE to be adjusted too slowly if the power step is too low, thereby causing the UE to transmit power too low, and the available load cannot be fully utilized; If the power step is too high, the load will exceed the target value. That is, there is a technical problem in the prior art that the adjustment of the transmission power of the UE is not accurate enough. Summary of the invention

Compared with the prior art, the power of the DPCCH is adjusted by using only one power step. The present invention can use different power steps to transmit power to the DPCCH for different adjustment stages. The adjustment is performed to further improve the transmission power of the DPCCH, and it can be ensured that the signal to interference ratio (SIR: Signal to Interference Ratio) of the DPCCH determined by the base station can converge to the target signal to interference ratio ^SIRt as soon as possible.

The main implementation principles, specific implementation manners, and the corresponding beneficial effects that can be achieved by the technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In a first aspect, an embodiment of the present invention provides a UE. Referring to FIG. 1, the method specifically includes: a processor 10, configured to determine a first power step.

Dedicating the dedicated physical control channel DPCCH transmit power of the user equipment UE from the initial power to the first transmit power using the first power step;

Determining a second power step that is different from the first power step,

Using the second power step to adjust the DPCCH transmit power from the first transmit power to the second transmit power;

The transmitter 11 is connected to the processor, and is configured to send data to the network side device by using the first sending power and/or the second sending power, that is, may be configured by using the first sending power and the second sending power. At least one type of transmission power transmits data to the network side device.

In a specific implementation, the UE further includes: a receiver, connected to the processor 10, configured to receive a power headroom sent by the network side device before determining the first power step. The network side devices are, for example, a base station, a radio network controller (RNC: Radio Network Controller), and the like.

The processor 10 is further configured to: acquire a reference power, and determine an initial power according to the reference power and the power margin.

The base station cannot determine the initial power of the DPCCH used by the UE when the UE is handed over or when the UE does not transmit data for a long time. Therefore, in the initial transmission phase, the initial power of the appropriate DPCCH needs to be determined for the UE to ensure that no reception is received. Before the AG sent by the network side device can also send data, thereby improving resource utilization.

In a specific implementation process, the network side device may send a power headroom to the UE by using signaling.

The DPCCH in the present invention can configure the primary carrier and the secondary carrier, and the scheme is applied to the dual carrier system. In this case, the reference power is, for example, the current power of the primary carrier or the downlink pilot power of the secondary carrier, and the like. The two types of power can be detected by the UE. The method for obtaining the reference power is not limited in the embodiment of the present invention.

When the current power of the primary carrier is the current uplink power, since the current uplink frequency of the primary carrier and the secondary carrier have a small frequency interval, the UE normally transmits the DPCCH through the secondary carrier, thereby ensuring that the determined initial power of the DPCCH is more accurate. .

The processor 10 can obtain the initial power by linearly calculating the power headroom and the reference power, for example: obtaining the initial power by the following formula:

P _ini = P _ref - power_margin [ 1 ] where P _ini represents the initial power;

P _rc f represents the reference power;

Power—margin represents the power headroom.

Through the foregoing solution, it is ensured that after the UE is switched, or after the UE does not perform data transmission for a period of time, the initial power can be quickly determined without waiting for the network side device to determine the initial power of the UE, and thus can be switched or a segment. After no data transmission in the time, The initial power is quickly determined, thereby achieving the technical effect of making full use of the available network load. The processor 10 can determine the first power step in a plurality of manners. Two of them are described below. Of course, in the specific implementation, the following two situations are not limited.

In the first mode, the receiver is specifically configured to: receive a power control command word sent by the network side device, where the power control command word includes a first power step;

The processor 10 is specifically configured to: acquire a first power step from the receiver.

After the UE determines the initial power, the transmitter 11 transmits the DPCCH to the network side device with the initial power.

After receiving the DPCCH, the network side device estimates the signal to interference ratio of the DPCCH (SIR:

Signal to Interference Ratio), and then compared with the target signal interference ratio ^SIRta ^, and then generate a power control command word for lifting power, and send it to the UE for power adjustment. For example: If the SIR of the DPCCH differs greatly from the ^δΙΚϊ , the network side device determines to use a larger first power step; and if the SIR of the DPCCH is smaller, the network side device determines to use a smaller first power step. Long, etc., this will ensure that the SIR of the DPCCH converges as soon as possible. If the SIR is higher than the S1R, the power control command word for reducing the power is generated. If the SIR is lower than the ^SIRt , the power control command word for increasing the power is generated.

In the second mode, the processor 10 is specifically configured to: determine the quotient value obtained by dividing the absolute value of the power headroom sent by the network side device by n as the first power step size, where η is specifically: the UE first adopts the service authorization. The SG performs the number of delay slots for enhancing the dedicated channel dedicated physical data channel E-DPDCH data transmission.

Generally, a 2 ms transmission time interval (TTI: Transmission Time Interval) is equal to 3 time slots. If the delay of E-DPDCH data transmission includes 5 TTIs and the number of delay slots is 15, then it can be determined. The first power step is: power_margin/15.

Optionally, the receiver may further receive a power control command word sent by the network side device and include a power up and down command, and then determine the first transmit power by using the first power step and the power up and down command, for example: if the power up and down command is Reduce the power indication, then subtract the first power from the initial power The step size is used to obtain the first transmit power; if the power up and down command is an indication of increasing power, the first transmit power is obtained by increasing the first power step by the initial power.

Wherein, if the first power step is sent by the network side device to the UE through the power control command word, the power control command word may include both the first power step and the power up and down command; and if the first power step is The UE side determines that the power control command word only includes the power up and down command.

Optionally, the UE may adjust the initial power by using the first power step, and determine the first transmit power.

Optionally, the receiver is further configured to: receive a power control command word sent by the network side device, where the power control command word includes a second power step size;

The processor 10 is specifically configured to: acquire a second power step from the receiver.

In a specific implementation process, the UE first sends the first sending power to the network side device.

DPCCH; after receiving the DPCCH, the network side device estimates the SIR of the DPCCH, and then compares it with the target signal interference ratio ^SIRt ^t, thereby generating a power control command word for lifting power, wherein if

If the SIR is higher than ^SIRt , a power control command word with reduced power is generated. If the SIR is lower than ^SIRt , a power control command word for increasing power is generated. Finally, the network side device transmits a power control command word including a power up and down command and a second power step to the UE.

After receiving the power control command word including the power lifting command and the second power step, the processor 10 also determines the second sending power by using the power lifting command included in the power control command word, for example: The command is an indication of increasing power, and determining a second transmit power by using a second power step and a first transmit power; and if the power up/down command is an indication of reducing power, reducing the first transmit power by using the second power step The transmission determines the second transmission power and the like.

Similarly, the processor 10 can adjust the first transmit power by using the second power step multiple times to determine the second transmit power. Moreover, since the DPCCH transmission power is adjusted by the second power step, after the DPCCH transmission power is adjusted by the first power step, it is usually a fine adjustment information, so that the second power step is usually smaller than the first power step. For example, the first power step is 2 dB, and the second power step is IdB. System.

As shown in Fig. 2a and Fig. 2b, in Fig. 2a and Fig. 2b, p denotes initial power, step1 denotes a first power step, step 2 denotes a second power step, and step 2 denotes a second power step. The length is less than the first power step indicated by stepl.

2a is a schematic diagram of power adjustment when a power control command word that transmits a first power step and a power control command that sends a second power step both include an increased power indication.

First, the initial power p is determined, and then the transmitter 11 sends the DPCCH to the network side device through the initial power p, and the network side device detects the SIR of the DPCCH, determines that it is smaller than ^{SIRt a} ^t, and the SIR has a large amplitude difference, so the transmission power is increased. The power control command word, which includes stepl, after receiving the power control command word through the receiver, the processor 10 adjusts the DPCCH transmission power from the initial power p to p+step1;

Then, the transmitter 11 of the UE sends the DPCCH to the network side device through p+step1, and the network side device detects the SIR of the DPCCH, and determines that it is smaller than ^{SIRt ar} g ^et , and the SIR and ^SIRta ^ have a large difference, for example: UE side initial power setting Too low, or encountering channel fading is just too large, it will lead to SIR and

The SiR^ _{get has a} large amplitude difference, for example, the SIR is -12dB, and the ^SIRt ^t is, for example, 8dB. Therefore, the power control command word for increasing power is sent, where the step1 is included, and the processor 10 of the UE receives the power control command word through the receiver. After that, the DPCCH transmission power is adjusted from the initial power p to p + 2 X stepl;

Then, the transmitter 11 of the UE sends the DPCCH to the network side device through p+ 2 X step1, and the network side device detects the SIR of the DPCCH, determines that it is smaller than the ^{SIRt ar} g ^et , and the SIR and the SIR ^ar g ^et have a small difference, so the power is The step size is adjusted to step 2 by step1, and then the power control command word for increasing power is transmitted, which includes step2. After receiving the power control command word through the receiver, the processor 10 of the UE adjusts the DPCCH transmission power from the initial power p to p+. 2 X stepl+ step2;

Then, the transmitter 11 of the UE transmits the DPCCH to the network side device through p+ 2 step1+step2, and the network side device detects the SIR of the DPCCH, determines that it is smaller than ^{SIRt a} ^t, and the SIR and ^SIRta ^ have a small difference, for example: if p+ 2 The transmission power of X stepl+ step2 is just right, or the channel is weak. The drop is just small, just so that the SIR fluctuates near the SIRtarget, so that the SIR is just slightly smaller than the S1R^ _g% SIR, for example, 7dB, ^SIRta ^, for example, 8dB, so continue to send the power control command word with increased power, including step2, After receiving the power control command word through the receiver, the processor 10 of the UE adjusts the DPCCH transmission power from the initial power p to p+ 2 X step 1+2 step2; and so on.

FIG. 2b is a schematic diagram of power adjustment when the power control command word for transmitting the first power step and the power control command word for transmitting the second power step include the power reduction indication.

First, the initial power p is determined, and then the transmitter 11 of the UE transmits the DPCCH to the network side device through the initial power p, and the network side device detects the SIR of the DPCCH to determine that it is larger than ^SIRt ^t, and the SIR and the SIR^ have a large difference, so Sending a power control command word with reduced power, including step1, after receiving the power control command word by the receiver, the processor 10 of the UE adjusts the DPCCH transmission power from the initial power p to p-stepl;

Then, the transmitter 11 of the UE sends the DPCCH to the network side device through the P-step1, and the network side device detects the SIR of the DPCCH, and determines that it is larger than the ^{SIRt ar} g ^et , and the SIR and the ^SIRta ^ have a large difference, for example, the initial power setting on the UE side. If the SIR is too large, the SIR determined by the network side device is larger than the ^SIRta ^. The SIR is, for example, 15 dB, and the ^{SIRt is,} for example, 2 dB. Therefore, the power control command word of the reduced power is sent, including the step1, and the processor 10 of the UE is passing. After receiving the power control command word, the receiver adjusts the DPCCH transmission power from the initial power p to P- 2 X stepl;

Then, the transmitter 10 of the UE sends the DPCCH to the network side device through the P-2 step1, and the network side device detects the SIR of the DPCCH, determines that it is larger than the ^SIRtar g ^et , and the SIR and the ^SIRtar g ^et have a small difference, so the power step is Adjusted by step1 to step2, and then send a power-down command word with reduced power, including step2, after receiving the power control command word through the receiver, the processor 10 of the UE adjusts the DPCCH transmission power from the initial power p to P-2. X stepl-step2;

Then, the transmitter 11 of the UE transmits the DPCCH to the network side device through P-2X step1-step2, and the network side device detects the SIR of the DPCCH, which is determined to be larger than ^{SIRt ar} g ^et , and the SIR is different from the ^SIRtar g ^et The amplitude is small, for example: transmit power P-2 X step1-step2 transmit power just right, or channel fading is not large, in this case, SIR may be slightly larger than ^SIRt ^, SIR is, for example: 3dB, ^SIRt ^ : 2dB, so continue to send the power control command word with reduced power, including step2, after receiving the power control command word through the receiver, the processor 10 of the UE adjusts the DPCCH transmission power from the initial power p to p. 2 X step 1-2 χ step2, and so on.

The second aspect is based on the description of the embodiment of the first aspect. The embodiment of the present invention provides a network side device. Referring to FIG. 3, the following specifically includes:

The processor 30 is configured to determine a power control command word including a power lifting instruction;

The power is adjusted from the initial power to the first transmit power;

The processor 30 is further configured to: determine a power control command word that includes a second power step;

The transmitter 31 is further configured to: send the power control command word that includes the second power step to the user equipment UE, so that the UE adjusts the first sending power to the second sending power by using the second power step, where One power step and the second power step are different power steps.

Optionally, the processor 30 is further configured to determine a first power step size;

The transmitter is further configured to: send the power control command word including the first power step and the power up and down command to the UE, so that the UE adjusts the DPCCH transmit power from the initial power to the first transmit power by using the first power step.

In a third aspect, based on the description of the first embodiment, the embodiment of the present invention provides a user equipment UE. Referring to FIG. 4, the method includes:

The receiver 40 is configured to receive a target signal to interference ratio ^SIRt ^t transmitted by the network side device and a total control channel power margin C/P available to the UE;

The processor 41 is connected to the receiver 40 for determining the SG according to at least the ^SIRt and the C/P.

As shown in FIG. 5, a dedicated physical data channel (E-AGCH: E-DCH Dedicated Physical Data Channel) for enhancing the dedicated channel (E-DCH: Enhanced Dedicated Channel) is transmitted. The timing relationship diagram of the sending and the application, after the UE3 is switched to the UE1, the first absolute grant (AG: Absolute grant) sent by the network side device is delayed after a period of time (as shown in FIG. 5 is 5 ΤΉ), that is, The second #0 ΤΉ can take effect. The AG usually refers to the SG carried on the E-AGCH channel, and the SG characterizes the maximum power available to the UE.

Therefore, in the initial transmission phase, the initial power of the appropriate E-DPDCH needs to be determined for the UE to ensure that the data can be sent before the SG sent by the network side device is received, thereby improving resource utilization.

And in the above solution, the SG used for initial transmission of the E-DCH dedicated physical data channel (E-DPDCH: E-DCH Dedicated Physical Data Channel E-DCH dedicated physical data channel) can be determined on the UE side, so that the UE can be guaranteed. The transmission does not exceed the load target of the network, and the processing load of the network side device is reduced.

In the specific implementation process, the SIR _target is the demodulation error block rate of the RNC statistical E-DPDCH data, and is determined according to a certain outer loop power control algorithm, for example, counting the block error rate of the previous period. Comparing the statistical block error rate with the block error rate target value, if the value is greater than the target value, the SIR _{target is} down-regulated to a smaller value, and if less than the target value, the SIRt^et is adjusted to a larger value. The C/P is set directly by the network.

Optionally, the network side device may send the ^SIRt t and the C/P to the UE by using the high layer signaling.

Optionally, the processor 41 may represent a correspondence between SG and ^SIRtar g ^et and C/P by the following formula, where function represents a function (function has the same meaning in the following formula): SG=function (SIR^ , C / P) [2] In the specific implementation process, the processor 11 determines the SG according to at least the ^SIRt and the C/P, and can be divided into a plurality of cases. The following two examples are introduced, of course, in the specific implementation process. , not limited to the following two cases.

The first way:

The receiver 10 is further configured to: receive the UE that is sent by the network side device before determining the SG according to at least the ^SIRt and the C/P Load with the network load.

The available network load load is, for example, the UE available signal energy ratio noise energy, the base station air interface total energy ratio noise energy (ROT: rise to thermal), and the like, wherein if the network side device directly transmits to the UE, the UE can use the signal energy ratio noise. The energy can be used directly in subsequent calculations. If the network side device sends other parameters related to the noise energy of the UE than the noise energy, such as ROT, it needs to be converted into UE available signal energy than noise energy.

In this case, the processor 41 is specifically configured to:

Determine the SG based on at least ^SIR ^ ^et , C/P, and Load. That is, the correspondence between SG and SIR^, _C/ p, and _Load can be expressed by the following formula:

SG=function( ^SIRt , C/P, Load) [3] The processor 41 can be divided into at least two cases when determining the SG according to ^SIRtar , C/P and Load, which are respectively introduced below.

The processor 41 determines the SG only by ^SIRt ^t C/P and Load. For example, the SG can be further determined by the following formula:

In the above formula, the SG determined by taking the equal sign is a better SG, which can ensure sufficient use of the network load and ensure that the network load does not exceed the available network load of the UE.

2 Receiver 40, also used to:

In this case, the processor 41 determines the SG according to ^SIRta ^, Load, C/P, and power_margin, that is, the relationship ^between SG and ^SIRtar g ^et , C/P, Load, and power-margin can be expressed by the following formula. Correspondence:

SG=function ( ^SIRtarget , C/P, Load, power—margin ) [5] As a first embodiment of the formula [5], the processor 41 can be further calculated by the following formula _: determining the SG:

,

The above calculation formula is generally applied to UEs that perform data transmission through a single antenna, thereby achieving that in a single antenna system, it is ensured that the UE's transmission does not exceed the network load target, and the processing load of the network side device is reduced.

As a second embodiment of the formula [5], the processor 41 can further calculate the SG by the following formula:

SIRt arg et . C, . SIRt arg et .

256 ― P 256 ―

[7] The above calculation formula is usually applied to UEs that transmit data through multiple antennas, compared to the formula

[6] In terms of the power overhead of the pilot channel, one of the differences between multiple antennas and single antennas is that multiple antennas need to transmit one more pilot channel.

In the specific implementation process, the SG can be further determined by the following formula:

SG, that is, the correspondence between SG and ^SIR ^ ^et , C/P and η can be characterized by the following formula:

SG=function ( ^Sn , c/P, η ) [9] While the processor 41 determines the SG according to ^SIR ^ ^et , C/P, and η, it can be divided into at least two cases, which are respectively described below. The 1 processor 41 determines the SG based only on C/P, η, for example, by the following formula

The processor 41 is specifically configured to: determine the SG based on ^SIRt , C/P, η, and ^power_margin , that is, the correspondence between the SG and the ^SIRt , C/P, η, and ^power_margin can be characterized by the following formula:

SG=function ( ^SIRtarget , C/P, η, power—margin ) [11] As a first embodiment of the formula [11], the processor 41 can further determine the SG by the following formula:
