Description

The present invention claims to be submitted to the Chinese Patent Office on March 17, 2014, and the application number is PCT/CN2014/073541, and the invention name is UE, network side equipment, power adjustment method and The priority of the PCT International Patent Application for the SG Determination Method, the entire contents of which is incorporated herein by reference. Technical field

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 is a user equipment (UE: User Equipment)? I enter a new carrier, which is similar to the secondary carrier of DC-HSUPA (Dual Cell High Speed Uplink Packet Access). By setting a higher load target value, all UEs in the system are in the system. Time division multiplexing (TDM: Time-Division Multiplexing).

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 signal (DPCCH: Dedicated Physical Control Channel). Sending a service grant (SG: Serving Grant) that indicates the maximum power available to the UE for the UE. The high power indicates that a larger 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, under the second secondary carrier technology, when the UE switches, the switch is made to The new UE 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 and estimates the signal to interference ratio (SIR: Signal to Interference Ratio) of the DPCCH. According to ^? The comparison result with the target signal interference ratio ^SIRt results in a power control command word, which is sent to the UE for reception by the downlink, and the UE receives the power control command word and adjusts the transmission power of the UE by using 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, if the power step is too low, the transmission power of the UE may be adjusted too slowly, and the transmission power of the UE is 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.

In order to perform more accurate adjustment on the transmit power of the UE, in the technical solution proposed by the embodiment of the present invention, the processor first adjusts the transmit power of the dedicated physical control channel DPCCH of the user equipment UE from the initial power to the first power step. The first transmit power, and then the DPCCH transmit power is adjusted from the first transmit power to the second transmit power by a second power step different from the first power step, and the transmitter transmits the first transmit power or the second transmit power The power is transmitted to the network side device. Compared with the prior art, the DPCCH transmission power is adjusted by only one power step. The present invention can send different power steps to the DPCCH for different adjustment stages. The power is adjusted to further improve the transmit 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 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, configured to pass the first transmit power and/or the second transmit power to The network side device sends data, that is, the data may be sent to the network side device by using at least one of the first sending power and the second sending power.

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 there is no Before receiving the AG sent by the network side device, it 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:

Pini = P _re f - power— margin [ 1 ] where P _mi represents the initial power;

P _ref represents the reference power;

Power—maral 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, in turn, can determine the initial power as soon as possible after switching or no data transmission for a period of time, 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 initial power to the network side device.

DPCCH.

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 ^SIRt , 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 ⁵ ^, the network side device determines to use a larger first power step; and if the SIR of the DPCCH differs from the ⁵ ^, the network side device determines that the network side device is smaller. The first power step size, etc., can ensure that the SIR of the DPCCH converges to ^ as soon as possible. If the SIR is higher than ^, a power control command word for reducing power is generated. If the SIR is lower, a power control command word for increasing 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, where n is a preset value.

Optionally, the processor 10 is further configured to: quantize the first power step to obtain the quantized first power step.

Optionally, the n is specifically: the number of delay slots for the UE to use the service grant SG to perform the enhanced dedicated channel dedicated physical data channel E-DPDCH data transmission, or the number of slots of the DPCCH prefix when the DPCCH is discontinuously transmitted. Or the sum of the number of time slots of the DPCCH prefix and the number of fixed time slots when the DPCCH is discontinuously transmitted.

Usually, a 2ms transmission time interval (TTI: Transmission Time Interval) If the delay of the E-DPDCH data transmission includes 5 TTIs and the number of delay slots is 15, then the first power step size can be determined as: 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 And decreasing the indication of the power, obtaining the first transmission power by subtracting the first power step from the initial power; and if the power lifting instruction is the indication of increasing the power, increasing the first power step by the initial power to obtain the first transmission 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, thereby generating a power control command word for the lifting power, wherein if

If the SIR is higher than ⁵ , a power control command word that reduces power is generated. If the SIR is lower than ⁵ , a power control command word that increases 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. Of course, other values may be used, which are not limited in the embodiment of the present invention.

As shown in Fig. 2a and Fig. 2b, for the sake of simplicity, 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. Less than the first power step represented 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. The network side device detects the SIR of the DPCCH, determines that it is smaller than the ^SIRt , and the SIR and the ^^ have a large difference, so the power is increased. a power control command word, which includes stepl, 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 to p+ste1;

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 ⁵ , and the SIR and the difference are larger, for example, the initial power setting of the UE side is too low. Or if the channel fading is just large, the SIR and the phase difference are large. The SIR is, for example, -12dB, ⁷ ^g, for example, 8dB. Therefore, the power control command word for increasing power is sent, including the stepl, the processor of the UE. 10 after receiving the power control command word through the receiver, 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, and determines that the ratio is small, so the power step is adjusted from step 1 to ^S s ^I t ^R ep ^t small. , and SIR and

2, further sending a power control command word that increases the power ^S rate ^IR ^ phase difference amplitude, where step 2 is included, after the processor 10 of the UE receives the power control command word through the receiver, Adjusting the DPCCH transmission power from the initial power p to p + 2 X ste l + step 2;

Then, the transmitter 11 of the UE transmits the DPCCH to the network side device through p+ 2 X step1+step2, and the network side device detects the SIR of the DPCCH, determines that it is smaller than ^SIRt , and SIR and

For example: If p+ 2 X ^SIR ^ is small, the transmission power of ste l+ step2 is just right, or the channel fading is just small, just making the SIR fluctuate around SIRtarget, it will make SIR just slightly smaller.

^SIRt , SIR is, for example, 7 dB, for example, 8 dB, so the power control command word of increasing power is continuously transmitted, including step 2, and the processor 10 of the UE transmits the power of the DPCCH from the initial power after receiving the power control command word through the receiver. p is adjusted 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 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 larger than ⁵ , and the SIR and the difference are larger, so the transmission is reduced. 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 to P-ste l;

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 ⁵ , and the SIR differs greatly from the ⁷ ^, for example, the initial power setting on the UE side is too large. The SIR determined by the network side device is larger than the difference of ⁵ , and the SIR is, for example, 15 dB, for example, 2 dB, so that the power control command word of the reduced power is sent, where the step 1 is included, and the processor 10 of the UE receives the work through the receiver. After controlling the command word, the DPCCH transmission power is adjusted 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 p-2 step1, and the network side device detects the SIR of the DPCCH, determines that it is larger than ^SIRt , and SIR and

Therefore, the power step is adjusted from step 1 to step 2, and then the power control command word with a smaller difference in the power ^S rate ^IR ^ is transmitted. Step 2, the processor 10 of the UE receives the power control command word through the receiver, and adjusts the DPCCH transmission power from the initial power p to P-2X ste l-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, determines that it is larger than ^SIRt , and SIR and

The transmission power of 816 1^6 2 is just right, and the ^SIR or ^ phase difference is small. For example: the transmission power - 2 channel fading is not large, in this case, the SIR may be slightly larger than ⁵ ^ a ^ , SIR is for example: 3dB, ^{SIRt is,} for example: 2dB, so continue to 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 step 1-2 χ step2, according to J3⁄4 analogy.

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 transmitter 31 is connected to the processor 30, and configured to send the power control command word including the power up/down command to the user equipment UE, so that the UE sends the dedicated physical control channel DPCCH of the UE according to the power lifting instruction and the first power step. 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.

Optionally, the processor 30 is further configured to determine a power headroom used by the UE;

The transmitter is further configured to: send the power headroom to the UE, so that the UE determines the initial power according to the obtained reference power and the power headroom. In a third aspect, based on the description of the first aspect, 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 sent by the network side device and a total control channel power margin C/P available to the UE;

The processor 41 is coupled to the receiver 40 for determining the SG based on at least ^ rgw and c/P.

As shown in FIG. 5, a timing relationship diagram for transmitting and applying a dedicated physical data channel (E-AGCH: E-DCH Dedicated Physical Data Channel) for enhancing an E-DCH (Enhanced Dedicated Channel) is switched to by UE3. After UE1, the first absolute grant (AG: Absolute grant) sent by the network side device is delayed (after 5 is shown in Figure 5), that is, the second #0 TTI can take effect. AG usually refers to Is 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 because in the above solution, the SG used for initial transmission of the E-DCH dedicated physical data channel channel can be determined on the UE side, so that the UE's transmission does not exceed the network load target 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. The statistical block error rate is compared with the block error rate target value. If it is greater than the target value, the SIR _tar g _{et is} lowered to a smaller value. If it is smaller than the target value, the SIR _{ta et is} adjusted to a larger value. Value, and C/P is set directly by the network.

Optionally, the network side device may perform uplink and _C /p to the UE through high layer signaling. Optionally, the processor 41 can represent the correspondence between SG and ^SIRt 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 ) In the specific implementation process, the processor 11 determines the SG according to at least ⁷ ^g and C/P, and can be used in various cases. The following two examples are introduced, of course, In the specific implementation process, it is not limited to the following two cases.

The first way:

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

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.
