Description

UE, Network Side Equipment, Power Adjustment Method, and SG Determination Method This application is required to be submitted to the Chinese Patent Office on March 17, 2014. 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 SG Determination Method, adopted in its entirety, is hereby incorporated in this application. technical field

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

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

The advantage of the second auxiliary carrier technology is that only one or a small number of UEs send data at the same time, which greatly reduces the multiple access interference between UEs. In addition, since a UE can occupy relatively high load resources within a transmission time interval (TTI: Transmission Time Interval), the UE can perform high-speed data transmission.

The transmission of the uplink UE in the wideband code division multiple access mobile communication system (WCDMA: Wideband Code Division Multiple Access) is completed through scheduling, and the base station measures the signal-to-noise ratio based on the dedicated physical control signal (DPCCH: Dedicated Physical control Channel) of the UE , sending a serving grant (SG: Serving Grant) representing the maximum power available to the UE to the UE, where a large power indicates that a larger block length can be scheduled.

In the traditional way, before the UE starts sending uplink enhanced dedicated channel (E-DCH Enhanced: Dedicated Channel) data, it will send a DPCCH power control prefix for a period of time, which is used for channel quality synchronization. However, under the second secondary carrier technology, when the UE is handed over, the new UE to be handed over may not have a DPCCH power control prefix, so the base station cannot determine the initial power used by the UE to start sending until the base station receives the uplink transmission of the UE. DPCCH and estimate the signal-to-interference ratio (SIR: Signal to Interference Ratio) of DPCCH, according to ^? The power control command word is obtained from the comparison result with the target signal-to-interference ratio ^SIRt , which is sent downlink to the UE for reception. The UE receives the power control command word and adjusts the transmit power of the UE through the power step included in the power command word.

There are two kinds of power steps specified in the current agreement, one is to adjust ldB per time slot, and the other is to adjust 2dB per time slot. If the power step size determined by the method in the prior art is too low, it may cause the UE's transmit power to be adjusted too slowly, which in turn may cause the UE's transmit power to be too low, and the available load cannot be fully utilized; and If the power step size 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 transmit power of the UE is not accurate enough.

In order to adjust the transmit power of the UE more accurately, in the technical solution proposed here in 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 transmit power, and then adjust the DPCCH transmit power from the first transmit power to the second transmit power through the second power step different from the first power step, and the transmitter uses the first transmit power or the second transmit power The power is used to send data to the network side device. Compared with the method of adjusting the DPCCH transmission power only through one power step in the prior art, the present invention can use different power steps for different adjustment stages to transmit the DPCCH. The power is adjusted, so that the DPCCH transmission power is more accurate, and it can ensure 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 realization principles, specific implementation modes and corresponding beneficial effects that can be achieved of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

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

Using the first power step to adjust the transmission power of the dedicated physical control channel DPCCH of the user equipment UE from the initial power to the first transmission power; and

determining a second power step different from the first power step,

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

The transmitter 11 is connected to the processor, and is used to transmit the first transmission power and/or the second transmission power to The network-side device sends data, that is, it may send data to the network-side device by using at least one of the first transmit power and the second transmit power.

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

The processor 10 is also configured to: acquire reference power, and determine initial power according to the reference power and the power headroom.

Since the base station cannot determine the initial power of the DPCCH used by the UE to start sending when the UE is handed over or when the UE has not sent data for a long time, it is necessary to determine an appropriate initial power of the DPCCH for the UE in the initial sending stage. Data can also be sent before the AG sent by the network side device is received, thereby improving resource utilization.

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

However, the DPCCH in the present invention can be configured with a primary carrier and a secondary carrier, so that the solution can be applied to a 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, etc. , the two powers can be detected by the UE itself, and the embodiment of the present invention does not limit the method used to obtain the reference power.

When the current power of the main carrier is the current uplink power, since the frequency interval between the current uplink frequency of the main carrier and the auxiliary carrier is small, and usually the UE sends DPCCH through the auxiliary carrier, it can ensure 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: The initial power can be obtained by the following formula:

Pini = P _ref - power— margin [ 1 ] Among them, P _mi represents the initial power;

P _ref represents the parameter power;

power—margin indicates the power margin.

Through the above solution, it is ensured that after the UE is handed over, 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 can be determined as soon as possible after handover or no data transmission for a period of time, thereby achieving the technical effect of fully utilizing the available network load.

The processor 10 may determine the first power step size in a variety of ways, two of which are listed below for introduction, of course, in the specific implementation process, it is not limited to the following two situations.

In the first manner, 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 the first power step;

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

After the UE determines the initial power, the transmitter 11 sends the initial power to the network side device

DPCCH.

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

Signal to Interference Ratio ), and then compare it with the target signal-to-interference ratio ^SIRt , and then generate a power control command word for raising or lowering power, and send it to the UE for power adjustment. For example: if the difference between the SIR of the DPCCH and ⁵ ^ is large, the network side device determines to use a larger first power step size; and if the difference between the SIR of the DPCCH and ⁵ ^ is small, the network side device determines to use a smaller first power step size. The first power step size of , etc., can ensure that the SIR of the DPCCH converges to ^ as soon as possible. Wherein, if the SIR is higher than ^, a power control command word for reducing power is generated, and if the SIR is lower than, a power control command word for increasing power is generated.

In the second manner, the processor 10 is specifically configured to: determine the quotient obtained by dividing the absolute value of the power headroom sent by the network side device by n as the first power step size, and n is a preset value.

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

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

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

Optionally, the receiver may also receive a power control command word sent by the network side device including a power up and down command, and then determine the first transmission power through the first power step size and the power up and down command, for example: If the power up and down command is If the instruction to reduce power, the first transmit power is obtained by subtracting the first power step from the initial power; if the power increase instruction is an instruction to increase power, the first transmit power is obtained by increasing the initial power by the first power step.

Wherein, if the first power step size is sent to the UE by the network side device through the power control command word, the power control command word may include both the first power step size and the power up and down instruction; and if the first power step size is set by If determined by the UE side, the power control command word only includes the power up and down command.

Optionally, the UE may adjust the initial power through the first power step multiple times, so as to determine the first transmission power.

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

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

In the specific implementation process, the UE first transmits to the network side equipment through the first transmission power

DPCCH; after receiving the DPCCH, the network side equipment estimates the SIR of the DPCCH, and then compares it with the target signal-to-interference ratio, and then generates a power control command word for raising or lowering the power, where if

If the SIR is higher than ⁵ , a power control command word for reducing power is generated, and if the SIR is lower than ⁵ , a power control command word for increasing power is generated. Finally, the network side device sends the power control command word including the power up and down command and the second power step to the UE.

After the UE side receives the power control command word including the power control command word and the second power step size, the processor 10 also determines the second transmission power through the power control command word contained in the power control command word. For example: If the instruction is an instruction to increase power, the second transmission power is determined by adding the first transmission power to the second power step; Transmitting determines a second transmit power and so on. Similarly, the processor 10 may adjust the first transmission power through the second power step multiple times, and then determine the second transmission power. Moreover, since the adjustment of the DPCCH transmission power through the second power step is located after the adjustment of the DPCCH transmission power through the first power step, it usually belongs to fine-tuning information, so that the second power step is usually smaller than the first power step, For example: the first power step size is 2dB, and the second power step size is IdB, and of course other values may also be used, which are not limited in this embodiment of the present invention.

As shown in Figure 2a and Figure 2b, wherein for the sake of simplicity, in Figure 2a and Figure 2b, p represents the initial power, stepl represents the first power step size, step2 represents the second power step size, and step2 represents the second power step size Less than the first power step indicated by stepl.

Fig. 2a is a schematic diagram of power adjustment when both the power control command word of the first power step and the power control command word of the second power step include an instruction to increase power.

First determine the initial power p, 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, and determines that it is smaller than ^SIRt , and the difference between SIR and ^^ is large, so the increased power is sent The power control command word, which includes step1, after the processor 10 of the UE receives the power control command word through the receiver, 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 equipment through p+step1, and the network side equipment detects the SIR of the DPCCH, and determines that it is smaller than ⁵ , and the difference between the SIR and ^^ is large, for example: the initial power setting of the UE side is too low, Or when the channel fading happens to be large, it will lead to a large difference between the SIR and the phase, for example, the SIR is -12dB, and the SIR is, for example, 8dB; therefore, the power control command word for increasing the power is sent, which includes ^stepl , the processor of the UE 10 After receiving the power control command word through the receiver, adjust the DPCCH transmission power from the initial power p to p+ 2 X stepl;

Then the transmitter 11 of the UE sends the DPCCH to the network side equipment through p+ 2 X stepl, and the network side equipment detects the SIR of the DPCCH and determines that the ratio is small, so the power step is adjusted from stepl to ^S s ^I t ^R ep ^{t is} small , and SIR with

2. Further, send a power control command word that increases the power ^S rate ^IR ^ phase difference, 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 ste l+ step2;

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

For example: If the difference between p+ 2 X ^SIR ^ is small, the transmit power of ste l+ step2 is just right, or the channel fading is just small, which just makes the SIR fluctuate around the SIRtarget, and the SIR is just slightly smaller than

^SIRt , the SIR is for example 7dB, for example 8dB, so the power control command word with increased power is continued to be sent, which includes step2, after the processor 10 of the UE receives the power control command word through the receiver, the DPCCH transmission power is changed from the initial power p is adjusted to p+ 2 X step 1+2 step2; and so on.

Fig. 2b is a schematic diagram of power adjustment when both the power control command word of the first power step and the power control command word of the second power step include a power reduction instruction.

First determine the initial power p, 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 and determines that it is greater than ⁵ , and the difference between the SIR and ^ is large, so the transmission power is reduced The power control command word, which includes step1, after the processor 10 of the UE receives the power control command word through the receiver, 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 equipment through P-step1, and the network side equipment detects the SIR of the DPCCH, and determines that it is greater than ⁵ , and the difference between the SIR and ⁷ ^ is large, such as the initial power setting of the UE side is too large, The difference between the SIR determined by the network side equipment is larger than ⁵ , and the SIR is, for example, 15dB, for example, 2dB. Therefore, a power control command word with reduced power is sent, which includes stepl, and the processor 10 of the UE receives the power through the receiver. After the control command word, adjust 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 equipment through p-2 step1, and the network side equipment detects the SIR of the DPCCH, and determines that it is larger than the ^SIRt , and the SIR and

, so the power step is adjusted from step1 to step2, and then a power control command word with a reduced power ^{rate IR} and a small difference is sent, which includes step2, after the processor 10 of the UE receives the power control command word through the receiver , adjust the DPCCH transmission power from the initial power p to P- 2 X ste l-step2;

Then the transmitter 11 of the UE sends the DPCCH to the network side device through P-2X step1-step2, and the network side device detects the SIR of the DPCCH and determines that it is greater than the ^SIRt , and the SIR and

The transmission power of 816 1^6 2 is just right, the ^SIR or ^ phase difference is small, for example: the transmission power - 2 and the channel fading is not large, in this case, the SIR may be slightly greater than ⁵ ^a^, and the SIR is for example: 3dB, ^SIRt is, for example: 2dB, so continue to send the power control command word with reduced power, which includes step2, after the processor 10 of the UE receives the power control command word through the receiver, adjust the DPCCH transmission power from the initial power p to P- 2 X step 1-2 x step 2, and so on.

In the second aspect, based on the description of the embodiment of the first aspect, the embodiment of the present invention provides a network side device, please refer to FIG. 3, which specifically includes:

Processor 30, configured to determine a power control command word including a power up and down command;

The transmitter 31, connected to the processor 30, is configured to send the power control command word including the power up and 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 up and down command and the first power step The power is adjusted from the initial power to the first transmission power;

The processor 30 is further configured to: determine the power control command word including the second power step;

The transmitter 31 is further configured to: send the power control command word including the second power step to the user equipment UE, so that the UE adjusts the first transmission power to the second transmission power through the second power step, where the first The first power step and the second power step are different power steps.

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

The transmitter is also used 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 transmission power from the initial power to the first transmission power through the first power step.

Optionally, the processor 30 is further configured to determine the 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 the third aspect, based on the description of the embodiment of the first aspect, the embodiment of the present invention provides a user equipment UE, please refer to FIG. 4, including:

The receiver 40 is configured to receive the target signal-to-interference ratio sent by the network side device and the total control channel power headroom C/P available to the UE;

A processor 41, connected to the receiver 40, for determining SG based on at least ^rgw and c/P.

As shown in FIG. 5, it is a time sequence relationship diagram of transmission and application of a dedicated physical data channel (E-AGCH: E-DCH Dedicated Physical Data Channel) of an enhanced dedicated channel (E-DCH: Enhanced Dedicated Channel), when switching from UE3 to After UE1, the first absolute grant (AG: Absolute grant) sent by the network side device will be delayed for a period of time (after 5 ΤΉ in Figure 5), that is, the second #0 TTI will take effect, and AG usually refers to is the SG carried on the E-AGCH channel, and SG represents the maximum power available to the UE.

Therefore, in the initial sending stage, it is necessary to determine the appropriate initial power of the E-DPDCH for the UE, so as to ensure that data can be sent before the SG sent by the network side device is received, thereby improving resource utilization.

And because in the above scheme, the SG used for the initial transmission of the E-DCH dedicated physical data channel (DCH) can be determined on the UE side, it can be ensured that the transmission of the UE will not exceed the load target of the network, and the processing load of the network side equipment is reduced .

In the specific implementation process, the SIR _target is determined by the RNC statistics of the demodulation block error rate of E-DPDCH data according to a certain outer loop power control algorithm, for example, the block error rate of a previous period of time is counted. Comparing the statistical block error rate with the block error rate target value, if it is greater than the target value, then adjust the SIR _tar get to a smaller value, if it is less than the target value, then adjust the SIR _{ta et to} a larger value value, and C/P is directly set by the network.

Optionally, the network side device may overlay and _C /p to the UE through high layer signaling. Optionally, the processor 41 may express the corresponding relationship between SG, ^SIRt and c/P through 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 can determine SG according to at least ⁷ ^g and C/P in many situations, and two of them are listed below for introduction. Of course, in the specific implementation process, it is not limited to the following Two situations.

The first way:

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

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

In this case, the processor 41 is specifically configured to: at least determine SG according to , C/P, and Load, that is, the following formula can be used to express the correspondence between SG and ^SIR t, c/P, and Load:

SG=function( ^SIRt , c/P, Load ) [3] When the processor 41 determines SG according to S ⁷ ^g , C/P and Load, it can be divided into at least two situations, which will be introduced respectively below.

①The processor 41 only determines SG through , C/P and Load, for example, it can further calculate and determine SG through the following formula:

SIR t, target *

1 + SG + - ≤ Load •[4]

256 [P.

In the above formula, the SG determined when taking the equal sign is a better SG, which can not only ensure that the network load can be fully utilized, but also can ensure that the network load will not exceed the available network load of the UE.

②The receiver 40 is also used to: before at least determining the SG according to, Load, and C/P, receive the power margin power-margin sent by the network side device; in this case, the processor 41 then according to, Load, C/P /P and power-margin determine SG, that is, the corresponding relationship between SG and ^SIRt , C/P, Load and power-margin can be expressed by the following formula:

SG=function ( , C/P, Load, power-margin ) [5] As the first embodiment of the formula [5], the processor 41 can further calculate and determine SG through the following formula:

+ power _ m arg in 1 + SG +

, 256

The above calculation formula is usually applied to a UE that transmits data through a single antenna, so as to ensure that the transmission of the UE will not exceed the load target of the network in the single-antenna system, and reduce the processing burden of the network side equipment.

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

.SIRt arg βΐ ., ,, c^, C, _f SIRt arg et \ ^ τ

( ~ ~ + power _ m arg in) + ) + ( ~ ~ + power _ m arg w) ≤ Load [7] The above calculation formula is usually applied to UEs that transmit data through multiple antennas. Compared with the formula

According to [6], the power overhead of the pilot channel is increased, because one of the differences between the multi-antenna and the single antenna is that the multi-antenna needs to send one more pilot channel.

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

^^L l ₊ SG + ^) +^^≤Load [8]

256 P 256

The second way:

The receiver 40 is further configured to: before determining the SG according to the ^{SIR (} and the CP, receive the available network load factor η of the UE sent by the network side device; in this case, the processor 41 is specifically configured to: at least based on ⁵ ^ ^a , C/P and η determination

SG, that is, the corresponding relationship between SG and ^SIRt , C/P and η can be characterized by the following formula:

SG=function ( ^SIR ^ , C/P, η ) [9] When the processor 41 determines SG according to , C/P, and η, it can be divided into at least two situations, which will be introduced separately below.

① The processor 41 only determines SG based on ⁵ ^ , C/P, η, for example, through the following formula

SG:

②The receiver 40 is also used for:

Before determining the SG based on , C/P and η, receiving the power margin power_margin sent by the network side device;

The processor 41 is specifically used for:

Determine SG based on , c/P, η and power-margin, that is, the corresponding relationship between SG and ^{S! Rt} t, C/P, η and power-margin can be characterized by the following formula:

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

1

η •[12]

The above calculation formulas are generally applied to UEs that transmit data through a single antenna.

As a second embodiment of the formula [11], the processor 41 can further determine SG by the following formula: ( ~ ~ + power m arg in) * (1 + 5G +— ) + ( ~ ~ + power m arg in) [13] The above calculation formula is usually applied to UEs that perform data transmission through multiple antennas.
