Description

Method and terminal for determining service authorization value

The present invention relates to the field of communications, and in particular, to a method and a terminal for determining a service authorization value. Background technique

MIMO (Multiple Input Multiple Output) technology is used to increase the peak rate of users in systems such as LTE (Long Term Evolution) and UMTS (Universal Mobile Telecommunications System). technology.

In the UMTS system, the network schedules the UE (User Equipment) based on the interference level of the air interface, and ensures the quality of service of the network through the reasonable allocation and use of air interface resources. Specifically, the base station (NodeB) measures the current real-time load of the UE, compares the current real-time load with a preset target load that characterizes the interference level, determines the current maximum transmit power of the UE according to the comparison result, and passes the SG (Service Grant). The service authorization information is sent to the UE to implement control of the UE transmit power. Similarly, in an uplink MIMOOJplink MIMO (UL MIMO) scenario, the base station determines the mainstream SG value of the UE by considering the power load of the mainstream data and the auxiliary stream data, and sends the SG value to the UE, and the secondary stream SG value can be determined by the UE. The mainstream SG value and the primary-auxiliary stream-to-noise ratio are calculated to achieve cell load control and cell throughput maximization.

In the MIMO system, the short frame interval is used, that is, the TTI (Transmission Time Interval) of the 2ms E-DCH (Enhanced Dedicated Channel), and the TMS of the 2ms E-DCH is the mainstream service grant value. It will take a while for the receiver to take effect. Summary of the invention

It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to Figure 1, there is shown a flow diagram of a first embodiment of a method of determining a service grant value of the present invention.

The executor of the embodiment of FIG. 1 may be a terminal, such as a UE, and the UE may be a normal mobile phone or a smart phone. The method flow of Figure 1 includes:

Step S11: Acquire a first service authorization value from the base station.

The base station may be a base station supporting MIMO technology, and the MIMO technology is generally applied to systems such as LTE or UMTS. Therefore, the base station herein mainly refers to a base station in a system such as LTE or UMTS. The execution subject terminal of step S11 also refers to a terminal supporting MIMO technology.

Step S12: Calculate the second service authorization value at the current time based on the first service authorization value at the transmission time of the uplink enhanced dedicated channel corresponding to the first service authorization value.

In this embodiment, the new second service is recalculated based on the obtained first service authorization value on the transmission time of the uplink enhanced dedicated channel corresponding to the first service authorization value, that is, the effective time of the first service authorization value. The authorization value, and thus the recalculated second service authorization value, can be better matched to the current channel condition than the prior art directly using the first service authorization value. In the implementation manner of step S11 in FIG. 1, the UE may also acquire first rank information from the base station when acquiring the first service authorization value. Alternatively, the UE may also acquire first information and first rank information from the base station when acquiring the first service authorization value. The first information will be introduced later. The process of obtaining the first service authorization value and the first rank information, or acquiring the first service authorization value, the first information, and the first rank information will be described below with reference to FIG.

As shown in Figure 2, in one embodiment:

Step S21: Receive an absolute authorization command from the base station in the jth subframe of the E-AGCH frame with the SFN (System Frame Number) i, where i and j are positive integers.

The absolute authorization command may include: a mainstream service authorization value, or a service authorization reference value of the mainstream and auxiliary streams. The mainstream service authorization value can be an index of "0 ~ 37", and the service authorization reference value of the mainstream and auxiliary stream can be used to calculate the mainstream auxiliary stream service authorization value, and the generally calculated mainstream service authorization value. It can also be the index of "0 - 37"

Generally, when the first service authorization value is sent to the UE, the base station also transmits the first information and the first rank information to the UE. When the absolute authorization command includes: the mainstream service authorization value, the first information may be used to calculate the auxiliary Stream service authorization value. However, there may be no first information at this time. For example, when the first rank information is 1, this is because rank (rank information) =1, indicating that the base station notifies the UE that the channel is only suitable for single stream transmission at this time, and is not suitable for dual stream ( ; mainstream, auxiliary stream) transmission.

When the absolute authorization command includes: the service authorization reference value of the mainstream and the auxiliary stream, the first information is used to calculate the mainstream service authorization value and the auxiliary stream service authorization value. Of course, if rank=l at this time, the first information is only used to calculate the mainstream service authorization value.

It should be added that although in most cases, the value of rank is notified to the UE by the base station, it is also possible for the UE to change the value of rank by itself. For example, when the UE is in a buffer restricted or power limited situation, the UE may adjust the actual transmit data amount or reduce the transmit power by itself; if the UE adjusts the transmit data amount or the transmit power by itself, the UE may use a single stream to send data ratio. The case where the dual-stream transmission data has better data transmission performance; when the UE finds this situation, the UE can convert the data from the dual stream to the single stream, and the UE can set the value of the rank to 1.

It may be further added that, in practice, the first information and the rank information are updated every time, and

The UE may receive the first information and the rank information through the S-E-AGCH (Secondary/Secondary-E-DCH-Absolute Grant Channel). Step S22: Obtain the first service authorization value in the absolute authorization command in step S21, and obtain the first information received at the time when the jth subframe is located and the first rank information received at the time of the first rank information or the jth subframe.

Wherein, when the absolute authorization command is the mainstream service authorization value, generally, when the rank=2 of the jth subframe, the first information of the jth subframe exists, and at this time, the time at which the jth subframe is received is simultaneously acquired. The first information and the first rank information; and when the rank=l of the jth subframe, the first information of the jth subframe does not exist, and only the first rank information received at the time of the jth subframe needs to be acquired. . Of course, if the service authorization reference value is the primary and secondary stream in the absolute authorization command, the first information of the j-th subframe and the first rank information should be acquired at the same time; however, it should be noted that if the rank j of the j-th subframe is , the first information may only include the mainstream information, that is, the mainstream information reference ratio or the mainstream information reference difference. As shown in Figure 3, in one embodiment:

Step S31: Receive a relative grant command from the base station on the jth subframe of the serving cell E-RGCH frame with the SFN being i, where i and j are positive integers.

The relative authorization command includes a relative authorization value, which may be one of "UP", "DOWM", and "HOLD". The UE may calculate a service grant value based on the relative grant value and the reference value, the selection of the reference value being illustrated in step S32. Specifically, "DOWM" generally means minus one, and "UP" can be pre-configured. Generally, it is configured as "+1", "+2" or "+3", and "HOLD" means unchanged. For example: If the relative authorization value in the relative authorization command received is "DOWM", then the difference of the reference value minus one is the service authorization value.

Step S32: Calculate the first service authorization value according to the relative authorization value in the relative authorization command and the service authorization value of the subframe in which the reference_ETPR (ie, the first reference data pilot power ratio) is located.

In this embodiment, the service authorization value of the subframe in which the reference-ETPR is located is used as a reference value, and the first service authorization value is calculated in combination with the relative authorization value. For example: If the relative authorization value is "HOLD", the calculated first service authorization value is the same as the service authorization value of the reference-ETPR subframe, if the relative authorization value is "UP" and "UP" is configured as " +1 " , the calculated first service authorization value is reference - the service authorization value of the subframe in which the ETPR is located is incremented by one.

Reference- ETPR refers to the power ratio of the reference E-DPDCH (E-DCH Dedicated Physical Control Channel) and the DPCCH (Dedicated Physical Control Channel) of the serving cell relative authorization command. Sets the power ratio of E-DPDCH to DPCCH for E-TFC selection for the same process in the previous one. It should be noted that reference-ETPR is a concept familiar to those skilled in the art.

It should be noted that the first service authorization value calculated in step S32 may be a mainstream service authorization value or a service authorization reference value of the mainstream and auxiliary streams.

Step S33: Obtain the first service authorization value calculated in step S32, and obtain the first information and the first rank information received at the time corresponding to the subframe where the reference-ETPR is located, or obtain the first service authorization value calculated in step S32, And obtaining the first rank information received at the time corresponding to the subframe where the ETPR is located. As shown in Figure 4, in one embodiment:

Step S41, receiving the base from the j-th subframe of the non-serving cell E-RGCH frame with the SFN being i The relative authorization command of the station, where i and j are positive integers.

The meaning of the relative authorization command here is the same as that of the embodiment of Fig. 3, except that the UE receives the relative authorization command through the non-serving cell E-RGCH channel.

Step S42: Calculate the first service authorization value according to the relative authorization value in the relative authorization command and the maximum value of all service authorization values in the cycle period in which the reference_ETPR2 (ie, the second reference data pilot power ratio) is located.

Here, the difference from step S32 in FIG. 3 is: when calculating the first service authorization value, the maximum value of all service authorization values in the loop period in which reference-ETPR2 is located is used as a reference value, and the relative authorization value is combined on the basis of this. , calculate the first service authorization value.

Where reference_ETPR2 is: the power ratio of the reference E-DPDCH to the DPCCH for the non-serving cell relative grant command, which is set to E-TFC for the same process in the previous reference-ETPR. The power ratio of DPDCH to DPCCH.

Step S43: Obtain the first service authorization value calculated in step S42, and obtain the first information and the first rank information received at the time corresponding to the subframe where the maximum value is located, or obtain the first rank information received at the time corresponding to the subframe where the maximum value is located. FIG. 2 to FIG. 4 are a detailed description of step S11 in FIG. 1. When the first service grant value is the mainstream service grant value, the uplink enhanced dedicated channel corresponding to the first service grant value of step S12 in FIG. 1 is used. The transmission time is explained. specifically:

That is, the service grant value received on the jth subframe of the i th E - AGCH frame, and the corresponding uplink E-DCH transmission time is the t th subframe of the i + s E - DPDCH frame.

^F-DPCH, n °

2) For the E-RGCH (E-DCH Relative Grant Channel) channel of the serving cell:

The E-DCH control information (ie, the mainstream service grant value) received by the UE on the jth subframe of the E-RGCH frame whose SFN is i is the j-th subframe corresponding to the E-DPDCH frame whose SFN is i+1. That is, the mainstream service grant value received in the jth subframe of the i E-RGCH frame, the corresponding uplink E-DCH transmission time is valid for the jth subframe of the i+1th E-DPDCH frame.

' DPCH . The frame offset of the nth DPCH, when the downlink F-DPCH is configured, in the formula

3) For the E-RGCH channel of the non-serving cell:

The E-DCH control information (ie, the mainstream service grant value) first received by the UE on any subframe of the E-RGCH frame with the SFN being i is the t-th of the E-DPDCH frame corresponding to the SFN being i+1+s. Subframes. That is, the primary service grant value received first in any subframe of the i-th E-RGCH frame, and the corresponding uplink E-DCH transmission time is the i-+1 + s E-DP DCH frame. The tth subframe.

Where ^ is the nth DPCH frame offset. When the downlink F-DPCH is configured, the DPCH frame offset in the formula is _Pffl>i = F-DPCH frame offset ^ _npr ^.

Referring to FIG. 5, the service authorization value is the mainstream service authorization value, and the first information and the second information are the signal to interference and noise ratios of the mainstream and the auxiliary stream, and are represented by SR (SINR Ratio, ie, Signal-to-noise ratio Ratio). An example of an embodiment of the present invention is described:

The following describes the terminal that executes the above method embodiment.

Please refer to FIG. 6, which is a schematic structural diagram of an embodiment of a terminal for determining a service grant value of the present invention. The terminal includes:

The obtaining unit 11 is configured to obtain a first service authorization value from the base station.

The base station may be a base station supporting MIMO technology, and the MIMO technology is generally applied to systems such as LTE or UMTS. Therefore, the base station herein mainly refers to a base station in a system such as LTE or UMTS. A terminal is also a terminal that supports MIMO technology.

The calculating unit 12 is configured to calculate, according to the first service authorization value, the second service authorization value at the current moment, at the transmission moment of the uplink enhanced dedicated channel corresponding to the first service authorization value.

In this embodiment, the new second service is recalculated based on the obtained first service authorization value on the transmission time of the uplink enhanced dedicated channel corresponding to the first service authorization value, that is, the effective time of the first service authorization value. The authorization value, and thus the recalculated second service authorization value, can be better matched to the current channel condition than the prior art directly using the first service authorization value. In the implementation manner of the obtaining unit 11 in FIG. 6, when acquiring the first service authorization value, the first rank information from the base station may also be acquired. Alternatively, when acquiring the first service authorization value, the first information and the first rank information from the base station may also be acquired.

The first receiving subunit 71 is configured to receive an absolute authorization command from the base station on the jth subframe of the E-AGCH frame with the SFN (System Frame Number) i, where i and j are positive integers.

The absolute authorization command may include: a mainstream service authorization value, or a service authorization reference value of the mainstream and auxiliary streams. The mainstream service authorization value can be an index of "0 ~ 37". The service authorization reference value of the mainstream and auxiliary streams can be used to calculate the mainstream auxiliary stream service authorization value. The generally calculated mainstream service authorization value can also be "0 - 37". Index

Generally, when the base station sends the first service authorization value to the UE, the base station also transmits the first information and the first rank information to the UE. When the absolute authorization command includes: the mainstream service authorization value, the first information may be used to calculate the auxiliary stream. Service authorization value. However, there may be no first information at this time. For example, when the first rank information is 1, this is because rank (rank information) =1, indicating that the base station notifies the UE that the channel is only suitable for single stream transmission at this time, and is not suitable for dual stream ( ; mainstream, auxiliary stream) transmission.

It may be further added that, in practice, the first information and the rank information are updated once every time, and the UE can receive the first information and the rank information through the S-E-AGCH channel.

The first obtaining sub-unit 72 is configured to obtain a first service authorization value in the absolute authorization command, and obtain the first information received at the time when the j-th subframe is located, and the first information received at the time of the first rank information or the j-th subframe Rank information. Wherein, when the absolute authorization command is the mainstream service authorization value, generally, when the rank=2 of the jth subframe, the first information of the jth subframe exists, and at this time, the time at which the jth subframe is received is simultaneously acquired. The first information and the first rank information; and when the rank=l of the jth subframe, the first information of the jth subframe does not exist, and only the first rank information received at the time of the jth subframe needs to be acquired. . Of course, if the service authorization reference value is the primary and secondary stream in the absolute authorization command, the first information and the first rank information of the j-th subframe should be acquired at the same time; but it needs to be explained that if the rank of the j-th subframe is l , the first information may only include the mainstream information, that is, the mainstream information reference ratio or the mainstream information reference difference.

The UE may calculate a service grant value based on the relative grant value and the reference value, the selection of the reference value being illustrated in step S32. Specifically, "DOWM" generally means minus one, and UP" can be pre-configured, generally configured as "+1", "+2" or "+3", and "HOLD" means unchanged. For example: If received The relative authorization value in the relative authorization command is "DOWM", then the difference of the reference value minus one is the service authorization value.

The first calculating sub-unit 82 is configured to calculate the first service authorization value according to the relative authorization value in the relative authorization command and the service authorization value of the subframe in which the reference_ETPR (ie, the first reference data pilot power ratio) is located.

If rank-1=2, rank-2=1, then according to the formula:

If rank-1=1, rank-2=1, then according to the formula:

SG old =SG new =Mainstream service authorization value at the current moment. Calculate the mainstream service at the current moment. Service authorization value;

22. The terminal according to any one of claims 15 to 18, characterized in that, when the first service authorization value is the service authorization reference value of the main stream and the secondary stream, the first information and the second information include: on the base station side, When the reference difference between the mainstream information and the auxiliary stream information is different, the calculation unit is used to

If rank-1=2, rank-2=2, then according to the formula:

(SG— old - SR_old_l ) + ( SG_old - SR— old— 2 ) = ( SG— new - SR_ new _1 ) + ( SG_ new - SR_ new _2 ), and ( SG_new - SR_ new 1 ) = the mainstream at the current moment Service authorization value, calculate the mainstream service authorization value at the current moment, and

If rank-1=2, rank-2=1, then according to the formula:

If rank-1=1, rank-2=2, then according to the formula:

If rank-1=1, rank-2=1, then according to the formula:

Among them, rank-1 is the first rank information, rank-2 is the second rank information, SR-old-1 is the recorded mainstream information reference difference, SR-old-2 is the recorded auxiliary stream information reference difference, SG-old is Main stream and auxiliary stream of record The service authorization reference value of value.
