Description

Uplink data transmission method and device

Technical Field

The present invention relates to the field of communications, and in particular, to an uplink data transmission method and apparatus.

Background

Multiple Input Multiple Output (MIMO) technology is widely used in Long Term Evolution (LTE) and Universal Mobile Telecommunications System (UMTS). It is characterized by that after the data is undergone the process of multiple cutting, it can be synchronously transferred by means of multiple antennas. The MIMO technology can not only increase the data transmission speed of the wireless network frequency spectrum, but also increase the signal receiving distance without additionally occupying frequency spectrum resources.

In the UMTS system, a base station is provided with a target load ROT target used for representing the interference level, and measures the current real-time load, compares the current real-time load with the target load, determines the maximum power which can be transmitted by the UE currently, and transmits the maximum power to the UE in the form of Service Grant (SG) so as to control the transmitting power of the UE. The UE can determine the length of the currently transmitted data block according to the obtained SG, so that the load of the base station is ensured not to exceed the target load, and the interference level of the UE to the network is controlled.

In UL MIMO scenario, the base station needs to determine SG of the user primary/secondary stream, and also determines rank value of the user channel, where the rank value is used to indicate that the UE performs data transmission in a single stream mode of the primary stream or a dual stream mode of the primary/secondary stream. After the SG of the main stream is determined, the SG of the sub stream is calculated from the sub stream-related information and the SG of the main stream. The UE needs to determine the SG of the main stream, the related information t of the auxiliary stream, and rank information, and then uplink transmission can be performed.

However, in the prior art, the several information validation time criteria are not specified. If the original rank value indicates single-stream transmission and the new rank value indicates double-stream transmission, but the new rank value does not take effect, and the SG and the auxiliary stream related information take effect first, the UE still only uses the indicated main stream block length to perform uplink single-stream transmission, so that the uplink transmission quality is reduced; similarly, when the rank information is valid and the SG and the auxiliary stream related information are valid later, if the rank information indicates dual stream transmission, the UE cannot obtain the latest auxiliary stream grant because the auxiliary stream related information is not valid at this time, so the UE can only continue uplink auxiliary stream transmission using the original auxiliary stream block length, which also reduces the uplink transmission efficiency.

Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

When the UE has limited buffer, small buffer data amount or limited UE power, and cannot send data according to the authorized data block length given by the maximum SG, the UE needs to adjust the actual transmission data amount or adjust the transmission power downward. In this case, it may happen that the UE transmits data using the dual stream in a performance inferior to that of transmitting data using the single stream. At this time, the UE needs to judge the transmitted rank number again, and if it is judged that a larger throughput can be obtained by using single stream transmission, the UE will automatically fall back to single stream for data transmission, and at this time, the UE needs to determine the SG information for transmitting data by using single stream. That is, the UE may autonomously select rank information to transmit uplink data.

In the prior art, the data amount is large in the MIMO system, so that only the transmission time interval TTI of 2ms E-DCH exists, and the timing at which the SG takes effect from the reception is set as follows.

First, when sending the SG in the E-AGCH channel, the UE receives the SG firstly on the jth subframe of the E-AGCH control channel in the i-th SFN, and then on the t-th subframe of the E-DPDCH data channel frame in the i + s SFN. The specific calculation method comprises the following steps:

wherein, tau_DPCH，nRepresenting the amount of control channel frames that are cheap. Let i equal 0, j equal 1, τ_DPCH，nIf the value is 0, according to rounding-up, s is 1, and t is 0, it proves that the SG information transmitted on the 1 st subframe of the 0 system frame is valid in the 0 th subframe of the E-DPDCH data channel frame in the 1 st system frame number SFN.

Second, when sending SG in E-RGCH channel of service cell, UE receives first E-DCH control information (SG) on j sub-frame of E-RGCH frame in i system frame number SFN, then takes effect on j sub-frame of E-DPDCH frame in i +1 system frame number SFN.

However, the above-mentioned technique does not consider the issue of taking the rank value indicating that the UE adopts the single-stream mode or the single-stream mode and the effect of the secondary stream related information for determining the size of the secondary stream transmission data block according to the main stream SG into consideration. The receiving of the secondary stream related information from the base station includes: the ratio of the main stream information to the auxiliary stream information or the difference between the main stream information and the auxiliary stream information;

the main stream information comprises one or a combination of the following information: the main stream signal-to-interference-and-noise ratio, the main stream signal-to-noise ratio, the main stream receiving power and the main stream serving grant value index number, and the auxiliary stream information comprises one or a combination of the following information: the auxiliary stream signal-to-interference-and-noise ratio, the auxiliary stream signal-to-noise ratio, the auxiliary stream receiving power and the auxiliary stream service authorization value index number.

Therefore, in order to achieve the effect of multi-information synchronization, the embodiment of the invention achieves the effect of information synchronization by determining the timing and the effect time of each channel, and avoids the problem of uplink transmission efficiency reduction caused by the fact that information does not take effect at the same time.

Fig. 2 is a flowchart of an uplink data transmission method according to an embodiment of the present invention, and as can be seen from the diagram, the method includes:

step S201, receiving Rank value from a base station;

specifically, the base station determines that the current user terminal is suitable for single-stream data transmission or double-stream data transmission according to the network condition, that is, determines the Rank value.

Step S202, determining the sending mode of the user terminal according to the Rank value;

specifically, the user terminal determines that data should be sent to the uplink channel in a single-stream mode or a dual-stream mode currently according to the obtained Rank value. The dual stream means that two transmitting antennas of the main stream and the auxiliary stream are used for simultaneously transmitting data, and the single stream is only used for transmitting data by the main stream antenna.

For example, when the Rank value is 1, the ue transmits data in a single stream mode, and when the Rank value is 2, the ue transmits data by combining the primary and secondary streams.

Step S203, according to the determined transmission mode, transmitting data to an uplink channel.

Specifically, the UE may receive a serving grant SG via an E-AGCH channel, or a serving E-RGCH. The service authorization SG is that a base station measures the current real-time load through the change of the network state where the UE is located, compares the current real-time load with a target load, determines the current maximum power which can be transmitted by the UE through a load control algorithm, and transmits the maximum power to the UE in the form of SG so as to control the transmitting power of the UE. The UE determines the length of the currently transmitted data block according to the obtained SG, and adopts the power authorized by the base station for transmission, so that the load of a network receiving end is ensured not to exceed the target load, the interference level of the UE to the network is controlled, and the performance of the network is ensured. In the dual-stream mode, the UE calculates the SG of the secondary stream according to the main stream SG and the secondary stream related information, and determines the data block and the transmission power of the secondary stream.

Specifically, the UE determines that uplink data transmission is currently performed in a single stream or a dual stream according to the Rank value, and acquires a main stream transmission power and a data block size according to the SG.

In the single-stream mode, the user terminal determines the transmission power and the data block size sent by the single stream according to the grant SG of the main stream service. And in the dual-stream mode, acquiring service authorization information of the auxiliary stream according to the currently latest received auxiliary stream related information or the auxiliary stream related information which is valid together with the currently latest received auxiliary stream related information or the auxiliary stream related information, and acquiring the size and the transmitting power of the uplink data transmission data block of the auxiliary stream according to the auxiliary stream service authorization.

By adopting the embodiment, the UE determines to send data in a single-stream or double-stream mode after determining that the Rank value takes effect according to the received Rank value, so that the user terminal can convert the sending mode according to the state of the network, and the problems of poor transmission quality and efficiency caused by improper sending mode when the network condition is poor are avoided.

Fig. 3 is a flowchart of an uplink data transmission method according to another embodiment of the present invention, and as can be seen from the diagram, the method includes:

step S301, obtaining service authorization SG through a first dedicated channel;

specifically, the first dedicated channel may be an E-AGCH channel or a serving E-RGCH. If the former, the effective time of the SG is obtained according to the formulas (1) and (2), and if the latter, the SG is obtained according to the above-mentioned rule.

Step S302, obtaining the auxiliary stream related information and the Rank value through a second special channel;

specifically, the second dedicated Channel is a newly designed Secondary stream related information and Rank Indication Channel (SRICH), and a slot format of the second dedicated Channel is the same as or similar to three channels, i.e., F-TPICH, E-RGCH, and E-AGCH. However, data transmitted by the SRICH channel can only be received by UEs indicating upper phase MIMO, and the secondary stream related information and Rank information are transmitted in such a channel.

The frame offset of the SRICH channel is specifically a frame offset of the E-AGCH or a frame offset of the E-RGCH of the serving cell. Tau is_SRICH＝τ_E-AGCHOr τ_E-RGCH

Step S303, obtaining the common effective time of the SG, the Rank value and the auxiliary stream related information.

Specifically, the secondary stream related information is defined to be the same as the effective time of the Rank value, and the effective time is equal to the SG effective time.

For example, if the SG is transmitted in the E-AGCH, the UE receives the secondary stream related information and the Rank value on a j-th subframe of a second Dedicated channel SRICH frame with a system frame number i, where the uplink E-DCH channel transmission time is a t-th subframe time of an uplink enhanced Dedicated Physical data channel (E-DCH) frame in an i + s system frame number. Specifically, the values of s and t can be obtained with reference to the formulas (1), (2).

Wherein tau is_DPCH，nIs the frame offset of the nth Dedicated Physical Channel (DPCH), and when the downlink Fractional Dedicated Physical Channel (F-DPCH) is configured, the DPCH frame offset τ in the formula_DPCH，nF-DPCH frame offset τ_F-DPCH，n

And if the SG is sent by an E-RGCH of a serving cell, the UE receives the auxiliary stream related information and the Rank value on a j subframe of a second dedicated channel frame with a system frame number i, the uplink E-DCH transmission time is the j subframe time of an E-DPDCH frame in an i +1 system frame number, and i and j are positive integers.

That is, the E-DCH control information (SG) received at the jth sub-frame of the SRICH frame in the ith system frame number SFN takes effect at the jth sub-frame of the E-DPDCH frame in the (i + 1) th system frame number SFN.

And step S304, after the simultaneous effective time of the SG, the auxiliary stream related information and the Rank value is reached, transmitting data to an uplink channel according to the SG, the Rank value and the auxiliary stream related information.

Specifically, referring to fig. 4, it is a usage status reference diagram of the uplink data transmission method according to the embodiment of the present invention, and as can be seen from the diagram, the indication information received at the time X is a combination of three indication information used by the UE after the indication information is valid at the time Y.

For example, in the scenario shown in fig. 4, where Rank is 2, the UE transmits data in a dual-stream mode, where the transmission power of the primary stream refers to SG, and the secondary stream refers to the secondary stream related information and SG. If Rank is 1, the UE adopts the single stream transmission mode, and if there is no auxiliary stream, the auxiliary stream related information is not needed.

Before the next SG and Rank take effect, that is, before the next E-DCH transmission time comes, the UE sends data in the mode indicated by the Rank value that is in effect, taking fig. 4 as an example, the Rank ═ 2 UE sends data in the dual-stream mode where the primary stream and the secondary stream jointly perform, where the primary stream transmission power is based on the SG indication, and the secondary stream indication information is obtained by calculating with the primary stream service grant SG and the secondary stream related information ═ K7 as common parameters, for example, with the primary stream service grant SG index number-K7 as the secondary stream SG index number. In practical application, the index value in the list can be used for searching, and the transmitting power executed by the main stream/auxiliary stream can be obtained after the relevant information of the SG and the auxiliary stream is received.

As for the received Rank value, the base station may send in an explicit or implicit manner, where the explicit sending indicates to directly notify the UE, where the Rank is 1 or 2, the Rank and the auxiliary stream related information are sent in a second dedicated channel through joint coding, and when a frame offset of the second dedicated channel is the E-AGCH frame offset, a channel format of the second dedicated channel is the same as or similar to that of the E-AGCH channel, the second dedicated channel may send an information amount of n + p + m bits, or may send information of n + m bits, where n is a bit value carrying the Rank information, p is a bit value carrying other predefined information, and m is a bit value carrying the auxiliary stream related information. n + p + m or n + m should be less than or equal to 6bits, n, p, m are positive integers. For example, when n is 1, p is 1, and m is 4, 1bit is used to carry Rank information, 1bit is used to carry authorization range information, and 4bits is used to carry information related to the auxiliary stream.

The implicit transmission indicates other reference values on the second dedicated channel, for example, when the secondary stream related information is 0, it is determined that Rank is 1.

By adopting the embodiment, the UE can use the auxiliary stream related information, the SG and the Rank indication which take effect at the same time to transmit data, and the problem of transmission quality reduction or transmission efficiency reduction caused by asynchronous indication information can be avoided.

Fig. 5 is a flowchart of an uplink data transmission method according to another embodiment of the present invention, and as can be seen from the diagram, the method includes:

step S501, obtaining service authorization SG through a first dedicated channel;

Step S502, obtaining the auxiliary stream related information and the Rank value through a second special channel;

Step S503, obtaining a second common uplink transmission time of the SG information and the auxiliary stream related information, and updating the received Rank value according to a preset time period.

Specifically, the second common uplink transmission time is a time at which the SG and the secondary stream related information become effective after being received.

The secondary stream related information is the same as the valid time of the SG, that is, when the frame offset of the SRICH is the frame offset of the E-AGCH, the second common uplink transmission time of the SG information and the secondary stream related information is specifically:

receiving auxiliary stream related information from a base station on a jth subframe of an SRICH frame with a system frame number i, wherein the second common uplink transmission time is the t subframe time of an E-DPDCH frame in an i + s system frame number;

wherein i and j are positive integers, wherein tau is_DPCH，nIs the frame offset, τ, of the nth dedicated physical channel DPCH_DPCH，nEqual to tau applied in E-AGCH_DPCH，n。

And when the frame offset of the SRICH is the frame offset of the E-RGCH of the serving cell, the second common uplink transmission time of the SG information and the secondary stream related information is specifically:

and receiving the auxiliary stream related information on a jth subframe of an SRICH frame with a system frame number i, wherein a second common uplink transmission moment is the jth subframe moment of an E-DPDCH frame in the ith +1 system frame number, and i and j are positive integers.

Meanwhile, the user equipment UE continuously updates the received Rank value according to a predetermined time period, which is usually a subframe TTI period, so that when the second common uplink transmission time of the SG and the auxiliary stream related information arrives, the Rank value received by the latest TTI is used as an effective Rank value to determine the current transmission mode.

And step S504, transmitting data to an uplink channel according to the SG and the Rank value.

For example, if Rank received by the UE in the closest TTI is 1, the UE transmits data in the single-stream mode, and therefore, at this time, the current primary stream transmission power and the data block size are determined by the currently valid primary stream service grant SG, and the secondary stream related information reaches the uplink transmission time, but the secondary stream is not transmitted in the single-stream mode, and therefore, the service grant of the secondary stream does not need to be determined by the secondary stream related information.

If Rank received by the closest TTI of the UE is 2, the user terminal sends data in a dual-stream mode, and therefore, the current main stream sending power and the size of a data block are determined by the currently effective main stream service authorization SG; and determining the service authorization of the auxiliary stream through the auxiliary stream related information, and acquiring the transmitting power and the data block size of the auxiliary stream through the auxiliary stream service authorization.

By adopting the embodiment, the sending mode of the UE can be determined according to the recently received indication of the Rank value, and the problem that the data transmission quality is reduced because the network condition is changed and the sending mode is still determined according to the wrong Rank value when the SG, the Rank value and the auxiliary stream related information are waited to be effective is solved.

Fig. 6 is a flowchart of an uplink data transmission method according to another embodiment of the present invention, and as can be seen from the diagram, the method includes:

step S601, obtaining service authorization SG through a first dedicated channel;

Step S602, obtaining the auxiliary stream related information and the Rank value through a second special channel;

Step S603, obtaining an uplink transmission time of the SG information, and updating the received Rank value and the auxiliary stream related information according to a preset time period.

The SG validation time is the same as that of the previous embodiment, and therefore, the description thereof is omitted.

The difference from the foregoing embodiment is that, in this embodiment, the UE continuously updates the received Rank value and the secondary stream related information according to a preset time period, where the preset time period is usually one subframe TTI, that is, 2 mm.

When the upstream transmission time of the main stream service authorization SG, namely the effective time comes, the Rank value and the auxiliary stream related information received by one TTI closest to the effective time are used as the currently effective Rank value and the currently effective auxiliary stream related information, and the upstream transmission is carried out according to the currently effective SG, the Rank value and the auxiliary stream related information.

Step S604, transmitting data to the uplink channel according to the SG and the Rank value.

For example, when the primary stream service grant SG takes effect, if the nearest TTI receives Rank equal to 1, the UE transmits data in the single stream mode, and therefore, at this time, the current primary stream transmission power and data block size are determined by the currently effective primary stream service grant SG, and the secondary stream related information is transmitted in the single stream mode without the secondary stream, so that the service grant of the secondary stream does not need to be determined by the secondary stream related information.

If Rank received by the closest TTI of the UE is 2, the user terminal sends data in a dual-stream mode, and therefore, the current main stream sending power and the size of a data block are determined by the currently effective main stream service authorization SG; and determining the service authorization of the auxiliary stream according to the auxiliary stream related information received closest to one TTI, and acquiring the transmission power and the data block size of the auxiliary stream according to the auxiliary stream service authorization.

By adopting the embodiment, the sending mode of the UE can be determined according to the recently received indication of the Rank value, and the problem that the data transmission quality is reduced because the network condition is changed and the sending mode is still determined according to the wrong Rank value when the SG, the Rank value and the auxiliary stream related information are waited to be effective is solved. And determining the auxiliary flow transmitting power according to the auxiliary flow related information received by the closest TTI, thereby improving the transmission efficiency.

Fig. 7 is a flowchart of an uplink data transmission method according to another embodiment of the present invention, and as can be seen from the diagram, the method includes:

step S701, obtaining service authorization (SG) through a first dedicated channel;

Step S702, acquiring auxiliary stream related information and a Rank value through a second dedicated channel;

The frame offset of the SRICH channel is specifically the frame offset of the E-AGCH, or the frame offset of the E-AGCHFrame offset of E-RGCH of serving cell. Tau is_SRICH＝τ_E-AGCHOr τ_E-RGCH。

Step S703 is to obtain a third common uplink transmission time of the SG information and the Rank value, and update the received auxiliary stream related information according to a preset time period.

Specifically, when the frame offset of the SRICH is the frame offset of the E-AGCH, the third common uplink transmission time of the SG information and the Rank value is specifically:

receiving the Rank value from the base station on a j subframe of an SRICH frame with a system frame number i, wherein the third common uplink transmission time is the t subframe time of an E-DPDCH frame in the i + s system frame number;

wherein i and j are positive integers, wherein tau is_DPCH，nIs the frame offset, τ, of the nth DPCH_DPCH，nEqual to tau applied in E-AGCH_DPCH，n。

And when the frame offset of the SRICH is the frame offset of the E-RGCH of the serving cell, the third common uplink transmission time of the SG information and the Rank value is specifically:

and receiving a Rank value on a j subframe of an SRICH frame with a system frame number of i, wherein the third common uplink transmission time is the j subframe time of an E-DPDCH in the i +1 system frame number, and i and j are positive integers.

In this embodiment, the UE continuously updates the received Rank value according to a preset time period, where the preset time period is usually one subframe TTI, that is, 2 mm.

Step S704, according to the SG, the Rank value transmits data to the uplink channel.

And when the common uplink transmission time of the main stream service authorization SG and the auxiliary stream related information, namely the effective time comes, taking the Rank value received by one TTI closest to the effective time as the currently effective Rank value, and performing uplink transmission according to the currently effective SG, the Rank value and the auxiliary stream related information.

For example, when the primary stream service grant SG takes effect, if the nearest TTI receives Rank equal to 1, the UE transmits data in the single stream mode, and therefore, at this time, the current primary stream transmission power and data block size are determined by the currently effective primary stream service grant SG, and the secondary stream related information is already in effect, but the secondary stream is not transmitted in the single stream mode, and therefore, the service grant of the secondary stream does not need to be determined by the secondary stream related information.

If Rank received by the closest TTI of the UE is 2, the user terminal sends data in a dual-stream mode, and therefore, the current main stream sending power and the size of a data block are determined by the currently effective main stream service authorization SG; and determining the service authorization of the auxiliary stream according to the currently effective auxiliary stream related information, and acquiring the transmitting power and the data block size of the auxiliary stream according to the auxiliary stream service authorization.

Fig. 8 is a flowchart of an uplink data transmission method according to another embodiment of the present invention, and as can be seen from the diagram, the method includes:

step S801, obtaining service authorization SG and Rank value through a first dedicated channel;

specifically, after the UE accesses the network and the network status changes, the base station generates a main stream service grant SG value and Rank information according to the current network environment, and may send the main stream service grant SG and Rank information to the UE through two E-DCH franchises, i.e. an E-AGCH channel and a service E-RGCH channel.

If the UE receives the indication information through the latter, the SG effective time is obtained according to the formulas (1) and (2).

Step S802, obtaining the auxiliary flow related information through a second dedicated channel;

specifically, the dedicated Channel is a Secondary related information Channel (SICH) that is newly designed. The data transmitted by the SICH can only be received by the UE supporting uplink MIMO, and is used for transmitting the auxiliary stream related information. And the UE receives the auxiliary stream related information generated by the network side according to the uplink transmission channel environment and the current network condition through the SICH.

The SICH channel frame offset is specifically the frame offset of the E-AGCH or the frame offset of the E-RGCH of the serving cell. Tau is_SICH＝τ_E-AGCHOr τ_E-RGCH。

Step S803, obtaining the common effective time of the service authorization SG and the Rank value;

specifically, Rank is transmitted in the same channel as SG, so the effective time is the same, that is, the transmission time of the uplink enhanced dedicated channel corresponding to the Rank value and the information related to the secondary stream from the base station are the same, if received in the E-AGCH channel, the effective time can be calculated by using the formulas (1) and (2), and if received in the E-RGCH of the serving cell, the effective time is calculated according to the E-RGCH standard.

Step S804, updating the auxiliary flow related information received according to a preset time period;

specifically, the currently received secondary stream related information is updated once every other transmission time interval TTI, and a closest secondary stream related information before the common validation time of the received serving grant SG and the Rank value is used as the currently available secondary stream related information.

And step S805, transmitting data to an uplink channel according to the currently effective SG, the Rank value and the relevant information of the available auxiliary stream.

Specifically, the common effective time of the service grant SG and the Rank value is used as the current effective time, the auxiliary stream related information received most recently with the common effective time is used as the current available auxiliary stream related information, and the three are used as reference values to transmit data to the uplink data channel.

Fig. 9 is a state reference diagram of the uplink data transmission method according to the foregoing embodiment, and it can be seen from the diagram that the SG and the Rank value received at the time X are valid at the time Y, while the secondary stream related information received at the time Y is K5, and the secondary stream related information received at the time X is K2, and then the secondary stream related information received at the time Y and the SG and the Rank value valid at the time Y are used as indication information.

Before the next SG and Rank take effect, the UE sends data in the mode indicated by the Rank value that is in effect, taking fig. 9 as an example, when Rank is 2, the UE sends data in a dual-stream mode where a primary stream and a secondary stream jointly proceed, where the primary stream transmission power is based on the SG indication, and the secondary stream indication information is obtained by calculating with a primary stream service grant SG and secondary stream related information K5 as common parameters, for example, a primary stream service grant SG-K5 is used as a secondary stream SG. In practical application, the list index value may be used to search, and the transmission power to be executed may be obtained after receiving the SG and the auxiliary stream related information.

The implicit transmission indicates another reference value of the second dedicated channel, for example, when the secondary stream related information is 0, it is determined that Rank is 1.

Fig. 10 is a schematic diagram of a state when the validation time Rank indicates the single stream mode, and it can be seen from the diagram that at this time, when the current M time Rank is 1, no auxiliary stream related information exists, but when the validation time is that the Rank sent by the P time is 2, the auxiliary stream related information must be required to be a reference value, and therefore, the auxiliary stream related information received in the previous subframe is used as the current available auxiliary stream related information. That is, it is assumed that the validation indication information at this time is the secondary stream related information value K7 in the previous subframe, and the SG adopts the dual stream transmission mode.

By adopting the embodiment, the UE can obtain the updating condition of each transmission time interval TTI, so that the UE can determine the transmission condition of the current channel in real time and obtain more accurate auxiliary stream authorization.

An uplink data transmission indication method provided by an embodiment of the present invention is described below from a base station side, fig. 8 is a flowchart of the method, and as can be seen from the diagram, the method includes:

step S1101, generating SG, auxiliary flow related information and a Rank value according to current network state change information;

specifically, the base station measures the current real-time load, compares the current real-time load with a target load, determines the current maximum power which can be transmitted by the UE through a load control algorithm, and controls the transmission power of the UE by representing the maximum power in the form of SG. The UE may determine the currently transmitted data block length from the obtained SG.

In uplink MIMO application, the same load control mechanism is also needed to ensure network performance, and the base station determines the maximum SG of the user by considering the power load of the primary and secondary streams at the same time, and also determines the number of data streams rank. If the dual stream mode is adopted for transmission, after the SG of the main stream is determined, the SG of the auxiliary stream can be calculated through the auxiliary stream related information and the SG of the main stream, and therefore the auxiliary stream related information also needs to be generated.

Step S1102, a service authorization (SG) and a Rank value are sent to a user terminal (UE) through a downlink channel;

specifically, the generated indication information is sent to the UE through different channels, so that the UE can adjust the sending power and the sending mode according to the information after receiving the indication information, and when the UE is indicated to send in the dual-stream mode, the UE needs to send the information related to the auxiliary stream.

Step S1103, after receiving the service grant SG and the Rank value obtained by the UE, performs uplink enhanced dedicated channel transmission according to the Rank value and the service grant SG information at the corresponding uplink enhanced dedicated channel transmission time.

Specifically, before the next SG and Rank are in effect, that is, before the next E-DCH transmission time comes, the UE transmits data in the mode indicated by the Rank value in effect. If the single-stream mode is adopted, the user equipment UE only refers to the SG and the Rank, and if the double-stream mode is adopted, the auxiliary stream related information is also required to be referred to obtain the auxiliary stream indication information.

Taking fig. 9 as an example, if Rank is 2, the UE transmits data in a dual-stream mode performed by the primary stream and the secondary stream together, where the primary stream transmission power is based on the SG indication, and the secondary stream indication information is obtained by calculating using the primary stream service grant SG and the secondary stream related information K5 as a common parameter, for example, the primary stream service grant SG-K5 is used as the secondary stream SG. And the base station receives the data sent by the user terminal UE according to the instruction.

Through the embodiment, the base station can send and receive service authorization (SG), auxiliary stream related information and the Rank value to the UE, so that the base station can adjust the transmission mode and power and improve the transmission efficiency and quality.

Fig. 12 is a flowchart of an embodiment of S1102 in the foregoing embodiment, and as can be seen from the diagram, step S803 includes:

step S1201, transmitting an SG through a first dedicated channel;

Step S1202, the secondary stream related information and the Rank value are transmitted through the second dedicated channel.

Specifically, the dedicated Channel is a newly designed secondary stream related information and Rank Indication Channel (SRICH), and a slot format of the Channel is the same as or similar to three channels, i.e., F-TPICH, E-RGCH, and E-AGCH. However, data transmitted by the SRICH channel can only be received by UEs indicating upper phase MIMO, and the secondary stream related information and Rank information are transmitted in such a channel.

The frame offset of the SRICH channel is specifically a frame offset of the E-AGCH or a frame offset of the E-RGCH of the serving cell. Tau is_SRICH＝τ_E-AGCHOr τ_E-RGCH。

After receiving the indication message, the UE may perform upload data transmission in the state indicated by the indication information after all the indication information is in effect synchronously, so as to avoid the problems of reduced transmission quality and reduced transmission efficiency caused by the asynchronous effect of the indication information.

Or, the UE may also update the Rank value received in the last TTI when the effective time of the received SG and the secondary stream related information arrives, and determine the current transmission mode by using the Rank value as an indication.

The UE may also update the Rank value and the secondary stream related information received in the latest TTI when the received SG comes into effect, and determine the current transmission mode by using the Rank value as an indication. Particularly, when the Rank value is 2, the transmission power of the auxiliary stream and the size of the data block are determined by using the auxiliary stream related information received in the latest TTI as an indication, in addition to the effective SG as an indication to transmit the main stream data.

The UE may also update the received secondary stream related information in the latest TTI when the common effective time of the received S and Rank values comes, and determine the current transmission mode by using the effective Rank value as an indication. Particularly, when the Rank value is 2, the transmission power of the auxiliary stream and the size of the data block are determined by using the auxiliary stream related information received in the latest TTI as an indication, in addition to the effective SG as an indication to transmit the main stream data.

Fig. 13 is a flowchart of another embodiment of S1102 in the embodiment shown in fig. 11, and as can be seen from the diagram, step S802 includes:

step S1301, SG and Rank value are obtained through a first special channel;

If the UE receives the indication information through the latter, the effective time of the SG is obtained according to the formulas (1) and (2), and if the UE receives the indication information through the latter, the effective time of the SG is obtained according to the E-RGCH channel specification of the serving cell.

Step S1302, obtaining the auxiliary stream related information through a second dedicated channel;

specifically, the dedicated Channel is a Secondary related information Indication Channel (SICH) that is newly designed. The data transmitted by the SICH can only be received by the UE supporting uplink MIMO, and is used for transmitting the auxiliary stream related information. And the UE receives the auxiliary stream related information generated by the network side according to the uplink transmission channel environment and the current network condition through the SICH.

The SICH channel frame offset is specifically the frame offset of the E-AGCH, or the frame offsetThe frame offset of the E-RGCH of the serving cell. Tau is_SICH＝τ_E-AGCHOr τ_E-RGCH。

It should be clear that in the foregoing embodiments, the second dedicated channel SICH is only named based on functions, and should not be construed as limiting the core idea of the technical solution provided by the present invention.

In the above embodiments, the Rank value may be sent by the base station in an explicit or implicit manner, where explicit sending indicates that the UE is directly notified that the Rank is 1 or 2, and implicit sending indicates that the Rank is 1 using another reference value, for example, when the secondary flow related information is 0.

Fig. 14 is a block diagram of an uplink data transmission apparatus according to an embodiment of the present invention, where the uplink data transmission apparatus may include, but is not limited to, a UE indicating UL MIMO. The device comprises:

a receiving unit 141, configured to receive current service grant SG information and a Rank value;

an obtaining unit 142, configured to obtain the service grant SG and the uplink E-DCH transmission time of the Rank value;

a transmitting unit 143, configured to perform uplink enhanced dedicated channel transmission according to the Rank value and the service grant SG information at the uplink enhanced dedicated channel transmission time.

The receiving unit 141 receives not only the SG and Rank values but also the auxiliary stream related information in the dual stream transmission mode. Specifically, service authorization SG can be obtained through an E-AGCH channel or a service E-RGCH, and auxiliary stream related information and a Rank value can be obtained through a designed SRICH dedicated channel; service authorization SG and Rank value can be obtained through an E-AGCH channel or a service E-RGCH, and the auxiliary stream related information can be obtained through a SICH special channel.

If the receiving unit 141 acquires the indication information in the former manner, the acquiring unit 112 acquires the common validation time for acquiring the service grant SG, the Rank value, and the secondary stream related information, and then transmits data to the uplink channel according to the service grant SG, the Rank value, and the secondary stream related information after the simultaneous validation time for acquiring the service grant SG, the Rank value, and the secondary stream related information is reached.

In addition, when the time of validity of the received SG and the secondary stream related information arrives, the UE may update the Rank value received in the last TTI, and determine the current transmission mode by using the Rank value as an indication.

The UE may also update the latest TTI that receives the secondary stream related information when the common effective time of the received SG and Rank values comes, and determine the current transmission mode by using the Rank value that comes into effect at this time as an indication. Particularly, when the Rank value is 2, the transmission power of the auxiliary stream and the size of the data block are determined by using the auxiliary stream related information received in the latest TTI as an indication, in addition to the effective SG as an indication to transmit the main stream data.

If the receiving unit 141 acquires the indication information in the latter manner, the acquiring unit 142 acquires the common effective time of the service grant SG and the Rank value through the E-DCH franchise channel frame offset, and updates the auxiliary stream related information received according to the preset time through an updating unit; and transmitting data to an uplink channel according to the currently effective SG, the Rank value and the auxiliary stream related information received in the latest preset time between the current effective time and the next effective time after the transmission time of the uplink enhanced dedicated channel.

Fig. 15 is a structural diagram of an uplink data transmission indicating apparatus provided by the present invention, where the apparatus may include, but is not limited to, a base station, and specifically, as shown in fig. 12, the apparatus includes:

an indication information generating unit 151, configured to generate a downlink channel according to the current network state change information, and send information related to a received service grant SG auxiliary stream and a Rank value to a user equipment UE;

A data receiving unit 153, configured to perform uplink enhanced dedicated channel transmission according to the Rank value and the service grant SG information at the corresponding uplink enhanced dedicated channel transmission time after receiving that the user equipment UE acquires the service grant SG and the Rank value.

Specifically, the base station measures the current real-time load, compares the current real-time load with the target load, determines the maximum power that the UE can currently transmit by using the load control algorithm through the indication information generating unit 121, and controls the transmission power of the UE by representing the maximum power in the form of SG. The UE can determine the length of the data block currently transmitted according to the obtained SG, and simultaneously determines the maximum SG of the user by considering the power load of the primary stream and the secondary stream, and also determines the rank number of the data stream.

If the UE is allowed to adopt the dual-stream mode invention, the auxiliary stream related information also needs to be generated, and after the SG of the main stream is determined, the SG of the auxiliary stream can be calculated through the auxiliary stream related information and the SG of the main stream.

The indication information sending unit 122 may send the generated indication information to the UE through different channels, so that the UE can adjust the sending power and the transmission mode according to the information after receiving the indication information.

For example, the service grant SG is transmitted through the E-AGCH channel or the service E-RGCH, the secondary stream related information and the Rank value are transmitted through the SICH, or the service grant SG and the Rank value are acquired through the E-AGCH channel or the service E-RGCH and the secondary stream related information is acquired through the dedicated channel SICH.

The data receiving unit 153 receives data transmitted to the uplink channel according to the Rank value, the service grant SG information, and the available auxiliary stream related information indication between the current time of taking effect and the next time of taking effect simultaneously after the user equipment UE obtains the service grant SG and the Rank value.
