The above described objects, features, and advantages of the embodiments of the present invention will become more apparent and understood. Give further details.

Before the description of the uplink data transmission embodiment of the present invention is described, the terminal is not used first. Referring to FIG. 1, a schematic diagram of an uplink MIMO transmission structure of a UMTS system:

In FIG. 1, the uplink transmission is divided into a primary precoding transmission and a secondary precoding transmission, wherein the physical channel transmitted on the primary precoding includes a primary DPCCH (Dedicated Physical Control Channel), and an E-DPDCH (E-DCH (E-DCH ( Enhanced Dedicated Channel, Dedicated Physical Data Control Channel, E-DCHCH (E-DCH (Enhanced Dedicated Channel) Dedicated Physical Control Channel, E-DCH Dedicated Physics Control channel) and other traditional data and control channels, such as HS-DPCCH (High-Speed Dedicated Physical Control Channel) and DPDCH (Dedicated Physical Data Channel); The physical channel includes a secondary DPCCH, a secondary E-DPDCH, and a secondary E-DPCCH. The physical channel transmitted on the primary precoding and the physical channel transmitted on the secondary precoding are respectively subjected to spreading, accumulating and scrambling processing to generate a precoding vector, where W1 and W2 represent the primary precoding vector, and W3 and W4 represent the secondary precoding. The code vector, and W3 are accumulated and transmitted through the antenna 1, and W2 and W4 are accumulated and transmitted through the antenna 2.

In the embodiment of the present invention, the rank refers to the rank of the channel, and the information of the number of mutually independent channels that can be distinguished by the rank by the rank, and the rank type includes rank1 and rank2. With reference to FIG. 1, when the rank is rank1, the physical channel transmitted by the UE includes the primary E-DPCCH, the primary E-DPDCH, and the secondary DPCCH. When the rank is rank2, the physical channel transmitted by the UE includes the primary E_DPCCH, the secondary E_DPCCH, and the E. -DPDCH, secondary E-DPDCH and secondary DPCCH. In the embodiment of the present invention, the NB determines the UE to use by combining the rank indication information carried by the UE on the secondary DPCCH or the secondary E-DPCCH in order to overcome the defect that the NB is easy to receive the error rank. r ank , which can improve the accuracy of NB to determine rank, thereby improving system performance.

Referring to FIG. 2, it is a flowchart of the first embodiment of the rank determining method of the present invention:

Step 201: The NB receives the channel sent by the UE.

In this embodiment, when the rank is rank1, the UE may transmit the primary E-DPCCH, the primary E-DPDCH, and the secondary DPCCH in the initial transmission and the retransmission, and may also transmit the primary E_DPDCH, the secondary E-DPCCH, and the retransmission. Auxiliary DPCCH; When rank is rank2, the physical channels transmitted by the UE during initial transmission and retransmission include a primary E-DPCCH, a secondary E-DPCCH, a primary E-DPDCH, a secondary E-DPDCH, and a secondary DPCCH. Step 202: Determine a rank used by the UE according to the rank indication information carried on the at least one channel of the received channel.

Regardless of whether the UE uses rank1 or rank2, the uplink transmission channel includes the secondary DPCCH, so the secondary DPCCH can be used to carry the rank indication information. In addition, when the UE uses the rank1 for retransmission, or the rank2, the secondary E-DPCCH can be used. The rank indication information is carried.

Therefore, the NB can use the following methods when determining the rank used by the UE:

The first mode may be as follows: Obtaining the rank indication information of the non-pilot bit bearer on the secondary DPCCH in the received channel, where the rank indication information indicates different ranks by different bit values, and demodulates the rank indication. Information, determining the rank used by the UE according to the demodulation result; or

The second mode may be as follows: detecting a channel type of a channel sent by the UE, obtaining a first rank information according to the detection result, acquiring rank indication information carried on the at least one channel, and obtaining a second rank information, comparing the first The rank information and the second rank information determine the rank used by the UE according to the result of the comparison; or

The third mode may be as follows: detecting a channel type of a channel sent by the UE, where the channel type includes at least a secondary DPCCH and a secondary E-DPCCH, and acquiring first rank information and second respectively carried on the secondary DPCCH and the secondary E-DPCCH. The rank information compares the first rank information and the second rank information, and determines a rank used by the UE according to the result of the comparison.

It can be seen from the foregoing embodiment that the UE carries the indication information of the used rank on the transmitted at least one channel, so that the NB can improve the accuracy of determining the rank according to the rank indication information, thereby ensuring that the UE and the NB use the consistent rank. Data demodulation to improve system performance.

Referring to FIG. 3, it is a flowchart of a second embodiment of the rank determining method according to the present invention. The embodiment shows a process of determining rank based only on the rank indication information of the secondary DPCCH bearer:

Step 301: The NB receives the channel sent by the UE.

Step 302: The NB acquires the rank indication information of the non-pilot bit 7 on the secondary DPCCH.

The UE sends the secondary DPCCH to the NB regardless of whether it uses rank1 or rank2. The rank indication information carried by the non-pilot bits on the secondary DPCCH can be as shown in Table 1 below: Table 1

As can be seen from the above Table 1, the rank indication information is represented by information bits, that is, when the information bit is "11", corresponding to rank2, and when the information bit is "00", it corresponds to rankl.

It should be noted that, in addition to the correspondence between the information bits and the rank as shown in Table 1, it may be defined that if the information bit is 00, the corresponding rank is rank2, and the information bit is 11, the corresponding rank is rankl, as long as The rank can be distinguished by the different bit information carried by the non-pilot bits on the secondary DPCCH, which is not limited in this embodiment of the present invention.

Step 303: The NB demodulates the rank indication information, and determines the rank used by the UE according to the demodulation result. According to the relationship between the information bits and the rank shown in Table 1 above, when the bit value on the secondary DPCCH received by the NB demodulation is 11, the rank used by the UE is determined to be rank2, and the NB demodulates the received secondary DPCCH. When the bit value is 00, it is determined that the rank used by the UE is rankl.

The foregoing embodiment is configured to carry the rank indicated by the UE on the secondary DPCCH, so that the NB does not need to detect the channel reception condition, and can directly obtain the rank corresponding to the UE according to the rank indicated by the UE carried on the secondary DPCCH, thereby improving the NB to determine the rank. Accuracy, improve the data reception performance of the system.

Referring to FIG. 4, it is a flowchart of a third embodiment of the rank determining method according to the present invention. The embodiment shows a process for determining rank by detecting a channel and carrying a rank indicating information:

Step 401: The NB receives the channel sent by the UE.

Step 402: The NB detects the channel type of the channel sent by the UE. If the primary and secondary E-DPCCHs are detected at the same time, step 403 is performed. If the primary E-DPCCH is detected and the secondary E-DPCCH is not detected, step 410 is performed.

Step 403: The NB obtains the first rank information according to the result of detecting the primary and secondary E-DPCCH. When the NB detects the primary and secondary E-DPCCHs, according to the determining manner of the prior art, the obtained first rank information corresponds to the indicated rank as rank2. Step 404: The NB demodulates the rank indication information of the non-pilot bit bearer on the secondary DPCCH to obtain the second rank information.

The manner in which the non-pilot bit on the secondary DPCCH carries the rank indication information in this embodiment may be consistent with the foregoing second embodiment, and details are not described herein again.

The rank corresponding to the second rank information carried by the non-pilot bit on the secondary DPCCH may be rank1 or rank2.

Step 405: Determine whether the first rank information and the second rank information are consistent. If yes, execute step 406; otherwise, perform step 407.

Step 406: The NB determines that the rank used by the UE is rank2, and ends the current process.

Step 407: Determine whether the UE is currently in the power enhanced state. If not, go to step 408; otherwise, go to step 409.

The power boosting state (Boosting) indicates that the UE needs to perform power enhancement on certain channels. When the amount of data carried on some channels is greater than a preset threshold, it indicates that these channels need to be boosted (boost).

Step 408: The NB determines that the rank used by the UE is the rank indicated by the first rank information, and ends the current process.

Step 409: If the UE power is enhanced by the primary E-DPCCH and the secondary DPCCH, determine that the rank used by the UE is the rank indicated by the second rank information, and if the UE power enhances the primary E-DPCCH and the secondary E-DPCCH, determine the rank used by the UE. End the current flow for the rank indicated by the first rank information.

Step 410: The NB obtains the third rank information according to the result that the primary E-DPCCH is detected and the secondary E-DPCCH is not detected.

When the NB detects the primary E-DPCCH and does not detect the secondary E-DPCCH, according to the determining method in the prior art, the obtained third rank information corresponds to the indicated rank being rankl.

Step 411: The NB demodulates the rank indication information carried by the non-pilot bit on the secondary DPCCH to obtain the fourth rank information.

The fourth rank information carried by the non-pilot bit on the secondary DPCCH corresponds to the indicated rank may be rankl or rank2.

Step 412: Determine whether the third rank information and the fourth rank information are consistent. If yes, go to step 413; otherwise, go to step 414.

Step 413: The NB determines that the rank used by the UE is rank1, and ends the current process. Step 414: Determine whether the UE is currently in the power boost state. If yes, go to step 415; otherwise, go to step 416.

Step 415: The NB determines that the rank used by the UE is the rank indicated by the fourth rank information, and ends the current process.

Step 416: The NB determines that the rank used by the UE is the rank indicated by the third rank information, and ends the current process.

It should be noted that, in the foregoing embodiment, in step 402, a determination condition is that if the primary E-DPCCH is detected and the secondary E-DPCCH is not detected, step 41 0 is performed; when the determination condition is that if it is detected If the primary E-DPCCH is not detected and the primary E-DPCCH is not detected, step 41 0 may also be performed, and details are not described herein. That is, since the UE transmits the secondary DPCCH channel in any case, the rank information carried by the non-pilot bit on the secondary DPCCH channel can be used to determine the rank regardless of the judgment condition.

It can be seen that, by using the indication information of the rank used by the UE in the transmitted secondary DPCCH, the NB can determine the rank used by the UE according to the detection result of the channel according to the rank indication information, thereby improving the accuracy of determining the rank. Ensure that the UE and NB use the same rank for data demodulation, thereby improving system performance.

Referring to FIG. 5, it is a flowchart of a fourth embodiment of the method for determining rank according to the present invention. The embodiment shows another process for determining rank by detecting a channel and carrying rank indication information: Step 501: The NB receives a channel sent by the UE.

When the secondary E-DPCCH is received, the rank indication information may be carried by the happy bit of the secondary E-DPCCH. The rank indication information can be set using the correspondence shown in Table 2 below: Table 2

It should be noted that, in addition to the correspondence between the information bits and the rank as shown in Table 2, it may be defined that if the information bit is 0, the corresponding rank is 2, and when the information bit is 1, the corresponding rank is 1, as long as The different bit information carried by the happy bit of the secondary E-DPCCH can be used to distinguish the rank, which is not limited in this embodiment of the present invention. Step 502: If the primary E-DPCCH is detected and the secondary E-DPCCH is not detected, the step 508 is performed. If the secondary E-DPCCH is detected and the primary E-DPCCH is not detected, step 509 is performed.

Step 503: The NB obtains the first rank information according to the result of detecting the primary and secondary E-DPCCH. When the primary and secondary E-DPCCHs are detected by the NB, according to the determining manner of the prior art, the rank of the first rank information corresponding to the indication is rank2.

Step 504: The NB decodes the rank indication information carried by the happy bit on the secondary E-DPCCH, and obtains the second rank information.

The rank corresponding to the second rank information carried by the happy bit on the secondary E-DPCCH may be rank1 or rank2.

Step 505: Determine whether the first rank information and the second rank information are consistent. If yes, execute step 506; otherwise, go to step 507.

Step 506: The NB determines that the rank used by the UE is rank2, and ends the current process.

Step 507: The NB determines that the rank used by the UE is the rank indicated by the second rank information, and ends the current process.

Step 508: The NB determines that the rank used by the UE is rank 1, and ends the current process.

Step 509: The NB obtains the third rank information according to the result that the primary E-DPCCH is not detected by the secondary E-DPCCH.

When the NB detects the secondary E-DPCCH and does not detect the primary E-DPCCH, according to the determining method in the prior art, the obtained third rank information corresponds to the indicated rank being rankl.

Step 510: The NB decodes the rank indication information carried by the happy bit on the secondary E-DPCCH, and obtains the fourth rank information.

The fourth rank information carried by the happy bit on the secondary E-DPCCH may correspond to the rank indicated by rank1 or rank2.

Step 511: Determine whether the third rank information and the fourth rank information are consistent. If yes, execute step 512; otherwise, perform step 513.

Step 512: The NB determines that the rank used by the UE is rank1, and ends the current process.

Step 513: The NB determines that the rank used by the UE is the rank indicated by the fourth rank information, and ends the current process. It can be seen that, by using the indication information of the used rank on the transmitted secondary E-DPCCH, the NB can determine the rank according to the rank indication information according to the channel detection result, thereby improving the accuracy of determining the rank, and ensuring the UE. Data demodulation is performed with the same rank as NB, thereby improving system performance.
