The user equipment can flexibly select the order of filling the auxiliary stream and the main stream to perform data filling and then send the data of the main stream and the auxiliary stream. Since data is filled in order of priority from high to low, filling the main stream first allows high-priority data to be filled on the main stream. Relatively speaking, the reliability of the main stream is better than that of the auxiliary stream. Filling the main stream first can ensure the correctness of high-priority data transmission, but filling the main stream first will cause high-priority data and non-scheduled data to compete together. Mainstream available power, if there are more high-priority data, non-scheduled data cannot be sent. Therefore, filling the auxiliary stream first can allow high-priority data to be filled in the auxiliary stream first, so that high-priority data does not compete with non-scheduled data on the main stream, ensuring that both high-priority and non-scheduled data can be sent out.

In the above embodiment, the authorized data block size of the mainstream is determined according to the maximum remaining power of the user equipment and the authorized data.

Specifically, assuming that the maximum power corresponding to the authorized data block of the mainstream user equipment is C, the maximum power supported by the authorized transmission block is calculated according to the service authorization value as A; the maximum power supported by the remaining transmission block is determined according to the maximum remaining power as B, then The maximum power corresponding to the mainstream authorized data block is C=MIN{A, B}. Among them, the maximum power supported by the remaining transport blocks is B, which is the total available transmit power of the user equipment minus the power used by the control channel, divide this power by 2 to obtain the maximum available power of the user equipment on a single stream, and then according to the maximum available power Power calculates the maximum power supported by the remaining transport block size supported.

In the same transmission time interval, the grant data includes at least one of scheduling grant data and non-scheduling grant data, and the non-scheduling grant data includes non-scheduling service data and/or scheduling information (Scheduling Information, hereinafter referred to as SI). Assume that the size of the scheduling authorization data to be transmitted is denoted as a, the size of the non-scheduling business data to be transmitted is denoted as b, and the size of the SI to be transmitted is denoted as c. If the authorized data only includes scheduling authorization data, the authorized transmission block size is A =a; if the grant data includes non-scheduling grant data in addition to the scheduling grant data, the grant transmission block size is A=a+b, or A=a+c, or A=a+b+c.

In the above embodiment, if the authorized data also includes non-scheduled data, the authorized maximum block length corresponding to the non-scheduled service data in the non-scheduled data volume can be determined in the following ways:

Use the total length of the non-scheduled data as the size of the non-scheduled authorized transmission block corresponding to the non-scheduled data; or, use half of the total length of the non-scheduled data as the size of the non-scheduled authorized transmission block corresponding to the non-scheduled data; or, according to the main The auxiliary stream power offset parameter and the power corresponding to the amount of non-scheduled data determine the size of the authorized unscheduled transmission block. For example, the power corresponding to the amount of unscheduled data is expressed as P1, and the power offset parameter of the main and auxiliary streams is expressed as S, then according to the formula The calculated result is the power supported by the maximum block length corresponding to the non-scheduled service data. For example, the non-scheduled service data is 10 bits, in the first mode, the block length of the non-scheduled data is 10 bits; in the second mode, the block length of the non-scheduled data is 5 bits; in the third mode , assuming that S is 0.8, the determined non-scheduled data block length is 10*0.8/1.8=4 bits. It can be seen from this that the authorized block lengths corresponding to non-scheduled service data calculated by different methods are also different, and the larger the block length, the greater the power required.

From the above, it can be seen that in the embodiment of the present invention, the size of the mainstream authorized data block cannot exceed the size of the remaining transmission block calculated by the user equipment based on the maximum remaining power, nor can it exceed the size of the authorized data transmission block, that is, the scheduling of the scheduling authorization data The sum of the transport block and the non-scheduled transport block size of the non-scheduled grant data.

In the above example, if the authorized data includes non-scheduled data, preferably, non-scheduled service data is filled in the mainstream, because non-scheduled services are delay-sensitive services that need to be transmitted on high-reliability streams, so it is preferable to re-mainstream transmission. Preferably, the scheduling information SI is filled in the next filled data stream, that is, please refer to Figure 2, when the auxiliary stream is first filled and then the main stream is filled, SI is filled in the main stream; please refer to Figure 3 again, when the main stream is filled first and then the main stream is filled During the auxiliary stream, SI is filled in the auxiliary stream. According to the current technology, the size of the data block used for transmission is a discrete set of transport blocks, and the UE can only select a transport block of a specific size from this set. For example, the available transport blocks in the set are 100 bits, 200 bits, and 300 bits. The data volume of the UE is random, for example, it may be 120 bits, 350 bits, etc. When the UE fills the data according to the authorization, it will select a block that is closest to the data volume allowed by the authorization. For example, if the authorization is 200 bits, the UE data volume is 120 bits. , the UE will select a block length of 200 bits, and the remaining 80 bits can be used to fill scheduling information. Such idle bits will only appear on the last filled data block, therefore, filling the last filled data block with scheduling information can make full use of the idle bits.
