Description

 The present invention relates to the field of wireless communications, and in particular, to a multi-slot bundling transmission method and apparatus, a computer program, and a storage medium. In the current uplink system of Long Term Evolution, in order to enhance the performance of Voice over IP (V lP) or other services, multi-slot bundling (TTI bundling) technology is generally adopted. Continuous time slot (TTI) bundling transmission obtains the reliability of transmission, and solves the problem of improving coverage.

 In order to avoid the design complexity, the collision collision of the transmission, and the transmission delay, in order to avoid the problem of the configuration of the transmission mode when the multi-slot bundling is not performed, the four consecutive time slots are regarded as "" in the prior art. One time slot is processed, and it is considered that a good power accumulation can be obtained after retransmission 3 times, thereby improving performance. Figure 1 shows a schematic diagram of an existing multi-slot bundle transmission. The characteristics of the existing multi-slot bundling technology are as follows:

 Up to 4 consecutive time slots are bundled, that is, 4 ΤΉ bundles.

 2. Perform up to 3 retransmissions, that is, 4 transmissions in total.

 3. The time interval between transmissions is 16ms.

 4. The time to complete 4 transmissions is 52ms.

 Taking the blP service as an example, the solution of multi-slot splicing technology can improve 3⁄41? The uplink coverage of the service, the characteristics of the \3⁄4IP service are:

 The transmission rate is 12,2Kbps.

 2. The interval for sending packets is 20ms, that is, a new packet is sent every 20ms.

 3. Sensitive to delay, requiring a maximum delay of 50ms.

 For small-volume data transmission of VblP services, and delay-sensitive services, multiple TTI bundles are used for transmission, and coverage of the cell edge area can better ensure the transmission time and maximum delay requirements.

However, the inventors found through research that the overall design of the existing TTI bundling has at least insufficient TTIs for effective transmission, and the resource utilization rate is not strong, and the uplink coverage of the 3⁄4 IP service is enhanced. A limited problem.

 For example, as shown in FIG. 2 and FIG. 3, the timing diagram of the existing multi-slot bundling transmission, wherein FIG. 3 is to bundle the four TTIs in FIG. 2 into one particle (ie, the figure in order not to make the graph too long. One of the grids in 3 represents 4 TTIs. It is obvious from the figure:

 (1), as shown in Figure 3, at 3ms in 20ms? Within the packet transmission interval, the number of TTIs that are actually valid for transmission is up to 16 (as shown in the non-blank grid in Figure 3), and at least 20% of the resources are wasted (as shown by the blank grid in Figure 3).

 (2) As shown in Figure 2, for each oIP data packet, 4TTI is bundled and retransmitted 3 times, and the number of 有效 valid for transmission is 16 (as shown in Figure 2, non-blank grid) Show). Since the number of TTIs that are effectively used for transmission is small, in an edge scenario, insufficient power can cause performance loss, and uplink coverage quality is affected.

detailed description

 In order to improve the uplink coverage of the enhanced service, the existing TTI bimdlmg technology is optimized in the embodiment of the present invention. The main idea is to adjust the number of TTIs bundled together and the time interval required for retransmission to achieve the following two objectives:

 (1) Increase the number of TTIs that are effectively used for transmission, improve the power accumulation and the performance gain brought by time diversity, thereby improving coverage.

(2) Improve resource utilization. Taking the schematic diagram of the multi-slot bundling transmission provided by the prior art as shown in FIG. 1 as an example, the number of times slot bindings N is 4, so 4 TTIs transmit data packets together, after the end of the #3 sub-packet transmission After a processing delay of at least 3ms, the ACK/NACK message will be sent in the #7 subframe to indicate whether the data packet is transmitted correctly. If it is NAO, the transmission error will occur, and the system will retransmit until the transmission is correct or the maximum retransmission is reached. frequency. The time interval between transmissions is defined as RTT roimd trip time). In order to meet the requirements of different services, such as the transmission rate or the delay, the time slot bundling length, the RTT transmission time interval, and the maximum number of retransmissions need to be set and optimized. In the embodiments of the present invention, The length of the gap bundle, the RTT time, and the maximum number of retransmissions. The transmission of voice and data into a communication system.

 The solution of the present invention will now be described with reference to the drawings and the embodiments.

 Embodiment 1

 The first embodiment of the present invention provides a multi-slot bundling transmission method. The process of the method may be a network side, such as a base station. The process of the method may be as shown in FIG. 4, and includes:

 Step 101: Determine a time interval RTT and a number of time slots N.

 In this embodiment, in order to increase the number of TTIs that are effectively used for transmission, the existing multi-slot bundling technology uses up to four consecutive time slots for bundling, and the time interval between two transmissions is 16 ms, for multi-slots. Bundle technology to improve.

 Specifically, the time interval RTT of the two transmissions in the multi-slot bundling and the number N of the bundled time slots may be determined, where the RTT is a positive number, and the N is a positive integer. Wherein, the determined RTT is no more than 16 milliseconds, and/or, the determined N is not less than 4. And, if the determined RTT is 16 milliseconds, the determined N is greater than 4; if the determined N is 4, the determined RTT is not equal to 16 milliseconds.

 Therefore, by reducing the time interval RTT of the two transmissions, and/or increasing the number of bundled slots, the number of TTIs that are effectively used for transmission is increased, resource utilization is improved, and performance loss caused by insufficient power in the edge scenario can be reduced. The problem, thus enhancing the uplink coverage.

 Step 102: Determine the number of retransmissions.

 Further, on the basis of adjusting the time interval RTT of the two transmissions in the multi-slot bundling and the number N of bundled slots, the number of TTIs that are effectively used for transmission is increased, and resource utilization is improved, thereby enhancing uplink coverage. It is also possible to adjust the number of retransmissions to further increase the number of TTIs that are effectively used for transmission, thereby improving resource utilization.

 For the existing multi-slot congestion technology, a maximum of three retransmissions are performed, that is, a total of four transmissions are performed. The number of retransmissions determined in this embodiment may be greater than three, and may not be greater than three.

For step 101 to step 102, the interval RTT, the number of slots N, and the number of retransmissions may be determined by any one of the following three methods: Manner 1: The number of time slots used for transmission within the maximum delay of the ffi service determines the number of RTT, N, and retransmissions.

 In this manner, the maximum delay required by the service may be determined, and the time interval of the two transmissions in the multi-slot bundling is determined according to the number of time slots used for transmission in the maximum delay is not lower than the first set value, The number of retransmissions and the number of timeslots bundled.

 For example, for the VoIP service, the number of time slots for transmission in the multi-slot bundle, the number of times of retransmission, and the time of bundling can be determined according to the maximum delay of 50 ms required by the VoIP service. The number of gaps.

 According to the method, the time interval RTT. of the two transmissions, the number of bundled slots N, and the number of retransmissions can be determined, so that the number of H slots used for transmission within the maximum delay required by the service meets the requirements, thereby achieving Increase the number of valid FFIs in the transmission of TTIs, improve resource utilization, and enhance the purpose of uplink coverage.

 Manner 2: Determine the number of RTTs, Ns, and retransmissions by using the number of time slots used for transmission during the transmission interval of the service.

 In this manner, it may be determined that the transmission interval H between the service requirements is determined, and the time of two transmissions in the multi-slot bundling is determined according to the number of time slots used for transmission in the transmission interval is not lower than the second set value. Interval, number of retransmissions, and number of bundled slots. Specifically, the time interval, the number of retransmissions, and the bundled time slots of the two transmissions in the multi-slot bundling may be determined according to the maximum number of time slots used for transmission in the transmission interval is not lower than the second set value. number.

 For example, for the VoIP service, the maximum number of time slots for transmission in the 20 ms transmission interval required by the VoIP service is not less than 16, and the time interval, number of retransmissions, and bundling of the two transmissions in the multi-slot bundling are determined. The number of time slots.

The time interval RTT of the two transmissions determined according to this manner, the number of bundled slots N, and the number of retransmissions can make the required number of transmission slots meet the requirements in the required transmission interval, thereby increasing the number of transmissions. The number of TTIs used for transmission improves resource utilization and enhances uplink coverage. Method 3: Determine the TT, N and the number of retransmissions by using the difference between the maximum delay of transmission and the maximum delay required by the service.

 In this manner, the maximum delay required by the service may be determined, and the time interval RTT of the two transmissions in the multi-slot shackle is determined according to the difference between the maximum delay of the transmission and the maximum delay required by the service. The number N of bundled time slots and the number of retransmissions are determined, wherein the maximum transmission delay indicates the length of time taken during the last transmission of the execution.

 Specifically, the maximum transmission delay may be expressed as the sum of the number N of bundled times and the product of the number of retransmissions and the time interval RTT of two transmissions.

 For example, for VoIP services, can be based on 3⁄41? The maximum delay required by the service is 50ms, and the difference between the maximum delay of transmission and the maximum delay required by the IP service is 10ms. Determine the interval of two transmissions in the multi-slot bundle, the number of retransmissions, and the bundled The number of time slots.

 According to this method, the time interval, the number of retransmissions, and the number of bundled times in the multi-slot bundling are determined, and the maximum delay of the transmission can be ensured to meet the set requirements, thereby ensuring that an increase in effective transmission is achieved. Number, improve resource utilization, and enhance the purpose of uplink coverage.

 In this embodiment, the time interval RTT of the two transmissions in the multi-slot bundling, the number N of bundled slots, and the retransmission may be determined by using, but not limited to, the maximum delay required by the service and the transmission interval of the Z or the required transmission interval. The number of times, and other methods, such as determining the interval RTT of two transmissions in the multi-slot bundle, the number of slots N to be bundled, and the number of retransmissions may be determined according to other service parameters.

The execution body of step 101 and step 102 in this embodiment may be the network side. After the network side determines the time interval TT., the number of slots N, and the number of retransmissions, the determined time interval RTT, time may also be determined. The number of slots N and the number of retransmissions are transmitted to the terminal, and the terminal is instructed to perform uplink transmission according to the interval RTT, the number of slots N, and the number of retransmissions. Specifically, the network side may transmit the determined time interval RTT., the number of slots N, and the number of retransmissions to the terminal by using specified signaling. And during transmission, the network side may transmit the determined interval RTT, the number of slots N, and the number of retransmissions to the terminal according to a manner agreed in advance with the terminal. Then, the terminal can parse out the time interval RTT, the number of slots N, and the number of retransmissions according to a predetermined manner, and analyze the time interval RTT and time slot. The number N and the number of retransmissions are uplinked.

 The solution of the first embodiment of the present invention will be described below by way of specific examples.

 Embodiment 2

Assume that for voice or data traffic, it is obtained according to the determined RTT, N and retransmission times.

 For the VoIP service, the RTT is determined to be 12 milliseconds, the number of retransmissions is 4, and N is 4 (schema 1). The timing diagram of multi-slot bundling transmission can be as shown in FIG. 5.

 For the VoIP service, the determined RTT is 15 milliseconds, the number of retransmissions is 3, and N is 5 (schema 2). The timing diagram of multi-slot congestion transmission can be as shown in Figure 6.

 For the 3⁄4IP service, the RTT is determined to be 14 milliseconds, the number of retransmissions is 2, and N is 6 (scheme 3). The timing diagram of multi-slot bundling transmission can be as shown in Figure 7.

 For the VoIP service, the determined TT is 30 milliseconds, the number of retransmissions is 1 time, and N is 10 (scenario 4). For example, the timing diagram of multi-slot congestion transmission can be as shown in Figure 8.

 Referring to the timing diagrams shown in FIG. 5, FIG. 6, FIG. 7, and FIG. 8, if the RTT of the existing scheme is 16 milliseconds, the number of retransmissions is 3, and N is 4, a scheme comparison as shown in Table i can be obtained. Result:

 Table 1

The maximum number of transmissions is the number of retransmissions plus one, and the maximum transmission delay indicates the length of time occupied by the last transmission after the completion of the execution (can be expressed as the number of bundled slots N, and the number of retransmissions and two transmissions) The sum of the products of the time interval RTT is used to transmit the number of TTIs expressed in the VoIP requirements. The number of time slots used for transmission within the maximum delay. The resource utilization rate represents the maximum number of time slots used for transmission in the 20 ms transmission interval required by the IP service, and the ratio of the transmission interval time.

 As can be seen from Figure 5, Figure 6, Figure 7, Figure 8, and Table 1, Scheme 1, Scheme 2, Scheme 3, and Scheme 4 reduce the number of TTI bundlings and/or change the number of retransmissions by reducing RTT and/or Thereby increasing the number of TTIs for transmission. Under the requirement of maximum delay, for the existing scheme, the effective number of schemes 1 increases from 16 to 20, the effective number of schemes 2 increases from 16 to 20, and the effective number of scheme 3 increases from 16 to 18. The effective number of four increases from 16 to 20, increasing power accumulation and time diversity gain. Moreover, resource utilization has also increased by 20%, 20%, 10% and 20%, respectively.
