Description

Data transmission method and related equipment

Technical field

The present application relates to the field of communications, and in particular, to a data transmission method and related devices.

Background technique

Machine Type Communication (MTC) refers to the acquisition of information about the physical world by deploying various devices with certain sensing, computing, execution, and communication capabilities, and realizes information transmission, coordination, and processing through the network. The interconnection of things, things and things. For the MTC, the uplink data of the user equipment (User Equipment, UE) is carried by a Physical Uplink Shared Channel (PUSCH). The base station performs scheduling on the PUSCH by using Downlink Control Information (DCI), that is, information indicating resource allocation and modulation and coding mode of the PUSCH.

In the MTC, the base station can configure the PUSCH to perform frequency hopping. That is, when the UE sends uplink data in multiple subframes, the frequency resources of the uplink data sent by the multiple subframes are hopped, and the uplink data corresponds to one transport block. The hopping interval of the base station configurable PUSCH hopping is

That is, the frequency resource that the UE sends the uplink data.

The subframes are hopped once, that is, before the frequency resource hopping of the uplink data by the UE, the number of consecutive absolute subframes in which the frequency resource of the uplink data that the UE sends the uplink data remains unchanged is

The subframe in which the frequency resource of the uplink data is hopped by the UE in multiple subframes is based on

The calculation with the absolute subframe number has nothing to do with the starting subframe for transmitting the uplink data. When the UEs having the same hopping interval respectively transmit uplink data corresponding to one of the transport blocks in a plurality of subframes, the UE transmits the uplink data at the same subframe position. As shown in FIG. 1, UE1 and UE2 respectively transmit uplink data corresponding to a respective one of the transport blocks in eight subframes, and the frequency hopping interval is respectively performed.

For example, the starting subframes in which the uplink data is sent by UE1 and UE2 are different, but the frequency resources in which the uplink data is transmitted by UE1 and UE2 are hopped in the subframes in which the absolute subframe numbers are 2, 4, and 6.

In order to improve the uplink spectrum efficiency of the MTC, one of the effective technical means is to allocate the frequency resource for transmitting the uplink data by the UE in units of subcarriers, and the frequency resource for transmitting the uplink data by the UE includes less than 12 subcarriers. In the existing Narrow Band Internet of Things (NB-IoT), the frequency resources of the uplink data transmitted by the UE are allocated in units of subcarriers, so that the manner of transmitting the uplink data in the NB-IoT can be learned. MTC. In NB-IoT, when transmitting uplink data corresponding to a transport block, the UE performs channel coding, rate matching, and the like on a transport block to obtain a codeword, scramble, modulate, and layer map the one codeword. The uplink data is obtained after transform precoding and precoding, and the uplink data is mapped to one or more resource units (RUs), and the number of resource units to be mapped is _NRU . The number of subcarriers that a RU contains on the frequency

Less than or equal to 12, the number of time slots included in time

Greater than or equal to 2. The UE performs N _Rep repeated transmission on the uplink data mapped to each RU, and the N _Rep is indicated by the downlink control information. The number of time slots occupied by uplink data transmission corresponding to one transport block is

One. When the subcarrier spacing is 15 kHz, when the uplink data after precoding corresponding to one transport block is mapped, after mapping to two time slots, the uplink data mapped to the two time slots is additionally transmitted repeatedly.

Times, get in

The uplink data repeatedly transmitted in the time slots, and the uplink data after the precoding corresponding to the transport block continues to be mapped to the uplink data.

Two slots after the time slot are transmitted until a cell is mapped to _NRU resource units to complete a cyc le transmission. The uplink data corresponding to the transport block continues to be sent in the next cycle until the number of occupied slots is

One. The uplink data uses a redundancy version (RV) when performing rate matching on each cycle, and the redundancy version adopted in two consecutive cycles is different. among them,

In NB-IoT,

The value is 1, 2 or 4. Figure 2 shows the transmission of uplink data in NB-IoT. In FIG. 2, the number of resource units to which the uplink data corresponding to one transport block is mapped is _NRU =4, and the four RUs are respectively recorded as 0, 1, 2, and 3, and one RU includes two slots. N _Rep = 4, the transmission of the uplink data occupies 32 time slots.

Equal to 2, one cycle contains 16 time slots. RV0 is used in cycle 0 and RV2 is used in Cycle 1.

When the MTC adopts a transmission method similar to the uplink data in the existing NB-IoT,

Recorded as

Frequency resource of uplink data

The sub-frames jump once. when

When the frequency resource of the uplink data is hopped, the subframe may be repeatedly sent by the uplink data.

Among the subframes in which the slots are located, the subframes after the first subframe. For example, in Figure 3,

The uplink data transmission starts from the subframe with the absolute subframe number of 1, and is calculated according to the manner in which the subframe in the MTC is hopped for the frequency resource of the uplink data, and the subframe 2 with the absolute subframe number of 2 (or the subframe) 4, 6, 8, 10, 12, 14, 16), the UE repeatedly transmits the uplink data sent in the previous subframe, and the frequency resource that sends the uplink data changes. Since the channel condition experienced by transmitting the uplink data on the frequency resource after the hopping has a large difference between the channel condition experienced by transmitting the uplink data on the frequency resource before the hopping, so that the base station receives the uplink data, Can't be right

The uplink data of the repeated transmission of the time slots is symbol-level merged, thereby increasing the processing complexity of the base station. The symbol level combining means that the base station performs superposition processing on the received uplink data before channel equalization. Similarly, when

When the frequency resource for transmitting uplink data remains unchanged

The uplink data of one subframe may not be sent repeatedly, that is, it may appear

The uplink data after precoding performed by the subframes is different, and/or the RV of the transmitted uplink data is different, so that the base station cannot receive the uplink data when it receives the uplink data.

The uplink data sent by the subframes is symbol-level merged, thereby increasing the processing complexity of the base station.

Summary of the invention

The embodiment of the present invention provides a data transmission method and related device, which can solve the problem that the base station cannot perform symbol level merging on the uplink data when receiving uplink data, so that the processing complexity of the base station is high.

In a first aspect, a data transmission method is provided, which is applied to a communication device, and the communication device sends uplink data to a network device, where the uplink data corresponds to one transport block, wherein the communication device maps the first part of the uplink data to two time slots, The first part is additionally repeated M-1 times to obtain data to be transmitted on the first 2*M time slots, and M is a positive integer greater than 1; the communication device then maps the second part of the uplink data to the first 2 * Two time slots after M time slots, the second part is additionally repeated M-1 times to obtain data to be transmitted on the second 2*M time slots after the first 2*M time slots, communication The apparatus transmits data to be transmitted on the first 2*M time slots on the time slot in the first 2*M time slots and on the first frequency resource, and in the second 2*M time slots Transmitting data to be transmitted on the second 2*M time slots on the slot and the second frequency resource; or, the communication device is on the time slot in the first M time slots of the first 2*M time slots and Transmitting, on a frequency resource, data to be transmitted on the first 2*M time slots, on the time slot in the last M time slots, and on the second frequency The data to be transmitted on the first 2*M time slots is transmitted on the resource, wherein the first frequency resource may be different from the second frequency resource. In this way, since the data transmitted on the time slots in the 2*M time slots is the same, that is, the data of the first part or the data of the second part, the frequency resources are also the same, and the base station can be in the time of 2*M time slots. The uplink data sent on the slot and the same frequency resource are symbol-level merged, which reduces the processing complexity of the base station, or the same frequency resource is transmitted because the data transmitted by the first M time slots of 2*M time slots is the same. The data transmitted by the last M time slots is the same, and the frequency resources are also the same. The base station can perform symbol level merging on the uplink data sent on the first frequency resource in the first M time slots of 2*M time slots, and can The uplink data transmitted by the time slots in the M time slots on the second frequency resource is symbol-level merged.

Therefore, since N is greater than or equal to M, frequency resources of uplink data transmitted on time slots in 2*M time slots are the same, and data to be transmitted on 2*M time slots is a repetition of the first part of uplink data or The repetition of the second part of the uplink data allows the base station to perform symbol level combining. Alternatively, if the number of consecutive subframes N in which the frequency resource of the uplink data remains unchanged by the communication device is less than M, and N is a positive integer greater than 1, the communication device is in the first M time slots of 2*M time slots. The data to be transmitted on the first 2*M time slots on the slot and the first frequency resource transmitting part, the time slot in the last M time slots and the second frequency resource transmitting part in the first 2*M time slots The data to be sent. Therefore, since N is smaller than M, the frequency resources of the time slots in the first M time slots are the same, and the data transmitted in the time slots in the first M time slots is the repetition of the first part of the uplink data, and the last M time slots. The frequency resources of the time slots in the same are the same, and the data transmitted in the time slots in the last M time slots is a repetition of the first part of the uplink data, which may facilitate the base station to transmit the part of the time slots in the first M time slots.

Time slot: One subframe includes two time slots.

Physical Resource Block (PRB): contains one time slot in time, and contains 12 subcarriers in frequency when the subcarrier spacing is 15 kHz.

Uplink data hopping transmission: The UE transmits uplink data in multiple subframes, and the frequency resource in which the uplink data is transmitted in multiple subframes is hopped. That is, in the first subframe and the second subframe of the multiple subframes, the frequency resources of the uplink data sent by the UE are different. The uplink data corresponds to one transport block.

Frequency hopping interval: The number of consecutive absolute subframes in which the frequency resource in which the uplink data is transmitted by the UE remains unchanged.

for

The subframe number is n _s , which is the number of the subframe included in one radio frame, and n _s is an integer whose value is 0-9. n _f is the number of the radio frame, and the value is an integer from 0 to 1023.

Resource Un it (RU): the number of subcarriers that a RU contains on the frequency.

Less than or equal to 12, the number of time slots included in time

The basic principles of the embodiments of the present application are described below.

The base station sends downlink control information to the UE, where the downlink control information is used to schedule a physical uplink shared channel, that is, the downlink control information indicates information such as resource allocation and modulation and coding mode of the physical uplink shared channel. For example, the physical uplink shared channel may be a PUSCH. The UE further performs channel coding, rate matching, and the like according to the indication of the base station to obtain a codeword, and performs scrambling, modulation, layer mapping, transform precoding, and precoding on the codeword to obtain the transport block. Corresponding uplink data, the uplink data is mapped to the physical resource, and the uplink data corresponding to the transport block is sent in one or more subframes, that is, the uplink data is sent to the base station on the physical uplink shared channel. The base station may configure the UE to perform frequency hopping to send uplink data, that is, when the UE sends uplink data corresponding to one transport block to the base station in multiple subframes, the frequency of the uplink data is sent in the first subframe and the second subframe of the multiple subframes. Different resources. It should be noted that, the manner in which the UE performs the processing of the one to be sent according to the indication of the base station, and the method for obtaining the uplink data corresponding to the transport block includes, but is not limited to, the foregoing manner, which is not limited in this application.

When the UE maps the uplink data corresponding to one transport block to the physical resource, the UE may map the uplink data to the two time slots and repeat the M-1 times of the uplink data mapped on the two time slots. Obtaining uplink data to be transmitted on 2*M time slots, and then mapping part of the uplink data to two time slots after 2*M time slots until mapping the uplink data to _NRU resource units RU. When the uplink data is co-mapped to N _RU resource units consisting of several two time slots, one cycle is completed, and then the uplink data is further mapped to N _RU resource units in the next cycle until mapping to each RU. The uplink data is repeated for N _Rep times. M can also be understood as the number of times that uplink data mapped to one RU in a loop is repeated (including uplink data and repeated uplink data mapped to one RU). In each cycle, the rate matching process uses a redundancy version (RV), and the redundancy versions used in two consecutive cycles are different. In the embodiment of the present application, the repetition of the uplink data refers to the fact that the uplink data after the precoding to be transmitted is the same in every two slots of the multiple slots or each subframe of the multiple subframes.

It should be noted that, in the embodiment of the present application, M and

The meaning is the same, N and

The meaning of the representation is the same, and the uplink data refers to the uplink data corresponding to one transport block. FIG. 2 is a schematic diagram of mapping, by the UE, uplink data corresponding to one transport block to physical resources. In FIG. 2, the number of resource units to which the uplink data corresponding to one transport block is mapped is _NRU =4, and the four RUs are respectively recorded as 0, 1, 2, and 3, and one RU includes two slots. N _Rep = 4, the uplink data is mapped to 32 time slots.

In order to solve the MTC, the present application adopts a transmission method similar to the uplink data in the existing NB-IoT, and the frequency resource of the uplink data.

Subframes change once,

Greater than 1 and

If the value is greater than 1, it is not suitable for the base station to perform symbol level combining on the uplink data when receiving the uplink data, thereby increasing the processing complexity of the base station. The application needs to achieve the following purposes:

After the UE maps the first part of the uplink data to two time slots, the first part is additionally repeated M-1 times to obtain data to be transmitted on the first 2*M time slots, where M is a positive integer greater than 1; On this basis, the UE needs to do the following when sending the uplink data: 1) The UE then maps the second part of the uplink data to the two slots after the first 2*M slots, and the second part additionally repeats M-1. And obtaining data to be transmitted on the second 2*M time slots after the first 2*M time slots, where the UE is on the time slot in the first 2*M time slots and on the first frequency resource Transmitting data to be transmitted on the first 2*M time slots, and transmitting on the second 2*M time slots and on the second frequency resource to be transmitted on the second 2*M time slots The data;

Or, 2) the UE sends the data to be sent on the first 2*M time slots on the time slots in the first M time slots of the first 2*M time slots and on the first frequency resource, and then The data to be transmitted on the first 2*M time slots on the time slots in the M time slots and the second frequency resource transmission part.

These two cases can be determined according to the size relationship between M and N.

When N≥M, that is, the hopping interval is greater than or equal to the number of times the uplink data mapped to one RU is repeated in one cycle, at which time, the UE may be in the time slot or the second in the first 2*M time slots. Uplink data is transmitted on the time slots in the 2*M time slots and on the same frequency resource, that is, the UE may send the first 2* on the time slots in the first 2*M time slots and on the first frequency resource. The data to be transmitted on the M time slots transmits the data to be transmitted on the second 2*M time slots on the time slots in the second 2*M time slots and on the second frequency resource. That is, the frequency resource of the uplink data does not jump in a subframe other than the first subframe in the subframe where the first 2*M slots or the second 2*M slots are located. . Thus, when M>1, when receiving the uplink data, the base station may repeatedly send the uplink data to the time slot in the first 2*M time slots or the time slot in the second 2*M time slots. Perform symbol level merging to reduce the processing complexity of the base station.

Or, when M>N, that is, the uplink data mapped to one RU in one cycle is repeated more than the hopping interval, and when N>1, the subframe in which the frequency resource that sends the uplink data hops is first. Between the 2*M time slots or the second 2*M time slots, in order to enable the base station to perform symbol level combining on the uplink data, the first 2*M time slots are taken as an example, and the first 2* may be used. M The uplink data in which the time slots in the first M time slots of the time slot are repeatedly transmitted are symbol-level merged, and the uplink in the last M time slots of the first 2*M time slots is repeatedly transmitted. The data is subjected to symbol level merging, and the UE may send the part in the first frequency slot on the time slot of the first M time slots of the first 2*M time slots and the first frequency resource in the first 2 when transmitting the uplink data. * Data to be transmitted on M time slots, on the time slots in the last M time slots and on the second frequency resource, the data to be transmitted on the first 2*M time slots is transmitted. Similarly, the UE may further map the second part of the uplink data to two time slots after the first 2*M time slots, and the second part is additionally repeated M-1 times to obtain the first 2*M. Data to be transmitted on the second 2*M time slots after the time slot, and the UE transmits the part on the time slot in the first M time slots of the second 2*M time slots and on the first frequency resource. The data to be transmitted on the second 2*M time slots, the time slots on the last M time slots and the data to be transmitted on the second 2*M time slots are transmitted on the second frequency resource. The first frequency resource and the second frequency resource may be different. That is, the frequency resource of the time slot uplink data transmission in the first M time slots remains unchanged, and the frequency resource of the time slot uplink data transmission in the last M time slots remains unchanged, so that the base station can perform the uplink data repeatedly transmitted. Symbol level merging reduces the processing complexity of the base station.

It should be noted that, taking the first 2*M time slots as an example, the first 2*M time slots may be consecutive time slots or may be discontinuous time slots. The first 2*M time slots may include only the time slot in which the effective uplink subframe is located, and may include both the time slot in which the effective uplink subframe is located and the time slot in which the invalid uplink subframe is located. The time slots in the first 2*M time slots (or the time slots in the first M time slots, or the time slots in the last M time slots) may be the first 2*M time slots (or All of the first M time slots, or the last M time slots, may also be partial time slots.

In one mode, when the first 2*M time slots only include the time slot in which the effective uplink subframe is located, the time slots in the first 2*M time slots (or the time in the first M time slots) The slot, or the slot in the last M slots) is all of the 2*M slots (or the first M slots, or the last M slots). At this time, there may be an invalid uplink subframe between the first 2*M time slots, that is, the first 2* time slots may be discontinuous time slots.

In another mode, the first 2*M time slots include the time slot in which the effective uplink subframe is located, and the time slot in which the invalid uplink subframe is located, in the first 2*M time slots. The time slot (or the time slot in the first M time slots, or the time slot in the last M time slots) is the first 2*M time slots (or the first M time slots, or the last M time slots) The time slot in which the effective uplink subframe is located, that is, the partial time slot. At this time, the first 2* time slots are consecutive time slots.

In the embodiment of the present application, the starting subframe of the uplink data mapping is the starting subframe of the first RU in the RU of the uplink data mapping.

In a possible manner, when N≥M, if M is a divisor of N, when M>1, when the base station receives the uplink data, the base station may keep N subframes unchanged for the frequency resource of the uplink data. It is divided into N/M sets consisting of M subframes, and the uplink data transmitted on M subframes in each set is symbol-level merged.

Or, in another possible manner, when M>N, if N is a divisor of M, and N>1, when the base station receives the uplink data, the base station may maintain the same frequency resource in the uplink data. A portion of the uplink data transmitted by the N subframes is symbol-level merged.

In one possible manner, M=min(4, N _Rep /2), min represents a minimum value operation, and N _Rep represents a repetition number of the uplink data transmission indicated by the downlink control information.

Illustratively, the above M may be equal to 2 or 4, etc., and the above N may be equal to one of 2, 4, 8, 16. The embodiment of the present application can also be applied to the case of N=1 or M=1.

The following implementation manners of the embodiments of the present application are exemplified to achieve the above objectives. The following first possible implementation to the fourth possible implementation may be applied to the FDD system.

In a first possible implementation, the UE receives the end subframe of the downlink control information sent by the base station as the subframe n, the sub The fourth subframe after the frame n is the subframe n+4, and the starting subframe of the uplink data corresponding to the UE transmitting one transport block is the subframe n+4 and the first absolute subframe number of the subsequent subframe is i Valid uplink subframe, and i satisfies the condition: i mod X=0, X=min(M,N); where n, i are integers greater than or equal to zero. Mod represents the modulo operation or the remainder operation, and min represents the minimum value operation.

The starting subframe of the uplink data mapping is a subframe with an absolute subframe number i.

For the steps that the base station and the UE can perform, the following steps can be included:

111. The base station sends downlink control information to the UE. The end subframe of the downlink control information is subframe n, and the fourth subframe after the subframe n is subframe n+4.

112. The UE receives the downlink control information sent by the base station.

113. The UE sends the uplink data corresponding to the transport block to the base station, where the initial subframe for transmitting the uplink data is a valid uplink subframe with the first absolute subframe number i in the subframe n+4 and the subsequent subframe. And i satisfies the condition: i mod X=0, X=min(M,N). Information such as a modulation and coding scheme and a frequency resource used in the uplink data is indicated by the downlink control information.

114. The base station receives the uplink data sent by the UE.

In all uplink subframes, there may be an invalid uplink subframe, and all subframes except the invalid uplink subframe may be valid uplink subframes in all uplink subframes. Of course, there may be no invalid uplink subframes, that is, all uplink subframes are valid uplink subframes. The valid uplink subframe may be configured by the base station to the UE by using system information, and may be an uplink subframe of the BL UE or the CE UE. The BL UE and the CE UE are UEs capable of supporting MTC services.

In the prior art, the starting subframe for the uplink data transmission corresponding to one transport block is the first valid uplink subframe in the subframe n+4 and the subsequent subframe, but the base station may not be able to perform the uplink data. The problem of symbol level merging, and in the embodiment of the present application, the absolute subframe number i of the starting subframe of the uplink data transmission needs to satisfy the condition: i mod X=0, X=min(M,N), so that And causing the UE to send part of the uplink data on a time slot in the first 2*M time slots or a time slot in the second 2*M time slots, or send the same on the same frequency resource, or make the UE The frequency resources of the uplink data are transmitted on the time slots of the first M* timeslots or the first M time slots of the second 2*M time slots, and the transmission parts of the time slots in the last M time slots are transmitted. The frequency data of the uplink data is the same.

The following three examples assume that all subframes are valid uplink subframes.

In one example, as shown in FIG. 7, one possible way of uplink data hopping transmission, in the example of FIG. 7, when N=2, and M=2, the prior art and the present application adopt the above first In a possible implementation, the uplink data hopping is compared when sent. As shown in FIG. 7, the base station transmits the downlink control information MPDCCH, that is, the subframe n is the subframe 1, and the uplink data corresponding to the transport block is mapped to the four RUs, and the uplink data of each of the RUs is performed. The secondary transmission is repeated, and one RU occupies two time slots. In the prior art, the initial subframe for transmitting the uplink data is the first valid uplink subframe in the subframe n+4 and the subsequent subframe, that is, the subframe 5, A part of the uplink data sent on the subframe 5 is the data mapped to the first RU, and the uplink data sent by the subframe 6 is repeated for the data on the first RU, but the subframe 6 is obtained. A frequency hopping occurs, and frequency hopping occurs in subsequent subframe 8, subframe 10, and subframe 12, and the base station cannot perform symbol level merging on the uplink data. However, when the first possible implementation manner of the present application is adopted, X=min(2, 2)=2, the effective uplink subframe of the first absolute subframe number i in the subframe after subframe 5 and subframe 5 is i. The subframe that satisfies i mod 2=0 is the subframe 6, and the subframe 6 is the starting subframe in which the uplink data corresponding to the transport block starts to be transmitted, and is also the starting subframe of the uplink data mapping corresponding to the transport block. Thus, a portion of the uplink data transmitted on the subframe 7 is obtained by repeating the data mapped to the first RU by the uplink data, and no frequency hopping occurs at the subframe 7. When the first possible implementation manner of the present application is used, the time slot UEs in 2*M, that is, 4 time slots, can transmit part of the uplink data in the same frequency resource, and then the base station can access the 4 time slots. For example, the uplink data transmitted on the subframe 6 and the subframe 7 is symbol-level merged.

In an example, as shown in FIG. 8 is another possible way of uplink data hopping transmission. In the example of FIG. 8, when N=4, and M=2, the prior art and the present application adopt the above-mentioned In a possible implementation, the uplink data hopping is compared when sent. As shown in FIG. 8, the base station transmits the downlink control information MPDCCH, that is, the subframe n is the subframe 1, and the uplink data corresponding to the transport block is mapped to the four RUs, and the uplink data of each of the RUs is performed. The secondary transmission is repeated, and one RU occupies two time slots. In the prior art, the initial subframe for transmitting the uplink data is the first valid uplink subframe in the subframe n+4 and the subsequent subframe, that is, the subframe 5, The data sent on the subframe 5 is mapped to the data on the first RU. The data on the first RU is repeatedly sent once on the subframe 6. The subframe 7 is sent to the uplink data. The data on the two RUs, the data on the second RU is repeatedly transmitted once on the subframe 8, but the frequency hopping occurs at the subframe 8, and the base station cannot transmit the uplink to the portion transmitted on the subframe 7 and the subframe 8. The data is symbolically merged. However, when the first possible implementation manner is adopted in the foregoing application, the initial subframe for sending the uplink data is the subframe 6, and although the frequency hopping occurs at the subframe 8, the subframe 6 and the subframe 7 occupy the frame. The frequency resources of the 2*M time slots, that is, the time slots of the 4 time slots are the same, the frequency resources of the 4 time slots occupied by the subframe 8 and the subframe 9 are the same, and so on, so that the UE can be 2*M. The time slot in the time slot transmits part of the uplink data in the same frequency resource, and the base station performs symbol level combining on the uplink data repeatedly transmitted in different subframes, for example, performing part of the uplink data sent on the subframe 6 and the subframe 7. The symbol level is combined, and the uplink data transmitted on the subframe 8 and the subframe 9 is symbol-level merged.

In an example, as shown in FIG. 9, another possible manner of uplink data hopping transmission, in the example of FIG. 9, when N=2, and M=4, the prior art and the present application adopt the above-mentioned In a possible implementation, the uplink data hopping is compared when sent. It can be seen from FIG. 9 that the end subframe in which the base station transmits the downlink control information MPDCCH, that is, the subframe n is the subframe 1, and the uplink data corresponding to the transport block is mapped to the two RUs, and the uplink data of each of the RUs is performed. The secondary transmission is repeated, and one RU occupies two time slots. In the prior art, the initial subframe for transmitting the uplink data is the first valid uplink subframe in the subframe n+4 and the subsequent subframe, that is, the subframe 5, The data transmitted on the subframe 5 is mapped to the data on the first RU, and the data on the first RU is repeatedly transmitted on the subframe 6, and the frequency hopping occurs in the subframe 6, the subframe 8, the sub-frame The frequency hopping also occurs at the frame 10. After the data mapped on the first RU is repeated 4 times in the first cycle, the data sent on the subframe 9 is mapped to the data on the second RU. The frequency resources of the uplink data transmitted on the frame 7 and the subframe 8 are different, and the base station 8 and the subframe 9 transmit different portions of the uplink data, and the base station cannot perform symbol level combining. Compared with the first possible implementation manner of the present application, the starting subframe of the uplink data transmission is subframe 6, the data transmitted in the subframe 6 is repeated on the subframe 7, and the subframe 6 and the subframe 7 are sent. The frequency resources of the uplink data are the same. Although the frequency hopping occurs at the subframe 8, the frequency resources of the uplink data sent by the subframe 8 and the subframe 9 are the same, that is, when the UE is at 2*M. The slot, that is, the slot in the first 4 slots of the 8 slots, the part of the uplink data has the same frequency resource, and the slot in the last 4 slots transmits the same spectrum resource of the uplink data, and the base station can The uplink data is subjected to symbol level combining, for example, performing symbol level combining on a part of the uplink data sent on the subframe 6 and the subframe 7, and performing symbol level combining on the uplink data sent on the subframe 8 and the subframe 9.

Of course, the first possible implementation manner of the foregoing application may also be applicable to the case where there is an invalid uplink subframe. As shown in FIG. 10, when N=2, and M=2, another schematic diagram of a frequency hopping transmission mode of uplink data in the prior art and the first possible implementation manner of the present application. In FIG. 10, the subframes whose absolute subframe numbers are 6 and 16 are invalid uplink subframes. If the first possible implementation manner is adopted, the initial subframe of the uplink data transmission is a subframe with an absolute subframe number of 5 and a first uplink subframe of the subsequent subframe that satisfies i mod 2=0. , that is, a subframe with an absolute subframe number of 8. In the prior art, when the transmission of the uplink data encounters an invalid uplink subframe, the transmission of the uplink data is deferred to the effective uplink subframe after the invalid subframe. In FIG. 8, in the prior art, the uplink data is transmitted on the subframe 5 to the data on the first RU, and the subframe 6 is an invalid subframe, and the subframe 7 is repeatedly sent to the first RU. Data, the frequency hopping occurs at the subframe 7, and the base station cannot perform symbol level merging on the uplink data of the part of the subframe 5 and the subframe 7 repeatedly transmitted. Similarly, the subframe 16 is an invalid uplink subframe, and the uplink data mapping To the second RU The data is deferred to be transmitted on the subframe 17, and the data on the second RU is repeatedly transmitted on the subframe 18, but the frequency hopping occurs at the subframe 18, and the base station cannot transmit the portion transmitted on the subframe 17 and the subframe 18. The uplink data is symbol-level merged, and part of the uplink data sent on the subframe 19 and subsequent subframes cannot be symbol-level merged. If the first possible implementation manner is used, the initial subframe of the uplink data transmission is the subframe 8, and the data of the uplink data mapped to the first RU is transmitted on the subframe 8 and the subframe 9, and the subframe 10 is received. And transmitting the uplink data on the subframe 11 to the data on the second RU, and transmitting the same portion of the uplink data in the four slots of the subframe 8 and the subframe 9, and the frequency resources are also the same, and the subframe 10 and the subframe 11 are the same. The same part of the uplink data is transmitted on the four time slots, and the frequency resources are also the same. The uplink data to be transmitted on the invalid uplink subframe 16 is discarded, and the part of the uplink data transmitted on the subframe 17 cannot be symbol-level merged. The rest of the upstream data corresponding to the transport block can be symbol level merged. For example, the base station may perform symbol level combining on a portion of the uplink data sent on the subframe 8 and the subframe 9, and perform symbol level combining on the portion of the uplink data sent on the subframe 10 and the subframe 11.

Therefore, the embodiment of the present application may be applicable to: uplink data to be sent in consecutive R subframes starting from a start subframe of the uplink data mapping, and if the uplink data is sent by the UE, if there are invalid uplinks in consecutive R subframes In the subframe, the UE discards part of the uplink data to be sent on the invalid uplink subframe, where R is an integer greater than 1. In other words, if the sequence starts from the start subframe of the uplink data map corresponding to one transport block

If there is an invalid uplink subframe in the subframe, the uplink data to be transmitted in the invalid uplink subframe will be discarded. N _Rep indicates the number of times the uplink data is repeatedly transmitted on each RU, and N _RU indicates the number of uplink data of one transport block mapped to the number of RUs.

The starting subframe of the corresponding uplink data is the subframe with the absolute subframe number i and the first valid uplink subframe in the subsequent subframe, and the subframe with the absolute subframe number i is the subframe n+4. And the first one of the subsequent subframes satisfies the condition: i mod X=0, X=min(M,N); wherein n, i are integers greater than or equal to 0. Mod represents the modulo operation or the remainder operation, and min represents the minimum value operation.

121. The base station sends downlink control information to the UE. The end subframe of the downlink control information is subframe n, and the fourth subframe after the subframe n is subframe n+4.

122. The UE receives the downlink control information sent by the base station.

123. The UE sends, to the base station, uplink data corresponding to a transport block, where the initial subframe of the uplink data is a subframe with an absolute subframe number i and a first valid uplink subframe of the subsequent subframe, the absolute subframe. The subframe with frame number i is the first subframe in subframe n+4 and subsequent subframes that satisfies the condition: i mod X=0, X=min(M,N). Information such as a modulation and coding scheme and a frequency resource used in the uplink data is indicated by the downlink control information.

124. The base station receives the uplink data sent by the UE.

In the first possible implementation, the subframe with the absolute subframe number i is a valid uplink subframe, and the initial subframe for transmitting the uplink data and the starting subframe for the uplink data mapping are both the absolute subframe number. The subframe of i. The second possible implementation is different from the first possible implementation. In the second possible implementation, the subframe with the absolute subframe number i may be a valid uplink subframe or may not be an effective uplink. Subframe. If i satisfies the condition, if the subframe whose absolute subframe number is i is a valid uplink subframe, the initial subframe to which the uplink data is transmitted is a subframe with an absolute subframe number i, and the uplink data is mapped. The initial subframe is also a subframe with an absolute subframe number i; if the subframe with the absolute subframe number i is an invalid uplink subframe, the initial subframe of the uplink data transmission is a child with an absolute subframe number i. The frame and the first valid uplink subframe in the subframe after the subframe with the absolute subframe number i, the initial subframe of the uplink data mapping is the subframe with the absolute subframe number i, but the absolute subframe number is The part of i that is to be sent on the sub-frame Row data is discarded. Therefore, when the subframe with the absolute subframe number i is an invalid uplink subframe, the second possible implementation manner is shorter than the delay of the downlink control information compared with the first possible implementation manner. low.

In an example, FIG. 11 shows that N=2, and M=2, the uplink data of one transport block is mapped to 4 RUs, and the data mapped on each RU is repeatedly transmitted 4 times, and the absolute subframe number is 6. A schematic diagram of the uplink data hopping transmission in the prior art and the second possible implementation manner of the present application, when the subframe of the 16 is an invalid uplink subframe. In FIG. 11, the end subframe of the downlink control information is a subframe with an absolute subframe number of 5, and the subframe with an absolute subframe number of 5 is a valid uplink subframe. In the prior art, the initial subframe of the uplink data transmission is a subframe with an absolute subframe number of 5. The initial subframe of the uplink data mapping is also a subframe with an absolute subframe number of 5, due to the absolute subframe. The subframe numbered 6 is an invalid uplink subframe, and the portion of the uplink data transmitted on the subframe with the absolute subframe number of 5 is repeatedly transmitted on the subframe with the absolute subframe number of 7, but the absolute subframe number is 7. The frequency resource in which the uplink data is transmitted in the subframe is hopped, and the base station cannot perform symbol level combining on the portion of the uplink data transmitted on the subframe with the absolute subframe number of 5 and the subframe with the absolute subframe number of 7. If the second possible implementation manner is adopted, the first uplink subframe that satisfies the absolute subframe number i mod 2=0 is a subframe with an absolute subframe number of 6, but the subframe with an absolute subframe number of 6 is In the case of an invalid uplink subframe, the subframe with the absolute subframe number of 6 and the first valid uplink subframe of the subsequent subframe is the subframe with the absolute subframe number of 7, and the subframe with the absolute subframe number of 7 is the subframe. The initial subframe of the uplink data transmission, but the subframe whose absolute subframe number is i, that is, the absolute subframe number is 6, is the starting subframe of the uplink data mapping, but only the subframe with the absolute subframe number of 6 is to be used. Part of the sent uplink data is discarded. Although the uplink data is discarded on some subframes, the second possible implementation may be such that the frequency resources of the same uplink data transmitted in 4 slots, ie, 2 subframes, are the same, then the base station can The portion of the uplink data transmitted on the 4 time slots is symbol-level merged.

That is, the initial subframe of the uplink data mapping of one transport block is a subframe with an absolute subframe number i, and when the subframe with the absolute subframe number i is an invalid uplink subframe, the absolute subframe number is The uplink data to be transmitted on the invalid uplink subframe between the subframe of i and the subframe of the absolute subframe number i and the subsequent first valid uplink subframe is discarded.

Similar to the first possible implementation, the second possible implementation manner may also be applicable to: uplink data to be sent on consecutive R subframes starting from the start subframe of the uplink data mapping, and the UE sends the uplink data. If there is an invalid uplink subframe in the consecutive R subframes, the UE discards the uplink data to be transmitted on the invalid uplink subframe, where R is an integer greater than 1.

I is a valid uplink subframe of i, i satisfies the condition: i mod X=0, X=min(M,N); wherein n, i, and D are integers greater than or equal to 0. Alternatively, D may be equal to one of 0, 1, 2, 3, and the like.

134. The base station receives the uplink data sent by the UE.

Different from the first possible implementation manner, in a third possible implementation manner, a delay between a start subframe of uplink data transmission corresponding to one transport block and an end subframe of downlink control information may pass the The scheduling delay included in the downlink control information is adjusted, so that the sending time of the uplink data is more flexible. The third possible implementation manner is compared with the first possible implementation manner. In the third possible implementation manner, the start subframe of the uplink data transmission is additionally delayed by D*X subframes. The start subframe of the uplink data transmission is the same as the start subframe of the uplink data mapping, and is an effective uplink subframe with an absolute subframe number i.

In an example, as shown in FIG. 12, N=2, and M=2, the uplink data of one transport block is mapped to 4 RUs, and part of the uplink data on each RU is repeatedly transmitted 4 times, and downlink control information is transmitted. The end subframe of the MPDCCH is subframe 1. When D=1, the 4+1*2 subframes after subframe 1 are subframes 1+4+2, that is, subframe 7, then the start of uplink data transmission. The subframe is a valid uplink subframe with the first absolute subframe number of 8 in subframe 7 and subsequent subframes, because the subframe with the absolute subframe number of 8 is the first subframe that satisfies the above condition. Thus, the subframe with the absolute subframe number of 8 transmits the uplink data to the data of the first RU, and the subframe with the absolute subframe number of 9 repeatedly transmits the data mapped to the first RU, and the absolute subframe number is The frequency hopping occurs at the subframe of 10, so that the frequency resources of the part of the uplink data sent by the 2*M time slots, that is, the 4 time slots are the same, that is, the uplink data is transmitted on the subframe 8 and the subframe 9 in the same manner. In part, and the frequency resources are the same, the base station may perform symbol level combining on a part of the uplink data sent on the subframe 8 and the subframe 9, similarly, the part sent on the subframe 10 and the subframe 11, the subframe 12, and the subframe 13 and the like Upstream data can be combined at the symbol level. When D=0, the 4+0*2 subframes after subframe 1 are subframes 1+4+0, that is, the 4th subframe after subframe 1 is subframe 5, then the start of uplink data transmission The subframe is a valid uplink subframe with the first absolute subframe number of 6 in the subframe after the subframe 5, and the same portion of the uplink data is transmitted on the subframe 6 and the subframe 7, the frequency resources are the same, and the subframe 8 occurs. The frequency hopping, but transmitting the different parts of the uplink data in the two subframes before and after the hopping occurs, the frequency resources of the two subframes transmitting the same data remain unchanged, and the transmission can be performed on 2*M time slots. Some of the upstream data have the same frequency resource. The base station may perform symbol level combining on a part of the uplink data sent on the subframe 6 and the subframe 7, and similarly, the uplink data sent on the subframe 8 and the subframe 9, the subframe 10, and the subframe 11 may be symbolized. Level merge.

Similar to the first possible implementation, the third possible implementation may also be applicable to: uplink data to be sent in consecutive R subframes starting from the start subframe of the uplink data mapping, and the UE sending the uplink data. If there is an invalid uplink subframe in the consecutive R subframes, the UE discards the uplink data to be transmitted on the invalid uplink subframe, where R is an integer greater than 1.

In a fourth possible implementation, the UE receives the end subframe of the downlink control information sent by the base station as the subframe n, and the scheduling delay indicated by the downlink control information is D, and the 4+ after the subframe n The D*X subframes are subframes n+4+D*X, and the starting subframe in which the UE transmits the uplink data is the subframe with the absolute subframe number i and the first valid uplink subframe in the subsequent subframe. The subframe with the absolute subframe number i is the subframe n+4+D*X and the first subframe in the subsequent subframe satisfies the condition: i mod X=0, X=min(M,N) Where n, i, and D are integers greater than or equal to zero. Alternatively, D may be equal to one of 0, 1, 2, 3, and the like.

141. The base station sends downlink control information to the UE. The end subframe of the downlink control information is subframe n, the scheduling delay indicated by the downlink control information is D, and the 4+D*X subframes after the subframe n are subframes n+4+D*X.

142. The UE receives the downlink control information sent by the base station.

143. The UE sends, to the base station, uplink data corresponding to a transport block, where the initial subframe of the uplink data is a subframe with an absolute subframe number i and a first valid uplink subframe of the subsequent subframe, and an absolute subframe. The subframe number i is the subframe n+4+D*X and the first subframe in the subsequent subframe that satisfies the condition: i mod X=0, X=min(M,N). Mod represents modulo operation or remainder operation, min Indicates the minimum value operation. Information such as a modulation and coding scheme and a frequency resource used in the uplink data is indicated by the downlink control information.

144. The base station receives the uplink data sent by the UE.

The fourth possible implementation manner is different from the second possible implementation manner. In the fourth possible implementation, the delay between the start subframe of the uplink data transmission and the end subframe of the downlink control information may be The scheduling delay included in the downlink control information is adjusted, so that the sending time of the uplink data is more flexible. Compared with the second possible implementation manner, in the fourth possible implementation, the starting subframe of the uplink data transmission is additionally delayed by D*X subframes.

In an example, as shown in FIG. 13, N=2, M=2, the uplink data corresponding to one transport block is mapped to 4 RUs, and the uplink data of each part mapped on each RU is repeatedly transmitted 4 times, the absolute sub- A subframe having a frame number of 6 and a subframe having an absolute subframe number of 16 are invalid uplink subframes. In FIG. 13, when D=1, that is, the scheduling delay indicated by the downlink control information is 1, the end subframe of the downlink control information is the subframe 1, and the 4+1*2 subframes after the subframe 1 are the sub-frames. Frame 1+4+1*2, that is, the sixth subframe after subframe 1 is subframe 7, and the subframe with absolute subframe number 8 is the first one of subframe 7 and subsequent subframes that satisfies the above conditions. In the subframe, the starting subframe in which the UE sends the uplink data is the subframe with the absolute subframe number of 8 and the first valid uplink subframe of the subsequent subframe, and the UE may send the start of the uplink data. The subframe is a subframe with an absolute subframe number of 8. Then, the subframe with the absolute subframe number of 8 is transmitted on the subframe in which the uplink data is mapped to the first RU, and the subframe with the absolute subframe number of 9 is repeatedly transmitted on the subframe with the absolute subframe number of 8. The transmitted data, the subframe with the absolute subframe number of 8 and the subframe with the absolute subframe number of 9 are the same, and the two phases of the same data are repeatedly transmitted in the subsequent subframe of the subframe with the absolute subframe number of 9. The frequency resources of the adjacent subframes are the same. Except for the part of the uplink data to be sent on the invalid uplink subframe with the absolute subframe number of 16, the frequency resources of the two adjacent subframes that send the same uplink data are the same. , the base station may perform symbol level combining on a part of the uplink data on 2*M time slots. When D=0, the fourth possible implementation is similar to the result of using the second possible implementation of the embodiment of the present application in FIG. 11, and the process is not described again.

Similar to the first possible implementation manner, the fourth possible implementation manner may also be applicable to: uplink data to be sent in consecutive R subframes starting from a starting subframe of the uplink data mapping, and the UE sending the uplink data. If there is an invalid uplink subframe in the consecutive R subframes, the UE discards the uplink data to be transmitted on the invalid uplink subframe, where R is an integer greater than 1.

The embodiment of the present application further provides a possible implementation manner, which can be applied to an FDD system, which is different from the foregoing first possible implementation manner to the fourth possible implementation manner.

In a fifth possible implementation, the UE receives the end subframe of the downlink control information sent by the base station as the subframe n, and the fourth subframe after the subframe n is the subframe n+4, and the UE sends a corresponding transport block. The starting subframe of the uplink data is a valid uplink subframe of the first absolute subframe number i in subframe n+4 and subsequent subframes, and if i mod X≠0, X=min(M,N) Then, the UE repeats the M-1 times of the uplink data mapped on the subframe with the absolute subframe number i, and obtains the uplink data to be transmitted on the 2*M time slots, and then repeats the Xi mod X. The uplink data to be transmitted on the Xi mod X subframes is obtained, wherein the subframe in which the 2*M slots are located is different from the Xi mod X subframes, and n and i are integers greater than or equal to 0.

The initial subframe of the uplink data mapping is a valid uplink subframe with an absolute subframe number i.

251. The base station sends downlink control information to the UE. The end subframe of the downlink control information is subframe n, and the fourth subframe after the subframe n is subframe n+4.

252. The UE receives the downlink control information sent by the base station.

253. The UE sends the uplink data corresponding to the transport block to the base station, and the starting subframe for sending the uplink data is the subframe n+4 and The first absolute subframe number in the subsequent subframe is a valid uplink subframe of i, and if i mod X≠0, X=min(M,N), the UE will be in the subframe with the absolute subframe number i In the upper part of the mapping, the uplink data is repeated M-1 times, and the uplink data to be transmitted on 2*M time slots is obtained, and then Xi mod X times are repeated to obtain the uplink to be transmitted on the Xi mod X subframes. Data, wherein the subframe in which the 2*M slots are located is different from the Xi mod X subframes. Mod represents the modulo operation or the remainder operation, and min represents the minimum value operation. Information such as a modulation and coding scheme and a frequency resource used in the uplink data is indicated by the downlink control information.

254. The base station receives the uplink data sent by the UE.

In an example, for the uplink data corresponding to one transport block, as shown in FIG. 14, N=2, and M=2, X=2, the uplink data of the transport block is mapped to 4 RUs, each A portion of the uplink data is repeatedly transmitted 4 times, and all subframes are valid uplink subframes. The end subframe in which the base station transmits the downlink control information MPDCCH is a subframe with an absolute subframe number of 1, and the fourth subframe after the subframe with the absolute subframe number of 1 is a subframe with an absolute subframe number of 5, then the UE sends the subframe. The starting subframe of the uplink data is a subframe with an absolute subframe number of 5 and a valid uplink subframe with a first absolute subframe number of i in the subsequent subframe, that is, i=5, but 5 mod 2≠0, Then, the UE divides the uplink data that is mapped on the subframe with the absolute subframe number of 5 by one time, and obtains the data to be transmitted on the four time slots, that is, the child with the absolute subframe number of 5 is obtained. In addition to the data to be transmitted on the subframe and the subframe with the absolute subframe number of 6, repeating 2-5 mod 2=1 times, the data to be transmitted on one subframe is obtained, wherein the children of the four slots are located. The frame is a subframe with an absolute subframe number of 5 and a subframe with an absolute subframe number of 6, and the one subframe is a subframe with an absolute subframe number of 7. In this way, the data mapped to the first RU is repeatedly transmitted three times in the first cycle, and is sent once more than the prior art, that is, one subframe is occupied, and the absolute subframe number is 6. The sub-frame and the subframe with the absolute sub-frame number of 7 transmit the same portion of the uplink data, and no frequency hopping occurs. Then, even if a frequency hop occurs in the sub-frame 8, the sub-frame 10, etc., no frequency hop occurs. If the same part of the uplink data is transmitted on the two adjacent subframes, the base station may perform symbol combination on the part of the uplink data sent on the two adjacent subframes. In this way, part of the uplink data sent on 2*M time slots can be sent on the same frequency resource. Similarly, when M>N, the first M time slots of 2*M time slots can also be sent. The frequency resources of the uplink data are the same, and the frequency resources of the uplink data sent by the last M time slots are the same.

Similar to the foregoing embodiment, the fifth possible implementation manner may be applicable to: the uplink data to be sent on consecutive R subframes starting from the start subframe of the uplink data mapping, when the UE sends the uplink data. If there is an invalid uplink subframe in the consecutive R subframes, the UE discards part of the uplink data to be sent on the invalid uplink subframe, where R is an integer greater than 1. In other words, if the sequence starts from the start subframe of the uplink data map corresponding to one transport block

If there is an invalid uplink subframe in the subframe, the uplink data to be sent in the invalid uplink subframe is discarded. N _Rep indicates the number of times the uplink data is repeatedly transmitted on each RU, and N _RU indicates the number of uplink data of one transport block mapped to the number of RUs.

Indicates the number of slots included in an RU.

It should be noted that, in the foregoing first possible implementation manner to the fifth possible implementation manner, the 2*M time slots are consecutive time slots. The uplink data to be transmitted occupies consecutive time slots. When the 2*M consecutive time slots include both the time slot in which the effective uplink subframe is located and the time slot in which the invalid uplink subframe is located, the time slots in the 2*M time slots (or the first M time slots) The time slot in the slot, or the time slot in the last M time slots) is the time slot in which the valid uplink subframe is located in the 2*M time slots (or the first M time slots, or the last M time slots) , that is, part of the time slot.

The embodiment of the present application further provides a possible implementation manner, and a sixth possible implementation manner may be applied to the TDD system. In the TDD system, one radio frame is 10 ms, including 10 1 ms subframes, and one radio frame can be divided into two fields, each of which is 5 ms.

In the TDD system, the value of N is greater than 1, and the value is a multiple of 5. For example, N can take values of 1, 5, 10, 20, or 40. The sixth possible implementation manner may also implement that when N≥M, the UE sends a transport block in the time slots in the 2*M time slots. The frequency resources of the corresponding uplink data are the same, or, when M>N, the frequency resources of the uplink data in the first M time slots of the 2*M time slots are the same, and the last M time slots are The time slot transmitting part of the uplink data has the same frequency resource.

In an example, the starting subframe in which the UE sends the uplink data is the first valid uplink subframe in the radio frame, and the first valid uplink subframe is the starting subframe of the uplink data mapping, where M is wireless. The number of valid uplink subframes in the frame. That is, in one radio frame, the uplink data is mapped from the two slots of the first valid uplink subframe of the radio frame, and the uplink data mapped to the two slots is additionally repeated M-1 times. That is, the uplink data mapped on the two time slots is transmitted in 2*M time slots, that is, all valid uplink subframes in the radio frame, and even if frequency hopping occurs in the radio frame, the first M are The frequency resources for transmitting uplink data in the time slot are the same, and the frequency resources for transmitting uplink data in the last M time slots are the same, or no frequency hopping occurs in the wireless frame. In this example, the 2*M slots are slots included in a valid uplink subframe. Assuming N=10, the uplink data transmitted on 2*M time slots is the same, and the frequency resources are also the same. As shown in FIG. 15, N=5, M=6, D represents a downlink subframe, S represents a special subframe, U represents an uplink subframe, and all uplink subframes in FIG. 15 are valid uplink subframes, and the UE sends uplink. The starting subframe of the data is the first valid uplink subframe in the radio frame (including the subframe from the absolute subframe number 0 to the subframe with the absolute subframe number 9), that is, the absolute subframe number is 2. The subframe, the subframe with the absolute subframe number of 2 is also the starting subframe of the uplink data mapping, and the number of valid uplink subframes M in the radio frame is 6, then the uplink data is repeatedly sent in 12 slots. And the frequency resources of the first six time slots in the 12 time slots are the same, and the frequency resources of the last six time slots are the same, that is, the subframes with absolute subframe numbers of 2, 3, 4, 7, 8, and 9 are repeated. Sending the uplink data to the data on the first RU, and transmitting the uplink data of the three consecutive subframes whose absolute subframe numbers are 2, 3, and 4 may be symbol-merged, and the absolute subframe number is 7. A portion of the uplink data transmitted on the three consecutive sub-frames of 8 and 9 can be symbol-merged. It can be seen that the 2*M time slots in which the uplink data is repeatedly transmitted only count the time slots of the valid uplink subframe.

In an example, the starting subframe in which the UE sends the uplink data is the first valid uplink subframe in the field, and the first valid uplink subframe is the starting subframe of the uplink data mapping, and M is half. The number of valid uplink subframes in the frame. That is to say, the valid uplink subframes in the field are used to transmit the uplink data, and the time slots in the 2*M time slots can be repeatedly transmitted in the same frequency resource. In this example, the 2*M slots are slots included in a valid uplink subframe. For example, as shown in FIG. 16, a subframe with an absolute subframe number of 0 to a subframe with an absolute subframe number of 4 constitutes a field, and the number of effective uplink subframes in the field is 3, that is, M=3, including absolute. If the subframe number is 2, 3, and 4, the hopping interval is N=5, then the UE may send the uplink data to the first RU in the same frequency resource in 2*3 or 6 time slots. Data, then the base station can perform symbol merging on the data sent in the field, and the uplink data in the latter field is mapped to the absolute subframe number of 7, when the data is repeatedly transmitted on the second RU. Sub-frames of 8 and 9 can also implement symbol merging according to this principle. It can be seen that the 2*M time slots in which the uplink data is repeatedly transmitted only count the time slots of the valid uplink subframe.

In an example, the starting subframe in which the UE sends the uplink data is the first valid uplink subframe in the field, and the first subframe in the field is the starting subframe of the uplink data mapping. Where M is 5. That is, the uplink data to be transmitted is in all types of subframes, including valid uplink subframes, invalid uplink subframes (including downlink subframes and special subframes, and subframes of non-effective uplink subframes in the uplink subframe). ) Repeat. At this time, the 2*M uplink data repeating slots are counted for consecutive absolute subframe slots, and the consecutive absolute subframes include all types of subframes. As shown in FIG. 17, the previous field includes a subframe with an absolute subframe number of 0 to a subframe with an absolute subframe number of 4, and the latter subframe includes a subframe with an absolute subframe number of 5 to an absolute subframe number. For a subframe of 9, when the uplink data corresponding to one transport block is mapped to two RUs, N=5, and M=5, the data mapped to the first RU is on all types of subframes of the previous field. Repeating to obtain data to be transmitted on all types of subframes of the previous field, and data mapped to the second RU is repeated on all types of subframes of the latter field to obtain the next field. Data to be sent on all types of subframes. The first subframe of the previous field, that is, the subframe with the absolute subframe number of 0 is the number of uplinks. According to the starting subframe of the mapping, that is, the starting subframe of the first RU. The data to be transmitted on the downlink subframe with the absolute subframe number of 0 and the special subframe with the absolute subframe number of 1 is discarded, and the downlink subframe with the absolute subframe number of 5 and the absolute subframe number of 6 are discarded. The data to be sent on the special subframe is discarded. That is, the first effective uplink subframe of the previous field, that is, the subframe with the absolute subframe number of 2 is the starting subframe of the uplink data transmission. The base station may perform symbol combining on data transmitted on valid uplink subframes with absolute subframe numbers of 2, 3, and 4, and perform symbol merging on data transmitted on valid uplink subframes of

absolute subframe numbers

7, 8, and 9. The data transmitted on the time slots in the 2*M time slots in the field is transmitted on the same frequency resource.

In an example, the starting subframe in which the UE sends the uplink data is the first valid uplink subframe in the radio frame, and the first subframe in the radio frame is the starting subframe of the uplink data mapping. Where M is 10. Similar to the previous example, the uplink data to be transmitted is in all types of subframes, including valid uplink subframes, invalid uplink subframes (including downlink subframes and special subframes, and non-effective uplink subframes in the uplink subframe). Subframe) is repeated. At this time, the 2*M uplink data repeating slots are counted for consecutive absolute subframe slots, and the consecutive absolute subframes include all types of subframes.
