Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a data transmission method, device and equipment. Background Art

[0002] The scheduling method of multiple transmission blocks (TBs), that is, one downlink control information (DCI) can schedule multiple TBs at one time. In the current version of the protocol, when scheduling TB to transmit downlink data, up to one DCI is supported to schedule 8 TBs at a time, that is, up to 8 parallel hybrid automatic repeat request (HARQ) process numbers are used at a time. In addition, the multi-TB scheduling method has a fixed scheduling delay, and the fixed scheduling delay is 2 subframes. In the Half Duplex Frequency Division Duplex (HD-FDD) mode, the network side device cannot send DCI in the two subframes before the downlink data transmission switches to the uplink data transmission, and the network side device cannot send TB in the first two subframes after the uplink data transmission switches to the downlink data transmission. These are all caused by the above-mentioned fixed scheduling delay.

[0003] Due to the fixed scheduling delay and the maximum limitation of 8 TB, the transmission rate of downlink data under the multi-TB scheduling mode of HD-FDD mode is relatively low. Summary of the invention

[0063] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0064] Currently, the downlink data transmission in the multi-TB scheduling mode of HD-FDD mode has a fixed scheduling delay and a limit of a maximum of 8 TBs per DCI. Figure 1 As shown, a multi-TB scheduling timing diagram is provided when the downlink data transmission rate is the maximum under the multi-TB scheduling mode. Specifically, if the network side device sends DCI to the electronic device through the Physical Downlink Control Channel (PDCCH) in subframe 1, and the DCI schedules 8 TBs, after a fixed scheduling delay of 2 subframes, the network side device will transmit the above 8 TBs through the Physical Downlink Shared Channel (PDSCH) in subframes 3 to 10, that is, Figure 1 In TB0~TB7, the electronic device receives the above 8 TBs on subframes 3~10 indicated by DCI, and after 1 up / downlink conversion subframe, sends confirmation (ACK) / negative confirmation (NACK) feedback of the above 8 TBs to the network side device on subframes 12~14. After that, after another up / downlink conversion subframe, the network side device sends DCI on subframe 16, and so on, to realize the scheduling of TBs by the network side device and the transmission of downlink data between the network side device and the electronic device. It should be noted that Figure 1 Subframe No. 11 and subframe No. 15 in the figure are switching subframes from downlink subframe to uplink subframe, and switching subframes from uplink subframe to downlink subframe, respectively, and no data transmission is performed.

[0065] but, Figure 1 In the multi-TB scheduling mode shown, DCI is used to schedule a maximum of 8 TBs at a time. To complete the transmission and feedback of 8 TBs, at least 15 subframes are required, so that the maximum downlink data transmission rate is only (8×1000) / 15=533.4kbps. If the number of TBs scheduled by DCI at a time is less than 8, the downlink data transmission rate will be less than 533.4kbps. At present, the single TB scheduling mode plans to introduce 14 HARQ processes, so that its maximum downlink data transmission rate can reach 705Kbps. The downlink data transmission rate under the multi-TB scheduling mode is relatively low.

[0066] Therefore, in order to avoid the fixed scheduling delay caused by, for example Figure 1 The resource waste caused by the inability to transmit downlink data in subframes 1, 2, 16, and 17 shown in the figure, in one example, two scheduling delays can be preset, namely, the first scheduling delay and the second scheduling delay. Considering compatibility, the first scheduling delay can be a fixed scheduling delay in the prior art, which is currently 2 subframes. The purpose of setting the second scheduling delay is to send a DCI before the downlink subframe is switched to the uplink subframe, and the DCI is used to make the subframe after the uplink subframe is switched to the downlink subframe transmit the DCI-scheduled TB. For example, Figure 1 For example, DCI can be sent in any subframe from subframe 2 to subframe 10 to schedule subframes 16 and 17 to transmit TB, thereby reducing resource waste and increasing the downlink data transmission rate. At this time, the second scheduling delay can be set to a subframe number from 6 to 10.

[0067] Optionally, the second scheduling delay may be 7 subframes. In this case, for example Figure 2 As shown, the electronic device can receive DCI through PDCCH in subframe 9, the DCI schedules 2 TBs, and the scheduling delay information can be the second scheduling delay, that is, 7 subframes, then the electronic device can determine that the subframes for transmitting the above 2 TBs are subframes 16 and 17. At this time, the maximum downlink data transmission rate can be increased to (10×1000) / 15=667kbps.

[0068] In order to further improve the downlink data transmission rate, the number of consecutive TBs scheduled before one feedback can be increased. At present, without considering repeated transmission of feedback information, there are 3 subframes used to transmit feedback information of consecutive TBs, and each subframe can transmit feedback information of up to 4 TBs. Therefore, if compatibility with existing technologies is considered, the number of consecutive TBs scheduled before one feedback can be up to 12. At this time, the maximum downlink data transmission rate can be increased to (12×1000) / 17=706kbps. For example Figure 3As shown:

[0069] The network side device sends a DCI to the electronic device on subframe No. 1, and the DCI scheduling delay is 2 subframes, and 8 TBs are scheduled, and the scheduled 8 TBs are transmitted on subframes No. 3 to No. 10; the network side device sends a DCI to the electronic device on subframe No. 9, and the DCI scheduling delay is 2 subframes, and 4 TBs are scheduled, and the 4 TBs are transmitted on subframes No. 11 to No. 14; thus, the network side device can schedule 12 continuously transmitted TBs through 2 DCIs; the electronic device can transmit the feedback information of these 12 TBs to the network side device on subframes No. 16 to No. 18; so far, the network side device completes the scheduling of a continuous TB, and the electronic device completes the feedback of the received information for the TB;

[0070] The network side device sends a DCI to the electronic device on subframe 13, and the scheduling delay of the DCI is 7 subframes. 4 TBs are scheduled, and these 4 TBs are transmitted on subframes 20 to 23; the network side device sends a DCI to the electronic device on subframe 22, and the scheduling delay of the DCI is 2 subframes. 8 TBs are scheduled, and these 8 TBs are transmitted on subframes 24 to 31; thus, the network side device schedules 12 continuously transmitted TBs through 2 DCIs, and the electronic device can transmit the feedback information of these 12 TBs to the network side device on subframes 33 to 35; at this point, the network side device completes the scheduling of continuous TBs, and the electronic device completes the feedback of the received information for the TBs.

[0071] In the following, for the convenience of explanation, the subframe for transmitting the feedback information of the TB is referred to as a feedback subframe. For example, the above-mentioned subframes 16 to 18 and subframes 33 to 35 can all be referred to as feedback subframes.

[0072] It should be noted that the above descriptions and examples are based on the compatibility with existing technologies so that the number of consecutive TBs is up to 12, which is not used to limit the number of consecutive TBs scheduled by this application. For example, without considering repeated transmission, and a subframe transmits a maximum of 4 TBs, since a DCI can schedule a maximum of 8 TBs, the number of consecutive TBs scheduled by two DCIs can reach 16. At this time, the feedback subframes can be increased from 3 to 4, and the scheduling of a consecutive TB and the feedback of the received information of the TB can also be completed.

[0073] Based on the above description, if the number of TBs scheduled continuously exceeds 8, it is necessary to clarify in which subframes the feedback information of the TBs is transmitted. Therefore, how the electronic device completes the transmission of the feedback information of the DCI-scheduled TBs based on the received DCI is a problem that needs to be solved.

[0074] To this end, an embodiment of the present application provides a data transmission method, which can enable an electronic device to complete the transmission of feedback information for TB after the number of scheduled consecutive TBs exceeds 8, thereby making it possible to increase the data transmission rate under a multi-TB scheduling mode.

[0075] The present application may be applicable to a variety of communication systems, such as machine-type communication (MTC) systems, long term evolution (LTE), new radio (NR), etc. The electronic devices of the present application may include but are not limited to: handheld devices, vehicle-mounted devices, wearable devices, etc. with wireless communication functions. The network side device of the present application may be a base station. In different communication systems, the implementation type of the base station may be different, which is not limited by the present application.

[0076] Figure 4 This is a flow chart of an embodiment of the data transmission method of the present application, such as Figure 4 As shown, the method may include:

[0077] Step 401: An electronic device receives a first DCI and a second DCI, both of which include feedback group information.

[0078] The first DCI and the second DCI are generally two adjacent DCIs among the DCIs received by the electronic device.

[0079] The feedback group information is used to indicate the feedback group to which the TB scheduled in the DCI belongs. A feedback group is a collection of TBs, and the feedback information of the TBs in the feedback group is transmitted on consecutive subframes. Figure 3 In the embodiment, TB0 to TB11 transmitted on subframes 3 to 14 constitute a feedback group. At this time, the feedback group information included in the DCI transmitted on subframe 1 is consistent with the feedback group information included in the DCI transmitted on subframe 9, and the feedback information of TB in the feedback group is transmitted on subframes 16 to 18. TB0 to TB11 transmitted on subframes 20 to 32 also constitute a feedback group. At this time, the feedback group information included in the DCI transmitted on subframe 13 is consistent with the feedback group information included in the DCI transmitted on subframe 22, and the feedback information of TB in the feedback group is transmitted on subframes 34 to 36; moreover, the above two feedback groups are adjacent feedback groups.

[0080] The first DCI and the second DCI may be carried by the PDCCH.

[0081] In a possible implementation, a new bit can be added to the DCI as a feedback group indicator bit, and the feedback group information in the DCI is indicated by the feedback group indicator bit. For example, in order to distinguish between two adjacent feedback groups, the feedback group information of the two adjacent feedback groups can be divided into a first group and a second group, that is, the feedback group information can include: a first feedback group and a second feedback group. At this time, the feedback group indicator bit is 1 bit, which can realize the indication of the feedback group information. When the feedback group indicator bit is 0, it indicates the first feedback group, and when the feedback group indicator bit is 1, it indicates the second feedback group. Continuing with the above example, assuming that TB0 to TB11 transmitted on subframes 3 to 14 constitute the first feedback group, and TB0 to TB11 transmitted on subframes 20 to 32 constitute the second feedback group, then the feedback group indicator bits in the DCI transmitted on subframes 1 and 9 are both 0, and the feedback group indicator bits in the DCI transmitted on subframes 13 and 22 are both 1.

[0082] Step 402: If the feedback group information of the first DCI is consistent with the feedback group information of the second DCI, the electronic device regards the TB scheduled by the first DCI and the TB scheduled by the second DCI as one feedback group, and determines the feedback subframe corresponding to the feedback group.

[0083] The above-mentioned TB can be carried by PDSCH.

[0084] The feedback subframe corresponding to the feedback group is a subframe for transmitting feedback information of TBs in the feedback group.

[0085] If compatibility with existing technologies is taken into consideration, in the embodiment of the present application, a feedback group may include a maximum of 12 TBs, that is, the first DCI and the second DCI may schedule a maximum of 12 consecutive TBs.

[0086] Step 403: the electronic device transmits feedback information of TBs in the feedback group in the determined feedback subframe.

[0087] The feedback information of the TB is used to indicate whether the TB is decoded correctly, and the feedback information of each TB can be ACK or NACK.

[0088] The step 402 of determining the feedback subframe corresponding to the feedback group may include:

[0089] Determine the binding group to which each TB in the feedback group belongs, and determine the feedback subframe corresponding to each binding group;

[0090] Then, step 403 may include: transmitting feedback information of TBs in the binding group corresponding to the feedback subframe on the determined feedback subframe.

[0091] In one possible implementation, when determining the binding group to which each TB in the feedback group belongs, the TBs in the feedback group can be divided according to a preset first number to obtain the above-mentioned binding group. The value of the first number is not limited in this application. Optionally, in order to be compatible with the existing technology, feedback information of up to 4 TBs can be transmitted based on one feedback subframe, and the first number can be 4. When dividing the binding groups according to the first number, the division can be based on the transmission order of the TBs, that is, the time sequence of the subframes where the TBs are located, or it can be divided not according to the transmission order of the TBs, for example, according to preset division rules. The TB binding group division rules can be preset in the electronic device, or can be configured by the network side device, which is not limited in this application. Continuation Figure 3 For example, assuming that the first number is 4, the binding groups are divided according to the transmission order of TB, then see Figure 5 : TB0~TB3 transmitted on subframes 3 to 6 belong to the 0th binding group, TB4~TB7 transmitted on subframes 7 to 10 belong to the 1st binding group, and TB8~TB11 transmitted on subframes 11 to 14 belong to the 2nd binding group.

[0092] The above determination of the feedback subframe corresponding to each binding group may be implemented in the following manner:

[0093] The feedback subframe corresponding to the 0th binding group can be: max{n0+l,(n L‘ +2)}, where n0 is the subframe where the last TB of the first binding group is located, l is a preset value, for example, l can be 4, n L‘ The subframe where the last TB of the feedback group is located. Figure 5 In the example shown, n0 is subframe 6, l is 4, and n L‘ is subframe No. 14, then the feedback subframe corresponding to the 0th binding group can be: max{6+4,(14+2)}=16, that is, subframe No. 16.

[0094] The feedback subframe corresponding to the b-th binding group can be: max{n b +l,s b-1 +N b-1},n b is the subframe where the last TB of the b-th binding group is located, s b-1 is the feedback subframe corresponding to the b-1th binding group, N b-1 is the number of times the feedback information of the b-1th binding group is repeatedly transmitted, where b is a natural number. Figure 5 For the example shown, if b = 1, n b The subframe where the last TB of the first binding group is located is subframe 10, s b-1 It is the feedback subframe corresponding to the 0th binding group, that is, subframe 16. Figure 5Medium b-1 is 1, then the feedback subframe corresponding to the first binding group can be max{10+4,16+1}=17, that is, subframe No. 17; the same method can be used to determine that the feedback subframe corresponding to the second binding group is subframe No. 18.

[0095] Afterwards, in step 403, the electronic device may transmit feedback information of TBs in the 0th binding group in subframe 16, feedback information of TBs in the 1st binding group in subframe 17, and feedback information of TBs in the 2nd binding group in subframe 18.

[0096] Figure 4 In the method shown, the DCI received by the electronic device carries feedback group information. The electronic device determines the feedback group based on the feedback group information in the received DCI, and then determines the feedback subframe corresponding to the feedback group, and transmits the feedback information of the TB in the feedback group on the determined feedback subframe, thereby realizing the transmission of the feedback information of the TB by the electronic device, thereby making it possible to improve the data transmission rate under the multi-TB scheduling mode.

[0097] Different from Figure 4 In the method shown in FIG. 1 , the feedback group information is carried in the DCI. In another embodiment of the present application, the feedback group information does not need to be carried in the DCI. Figure 6 As shown, it may include:

[0098] Step 601: An electronic device receives a first DCI and a second DCI.

[0099] The implementation of step 601 may refer to the description of step 401 and will not be repeated here.

[0100] Step 602: The electronic device determines that the TB scheduled by the first DCI and the TB scheduled by the second DCI are continuous;

[0101] Among them, the DCI also carries: scheduling delay information, and the number of TBs scheduled by the DCI. Based on the received DCI subframe, scheduling delay information and the number of TBs, the electronic device can calculate the subframe where the DCI scheduled TB is located, that is, the subframe in which the network side device transmits the DCI scheduled TB.

[0102] This step may include: the electronic device determines that the difference between the subframe where the last TB of the first DCI scheduling is located and the subframe where the first TB of the second DCI scheduling is located is less than a preset second value.

[0103] The specific value of the second numerical value is not limited in this application. Optionally, the second numerical value is less than or equal to 3. For example, if the second numerical value is equal to 3, the subframe where the last TB of the first DCI scheduling is located is assumed to be the nth subframe, and the subframe where the first TB of the second DCI scheduling is located can be the n+1th subframe, or the n+2th subframe, or the n+3th subframe.

[0104] Step 603: The electronic device takes the TB scheduled by the first DCI and the TB scheduled by the second DCI as a feedback group, and determines a feedback subframe corresponding to the feedback group.

[0105] The implementation of step 601 may refer to the description of step 402 and will not be repeated here.

[0106] Step 604: the electronic device transmits feedback information of the TBs in the feedback group in the determined feedback subframe.

[0107] The implementation of step 604 may refer to the description of step 403 and will not be repeated here.

[0108] Figure 6 In the method shown, the electronic device determines that the first DCI scheduled TB and the second DCI scheduled TB are continuous, takes the first DCI scheduled TB and the second DCI scheduled TB as a feedback group, determines the feedback subframe corresponding to the feedback group, and transmits the feedback information of the TB in the feedback group on the determined feedback subframe, thereby realizing the transmission of the feedback information of the TB by the electronic device, thereby making it possible to improve the data transmission rate under the multi-TB scheduling mode.
