Description

Data transmission method, device and system

Technical field

The embodiments of the present application relate to communication technologies, and in particular, to a data transmission method, device, and system.

Background technique

At present, the Long Term Evolution (LTE) system has been widely used in the field of communications, and is called the 4th Generation mobile communication technology (4G). In the LTE system, the uplink data sent by the user equipment (UE) to the base station may include PUSCH data transmitted on a Physical Uplink Shared Channel (PUSCH) and a physical uplink control channel (Physical Uplink Control). PUCCH data transmitted on the channel, PUCCH), the PUCCH data mainly includes an Uplink Control Information (UCI) and a Demodulation Reference Signal (DMRS).

In the LTE system, PUCCH data and PUSCH data are not supported to be transmitted on the same physical resource block (PRB) in different coding modes. When the PUCCH data and the PUSCH data are transmitted together, the PUCCH data and the PUSCH data are encoded together and transmitted on the PRB occupied by the PUSCH. However, the requirements of the PUCCH data and the PUSCH data for the bit error rate are substantially different, and the PUCCH data and the PUSCH data are encoded together so that the error rate of the two is consistent, and it is obviously difficult to meet the transmission requirement.

In order to meet the different requirements of the PUCCH data and the PUSCH data for the bit error rate, in the 5th Generation mobile communication technology (5G), the two are respectively transmitted by different coding methods, and the PUCCH data adopts the polarity ( The Polar code is encoded, and the PUSCH data is encoded using a Low Density Parity Check (LDPC) code. However, when the two cannot be transmitted at the same time, a large delay of uplink transmission on the UE side is caused. Therefore, in order to ensure a low delay of the uplink transmission on the UE side, how to transmit the PUCCH data and the PUSCH data in different coding modes simultaneously becomes an urgent problem to be solved.

detailed description

The method of the embodiment of the present application can be applied to an uplink transmission of an LTE system or an LTE-Advanced (LTE-A) system. The following embodiments are described by taking an LTE system as an example. FIG. 1 is a schematic structural diagram of an application scenario according to an embodiment of the present application. As shown in FIG. 1 , an LTE system includes a base station and a UE, and there may be one or more UEs in the coverage of the base station. The number is not limited. The UE may also be called a terminal, a mobile station (MS) or a mobile terminal (Mobile Terminal), etc., and the UE may be a mobile phone (or "cellular" phone) or a computer with a mobile terminal. The UE can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device that exchanges voice or data with the core network of the LTE system. In the LTE system, the uplink data sent by the UE to the base station may include PUSCH data transmitted on the physical uplink shared channel and PUCCH data transmitted on the physical uplink control channel.

As the new 5th Generation mobile communication technology (5G) enters the discussion phase, on the one hand, since the communication system is backward compatible, the new technology developed later tends to be compatible with previously standardized technologies; On the other hand, since 4G LTE already has a large number of existing designs, if it is compatible, it will inevitably sacrifice a lot of flexibility of 5G, thus reducing performance. Therefore, at present, in the 3rd Generation Partnership Project (3GPP) organization, parallel research in two directions, regardless of the backward compatible technical discussion group, is called 5G New Radio (NR).

During the discussion of the 5G NR, many companies proposed the possibility that a certain UE simultaneously transmits PUCCH data and PUSCH data to ensure a lower delay of uplink transmission on the UE side. However, if PUCCH data and PUSCH data of a certain UE are allowed to be simultaneously transmitted, it is important to allocate resources of PUCCH and PUSCH in the frequency domain. For example, if the PRB allocated by the PUCCH data and the PUSCH data is discontinuous, that is, the PRB used for transmitting the PUCCH data and the PRB used for transmitting the PUSCH data are not adjacent, interference between the two is likely to occur, thereby affecting other UEs in the intermediate frequency band. transmission.

In order to solve the above problem, the first embodiment of the present application provides a data transmission method, and FIG. 2 is a flowchart of a data transmission method according to an embodiment of the present application. As shown in FIG. 2, the method provided in this embodiment includes the following steps. :

S201. The first UE receives, by the base station, first configuration information.

The first configuration information is used to configure, for the first UE, a first time-frequency resource for transmitting the physical uplink shared channel (PUSCH) data, and a second time-frequency resource and a third time-frequency resource for transmitting the physical uplink control channel (PUCCH) data. The time domain resource of the second time-frequency resource is the same as the first part of the time domain resource of the first time-frequency resource, and the time domain resource of the third time-frequency resource is after the first time-frequency resource The time domain resources of the second time-frequency resource are not exactly the same as the time domain resources of the third time-frequency resource; the frequency of the second time-frequency resource and the third time-frequency resource The domain resources are respectively adjacent to the frequency domain resources of the first time-frequency resource.

The time-frequency resource block composed of the first time-frequency resource, the second time-frequency resource, and the third time-frequency resource is exemplarily described below with a specific illustration.

3a-3d are schematic diagrams of time-frequency resource blocks. As shown in FIGS. 3a-3d, the time-frequency resource block occupies a continuous PRB in the frequency domain and occupies 1 time slot (0.5 ms) in the time domain. For example, in FIG. 3a, the frequency domain resource of the first time-frequency resource transmitting the PUSCH data is in the middle part, and the frequency of the second time-frequency resource and the third time-frequency resource of the PUCCH data are transmitted. The domain resources are respectively located at the lower left corner and the upper right corner of the two sides adjacent to the PUSCH data. The PUCCH data is transmitted in a frequency hopping manner. In the first half of the transmission time, the PUCCH data is transmitted in a frequency domain in which the PRB label is smaller than the PRB label used by the PUSCH data. In the latter half of the transmission time, the PUCCH data is larger than the PUSCH label in the PRB label. The data is transmitted on the frequency domain of the PRB label. It should be noted that the time domain resources of the second time-frequency resource and the third time-frequency resource may not overlap (as shown in FIG. 3a), or may partially overlap (as shown in FIG. 3b). It should be noted that, in the illustration that is not shown in the first embodiment, the second time-frequency resource that transmits the PUCCH data and the frequency-domain resource that is the third time-frequency resource may also be located on both sides adjacent to the PUSCH data. The position of the upper left and lower right corners.

For example, in FIG. 3c, the frequency domain resource of the first time-frequency resource for transmitting the PUSCH data is in the middle portion, and in the PRB for transmitting the PUSCH data, the PRB with the highest label is used to transmit the PUCCH data in the first half of the time. In the second half of the time, the lowest PRB is used to transmit PUCCH data. Obviously, in the resource block shown in FIG. 3c, the first time-frequency resource for transmitting PUSCH data occupies at least three PRBs. Similarly, the time domain resources of the second time-frequency resource and the third time-frequency resource may not overlap (as shown in FIG. 3c), or may partially overlap (as shown in FIG. 3d). It can also be understood that, in the illustration not shown in the first embodiment, in the PRB in which the PUSCH data is transmitted, in the first half of the time, the lowest PRB is used to transmit the PUCCH data, and in the second half of the time. The highest PRB is used to transmit PUCCH data.

It is worth mentioning that the PUCCH data is transmitted in two parts, and the frequency diversity is improved by using the frequency hopping method to transmit the PUCCH data.

It should be noted that the examples shown in FIG. 3a to FIG. 3d are only the size of a time-frequency resource block defined in the LTE system. With the evolution of the network architecture and the emergence of new application scenarios, for example, a new radio access network (New Radio) In Access Technical, New RAT) or NR, the time-frequency resource block may have a new definition, for example, the time taken in the time domain is longer or shorter, and this application limits this.

S202. The first UE sends the PUSCH data to the base station by using the first time-frequency resource, and uses the second time-frequency resource and the third time-frequency resource to send the PUCCH data to the base station by using a frequency hopping manner.

S203. The base station receives the PUSCH data sent by the first UE on the first time-frequency resource, and receives the PUCCH data sent by the first UE on the second time-frequency resource and the third time-frequency resource.

The data transmission method provided in this embodiment transmits the PUCCH data and the PUSCH data of the UE simultaneously on the adjacent PRBs, not only ensuring the lower delay of the uplink transmission on the UE side, but also the PRB and the PUSCH used for transmitting the PUCCH data. The PRBs used for the data are adjacent, so it is also possible to effectively reduce interference to other frequency bands, thereby reducing the impact on other UEs.

When the PUCCH data of a certain UE is transmitted on the adjacent sides of the frequency band occupied by the PUSCH data, since the resources for transmitting the PUSCH data are independently allocated to a certain UE, only the UE knows the frequency domain location of the resources used by the PUCCH. . Based on this, in order to further improve the utilization of the spectrum resources, the embodiment of the present application also provides a scheme for multiplexing UEs with different PUCCH resources when the PUCCH and the PUSCH are transmitted together.

FIG. 4 is a schematic diagram of multiplexing PUCCH transmission resources of different UEs according to an embodiment of the present disclosure. When different UEs respectively use the time-frequency resource blocks shown in FIG. 3a (or 3b) and FIG. 3c (or 3d) to transmit respective PUSCH data and For PUCCH data, the manner in which PUCCH resources are multiplexed is as shown in FIG. 4. The UE1, the UE2 and the UE3 respectively transmit the respective PUSCH data and the PUCCH data in the frequency domain, wherein the UE1 adopts the time-frequency resource block shown in FIG. 3c, and the UE2 and the UE3 adopt the time-frequency resource block shown in FIG. 3a. During the specific transmission process, UE2 transmits its PUCCH data while transmitting its PUSCH data, and the PUCCH data transmitted in the first half slot is the same as the PUCCH data of UE1. PRB. When transmitting its PUSCH data, UE3 simultaneously transmits its PUCCH data, and the PUCCH data transmitted by UE3 and the PUCCH data of UE1 are multiplexed with the same PRB in the latter half of the time slot. In other words, when transmitting its PUSCH data, UE1 simultaneously transmits its PUCCH data, multiplexes with the PUCCH resource of UE2 in the first half of the time slot, and multiplexes with the PUCCH resource of UE3 in the second half of the time.

It can be understood that different UEs can distinguish different UEs by using different spreading sequences or code domain sequences in the process of multiplexing PUCCH resources. For example, the spreading sequence or code domain sequence used by UE1, UE2, and UE3 in transmitting PUCCH data may be specified by the standard or indicated by the base station.

Obviously, FIG. 4 is only schematically illustrated by using the time-frequency resource block shown in FIG. 3a and FIG. 3c as an example, when different UEs adopt FIG. 3b and FIG. 3d, or 3a and FIG. 3d, or or 3b and FIG. 3c respectively. When the time-frequency resource block transmits the respective PUSCH data and the PUCCH data, the multiplexing principle is similar to the multiplexing principle shown in FIG. 4, and details are not described herein again.

In the embodiment shown in FIG. 4, different UEs need to introduce time-frequency resource blocks shown in FIG. 3a to 3d when multiplexing PUCCH transmission resources. For example, only different UEs use FIG. 3a (or 3b) and FIG. 3c respectively. The PUCCH resource multiplexing can be implemented only when the time-frequency resource block shown in 3d) transmits the respective PUSCH data and the PUCCH data. In order to realize that different UEs are not limited by the form of time-frequency resource blocks when multiplexing PUCCH transmission resources, various multiplexing schemes as shown in FIG. 5 to FIG. 10 are also provided in the following embodiments of the present application.

When transmitting its PUSCH data, the UE simultaneously transmits its PUCCH data on the PRB adjacent to the PRB transmitting the PUSCH data. In this embodiment, the PRB for transmitting PUCCH data adjacent to the PRB transmitting the PUSCH data is referred to as a neighboring PUCCH resource, and the corresponding data is referred to as adjacent PUCCH data. At the same time, there may be other UEs that only have PUCCH data transmission, and these UEs can transmit their PUCCH data by using the two sides of the entire frequency band PRB. In this embodiment, we refer to the PRBs used to transmit PUCCH data on both sides of the entire frequency band as sideband PUCCH resources, or we refer to PUCCH resources other than the adjacent PUCCH as the sideband PUCCH resources, correspondingly The data is called sideband PUCCH data.

FIG. 5 is a schematic diagram of multiplexing PUCCH transmission resources of different UEs according to an embodiment of the present disclosure. As shown in FIG. 5, a first half of a neighboring PUCCH resource is multiplexed with a sideband PUCCH resource, that is, a code domain resource on the PUCCH resource. A portion of the adjacent PUCCH data is occupied, and the remaining portion of the code domain resource is used for sideband PUCCH data transmission. The code domain resources occupied by different PUCCH data may be specified by a standard or indicated by a base station.

As shown in FIG. 6, the first half and the second half of the adjacent PUCCH resources are respectively multiplexed with the sideband PUCCH resources. The code domain resources occupied by different PUCCH data may be specified by a standard or indicated by a base station.

7 is a schematic diagram of a neighboring PUCCH data of a single UE and a PUCCH transmission resource of a sideband PUCCH data. As shown in FIG. 7, the base station allocates a PRB in the middle of the frequency band to the UE1 to transmit PUSCH data, and the base station instructs the UE1 to transmit the PUSCH of the UE1. The PUCCH data is transmitted on the PRBs on the two sides of the data, and the code domain resources used by the UE1 to transmit the PUCCH data are indicated. When the other UEs only transmit the PUCCH data, the base station may schedule other UEs to transmit the PUCCH data in the location where the UE1 transmits the PUCCH data. The code domain resources used by other UEs are different from the code domain resources used by UE1. Optionally, there are PUCCH resources on the same frequency band of the same PRB as the PUCCH resource of the UE1, and the base station may also schedule other UEs to transmit the PUCCH data on the PUCCH resources.

As an optional implementation manner, when the UE1 needs to transmit more PUCCH data, the PUCCH resource occupied by the UE1 may not be multiplexed with other UEs. At this time, the base station schedules UE1 to fill in the grid shown in FIG. The PUCCH data is transmitted on the charging part of the PUCCH resource. The base station schedules other UEs to transmit their PUCCH data on the PUCCH resource with the twill padding portion shown in FIG. After receiving the signal on the base station side, if multiple UEs are multiplexed with PUCCH resources, the received signal is multiplied by the code domain resource corresponding to UE1 to decode the UCI of UE1. If only UE1 transmits its PUCCH data on the PUCCH resource, the base station directly decodes the received signal to obtain the UCI of UE1.

As shown in FIG. 8, the base station allocates PRBs in the middle of the frequency band for transmitting PUSCH data to UE1 and UE2, respectively. UE1 and UE2 respectively transmit their PUCCH data on PRBs adjacent to each other on which the PUSCH data is transmitted.

The base station schedules other UEs to transmit PUCCH data on the time-frequency resources of the UE2 transmitting PUCCH data in the second half of the time slot, and the code domain resources used by other UEs are different from the code domain resources used by the UE2. On the receiving side, the base station receives signals on each PUCCH resource and decodes them.

As an optional implementation manner, UE1 and UE2 can use the same code domain resource on the sideband PUCCH resource, and the two can be distinguished by different PRBs, so that the code domain resource on the sideband PUCCH resource can be reduced. Occupied. The transmission resources of another part of PUCCH data of UE1 and UE2 are located on different time domain resources of the same PRB. Other PUCCH resources on both sides of the entire frequency band, that is, on the same PRB time domain symbol as the PUCCH resource of the first half slot of UE1 and on the same PRB time domain symbol as the PUCCH resource in the second half slot of UE2, the base station scheduling Other UEs transmit their PUCCH data on these sideband PUCCH resources.

In still another embodiment of the present application, a certain PRB in the middle of the frequency band may be fixed by the standard specification or the base station for transmitting the PUCCH data. When the base station presets the PRB for transmitting the PUCCH data, the base station may implicitly indicate by the preset time slot type. After the PRB fixed for transmitting the PUCCH data is preset, the base station can achieve the effect of improving transmission efficiency by scheduling the UE without PUSCH transmission to multiplex the PUCCH data on the preset PRB.

The base station schedules the UE1 to transmit its PUCCH data on the third group of PUCCH resources on both sides of its PUSCH data, and the code domain resources used by the UE1 may be specified by the base station or standard. The base station schedules the UE2 to transmit its PUCCH data on the second group of PUCCH resources on both sides of the PUSCH data, and the code domain resources used by the UE2 may be preset by the base station or standard. For other UEs that only transmit PUCCH data, the base station schedules other UEs to transmit their PUCCH data on the first group, the second group, and the third group of PUCCH resources.

Among them, [w0, w1] constitutes a code domain sequence, which can be used for code division into different UEs.

In the following embodiments, how to multiplex PUCCH resources when different UEs transmit PUCCH data in the same transmission format or different transmission formats will be explained in detail. The PUCCH resource multiplexing mode in which PUCCH data is transmitted by different UEs in the same transmission format is as shown in FIG. 15 or FIG. 16 , and the PUCCH resource multiplexing manner in which different UEs use different transmission formats to transmit PUCCH data is as shown in FIG. 17 or FIG. 18 . Show.

15 is a schematic diagram of a PUCCH resource multiplexing manner in which different UEs transmit PUCCH data in the same transmission format. As shown in FIG. 15, UE1 and UE2 respectively transmit a small amount of data, and adopt the transmission mode shown in FIG. 12 and the transmission format shown in FIG. The encoding processing flow above and below the 7 symbols for transmitting PUCCH data shown in FIG. 15 respectively corresponds to the encoding processing of the PUCCH data of UE1 and UE2. For example, in FIG. 15, UE1 and UE2 may adopt different spreading sequences of length 12, and the spreading sequences of UE1 and UE2 are orthogonal to each other. Or UE1 and UE2 may respectively adopt different code domain sequences [w0, w1], for example, UE1 adopts code domain sequence [w0, w1]=[1,-1], UE2 adopts code domain sequence [1,1]; or UE1 Using the code domain sequence [w0, w1] = [1, 1], UE2 uses the code domain sequence [w0, w1] = [1, -1]. Further, after the receiving end receives the PUCCH data, if UE1 and UE2 adopt different code domain sequences, the signal received by the receiving end is multiplied by the corresponding code domain sequence to distinguish the signals of UE1 and UE2, and then DFT is performed. Multiply the corresponding spreading sequence and combine to obtain the transmitted UCI. If UE1 and UE2 use the same code domain sequence, the signal received by the receiving end is multiplied by the corresponding spreading sequence and combined to obtain the transmitted UCI.

As shown in FIG. 16, UE1 and UE2 respectively transmit a large amount of data, and the coding mode shown in FIG. 13 or FIG. 14 is used, as shown in FIG. 11a. Transport format. The encoding process flow above the 7 symbols for transmitting PUCCH data shown in FIG. 16 corresponds to the encoding process of the PUCCH data of the UE1, and the lower encoding process flow corresponds to the encoding process of the PUCCH data of the UE2. For example, in FIG. 16, UE1 transmits 36N QPSK signals in the coding mode shown in FIG. 13, and UE2 transmits 12N QPSK signals in the coding mode shown in FIG. UE1 and UE2 respectively use different code sequence [w0, w1], for example, UE1 adopts code domain sequence [w0, w1] = [1, -1], UE2 adopts code domain sequence [1, 1]; or UE1 adopts The code domain sequence [w0, w1] = [1, 1], UE2 uses the code domain sequence [w0, w1] = [1, -1]. Further, after receiving the signal, the receiving end multiplies the corresponding code domain sequence to distinguish the signals of UE1 and UE2, and then obtains the transmitted UCI through DFT and IDFT.

17 is a schematic diagram of a PUCCH resource multiplexing manner in which different UEs transmit PUCCH data in different transmission formats, where an encoding process flow above 7 symbols for transmitting PUCCH data shown in FIG. 17 corresponds to encoding of PUCCH data of UE1. Processing, the lower encoding processing flow corresponds to encoding processing of PUCCH data of UE2. As shown in FIG. 17, UE1 transmits 36N QPSK signals in the coding mode shown in FIG. 13, and transmits DMRS on one symbol in the middle; UE2 transmits one QPSK signal in the coding mode shown in FIG. 12, and three in the middle. The DMRS is transmitted on the symbol. UE1 and UE2 respectively use different code sequence [w0, w1]. It is worth mentioning that UE1 uses the code domain sequence [w0, w1] = [1, -1], and UE2 uses the code domain sequence [w0, w1] = [1, 1]. Since the spreading sequence used in DMRS in LTE is [1, 1, 1], in order to support such a spreading sequence, the code domain sequence used by UE2 can only satisfy [w0, w1] = [1, 1]. Claim. Further, after receiving the signal, the receiving end multiplies the corresponding code domain sequence to distinguish the signals of UE1 and UE2, and then obtains the transmitted UCI through DFT and IDFT.

18 is a schematic diagram of a PUCCH resource multiplexing manner in which different UEs transmit PUCCH data in different transmission formats, where an encoding process flow above 7 symbols for transmitting PUCCH data shown in FIG. 18 corresponds to encoding of PUCCH data of UE1. Processing, the lower encoding processing flow corresponds to encoding processing of PUCCH data of UE2. As shown in FIG. 18, UE1 transmits 12N QPSK signals in the coding mode shown in FIG. 14, and transmits DMRS on one symbol in the middle; UE2 transmits one QPSK signal in the coding mode shown in FIG. 12, and three in the middle. The DMRS is transmitted on the symbol. UE1 and UE2 respectively use different code sequence [w0, w1]. As described above, UE1 uses the code domain sequence [w0, w1] = [1, -1] at this time, and UE2 uses the code domain sequence [w0, w1] = [1, 1]. Since the spreading sequence used in DMRS in LTE is [1, 1, 1], in order to support such a spreading sequence, the code domain sequence used by UE2 can only satisfy [w0, w1] = [1, 1]. Claim. Further, after receiving the signal, the receiving end multiplies the corresponding code domain sequence to distinguish the signals of UE1 and UE2, and then obtains the transmitted UCI through DFT and IDFT.

It is adjacent to the PRB used to transmit PUSCH data, so it can also effectively reduce interference generated to other frequency bands, thereby reducing the impact on other UEs. Further, in order to improve the utilization of the spectrum resources, the embodiment of the present application also provides a scheme for multiplexing UEs with different PUCCH resources when the PUCCH and the PUSCH are transmitted together. Different UEs use different forms of time-frequency resource blocks to transmit PUCCH data and PUSCH data simultaneously, so that different UEs can multiplex PUCCH resources. By multiplexing the adjacent PUCCH resources and the sideband PUCCH resources, the adjacent PUCCH is effectively avoided.
