Description

TECHNICAL FIELD

[0002] In the blind retransmission scheme provided by the prior art, after the terminal device performs initial transmission on data, it does not need to wait for the retransmission uplink authorization of the base station, but can directly perform uplink retransmission in other idle time slots. However, if there are not many uplink time slots, or there is no continuous uplink time slot available for uplink retransmission after initial transmission, the terminal device needs to wait for an idle time slot to be able to perform uplink retransmission, thereby causing a large transmission delay.

[0124] To solve the problem that the terminal device needs to wait for an idle time slot before performing uplink retransmission when the existing blind retransmission technology has few uplink time slots or there is no continuous uplink time slot available for uplink retransmission after initial transmission, and the transmission delay is large, the embodiment of the present disclosure provides a sending method, device and apparatus of uplink data and a medium.

[0128] S11, the terminal device receives the uplink authorization information sent by the network device, and the uplink authorization information includes a plurality of different RV information and uplink control information.

[0129] ​The terminal device involved in the embodiments of the present disclosure can refer to a device that provides video, voice and / or data connectivity to users, a handheld device with wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device can also be different.

The wireless terminal device can be a USB storage device, other personal computer memory devices and a dongle, and can also communicate with one or more core networks (Core Network, CN) through a radio access network (Radio Access Network, RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (also known as a “cellular” phone) and a computer with a mobile terminal device, for example, it can be a portable, pocket, handheld, computer built-in or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, personal communication service (Personal Communication Service, PCS) phones, cordless phones, session initiated protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDA), personal computers, tablet computers, machine type communication (Machine-type Communication, MTC) terminal devices, etc. The wireless terminal device can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, and a wireless access device and router / modem that meet the limitations of the present definition, etc. The embodiments of the present disclosure are not limited.

[0130] In the embodiments of the present disclosure, the terminal device includes a plurality of transmit panels, and supports transmitting the content of the same transport block to one or more network devices through the plurality of transmit panels at the same time.

[0131] In some embodiments, the network device referred to in the embodiments of the present disclosure can be a base station, which can include multiple cells serving terminals. According to different specific application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The base station referred to in the embodiments of the present disclosure can be used to exchange received air frames and Internet Protocol (IP) packets as a router between wireless terminal devices and the rest of the access network, which can include an Internet Protocol (IP) communication network. The base station can also coordinate the management of properties of the air interface. For example, the base station referred to in the embodiments of the present disclosure can be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture, and the like, and can also be a home evolved Node B (HeNB), a relay node, a femto, a pico, a network test device, and the like, which are not limited in the embodiments of the present disclosure. In some network structures, the base station referred to in the embodiments of the present disclosure can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart. Of course, in other embodiments, the network device referred to in the embodiments of the present disclosure can not be limited to a base station, for example, in other embodiments, the network device referred to in the embodiments of the present disclosure can also be any one of an air platform (such as a drone, a satellite, and the like), a transmission point, a DU, or a baseband signal processing unit (Base Band Unit, referred to as BBU).

[0132] The network device referred to in the embodiments of the present disclosure, also referred to as a target network device, is configured to send uplink authorization information to a terminal device, and receive a data stream of a PUSCH generated by the terminal device. The uplink authorization information at least includes information of multiple different RVs and uplink control information.

[0133] The uplink control information includes all control information used to control uplink transmission, such as time domain resources, frequency domain resources, code rates, and the like. The specific content of the uplink transmission control information referred to in the embodiments of the present disclosure can be referred to related technologies, which will not be described here.

[0134] The information of multiple different RVs in the uplink grant information can be carried in a preset field. The number of bits of the preset field is the same as the number of RVs, and each bit in the preset field is used to reflect the information of an RV. Taking two RVs as an example, the preset field corresponding to the two RVs includes two bits, and when the values of the two bits are 01, the bit with a value of "0" indicates that the value of the RV is 0, and the bit with a value of "1" indicates that the value of the RV is 2. The case of three or more RVs can refer to the case of two RVs, which will not be described here. It should be noted that in the multiple different RVs indicated by the uplink control information, at least one RV corresponds to a data stream containing the entire content of the transport block, and the data streams corresponding to other RVs can contain part of the content of the transport block.

[0135] In some embodiments, the following processing rule of the terminal device can be preset: if the uplink grant information received by the terminal device includes information of multiple different RVs, the terminal device generates a data stream of PUSCH corresponding to each RV in the uplink grant information based on the information of multiple different RVs in the uplink grant information and the uplink control information, and sends the multiple data streams of PUSCH corresponding to the multiple different RVs to the network device in the same time slot.

[0136] By presetting the above processing rule, the terminal device can not need to be instructed to send the content of the same transport block through multiple PUSCHs with different RVs through an additional communication process, and the terminal device can not need to carry corresponding indication information in the uplink grant information to instruct the terminal device to send the content of the same transport block through multiple PUSCHs with different RVs, thereby simplifying the communication process and reducing the amount of information of the uplink grant information.

[0137] In other embodiments, the uplink grant information can further include first indication information, which is used to instruct the terminal device to send the content of the same transport block through multiple PUSCHs with different RVs. After receiving the uplink grant information, the terminal device can generate a data stream of PUSCH corresponding to each RV indicated by the uplink grant information according to the first indication information, and send the multiple data streams of PUSCH corresponding to the multiple different RVs indicated by the uplink grant information to the network device in the same time slot.

[0138] For example, in some examples, the uplink grant information referred to by embodiments of the present disclosure can multiplex the format of downlink control information (DCI) and carry the first indication information in the reserved field of the format. Taking the format 0_1 (format 0_1) of DCI as an example, the uplink grant information can multiplex the format 0_1 of DCI, and the format 0_1 can carry control information of a transport block, which can include an RV field, a new data indication (NDI) field, and a sounding reference signal (SRS) resource set indicator field. Among them, each bit of the RV field corresponds to a value of an RV, and the number of bits contained in the RV field is the number of RVs. The NDI field is used to carry the third indication information, and the third indication information is used to indicate that the multiple RVs in the RV field are applied to the transmission of the same transport block. The SRS resource set indicator field is used to indicate the mapping relationship between the SRS resource set indicator and the SRS resource configuration, and in addition, the SRS resource set indicator field is also used to indicate that the terminal device transmits the data of the same transport block through multiple RV different PUSCHs.

[0139] For another example, in some examples, the uplink grant information multiplexes the format of DCI, and carries the first indication information through a self-defined field in the format.

[0140] By carrying the first indication information in the uplink grant information, the first indication information is used to indicate that the terminal device transmits the content of the same transport block through multiple RV different PUSCHs, and the first indication information does not need to be transmitted through a special communication process, which can simplify the communication process and improve the communication efficiency.

[0141] S12, the terminal device generates multiple physical uplink shared channel (PUSCH) data streams corresponding to multiple different RVs based on the received multiple different RV information and the uplink control information.

[0142] Among them, the multiple PUSCH data streams generated by the terminal device contain the content of the same transport block, and different PUSCHs correspond to different RVs.

[0143] The terminal device can encode the data to be transmitted according to the code rate contained in the uplink control information, and perform interleaving processing on the encoded data to obtain interleaved data, and then input the interleaved data into a circular buffer. The data in the circular buffer is referred to as a transport block in the embodiments of the present disclosure. The data in the circular buffer can be divided into multiple redundancy versions, and each redundancy version (i.e., RV) corresponds to a starting point. For example, Figure 2 is a schematic diagram of a circular buffer provided by the embodiments of the present disclosure. In Figure 2 , the data in the circular buffer is exemplarily divided into four redundancy versions, i.e., RV equal to 0, RV equal to 1, RV equal to 2, and RV equal to 3. Among them, RV equal to 0, RV equal to 1, RV equal to 2, and RV equal to 3 correspond to a starting point, respectively. In RV equal to 0, the data stream of PUSCH with RV equal to 0 is obtained by starting from the starting point of RV equal to 0 (i.e., the position of "0" in Figure 2 ) and obtaining data from the circular buffer in a clockwise direction until the number of bits indicated in the uplink control information (such as 100 bits, but not limited to 100 bits) is obtained. In RV equal to 1, the data stream of PUSCH with RV equal to 1 is obtained by starting from the starting point of RV equal to 1 (i.e., the position of "1" in Figure 2 ) and obtaining data from the circular buffer in a clockwise direction until the number of bits indicated in the uplink control information (such as 100 bits, but not limited to 100 bits) is obtained. In RV equal to 2, the data stream of PUSCH with RV equal to 2 is obtained by starting from the starting point of RV equal to 2 (i.e., the position of "2" in Figure 2 ) and obtaining data from the circular buffer in a clockwise direction until the number of bits indicated in the uplink control information (such as 80 bits, but not limited to 80 bits) is obtained. In RV equal to 3, the data stream of PUSCH with RV equal to 3 is obtained by starting from the starting point of RV equal to 3 (i.e., the position of "3" in Figure 2 ) and obtaining data from the circular buffer in a clockwise direction until the number of bits indicated in the uplink control information (such as 200 bits, but not limited to 200 bits) is obtained. It can be known from Figure 2 that in some embodiments, the data stream with RV equal to 0 and the data stream with RV equal to 1 can have some bits in common, the data stream with RV equal to 1 and the data stream with RV equal to 2 can have some bits in common, the data stream with RV equal to 2 and the data stream with RV equal to 3 can have some bits in common, and the data stream with RV equal to 3 and the data stream with RV equal to 1 can have some bits in common. The data streams of PUSCH with different RVs can improve the success rate of decoding and obtain coding gain.

[0144] S13, the terminal device transmits the multiple PUSCH data streams to the network device through the multiple transmit panels simultaneously.

[0145] For example, Figure 3 is a schematic diagram of a sending method of uplink data provided by an embodiment of the present disclosure. In Figure 3 The terminal device includes multiple transmit panels, one or more of which also have signal receiving functions. The terminal device receives uplink grant information sent by the network device through one of the transmit panels (specifically, transmit panel 1 in the figure). Figure 3 The terminal device generates a PUSCH data stream with RV equal to 0 and a PUSCH data stream with RV equal to 2. The PUSCH data stream with RV equal to 0 can be transmitted to the network device through transmit panel 1, for example; in the same time slot, the PUSCH data stream with RV equal to 2 can be transmitted to the network device through transmit panel 2, for example.

[0146] Of course, this is only an example using two different RVs as an example, and is not the only limitation. The sending method when there are more RVs, such as 3 or 4 different RVs, can refer to the sending method of the two RVs described above, and will not be described here.

[0147] The embodiment of the present disclosure can reduce the transmission delay of blind retransmission, improve the transmission efficiency, and obtain coding gain by carrying the information of multiple different RVs in the uplink grant information and the uplink control information, and enabling the terminal device to generate multiple PUSCH data streams corresponding to multiple different RVs based on the information of multiple different RVs and the uplink control information, and transmitting the multiple PUSCH data streams to the network device through multiple transmit panels simultaneously.

[0148] Figure 4 is a schematic diagram of another sending method of uplink data provided by an embodiment of the present disclosure. As Figure 4 The sending method of uplink data provided by an embodiment of the present disclosure can include the following steps in some embodiments:

[0149] S41, the base station sends uplink grant information to the network device 1, and the uplink grant information includes the information of multiple different redundancy versions RV and uplink control information.

[0150] The network device 1 can be a relay device, for example. The network device 1 can be any one of an aerial platform (such as a drone, a satellite, etc.), a transmission point, a DU, or a baseband signal processing unit (BBU).

[0151] The base station in the embodiments of the present disclosure can be understood as a base station of a cell where the terminal device is located.

[0152] In the embodiments of the present disclosure, the base station forwards the uplink authorization information to the terminal device through the network device 1.

[0153] S42, the network device 1 forwards the uplink authorization information to the terminal device.

[0154] S43, the terminal device generates a plurality of PUSCH data streams corresponding to a plurality of different RVs based on the information of a plurality of different RVs included in the uplink authorization information and the uplink control information.

[0155] The plurality of PUSCH data streams generated by the terminal device contain the content of the same transport block, and different PUSCHs correspond to different RVs.

[0156] S44, the terminal device simultaneously sends the plurality of PUSCH data streams to the target network device 1 and the target network device 2 based on a plurality of transmission faces.

[0157] The target network device 1 and the target network device 2 in the embodiments of the present disclosure can be understood as a relay device that has established a connection with the terminal device and the base station in advance, and the relay device can forward the uplink data of the terminal device to the base station. The target network device 1 and the target network device 2 can be any one of an aerial platform (such as a drone, a satellite, etc.), a transmission point, a DU, or a baseband signal processing unit (BBU).

[0158] It should be noted that in the embodiments of the present disclosure, the network device 1 is not a target network device and does not receive the PUSCH data stream generated by the terminal device, but in other embodiments, the network device 1 can also serve as a target network device and receive the PUSCH data stream corresponding to one or more RVs sent by the terminal device.

[0159] In the embodiments of the present disclosure, the number of PUSCH data streams generated by the terminal device can be greater than or equal to 2. When it is equal to 2, the target network device 1 and the target network device 2 each receive one PUSCH data stream. If it is greater than 2, at least one of the target network device 1 and the target network device 2 receives a plurality of PUSCH data streams.

[0160] In some embodiments, the base station can send the fourth indication information to the terminal device through a radio resource control (RRC) parameter, and the fourth indication information is used to indicate the uplink transmission control indication (UL-TCI) adopted by each RV in the uplink grant information. The UL-TCI is used to indicate the uplink beam of the terminal device sending the PUSCH, and the uplink beam corresponds to the corresponding network device (i.e., the target network device in the embodiments of the present disclosure). For example, the RRC configuration parameter can be a spatial division multiplexing-different RV-uplink transmission control indication mode (SDM-DiffRV-ULTCIMode). If the SDM-DiffRV-ULTCIMode is configured as “true”, the PUSCH data stream with the smallest RV value is sent to the network device with the lowest UL-TCI binding, the PUSCH data stream with the second smallest RV value is sent to the network device with the second lowest UL-TCI binding, and so on, and the PUSCH data stream with the largest RV value is sent to the network device with the highest UL-TCI binding. If the SDM-DiffRV-ULTCIMode is configured as “false”, the PUSCH data stream with the smallest RV value is sent to the network device with the highest UL-TCI binding, the PUSCH data stream with the second smallest RV value is sent to the network device with the second highest UL-TCI binding, and so on, and the PUSCH data stream with the largest RV value is sent to the network device with the lowest UL-TCI binding. Here, the high and low of the UL-TCI refer to the size of the TCI index in the UL-TCI, and the large is the high UL-TCI and the small is the low UL-TCI.

[0161] In other embodiments, no additional RRC parameter indication is needed, but the UL-TCI adopted by different RVs is determined according to a predefined rule. For example, the terminal device receives a physical downlink control channel (PDCCH) containing uplink grant information, and then the terminal device knows the corresponding coreset of the PDCCH, so that the corresponding TCI can be determined according to the correspondence between the coreset and the TCI, for example, TCI-ID0, so that the terminal device sends the data stream of the PUSCH with one of the RV values (such as the PUSCH with the largest or smallest RV value) to the network device (such as the network device 1) bound by the TCI (TCI-ID0), and the data stream of the PUSCH with other RV values can be sent to one or more other network devices that have established a connection with the terminal device and the base station.

[0162] S45, the target network device 1 and the target network device 2 forward the received PUSCH data stream to the base station.

[0163] For example, Figure 5 is a schematic diagram of another sending manner of uplink data provided by the embodiment of the present disclosure. In the sending manner shown in Figure 5 The terminal device includes multiple transmitting panels, one or more of which also have signal receiving functions. The base station sends uplink authorization information to the network device 1. The terminal device receives the uplink authorization information forwarded by the network device 1 through one of the transmitting panels (specifically, the transmitting panel 1 in the embodiment). Figure 5 Suppose the information of the RV contained in the uplink authorization information is RV equal to 0 and RV equal to 2. Then the terminal device generates a data stream of PUSCH with RV equal to 0 and a data stream of PUSCH with RV equal to 2. The data stream of PUSCH with RV equal to 0 can be sent to the network device 1 through the transmitting panel 1 by way of example; in the same time slot, the data stream of PUSCH with RV equal to 2 can be sent to the network device 2 (another network device connected with the terminal device and the base station and capable of being used as a relay) through the transmitting panel 2 by way of example. Then the network device 1 and the network device 2 respectively send the data stream of PUSCH with RV equal to 0 and the data stream of PUSCH with RV equal to 2 to the base station. Of course, Figure 5 This is only an example and is not the only way.

[0164] It should be noted that Figure 4 The embodiment is only an example with two target network devices, and in other implementations, the number of target network devices can not be limited to two, such as three or four, or more. In the case of more target network devices, the implementation and benefits are similar to the case of two target network devices, which will not be described here.

[0165] The embodiment of the present disclosure carries information of multiple different RVs in the uplink authorization information and uplink control information, so that the terminal device generates multiple data streams of PUSCH corresponding to multiple different RVs based on the information of multiple different RVs and the uplink control information, and simultaneously sends the multiple data streams of PUSCH to multiple target network devices through multiple transmitting panels. The multiple target network devices send multiple data streams containing the content of the same transport block to the base station, which can reduce the transmission delay of blind retransmission, improve transmission efficiency, and obtain coding gain to improve transmission performance.

[0166] As can be seen from the above Figure 1 and Figure 4 embodiments, in some implementations, the above Figure 1 and Figure 4The scheme can be summarized as: a terminal device receives uplink authorization information sent by a network device, the uplink authorization information including information of multiple different redundancy versions (RVs) and uplink control information; the terminal device generates multiple PUSCH data streams corresponding to the multiple different RVs based on the information of the multiple different RVs and the uplink control information, the multiple PUSCH data streams containing the content of a same transport block; and the terminal device simultaneously sends the multiple PUSCH data streams to one or more target network devices through multiple transmit panels.

[0167] Figure 6 is a schematic diagram of an uplink authorization information sending method provided by an embodiment of the present disclosure. As shown in Figure 6 , in some embodiments, the uplink authorization information sending method can include:

[0168] S61, the terminal device sends an SRS signal to the network device.

[0169] S62, the network device compares the received power and / or signal-to-noise ratio of the SRS signal with a preset threshold to obtain a comparison result.

[0170] The method for the network device to determine the received power and / or signal-to-noise ratio of the SRS signal can refer to the prior art, which will not be described here.

[0171] S63, the network device sends the comparison result to a base station accessed by the terminal device.

[0172] S64, when the comparison result is that the received power and / or signal-to-noise ratio is less than the preset threshold, the base station sends uplink authorization information to the network device.

[0173] The uplink authorization information can include information of multiple different RVs and uplink control information, but is not limited to the information of multiple different RVs and uplink control information. For example, in some embodiments, the uplink authorization information can further include first indication information and / or third indication information. The first indication information is used to indicate that the terminal device sends the content of a same transport block through multiple PUSCHs with different RVs. The third indication information is used to indicate that the multiple different RVs indicated in the uplink authorization information are applied to the transmission of the same transport block.

[0174] It should be noted that in some embodiments, the uplink authorization information referred to in the embodiments of the present disclosure can be transmitted when the received power and / or signal-to-noise ratio of the SRS signal is less than a preset threshold. However, in other embodiments, the transmission condition of the uplink authorization information can not be limited to the received power and / or signal-to-noise ratio of the SRS signal transmitted by the terminal device being less than the preset threshold. In fact, in other embodiments, the transmission condition of the uplink authorization information can be set as needed, such as when the service type of the terminal device is a delay-sensitive service, the uplink authorization information can be transmitted to the terminal device.

[0175] S65, the network device forwards the uplink authorization information to the terminal device.

[0176] By comparing the received power and / or signal-to-noise ratio of the SRS signal with the preset threshold through the network device, and transmitting the comparison result to the base station, the load of the base station can be reduced. When the comparison result is that the received power and / or signal-to-noise ratio is less than the preset threshold, the base station transmits the uplink authorization information to the network device, and the network device forwards the uplink authorization information to the terminal device, so that when the network condition of the terminal device is poor, the terminal device can be instructed in a timely manner to transmit the content of the same transport block through multiple PUSCHs with different RVs, thereby improving the reliability of data transmission.

[0182] S74, when the comparison result is that the received power and / or signal-to-noise ratio is less than the preset threshold, the base station transmits second indication information to the network device.

[0183] Wherein, the second indication information is used to instruct the terminal device to turn on a target function, and the target function includes transmitting the content of the same transport block through multiple PUSCHs with different RVs.

[0184] In some embodiments, the second indication information can be sent to the network device through a media access control layer (MAC) control element (CE) or an RRC configuration parameter. The second indication information can be contained in a reserved field or a custom field of the MAC CE or the RRC configuration parameter.

[0185] It should be noted that, in some embodiments, the second indication information referred to in the embodiments of the present disclosure can be sent when the received power and / or the signal-to-noise ratio of the SRS signal is less than a preset threshold. However, in other embodiments, the sending condition of the second indication information can also not be limited to the received power and / or the signal-to-noise ratio of the SRS signal sent by the terminal device being less than a preset threshold. In fact, in other embodiments, the sending condition of the second indication information can be set as needed, such as when the service type of the terminal device is a delay-sensitive service, the second indication information can be sent to the terminal device.

[0186] S75, the network device forwards the second indication information to the terminal device.

[0187] S76, the base station sends uplink authorization information to the network device.

[0188] S77, the network device forwards the uplink authorization information to the terminal device.

[0189] By comparing the received power and / or the signal-to-noise ratio of the SRS signal with the preset threshold through the network device, and sending the comparison result to the base station, the load of the base station can be reduced. When the comparison result is that the received power and / or the signal-to-noise ratio is less than the preset threshold, the base station sends the second indication information to the network device, and the network device forwards the second indication information to the terminal device, which can timely instruct the terminal device to turn on the function of transmitting the same transport block through multiple PUSCHs with different RVs when the network condition of the terminal device is poor, thereby improving the reliability of data transmission.

However, in other embodiments, the transmission condition of the uplink grant information can not be limited to the received power and / or the signal-to-noise ratio of the SRS signal transmitted by the terminal device being less than the preset threshold. In fact, in other embodiments, the transmission condition of the uplink grant information can be set as needed, for example, when the service type of the terminal device is a delay-sensitive service, the uplink grant information can be transmitted to the terminal device.
