[0036] The technical solutions in the present disclosure will be described clearly and completely below with reference to the drawings in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0037] It should be noted that in the present disclosure, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design scheme described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or having more advantages than other embodiments or design schemes. In fact, the use of the words "exemplary" or "for example" is intended to present related concepts in a manner of illustration only.

[0038] Hereinafter, the terms "first", "second", and the like are used only for the purpose of description, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0039] In the description of the disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" herein is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "multiple" means two or more.

[0040] It can be understood that, without conflict, the functions, steps, etc. shown in the disclosure can occur in an order different from that shown in the disclosure, and there can be other functions, steps, etc. between any two adjacent functions, steps, etc. shown in the disclosure.

[0041] With the improvement of communication technology and the continuous enrichment of service types, related services have higher requirements for the performance of communication, such as holographic communication, XR and other services requiring communication performance to simultaneously meet ultra-high throughput and ultra-low latency. Such services combine the characteristics of two scenarios of enhanced mobile broadband (eMBB) and ultra-reliable and low latency communication (URLLC), not only having very high requirements for throughput, but also having very high requirements for latency. For future-oriented communication systems, the application of artificial intelligence (AI), perception and big data will also bring the demand for large data volume information transmission.

[0042] In wireless communication, physical layer scheduling transmission is usually performed through transport blocks (TBs). Each TB is mapped to an antenna for transmission after channel coding, modulation and other physical layer operations. When the size of the TB (TBS) is too large, the probability of transmission failure will also increase accordingly, resulting in low data transmission reliability.

[0043] Exemplarily, as shown in FIG. 1, for each codeword, each hybrid automatic repeat request (HARQ) process only processes one TB in one transmission time interval (TTI), and each TB is mapped to an antenna for transmission after channel coding, modulation and other physical layer operations.

[0044] Each TB has a cyclic redundancy check (CRC), and if the TB forms multiple coding blocks (CBs) after channel coding, each CB also has a CRC. Only when the CRCs of all CBs and the CRC of the entire TB pass the check, the TB can be successfully acquired and submitted to the media access control (MAC) layer. When the size (TBS) of the TB is too large, any CRC check failure will cause the entire TB transmission to fail, seriously affecting the reliability of data transmission.

[0045] In view of this, in the technical solutions provided in the present disclosure, the first network element can obtain a transmission pattern and configure the transmission pattern for a TB set. Then, the first network element can send multiple TBs in the TB set to the second network element on a physical channel based on the configured transmission pattern. The transmission pattern is used to indicate each transmission of a TB set. When the size of the TB is too large, it will cause the success rate of data transmission to be low, seriously affecting the reliability of data transmission. The way that the first network element in the present disclosure implements multiple TB transmissions based on the transmission pattern can guarantee the reliability of data transmission. When there is a TB that fails to transmit in the multiple TBs, the TB that fails to transmit does not affect other TBs that successfully transmit in the multiple TBs. For example, the TBs corresponding to the upper layer data in the TBs that successfully transmit (the data of the TBs comes from the upper layer, i.e., the first type of TB) can be independently submitted to the upper layer at the receiving end. And according to the transmission pattern, the TBs that successfully transmit can be used to recover the TBs that fail to transmit through packet encoding and decoding, further improving the reliability of data transmission. At the same time, the present disclosure can also implement static or semi-static scheduling control of the TB set based on the transmission pattern, thereby avoiding frequent signaling interaction in the transmission process and reducing the complexity of scheduling and control signaling overhead.

[0046] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) in the embodiments of the present disclosure can at least include a first network element and a second network element. It should be understood that in the present example, the first network element can be a network side device (including but not limited to a base station, for example), and the second network element can be a terminal side device (including but not limited to a terminal, for example). Of course, in the uplink, the first network element can also be a terminal side device, and the second network element can also be a network side device. In addition, the first network element and the second network element can also be a module of a device in a communication system, or a protocol layer (including but not limited to a MAC layer, for example) in a communication system. The module can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0047] Exemplarily, as shown in FIG. 2, a communication system provided by an embodiment of the present disclosure includes a base station 201 and a terminal 202. The base station 201 and the terminal 202 can be one or more, and the number is not limited.

[0048] The base station 201 is located at the access network side of the above communication system, and is a device with a wireless transceiving function or a chip or chip system that can be arranged in the device. The base station 201 includes but is not limited to: an access point (AP) in a WiFi system, such as a home gateway, a router, a server, a switch, a bridge, and the like; an evolved NodeB (eNB); a radio network controller (RNC); a NodeB (NB); a base station controller (BSC); a base transceiver station (BTS); a home base station (for example, a home evolved NodeB, or a home NodeB, HNB); a baseband unit (BBU); a wireless relay node; a wireless backhaul node (for example, an integrated access and backhaul (IAB) node); a transmission and reception point (transmission and reception point, TRP, or transmission point, TP); and the like, and can also be a 5G base station, such as a gNB in a new radio (NR) system, or a transmission point (TRP or TP), one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU), a road side unit (RSU) with a base station function, or a 5G access network (NG radio access network, NG-Ran) device, and the like. The base station 201 also includes base stations in different networking modes, such as a master evolved NodeB (MeNB), a secondary eNB (SeNB, or secondary gNB, SgNB). The base station 201 also includes different types, such as ground base stations, air base stations, and satellite base stations, and the like.

[0049] The terminal 202 is a device with wireless communication function, which can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted. It can also be deployed on water surface (such as ships, etc.), and can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal 202 is also called user equipment (UE), mobile station (MS), mobile terminal (MT) and terminal device, which is a device providing voice and / or data connectivity to users. For example, the terminal 202 includes handheld devices with wireless connection function, vehicle-mounted devices, etc. At present, the terminal 202 can be: mobile phone, tablet computer, notebook computer, palm computer, mobile internet device (MID), wearable device (such as smart watch, smart bracelet, pedometer, etc.), vehicle-mounted device (such as car, bicycle, electric vehicle, airplane, ship, train, high-speed rail, etc.), virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, smart home device (such as refrigerator, television, air conditioner, electric meter, etc.), smart robot, workshop device, wireless terminal in self driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, flight device (such as smart robot, hot air balloon, unmanned aerial vehicle, airplane), etc. In an exemplary application scenario of the present disclosure, the terminal is a terminal that usually works on the ground, such as a vehicle-mounted device. In the present disclosure, in order to facilitate description, a chip deployed in the above device, such as a system on a chip (SOC), a baseband chip or other chips with communication function can also be referred to as a terminal.

[0050] In some embodiments, for downlink transmission, the base station 201 can obtain a transmission pattern and configure the transmission pattern to a set of TBs to be transmitted. Then, the base station 201 can transmit a plurality of TBs in the set of TBs on a physical channel based on the configured transmission pattern. Correspondingly, the terminal 202 can obtain the transmission pattern and configure the transmission pattern to the set of TBs. Then, the terminal 202 can receive a plurality of TBs in the set of TBs from the base station 201 on a physical channel based on the configured transmission pattern. Generally, the transmission pattern is determined by the base station 201 before the transmission of the set of TBs, and the transmission pattern is sent to the terminal 202 by using a radio resource control (RRC) message (e.g., an RRC reconfiguration message) so that the base station 201 and the terminal 202 perform the transmission of the set of TBs based on the same transmission pattern.

[0051] In some embodiments, for uplink transmission, the terminal 202 can obtain a transmission pattern and configure the transmission pattern to a set of TBs. Then, the terminal 202 can transmit a plurality of TBs in the set of TBs on a physical channel based on the configured transmission pattern. Correspondingly, the base station 201 can obtain the transmission pattern and configure the transmission pattern to the set of TBs. Then, the base station 201 can receive a plurality of TBs in the set of TBs from the terminal 202 on a physical channel based on the configured transmission pattern. Generally, the transmission pattern is determined by the base station 201 before the transmission of the set of TBs, and the transmission pattern is sent to the terminal 202 by using an RRC message (e.g., an RRC reconfiguration message) so that the base station 201 and the terminal 202 perform the transmission of the set of TBs based on the same transmission pattern.

[0052] The plurality of TBs can include TB original packets for carrying upper layer data, and can also include TB redundancy packets (also referred to as TB check packets) for error recovery of the TB original packets.

[0053] In some embodiments, the base station 201 or the terminal 202 can generate TB redundancy packets (also referred to as TB check packets) for error recovery of TB original packets by packet encoding. Packet encoding, also known as network encoding, is a technology for improving network throughput and data reliability. Generally, this encoding technology is referred to as network encoding. Since it is encoding of multiple independent data packets, network encoding is also referred to as packet encoding. The present disclosure does not distinguish between them. Packet encoding aims to integrate data before transmission, and the receiving end can recover the data based on the integration method.

[0054] The encoding type of the packet encoding includes linear packet encoding and nonlinear packet encoding. Taking the linear packet encoding as an example, a new transmission block TB3 (which can also be referred to as a TB redundancy packet or a TB check packet) can be obtained by performing an AND operation on the transmission blocks TB1 and TB2 (which can also be referred to as a TB original packet, a TB source packet, or a TB system packet). The sending end sends the three transmission blocks, and the receiving end can recover another failed transmission block (such as recovering TB2 by means of TB1 and TB3, or recovering TB1 by means of TB2 and TB3) as long as any two transmission blocks are successfully received.

[0055] Exemplarily, the encoding algorithm used by the packet encoding can be a fountain code. The fountain code has the characteristics that the code rate can be unlimitedly sent, and the receiving end can recover all original packets with a large probability as long as a sufficient amount of packet encoding packets are received. For example, for k TB original packets to be transmitted, k+m encoded TBs (including k TB original packets and m TB check packets) are obtained after packet encoding, and the receiving end can recover all TB original packets with a target probability as long as any k TBs in the k+m encoded TBs are successfully received.

[0056] It should be noted that the embodiments of the disclosure can be mutually referenced or referred to each other, for example, the same or similar steps, method embodiments, system embodiments, and device embodiments can be mutually referred to, and are not limited.

[0057] The communication method provided by the embodiments of the disclosure will be described below by taking the interaction between the first network element and the second network element as an example in the communication system shown in FIG. 2. It should be noted that in the embodiments of the disclosure described below, the first network element is the sending end of the data, and the second network element is the receiving end of the data. The first network element and the second network element can be devices in the communication system, modules of the devices, or protocol layers in the communication system. The disclosure is illustrated by taking the first network element and the second network element as the execution subject of the interaction as an example, but the disclosure does not limit the execution subject of the interaction.

[0058] FIG. 3 is a flowchart of a communication method according to an embodiment of the disclosure. As shown in FIG. 3, the method includes the following S301 to S303:

[0059] S301, obtaining a transmission pattern.

[0060] The transmission pattern is used to indicate each transmission of a TB set.

[0061] In some embodiments, the TB set includes a plurality of first type TBs and / or one or more second type TBs.

[0062] In one example, the TB set includes k first type TBs, each of the k first type TBs corresponding to one upper layer protocol data unit (PDU), k being an integer greater than 1. For example, the upper layer PDU can be a MAC PDU.

[0063] In one example, the TB set further includes at least one second type TB, the at least one second type TB being obtained by packet encoding the k first type TBs, each of the at least one second type TB being a TB check packet after packet encoding; the TB check packet being used for error recovery of the TB original packet.

[0064] For example, one TB set can include only a plurality of first type TBs. For another example, one TB set can include a plurality of first type TBs and at least one second type TB. For another example, one TB set can include only a plurality of second type TBs.

[0065] Exemplarily, the TB set can also be referred to as a TB group (TBG). The TB original packet before packet encoding is also referred to as a TB system packet or a TB source packet, which is data transmitted from an upper layer to a physical layer at a sending end or data that needs to be delivered to an upper layer by a physical layer at a receiving end. Each first type TB corresponds to one MAC PDU. The TB system packet or the TB source packet after packet encoding is the same as the TB original packet before packet encoding.

[0066] The TB check packet is also referred to as a TB redundancy packet, which is a TB encoding packet after packet encoding. In some packet encoding algorithms, the TB check packet contains part of information of the first type TB after multiplication operation in a finite field. The data of the TB check packet is data generated at a physical layer, which is used for error recovery of the TB original packet, and the receiving end does not need to deliver the TB check packet to an upper layer. At the receiving end, the TB check packet can be used for decoding recovery of the failed TB original packet. Each TB check packet needs a corresponding encoding matrix vector in the decoding of packet encoding.

[0067] In one implementation, the first network element obtains the transmission pattern through an RRC signaling message.

[0068] Exemplarily, the RRC signaling message includes an index number of the transmission pattern, the index number of the transmission pattern being used for indicating the transmission pattern. Using the index of the transmission pattern can greatly reduce the control signaling overhead of delivering the transmission pattern related information (such as configuration parameters and transmission strategy). For example, the first network element locally stores a transmission pattern index mapping table, and the first network element can determine the configuration parameters and / or the transmission strategy corresponding to the TB set transmission through the transmission pattern index.

[0069] In one example, the first network element can receive an RRC reconfiguration message to obtain a transmission pattern, which includes a transmission pattern field.

[0070] S302, Configure the transmission pattern for the TB collection.

[0071] In one example, the first network element configures the transmission pattern via RRC signaling messages. For instance, the RRC reconfiguration message includes fields for the transmission pattern. Based on the transmission pattern, the first network element configures the transmission parameters (the configuration parameters mentioned above) and / or transmission strategies for the TB set transmission.

[0072] The first network element configures the data transmission of a TB set according to the transmission parameters and / or transmission strategy indicated by the transmission pattern. In one example, according to the transmission pattern, the TB set needs to be transmitted four times. Each transmission sends a different redundancy version (RV) for the same TB, but the transmission resources, modulation and coding scheme (MCS), and number of spatial multiplexing layers used in each transmission are the same. In this way, the second network element can directly perform soft information merging on the different RVs of each received TB to obtain soft merging gain, thereby improving the TB transmission success rate.

[0073] S303. Based on the configured transmission pattern, send multiple TBs from the TB set to the second network element on a physical channel.

[0074] In one implementation, the first network element sends multiple TBs to the second network element over a single transmission unit.

[0075] The transmission unit includes at least one of the following: TTI, slot, minislot, and HARQ process.

[0076] For example, for downlink transmission, the physical channel can be a downlink data transmission channel, such as a physical downlink shared channel (PDSCH). In this case, multiple TBs are carried on a single PDSCH and transmitted using a single transmission unit.

[0077] For uplink transmission, the physical channel can be an uplink data transmission channel, such as a physical uplink shared channel (PUSCH). In this case, multiple TBs are transmitted on a single PUSCH using a single transmission unit.

[0078] In one implementation, multiple TBs are mapped to the same codeword and sent to the second network element.

[0079] Based on the above technical solution, the first network element can obtain a transmission pattern and configure the transmission pattern for the TB set. Then, the first network element can send multiple TBs in the TB set to the second network element on a physical channel based on the configured transmission pattern. The transmission pattern is used to indicate each transmission of a TB set. When the size of the TB is too large, it will cause the success rate of data transmission to be low, which seriously affects the reliability of data transmission. The way of the first network element in the present disclosure to implement multiple TB transmission per transmission based on the transmission pattern can guarantee the reliability of data transmission. When there is a transmission failure TB in the multiple TBs, the transmission failure TB does not affect other transmission success TBs in the multiple TBs. For example, the TB corresponding to the upper layer data in the transmission success TB (the data of the TB corresponding to the upper layer data comes from the upper layer, i.e., the first type of TB) can be independently submitted to the upper layer at the receiving end. And according to the transmission pattern, the transmission success TB can be used to recover the transmission failure TB through packet encoding and decoding, further improving the reliability of data transmission. At the same time, the present disclosure can also implement static or semi-static scheduling control of the TB set based on the transmission pattern, thereby avoiding frequent signaling interaction in the transmission process and reducing the complexity of scheduling and control signaling overhead.

[0080] In some embodiments, before S303, the first network element can further perform at least one of the following: determining the size of the first type of TB; determining the number of the first type of TB; determining the number of the second type of TB; selecting the TB to be sent in each transmission of the TB set; determining the RV of the TB to be sent in each transmission of the TB set; determining the transmission resource space used in each transmission of the TB set; determining the transmission resource used by each TB in each transmission of the TB set; determining the MCS used in each transmission of the TB set; determining the spatial multiplexing mode used in each transmission of the TB set; determining the HARQ process identifier in each transmission of the TB set; and determining the period of TB transmission of the TB set.

[0081] The first type of TB is the TB original packet in the TB set, and the second type of TB is the TB check packet obtained by packet encoding all TB original packets in the TB set. The transmission resource includes one of the following: time domain resource, frequency domain resource, and time-frequency domain resource.

[0082] Exemplarily, for each TB transmitted in each transmission of the selected TB set, the first network element can select the TBs for transmission in the order of the TB serial numbers (in ascending order or in descending order) for each TB set. For example, for a TB set including k first type TBs and m second type TBs, the serial numbers of the first type TBs are 0 to k-1, and the serial numbers of the second type TBs are k to k+m-1. The first network element can transmit the TBs in order, so that the second network element can also calculate the serial numbers of each second type TB according to the scheme, and then determine the packet encoding vector corresponding to the received second type TB, so as to facilitate the decoding of the subsequent packet encoding.

[0083] For determining the transmission resource space used by each transmission of the TB set, the first network element can implement by at least one of the following: taking the transmission resource position of the TB successfully transmitted last time as the transmission resource position of the second type TB in the current transmission; using a fixed transmission resource position for each transmission of the TB set; using a fixed transmission resource position for each transmission of each TB.

[0084] In some embodiments, the transmission pattern can correspond to different transmission strategies, so as to realize flexible configuration of the TB set.

[0085] In some embodiments, the transmission pattern can correspond to at least one of the following: a first transmission strategy, a second transmission strategy, a set of transmission parameters.

[0086] As an embodiment of the present disclosure, the transmission pattern corresponds to a first transmission strategy of the TB set; the first transmission strategy includes but is not limited to one of the following:

[0087] All first type TBs in the TB set are transmitted in each transmission;

[0088] All first type TBs in the TB set are transmitted in the first transmission of the TB set, and at least one first type TB and at least one second type TB in the TB set are transmitted in the retransmission of the TB set;

[0089] All first type TBs in the TB set are transmitted in the first transmission of the TB set, and the same number of second type TBs as the first transmission in the TB set are transmitted in the retransmission of the TB set;

[0090] A certain number of second type TBs in the TB set are transmitted at a fixed transmission resource position in each transmission.

[0091] That is, the above first transmission strategy is used to indicate the transmission manner of the TB set. The first network element can perform data transmission of a TB set according to the above first transmission strategy corresponding to the transmission pattern.

[0092] As another embodiment of the present disclosure, the transmission pattern corresponds to a second transmission strategy of the TB set; the second transmission strategy includes but is not limited to one of the following:

[0093] selecting one RV for each TB in each transmission according to a fixed RV order;

[0094] selecting the TB for each transmission from the TB set according to the TB sequence number.

[0095] That is, the second transmission strategy described above is used to indicate the transmission mode of each TB in the TB set. For example, the fixed RV order can be "RV0, RV2, RV3, RV1". For TB0 in the TB set that needs to be transmitted, the first network element can send the redundancy version RV0 of TB0 in the first transmission, the redundancy version RV2 of TB0 in the second transmission, the redundancy version RV3 of TB0 in the third transmission, and the redundancy version RV1 of TB0 in the fourth transmission.

[0096] In some embodiments, when the TB fails in the first transmission, retransmission is needed to improve the success rate of reception. After channel coding of a TB, a plurality of redundancy versions of the TB can be obtained by selecting certain data at different starting positions of the channel coded data. The sender sends different RVs each time, and the receiver can combine different RVs to improve the success rate of data transmission.

[0097] In some embodiments, the transmission pattern can correspond to one or more transmission parameters (a set of transmission parameters described above), so as to configure the scheduling of the TB set.

[0098] As an embodiment of the present disclosure, the transmission pattern corresponds to one or more transmission parameters, and the transmission parameters include at least one of the following:

[0099] a TB set identifier of the TB set;

[0100] a number of resource elements (REs) used by the TB set in each transmission;

[0101] a transmission resource space used by the TB set in each transmission;

[0102] a common MCS used by the TB set in each transmission, the common MCS being used to indicate that the TBs in the TB set are transmitted using the same MCS;

[0103] a common spatial multiplexing manner used by the TB set in each transmission, the common spatial multiplexing manner being used to indicate that the TBs in the TB set are transmitted using the same spatial multiplexing manner;

[0104] a number of TBs in the TB set each time of transmission;

[0105] a number of TBs in the TB set each time of transmission;

[0106] a size of a first type of TB in the TB set each time of transmission;

[0107] a number of the first type of TB in the TB set each time of transmission;

[0108] a number of a second type of TB in the TB set each time of transmission;

[0109] a packet encoding vector index corresponding to the second type of TB in the TB set each time of transmission;

[0110] a serial number of each TB in the TB set each time of transmission;

[0111] an RV of each TB in the TB set each time of transmission;

[0112] a HARQ process identity in the TB set each time of transmission;

[0113] a transmission period of the TB set, the transmission period being used for periodic transmission of the TB set.

[0114] The transmission resource space refers to transmission resources available for TB transmission in the TB set. The transmission resources include one of the following: time domain resources, frequency domain resources, and time-frequency domain resources. The first type of TB is a TB original packet in the TB set, and the second type of TB is a TB check packet obtained by packet encoding all TB original packets in the TB set.

[0115] The total size of a TB set can be determined by the transmission resource space corresponding to the TB set, the MCS, and the number of layers of spatial multiplexing mapping. For example, the total size of the TB set corresponds to the sum of sizes of all first type of TBs in the TB set. For example, the total size of the TB set corresponds to the total number of TB bits that can be transmitted by the entire TB set, which can be regarded as a virtual large TB. Since directly transmitting large TB data can easily cause TB errors, the total size of the TB set can be used for segmentation to obtain multiple small TBs (i.e., first type of TBs) in the present disclosure, and the multiple TBs obtained by segmentation are transmitted as a TB set. That is, the virtual large TB is not a real TB, which is only described for ease of understanding.

[0116] Exemplarily, the packet encoding vector of the TB can be indicated by a packet encoding vector index, or can be implicitly indicated by being associated with the sequence number of the TB. That is, the packet encoding vector corresponding to the TB can be determined by the sequence number of the TB. The type of the TB can be indicated by type indication information, or can be indicated by the sequence number of the TB. For example, one TB set includes k first-type TBs and m second-type TBs, and the sequence numbers of the first-type TBs can be arranged in front, for example, the TBs with sequence numbers ranging from 0 to k-1 are first-type TBs, and the TBs with sequence numbers ranging from k to k+m-1 are second-type TBs.

[0117] FIG. 4 is a flowchart of a communication method according to an embodiment of the present disclosure. As shown in FIG. 4, the method includes the following S401 to S403:

[0118] S401, obtaining a transmission pattern.

[0119] The transmission pattern is used to indicate each transmission of a TB set.

[0120] In some embodiments, the TB set includes a plurality of first-type TBs and / or one or more second-type TBs.

[0121] In one example, the TB set includes k first-type TBs, each of the k first-type TBs corresponding to one upper-layer PDU, and k is an integer greater than 1. For example, the upper-layer PDU can be a MAC PDU.

[0122] In one example, the TB set further includes at least one second-type TB, the at least one second-type TB being obtained by packet encoding the k first-type TBs, the first-type TB being a TB original packet before packet encoding, and each of the at least one second-type TB being a TB check packet after packet encoding; the TB check packet is used for error recovery of the TB original packet.

[0123] In one implementation, the second network element obtains the transmission pattern through an RRC signaling message.

[0124] Exemplarily, the RRC signaling message includes an index number of the transmission pattern, and the index number of the transmission pattern is used to indicate the transmission pattern. Using the transmission pattern index can greatly reduce the control signaling overhead of transmitting transmission pattern related information (such as configuration parameters and transmission strategies).

[0125] In one example, the second network element can receive an RRC reconfiguration message to obtain the transmission pattern, and the RRC reconfiguration message includes a transmission pattern field.

[0126] The related description can refer to S301 described above, which will not be repeated here.

[0127] S402, configure a transmission pattern for the TB set.

[0128] In one example, the second network element configures the transmission pattern through an RRC signaling message. For example, a field of the transmission pattern is included in an RRC reconfiguration message. Based on the transmission pattern, the second network element configures transmission parameters (configuration parameters) and / or transmission strategies for the TB set transmission.

[0129] The related description can refer to S302 described above, and will not be repeated here.

[0130] S403, receive multiple TBs in the TB set from the first network element on one physical channel based on the configured transmission pattern.

[0131] In one implementation, the second network element receives multiple TBs in the TB set from the first network element on one transmission unit.

[0132] The transmission unit includes at least one of the following: TTI, time slot, micro time slot, and HARQ process.

[0133] In some embodiments, the multiple TBs are mapped to the same code word.

[0134] The related description can refer to S303 described above, and will not be repeated here.

[0135] In some embodiments, before S403 described above, the second network element can further perform at least one of the following: determine the size of the first type of TB; determine the number of the first type of TB; determine the number of the second type of TB; determine the transmission resource space used by the TB set for each transmission; determine the transmission resource used by each TB of the TB set for each transmission; determine the MCS used by the TB set for each transmission; determine the spatial multiplexing manner used by the TB set for each transmission; determine the period of TB transmission of the TB set; determine the HARQ process identity for each transmission of the TB set; determine the type of the received TB; determine the TB sent by the TB set for each transmission; determine the RV of the TB sent by the TB set for each transmission; combine multiple RVs of the same TB received; determine the TB serial number of the received second type of TB; determine the packet encoding vector of the received second type of TB; perform channel decoding on the received first type of TB to successfully obtain the first type of TB; perform channel decoding on the received second type of TB to successfully obtain the second type of TB; and perform packet encoding decoding using the successfully obtained second type of TB and the successfully obtained first type of TB to recover the first type of TB that has not been successfully obtained.

[0136] The type of TB includes one of the following: a first type of TB or a second type of TB. The first type of TB is a TB original packet in the TB set, and the second type of TB is a TB check packet obtained by packet encoding all TB original packets in the TB set. The transmission resource includes one of the following: a time domain resource, a frequency domain resource, and a time-frequency domain resource.

[0137] Exemplarily, for determining the transmission resource space used by the TB set for each transmission, the second network element can implement by at least one of the following: taking the transmission resource position of the TB successfully transmitted last time as the transmission resource position of the second type of TB for this time; using a fixed transmission resource position for each transmission of the TB set; and using a fixed transmission resource position for each transmission of each TB.

[0138] For determining the TB serial number of the received second type of TB, the second network element can calculate the serial number of each received TB according to the rule that the TB serial number is transmitted from small to large based on the transmission pattern.

[0139] In some embodiments, according to the transmission pattern, the second network element can acquire TB data of the TB set at the corresponding transmission resource position and perform channel decoding of the TB. According to the transmission pattern, the second network element can also perform soft information merging on different RV versions of the same TB. According to the transmission pattern, the second network element can first process the reception of the first type of TB, and if there is a first type of TB that fails to be acquired (i.e., fails to be received), the second network element then processes the reception of the second type of TB. According to the transmission pattern, the second network element can also perform packet encoding decoding on the successfully received second type of TB to recover the first type of TB that fails to be transmitted.

[0140] Channel encoding / decoding refers to encoding / decoding of data in a TB. For example, at the sending end, a 100-bit TB is subjected to 1 / 3 code rate channel encoding to form a 300-bit encoded packet sent to a modulation module. At the receiving end, the demodulated data information is subjected to channel decoding to recover 100-bit TB source bit information.

[0141] Packet encoding / decoding refers to encoding / decoding between multiple TB data packets. For example, at the sending end, four 100-bit first type of TBs are subjected to packet encoding to generate six 100-bit second type of TBs. At the receiving end, if the four first type of TBs are not all successfully acquired, the successfully acquired second type of TBs and all successfully acquired first type of TBs are jointly subjected to packet encoding and corresponding decoding to recover the first type of TBs that fail to be transmitted.

[0142] In some embodiments, the transmission pattern can correspond to at least one of the following: a first transmission strategy, a second transmission strategy, and a set of transmission parameters.

[0143] In some embodiments, the transmission pattern can correspond to different transmission strategies, thereby achieving flexible configuration of the TB set.

[0144] As an embodiment of the present disclosure, the transmission pattern corresponds to a first transmission strategy of the TB set; the first transmission strategy includes but is not limited to one of the following:

[0145] All first type TBs in the TB set are transmitted each time;

[0146] All first type TBs in the TB set are transmitted at the first transmission of the TB set, and at least one first type TB and at least one second type TB in the TB set are transmitted at the retransmission of the TB set;

[0147] All first type TBs in the TB set are transmitted at the first transmission of the TB set, and the same number of second type TBs as the first transmission in the TB set are transmitted at the retransmission of the TB set;

[0148] A certain number of second type TBs in the TB set are transmitted at a fixed transmission resource location each time.

[0149] That is, the above-mentioned first transmission strategy is used to indicate the transmission manner of the TB set. The second network element can perform data reception of a TB set according to the above-mentioned first transmission strategy corresponding to the transmission pattern.

[0150] As another embodiment of the present disclosure, the transmission pattern corresponds to a second transmission strategy of the TB set; the second transmission strategy includes but is not limited to one of the following:

[0151] An RV is selected for each TB each time according to a fixed RV order;

[0152] TBs for each transmission are selected from the TB set in turn according to TB serial numbers.

[0153] That is, the above-mentioned second transmission strategy is used to indicate the transmission manner of each TB in the TB set.

[0154] In some embodiments, the transmission pattern can correspond to one or more transmission parameters (a set of transmission parameters mentioned above), thereby achieving configuration of the scheduling of the TB set.

[0155] As an embodiment of the present disclosure, the transmission pattern corresponds to one or more transmission parameters, and the transmission parameters include at least one of the following:

[0156] TB set identifier of the TB set;

[0157] Number of REs used by the TB set each time;

[0158] Transmission resource space used by the TB set each time;

[0159] a common MCS used by the TB set for each transmission, the common MCS being used to indicate that the TBs in the TB set are transmitted using a same MCS;

[0160] a common spatial multiplexing manner used by the TB set for each transmission, the common spatial multiplexing manner being used to indicate that the TBs in the TB set are transmitted using a same spatial multiplexing manner;

[0161] a transmission resource used by each TB in the TB set for each transmission;

[0162] a number of TBs in the TB set for each transmission;

[0163] a size of the first type of TBs in the TB set for each transmission;

[0164] a number of the first type of TBs in the TB set for each transmission;

[0165] a number of the second type of TBs in the TB set for each transmission;

[0166] a packet encoding vector index corresponding to the second type of TBs in the TB set for each transmission;

[0167] a sequence number of each TB in the TB set for each transmission;

[0168] an RV of each TB in the TB set for each transmission;

[0169] an HARQ process identity for each transmission of the TB set;

[0170] a transmission period of the TB set, the transmission period being used for periodic transmission of the TB set.

[0171] The transmission resource space refers to a transmission resource available for transmission of the TBs in the TB set. The transmission resource includes one of the following: a time domain resource, a frequency domain resource, and a time-frequency domain resource. The first type of TBs are original packets of the TBs in the TB set, and the second type of TBs are TB check packets obtained by packet encoding all the original packets of the TBs in the TB set.

[0172] It should be understood that the communication method provided in the present disclosure can be applied to various TB transmission scenarios, for example, can be applied to various transmission pattern acquisition manners, can be applied to configuration of various transmission patterns, and can be applied to various communication scenarios.

[0173] For various transmission pattern acquisition manners, in an example, taking a first network element as a terminal and a second network element as a base station as an example, the terminal can receive an RRC control signaling message carrying a transmission pattern of a TB set from the base station, and transmit the TBs in the TB set in each transmission of the TB set according to the transmission pattern of the TB set.

[0174] In one example, the first network element is a base station, and the second network element is a terminal. The terminal can receive an RRC control signaling message carrying a transmission pattern of a TB set from the base station, and receive the TBs in each transmission of the TB set according to the transmission pattern of the TB set.

[0175] In one example, the RRC control signaling message is an RRC reconfiguration message, and the RRC reconfiguration message carries a transmission pattern index. Through the transmission pattern index, a transmission pattern can be obtained.

[0176] In one example, there can be multiple TB sets in the transmission of the TB set. Each TB set uses the same transmission pattern for TB transmission.

[0177] For the configuration of multiple transmission patterns, the receiving end can perform soft information combination by sending different RV versions of a TB in each transmission. In the present disclosure, multiple TBs are transmitted in each transmission of a TB set, and each TB in the TB set can also be transmitted using different RV versions. That is, each first type TB has a different RV, and each second type TB also has a different RV.

[0178] In one example, the redundancy version (RV) of each TB is selected in the order of “RV0, RV3, RV2, RV1”. The TB can transmit RV0 in the first transmission, and can transmit other redundancy versions (RVs) in the retransmission.

[0179] In some embodiments, the TB set is semi-statically configured with a transmission pattern through an RRC control signaling message. There can be multiple patterns in the communication system, and the RRC control signaling message indicates which transmission pattern in the multiple patterns is used. The transmission pattern implicitly indicates the transmission strategy of the TB set.

[0180] Exemplarily, there are multiple transmission patterns (patterns) in the communication system, and the base station selects a pattern to configure to the terminal through an RRC signaling message for the transmission and / or reception of the TB set. The following are five transmission patterns as examples:

[0181] Pattern 1: Each transmission of a first type TB, and the RV selection rule is that the first type TB selects different redundancy versions (RVs) in the order of RV0, RV2, RV3, and RV1.

[0182] An example of Pattern 1 is shown in FIG. 5. There are 4 first type TBs (TB0, TB1, TB2, TB3) in a TB set, and each TB uses the same transmission resource to transmit a different RV of the TB in each transmission. In the first transmission, the first network element transmits RV0 of TB0, TB1, TB2, TB3. In the first retransmission (i.e., the second transmission of the TB set), the first network element transmits RV2 of TB0, TB1, TB2, TB3. In the second retransmission (i.e., the third transmission of the TB set), the first network element transmits RV3 of TB0, TB1, TB2, TB3. In the third retransmission (i.e., the fourth transmission of the TB set), the first network element transmits RV1 of TB0, TB1, TB2, TB3.

[0183] Pattern 2: Transmit k first type TBs in the first transmission, and transmit m different RVs of the first type TBs and n different RVs of the second type TBs in the retransmission. The RV selection rule is that the first type TBs and the second type TBs are sequentially selected as RV0, RV2, RV3, RV1. In the retransmission, a new second type TB is replaced into the position of a certain TB in the last transmission according to a certain rule.

[0184] An example of Pattern 2 is shown in FIG. 6. There are 4 first type TBs (TB0, TB1, TB2, TB3) in a TB set, and 4 first type TBs are packet encoded to generate multiple second type TBs (TB4, TB5, TB6). In the first transmission, the first network element transmits RV0 of TB0, TB1, TB2, TB3. In each retransmission, a certain first type TB in the last transmission is replaced with the RV0 of a new second type TB in the order of TB serial number. The RV selection rule is that the RVs are sequentially selected as RV0, RV2, RV3, RV1. For example, in the first retransmission (i.e., the second transmission of the TB set), the first network element transmits RV2 of TB1, TB2, TB3 and RV0 of TB4. In the second retransmission (i.e., the third transmission of the TB set), the first network element transmits RV3 of TB2, TB3, RV2 of TB4 and RV0 of TB5. In the third retransmission (i.e., the fourth transmission of the TB set), the first network element transmits RV1 of TB3, RV3 of TB4, RV2 of TB5 and RV0 of TB6. The second type TBs can help the receiving end to recover the failed first type TBs, and the use of new second type TBs to replace the previously transmitted first type TBs can reduce the impact of certain interference on the first type TBs. The TBs with different RVs can enable soft combining gain in the TB retransmission, and improve the transmission success rate of the TBs.

[0185] Pattern 3: The first transmission of k first type TBs, and the retransmission of k second type TBs with different redundancy versions (RVs).

[0186] An example of Pattern 3 is shown in FIG. 7. There are 4 first type TBs (TB0, TB1, TB2, TB3) in a TB set, and the 4 first type TBs are packet encoded to generate multiple second type TBs (TB4, TB5, TB6, TB7). At the first transmission, the first network element transmits RV0 of TB0, TB1, TB2, TB3. At each retransmission, the second type TBs are transmitted, and the RV selection rule is that the second type TBs are selected in the order of RV0, RV2, RV3, RV1 to use different redundancy versions (RVs) for transmission. For example, at the first retransmission (i.e., the second transmission of the TB set), the first network element transmits RV0 of TB4, TB5, TB6, TB7. At the second retransmission (i.e., the third transmission of the TB set), the first network element transmits RV2 of TB4, TB5, TB6, TB7. At the third retransmission (i.e., the fourth transmission of the TB set), the first network element transmits RV3 of TB4, TB5, TB6, TB7. The second type TBs can help the receiving end to recover the first type TBs that fail to be transmitted, and the second type TBs with different RVs can enable soft combining gain for the retransmission of the second type TBs, thereby improving the transmission success rate of the second type TBs.

[0187] Pattern 4: The first transmission of k first type TBs, and the retransmission of only k second type TBs with RV0.

[0188] An example of Pattern 4 is shown in FIG. 8. There are 4 first type TBs (TB0, TB1, TB2, TB3) in a TB set, and the 4 first type TBs are packet encoded to generate multiple second type TBs (TB4, TB5, TB6, TB7, TB8, TB9, TB10, TB11, TB12, TB13, TB14, TB15). At the first transmission, the first network element transmits RV0 of TB0, TB1, TB2, TB3. At each retransmission, RV0 of new second type TBs is transmitted. For example, at the first retransmission (i.e., the second transmission of the TB set), the first network element transmits RV0 of TB4, TB5, TB6, TB7. At the second retransmission (i.e., the third transmission of the TB set), the first network element transmits RV0 of TB8, TB9, TB10, TB11. At the third retransmission (i.e., the fourth transmission of the TB set), the first network element transmits RV0 of TB12, TB13, TB14, TB15. The second type TBs can help the receiving end to recover the first type TBs that fail to be transmitted. The transmission of new second type TBs at each retransmission can improve the transmission success rate of the second type TBs.

[0189] Pattern 5: At least one second type TB is transmitted per transmission.

[0190] An example of Pattern 5 is shown in FIG. 9. There are 4 first type TBs (TB0, TB1, TB2, TB3) in a TB set, and 4 first type TBs are packet encoded to generate at least one second type TB (e.g., TB4). A certain number of second type TBs are transmitted in a fixed position per transmission. The RV selection rule is that both first type TBs and second type TBs are selected in the order of RV0, RV2, RV3, RV1 to transmit different redundancy versions (RVs). At the first transmission, the first network element transmits RV0 of TB0, TB1, TB2, TB3, and TB4. At the first retransmission (i.e., the second transmission of the TB set), the first network element transmits RV2 of TB0, TB1, TB2, TB3, and TB4. At the second retransmission (i.e., the third transmission of the TB set), the first network element transmits RV3 of TB0, TB1, TB2, TB3, and TB4. At the third retransmission (i.e., the fourth transmission of the TB set), the first network element transmits RV1 of TB0, TB1, TB2, TB3, and TB4. The second type TBs can help the receiving end to recover the first type TBs that fail to be successfully acquired. If there are first type TBs that are not successfully acquired when received by the receiving end, the receiving end can perform channel decoding on the second type TBs, and then perform packet decoding according to the TBs that are successfully acquired to recover the first type TBs that are not successfully acquired.

[0191] It can be understood that the above transmission patterns are only used for example and illustration. The transmission patterns used in the wireless communication system can not be limited to the above patterns, and can not correspond to the above transmission pattern examples.

[0192] In some embodiments, the transmission pattern includes a configuration of a series of parameters. For example, using the transmission pattern can determine the parameter values of the fixed transmission resource position, MCS, number of spatial multiplexing layers, etc. for the TB set transmission.

[0193] For example, after the MAC layer obtains the transmission pattern through RRC, the MAC layer performs scheduling of the TB set. The MAC layer maps the TBs of the TB set to a physical channel (such as PDSCH or PUSCH) using the parameters and transmission strategies corresponding to the transmission pattern.

[0194] In some embodiments, different RV versions of multiple TBs of a TB set can be transmitted by the transmission pattern indication. In this way, multiple TBs can be sent on one time slot, and soft information combining can be performed on multiple RV versions of the same TB on multiple time slots, improving the success rate of TB transmission, and thus improving the reliability of the service and the throughput of data transmission. The transmission pattern indication of the TB set indicates different RV versions of the TB transmitted each time, so that the receiving end improves the transmission success rate of a single TB by soft information combining.

[0195] In some embodiments, TB check packets (second type of TB) generated by packet encoding of TB original packets (first type of TB) of a TB set can be transmitted by the transmission pattern indication. In this way, error recovery of TB original packets can be performed by TB check packets. Since TB original packets are TBs carrying upper layer data, using multiple TB transmission of a TB set and transmitting TB check packets can improve the transmission success rate of TB original packets, and thus improve the reliability of the service and the throughput of data transmission. The transmission pattern indication of the TB set indicates the sending of the second type of TB, which can help the receiving end to recover the first type of TB that fails to transmit, and improve the transmission success rate of the entire TB set.

[0196] In one example, if the second type of TB is sent, the second type of TB is sent according to certain rules, so that the receiving end can know the packet encoding vector used by the second type of TB according to the rules to perform packet decoding. For example, the second type of TB is sent in the order of TB serial number, and the receiving end calculates the serial number of the TB according to the transmission pattern, and then calculates the packet encoding vector used by the second type of TB.

[0197] For various communication scenarios, taking the high reliability scenario as an example, holographic communication, XR, AI model transmission, and large data transmission applications bring high reliability transmission requirements for large data. When the TB size (TBS) is large, the entire TB will fail to transmit when a certain segment of data is disturbed and cannot be recovered. A large TB contains a lot of data, and if the transmission fails, it will have serious consequences. Especially for edge users, due to poor performance caused by coverage, the above problems will be more serious.

[0198] The efficiency of data transmission of a large TB transmitted in one TTI is low. This is because using a large TB for transmission will occupy a large bandwidth, and there is different degree of frequency selectivity on each subcarrier of the allocated bandwidth. In order to ensure normal transmission, the worst subband of the channel condition needs to be used as the main basis for scheduling MCS level selection, which will result in low data transmission efficiency. Even so, when a certain segment of bandwidth has a burst disturbance, the entire TB will fail to decode successfully due to this disturbance.

[0199] The present disclosure uses TB set transmission, so the TB set is no longer limited to the worst channel condition within the allocated bandwidth, but can use a better MCS. For example, if only one TB is transmitted on a larger transmission resource space, the TB is limited to frequency selective fading and can only be transmitted using a lower MCS. This makes the TB size (TBS) not large, and the amount of upper layer data that can be carried is not large. Even so, when strong interference occurs in a certain transmission resource, the TB can be retransmitted, but since one TB occupies the entire large transmission resource space, the likelihood of the TB failing is still high. When the maximum number of retransmissions is reached and the TB is still not successfully transmitted, it will be discarded, which will cause a large consumption of transmission resources and a decrease in data reliability. The method of using the TB set transmission of the present disclosure divides the transmission resource space of the original large TB into multiple TBs of a TB set, and each TB of the TB set can be transmitted using a larger MCS. On the same transmission resource space, the larger the MCS, the larger the amount of TB data that can be carried. This makes the sum of the TBS of all first type TBs greater than the TBS of transmitting only one TB on the transmission resource space, i.e., the TB set transmission can carry more upper layer data transmission. Moreover, even if a first type TB fails due to frequency selective fading or interference, the TB check packet can be used to recover the failed TB, which improves the likelihood that all first type TBs are successfully transmitted in a short period of time. It can be seen that the use of the present disclosure can improve data transmission efficiency and data reliability.

[0200] However, if a large data packet is divided into multiple small TBs of a TB set for dynamic transmission, it may bring complexity to scheduling transmission, such as the scheduling and control of multiple TBs being more complex, such as the need to increase control signaling overhead, etc. In the present disclosure, only the fixed TB set transmission pattern needs to be configured by RRC (such as using the RRC reconfiguration message), and the transmission is achieved by a static fixed transmission method to meet the reliability requirements, thereby reducing the scheduling complexity and reducing the control signaling overhead.

[0201] In summary, the technical solution provided by the present disclosure can ensure data transmission reliability while having low signaling overhead and simple transmission, achieving efficient transmission of high-reliability services.

[0202] It can be understood that the communication device comprises a hardware structure and / or a software module corresponding to each function in order to realize the above functions. Those skilled in the art should easily realize that the algorithm steps of each example described in combination with the embodiments of the present disclosure can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is realized in the form of hardware or computer software driven hardware depends on the specific application of the technical solution and the design constraint conditions. The skilled person can use different methods to realize the described functions for each specific application, but such implementation should not be considered beyond the scope of the present disclosure.

[0203] The embodiments of the present disclosure can divide the function modules of the communication device according to the above method embodiments. For example, each function module can be divided according to each function, or two or more functions can be integrated into one function module. The above integrated module can be realized in the form of hardware or software. It should be noted that the division of the modules in the embodiments of the present disclosure is illustrative, and is only a logical function division. In actual implementation, another division method can be used. The following will be described taking the division of each function module according to each function as an example.

[0204] For example, taking the communication device as the first network element in the above method embodiments, FIG. 10 is a structure diagram of a first network element 100 according to an embodiment of the present disclosure. The first network element 100 can execute the communication method provided by the above method embodiments. As shown in FIG. 10, the first network element 100 comprises a processing unit 1001 and a communication unit 1002.

[0205] The processing unit 1001 is configured to obtain a transmission pattern, the transmission pattern being used to indicate each transmission of a set of transport blocks TBs.

[0206] The processing unit 1001 is configured to configure the set of TBs with the transmission pattern.

[0207] The communication unit 1002 is configured to transmit a plurality of TBs in the set of TBs to a second network element on a physical channel based on the configured transmission pattern.

[0208] In some embodiments, the set of TBs comprises k first type TBs, each of the k first type TBs corresponding to an upper layer protocol data unit PDU, and k is an integer greater than 1.

[0209] In some embodiments, the set of TBs further comprises at least one second type TB, the at least one second type TB being obtained by packet encoding the k first type TBs, the first type TB being a TB original packet before packet encoding, and each of the at least one second type TB being a TB check packet after packet encoding; the TB check packet being used for error recovery of the TB original packet.

[0210] In some embodiments, the transmission pattern corresponds to at least one of the following: the first transmission strategy, the second transmission strategy, a set of transmission parameters (one or more transmission parameters).

[0211] In some embodiments, the transmission pattern corresponds to the first transmission strategy of the TB set; the first transmission strategy includes but is not limited to one of the following:

[0212] All first type TBs in the TB set are transmitted each time;

[0213] All first type TBs in the TB set are transmitted at the first transmission of the TB set, and at least one first type TB and at least one second type TB in the TB set are transmitted at the retransmission of the TB set;
