[0023] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0024] The term "plurality" in the embodiments of the present disclosure refers to two or more than two, and other quantifiers are similar thereto.

[0025] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] In the related art, a shared memory method is usually used to realize data interaction between the cells corresponding to the RLC layer and the MAC layer. However, the shared memory method cannot meet the cross-board data movement requirements. Therefore, in the process of data interaction between the cells corresponding to the RLC layer and the MAC layer, if the carrier of the primary cell MAC and the carrier of the secondary cell MAC are located on different boards, it will have a greater impact on the carrier aggregation effect, thereby affecting the data transmission rate of the uplink communication link and the downlink communication link.

[0027] The present disclosure is intended to solve the above-mentioned technical problems existing in the related art, and provides a carrier aggregation method. Since it does not rely on a shared memory method to realize data interaction between the cells corresponding to the RLC layer and the MAC layer, it can effectively solve the above-mentioned technical problems existing in the related art, and can effectively realize cross-board carrier aggregation when the carrier provided by the primary cell MAC and the carrier provided by the secondary cell MAC are located on different boards, thereby effectively improving the carrier aggregation effect and effectively assisting in improving the data transmission rate of the uplink communication link and the downlink communication link.

A wireless terminal device may communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a radio access network.

Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, and user devices, which are not limited in the embodiments of the present disclosure.

[0037] like Figure 1 As shown, the carrier aggregation method includes:

[0038] S101: Receive a carrier aggregation request transmitted by a primary cell MAC, wherein the carrier aggregation request is used to aggregate a first carrier and a second carrier when transmitting data to be transmitted, the first carrier corresponds to a first board to which the primary cell MAC belongs, and the second carrier corresponds to a second board to which the secondary cell MAC belongs.

[0039] Among them, the media access control layer (Media Access Control, MAC) corresponding to the primary cell can be called the primary cell MAC, and correspondingly, the media access control layer MAC corresponding to the secondary cell can be called the secondary cell MAC. The primary cell and the secondary cell can be determined according to the terminal device identifier carried in the activation message when the activation message sent by the terminal device is received, and there is no restriction on this.

[0040] The execution subject of this embodiment may specifically be a radio link layer control protocol RLC cell corresponding to the primary cell MAC. The RLC cell may correspond to the same board as the primary cell MAC, and the board may be referred to as a first board.

[0041] The carrier aggregation request may be transmitted from the primary cell MAC to the RLC cell, and the carrier aggregation request is used to trigger the RLC cell to aggregate the carrier resources of the primary cell MAC and the secondary cell MAC.

[0042] The carrier aggregation request may also be specifically triggered by a Packet Data Convergence Protocol (PDCP), and there is no limitation on this.

[0043] Among them, the carrier provided by the first board card to which the main cell MAC belongs can be called the first carrier, and the carrier provided by the second board card to which the secondary cell MAC belongs can be called the second carrier. When transmitting the data to be transmitted, the data to be transmitted can be modulated onto the first carrier and the second carrier to transmit the data to be transmitted.

[0044] In the embodiment of the present disclosure, when receiving a carrier aggregation request transmitted by the primary cell MAC, the secondary cell MAC corresponding to the primary cell MAC can be determined, and the second board to which the secondary cell MAC belongs can be determined. The primary cell MAC and the secondary cell MAC correspond to different boards. The first board and the second board can be different boards in the same frame, or can be boards in different frames, and there is no limitation on this.

[0045] S102: Determine the set data volume of the radio link layer control protocol RLC cell corresponding to the primary cell MAC.

[0046] When receiving the carrier aggregation request transmitted by the primary cell MAC, the secondary cell MAC corresponding to the primary cell MAC can be determined, and after determining the second board to which the secondary cell MAC belongs, the set data volume of the radio link layer control protocol RLC cell corresponding to the primary cell MAC can be determined.

[0047] The set data volume may specifically be a buffer occupancy (BO) data volume. The set data volume may be used to describe the size of the data volume to be moved to the second board. The set data volume may specifically be determined by a packet data convergence protocol PDCP.

[0048] When the Packet Data Convergence Protocol PDCP decides to obtain a set data volume, the decision may be made specifically based on data service requirements, and there is no limitation to this.

[0049] That is to say, when determining the set data volume of the radio link layer control protocol RLC cell corresponding to the primary cell MAC, the set data volume correspondingly transmitted by the packet data convergence protocol PDCP may be directly received.

[0050] S103: Transmitting a portion of the data to be transmitted with a set amount of data to the second board.

[0051] When receiving the carrier aggregation request transmitted by the main cell MAC, the secondary cell MAC corresponding to the main cell MAC can be determined, and the second board to which the secondary cell MAC belongs can be determined. After determining the set data volume of the wireless link layer control protocol RLC cell corresponding to the main cell MAC, part of the set data volume in the data to be transmitted can be transmitted to the second board, thereby assisting in the subsequent modulation of part of the data to the second carrier corresponding to the second board, so as to transmit the part of the data via the second carrier.

[0052] In some embodiments, if the first board and the second board may be different boards in the same frame, part of the data may be directly transferred from the first board to the second board based on the number of the second board; if the first board and the second board are boards in different frames, the frame number of the second board may be determined, and part of the data may be transferred from the first board to the second board based on the frame number combined with the number of the second board. There is no limitation on this.

[0053] In the disclosed embodiment, part of the data with a set amount of data in the data to be transmitted is transmitted to the second board card, which can be specifically implemented by moving data, that is, moving part of the data with a set amount of data in the data to be transmitted to the second board card, rather than copying data, thereby effectively avoiding the impact of data copying on data transmission performance and effectively improving data transmission performance.

[0054] After transmitting a set amount of part of the data to be transmitted to the second board, the first carrier can be used to transmit the remaining data, and the second carrier can be used to transmit part of the data, wherein the remaining data and part of the data together constitute the data to be transmitted, thereby realizing efficient carrier aggregation and effectively improving the data transmission rate of the uplink communication link and the downlink communication link.

[0055] Part of the data to be transmitted with a set data volume is moved to the second board, and the data other than the part of the data to be transmitted can be called remaining data.

[0056] When the remaining data is transmitted using the first carrier and part of the data is transmitted using the second carrier, the remaining data can be modulated onto the first carrier and part of the data can be modulated onto the second carrier to transmit the data to be transmitted in the form of aggregating the first carrier and the second carrier.

[0057] In this embodiment, by receiving a carrier aggregation request transmitted by the main cell MAC, wherein the carrier aggregation request is used to aggregate the first carrier and the second carrier when transmitting the data to be transmitted, the first carrier corresponds to the first board to which the main cell MAC belongs, and the second carrier corresponds to the second board to which the secondary cell MAC belongs, and the set data volume of the wireless link layer control protocol RLC cell corresponding to the main cell MAC is determined, and part of the set data volume in the data to be transmitted is transmitted to the second board. When the carrier provided by the main cell MAC and the carrier provided by the secondary cell MAC are located on different boards respectively, carrier aggregation across boards can be effectively realized, thereby effectively improving the carrier aggregation effect, and effectively assisting in improving the data transmission rate of the uplink communication link and the downlink communication link.

[0058] Figure 2 It is a flowchart of a carrier aggregation method proposed in another embodiment of the present disclosure.

[0059] like Figure 2 As shown, the carrier aggregation method includes:

[0060] S201: receiving an activation message, where the activation message includes: a terminal device identifier.

[0061] Among them, the message currently used to activate the primary cell or the secondary cell can be called an activation message.

[0062] For example, the RLC cell receives an activation message MSG_MACRLC_Ca_StatusInd sent by the primary cell MAC or the secondary cell MAC. The activation message MSG_MACRLC_Ca_StatusInd may carry a terminal device identifier. When the primary cell or the secondary cell is activated according to the activation message, a primary cell and / or a secondary cell is generated accordingly.

[0063] S202: Determine a cell topology relationship, which describes a topology relationship among multiple candidate primary cell MACs, candidate secondary cell MACs corresponding to the candidate primary cell MACs, and candidate RLC cells corresponding to the candidate primary cell MACs.

[0064] After receiving the activation message, the cell topology relationship may be determined. The cell topology relationship may be generated in advance based on the carrier aggregation (CA) relationship cell addition message O_RRCMAC_NR_CELL_INFO_IND triggered.

[0065] For example, when the main cell MAC receives the carrier aggregation CA relationship cell addition message O_RRCMAC_NR_CELL_INFO_IND, it can trigger the generation of a cell topology relationship. The cell topology relationship describes the topological relationship between multiple candidate main cell MACs, the candidate secondary cell MACs corresponding to the candidate main cell MACs, and the candidate RLC cells corresponding to the candidate main cell MACs. Then, the main cell MAC can send a handshake message O_MACRLC_CA_HAND_IND to the corresponding RLC cell based on the cell relationship, so that the RLC cell records the cell topology relationship. Subsequently, the cell topology relationship can be used to assist in distinguishing buffer occupancy (Buffer Occupation, BO), high-end memory addresses for storing data (the high-end memory address can be referred to as the subsequent target address, and the description of the target address can be specifically referred to in the subsequent embodiments), etc., and with the subsequent access of terminal devices, the activation of the main cell MAC and the secondary cell MAC is triggered.

[0066] S203: Determine a primary cell MAC from multiple candidate primary cell MACs according to the terminal device identifier.

[0067] S204: The candidate secondary cell MAC corresponding to the primary cell MAC is used as the secondary cell MAC, and the candidate RLC cell corresponding to the primary cell MAC is used as the RLC cell.

[0068] After receiving the activation message and determining the cell topology relationship, the main cell MAC can be determined from multiple candidate main cell MACs according to the terminal device identifier carried by the activation message, and the candidate secondary cell MAC corresponding to the main cell MAC can be used as the secondary cell MAC, and the candidate RLC cell corresponding to the main cell MAC can be used as the RLC cell, so that the main cell MAC, the secondary cell MAC, and the corresponding RLC cell can be quickly determined based on the cell topology relationship, and the first board and the second board that need to perform the data moving task can be quickly determined, thereby assisting in the accurate implementation of subsequent data moving functions.

[0069] S205: Receive a target address transmitted by the primary cell MAC, where the target address indicates a data storage address in the second board to which the secondary cell MAC belongs.

[0070] After determining the primary cell MAC, secondary cell MAC, and corresponding RLC cell, the target address transmitted by the primary cell MAC can be received together. The target address can be used to indicate the high-end memory address of the data stored in the second board. The high-end memory address can be specifically, for example, the BO high-end memory address.

[0071] For example, the RLC cell reports the BO data volume (ie, the set data volume) occupied by the buffer according to the BO high-end memory address allocated by the MAC, and reports the BO data volume occupied by the buffer to the main cell MAC.

[0072] S206: Determine, according to the target address, a first data amount corresponding to the primary cell MAC and a second data amount corresponding to the secondary cell MAC.

[0073] After receiving the target address transmitted by the primary cell MAC, the first data amount corresponding to the primary cell MAC and the second data amount corresponding to the secondary cell MAC may be determined according to the target address.

[0074] The amount of data that needs to be allocated to the primary cell MAC may be referred to as a first amount of data, and correspondingly, the amount of data that needs to be allocated to the secondary cell MAC may be referred to as a second amount of data.

[0075] In the disclosed embodiment, the allocation ratio can be pre-set via the primary cell MAC, and then, referring to the allocation ratio in combination with the target address, the amount of data that needs to be allocated to the primary cell MAC is determined as the first data amount, and then the amount of data that needs to be allocated to the secondary cell MAC is determined as the second data amount, without any restriction.

[0076] S207: Receive a carrier aggregation request transmitted by the primary cell MAC, wherein the carrier aggregation request is used to aggregate a first carrier and a second carrier when transmitting data to be transmitted, the first carrier corresponds to a first board to which the primary cell MAC belongs, and the second carrier corresponds to a second board to which the secondary cell MAC belongs.

[0077] S208: Determine a set data volume of the RLC cell corresponding to the first board according to the first data volume and the second data volume.

[0078] S209: Transmitting a portion of the data to be transmitted with a set data volume to the second board.

[0079] The description of S207-S209 can be specifically referred to the above embodiment, which will not be repeated here.

[0080] In some embodiments, when transferring a set amount of data in the data to be transmitted to the second board card, it can be specifically when receiving the secondary cell scheduling message transmitted by the main cell MAC, performing a data moving task for part of the data involved in the RLC cell, so as to transfer part of the data to the second board card of the opposite end, thereby completing the data movement of cross-board carrier aggregation CA.

[0081] like Figure 3 As shown, Figure 3It is a schematic diagram of the RLC and MAC interaction process of cross-board CA in the embodiment of the present disclosure. Among them, the main cell board Slot1 to which the main cell MAC belongs can be called the first board, and the secondary cell board Slot2 to which the secondary cell MAC belongs can be called the second board. The main cell board Slot1 provides the first carrier (carrier 1) via the port physical layer (Physical Layer, PHY), and the secondary cell board Slot2 port physical layer PHY provides the second carrier (carrier 2). The carrier aggregation CA relationship cell addition message O_RRCMAC_NR_CELL_INFO_IND can be generated by the high layer (High Layer, HL).

[0082] S210: Report the first remaining data of the first data volume to the primary cell MAC.

[0083] S211: Report second remaining data of a second data volume to the secondary cell MAC, wherein the first remaining data and the second remaining data together constitute the remaining data.

[0084] For example, when the RLC cell reports the BO data volume (i.e., the set data volume) occupied by the buffer according to the BO high-end memory address assigned by the MAC, and reports the BO data volume occupied by the buffer to the main cell MAC, the first data volume of the main cell MAC and the second data volume of the secondary cell MAC can also be reported to the main cell MAC together. Then, the main cell MAC allocates the corresponding proportion of the remaining data (the corresponding proportion of the remaining data determined by referring to the first data volume can be called the first remaining data) to itself with reference to the first data volume, allocates the corresponding proportion of the remaining data (the corresponding proportion of the remaining data determined by referring to the second data volume can be called the second remaining data) to the secondary cell MAC with reference to the second data volume, and transmits part of the data of the set data volume to the second board card, that is, allocates part of the data to the secondary cell MAC, and the second board card corresponding to the secondary cell MAC undertakes the forwarding processing logic of the part of the data volume, thereby realizing the migration of cross-board data.

[0085] S212: Use the first carrier to transmit the first remaining data, and use the second carrier to transmit the partial data and the second remaining data.

[0086] In some embodiments, when the remaining data is transmitted using the first carrier and partial data is transmitted using the second carrier, the first remaining data can also be modulated to the first carrier, and the partial data and the second remaining data can be modulated to the second carrier to transmit the data to be transmitted in the form of aggregating the first carrier and the second carrier, and there is no limitation on this.

[0087] In this embodiment, when the carrier provided by the primary cell MAC and the carrier provided by the secondary cell MAC are located in different boards, carrier aggregation across boards can be effectively realized, thereby effectively improving the carrier aggregation effect and effectively assisting in improving the data transmission rate of the uplink communication link and the downlink communication link. After receiving the activation message and determining the cell topology relationship, the primary cell MAC can be determined from multiple candidate primary cell MACs according to the terminal device identifier carried by the activation message, and the candidate secondary cell MAC corresponding to the primary cell MAC can be used as the secondary cell MAC, and the candidate RLC cell corresponding to the primary cell MAC can be used as the RLC cell, so that the primary cell MAC, the secondary cell MAC, and the corresponding RLC cell can be quickly determined based on the cell topology relationship, and the first board and the second board that need to perform the data transfer task can be assisted in quickly determining, and the subsequent data transfer function can be accurately implemented.

[0088] Figure 4 It is a flowchart of a carrier aggregation method proposed in another embodiment of the present disclosure.

[0089] like Figure 4 As shown, the carrier aggregation method includes:

[0090] S401: Receive a carrier aggregation request transmitted by a primary cell MAC, wherein the carrier aggregation request is used to aggregate a first carrier and a second carrier when transmitting data to be transmitted, the first carrier corresponds to a first board to which the primary cell MAC belongs, and the second carrier corresponds to a second board to which the secondary cell MAC belongs.

[0091] S402: Determine the set data volume of the radio link layer control protocol RLC cell corresponding to the primary cell MAC.

[0092] The description of S401 - S402 can be specifically referred to the above embodiment, which will not be repeated here.

[0093] In this embodiment, the data moving function provided by the driver board is called to move a set amount of data in the data to be transmitted to the second board as an example. The data moving function can be specifically exemplified by a Block Transmission Over Ethernet (BTOE) interface function, and there is no limitation to this.

[0094] The functions of the Block Transmit Over Ethernet (BTOE) interface can be illustrated as follows:

[0095] See also above Figure 3As shown, the target address of data transfer indicated by the primary cell MAC and the data source address corresponding to the RLC cell, wherein the target address indicated by the primary cell MAC is notified to the RLC cell through process (b), with a total of 5 time slot addresses, which are used to fill the address field specified by the Ethernet block transmission BTOE interface; the data source address involved in the RLC cell is divided into two types, the data plane development tool set (Date Plane Development Kit, DPDK) memory and the high-end memory, both of which meet the requirement of continuous physical address transfer, the data source address of the RLC, the DPDK memory address stores the content including: data, status report, header information, PAD field in the Ethernet frame, the high-end memory address is used to store the data feedback information sent by the RLC to the MAC, the data source address can be applied by the MAC and notified to the RLC in process (b), and there are also 5 different addresses in the time slots.

[0096] like Figure 5 As shown, Figure 5 It is a schematic diagram of the structure of the data source address in the embodiment of the present disclosure.

[0097] S403: Receive source data information transmitted by the primary cell MAC.

[0098] The source data information may be a data source address and data length information, thereby assisting in quickly reading the data to be transmitted.

[0099] S404: Identify part of the data to be transmitted based on the source data information and the set data volume.

[0100] In the disclosed embodiment, it is possible to avoid copying the data to be transmitted to the RLC cell. Instead, the data source address is directly provided to the RLC cell. The RLC cell can directly read the data to be transmitted based on the data source address, and identify part of the data from the data to be transmitted in combination with the data length information and the set data volume determined above, thereby effectively avoiding the copying of the data content in the storage module corresponding to the RLC cell, thereby saving time for cross-board data forwarding performance and effectively improving the efficiency of cross-board data forwarding.

[0101] S405: Acquire an initial address field corresponding to the initial data transfer interface, where the initial data transfer interface is used to transfer the data from the interface to the data storage address indicated by the field value of the initial address field.

[0102] The initial data transfer interface may be a Block Transmission Over Ethernet (BTOE) interface provided by the aforementioned driver network card, and the Block Transmission Over Ethernet (BTOE) interface has a corresponding initial address field.

[0103] S406: Configure the target address to a field value corresponding to the initial address field to obtain a target data transfer interface.

[0104] After obtaining the initial address field corresponding to the initial data transfer interface, the target address sent by the primary cell MAC may be configured as the field value corresponding to the initial address field, thereby using the configured Block Transmission Over Ethernet (BTOE) interface as the target data transfer interface.

[0105] S407: According to the partial data, the target data transfer interface is called to transfer the partial data of the set data volume in the data to be transmitted to the second board.

[0106] In the embodiment of the present disclosure, the above Figure 5 As shown, when calling the target data transfer interface to perform the data transfer task, the source data block can be Figure 5 Fill the structure shown in the figure with data and set the target address as above. Figure 5 The format shown in is filled into the initial address field of the Ethernet block transport BTOE interface.

[0107] Therefore, since the initial address field corresponding to the initial data moving interface is obtained, the initial data moving interface is used to move the data of the incoming interface to the data storage address indicated by the field value of the initial address field, and the target address is configured as the field value corresponding to the initial address field, so as to obtain the target data moving interface, and according to partial data, the target data moving interface is called to transmit part of the data with a set amount of data to be transmitted to the second board card, which can effectively meet the carrier aggregation scenario where the time division duplex mode and the frequency division duplex mode do not share the same board. When performing the data moving task, only the address needs to be operated, thereby effectively avoiding data copying, effectively reducing the packet assembly delay caused by data copying, and greatly improving the data forwarding performance of cross-board carrier aggregation CA.

[0108] With respect to the carrier aggregation method described in the above embodiment, Figure 6 As shown, Figure 6 It is a schematic diagram of the carrier aggregation principle in the embodiment of the present disclosure, and the carrier aggregation CA includes: a BO maintenance module and a data processing module, a CA relationship maintenance module, wherein the update of the carrier aggregation CA relationship (i.e., the cell topology relationship) depends on the notification of MAC, the storage cell belongs to the frame, maintains the relationship mapping between the main cell and the secondary cell, notifies the RLC of the packet address of the secondary cell, and the data storage address of the above-mentioned partial data (which can be understood as BO data), whether the secondary cell MAC transmits partial data (BO data) can be decided by whether the secondary user is downlink activated or whether there is data service, and the MAC executes the BO data volume decision. Figure 6In the data processing module, when maintaining the CA relationship, the data source address is pre-allocated by the MAC. In the actual carrier aggregation process, corresponding scheduling can be performed according to the scheduling service needs of the primary and secondary cells. The primary scheduling and the shared-board secondary scheduling are processed according to the original packet assembly process, and the data are stored in the original shared memory. The packet assembly process of the cross-board carrier aggregation CA can fill the target address into the BTOE data movement interface provided by the driver board to execute the movement of part of the data and transmit part of the data to the board where the secondary cell MAC is located (ie, the second board).

[0109] In this embodiment, when the carrier provided by the primary cell MAC and the carrier provided by the secondary cell MAC are located on different boards, carrier aggregation across boards can be effectively realized, thereby effectively improving the carrier aggregation effect and effectively assisting in improving the data transmission rate of the uplink communication link and the downlink communication link. By directly providing the data source address to the RLC cell, the RLC cell can directly read the data to be transmitted based on the data source address, and identify part of the data from the data to be transmitted in combination with the data length information and the set data volume determined above, thereby effectively avoiding the copy of the data content in the storage module corresponding to the RLC cell, thereby saving time for cross-board data forwarding performance and effectively improving the efficiency of cross-board data forwarding. It can effectively meet the carrier aggregation scenario where the time division duplex mode and the frequency division duplex mode do not share the same board. When performing the data migration task, only the address needs to be operated, thereby effectively avoiding the copy of the data, effectively reducing the packet delay caused by the data copy, and significantly improving the data forwarding performance of the cross-board carrier aggregation CA.
