Description

Data processing method and device in multi-connection system

Technical Field

The invention relates to the field of mobile communication, in particular to a data processing method and device in a multi-connection system.

Background

Cellular mobile communications technology has entered the 4G era through a short decades of development, and research into future 5G technology has been undertaken to meet the anticipated future demands for higher, faster, and more up-to-date communications. Currently, the 5G technical goals generally accepted in the industry are: by 2020 or so, a 1000-fold increase in mobile data traffic per region, a 10-to 100-fold increase in throughput per user, a 10-to 100-fold increase in the number of connected devices, a 10-fold increase in battery life for low power devices, and a 5-fold decrease in end-to-end delay are achieved.

The two most significant of the 5G technical goals are to achieve 1-2 orders of magnitude increase in throughput and user peak rate. The industry finds that the 5G technical goal cannot be achieved only by simply enhancing or upgrading the existing network, so that it is necessary to accelerate exploration of aspects such as a novel network deployment strategy and new technology research on the basis of further evolution of the existing network and the existing technology.

In terms of 5G Network deployment strategies, densely deployed networks (UDN, Ultra Relay Network) and using high frequency bands with larger bandwidths (such as 500MHz-1GHz), such as bands above 6GHz, are considered by the industry as two promising approaches in future Network development, wherein densely deployed networks refer to densely deployed low Power nodes (L PN, &lttttranslation = L "&gttl &ltt/t &gtowpower nodes) in indoor and/or outdoor hot spot areas to provide Small cell (Small cell) coverage, conceptually, L PN refers to a base station Node with lower transmission Power than a conventional macro base station and smaller coverage range than that of the conventional macro base station (such as several tens of meters), specifically in existence, may be a micro base station (Pico base station), a home base station (Femto/home) Node, a wireless Relay access device (wireless Relay access Node), and any other base station meeting the concept of the above mentioned concept, and may overcome the existing feature of uniform coverage of the conventional wireless Network, and the future coverage of the high frequency bands, such as the wireless Network, the existing wireless Network, the high frequency coverage of which may not meet the current and wide coverage characteristics of the conventional wireless Network, may overcome the existing indoor and the existing low frequency coverage of the future.

In the research aspect of new technologies, designing a novel physical layer frame (or subframe) structure with shorter subframe length, more flexible uplink and downlink configuration and simpler and faster feedback mechanism, and designing an enhanced communication process on the basis of the novel physical layer frame (or subframe) structure are important directions of 5G new technologies generally accepted in the industry.

The new Technology and the new network topology policy together form a new Radio Access Technology (nRAT) for achieving the 5G technical goal, however, research and commercialization of any Technology are gradually advanced, and it is desired to provide services for a User terminal (UE) by using nRAT in one step, and on one hand, a large amount of long time period technical research work is required to overcome many problems in nRAT independent networking, thereby resulting in serious delays in 5G technical commercialization, and on the other hand, directly abandoning an existing network and deploying a wireless network using nRAT in a large scale will also result in waste of existing investment, so that it is a common consensus in the industry at present that a first stage of 5G (Phase i) deploys a base station (e.g., a macro base station) using nRAT the coverage or coverage boundary of a base station device (e.g., a macro base station) using nRAT (e.g., L PN) to jointly form a Radio Access network for serving the UE, e.g., a base station (e., a macro base station) using 4 g. 2TE (e., TE L, TE) and a UE connected with a long term evolution Technology L connected with the UE.

However, although the L PN using the nRAT achieves low-latency and high-throughput transmission at the bottom layer, such as the physical layer (L), or the physical layer and the Media Access Control (MAC) layer, in the multi-connection system, data delivered from the bottom layer to the upper layer, such as the Radio link Control layer (R L C, io L ink Control) of layer 2, R L C needs to sequence data from different connections to ensure that data delivered to the Protocol layer of the upper layer, such as the Packet data convergence Protocol layer (PDCP, Packet data convergence Protocol) is delivered to the data Packet layer of the upper layer, while data delivered from L TE and data from the nRAT are sequentially different from each other on the rat and the bottom layer, and the sequential data from the rat and the rat are greatly different from each other on the rat and the rat, so that the data packets transmitted at the rat forward data rate and the rat throughput of the rat are greatly reduced by the rat data Packet sequence number before the rat 5G connection, such as the rat data Packet sequence number before the rat 5G data Packet transmission is reduced by the rat 5 TE, which may not be achieved by the rat.

As shown in fig. 6, the protocol architecture diagram is a protocol architecture diagram of a UE side, a MAC layer establishes a logical channel priority function unit L CPFM and a multiplexing function unit mfm, in this embodiment, an RRC or MAC CE indicates that RB1, RB2 and RB3 are divided into two logical channel priority packets, MAC performs logical channel priority grouping according to the indication information of RRC, and divides into 2 packets, 1 st logical channel priority packet and 2 nd logical channel priority packet, 1 st logical channel priority packet handles L CH1 and the priority of MAC CE, 2 nd logical channel priority packet handles L CH2, L CH3 priority, meanwhile, RRC or MAC CE also indicates the mapping relationship between transmission resource information and logical channel priority packets, so that MAC entity realizes transmission of 1 st logical channel priority packet on connection packet 1 (including connection1) when transmission resource information is received, transmission of 2 nd logical channel priority packet 2 (including connection2) on connection packet 2 (including connection2) when transmission resource information and MAC entity indicates that at least one of transmission resource can be realized according to the following types:

the physical layer entities used in this embodiment, connection packet 1 uses physical layer entity PHY-L TE and connection packet 2 uses physical layer entity PHY-nRAT, and the RRC or MAC CE indicates that 1 st logical channel priority packet is mapped to physical layer entity PHY-L TE, i.e. it is equivalent to indicate that 1 st logical channel priority packet is mapped to connection packet 1 (including connection1) and that 2 nd logical channel priority packet is mapped to physical layer entity PHY-nRAT, i.e. it is equivalent to indicate that 2 nd logical channel priority packet is mapped to connection packet 2 (including connection 2).

The RATs used, in this embodiment, connection1 uses L TE and connection2 uses nRAT, and the RRC or MAC CE indicates that the 1 st logical channel priority packet is mapped to the RAT using L TE technology, i.e., it is equivalent to indicating that the 1 st logical channel priority packet is mapped to connection packet 1 (including connection1) and that the 2 nd logical channel priority packet is mapped to the RAT using nRAT, i.e., it is equivalent to indicating that the 2 nd logical channel priority packet is mapped to connection packet 2 (including connection 2).

The connection packet used; the RRC or MAC CE indicates that the 1 st logical channel priority packet is mapped onto connection packet 1 and indicates that the 2 nd logical channel priority packet is mapped onto connection packet 2. Here, the RRC or the MAC CE indicates that the connection packet 1 includes connection1 and the connection packet 2 includes connection 2.

Transmission channels used: in this embodiment, connection1 uses TCH1, and connection2 uses TCH 2; the RRC or MAC CE indicates mapping of the 1 st logical channel priority packet onto TCH1, i.e., equivalent to indicating mapping of the 1 st logical channel priority packet onto connection packet 1 (including connection1), and indicates mapping of the 2 nd logical channel priority packet onto TCH2, i.e., equivalent to indicating mapping of the 2 nd logical channel priority packet onto connection packet 2 (including connection 2).

Network slice used: in this embodiment, connection1 belongs to network slice 1, and connection2 belongs to network slice 2; the RRC or MAC CE indicates mapping of 1 st logical channel priority packet onto the network slice, i.e. is equivalent to indicating mapping of 1 st logical channel priority packet onto connection packet 1 (including connection1), and indicates mapping of 2 nd logical channel priority packet onto network slice 2, i.e. is equivalent to indicating mapping of 2 nd logical channel priority packet onto connection packet 2 (including connection 2).

As can be seen from the above description, the RRC or the MAC CE indicates the mapping relationship between the transmission resource information and the logical channel priority packet, which is equivalent to indicating the mapping relationship between the connection packet and the logical channel priority packet

When the MAC entity receives a transmission resource from a connection1 physical layer entity PHY-L TE or a resource scheduling entity, the MAC entity determines to perform logical channel priority processing on a 1 st logical channel priority packet according to transmission resource information, where the physical layer entity used by the transmission resource received by the MAC entity is a PHY-L TE entity, and thus determines to perform logical channel priority processing on a 1 st logical channel priority packet, or the MAC entity determines that the received transmission resource uses L TE, and thus determines to perform logical channel priority processing on a 1 st logical channel priority packet, or the MAC entity determines that the received transmission resource is from connection1, and thus determines to perform logical channel priority processing on a 1 st logical channel priority packet, or the MAC entity determines that the received transmission resource is from TCH1, and thus determines to perform logical channel priority processing on a 1 st logical channel priority packet, or when the RRC or MAC CE allocates different scheduling identifiers to connection packet 1 and connection packet 2, the MAC entity determines that the transmission resource belongs to a logical channel priority packet of a logical channel priority processing on a 1 st logical channel priority packet, and thus determines that the transmission resource belongs to scheduling of a logical channel priority packet of a logical channel in this logical channel, and a logical channel scheduling resource of a logical channel, where the logical channel priority packet of a logical channel is received connection1 st logical channel, and a logical channel scheduling resource of a logical channel.

L CPFM performs logical channel priority processing on the 1 st logical channel priority packet, and allocates resources indicated in the transmission resources to L CH1 and MAC CE, that is, maps the 1 st logical channel priority packet to the 1 st connection packet, where the 1 st connection packet in this embodiment includes connection1, where the resources indicated in the transmission resources at least include the size of data amount that can be transmitted, such as the number of data bits that can be transmitted, or the number of data bytes that can be transmitted, and specifically allocates the resources indicated in the transmission resources to L CH1 and MAC CE, the processing manner is the same as that in the related art, for example, L TE technology, and the processing procedure is described in the third Generation Partnership Project (3GPP, the 3 Generation Partnership Project) technical specification 36.321, where the processing procedure is summarized here as:

step 1: resources are allocated to all logical channels with Bj >0 (in this embodiment, all logical channels in the 1 st logical channel priority group) according to the priority from high to low. If Bj is set to infinity for a certain logical channel j, then resources are allocated to this logical channel before allocating resources to other lower logical channels to ensure the transmission of all data to be transmitted on this logical channel.

Where Bj is a variable maintained independently for each logical channel, the initial value is set to 0, the value of Bj is incremented by the TTI duration of PRB × for each Transmission Time Interval (TTI), PBR is the Prioritized Bit Rate (Prioritized Bit Rate) of each logical channel, and the value of Bj is the dequeued Size when the value of Bj is incremented to the Bucket Size (Bucket Size) configured for each logical channel.

Step 2: after the allocation in step 1, if the MAC SDU with the size of N bits (bits) is transmitted on the logical channel j, Bj is Bj-N;

and step 3: after the allocation in step 1, if there is a remaining resource indicated in the physical layer transmission scheduling indication, no matter what the value of Bj is, the resource is allocated to each logical channel (also, in this embodiment, the logical channel in the 1 st logical channel priority group) strictly according to the logical channel priority from high to low, that is, when the resource is allocated to one logical channel, if there is a remaining resource after allocating all to-be-transmitted data for sending the logical channel, the resource is continuously allocated to the logical channel of the next priority until all the resources are allocated;

in the above process, it is also necessary to minimize the fragmentation of the data packets (e.g., R L C SDU, retransmitted R L C PDU, etc.), and if necessary, to maximize the use of the resources indicated in the physical layer transmission scheduling indication.

When receiving transmission resources from a connection2 physical layer (PHY-nRAT) or a resource scheduling entity, the mac entity determines to perform logical channel priority processing on the 2 nd logical channel priority packet according to the transmission resource information, where the specific determination method is as described above, L CPFM performs logical channel priority processing on the 2 nd logical channel priority packet, and allocates resources indicated in the transmission resources to L CH2 and L CH3, that is, maps the 2 nd logical channel priority packet to the 2 nd connection packet, where the 2 nd connection packet includes connection 2.

When receiving transmission resources from a connection1 physical layer (PHY-L TE) and a connection2 physical layer (PHY-nRAT), or when receiving transmission resources of connection1 and connection2 from or a resource scheduling entity, the MAC entity determines to perform logical channel priority processing on the 1 st logical channel priority packet and the 2 nd logical channel priority packet according to the transmission resource information, L CPFM performs independent logical channel priority processing on the 1 st logical channel priority packet and the 2 nd logical channel priority packet, i.e., allocates resources indicated in the transmission resources of connection1 to L CH1 and MAC CE, allocates resources indicated in the transmission resources of connection1 to L CH2 and L CH3, i.e., maps the 1 st logical channel priority packet to the 1 st connection packet, and maps the 2 nd logical channel priority packet to the 2 nd connection packet.

After L CPFM allocates resources, the MAC entity notifies the resource allocated to each logical channel to R L C entity corresponding to each logical channel, that is, for L CH1, L CH2, L CH3, R L C entity1, R L4C entity2, R L C entity 3. each R L C entity sends the composed R L C PDU to the MAC entity according to the notified resource allocation size group, and then in this embodiment, the multiplexing function unit (MFM) performs packet multiplexing on R L C PDU on each logical channel priority group, that is, the R L C PDU received from L CH1 and the MAC CE generated by the MAC entity may be grouped into one MAC PDU (in this embodiment, MAC PDU-1), and the R L C PDU received from CH L CH2 and CH 8269556 may be grouped into one MAC PDU (in this embodiment, MAC PDU-862C group).

After the MFM group is completed, the MAC PDU-packet 1 is transmitted on the transport channel TCH1 of connection1 (i.e., connection packet 1), and the MAC PDU-packet 2 is transmitted on the transport channel TCH2 of connection2 (i.e., connection packet 2). That is, the data packet MAC PDU multiplexed in each group of logical channel priority packets is transmitted on the transmission channel included in the connection packet mapped by each group of logical channel priority packets.

It should be noted that, as shown in fig. 6, as the protocol architecture diagram of the UE side corresponds to the base station side, since the base station side needs to process data transmission of multiple UEs simultaneously, the base station side is responsible for processing logical channel priorities of multiple UEs by a unified logical channel priority functional unit, but an independent multiplexing functional unit is set for each UE, taking 2 UEs as an example, and fig. 8 is the protocol architecture diagram of the base station side, in the figure, the logical channel priorities of UE1 and UE2 are both processed in L CPFM, but the MAC PDU multiplexing functions of UE1 and UE2 are respectively processed in an independent MFM.

Through the above processing procedures of this embodiment, the data processing effect as shown in fig. 7 can be achieved, that is, RB1 and MAC CE are transmitted on connection1 after being subjected to logical channel priority processing as one packet, and RB2 and RB3 are transmitted on connection2 after being subjected to logical channel priority processing as one packet, so as to solve the problem that, for one RB, connection1 is encumbered with connection2 due to the difference in data transmission rate between two connections, and the data transmission rate of this RB is finally decreased, and the overall data transmission rate of the UE is finally decreased.

In the same embodiment one, the UE establishes connections with two base stations, i.e. Connection 1(Connection1) and Connection 2(Connection2), and the UE can already transmit uplink and downlink information with the two base stations.

As shown in the protocol architecture diagram of fig. 9, the MAC layer establishes a logical channel priority function L CPFM and two multiplexing functions MFM, MFM1 and MFM 2. similarly, in this embodiment, the RRC or MAC CE instructs to divide RB1, RB2 and RB3 into two logical channel priority packets, the MAC performs logical channel priority grouping into 2 packets according to the instruction information of the RRC, the 1 st logical channel priority packet and the 2 nd logical channel priority packet, the 1 st logical channel priority packet handles the priority of L CH1 and MAC CE, the 2 nd logical channel priority packet handles the priority of L CH2, L CH 3. at the same time, the RRC or MAC CE also instructs the mapping relationship between the transmission resource information and the logical channel priority packets, so that the MAC entity, upon receiving the transmission resource information, implements the transmission of the 1 st logical channel priority packet over the connection packet 1 (including connection1), the transmission of the 2 nd logical channel priority packet over the connection2 (including connection2) and the connection information from the MAC layer when receiving the connection resource information and the connection specification of the transmission resource from the RRC-MAC CE L.

L after the CPFM has allocated the resources, the MAC entity notifies the resources allocated to each logical channel to the R L C entity corresponding to each logical channel, that is, for L0 CH1, L CH2, L CH L, respectively to R L C entity L, R L4 center L, R L5C entity 3. each R L C entity allocates a size group according to the notified resource, sends the composed R L C PDU to the MAC entity, and then in this embodiment, the multiplexing functional unit 1(MFM L) performs packet multiplexing on the R L C PDU on the 1 st logical channel priority packet, that is, the R L C PDU received from L CH L is unified with the MAC CE group generated by the MAC entity, and can be grouped in one MAC PDU (denoted as MAC PDU-packet-1) after the CPFM has allocated the resources, the multiplexing functional unit 2(m L) performs mapping on the first MAC PDU (i.e., the MAC PDU is mapped to the first logical channel PDU), so that the MAC PDU is connected to the MAC PDU (i.e., the MAC PDU is connected to the MAC PDU) L C PDU, so that the MAC PDU is connected to the MAC PDU, the MAC PDU connected to the MAC PDU of the MAC PDU (L C PDU, and the MAC PDU after the MAC PDU is mapped to the MAC PDU, the MAC PDU is mapped to the MAC PDU, so that the MAC PDU connected to the MAC PDU of the MAC PDU, the MAC packet connected to the MAC packet connected PDU connected to the MAC packet of the MAC packet (L PDU, and the MAC packet of the MAC packet L PDU, the MAC packet of the MAC.

Fig. 9 is a protocol architecture diagram of a UE side, corresponding to a base station side, where the base station side is to process data transmission of multiple UEs at the same time, and the base station side is responsible for processing logical channel priorities of multiple UEs by a unified logical channel priority functional unit, but an independent multiplexing functional unit is set for each UE, and assuming that each UE establishes two connections as shown in fig. 9 in this embodiment, the base station side sets two independent MFMs (MFM1 and MFM2) for each UE. Through the above processing procedure of the present embodiment, the data processing effect as shown in fig. 7 can be also achieved.
