Detailed ways

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

For the data duplication transmission scheme in the related art, it should be noted that, for the CA architecture, referring to FIG. 1 , the data technology provides a data duplication transmission under the CA architecture. Protocol structure, as can be seen from Figure 1, the PDCP layer replicates the configured duplication according to the PCDP Service Data Unit (SDU) configuration data, so that the original PDCP PDU and the duplicated PDCP PDU (Duplicated PDCP PDU) can be obtained, followed by PDCP. The PDU passes through the Radio Link Control (RLC) entity (RLC Entity) A, and the Duplicated PDCP PDU enters the Medium Access Control (MAC) layer through the RLC Entity B, and then the PDCP PDU is Duplicated PDCP PDUs are set to transmit on different physical carriers.

For the DC architecture, the serving cell group provided by the station provided by the primary base station MeNB is referred to as a primary cell group (MCG), and the serving cell group provided by the secondary base station SeNB is referred to as a secondary cell group (SCG, Secondary Cell). Group). The cell group (CG, Cell Group) in which the PDCP layer is located is called an anchor CG. Therefore, the anchor CG is usually an MCG. 2 and FIG. 3, which shows a protocol structure for data duplication transmission under DC architecture provided by the related art. Taking FIG. 2 as an example, the PDCP layer of the anchor CG (CG1) will be the PDCP protocol. The data unit (PDU, Protocol Data Unit) is copied into the same two copies, one of which is the original PDCP PDU and the other is the duplicate Duplicated PDCP PDU. The original PDCP PDU passes through the RLC layer and the MAC layer of the CG1 in turn, then reaches the MAC layer and the RLC layer of the UE through the air interface, and finally converges to the PDCP layer of the UE; and the Duplicated PDCP PDU passes through the RLC layer and MAC of the non-anchor CG (CG2) in turn. The layer then arrives at the MAC layer and the RLC layer of the UE through the air interface, and finally converges to the PDCP layer of the UE. When the PDCP layer of the UE detects that the two PDCP PDUs are the same, one of the PDCP PDUs is discarded, and the remaining PDCP PDU is uploaded to the UE. High level. Taking FIG. 3 as an example, the PDCP layer of the UE copies the PDCP PDU into the same two copies, one of which is the original PDCP PDU and the other is the duplicate Duplicated PDCP PDU. The original PDCP PDU passes through the RLC layer and the MAC layer of the UE in turn, then reaches the MAC layer and the RLC layer of the CG1 through the air interface, and finally converges to the PDCP layer of the CG1; and the Duplicated PDCP PDU passes through the RLC layer and the MAC layer of the UE in turn, and then passes through the air interface. The MAC layer and the RLC layer of the CG2 are finally aggregated to the PDCP layer of the CG1 through the X2 interface. When the PDCP layer of the CG1 detects that the two PDCP PDUs are the same, one of the PDCP PDUs is discarded, and the remaining PDCP PDU is uploaded to the network side. High level. Based on the transport protocol architecture of FIG. 2 and FIG. 3, when the PDCP layer is located in the MCG, it is called the MCG split bearer, and if the PDCP layer is located in the SCG, it is called the SCG split bearer. In the related art, both the MCG and the SCG have the data replication transmission capability of a certain bearer activated or deactivated by a MAC control unit (CE, Control Element), and can also control the data replication transmission of a certain bearer through an RRC message. .

According to the prior art data replication transmission scheme of the related art, whether the DC architecture or the CA architecture, the copied PDCP PDUs are separately transmitted to different carriers. In the 5G new radio (NR, New Radio) technology, the system bandwidth of the system carrier is often greater than 20MHz, for example, 100MHz compared to the LTE system. In order to improve the carrier scheduling efficiency, the network can configure one or the terminal in the system bandwidth. Multiple BWPs. Each BWP can be considered as a separate part of the system bandwidth. Therefore, in a single carrier, a data replication transmission scheme can be implemented by BWP.

Based on the above description, the following embodiments are proposed.

Embodiment 1

Referring to FIG. 4, a method for data replication transmission according to an embodiment of the present invention is shown. The method may be applied to a terminal, and the method may include:

S401: Receive an uplink grant (UL grant, UpLink grant);

It should be noted that a base station, such as an eNB in an LTE system or a gNB in a 5G NR system, may carry an uplink grant (DCI, Downlink Control Information) through a physical downlink control channel (PDCCH, Physical Downlink). The Control Channel is sent to the terminal; specifically, in the related art, the DCI has multiple formats, such as DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 2B, 3, 3A, 4. In the embodiment of the present invention, the UL grant may be preferably sent to the terminal through the PDCCH through the DCI format 0 format. Therefore, the terminal can receive the DCI through the PDCCH to acquire the UL grant for the authorized BWP.

S402: Obtain a BWP corresponding to the uplink grant UL grant.

In order to enable the terminal to specifically learn the location of the BWP in the system bandwidth, in the embodiment of the present invention, step S402 may specifically include:

Determining the BWP according to the description parameter that includes the BWP in the uplink grant UL grant, where the description parameter of the BWP includes at least one of the following: a basic parameter set of the BWP, a Numerology, used to identify the BWP Carrier spacing SCS; a center frequency of the BWP and a bandwidth of the BWP;

or,

The BWP in which the uplink grant UL grant is located is used as the BWP.

Understandably, in a 5G NR system, the maximum system bandwidth may be 100 MHz or even higher, and therefore, the bandwidth of the BWP is less than or equal to the maximum system bandwidth described above.

It should be noted that, after receiving the uplink grant UL grant delivered by the eNB or the gNB, the terminal can obtain the UL grant by parsing the DCI in the PDCCH.

Specifically, the UL grant may be a UL grant that is dynamically scheduled, that is, a UL grant with a Cell Radio Network Temporary Identifier (C-RNTI), or a semi-static configuration. (configured) UL grant, that is, a UL grant with an Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) as an address.

S403: Select one or a group of logical channels associated with the BWP according to the pre-configured logical channel restriction parameter according to the pre-configured logical channel restriction parameter;

S404: The data to be sent of the one or a group of logical channels is multiplexed onto the UL grant resource for transmission.

Specifically, for S404, multiplexing the data to be sent of the one or a group of logical channels to the UL grant resource may be implemented according to a logical channel priority (LCP) criterion in the current NR related technology. Transfer on.

Through the technical solution shown in FIG. 4, it can be seen that after the system carrier is divided into multiple BWPs, the uplink authorization resources of the data duplication transmission (data duplication) can be determined by the BWP corresponding to the uplink authorization, thereby improving the reliability of the data transmission. At the same time, the system bandwidth is fully utilized.

For the technical solution shown in FIG. 4, the BWP is a BWP in an active state on the current carrier; the BWP in the activated state indicates that the terminal expects to receive and transmit a signal on the bandwidth specified by the BWP, specifically including the upper and lower sides of the data. Line transmission, receiving system messages, and so on. And the current carrier includes one or more BWPs in an activated state.

For the technical solution shown in FIG. 4, the pre-configured logical channel restriction parameter is used to indicate logic corresponding to two radio link control layer RLC entities associated with the packet data convergence protocol layer PDCP layer of the terminal for the current carrier. The channels are respectively configured with one or a group of BWP labels; wherein the BWPs configured by the corresponding logical channels of the two RLC entities are different. When the logical channel corresponding to the RLC entity is configured with a set of BWPs in an active state, the BWP may be a BWP index. The BWP configured in the logical channel corresponding to the RLC entity may be different. Understandably, a single BWP can be configured as multiple logical channels at the same time, and the BWPs configured by a single logical channel are different from each other.

It can be understood that, by using the technical solution shown in FIG. 4, since data copy transmission can be implemented by two BWPs or two sets of BWPs on the current carrier, the current carrier can be referred to as a carrier having a single carrier data copy transmission function. Specifically, the data radio bearer (DRB) or the signal radio bearer (SRB) may be included. The BWPs in the current carrier may be divided according to the number of LCHs corresponding to the RLC entities, so that the BWPs configured by the respective LCHs of the respective RLC entities are different.

Referring to the protocol structure for performing data duplication transmission shown in FIG. 5, the base station eNB or gNB is configured to send a UL grant for BWP #1 and BWP #2 in the system bandwidth; understandably, BWP #1 and BWP# 2 may respectively represent a BWP in the system bandwidth of the current carrier, or may respectively represent a group of BWPs in the system bandwidth of the current carrier. When it is necessary to be stated, when a group of BWPs is represented, it can be understood that in the BWP#1 group Or in the BWP#2 group, the BWPs are different from each other, and the same BWP can be configured to the BWP#1 group or the BWP#2 group at the same time.

Moreover, both BWP#1 and BWP#2 are BWPs that are active on the current carrier, and are BWPs configured by the logical channel LCH corresponding to each of the RLC entity A and the RLC entity B, and the terminal can pass BWP#1 and BWP#2. Transfer data and receive system messages, etc. After receiving the UL grant, the terminal selects to multiplex the data to be transmitted of one of the two logical channels to the BWP #1 and BWP #2 for the UL grant according to the BWP index of the logical channel configuration. . In detail, the PDCP layer replicates the configured duplication according to the PCDP SDU configuration data, so that the original PDCP PDU and the duplicated PDCP PDU (Duplicated PDCP PDU) can be obtained, and then the PDCP PDU enters the MAC through the RLC Entity B through the RLC entity A and the Duplicated PDCP PDU. The layer then transmits the PDCP PDU and the Duplicated PDCP PDU to the BWP #1 and BWP #2 through the MAC layer for transmission.

This embodiment provides a data replication transmission method, which implements data duplication transmission by an authorized BWP, thereby fully utilizing system bandwidth while improving data transmission reliability.
