Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
For a Data Duplication (Data Duplication) transmission scheme in the related art, it should be noted that, for a CA architecture, see fig. 1, which shows a protocol structure for Data Duplication (Data Duplication) transmission under a CA architecture provided in the related art, as can be known from fig. 1, a PDCP layer configures Data Duplication according to a PCDP Service Data Unit (SDU), so that an original PDCP PDU and a Duplicated PDCP PDU (Duplicated PDCP PDU) can be obtained, and then the PDCP PDU passes through a Radio Link Control (RLC) Entity (RLC Entity) a, and the Duplicated PDCP PDU enters a Medium Access Control (MAC) layer through an RLC Entity B, and then the PDCP PDU and the Duplicated PDCP PDU are respectively set on different physical carriers through the MAC layer for transmission.
For the DC architecture, a serving Cell Group provided by the Master base station MeNB is referred to as a Master Cell Group (MCG), and a serving Cell Group provided by the Secondary base station SeNB is referred to as a Secondary Cell Group (SCG). The Cell Group (CG) in which the PDCP layer is located is called an anchor Cell Group (anchor CG), so the anchor CG is generally an MCG. Referring to fig. 2 and fig. 3, which illustrate a Protocol structure for Data Duplication (Data Duplication) transmission under a DC architecture provided in the related art, taking fig. 2 as an example, a PDCP layer of an anchor CG (CG1) duplicates PDCP Protocol Data Units (PDUs) into two identical copies, where one copy is an original PDCP PDU and the other copy is a Duplicated PDCP PDU. The original PDCP PDU passes through the RLC layer and the MAC layer of the CG1 in sequence, reaches the MAC layer and the RLC layer of the UE through an air interface, and finally converges to the PDCP layer of the UE; the Duplicated PDCP PDU sequentially passes through an RLC layer and an MAC layer of the non-anchor CG (CG2), reaches the MAC layer and the RLC layer of the UE through an 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 PDCP PDU is discarded, and the rest PDCP PDU is uploaded to the upper layer of the UE. Taking fig. 3 as an example, the PDCP layer of the UE copies the PDCP PDU into two identical copies, wherein one is the original PDCP PDU and the other is the copied Duplicated PDCP PDU. The original PDCP PDU passes through the RLC layer and the MAC layer of the UE in sequence, reaches the MAC layer and the RLC layer of the CG1 through an air interface, and finally converges to the PDCP layer of the CG 1; the Duplicated PDCP PDU sequentially passes through an RLC layer and an MAC layer of the UE, reaches the MAC layer and the RLC layer of the CG2 through an air interface, and finally converges to the PDCP layer of the CG1 through an X2 interface; when the PDCP layer of the CG1 detects that two PDCP PDUs are the same, it discards one of the two PDCP PDUs and uploads the remaining one to a higher layer on the network side. Based on the transport protocol architecture of fig. 2 and 3, when the PDCP layer is located in the MCG, it is called MCG Split Bearer (MCG Split Bearer), and if the PDCP layer is located in the SCG, it is called SCG Split Bearer (SCG Split Bearer). In the related art, both the MCG and the SCG have a data duplication transmission capability that activates or deactivates a certain bearer through a MAC Control Element (CE), and also can Control data duplication transmission of a certain bearer through an RRC message.
The existing data duplication transmission scheme by the above-described related art, whether in the DC architecture or the CA architecture, transmits duplicated PDCP PDUs to different carriers, respectively. In the 5G New Radio over the air (NR, New Radio) technology, compared to the LTE system, the system bandwidth of the system carrier is often greater than 20MHz, for example, 100MHz, and in order to improve carrier scheduling efficiency, the network may configure one or more BWPs for the terminal in the system bandwidth. And each BWP can be considered as mutually independent parts in the system bandwidth, therefore, in a single carrier, a data copy transmission scheme can be implemented by BWP.
Based on the above explanation, the following embodiments are proposed.
Example one
Referring to fig. 4, it illustrates a method for data replication transmission provided by an embodiment of the present invention, where the method may be applied to a terminal, and the method may include:
s401: receiving an UpLink grant (UL grant, UpLink grant);
it should be noted that, a base station, for example, an eNB in an LTE system or a gNB in a 5G NR system, may send an uplink grant to a terminal through a Physical Downlink Control Channel (PDCCH) by carrying the uplink grant in Downlink Control Information (DCI); specifically, in the related art, the DCI has a plurality of formats, such as DCI formats 0, 1A, 1B, 1C, 1D, 2A, 2B, 3A, 4. In the embodiment of the present invention, the UL grant may be preferably transmitted to the terminal through the PDCCH in the DCI format 0 format. Accordingly, the terminal may acquire the UL grant for the authorized BWP by receiving the DCI through the PDCCH.
S402: acquiring a BWP corresponding to the uplink grant UL grant;
in order to enable the terminal to specifically know the position of the BWP in the system bandwidth, in this embodiment of the present invention, step S402 may specifically include:
determining the BWP according to the description parameters of the BWP included in the uplink grant UL grant, wherein the description parameters of the BWP at least include any one of the following items: a base parameter set Numerology for the BWP to identify a carrier spacing, SCS, for the BWP; the center frequency point of the BWP and the bandwidth of the BWP;
alternatively, the first and second electrodes may be,
and taking the BWP where the uplink grant UL grant is located as the BWP.
It is understood that in the 5G NR system, the maximum system bandwidth may be 100MHz or even higher, and thus, the bandwidth of the BWP is less than or equal to the above maximum system bandwidth.
It should be noted that, after receiving the uplink grant UL grant issued by the eNB or the gNB, the terminal can obtain the UL grant by analyzing DCI in the PDCCH.
Specifically, the UL grant may specifically be a dynamically scheduled UL grant, that is, a UL grant with a Cell Radio Network Temporary Identifier (C-RNTI) as an address (address), or may be a semi-statically Configured (Configured) UL grant, that is, a UL grant with a Configured scheduled Radio Network Temporary Identifier (CS-RNTI) as an address (address).
S403: selecting one or a group of logical channels having an association relationship with the BWP according to the preconfigured logical channel restriction parameters;
s404: multiplexing the data to be sent of the logical channel or the group of logical channels to the UL grant resource for transmission.
Specifically, for S404, multiplexing data to be sent of the one or a group of Logical channels onto the UL grant resource for transmission may be implemented according to a Logical Channel Priority (LCP) criterion in the current NR correlation technique.
Through the technical scheme shown in fig. 4, it can be seen that after the system carrier is divided into a plurality of BWPs, an uplink grant resource for implementing data replication transmission (data replication) can be determined by the BWP corresponding to the uplink grant, so that the reliability of data transmission is improved, and the system bandwidth is fully utilized.
For the technical solution shown in fig. 4, the BWP is a BWP in an active state on a current carrier; the active BWP indicates that the terminal desires to receive and transmit signals over a bandwidth defined by the BWP, specifically including uplink and downlink transmissions of data, receiving system messages, and so on. And the current carrier includes one or more BWPs in an active state.
For the technical solution shown in fig. 4, the preconfigured logical channel restriction parameters are used to indicate that, for the current carrier, one or a group of BWP flags are respectively configured for logical channels corresponding to two RLC entities associated with a packet data convergence protocol layer PDCP layer of the terminal; wherein, the logical channels corresponding to the two RLC entities have different BWPs. When a logical channel corresponding to the RLC entity configures a set of active BWPs, the logical channel may specifically be in the form of a BWP index (index); it should be noted that, the logical channels corresponding to the RLC entities have different configured BWPs, and it should be understood that a single BWP may be simultaneously configured as multiple logical channels, and the configured BWPs of the single logical channels are different from each other.
It can be understood that, with the technical solution shown in fig. 4, since Data replication transmission may be implemented by two BWPs or two sets of BWPs on the current carrier, the current carrier may be referred to as a carrier with a single carrier Data replication transmission function, and specifically may include a Data Resource Bearer (DRB) or a Signaling Resource Bearer (SRB). The BWP 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 LCHs corresponding to the RLC entities are different.
Referring to the protocol structure for data replication (data replication) transmission shown in fig. 5, it is assumed that a base station eNB or a gNB transmits a UL grant for BWP # 1 and BWP # 2 in a system bandwidth; it should be understood that BWP # 1 and BWP # 2 may respectively represent one BWP in the system bandwidth of the current carrier, and may also respectively represent a group of BWPs in the system bandwidth of the current carrier, and when it should be noted that, when a group of BWPs is represented, it is understood that BWPs in BWP # 1 group or BWP # 2 group are different from each other, and the same BWP may be configured to BWP # 1 group or BWP # 2 group at the same time.
The BWP # 1 and BWP # 2 are both BWPs in active state on the current carrier, and are respectively BWPs configured for the logical channels LCH corresponding to the RLC entity a and the RLC entity B, and the terminal can transmit data and receive system messages and the like through BWP # 1 and BWP # 2. And then after the terminal receives the UL grant, according to the BWP index configured by the logical channel, selecting to-be-transmitted data of one logical channel of the two logical channels to be multiplexed to BWP # 1 and BWP # 2 corresponding to the UL grant for transmission. In detail, the PDCP layer copies configured duplicate according to the PCDP SDU configuration data, so that an original PDCP PDU and a duplicate PDCP PDU (Duplicated PDCP PDU) can be obtained, and then the PDCP PDU passes through the RLC Entity a, the Duplicated PDCP PDU enters the MAC layer through the RLC Entity B, and then the PDCP PDU and the Duplicated PDCP PDU are respectively set on BWP # 1 and BWP # 2 for transmission through the MAC layer.
The embodiment provides a data replication transmission method, which implements data replication transmission (data replication) by authorized BWP, thereby fully utilizing system bandwidth while improving data transmission reliability.

For the technical solution shown in fig. 6, the BWP is determined by the description parameters including the BWP, where the description parameters of the BWP at least include any one of the following: a base parameter set Numerology for the BWP to identify a carrier spacing, SCS, for the BWP; the center frequency point of the BWP and the bandwidth of the BWP; or the BWP where the uplink grant UL grant is located is the BWP corresponding to the uplink grant.
In addition, the UL grant may specifically be a dynamically scheduled UL grant, that is, a UL grant with a Cell Radio Network Temporary Identifier (C-RNTI) as an address (address), or a semi-statically configured UL grant, that is, a UL grant with a CS-RNTI as an address.

And the current carrier includes one or more BWPs in an active state.
And, the pre-configured logical channel restriction parameter is used to indicate that for the current carrier, one or a group of BWP marks are respectively configured for the logical channels corresponding to the two RLC entities of the radio link control layer associated with the PDCP layer of the packet data convergence protocol layer of the terminal; wherein, the logical channels corresponding to the RLC entities have different BWPs configured therein.
