Embodiment
The method of joint transmission of the present invention is as shown in Figure 1 to be comprised:
The application scenarios of joint transmission is mainly two joint transmission between the different system among the present invention, and two different systems here are for using two Radio Network Systems of different radio access technologies.When disposing the joint transmission network, generally from these two different systems, choose a network element device as the anchor point network element, for example by operator:
In the LTE system, eNB is set to the anchor point network element of joint transmission; In the UMTS system, RNC is set to the anchor point network element of joint transmission.
Wherein, the LTE system can also be divided into LTE TDD system and LTE FDD system, in these two systems, can eNB or home eNB be set to the anchor point network element of joint transmission.
Can carry out joint transmission between above-mentioned any two systems of mentioning.
Confirm after the anchor point network element that need between the MAC layer of the rlc layer of anchor point network element and another network element, set up data-interface, the foundation of this data-interface is carried out by described anchor point network element and another network element.
Need to prove here; The anchor point network element can also adopt other title; Access network elements (radio network controller among the UMTS, or the base station among the LTE), master network element or UE like the initial connecting system of UE register access network elements of (Attach) system or the like.
The essence of this step is; The rlc layer of anchor point network element will be distributed from the downlink data on upper strata (has two paths available; Promptly directly send to the MAC layer of this network element, send to the MAC layer of another network element through data-interface); When distributing, also adopt following mode to carry out the selection in path:
Mode one: the rlc layer of anchor point network element sends to a quality of wireless channel side preferably with downlink data.Concrete, can obtain the quality of wireless channel of the sub-district that each system controlled through the measurement and report of UE, after comparing, downlink data is sent to the quality of wireless channel MAC layer of network element in the side system preferably.
Mode two: the rlc layer of anchor point network element sends to the lower side of offered load with downlink data.Concrete, each system all can be through measuring the load that obtains native system, and the anchor point network element can compare the load of two systems, thereby knows the network that load is lower.The rlc layer of anchor point network element sends to downlink data on the MAC layer of the network element in the lower side system of load.
Mode three: the rlc layer of anchor point network element does not serve as that foundation is carried out the distribution of downlink data with two system wireless channel qualities or loading condition, but downlink data is distributed to the MAC of two systems layer according to fixing ratio simultaneously.For example, can be with the ratio simultaneously MAC layer distribution of network element to two systems in of downlink data according to 1: 1.Certainly, the distribution that can also carry out according to other ratio.
Aforesaid way one can be called dynamical fashion with mode two, and mode three can be called fixed form.
In order to realize joint transmission, also need carry out dual mode configuration: set up anchor point network element place system corresponding protocols stack and another network element place system corresponding protocols stack in UE inside for UE; And between the MAC layer of the rlc layer of anchor point network element place system corresponding protocols stack and another network element place system corresponding protocols stack, set up data-interface.Specifically will explain through follow-up embodiment here.
When carrying out joint transmission:
For downlink data, UE receives the downlink data from the MAC layer of anchor point network element, and sends to the upper strata behind MAC layer through the inner anchor point network element of UE place system corresponding protocols stack and the rlc layer; And/or; UE receives the downlink data from the MAC layer of another network element; And after sending to the rlc layer of the inner anchor point network element of UE place system corresponding protocols stack by the MAC layer of inner another network element place system corresponding protocols stack of UE through the inner data-interface of UE, send to the upper strata.
In addition, the method for joint transmission of the present invention can also be applied to transmission of uplink data: the rlc layer of anchor point network element sends to the upper strata after receiving and sending to the upper strata behind the upstream data from the MAC layer of this network element and/or receive the upstream data from the MAC layer of another network element through data-interface.
Concrete: after rlc layer, MAC layer and the physical layer of upstream data from the upper strata, send to the anchor point network element through the inner anchor point network element of UE place system corresponding protocols stack; And/or; After sending to the MAC layer and physical layer of inner another network element place system corresponding protocols stack of UE by the rlc layer of the inner anchor point network element of UE place system corresponding protocols stack through the inner data-interface of UE from the upstream data on upper strata, send to another network element.
For the joint transmission of upstream data, network sends dispatching command to UE, and a side and the opposite side (being the side that non-anchor point network element belongs to system) of the anchor point network element of UE place system carried out uplink scheduling.UE carries out transmitting uplink data according to the scheduling of network in anchor point and non-anchor point two systems.
Need to prove that up joint transmission is a possibility, promptly for transmitting uplink data, the joint transmission of the said upstream data of employing preamble that UE and network side are optional.
For transfer of data, the network element of process and corresponding layer were confirmed when data were transmitted in a system, therefore, just can confirm above-mentioned another network element (MAC layer) according to the difference of system.
Through concrete instance joint transmission scheme of the present invention is described below.
Among the present invention, carrying out under the scene of joint transmission between two different systems, UE possesses dual mode configuration, and promptly UE can use two kinds of wireless communication technologys simultaneously, can be simultaneously in the enterprising data transfer of the frequency band of these two kinds of networks.For this reason, in UE inside the data-transformation facility part is divided according to dual-mode network.
The present invention is that example describes with LTE system and UMTS system.
UE can use LTE and two kinds of wireless access technologys of UMTS to carry out transfer of data simultaneously, and so, UE can polymerization LTE in LTE and the common region covered of UMTS and the carrier wave of UMTS, promptly obtains the data transport service of LTE sub-district and UMTS sub-district simultaneously.
For this reason, in UE inside data-transformation facility is divided into UMTS side and LTE side.The LTE side has the protocol stack structure of LTE, is respectively PDCP layer, rlc layer, MAC layer etc. from top to bottom, the LTE standard of all following such as mutual between the function of each layer, operation principle and each layer; The UMTS side has the protocol stack structure of UMTS, is respectively PDCP layer, rlc layer, MAC layer etc. from top to bottom, the UMTS standard of all following such as mutual between the function of each layer, operation principle and each layer.
In addition, for the exchanges data of UMTS side and LTE side, can between inner UMTS side of UE and LTE side, a data interface be set.
Embodiment one, the eNB (abbreviating LTE eNB as) of LTE system is set to the anchor point network element of joint transmission, owing to can confirm that another network element in the UMTS system is RNC, is UMTS RNC.
In such cases, the protocol stack structure of UE inside is as shown in Figure 2, and the LTE side has PDCP layer, rlc layer, MAC layer etc.; The UMTS side has MAC layer etc.In order to realize the exchanges data of UMTS side and LTE side, can set up a data interface at the rlc layer of the MAC of UMTS side layer and LTE side.
Among this embodiment, the deployment of network is as shown in Figure 3, wherein; The sub-district that Cell 1 provides for LTE eNB; The sub-district that Cell 2 provides for UMTS NodeB, UE is in the intersection overlay area of two sub-districts, in order to realize joint transmission; Need between anchor point network element LTE eNB and another network element UMTS RNC, set up a data interface, be used for carrying out transfer of data.
Because the anchor point network element is LTE eNB, carry out the UE of transfer of data so for this scheme of use, its downlink data is all from the LTE core net, and upstream data all is sent to the LTE core net through LTE eNB.
If UE uses the carrier wave of LTE and UMTS to carry out transfer of data simultaneously, be under the situation of anchor point network element with LTE eNB, the downlink data that comes from the LTE core net at first arrives LTE eNB.LTE eNB distributes downlink data, supposes to adopt fixed form, and the result of distribution is: a part of downlink data directly sends to UE by LTE eNB; Another part downlink data sends to UMTS RNC through the data-interface of LTE eNB and UMTS RNC earlier; Send to UE through UMTS NodeB again; Then be illustrated in figure 4 as the flow direction of downlink data (network side is to UE), comprise two paths: the one, LTE eNB → UE; The one, LTE eNB → UMTS RNC → UMTS NodeB → UE, upstream data (UE is to network side) flow to opposite.
Concrete, the transmission course of downlink data is as shown in Figure 5 among this embodiment, comprising:
Step 502 after the RLC process of RLC SDU through LTE eNB, constitutes one or more RLCPDU.
For transmitting uplink data, the transmission path of its path and the described downlink data of Fig. 5 is opposite.
After UE received downlink data, according to the protocol stack structure in the UE shown in Figure 2, downlink data in the inner transmission course of UE was:
The MAC layer of UMTS side receives the part downlink data that the UMTS system sends, and through the data-interface of UMTS side and LTE side, after this part downlink data is sent to the rlc layer of LTE side, re-sends to last layer;
LTE side MAC layer receives the part downlink data that the LTE system sends, and through the rlc layer of LTE side, re-sends to last layer then.
For transmitting uplink data, its transmission path at inner transmission path of UE and above-mentioned downlink data is opposite.
Embodiment two, be the anchor point network element, can confirm that then another network element is LTE eNB with UMTS RNC.
In such cases, the protocol stack structure of UE inside is as shown in Figure 6, and the UMTS side has the protocol stack structure of UMTS, is respectively PDCP layer, rlc layer, MAC layer etc. from top to bottom; The LTE side has MAC layer etc.In order to realize the exchanges data of UMTS side and LTE side, can a data interface be set at the rlc layer of UMTS side and the MAC layer of UMTS side.
Among this embodiment, the deployment of network is as shown in Figure 7, wherein; The sub-district that Cell 1 provides for UMTS NodeB; The sub-district that Cell 2 provides for LTE eNB, UE is in the intersection overlay area of two sub-districts, in order to realize joint transmission; Need between another network element LTE eNB and anchor point network element UMTS RNC, set up a data interface, be used for carrying out transfer of data.
Because the anchor point network element is UMTS RNC, carry out the UE of transfer of data so for this scheme of use, its downlink data is all from the UMTS core net, and upstream data all is sent to the UMTS core net through UMTS RNC.
If UE uses the carrier wave of LTE and UMTS to carry out transfer of data simultaneously, be under the situation of anchor point network element with LTE eNB, the downlink data that comes from the UMTS core net at first arrives UMTS RNC.UMTS RNC distributes downlink data, supposes to adopt fixed form, and the result of distribution is: a part of downlink data sends to UE by UMTS RNC through UMTS NodeB; Another part downlink data sends to LTE eNB through the data-interface of LTE eNB and UMTS RNC earlier by UMTS RNC; Send to UE by LTE eNB again; Then be illustrated in figure 8 as the flow direction of downlink data (network side is to UE), comprise two paths: the one, UMTS RNC → LTE eNB → UE; The one, UMTS RNC → UMTSNodeB → UE, upstream data (UE is to network side) flows to opposite.
Concrete, the transmission course of downlink data is as shown in Figure 9 among this embodiment, comprising:
Step 902 after the RLC process of RLC SDU through UMTS RNC, constitutes one or more RLC PDU.
For transmitting uplink data, the transmission path of its path and the described downlink data of Fig. 9 is opposite.
After UE received downlink data, according to the protocol stack structure in the UE shown in Figure 6, downlink data in the inner transmission course of UE was:
The MAC layer of UMTS side receives the part downlink data that the UMTS system sends, and through the rlc layer of UMTS side, re-sends to last layer then;
Behind the rlc layer of LTE side, re-send to last layer;
The MAC layer of LTE side receives the part downlink data that the LTE system sends, and through the data-interface of UMTS side and LTE side, this part downlink data is sent to the rlc layer of UMTS side, re-sends to last layer.
For transmitting uplink data, its transmission path at inner transmission path of UE and above-mentioned downlink data is opposite.
It is to be noted; RLC PDU for UMTS RNC generation; If be sent to the MAC layer of LTE eNB, the MAC layer of LTE eNB will have the function that the encryption (ciphering) identical with the PDCP layer, deciphering (deciphering), integrity protection (integrity protection) and integrality are verified (integrity verification) so.For downlink data; When the MAC of LTE eNB layer is received the RLC PDU from UMTS RNC; Can be at first carry out the ciphering operation, and, can also carry out integrity protection operation for the data of chain of command (control plane) to this RLC PDU.In the LTE of UE side, the MAC layer is received the MAC PDU from lower floor, after handling through MAC layer process, carries out integrality and verifies (integrity verification) and deciphering (deciphering) processing, sends to the rlc layer of UMTS RNC at last.
