Carry out the embodiment that the present invention will be described in detail below with reference to embodiment, whereby to the present invention how application technology hand Section solves technical problem, and the realization process for reaching technical effect can fully understand and implement.
In a region MBSFN, the MCE by managing the region MBSFN configures each carrying MBMS in the region MBSFN The resource information of unicast and/or PMCH in the carrier wave of business, and the resource information is sent to the base station in the region MBSFN.Its In, the resource information of unicast is used to describe to send the resource of unicast data, control letter the present and the corresponding reference signal of unicast, Described in resource specifically include ePDCCH, PDSCH or ePHICH, wherein reference signal includes RCRS, CRS, CSI-RS, DMRS. Preferably, the unicast service in unicast resource is using extension CP transmission.Here unicast includes point-to-point unicast service and unicast System broadcast information, be also possible to describe D2D business UE D2D communication resource distribution.The resource information of the PMCH is used for Description sends the resource of MBMS data, control signaling and the corresponding reference signal of MBMS business, wherein specifically including MTCH or MCCH, wherein reference signal includes the reference signal for MBMS business.Preferably, do not allow in the unicast resource CSI-RS configuration, because CSI-RS is to send in the period, if including MBSFN and non-in the subframe of configuration CSI-RS in the period MBSFN can have an impact to the frequency domain position of CSI-RS, to influence the dispatching efficiency of PDSCH.It actually can also be in the list It broadcasts and transmits CSI-RS in resource, only base station needs to avoid the CSI of the unicast resource in MBSFN sub-frame to survey when dispatching PDSCH Measure scheduling of the result for unicast service in non-MBSFN sub-frame.
After receiving upper layer node MCE and being unicast and/or PMCH resource information by the transmission of M2 interface, base station is logical for base station The resource information is sent to UE by the system broadcast channel for crossing the corresponding carrier wave of the resource information, or passes through the resource The system broadcast channel or dedicated channel of the pairing carrier wave of the corresponding carrier wave of information are sent to UE, and the corresponding carrier wave described at this time can To be non-independent operation new carrier wave, the system broadcast information is preferably SIB2, when UE can be made to receive SIB2 in this way, once Property know that MBSFN sub-frame distributes information, save UE and determine the time-consuming of PMCH.
The resource information of the unicast is used to describe in MBSFN sub-frame or in the subframe of carrying PMCH to be unicast allocated Or time and/or frequency resource for unicast reservations, specifically include following one or more forms: 1) for unicast allocated or Reserved PRB pair resource.In this case it is that unicast uses first OFDM symbol that PRB pair, which is since subframe,.2) it is Unicast allocated or reserved OFDM symbol resource.In this case OFDM symbol is located in subframe first 1 or 2 OFDM, Or 1 or 2 OFDM symbols after being located in subframe.When positioned at latter 1 or 2 OFDM symbols, can to avoid with other carrier waves In first 1 or 2 OFDM symbols in signal it is interfering with each other, especially send PDCCH in first 1 or 2 OFDM symbols When the case where having used relatively high power, if sending ePDCCH in first 1 or 2 OFDM symbols in the same subframe of adjacent area, that Interference can be very big, so sending ePDCCH using 1 after subframe or 2 OFDM symbols.It 3) is unicast allocated Or reserved frequency resource.In this case, frequency resource is configured for unicast, unicast service is only in the frequency resource of distribution Interior operation.It 4) is unicast allocated or reserved sub-carrier resources.In this case, it is suitably for unicast and configures less resource, example As resource is not more than 12 subcarriers.It 5) is unicast allocated or reserved bandwidth resources.Such case is the unicast in agreement With PMCH in the MBSFN subframe frequency division when, be the certain bandwidth of unicast allocated.
If carry out frequency division multiplexing in view of unicast and PMCH (carrying multiple cell MBMS business), since PMCH channel is What multi-plot joint was sent, it, can be to close to the unicast on subcarrier so signal strength is very big so signal will do it superposition Business forms interference, in order to avoid this interference, when distributing the resource information of unicast, there are unicast and PMCH frequency division the case where When, the unicast resource distributed in the resource information of unicast may include protection band resource (also referred to as reserved resource).Wherein protect Band is in the frequency direction between unicast and PMCH.The size of protection band can be network side and receiving end arranges in advance. It can be the protection interval of subcarrier formal definition or the protection interval of PRB formal definition.When with subcarrier formal definition protection When interval, can arrange protection interval is 5 or 6 null subcarriers between unicast and PMCH.Protection band resource is located at unicast With PMCH boundary, when PMCH and unicast are there are when multiple boundaries, then each boundary has required protection band.For example, PMCH is located at the centre of bandwidth, and unicast resource is located at both sides, just there is 2 boundaries at this time, then needs 2 protection bands.The region MBSFN The unicast resource constituted in the carrier wave in the region MBSFN between interior each cell can be different.For example, in the same region MBSFN Two cells in, the unicast resource in the MBSFN sub-frame of cell 1 is different from the unicast resource in the MBSFN sub-frame of cell 2. Such case is conducive to the ePDCCH between adjacent area and cooperates, avoid each other due to resource is identical and generate interference.
The resource information of the PMCH be used to describe in MBSFN sub-frame or the subframe of carrying PMCH in for PMCH distribution when Between and/or frequency resource, specifically include following one or more forms: 1) for PMCH distribution PRB pair resource.Such case Under, MCE needs to distribute identical PMCH resource for cell each in the same region MBSFN.It 2) is the OFDM symbol of PMCH distribution Resource；It 3) is the frequency resource of PMCH distribution；It 4) is the sub-carrier resources of PMCH distribution；It 5) is the bandwidth resources of PMCH distribution. Optionally, protection band resource above-mentioned also may be embodied in the PMCH resource distributed by the resource information of PMCH, single at this time It broadcasts in resource no longer comprising protection band resource.The specific implementation of protection band is identical as in unicast resource.
The resource information of PMCH can also be provided by following mode: in the MBSFN subframe or in the son for carrying PMCH In frame other than the resource of unicast, remaining resource is all the resource for PMCH distribution, wherein if in MBSFN sub-frame or held Carrying in the subframe of PMCH has protection band, then unicast resource includes the protection band.The protection band is reserved as unit of subcarrier. Alternatively, when there is no protection band, when PMCH resource by unicast resource description to provide when, in the MBSFN subframe or carrying In the subframe of PMCH other than unicast resource, remaining resource is PMCH.
When unicast resource in subframe using PRB pair as unit when, corresponding PMCH resource is also as unit of PRB pair.
When network side is described with unicast and PMCH resource information, refer to that network side describes to be used in MBSFN sub-frame respectively The resource of unicast resource and PMCH.PMCH resource information sends MBMS data and MBMS control relevant letter the present for describing Resource, wherein specifically including MTCH or MCCH.
Further, PMCH resource information can be used for the resource that description sends particular service data and control signaling, Described in addition to particular service data are the unicast service that transmission mode except MBMS business and LTE R11 and before is supported Business, such as MTC service, the transmission mode that LTE R12 is newly introduced, D2D business datum and relevant control letter are modern.It can make in this way These particular services send and receive the business in the unicast resource in MBSFN sub-frame and do not have an impact.It needs exist for It is described the information of the resource practical use in PMCH resource information, such as is really PMCH or is unicast service or MTC Business or D2D business etc..
Further, PMCH resource information, which can be used for description PMCH resource, is distributed for MBMS business, but only It is used for transmission unicast service.Such case is similar with above-mentioned particular service purposes.For example, in order to avoid legacy version UE exists The influence that unicast service is received in MBSFN unicast resource or in non-MBSFN sub-frame, can provide some highest version UE in PMCH Unicast traffic in the resource of source information instruction.Here influence is primarily referred to as: if not taking aforesaid way, legacy version UE Will the blind examination in the resource of data for not belonging to itself, to judge whether there is the data for belonging to itself.Need exist for PMCH It is described the information of the resource practical use in resource information, such as is really PMCH or is unicast service or MTC service Or D2D business etc..
Base station receives the unicast in the region MBSFN that MCE is sent and/or the resource information of PMCH as receiving end, and parses The letter of the resource information and/or PMCH resource information that form unicast is modern, the system broadcasts letter in the corresponding carrier wave 1 of the signaling Breath or dedicated channel send the signaling, or the system broadcast information in the pairing carrier wave 2 of the corresponding carrier wave 1 of the signaling Or dedicated channel sends the signaling.The wherein preferred SIB2 of system broadcast information can make UE obtain MBSFN sub-frame in this way The letter that unicast or PMCH resource information are obtained while configuration information is modern, simplifies UE and receives process.
