Background technique

In LTE R11, begin to that a kind of new carrier type is discussed, but in LTE R11 stage, the standardization of new carrier wave Work is not completed, currently, coming into the LTE R12 stage, the standardization effort of new carrier wave is postponed in LTE R12, and And there are some preliminary conclusions and introduce some new functions again.

For new carrier wave by as a kind of related work that new carrier type is being standardized, here is in new carrier wave Some Consensus conclusions:

Using single port cell-specific pilot tone (CRS) the Lai Zhihang synchronized tracking in 5 milliseconds of (5ms) periods (text in new carrier wave In have a referred to as 5msCRS, or be synchronized tracking CRS), it is clear that be here not identical with the CRS in existing system, and support Port number is different, and sending cycle is different.

In new carrier wave in especially synchronous new carrier wave, currently discuss whether configure transmission PSS/SSS and 5msCRS, it is more Number company thinks that there is still a need for configurations to send PSS/SSS and 5msCRS in synchronous new carrier wave.

Be unworthy of setting in new carrier wave Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) domain, original domain PDCCH may be used to transmission PDSCH.PHICH and PCFICH are not configured in new carrier wave.

New carrier wave divides into dependent operation and two kinds of independent operation, and above-mentioned is non-independent operation new carrier wave.For only The difference of vertical operation new carrier wave and dependent operation new carrier wave is: dependent runs NCT needs and at least one backward compatibility Carrier wave polymerization operation.General dependent operation NCT can only be the Scell of UE.Following description using new carrier wave as title, but Be new carrier wave it is practical be also carrier wave one kind, be intended merely to be different from backward compatibility carrier wave and a kind of appellation for using.

Preferably, the unicast service in the unicast resource in subframe is using extension CP transmission.Here unicast includes point-to-point unicast industry The system broadcast information of business and unicast is also possible to describe the UE D2D communication resource distribution of D2D business.The resource of the PMCH Information is the resource described for sending MBMS data, control signaling and the corresponding reference signal of MBMS business, wherein Specific send includes MTCH or MCCH, and wherein reference signal includes the reference signal for MBMS business.Preferably, the unicast CSI-RS is not allowed to configure in resource, because CSI-RS is to send in the period, if packet in the subframe of configuration CSI-RS in the period MBSFN and non-MBSFN are included, can be had an impact for the frequency domain position of CSI-RS, so that influencing the dispatching efficiency of PDSCH reduces.But It is when transmitting CSI-RS in the unicast resource, also possible, only base station needs to increase consideration when dispatching PDSCH Evade and dispatch situation hair of the CSI measurement for unicast service in non-MBSFN sub-frame is carried out using the unicast resource in MBSFN sub-frame It is raw.

The resource information of the unicast refers in description MBSFN sub-frame or is unicast allocated in the subframe of carrying PMCH Or time and/or frequency resource for unicast reservations, specifically include following one or more forms: 1) unicast allocated or it is pre- The PRB pair resource stayed.In this case it is that unicast uses first OFDM symbol that PRB pair, which is since subframe,.2) unicast Distribution 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 in subframe.For being located at latter 1 or 2 OFDM symbols mainly for avoiding and 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, Used relatively high power, if sending ePDCCH in first 1 or 2 OFDM symbols in the same subframe of adjacent area, each other it Between interference can be very big, so sending ePDCCH using 1 after subframe or 2 OFDM symbols.3) unicast allocated or it is reserved Frequency resource.In this case, frequency resource is configured for unicast, unicast service is only runed in the frequency resource of distribution.4) Unicast allocated or reserved sub-carrier resources.It in this case, is to be suitably for unicast to configure less resource, such as only transmit When a small amount of information, such as resource is not more than 12 subcarriers.5) the reserved bandwidth resources of the meeting of unicast allocated.Such case It is in unicast and the PMCH frequency division in the MBSFN subframe of agreement, is 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, so signal will do it superposition, so signal strength is very big, understand for close to the list on subcarrier It broadcasts business and forms interference, in order to avoid this interference, when the distribution of the resource information of the unicast proposed in this patent, there are unicasts When with the case where PMCH frequency division, the unicast resource distributed in the resource information of unicast includes protection band resource (also referred to as reserved money Source).Wherein in frequency direction of the protection band between unicast and PMCH.The size of protection band can be as network side and reception What end was arranged in advance.It can be the protection interval of subcarrier formal definition or the protection interval of PRB formal definition.When with subcarrier When the protection interval of formal definition, 5 or 6 subcarrier skies can be arranged and stayed between unicast and PMCH, or one PRB of agreement To by as protection band.Protection band resource is located in unicast and PMCH boundary, when PMCH and unicast are there are when multiple boundaries, that Each boundary has required protection band.For example, PMCH is located at the centre of bandwidth, unicast resource is located at both sides, just there is 2 at this time A boundary then needs 2 protection bands.The difference that unicast resource in the region MBSFN between cell in the carrier wave can configure 's.For example, two cells in the same region MBSFN, cell 1 can will be in unicast resource in MBSFN sub-frame and cell 2 Unicast resource in MBSFN sub-frame is different.Such case is conducive to the ePDCCH between adjacent area and cooperates, avoid each other due to The interference that resource is identical and generates.

The resource information of PMCH be describe MBSFN sub-frame in or carrying PMCH subframe in for PMCH distribution time and/ Or frequency resource, specifically include one or more forms of subordinate: 1) the PRB pair resource of PMCH distribution.In this case, MCE Need by the same region MBSFN in each cell for the region MBSFN PMCH resource allocation it is identical.2) PMCH is distributed OFDM symbol resource.3) frequency resource of PMCH distribution；4) sub-carrier resources of PMCH distribution；5) the bandwidth money of PMCH distribution Source.Optionally, protection band resource above-mentioned can also include by the PMCH resource that the resource information of PMCH is distributed, 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.When PMCH is according to PRB pair When being configured, the preferred PRB pair quantity for configuring PMCH is one: 6,15,25,50,75 and 100 in following 6.When When PMCH is configured according to subcarrier, the preferred number of subcarriers for configuring PMCH is following one: 72,90,150, 300,900,1200, or be 12 integral multiple.

The resource information of PMCH can also be provided by following mode, in the MBSFN subframe or carrying PMCH's In subframe other than the resource of unicast, remaining resource be all for PMCH distribution resource, wherein if in MBSFN sub-frame or Carrying in the subframe of PMCH has protection band, then unicast resource includes the protection band.The protection band is pre- as unit of subcarrier It stays.

Or when there is no protection band, when PMCH resource by unicast resource description to provide when, in the MBSFN subframe or It carries in the subframe of PMCH other than unicast resource, remaining resource is PMCH.

When unicast resource describes in subframe using PRB pair as unit, corresponding PMCH resource is also retouched as unit of PRB pair It states.

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 is description for sending MBMS data and the relevant letter of MBMS control The resource of order, 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 signaling.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 The influence that unicast service is received in MBSFN unicast resource or in non-MBSFN sub-frame, can be in PMCH for some highest version UE Unicast traffic in the resource of resource information instruction.Here influence is primarily referred to as influencing, old if not taking aforesaid way Version UE will be in blind examination in the resource without oneself data, to judge whether there is oneself data.Need exist for PMCH resource letter It is described the information of the resource practical use in breath, such as is really PMCH or is unicast service or MTC service or D2D industry Business etc..

Base station configures unicast and/or PMCH resource signaling, and sends.Unicast at this time and/or PMCH resource signaling are by base What station was autonomously generated, signaling, which is participated in, there is no MCE generates.The advantages of such case be base station do not need with MCE interaction, base station it Between can pass through X2 oral sex mutually mutual unicast and/or PMCH resource allocation conditions.Wherein specific unicast and/or PMCH resource The usage of signaling is same as mentioned above.

As the receiving end for receiving base station signaling, such as UE.Receiving end receives the system broadcast information or dedicated from carrier wave 1 Unicast and/or the resource information of PMCH are sent in channel, and are known in carrier wave 1 in MBSFN sub-frame according to the resource information The resource allocation conditions or receiving end of unicast and/or PMCH know the load with the carrier wave 1 pairing according to the resource information The resource allocation conditions of unicast and/or PMCH in wave 2 in MBSFN sub-frame.Wherein, unicast resource be used for transmission PDSCH, EPDCCH or ePHICH, PMCH resource are for MBMS data and control information.System broadcast information is preferably SIB2.

Wherein, the case where PMCH resource is there is also for unicast service or the use of other non-MBMS business, at this time PMCH resource Service type information comprising the actual use of PMCH resource in signaling.At this moment, PMCH resource is distributed for MBMS business, still Really transmit the resource of unicast service.

Receiving end is according to PMCH resource information, when UE determines that send in the PMCH resource is unicast service, then UE from Unicast service is received in the PMCH resource.UE can determine that the PMCH resource is practical hair by receiving PMCH resource information Unicast service or reality is sent to send MBMS business.UE also receives the unicast of adjacent cell and/or the resource information of PMCH, with Nearby region measurement or switching are carried out convenient for UE.
