Background technology
One, MBMS (Multimedia Broadcast/Multicast Service, multimedia broadcast-multicast service) technological overview.
The MBMS technology is used to the user in the wireless area that multimedia broadcasting and multicast services are provided.MBMS can carry out single cell transmission, also can carry out many cell transmission.Single cell transmission of MBMS refers to that MBMS only transmits in the coverage of a designated cell, do not support the merging that the MBMS from other residential quarters is transmitted; Many cell transmission of MBMS adopt MBSFN (Multicast Broadcast SingleFrequency Network, Multicast Broadcast Single Frequency Network) transmission means, that is: send simultaneously at one time the transmission means of identical content in a plurality of residential quarters with same frequency, UE (User Equipment, subscriber equipment) can merge the same-sign that a plurality of residential quarters send simultaneously.At LTE R9 (LTE version 9; LTE:Long Term Evolution, Long Term Evolution) in the version, single residential quarter and many cell transmission are all used the transmission means of MBSFN.
Two, MBMS channel architecture brief introduction.
In the LTE system, logic channel is MAC (Media Access Control, media access control) layer definition and interface upper-layer protocol, and logical channel type is used for distinguishing the type of data transmission service.Transmission channel is the interface that is used for the transmission of data that physical layer provides to high-rise (as: MAC layer), and the type of transmission channel defines according to transmission feature and the transmission means of data on physical layer.The logic channel relevant with the MBMS transmission mainly contains: BCCH (Broadcast Control Channel, Broadcast Control Channel), MCCH (Multicast Control Channel, multicast control channel) and MTCH (Multicast TrafficChannel, multicast service channel); Transmission channel mainly contains: MCH (Multicast Channel, Multicast Channel) and DL-SCH (Down-link Shared Channel, DSCH Downlink Shared Channel), and annotate: these channels are down channel; Physical channel mainly contains: PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) and PMCH (Physical Multicast Channel, Physical Multicast Channel).
Fig. 1 is logic channel and transmission channel mapping relations schematic diagram, and in LTE R8 standard, the mapping relations of logic channel and transmission channel are illustrated in figure 1 as:
BCCH is mapped on the BCH (Broadcast Channel, broadcast channel);
In single cell transmission of MBMS, MTCH and MCCH are mapped on the DL-SCH;
In many cell transmission of MBMS, MTCH and MCCH are mapped on the MCH;
In the version of LTE R9, MTCH and MCCH only are mapped on the MCH.
The Main Function of each channel is as follows:
(1)、BCCH(Broadcast?Control?Channel):
Broadcast Control Channel is used for network to the UE broadcast system information.For MBMS, carry the configuration information of MCCH among the BCCH, as: side-play amount, the number of sub frames that takies, RLC (the Radio Link Control of the repetition period of MCCH, beginning subframe, Radio Link control) UM (Un-acknowledgement Mode, Unacknowledged Mode) configuration etc., in order to make UE can find the resource location of MCCH, do not carry concrete MBMS business information among the BCCH.
(2)、MCCH(Multicast?Control?Channel):
Multicast control channel is a point-to-multipoint down channel, is used for network and transmits the relevant control information of this MBSFN zone MBMS to UE, and MCCH can be corresponding to one or more MTCH (that is: can carry a plurality of MTCH control information).The information that MCCH can comprise has: PMCH (Physical Multicast Channel, Physical Multicast Channel) or the configuration information of MCH, as: MSAP (MCH Subframe Allocation Pattern, MCH sub-frame allocation mode), MCS (Modulation andCoding Scheme, modulation coding mode), the MSAP occasion cycle (may I ask the inventor, how to translate?), MBMS RB (radio bearer) information (as: RB that within the modification cycle of a MCCH, provides), MBMS Session Start (MBMS meets beginning), MBMS Session Stop (MBMS meets and stops) etc.
(3)、MTCH(Multicast?Traffic?Channel):
The multicast service channel is a point-to-multipoint down channel, is used for network and sends concrete MBMS business datum to UE.
Network utilisation BCCH is to the configuration information of UE indication MCCH, and recycling MCCH provides the information of the MTCH of the concrete business of carrying to UE, thereby it is professional to make UE receive MBMS at MTCH.
(4)、MCH(Multicast?Channel):
Multicast Channel is the transmission channel for the MBMS transmission business, and MCCH and MTCH all can be mapped to the upper transmission of MCH.MBSFN zone can corresponding a plurality of MCH, and the MBSFN subframe that each MCH uses is indicated in its corresponding MSAP.UE will according to the indication of MSAP, receive the MBMS business of corresponding MCH in the subframe of correspondence.
Fig. 2 is schedule information indication schematic diagram, as shown in the figure, each MCH can have the dispatching cycle (or MSAP occasion cycle) of oneself, MCH dispatching cycle begin can at first transmit relevant control information, such as the dynamic scheduling information (such as Fig. 2) of this MCH in upper this dispatching cycle (or MSAP occasion cycle).Dynamic scheduling information was used to indicate in dispatching cycle (period) (or MSAP occasion cycle) at one or more MCH, and which subframe multiplexing each logic channel on same MCH uses respectively transmit.Because professional transmission is sudden, MCH some dispatching cycle or (or MSAPoccasion cycle) although some may occur by MSAP indication corresponding to this MCH, be not used to carry out the subframe that MBMS transmits, such as last two subframes among Fig. 2.
Three, MBSFN sub-frame allocation brief introduction.
The MBSFN subframe refers to the subframe that is used for the MBSFN transmission that system determines, the MBSFN subframe that system determines not only can be used for the MBMS transmission, can also other purposes, as: be used for network side base station and the internodal transmission of relay (relaying).At present, LTE system determined MBSFN sub-frame configuration of notice UE system in broadcast (SIB2, SystemInformation Block 2, system information block type 2).Which subframe in the MBSFN subframe really as the MBMS transmission, can directly be indicated by the MBSFN subframe configuration information among the BCCH, also can indicate in the corresponding MCCH in MBSFN zone.
In 3GPPTS 36.331v8.5.0 standard, the mode of the MBSFN sub-frame allocation that defines among the SIB2 is as follows:
MBSFN-SubframeConfig::= SEQUENCE{
radioframeAllocationPeriod ENUMERATED{n1,n2,n4,n8,n16,
n32},
radioframeAllocationOffset INTEGER(0..7),
subframeAllocation CHOICE{
oneFrame BIT?STRING(SIZE(6)),
fourFrames BIT?STRING(SIZE(24))
}
MBSFN is divided into two ranks: Radio Frame (radio frames) and Sub Frame (subframe).
1)、Radio?Frame。
Adopt radio frames to distribute the mode of Period (cycle) and offset (side-play amount) to represent, the MBSFN radio frames will appear in the position of satisfying following formula at SFN (system frame number, System Frame Number):
SFN mod radioFrameAllocationPeriod=radioFrameAllocationOffset (radio frame number mod radio frames assignment period=radio frames allocation offsets amount)
2)、Sub?Frame。
What sub-frame allocation was followed is bitmap (bit mapping) mode, has specifically two kinds:
(1) single radio frames bitmap.
oneFrame BIT?STRING(SIZE(6))
(2) four continuous radio frames bitmap.
fourFrames BIT?STRING(SIZE(24))
For FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)), MBSFN subframe available in each radio frames is: #1, #2, #3, #6, #7, #8, and corresponding to 6 bits of bitmap.
For TDD (Time Division Duplex, time division duplex), MBSFN subframe available in each radio frames is: #3, #4, #7, #8, #9, corresponding to front 5 bits of bitmap, last 1 bit of bitmap does not use.In addition, for TDD, sub-frame of uplink can not be assigned to the MBSFN subframe.
When subframe is assigned as four continuous radio frames bitmap, according to 1) in radio frames distribute SFN that formula calculates to be the original position of these four radio frames.
Four, MSAP indicative abstract.
After UE receives the MBSFN sub-frame allocation mode that network side sends, if UE does not receive the MBMS business, UE information on the MBSFN subframe determined of monitoring system not so; If it is professional that UE receives MBMS, UE need to know the business of desired reception in which MBSFN subframe sends so.In the current standard, the logic channel MCCH of MBMS transmission control information and business information and MTCH are mapped on the MCH, and the shared subframe of MCH is specified by its corresponding MSAP (MCH sub-frame allocation pattern).Therefore, UE need to know the business that wish to receive the sub-frame allocation pattern of corresponding MCH come corresponding subframe is received.
Fig. 3 is for using MSAP indicating mode schematic diagram, and Fig. 4 is that MBSFN sub-frame allocation mode makes up schematic diagram, and Fig. 5 is the schematic diagram with the MCH indication, below in conjunction with the indicating mode of description of drawings MSAP.The current indicating mode of not yet specifically determining MSAP, but several possible mode is as follows:
1), a plurality of MBSFN sub-frame allocation patterns of definition among the SIB2, certain employed MBSFN subframe in MBSFN zone can be the combination (Fig. 3) of several MBSFN sub-frame allocation patterns, and the corresponding MBSFN subframe of certain MCH (that is: MSAP) is indicated (Fig. 4) by the specific schedule parameter (as: time started) of corresponding public dispatching cycle of MCH and each MCH in this MBSFN zone in this MBSFN zone.
The subframe that the horizontal line shape represents among Fig. 4 is respectively the shared subframe of MBSFN sub-frame allocation pattern 1 and MBSFN sub-frame allocation pattern 2, latticed expression be the subframe that can be configured to the MBSFN subframe in corresponding ten subframes of a radio frames, above the subframe that middle horizontal line shape subframe is MBSFN sub-frame allocation pattern 1 correspondence, below the subframe that middle horizontal line shape subframe is MBSFN sub-frame allocation pattern 2 correspondences.
Be to comprise two MCH in the MBSFN zone shown in Fig. 5, be 320ms the dispatching cycle of MCH 1, the dispatching cycle of MCH 2 be 640ms, latticed expression be the dynamic scheduling information of MCH 1, oblique line shape represents is the dynamic scheduling information of MCH 2.Define public dispatching cycle in this zone and be 320ms (that is: adopt dispatching cycle among each MCH minimum value), and the beginning subframe of MCH, can find out so from the graph in each common period, the subframe of MCH 1 correspondence is for beginning regional employed subframe to MCH 2 beginning subframes this MBSFN of forward all from this common period, the subframe of MCH 2 correspondences is all these employed subframes in MBSFN zone that backward finish to common period from MCH 2 beginning subframes.
On the basis of the MBSFN sub-frame allocation mode that 2), in SIB2, defines (certain employed MBSFN subframe in MBSFN zone can be the combination of several MBSFN sub-frame allocation modes), further indicate which subframe (such as Fig. 3) in the corresponding MBSFN subframe of certain MCH, as: can adopt the cycle mode of (optional)+bias+bitmap (perhaps increment (delta) bitmap, perhaps MCH number of sub frames) to indicate.
The deficiencies in the prior art are: when occurring not by the subframe of (MBMS transmission) use in the corresponding MBSFN subframe of certain MCH of system's indication, because the user who carries out unicast data transmission does not generally monitor the information on these subframes, therefore, can not adopt these subframes to send unicast data, the resource on these subframes will be wasted.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
The inventor notices in the invention process, and in the LTE system, the user who does not receive the MBMS transmission does not go to monitor the MBMS schedule information, in addition, also just monitors the schedule information on the professional corresponding MCH of receiving even receive the user of MBMS business.Therefore, when having occurred not by the subframe of MBMS transmission use on some MCH, even if these subframes can be used for sending other non-MBMS data, because common unicast user acquiescence is not monitor the MBSFN subframe, therefore above-mentioned user and do not know which the MBSFN subframe in which section period can transmit unicast data, these subframes can not be used for sending data for these users.Fig. 6 is MBSFN subframe schematic diagram corresponding to MCH, as shown in Figure 6, the subframe of latticed expression is the corresponding subframe of certain MCH, in certain dispatching cycle, only have two corresponding in the radio frames 0 subframes to be used to the MBSFN transmission, three idle subframes in the radio frames 1 then can be used for sending non-MBMS data.
For being can be used in to unicast user, these MBSFN subframes that are not used transmit non-MBMS data, improve the utilance of Radio Resource, a kind of sending method of schedule information has been proposed, in the method can be with the resource location information notification UE of the idle MBSFN subframe on the MCH, so that UE can be known the resource location of idle MBSFN subframe, thereby can between UE and network side, can utilize these idle MBSFN sub-frame resources the transmission of datas.Therefore, know that idle MBSFN sub-frame resources position just can take full advantage of the resource of idle MBSFN subframe as long as can make UE and network side, then be to make both sides know the resource situation of idle MBSFN subframe by schedule information in the scheme that provides in the embodiment of the invention, the below will describe transmission and the reception of schedule information.
In the declarative procedure below, PMCH does not also have clear and definite regulation in agreement at present, because MCH is close with the PMCH operation principle, therefore will mainly describe as an example of MCH example among the embodiment, obviously, after PMCH determined, the scheme in the embodiment of the invention also can be implemented in PMCH.
Fig. 7 is the sending method implementing procedure schematic diagram of schedule information, as shown in the figure, can comprise the steps: when sending schedule information
Step 701, determine idle MCH or PMCH, have idle MBSFN subframe on described idle MCH or the PMCH;
Wherein idle MBSFN subframe refers to not have the MBSFN subframe of actual bearer MBMS data when MBMS transmits;
Step 702, definite indication MCH or PMCH, described indication MCH or PMCH and idle MCH or PMCH are in same MBSFN zone;
Step 703, in schedule information corresponding to described indication MCH or PMCH, carry indication information, described indication information comprises: whether MCH or PMCH in the indication MBSFN zone are described idle MCH or PMCH, and/or indicate the resource location of the idle MBSFN subframe on described idle MCH or the PMCH;
Step 704, send described schedule information at described indication MCH or PMCH.
Accordingly, also provide a kind of method of reseptance of schedule information in the embodiment of the invention, the below describes.
Need to prove, in to implementation of the present invention, will describe from sending, receiving simultaneously, thereby be convenient to understand on the whole enforcement of the present invention, also be convenient to simultaneously to illustrate the corresponding reception ﹠ disposal process after the transmission, certainly, this is obviously and do not mean that and send and receive and must implement simultaneously.
Fig. 8 is the method for reseptance implementing procedure schematic diagram of schedule information, as shown in the figure, can comprise the steps: in the schedule information receiving course
Step 801, receive the schedule information of having carried indication information at indication MCH or PMCH, described indication information comprises: whether MCH or PMCH in the indication MBSFN zone are described idle MCH or PMCH, and/or indicate the resource location of the idle MBSFN subframe on described idle MCH or the PMCH, described indication MCH or PMCH and idle MCH or PMCH to be in same MBSFN zone;
Step 802, determine according to the indication information in the described schedule information whether MCH or PMCH in the MBSFN zone are idle MCH or PMCH, and/or indicate the resource location of the idle MBSFN subframe on idle MCH or the PMCH.
The below describes concrete send and receive implementation process.
This programme purpose is: suppose to exist on the MCH idle MBSFN subframe, then the MCH at other indicates, during indication, comprise two contents: indicate the resource location that whether has idle MBSFN subframe, idle MBSFN subframe on described idle MCH or the PMCH, the two can be indicated simultaneously, also can be only with wherein one of indication, the below separately describes.
In the implementation, on the described idle MCH of indication or PMCH, whether exist in the enforcement of idle MBSFN subframe, each MCH may possess two kinds of attributes simultaneously, namely, available free MBSFN subframe on himself, it also can be selected on other MCH of indication whether have idle subframe simultaneously, further, owing to need not when a MCH is idle MCH self be indicated in implementing, therefore can make idle MCH and indication MCH is not same MCH yet.For example: suppose in a MBSFN zone, to exist MCH to be respectively: MCH1, MCH 2, MCH 3, MCH 4, so, if equal available free MBSFN subframe on MCH1, MCH 2, MCH 3, the MCH 4, so, can indicate MCH 2, MCH 3, MCH 4 by MCH1, perhaps, MCH1 indication MCH 2, MCH 3 indication MCH 4, perhaps, MCH1 indication MCH 2 and/or MCH 3 and/or MCH 4 etc., need not MCH1 indication MCH1, MCH 2 indication MCH2, MCH 3 indication MCH3, MCH 4 indication MCH4, still, obviously MCH1 also can indicate self whether available free subframe.
What also need additional description is, be not so long as have the idle MCH of idle MBSFN subframe and just necessarily need to indicate to UE, such as equal available free MBSFN subframe on MCH1, MCH 2, MCH 3, the MCH 4, but can only indicate available free MBSFN subframe on MCH 3, the MCH 4 to UE on certain MCH in force, although and also available free MBSFN subframe on MCH1, the MCH 2, but need not the indication to UE, can indicate according to the actual needs of network when specifically indicating.
After determining indication MCH and needing the idle MCH of indication, only need on the idle MCH of schedule information indicating corresponding to indication MCH, whether to exist idle MBSFN subframe can make UE know idle MBSFN subframe situation on the MCH.
That is, in dynamic scheduling information corresponding to each MCH, except the corresponding relation that can indicate MBSFN subframe corresponding to this MCH and each logic channel, can also carry the information of the upper idle MBSFN subframe of other MCH.In an embodiment, so obvious such as the idle MBSFN subframe situation of need on other MCH of schedule information corresponding to MCH indication, other MCH here can for:
1, among all MCH of this MBSFN zone correspondence, the every other MCH except current MCH;
2, among all MCH of this MBSFN zone correspondence, the MCH of the idle MBSFN subframe of every other existence except current MCH;
3, among all MCH corresponding to this MBSFN zone, there is some MCH among the MCH of idle MBSFN subframe in other except current MCH.
In the enforcement, in the process of transmitting of schedule information, when whether the MCH in indication MBSFN zone or PMCH are described idle MCH or PMCH, can adopt the bitmap mode to indicate.
Accordingly, in the receiving course of schedule information, when determining according to the indication in the described schedule information whether MCH in the MBSFN zone or PMCH are described idle MCH or PMCH, can determine according to bitmap.
Concrete, the MCH in indication MBSFN zone or PMCH when whether being described idle MCH or PMCH can be:
Adopt the mode of bitmap to indicate for other MCH, there is idle subframe in 1 expression, and there is not idle subframe in 0 expression.If there are 5 MCH in certain MBSFN zone, the corresponding MCH 1 of this MCH, so bitmap 01100 expression: there is not idle MBSFN subframe in this MCH, and there are idle subframe in MCH 2 and MCH 3.Above-mentioned bitmap also can not indicate the MCH at place whether to have idle MBSFN subframe.When being in connection status and receiving the UE of MBMS business, when finding there is idle subframe on the MCH, can monitor in idle subframe the schedule information of non-MBMS transmission.If having the MCH of idle subframe is not the current MCH that is receiving the MBMS business, UE goes to read schedule information corresponding to the MCH that has idle subframe determining concrete idle subframe position so, thereby can carry out non-MBMS data transfer or transmission in the idle subframe of correspondence.
In the enforcement, in the process of transmitting of schedule information, comprise in the indication information whether MCH or PMCH in the indication MBSFN zone are described idle MCH or PMCH, the resource location that can also comprise the idle MBSFN subframe on the idle MCH of indication or the PMCH, namely, when there are idle MBSFN subframe in idle MCH or PMCH, can be at the resource location of the idle MBSFN subframe of schedule information indicating.
Accordingly, in the receiving course of schedule information, when there are idle MBSFN subframe in idle MCH or PMCH, can determine according to schedule information the resource location of idle MBSFN subframe.
Although the concrete indicating mode of current multidate information is not yet specifically determined, but within the dispatching cycle (or MSAP occasion cycle) of MCH, the MBSFN subframe that is not used (that is: idle MBSFN subframe) or clearly indication in dynamic scheduling information, or also can from dynamic scheduling information, derive and draw.Therefore in implementing, in the process of transmitting of schedule information, when the resource location of the idle MBSFN subframe of indication, can comprise as an example of MCH example:
Indicate the resource location of idle MBSFN subframe by MSAP, dispatching cycle and the dynamic scheduling information of MCH;
Or, indicate the resource location of idle MBSFN subframe by MSAP, MSAP occasion cycle and the dynamic scheduling information of MCH;
Or, the beginning of MSAP, dispatching cycle and idle MBSFN subframe by MCH and/or finish the resource location that subframe is indicated idle MBSFN subframe;
Or, the beginning of MSAP, MSAP occasion cycle and idle MBSFN subframe by MCH and/or finish the resource location that subframe is indicated idle MBSFN subframe;
Or the beginning subframe of MSAP, MSAP occasion cycle and idle MBSFN subframe by MCH or PMCH is indicated the resource location of idle MBSFN subframe, and subframe or the radio frames quantity monitored;
Or the beginning subframe of MSAP, MSAP occasion cycle and idle MBSFN subframe by MCH or PMCH is indicated the resource location of idle MBSFN subframe.
Accordingly, when determining the resource location of idle MBSFN subframe, can comprise as an example of MCH example:
Determine the resource location of idle MBSFN subframe according to MSAP, dispatching cycle and the dynamic scheduling information of MCH;
Or, determine the resource location of idle MBSFN subframe according to MSAP, MSAP occasion cycle and the dynamic scheduling information of MCH;
Or, according to the beginning of MSAP, dispatching cycle and the idle MBSFN subframe of MCH and/or finish the resource location that subframe is determined idle MBSFN subframe;
Or, according to the beginning of MSAP, MSAP occasion cycle and the idle MBSFN subframe of MCH and/or finish the resource location that subframe is determined idle MBSFN subframe;
Or, the resource location of the idle MBSFN subframe of the beginning subframe indication of MSAP, MSAP occasion cycle and idle MBSFN subframe by MCH or PMCH, and subframe or the radio frames quantity monitored, determine the resource location of idle MBSFN subframe and monitor quantity;
Or the resource location of the idle MBSFN subframe of the beginning subframe indication of MSAP, MSAP occasion cycle and idle MBSFN subframe by MCH or PMCH is determined the resource location of idle MBSFN subframe.
In the implementation, in the beginning that utilizes idle MBSFN subframe and/or when finishing subframe and determining the resource location of idle MBSFN subframe, finish subframe and not necessarily will occur.If namely giving tacit consent to the length of the idle subframe that a schedule information comprises is exactly a dispatching cycle, when finish dispatching cycle, to give tacit consent to idle subframe and finish so, that is: implicit expression finishes.
Indicate the resource location of idle MBSFN subframe in the beginning subframe of MSAP, MSAP occasion cycle and idle MBSFN subframe by MCH or PMCH, and when the subframe of monitoring or radio frames quantity, monitor sub-frame number and refer to that user terminal when the quantity of the idle MBSFN subframe of monitoring equals to monitor sub-frame number, stops to monitor idle MBSFN subframe; The monitoring wireless number of frames refers to that user terminal when the quantity of the radio frames of monitoring idle MBSFN subframe place equals described monitoring wireless number of frames, stops to monitor idle MBSFN subframe.
When the beginning subframe of MSAP, MSAP occasion cycle and idle MBSFN subframe by MCH or PMCH was indicated the resource location of idle MBSFN subframe, this mode stopped when finish dispatching cycle in acquiescence.
In the implementation, the indication exist idle subframe MCH idle sub-frame information mode can for:
Provide MSAP, dispatching cycle (or MSAP occasion cycle) and the dynamic scheduling information in corresponding dispatching cycle of corresponding MCH, can know that according to these information UE those are idle subframes in the MBSFN subframe on the corresponding MCH;
Provide beginning (and end) subframe of MSAP, dispatching cycle (or MSAP occasion cycle) and the idle subframe of corresponding MCH.Fig. 9 is the resource location indication schematic diagram of idle MBSFN subframe, as shown in Figure 9, the subframe that can be used for the MBSFN transmission for system definition that the horizontal line shape represents, what the vertical line shape represented is the corresponding MBSFN subframe of certain MCH, latticed then is the MBSFN subframe of this MCH free time.
In the enforcement, in the process of transmitting of schedule information, when the beginning of indicating the idle subframe of MBSFN and/or end subframe, can comprise:
Beginning and/or the index indication of the corresponding MCH of end subframe in dispatching cycle by the idle subframe of MBSFN;
Or, by beginning and/or corresponding radio frame number and the indication of the subframe index in radio frames thereof of end subframe of the idle subframe of MBSFN;
Or, by beginning and/or the index indication of the corresponding MCH of end subframe in dispatching cycle of the busy subframe of MBSFN;
Or, by beginning and/or corresponding radio frame number and the indication of the subframe index in radio frames thereof of end subframe of the busy subframe of MBSFN.
Accordingly, in the receiving course of schedule information, when the beginning of determining the idle subframe of MBSFN and/or end subframe, can comprise:
Beginning and/or the index of the corresponding MCH of end subframe in dispatching cycle according to the idle subframe of MBSFN are determined;
Or, determine by beginning and/or corresponding radio frame number and the subframe index in radio frames thereof of end subframe of the idle subframe of MBSFN;
Or, determine according to beginning and/or the index of the corresponding MCH of end subframe in dispatching cycle of the busy subframe of MBSFN;
Or, determine by beginning and/or corresponding radio frame number and the subframe index in radio frames thereof of end subframe of the busy subframe of MBSFN.
In the implementation, in the mode of beginning (and end) subframe of the idle subframe of indication MBSFN can be:
1), by beginning (and end) idle subframe to providing by the index of MCH in dispatching cycle.Take Fig. 9 as example, to establish radio frames 1 and be the beginning radio frames of certain dispatching cycle, the index of the idle subframe that begins so is 12, the index of the idle subframe of end is 15.If idle subframe acquiescence stops when finish dispatching cycle, the idle subframe index that so only need provide beginning gets final product.
2), the beginning by the idle subframe of MBSFN and/or finish radio frame number corresponding to subframe and the subframe index in radio frames provides.Take Fig. 9 as example, to establish radio frames 1 and be the beginning radio frames of certain dispatching cycle, the radio frame number of the correspondence of the idle subframe that begins so is 4, the idle subframe of beginning corresponding subframe index in radio frames 4 is 2; The radio frame number of the correspondence of the idle subframe that finishes is 5, and the idle subframe of end corresponding subframe numbers in radio frames 5 is 3, so directly just can indicate the position of idle subframe by index 4,2,5,3.
3), the beginning by providing busy subframe (and end) subframe is to providing by the index of MCH in dispatching cycle.
4), the beginning by the busy subframe of MBSFN and/or finish radio frame number corresponding to subframe and the subframe index in radio frames provides.
Can utilize idle MBSFN subframe the transmission of data between network side and the UE in order to make, can also make by the information reporting of UE network side understand the MCH operating position of UE in the enforcement, namely, network side can determine UE can obtain the idle sub-frame information on which MCH according to the information that UE reports, and then carries out the professional reception/transmission of non-MBMS at these idle subframe scheduling UE.
In then implementing, in the process of transmitting of schedule information, can further include:
The MBMS business information that the MBMS accepting state that reports according to UE or UE report is identified for transmitting the idle MBSFN subframe of UE data, comprises MCH that UE monitors or the information of PMCH in the described accepting state.
Accordingly, in the receiving course of schedule information, can further include:
UE reports the MBMS accepting state, and described accepting state is used for determining for network side the idle MBSFN subframe of transmission UE data, comprises MCH that UE monitors or the information of PMCH in the described accepting state;
Or UE reports the MBMS business information, and described business information is used for determining for network side the idle MBSFN subframe of transmission UE data.
Concrete, UE reports the MBMS accepting state, has comprised the MCH information that UE monitors in the MBMS accepting state, then can comprise:
Report MCH that UE monitors or the index of PMCH, directly report the index of the MCH that UE monitors under this mode;
Or MCH or PMCH so that the form of bitmap reports UE to be monitored can adopt the form of bitmap to report under this mode, as: this MBSFN zone one co-exists in 3 MCH, but UE only monitors second MCH, and the bitmap that reports so can be 010.
In the implementation, UE reports the MBMS business information, then can comprise:
UE reports the professional corresponding call number of MBMS, as: have 5 business in this MBSFN zone, current UE is receiving the 3rd business, so just professional call number 3 is reported;
Or UE reports the professional corresponding Logic Channel Identifier (LCID) of MBMS;
Or UE adopts the form of bitmap to report MBMS professional, as: have 5 business in this MBSFN zone, current UE is receiving the 3rd business, and the bitmap that reports so can be 00100.
In the implementation, UE can pass through RRC (Radio Resource Control, Radio Resource control) signaling or MAC CE (Medium Access Control Control Element, media access control layer control unit) report the MBMS accepting state or report the MBMS business information.
Based on same inventive concept, a kind of receive-transmit system, network equipment, subscriber equipment of schedule information also are provided in the embodiment of the invention, because the principle that these equipment are dealt with problems is similar to the method for reseptance of a kind of sending method of schedule information, a kind of schedule information, therefore the enforcement of these equipment can referring to the enforcement of method, repeat part and not give unnecessary details.
