Description
Technical field
The present invention relates to field of wireless communication, particularly the resource allocation methods of Physical Multicast Channel (PMCH, Physical Multicast Channel) and device in Long Term Evolution (LTE, Long TermEvolution) system.
Background technology
2005,3GPP (3rd Generation Partnership Project, third generation partner program) start LTE (Long Term evolution, Long Term Evolution) working group studied, the next generation network of the 3.9G (3G of improvement) of research and the evolution of design G mobile communication.
In order to effectively utilize mobile network resource, 3GPP proposes MBMS (MBMS, Multimedia Broadcast Multicast Service, MBMS), a data source is provided to send the point-to-multipoint service of data to multiple user in a mobile network, realize network resources locating, improve the utilance of Internet resources, especially valuable interface resource of eating dishes without rice or wine.In the lte networks, the MBMS technology of research is called E-MBMS (Evolved MBMS, the multimedia broadcast multi-broadcasting business of improvement).
In LTE FDD (Frequency Division Duplexing (FDD)) and LTE TDD (time division duplex), on mixed carrier, i.e. existing multicast (multicast) business on this carrier wave, also unicast (clean culture) business is had, now radio frames is divided into MBSFN frame (MBMS single frequency network wireless frame, for carrying mulicast business, as: broadcasting service) and None-MBSFN frame (non-MBSFN frame, namely unicast frame, Unicast frame, for carrying unicast business, as: normal speech business); Part subframe in MBSFN frame adopts MBSFN radiation pattern, that is: the subframe in each MBSFN frame is divided into again MBSFN subframe (MBSFN sub-frame) and Non-MBSFNsubframe (non-MBSFN sub-frame, that is: unicast subframe), and None-MBSFN frame does not adopt MBSFN radiation pattern, and adopt unicast radiation pattern.
As Fig. 1, system broadcast message configures MBSFN physical resource, within the cycle of a 320ms, namely have 32 radio frames, and each radio frames comprises 10 subframes, always have 320 subframes, according to the requirement of measuring, need which subframe indicating 320 subframes to be MBSFN subframe.
In the lte networks, no matter be FDD or TDD, no matter whether receive MBMS, UE (user equipment, subscriber equipment or title terminal) all need to know that each radio frames is MBSFN frame, also need to know whether each subframe in each MBSFN frame have employed MBSFN, that is: UE needs to know that each subframe is MBSFN subframe or Non-MBSFN subframe, so that UE is in the enterprising measurement of each subframe and channel estimating.Therefore, E-UTRAN (Evolved UTRAN, the universal terrestrial access network that Evolved Universal Terrestrial Radio Access Network improves) need to pass through system broadcast message, the above-mentioned message notice of each radio frames and subframe is also needed to know whether each radio frames and each subframe are that MBSFN frame and MBSFNsubframe is to carry out measurement and the channel estimating of each subframe to UE, UE.
According to current disclosed technology, if a radio frames is wherein containing several MBSFN sub-frame, this radio frames is called MBSFN frame.In order to save the expense in system broadcast message, System information block 2 (the SIB2 of the system broadcast message of a community, system information block2) on, by information unit MBSFN-SubframeConfiguration, radio frames and wireless sub-frame two levels are adopted to indicate the wireless sub-frame of which radio frames to be MBSFN sub-frame.On SIB2, now comprise the configuration of one or more MBSFN sub-frame, the configuration of each MBSFN sub-frame is called a SAP (subframeAllocation Pattern, Subframe Allocation Pattern).Each SAP configuration packet contains:
1) radio frame level: radio frame level adopts the mode of cycle and skew, and indicate which radio frames within a time cycle to be the radio frames being configured with MBSFN sub-frame, the radio frames namely meeting following formula is MBSFN frame.
SFN mod radioFrameAllocationPeriod=radioFrameAllocationOffset (formula 1)
Wherein: SFN is the frame number of radio frames;
RadioFrameAllocationPeriod is the assignment period of radio frames;
RadioFrameAllocationOffset is the allocation offsets of radio frames;
2) wireless sub-frame level: adopt BITMAP (bit mapping, also referred to as bitmap) 10 subframe middle fingers of each MBSFNframe bright which be MBSFN subframe, that is: on subframe level, the allocation model being defined in the MBSFN subframe in these MBSFN frame is identical, that is: the number of the MBSFN subframe be assigned with in each MBSFN frame is identical with subframe numbering, and (10 subframes of each radio frames are numbered: #0, #1, ..., #9), as shown in Figure 1, radio frames #0, #1, #2 is MBSFN frame, MBSFN subframe in these three frames configures identical, be subframe #8.Due to the subframe #0 of FDD, #4, #5 and #9, the subframe #0 of TDD, #1, #2, #5, #6 can not be configured to MBSFN sub-frame regularly, so the Bitmap of the allocation model of wireless sub-frame adopts 6bit, that is: { Bit0, Bit1, Bit2, Bit3, Bit4, Bit5} represent.The wherein corresponding subframe #8 of FDD, Bit0 corresponding subframe #1, Bit1 corresponding subframe #2, Bit2 corresponding subframe #3, Bit3 corresponding subframe #6, Bit4 corresponding subframe #7, Bit5; TDD, Bit0 corresponding subframe #3, Bit1 corresponding subframe #4, Bit2 corresponding subframe #7, Bit3 corresponding subframe #8, Bit4 corresponding subframe #9, Bit5 retain without actual use.When certain or some Bit are set to " 1 ", then represent that the subframe corresponding to this Bit is configured to MBSFN sub-frame.As shown in table 1.
Table 1: adopt Bitmap to represent the allocation model of MBSFN sub-frame
| Bit number | Bit0 | Bit1 | Bit2 | Bit3 | Bit4 | Bit5 |
| FDD | Subframe #1 | Subframe #2 | Subframe #3 | Subframe #6 | Subframe #7 | Subframe #8 |
| TDD | Subframe #3 | Subframe #4 | Subframe #7 | Subframe #8 | Subframe #9 | Meaningless |
Citing: certain SAP sub-frame configuration pattern=111100, for FDD, represents that subframe #1, #2, #3, #6 are configured to MBSFN sub-frame, for TDD, represents that subframe #3, #4, #7, #8 are configured to MBSFN frame.
In order to increase configuration flexibility, above-mentioned Subframe Allocation Pattern can also adopt the method for salary distribution of 4 continuous radio frames, wireless sub-frame rank represents { Bit0 with 24 bit, Bit1, ... .Bit23}, wherein Bit0-Bit5 indicates the MBSFN sub-frame of the 1st radio frames, and Bit6-Bit11 indicates the MBSFN sub-frame of the 2nd radio frames, Bit12-Bit17 indicates the MBSFN sub-frame of the 3rd radio frames, and Bit18-Bit23 indicates the MBSFN sub-frame of the 4th radio frames.
In existing LTE technology, the logic channel of MBMS is MTCH, the session of the corresponding MBMS of each MTCH.Many MTCH channel can be mapped to same transmission channel PMCH, and a transmission or many PMCH channel mappings are to arriving same physical channel PMCH, and a PMCH channel is made up of one group of MBSFN sub-frame.
In existing LTE technology, introduce the concept of MBSFN area, in a MBSFN area (MBMS single-frequency network area), MBMS adopts MBSFN single frequency network mode to send, in same MBSFN area, different districts adopts the duplicate physical signalling of the transmission of identical resource, content and time synchronized, to realize the receiving gain of receiving terminal (UE).MTCH is mapped to MCH and then is mapped to PMCH, can MBSFN mode send.Can configure one or more PMCH in a MBSFN area, a PMCH can carry one or more MCH, and preferably, a PMCH carries a MCH channel.
Logic channel MCCH channel is multicast control channel, and MCCH carries the configuration information of every bar MCH/PMCH in one or more MBSFNArea, comprises the MBSFN sub-frame configuration, Modulation and Coding Scheme etc. of each PMCH channel configuration.
Because the quality of service requirement of MBMS is different, different types of service needs different dispatching cycles, or be called MSAP occasion (MBSFN sub-frame allocation model opportunity), this parameter specifies the cycle that a business is scheduled at wave point.To the business of latency sensitive, need to configure smaller dispatching cycle, and longer dispatching cycle is conducive to the change of level and smooth service rate.That is, in a MBSFN region, the configuration needs of multiple business dispatching cycle may be there is.
In the resource allocation method of existing Physical Multicast Channel, a MBSFN region can configure many MCH, and the corresponding physics PMCH channel of each MCH, every bar PMCH is configured in a MSAP occasion and configures one group of MBSFN sub-frame resource.Belong to the MBSFN sub-frame set in this MBSFN region of the MBSFN sub-frame resource composition of many PMCH in same MBSFN region.This MBSFN sub-frame set configures in the following way: specify the MBSFN sub-frame of one or more SAP in SIB2 to form this MBSFN sub-frame set, a list item of wherein MBSFN-SubframeConfiguration list in the corresponding SIB2 of each SAP.When configuring the PMCH of different dispatching cycle, the method selects be resource allocation cycle less dispatching cycle, and in this resource allocation cycle, for each PMCH distributes different subframe sections.Example as shown in Figure 2, dispatching cycle is one group of business SG-1 of 320ms, and dispatching cycle is one group of business SG-2 of 640ms, and dispatching cycle is one group of business SG-3 of 640ms.SG-1 will be mapped to PMCH1, and its MSAP occasion is long will be carried on PMCH2 for 320ms, SG-2, and its MSAP occasion is long is carried on PMCH3 for 640ms, SG-3, and its MSAP occasion is long is 640ms.Meanwhile, resource allocation cycle is chosen as 320ms, PMCH1 and PMCH2, PMCH3 carry out Resourse Distribute respectively in each 320ms.Because resource allocation cycle is 320ms, so PMCH2 and PMCH3 is within the dispatching cycle of a 640ms, its resource is divided into two parts respectively, lay respectively in former and later two resource allocation cycle, and the MBSFN sub-frame number of distributing for PMCH2 or PMCH3 in former and later two 320ms is identical.
So just there is problem below:
1. because the resource of PMCH2 and PMCH3 is divided into two parts by average, MBSFN sub-frame number so shared by PMCH2 or PMCH3 must be even number, if the MBSFN sub-frame number required for the resource of PMCH2 or PMCH3 is odd number, the waste of a MBSFN sub-frame will be caused.
2. receive from the angle of UE, the resource of PMCH2 and PMCH3 has been divided into two parts, this means if UE needs to receive all business of this PMCH, and UE will be divided into and receiving for twice, in other words, the continuity of the resource of PMCH2 and PMCH3 within its dispatching cycle is good not.
