Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
In the LTE communication system, residential quarter may belong to a plurality of MBSFN zone simultaneously, because there is own MCCH in each MBSFN zone, therefore when the regional generation of the MBSFN in a residential quarter is overlapping, can have a plurality of MCCH.
Fig. 1 is the schematic flow sheet of an embodiment of signal processing method of the present invention, and as shown in Figure 1, the present embodiment comprises the steps:
The signaling indication bit of step 102, the described Physical Downlink Control Channel of transmission.
Signaling indication bit in the embodiment of the present invention, be specifically as follows the individual bit of N (N is positive integer) of setting in PDCCH, N depends on MCCH channel number corresponding to overlapping MBSFN zone number or MBSFN zone that can support residential quarter, MBSFN place.
The signal processing method that the embodiment of the present invention provides, the information that whether changes according to the state of the System information block of the multicast control channel information that changes or multimedia broadcast-multicast service arranges the bit status of the signaling indication bit of PDCCH, after receiving PDCCH, UE can know that the signaling of MBMS changes information by the signaling indication bit, make UE needn't receive one by one the signaling message of MBMS, therefore reduced the complexity that UE detects.
The technical scheme of embodiment for a more clear understanding of the present invention, the embodiment of the present invention only have fixing number of bits take the signaling indication bit and describe as example, but fixing number of bits does not consist of the restriction to the embodiment of the present invention.In addition, the PDCCH in the embodiment of the present invention is specifically as follows the PDCCH of form 1C, is perhaps the PDCCH of form 1A; Signaling changes information can be Downlink Control Information (Downlink Control Information, abbreviation: change information DCI).
Fig. 2 is the schematic flow sheet of another embodiment of signal processing method of the present invention, and as shown in Figure 2, the present embodiment comprises:
If step 202 signaling change information is the change information of a plurality of MCCH, the bit status of the signaling indication bit of PDCCH is set according to the change information of a plurality of MCCH, makes UE obtain according to bit status the MCCH that in a plurality of MCCH, state information changes when receiving PDCCH.
In above-mentioned steps 202, particularly, the change information of MCCH can be change state information and/or the service reason indication information of MCCH and/or the change type of service indication information of MCCH of MCCH.
If signaling change information is the change information of MCCH, the bit status of the signaling indication bit of PDCCH is set according to the change information of MCCH, make UE obtain the change information of MCCH according to bit status when receiving PDCCH.
Particularly, if the change information of MCCH is the change state information of MCCH, when the MBSFN zone overlaps in same residential quarter, be that a plurality of MBSFN are arranged in same residential quarter, the change state information of the MCCH that the base station is corresponding according to a plurality of MBSFN arranges the bit status of this signaling indication bit, makes UE obtain according to this signaling indication bit the change state information that is specially MCCH corresponding to which or which MBSFN in a plurality of MBSFN when receiving PDCCH and changes.
More specifically, suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, if the base station gets the change state information that the signaling change information of MBMS is specially MCCH, the bit status of signaling indication bit of 8 bits of the PDCCH of form 1C type is set according to the change state information of this MCCH, therefore when a plurality of MBSFN region overlappings are in same residential quarter, according to the control information change of which or which MCCH in signaling indication bit a plurality of MBSFN of indication overlapping region of this 8 bit; Particularly, can adopt the mode of the mode of bitmap mapping or integer coding to indicate the change state information of a plurality of multicast control channels, wherein adopt the mode of bitmap mapping to realize that the implementation of change state information of a plurality of each self-corresponding MCCH of MBSFN of signaling indication bit indication is specific as follows described:
If co-exist in MCCH1, MCCH2, MCCH3, MCCH4, MCCH5, MCCH6, MCCH7, MCCH8 totally 8 MCCH in this residential quarter owing to existing a plurality of MBSFN zone to overlap to make in a residential quarter, and MCCH1, MCCH2, MCCH3, MCCH4, MCCH5, MCCH6, MCCH7, MCCH8 are corresponding respectively 8 different MBSFN zones, if the signaling indication bit is specially 8 bits (bits), 8 MCCH shine upon corresponding with the bit of the signaling indication bit of 8 bits mutually; If the change state information of MCCH1 changes, the signaling indication bit of 8 bits is set to 10000000 bit status, if the change state information of MCCH4 changes, the signaling indication bit of 8 bits is set to 00010000, if exist the change state information of a plurality of MCCH to change in 8 MCCH, for example: the change state information of MCCH2, MCCH5, MCCH7 changes, and the signaling indication bit is set to 01001010; Perhaps, also can adopt opposite operation, if the change state information of MCCH changes, the bit of the corresponding signaling indication bit of the change state information of MCCH is set to 0.
further, can also adopt System information block (the System Information Block of the stationary state indication MBMS in bitmap mapping, be called for short: change state information SIB) particularly, if still there is redundant state in the signaling indication bit of 8 bits, whether the SIB that the existing redundant state of this signaling indication bit is used to indicate MBMS changes, for example: because whether the signaling indication bit of 8 bits is to indicate the change state information of any one MCCH to change at 00000000 o'clock, therefore whether the SIB of 00000000 expression MBMS can be changed, particularly, the SIB that can be 00000000 expression MBMS changes, perhaps the SIB of 00000000 expression MBMS does not change.
By obtaining the change state information of MBMS, and according to the bit status that changes state information and arrange the signaling indication bit of PDCCH, UE can know that by the signaling indication bit of PDCCH change has occured the change state information of which or which MCCH, UE does not need to travel through all a plurality of MBSFN each the self-corresponding MCCH of zone in the overlapping region, has therefore reduced the complexity that UE detects.
If signaling change information is the change service reason indication information of MCCH, the bit status of signaling indication bit is set according to change service reason indication information, make UE get according to bit status the service reason that causes MCCH to change when receiving PDCCH.
The service reason such as particularly, the change service reason indication information of MCCH can start for: MBMS, MBMS stops, reshuffling; Suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, if UE gets the signaling indication bit of 3 bits in the PDCCH of form 1C type, when the change service reason indication information of MCCH changed, the change service reason indication information of the MCCH corresponding according to which or which MBSFN zone in the signaling indication bit of this 3 bit a plurality of MBSFN of indication overlapping region changed; Particularly, can adopt the mode of bitmap mapping or the mode of integer coding to realize the change service reason indication information that the signaling indication bit of 3 bits is indicated MCCH, the indicating mode of bitmap mapping is the indicating mode of bitmap mapping of the change state information of MCCH with signaling change information, does not repeat them here.
If signaling change information is the change type of service indication information of MCCH, the bit status of signaling indication bit is set according to change type of service indication information, make UE obtain according to bit status the type of service that MCCH changes when receiving PDCCH.
Particularly, the change type of service indication information of MCCH can indicate following business to change: the types of service such as the carousel business that Streaming Media, profile download, stream and document combine (Carousel business), television services; Suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, the signaling indication bit of the PDCCH of form 1C type is set according to the signaling change information of MBMS, the signaling indication bit is specially 8 bits; The mode of employing bitmap mapping or the mode of integer coding will change the type of service indication information shines upon mutually with the signaling indication bit, and further realizing indicating specifically, which or which kind of type of service causes the type of service of MCCH to change; Particularly, can set the signaling indication bit and be at 10000000 o'clock and represent that Streaming Media causes the change type of service indication information of MCCH to change, set the signaling indication bit and be at 01000000 o'clock and represent that profile download causes the change type of service indication information of MCCH to change, the bitmap mapping that changes the type of service indication information is identical with the bitmap mapping implementation of the change state information of MCCH, does not repeat them here.
The signal processing method that the embodiment of the present invention provides, the bit status of the signaling indication bit of PDCCH is set according to the signaling change information of MBMS, after receiving PDCCH, UE can know that the signaling of MBMS changes state by the signaling indication bit, make UE needn't receive one by one the signaling message of MBMS, therefore reduced the complexity that UE detects.
Fig. 3 is the schematic flow sheet of another embodiment of signal processing method of the present invention, and as shown in Figure 3, the present embodiment comprises:
If step 302 signaling change information is the change state information of the System information block of MBMS, the bit status of signaling indication bit is set according to the change state information of the System information block of MBMS, whether UE is changed according to the state that bit status obtains the System information block of MBMS when receiving PDCCH.
In above-mentioned steps 302, if signaling change information is the change state information of the SIB of MBMS, the bit status of signaling indication bit is set according to the change state information of SIB, makes UE obtain the change state of the SIB of MBMS according to bit status when receiving PDCCH.
Particularly, suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, adopt the change state information of the SIB of at least one the bit indication MBMS in the signaling indication bit, for example: the signaling indication bit that gets 1 bit in the PDCCH of form 1C type, if the signaling indication bit of 1 bit is 0 o'clock, the SIB of expression MBMS changes, and is 1 o'clock, and the SIB of expression MBMS does not change; Certainly, can be also that the signaling indication bit is 1 o'clock, the SIB of expression MBMS changes, and is 0 o'clock, and the SIB of expression MBMS does not change.
Perhaps, the signaling indication bit is 2 bits when above, and to make the signaling indication bit be all 0 or be all whether the SIB of 1 o'clock indication MBMS changes, particularly, the signaling indication bit is all that the SIB of 0 o'clock indication MBMS changes, otherwise the SIB of MBMS does not change; Perhaps the signaling indication bit is all that the SIB of 1 o'clock indication MBMS changes, otherwise the SIB of MBMS does not change.
The signal processing method that the embodiment of the present invention provides, when UE receives a plurality of MBMS, can know by the signaling indication bit in PDCCH the SIB that need to receive which or which MBMS in a plurality of MBMS, therefore only have the UE that needs reception MBMS just to receive the SIB of this MBMS, the UE that does not need to receive this MBMS does not receive the SIB of MBMS, reduce the unnecessary operation of UE, further reduced complexity and power consumption that UE carries out.
Fig. 4 is the schematic flow sheet of another embodiment of signal processing method of the present invention, and as shown in Figure 4, the present embodiment comprises the steps:
Signaling indication bit in the embodiment of the present invention is specifically as follows the individual bit of N (N is positive integer) of setting in PDCCH, and N depends on MBSFN zone number or the MCCH channel number that can support residential quarter, MBSFN place.
The signal processing method that the embodiment of the present invention provides, UE is by obtaining the signaling indication bit from PDCCH, and change information according to the signaling that the signaling indication bit gets MBMS, and change by this signaling the signaling message that information UE needn't receive MBMS one by one, therefore reduced the complexity that UE detects.
For clearer understanding technical scheme embodiment illustrated in fig. 4, have fixing number of bits take the signaling indication bit and describe as example, but fixing number of bits does not consist of the restriction to the embodiment of the present invention.In addition, the PDCCH in the embodiment of the present invention is specifically as follows the PDCCH of form 1C, is perhaps the PDCCH of form 1A; Signaling changes information can be the change information of DCI.
Particularly, the multicast control channel that changes is the multicast control channel that changes of state information and/or change multicast control channel that the service reason indication information changes and/or multicast control channel that described change type of service indication information changes for a change, all can be referred to as the change information of MCCH.
If the change information of MCCH is the change state information of MCCH, suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, UE gets the signaling indication bit of 8 bits in the PDCCH of form 1C type, due to when a plurality of MBSFN zone overlaps in same residential quarter, it is that the control information of which or which corresponding MCCH of MBSFN changes in a plurality of MBSFN that the signaling indication bit of this 8 bit can be indicated in same residential quarter; Particularly, can adopt the mode of bitmap mapping to realize the change information of the control information of signaling indication bit indication MCCH, thus UE can know that a plurality of MBSFN zone overlaps in same residential quarter by the signaling indication bit time specifically the control information of which or which MCCH change.
Thereby if in residential quarter owing to existing 8 MBSFN zones in same residential quarter, the important place district to occur, co-exist in MCCH1, MCCH2, MCCH3, MCCH4, MCCH5, MCCH6, MCCH7, MCCH8 totally 8 MCCH in this residential quarter, and MCCH1, MCCH2, MCCH3, MCCH4, MCCH5, MCCH6, MCCH7, MCCH8 are corresponding respectively 8 different MBSFN zones, if the signaling indication bit is specially 8 binary bits (bits), 8 MCCH shine upon corresponding with the bit of the signaling indication bit of 8 bits mutually; If the signaling indication bit that UE gets is 10000000 bit status, represent that the change state information of MCCH1 changes; If the signaling indication bit that UE gets is 00010000, represent that the change state information of MCCH4 changes; If the signaling indication bit that UE gets is 01001010, represent that 8 MCCH2, MCCH5, change state informations of MCCH7 in MCCH change; Perhaps, also can adopt opposite operation, if the change state information of MCCH changes, the bit of the signaling indication bit corresponding with the change state information of MCCH is set to 0.When therefore, UE can know that a plurality of MBSFN zone overlaps in same residential quarter by the signaling indication bit specifically the change state information of which or which MCCH change.
Further, if still there is redundant state in the signaling indication bit of 8 bits, whether UE can also change by the SIB that the existing redundant state of this signaling indication bit gets MBMS, particularly, if the SIB of 00000000 expression MBMS changes, be 00000000 when UE gets the signaling indication bit, represent that the SIB of MBMS changes, if not, the SIB that represents MBMS does not change; Perhaps, if the SIB of 11111111 expression MBMS changes, be 11111111 when UE gets the signaling indication bit, represent that the SIB of MBMS changes, if not, represent that the SIB of MBMS does not change.
UE is by obtaining the signaling indication bit in PDCCH, and when knowing that by the signaling indication bit a plurality of MBSFN zone occurs in same residential quarter specifically the change state information of which or which MCCH change, because UE can know that by the signaling indication bit in PDCCH the change state information of which or which MCCH changes, therefore UE does not need to travel through each self-corresponding MCCH of all MBSFN, UE also needn't receive the SIB of MBMS one by one, has therefore reduced the complexity that UE detects.
If signaling change information is the change information of the SIB of MBMS, the bit shape according to the signaling indication bit determines whether that needs receive the SIB of MBMS.
Particularly, suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, UE gets the signaling indication bit of 1 bit in the PDCCH of form 1C type, if the signaling indication bit of 1 bit is 0 o'clock, the SIB of expression MBMS changes, be 1 o'clock, the SIB of expression MBMS does not change; Certainly, the signaling indication bit also can be at 1 o'clock, and the SIB of expression MBMS changes, and is 0 o'clock, and the SIB of expression MBMS does not change; UE is by obtaining the signaling indication bit in PDCCH, and know by the signaling indication bit whether the SIB of MBMS changes, when UE receives multiple MBMS, can know by the signaling indication bit in PDCCH the SIB that whether needs to receive MBMS, therefore only have the UE that needs reception MBMS just to receive the SIB of MBMS, the UE that does not need to receive MBMS does not receive the SIB of MBMS, has reduced the unnecessary operation of UE, has further reduced complexity and power consumption that UE carries out.
Perhaps, the signaling indication bit is 2 bits when above, if the signaling indication bit that UE gets from PDCCH is all 0 or is all whether the SIB of 1 o'clock indication MBMS changes.
If signaling change information is the change service reason indication information of MCCH, UE obtains the change type of MCCH according to the change service reason indication information of control information; Particularly, the change service reason indication information of MCCH can start for: MBMS, MBMS stops, reshuffling etc.; Suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, get the signaling indication bit of 3 bits in the PDCCH of form 1C type, when the control information of MCCH changes, the change service reason indication information of the control information of which or which MCCH specifically when UE overlaps in same residential quarter according to the signaling indication bit of this 3 bit a plurality of MBSFN of indication zone; Particularly, if the mode of employing bitmap mapping realizes the signaling indication bit of 3 bits and indicates the change service reason indication information of the control information of MCCH, the indicating mode of bitmap mapping is the indicating mode of bitmap mapping of change information of the control information of MCCH with the signaling change information in embodiment illustrated in fig. 1, does not repeat them here.
If signaling change information is the type of service indication information of the control information of MCCH, the zone that obtains type of service according to the type of service indication information; Particularly, the type of service indication information of MCCH can be the carousel business that Streaming Media, profile download, stream and document combine (Carousel business), television services etc.; Suppose that PDCCH is the control channel of form 1C (format 1C) type of M-RNTI scrambling, get the signaling indication bit of 8 bits in the PDCCH of form 1C type, when a plurality of MBSFN zone overlaps in same residential quarter, due to corresponding 8 MBSFN of 8 MCCH, so UE obtains the area information of MCCH type of service according to the signaling indication bit of this 8 bit; Particularly, the mode of employing bitmap mapping realizes the change information of the SIB of signaling indication bit indication MBMS, the indicating mode of bitmap mapping is the indicating mode of bitmap mapping of the change information of MCCH with the signaling change information in embodiment illustrated in fig. 1, does not repeat them here.
