Description
Technical field
The present invention relates to wireless communication field, espespecially a kind of method and apparatus of channel multiplexing.

Existing LTE/LTE-A system carries out transmitting based on the dynamic dispatching of each subframe, and namely each subframe all can transmit different control channels.Physical Downlink Control Channel (PDCCH is defined in LTE/LTE-A, PhysicalDownlinkControlChannel) and strengthen Physical Downlink Control Channel (EPDCCH, EnhancedPhysicalDownlinkControlChannel).PDCCH and EPDCCH all can dispatch instruction physics downlink traffic channel (PDSCH, PhysicalDownlinkSharedChannel) and physical uplink Traffic Channel (PUSCH, PhysicalUplinkSharedChannel) carry out descending and transmission that is upstream data information.Fig. 1 is the schematic diagram that in existing LTE/LTE-A system descending subframe, each channel resource takies, as shown in Figure 1, PDCCH takies front several OFDMs (OFDM of full bandwidth, OrthogonalFrequencyDivisionMultiplexing) symbol, EPDCCH and PDSCH takies fractional bandwidth in frequency division multiplexing mode, i.e. part physical Resource Block (PRB, PhysicalResourceBlock) resource, in the OFDM symbol after being positioned at PDCCH.Down control channel adopts blind Detecting, and UE attempts with different polymerization grade and Candidate Set demodulation down control channel in certain search volume.Table 1 is the PDCCH search space of existing UE, table 2 is the EPDCCH search volume (situation of a distributed EPDCCHPRB set) of existing UE, as shown in Table 1 and Table 2, the Candidate Set of search volume corresponding to different polymerization grade forms, need during UE demodulation control channel to attempt each Candidate Set of demodulation until demodulation is correct, otherwise think and do not receive one's own control channel.
Table 1
Table 2
PDCCH/EPDCCH is used for bearing downlink control information (DCI, DownlinkControlInformation), and DCI comprises: uplink and downlink schedule information, and uplink power control information.Usual MTC terminal can be passed through to obtain DCI at each subframe demodulation PDCCH/EPDCCH channel, to realize the scheduling indication information of the solution mediation PUSCH to PDSCH.
A significant demand of MTC terminal is that cost is lower.One of method reduced costs at present is for reducing the reception bandwidth of MTC terminal, and such as, in LTE system, ordinary terminal still uses system bandwidth as reception bandwidth, and MTC terminal uses 1.4MHz as reception bandwidth.During MTC terminal use narrow-band reception bandwidth, the total resources that can use are very limited.When the narrow-band reception bandwidth that MTC terminal uses is less than system bandwidth, PDCCH can not work, and when using EPDCCH, in arrowband situation, control channel and Traffic Channel separate configurations PRB resource separately easily occurs the wasting of resources.Such as, EPDCCH channel adopts during distributed transmission and takies 4PRB or 6PRB, now do not have resource for PDSCH or remain little resource for PDSCH, control channel unit (ECCE, the EnhancedControlChannelElement) resource simultaneously strengthened also has residue.MTC terminal also has small data packets characteristic usually in addition; current PDSCH channel take 1PRB use lowest bit rate support 16 bits (bit); if MTC service is all packet services; suppose the order of magnitude at 10bit, so using whole PRB to transmit when channel situation is better is also waste to resource.

For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention will be further described, can not be used for limiting the scope of the invention.
The present invention proposes a kind of method of channel multiplexing, comprising: the transmission mode of data traffic channels is determined in base station, send data traffic channels according to the transmission mode determined.
Wherein, what determined transmission mode at least had in following characteristics is one or more:
In transmission mode, data traffic channels and control channel share same resource;
The control information carried in control channel in transmission mode at least comprises descending scheduling mandate or uplink scheduling authorization or up-downgoing scheduling authorization;
In transmission mode, the position candidate number of control channel is less than the first predetermined threshold value.
Wherein, UE can be arrowband MTCUE or redaction UE, and data traffic channels can be PDSCH, and control channel can be EPDCCH.
Wherein, data traffic channels and control channel are shared same resource and are comprised: data traffic channels and control channel take one or more PRB in resource jointly; Wherein, the Resource Unit that data traffic channels and control channel take is one or more ECCE.Wherein, each PRB comprises two or four ECCE.
Particularly, data traffic channels and control channel can carry out multiplexing in units of PRB, also can carry out multiplexing in units of ECCE.Such as, X PRB is a set collection, and data traffic channels and control channel take the ECCE that set concentrates jointly.Fig. 2 is the schematic diagram sharing same resource between data traffic channels and control channel.As shown in Figure 2, PDSCH and EPDCCH shares a set collection, and this set collection is 6 PRB corresponding to arrowband.EPDCCH take the 1st and 5 PRB, PDSCH take the 3rd PRB, EPDCCH and PDSCH and jointly take the 2nd, 4 and 6 PRB.
Or in one or N number of PRB, if a PRB is only for a UE, then can be used for control information transmission by an ECCE, remains three ECCE and be used for transmitting data service channel.Fig. 3 is the schematic diagram that data traffic channels or control channel take one or more ECCE in a PRB.As shown in Figure 3, EPDCCH takies ECCE, a PDSCH and takies three ECCE.
Or in one or N number of PRB, one of them PRB is used for transmitting data service channel and control channel, and remaining PRB is used for individual transmission data traffic channels or control channel.
Wherein, base station determines that the transmission mode of UE comprises: base station is with the position of the ECCE shared by predefine or fixed form determination control channel, and base station is by the position of the ECCE shared by the control information designation data Traffic Channel that carries in predefine or fixed form or control channel.
Wherein, encode separately to data traffic channels and control channel in base station, first demodulation control channel before UE reception data traffic channels, during demodulation control channel according to existing EPDCCH decode each polymerization grade (AL, AggregateLevel) of regular blind check Candidate Set corresponding to ECCE.
Wherein, after determining the position of the ECCE that data traffic channels and control channel take, the position of the ECCE shared by the control channel of each UE and data traffic channels can be mapped: a kind of is the position first mapping the control channel of a UE and the ECCE shared by data traffic channels, then maps the position of the control channel of another UE and the ECCE shared by data traffic channels by following two kinds of methods; Another kind is when base station dispatcher can dispatch all UE in a subframe, first maps the position of the ECCE shared by control channel of all UE, then maps the position of the ECCE shared by data traffic channels of all UE.
Wherein, the position of data traffic channels or the ECCE shared by control channel can be fixing, also can be unfixed.If there is ECCE fragment in resource, then ECCE fragment may be used for transmitting uplink scheduling authorization.
When the position of the ECCE shared by control channel and data traffic channels is not fixed, base station determines that the transmission mode of UE comprises: base station uses the Serial Number Range of the ECCE shared by high-level signaling notice UE control channel.The set of the position of the ECCE shared by control channel is carried in high-level signaling.
When the position of the ECCE shared by control channel is fixing, UE can carry out blind check in fixed position to control channel.
Wherein, base station determines that the transmission mode of UE comprises: base station determines that control channel takies the position of the ECCE in resource for (n-1) (N1+N2) to (n-1) (N1+N2)+N1-1, wherein, n be more than or equal to 1 positive integer, N1 is the ECCE number in every (N1+N2) individual ECCE shared by control channel, the ECCE number of N2 shared by data traffic channels.Like this, UE is when blind check control channel, and detect from the ECCE being numbered 0, single detected magnitude is N1 ECCE, and detecting step-length is (N1+N2), and detection number of times is n.
Wherein, N2 and N1 is equal or be multiple or the fixed value of N1.
When n is 1, single detected magnitude is N1 ECCE, and single detected magnitude is N1 ECCE, detects multiple or fixed value that step-length is N1.
When N2 and N1 is equal or be the multiple of N1 time, the detection step-length of UE can be N1.
Wherein, base station determines that the transmission mode of UE comprises: base station determines that the position of the ECCE that control channel takies in resource is at least the position of the ECCE of the first set correspondence, determines that position that data traffic channels takies the ECCE in resource is the position of the ECCE of the second set correspondence.Wherein, resource division is two set, and one of them is the first set, the second set another set for obtaining.
Wherein, base station determines that the transmission mode of UE comprises: base station determines that position that control channel takies the ECCE in resource is the position of the ECCE that the Candidate Set of X polymerization grade is corresponding; Wherein, X is the positive integer being less than or equal to the second predetermined threshold value.Like this, UE is when blind check control channel, detect from the ECCE being numbered 0, single detected magnitude is the ECCE number that the Candidate Set of X polymerization grade is corresponding, detects multiple or the fixed value of the ECCE number of step-length corresponding to the Candidate Set of minimum level in X polymerization grade.
The position that above-mentioned three kinds of control channels take the ECCE in resource can be combined mutually.
Wherein, in transmission mode, the position candidate number of control channel is less than the first predetermined threshold value and comprises: the polymerization grade number that in transmission mode, control channel takies is less than or equal to the second predetermined threshold value, and the Candidate Set sum corresponding to each polymerization grade is less than or equal to the first predetermined threshold value.
Wherein, the first predetermined threshold value can be 8 or 16 or 24 or 32, and the second predetermined threshold value can be 2 or 4 or 5.
Wherein, up-downgoing scheduling authorization at least comprises: downlink resource distributes (RA, ResourceAlocation) territory, up RA territory, Corticofugal Modulation of Somatosensory and coding strategy (MCS, ModulationandCodingScheme), up MCS, descending new data instruction (NDI, NewDataIndicator) one or more, in up NDI, down mixing self-retransmission request (HARQ, HybridAutomaticRepeatRequest) process.
ECCE in resource except the ECCE of each CU is for transmitting up-downgoing scheduling authorization.Such as, if subframe k comprises N
eCCE, kindividual ECCE, base station scheduler schedules m user's transmitting downlink data Traffic Channel, after m the individual ECCE of CU m (N1+N2), remaining N in subframe k
eCCE, k-m (N1+N2) individual ECCE user transmits uplink scheduling authorization, if m user just in time takes the N in subframe k
eCCE, kindividual ECCE, then do not transmit uplink scheduling authorization in subframe k.
Descending RA territory comprises: the length (quantity of ECCE and/or PRB namely taken) of ECCE and/or PRB that designation data Traffic Channel takies.
When base station determines that control channel takies the position of the ECCE in resource for (n-1) (N1+N2) to (n-1) (N1+N2)+N1-1, and n is when being more than or equal to 1 and being less than or equal to M, then in descending RA territory, the length of the ECCE that designation data Traffic Channel takies is N2.
The length range of the ECCE that data traffic channels takies can be
up RA territory or descending RA territory need at most
the length of the ECCE that bit takies with regard to energy designation data Traffic Channel.Wherein, N
eCCE, kfor the sum of the ECCE in resource.
As N2=N1, the length of the ECCE that descending RA territory designation data Traffic Channel can not be needed to take.
When N2 is the multiple of N1, the length of the ECCE that descending RA territory can adopt 1 bit designation data Traffic Channel to take is 2 times of N1 or N1, and the length of the ECCE adopting 2 Bit data Traffic Channels to take is 1 to 4 times of N1.
When a PRB is only for a UE, and have 1 ECCE in this PRB for transmitting control channel, all the other ECCE are used for transmitting data service channel; RA territory is not then needed to indicate, after UE detects control channel, then at the ECCE that the remaining ECCE of this PRB is exactly shared by data traffic channels.
As a PRB in control channel and data traffic channels shared resource, and during one or more in data traffic channels takies in resource other PRB, RA territory indicates the length of PRB position and the ECCE taken.

Wherein, UE can obtain DCI, by the bit field determination transmission mode in DCI by carrying out demodulation control channel.
Wherein, the transmission means of control channel can be centralized, also can be distributed.
When the transmission means of control channel is centralized, the transmission mode of data traffic channels is TMX, when the form of control information is DCIformatX, determines that the transmission plan of data traffic channels is send based on the single antenna port of DMRS; When the transmission means of control channel is distributed, the transmission mode of data traffic channels is TMX, when the form of control channel is DCIformatX, determines that the transmission plan of data traffic channels is send based on being used alternatingly different DMRS port between RE.
