S206, normal consistency.
The implementation process of embodiment for a better understanding of the present invention, below for the corresponding priority of different information types
And be described in detail according to the concrete mode that priority carries out information transfer.
When being embodied as, on carrier wave, the information type of transmitted information can include control information data information, this
In the case of, determine that the priority of control information is higher than the priority of data message.For example, Physical Downlink Control Channel (pdcch)
Priority be higher than not carry physical uplink shared data channel (pusch) of control information, Physical Uplink Control Channel
(pucch) priority is higher than not carry physical down shared data channel (pdsch) of control information.Correspondingly, work as transmission
During control information data information simultaneous transmission in opposite direction, for the low data message of priority, data letter can be abandoned
The transmission of breath.For the ease of description, it is respectively as a example main carrier and secondary carrier with two carrier waves as terminal scheduling for the base station, specifically
During enforcement, can be in the following ways: abandon the transmission of the data message in subframe, to ensure the correct transmission of control information.
For example, when main carrier transmits pdcch channel, during secondary carrier transmission pusch data message, abandon the transmission of pusch information；Or
When main carrier transmits pucch channel, during secondary carrier transmission pdsch data message, abandon the transmission of pdsch information；
When being embodied as, on carrier wave, the information type of transmitted information can be included on the first Downlink Control Information and first
Row control information, wherein, the first Downlink Control Information can be, but not limited to including Physical Downlink Control Channel (pdcch) or thing
Manage descending control format instruction channel (pcfich) or physical mixed autonomous retransmission (harq) designator, the first upload control letter
Up confirmation signaling (ack)/non-acknowledgement signaling (nack) that breath can be, but not limited to including terminal feedback, or terminal feedback
Uplink signal-channel quality indicates (cqi), or the detection reference signal (srs) of terminal to report.In this case, determine that first is descending
The priority of control information is higher than the priority of the first ascending control information.Correspondingly, when contrary first descending of transmission direction
When control information and the first ascending control information simultaneous transmission, for the first low ascending control information of priority, can change
Its transmission time sequence, so as to not transmit in synchronization with the first Downlink Control Information, specifically, can be divided into following three kinds of situations
Processed:
1) if the first ascending control information is up ack/nack, when transmission direction is contrary, change is up
The transmission time sequence of ack/nack, the transmission of up ack/nack is put into the sub-frame of uplink that the next one can carry ack/nack
In, still collide if the transmission of up ack/nack being put into the next one and can carrying in the sub-frame of uplink of ack/nack
When, can continue to prolong after the transmission of this up ack/nack, when being embodied as, can be by arranging the biography of up ack/nack
Prolong frequency threshold value after defeated, if prolong frequency threshold value after reaching setting, no longer transmitted the up ack/nack prolonging after this；Enter one
Step, can by the ack/nack being delayed by feedback information and terminal postpone the moment to next can transmit the ack/nack moment it
Between new ack/nack information carry out binding transmission, so, can in the case that tdd system uplink time slot is less, lifted pass
Defeated efficiency；
2) if the first ascending control information is up cqi, when transmission direction is contrary, change the biography of up cqi
Defeated sequential.Specifically, cqi can not transmitted in current collision subframe, terminal can be anti-in next cqi by current cqi information Store
On the feedback time, reported after cqi twice is carried out smoothing.
3) if the first ascending control information is srs, when transmission direction is contrary, the transmission time sequence of change srs.Its
Concrete processing mode is similar with the processing mode of cqi, repeats no more here.

Control information, wherein, the second Downlink Control Information includes descending ack/nack, and the second ascending control information includes terminal feedback
Up cqi, or the srs of terminal to report.In this case, determine that the priority of the second Downlink Control Information is up higher than second
The priority of control information.Correspondingly, when the second contrary Downlink Control Information of transmission direction and the second ascending control information are same
When transmission when, for the second low ascending control information of priority, can abandon transmit；Or coordinate the second ascending control information
Do not transmitting in the same time with the second Downlink Control Information.Specifically, when the high descending ack/nack transmission information of priority with excellent
During the low up cqi simultaneous transmission of first level, can not transmit up cqi information in collision subframe；Or coordinate descending ack/nack
With the transfer resource of up cqi feedback information, descending ack/nack and up cqi feedback information are not being passed in the same time
Defeated, for example can transmit what present sub-frame cannot transmit in the sub-frame of uplink of the main carrier after present sub-frame or secondary carrier
Cqi information, if terminal also has other up cqi information to need to transmit between described subframe and present sub-frame, can be by two
Or multiple cqi information carry out physical layer smoothing processing after transmit.
When being embodied as, on carrier wave, the information type of transmitted information can be the srs and descending cqi of terminal to report, this
In the case of kind, determine that the priority of the srs of terminal to report is higher than descending cqi.Correspondingly, when the contrary srs of transmission direction and under
During row cqi simultaneous transmission, for the low descending cqi of priority, can abandon transmitting；Or coordinate descending cqi and terminal to report
Srs do not transmitting in the same time.Specifically, when the high up srs of the priority descending cqi simultaneous transmission low with priority,
Descending cqi information can not transmitted in collision subframe；Or coordinate the transfer resource of srs and descending cqi feedback information, by srs and
Descending cqi feedback information be not transmitted in the same time.For example can be under the main carrier after present sub-frame or secondary carrier
The cqi information that in row subframe, transmission present sub-frame cannot transmit, if terminal also has other between described subframe and present sub-frame
Descending cqi information needs to transmit, and two or more cqi information can be carried out transmission after physical layer smoothing processing.
It is basic information transfer prioritization method above, further, can be according to the practical business qos of terminal
(service quality), channel conditions and actual transmissions problem etc. are optimized to base priority, for example:
1) qos according to terminal traffic requires, using more optimal information sorting mode.As terminal traffic is non-to time delay
Often sensitive, now can lift the priority of the ack/nack related to time delay；
2) according to terminal actual channel conditions, sequence is optimized, for example, it is poor that channel quality continuously in terminal,
The situation of the continuous error of data, such as when data transfer continuously malfunction number of times exceed a certain preset value when, cqi information can be lifted
Priority, contributes to resource and modulation coding mode that base station is more suitable for terminal scheduling；
3) if base station is not received by the up srs channel of terminal for a long time, uplink/downlink antenna array weight cannot accurately enter
During row, when such as base station does not receive srs number of terminal to report and exceedes a certain preset value, the priority that srs transmits can be lifted.
It is also possible to consider unified for above-mentioned factor, aggregative weighted is ranked up to service priority optimizing when being embodied as.
