Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of uplink dispatch method and device.
Background technology
When the ascending-descending subframes number was asymmetric, scheduling subframe, transmission subframe and feedback subframe can't form one-to-one relationship.For example, when the sub-frame of uplink number greater than the descending sub frame number when (comprising special time slot), the dispatch that a plurality of sub-frame of uplink are corresponding need to transmit in same descending sub frame.In this case, up indication (UL grant) need to comprise up indication (UL index) territory, is used to indicate the numbering of corresponding sub-frame of uplink.When the sub-frame of uplink number less than the descending sub frame number when (comprising special time slot), the affirmation that a plurality of descending sub frames are corresponding (ACK)/non-affirmation (NACK) information is transmitted in same sub-frame of uplink.In this case, need to comprise descending distribution indication (DAI) territory among the UL grant, be used to indicate dynamic physical downlink sharied signal channel (the Physical Downlink Shared Channel of the needs feedback in current uplink ACK/NACK feedback window, PDSCH) number and descending semi-continuous scheduling (Semi-Persistent Scheduling, SPS) whether the summation of release signaling number is used for judging in uplink ACK/NACK feedback window packet loss.
Therefore, UL index only is used for dispatching the physical uplink link sharing channel (PUSCH) of time division duplex (Time Division Duplex, TDD) uplink-downlink configuration 0, is used to indicate the numbering of corresponding sub-frame of uplink.And DAI is used to indicate the number of dynamic PDSCH of the needs feedback in the current uplink ACK/NACK feedback window and the summation of descending SPS release signaling number, whether is used for judging in uplink ACK/NACK feedback window packet loss.
In existing TDD system, UL index territory only exists when uplink-downlink configuration 0, and the DAI territory only exists when uplink-downlink configuration 1-6.Therefore, in UL grant (DCI 0 and 4) information, always only comprise one of them territory.
But the development along with technology, the particularly promotion of following three kinds of technology, the situation that the ACK/NACK information that dispatch transmits in same descending sub frame and a plurality of descending sub frame is corresponding that a plurality of sub-frame of uplink are corresponding is transmitted in same sub-frame of uplink may exist simultaneously, and current Downlink Control Information (Downlink Control Inion, DCI) design can't be supported this situation.
One, dynamic TDD.
Tdd mode as one of two large basic duplex systems under the ever-increasing background, has received increasing concern to bandwidth demand at wide-band mobile communication.Identical frequency resource is used in the uplink and downlink transmission in the TDD system, transmits uplink/downlink signals at different time slots.In common TDD system, TD SDMA access (the Time Division Synchronized Code Division Multiple Access that comprises the third generation (3G) communication system, TD-SCDMA) system and the 4th generation (4G) communication system time-division Long Term Evolution (Time Division-Long Term Evolvement, TD-LTE) system, the division of uplink and downlink time slot is static or semi-static, and common way is that basis business proportion is roughly determined unified uplink and downlink timeslot ratio and remained unchanged in network planning process.This is comparatively simple way under the background of the large covering of macrocell, and also comparatively effective.And along with technical development, the low power base station such as increasing Microcell (Pico cell), Home eNodeB (Home NodeB) are deployed be used to local little covering is provided.On the one hand, type of service (for example, data service) and macrocell (for example, speech business) difference that this class residential quarter is main, therefore, the proportioning demand difference of uplink and downlink timeslot is larger.On the other hand, the number of users of this class residential quarter is less, and the customer service changes in demand is larger, so there is situation about dynamically changing in the up-downgoing business proportion demand of residential quarter.Based on this, more dynamically configure uplink and downlink timeslot ratio and be subject to more concern and research.
Two, (inter-band) TDD in the frequency band.
In advanced person's Long Term Evolution (LTE Advanced, LTE-A) system, the peak rate of system has huge raising than LTE, requires to reach descending 1Gbps, up 500Mbps.If only using a maximum bandwidth can't reach peak rate as the carrier wave of 20MHz requires.Therefore, the LTE-A system needs the operable bandwidth of terminal extension, introduced thus carrier aggregation (Carrier Aggregation, CA) technology, be about under the same eNB (base station) a plurality of continuous or discrete carrier aggregation together, simultaneously for the UE service, so that required speed to be provided.These carrier waves that condense together are called again member carrier (component carrier is called for short CC).Each residential quarter can be a member carrier, and the residential quarter under the different e NB (member carrier) can not polymerization.For the UE that guarantees LTE can work under the carrier wave of each polymerization, each carrier wave maximum is no more than 20MHz.The CA technology of LTE-A as shown in Figure 1, have under the base station of LTE-A 4 can polymerization carrier wave, the base station can be simultaneously on 4 carrier waves and UE carry out transfer of data, to improve throughput of system.
In the system of LTE version 11 (Rel-11) or later version, for fear of the interference to other TDD systems, different TDD up/down row sub-frame configuration may be used in the LTE residential quarter that is positioned at different frequency bands (Band), as shown in Figure 2, wherein carrier wave 1 and carrier wave 2 are positioned at Band A, carrier wave 3 is positioned at Band B, and residential quarter 1, residential quarter 2 and residential quarter 3 are respectively the residential quarters on carrier wave 1, carrier wave 2 and the carrier wave 3.The TDD uplink-downlink configuration of residential quarter 1 and residential quarter 2 is identical, is configuration 1, and the TDD up/down row sub-frame configuration of residential quarter 3 is different with residential quarter 2 from residential quarter 1, for configuring 2.If terminal wishes to utilize these three residential quarters to carry out carrier aggregation, the different situation of TDD uplink-downlink configuration of all aggregation cell of terminal will appear so.
Three, Frequency Division Duplexing (FDD) (FDD) and TDD polymerization.
In the follow-up evolution system of LTE, may support TDD carrier wave and FDD descending (DL) carrier aggregation.
In sum, DCI of the prior art can't support the situation that dispatch corresponding to a plurality of sub-frame of uplink transmits and a plurality of descending sub frame is corresponding ACK/NACK information is transmitted simultaneously in same sub-frame of uplink in same descending sub frame.
