In declarative procedure below, first from the cooperation of network side and user equipment side, implement to describe, finally from the enforcement of network side and user equipment side, describe respectively, but this does not also mean that the two must coordinate enforcement, in fact, when network side and user equipment side, separate while implementing, also solved respectively in network side, the existing problem of user equipment side, when just the two is combined with, can obtain better technique effect.
As shown in Figure 1, embodiment of the present invention descending scheduling system comprises: network equipment 10 and subscriber equipment 20.
Network equipment 10, for determining each many subframes set, wherein each many subframes set comprises at least one descending sub frame; From all many subframes set, select part or all of many subframes set, and send for dispatching the down dispatch information of at least one descending sub frame to subscriber equipment by a descending sub frame in many subframes set of each selection;
Subscriber equipment 20, for determining each many subframes set, wherein each many subframes set comprises at least one descending sub frame; By a descending sub frame in each many subframes set, detect for dispatching the down dispatch information of at least one descending sub frame.
In force, network equipment and subscriber equipment can, according to She Ge in advance or the mode such as negotiations mutually, be determined from many subframes set of selection and select descending sub frame.
Wherein, it is a variety of that the embodiment of the present invention determines that the mode of each many subframes set has, and enumerates several below.
Mode one, the set of many subframes are relevant to up-downgoing Pei Ge.
Wherein, network equipment and subscriber equipment, according to current up-downgoing Pei Ge, are determined each many subframes set.
In this mode, the set of many subframes is relevant to up-downgoing Pei Ge, i.e. many subframes set She Ge is corresponding one by one with up-downgoing Pei Ge.
Concrete, network equipment and subscriber equipment, according to current up-downgoing Pei Ge, are determined the sub-frame of uplink that each descending sub frame is corresponding, wherein the sub-frame of uplink of the feedback information of bearing downlink subframe is the sub-frame of uplink that this descending sub frame is corresponding; Using the descending sub frame of the same sub-frame of uplink of correspondence as subframe collection more than.
In force, the set of many subframes corresponding with feedback window (feedback window be one can bearing downlink subframe the sub-frame of uplink of feedback information).A descending sub frame corresponding to feedback window is as subframe set more than.The corresponding RTT that can avoid increases with feedback window, because the descending sub frame in feedback window all feeds back in same sub-frame of uplink, can from 1, not be increased to because of the descending sub frame number of scheduling manyly, and extends feedback delay, then affects rescheduling of corresponding process.On the contrary, if the descending sub frame in the set of many subframes is distributed in different feedback windows, the new data transmission of the corresponding processes of these subframes or retransmit and all will feed back the feedback subframe that window is corresponding with last and be as the criterion, and at least 4 subframes after this feedback subframe could be initiated to dispatch.Like this, for the descending sub frame feeding back above in window, the time delay of its reschedule can increase to some extent.
Preferably, many subframe schedulings DL grant signaling Jin Pei Ge is in first descending sub frame corresponding to feedback window.That is, subscriber equipment only detects at first descending sub frame corresponding to feedback window.
The set of many subframes can be set as required with the corresponding relation of feedback window.The table 1 of take below describes as example.It should be noted that, the corresponding relation of the set of many subframes of the embodiment of the present invention and feedback window is not limited to the mode of table 1, and the set of many subframes is suitable for the embodiment of the present invention too with other corresponding relations of feedback window.
As shown in table 1, a descending sub frame corresponding to feedback window is as subframe set more than.In many subframe schedulings system of up-downgoing Pei Ge Wei Pei Ge 2, have subframe set more than two, { subframe 4, subframe 5, subframe 6, subframe 8} is subframe set more than, { the subframe 9 of radio frames n, the subframe 0 of radio frames n+1, subframe 1 and subframe 3} are the set of many subframes of another one.In this system, adopt the subscriber equipment of many subframe schedulings, can only be scheduled according to combinations thereof, and subscriber equipment only detects schedule information in the subframe 4 of radio frames n and the subframe of radio frames n 9.In many subframe schedulings system of up-downgoing Pei Ge Wei Pei Ge 1, have subframe set more than four: { subframe 0, subframe 1}, subframe 4, { subframe 5, subframe 6}, subframe 9.The subscriber equipment that adopts many subframe schedulings in this system, is scheduled according to combinations thereof, and subscriber equipment is only in the subframe 0 of radio frames n, subframe 4, and subframe 5, detects schedule information in subframe 9.By that analogy, can obtain many subframe scheduling methods of other up-downgoings Pei Ge.Because the feedback of all descending sub frames in the set of many subframes and the feedback correspondence of first descending sub frame in the set of many subframes are at same sub-frame of uplink, therefore, avoid the overall feedback causing because of a plurality of subframes of scheduling to delay, and then avoided the delay retransmitting.
The quantity of the subframe comprising in many subframes set of mode two, the set of many subframes to Pei Ge is relevant.
Network equipment, according to the quantity of the subframe comprising in many subframes set of Pei Ge, is determined each many subframes set.
Subscriber equipment, according to the quantity of the subframe comprising in many subframes set of network side Pei Ge, is determined each many subframes set.
The quantity of the subframe comprising in many subframes set of ， Pei Ge in force can preset; Also can be by high-rise Pei Ge to network equipment; Also can be by the Hang Pei Ge of network equipment self Jin; Can also be by the Hang Pei Ge of artificial Jin.Wherein, the quantity of the subframe that network equipment comprises in can many subframes set of notifying user equipment Pei Ge, such as notifying by high-level signaling.
Preferably, can be from { selecting in 2,4}, or from { selecting in 2,3,4}, or from { selecting in 2,4,8}.Because many subframes set sizes can Ling Huo Pei Ge, compared with Gu, Ding Pei Ge and can adapt to business demand, also can reduce signaling consumption.For example, when many subframes set sizes, joining Ge is 2, and PDCCH design only needs to consider the situation of 2 subframe schedulings, and when many subframes set sizes, joining Ge is 4, and the situation of 4 subframe schedulings is considered in PDCCH design.So just need to not be as the criterion and design PDCCH signaling with the most most subframe set.
In force, the descending sub frame that each many subframes set that network equipment and subscriber equipment are determined according to the quantity of the subframe comprising in many subframes set of Pei Ge comprises is continuous descending sub frame.Such as, many subframes set can by arbitrarily M continuously descending sub frame form; Also can be formed by the M a determining descending sub frame.M is the number of descending sub frame in many subframes set of high-level signaling Pei Ge.
If formed by the M a determining descending sub frame, can preset the corresponding relation of M and the set of many subframes, set up in advance the corresponding relation of the descending sub frame comprising in each many subframes set of M value and correspondence.
For mode two, if the set of many subframes by M arbitrarily continuously descending sub frame form, can, according to different M values, stipulate which subframe is subframe set more than, such as M is at 4 o'clock, can stipulate subframe 0, subframe 1, subframe 4 and subframe 5 are subframe set more than, subframe 6, subframe 7, subframe 8 and subframe 9 are subframe set more than.Preferably can arrange to select which or which descending sub frame in the set of many subframes as the descending sub frame of scheduling.Such as can only selecting first descending sub frame, network equipment only sends schedule information in subframe 0 and subframe 6 like this, and subscriber equipment also only detects in subframe 0 and subframe 6.
For mode two, if the set of many subframes is comprised of the M determining a continuous descending sub frame, and do not stipulate which subframe is subframe set more than, subscriber equipment need to detect on all descending sub frames in the set of many subframes.
For mode two, enumerate two examples.
Example 1: in many subframe schedulings system of up-downgoing Pei Ge Wei Pei Ge 1, when subscriber equipment receives that high-level signaling indicates many subframes set sizes to be 2, two the adjacent descending sub frames of can take are arbitrarily scheduled as subframe set more than.For example, subframe 0 and subframe 1, subframe 1 and subframe 4, subframe 4 and subframe 5, subframe 5 and subframe 6, subframe 6 and subframe 9, the subframe 9 of radio frames n and the subframe 0 of radio frames n+1 can be respectively as subframe set more than.Subscriber equipment all carries out down dispatch information detection to all descending sub frames in all many subframes set.
Example 2: in many subframe schedulings system of up-downgoing Pei Ge Wei Pei Ge 2, when subscriber equipment receives that high-level signaling indicates many subframes set sizes to be 4, subframe 0, subframe 1, subframe 4 and subframe 5 are subframe set more than, subframe 6, subframe 7, subframe 8 and subframe 9 are the set of many subframes of another one.Subscriber equipment only detects schedule information in subframe 0 and subframe 6.Or 4 descending sub frames of arbitrary continuation are subframe set more than, subscriber equipment all detects schedule information at all descending sub frames.When subscriber equipment receives that high-level signaling indicates many subframes set sizes to be 2, this system comprises subframe set more than 4: subframe 0 and subframe 1, subframe 4 and subframe 5, subframe 6 and subframe 7, subframe 8 and subframe 9.Subscriber equipment is only in subframe 0, and subframe 4, detects schedule information in subframe 6 and subframe 8.Or 2 descending sub frames of arbitrary continuation are subframe set more than, subscriber equipment all detects schedule information at all descending sub frames.
Particular user equipment is to select which descending sub frame in the set of many subframes to detect can to preset or network side is notified or agreement setting etc.No matter adopt which kind of mode, as long as guarantee subscriber equipment and network equipment for the descending sub frame understanding in the subframe set detecting always.
In the descending sub frame that network equipment can detect at subscriber equipment, send down dispatch information.
Due to the understanding of the descending sub frame in the corresponding many subframes set of network equipment and subscriber equipment always, and network equipment knows that the descending sub frame of subscriber equipment in which many subframes set detects, and receives schedule information so can realize subscriber equipment.
Normally, when system is the set of many subframes of subscriber equipment Pei Ge, need to consider the needed number of sub frames of user device transmissions data, avoid many subframes set of Pei Ge to be greater than the number of sub frames that subscriber equipment needs, cause waste.For example, when subscriber equipment only has small data transmission, it is 2 that system Ke be take the quantity of the descending sub frame in the set of many subframes of Pei Ge, and when user is transmitted large data, the quantity of the descending sub frame in the set of many subframes of Xi Tong Pei Ge is 4.
Mode three, the set of many subframes are relevant with the quantity of the subframe comprising in many subframes set of Pei Ge to up-downgoing Pei Ge.
This mode is that mode one and mode two are combined, and according to the condition of setting, selects to adopt which kind of mode.
Concrete condition can be set as required, take below and describes as condition is chosen as example according to the quantity of the descending sub frame comprising in the set of many subframes.
In force, can select according to following manner:
Quantity=min{ mode one of the descending sub frame comprising in the set of many subframes, mode two } or max{ mode one, mode two }.
Concrete, network equipment is determined each many subframes set according to current up-downgoing Pei Ge, determine the quantity of many subframes set at the descending sub frame place need to carry out descending scheduling, and by the quantity of many subframes set at the descending sub frame place that need to carry out descending scheduling of determining Yu the quantity of the subframe comprising in many subframes set of Pei Ge compare;
Network equipment is according to comparative result, from determining the mode of each many subframes set according to current up-downgoing Pei Ge and determining according to the quantity of the subframe comprising many subframes set of Pei Ge in the mode of each many subframes set and select a kind of mode, and determine each many subframes set according to the mode of selecting.
Accordingly, subscriber equipment is determined each many subframes set according to current up-downgoing Pei Ge, determine the quantity receive the descending sub frame of descending control signaling or many subframes set at the descending sub frame place that descending control signaling need to be dispatched, and the quantity of the subframe comprising in the quantity of many subframes set at the descending sub frame place that the descending sub frame of receiving descending control signaling of determining or descending control signaling need to be dispatched and many subframes set of network side Pei Ge compares;
Subscriber equipment is according to comparative result, from determining the mode of each many subframes set according to current up-downgoing Pei Ge and determining according to the quantity of the subframe comprising many subframes set of network side Pei Ge in the mode of each many subframes set and select a kind of mode, and determine each many subframes set according to the mode of selecting.
The quantity of the mode of selecting in two quantity that wherein, compare is greater than or less than the quantity of another kind of mode.
Such as setting quantity=min{ mode one of the descending sub frame comprising in the set of many subframes, mode two }, by definite quantity Yu the quantity of the subframe comprising in many subframes set of Pei Ge compare, if definite quantity is less than the quantity of the subframe comprising in many subframes set of Pei Ge, selection mode one; Otherwise selection mode two; If two quantity are identical, select one or select one according to setting means at random from two modes, such as setting two identical selection modes one of quantity, selection mode one when two quantity are identical.
