Background technology

At LTE (LongTermEvolution, Long Term Evolution) in system, up-downgoing resource scheduling information (such as: the information such as resource allocation result, code modulation mode) is all carried by PDCCH (PhysicalDownlinkControlChannel, Physical Downlink Control Channel).And the DCI (DownlinkControlInformation, Downlink Control Information) in PDCCH contains Resourse Distribute on one or more UE and other control informations.Each UE is after getting PDCCH, by DCI in demodulation PDCCH, determine the PDSCH (PhysicalDownlinkSharedChannel of transmitting downlink data, Physical Downlink Shared Channel) corresponding resource location, and the resource location that the PUSCH (PhysicalUplinkSharedChannel, Physical Uplink Shared Channel) determining transmit ascending data is corresponding.

That is, transmitting uplink data and downlink data transmission all to need PDCCH to carry schedule information, but due to PDCCH resource limited, caused the problem how for transmitting uplink data link and downlink data transmission link assignment PDCCH resource.The mode addressed this problem at present has two kinds: a kind of mode is the PDCCH resource determining transmitting up-downgoing data according to up-downgoing service resources demand; Another kind of mode is the maximum CCE (ControlChannelElement that can be assigned with according to up-downgoing channel quality determination up-downgoing data transmission link, control channel unit) number of resources, ensure that the CCE resource of PDCCH channel is used by up-downgoing data transmission link equity dispatching.

Along with data service in a mobile network universal, the up-downgoing of usual data service is asymmetrical, and that is uplink service and downlink business demand are different.Such as: downloading service, require higher to the QoS (QualityofService, quality of service) of downlink data transmission link; Send out mail service, require lower to the QoS (QualityofService, quality of service) of transmitting uplink data link.

But adopt existing two kinds of modes, the single PDCCH resource determining transmission up-downgoing data according to up-downgoing service resources demand or up-downgoing channel quality, there is priority allocation PDCCH resource and send out mail service for performing, downloading service is made to be in wait state, lagging distribution PDCCH resource is for performing downloading service, that is, priority allocation PDCCH resource performs sends out mail service, the downloading service higher to downlink data transmission link requirement is made to delay to perform like this, easily make to occur network congestion in communication system, also just make the utilization rate of PDCCH resource lower.

Below in conjunction with Figure of description, each embodiment of the present invention is described in detail.

Embodiment one:

As shown in Figure 1, be the schematic flow sheet of the dispatching method of a kind of physical downlink control channel resource of the embodiment of the present invention one, described method comprises:

Step 101: before each transmission time interval TTI distributes Physical Downlink Control Channel PDCCH resource, obtains the Physical Uplink Shared Channel PUSCH time domain dispatching priority of each uplink user and the Physical Downlink Shared Channel PDSCH time domain dispatching priority of each downlink user.

In a step 101, first, before each transmission time interval TTI distributes Physical Downlink Control Channel PDCCH resource, from up time domain scheduler and descending time domain scheduler, read all uplink user PUSCH time domain scheduling priority information and all downlink user PDSCH time domain scheduling priority information respectively.

Such as: uplink user i is at the PUSCH time domain dispatching priority p of t _{pUSCH_i}(t), i=1,2 ..., K _uL, K _uLfor the number of all uplink user, downlink user j is at the PDSCH time domain dispatching priority p of t _{pDSCH_j}(t), j=1,2 ..., K _dL, K _dLfor the number of all downlink users.

It should be noted that, each transmission time interval TTI is generally 1ms.

Secondly, the PUSCH time domain dispatching priority of each uplink user read is normalized, obtains the PUSCH time domain dispatching priority of the uplink user after normalization.

Particularly, in the following manner the PUSCH time domain dispatching priority of each uplink user is normalized, obtains the PUSCH time domain dispatching priority of the uplink user after normalization:

$p_{PUSCH\_i}=\frac{p_{PUSCH\_i}\left(t\right)}{P_{\max \_i}\left(t\right)},i=1,2,...,K_{UL};$

Wherein, p _{pUSCH_i}t PUSCH time domain dispatching priority that () is t uplink user i, P _{max_i}the maximum of t PUSCH time domain dispatching priority that () is all uplink user, p _{pUSCH_i}for obtaining the PUSCH time domain dispatching priority of the uplink user i after normalization, K _uLfor the number of uplink user;

The PDSCH time domain dispatching priority of each downlink user read is normalized, obtains the PDSCH time domain dispatching priority of the downlink user after normalization.

Particularly, in the following manner the PDSCH time domain dispatching priority of each downlink user is normalized, obtains the PDSCH time domain dispatching priority of the downlink user after normalization:

$p_{PDSCH\_j}=\frac{p_{PDSCH\_j}\left(t\right)}{P_{\max \_j}\left(t\right)},j=1,2,...,K_{DL};$

Wherein, p _{pDSCH_j}t PDSCH time domain dispatching priority that () is t downlink user j, P _{max_j}the maximum of t PDSCH time domain dispatching priority that () is all downlink users, p _{pDSCH_j}for obtaining the PDSCH time domain dispatching priority of the downlink user j after normalization, K _dLfor the number of downlink user.

Step 102: according to channel quality value and the up-downgoing business datum amount of upstream and downstream user, determines that each uplink user distributes the weighted value of PDCCH and the weighted value of each downlink user distribution PDCCH.

In a step 102, first, judge whether the update cycle that PDCCH assigns weight reaches.

The update cycle assigned weight due to PDCCH is longer than transmission time interval, when determining the assigning weight of PDCCH, need to judge whether the update cycle that PDCCH assigns weight reaches, that is, when the update cycle that PDCCH assigns weight does not reach, PDCCH is kept to assign weight constant.

Such as: the update cycle that PDCCH assigns weight is 10ms, the update time that last PDCCH assigns weight is T0, this moment obtaining all uplink user PUSCH time domain scheduling priority information and all downlink user PDSCH time domain scheduling priority information is T3, as T3-T0=10, determine that the update cycle that PDCCH assigns weight arrives; When T3-T0 is less than 10, determine that the update cycle that PDCCH assigns weight does not arrive, the weighted value of the distribution PDCCH determined according to the T0 moment performs subsequent operation.

Secondly, when the update cycle that PDCCH assigns weight reaches, according to channel quality value and the up-downgoing business datum amount of upstream and downstream user, each uplink user calculated in the current update cycle distributes the weighted value of PDCCH and the weighted value of each downlink user distribution PDCCH.

Particularly, the first step, determines up average channel quality value according to the channel measured value of uplink user, and according to the buffer status report of reporting of user, calculates the average traffic quantitative value of uplink user.

Namely obtain the channel measured value of T3 moment uplink user, calculate up average channel quality value.

Such as: wherein, CQI _it channel measured value that () reports for T3 moment uplink user i, K _uLfor the number of uplink user.

Obtain again the buffer status report (i.e. uplink service quantity information) that T3 moment uplink user reports, calculate the average traffic quantitative value of uplink user.

Such as: wherein, BUF _it () is the uplink service quantitative value of T3 moment uplink user i, K _uLfor the number of uplink user.

Same mode, the channel feedback value according to downlink user determines descending average channel quality value, and according to the queue of base station down data buffer storage, calculates the average traffic quantitative value of downlink user.

Particularly, namely obtain the channel feedback value of T3 moment downlink user, calculate descending average channel quality value.

Such as: wherein, CQI _jt channel quality value that () feeds back for T3 moment downlink user j, K _dLfor the number of downlink user.

Obtain downlink data buffer queue (i.e. downlink business quantity information) in T3 moment base station again, calculate the average traffic quantitative value of downlink user.

Such as: wherein, BUF _jt () is the downlink business quantitative value of T3 moment downlink user j, K _dLfor the number of downlink user.

Second step, utilize the described up average channel quality value determined, described descending average channel quality value, the average traffic quantitative value of described uplink user of calculating and the average traffic quantitative value of described downlink user, calculate the weight controlling elements of PDCCH and the average weight controlling elements of PDCCH.

Particularly, utilize the described up average channel quality value determined, described descending average channel quality value, the average traffic quantitative value of described uplink user of calculating and the average traffic quantitative value of described downlink user, calculate the weight controlling elements of PDCCH in the following manner:

$p\left(t\right)=\frac{{\mathrm{BUF}}_{UL}\left(t\right)}{{\mathrm{BUF}}_{DL}\left(t\right)}*\frac{{\mathrm{CQI}}_{UL}\left(t\right)}{{\mathrm{CQI}}_{DL}\left(t\right)};$

Wherein, BUF _uLt average traffic quantitative value that () is t uplink user, BUF _dLt average traffic quantitative value that () is t downlink user, CQI _uLt () is the up average channel quality value of t, CQI _dLt () is the descending average channel quality value of t.

And calculate the average weight controlling elements of PDCCH in the following manner:

$\stackrel{\‾}{p}\left(t\right)=(1-\frac{1}{t_c})\stackrel{\‾}{p}(t-k)+\frac{1}{t_c}p\left(t\right);$

Wherein, for the average weight controlling elements of t PDCCH, the weight controlling elements that p (t) is t PDCCH, t _cfor window update time, k is the update cycle value that PDCCH assigns weight, and t-k is the moment doing sth. in advance k duration than t.

It should be noted that, for the average weight controlling elements of t PDCCH, so for the average weight controlling elements of (t-k) moment PDCCH.Such as: suppose that t is be worth 8:00, the k update cycle for 10s, then the t-k moment refers to that 8:00 pushes away forward 10s, i.e. 7:59:50, so for the average weight controlling elements of 8:00 moment PDCCH, for the average weight controlling elements of 7:59:50 moment PDCCH.

3rd step, the weight controlling elements of described PDCCH relatively calculated and the average weight controlling elements of described PDCCH, and according to comparative result, determine that each uplink user in current period distributes the weighted value of PDCCH and the weighted value of each downlink user distribution PDCCH.

Particularly, when the weight controlling elements of described PDCCH are less than the average weight controlling elements of described PDCCH, the weighted value that each uplink user distributes PDCCH reduces the weight step-length set, and each downlink user distributes the weight step-length of the weighted value increase setting of PDCCH.

Such as: $\left\{\begin{array}{c}{w}_{UL}\left(t\right)=w_{UL}(t-k)-\mathrm{\Δ}w\\ w_{DL}\left(t\right)=w_{DL}(t-k)+\mathrm{\Δ}w\end{array}\right.,\stackrel{\‾}{p}(t-k)>p\left(t\right).$

It should be noted that, Δ w is the weight step-length of setting, w _uL(t-k) for uplink user in the adjacent upper update cycle distributes the weighted value of PDCCH; w _dL(t-k) for downlink user in the adjacent upper update cycle distributes the weighted value of PDCCH, when the update cycle is 1, initial w _uLand w _dLequal 1, also can determine according to actual needs, not limit here.

When the weight controlling elements of described PDCCH are greater than the average weight controlling elements of described PDCCH, the weighted value that each uplink user distributes PDCCH increases the weight step-length set, and each downlink user distributes the weight step-length of the weighted value minimizing setting of PDCCH.

Such as: $\left\{\begin{array}{c}{w}_{UL}\left(t\right)=w_{UL}(t-k)+\mathrm{\&Delta;}w\\ w_{DL}\left(t\right)=w_{DL}(t-k)-\mathrm{\&Delta;}w\end{array}\right.,\stackrel{\&OverBar;}{p}(t-k)<p\left(t\right).$

When the weight controlling elements of described PDCCH equal the average weight controlling elements of described PDCCH, the weighted value that each uplink user distributes PDCCH remains unchanged, and the weighted value that each downlink user distributes PDCCH remains unchanged.

Such as: $\left\{\begin{array}{c}{w}_{UL}\left(t\right)=w_{UL}(t-k)\\ w_{DL}\left(t\right)=w_{DL}(t-k)\end{array}\right.,\stackrel{\&OverBar;}{p}(t-k)=p\left(t\right).$

As can be seen here, up average channel quality is larger, and the user that PUSCH can carry is more, therefore increases up PDCCH and assigns weight, and improves the up number of users be scheduled; Up average traffic data volume is larger, and illustrate that the data to be sent such as uplink user buffer queue are more, wait for that time delay is longer, user more needs preferentially to be scheduled, and therefore increases up PDCCH to assign weight, and improves the up number of users be scheduled.

Or descending average channel quality is larger, the user that PDSCH can carry is more, therefore increases descending PDCCH and assigns weight, and improves the descending number of users be scheduled; Descending average traffic data volume is larger, and illustrate that the data to be sent such as downlink user buffer queue are more, wait for that time delay is longer, user more needs first to be scheduled, and therefore increases descending PDCCH to assign weight, and improves the descending number of users be scheduled.

Step 103: the weighted value distributing PDCCH according to PUSCH time domain dispatching priority and this uplink user determined of each uplink user obtained, obtain the priority value of the distribution PDCCH resource of each uplink user, and the weighted value of PDCCH is distributed according to the PDSCH time domain dispatching priority of each downlink user obtained and this downlink user of determining, obtain the priority value of the distribution PDCCH resource of each downlink user.

In step 103, carried out doing long-pending computing by the weighted value that the PUSCH time domain dispatching priority of each uplink user obtained and this uplink user determined distribute PDCCH, the product value obtained is the priority value of the distribution PDCCH resource of this uplink user.

Such as: p _{uL_i}(t)=p _{pUSCH_i}(t) × w _uL(t) i=1,2 ..., K _uL, wherein, p _{pUSCH_i}t PUSCH time domain dispatching priority that () is uplink user i, w _uLt () is the weighted value of uplink user i distribution PDCCH.

P _{dL_j}(t)=p _{pDSCH_j}(t) × w _dL(t) j=1,2 ..., K _dL, wherein, p _{pDSCH_j}t PDSCH time domain dispatching priority that () is downlink user j, w _dLt () is the weighted value of downlink user j distribution PDCCH.

As can be seen here, as uplink signal-channel quality CQI _uLduring increase, PUSCH can carry more uplink user, at this moment the PDCCH weight factor w of uplink assignment _uLincrease, simultaneously descending distribution PDCCH weight factor w _dLreduce, improve the PDCCH priority of uplink user, make more uplink user obtain PDCCH channel resource.As the average traffic data volume BUF of uplink user _uLduring reduction, simultaneously because the PDCCH blocking rate increase of downlink user makes the resource utilization of PDSCH reduce, the average traffic data volume BUF of downlink user _dLcan increase, therefore descending distribution PDCCH weight factor w _dLincrease, simultaneously uplink assignment PDCCH weight factor w _uLreduce, improve the PDCCH priority of downlink user, make more downlink user obtain PDCCH channel resource.

As down channel quality CQI _dLduring increase, PDSCH can carry more downlink user, at this moment descending distribution PDCCH weight factor w _dLincrease, simultaneously uplink assignment PDCCH weight w _uLreduce, improve the PDCCH priority of downlink user, make more downlink user obtain PDCCH channel resource.In order to improve the resource utilization of PDSCH, as the average traffic data volume BUF of downlink user _dLduring reduction, the PDCCH blocking rate due to uplink user increases makes the resource utilization of PUSCH reduce, along with the average traffic data volume BUF of uplink user _uLincrease, therefore uplink assignment PDCCH weight factor w _uLincrease, descending distribution PDCCH weight factor w _dLreduce, improve the PDCCH priority of uplink user, make more uplink user obtain PDCCH channel resource.

In sum, according to the change of up-downgoing channel quality and up-downgoing business datum amount, self-adaptative adjustment PDCCH assigns weight, and makes the user that channel quality is poor, resource requirement is little obtain less PDCCH resource, avoids the waste of PDCCH resource.

Step 104: according to the ordering rule of setting, the priority value of the priority value of the distribution PDCCH resource of each uplink user obtained and the distribution PDCCH resource of each downlink user is carried out associating sequence, and according to ranking results, be followed successively by upstream and downstream user and distribute PDCCH resource.

At step 104, the priority value p of multiple distribution PDCCH resource will obtained _{uE_m}(t) (wherein, m=1,2 ..., K _uL+ K _dL) carry out associating sequence according to the sequence of setting.

The ordering rule of usual setting arranges according to order from high to low.

Like this priority of the priority of uplink user and downlink user is integrated and sort, the user priority that priority is relatively high obtains PDCCH resource, again remaining PDCCH resource is distributed to the low user of priority, avoid occurring first distributing PDCCH resource to the user that QoS is lower and situation that the user PDCCH that causes QoS higher blocks, better ensure the qos requirement of user.

By the scheme of the embodiment of the present invention one, according to the change of up-downgoing channel quality and up-downgoing business datum amount, self-adaptative adjustment PDCCH assigns weight, the user that channel quality is poor, resource requirement is little is made to obtain less PDCCH resource, avoid the waste of PDCCH resource, improve the utilance of PDCCH resource.
