It is discussed further below from the process that trunking 121 is terminal device allocation of downlink transfer resource.In order to describe
It is convenient, the number for the terminal device for being connected to trunking 121 is set as n, n is positive integer.N terminal device include
Terminal device 122 and 123.First, by the path loss of the determination trunking 121 of trunking 121 to multiple terminal devices.In
The path loss of terminal device can be measured after equipment 121 by finding signaling channel PSDCH or data channel PSSCH.
Then trunking 121 determines the required received signal power of multiple terminal devices.Then, trunking 121 is based on institute really

Above-mentioned selection course is repeated to select a terminal every time in remaining terminal and meet above-mentioned two condition i.e.
The product of maximum required resource block power and the number of the resource block of the allocated resource in selected terminal device
No more than can be used for the Upper Bound Power of a logic subframe, and being put into the summation of the resource block of a logic subframe cannot
More than the total number of resource block possessed by the logic subframe.
Above-mentioned selection course is repeated, the terminal until not meeting above-mentioned two condition can be selected
Remaining terminal device number is m, and m is positive integer.Similarly, by trunking 121 then to this m terminal
The required resource block transimission power of equipment is compared, and obtains P1"≥P2”≥...≥Pm".Continue to judge using above-mentioned condition
Method, the resource block for the terminal device for meeting above-mentioned two condition is assigned to the second logic subframe.Repeat distribution above
Mode, until the resource block of all terminal devices is all assigned in some logic subframe.
In certain embodiments, logic subframe is mapped to physical sub-frame by trunking 121.The mode of mapping can be with
Machine maps or fixed mapping.
By method 200, downlink traffic can be grouped into the subframe of lesser number by trunking 121, and can
To reduce total power consumption.Moreover, less downlink subframe means that can retain more subframes sets for terminal
Standby uplink transmission, to improve system performance.
Fig. 3 shows the method 300 of the resource allocation for trunking traffic of another embodiment according to present disclosure
Flow chart.Method 300, which corresponds between the network equipment 110 does not use relaying cluster, interferes the situation of control.Method 300 for example may be used
To be executed by trunking 121.
302, at trunking 121,110 not enabled of network equipment relaying associated with trunking 121 is determined
Anti-interference function between device cluster.In certain embodiments, the mode for the anti-interference function that the network equipment 110 may be used is
Orthogonal resource pool is distributed to neighbouring relaying cluster 120 and 130, to inhibit interfering with each other between relaying cluster 120 and 130.
In one embodiment, the anti-interference function of the network equipment 110 can be preconfigured.In another embodiment, net
The anti-interference function of network equipment 110 is in response to open in the request of trunking 121.
304, at trunking 121, the network equipment is directed in multiple terminal devices associated with trunking 121
Unscheduled terminal device, determine the required transimission power of resource block and number for carrying out downlink transmission.
At 306, at trunking 121, the sequential scheduling according to the number of the resource block of multiple terminal devices is multiple
Distribution of the resource block of terminal device to logic subframe.The execution acted above can be that iteration carries out, i.e., step 304 and
306 need at least to execute once.Hereinafter the process of iteration will be described in more detail.
In certain embodiments, in order to reduce signaling overheads, the resource of terminal device 122 and the transmission of 123 pairs of uplinks
Independently selected.In the case of anti-interference function between the network equipment 110 does not take adjacent relay cluster, such as network is set
Standby 110 are assigned with the same asset pond with Q subframe to relaying cluster 120 and 130, then relaying can occur between cluster 120 and 130
Interference.At this moment trunking 121 needs to consider in cluster 120 for the distribution of the efficient resource of uplink and downlink traffic
Problem.Trunking 121 mitigates the interference between relaying cluster dependent on randomization.In order to reach the mesh for reducing and being interfered between cluster
, the downlink resource blocks of multiple terminal devices are assigned to downlink subframe as homogeneously as possible in the scheme of the application
In.
The process that trunking 121 is terminal device allocation of downlink transfer resource is discussed further below.For the side of narration
Just, the number for the terminal device for being connected to trunking 121 is set as n, n is positive integer.
First, the amount of the flow based on downlink and uplink is determined by trunking 121 for downlink
The number W of logic subframe.Then (Q-W) a logic subframe is used for uplink transmission.Due to uplink and downlink two
The number of subframes in a direction and the amount of corresponding flow are proportional, therefore uplink subframe and downlink subframe can show
Go out similar congestion level.
Then, trunking 121 is it needs to be determined that arrive the path loss of multiple terminal devices.Trunking 121 can pass through
It was found that signaling channel PSDCH or data channel PSSCH measures the path loss of terminal device.Trunking 121 is then true
Determine the required received signal power of multiple terminal devices.Then, based on identified path loss and received signal power come
Determine the transimission power P of each resource block RB for each terminal devicei, wherein i=1,2 ..., n.Needed for terminal device i
The number for the RB to be transmitted is RBi。
Then, trunking 121 is RB according to the number of identified RBi, terminal device is ranked up.According to transmission
The sequence RB of power1'≥RB2'≥...≥RBn', n terminal device be ranked into (TE 1 ', TE 2 ', TE by trunking 121
3'…TE n').Exist in the case of n≤W enough subframes for distribute in the case of, then by each terminal device
Resource block is separately dispensed into an individual subframe.In n>In the case of W, that is, it is not enough to distribute for each terminal device
In the case of individual subframe, W terminal devices are separately dispensed into individually before resource block number in n terminal device is come
Subframe in.
Trunking 121 needs the resource block by remaining (n-W) a terminal device to be separately dispensed into assigned W
In a subframe.At this moment, find a terminal device so that the number of its own data block to be transmitted with it is assigned
The summation of the total number of resource block is minimum, and at the same time meeting general power is less than or equal to Pt.Here general power refers to using
Required maximum transimission power is multiplied by RB in allocated resource blocki+RB(w+1)'。RBiExpression has been assigned to subframe i
In resource block number.After distributing (W+1) a terminal device, the total number of allocated data block is updated to
RBi+RB(w+1)'。
Then for remaining (n-W-1) a terminal device, operation identical with (W+1) a terminal device is executed to incite somebody to action
It is assigned in subframe.Finally, the resource block that n terminal device to be transmitted can be all grouped into W subframe.To Mr. Yu
A logic subframe, it can be randomly mapped in Q physical sub-frame one.For given physical sub-frame, random selection
The starting resource block distributed to multiple terminal devices, then continuously places RBiA resource block.
By above procedure, trunking 121 can as homogeneously as possible refer to the resource block of the terminal device linked
It sends in downlink subframe.Therefore, the interference relayed between cluster can be preferably randomized.By the process of randomization,
System performance can be promoted effectively.
