Embodiment
In the embodiment of the present invention, it is time-multiplexed from Traffic Channel, the angle of frequency division multiplexing and the multiplexing of discrete time-frequency provides The Resource Allocation Formula of down control channel, can solve the problem that due to TTI shorten may cause the problem of.
In the prior art, PDCCH and other channels carry out resource allocation by way of the time-division.But this mode for For sTTI there is resource utilization it is too low the problem of, this is described as follows.
For LTE-TDD systems, it supports the TTI (7 OFDM symbols) of 0.5ms length, and 2 OFDM symbols are grown The PDCCH of degree needs to take the resource of whole TTI 28.6% (2/7), along with the pilot tone measured for data demodulation, Transfer resource in TTI for data transfer is less than 70%.
And for LTE-FDD systems, because it supports that TTI shortest length is 2 OFDM symbols, therefore its resource Utilization rate is lower.
To improve resource utilization, the resource indicating method of first embodiment of the invention, for network side equipment, such as Fig. 1 Shown, the resource indicating method includes：
Step 101, the frequency domain character and temporal signatures of a transfer resource for being designated as down control channel distribution are determined Resource location indicates parameter；
Step 102, transmit the resource location and indicate parameter to mobile communication terminal, instruction mobile communication terminal is according to institute State the frequency domain character indicated by resource location instruction parameter and temporal signatures determine the transfer resource.
Unlike the prior art, in the resource indicating method of first embodiment of the invention, network side transmits in instruction During resource, no longer indicated with single frequency domain character or temporal signatures, but parameter is indicated simultaneously by resource location The frequency domain character and temporal signatures of transfer resource are indicated, this has been considerably improved the flexibility of transfer resource distribution, different fingers The mode of showing can solve the problem that the problem of different, and this is respectively described below.
When the method for the embodiment of the present invention is applied to the scene that the transfer resource is distributed using time division multiplexing mode, due to Resource location instruction parameter is not only able to indicate which symbol transfer resource is located at, while can also indicate that transfer resource exists Bandwidth on symbol, that is to say, that the resource of the down control channel of distribution no longer takes all bandwidth on frequency domain, but All or part of bandwidth can be used on frequency domain.And distribution of the transfer resource on frequency domain indicates to join by resource location Count to determine.
Therefore, using the resource indicating method of first embodiment of the invention, it can distribute and meet on frequency domain as needed The fractional bandwidth of data transfer demands carrys out bearing downlink control channel, and remaining part may be used as other purposes, improves The utilization rate of resource.
In the specific embodiment of the invention, above-mentioned transfer resource can be it is continuously distributed on frequency domain or from Distribution is dissipated, and different forms needs to design different resource location instruction parameters to indicate the distribution on frequency domain, to this point It is not described as follows.
<For down control channel distribution transfer resource on frequency domain it is continuously distributed>
When being the transfer resource that down control channel distributes when continuously distributed on frequency domain, there are several ways to indicate to pass Distribution of the defeated resource on frequency domain, such as：
1st, last part in a part or bandwidth will most be started by giving tacit consent in bandwidth distributes to down control channel, in frequency On domain, resource location instruction parameter only needs the bandwidth parameter for including indicating the bandwidth of the transfer resource；
This mode can simplify the design of frequency domain parameter.
2nd, on frequency domain, resource location instruction parameter (is used to determine the transfer resource in frequency including frequency point parameters simultaneously Starting point and/or terminal on domain) and bandwidth parameter；
Under this mode, the part for being capable of the flexible arbitrary continuation in nominated bandwidth distributes to down control channel, Improve the flexibility of resource allocation.
But regardless of mode, on frequency domain, the bit number of resource location instruction parametric distribution is more, then it can be carried For more diversified allocative decision, it is described as follows so that the width of down control channel is 1 OFDM symbol as an example.
It is assumed that acquiescence will most start a part and distribute to down control channel in bandwidth, then when resource location instruction parameter is used In instruction transfer resource when the bit number of the field of the distribution on frequency domain is 2,4 kinds of bandwidth occupancy ratios can be indicated, and are worked as When bit number is 3, then 8 kinds of bandwidth occupancy ratios can be indicated.
<For transfer resource discrete distribution on frequency domain of down control channel distribution>
When for the transfer resource that down control channel distributes in discrete distribution on frequency domain, also there are several ways to indicate Distribution of the transfer resource on frequency domain, such as：
1st, transfer resource is uniformly distributed on frequency domain, then on frequency domain, resource location instruction parameter is required to indicate Point, number of fragments and section gap.
2nd, transfer resource uneven distribution on frequency domain, then on frequency domain, resource location instruction parameter is required to indicate Bandwidth granularity between starting point, the bandwidth and adjacent sectional of each segmentation.
3rd, on frequency domain, resource location instruction parameter directly indicates the beginning and end of each segmentation.
Comparatively, for down control channel distribution transfer resource on frequency domain discrete distribution with bigger flexible Property, but it needs more expenses to carry out transfer resource position instruction parameter, and system design can select suitably to pass according to demand Defeated resource distribution mode.
In the specific embodiment of the invention, the specific implementation of bandwidth parameter is not limited, such as can be the transmission The bandwidth and the ratio of total bandwidth that the actual bandwidth taken of resource or description actually take, can also be others side Formula, such as on frequency domain, the bandwidth of the transfer resource and the ratio of total bandwidth are described using bandwidth parameter, this mode is with smaller Expense realize for down control channel distribution transfer resource bandwidth flexible configuration, be exemplified below.
It is assumed that when frequency domain parameter is 2bit, the width of down control channel is 1 OFDM symbol, and assignment 00 represents full band Width, assignment 01 represent 1/2 bandwidth, and assignment 10 represents 1/3 bandwidth, and assignment 11 represents 1/4 bandwidth, as shown in the table.
The assignment of bandwidth parameter The bandwidth of down control channel
00 Full bandwidth
01 1/2 bandwidth
10 1/3 bandwidth
11 1/4 bandwidth
In first embodiment of the invention, the down control channel can include one or more in time domain and (be more than or wait In 2) resource units, the resource units are OFDM symbol herein, but the embodiment of the present invention is not limited thereto.
To reduce expense, in first embodiment of the invention, when down control channel includes multiple (being more than or waiting in time domain In 2) resource units when, the bandwidth parameter is used for the band for indicating that resource units in the multiple resource units take Width, and other resource units acquiescence in the multiple resource units takes whole bandwidth.
It is which that aforesaid way, which also needs to increase a field come the resource units indicated in the multiple resource units, One resource units, it is contemplated that expense, in first embodiment of the invention, it can arrange in network side and end side, it is the multiple A resource units in resource units are last in the multiple resource units.
I.e. when bandwidth parameter is 2bit, when the width of down control channel is 2 OFDM symbols, the implication of assignment is as follows Shown in table.
Bandwidth parameter assignment The bandwidth of down control channel
00 First OFDM symbol full bandwidth, second OFDM symbol full bandwidth
01 First OFDM symbol full bandwidth, second bandwidth of OFDM symbol 1/2
10 First OFDM symbol full bandwidth, second bandwidth of OFDM symbol 1/3
11 First OFDM symbol full bandwidth, second bandwidth of OFDM symbol 1/4
It is of course also possible to which the different various information summaries of the width of down control channel are considered, resource location is such as set Instruction parameter is 3bit, and the implication that can be represented after resource location instruction parameter assignment is as follows：
000, the width corresponding to down control channel is the situation of 1 OFDM symbol, and down control channel takes entirely Bandwidth；
001, the width corresponding to down control channel is the situation of 2 OFDM symbols, and down control channel takes the The full bandwidth of one symbol, take the full bandwidth of second symbol；
010, the width corresponding to down control channel is the situation of 1 OFDM symbol, and down control channel takes 1/2 Bandwidth；
011, the width corresponding to down control channel is the situation of 2 OFDM symbols, and down control channel takes the The full bandwidth of one symbol, take 1/2 bandwidth of second symbol；
100, the width corresponding to down control channel is the situation of 1 OFDM symbol, and down control channel takes 1/3 Bandwidth；
001, the width corresponding to down control channel is the situation of 2 OFDM symbols, and down control channel takes the The full bandwidth of one symbol, take 1/3 bandwidth of second symbol；
110, the width corresponding to down control channel is the situation of 1 OFDM symbol, and down control channel takes 1/4 Bandwidth；
111, the width corresponding to down control channel is the situation of 2 OFDM symbols, and down control channel takes the The full bandwidth of one symbol, take 1/4 bandwidth of second symbol.
It can be found that above-mentioned resource location instruction parameter not only indicates temporal signatures (such as 000 expression of transfer resource Select first symbol), further indicates transfer resource frequency domain character (such as 111 can indicate take second symbol 1/4 band It is wide), therefore more flexible allocative decision can be realized than prior art.
