Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
The advantages of to make technical solution of the present invention, is clearer, makees specifically to the present invention with reference to the accompanying drawings and examples
It is bright.
Embodiment one
The present embodiment provides a kind of distribution methods of communication resource, as shown in Figure 1, which comprises
101, first base station sends configuration information to user equipment (UE), so that the UE is used according to the configuration information
Ascending resource sends data or information to the first base station.
Wherein, the configuration information, which is used to indicate in ascending resource, reserves specified upstream resource, reserved specified upstream
Resource can be used for transmitting the communication information between the first base station and the second base station.In general, first base station and the second base
Communication between standing can be used some or all of reserved specified upstream resource, or can not make in some subframe
With reserved specified upstream resource.It should be noted that, although reserved specific resources can be used for transmitting first base station and the
Communication between two base stations, but for user equipment, the practical use for knowing reserved specific resource is not needed,
Or require no knowledge about whether genuine some or all of ascending resource is used for transmission leading between first base station and the second base station
Letter.For example, as shown in figure 8, each subframe of ascending resource is by intermediate PUSCH (Physical Uplink Shared in figure
Channel, Physical Uplink Shared Channel) and upper and lower ends PUCCH (Physical Uplink Control Channel,
Physical Uplink Control Channel) composition, PUSCH is for carrying upstream data.Wherein, dash area is reserved specified upstream money
Source.Specifically, specified upstream resource can be one or more OFDM symbols (or SC-FDMA symbol) in subframe, it is described
Specified upstream resource occupies part available bandwidth on frequency domain or occupies whole available bandwidths.Assuming that the resource that PUCCH is occupied
It cannot be occupied again by other channels, then in this example, available bandwidth refers to the band other than the resource that PUCCH is occupied
It is wide.For example, a part for the resource that PUSCH channel can be used can be used as reserved specified upstream resource.
Optionally, the specified upstream resource be located in ascending resource SRS (Sounding Reference Signal,
Detection reference signal) in resource.
Preferably, it allows the wider frequency domain resource of specified upstream resource occupation as far as possible, occupies relatively narrow time-domain resource.UE is being sent out
Specified upstream resource can be avoided by sending when data, map data on the ascending resource other than specified upstream resource.Assuming that base station is not
It can support to be received and emitted on the same carrier simultaneously, therefore when base station receives the signal of user equipment transmitting,
Another base station cannot be transmitted signals to simultaneously, even if using different frequency resources (for example, different radio resources
Block (Resource Block or Resource Block pair)) transmitting signal, it can not emit simultaneously.Therefore, in this hair
In bright, in the OFDM symbol (or SC-FDMA symbol) where reserved specified upstream resource, user equipment can not emit letter
Number.Therefore, for new version user equipment, in order to avoid influencing too much, the present invention was inclined to use on the time few as far as possible
Resource, but the resource in relatively more frequency is as reserved specific resources.Certainly, for existing version (or old edition
This, legacy) agreement user equipment, as long as ascending resource that user equipment transmitting signal occupies and reserved specified upstream money
It is orthogonal on source frequency, then big interference will not be caused to inter base station communication, be acceptable.Optionally, this is received in base station
It, can be in the OFDM except the OFDM symbol (or SC-FDMA symbol) where reserved resource when the uplink signal of a user
The data on a part of OFDM symbol (or SC-FDMA symbol) are received on symbol (either SC-FDMA symbol).What is done so is good
Place is, although performance has certain loss for the user equipment of legacy version agreement, only increases a bit to scheduler
Limitation will guarantee that the resource of legacy version user is orthogonal with reserved resource time-frequency, set without the user to legacy version agreement
Standby normal communication causes too much influence, such as cannot dispatch in entire subframe.Therefore, if reserving one on PUSCH
Component frequency resource and it is not all as reserved specific resources, then can influence to legacy version protocols User equipment it is fewer.
Further, after the first base station sends configuration information to user equipment (UE), the method also includes: institute
State first base station to the UE send scheduling instruction so that the UE according to the scheduling instruction use comprising it is described it is specific on
The ascending resource of row resource sends data to the first base station or uses except the orthogonal frequency where the specified upstream resource
The ascending resource divided other than multiplexing OFDM symbol (or SC-FDMA symbol) sends data to the first base station.Namely referring to
In the control channel for showing ascending resource distribution, such as in the PDCCH of carrying upstream allocation information (UL Grant), there can be information
To indicate whether specific ascending resource is used for the transmitting of this PUSCH channel.And the information of specific ascending resource, such as
The running time-frequency resource of occupancy can be notified in advance to user in high-level signaling as reserved resource, but using also in PUSCH
It is that can also further be indicated by the control channel of downlink, such as indicated by bit status information without using this resource
Using still not using.
102, first base station sends the communication information to second base station in the specified upstream resource.
Further, before the first base station sends the communication information to second base station, the method also includes:
The first base station sends the configuration information to second base station, so that second base station is according to the configuration information
The communication that the first base station is sent is received in the OFDM symbol (or SC-FDMA symbol) where the specified upstream resource
Information.
Specifically, the first base station includes: to UE transmission configuration information
The first base station by proprietary RRC (Radio Resource Control, wireless heterogeneous networks) signaling or
The RRC signaling of person's broadcast carries the configuration information, and the configuration information is sent to the UE.
Compared with prior art, the embodiment of the present invention is used this part ascending resource by reserving a part of ascending resource
The communication information between transmission base station；The configuration information of reserved specified upstream resource is sent to user equipment by first base station
UE；If reserved specific ascending resource is located at the latter one or several OFDM symbols (or SC-FDMA of a subframe
Symbol), then first base station can before subframe several symbols receive UE transmission data after, later on several symbols
The communication information is sent to the second base station using the specified upstream resource reserved in ascending resource, completes to hand over the information of the second base station
Mutually；In addition, first base station can send scheduling instruction to UE, dynamically indicate that UE uses reserved specified upstream resource.We
Method, as Backhaul, reserves the communication information that a part of ascending resource is used for transmission between base station using ascending resource, can
Enough guarantee the data transmission between UE and first base station, can also make to carry out the communication information between first base station and the second base station
Transmission.When needing more specified upstream resources to transmit for the data between base station, more specified upstreams can be reserved
Resource is used for transmission the communication information between base station；When reserved specific ascending resource does not need to be used for transmission between base station
When the communication information, relatively rapid it can be released to user equipment, the communication number being used for transmission between user equipment and base station
According to.Similar, reserved specified upstream resource is used as data transmission when needing more ascending resources to carry out data transmission,
When the ascending resource that data transmission occupies is less, more reserved ascending resource can be used and be used for transmission between base station
The communication information.

The first base station sends data.
Wherein, the specified upstream resource is one or more OFDM symbols (or SC-FDMA in ascending resource subframe
Symbol), the specified upstream resource occupies part available bandwidth on frequency domain or occupies whole available bandwidths.Optionally, institute
Specified upstream resource is stated to be located in detection reference signal SRS resource, if at this moment user equipment is using reserved specific resources,
What is sent can be SRS information.
Compared with prior art, the embodiment of the present invention is used this part ascending resource by reserving a part of ascending resource
The communication information between transmission base station；User equipment (UE) receives the configuration for the reserved specified upstream resource that first base station is sent
Information；UE sends data or SRS to first base station using suitable ascending resource according to configuration information, so that the first base
It stands, the specified upstream resource reserved in ascending resource can be used and send the communication information to the second base station, complete and the second base station
Information exchange；In addition, UE receives the scheduling instruction that first base station is sent, can dynamically be provided using reserved specified upstream
Source.This method, as Backhaul, reserves the communication letter that a part of ascending resource is used for transmission between base station using ascending resource
Breath can either guarantee the data transmission between UE and first base station, can also make to be led between first base station and the second base station
The transmission of letter information；When needing more specified upstream resources to transmit for the data between base station, can reserve more
Specified upstream resource is used for transmission the communication information between base station；When reserved specific ascending resource does not need to be used for transmission base
When the communication information between standing, relatively rapid it can be released to user equipment, be used for transmission between user equipment and base station
Communication data.Similar, reserved specified upstream resource is used as when needing more ascending resources to carry out data transmission
Data transmission can be used more reserved ascending resource and be used for transmission when the ascending resource that data transmission occupies is less

Embodiment three
The present embodiment provides a kind of distribution method of communication resource, the detection of reserved part or whole in ascending resource
Reference signal SRS resource, which is used as, coordinates channel, coordinates channel and is used for transmission the transmission base station and receives the communication between base station
Information, it is described it is some or all of can be it is some or all of in some subframe, in the communication system of the present embodiment
In include sending base station, receiving base station and user equipment (UE), UE is controlled by sending base station, as shown in Figure 3, which comprises
301, it sends base station and determines that the SRS resource of reserved part or whole is used as coordination channel.
For example, sending base station according to the data interaction amount between UE or reception base station, the SRS resource reserved is determined
Size, when send the data interaction between base station and UE it is more and send base station and receive base station information interaction it is less when,
Less SRS resource will be reserved and be used as coordination channel, more SRS resources are used to send the data between base station and UE and are passed
It is defeated；When send the data interaction between base station and UE it is less and send base station and receive base station information interaction it is more when, just
It reserves more SRS resource and is used as coordination channel, more detection resources are used to send base station and received between base station
Information transmission, as shown in figure 9, reserved SRS resource is the dash area in figure, SRS is located at the last one OFDM in subframe and accords with
Number (either SC-FDMA symbol) OFDM symbol (perhaps SC-FDMA symbol) is described occupied on frequency domain part available bandwidth or
