Embodiment
With the continuous evolution of communication protocol, need to introduce new function in communication system, such as support the functions such as positioning.
When introducing New function, base station usually requires the part physical resource using some UE.
However, existing UE cannot be distinguished by base station because introducing physical resource used in New function, this can not only be limited newly
The introducing of function, can also cause very big interference to UE decoding sometimes, reduce UE communication quality.
In view of the above-mentioned problems, The embodiment provides a kind of collocation method of physical resource, it is reserved by setting
Resource so that UE is when the ascending physical signal resource configured is overlapped with reserved resource and (usually partially overlapped), using being configured
Ascending physical signal resource in other resource transmission upstream datas in addition to reserved resource, keep reserved resource to be not used so that
New function can be introduced in a communications system using the reserved resource, improve the characteristic of UE forward compatibilities.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment explain.

Step：
Step 11, when receiving ascending physical signal resource allocation information, obtained based on the ascending physical signal resource allocation information
Take the ascending physical signal resource that base station is configured.
In specific implementation, base station is before UE will transmit upstream data, it will usually configure corresponding ascending physical signal money for UE
Source.
Step 12, when acquired ascending physical signal resource is overlapped with reserved resource, the acquired ascending physical signal money of selection
Other resource transmission upstream datas in source in addition to reserved resource.
In specific implementation, it can include in the reserved resource allocation information：The positional information of the reserved resource.Than
Such as, Physical Resource Block or resource element (Resource Element, RE) in the subframe or time slot shared by the reserved resource
Identification information.
In specific implementation, subframe or time slot shared by the reserved resource can be sub-frame of uplink or ascending time slot,
Can also be descending sub frame or descending time slot, can also both include sub-frame of uplink or ascending time slot, again including descending sub frame or under
Row time slot.
In specific implementation, the reserved resource can be obtained in several ways.In one embodiment of this invention, may be used
To obtain the reserved resource based on the reserved resource allocation information obtained in advance.
In specific implementation, the reserved resource allocation information is obtained in the system message that can be sent from base station.Such as,
In LTE system, MIB (Master Information Block), the SIB (System that can be sent from base station
Information Block) the reserved resource allocation information is obtained in the system message such as 1 or SIB2., can be with 5G systems
What base station was sent obtains described from the system messages such as Minimum SI (Minimum System Information Blocks)
Reserved resource allocation information.Base station can indicate which of which subframe or time slot thing by the reserved resource allocation information
Reason resource block or resource element are reserved resources.
In specific implementation, the reserved resource distribution letter is obtained in the common control channel order that can also be sent from base station
Breath.Such as, when the subframe of the reserved resource occupation is sub-frame of uplink or time slot, base station can pass through all UE or one
Radio Network Temporary Identifier (Radio Network Temporary Identifier, the RNTI) scrambling that group UE would know that
Descending control signaling sends the reserved resource allocation information.When the subframe of the reserved resource occupation is descending sub frame or time slot
When, the descending control signaling for the RNTI scramblings that base station can be would know that by all UE or one group of UE sends described reserved
Resource allocation information.Base station can indicate which Physical Resource Block (or Physical Resource Block by the reserved resource allocation information
It is right) it is the reserved resource, which RE is either indicated for the reserved resource or indicates which Physical Resource Block (or physics
Resource block to) which of symbol or subcarrier be the reserved resource.
In specific implementation, reserved resource is indicated in each subframe or time slot by common control channel order, can be caused
The instruction of reserved resource is dynamic.Also, make indicated reserved resource to be only applicable to currently by common control channel
Subframe or time slot, can also be applicable multiple subframes or time slot, until base station passes through the new reserved resource of common control channel order modification.
In specific implementation, the dedicated signaling for being used to indicate the reserved resource allocation information that can also be sent from base station
It is middle to obtain the reserved resource allocation information.Now, UE is generally in connected state.Such as, base station can pass through Radio Resource control
Make (Radio Resource Control, RRC) and send the reserved resource allocation information.The reserved resource can be provided with physics
Source block (or Physical Resource Block to) indicates for unit or in units of resource element.
In specific implementation, the reserved resource allocation information can also include：The configuration cycle letter of the reserved resource
Breath.The configuration cycle of the reserved resource can be predetermined number subframe or predetermined number time slot etc..According to described pre-
The configuration cycle information of resource is stayed, UE can know the interval duration between adjacent reserved resource.Such as, with the reserved resource
Position be the 1st~2 Physical Resource Block in subframe, and the configuration cycle of the reserved resource is exemplified by 3 subframe, then from son
Frame 0 starts, the subframe where 3 subframes are the reserved resource, and the 1st in the subframe where the reserved resource~
2 Physical Resource Block are the reserved resource.
In specific implementation, acquired ascending physical signal resource may be overlapped with reserved resource part, or be completely superposed,
Or it is misaligned.When the ascending physical signal resource of acquisition is overlapped or is completely superposed with reserved resource part, UE is needed from being obtained
Reserved resource is removed in the ascending physical signal resource taken, upstream data is transmitted using only surplus resources.Such as, base station is what UE was configured
Ascending physical signal resource includes 3 Physical Resource Block (or Physical Resource Block to), one of Physical Resource Block (or Physical Resource Block
It is right) or the part resource element of one of Physical Resource Block (or Physical Resource Block to) belong to reserved resource, then UE only makes
The fractional transmission upstream data overlapped with being removed in 3 Physical Resource Block (or Physical Resource Block to) with reserved resource.
In specific implementation, the UE of current version once receives the configuration of reserved resource, just without using reserved resource, than
Such as, UE can not measure the cell reference signals included in reserved resource in cell measurement procedure is performed.And for introducing
UE after New function or protocol version renewal, base station can dispatch UE by dedicated signaling and use the reserved resource, thus
UE forward compatibility characteristic can be improved.
In another embodiment of the invention, reference picture 2, methods described may include steps of：
Step 21, when receiving ascending physical signal resource allocation information, obtained based on the ascending physical signal resource allocation information
Take the ascending physical signal resource that base station is configured.

It is right) in other resource elements in addition to reserved resource to UE transmit data when, UE can completely parse downlink data, now institute
Stating in reserved resource allocation information can not include in downlink physical resource in addition to the reserved resource on other physical resources
Ratio value (being 100%) for transmitting downlink data.
When the reserved resource takes larger ratio in corresponding Physical Resource Block (or Physical Resource Block to),
If the data block size that base station can be effectively transmitted also according to complete Physical Resource Block (or Physical Resource Block to) is to UE
Data are transmitted, UE can not completely parse downlink data, therefore base station can be indicated except described reserved by reserved resource allocation information
It is used for the ratio value for transmitting downlink data outside resource in other physical resources.Such as base station sends physical down control to some UE
Signaling processed, informs that UE to UE will send data on 4 Physical Resource Block (or Physical Resource Block to), but 4 physical resources
The ratio reserved in block (or Physical Resource Block to) shared by resource is very big, now base station need to indicate except the reserved resource it
It is used for the ratio value for transmitting downlink data on outer other physical resources, such as 60%, script base station can pass through 4 complete physics
Resource block (or Physical Resource Block to) transmits 1000 bit datas to UE, and now UE is it needs to be determined that the data block of base station actual transmissions
Size is 1000*60%=600 bits.
