It is construed as limiting.
Embodiment 1,
Shown in reference picture 2, the embodiment of the present application provides a kind of available resources and determines method, applied to above-mentioned communication system
System, the method comprising the steps of S101-S103：
S101, the first UE obtain the 2nd UE semi-persistent scheduling (Semi-Persistent Scheduling, SPS) resource
Take transmission cycle and resource gravity treatment counter information.
Specifically, shown in reference picture 3, step S101 can include step S1011：
S1011, the first UE parse the 2nd UE physical shared control channel (Physical Sharing Control
Channel, PSCCH) obtain the letter of spatial channel information form (Space Channel Information, SCI Format) 1
Breath, wherein, the information of SCI Format 1 includes the 2nd UE SPS resource occupation transmission cycle and resource gravity treatment counter letter
Breath.
Specifically, it can be set in resource reservation (Resource reservation) domain of the information of SCI Format 1
SPS resource occupation transmission cycles；Resource gravity treatment counter information is set in the information of SCI Format 1, specifically, can make
Resource gravity treatment counter information is represented with the reservation bit of the information of SCI Format 1, or changes existing SCI Format 1
Form, increase special domain be used for represent resource gravity treatment counter information.
S102, the first UE detect the 2nd UE energy to determine in detection cycle the resource not taken by the 2nd UE.
First UE can determine second by way of detecting the 2nd UE reference signal energy and symbol gross energy
Whether UE takes corresponding resource.
Specifically, shown in reference picture 3, step S102 can include step S1021-S1023：
S1021, the first UE detect the 2nd UE reference signal ENERGY E in the resource in certain detection cyclefAnd symbol
Number gross energy Ec。
S1022, the first UE calculate energy measuring coefficientWherein,Ef,thresAnd Ec,thresFor energy measuring threshold value, μ is reference signal occupation proportion coefficient, ∪
Represent or operate.
Above-mentioned formula represents：WhenIn all values when being 0, then P=0, whenIn when to have a value be 1, then P=1.
S1023, the first UE selection P=0 resource are as the resource not taken by the 2nd UE.
First UE judges whether Current resource is taken by the 2nd UE, if P according to the 2nd UE energy measuring probability coefficent P
=1, then it represents that resource is occupied, if P=0, judges that resource is not taken by the 2nd UE.
S103, the first UE are according to the 2nd UE SPS resource occupation transmission cycle, resource gravity treatment counter information and detection week

With situation, the resource with reference to shared by the 2nd UE SPS resource occupation transmission cycles determine the 2nd UE periodic schedulings, with reference to
Two UE resource gravity treatment counter information further determines that the first UE available resources, and which is pattern 3 for the first UE
UE, the 2nd UE be pattern 4 UE, or, the first UE be pattern 4 UE, the 2nd UE be pattern 3 UE both of which fit
With solving it is determined that during available resources, the UE of pattern 3 and the UE resource occupation conflicts of pattern 4.
Optionally, the 2nd UE resource occupation precedence information and pattern information is also included in the information of SCI Format 1,
Resource occupation precedence information is used for the priority for indicating the 2nd UE distribution resources, and pattern information is used to indicate that the 2nd UE is pattern
The 4 UE or UE of pattern 3.
Specifically, 1 bit in the information reservation bits of SCI Format 1 can be used to represent UE pattern, such as with 0 table
Show pattern 3, with 1 intermediate scheme 4, or, with 1 intermediate scheme 3, with 0 intermediate scheme 4.
Further alternative, shown in reference picture 4, when the first UE is the UE of pattern 3, this method also includes step
S104 and S105：
S104, the first UE determine the UE that the 2nd UE is pattern 4 according to the 2nd UE pattern information.
The available resources of 2nd UE resource occupation precedence information and the first UE are sent to base station by S105, the first UE.
The step is used for base station and distributes resource according to the two information for the first UE of pattern 3.
Embodiment 2,
Exemplified by UE using the first UE as pattern 3, the 2nd UE are the UE of pattern 4, the embodiment of the present application provides another kind can
With resource determining method, shown in reference picture 5, this method includes：
S201, base station notify that the first UE is detected.
Base station can notify that all or part of first UE, the first UE are the UE of pattern 3.
S202, the first UE parse the information of SCI Format 1 in the 2nd UE PSCCH, obtain the 2nd UE pattern letter
Breath, resource occupation precedence information, SPS resource occupation transmission cycle and resource gravity treatment counter information, and according to the 2nd UE
Pattern information determine the 2nd UE be pattern 4 UE, then perform step S203, otherwise re-execute S202.
S203, the first UE detect the 2nd UE energy to determine in detection cycle the resource not taken by the 2nd UE.
The step is identical with S102, will not be repeated here.
S204, the first UE are according to the 2nd UE SPS resource occupation transmission cycle, resource gravity treatment counter information and detection week
