S503, terminal device determine the target sub- period.
Terminal device determines the target sub- period from the sub- period that first time period includes.Specifically, terminal device From the sub- period that the first part of first time period includes, the target sub- period is determined.For convenience of description, the target sub- time Section uses sSSTargetTo indicate.
In one implementation, terminal device can in the sub- period that the first part of first time period includes with Machine selects a sub- period as the target sub- period.Such as, it is assumed that first time period includes 4 sub- periods, is respectively Sub- period 0, sub- period 1, sub- period 2 and sub- period 3.Terminal device can choose the sub- period 1 as target Period.
In the second implementation, terminal device can also be according to certain rule, in the first part of first time period Including the sub- period in determine a sub- period as the target sub- period.The rule can be what agreement was fixed, or Person is configured by the high level of terminal device, or passes through physical layer control signaling, media access control (Media by the network equipment Access Control, MAC) layer control signaling or wireless heterogeneous networks (Radio Resource Control, RRC) layer Signal deployment.When the rule passes through rrc layer signal deployment by the network equipment, rrc layer signaling can be special RRC message, It is also possible to system broadcast message.The high level can be MAC layer, rrc layer or higher.It is not limited in the embodiment of the present invention System.
Based on second of implementation, terminal device can randomly choose a several i in the threshold value of pre-configuration, and i is certainly So number, and i≤pre-configuration threshold value.Terminal device is using the i-th sub- period in the first part of first time period as target The sub- period.Different terminal devices can configure different threshold values, be wanted with embodying the time delay of business of different terminal devices Ask different or business priority different.
Based on second of implementation, terminal device can star a counter (or timer).The counter is initial Value is 0.Counter starts counting first sub- period from the first part of first time period.It is every to pass through a sub- period, And terminal device does not listen to the occupied instruction letter of target frequency domain resource that other terminal devices are sent in the sub- period Breath, then counter adds 1.When counter reaches C or C-1, then terminal device determines that the sub- period is the target sub- period.To random The numerical value C of the selection or threshold value C of pre-configuration, or reaching randomly selected numerical value C-1 or the threshold value C-1, C of pre-configuration is terminal Equipment is randomly selected from 0 to N1 or C is to be pre-configured.C is natural number and 0≤C≤N1.Such as, it is assumed that C=2, and it is false If counter reaches 2, determine that the corresponding sub- period is the target sub- period.First sub- time segment counter is equal to 0.Such as Fruit terminal device does not listen to the occupied finger of target frequency domain resource that other terminal devices are sent in first sub- period Show information, then counter is added 1.Second sub- time segment counter is equal to 1.If terminal device does not have in second sub- period Have and listen to the occupied instruction information of target frequency domain resource that other terminal devices are sent, then counter is added 1;Third height Time segment counter is equal to 2.Terminal device determines that the third sub- period is the target sub- period.If listening to other ends The occupied instruction information of target frequency domain resource that end equipment is sent, terminal device can stop the counter.If listened to The occupied instruction information of target frequency domain resource that other terminal devices are sent, terminal device do not send information in this period. Such as, it is assumed that C=2, first sub- period listen to the occupied instruction of target frequency domain resource that other terminal devices are sent Information, then terminal device determines that target frequency domain resource is occupied by other terminal devices, then terminal device does not use the period Send information.
Based on second of implementation, terminal device can star a counter (or timer).The counter is initial Value is C.C is that terminal device is randomly selected from 0 to N1 or C is to be pre-configured.C is natural number and 0≤C≤N1.Counter It is started counting first sub- period from the first part of first time period.It is every to pass through a sub- period, and the period does not have Have and listen to the occupied instruction information of target frequency domain resource that other terminal devices are sent, then counter subtracts 1.When counter is passed When reducing to 0 or 1 or -1, terminal device determines that the sub- period is the target sub- period.Such as, it is assumed that C=2, first period of the day from 11 p.m. to 1 a.m Between segment counter be equal to 2.If terminal device does not listen to the target that other terminal devices are sent in first sub- period The occupied instruction information of frequency domain resource, then subtract 1 for counter.Second sub- time segment counter is equal to 1.If second son Period does not listen to the occupied instruction information of target frequency domain resource that other terminal devices are sent, then subtracts 1 for counter. The sub- time segment counter of third is equal to 0.Terminal device determines that the third sub- period is the target sub- period.If monitored The occupied instruction information of target frequency domain resource sent to other terminal devices, terminal device can stop the counter.Such as Fruit listens to the occupied instruction information of target frequency domain resource that other terminal devices are sent, and terminal device is not sent out in this period It delivers letters breath.Such as, it is assumed that C=2, it is occupied that first sub- period listens to the target frequency domain resource that other terminal devices are sent Instruction information, then terminal device determines that target frequency domain resource is occupied by other terminal devices, then terminal device does not use this Period sends information.
When C is to be pre-configured, the C can be what agreement was fixed, or be configured by the high level of terminal device, Huo Zheyou The network equipment is by physical layer control signaling, media access control (Media Access Control, MAC) layer control signaling, Or wireless heterogeneous networks (Radio Resource Control, RRC) layer signal deployment.When C passes through rrc layer by the network equipment When signal deployment, rrc layer signaling can be special RRC message, be also possible to system broadcast message.The high level can be MAC Layer, rrc layer or higher.The embodiment of the present invention with no restriction.
It should be understood that S502 and S503 sequence can exchange, the purpose of the embodiment of the present invention may be implemented.That is terminal Equipment can also first determine the target sub- period, then determine target frequency domain resource again.
In a kind of implementation, the processor 204 of terminal device can be used for determining the target sub- period.
S504, terminal device monitor the occupied instruction information of target frequency domain resource that other terminal devices are sent.
Instruction information instruction target frequency domain resource is occupied by other terminal devices.The instruction information is to provide with target frequency domain Source corresponds to any information (such as full 0) sent in frequency domain resource, which can not be decoded, and terminal device is only from the frequency Detect whether signal energy (or RSSI) is greater than or equal to some threshold value in the resource of domain, it can judge that the frequency domain resource is corresponding Whether target frequency domain resource is occupied by other terminal devices.When the first frequency domain resource is same on frequency domain with the second frequency domain resource When block resource (with frequency), terminal device can monitor the part that target frequency domain resource is located at the sub- period of first time period.Than Such as, terminal device according in target frequency domain resource received signal energy (or RSSI) whether be greater than or equal to threshold value Thfast_sesning, to determine whether to receive the occupied instruction information of target frequency domain resource.When the first frequency domain resource with For second frequency domain resource when corresponding on frequency domain, terminal device can monitor the first frequency domain money corresponding with target frequency domain resource Source.Such as, it is assumed that target resource is the second frequency domain resource 3, and corresponding is the first frequency domain resource 1, then terminal device according to Whether received signal energy (or RSSI) is greater than or equal to threshold value Thfast_sesning in the first frequency domain resource 1, comes true It is fixed whether to receive the occupied instruction information of the second frequency domain resource 3.Threshold value Thfast_sesning can be what agreement was fixed, Perhaps pass through physical layer control signaling, media access control (Media by the high-rise configuration of terminal device or by the network equipment Access Control, MAC) layer control signaling or wireless heterogeneous networks (Radio Resource Control, RRC) layer Signal deployment.When passing through rrc layer signal deployment, rrc layer signaling can be special RRC message, is also possible to system broadcasts and disappears Breath.The high level can be MAC layer, rrc layer or higher.The embodiment of the present invention with no restriction.
If the target sub- period is not first sub- period of the first part of first time period, terminal device exists On at least one sub- period before the target sub- period, the target frequency domain resource quilt that other terminal devices are sent is monitored The instruction information of occupancy.
If the target sub- period is first sub- period of the first part of first time period, terminal device is not required to Monitor the occupied instruction information of target frequency domain resource that other terminal devices are sent.At this point, terminal device executes S505, i.e., Target frequency domain resource directly, which is sent, in the part for being located at the target sub- period in target frequency domain resource occupies instruction information.
Terminal device is begun listening for from first sub- period, behind each sub- period will monitor, until monitor To the previous period of target sub- period, or until listening to the occupied instruction information of target frequency domain resource.
When terminal device determines target sub- period by second of implementation of step S503, terminal device can be with Instruction information is monitored on the sub- period before counter meets condition.Such as, it is assumed that counter uses plus coujnt, then exists When counter is less than C, terminal device monitors instruction information on the sub- period.Or, it is assumed that counter uses subtraction count, then When counter is greater than 0, terminal device monitors instruction information on the sub- period.
If the terminal determine that it is occupied to receive target frequency domain resource on sub- period before the target sub- period Instruction information terminates the operation of this period.For example, terminal device does not send the occupied instruction letter of target frequency domain resource Breath and/or terminal device cease listening for subsequent sub- period and/or the terminal device not in the second time period Information is sent in the target frequency domain resource.Such as, it is assumed that the current sub- period is sSSi, i=0,1 ... sSSTarget-1.Work as end End equipment received signal intensity instruction (RSSI) in target frequency resource, is greater than or equal to threshold value Thfast_sesning, then Terminate the operation of this period.
