Detailed description of the invention

The embodiment of the present application will provide a kind of information processing method, be mainly used in non-stop layer node or centromere Point is not involved in the communication system that communication resource distribution controls, and the subscriber equipment of communication is divided into the first priority Subscriber equipment and the subscriber equipment of the second priority, described first priority be higher than the second priority；In order to Ensure that the subscriber equipment of the first priority has higher probability to compete resource and carries out business data transmission, described The subscriber equipment of the first priority will send right of way signal, the user of the second priority at the n-th-m communication cycle Equipment will determine whether to participate in the competition of the n-th communication cycle communication resource according to the right of way signal received Or use, or whether use the first probability low when not receiving described right of way signal to participate in described resource Competition etc..So can reduce the degree of contention of the user of the first priority, or the user of the second priority allows Going out the subscriber equipment that part or all of resource guarantees that priority is high preferentially uses these resources to transmit data.

Below in conjunction with Figure of description and specific embodiment technical scheme done and further explain in detail State.

Embodiment of the method one:

As it is shown in figure 1, the present embodiment provides a kind of information processing method, described method includes:

Step S110: determine the priority of subscriber equipment；

Step S120: if the priority of described subscriber equipment is the first priority and is predefined in the n-th communication cycle There is outgoing data, send right of way signal at the n-th-m communication cycle；

Wherein, described n is the integer not less than m；M is the integer more than or equal to zero.Described notice is believed Number for informing that the subscriber equipment of the first priority described in other subscriber equipmenies will participate in the money of the n-th communication cycle Source competition or use.

The priority of subscriber equipment is divided into the first priority and the second priority in the present embodiment.Described first The division of priority and the second priority can be according to the subscriber equipment attribute of subscriber equipment or subscriber equipment n-th Communication cycle needs the type of service of the data sent to determine.Described subscriber equipment attribute includes that user sets The group attribute of the group of standby device type, described subscriber equipment ownership and the type etc. of the communication standard of support Type parameter wherein one or more.

Described type of service difference includes: the communicating requirement of business is different, concrete as to when communicating admissible Ductility is different or QoS requirement is different or business importance is the most equal.Usual described admissible time delay Property the biggest, then the probability that priority is the second priority that may be corresponding is higher, when implementing, can be straight Connect and determine according to type of service.

Described priority can be to be set in advance in subscriber equipment, or is determined by the protocol layer of subscriber equipment, Can also obtain from the access node of described subscriber equipment.Described access node can be base station or other in The communication nodes such as heart node, can be used for described subscriber equipment and are linked into mobile network.Described access node can be led to Cross the transmission of configuration information to inform the priority of subscriber equipment.

After the priority of subscriber equipment determines, it is predefined in n-th as the subscriber equipment of the first priority determines Communication cycle carries out data transmission, then send right of way signal in the n-th-m cycle.Described right of way signal is with broadcast Form send, the most positioned adjacent other subscriber equipmenies participating in same resource contention can receive, The subscriber equipment facilitating the second priority determines resource contention and the use of the n-th communication cycle；Concrete as selected Avoidance mechanism determines resource contention or the use being not involved in the n-th communication cycle.So can reduce the n-th communication The resource contention in cycle or the severity of use conflict, it is ensured that the subscriber equipment of high priority has higher several Rate competition or use are to the communication resource.

The most described subscriber equipment generally can be D2D subscriber equipment or V2V subscriber equipment etc. should It is used in non-stop layer node or Centroid is not involved in the communication system of resource distribution.The resource competed can be Authorize frequency spectrum or the communication resource of unlicensed spectrum.

If described n-th-m communication cycle is current communication cycle, then the n-th communication cycle is current communication cycle M communication cycle afterwards.Described right of way signal can be used for the subscriber equipment of the second priority to determine that it is The relevant informations such as the resource contention of no participation the n-th communication cycle or resource contention parameter.

Assuming that the subscriber equipment being carrying out method described in the present embodiment is first user equipment, then in step If S110 presetting in described first user equipment information processing method first described in execution the present embodiment use The priority of family equipment, described step S110 can include from the storage position presetting described priority, reads The priority of described first user equipment, it is also possible to configure described priority from the protocol high layer of subscriber equipment, Or described first user equipment obtains described priority from the network equipment such as access node or Centroid, Can include receiving configuration information from network equipment, resolve configuration information and obtain the excellent of described first user equipment First level.When implementing, execution opportunity of described step S110 can be that described first user equipment determines When n-th communication cycle has data to send, take to determine the priority of described first user equipment.Described net Network side apparatus can also be the network node on evolved base station eNB, small-cell base station or more upper strata, such as net Close, or the network equipment such as Mobility Management Entity MME.It should be noted that: first user here sets For referring to any one subscriber equipment.

In the step s 120, when the priority determining described first user equipment is the first priority and determines There are data to be sent at the n-th communication cycle, then send described right of way signal at the n-th-m communication cycle.

Described right of way signal is preferably energy signal, and when described right of way signal is energy signal, second is preferential The UE of level detects the energy of described right of way signal, is not resolving the specifying information content of described right of way signal On the premise of, just can determine that the UE of described first priority have sent right of way signal, participation n-th is led to The resource contention in letter cycle and use.Described right of way signal can also be for the control information content of short-range communication A part.Here short-range communication can include D2D communication, V2X communication.Described V2X is vehicle The abbreviation of to Everything, corresponding Chinese can be car connected network communication.

The UE of the most described first priority can be at any one number of the n-th-m communication cycle Described right of way signal is sent according in frame, subframe or transmission symbol.The UE of the first priority can be by being No transmitting information on the running time-frequency resource specified represents whether it has the transmission of right of way signal, it is also possible to Any running time-frequency resource of any n-th-m communication cycle sends described right of way signal, if be that right of way signal is permissible Represented by described information content.

The mode sending right of way signal in the step s 120 has multiple, several sides realizing simplicity introduced below Formula.

Mode one:

Described step S120 includes:

When one, the synchronization subframe of a length of 1ms generally includes the time slot of a length of 0.5ms when 2；And each Time slot includes 6 or 7 transmission symbols, and described transmission symbol can OFDM symbol or SC-FDMA symbol. Described OFDMA is the abbreviation of Orthogonal-Frequency Division Multiplexing, in correspondence Literary composition is OFDM.Described SC-FDMA is Single Carrier Frequency Division The abbreviation of Multiplexing, corresponding Chinese is single-carrier frequency division multiple access.

The one of the sub-frame formats for synchronizing subframe shown in Fig. 2；The 1st of 1st time slot in fig. 2 With the master sync signal PD2DSS communicated for D2D of transmission in the 2nd transmission symbol；2nd time slot 4th transmits, with the 5th, the auxiliary synchronous signal SD2DSS communicated for D2D transmitted in symbol.At figure In 2, the 0th the transmission symbol at the 1st time slot synchronizing subframe transmits described right of way signal (Announce Signal, AS).

It should be noted that: the time-domain position of AS is not limited to synchronize first character position of subframe, the most not Restriction only takes up a symbol.The frequency domain bandwidth of AS signal can be 6 identical with synchronizing signal Resource Block RB, it is also possible to for other all or part of available bandwidths.The resource location of AS can be joined by network equipment Put or pre-configured method determines.Network equipment herein can be access node, such as subscriber equipment, etc. Equipment.

In this embodiment, described resource preempt-mode at least includes the first priority users equipment UE Send right of way signal in the AS resource synchronizing subframe, need the UE detecting AS monitor and detect AS channel. Need exist for detecting the UE of described AS and can include that any one does not send the UE of described AS, but at least UE including the second priority.

Utilizing synchronization subframe to send right of way signal, described synchronization subframe is the subframe sending synchronizing signal, or It is configured with the subframe synchronizing sub-frame resources.Utilize synchronization subframe to send right of way signal, the most at least can be divided into two The pattern of kind:

Pattern one:

The described synchronization subframe utilizing described n-th-m communication cycle sends described right of way signal, including:

Form right of way signal；

It is right of way signal in fig. 2 and individually occupies the running time-frequency resource of described synchronization subframe, the most not with other The information such as synchronizing sequence carry out the multiplexing of running time-frequency resource.

Pattern two:

Described synchronization subframe is the subframe for sending synchronizing sequence；

Described first kind synchronizing sequence is applied not only to carry out the synchronization between subscriber equipment, is additionally operable to first preferential The subscriber equipment of other subscriber equipmenies the such as second priority informed by the subscriber equipment of level, the of transmission right of way signal The subscriber equipment of one priority will participate in the resource contention of the n-th communication cycle, allows the user of the second priority set Alternative is dodged resource contention or adjusts the probability etc. participating in competition.

When implementing, described utilize subframe send first kind synchronizing sequence include: generate the first kind synchronize The step of sequence.Subscriber equipment generates the mode of synchronizing sequence and at least includes two kinds, when subscriber equipment is first The subscriber equipment of priority and when needing to send right of way signal, selects the second to generate the mode of synchronizing sequence, The first is otherwise selected to generate the mode of synchronizing sequence；The second generates mode and the first life of synchronizing sequence The synchronizing sequence becoming the mode synchronized to generate is different.

Synchronizing sequence is divided into main synchronizing sequence and secondary synchronization sequences, the most described first kind synchronizing sequence It is preferably the subclassification to described secondary synchronization sequences with Equations of The Second Kind synchronizing sequence.

Generally synchronizing sequence can be made up of multidigit, wherein, and the value for even bit that d (2n) represents；d(2n+1) The value of the odd bits represented；The value of described n is from 0 integer started.DescribedWithIt is two Individual different cyclic shift M sequence；Described c₀(n) and c₀N () is two different scramble sequence； WithIt is two different scramble sequence.The concrete composition of M sequence and scramble sequence may refer to long-term In evolution LTE system, the definition in secondary synchronization sequences, describes the most in detail at this.

The mode of the first the first generation synchronizing sequence above-mentioned represented in described formula；The second represents The mode of synchronizing sequence is generated for the second.

During concrete implementation, it is also possible in advance for having previously generated described synchronizing sequence, carrying out together When step sequence sends, according to the priority of described subscriber equipment and the need of at the n-th communication cycle number Also may be used according to selecting the mode of a sequence from first kind synchronizing sequence or Equations of The Second Kind synchronizing sequence.If it is described The priority of subscriber equipment is the first priority and needs to send data at the n-th communication cycle, then select first Homochronousness sequence, otherwise selects Equations of The Second Kind synchronizing sequence.

Mode two:

Described step S120 comprises the steps that

Described data burst is the subframe of transmission business datum.Described appointment transmits symbol last biography optional Defeated symbol.It is that transmission is described on last transmission symbol of data burst at the data burst shown in Fig. 3 Right of way signal.Described appointment transmission symbol can also is that other transmit symbol, such as first transmission symbol etc..

Being only one, the position in data burst of AS example shown in Fig. 3, AS is positioned at data burst Later character position, it is also possible to redefine other symbols and send for AS signal.The time domain of AS signal is held A length of t (t is less than or equal to a transmission symbol duration) time continuous.Frequency domain bandwidth is not restricted, at available bandwidth In the range of.Time span t that in Fig. 3, the AS of empty wire frame representation takies, it is clear that less than a transmission The time span of symbol.

Mode three:

Described right of way signal includes that at least one notices flag；

Described n-th-m communication cycle send right of way signal, including:

The SA subframe utilizing the n-th-m communication cycle sends notices flag.

Described SA is the abbreviation of Schedule Assignment, and corresponding Chinese is dispatching distribution；Described SA Subframe is to control the subframe that channel sends, and is the subframe carrying dispatching distribution SA information, concrete as at D2D In communication, described control channel is PSCCH channel；Described PSCCH is Physical Sidelink Control The abbreviation of Channel, corresponding Chinese is that D2D communication physical controls channel.

Described notice flag can be to take a bit or multiple bit or implicit indication, notices mark when described When knowledge position is only a bit, the value of this bit is that the first user of the first priority of 1 or 0 correspondence sets Whether standby have data two kinds of different conditions to be sent at the n-th communication cycle.

The most such as, right of way signal (AS) is defined on the later m-th communication cycle of current period has business to need The first priority UE asked in current communication cycle in SA content (PSCCH channel) send AS.Its In, AS comprises 1bit, and 1 represents the resource seizing the later m-th communication cycle of current period, and 0 represents Do not seize the resource of the later m-th communication cycle of current period.The form that SA definition is new, increases AS Identification field (ASFlag, 1bit), is used for sending AS.

The resource distribution of communication has periodically, each communication cycle, and UE is first at SA resource pool in communication Upper transmission SA schedule information.In this embodiment, the first priority UE has business to send out at the n-th communication cycle Sending demand, then the SA form of optional new definition, the ASFlag territory of the SA content in current period is sent out Send AS.Carry the SA of AS, can be the scheduling SA of the data of the n-th-m communication cycle, it is also possible to individually Send a SA, but it is not used to indicate the data of the n-th-m communication cycle to transmit, further, can Think that this type of is specifically used to send the SA of AS information at running time-frequency resource special defined in SA subframe.

The UE needing to detect AS defined above, if it find that in the SA content received, ASFlag territory It is 1, then it represents that have the first priority UE to participate in the resource contention of the n-th communication cycle, then low priority UE Resource contention or the use in the n-th cycle can be abandoned, or select to participate in resource contention, p with relatively low Probability p Less than or equal to 1.

Additionally, in new SA form, the territory (Priority Area, PA) representing service priority can be defined, The UE needing to detect AS defined above, can be according to this PA information, it is judged that whether oneself participates in n-th The resource selection in cycle.

In this embodiment, described resource contention mode at least includes that the first priority UE sends and carries The SA form of AS information (ASFlag), needs the UE detecting AS to receive SA, finds ASFlag territory It is 1, then abandons the resource occupation in the n-th cycle or take money with relatively low probability selection, i.e. vacate more Resource is used by the first priority UE.

Described step S120 comprises the steps that the information content according to described right of way signal, determines transmission dispatching distribution The running time-frequency resource of SA information；

Such as, when the notice that described right of way signal is corresponding is designated 1, then SA subframe provides at the first time-frequency Source sends SA information, if described notice is designated 0, then sends SA information at the second running time-frequency resource, or If person does not receive SA on the first running time-frequency resource, then it is assumed that notice and be designated 0.Described first running time-frequency resource With the Resource Block that the second running time-frequency resource is ad-hoc location in SA resource pool, such UE can be according to sending SA Running time-frequency resource position determine described notice mark, i.e. determine the information content of described right of way signal.

Embodiment of the method two:

As it is shown on figure 3, the present embodiment provides a kind of method described in information processing method to include:

Step S210: determine the priority of subscriber equipment；

Step S220: if the priority of described subscriber equipment is the second priority, examines at the n-th-m communication cycle Survey the right of way signal that the subscriber equipment of the first priority sends；

Step S230: according to described right of way signal, determine resource contention or the use of described n-th communication cycle Relevant information.Described n is the positive integer not less than m；Described m is the integer more than or equal to zero.

Method described in the present embodiment is to apply in the subscriber equipment of the second priority.

N herein is as embodiment of the method, and choosing can be the integer not less than 2, described communication cycle Counting can be from the beginning of 1.The UE of described second priority it is preferably in the n-th communication week in step S220 When there are data to be sent phase, then at right of way signal described in the n-th-m cycle detection, to reduce the detection time of UE Number, saves the power consumption of UE.

In relevant information described in step S230, the initial time of the resource contention redefined can be included, The concrete initial time carrying out resource contention at the n-th communication cycle as the most predetermined in amendment, is modified to the n-th+i Individual communication cycle carries out resource contention.Described i is the integer not less than 1, now, it is clear that the second priority Subscriber equipment will dodge the subscriber equipment of described first priority at the n-th communication cycle.Additionally, second The subscriber equipment of priority can also directly carry out dodging the determination exiting the resource contention time, it is determined whether adopts Communicate with other communication modes, as transferred to send data etc. by modes such as base stations to target UE. Additionally, described step S230 may also include that when described right of way signal shows that the user of described first priority sets For when will participate in described n-th communication cycle resource contention or use, participate in described n-th communication with the first probability The competition of cycle resource or use；Wherein, when not receiving described right of way signal or described right of way signal shows When the subscriber equipment of described first priority will not participate in described n-th communication cycle resource contention or uses, institute The subscriber equipment stating the second priority will participate in the competition of described n-th communication cycle resource or makes with the second probability With；Described first probability is less than described second probability.The maximum occurrences of described second probability can be 1.Described First probability and the second probability can be configured by the Centroids such as base station or network equipment, it would however also be possible to employ The pre-configured mode of subscriber equipment configures.Such as, described right of way signal includes noticing flag, if described Notice the UE that flag is 1 expression the first priority and participate in competition or the use of the n-th communication cycle resource, Then the UE of the second priority is after receiving described right of way signal, participates in for the n-th communication week with the first probability The competition of phase resource or use, otherwise will participate in the n-th communication cycle money with the second probability higher than the first probability The competition in source or use.

Described step S220 comprises the steps that the synchronization subframe detecting described n-th-m communication cycle；And from described Synchronize to obtain described right of way signal in subframe.

Herein, the detection to described right of way signal can be in corresponding aforesaid mode one；And connect from synchronization subframe The collection of letters number is the most at least divided into following two mode.
