Below in conjunction with attached drawing, technical solution in the embodiment of the present invention is described.
The embodiment of the present invention can be adapted for any terminal device to the communications framework of terminal device.For example, vehicle is to vehicle (Vehicle to Vehicle, V2V), vehicle to other equipment (Vehicle to Everything, V2X), terminal-to-terminal service (Device to Device, D2D) etc..That is, the system framework of car-mounted terminal shown in fig. 1 or fig. 2 to car-mounted terminal is only an example of the embodiment of the present invention, the embodiment of the present invention is without being limited thereto.
Wherein, the terminal device in the embodiment of the present invention can be any device configured with physical layer and media access control layer, and terminal device is alternatively referred to as access terminal.For example, user equipment (User
Equipment, UE), subscriber unit, subscriber station, movement station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless telecom equipment, user agent or user apparatus.Access terminal can be cellular phone, wireless phone, session initiation protocol (Session Initiation Protocol, SIP) phone, wireless local loop (Wireless Local Loop, WLL it) stands, individual digital linear process (Personal Digital Assistant, PDA), the handheld device with wireless communication function, calculate equipment or the other linear processing devices, mobile unit, wearable device that are connected to radio modem etc..The embodiment of the present invention is illustrated by taking car-mounted terminal as an example, and but it is not limited to this.
Fig. 3 is the schematic flow chart that the terminal device of the embodiment of the present invention listens to the method for resource pool.
As shown in Figure 3, it is assumed that each carrier wave corresponds at least one sidelink process (sidelink process).For example, being the corresponding two sidelink processes of a carrier wave in 3GPP rel-14.When having new data packet to reach in moment n, terminal device needs to carry out resource selection, and terminal can carry out resource selection according to the intercepted result in the past period (for example, 1s) in the section [n+T1, n+T2].Specifically, terminal device can detect that the information of the corresponding channel quality of resource chooses resource in selection window by listening in window.
Wherein, T1≤4ms；20ms≤T2≤100ms.
Furthermore, the corresponding channel quality information of resource can be physics skidding control channel (Physical Sidelink Control Channel, PSCCH) corresponding physics skidding shares channel (Physical Sidelink Shared Channel, PSSCH channel quality (for example, receiving power or the quality of reception)).Terminal device can also be by carrying out received signal strength indicator (Receive Signal Strength Indicator to the resource in the sets of transmission resources, RSSI it) detects, obtains the information of the corresponding channel quality of each resource in the sets of transmission resources.
It should be noted that the value range of the T1 and T2 is only as an example, the present embodiment should not limit.
Since the business in car networking system has periodic feature.Therefore, in the embodiment of the present invention, terminal device can be by the way of semi-static transmission.
Specifically, being transmitted when terminal device has chosen a resource, then the terminal device persistently use can reserve this resource Cresel times, every transmission primaries data, Cresel subtract 1, when Cresel reduces to 0, terminal can generate one [0 at random, 1] random number between, and compared with parameter (probResourceKeep), if it is greater than the parameter, terminal carries out resource gravity treatment, if it is less than the parameter, terminal continues to use the resource, and resets Cresel.
In other words, the terminal device of the embodiment of the present invention can carry the information of reserved next transfer resource in the control information of this transmission, so that other terminal devices can be by detecting the terminal device
Control information judges whether this block resource is reserved and used by the terminal device, achievees the purpose that reduce resource contention.In other words, the terminal device of the embodiment of the present invention, can be by the resource of lasting use in multiple transmission cycles, to reduce the probability of resource gravity treatment and resource contention after choosing a transfer resource.
It should also be understood that can directly select resource when terminal device chooses resource in selecting window, the resource of a certain kind TTI can also be selected in the resource of a variety of TTI.The present invention is not specifically limited.
For example, the terminal device can select at least one resource in selection window according to the channel quality information of each resource.In another example the terminal device can also select the resource of the first TTI from the resource of a variety of TTI according to the information of the corresponding channel quality of resource of TTI in a variety of TTI in selection window.It is illustrated for selecting the resource of a certain kind TTI in the resource of a variety of TTI by terminal device below.
Specifically, it is assumed that the resource of resource and long transmission time span (long TTI) in the sets of transmission resources including short transmission time span (short TTI).The terminal device obtain can by selecting the type of transmission time length to select above-mentioned at least one resource, for example, the terminal device select short TTI resource or long TTI resource as at least one above-mentioned resource.
More specifically, terminal device can first obtain the information of the corresponding channel quality of resource of the information and long TTI of the corresponding channel quality of resource of short TTI；Then, according to the information of the corresponding channel quality of resource of the information and long TTI of the corresponding channel quality of resource of short TTI, the resource of TTI a kind of is selected in the selection window.It is appreciated that a kind of information of the corresponding channel quality of the resource of TTI can be an information (for example, a threshold value) in the embodiment of the present invention；That is, the quality of the resource of corresponding TTI can be embodied by this information.
For example, it is assumed that the resource of short TTI corresponds to first threshold, the resource of long TTI corresponds to second threshold, and terminal device can select the resource of TTI a kind of by comparing the first threshold and the second threshold.
It should be understood that terminal device can carry out resource selection in physical layer in the embodiment of the present invention, resource selection can also be carried out in media access control layer, can also carry out resource selection in physical layer and media access control layer, the embodiment of the present invention is not specifically limited.
Based on (New Radio NR) technology of newly eating dishes without rice or wine, it polymerize (Carrier Aggregation in carrier wave, CA) under scene, the embodiment of the present invention, propose a kind of method for transmitting data, it can use the replicate data function of Packet Data Convergence Protocol (Packet Data Convergence Protocol, PDCP) layer, carry out data duplication (data duplication) transmission.The method of the data transmission of the embodiment of the present invention can effectively improve the reliability of data transmission.
Transmission method of the Fig. 4 to the replicate data under CA scene in the embodiment of the present invention is simply introduced below.
Fig. 4 is the schematic flow chart of the transmission method of the data of the PDCP layer of the embodiment of the present invention.
As shown in Figure 4, the data (replicate data of PDU and PDU) of PDCP layers of generation are respectively transmitted to two different RLC entity (RLC entity a and RLC entity b), the two different RLC entities are mapped to different physical-layer carriers (first carrier and the second carrier wave) by identical media intervention control (Media Access Control, MAC) layer entity (MAC entity).It is understood that, in embodiments of the present invention, PDCP layers of data (replicate data of PDU and PDU) generated are mapped in different physical-layer carriers by two different RLC entities respectively, can achieve the purpose that frequency diversity gain, and then can be improved the reliability of data transmission.
Specifically, each sublayer can be sent to the designated layer of receiving end according to the difference of the data of protocol Data Unit.Wherein, the data not processed into each sublayer are known as service data unit (service data unit, SDU), the data for specific format being formed after sub-layer processes are referred to as protocol Data Unit (Protocol Data Unit, PDU).That is, SDU is the information unit for being transmitted to lower layer protocol from upper-layer protocol, that is, the former data of SDU are the PDU on agreement upper layer.In other words, the PDU that this layer is formed is next layer of SDU.
For example, each logic channel of each terminal device has a RLC entity (RLC entity), the data that RLC entity is received from PDCP layers, or it is sent to PDCP layers of data and is properly termed as RLC SDU (or PDCP PDU).The data that RLC entity is received from MAC layer, or be sent to the data of MAC layer and be properly termed as RLC PDU (or MAC SDU).
It should be understood that rlc layer is located at PDCP layers between MAC layer, and rlc layer can be communicated by Service Access Point (Service Access Point, SAP) with PDCP layers, and be communicated by logic channel with MAC layer in the embodiment of the present invention.But the embodiment of the present invention is without being limited thereto.
In the embodiment of the present invention, when PDCP layers of data duplication is in activated state, the replicate data of PDCP layers of PDU (i.e. PDCP PDU) and PDCP PDU can be mapped in different physical-layer carriers by different RLC entities, can effectively improve the reliability of data transmission.
It can be found that although terminal device can effectively improve the reliability of data transmission when carrying out data duplication (data duplication) transmission in the replicate data function using PDCP layers.But, since 3GPP Rel-14 only considers the scene of single carrier, if the method that terminal device is transmitted using the data of the embodiment of the present invention, when i.e. the data copy function of the PDCP layer of terminal device is in activation, each sidelink progress can carry different RLC entities, that is, the scheduling of resource of terminal device needs
Consider the scene of multicarrier.Specifically, terminal device needs to consider the RLC entity of each carriers carry in multiple carrier waves.More specifically, terminal device needs to consider the RLC entity of each sidelink process carrying in carrier wave.
Such as, when terminal device uses scheduling of resource mode as described in Figure 2, when the data copy function of PDCP layer above is in activation, which needs to consider that Logic Channel Identifier (Logical Channel Identifier, LCID) arrives the mapping relations of sidelink process.
Therefore, when the data copy function that the embodiment of the present invention further provides a kind of PDCP layer of terminal device is in activation, terminal device is in the method for listening to resource pool.
Optionally, the data copy function of the PDCP layer of the terminal device is active, the PDCP layers corresponding at least one radio link control RLC entity, at least one above-mentioned RLC entity corresponds at least one physical-layer carrier, first carrier at least one above-mentioned physical-layer carrier includes at least one sidelink process, the first sidelink process at least one above-mentioned sidelink process carries first instance, at least one above-mentioned RLC entity includes the first instance；The RLC entity that the first sidelink process carries is switched to second instance by the first instance by the terminal device, at least one above-mentioned RLC entity includes the second instance.
Specifically, if the RLC entity that the first sidelink process carries can be switched to the second instance by the first instance by terminal device when terminal device currently wishes to switch the RLC entity of sidelink process carrying on first carrier.
For example, that the RLC entity of the first sidelink process carrying by the first instance is directly switched to the second instance is direct for terminal device.
In another example the RLC entity that the first sidelink process carries is switched to the second instance by the first instance by terminal device after the first sidelink process meets some requirements.
Fig. 5 is the exemplary block diagram of the scene of the method for listening to of the embodiment of the present invention.
Below by taking scene shown in fig. 5 as an example, the method for listening to of the embodiment of the present invention is introduced.
Specifically, as shown in Figure 5, assuming that the second sidelink process in the first sidelink process of terminal device and at least one above-mentioned sidelink process is used on the carrying first instance, if the terminal device currently wishes that the RLC entity for carrying the first sidelink process and/or the second sidelink process is switched on the second instance by the first instance.It should be understood that being only illustrated by taking the first sidelink process and the second sidelink process as an example in the embodiment of the present invention.But the embodiment of the present invention is not limited to this.
It is appreciated that if user currently wishes that the RLC entity that the first sidelink process carries is switched to the second instance by the first instance by terminal device, terminal device needs switch over processing under the scene of the embodiment of the present invention.
After the RLC entity by the first sidelink process carrying that terminal device receives user's triggering is switched to the request (for example, passing through user's operation) of the second instance by the first instance；The terminal device is switched to the request of the second instance in response to the RLC entity that carries the first sidelink process by the first instance, and the RLC entity which carries is switched to the second instance by the first instance.
Optionally, the RLC entity which carries directly can be switched to the second instance by the first instance by terminal device.But, in the embodiment of the present invention, if terminal device is switched to the request of the second instance in response to the RLC entity that carries the first sidelink process by the first instance, the RLC entity that the first sidelink process carries directly is switched into the second instance by the first instance, the frequency for very likely increasing resource gravity treatment, reduces data transmission efficiency.
Specifically, assuming that the data volume that the first sidelink process can carry is m, and the data volume of data to be transmitted is n on the logic channel where second instance, if n is greater than m, when the RLC entity that the first sidelink process carries directly is switched to the second instance by the first instance by terminal device, it is found that the first sidelink starvation of processe is to carry above-mentioned data to be transmitted, at this moment, it will lead to terminal device and re-start resource gravity treatment.
The frequency that resource gravity treatment is carried out to reduce terminal device further in the embodiment of the present invention, additionally provides a kind of method for listening to.Specifically, at the time of terminal device obtains the meeting of resource gravity concentrator according to the first sidelink process, the RLC entity which carries is switched into the second instance by the first instance.
Optionally, which switches to the second instance by the first instance for the RLC entity that the first sidelink process carries in resource gravity treatment.
Specifically, the terminal device is switched to the RLC entity that the first sidelink process carries before second instance by first instance, determined for the first moment, first moment is the first sidelink process at the time of obtaining the meeting of resource gravity concentrator after requesting the moment, at the time of which is that the terminal device receives the request；Then, which switches to the second instance by the first instance for the RLC entity that the first sidelink process carries at first moment.
It should be noted that the first carrier is corresponding at least one sidelink process, this at least one sidelink process is mutually indepedent in the embodiment of the present invention.Specifically, at least one above-mentioned skidding chain
Each sidelink process in the process of road has respective resource reselection timer (reselection timer), i.e. Cresel.
That is, each sidelink process at least one above-mentioned sidelink process can switch the RLC entity respectively carried at the time of obtaining the meeting of resource gravity concentrator after requesting the moment in the embodiment of the present invention.
It is thereby possible to cause certain sidelink processes at least one above-mentioned sidelink process on synchronization, different RLC entities is carried.
Further, to solve the above-mentioned problems, in the embodiment of the present invention, additionally provide a kind of method for listening to, at the time of obtaining the meeting of resource gravity concentrator by sidelink process each in multiple sidelink processes, determine when that the RLC entity for carrying the first sidelink process switches to the second instance by the first instance.

Further, the terminal device is in resource gravity treatment, if multiple sidelink processes at least one above-mentioned sidelink in addition to the first sidelink process carry the first instance, the first sidelink process is prevented to carry the first instance and the second instance；When each sidelink process in multiple sidelink process does not carry the first instance, allow the first sidelink process carrying should
Second instance.
Specifically, assuming that at the time of the request moment is that the terminal device receives the request, first moment is the first sidelink process at the time of obtaining the meeting of resource gravity concentrator after requesting the moment, which is the second sidelink process at the time of obtaining the meeting of resource gravity concentrator after the request moment；If first moment is before second moment, the terminal device determines the third moment, the third moment is the first sidelink process at the time of obtaining the meeting of resource gravity concentrator after second moment, and first sidelink is carried on and forbids carrying the first instance between first moment and second moment.
More specifically, if first moment is before second moment, the terminal device can be after the first sidelink process be at the time of obtaining the meeting of resource gravity concentrator after second moment, the RLC entity that the first sidelink process carries is switched into the second instance by the first instance, and first sidelink is carried on and forbids carrying the first instance between first moment and second moment.As a result, during switching the RLC entity of line link process carrying, it can be avoided the first sidelink process and the second sidelink process while carrying different RLC entities respectively.
In addition, being directed to the second sidelink process, which can switch to the second instance by the first instance for the RLC entity that the second sidelink process carries at second moment.
Further, in the embodiment of the present invention, each sidelink process at least one above-mentioned sidelink process in addition to second sidelink, obtained after the request moment resource gravity concentrator can at the time of before second moment.Each sidelink process at least one above-mentioned sidelink process is during the RLC entity of switching carrier as a result, it can be ensured that at least one described sidelink process carries same RLC entity on synchronization.
As another embodiment, optionally, the terminal device is in resource gravity treatment, if the second sidelink process at least one above-mentioned sidelink does not carry the first instance, the RLC entity which carries is switched to the second instance by the first instance.
Further, the terminal device is in resource gravity treatment, if the sidelink process at least one above-mentioned sidelink in addition to the first sidelink process does not carry the first instance, the RLC entity which carries is switched into the second instance by the first instance.
Specifically, assuming that at the time of the request moment is that the terminal device receives the request, first moment is the first sidelink process at the time of obtaining the meeting of resource gravity concentrator after requesting the moment, which is the second sidelink process at the time of obtaining the meeting of resource gravity concentrator after the request moment；If second moment, before first moment, which is determined as the third moment for first moment.Specifically, if second moment before first moment, the terminal device can this first
The RLC entity that the first sidelink process carries is switched to the second instance by the first instance by the moment.
In addition, being directed to the second sidelink process, which after first moment, was determined as the 4th moment at the time of obtaining the meeting of resource gravity concentrator for the second sidelink process；The terminal device switches to the second instance by the first instance at the 4th moment, by the RLC entity that the second sidelink process carries, and second sidelink is carried on and forbids carrying the second instance between second moment and first moment.The first sidelink process and the second sidelink process can be avoided the first sidelink process and the second sidelink process carry different RLC entities respectively during the RLC entity of switching carrier as a result,.
