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.
The method that the terminal device being described below in the embodiment of the present invention obtains transfer resource.
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.
I.e., terminal device can carry the information of reserved next transfer resource in the control information of this transmission, so that other terminal devices can judge whether this block resource is reserved and used by the terminal device by detecting the control information of the terminal device, achieve 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 be understood that the method that terminal device shown in Fig. 3 listens to resource pool is the exemplary description that terminal device obtains resource, the embodiment of the present invention is not specifically limited.For example, the network equipment may be terminal device allocation of transmission resources.
The method of the transmission data of the embodiment of the present invention is introduced below.
Fig. 4 is the schematic flow chart of the method for the transmission data of the embodiment of the present invention.
As shown in figure 4, this method comprises:
210, terminal device generates media intervention control (Media Access Control, MAC) protocol Data Unit (Protocol Data Unit, PDU), the MAC PDU include the radio link layer control protocol RLC PDU from n logic channel.
220, which determines first carrier according to the priority of the n logic channel in multiple carrier wave；Wherein, n > 0.
230, which transmits the MAC PDU on the first carrier.
In brief, terminal device selects first carrier to be transmitted according to the priority of data in multiple carrier waves that terminal device has.
It should be noted that the priority due to data is related to MAC PDU group packet rule.
Therefore, there are a preconditions for the method for the data transmission of the embodiment of the present invention, i.e. terminal device can be configured with m logic channel and multiple carrier waves, each logic channel in the m logic channel is configured with priority, each carrier wave in multiple carrier wave is associated with the priority of at least one logic channel in the m logic channel, m > 0.
The terminal device can effectively select the carrier wave for being used for transmission data according to the priority of the logic channel of data correlation when transmitting data in multiple carrier waves as a result,.
Specifically, terminal device generates MAC PDU, which includes radio link layer control protocol (Radio Link Control, RLC) PDU from n logic channel, the n logic channel belongs to the m logic channel, m > n > 0；According to the priority of the n logic channel, first carrier is determined in multiple carrier wave；The transmission media intervention control MAC PDU on the first carrier.
It will be appreciated by those skilled in the art that, 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, the PDU that this layer is formed is next layer of SDU.
For example, each logic channel of terminal device has a RLC entity (RLC entity), the data that RLC entity is received from MAC layer, or it is sent to the data of MAC layer and is properly termed as RLC PDU (or MAC SDU).
The implementation that first carrier is determined in the embodiment of the present invention is described below.
It should be noted that in the prior art, terminal device can generate MACPDU according to certain principle.For example, when the priority of RLC SDU includes X in MAC PDU, it is assumed that the priority of X is higher than Y, and Y's is higher than Z, and Y and Z are the priority for the logic channel that terminal device has, then MAC PDU also will include the RLC SDU that priority is Y and Z.
Therefore, in the embodiment of the present invention, terminal device can the principle based on data priority select first carrier in multiple carrier waves that terminal device has.In such manner, it is possible to keep the generating process of current MAC PDU constant, and then it can be improved the method for transmission data and the compatibility of the prior art and the scope of application of the embodiment of the present invention.
It illustrates below.
As one embodiment, at least there is a carrier wave in multiple carrier waves that terminal device has, the priority of the associated logic channel of the carrier wave includes the priority of the corresponding logic channel of each RLC SDU in MAC PDU.
Specifically, terminal device generates MAC PDU, which includes the RLC PDU from n logic channel, which belongs to the m logic channel, m > n > 0；According to the priority of the n logic channel, first carrier is determined in multiple carrier wave, the associated priority of the first carrier includes: the priority of the n logic channel.
In this case, each carrier wave can be according to following rule association logic channel in multiple carrier wave
Priority:
When the associated priority of the second carrier wave includes the priority of the first logic channel in multiple carrier wave, the associated priority of second carrier wave further includes in the m logic channel lower than the priority of the logic channel of the priority of first logic channel, second carrier wave is any carrier wave in multiple carrier wave, which is any logic channel in the m logic channel.
That is, once it is determined that the second carrier wave can be associated with priority X, then all priority lower than X, should all be associated with second carrier wave when determining the associated priority of the second carrier wave.
For example, it is assumed that terminal device has 8 logic channels, the corresponding priority of each logic channel.For example, it is assumed that the priority of logic channel 1 is 1, the priority of logic channel 2 is 2, and so on, the priority of logic channel 8 is 8.If terminal device has 3 carrier waves.For example, carrier wave 1, carrier wave 2 and carrier wave 3.
Then, which can be according to the priority of following form correlation logic channel:
The associated priority of carrier wave 1 includes: 1,2,3,4,5,6,7,8.
The associated priority of carrier wave 3 includes: 5,6,7,8.
The associated priority of carrier wave 4 includes: 7,8.
As another embodiment, at least there is a carrier wave in multiple carrier waves that terminal device has, the priority of the associated logic channel of the carrier wave includes the priority of at least one corresponding logic channel of RLC SDU in MAC PDU.Such as, in the priority of the corresponding multiple logic channels of multiple RLC SDU of MAC PDU, select the first priority, first carrier is determined in multiple carrier waves that terminal device has according to this first priority, which is the highest priority or lowest priority in the priority of the n logic channel.
Specifically, terminal device generates MAC PDU, which includes the RLC PDU from n logic channel, which belongs to the m logic channel, m > n > 0；Terminal device can determine the first priority first in the priority of the n logic channel；Then, terminal device determines the first carrier according to the associated priority of carrier wave each in the first priority and multiple carrier wave determined.
For example, the terminal device generates MAC PDU, which includes the RLC PDU from n logic channel, which belongs to the m logic channel, m > n > 0；According to the priority of the n logic channel, the first carrier is determined in multiple carrier wave, the associated priority of the first carrier includes: the first priority in the priority of the n logic channel.Optionally, each associated priority of carrier wave is non-overlapping in multiple carrier wave.
In other words, for each carrier wave, there is one group of associated priority.Specifically, the RLC PDU from Different Logic channel for including in a MAC PDU, each logic channel have an associated priority.The first priority in the priority of the ownership logic channel of the RLC PDU of this MAC PDU, when in the associated priority group of the carrier wave, this MAC PDU can be put on the carrier wave and be transmitted.
Since only first priority and the associated priority of first carrier being compared, the present embodiment does not influence the generating process of MAC PDU.
As an example it is assumed that terminal device has 8 logic channels, the corresponding priority of each logic channel.For example, it is assumed that the priority of logic channel 1 is 1, the priority of logic channel 2 is 2, and so on, the priority of logic channel 8 is 8.If terminal device has 3 carrier waves.For example, carrier wave 1, carrier wave 2 and carrier wave 3.
Then, which can be according to the priority of following form correlation logic channel:
The associated priority of carrier wave 1 includes: 1,2,3,4.
The associated priority of carrier wave 2 includes: 5,6.
The associated priority of carrier wave 3 includes: 7,8.
In another example the terminal device generates MAC PDU, which includes the RLC PDU from n logic channel, which belongs to the m logic channel, m > n > 0；According to the priority of the n logic channel, the first carrier is determined in multiple carrier wave, the first priority in the priority of the n logic channel is lower than the associated priority of the first carrier.Optionally, each carrier wave is only associated with a priority in multiple carrier wave.
In other words, for each carrier wave, there is one group of associated priority.The RLC PDU from Different Logic channel for including in one MAC PDU, each logic channel have an associated priority.When this MAC PDU RLC PDU ownership logic channel priority in the first priority, lower than the carrier wave associated priority when, this MAC PDU can be put on the carrier wave and be transmitted.
In another example the terminal device generates MAC PDU, which includes the RLC PDU from n logic channel, which belongs to the m logic channel, m > n > 0；According to the priority of the n logic channel, the first carrier is determined in multiple carrier wave, the first priority in the priority of the n logic channel is higher than the associated priority of the first carrier.Optionally, each carrier wave is only associated with a priority in multiple carrier wave.
As an example it is assumed that terminal device has 8 logic channels, the corresponding priority of each logic channel.For example, it is assumed that the priority of logic channel 1 is 1, the priority of logic channel 2 is 2, with
This analogizes, and the priority of logic channel 8 is 8.If terminal device has 3 carrier waves.For example, carrier wave 1, carrier wave 2 and carrier wave 3.
Then, which can be according to the priority of following form correlation logic channel:
The associated priority of carrier wave 1 includes: 1.
The associated priority of carrier wave 2 includes: 5.
The associated priority of carrier wave 3 includes: 7.
Since only first priority and the associated priority of first carrier being compared, the present embodiment is also without the generating process of influence MAC PDU.
It should be understood that, each number in the present embodiment is exemplary illustration, the original intention of the embodiment of the present invention is the implementation that first carrier is determined in order to illustrate the priority in multiple carrier waves according to data of implementation and terminal of carrier wave correlation logic channel priority.
For example, the first priority in the embodiment of the present invention can be any priority in the priority of the n logic channel.
In another example, terminal device in the embodiment of the present invention can also select k priority in the priority of the n logic channel, wherein, k < n, then each associated priority of carrier wave in the multiple carrier waves being had according to the k priority and terminal device, determines the first carrier in the embodiment of the present invention.
Specifically, the associated priority of the first carrier may include the k priority.
