Description

Method and device for transmitting data

Technical Field

The embodiments of the present application relate to the field of communications, and more particularly, to a method and apparatus for transmitting data.

Background

The Vehicle networking system is a Sidelink (SL) transmission technology based on a Long Term evolution Vehicle to Vehicle (LTE D2D), and is different from a mode that communication data is received or sent by a base station in a traditional LTE system, and the Vehicle networking system adopts a mode of direct terminal-to-terminal communication, so that the Vehicle networking system has higher spectral efficiency and lower transmission delay.

The Vehicle networking technology, Vehicle to other device (V2X) technology, is standardized in the third Generation Partnership Project (3 GPP) Rel-14, defining two modes of transmission: mode 3 and mode 4. Specifically, in the mode 3, the transmission resource of the vehicle-mounted terminal is allocated by the base station, and the vehicle-mounted terminal transmits data on the side uplink according to the resource allocated by the base station; the base station may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal. In the mode 4, the vehicle-mounted terminal (adopting a transmission mode of listening plus reservation), specifically, the vehicle-mounted terminal acquires an available transmission resource set in a resource pool through a listening mode, and the terminal randomly selects a resource from the set to transmit data.

However, 3GPP Rel-14 only considers a single carrier scenario, and therefore, in a multi-carrier scenario, how to control the usage of each carrier, for example, whether the CA scheme or the non-CA scheme is adopted for transmission, is an urgent problem to be solved.

It should be understood that the Terminal device in the embodiment of the present application may also be referred to as a Terminal (Terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like. The terminal device may be a Vehicle User Equipment (VUE), for example, a wireless terminal in a vehicle or a self driving (self driving), or the like; alternatively, the terminal device may also be a pedestrian handheld terminal (PUE), such as a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, and the like.

It should be understood that the network device according to the embodiments of the present application is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different 5 radio access technologies, the names of devices with base station functionality may differ. For example, in an LTE network, referred to as an evolved node B (eNB or eNodeB), in a third Generation (3rd Generation, 3G) network, referred to as a node B (node B), and so on.

In this embodiment of the present application, the car networking system may also support Carrier Aggregation (CA) transmission, and specifically, a Packet Data Convergence Protocol (PDCP) entity may respectively submit duplicated PDCP Protocol Data Units (PDUs) to different Radio Link Control (RLC) entities, so as to finally ensure that the duplicated PDCP PDUs can be transmitted on different carriers, thereby obtaining a frequency diversity gain and further improving transmission reliability.

It can be understood that, in the embodiment of the present application, data (PDU and PDU copy data) generated by the PDCP layer is mapped to different physical layer carriers through two different RLC entities, so as to achieve the purpose of frequency diversity gain, and further improve the reliability of data transmission.

Therefore, how to control whether the data transmission between the carriers is performed by the CA method or the non-CA method is an urgent problem to be solved.

and S320, the first terminal equipment performs data transmission with the second terminal equipment according to the using mode of the first carrier.

It should be noted that, in this embodiment of the present application, each carrier of the first terminal device may correspond to corresponding configuration information, or may also correspond to corresponding configuration information for a part of carriers, and the configuration information corresponding to the carriers may be used to control under what conditions the carriers may be used, or under what conditions the carriers may not be used, that is, the configuration information of the carriers may be used to control a usage manner or a usage condition of the carriers, or the configuration information of the carriers may be used to indicate a usage condition of the carriers.

It should be understood that, in the embodiment of the present application, how to control the use condition of the first carrier of the first terminal device is described as an example, that is, how to control the first carrier to be used under what condition and not to be used under what condition, and no limitation should be made to the embodiment of the present application, and how to control the use condition of other carriers may refer to the description related to the embodiment of the present application and is not described herein again.

It should be noted that, in this embodiment of the present application, the performing, by the first terminal device, data transmission with the second terminal device according to the usage mode of the first carrier may include performing, by the first terminal device, data transmission with the second terminal device by using the first carrier, performing, by the first terminal device, data transmission without using the first carrier with the second terminal device, performing data transmission with the first terminal device by using the first carrier with the second terminal device in a certain mode, for example, a data copying mode or a data non-copying mode, and the like, which is not particularly limited in this embodiment of the present application.

Optionally, in this embodiment of the application, the configuration information is first configuration information pre-stored on the first terminal device, or second configuration information configured to the first terminal device by a network device. Wherein the second configuration information has a higher priority than the first configuration information.

That is, if the first terminal device pre-stores the first configuration information, the network device sends the second configuration information to the first terminal device, and the first terminal device preferentially controls the usage mode of the first carrier according to the second configuration information.

Optionally, in this embodiment of the present application, the first carrier corresponds to a first carrier set, and a carrier in the first carrier set is a carrier that cannot be used simultaneously with the first carrier under a specific condition. The information of the first carrier set may be included in the configuration information of the first carrier, or may also be independent configuration information, each carrier of the first terminal device may correspond to a corresponding carrier set, and the carrier sets corresponding to each carrier may be the same or different.

Optionally, the configuration information includes a first corresponding relationship between a first carrier set and a usage condition of the first carrier.

For example, the first corresponding relationship may be a corresponding relationship between usage conditions of the carriers in the first carrier set and usage conditions of the first carriers, and by way of example and not limitation, the first corresponding relationship may be that the first carriers can be used simultaneously when the carriers in the first carrier set are in a first condition, or the first carriers cannot be used simultaneously when the carriers in the first carrier set are in a second condition, and the like.

For example, the first carrier set may include Carr2, Carr3, and Carr4, and the first corresponding relationship may be that Carr1 (i.e., the first carrier) is not used at the same time in a case where any one of Carr2, Carr3, and Carr4 is used, or Carr1 is not used at the same time in a case where Carr2, Carr3, and Carr4 are all used.

Optionally, as still another embodiment, the determining, by the first terminal device, a usage manner of the first carrier according to usage of carriers in the first set of carriers and the first correspondence relationship, where the first correspondence relationship is used to indicate that when at least one bearer of a specific priority of the first terminal device is using any carrier in the first set of carriers, the determining by the first terminal device of the first carrier usage manner includes:

Similar to the above embodiment, except that the at least one bearer is at least one bearer with a specific priority, the priority of the at least one bearer may be determined according to the packet priority of the packet to be transmitted, specifically, the packet priority of the packet to be transmitted may be determined first, and then, which bearers with the priorities can transmit the packet priority of the packet may be determined, it should be understood that the specific priority may include one or more priorities.

In this embodiment, the first corresponding relationship is used to indicate that when the first terminal device is using any carrier in the first carrier set in the replicated data manner, the first terminal device cannot use the first carrier in the replicated data manner at the same time, that is, if any carrier in the first carrier set is transmitting replicated data, the first carrier is not transmitting replicated data at the same time. Optionally, the first terminal device may use the first carrier in a non-duplicate data manner, that is, the first terminal device may use the first carrier to transmit non-duplicate data, or as long as when the first carrier and the carrier in the first carrier set are used simultaneously, the usage manner of the first carrier and the carrier in the first carrier set is different, and here, the usage manner may refer to what manner is used, for example, whether the first carrier is used in a duplicate data manner or in a non-duplicate data manner.

Optionally, the first terminal device may use the first carrier in the duplicated data manner simultaneously when the carrier in the first carrier set uses the non-duplicated data manner for data transmission, that is, the first terminal device may use the first carrier to transmit duplicated data at this time, that is, the carrier in the first carrier set and the first carrier may correspond to different usage manners, where the usage manner may refer to what manner is used, for example, whether to use the duplicated data manner or the non-duplicated data manner.

For example, if the first terminal device determines that a second carrier of a first set of carriers is in use and the second carrier is transmitting voice traffic, the first terminal device may determine not to transmit voice traffic using the first carrier (i.e., not to transmit the same type of traffic using the carrier of the first set of carriers and the first carrier). Optionally, the first terminal device may use the first carrier to transmit other services besides voice services, for example, video services. Or, if the first terminal device determines that a second carrier in a first carrier set is in use and the second carrier is transmitting voice traffic, the first terminal device may determine to transmit other traffic except the voice traffic using the first carrier when the current CBR of the first carrier falls within a first CBR range and/or the current RSSI of the first carrier falls within a first RSSI range.

That is to say, in this embodiment of the present application, the first terminal device may determine the usage manner of the first carrier only according to the first corresponding relationship, or may determine the usage manner of the first carrier only according to the second corresponding relationship, or may determine the usage manner of the first carrier by combining the first corresponding relationship and the second corresponding relationship, which is not described herein again.
