Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.
The embodiments of the present application may be applicable to any terminal device-to-terminal device communication framework.
For example, vehicle-to-vehicle (Vehicle to Vehicle, V2V), vehicle-to-other devices (Vehicle to Everything, V2X), terminal-to-terminal (D2D), and the like.
The terminal in the embodiments of the present application may be any device or apparatus configured with a physical layer and a media access control layer, and the terminal device may also be referred to as an access terminal. Such as a User Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device having wireless communication capabilities, a computing device or other linear processing device connected to a wireless modem, an in-vehicle device, a wearable device, or the like. The embodiment of the present application will be described by taking an in-vehicle terminal as an example, but is not limited thereto.
In some embodiments of the present application, embodiments of the present application may be applicable to transmission mode 3 and transmission mode 4 defined in the third generation partnership project (3rd Generation Partnership Project,3GPP) Rel-14.
Fig. 1 is a schematic diagram of mode 3 of the embodiment of the present application. Fig. 2 is a schematic diagram of mode 4 of the embodiment of the present application.
In transmission mode 3 shown in fig. 1, transmission resources of the in-vehicle terminals (in-vehicle terminals 121 and 122) are allocated by the base station 110, and the in-vehicle terminals transmit data on the side links according to the resources allocated by the base station 110. Specifically, the base station 110 may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal.
In the transmission mode 4 shown in fig. 2, the vehicle-mounted terminals (the vehicle-mounted terminal 131 and the vehicle-mounted terminal 132) adopt a transmission mode of interception (sensing) and reservation (reservation), and the vehicle-mounted terminal autonomously selects transmission resources on the resources of the side links to perform data transmission.
The following specifically describes the in-vehicle terminal 131 as an example.
The vehicle-mounted terminal 131 acquires an available transmission resource set in a resource pool in a interception mode, and the vehicle-mounted terminal 131 randomly selects one resource from the set to transmit data.
Because the service in the internet of vehicles system has a periodic characteristic, in the embodiment of the present application, the vehicle terminal 131 may also adopt a semi-static transmission manner. That is, the in-vehicle terminal 131 takes one transmission resource and then uses the resource continuously in a plurality of transmission periods, so as to reduce the probability of resource reselection and resource collision.
Further, the vehicle-mounted terminal 131 may carry the information of the reserved secondary transmission resource in the control information of the present transmission, so that other terminals (for example, the vehicle-mounted terminal 132) may determine whether the resource is reserved and used by the user by detecting the control information of the user, thereby achieving the purpose of reducing the resource conflict.
It should be understood that, in the above embodiment, the transmission mode 3 and the transmission mode 4 are transmission modes defined in the LTE V2X system, and in the NR-V2X system, the transmission mode 3 and the transmission mode 4 may be used, or a new transmission mode may be defined, which is not limited in this application.
In an NR-V2X system, there may be two types of side links for the vehicle terminal: in addition, if the vehicle-mounted terminal has uplink data transmission, data transmission on the NR SL and data transmission on the LTE SL at the same time, how to perform power distribution is a technical problem which needs to be solved in the field.
Fig. 3 shows a schematic flow chart of a method 200 of adjusting power, which method 200 may be performed by an in-vehicle terminal, according to an embodiment of the present application. For example, the in-vehicle terminal 121 or the in-vehicle terminal 122 shown in fig. 1. As another example, the in-vehicle terminal 131 or 132 shown in fig. 2. The method 200 includes some or all of the following:
s210, when uplink data, data on the first type side link and data on the second type side link overlap in time, and the total power required exceeds the maximum transmission power of the terminal device, the terminal device adjusts at least one of the transmission power of the uplink data, the transmission power of the data on the first type side link and the transmission power of the data on the second type side link.
For example, when at least two of the uplink data, the data on the first type side link, and the data on the second type side link overlap in time, and the total power required exceeds the maximum transmission power of the terminal device, the terminal device adjusts at least one of the transmission power of the uplink data, the transmission power of the data on the first type side link, and the transmission power of the data on the second type side link.
For another example, the uplink data, the data on the first type side link, and the data on the second type side link overlap each other in time, and the terminal device adjusts at least one of the transmission power of the uplink data, the transmission power of the data on the first type side link, and the transmission power of the data on the second type side link when the total power required exceeds the maximum transmission power of the terminal device.
In other words, in the embodiment of the present application, whether there is a temporal overlap between the uplink data, the data on the first type side link, and the data on the second type side link, or whether there is a temporal overlap between the uplink data, the data on the first type side link, and the data on the second type side link, the terminal device needs to comprehensively consider the transmission power of the uplink data, the transmission power of the data on the first type side link, and the transmission power of the data on the second type side link. Thereby, the reliability of data transmission can be ensured.
In this embodiment of the present application, the terminal device may reasonably allocate the transmission power of the terminal device by adjusting at least one of the transmission power of the uplink data, the transmission power of the data on the first type side uplink, and the transmission power of the data on the second type side uplink.
It should be understood that, in the embodiment of the present application, the uplink data may be uplink data in the LTE system, or uplink data in the NR system, or uplink data in both the LTE system and the NR system may be included.
It should be understood that the specific types of the first type of side links and the second type of side links are not limited in the embodiments of the present application. In an embodiment, the first type of side links may be side links under a first communication system, and the second type of side links may be side links under a second communication system. For example, the first type of side-links are NR SL and the second type of side-links are LTE SL.
The specific implementation manner of adjusting the transmitting power of the terminal device is described in detail below.
In some embodiments of the present application, the terminal device adjusts at least one of the transmission power of the uplink data, the transmission power of the data on the first type of side link, and the transmission power of the data on the second type of side link according to a preset rule until the required total power is less than or equal to the maximum transmission power.
In some embodiments of the present application, the terminal device adjusts the transmission power of the first data on the first type of side link and/or the second data on the second type of side link until the required total power is less than or equal to the maximum transmission power, where the transmission requirement of the parameter of the first data is lower than or higher than a first threshold value, and the priority of the second data is lower than a second threshold value.
Further, if the total power required by the terminal device after adjusting the transmission power of the first data and the second data to 0 is still greater than the maximum transmission power, the terminal device adjusts the transmission power of the uplink data until the total power required is less than or equal to the maximum transmission power.
Still further, if the total power required by the terminal device after adjusting the transmit power of the uplink data to 0 is still greater than the maximum transmit power, the terminal device adjusts the transmit power of the data on the first type side link except for the first data and/or the transmit power of the data on the second type side link except for the second data until the total power required is less than or equal to the maximum transmit power.
For example, taking the first type of side link as an NR SL, and taking the second type of side link as an LTE SL as an example, the terminal device first obtains a first threshold and a second threshold, and then compares the first threshold with the terminal device according to a transmission requirement of a parameter of data on the NR SL, and compares the second threshold with the first threshold according to a priority of the data on the LTE SL. Specifically, the terminal device preferentially adjusts the transmitting power of the data on the NR SL and the LTE SL, which are respectively lower than the first threshold and the second threshold, until the power of the service is 0. If the power of all the traffic to be transmitted below the threshold is adjusted to 0, the required power also exceeds the maximum transmission power, the transmission power of the uplink data is adjusted, and then the transmission power of the data above the first threshold and the second threshold is adjusted until the required power is lower than the maximum transmission power.
A specific implementation manner of adjusting the transmission power of the first data on the first type side link and/or the second data on the second type side link by the terminal device is described below as an example.
In some embodiments of the present application, the terminal device may adjust the transmission power of the first data and/or the second data in order from low to high based on the priority of the first data and the priority of the second data.
The priority of the first data may be a priority of a service to which the first data belongs, and the priority of the second data may be a priority of a service to which the second data belongs, and in an embodiment, the first data and the second data may include data of at least one service.
It should be understood that embodiments of the present application are not limited to a specific form of the priority. For example, the Priority may be a near field communication Packet Priority (PPPP), and in an embodiment, the PPPP may be divided into 8 groups at maximum, and the range of values is 0-7. Wherein, the smaller the PPPP value, the higher the priority of data packet transmission, and one data packet may correspond to 1 or more PPPPs. In one embodiment, when data in a data packet corresponds to a plurality of PPPPs, the lowest value (corresponding to the highest priority) in the PPPPs is taken as the priority of the data packet.
It should also be understood that the terminal device adjusting the transmission power of the first data and/or the second data based on the priority of the first data and the priority of the second data is only one example of the embodiments of the present application, and should not be construed as limiting the embodiments of the present application.
For example, in other alternative embodiments, the terminal device may preferentially adjust the transmission power of the first data or preferentially adjust the transmission power of the second data.
For another example, in other alternative embodiments, the terminal device may adjust the transmit power of the first data and the second data based on the latency requirements of the first data and the second data. For example, the terminal device may adjust the transmit power of the first data and/or the second data in order from low to high based on the delay requirement of the first data and the delay requirement of the second data.
For another example, in other alternative embodiments, the terminal device may adjust the transmit power of the first data and the second data based on the reliability requirements of the first data and the second data. For example, the terminal device may adjust the transmission power of the first data and/or the second data in order from low to high based on the reliability of the first data and the reliability of the second data.
Specific implementation manners of adjusting the transmission power of the data except the first data on the first type side link and/or the transmission power of the data except the second data on the second type side link by the terminal device are described in an exemplary manner.
In some embodiments of the present application, the terminal device adjusts, in order from low to high, a transmission power of data on the first type side link other than the first data and/or a transmission power of data on the second type side link other than the second data based on a priority of data on the first type side link other than the first data and a priority of data on the second type side link other than the second data.
The priority of the data on the first type side link except the first data may be the priority of the service to which the data on the first type side link except the first data belongs, the priority of the data on the second type side link except the second data may be the priority of the service to which the data on the second type side link except the second data belongs, and in an embodiment, the data on the first type side link except the first data and the data on the second type side link except the second data may include at least one service.
It should be understood that, the terminal device adjusts the transmission power of the data on the first type side link except the first data and the data on the second type side link except the second data based on the priority of the data on the first type side link except the first data and the data on the second type side link except the second data is only an example of the embodiment of the present application, and should not be construed as limiting the embodiment of the present application.
For example, in other alternative embodiments, the terminal device may preferentially adjust the transmission power of the data on the first type side link except for the first data or preferentially adjust the transmission power of the data on the second type side link except for the second data.
For another example, in other alternative embodiments, the terminal device may adjust the transmit power of the first data and the second data based on the latency requirements of the data on the first type side link other than the first data and the data on the second type side link other than the second data. For example, the terminal device may adjust the transmission power of the first data and/or the second data in order of low to high latency requirements.
For another example, in other alternative embodiments, the terminal device may adjust the transmit power of the data on the first type side link other than the first data and the data on the second type side link other than the second data based on the reliability requirements of the data on the first type side link other than the first data and the data on the second type side link other than the second data. For example, the terminal device may adjust the transmission power of the first data and/or the second data in order of low to high reliability requirements.
It should be understood that the priority of the service is not specifically limited in the embodiments of the present application. For example, when the service to which the data belongs is a video service, the priority of the data may be the lowest priority or the highest priority.
In some embodiments of the present application, the priority of the data is carried in the sidestream control information SCI. I.e. the terminal device can obtain the priority of the data through the SCI.
In an embodiment, the parameters of the first data in the embodiment of the present application include at least one of the following: the priority of the first data, the time delay of the first data and the reliability of the first data. In other words, the first threshold comprises at least one of: priority threshold, latency threshold, and reliability threshold.
It should be understood that, in the embodiment of the present application, when the parameter of the first data is priority and/or reliability, the transmission requirement of the parameter of the first data is lower than the first threshold; when the parameter of the first data is time delay, the transmission requirement of the parameter of the first data is higher than a first threshold. That is, the terminal device may take the first type side uplink as an NR SL as an example, and when determining the first data on the NR SL, the terminal device may determine, as the first data, data on the NR SL having a priority level less than or equal to a priority threshold, and/or determine, as the first data, data on the NR SL having a transmission requirement for a delay greater than or equal to a delay threshold, and/or determine, as the first data, data on the NR SL having a transmission requirement for reliability less than or equal to a reliability threshold.
It should be understood that the first threshold and the second threshold may be thresholds configured by a network, or may be thresholds determined by the terminal device and the network in a negotiation manner, or may even be thresholds determined by the terminal device and other terminals in a negotiation manner, or may be pre-configured thresholds, which are not specifically limited in this embodiment of the present application.
In some embodiments of the present application, the parameter of the first data is index information, the index information being used to determine at least one of: the priority of the first data, the time delay of the first data and the reliability of the first data. That is, the first threshold is an index value threshold.
For example, the index information of the first data may correspond to at least one of a time delay of the first data and a reliability of the first data.
The index information of the first data according to the embodiment of the present application is described below by way of example with reference to table 1 (a correspondence table between the index information of the first data and the priority of the first data, the time delay of the first data, and the reliability of the first data).
TABLE 1
| Index | Priority level | Time delay | Reliability of |
| 3 | 0 | 10ms | 99.99％ |
| 2 | 0 | 20ms | 99.9％ |
| 1 | 1 | 10ms | 99％ |
| 0 | 2 | 100ms | 90％ |
As shown in table 1, the first threshold may be an index value threshold. For example, assuming that the index value threshold is index 1, the first threshold may be at least one of priority 1, delay 10ms, and reliability 99% corresponding to index 1. That is, the terminal device determines the first data from the data on the first side link according to at least one of priority 1, delay 10ms, and reliability 99% corresponding to index 1.
It should be understood that, in the embodiment of the present application, the first threshold is an index value threshold, which is only an example of the embodiment of the present application, and should not be construed as limiting the embodiment of the present application. For example, the first threshold may include a plurality of parameters. As shown in table 1, assuming that the index value threshold is index 1, the first threshold may further include at least one of the following: priority threshold 1, latency threshold 10ms, and reliability threshold 99%.
It should also be understood that the various specific values shown in table 1 are merely one example of an embodiment of the present application and should not be construed as limiting the embodiment of the present application.
In some embodiments of the present application, before the terminal device adjusts the transmitting power of the terminal device, the terminal device may further obtain, by using a preconfigured or network configured manner, a correspondence between the index information of the first data and the priority of the first data, the time delay of the first data, and the reliability of the first data.
