Abstract

Embodiments of this disclosure provide an information transmission method and apparatus and a system. The method is applicable to a terminal, the terminal being configured with a first type of resource pool for transmitting first type of information and a second type of resource pool for transmitting second type of information; wherein, the method includes: when the terminal is triggered to transmit information, it selects resources for transmitting the information from the configured first type of resource pool or second type of resource pool according to an attribute of the information; and transmits the information by using the selected resources. With the embodiments of this disclosure, it may be ensured that the terminal will not miss detecting a type of information due to a semi-duplexing problem, such as detecting resources for transmitting emergency information, thereby increasing utilization of resources, and improving reliability of V2V communications.

Claims

1. An information transmission apparatus, applicable to a terminal, the terminal being configured with a first type of resource pool for transmitting first type of information and a second type of resource pool for transmitting second type of information, the apparatus comprising:

a memory configured to store a plurality of instructions;

processor circuitry coupled to the memory, wherein the processor circuitry is configured to;

select resources, when the terminal is triggered to transmit information, for transmitting the information from the configured first type of resource pool or second type of resource pool according to an attribute of the information; and

transmit the information by using the selected resources,

select the resources for transmitting the first type of information from the configured first type of resource pool, when the information is the first type of information, and select a predefined number of consecutive valid subframes from selectable subframe resources as the resources for transmitting the first type of information,

select the resources for transmitting the second type of information from the configured second type of resource pool, when the information is the second type of information,

wherein when resources in the first type of resource pool and resources in the second type of resource pool overlap, the resources selected by the processor circuitry from the configured second type of resource pool for transmitting the second type of information do not consecutively occupy in a time domain the predefined number of consecutive valid subframes in the first type of resource pool.

2. The apparatus according to claim 1, wherein the processor circuitry is configured to

receive a triggering command from an application layer, the triggering command triggering the terminal to transmit the information, and indicating whether the attribute of the information is the first type of information or the second type of information.

3. An information transmission method, applicable to a terminal, the terminal being configured with a first type of resource pool for transmitting first type of information and a second type of resource pool for transmitting second type of information, the method comprising:

selecting, when the terminal is triggered to transmit information, resources for transmitting the information from the configured first type of resource pool or second type of resource pool according to an attribute of the information; and

transmitting the information by using the selected resources,

wherein when the information is the first type of information, the step of selecting resources comprises;

selecting the resources for transmitting the first type of information from the configured first type of resource pool, and selecting a predefined number of consecutive valid subframes from selectable subframe resources as the resources for transmitting the first type of information,

wherein when the information is the second type of information, the step of selecting resources comprises;

selecting the resources for transmitting the second type of information from the configured second type of resource pool,

wherein when resources in the first type of resource pool and resources in the second type of resource pool overlap, the resources selected from the configured second type of resource pool for transmitting the second type of information do not consecutively occupy in a time domain the predefined number of consecutive valid subframes in the first type of resource pool.

4. The method according to claim 3, wherein when selecting the resources for transmitting the second type of information from the configured second type of resource pool, it is avoided to select resources from the second type of resource pool occupying in the time domain the predefined number of consecutive valid subframes in the first type of resource pool.

5. The method according to claim 3, wherein after the resources for transmitting the second type of information are selected from the configured second type of resource pool, when the selected resources occupy in the time domain the predefined number of consecutive valid subframes in the first type of resource pool, a part of the predefined number of consecutive valid subframes is abandoned.

6. The method according to claim 3, wherein the method further comprises:

receiving a triggering command from an application layer, the triggering command triggering the terminal to transmit the information, and indicating whether the attribute of the information is the first type of information or the second type of information.

7. The apparatus according to claim 6, wherein when the apparatus selects the resources for transmitting the second type of information from the configured second type of resource pool, it avoids selecting resources from the second type of resource pool occupying in the time domain the predefined number of consecutive valid subframes in the first type of resource pool.

8. The apparatus according to claim 6, wherein after the resources for transmitting the second type of information are selected from the configured second type of resource pool, when the selected resources occupy in the time domain the predefined number of consecutive valid subframes in the first type of resource pool, the processor circuitry abandons a part of the predefined number of consecutive valid subframes.

9. A communications system, comprising a transmitter end and a receiver end, wherein,

the transmitter end is configured with a first type of resource pool for transmitting first type of information and a second type of resource pool for transmitting second type of information, and when the transmitter end is triggered to transmit information, it selects resources from the configured first type of resource pool or second type of resource pool according to an attribute of the information, and transmits the information by using the selected resources,

wherein when the information is the first type of information, the transmitter end selects the resources for transmitting the first type of information from the configured first type of resource pool, and selects a predefined number of consecutive valid subframes from selectable subframe resources as the resources for transmitting the first type of information,

wherein, when the information is the second type of information, the transmitter end selects the resources for transmitting the second type of information from the configured second type of resource pool,

wherein when resources in the first type of resource pool and resources in the second type of resource pool overlap, the resources selected by the transmitter end from the configured second type of resource pool for transmitting the second type of information do not consecutively occupy in a time domain the predefined number of consecutive valid subframes in the first type of resource pool.

10. The communications system according to claim 9, wherein the receiver end is also configured with the first type of resource pool for transmitting first type of information and the second type of resource pool for transmitting second type of information, and when the receiver end is triggered to transmit information, it selects resources from the configured first type of resource pool or second type of resource pool according to an attribute of the information, and transmits the information by using the selected resources.

11. The communications system according to claim 9, wherein the system further comprises:

an eNB configured to configure the transmitter end and/or the receiver end with a first type of resource pool for transmitting first type of information and a second type of resource pool for transmitting second type of information.
