Background technique

NR (New Radio) system introduces URLLC (Ultra-reliable low latency communication, ultra-reliable, low-latency communication) and eMBB (Enhanced mobile broadband, enhanced mobile broadband) two services, URLLC characteristics are extreme To achieve ultra-high reliability (for example, 99.999%) transmission within the time delay (for example, 1 ms), eMBB is characterized by insensitive to delay, but the number of transmissions can be large. For the scenario where URLLC and eMBB coexist, in order to realize URLLC instant transmission, URLLC and eMBB will conflict, that is, URLLC occupies resources that have been allocated to eMBB. When URLLC and eMBB transmission conflict, URLLC and eMBB will interfere with each other, thereby affecting the demodulation performance of URLLC and eMBB. Retransmission can affect this, but it will cause the transmission delay of URLLC to increase. For the transmission conflict between the upstream URLLC and eMBB, the transmission can be stopped to reduce interference.

Similarly, URLLC services are also supported on the NR-U (NR unlicensed spectrum) carrier. The unlicensed spectrum is a spectrum that can be used for radio equipment communications divided by countries and regions. This spectrum is usually considered to be a shared spectrum. That is, the communication equipment in different communication systems can meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply for a proprietary spectrum authorization from the government.

However, on the NR-U carrier, when URLLC and eMBB transmission conflicts occur, and the transmission is stopped to reduce interference, if the URLLC transmission is repeated transmission, only the conflicting repeated transmission will be interrupted, and the remaining repeated transmissions There is no clear regulation on how to deal with it.

The apparatus according to claim 13, wherein the execution module is specifically configured to transmit the second repeated transmission on the second transmission resource if the interception indicates that the second transmission resource is available, The second transmission resource is the same as the time domain location of the resource used to transmit the second repeated transmission before the first repeated transmission is interrupted. .
The apparatus according to claim 13, wherein the execution module is specifically configured to: if the interception is that there are sufficient resources for transmitting the repeated transmission in the resources after the first transmission resource, Then the repeated transmission is transmitted on the resources sufficient for transmitting the repeated transmission.
The apparatus according to claim 14, wherein the execution module is specifically configured to: if the listening result is that there is sufficient resources for transmitting the second repeated transmission in the resources after the first transmission resource The second repeated transmission is transmitted on the resources sufficient for transmitting the second repeated transmission.
The apparatus according to any one of claims 10 to 16, wherein the listening module is specifically configured to continuously monitor resources after the first transmission resource, and stop until an available transmission resource is found .
The apparatus according to any one of claims 10 to 16, wherein the listening module is specifically configured to continuously listen to the resources after the first transmission resource, and if the duration of the continuous listening reaches the first transmission resource If the available transmission resource is not heard for a long time, stop listening; or continue to listen to the resources after the first transmission resource, if the duration of the continuous listening is less than the first duration When the available transmission resources are reached, stop listening.
A signal transmission device, wherein the device comprises: a processor, a memory, and a network interface; the processor calls a program in the memory to execute the signal transmission according to any one of claims 1 to 9 Method, and send the execution result through the network interface.
A chip, characterized by comprising: a processor, configured to call and run a computer program from a memory, and a device installed with the chip executes the signal transmission method according to any one of claims 1 to 9.
A computer-readable storage medium, wherein a program for the uplink transmission method is stored on the computer-readable storage medium, and the program for the uplink transmission method is executed by a processor to realize the above claims 1 to 9 The signal transmission method described in any one of.
A computer program product, wherein the computer program product is stored in a non-transitory computer-readable storage medium, and when the computer program is executed, the signal transmission method according to any one of claims 1 to 9 is realized .
