Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to the field of repeated transmission technology. Background Art

[0002] The NR (New Radio) system introduces two services: URLLC (Ultra-reliable low latency communication) and eMBB (Enhanced mobile broadband). The characteristic of URLLC is to achieve ultra-high reliability (for example, 99.999%) transmission within extreme latency (for example, 1ms), and the characteristic of eMBB is that it is insensitive to latency, but the number of transmissions can be large. For the scenario where URLLC and eMBB coexist, in order to achieve URLLC instant transmission, URLLC and eMBB will conflict, that is, URLLC occupies the resources already 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 reduce this effect, but it will cause the transmission delay of URLLC to increase. For the problem of uplink URLLC and eMBB transmission conflict, the method of stopping transmission can be used to reduce interference.

[0003] Similarly, URLLC services are also supported on NR-U (NR unlicensed spectrum) carriers. Unlicensed spectrum is a spectrum that can be used for radio equipment communications divided by countries and regions. This spectrum is generally considered to be a shared spectrum, that is, communication equipment in different communication systems can use the spectrum as long as they meet the regulatory requirements set by the country or region on the spectrum, without applying for exclusive spectrum authorization from the government.

[0004] However, on the NR-U carrier, when a conflict occurs between URLLC and eMBB transmissions and the transmission is stopped to reduce interference, if the URLLC transmission is repeated, only the repeated transmission with the conflict is interrupted, and there is no clear regulation on how to handle the remaining repeated transmissions. Summary of the invention

The wireless communication system 100 includes: a first communication device 110 and a second communication device 120, and signals are transmitted between the first communication device 110 and the second communication device 120.

[0035] The following implementation of the present application will elaborate on how to handle repeated transmission of URLLC when a transmission conflict occurs between URLLC and eMBB under the NR-U carrier.

[0036] Implementation Method 1

[0037] Please see Figure 2A , is an information transmission method provided in the first embodiment of the present application, the method comprising:

[0038] S210, if there is a conflicting resource in the first transmission resource of the first repeated transmission in the repeated transmission, interrupt the transmission of the first repeated transmission; wherein the number of repeated transmissions in the implementation manner of the present application may be one or more times, and the multiple times include two or more times; the first transmission resource is a resource configured for transmitting the first repeated transmission;

[0039] S220, processing signal transmission according to preset rules.

[0040] Optionally, the repeated transmission includes ultra-reliable low-latency communication URLLC repeated transmission on a new wireless unlicensed spectrum NR-U carrier.

[0041] Optionally, S220, processing signal transmission according to a preset rule includes:

[0042] A second repetition transmission in the repetition transmission whose transmission time is later than the first repetition transmission is abandoned.

[0043] The second repeated transmission refers to: all repeated transmissions after the first repeated transmission in the repeated transmission. For example, if the repeated transmission includes repeated transmission Rep#1, repeated transmission Rep#2, repeated transmission Rep#3 and repeated transmission Rep#4, if there are conflicting resources in the transmission resources of repeated transmission Rep#1, repeated transmission Rep#1 is the first repeated transmission, and repeated transmission Rep#2, repeated transmission Rep#3 and repeated transmission Rep#4 are the second repeated transmission.

[0044] Please see Figure 3, taking PUSCH (Physical Uplink Shared Channel) with 4 repeated transmissions Rep#1, Rep#2, Rep#3, and Rep#4 as an example for explanation.

[0045] Example 310, if there are conflicting resources in the transmission resources of repeated transmission Rep#1, that is, there is an overlap with the resources called by other transmissions, then starting from the starting position of the conflicting resource Overlap to the end of all repetitions, no transmission will be made, that is, Rep#2, Rep#3, and Rep#4 will not be transmitted.

[0046] Example 320, if the transmission resources of repeated transmission Rep#2 have resource conflicts, that is, there is an overlap with the resources called by other transmissions, then starting from the starting position of the conflicting resources to the end of all repetitions, no transmission will be performed, that is, Rep#3 and Rep#4 will not be transmitted.

[0047] In Example 330, if there is a resource conflict between the transmission resources of repeat Rep#1 and repeat Rep#2, that is, there is an overlap with the resources called by other transmissions, then starting from the starting position of the conflicting resources to the end of all repetitions, no transmission will be performed, that is, Rep#3 and Rep#4 will not be transmitted.

[0048] Directly stopping the transmission of all remaining repetitions can reduce the complexity of user terminal implementation, reduce interference when URLLC and eMBB transmission resources conflict, and ensure the reliability of URLLC. Figure 3 The filled part of the grid indicates that the signal is interrupted and the transmission stops, while the blank part indicates the signal transmission. Figures 4 to 7 The same is true in , and will not be repeated.

[0049] This embodiment 1 takes uplink signal transmission as an example to illustrate the technical solution of the present application. However, as mentioned above, the technical solution of the present application is not limited to uplink transmission, but can also be applied to downlink transmission and sidelink transmission.

[0050] Optionally, S220, processing signal transmission according to a preset rule includes:

[0051] S221, monitoring resources subsequent to the first transmission resource;

[0052] S222: Execute an operation corresponding to the interception result.

[0053] Optionally, S222, executing an operation corresponding to the interception result of the interception includes:

[0054] If the monitoring result is that the second transmission resource is available, the second repeated transmission is transmitted on the second transmission resource, and the time domain position of the second transmission resource is the same as the resource used to transmit the second repeated transmission before the first repeated transmission is interrupted.

[0055] The second transmission resource has the same time range as the resource used to transmit the second repeated transmission before the first repeated transmission is interrupted, and the frequency domain range may be the same or different. The same situation can be understood as: the second transmission resource is the resource configured to the user equipment for transmitting the second repeated transmission before the repeated transmission starts.

[0056] Please see Figure 4 Similarly, the example of PUSCH having 4 repeated transmissions Rep#1, Rep#2, Rep#3, and Rep#4 is used for illustration.

[0057] Example 410, if there are conflicting resources in the transmission resources of repeated transmission Rep#1, that is, there is an overlap with the resources called by other transmissions, that is, repeated transmission Rep#1 is the first repeated transmission, and repeated transmissions Rep#2, Rep#3, and Rep#4 are the second repeated transmissions. Before time point 411, listen to the transmission resources after the transmission resources where repeated transmission Rep#1 is located. If there are resources to transmit the second repeated transmission Rep#2, Rep#3, and Rep#4, they are the second transmission resources, and the second repeated transmission Rep#2, Rep#3, and Rep#4 are transmitted on the second transmission resources. Optional, otherwise, no transmission. Among them, the second transmission resources have the same time domain position as the resources used to transmit repeated transmissions Rep#2, Rep#3, and Rep#4 before the repeated transmission Rep#1 is interrupted, that is, they are resources adjacent to the resources of the interrupted transmission.

[0058] In example 420, if there are conflicting resources in the transmission resources of repeated transmission Rep#2, that is, there is an overlap with the resources called by other transmissions, before time point 421, listen to the resources adjacent to the repeated transmission resources where the conflicting resources are located, that is, the resources behind the time adjacent to Rep#2, if there are resources to transmit the second repeated transmission Rep#3, Rep#4, then transmit the second repeated transmission Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0059] In example 430, if there are conflicting resources in the transmission resources of repeated transmission Rep#1 and repeated transmission Rep#2, that is, there is an overlap with the resources called by other transmissions, before time point 431, listen to the resources adjacent to the repeated transmission resources where the conflicting resources are located, that is, the resources behind the repeated transmission Rep#2, if there are resources to transmit the second repeated transmission Rep#3 and repeated transmission Rep#4, then transmit the second repeated transmission Rep#3 and Rep#4. Optional, otherwise, do not transmit.

[0060] Optionally, S222, the performing an operation corresponding to the interception result of the interception includes:

[0061] If the monitoring result is that there are sufficient resources for transmitting the repeated transmission in the resources after the first transmission resources, the repeated transmission is transmitted on the sufficient resources for transmitting the repeated transmission.

[0062] The repeated transmission includes all repeated transmissions. For example, if there are 5 repeated transmissions Rep#1, Rep#2, Rep#3, Rep#4, and Rep#5 in PUSCH, the repeated transmission includes Rep#1, Rep#2, Rep#3, Rep#4, and Rep#5.

[0063] The resource following the first transmission resource may be a resource adjacent to the first transmission resource or a non-adjacent resource.

[0064] Please see Figure 5 Similarly, the example of PUSCH having 4 repeated transmissions Rep#1, Rep#2, Rep#3, and Rep#4 is used for explanation.

[0065] Example 510, if there are conflicting resources in the transmission resources of repeated transmission Rep#1, that is, there is an overlap with the resources called by other transmissions, before time point 511, listen to the resources adjacent to the repeated transmission resources where the conflicting resources are located, that is, the resources behind the time adjacent to Rep#1, if there are resources to transmit all repeated transmissions Rep#1, Rep#2, Rep#3, Rep#4, then transmit all repeated transmissions Rep#1, Rep#2, Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0066] Example 520, if there are conflicting resources in the transmission resources of repeated transmission Rep#2, that is, there is an overlap with the resources called by other transmissions, before time point 521, listen to the resources adjacent to the repeated transmission resources where the conflicting resources are located, that is, the resources behind the time adjacent to Rep#2, if there are resources to transmit all repeated transmissions Rep#1, Rep#2, Rep#3, Rep#4, then transmit all repeated transmissions Rep#1, Rep#2, Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0067] Example 530, if there are conflicting resources in the transmission resources of repetition Rep#1 and repetition Rep#2, that is, there is an overlap with the resources called by other transmissions, before time point 531, listen to the resources adjacent to the repetition transmission resources where the conflicting resources are located, that is, the resources behind adjacent to Rep#2, if there are resources to transmit all repetition transmissions Rep#1, Rep#2, Rep#3, Rep#4, then transmit all repetition transmissions Rep#1, Rep#2, Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0068] Please see Figure 6 Similarly, let's take the example of 4 repeated transmissions Rep#1, Rep#2, Rep#3, and Rep#4 in PUSCH for explanation.

[0069] Example 610, if there are conflicting resources in the transmission resources of Rep#1, that is, there is an overlap with the resources called by other transmissions, within time T, continue to listen to the resources after the repeated transmission resource time where the conflicting resources are located, if there are resources to transmit all repeated Rep#1, Rep#2, Rep#3, Rep#4, then transmit all repeated Rep#1, Rep#2, Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0070] Example 620, if there are conflicting resources in the transmission resources of Rep#2, that is, there is an overlap with the resources called by other transmissions, within time T, continue to listen to the resources after the repeated transmission resource time where the conflicting resources are located, if there are resources to transmit all repeated Rep#1, Rep#2, Rep#3, Rep#4, then transmit all repeated Rep#1, Rep#2, Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0071] Example 630, if there are conflicting resources in the transmission resources of Rep#1 and Rep#2, that is, there is an overlap with the resources called by other transmissions, within time T, continue to listen to the resources after the repeated transmission resource time where the conflicting resources are located, if there are resources to transmit all repeated Rep#1, Rep#2, Rep#3, Rep#4, then transmit all repeated Rep#1, Rep#2, Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0072] Optionally, S222, executing an operation corresponding to the interception result of the interception includes:

[0073] If the monitoring result is that there are sufficient resources for transmitting the second repeated transmission in the resources after the first transmission resources, the second repeated transmission is transmitted on the resources sufficient for transmitting the second repeated transmission.

[0074] Please see Figure 7 Similarly, the example of PUSCH having four repeated transmissions Rep#1, Rep#2, Rep#3, and Rep#4 is used for explanation.

[0075] Example 710, if there are conflicting resources in the transmission resources of repeated transmission Rep#1, that is, there is an overlap with the resources called by other transmissions, within time T, continue to listen to the resources after the repeated transmission resource time where the conflicting resources are located, if there are resources to transmit the remaining repetitions Rep#2, Rep#3, Rep#4, then transmit the remaining repetitions Rep#2, Rep#3, Rep#4. Optional, otherwise, do not transmit.

[0076] Example 720, if there are conflicting resources in the transmission resources of repeated transmission Rep#2, that is, there is an overlap with the resources called by other transmissions, within time T, continue to listen to the resources after the repeated transmission resource time where the conflicting resources are located, if there are resources to transmit the remaining repetitions Rep#3 and Rep#4, then transmit the remaining repetitions Rep#3 and Rep#4. Optional, otherwise, do not transmit.

[0077] Example 730, if there are conflicting resources in the transmission resources of repeat Rep#1 and repeat Rep#2, that is, there is an overlap with the resources called by other transmissions, within time T, continue to listen to the resources after the repeated transmission resource time where the conflicting resources are located, and if there are resources to transmit the remaining repeats Rep#3 and Rep#4, then transmit the remaining repeats Rep#3 and Rep#4. Optional, otherwise, do not transmit.

[0078] Optionally, S221, monitoring resources subsequent to the first transmission resource, includes:

[0079] The resource following the first transmission resource is continuously monitored until an available transmission resource is found.

[0080] Optionally, S221, monitoring resources subsequent to the first transmission resource, includes:

[0081] Continuously monitor resources after the first transmission resource, and if no available transmission resource is detected when the continuous monitoring time reaches the first time, stop monitoring; or,

[0082] The resource after the first transmission resource is continuously monitored, and if available transmission resources are detected when the duration of continuous monitoring is less than the first duration, the monitoring is stopped.

[0083] The user equipment starts to monitor from the resource adjacent to the transmission resource of the first repeated transmission.

[0084] Please see again Figure 6 and Figure 7 For example, in example 610, the time T between the time point 611 when the listening starts (i.e., the time when the conflicting resource ends) and the time point 612 when the listening ends. The time T may be in two situations:

[0085] Scenario 1: Listening starts at time 611, and then keeps listening to see if there are available resources until it is found that there are available resources at time 612, then stops listening and transmits data;

[0086] In the second scenario, T is limited, for example, T is limited to not exceed T1, that is, the listening starts at time point 611 when the conflicting resources end, and the listening stops at time point 612 until the duration of time T reaches a preset time period. If available resources are detected before T1, data transmission is performed. The limitation of time T can be agreed upon by the protocol or configured by the network.

[0087] above Figure 6 and Figure 7 The implementation methods of time T are the same as this and will not be repeated.

[0088] Implementation method 1 of the present application provides a processing rule for how to handle subsequent signal transmission when a resource conflict occurs during repeated transmission and the transmission is interrupted, thereby improving the system and enhancing the reliability of signal transmission.
