Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for allocating acknowledgement message frame resources for a terminal, a method and an apparatus for allocating acknowledgement message frame resources for a base station, and a communication device.
Background
Currently, development work of a 5 th generation mobile communication system (5G) is actively underway. According to future application requirements, the 5G system needs to support multiple service scenarios, wherein communication scenarios with Low Latency and high reliability (URLLC), such as unmanned driving and industrial automation, are receiving wide attention. Generally, URLLC data has very high burstiness and high requirement on delay, so that the data has very high resource scheduling priority. The solution proposed at present for downlink transmission of URLLC data is: when the URLLC data arrives, the 5G base station (gNB) immediately schedules the URLLC data, that is, performs puncturing transmission in an enhanced Mobile Broadband (eMBB) data block in which resource allocation has been completed, so as to realize the fastest data transfer and further meet the requirement of the URLLC data on time delay. Therefore, the downlink URLLC data can be transmitted well in the central scheduling mode.
In a network, there may be a UE (User Equipment, user terminal) that supports both an eMBB service and a URLLC service, and when there is URLLC data to be transmitted for these UEs, according to the existing technology, SR (Scheduling Request) transmission needs to be performed, and a gbb performs resource allocation, and then the UE performs acknowledgement when performing uplink URLLC data transmission and the gbb performs acknowledgement, and the complete process of data transmission should include an acknowledgement process, so that a receiver can know whether the data is completely received through message frame acknowledgement, but the standard does not specify resource allocation for acknowledgement message frames.

It should be noted that, the steps 402 and 404 are not limited in sequence, that is, the second type of service data sent by the terminal may be received after receiving the reception delay allowed by the acknowledgement message frame sent by the terminal; or the receiving time delay is transmitted together with the second type of service data; or the receiving time delay and the second type service data are received together.
Preferably, the time-frequency resource between receiving the second type of service data and sending the acknowledgement message frame is unoccupied.
In this embodiment, the time frequency resources from the position of the time frequency resource for receiving the second type of service data to the position of the time frequency resource for sending the acknowledgment message frame are unoccupied, that is, the time frequency resources are idle, so that smooth sending of the acknowledgment message frame can be ensured.
In an embodiment of the third aspect of the present invention, an apparatus for allocating an acknowledgment message frame resource is provided, where the apparatus is applied to a terminal, and the terminal supports a first type of service and a second type of service, and fig. 5 shows a schematic diagram of an apparatus 50 for allocating an acknowledgment message frame resource for a terminal according to an embodiment of the present invention. Wherein the device 50 comprises:
a sending module 502, configured to transmit the second type of service data to the base station by using the time-frequency resource allocated to the first type of service data by the base station;
a receiving module 504, configured to receive a confirmation message frame for the second type of service data by using an unoccupied time-frequency resource when the time-frequency resource is not occupied by all the second type of service data, where a reception delay of receiving the confirmation message frame meets a delay requirement of the second type of service.
The device 50 for allocating frame resources of acknowledgement messages according to the present invention supports a first type of service and a second type of service, specifically, the first type of service data is eMBB data, and the second type of service data is URLLC data. When a second type of service comes, if the time delay requirement of the second type of service data is met, the terminal transmits the second type of service data by using the time-frequency resource allocated to the first type of service data by the base station. When the second type of service data does not fully occupy the time frequency resource, the remaining time frequency resource can be used as the transmission resource of the confirmation message frame of the second type of service data. The resource allocation of the URLLC data is optimized, so that the terminal does not need to send the SR to obtain the resource allocated to the URLLC data by the base station, the time delay requirement of the URLLC data is greatly met, and meanwhile, the resource allocation of the confirmation message frame is designed, and the URLLC data can be confirmed in time. And the receiving time delay of the received confirmation message frame meets the time delay requirement (the time delay requirement is half a subframe, namely 0.5 ms) of the second type of service, so that the validity of the confirmation message frame is ensured, and the phenomenon that the URLLC data cannot be confirmed in time is avoided.
Further, in the above technical solution, after the UE sends the second service data, the gNB may have a time interval before replying the acknowledgment message of the second service data, and the gNB may not allocate the time interval to any UE for use, or may allocate to a UE of this type if the gNB knows that a certain UE has very small data to transmit and can complete within the time interval.
Furthermore, in the above technical solution, the UE may only support one service data, or may simultaneously support two service data, and the time period occupied by the UE for sending the second type of data may be the time period of the UE itself or another UE.
It should be noted that, if the second type of service data is an uplink data frame, the acknowledgment message frame is a downlink data frame, and the time-frequency resource is originally arranged to transmit uplink data.
In a specific embodiment, the terminal may be a network device such as a smart phone, a tablet computer, and a notebook computer. The sending module 502 may be a transmitter or an antenna, etc., and the receiving module 504 may be a receiver or an antenna, etc.
Preferably, the sending module 502 is further configured to transmit the reception delay allowed by the acknowledgement message frame to the base station.
In this embodiment, in consideration of the delay of URLLC data processing, the reception delay of the acknowledgment message frame that can be allowed by the terminal may be taken after the second-type service data is transmitted to the base station, so as to ensure that the base station can feed back the acknowledgment message frame to the terminal within the reception delay, thereby improving feedback efficiency.
Preferably, the time-frequency resource between the transmission of the second type of service data and the reception of the acknowledgement message frame is unoccupied.
In this embodiment, the time frequency resources from the location of the time frequency resource for transmitting the second type of service data to the location of the time frequency resource for receiving the acknowledgment message frame are unoccupied, i.e., the time frequency resources are idle, thereby ensuring smooth reception of the acknowledgment message frame
Preferably, the modulation and coding strategy and the transmission power of the second type of service data and the acknowledgement message frame are the same.
In this embodiment, the modulation and coding strategy and the transmission power of the acknowledgement message frame are consistent with those of the second type of service data, so as to ensure validity and correctness of the acknowledgement message frame reception. Such as: the MCS of the second type of service data is MCS4, and the transmission power is 10dbm, the MCS mode and the transmission power of the acknowledgement message frame are consistent with those of the second type of service data, so that the robustness of the acknowledgement message frame can be ensured to be the same as that of the second type of service data.
Fig. 6 is a schematic diagram illustrating an apparatus 60 for allocating an acknowledgment message frame resource for a base station according to an embodiment of the present invention. Wherein the device 60 comprises:
a receiving module 602, configured to receive the second type of service data sent by the terminal by using the time-frequency resource allocated to the first type of service data;
a sending module 604, configured to send a confirmation message frame for the second type of service data to the terminal by using the unoccupied time-frequency resources when the time-frequency resources are not occupied by all the second type of service data.
In the device 60 for allocating frame resources of acknowledgement messages provided by the present invention, the base station allocates time-frequency resources to the first type of service data of the terminal, and receives the second type of service data sent by the terminal on the time-frequency resources. When the time frequency resource is not occupied by the second service data (namely the second service data only occupies a part of the time frequency resource), the unoccupied time frequency resource is utilized to send the confirmation message frame for the second service data. The invention optimizes the resource allocation of the URLLC data, greatly meets the time delay requirement of the URLLC data, designs the resource allocation of the confirmation message frame, and is beneficial to timely confirmation of the URLLC data.
The terminal supports a first type of service and a second type of service, and specifically, the first type of service data is eMBB data, and the second type of service data is URLLC data. If the second type of service data is an uplink data frame, the acknowledgement message frame is a downlink data frame, and the time-frequency resource is originally arranged to transmit the uplink data.
Further, in the above technical solution, after the UE sends the second service data, the gNB may have a time interval before replying the acknowledgment message of the second service data, and the gNB may not allocate the time interval to any UE for use, or may allocate to a UE of this type if the gNB knows that a certain UE has very small data to transmit and can complete within the time interval.
Furthermore, in the above technical solution, the UE may only support one service data, or may simultaneously support two service data, and the time period occupied by the UE for sending the second type data may be a time period of its own or other UEs.
In a specific embodiment, the terminal may be a network device such as a smart phone, a tablet computer, and a notebook. The receiving module 602 may be a receiver or an antenna, etc., and the sending module 604 may be a transmitter or an antenna, etc.
Preferably, the receiving module 602 is further configured to receive a reception delay allowed by an acknowledgement message frame sent by the terminal.
In this embodiment, in consideration of the delay of URLLC data processing, the terminal may carry the reception delay of the acknowledgment message frame that the terminal can allow after transmitting the second type of service data to the base station, and ensure that the base station feeds back the acknowledgment message frame to the terminal within the reception delay.
Preferably, the sending module 604 is specifically configured to send, to the terminal, an acknowledgement message frame for the second type of service data within the reception delay; and the modulation coding strategy and the transmission power of the confirmation message frame and the second type of service data are the same.
In this embodiment, the base station feeds back the acknowledgement message frame to the terminal within the reception delay, so as to improve the feedback efficiency. And the modulation coding strategy and the transmission power of the confirmation message frame are consistent with those of the second type of service data so as to ensure the validity and the correctness of the confirmation message frame reception. Such as: the MCS of the second type of service data is MCS4, and the transmission power is 10dbm, the MCS mode and the transmission power of the acknowledgement message frame are consistent with those of the second type of service data, so that the robustness of the acknowledgement message frame can be ensured to be the same as that of the second type of service data.
Preferably, the time frequency resource between receiving the second type of service data and sending the acknowledgement message frame is unoccupied. In this embodiment, the time frequency resources from the position of the time frequency resource for receiving the second type of service data to the position of the time frequency resource for sending the acknowledgment message frame are unoccupied, that is, the time frequency resources are idle, so that smooth sending of the acknowledgment message frame can be ensured.
