Detailed Description
Fig. 1 is a schematic diagram of a 5G application scenario according to an embodiment of the present invention.
As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air. Multi-service transport is supported between terminal device 110 and network device 120.
It should be understood that the embodiment of the present invention is only exemplified by the 5G communication system 100, but the embodiment of the present invention is not limited thereto. That is to say, the technical solution of the embodiment of the present invention can be applied to various scenarios including a 5G communication system. For example, a mixed deployment scenario composed of the 5G communication system and the first communication system, and the like. The first communication system may be any one of communication systems. For example: a Long Term Evolution (LTE) system, a Time Division Duplex (TDD) system, a Universal Mobile Telecommunications System (UMTS) system, and the like.
Furthermore, various embodiments are described herein in connection with a network device and a terminal device.
Network device 120 may refer to any entity on the network side that transmits or receives signals. E.g., base station equipment in a 5G network, etc.
Terminal device 110 may be any terminal device. Specifically, the terminal device 110 may communicate with one or more Core networks (Core networks) through a Radio Access Network (RAN), and may also be referred to as an Access terminal, a User Equipment (UE), a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. For example, it may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having Wireless communication capability, a computing device or other processing device connected to a Wireless modem, an in-vehicle device, a wearable device, etc.
In 5G, a Semi-Persistent Scheduling (SPS) timer is defined. Specifically, there are defined:
1. when a retransmission data/new transmission data is transmitted on semi-static resources/or dynamic resources scheduled based on semi-static Radio Network Temporary Identifier (RNTI), the timer is started;
2. when the timer is running, if the user has semi-static resources at the current time, the user does not make any transmission;
3. when the timer is running, the user receives the dynamic resource scheduled based on the semi-static RNTI, the timer is stopped or started, and the timer is restarted based on 1.
However, for the above scenario, since transmission is allowed on semi-static resources in a Long Term Evolution (LTE) system, the Long Term Evolution (Long Term Evolution) system conflicts with the 5G specification, and thus the compatibility with the existing system framework is poor.
Therefore, the embodiment of the invention provides a method for retransmitting data, which can effectively improve the compatibility of 5G and the existing system framework.
Fig. 2 is a schematic flow chart of a method of retransmitting data according to an embodiment of the present invention.
Specifically, as shown in fig. 2, the method includes:
the terminal device determines 210 that the first SPS resource is configured with availability at the current transmission time.
220, the terminal device determines whether to transmit retransmission data to the network device using the first SPS resource.
That is, when the terminal device is configured with the first SPS resource at the current transmission time, the terminal device needs to determine whether to transmit the retransmission data to the network device using the first SPS resource. It should be understood that, in the embodiment of the present application, the result determined by the terminal device may be to transmit retransmission data to the network device by using the first SPS resource, or may be to transmit retransmission data to the network device without using the first SPS resource. The embodiment of the present application does not limit the specific determination result.
In the embodiment of the application, the terminal device determines whether to transmit the retransmission data to the network device by using the first SPS resource of the terminal device, so that compatibility with an existing system framework can be improved, and user experience is further improved.
For ease of understanding, the following is an exemplary illustration of an implementation in which the terminal device determines to utilize the first SPS resource for data retransmission:
in one embodiment, the terminal device receives first configuration information sent by the network device, where the first configuration information is used to configure whether the terminal device sends the retransmission data to the network device by using the first SPS resource; thus, the terminal device determines whether to utilize the first SPS resource to send the retransmission data to the network device according to the first configuration information.
In other words, before the network device receives the retransmission data sent by the terminal device on the first SPS resource, the network device sends first configuration information to the terminal device, so that the terminal device determines whether to send the retransmission data to the network device by using the first SPS resource according to the first configuration information.
In another embodiment, the terminal device may determine whether to transmit the retransmission data to the network device using the first SPS resource according to a state of a timer or a counter used by the terminal device.
For example, assume that the terminal device uses an SPS timer.
Thus, the terminal device may determine to transmit the retransmission data to the network device using the first SPS resource when determining that the SPS timer is running.
Further, the terminal device may determine to transmit the retransmission data to the network device at the first SPS resource when transmitting the retransmission data to the network device using the first SPS resource; the terminal device continues to run the SPS timer.
It should be understood that, in the embodiment of the present application, the operation of the SPS timer is continued only for exemplary description, and the embodiment of the present application is not limited thereto, for example, the SPS timer may also be restarted.
Further, the terminal device may determine whether to transmit the retransmission data to the network device using the first SPS resource before the terminal device receives second configuration information transmitted by the network device, where the second configuration information is used to configure the duration of the SPS timer for the terminal device.
In other words, before the network device receives the retransmission data sent by the terminal device on the first SPS resource, the network device sends the second configuration information to the terminal device, so that the terminal device determines whether the SPS timer is overtime according to the duration of the SPS timer, and further determines whether to retransmit the data by using the first SPS resource. That is, the terminal device determines that the SPS timer is running and transmits the retransmission data to the network device using the first SPS resource.
Also for example, assume that the terminal device uses a transmission number counter.
Thus, the terminal device may determine to transmit the retransmission data to the network device using the first SPS resource when determining that the transmission number counter does not reach the maximum transmission number.
Further, when the terminal device determines to transmit the retransmission data to the network device by using the first SPS resource, the terminal device may transmit the retransmission data to the network device at the first SPS resource; the terminal device adds 1 to the counted number of the transmission number counter.
It should be understood that, in the embodiment of the present application, adding 1 to the statistical number of the transmission number counter is merely an exemplary description, and the embodiment of the present application is not limited thereto, for example, the statistical number of the transmission number counter may not be changed.
Further, before the terminal device determines whether to send the retransmission data to the network device by using the first SPS resource, the terminal device receives fourth configuration information sent by the network device, where the fourth configuration information is used to configure the maximum transmission times of the transmission times counter for the terminal device.
In other words, before the network device receives the retransmission data sent by the terminal device on the first SPS resource, the network device sends the fourth configuration information to the terminal device, so that the terminal device determines whether to retransmit the data by using the first SPS resource according to whether the transmission number counter exceeds the maximum transmission number. That is, the terminal device sends the retransmission data to the network device by using the first SPS resource when determining that the transmission number counter does not reach the maximum transmission number.
In another embodiment, the terminal device may further determine whether the terminal device uses the first SPS resource for data retransmission based on a preset condition.
For example, the terminal device may determine to transmit the retransmission data to the network device using the first SPS resource when determining that the periodicity of the first SPS resource is less than a first threshold.
Further, before the terminal device determines whether to transmit the retransmission data to the network device by using the first SPS resource, the terminal device may receive third configuration information transmitted by the network device, where the third configuration information is used to configure a periodicity of the first SPS resource of the terminal device. In other words, before the network device receives the retransmission data sent by the terminal device on the first SPS resource, the network device sends the third configuration information to the terminal device, so that when the terminal device determines that the period of the first SPS resource is less than the first threshold, the network device sends the retransmission data to the network device by using the first SPS resource.
It should be understood that, in the embodiment of the present application, the terminal device determines whether to utilize the first SPS resource for data retransmission based on the state of the timer or the counter, but the scope of the present application is not limited thereto.
For example, when the terminal device uses a counter, the terminal device may determine whether the terminal device uses the first SPS resource for data retransmission based on the state of the counter in combination with a preset condition. More specifically, assuming that the terminal device uses a counter, it may be determined to transmit the retransmission data to the network device using the first SPS resource when the counter does not exceed the maximum number of transmissions and the periodicity of the first SPS resource is less than a first threshold.
In addition, in this embodiment of the present application, if the terminal device determines whether to transmit retransmission data to the network device by using the first SPS resource based on the state of the timer or the counter. The terminal device also needs to determine whether to use the SPS timer and/or the transmission number counter before determining whether to transmit retransmission data to the network device using the first SPS resource.
Further, in the embodiment of the present application, a method for determining whether to use a timer or a counter by a terminal device is also provided.
Specifically, the terminal device may determine whether to use a timer or a counter according to the network configuration. For example, further, before the terminal device determines whether to use the SPS timer and/or the transmission number counter, the terminal device receives fifth configuration information sent by the network device, where the fifth configuration information is used to configure a Hybrid Automatic Repeat Request (HARQ) mode adopted by the terminal device. Therefore, the terminal device can determine whether to use the SPS timer and/or the transmission number counter according to the HARQ scheme adopted by the terminal device.
For example, when the terminal device determines to adopt the synchronous HARQ scheme, it may determine to use the transmission number counter. For another example, when the terminal device determines to adopt the synchronous HARQ scheme, it may determine not to use the SPS timer. For another example, when the terminal device determines to adopt the asynchronous hybrid automatic repeat request HARQ scheme, the terminal device may determine to use the SPS timer. For another example, when the terminal device determines to use the asynchronous hybrid automatic repeat request HARQ scheme, it may determine not to use the transmission number counter.
In other words, before the network device receives the retransmission data sent by the terminal device on the first SPS resource, the network device sends the fifth configuration information to the terminal device, so that the terminal device determines not to use the SPS timer or use the transmission number counter when determining to adopt the synchronous hybrid automatic repeat request HARQ scheme, or determines to use the SPS timer or not to use the transmission number counter when determining to adopt the asynchronous hybrid automatic repeat request HARQ scheme.
Finally, it is noted that the terminal device determines whether to send the retransmission data to the network device on the second SPS resource before sending the retransmission data to the network device using the first SPS resource, or sends the retransmission data to the network device on a resource scheduled by a Physical Downlink Control Channel (PDCCH) that is scrambled using an SPS radio network temporary identity.
Wherein the first SPS resource and the second SPS resource may be SPS resources scheduled by the same grant information. The first SPS resource and the second SPS resource may also be SPS resources scheduled for different grant information. The embodiments of the present application are not particularly limited.
