Fig. 2 is a schematic flow chart diagram of a method 200 of information transfer according to an embodiment of the present application. The method may alternatively be applied to the system shown in fig. 1, but is not limited thereto. The method includes at least part of the following.

S210, the terminal device receives a downlink control channel for indicating release of a Semi-static Scheduling (SPS) downlink data channel.

And S220, the terminal equipment sends feedback information corresponding to the downlink control channel.

If the downlink control channel is transmitted earlier than the first downlink data channel, the feedback information corresponding to the downlink control channel is not transmitted later than the feedback information corresponding to the first downlink data channel; if the downlink control channel is later than the first downlink channel, the feedback information corresponding to the downlink control channel is not earlier than the feedback information corresponding to the first downlink channel.

In this way, in the downlink control channel and the first downlink data channel, the feedback information corresponding to the channel transmitted first may precede the feedback information corresponding to the channel transmitted later.

Specifically, the transmission position in the time domain may include a period of time from the transmission start time to the transmission end time. According to the downlink control channel and the transmission position of the feedback information thereof, and the downlink data channel and the transmission position of the feedback information thereof, the following configuration may be performed in the terminal device: the feedback information corresponding to the channel transmitted first is before the feedback information corresponding to the channel transmitted later, so that the transmission complexity of the terminal equipment is not increased, and the transmission efficiency of the system is improved.

Optionally, in an embodiment of the present application, the method further includes:

the terminal equipment receives a first downlink data channel;

and the terminal equipment sends feedback information corresponding to the first downlink data channel.

Optionally, in this embodiment of the present application, the downlink control channel for indicating the release of the SPS downlink data channel is a PDCCH for indicating the release of the SPS PDSCH. Specifically, the SPS PDSCH release may be indicated by control information in the PDCCH.

The SPS downlink data channel may also be referred to as a second downlink data channel, as opposed to the first downlink data channel. For example, the first downlink data channel is a first PDSCH, and the SPS PDSCH is a second PDSCH.

Optionally, in this embodiment of the present application, the downlink data channel is a physical downlink shared channel PDSCH.

Optionally, in this embodiment, the feedback information may include HARQ ACK or HARQ NACK.

For example, the terminal device receives a downlink control channel from the network device indicating the release of the SPS PDSCH. Then, the terminal device sends feedback information of the PDCCH to the network device. Further, the terminal device also receives the first PDSCH from the network device. Then, the terminal device sends feedback information corresponding to the first PDSCH to the network device. In the PDCCH and the first PDSCH, feedback information corresponding to a channel transmitted first precedes feedback information corresponding to a channel transmitted later.

Optionally, in this embodiment of the present application, if the transmission ending time of the downlink control channel is earlier than the transmission starting time of the first downlink data channel, the transmission ending time of the feedback information corresponding to the downlink control channel is no later than the transmission starting time of the feedback information corresponding to the first downlink data channel.

For example, the transmission end time of the PDCCH for instructing the SPS PDSCH release received by the terminal device from the network device is earlier than the transmission start time of the first PDSCH, and the feedback information transmission end time of the PDCCH fed back by the terminal device to the network device is not later than the transmission start time of the feedback information of the first PDSCH.

Optionally, in this embodiment of the application, if the transmission start time of the downlink control channel is later than the transmission end time of the first downlink channel, the transmission start time of the feedback information corresponding to the downlink control channel is not earlier than the transmission end time of the feedback information corresponding to the first downlink channel.

For example, the transmission start time of the PDCCH indicating the SPS PDSCH release received by the terminal device from the network device is later than the transmission end time of the first PDSCH, and the transmission start time of the feedback information of the PDCCH fed back by the terminal device to the network device is not earlier than the transmission end time of the feedback information of the first PDSCH.

Optionally, in this embodiment of the present application, a transmission start time of the downlink control channel is later than a transmission end time of the first downlink data channel, and a transmission time slot of the feedback information corresponding to the downlink control channel is not earlier than a transmission time slot of the feedback information corresponding to the first downlink data channel.

For example, the terminal device receives a PDCCH from the network device indicating the release of the SPS PDSCH at a transmission start time later than a transmission end time of the first PDSCH. And the transmission time slot of the feedback information of the PDCCH fed back to the network equipment by the terminal equipment is not earlier than the transmission time slot of the feedback information of the first PDSCH.

Optionally, in this embodiment of the present application, the transmission ending time of the downlink control channel is earlier than the transmission starting time of the first downlink data channel, and the transmission time slot of the feedback information corresponding to the downlink control channel is not later than the transmission time slot of the feedback information corresponding to the first downlink data channel.

For example, the terminal device receives, from the network device, a PDCCH indicating a release of the SPS PDSCH at an end of transmission time earlier than a start of transmission time of the first PDSCH. And the transmission time slot of the feedback information of the PDCCH fed back to the network equipment by the terminal equipment is not later than the transmission time slot of the feedback information of the first PDSCH.

The feedback information of the channel transmitted first can be transmitted before the transmission time slot of the feedback information of the channel transmitted later without increasing the transmission complexity of the terminal equipment, and the transmission efficiency of the system can be improved.

Optionally, in this embodiment of the present application, a transmission start time of the first downlink data channel is T1, a transmission end time of the first downlink data channel is T2, and a transmission time slot of the feedback information corresponding to the first downlink data channel is X1.

For example, the transmission start time when the terminal device receives the first PDSCH from the network device is T1, and the transmission end time is T2. And the transmission time slot of the feedback information of the first PDSCH fed back to the network equipment by the terminal equipment is X1. That is, the terminal device starts receiving the first PDSCH at time T1 and completes receiving the first PDSCH at time T2. And the terminal equipment feeds back the feedback information of the first PDSCH to the network equipment in the time slot X1. Time T1 is before time T2 and time slot X1 is after time T2.

Optionally, in this embodiment of the present application, the downlink control channel is transmitted before the T1, and the feedback information corresponding to the downlink control channel is transmitted before the T1. Wherein, the terminal device receives the downlink control channel before the T1; and the terminal equipment sends the feedback information corresponding to the downlink control channel before the T1.

For example, the terminal device receives a PDCCH indicating a release of the SPS PDSCH from the network device before the transmission start time T1 of the first PDSCH. Then, the terminal device transmits feedback information of the PDCCH to the network device before time T1. That is, the terminal device receives the PDCCH for instructing the SPS PDSCH release, and then sends feedback information of the PDCCH to the network device. Then, the terminal device starts receiving the first PDSCH at time T1.

Optionally, in this embodiment of the present application, the downlink control channel is transmitted before the T1; the feedback information corresponding to the downlink control channel is transmitted between the T2 and the X1, or the feedback information corresponding to the downlink control channel is transmitted at the X1. Specifically, the terminal device receives the downlink control channel before the T1. The terminal device may send feedback information corresponding to the downlink control channel between the T2 and the X1. The terminal device may also send feedback information corresponding to the downlink control channel at the X1.

For example, the terminal device receives a PDCCH indicating a release of the SPS PDSCH from the network device before the transmission start time T1 of the first PDSCH. Then, the terminal device transmits the feedback information of the PDCCH to the network device after the transmission end time T2 of the first PDSCH and before the transmission slot X1 of the feedback information of the first PDSCH. That is, the terminal device receives the PDCCH instructing the SPS PDSCH release from the network device, starts receiving the first PDSCH again at time T1, and completes receiving the first PDSCH at time T2. Next, after time T2, the terminal device transmits feedback information of the PDCCH to the network device. Then, the terminal device transmits feedback information of the first PDSCH to the network device in time slot X1.

Optionally, in this embodiment of the present application, the downlink control channel is transmitted between the T2 and the X1, and the feedback information corresponding to the downlink control channel is transmitted after the X1 or the X1. Wherein the terminal device receives the downlink control channel between the T2 and the X1. The terminal device may send feedback information corresponding to the downlink control channel after the X1. The terminal device may also send feedback information corresponding to the downlink control channel at the X1.

For example, the terminal device receives a PDCCH indicating a release of the SPS PDSCH from the network device after the transmission end time T2 of the first PDSCH and before the transmission slot X1 of the feedback information of the first PDSCH. And after the transmission time slot X1 of the feedback information of the first PDSCH, transmitting the feedback information of the PDCCH to the network equipment. That is, the terminal device starts receiving the first PDSCH from the network device at time T1, and completes receiving the first PDSCH at time T2. After time T2, the terminal device receives a PDCCH indicating a release of the SPS PDSCH from the network device. Then, the terminal device sends the feedback information of the first PDSCH to the network device in time slot X1. Then, after slot X1, the terminal device transmits feedback information of the PDCCH to the network device.

Optionally, in this embodiment of the present application, the downlink control channel is transmitted after the X1, and the feedback information corresponding to the downlink control channel is transmitted after the X1. Specifically, the terminal device receives the downlink control channel after the X1; and the terminal equipment sends the feedback information corresponding to the downlink control channel after the X1.

For example, the terminal device receives a PDCCH indicating a release of the SPS PDSCH from the network device after the transmission slot X1 of the feedback information of the first PDSCH, and then transmits the feedback information of the PDCCH to the network device. That is, the terminal device starts receiving the first PDSCH from the network device at time T1, and completes receiving the first PDSCH at time T2. Then, the terminal device starts to transmit the feedback information of the first PDSCH to the network device in time slot X1. Then, after the time slot X1, the terminal device receives a PDCCH indicating the release of the SPS PDSCH from the network device, and transmits feedback information of the PDCCH to the network device.

The above describes some allowed time relationships of the terminal, and the following describes some not allowed time relationships of the terminal.

Optionally, in this embodiment of the present application, the downlink control channel is transmitted before the T1, and the feedback information corresponding to the downlink control channel is not transmitted after the X1. Specifically, if the terminal device receives the downlink control channel before T1, the terminal device does not expect to send feedback information corresponding to the downlink control channel after X1.

For example, the terminal device receives a PDCCH indicating a release of the SPS PDSCH from the network device before the transmission start time T1 of the first PDSCH. Then, the terminal device does not transmit the feedback information of the PDCCH to the network device after the transmission slot X1 of the feedback information of the first PDSCH. That is, the terminal device receives the PDCCH instructing the SPS PDSCH release from the network device, starts receiving the first PDSCH again at time T1, and completes receiving the first PDSCH at time T2. Then, the terminal device transmits the feedback information of the first PDSCH to the network device in time slot X1. In this case, the terminal device does not expect to transmit the feedback information of the PDCCH to the network device after slot X1. That is, after the time slot X1, the terminal device does not transmit the feedback information of the PDCCH to the network device.

Optionally, in this embodiment of the present application, the downlink control channel is transmitted between the T2 and the X1, and the feedback information corresponding to the downlink control channel is not transmitted between the T2 and the X1. Specifically, the terminal device receives the downlink control channel between the T2 and the X1, and the terminal device does not expect to send feedback information corresponding to the downlink control channel between the T2 and the X1.

For example, the terminal device receives a release PDCCH indicating an SPS PDSCH from the network device after the transmission end time T2 of the first PDSCH and before the transmission slot X1 of the feedback information of the first PDSCH. The terminal device does not transmit the feedback information of the PDCCH to the network device after time T2 and before time slot X1. That is, the terminal device starts receiving the first PDSCH from the network device at time T1 first, and completes receiving the first PDSCH at time T2. Next, after time T2 and before time slot X1, the terminal device receives a PDCCH indicating the release of the SPS PDSCH from the network device. In this case, the terminal device does not expect to transmit the feedback information of the PDCCH to the network device after time T2 and before time slot X1. That is, after time T2 and before time slot X1, the terminal device does not transmit the feedback information of the PDCCH to the network device.

The information transmission method provided by the embodiment of the application can improve the transmission efficiency of the system without increasing the transmission complexity of the terminal equipment.

Application example 1:

in an application example, for the PDCCH indicating the SPS PDSCH release and its feedback information transmission, and the first PDSCH and its feedback information transmission, the time relationship therebetween may be set as follows.

And determining a PDCCH transmission position for indicating the SPS PDSCH release and the position of the feedback information thereof based on the first PDSCH transmission position and the feedback information transmission position thereof. The PDCCH indicating the SPS PDSCH release and its corresponding feedback information are not between a set of PDSCHs and their corresponding feedback information at the same time. Nor is a set of PDSCH and its corresponding feedback information simultaneously between the PDCCH indicating the SPS PDSCH release and its corresponding feedback information.

It is assumed that the terminal device receives the first PDSCH in time slot n, and the feedback position of the feedback information of the first PDSCH is in time slot n + k. The transmission start time of the first PDSCH is T1, and the transmission end time of the first PDSCH is T2. The time T1 and/or the time T2 may be within the time slot n.

Case six: the terminal device receives the PDCCH indicating the SPS PDSCH release before time T1, and transmits the position of the feedback information corresponding to the PDCCH after slot n + k, as shown in fig. 9.

If data or signaling received earlier occurs, feedback information feedback is performed later. The terminal device needs to feed back the data or signaling received later, and meanwhile, needs to save the feedback result of the data or signaling received earlier, which increases the complexity of implementation.

In another example, the UE receives the first PDSCH in time slot i, the feedback information corresponding to the first PDSCH is transmitted in time slot j, and the UE does not expect to receive a PDCCH for instructing release of the SPS PDSCH after the first PDSCH and the feedback information corresponding to the PDCCH precedes time slot j.

According to the embodiment of the application, the terminal equipment can perform corresponding HARQ feedback according to the sequence of the received PDSCH and the PDCCH for indicating the SPS PDSCH release, so that the increase of the transmission complexity of the terminal equipment can be avoided, and the transmission efficiency of the system is improved.
