Abstract

The present disclosure relates to an electronic device, a wireless communication method, and a computer-readable medium. The electronic device for wireless communication according to one embodiment comprises a processing circuit. The processing circuit is configured to obtain a set of collaborative devices of a target device, the set of collaborative devices comprising one or more collaborative devices. The processing circuit is further configured to control to send data for the target device to the target device and at least one collaborative device so that the at least one collaborative device forwards the data to the target device.

First claim

The invention claimed is:

1. An electronic device for wireless communication, comprising processing circuitry configured to:
receive from a wireless access point:
header information via a first channel, the header information containing information that identifies a target equipment that is to receive data from the wireless access point;
the data via a second channel different from the first channel,

wherein the first channel comprises a first set of time-frequency resources, and the second channel comprises a second set of time-frequency resources that does not overlap with the first set of time-frequency resources,
wherein a location of the header information in the first set of time-frequency resources corresponds to a location of the data in the second set of time-frequency resources,
wherein the first and second channels partially overlap in time and do not overlap in frequency, and
wherein a start time of the second channel occurs after a start time of the first channel and an end time of the second channel occurs after an end time of the first channel;
based on the header information, determine whether or not the electronic device is the target equipment that is to receive the data;
based on the header information indicating that the electronic device is the target equipment that is to receive data; process the data and send one of a first acknowledgement (ACK) or non-acknowledgement (NACK) to the wireless access point;
after receiving the data from the wireless access point, receive a copy of the data from at least one collaborative equipment,
wherein the copy of the data is received without a request from the electronic device; and
jointly process the data and the copy of the data and, based on a cyclic redundancy code (CRC) check, send one of a second acknowledgement (ACK) or non-acknowledgement (NACK) to the wireless access point.

2. The electronic device according to claim 1 , wherein the processing circuitry is configured to: perform control to transmit an Ultra-Reliable Low Latency Communication URLLC request for the data to the wireless access point.

3. The electronic device according to claim 1 , wherein the processing circuitry is further configured to:
determine a collaborative equipment set, the collaborative equipment set comprising one or more collaborative equipment; and
perform control to inform the wireless access point of the determined collaborative equipment set.

4. The electronic device according to claim 1 , wherein the processing circuitry is configured to perform control to transmit each of the following information to the wireless access point:
a nearby-equipment list of the current equipment;
position information of the current equipment;
quality of communication of the current equipment with the wireless access point; and
quality of communication of the current equipment with other equipment.

5. The electronic device according to claim 1 , wherein
a length of an OFDM symbol of the first channel is less than a length of an OFDM symbol of the second channel.

6. A method of wireless communication performed by an electronic device, the method comprising:
receiving from a wireless access point:
header information via a first channel, the header information containing information that identifies a target equipment that is to receive data from the wireless access point;
the data via a second channel different from the first channel,

wherein the first channel comprises a first set of time-frequency resources, and the second channel comprises a second set of time-frequency resources that does not overlap with the first set of time-frequency resources,
wherein a location of the header information in the first set of time-frequency resources corresponds to a location of the data in the second set of time-frequency resources,
wherein the first and second channels partially overlap in time and do not overlap in frequency, and
wherein a start time of the second channel occurs after a start time of the first channel, and an end time of the second channel occurs after an end time of the first channel;
based on the header information, determining whether or not the electronic device is the target equipment that is to receive the data;
based on the header information indicating that the electronic device is the target equipment that is to receive data; processing the data and sending one of a first acknowledgement (ACK) or non-acknowledgement (NACK) to the wireless access point;
after receiving the data from the wireless access point, receiving a copy of the data from at least one collaborative equipment,
wherein the copy of the data is received without a request from the electronic device; and
jointly processing the data and the copy of the data and, based on a cyclic redundancy code (CRC) check, sending one of a second acknowledgement (ACK) or non-acknowledgement (NACK) to the wireless access point.

7. A non-transitory computer product containing instructions for a method of wireless communication performed by an electronic device, the method comprising:
receiving from a wireless access point:
header information via a first channel, the header information containing information that identifies a target equipment that is to receive data from the wireless access point;
the data via a second channel different from the first channel,

wherein the first channel comprises a first set of time-frequency resources, and the second channel comprises a second set of time-frequency resources that does not overlap with the first set of time-frequency resources,
wherein a location of the header information in the first set of time-frequency resources corresponds to a location of the data in the second set of time-frequency resources,
wherein the first and second channels partially overlap in time and do not overlap in frequency, and
wherein a start time of the second channel occurs after a start time of the first channel, and an end time of the second channel occurs after an end time of the first channel;
based on the header information, determining whether or not the electronic device is the target equipment that is to receive the data;
based on the header information indicating that the electronic device is the target equipment that is to receive data; processing the data and sending one of a first acknowledgement (ACK) or non-acknowledgement (NACK) to the wireless access point;
after receiving the data from the wireless access point, receiving a copy of the data from at least one collaborative equipment,
wherein the copy of the data is received without a request from the electronic device; and
jointly processing the data and the copy of the data and, based on a cyclic redundancy code (CRC) check, sending one of a second acknowledgement (ACK) or non-acknowledgement (NACK) to the wireless access point.
