Abstract

Embodiments of the present application provide a wireless communication method, a terminal device and a network device capable of implementing contention-based access while avoiding conflicts. The method includes: transmitting, by a terminal device, a sounding signal to a network device when there is uplink data to be transmitted, where the sounding signal is used for contending for a first pre-allocated resource; and transmitting, by the terminal device, the uplink data to be transmitted on the first pre-allocated resource, when receiving a first feedback signal sent by the network device in response to the sounding signal, where the first feedback signal is used for indicate that the terminal device has a successful contention for the first pre-allocated resource.

Claims26

Dependent claims

A wireless communication method, comprising:

transmitting, by a terminal device, a sounding signal to a network device when there is uplink data to be transmitted, wherein the sounding signal is used for contending for a first pre-allocated resource;
and
transmitting, by the terminal device, the uplink data to be transmitted on the first pre-allocated resource, when receiving a first feedback signal sent by the network device in response to the sounding signal, wherein the first feedback signal is used for indicating that the terminal device has a successful contention for the first pre-allocated resource;
transmitting the uplink data to be transmitted on an uplink grant resource when the terminal device receives a second feedback signal sent by the network device in response to the sounding signal, wherein the second feedback signal is used for indicating the uplink grant resource which is different from the first pre-allocated resource;
starting a timer after transmitting the sounding signal;
wherein the transmitting, by the terminal device, the uplink data to be transmitted on the first pre-allocated resource, when receiving a first feedback signal sent by the network device in response to the sounding signal comprises:
transmitting, by the terminal device, the uplink data to be transmitted on the first pre-allocated resource, when receiving the first feedback signal within a duration of the timer;
and
wherein the transmitting the uplink data to be transmitted on an uplink grant resource when the terminal device receives a second feedback signal sent by the network device in response to the sounding signal comprises:
transmitting, by the terminal device, the uplink data to be transmitted on the uplink grant resource, when receiving the second feedback signal within the duration of the timer.

7 more elements

A terminal device, comprising a processor, a memory storing instructions, and a transceiver, wherein:

the processor is configured to call the instructions stored in the memory to:
generate a sounding signal when there is uplink data to be transmitted, wherein the sounding signal is used for contending for a first pre-allocated resource;
and
the transceiver is configured to:
transmit the sounding signal;
and transmit the uplink data to be transmitted on the first pre-allocated resource when a first feedback signal, which is sent by the network device in response to the sounding signal, is received, wherein the first feedback signal is used for indicating that the terminal device has a successful contention for the first pre-allocated resource;
wherein the transceiver is further configured to:
transmit the uplink data to be transmitted on an uplink grant resource when a second feedback signal, which is sent by the network device in response to the sounding signal, is received, wherein the second feedback signal is used for indicating the uplink grant resource which is different from the first pre-allocated resource;
wherein the transceiver is configured to:
start a timer after transmitting the sounding signal;
transmit the uplink data to be transmitted on the first pre-allocated resource when the first feedback signal is received within a duration of the timer;
transmit the uplink data to be transmitted on the uplink grant resource when the second feedback signal is received within the duration of the timer.
