Resource allocation method, network device, and communications device

A network device, comprising:

• a processor and a transceiver;
• wherein the transceiver is configured to receive a quality of service (QoS) attribute information, wherein the QoS attribute information is used to indicate a QoS attribute of a first terminal device;
• and
• the processor is configured to allocate a transmission resource to the first terminal device according to the QoS attribute, wherein the transmission resource is used by the first terminal device to send data to a second terminal device;
• and
• wherein the QoS attribute information comprises a target index, and wherein the target index corresponds to the QoS attribute of the first terminal device, and the target index is used to indicate the QoS attribute of the first terminal device according to a correspondence between different QoS attributes and different indexes,
• wherein the transceiver is further configured to:
• before receiving unit receives the QoS attribute information sent by the first terminal device or the core-network network element, send a preset value to the first terminal device or the core-network network element,
• wherein the QoS attribute information is used to indicate a magnitude relationship between the data transmission rate and/or the reliability requirement of the first terminal device and the preset value, and
• wherein the magnitude relationship is one of following relationships:
• the data transmission rate and/or the reliability requirement of the first terminal device is greater than the preset value, the data transmission rate and/or the reliability requirement of the first terminal device is less than the preset value, the data transmission rate and/or the reliability requirement of the first terminal device is greater than or equal to the preset value, and the data transmission rate and/or the reliability requirement of the first terminal device is less than or equal to the preset value;
• or
• before the receiving unit receives the QoS attribute information sent by the first terminal device or the core-network network element, send a preset value to the first terminal device or the core-network network element,
• wherein the QoS attribute information is used to indicate a magnitude relationship between a data transmission rate and/or a reliability requirement of a target service and the preset value,
• wherein the magnitude relationship is one of the following relationships:
• the data transmission rate and/or the reliability requirement of the target service is greater than the preset value, the data transmission rate and/or the reliability requirement of the target service is less than the preset value, the data transmission rate and/or the reliability requirement of the target service is greater than or equal to the preset value, and the data transmission rate and/or the reliability requirement of the target service is less than or equal to the preset value, and
• wherein the target service is a service transmitted between the first terminal device and the second terminal device by using the transmission resource.

A communications device, comprising:

• a processor and a transceiver;
• wherein the processor is configured to determine a quality of service (QoS) attribute information, wherein the QoS attribute information is used to indicate a QoS attribute of a first terminal device;
• and
• the transceiver is configured to send the QoS attribute information to a network device, wherein the QoS attribute information is used by the network device to allocate a transmission resource to the first terminal device, and the transmission resource is used by the first terminal device to send data to a second terminal device,
• wherein the QoS attribute information comprises a target index, and wherein the target index corresponds to the QoS attribute of the first terminal device, and the target index is used to indicate the QoS attribute of the first terminal device according to a correspondence between different QoS attributes and different indexes,
• wherein the transceiver is further configured to:
• before the sending unit sends the QoS attribute information to the network device, receive a preset value sent by the network device,
• wherein the QoS attribute information is used to indicate a magnitude relationship between at least one of the data transmission rate or the reliability requirement of the first terminal device and the preset value, and
• wherein the magnitude relationship is one of the following relationships:
• at least one of the data transmission rate or the reliability requirement of the first terminal device is greater than the preset value, at least one of the data transmission rate or the reliability requirement of the first terminal device is less than the preset value, at least one of the data transmission rate or the reliability requirement of the first terminal device is greater than or equal to the preset value, and at least one of the data transmission rate or the reliability requirement of the first terminal device is less than or equal to the preset value;
• or
• before the sending unit sends the QoS attribute information to the network device, receive a preset value sent by the network device,
• wherein the QoS attribute information is used to indicate a magnitude relationship between at least one of a data transmission rate or a reliability requirement of a target service and the preset value,
• wherein the magnitude relationship is one of the following relationships:
• at least one of the data transmission rate or the reliability requirement of the target service is greater than the preset value, at least one of the data transmission rate or the reliability requirement of the target service is less than the preset value, at least one of the data transmission rate or the reliability requirement of the target service is greater than or equal to the preset value, and at least one of the data transmission rate or the reliability requirement of the target service is less than or equal to the preset value, and
• wherein the target service is a service transmitted between the first terminal device and the second terminal device by using the transmission resource.
