Description

Method, device and system for resource scheduling

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, device, and system for resource scheduling. Background technique

The purpose of the Internet of Things is to connect all items to the Internet through information sensing devices for intelligent identification and management. They can be combined with the Internet to realize remote sensing and control of all items and create a more intelligent production and living system. .

In the existing resource scheduling mechanism, after the user equipment is powered on, the user equipment first monitors the synchronization signal from the frequency band, reads the physical broadcast channel, obtains information such as bandwidth or entity indication channel configuration, and then monitors the physical downlink control channel and performs physical downlink control. The channel schedules subsequent system broadcasts, data reception and transmission, and the like. However, in the existing scheduling mechanism, the physical downlink control channel is transmitted in all frequency bands, and the format is uncertain. Each subframe of the user equipment needs to perform physical downlink control channel blind detection in the whole frequency band, and each blind detection is up to 40 times. In addition, the system broadcast is also based on dynamic scheduling, which may occupy any wide frequency band transmission at any position, while the user equipment in the connected state needs to maintain the uplink synchronization relationship, and the network side needs to continuously send timing advances for it to adjust its Synchronization relationship.

In addition, in order to make the data transmission efficiency higher, the user equipment needs to send the audio reference signal to enable the network side to learn the uplink channel quality, and the user equipment also measures the downlink channel and feeds back the downlink channel feature values such as the channel quality indicator to The network side can adjust the modulation and coding format of the uplink and downlink data according to the real-time channel quality. There is also a hybrid automatic retransmission mechanism in the existing mechanism, which makes the transmission efficiency higher. In order to support hybrid automatic retransmission, the user equipment needs to perform hybrid automatic retransmission feedback for downlink transmission in its own physical uplink control channel, and also requires the user equipment to support multiple redundancy version puncturing and soft combining capability.

In summary, the resource scheduling method in the prior art has high complexity, is not suitable for networked terminal transmission, and has high terminal cost and high energy consumption due to the high complexity of the resource scheduling method in the prior art. Summary of the invention

The message is selected to continue to send uplink data or re-initiate random access on the resource of the uplink data channel according to the random access response message sent by the base station. Specifically, after receiving the uplink data sent by the terminal device, the base station may determine whether the uplink data is successfully received. If the uplink data is successfully received, the base station may send a random access response message to the terminal device to notify the terminal device to continue on the uplink data channel. The new data is uploaded on the resource. If the data is not successfully received, the terminal device is notified to re-upload the data on the resource of the uplink data channel. Alternatively, the resource of the uplink data channel is allocated to other terminal devices, and the terminal device is randomly connected.

If the scheduling information sent by the base station indicates that the other terminal device occupies the scheduling resource (that is, the other terminal device occupies the resource of the uplink data channel that uploads the uplink data on the terminal device), the resource occupying the uplink data channel is stopped. The resources of the uplink data channel are released. If the uplink data needs to be sent, the random access may be re-initiated to the base station to obtain the resources of the new uplink data channel, and the uplink data is sent on the resources of the new uplink data channel.
