Communication methods, base stations and access points

technical field

The present application relates to the field of communication, and more particularly, to a communication method, a base station, and an access point.

Background technique

With the continuous improvement of data transmission rate and communication quality requirements for mobile communications, the existing frequency bands for mobile communications have become very crowded. However, in the mmWave frequency band from 6GHz to 300GHz, there are still a large number of spectrum resources that have not been allocated. Introducing the millimeter wave frequency band into cellular access communications and making full use of the large bandwidth resources of the millimeter wave frequency band is one of the important research directions for the next generation of 5G mobile communication technology.

In the existing research, the high-frequency band represented by the millimeter-wave frequency band is mainly used in indoor short-distance communication scenarios. In outdoor scenarios, due to the complex terrain, high-frequency band loss, weak ability to penetrate obstacles, and severe rain attenuation at certain frequencies, the application of high-frequency bands in outdoor scenarios is severely restricted.

However, due to its short wavelength, the high-frequency band is easy to implement a large-scale array antenna, and can bring large directional antenna gain through beam-forming technology, thereby effectively compensating for its high path loss. The application of medium and long-distance transmission in the scene provides the possibility. However, if there are obstacles in high-frequency communication, the link may be interrupted, thereby limiting the service range of the base station.

Therefore, in order to make better use of high-frequency spectrum resources for communication, it is necessary to study new communication methods based on its characteristics, which can improve the service range of the base station and the ability of resource allocation and scheduling, thereby improving the resource utilization efficiency of the entire network and Transmission robustness of the entire communication system.

Optionally, the scheduling result may include time-frequency resources and destination information for data transmission by each node to be scheduled.

In the following, Table 1 is taken as an example to explain in detail what information the scheduling result may include.

Table 1

It can be seen from Table 1 that the set of APs to be scheduled includes AP1, AP2 and AP3, the set of terminal devices to be scheduled includes UE1, UE2, UE3, UE4 and UE5, the scheduling period is T, and in the first time slot of the scheduling period (slot), the length of the first time slot can be 0.4T, AP1 and AP2 send data to the base station, UE4 and UE5 send data to AP3, UE1, UE2 and UE3 are in an idle (IDLE) state; in the second time slot, The length of the second time slot can be 0.4T, AP1 sends data to the base station, AP3 and UE3 send data to AP2, UE3 sends data to AP2, UE1, UE2, UE4 and UE5 are in the IDLE state; in the third time slot, the The length of the third time slot may be 0.2T, AP2 sends data to the base station, UE1 and UE2 send data to AP1, UE4 and UE5 send data to AP3, and UE3 is in the IDLE state.

The above is only described by taking the scheduling result as an example to indicate the time domain resource allocated by the base station to each node to be scheduled, but it should not constitute any limitation to the embodiment of the present application. In the embodiment of the present application, the scheduling result can also indicate the For the frequency domain resource allocated by the base station to each node to be scheduled, the indication method of the frequency domain resource can refer to the indication method of the time domain resource shown in Table 1, and the embodiment of the present application does not limit the indication method of the time domain resource and the frequency domain resource .

Optionally, the node to be scheduled may use a millimeter wave network to transmit data.

For example, if the scheduling result is as shown in Table 1, and the node to be scheduled is UE2, it can be seen from Table 1 that the data transmission request of UE2 is a request to send data to AP1, and the UE2 can transmit data at the third node indicated by the scheduling result. Send data to AP1 when the time slot arrives. For another example, if the node to be scheduled is AP1, the data transmission request of AP1 includes two (the data transmission request destination is the base station, and the data reception request from UE1 and UE2), according to As a result of the scheduling, the AP1 can send data to the base station when the first time slot and the second time slot arrive, and receive data sent from UE1 and UE2 when the third time slot arrives.
