AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned wireless communication system, when the UE needs to use multiple AI technologies to transmit services on one carrier, it can only be realized by the above-mentioned time-division method on the carrier, that is, some dedicated subframes can only be used by the UE. It is used when a certain AI technology is used, but cannot be used when the UE adopts other AI technologies, and these dedicated subframes are fixed once allocated, so the above-mentioned time division method will lead to low resource utilization, and resource utilization Utilization is not flexible

Embodiment 1

[0181] like figure 1 As shown, the embodiment of the present invention provides a resource allocation method, and the resource allocation method may include:

[0182] S101. The base station determines at least two first AI technologies to be used for service transmission between the UE and the base station.

[0183] In the embodiment of the present invention, when transmitting services between the UE and the base station (including sending data from the base station to the UE and sending data from the UE to the base station, the service / data includes signaling and user data), the first AI technology needs to be used. Wherein, the first AI technology is also called radio interface technology (English: radio interface technology, abbreviated: RIT) or radio interface protocol (English: radio interface protocol, abbreviated: RIP). The first AI technology may generally include multiple access (English: multiple access), modulation and coding scheme (English: modulation and coding ...

Embodiment 2

[0388] like Figure 20 As shown, the embodiment of the present invention provides a resource allocation method, and the resource allocation method may include:

[0389] S201. The base station determines at least two first AI technologies to be used for service transmission between the UE and the base station.

[0390] S202. The base station allocates at least two first resources corresponding to at least two first AI technologies on the first carrier.

[0391] Wherein, at least two first resources are used for transmitting services between the UE and the base station.

[0392] S203. The base station sends first resource allocation information to the UE, where the first resource allocation information is used to indicate a first resource corresponding to a first AI technology to be adopted by the UE that receives the first resource allocation information.

[0393] In this embodiment, the number of the foregoing UEs may be one or multiple. When the number of the above-mention...

Embodiment 3

[0401] like Figure 21 As shown, the embodiment of the present invention provides a resource allocation method, and the resource allocation method may include:

[0402] S301. The UE receives first resource allocation information sent by the base station.

[0403] Wherein, the first resource allocation information is used to indicate at least two first resources allocated by the base station on the first carrier, the at least two first resources are used for transmitting services between the UE and the base station, and the transmission of the services between the UE and the base station requires At least two first AI technologies are used, and the at least two first AI technologies correspond to at least two first resources one-to-one.

[0404]S302. According to the first resource allocation information, on each of the at least two first resources indicated by the first resource allocation information, the UE respectively adopts the first AI technology corresponding to the fi...

Abstract

The embodiment of the invention, which relates to the communication field, provides a resource allocation method and device, and a wireless access system. Using the method, device, and system, the resource utilization rate can increase and the resource utilization ways become flexible. The resource allocation method comprises: a wireless access device determines at least two kinds of first AI technologies needed by service transmission between UE and the wireless access device; the wireless access device allocates at least two first resources corresponding to the at least two kinds of first AI technologies one by one at a first carrier wave, wherein the at least two first resources are used for service transmission between the UE and the wireless access device; and the wireless access device sends first resource allocation information to the UE, wherein the first resource allocation information is used for indicating the first resource corresponding to the first AI technology needed to be employed by the UE receiving the first resource allocation information. The resource allocation method is applied to a screen of resource allocation for UE by a wireless access device.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource allocation method, device and wireless access system. Background technique [0002] With the continuous development of communication technologies, more and more air interface (English: air interface, abbreviation: AI) technologies can be supported by wireless communication systems. [0003] Generally, in a possible application scenario, for example, a user equipment (English: user equipment, abbreviation: UE) needs to simultaneously transmit a multimedia broadcast multicast service (English: multimedia broadcast multicast service, abbreviation: MBMS) and a unicast service (English: unicast), since the AI ​​technology adopted by the UE to transmit MBMS and unicast services (for example, the frame structure adopted by the UE to transmit MBMS and unicast services) is different, it is usually possible to realize UE Simultaneous transmission of MBMS and unicast services. ...
