[0309] In the first embodiment, the mixed transmission of the first service type and the third service type is taken as an example. In this embodiment, the mixed transmission of the eMBB service and the mMTC service is taken as an example.

[0310] In view of the characteristics of the mMTC service, narrowband transmission is used in this embodiment, while eMBB service or URLLC service is transmitted using broadband, such as 20 MHz or other bandwidths. Broadband generally refers to the bandwidth used by the first type of service, such as eMBB service, such as 1.4MHz or 3MHz or 5MHz or 10MHz or 15MHz or 20MHz bandwidth in Long-Term Evolution (LTE), and 5G can support bandwidth above 20MHz. Narrowband generally refers to the bandwidth used by the third service type such as mMTC service, generally less than or equal to the bandwidth used by the first service type such as eMBB service, such as dozens of kHz to several MHz, or a smaller or larger range of bandwidth.

[0336] In the second embodiment, the mixed transmission of the first service type and the second service type is taken as an example. In this embodiment, the mixed transmission of the eMBB service and the URLLC service is taken as an example.

[0337] The business processing method in the second embodiment can adopt the following two methods:

[0338] The first method: because the characteristic of the second service type is low delay, the data packet is generally not very large, such as URLLC service, therefore, URLLC service should have a higher sending priority, when there is a sending demand, it needs to Send immediately or within a short time.

[0339] When no other types of services are sent, URLLC can be sent according to the preset frame format and sending method, and does not involve mixed sending with other types of services.

[0340] When there is a service of the first service type such as eMBB service or a service of a third service type such as mMTC service, the...

[0355] In the third embodiment, the uplink transmission and downlink transmission of mixed services are taken as an example (the implementation of the third embodiment can also be applied to the first embodiment and the second implementation), specifically,

[0356] For the downlink, that is, when the base station is the transmitting end and the UE is the receiving end, the base station can allocate time-frequency resources according to the type of service currently transmitted between the base station and the served UE.

[0357] When the base station is sending data, the eMBB service may not always be mapped to the time-frequency resource where the mMTC pattern and / or URLLC pattern is located; or, only when there is an mMTC service and / or When the URLLC service is sent, the eMBB service is not mapped to the time-frequency resource where the mMTC pattern and / or URLLC pattern is located;

[0358] If no mMTC service and / or URLLC service is sent on the time-frequency resource whe...

Abstract

The invention discloses a service processing method and device. The service processing method comprises the following step that: a transmitting end processes service data on corresponding time frequency resources according to a preset service type pattern, wherein the service data can be a channel or a signal. Through the technical scheme provided by the invention, the problem concerned with simultaneous transmission of a plurality of service types with different features in the same frequency band is solved; transmission of different services in the same frequency band is supported; and meanwhile the problems of collision among different service types and time delay are solved.

Description

technical field [0001] The present invention relates to but not limited to wireless communication technology, especially a service processing method and device. Background technique [0002] In the past few decades, mobile communication has experienced a leap from voice services to high-speed broadband data services. With the further development of new services such as the mobile Internet and the Internet of Things, people's new demands on mobile networks will further increase. On the one hand, it is expected that mobile network data traffic will explode in the future. On the other hand, massive device connections and diverse services and applications are one of the important features of future wireless communication systems, and human-centric communication and machine-centric communication will coexist and develop. [0003] Based on the diverse business and application requirements of future mobile communications, wireless communication systems must meet diverse requireme...
