Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0030] According to the current NR design and protocol regulations, carrier aggregation and bandwidth part (BWP) technologies are used for the use of large bandwidth. One or more large bandwidths are divided into multiple carriers, and multiple BWPs can be configured in each carrier. Each BWP is a plurality of continuous PRBs (Physical Resource Block...

Abstract

The invention discloses an uplink channel indication method and equipment. The method comprises the following steps: monitoring a frequency band on a carrier of an unlicensed frequency band; selectinga target carrier and a target frequency band according to the monitoring result and used for sending a PUCCH or a PUSCH; and sending indication information for identifying the target carrier and thetarget frequency band. The invention further comprises terminal equipment and a system applying the method. The problems of system resource waste and low working efficiency are solved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to an uplink channel indication method and device. Background technique [0002] 5G has now become the latest generation of mobile communication technology, and various extended applications based on 5G will gradually flourish. An important application of 5G is the use of unlicensed frequency bands. Compared with the licensed frequency band, the unlicensed frequency band needs to consider the coexistence and use of various wireless systems. Typical applications in unlicensed frequency bands such as Wifi, LTE-based LAA technology, etc. In order to allow multiple technologies to coexist harmoniously, the use of unlicensed frequency bands adopts mandatory listen-before-transmit technology (LBT), that is, data can only be sent when the current channel is detected to be unoccupied. [0003] The problem brought about by this mechanism is that some data cannot...
