Embodiment Construction

[0137] In order to facilitate understanding of the embodiments of the present application, the terms involved in the present application are firstly introduced.

[0138] Carrier: Unless otherwise specified, the carrier in the embodiments of this application refers to a continuous segment of frequency spectrum in the frequency domain. For example, under the 3GPP NR protocol, the carrier is equivalent to the carrier (carrier) or component carrier (component carrier, CC) defined in 3GPP NR, and the carrier can also refer to a bandwidth part (band width part, BWP), and the carrier can also refer to A generation corresponds to a cell, a channel channel, a sub-channel sub-channel, one or more resource blocks (resource block, RB), resource block group (resource block group, RBG), the resource block group can be physically Continuous, such as a physical resource block (physical resource lock, PRB), or physically discontinuous, but mapped to a virtual continuous resource through a cert...

Abstract

Disclosed in an embodiment of the present application is a capability information reporting method for a communication system. The method comprises the steps that first equipment determines the capability information of the first equipment, wherein the capability information is used for indicating a capability of a maximum aggregation spectrum supported by the first device in a first range; and the first equipment sends the capability information. According to the embodiment of the invention, the cost of the first equipment is reduced by sending the capability information containing the maximum aggregation spectrum.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular to a method and a device for reporting capability information. Background technique [0002] Carrier aggregation (CA) is a technology to increase the transmission bandwidth. In the system, carrier aggregation is introduced, so that a terminal device can perform data transmission on multiple carriers at the same time. [0003] In the prior art, the capability information of the UE is determined according to the number of carriers supported by the user equipment (UE) and the maximum channel bandwidth supported by each carrier. remaining information. In the carrier aggregation scenario, when the UE reports carrier aggregation capability information, according to the existing protocol, the UE bases each carrier in the frequency band (in carrier aggregation, the carrier participating in the aggregation is also called component carrier (component...
