Embodiment Construction

[0111] First, the technical terms and application scenarios involved in this application are introduced.

[0112] In a single-carrier scenario, taking LTE as an example, the network device configures frequency resources, which are used for downlink transmission and uplink transmission, and there is a predefined correspondence between the uplink frequency resources and the downlink frequency resources. For example, for frequency division duplex (frequency domain duplex, FDD) spectrum, downlink transmission and uplink transmission use different frequency resources. For time-division duplex (time domain duplex, TDD) spectrum, downlink transmission and uplink transmission use the same frequency resource. At this time, the network device performs downlink transmission and the communication device performs uplink on the same frequency domain resource based on time division multiplexing. transmission.

[0113] In the CA scenario of NR, when the network device configures frequency re...

Abstract

The present application discloses a method and equipment for indicating carrier status, which are used to support the activation and deactivation of carriers in NR. The method includes: the communication device communicates with network equipment on the first uplink carrier based on the first downlink carrier, and The device receives the carrier status indication information sent by the network equipment, the carrier status indication information indicates the carrier status of M carriers corresponding to the cell where the N network equipment provides services for the communication device, the carrier status includes activation status and deactivation status, and the carrier status indication information Indicate that the first downlink carrier is in a deactivated state, the first uplink carrier is in an activated state, and both the first downlink carrier and the first uplink carrier are carriers in the M carriers. Therefore, flexible carrier activation and deactivation in NR can be realized by adopting the method provided in this application.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a carrier state indicating method and device. Background technique [0002] The continuous growth of smart terminal users, the continuous increase of user traffic and data throughput, put forward higher requirements for communication speed. However, due to the shortage of wireless spectrum resources, it is difficult to find continuous large bandwidth for mobile communication. Therefore, the Carrier Aggregation (CA) technology is introduced into the Long Term Evolution (LTE) communication system, and multiple continuous or discontinuous spectrums are aggregated to solve the technical problem of mobile communication for large bandwidth. demand, while also improving the utilization of fragmented spectrum in the wireless band. [0003] In the fifth generation (the 5th generation, 5G) new wireless communication protocol (new radio, NR), CA is also a nece...
