Abstract

A carrier grouping method and device, the method comprising: a network device divides multiple carriers configured for a terminal into at least one first-type carrier group, so that the network device carries control information corresponding to the first carrier on a second carrier sent to the terminal, the first carrier and the second carrier belong to the same first-type carrier group, and when multiple carriers in at least two first-type carrier groups are scheduled, the terminal combines the feedback information corresponding to the multiple carriers in one Carrier aggregation feeds back to network devices. The network device sends the first group configuration information to the terminal, where the first group configuration information is used to indicate a grouping result of at least one carrier group of the first type. Through the above method, the decoupling of carrier groups based on cross-carrier feedback division and carrier group division based on cross-carrier scheduling can simplify carrier aggregation scheduling of network devices under different numerology carrier aggregation, and can also avoid terminal power limitation.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a carrier grouping method and device. Background technique [0002] In order to better meet the growing demands of service types, new access technologies (such as 5G technology) are required to support Enhanced Mobile Broadband (eMBB) and broadcast In addition to the business, two new business types, Ultra-Reliable and Low Latency Communications (URLLC) and massive Machine Type Communication (mMTC), were introduced. Among them, the service characteristics, reliability requirements or delay requirements of each service type are obviously different, so each service has different requirements for system parameters such as subcarrier spacing, symbol length, and time unit. In addition, 5G supports sub 6G (such as 700M or 3.5G), above 6G (such as 28G or 40G, etc.) frequency bands, and different frequency bands also need to be configured with different syst...
