Embodiment Construction

[0099] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0100] The technology described in this application can adopt wireless communication systems of various wireless access technologies, such as code division multiple access (code division multiple access, CDMA), frequency division multiple access (frequency division multiple access, FDMA), time division multiple access (time division multiple access) Division multiple access, TDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (single carrier-frequency division multiple access, SC-FDMA) and other access technology systems are also applicable For subsequent evolution systems, such as the fifth generation 5G (also called new radio (new radio, NR)) system and the like.

[0101] The network elements involved in this embodiment of the present application include network devices and terminals. A network device ...

Abstract

The invention relates to a carrier grouping method and device. The method includes the following steps that: a network device classifies a plurality of carriers configured for a terminal as at least one first type carrier group, so that the network device loads control information corresponding to a first carrier on a second carrier and sends the second carrier to the terminal, wherein the first carrier and the second carrier belong to the same first type carrier group; when a plurality of carriers in at least two first type carrier groups are scheduled, the terminal aggregates converges feedback information corresponding to the plurality of carriers on one carrier and feeds back the carrier to the network device; and the network device sends first grouping configuration information to theterminal, wherein the first grouping configuration information is used to indicate the grouping result of the at least one first type carrier group. With the above method adopted, the carrier aggregation scheduling of the network device under different numerology carrier aggregation can be simplified on the basis of the decoupling of a cross-carrier feedback division carrier group and a cross-carrier scheduling division-based carrier group.

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...
