Embodiment Construction

[0042] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0043] In order to better understand the embodiments of the present application, the following introduces the technical terms involved in the embodiments of the present application:

[0044] Carrier aggregation (carrier aggregation, CA): It is a technology to increase the transmission bandwidth, which can aggregate two or more component carriers (component carrier, CC), and multiple carriers serve a terminal device at the same time. The terminal device can obtain a larger service bandwidth and correspondingly a larger transmission rate. Wherein, each CC may independently correspond to a cell, that is to say, aggregating one component carrier may be regarded as aggregating one cell. After the terminal device enters the connected state, it can communicate with the access network device through multiple component carriers at the same...

Abstract

Disclosed are a cross-carrier scheduling method and a communication device, which are applied to an access network device. The method comprises the steps of determining a first bit number of first code block group transmission information CBGTI of a first cell; determining a second bit number of a second CBGTI of a second cell, wherein the first cell performs cross-carrier scheduling through the second cell; generating a second CBGTI, wherein a code block group (CBG) of the first cell corresponding to each bit in the second CBGTI is determined based on the first bit number and the second bit number; and sending the second CBGTI to the terminal equipment through the second cell. According to the embodiment of the invention, cross-carrier scheduling between the secondary cell and the primary cell can be realized.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a cross-carrier scheduling method and a communication device. Background technique [0002] Carrier aggregation (carrier aggregation, CA) can aggregate a plurality of component carriers together for the transmission and reception of a single terminal device, and can achieve a higher rate by increasing available frequency resources of the terminal device. Wherein, the component carriers may come from different cells, and if the scheduling grant and the transmission data are sent on different carriers, this situation is called cross-carrier scheduling. [0003] For example, the first cell may perform cross-carrier scheduling through the second cell, and send a physical downlink control channel (physical downlink control channel, PDCCH) of the first cell to the user equipment through the second cell. And the physical downlink shared channel (physical downlink...
