Embodiment Construction

[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0052] Currently multi-TRP / panel supports two transmission forms, namely single downlink control information (DCI) scheduling and multiple DCI scheduling:

[0053] Single DCI scheduling: schedule a physical downlink shared channel (PDSCH) through a physical downlink control channel (PDCCH);

[0054] Multi-DCI scheduling: through two PDCCHs, one PDSCH is scheduled respectively.

[0055] When multiple DCIs are used for scheduling, multiple PUCCHs may...

Abstract

The present application discloses an information transmission method and device, which are used to determine the reporting mode of PUCCH as joint reporting or independent reporting according to time domain resources and high-level configuration, and transmit PUCCH in the determined reporting mode. On the terminal side, an information transmission method provided by an embodiment of the present application includes: according to the reported time-domain resources and high-level configuration, determine the actual reporting mode of the physical uplink control channel PUCCH, and the actual reporting mode is joint reporting or independent reporting ; Wherein, the high-level configuration includes indication information of the PUCCH reporting method configured by the network side; the PUCCH is transmitted using the reporting method, and the PUCCH carries HARQ feedback information.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to an information transmission method and device. Background technique [0002] In order to improve the coverage at the cell edge and provide a more balanced service quality in the service area, coordinated multi-point is still an important technical means in the new radio (NR) system. From the perspective of network form, network deployment with a large number of distributed access points + centralized baseband processing will be more conducive to providing a balanced user experience rate, and significantly reduce the delay and signaling overhead caused by handover . As the frequency band increases, a relatively dense deployment of access points is also required to ensure network coverage. In the high-frequency band, with the improvement of the integration of active antenna equipment, it will be more inclined to adopt a modular active antenna array. The ante...
