Problems solved by technology

However, if the terminal device fails to detect the DCI that triggers A-CSI, the network device's understanding of the uplink control information (UCI) jointly fed back will be inconsistent with that of the terminal device, resulting in a reception error

Embodiment Construction

[0073] The technology described in the embodiments of this application can be used in various communication systems, such as long term evolution (long termevolution, LTE) system, new radio (New Radio, NR) system and evolved LTE (evolved LTE, eLTE) system and other 5G (the fifth generation (fifth generation) system, or other next generation (next generation, NG) communication system.

[0074] figure 1 It is a schematic diagram of a communication system 100 provided in an embodiment of the present application.

[0075] Such as figure 1 As shown, the communication system 100 includes a network device 110 and a terminal device 120 . The terminal device 120 communicates with the network device 110 through electromagnetic waves. When the terminal device 120 sends information, the wireless communication module of the terminal device 120 can obtain the information bits to be sent to the network device 110 through the channel. These information bits are, for example, generated by th...

Abstract

The invention provides a communication method, a communication device and a storage medium. The method comprises the steps that terminal equipment determines uplink information; when the uplink information is first feedback information, the terminal equipment determines a first uplink control channel resource corresponding to the first feedback information and sends the first feedback informationon the first uplink control channel resource; when the uplink information comprises aperiodic channel state information (A-CSI); and the terminal equipment determines a second uplink control channel resource corresponding to the uplink information and sends the uplink information on the second uplink control channel resource, wherein the first uplink control channel resource is different from thesecond uplink control channel resource, so that the network equipment identifies whether the uplink information contains the A-CSI or not through the control channel resource used by the received uplink information, the uplink information can be correctly received, multiple times of blind detection are not needed, and the receiving complexity is low.

Description

technical field [0001] The present application relates to the field of wireless communication, in particular to a communication method, a communication device and a storage medium. Background technique [0002] A next-generation (new generation, NG) mobile communication system supports ultra-reliable and low-latency communications (Ultra-reliable and low latency communications, URLLC) services. URLLC services have high reliability requirements, so the channel state information (CSI) feedback technology is very important. By triggering the aperiodic channel state information (A-CSI) feedback, the channel can be obtained quickly and timely and interference information to help improve the quality of subsequent data transmission. [0003] In order to avoid additional downlink control information (downlink control information, DCI) overhead caused by A-CSI feedback, the prior art proposes A-CSI in uplink control channels, such as short physical uplink control channel (short phys...
