Beam failure recovery request transmission method, reception method, devices and system

A beam failure recovery request reception method, comprising:

• receiving, by a base station, a report message from user equipment (UE);
• determining, by the base station, a message type of the report message in accordance with the report message,
• wherein the message type of the report message comprises a first beam failure recovery request transmitted by the UE to the base station when a quantity of physical downlink control channel (PDCCH) beams that fail is within a preset range and a second beam failure recovery request transmitted by the UE to the base station when all PDCCH beams fail, the preset range is greater than 0 and less than a total quantity of the all PDCCH beams, and the first beam failure recovery request is different from the second beam failure recovery request;
• wherein both the first beam failure recovery request and the second beam failure recovery request comprise indication information, the message type of the report message is determined by the base station in accordance with the indication information in the report message;
• the indication information is used to indicate the message type of the report message, the indication information comprises a signaling bit added in uplink control information (UCI) or an unused state of signaling bit in the UCI, and the indication information in the first beam failure recovery request is different from the indication information in the second beam failure recovery request.

User equipment (UE), comprising a processor, a storage, and a computer program stored in the storage and configured to be executed by the processor, wherein the processor is configured to execute the computer program, to implement following steps:

• detecting whether each physical downlink control channel (PDCCH) beam of all PDCCH beams fails, wherein the all PDCCH beams are PDCCH beams configured by a base station for the UE to monitor;
• if it is determined that a quantity of PDCCH beams that fail is within a preset range, transmitting a first beam failure recovery request to the base station, wherein the preset range is greater than 0 and less than a total quantity of the all PDCCH beams;
• if it is determined that the all PDCCH beams fail, transmitting a second beam failure recovery request to the base station,
• wherein the second beam failure recovery request is different from the first beam failure recovery request;
• wherein both the first beam recovery requestand the second beam failure recovery request comprise indication information for indicating a message type of a report message, the indication information comprises a signaling bit added in uplink control information (UCI) or an unused state of a signaling bit in the UCI;
• and the indication information in the first beam failure revoery request is different from the indication information in the second beam failure recovery request.
