Beam recovery processing method, beam recovery method, and device, system and medium

A beam recovery method, comprising:

• receiving, by a receiving end, a configuration information set for instructing the receiving end to perform a beam recovery and transmitted by a transmitting end;
• performing, by the receiving end, the following operations according to the configuration information set:
• the receiving end determines first configuration information used for beam quality monitoring according to the configuration information set, and performs the beam quality monitoring according to the first configuration information;
• determining, by the receiving end, second configuration information used for the beam selection according to the configuration information set;
• and
• when a new beam needs to be selected, performing, by the receiving end, the beam selection according to the second configuration information;
• wherein the second configuration information comprises configuration information of a second reference pilot resource set for the beam selection;
• wherein the receiving end determines the configuration information of the second reference pilot resource set according to at least one of:
• a configuration signaling of the transmitting end;
• an RRC state;
• a configuration of a reporting manner for the beam recovery information;
• a beam recovery mode;
• a configuration of a first reference pilot resource set;
• a transmission configuration of a control channel, a measurement result of the beam quality monitoring;
• or a configuration of a first set of preset conditions;
• wherein in a case where the receiving end determines the configuration information of the second reference pilot resource set according to the RRC state, a plurality of RRC states are divided into multiple sets, and the second reference pilot resource set or the subset of the second reference pilot resource set are separately configured for each set of the plurality of RRC states.

A communication system, comprising:

• a base station and a terminal;
• wherein the base station determines a configuration information set for instructing the terminal to perform a beam recovery;
• wherein the configuration information set comprises:
• a second configuration information set, used for instructing the terminal to perform a beam selection according to the second configuration information set;
• and
• the base station transmits the configuration information set to the terminal;
• wherein the second configuration information set comprises:
• configuration information of a second reference pilot resource set used for the beam selection;
• wherein the base station determines the configuration information set for instructing the terminal to perform the beam recovery comprises:
• the base station configures at least one of the following information for the terminal separately for different radio resource control (RRC) state sets:
• the second reference pilot resource set or a subset of the second reference pilot resource set, wherein a plurality of RRC states are divided into multiple sets, and the second reference pilot resource set or the subset of the second reference pilot resource set are separately configured for each set of the plurality of RRC states;
• or
• the base station configures a plurality of control channels, and configures at least one of the following information separately for different control channels:
• the second reference pilot resource set or a subset of the second reference pilot resource set, wherein the plurality of control channels are divided into multiple sets, and the second reference pilot resource set or the subset of the second reference pilot resource set are separately configured for each set of the plurality of control channels.
