Channel state information reporting method and device, and channel state information receiving method and device

A channel state information receiving method, applied to a second communication node, wherein the second communication node comprises a base station, wherein the method comprises:

• sending a reference signal to a first communication node;
• and
• receiving at least one of a first type channel state information set or a second type channel state information set which is determined by the first communication node according to a first type reporting configuration signaling associated with the reference signal, wherein the first communication node comprises a user equipment;
• wherein the first type channel state information set comprises at least one of:
• a reference signal resource index, a reference signal resource set index, a reference signal resource configuration index, a reporting configuration index, a reference signal port group index, a reference signal port group set index, a port index, or rank indicator information;
• wherein the second type channel state information set comprises at least one of:
• precoding matrix indicator information, channel quality indicator information, an amplitude coefficient, a phase coefficient, or a reference signal received power;
• wherein the first type reporting configuration signaling is configured according to following rules:
• under different reference signal resource configurations, reporting reference signal resource indexes from the different reference signal resource configurations at a same time;
• and
• under a same reference signal resource configuration, reporting no more than U3 or U3 reference signal resource indexes from the same reference signal resource configuration, wherein U3 is an integer greater than or equal to 1;
• and
• wherein the different reference signal configurations correspond to different panels located at the base station.

A channel state information reporting apparatus, provided at a first communication node, wherein the first communication node comprises a user equipment, wherein the apparatus comprises:

• a processor;
• a memory for storing processor-executable instructions;
• wherein the processor is configured to:
• receive a reference signal sent by a second communication node;
• and
• determine, according to a first type reporting configuration signaling associated with the reference signal, at least one of a first type channel state information set or a second type channel state information set, and report the at least one of the first type channel state information set or the second type channel state information set to the second communication node, wherein the second communication node comprises a base station;
• wherein the first type channel state information set comprises at least one of:
• a reference signal resource index, a reference signal resource set index, a reference signal resource configuration index, a reporting configuration index, a reference signal port group index, a reference signal port group set index, a port index, or rank indicator information;
• and
• wherein the second type channel state information set comprises at least one of:
• precoding matrix indicator information, channel quality indicator information, an amplitude coefficient, a phase coefficient, or a reference signal received power;
• wherein the processor is configured to report the reference signal resource index according to following rules:
• under different reference signal resource configurations, reporting reference signal resource indexes from the different reference signal resource configurations at a same time;
• and
• under a same reference signal resource configuration, reporting no more than U3 or U3 reference signal resource indexes from the same reference signal resource configuration, wherein U3 is an integer greater than or equal to 1;
• and
• wherein the different reference signal configurations correspond to different panels located at the base station.
