Information receiving method, information sending method, terminal, and network-side device

A terminal, comprising a processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, the following steps are implemented:

• performing synchronization signal/physical broadcast channel signal block (SSB) detection;
• determining, based on transmission configuration information for first information, a candidate SSB set quasi co-located with a detected first SSB, wherein the first information comprises a SSB;
• and
• performing first processing based on the first SSB and the candidate SSB set, wherein the first processing comprises one of the following:
• receiving system information scheduled by a physical control channel associated with the first SSB;
• performing radio link monitoring;
• and
• performing radio resource management measurement;
• wherein the transmission configuration information comprises at least one of the following:
• positions of SSBs and positions of first search spaces for physical control channels associated with the SSBs in slot;
• the number n of search spaces for physical control channels in one slot, wherein n is a positive integer greater than or equal to 1;
• a period T of a candidate transmission time window;
• a length L of a candidate transmission time window;
• a quasi co-location factor q for SSBs in a candidate transmission time window;
• or
• the number and/or positions of SSBs sent in one slot, wherein
• the candidate transmission time window is a time window for transmitting the first information;
• wherein the determining, based on transmission configuration information for first information, a candidate SSB set quasi co-located with a detected first SSB comprises:
• determining a candidate transmission time window set based on the transmission configuration information and an index i of the first SSB;
• and
• determining, in the candidate transmission time window set, position of the candidate SSB set quasi co-located with the first SSB.

A network-side device, comprising a processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, the following steps are implemented:

• performing clear channel detection in a candidate transmission time window, wherein the candidate transmission time window is a time window for transmitting first information;
• and
• sending the first information on a detected clear channel based on transmission configuration information for the first information, wherein the first information comprises synchronization signal/physical broadcast channel signal blocks SSBs, and the SSB carries the transmission configuration information;
• wherein the transmission configuration information comprises at least one of the following:
• positions of SSBs and positions of first search spaces for physical control channels associated with the SSBs in a slot;
• the number n of search spaces for physical control channels in one slot, wherein n is a positive integer greater than or equal to 1;
• a period T of a candidate transmission time window;
• a length L of a candidate transmission time window;
• a quasi co-location factor for SSBs in a candidate transmission time window;
• or
• the number and/or positions of SSBs sent in one slot, wherein
• the candidate transmission time window is a time window for transmitting the first information;
• wherein the transmission configuration information causes a terminal to determine a candidate transmission time window set based on an index i of a detected first SSB, and determine, in the candidate transmission time window set, a position of a candidate SSB set quasi co-located with the first SSB.
