Information sending method and device and information receiving method and device
Information transmission and reception methods and apparatus are disclosed, where the transmission method includes: carrying configuration information of a control resource set on a physical broadcast channel; where the configuration information is used to indicate to a terminal at least one of the following of the control resource set: time domain position information and frequency domain position information; and transmitting the control resource set to the terminal according to the configuration information.
1. A method, comprising:
transmitting, to a terminal, configuration information of a common control resource set on a physical broadcast channel,
wherein the common control resource set is for remaining minimum system information (RMSI),
the configuration information indicating time domain position information of the common control resource set,
the time domain position information of the common control resource set including: (1) information of a first slot in which the common control resource set is located, (2) a starting symbol index of at least one symbol occupied by the common control resource set in the first slot, and (3) a number of the at least one symbol occupied by the common control resource set in the first slot,
the at least one symbol occupied by the common control resource set in the first slot including at least one of the third symbol, the fifth symbol, the seventh symbol, or the ninth symbol of the first slot; and
transmitting, to the terminal, the common control resource set according to the configuration information.
2. The method of claim 1 , wherein the first slot in which the common control resource set is located contains a synchronization signal block (SSB).
3. The method of claim 2 , wherein the common control resource set is transmitted in a second slot not containing the SSB, and a same resource mapping rule is applied for the common control resource set in both the first slot containing the SSB and the second slot not containing the SSB.
4. The method of claim 2 , wherein the starting symbol index of the at least one symbol occupied by the common control resource set in the first slot and a starting symbol index of symbols occupied by the SSB in the first slot are the same.
5. A method, comprising:
receiving, by a terminal, configuration information of a common control resource set on a physical broadcast channel,
wherein the common control resource set is for remaining minimum system information (RMSI),
the configuration information indicating time domain position information of the common control resource set,
the time domain position information of the common control resource set including: (1) information of a first slot in which the common control resource set is located, (2) a starting symbol index of at least one symbol occupied by the common control resource set in the first slot, and (3) a number of the at least one symbol occupied by the common control resource set in the first slot,
the at least one symbol occupied by the common control resource set in the first slot including at least one of the third symbol, the fifth symbol, the seventh symbol, or the ninth symbol of the first slot; and
receiving, by the terminal, the common control resource set according to the configuration information.
6. The method of claim 5 , wherein the first slot in which the common control resource set is located contains a synchronization signal block (SSB).
7. The method of claim 6 , wherein the common control resource set is transmitted in a second slot not containing the SSB, and a same resource mapping rule is applied for the common control resource set in both the first slot containing the SSB and the second slot not containing the SSB.
8. The method of claim 6 , wherein the starting symbol index of the at least one symbol occupied by the common control resource set in the first slot and a starting symbol index of symbols occupied by the SSB in the first slot are the same.
9. A base station comprising a processor configured to:
transmit, to a terminal, configuration information of a common control resource set on a physical broadcast channel,
wherein the common control resource set is for remaining minimum system information (RMSI),
the configuration information indicating time domain position information of the common control resource set,
the time domain position information of the common control resource set including: (1) information of a first slot in which the common control resource set is located, (2) a starting symbol index of at least one symbol occupied by the common control resource set in the first slot, and (3) a number of the at least one symbol occupied by the common control resource set in the first slot,
the at least one symbol occupied by the common control resource set in the first slot including at least one of the third symbol, the fifth symbol, the seventh symbol, or the ninth symbol of the first slot; and
transmit, to the terminal, the common control resource set according to the configuration information.
10. The base station of claim 9 , wherein the first slot in which the common control resource set is located contains a synchronization signal block (SSB).
11. The base station of claim 10 , wherein the common control resource set is transmitted in a second slot not containing the SSB, and a same resource mapping rule is applied for the common control resource set in both the first slot containing the SSB and the second slot not containing the SSB.
12. The base station of claim 10 , wherein the starting symbol index of the at least one symbol occupied by the common control resource set in the first slot and a starting symbol index of symbols occupied by the SSB in the first slot are the same.
13. A terminal comprising a processor configured to:
receive configuration information of a common control resource set on a physical broadcast channel,
wherein the common control resource set is for remaining minimum system information (RMSI),
the configuration information indicating time domain position information of the common control resource set,
the time domain position information of the common control resource set including: (1) information of a first slot in which the common control resource set is located, (2) a starting symbol index of at least one symbol occupied by the common control resource set in the first slot, and (3) a number of the at least one symbol occupied by the common control resource set in the first slot,
the at least one symbol occupied by the common control resource set in the first slot including at least one of the third symbol, the fifth symbol, the seventh symbol, or the ninth symbol of the first slot; and
receive the common control resource set according to the configuration information.
14. The terminal of claim 13 , wherein the first slot in which the common control resource set is located contains a synchronization signal block (SSB).
15. The terminal of claim 14 , wherein the common control resource set is transmitted in a second slot not containing the SSB, and a same resource mapping rule is applied for the common control resource set in both the first slot containing the SSB and the second slot not containing the SSB.
16. The terminal of claim 14 , wherein the starting symbol index of the at least one symbol occupied by the common control resource set in the first slot and a starting symbol index of symbols occupied by the SSB in the first slot are the same.
