Abstract

Claims (55)

1. A method for determining information, the method comprising:

receiving first control resource set configuration information sent by a first communication node;

determining corresponding second control resource set configuration information according to a predefined conversion rule and the first control resource set configuration information, by:

determining a mapping relationship between first-type configuration indexes and second-type configuration indexes,

in a case where a configuration index corresponding to the first control resource set configuration information belongs to the first-type configuration indexes, determining a corresponding configuration index of the second-type configuration indexes according to the mapping relationship, and

using configuration information of the corresponding configuration index of the second-type configuration indexes as the second control resource set configuration information; and

receiving system information according to the second control resource set configuration information.

2. The method of claim 1 , wherein determining the mapping relationship between the first-type configuration indexes and the second-type configuration indexes comprises:

predefining the mapping relationship between the first-type configuration indexes and the second-type configuration indexes.

3. The method of claim 1 , wherein determining the corresponding second configuration information according to the predefined conversion rule and the first configuration information further comprises:

adjusting a number of symbols in a control resource set in the second configuration information.

4. The method of claim 3 , wherein adjusting the number of symbols in the control resource set in the second configuration information comprises:

determining a number of symbols in a control resource set corresponding to a second communication node according to a number of resource bocks (RBs) in a control resource set in the first configuration information, a number of RBs in the control resource set in the second configuration information and a number of symbols in the control resource set in the first configuration information.

5. The method of claim 4 , wherein determining the number of symbols in the control resource set corresponding to the second communication node according to the number of RBs in the control resource set in the first configuration information, the number of RBs in the control resource set in the second configuration information and the number of symbols in the control resource set in the first configuration information comprises:

the number of symbols in the control resource set corresponding to the second communication node being a product of a first RB ratio and the number of symbols in the control resource set in the first configuration information, wherein the first RB ratio is a ratio of the number of RBs in the control resource set in the first configuration information to the number of RBs in the control resource set in the second configuration information.

6. The method of claim 4 , wherein determining the number of symbols in the control resource set corresponding to the second communication node according to the number of RBs in the control resource set in the first configuration information, the number of RBs in the control resource set in the second configuration information and the number of symbols in the control resource set in the first configuration information comprises:

the number of symbols in the control resource set corresponding to the second communication node being a larger value between the number of symbols in the control resource set in the second configuration information before adjustment and a product of a first RB ratio and the number of symbols in the control resource set in the first configuration information, wherein the first RB ratio is a ratio of the number of RBs in the control resource set in the first configuration information to the number of RBs in the control resource set in the second configuration information.

7. The method of claim 1 , wherein the system information comprises an access indication information.

8. The method of claim 1 , wherein determining, according to the first control resource set configuration information, a slot position where a physical downlink control channel (PDCCH) is monitored by the second communication node comprises:

calculating, according to the first control resource set configuration information, a slot index corresponding to the second communication node, wherein the slot index is an index, in a radio frame, of a slot where a monitoring occasion of the PDCCH corresponding to the second communication node is located.

9. The method of claim 8 , wherein the slot index is calculated according to the following formula:

n 0 =( O· 2 μ +offset1+└ i·M ┘)mod N slot frame,μ ;

wherein └ ┘ denotes a floor operation, O denotes a first parameter, M denotes a second parameter, offset1 denotes a first preset offset related to M, N slot frame,μ denotes a number of slots comprised in the radio frame, i denotes an index of a synchronization signal block, μ and a subcarrier spacing satisfy a predefined correspondence relationship, and values of the first parameter and the second parameter are acquired from the first control resource set configuration information.

10. A method for indicating information, comprising:

sending first control resource set configuration information to a second communication node; and

sending system information according to second control resource set configuration information determined according to a predefined conversion rule and the first control resource set configuration information,

wherein the second control resource set configuration information is determined according to the predefined conversion rule and the first control resource set configuration information by:

determining a mapping relationship between first-type configuration indexes and second-type configuration indexes;

using configuration information of the corresponding configuration index of the second-type configuration indexes as the second control resource set configuration information.

11. The method of claim 10 , wherein determining the mapping relationship between the first-type configuration indexes and the second-type configuration indexes comprises:

predefining the mapping relationship between the first-type configuration indexes and the second-type configuration indexes.

12. The method of claim 10 , wherein the system information comprises an access indication information.

13. An apparatus for indicating information, comprising:

a memory storing instructions; and

a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the apparatus to perform:

receiving first control resource set configuration information sent by a first communication node,

determining corresponding second control resource set configuration information according to a predefined conversion rule and the first control resource set configuration information, by:

determining a mapping relationship between first-type configuration indexes and second-type configuration indexes,

in a case where a configuration index corresponding to the first control resource set configuration information belongs to the first-type configuration indexes, determining a corresponding configuration index of the second-type configuration indexes according to the mapping relationship, and

using configuration information of the corresponding configuration index of the second-type configuration indexes as the second control resource set configuration information, and

receiving system information according to the second control resource set configuration information.
