3. The method of claim 1 , wherein the sidelink channel resource pattern table is one of the following: pre-configured by the system, and configured by a wireless communication node.

4. The method of claim 1 , wherein the plurality of sidelink channel resource configuration patterns each is used to indicate a configuration of at least one sidelink channel resource unit of at least one sidelink channel.

5. The method of claim 4 , wherein the configuration of the sidelink channel resource unit comprises at least one of following: a first number of first resource units in the time domain, a second number of second resource units in the frequency domain, a first starting position in the time domain, and a second starting position in the frequency domain, wherein the first starting position in the time domain is one of the following in a time slot, a starting symbol and a starting available symbol for sidelink communications, and wherein the second starting position in the frequency domain is one of the following: a starting resource block (RB) and a starting available RB for sidelink communications.

6. The method of claim 4 , wherein the configuration of the at least one sidelink channel resource unit comprises: a symbol type for each of the first resource units in the time domain of the at least one respective sidelink channel resource unit, wherein the symbol type for each of the first resource units is one of following: an effective sidelink channel resource symbol, a reference signal (RS) symbol, a guard period (GP) symbol, a reserved symbol, and a non-sidelink symbol.

7. The method of claim 1 , wherein the performing further comprises:

indicating a pattern index of the sidelink channel resource pattern table, wherein the pattern index corresponds to one of the plurality of sidelink channel resource configuration patterns.

8. A method performed by a wireless communication node, comprising:

indicating a sidelink channel resource pattern table to a wireless communication devices; and

wherein:

the sidelink channel resource pattern table comprises a plurality of sidelink channel resource configuration patterns, one of which indicates a configuration of the sidelink channel resource unit,

the configuration of the sidelink channel resource unit comprises a plurality of symbols in a time slot, and

the plurality of symbols in the time slot comprise a symbol for an automatic gain control (AGC).

9. The method of claim 8 , wherein the sidelink channel comprises at least one of the following: a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), a Physical Sidelink Broadcast Channel (PSBCH), and a Physical Sidelink Discovery Channel (PSDCH).

10. The method of claim 8 , wherein the sidelink channel resource pattern table is one of the following: pre-configured by the system, and configured by a wireless communication node.

11. The method of claim 8 , wherein the plurality of sidelink channel resource configuration patterns each is used to indicate a configuration of at least one sidelink channel resource unit of at least one sidelink channel.

12. The method of claim 11 , wherein the configuration of the sidelink channel resource unit comprises at least one of following: a first number of first resource units in the time domain, a second number of second resource units in the frequency domain, a first starting position in the time domain, and a second starting position in the frequency domain, wherein the first starting position in the time domain is one of the following in a time slot, a starting symbol and a starting available symbol for sidelink communications, and wherein the second starting position in the frequency domain is one of the following: a starting resource block (RB) and a starting available RB for sidelink communications.

13. The method of claim 11 , wherein the configuration of the at least one sidelink channel resource unit comprises: a symbol type for each of the first resource units in the time domain of the at least one respective sidelink channel resource unit, wherein the symbol type for each of the first resource units is one of following: an effective sidelink channel resource symbol, a reference signal (RS) symbol, a guard period (GP) symbol, a reserved symbol, and a non-sidelink symbol.

14. The method of claim 8 , wherein indicating further comprises:

indicating a pattern index of the sidelink channel resource pattern table to the wireless communication device.

15. A computing device comprising at least one processor and a memory coupled to the processor, the at least one processor configured to carry out the method of claim 1 .

16. A non-transitory computer-readable medium having stored thereon computer-executable instructions for carrying out the method of claim 1 .

17. A computing device comprising at least one processor and a memory coupled to the processor, the at least one processor configured to carry out the method of claim 2 .

18. A computing device comprising at least one processor and a memory coupled to the processor, the at least one processor configured to carry out the method of claim 8 .

19. A computing device comprising at least one processor and a memory coupled to the processor, the at least one processor configured to carry out the method of claim 9 .

20. A non-transitory computer-readable medium having stored thereon computer-executable instructions for carrying out the method of claim 8 .
