Method and apparatus for configuring PRS resources

1. A method for configuring Positioning Reference Signal (PRS) resources, comprising:

receiving, by User Equipment (UE), configuration information for a PRS resource set from a network device, wherein the configuration information comprises a respective PRS muting configuration for each PRS resource in the PRS resource set, and different PRS muting configurations are configured for different PRS resources in the PRS resource set,

wherein the PRS muting configuration for each PRS resource in the PRS resource set comprises:

a second parameter configured to determine muting configuration on PRS repetitions within one PRS period; and wherein the muting configuration on PRS repetitions within one PRS period is used to indicate a slot, among a number of slots for repetitions of the PRS resource within one PRS period, in which the PRS transmission of the PRS resource shall be muted; and wherein the muting configuration on PRS repetitions within one PRS period is a bit string with a length equaling to the number of slots for repetitions of the PRS resource within one PRS period, and each bit in the bit string corresponds to one slot in the slots for repetitions of the PRS resource within one PRS period.

2. The method of claim 1 , wherein the PRS muting configuration for each PRS resource in the PRS resource set further comprises:

a first parameter configured to determine a periodic muting sequence.

3. The method of claim 2 , wherein the periodic muting sequence is used to indicate in which PRS period a PRS transmission of the PRS resource shall be muted, and the periodic muting sequence is a bit string of length N, N being a positive integer.

4. The method of claim 3 , wherein each bit in the periodic muting sequence represents whether the PRS transmission of the PRS resource in the corresponding PRS period shall be muted or not.

5. The method of claim 1 , wherein each PRS resource in the PRS resource set is associated with a respective beam.

6. A method for configuring Positioning Reference Signal (PRS) resources, comprising:

transmitting, by a network device, configuration information for a PRS resource set to User Equipment (UE), wherein the configuration information comprises a respective PRS muting configuration for each PRS resource in the PRS resource set, and different PRS muting configurations are configured for different PRS resources in the PRS resource set,

wherein the PRS muting configuration for each PRS resource in the PRS resource set comprises:

a second parameter configured to determine muting configuration on PRS repetitions within one PRS period; and wherein the muting configuration on PRS repetitions within one PRS period is used to indicate a slot, among a number of slots for repetitions of the PRS resource within one PRS period, in which the PRS transmission of the PRS resource shall be muted; and wherein the muting configuration on PRS repetitions within one PRS period is a bit string with a length equaling to the number of slots for repetitions of the PRS resource within one PRS period, and each bit in the bit string corresponds to one slot in the slots for repetitions of the PRS resource within one PRS period.

7. The method of claim 6 , wherein the PRS muting configuration for each PRS resource in the PRS resource set further comprises:

a first parameter configured to determine a periodic muting sequence.

8. The method of claim 7 , wherein the periodic muting sequence is used to indicate in which PRS period a PRS transmission of the PRS resource shall be muted, and the periodic muting sequence is a bit string of length N, N being a positive integer.

9. The method of claim 8 , wherein each bit in the periodic muting sequence represents whether the PRS transmission of the PRS resource in the corresponding PRS period shall be muted or not.

10. The method of claim 6 , wherein each PRS resource in the PRS resource set is associated with a respective beam.

11. An apparatus for configuring Positioning Reference Signal (PRS) resources, comprising:

a transceiver;

a processor; and

a memory for storing a computer program,

wherein the processor is configured to execute the computer program stored in the memory to:

control the transceiver to receive configuration information for a PRS resource set from a network device, wherein the configuration information comprises a respective PRS muting configuration for each PRS resource in the PRS resource set, and different PRS muting configurations are configured for different PRS resources in the PRS resource set,

wherein the PRS muting configuration for each PRS resource in the PRS resource set comprises:

a second parameter configured to determine muting configuration on PRS repetitions within one PRS period; and wherein the muting configuration on PRS repetitions within one PRS period is used to indicate a slot, among a number of slots for repetitions of the PRS resource within one PRS period, in which the PRS transmission of the PRS resource shall be muted; and wherein the muting configuration on PRS repetitions within one PRS period is a bit string with a length equaling to the number of slots for repetitions of the PRS resource within one PRS period, and each bit in the bit string corresponds to one slot in the slots for repetitions of the PRS resource within one PRS period.

12. The apparatus of claim 11 , wherein the PRS muting configuration for each PRS resource in the PRS resource set further comprises:

a first parameter configured to determine a periodic muting sequence.

13. The apparatus of claim 12 , wherein the periodic muting sequence is used to indicate in which PRS period a PRS transmission of the PRS resource shall be muted, and the periodic muting sequence is a bit string of length N, N being a positive integer.

14. The apparatus of claim 13 , wherein each bit in the periodic muting sequence represents whether the PRS transmission of the PRS resource in the corresponding PRS period shall be muted or not.
