Abstract

Claims (51)

1 . A user equipment (UE) for wireless communication, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UE to:

receive a first configuration of a first bandwidth part (BWP),

wherein the first configuration includes a first frequency domain location, a first bandwidth, a first cyclic prefix and a first subcarrier spacing (SCS) of the first BWP;

receive a second configuration of a second BWP,

wherein the second configuration includes a BWP identifier and an offset;

determine a second frequency domain location for the second BWP for frequency hopping according to the first configuration and the offset; and

determine a second bandwidth, a second cyclic prefix, and an SCS of the second BWP for frequency hopping according to the first bandwidth, the first cyclic prefix and the first SCS of the first BWP.

2 . The UE of claim 1 , wherein, to determine the second BWP, the at least one processor is configured to cause the UE to:

determine the second frequency domain location of the second BWP for frequency hopping according to the first frequency domain location of the first BWP and the offset.

3 . The UE of claim 2 , wherein the second configuration is without a specific parameter for the second BWP, and wherein to determine the second BWP, the at least one processor is configured to cause the UE to:

determine a parameter for the second BWP according to a corresponding parameter of the first configuration or according to a default parameter, or

determine the second BWP without the specific parameter.

4 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to:

receive a downlink control information (DCI), wherein the DCI includes an indicator of a BWP group for frequency hopping, and the BWP group includes the first BWP and the second BWP; and

hop sequentially among the first BWP and the second BWP of the BWP group.

5 . The UE of claim 2 , wherein the at least one processor is further configured to cause the UE to:

determine a frequency hopping pattern across BWPs.

6 . The UE of claim 5 , wherein the at least one processor is further configured to cause the UE to:

receive a downlink control information (DCI),

wherein the DCI includes an indicator of the frequency hopping pattern, and the indicator indicates a BWP for frequency hopping, or

wherein the DCI includes an indicator of the frequency hopping pattern, and the indicator indicates a BWP pattern for frequency hopping.

7 . The UE of claim 5 , wherein the frequency hopping pattern across BWPs is determined according to a radio resource control (RRC) message.

8 . The UE of claim 1 , wherein the at least one processor is further configured to cause the UE to:

determine a first resource within the first BWP and a second resource within the second BWP;

determine a third resource within the first BWP or within the second BWP according to the first resource and the second resource.

9 . A method, comprising:

receiving a first configuration of a first bandwidth part (BWP),

wherein the first configuration includes a first frequency domain location, a first bandwidth, a first cyclic prefix and a first subcarrier spacing (SCS) of the first BWP;

receiving a second configuration of a second BWP,

wherein the second configuration includes a BWP identifier and an offset; and

determining a second frequency domain location for the second BWP for frequency hopping according to the first configuration and the offset; and

determining a second bandwidth, a second cyclic prefix, and an SCS of the second BWP for frequency hopping according to the first bandwidth, the first cyclic prefix and the first SCS of the first BWP.

10 . The method of claim 9 , wherein determining the second BWP comprises:

determining the second frequency domain location of the specific second BWP for frequency hopping according to the first frequency domain location of the first BWP and the offset.

11 . The method of claim 10 , wherein the second configuration is without a specific parameter for the second BWP, and wherein determining the second BWP comprises:

determining a parameter for the second BWP according to a corresponding parameter of the first configuration or according to a default parameter, or

determining the second BWP without the specific parameter.

12 . The method of claim 9 , further comprising:

receiving a downlink control information (DCI), wherein the DCI includes an indicator of a BWP group for frequency hopping, and wherein the BWP group includes the first BWP and the second BWP; and

hopping sequentially among the first BWP and the second BWP of the BWP group.

13 . The method of claim 9 , further comprising:

determining a frequency hopping pattern across BWPs.

14 . The method of claim 13 , further comprising:

receiving a downlink control information (DCI),

wherein the DCI includes an indicator of the frequency hopping pattern, and the indicator indicates a BWP for frequency hopping, or

wherein the DCI includes an indicator of the frequency hopping pattern, and the indicator indicates a BWP pattern for frequency hopping.

15 . The method of claim 9 , further comprising:

determining a first resource within the first BWP and a second resource within the second BWP;

determining a third resource within the first BWP or within the second BWP according to the first resource and the second resource.
