Abstract

A method and apparatus for separately configuring sets of frequency resources for a PDCCH and another physical channel are disclosed. According to the method, the first and second messages are configured separately to respectively indicate the sets of frequency resources with associated numerologies for the PDCCH and other physical channels.

First claim

What is claimed is:

1. A method for configuring frequency resources, comprising:
configuring, by a network device, a first message and a second message, wherein the first message indicates a first bandwidth part (BWP) with a first associated numerology for a Physical Downlink Control Channel (PDCCH), and wherein the second message indicates a second BWP with a second associated numerology for a Physical Downlink Sharing Channel (PDSCH); wherein the PDCCH contains scheduling information of the PDSCH, wherein a value of the first associated numerology is different from a value of the second associated numerology, and wherein each of the first and second associated numerologies is at least one of a Subcarrier Spacing (SCS) or a cyclic prefix (CP);
transmitting, by the network device, the first message and the second message;
transmitting, by the network device, the PDCCH in a resource from the first BWP; and
transmitting, by the network device, the PDSCH in a resource from the second BWP.

2. The method according to claim 1 , wherein at least one portion of the first BWP fails to overlap with the second BWP.

3. A method for receiving physical channels, comprising:
receiving, by a User Equipment (UE), a Physical Downlink Control Channel (PDCCH), the PDCCH being transmitted in a resource from a first bandwidth part (BWP) with a first associated numerology, wherein the first BWP with the first associated numerology is indicated by a first message for the PDCCH; and
receiving, by the UE, a Physical Downlink Sharing Channel (PDSCH), the PDSCH being transmitted in a resource from a second BWP with a second associated numerology, wherein the second BWP with the second associated numerology is indicated by a second message for the PDSCH,
wherein the PDCCH contains scheduling information of the PDSCH, wherein a value of the first associated numerology is different from a value of the second associated numerology, and wherein each of the first and second associated numerologies is at least one of a Subcarrier Spacing (SCS) or a cyclic prefix (CP).

4. The method according to claim 3 , wherein at least one portion of the first BWP fails to overlap with the second BWP.

5. An apparatus for configuring frequency resources comprising a processor and a memory storing program instructions, wherein when the program instructions are executed by the processor, the apparatus is configured to:
configure a first message and a second message, wherein the first message indicates a first bandwidth part (BWP) with a first associated numerology for a Physical Downlink Control Channel (PDCCH), wherein the second message indicates a second BWP with a second associated numerology for a Physical Downlink Sharing Channel (PDSCH), wherein the PDCCH contains scheduling information of the PDSCH, wherein a value of the first associated numerology is different from a value of the second associated numerology, and wherein each of the first and second associated numerologies is at least one of a Subcarrier Spacing (SCS) or a cyclic prefix (CP); and
output the first message and the second message, transmit the PDCCH in a resource from the first BWP, and transmit the PDSCH in a resource from the second BWP.

6. The apparatus according to claim 5 , wherein at least one portion of the first BWP fails to overlap with the second BWP.

7. The apparatus according to claim 5 , wherein the first message is one of System Information (SI), a Radio Resource Control (RRC) signaling, or a broadcasting signaling, and the second message is Downlink Control Information (DCI) transmitted in the PDCCH or a following PDCCH.

8. An apparatus for determining frequency resources comprising a processor and a memory storing program instructions, wherein when the program instructions are executed by the processor, the apparatus is configured to:
obtain a Physical Downlink Control Channel (PDCCH), the PDCCH being transmitted in a resource from a first bandwidth part (BWP) with a first associated numerology, wherein the first BWP with the first associated numerology is indicated by a first message for the PDCCH;
obtain a Physical Downlink Sharing Channel (PDSCH), the PDSCH being transmitted in a resource from a second BWP with a second associated numerology, wherein the second BWP with the second associated numerology is indicated by a second message for the PDSCH, wherein the PDCCH contains scheduling information of the PDSCH, wherein a value of the first associated numerology is different from a value of the second associated numerology, and each of the first and second associated numerologies is at least one of a Subcarrier Spacing (SCS) or a cyclic prefix (CP); and
determine the first BWP for the PDCCH and the second BWP for the PDSCH according to the first and second messages.

9. The apparatus according to claim 8 , wherein at least one portion of the first BWP fails to overlap with the second BWP.

10. The apparatus according to claim 8 , wherein the first message is one of SI, a RRC signaling, and a broadcasting signaling and the second message is Downlink Control Information (DCI) transmitted in the PDCCH or a following PDCCH.
