Method and device for indicating PDCCH resources
View Patent ↗Methods and devices for indicating PDCCH resources are provided. The method includes: a network device generates an instruction for PDCCH resources for subframes; the network device sends the instruction for PDCCH resources; a terminal device receives the instruction for PDCCH resources for subframes; the terminal device determines a number of symbols for PDCCH for a MBSFN subframe based on the first instruction and a number of symbols for PDCCH for a non-MBSFN subframe based on the list of indications in the second instruction.
1. A method for indicating PDCCH resources, comprising:
receiving, by a terminal device, an instruction for Physical Downlink Control Channel (PDCCH) resources for subframes; wherein the instruction comprises a first instruction for PDCCH resources for Multicast Broadcast Single Frequency Network (MBSFN) subframes and a second instruction comprising a list of indications for PDCCH resources for non-MBSFN subframes; and
determining, by the terminal device, a number of symbols for PDCCH for a MBSFN subframe based on the first instruction and a number of symbols for PDCCH for a non-MBSFN subframe based on the list of indications in the second instruction; wherein the first instruction comprises a single indication of the number of symbols for PDCCH;
wherein determining the number of symbols for PDCCH for the non-MBSFN subframe based on the list of indications in the second instruction comprises:
using the list of indications in the second instruction sequentially and periodically to determine the number of symbols for PDCCH for the non-MBSFN subframe.
2. The method according to claim 1 , wherein different MBSFN subframes have a same number of symbols for PDCCH.
3. The method according to claim 1 , wherein a number of indications in the list of indications in the second instruction is not same as the period of the MBSFN subframe.
4. A terminal device, comprising: a processor and a transceiver, wherein
the transceiver is configured to receive an instruction for Physical Downlink Control Channel (PDCCH) resources for subframes; wherein the instruction comprises a first instruction for PDCCH resources for Multicast Broadcast Single Frequency Network (MBSFN) subframes and a second instruction comprising a list of indications for PDCCH resources for non-MBSFN subframes;
the processor is configured to determine a number of symbols for PDCCH for a MBSFN subframe based on the first instruction and a number of symbols for PDCCH for a non-MBSFN subframe based on the list of indications in the second instruction; and
the first instruction comprises a single indication of the number of symbols for PDCCH;
wherein the processor is configured to use the list of indications in the second instruction sequentially and periodically to determine the number of symbols for PDCCH for the non-MBSFN subframe.
5. The terminal device according to claim 4 , wherein different MBSFN subframes have a same number of symbols for PDCCH.
6. The terminal device according to claim 4 , wherein a number of indications in the list of indications in the second instruction is not same as a period of the MBSFN subframe.
7. A method for indicating PDCCH resources, comprising:
generating, by a network side device, an instruction for Physical Downlink Control Channel (PDCCH) resources for subframes; wherein the instruction comprises a first instruction for PDCCH resources for Multicast Broadcast Single Frequency Network (MBSFN) subframes and a second instruction comprising a list of indications for PDCCH resources for non-MBSFN subframes; and
sending, by the network side device, the instruction for PDCCH resources to a terminal device; wherein the first instruction comprises a single indication of the number of symbols for PDCCH;
wherein the method further comprises:
sending, by the network side device, a rule to use the list of indications in the second instruction sequentially and periodically to the terminal device.
8. The method according to claim 7 , wherein different MBSFN subframes have a same number of symbols for PDCCH.
9. The method according to claim 7 , wherein a number of indications in the list of indications in the second instruction is not same as the period of the MBSFN subframe.
10. A network side device, comprising: a processor and a transceiver, wherein
the processor is configured to generate an instruction for Physical Downlink Control Channel (PDCCH) resources for subframes; wherein the instruction comprises a first instruction for PDCCH resources for Multicast Broadcast Single Frequency Network (MBSFN) subframes and a second instruction comprising a list of indications for PDCCH resources for non-MBSFN subframes;
the transceiver is configured to send the instruction for PDCCH resources to a terminal device; and
the first instruction comprises a single indication of the number of symbols for PDCCH;
wherein the transceiver is configured to send a rule to use the list of indications in the second instruction sequentially and periodically to the terminal device.
11. The network side device according to claim 10 , wherein different MBSFN subframes have a same number of symbols for PDCCH.
