Abstract

Claims (43)

1. A downlink transmission sending method, applicable to a base station, comprising:

for a downlink transmission in N repetitions, in response to determining that a repetition overlaps with second transmission resources of one or more synchronization signal blocks,

canceling sending the downlink transmission on first transmission resources, delaying sending the M repetitions corresponding to the first transmission resources, so that the downlink transmission comprises a total of N repetitions; wherein M is a positive integer less than N; or

sending the downlink transmission by puncturing the first transmission resources;

wherein the first transmission resources are for the repetition and overlap with the second transmission resources of the one or more synchronization signal blocks over at least one resource element (RE);

wherein sending the downlink transmission by puncturing the first transmission resources comprises canceling sending a part of the downlink transmission which is mapped onto one or more overlapped resources between the first transmission resources and the second transmission resources; and

wherein N is a positive integer equal to or greater than 2.

2. The method according to claim 1 , further comprising at least one of:

determining, in response to determining that an overlapped status between the first transmission resources and the second transmission resources of the one or more synchronization signal blocks does not meet a preset condition, to cancel sending the downlink transmission on the first transmission resources; and

determining, in response to determining that the overlapped status between the first transmission resources and the second transmission resources of the one or more synchronization signal blocks meets the preset condition, to send the downlink transmission by puncturing the first transmission resources.

3. The method according to claim 2 , wherein the overlapped status between the first transmission resources and the second transmission resources of the one or more synchronization signal blocks meets the preset condition in at least one case of:

a number of REs of one or more overlapped resources between the first transmission resources and the second transmission resources being less than a first threshold; or

a proportion of the one or more overlapped resources between the first transmission resources and the second transmission resources in the first transmission resources being less than a second threshold.

4. The method according to claim 1 , further comprising:

performing, based on an amount of the first transmission resources, a rate matching of sending the downlink transmission in response to sending the downlink transmission by puncturing the first transmission resources.

5. The method according to claim 1 , wherein the downlink transmission comprises at least one of a physical downlink shared channel (PDSCH) transmission or a physical downlink control channel (PDCCH) transmission.

6. A downlink transmission receiving method, applicable to a terminal, comprising:

for a downlink transmission in N repetitions, in response to determining that a repetition overlaps with second transmission resources of one or more synchronization signal blocks,

canceling receiving the downlink transmission on first transmission resources, delaying receiving M repetitions corresponding to the first transmission resources; and performing a data decoding based on the N repetitions; or

receiving the downlink transmission by puncturing the first transmission resources;

wherein the first transmission resources are for the repetition and overlap with the second transmission resources of the one or more synchronization signal blocks over at least one resource element (RE);

wherein receiving the downlink transmission by puncturing the first transmission resources comprises canceling receiving a part of the downlink transmission which is mapped onto one or more overlapped resources between the first transmission resources and the second transmission resources; and

wherein N is a positive integer equal to or greater than 2.

determining, in response to determining that an overlapped status between the first transmission resources and the second transmission resources of the one or more synchronization signal blocks does not meet a preset condition, to cancel receiving the downlink transmission on the first transmission resources; and

determining, in response to determining that the overlapped status between the first transmission resources and the second transmission resources of the one or more synchronization signal blocks meets the preset condition, to receive the downlink transmission by puncturing the first transmission resources.

8. The method according to claim 7 , wherein the overlapped status between the first transmission resources and the second transmission resources of the one or more synchronization signal blocks meets the preset condition in at least one case of:

a number of REs of the one or more overlapped resources between the first transmission resources and the second transmission resources being less than a first threshold; or

a proportion of the one or more overlapped resources between the first transmission resources and the second transmission resources in the first transmission resources being less than a second threshold.

9. The method according to claim 6 , further comprising:

complementing, in response to decoding the downlink transmission received by puncturing the first transmission resources the punctured transmission resources of the first transmission resources using preset data.

10. The method according to claim 9 , wherein complementing, in response to decoding the downlink transmission received by puncturing the first transmission resources, the punctured transmission resources of the first transmission resources using the preset data comprises:

setting a power for receiving punctured transmission resources of the first transmission resources to a preset value in response to decoding the downlink transmission received by puncturing the first transmission resources; or

taking a preset sequence as data symbols carried by the punctured transmission resources of the first transmission resources in response to decoding the downlink transmission received by puncturing the first transmission resources; or

taking a predetermined value as data bits carried by the punctured transmission resources of the first transmission resources in response to decoding the downlink transmission received by puncturing the first transmission resources.
