Method and apparatus for using indication information of time domain resource allocation
Various embodiments of the present disclosure provide a method for using indication information of time domain resource allocation. The method comprises receiving indication information of time domain resource allocation from a network node by a terminal device. At least part of the indication information is allowed to at least partly indicate a communication configuration different from the time domain resource allocation. The method further comprises determining the communication configuration for the terminal device, based at least in part on the indication information.
1. A method implemented at a terminal device, comprising:
receiving Downlink Control Information (DCI) from a network node, the DCI conveyed via a Physical Downlink Control Channel (PDCCH) in a control resource set (CORESET); and
determining, based on time domain resource allocation in the DCI, that one or more synchronization signal blocks are not transmitted from the network node to the terminal device, when the one or more synchronization signal blocks are associated with the CORESET overlapping with a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH, wherein the time domain resource allocation is applied to the PDSCH.
2. The method according to claim 1 , wherein a portion of the time domain resource allocation in the DCI comprises synchronization signal scheduling configuration indicating the one or more synchronization signal blocks that are not transmitted, and wherein a further portion of the time domain resource allocation in the DCI indicates scheduling information for the PDSCH.
3. The method according to claim 2 , wherein the synchronization signal scheduling configuration indicates at least one of the following:
one or more synchronization signal block groups, wherein in each group there are one or more synchronization signal blocks that are transmitted from the network node to the terminal device;
one or more synchronization signal blocks that are transmitted from the network node to the terminal device; and
a synchronization signal burst set periodicity.
4. The method according to claim 1 , wherein the time domain resource allocation comprises bits in a time domain resource allocation field of the downlink control information, and wherein one subset of the bits indicates the one or more synchronization signal blocks that are not transmitted and another subset of the bits indicates time domain resources for the PDSCH.
5. An apparatus implemented in a terminal device, comprising:
one or more processors; and
one or more memories comprising computer program codes,
the one or more memories and the computer program codes configured to, upon execution by the one or more processors, cause the apparatus at least to:
receive Downlink Control Information (DCI) from a network node, the DCI conveyed via a Physical Downlink Control Channel (PDCCH) in a control resource set (CORESET); and
determine, based on time domain resource allocation in the DCI, that one or more synchronization signal blocks are not transmitted from the network node to the terminal device, when the one or more synchronization signal blocks are associated with the CORESET overlapping with a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH, wherein the time domain resource allocation is applied to the PDSCH.
6. A method implemented at a network node, comprising:
determining Downlink Control Information (DCI), the DCI conveyed via a Physical Downlink Control Channel (PDCCH) in a control resource set (CORESET), including setting time domain resource allocation in the DCI to indicate that one or more synchronization signal blocks are not transmitted from the network node for a terminal device, when the one or more synchronization signal blocks are associated with the CORESET overlapping with a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH, wherein the time domain resource allocation is applied to the PDSCH; and
transmitting the DCI to the terminal device.
7. The method according to claim 6 , wherein a portion of the time domain resource allocation in the DCI comprises a synchronization signal scheduling configuration that indicates the one or more synchronization signal blocks that are not transmitted.
8. The method according to claim 6 , wherein a further potion of the time domain resource allocation in the DCI indicates scheduling information for the PDSCH.
