Abstract
A reference signal transmission method is disclosed, the method including: determining at least two first reference signal resources; receiving a first channel based on the at least two first reference signal resources when a scheduling offset is less than or equal to a preset threshold and/or there is no spatial relation parameter information indication field in downlink control information DCI; and demodulating the first channel. When data on at least two reference signal resources needs to be received within a period of time, the method can increase a probability that a terminal device successfully receives the data.
Claims14
A signal transmission method, comprising:
- determining at least two first reference signal resources;
- receiving a first channel based on a first target reference signal resource in response to a scheduling offset being less than or equal to a preset threshold, wherein the first target reference signal resource belongs to the at least two first reference signal resources and is determined based on first information, and wherein the first information is information about downlink control information (DCI) for scheduling the first channel, wherein the first target reference signal resource is a reference signal resource corresponding to a control resource set (CORESET) that is in a slot closest to the first channel and that has a smallest index value in CORESETs having an association relationship with the first information, and wherein the first channel carries a first type of data and a second type of data, wherein the first target reference signal resource is used to demodulate the first type of data;
- and
- determining a second target reference signal resource from the at least two first reference signal resources, wherein the second target reference signal resource is used to demodulate the second type of data.
An apparatus, comprising:
- at least one processor configured to determine at least two first reference signal resources;
- and
- a transceiver is configured to:
- receive a first channel based on a first target reference signal resource in response to a scheduling offset being less than or equal to a preset threshold, wherein the first target reference signal resource belongs to the at least two first reference signal resources and is determined based on first information, and wherein the first information is information about downlink control information (DCI) for scheduling the first channel, wherein the first target reference signal resource is a reference signal resource corresponding to a control resource set (CORESET) that is in a slot closest to the first channel and that has a smallest index value in CORESETs having an association relationship with the first information, and wherein the first channel carries a first type of data and a second type of data, wherein the first target reference signal resource is used to demodulate the first type of data:
- wherein the at least one processor is further configured to:
- determine a second target reference signal resource from the at least two first reference signal resources, wherein the second target reference signal resource is used to demodulate the second type of data.
