Abstract
Embodiments of the present disclosure includes example subframe configuration methods and related devices. One example method includes configuring, by a network-side device, a target subframe, where the target subframe includes at least one sounding reference signal (SRS) symbol used to send an SRS signal. The network-side device can then send first configuration signaling to a terminal device, where the first configuration signaling includes a resource configuration of the target subframe or an SRS configuration of the target subframe.
Claims15
A subframe configuration method, comprising:
- configuring, by a network-side device, a target subframe, wherein the target subframe comprises at least one sounding reference signal (SRS) symbol used to send an SRS signal;
- and
- sending, by the network-side device, first configuration signaling to a terminal device, wherein the first configuration signaling comprises a resource configuration of the target subframe or an SRS configuration of the target subframe, wherein the SRS configuration of the target subframe comprises cell-specific SRS configuration information or user-specific SRS configuration information, wherein the cell-specific SRS configuration information is used to identify the SRS symbol in the target subframe, wherein the user-specific SRS configuration information is used to identify an SRS resource that is allocated to the terminal device and that is in the SRS symbol in the target subframe, wherein the SRS resource comprises a time domain resource, a frequency domain resource, or a code domain resource, wherein the time domain resource comprises one or more SRS symbols, and wherein the code domain resource comprises one or more SRS sequences.
A network-side device, comprising:
- at least one processor, the at least one processor configured to configure a target subframe, wherein the target subframe comprises at least one sounding reference signal (SRS) symbol used to send an SRS signal;
- and
- a transceiver, the transceiver configured to send first configuration signaling to a terminal device, wherein the first configuration signaling comprises a resource configuration of the target subframe or an SRS configuration of the target subframe, wherein the SRS configuration of the target subframe comprises cell-specific SRS configuration information or user-specific SRS configuration information, wherein the cell-specific SRS configuration information is used to identify the SRS symbol in the target subframe, wherein the user-specific SRS configuration information is used to identify an SRS resource that is allocated to the terminal device and that is in the SRS symbol in the target subframe, wherein the SRS resource comprises a time domain resource, a frequency domain resource, or a code domain resource, wherein the time domain resource comprises one or more SRS symbols, and wherein the code domain resource comprises one or more SRS sequences.
A terminal device, comprising:
- a transceiver, the transceiver configured to receive first configuration signaling sent by a network-side device, wherein the first configuration signaling comprises a resource configuration of a target subframe or a sounding reference signal (SRS) configuration of the target subframe, wherein the target subframe comprises at least one SRS symbol, wherein the SRS symbol is used to send an SRS signal, wherein the SRS configuration of the target subframe comprises cell-specific SRS configuration information or user-specific SRS configuration information, wherein the cell-specific SRS configuration information is used to identify the SRS symbol in the target subframe, wherein the user-specific SRS configuration information is used to identify an SRS resource that is allocated to the terminal device and that is in the SRS symbol in the target subframe, wherein the SRS resource comprises a time domain resource, a frequency domain resource, or a code domain resource, wherein the time domain resource comprises one or more SRS symbols, and wherein the code domain resource comprises one or more SRS sequences;
- and
- at least one processor, the at least one processor configured to:
- determine the SRS symbol in the target subframe based on the cell-specific SRS configuration information, or determine, based on the user-specific SRS configuration information, the SRS resource that is allocated to the terminal device and that is in the SRS symbol in the target subframe;
- and
- obtain, based on the resource configuration of the target subframe in the first configuration signaling, the target subframe through configuration;
- or
- perform the SRS configuration of the target subframe based on the SRS configuration of the target subframe in the first configuration signaling.
