Abstract
A reference signal configuration method, a network side device and a User Equipment (UE) are provided. The reference signal configuration method includes: configuring a reference signal configuration parameter for the UE; and transmitting the reference signal configuration parameter to the UE. The reference signal configuration parameter is used by the UE to transmit a reference signal.
Claims9
A reference signal configuration method used in a network side device, comprising:
- configuring, by the network side device, a reference signal configuration parameter for a User Equipment (UE);
- and
- transmitting, by the network side device, the reference signal configuration parameter to the UE,
- receiving, by the network side device, an uplink control channel reference signal transmitted in accordance with the reference signal configuration parameter from the UE, and
- performing, by the network side device, demodulation of an uplink control channel using the uplink control channel reference signal,
- wherein the reference signal configuration parameter is a control channel reference signal configuration parameter, the control channel reference signal configuration parameter comprises at least one of a minimum frequency domain resource allocation unit of a control channel, and a minimum frequency domain resource allocation unit of a control channel reference signal, and the reference signal configuration parameter is used by the UE to transmit the uplink control channel reference signal,
- wherein the control channel reference signal comprises the uplink control channel reference signal, and the uplink control channel reference signal is used for the demodulation of the uplink control channel,
- wherein the resource occupation symbol of the control channel reference signal comprises at least one symbol beyond the control channel,
- wherein the at least one symbol beyond the control channel comprises at least one symbol adjacent to, and prior to, the control channel, and/or at least one symbol adjacent to, and after, the control channel,
- wherein the resource occupation symbol of the control channel reference signal is a symbol used for detecting interference between the network side devices, or a symbol for detecting interference between the UEs, or a symbol for detecting an uplink service heavy sub-frame, or a symbol for detecting a downlink service heavy sub-frame.

A reference signal configuration method used in a user equipment (UE), comprising:
- receiving a reference signal configuration parameter from a network side device, the reference signal configuration parameter being a control channel reference signal configuration parameter, the control channel reference signal configuration parameter comprising at least one of a minimum frequency domain resource allocation unit of a control channel, and a minimum frequency domain resource allocation unit of a control channel reference signal;
- and
- transmitting an uplink control channel reference signal to the network side device in accordance with the reference signal configuration parameter,
- wherein the control channel reference signal comprises the uplink control channel reference signal, and the uplink control channel reference signal is used for the demodulation of an uplink control channel performed by the network side device,
- wherein the resource occupation symbol of the control channel reference signal comprises at least one symbol beyond the control channel,
- wherein the at least one symbol beyond the control channel comprises at least one symbol adjacent to, and prior to, the control channel, and/or at least one symbol adjacent to, and after, the control channel,
- wherein the resource occupation symbol of the control channel reference signal is a symbol used for detecting interference between the network side devices, or a symbol for detecting interference between the UEs, or a symbol for detecting an uplink service heavy sub-frame, or a symbol for detecting a downlink service heavy sub-frame.
