Abstract
Provided are method and devices which apply an optimal DMRS configuration for each slot unit to which a DMRS is allocated, and guarantee both resources for data transmission of a PDSCH/PUSCH and stability of transmission or reception based on the accuracy of channel estimation in balance, thereby increasing transmission quality and throughput.
Claims17
A base station device comprising:
- a candidate selecting unit configured to select a candidate reference signal (RS) configuration based on a transmission environment associated with a user equipment (UE);
- and
- a configuration controller configured to apply the candidate RS configuration to at least one of slots to which a predetermined RS configuration for the UE is applied, and determine an optimal RS configuration between the predetermined RS configuration for the UE and the candidate RS configuration.
A user equipment (UE) device comprising:
- a configuration identifying unit configured to identify, from downlink control information (DCI) transferred from a base station for scheduling, a configuration for transmission of a reference signal (RS);
- and
- a controller configured to process the RS by applying the identified RS configuration in a case of a downlink and an uplink,
- wherein the RS configuration identified from the DCI is an optimal RS configuration determined by the base station with respect to each slot for the RS transmission to the UE device.
A reference signal (RS) configuration control method performed by a base station device, the method comprising:
- selecting a candidate RS configuration based on a transmission environment associated with a user equipment (UE);
- and
- performing a procedure of applying the candidate RS configuration to at least one of slots to which a predetermined RS configuration for the UE is applied, and determining an optimal RS configuration between the predetermined RS configuration for the UE and the candidate RS configuration.
A reference signal (RS) configuration control method performed by a user equipment (UE) device, the method comprising:
- identifying, from downlink control information (DCI) transferred from a base station for scheduling, a configuration for RS transmission;
- and
- controlling the RS by applying the identified RS configuration in a case of a downlink and an uplink,
- wherein an optimal RS configuration is determined by the base station with respect to each slot for the RS transmission to the UE device.
