Abstract
A technique for transmitting and receiving data from a node of a radio access network, RAN, to a radio device is described. The radio device is configured for discontinuous reception, DRX, according to a DRX configuration. As to a method aspect of the technique, it is determined whether data is available for transmission to the radio device. A power saving signal is selectively transmitted to the radio device depending on the DRX configuration. If the data is available, at least one of the data and a scheduling assignment for the transmission of the data is transmitted to the radio device on a radio resource according to the DRX configuration.
Claims19
A method of transmitting data from a node of a radio access network (RAN) to a radio device that is configured for discontinuous reception (DRX) according to a DRX configuration, the method comprising:
- indicating, via broadcasting system information, whether a wake-up signal (WUS) is to be transmitted in a selective transmission to the radio device;
- determining whether data is available for transmission to the radio device;
- selectively transmitting the WUS to the radio device depending on the DRX configuration and the indication via the system, wherein a length of the WUS depends on the maximum coupling loss (MCL) supported by the node;
- and
- transmitting, in response to the data being available and to the radio device on a radio resource according to the DRX configuration, data and/or a scheduling assignment for the transmission of the data.
A method of receiving data from a node of a radio access network (RAN) at a radio device that is configured for discontinuous reception (DRX) according to a DRX configuration, the method comprising:
- receiving an indication, via broadcasted system information, whether a wake-up signal (WUS) will be transmitted in a selective transmission to the radio device;
- selectively enabling, depending on the DRX configuration and the indication via the system information, a receiver for receiving the WUS from the node, wherein a length of the WUS depends on the maximum coupling loss (MCL) supported by the node;
- determining, based on the receiver enabled for receiving the WUS, whether data is available for reception from the node;
- and
- receiving, in response to the data being available and from the node on a radio resource according to the DRX configuration, the data and/or a scheduling assignment for the transmission of the data.
A device for transmitting data from a node of a radio access network (RAN) to a radio device that is configured for discontinuous reception (DRX) according to a DRX configuration, the device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the device is operative to:
- indicate, via broadcasting system information, whether a wake-up signal (WUS) is to be transmitted in a selective transmission to the radio device;
- determine whether data is available for transmission to the radio device;
- selectively transmit the WUS to the radio device depending on the DRX configuration and the indication via the system information, wherein a length of the WUS depends on the maximum coupling loss (MCL) supported by the node;
- and
- transmit, in response to the data being available and to the radio device on a radio resource according to the DRX configuration, the data and/or a scheduling assignment for the transmission of the data.
