Abstract
Techniques are provided to ensure that a terminal device is able to perform measurements efficiently when an on/off scheme is used by network nodes, particularly in a heterogeneous network environment. An example method, implemented in a network node, comprises obtaining a discovery signal window pattern, the discovery signal window pattern defining one or more discovery signal windows during which each of a plurality of cells is to transmit a corresponding discovery signal, and sending an indication of the discovery signal window pattern to a terminal device.
Claims14
A method, in a base station, comprising:
- sending a configuration of one or more measurement gaps to a user equipment;
- sending a configuration of a discovery signal window pattern to the user equipment, the discovery signal window pattern defining one or more discovery signal windows during which each of a plurality of cells is to transmit a corresponding discovery signal.
A method, in a user equipment, comprising:
- receiving a configuration of one or more measurement gaps from a base station;
- performing one or more measurements for one or more of the plurality of cells during one or more discovery signal windows in accordance with the one or more measurement gaps, the discovery signal windows being intervals during which each of a plurality of cells is to transmit a corresponding discovery signal, as defined by a discovery signal window pattern.
A base station comprising a communications interface circuit and a processing circuit, wherein the processing circuit is configured to:
- send a configuration of one or more measurement gaps to a user equipment;
- send a configuration of the discovery signal window pattern to the user equipment, the discovery signal window pattern defining one or more discovery signal windows during which each of a plurality of cells is to transmit a corresponding discovery signal.
A user equipment comprising a transceiver circuit and a processing circuit, wherein the processing circuit is configured to:
- receive a configuration of one or more measurement gaps from a base station;
- perform one or more measurements for one or more of the plurality of cells during one or more discovery signal windows in accordance with the one or more measurement gaps, the discovery signal windows being intervals during which each of a plurality of cells is to transmit a corresponding discovery signal, as defined by a discovery signal window pattern.
