Abstract
An approach for providing interference measurements for device-to-device communication is disclosed. A logic generates a control signal to instruct a plurality of stations to perform measurement relating to interference or path loss by the stations. The logic then receives measurement information from the stations and determines, based on the measurement information, whether resources are to be scheduled to provide direct communication between two of the stations.
Claims17
A method comprising:
- generating at a base station a control signal to instruct a plurality of user devices to perform measurement relating to interference or path loss between the user devices;
- receiving at the base station measurement information from the user devices, wherein the measurement information includes power information;
- classifying at the base station the measurement information from the user devices based on the power information;
- and
- determining at the base station, based on the measurement information, a classification of the resources for a device to device (D2D) communication between user devices, wherein the resources are to be scheduled to provide direct communication D2D via a direct wireless connection between two of the user devices;
- and when the base station determines measurement information is not available from either of the user devices, the base station may instruct the user devices with no measurement information to use a dedicated resource to establish a D2D connection.
3 more elements
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
- generate a control signal to instruct a plurality of user devices to perform measurement relating to interference or path loss between the user devices,
- receive measurement information from the user devices, wherein the measurement information includes power information;
- classify the measurement information from the user devices based on the power information;
- and
- determine, based on the measurement information, a classification of the resources for a device to device (D2D) communication between user devices, wherein resources are to be scheduled to provide direct communication via a direct wireless connection between two of the user devices;
- and when the apparatus determines measurement information is not available from either of the user devices, the apparatus may instruct the user devices with no measurement information to use a dedicated resource to establish a D2D connection.
7 more elements
A method comprising:
- receiving at a user device a control signal from a base station;
- performing at the user device measurement of interference or path loss in response to the control signal;
- initiating transmission of measurement information from the user device to the base station, wherein the measurement information includes power information;
- and
- receiving at the user device a resource allocation message specifying whether resources can be utilized to establish direct communication via a direct wireless connection from the user device to another user device, wherein whether the resources are to be scheduled to provide the direct communication is determined, based on the measurement information and a classification of the resources for a device to device (D2D) communication between user devices;
- classifying the measurement information that is based on the power information;
- and when the base station determines measurement information is not available from either of the user devices, the base station may instruct the user devices with no measurement information to use a dedicated resource to establish a D2D connection.
