Abstract

A circuit arrangement includes a preprocessing circuit configured to obtain context information related to a user location, a learning circuit configured to determine a predicted user movement based on context information related to a user location to obtain a predicted route and to determine predicted radio conditions along the predicted route, and a decision circuit configured to, based on the predicted radio conditions, identify one or more first areas expected to have a first type of radio conditions and one or more second areas expected to have a second type of radio conditions different from the first type of radio conditions and to control radio activity while traveling on the predicted route according to the one or more first areas and the one or more second areas.

First claim

The invention claimed is:

1. A communication device comprising:
one or more processors configured to:
before receiving a first radio channel information, receive, from a proximate terminal device via a direct device-to-device (D2D) link, a device knowledge history class comprising classifications based on one or more of a device mobility or a network connection information for a geographic range;

request a first radio channel information from the proximate terminal device based on the device knowledge history class, wherein the first radio channel characterizes a radio downlink channel for a network access node that the communication device and the proximate terminal device are connected to:
receive the first radio channel information;
determine a second radio channel information for the radio downlink channel based on downlink signals received from the network access node;
combine the first radio channel information and the second radio channel information to obtain a joint radio channel information for the radio downlink channel; and
receive downlink data from the network access node based on the joint radio channel information;
wherein the combining of the first radio channel information and the second radio channel information to obtain the joint radio channel information for the radio downlink channel comprises determining a joint channel state information estimation using the first radio channel information and the second radio channel information based on respective times at which they were obtained.

2. The communication device of claim 1 , wherein the first radio channel information and the second radio channel information comprise a parameter to determine a channel estimation for the radio downlink channel.

3. The communication device of claim 1 , wherein the device knowledge history class indicates a geographic range for which the proximate terminal device has radio channel information.

4. The communication device of claim 1 , wherein the device knowledge history class indicates a quantity of radio access technologies for which the proximate terminal device has radio channel information.

5. The communication device of claim 1 , include wherein the device knowledge history class indicates whether the proximate terminal device has radio channel information for a concentrated geographic area.

6. A communication device comprising:
one or more processors configured to:
before receiving a first radio channel information, receive, from a proximate terminal device via a direct device-to-device (D2D) link, a device knowledge history class of the proximate terminal device, the device knowledge history class comprising classifications based on one or more of a device mobility or a network connection information for a geographic range;

request the first radio channel information from the proximate terminal device based on the device knowledge history class, wherein the first radio channel characterizes a radio downlink channel for a network access node that the communication device and the proximate terminal device are connected to:
receive, from the proximate terminal device vis the D2D link, the first radio channel information that characterizes a radio downlink channel for a network access node that the communication device is connected to;
determine a second radio channel information for the radio downlink channel based on downlink signals received from the network access node;
combine the first radio channel information and the second radio channel information to obtain a joint radio channel information for the radio downlink channel; and
receive downlink data from the network access node based on the joint radio channel information.

7. The communication device of claim 6 , wherein:
the device knowledge history class comprises classifications based on one or more of a device mobility or a network connection information for a geographic range; and
the device knowledge history class indicates the proximate terminal device is classified as at least one of local knowledge class-heterogeneous, local knowledge-homogeneous, wide spread knowledge-heterogeneous, wide spread knowledge-homogenous, wide spread knowledge with some hotspots-heterogeneous, and wide spread knowledge with some hotspots-homogeneous.

8. The communication device of claim 6 , wherein the one or more processors are further configured to transmit the second radio channel information to the proximate terminal device on the direct D2D link.
