Abstract

A method in a first wireless device is disclosed. The method comprises obtaining first side information for a node, the first side information comprising information about a resource allocation scheme used by the node, and determining, based at least in part on the first side information, one or more characteristics of the resource allocation scheme used by the node. The method further comprises adapting a transmitter behavior of the first wireless device based on the determined one or more characteristics of the resource allocation scheme used by the node.

First claim

1 . A method in a first wireless device, comprising:
obtaining first side information for a node, the first side information comprising information about a resource allocation scheme used by the node; determining, based at least in part on the first side information, one or more characteristics of the resource allocation scheme used by the node; and adapting a transmitter behavior of the first wireless device based on the determined one or more characteristics of the resource allocation scheme used by the node.

2 . The method of claim 1 , wherein:
determining, based at least in part on the first side information, one or more characteristics of the resource allocation scheme used by the node comprises determining that one or more resources used by the node were scheduled by a network node using centralized resource allocation; and adapting the transmitter behavior of the first wireless device based on the determined one or more characteristics of the resource allocation scheme used by the node comprises avoiding transmitting on resources that would interfere with one or more resources scheduled by the network node using centralized resource allocation.

3 . The method of claim 1 , wherein determining, based at least in part on the first side information, one or more characteristics of the resource allocation scheme used by the node comprises predicting, based at least in part on the first side information, the resources to be used by the node at a future time instance.

4 . The method of claim 1 , wherein adapting a transmitter behavior of the first wireless device based on the determined one or more characteristics of the resource allocation scheme used by the node comprises one or more of:
avoiding transmitting on resources that would interfere with one or more resources of the resource allocation scheme used by the node; selecting one or more resource patterns that are compatible with the resource allocation scheme used by the node; and selecting a resource allocation scheme that is compatible with the resource allocation scheme used by the node.

5 . The method of claim 1 , wherein:
determining, based at least in part on the first side information, one or more characteristics of the resource allocation scheme used by the node comprises determining that the node uses a random resource allocation scheme; and adapting the transmitter behavior of the first wireless device based on the determined one or more characteristics of the resource allocation scheme used by the node comprises transmitting using one or more resources without attempting to avoid transmitting on resources that would interfere with one or more resources of the resource allocation scheme used by the node.

6 . The method of claim 1 , wherein the first side information comprises one or more of:
an indication that one or more resources used by the node were scheduled by a network node using centralized resource allocation; an indication of a resource allocation algorithm used by the node; an indication of a resource pattern used by the node; an indication that the node uses one of a pre-defined set of resource patterns; and an indication of one or more resources to be used by the node for a subsequent transmission at a future time instance.

7 . The method of claim 1 , further comprising:
transmitting second side information to at least a second wireless device, the second side information comprising information about a resource allocation scheme used by the first wireless device.

8 . The method of claim 1 , wherein the node comprises another wireless device or a network node.

9 . The method of claim 8 , wherein the first wireless device comprises a vehicular device engaged in device-to-device communication.

10 . The method of claim 1 , wherein:
the node comprises a network node; and the first side information comprising information about the resource allocation scheme used by the node comprises information about one or more resource allocations scheduled by the network node for one or more wireless devices.

11 . The method of claim 1 , wherein obtaining first side information for a node comprises one or more of:
receiving first side information from the node; obtaining first side information based on a resource mapping; and determining first side information based on one or more predefined configurations.

12 . A method in a node, comprising:
determining resource allocation scheme used by the node; generating first side information, the first side information comprising information about the resource allocation scheme used by the node; and transmitting the first side information to at least a first wireless device.

13 . The method of claim 12 , wherein transmitting the first side information to at least the first wireless device comprises transmitting the first side information to at least the first wireless device as part of a control message.

14 . The method of claim 12 , further comprising:
receiving second side information from a second wireless device, the second side information comprising information about a resource allocation scheme used by the second wireless device, wherein the second wireless device is one of the same wireless device as the first wireless device or a different wireless device; determining, based at least in part on the second side information, one or more characteristics of the resource allocation scheme used by the second wireless device; and adapting a transmitter behavior of the node based on the determined one or more characteristics of the resource allocation scheme used by the second wireless device.

15 . The method of claim 12 , wherein the first side information comprises one or more of:
an indication that one or more resources used by the node were scheduled by a network node using centralized resource allocation; an indication of a resource allocation algorithm used by the node; an indication of a resource pattern used by the node; an indication that the node uses one of a pre-defined set of resource patterns; and an indication of one or more resources to be used by the node for a subsequent transmission at a future time instance.

16 . The method of claim 12 , wherein the node comprises another wireless device or a network node.

17 . The method of claim 16 , wherein the node comprises another wireless device engaged in device-to-device communication.

18 . The method of claim 12 , wherein:
the node comprises a network node; and the first side information comprising information about the resource allocation scheme used by the node comprises information about one or more resource allocations scheduled by the network node for one or more wireless devices

19 . A first wireless device, comprising:
one or more processors, the one or more processors configured to: obtain first side information for a node, the first side information comprising information about a resource allocation scheme used by the node; determine, based at least in part on the first side information, one or more characteristics of the resource allocation scheme used by the node; and adapt a transmitter behavior of the first wireless device 41 - 04 based on the determined one or more characteristics of the resource allocation scheme used by the node.

20 . The first wireless device of claim 19 , wherein:
the one or more processors configured to determine, based at least in part on the first side information, one or more characteristics of the resource allocation scheme use
