Embodiment Construction

[0039] As mentioned above, there is a need for an improved resource allocation scheme that provides a higher degree of space reuse. A higher degree of space reuse can advantageously allow unused resources to be redeployed for other applications. This disclosure contemplates various embodiments that can address resource allocation and the need to increase space reuse. For example, in some embodiments, a network node may allocate a pool of radio resources for V2x communication of multiple wireless devices. The network node may divide the radio resource pool allocated for V2x communication into multiple orthogonal radio resource sets. Each set of radio resources may have an associated set identifier. Collection identifiers can be positive integers. The network node may assign one or more sets of radio resources to each of the plurality of wireless devices based at least in part on the radio compatibility characteristic, and communicate the assigned set of radio resources to ea...

Abstract

A method in a network node (115) is disclosed. The method includes allocating (1204) a pool of radio resources for vehicle-to-other (V2x) communications of a plurality of wireless devices (110), and dividing (1208) the pool of radio resources allocated for V2x communications into a plurality of orthogonal sets of radio resources , each radio resource set has an associated set identifier comprising one of a plurality of positive integers. The method also includes assigning (1212) one or more sets of radio resources to each of the plurality of wireless devices based at least in part on the radio compatibility characteristic, and communicating (1216) the assigned set of radio resources to each wireless device for use.

Description

technical field [0001] The present disclosure relates generally to wireless communications, and more particularly to stepwise resource allocation for vehicular communications. Background technique [0002] During Release 12, the LTE standard has been extended to support device-to-device (D2D) (designated "sidelink") functionality for both commercial and public safety applications. An example application enabled by Rel-12 LTE is device discovery, where a device is able to sense the proximity of another device and associated application by broadcasting and detecting discovery messages carrying device and application identities. Another example application is direct communication based on physical channels directly terminated between devices. [0003] One of the potential extensions of device-to-device work includes support for vehicle-to-everything (V2x) communications, which includes any combination of direct communications between vehicles, pedestrians, and infrastructure. ...
