Problems solved by technology

This unpredictability can make the applicability of SPS or any other delay-aware scheduler to V2X traffic inefficient, as periodic resources need to be provisioned in a conservative manner to ensure minimum QoS requirements are met

Embodiment Construction

[0048] The following techniques and apparatus are described in the context of V2X communications, and in some cases may be described using terminology specific to the LTE standard. It should be understood, however, that the disclosed embodiments may be applied to any service having similar characteristics, and / or to other wireless systems. The service can be provided over a cellular link or a direct link such as a side link or a D2D link.

[0049] The specific embodiments discussed here provide particular advantages for services with some periodic component, such as CAM services for ITS, with a maximum frequency generation of 10 Hz and packets typically between 190-300 bytes . However, these techniques can be used more generally.

[0050] Conventional cellular SPS (semi-persistent scheduling) includes a first configuration step in which parameters for periodic resource allocation are signaled from the eNB to the UEs involved. This is followed by an activation / deactivation s...

Abstract

In one aspect, a wireless device receives from a wireless network node two or more semi-persistently scheduled SPS configurations, each of the SPS configurations defining a plurality of periodic transmission opportunities for the wireless device, the two or more SPS configurations At least two of the plurality of SPS configurations have different periods for periodic transmission opportunities. Then, the wireless device sends data corresponding to the first service type or first radio bearer according to the first SPS configuration of the two or more SPS configurations, and sends data corresponding to the first service type or the first radio bearer according to the second SPS configuration of the two or more SPS configurations The SPS configuration sends data corresponding to the second service type or the second radio bearer.

Description

technical field [0001] The present disclosure relates generally to wireless communication networks, and more particularly to resource management in networks with side-link operation, such as between vehicles. This technique can be applied to semi-persistent scheduling between two nodes (more generally, including between wireless devices and wireless network nodes or other wireless devices). Background technique [0002] The 3rd Generation Partnership (3GPP) is responsible for developing and maintaining specifications for the fourth generation of wireless systems commonly referred to as "Long Term Evolution" or LTE, and more formally as Evolved Universal Terrestrial Radio Access (E-UTRA) or Evolved Universal Terrestrial Radio Access Network (E-UTRAN). During the development of the Release 12 version of these specifications, the LTE standard was expanded to include features to support device-to-device (D2D) communications, both for commercial and public safety applications. ...
