Problems solved by technology

[0006] However, existing access mechanisms rely on contention windows, which lead to the loss of radio resources in the time domain and increase the delay of radio communication
In addition, existing access mechanisms can still result in HNP if the radio communication includes directed radio transmissions directed at the receiving radio device
Therefore, HNP can occur even if the hidden node is a neighboring node of the transmitting radio device of the radio communication

Embodiment Construction

[0112] In the following description, for purposes of explanation and not limitation, specific details are set forth, such as a specific network environment, in order to provide a thorough understanding of the techniques disclosed herein. It will be apparent to those skilled in the art that the technique may be practiced in other embodiments that depart from these specific details. Furthermore, although the following embodiments are primarily described for New Radio (NR) or 5G implementations, it will be apparent that the techniques described herein can also be used in wireless local area networks (WLANs) according to the standard series IEEE 802.11 for networks including 3GPP LTE ( Implemented by any other radio communication technology such as LTE-Advanced or a related radio access technology such as MulteFire for Bluetooth (especially Bluetooth Low Energy, Bluetooth Mesh and Bluetooth Broadcasting) according to the Bluetooth Special Interest Group (SIG) ), for Z-Wave accordi...

Abstract

A technique for transmitting and receiving data (610) in a radio communication from a second radio device (200) to a first radio device (100) is described. As to a method aspect of the technique, oneor more radio resources (606) are determined based on radio signals (602) received atthe firstradio device(100). The one or more radio resources (606) comprise at least one spatial stream among different spatial streams receivable at the first radio device (100). A status message (604) indicative of the one or more determined radio resources (606) is transmitted to the second radio device (200).The data (610) from the second radio device (200) is received at the first radio device (100) on at least one radio resource depending on the one or more radio resources (606) indicated in the transmitted status message (604).

Description

technical field [0001] The present disclosure relates to device-to-device communication. More specifically and without limitation, methods and devices for allocating radio resources in direct communication between radio devices are provided. Background technique [0002] Radio communication for road traffic can proactively avoid accidents and improve traffic efficiency. To this end, vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), and vehicle-to-infrastructure (V2I) communications (collectively referred to as vehicle-to-everything (V2X) communications) require high reliability and low end-to-end (E2E) latency, This can be achieved by device-to-device (D2D) communication, ie direct communication, which involves packet transmission directly between radio devices participating in traffic. [0003] Since LTE Release 12, the 3rd Generation Partnership Project (3GPP) has extended the Long Term Evolution (LTE) platform by building V2X communication on Proximity Based Servic...
