Embodiment Construction

[0118] For purposes of illustration and not limitation, the following description is set forth in specific details, such as particular network environments, in order to provide a thorough understanding of the techniques disclosed herein. It will be apparent to those skilled in the art that the technology may be practiced in other embodiments than these specific details. Furthermore, although the following embodiments are primarily described for 5G Radio Access Technologies (RATs) such as 3GPP New Radio (NR) technologies, it is readily apparent that the techniques described herein may also be implemented in any other wireless communication network, These include Long Term Evolution (LTE), LTE-Advanced, Wireless Local Area Network (WLAN) according to standards series IEEE 802.11, Worldwide Interoperability for Microwave Access (WiMAX) according to standards series IEEE 802.16, ZigBee, Z-Wave or X10.

[0119] Furthermore, those skilled in the art will understand that the function...

Abstract

A technique for transmitting data (504) from a first station to a second station on a contention-based radio channel is described. As to a method aspect of the technique, the first station obtains a transmit identifier (506) for the first station from a set of transmit identifiers; transmits control information (502) including the transmit identifier (506) to the second station; and transmits thedata (504) to the second station according to the control information (502), wherein the data includes a station identifier (508) for the first station, the station identifier (508) or a combination of the station identifier and the transmit identifier (506) being indicative of the first station.

Description

technical field [0001] The present disclosure generally relates to techniques for communicating data over contention-based radio channels. More specifically, without limitation, methods and apparatus are provided for transmitting data from one station to another using a contention-based radio channel. Background technique [0002] For conventional cellular radio access technologies (RATs) such as Long Term Evolution (LTE) according to the 3rd Generation Partnership Project (3GPP), the base station (e.g. evolved Node B or eNB) defines the frame structure in the time domain and is responsible for passing Radio resources are allocated by transmitting downlink control information (DCI) to a wireless device (eg, user equipment or UE) in a radio resource control (RRC) connected state with an eNB. Each UE in RRC Connected state is assigned a Radio Network Temporary Identifier (RNTI) that the eNB and UE use in its communication. DCI contains scheduling grants for allocating uplink...
