Embodiment Construction

[0075] The following description presents various embodiments of the disclosed subject matter. These embodiments are given as teaching examples and should not be construed as limiting the scope of the disclosed subject matter. For example, certain details of the described embodiments may be modified, omitted, or expanded without departing from the scope of the disclosed subject matter. Furthermore, the described features can be combined with each other in any reasonable way.

[0076] speak first, listen later

[0077] Certain embodiments relate to LAT, which may lead to superior performance compared to LBT in certain contexts. In the following description, the term "source node" (SN) will refer to the device (e.g., UE or base station) that attempts to send information using LAT or LBT, and the term "destination node" (DN) will refer to the device to which the SN attempts to send information. sending device.

[0078] Unlike typical omnidirectional transmit and receive anten...

Abstract

Methods and apparatuses are provided for controlling a listen-after-talk (LAT) procedure in a wireless communication network comprising at least a source node (SN) and a destination node (DN). Such methods or apparatuses may obtain information indicating an operational context of the LAT procedure, adapt at least one parameter of the LAT procedure according to the obtained information, and controlat least the SN or the DN to communicate according to the LAT procedure having the adapted at least one parameter.

Description

technical field [0001] The disclosed subject matter generally relates to the field of telecommunications. Certain embodiments relate inter alia to concepts such as listen before talk (LBT), talk before listen (LAT), reconfiguration and adaptation, medium access, contention based access, parameter selection, and radio resource optimization. Background technique [0002] Mobile broadband will continue to drive the need for high overall traffic capacity and high achievable end-user data rates in radio access networks. Several future use cases and deployment scenarios will require data rates up to 10Gbps. These demands for very high system capacity and very high end-user data rates can be met by networks where the distance between access nodes ranges from a few meters in indoor deployments to about 50 meters in outdoor deployments, i.e., where the infrastructure The density is much higher than today's densest network. [0003] The wide transmission bandwidth required to deliv...
