Abstract
(EN)
A device uses a first protocol to incorporate a reservation of a medium using a second protocol within the bounds of the first protocol. For example, an evolved node B (also known as an e node B or eNB) using a long term evolution over unlicensed spectrum (LTE-U) protocol can be configured to reserve unlicensed spectrum using a (wireless local area network) WLAN message placed within a muting gap within the LAA protocol. In one embodiment, the eNB selects to broadcast the WLAN reservation message using a set of options including: (1) from a control channel region of LAA, (2) from a muting gap indicated by a reservation muting symbol pattern indicator, (3) from a time division duplex (TDD) guard period (GP), (4) from a TDD uplink pilot time slot (UpPTS), (5) from an empty uplink (UL) subframe or (6) from a sounding reference signal (SRS).

Un dispositif utilise un premier protocole pour incorporer une réservation d'un support en utilisant un second protocole dans les limites du premier protocole. Par exemple, un noeud B évolué (également connu en tant qu'eNodeB ou eNB) utilisant un protocole LTE -U (Long Term Evolution over Unlicensed Spectrum) peut être configuré pour réserver un spectre sans licence en utilisant un message de WLAN (réseau local sans fil) placé dans un espace de silence dans le protocole LAA. Dans un mode de réalisation, l'eNB sélectionne de diffuser le message de réservation de WLAN en utilisant un ensemble d'options comprenant : (1) à partir d'une région de canal de commande de LAA, (2) à partir d'un espace de silence indiqué par un indicateur de motif de symboles de silence de réservation, (3) à partir d'une période de garde (GP) de duplex en répartition dans le temps (TDD), (4) à partir d'une tranche de temps pilote de liaison montante TDD (UpPTS), (5) à partir d'une sous-trame de liaison montante (UL) vide ou (6) à partir d'un signal de référence de sondage (SRS)
