Abstract
(EN) Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method comprises determining, at a first terminal device, a time window during which a second terminal device is to filter Sidelink Reference Signal Received Power (SL-RSRP) of sidelink transmissions received from the first terminal device; receiving, from the second terminal device, the filtered SL-RSRP during the time window; estimating a sidelink path loss based on the filtered SL-RSRP; and applying the sidelink path loss to power control of at least one subsequent sidelink transmission from the first terminal device to the second terminal device. In this way, the SL path loss can be estimated more accurately and reasonably, and thus the power control based on the the SL path loss can be performed more effectively.
(FR) Des modes de réalisation de la présente divulgation concernent des procédés, des dispositifs et un support lisible par ordinateur permettant une communication. Un procédé consiste à déterminer, au niveau d'un premier dispositif terminal, une fenêtre temporelle pendant laquelle un second dispositif terminal doit filtrer une puissance reçue de signal de référence de liaison latérale (SL-RSRP) associée à des transmissions de liaison latérale reçues en provenance du premier dispositif terminal; recevoir, en provenance du second dispositif terminal, la SL-RSRP filtrée pendant la fenêtre temporelle; estimer une perte de trajet de liaison latérale (SL) sur la base de la SL-RSRP filtrée; et appliquer la perte de trajet de liaison latérale à la commande de puissance d'une ou plusieurs transmissions de liaison latérale ultérieures en provenance du premier dispositif terminal et à destination du second dispositif terminal. De cette manière, la perte de trajet SL peut être estimée de manière plus précise et raisonnable, ce qui permet d'appliquer plus efficacement la commande de puissance sur la base de la perte de trajet SL.
