Title
(EN) METHODS FOR PROVIDING LOWER-LAYER SPLIT FULL SPATIAL SAMPLES
(FR) PROCÉDÉS DE FOURNITURE D'ÉCHANTILLONS SPATIAUX COMPLETS DIVISÉS DE COUCHE INFÉRIEURE
Abstract
(EN)
Method, devices and systems for operating a radio unit, RU, in a network node of a wireless communication system are provided. Operations of such methods include receiving a request from a lower-layer split central unit, LLS-CU. The request includes an indication regarding multiple identified channels for receiving the spatial information for determining a direction to a user equipment. Operations include providing, in the RU, a spatial information receiver that is configured to represent multiple spatial beam directions and/or receive paths responsive to the request from the LLS-CU. Operations include receiving, into the spatial information receiver and via multiple radio branches that correspond to multiple antennas, beam signal information corresponding to multiple ones of the antennas.

L'invention concerne un procédé, des dispositifs et des systèmes pour faire fonctionner une unité radio, RU, dans un nœud de réseau d'un système de communication sans fil. Les opérations de ces procédés comprennent la réception d'une demande provenant d'une unité centrale divisée de couche inférieure, LLS-CU. La demande comprend une indication concernant de multiples canaux identifiés pour recevoir des informations spatiales pour déterminer une direction vers un équipement utilisateur. Les opérations comprennent la fourniture, dans la RU, d'un récepteur d'informations spatiales qui est configuré pour représenter de multiples directions de faisceau spatial et/ou recevoir des trajets en réponse à la demande provenant de la LLS-CU. Les opérations comprennent la réception, dans le récepteur d'informations spatiales et par l'intermédiaire de multiples branches radio qui correspondent à de multiples antennes, d'informations de signal de faisceau correspondant à de multiples antennes parmi les antennes.
