Title
(EN) RECEIVER FEEDBACK IN WIRELESS SYSTEMS
(FR) RÉTROACTION DE RÉCEPTEUR DANS DES SYSTÈMES SANS FIL
Abstract
(EN)
Systems, methods, and instrumentalities are disclosed for receiver feedback in wireless systems. Receiver feedback format, content, type and/or timing may be determined as a function of, for example, at least one of a type of soft-combining processing to apply in a HARQ process, a HARQ operating point for the HARQ process, one or more reference transmissions for controlling a type of HARQ feedback for the HARQ process, and a feedback suppression parameter for one or more transmissions in a sequence associated with the HARQ process or a transport block (TB). Uniform and non-uniform CB-to-CBG mapping may be provided (e.g., by a WTRU) based on, for example, one or more parameters, interference and channel conditions and/or a probability of or actual pre-empting transmissions. A CB to CBG mapping indication may be provided, for example, in support of selecting a CB to CBG mapping from multiple CB to CBG mappings. Intra- and inter-WTRU interference/preemption indications may be provided.

La présente invention concerne des systèmes, des procédés et des instruments pour une rétroaction de récepteur dans des systèmes sans fil. Un format, un contenu, un type et/ou une synchronisation de rétroaction de récepteur peuvent être déterminés en fonction, par exemple, d'un type de traitement de combinaison logicielle à appliquer dans un processus de HARQ et/ou d'un point de fonctionnement de HARQ pour le processus de HARQ et/ou d'une ou de plusieurs transmissions de référence pour commander un type de rétroaction de HARQ pour le processus de HARQ et/ou un paramètre de suppression de rétroaction pour une ou plusieurs transmissions dans une séquence associée au processus de HARQ ou dans un bloc de transport (TB). Un mappage CB à CBG uniforme et non uniforme peut être fourni (par exemple, par une WTRU) sur la base, par exemple, d'un ou de plusieurs paramètres, de conditions d'interférences et de canal et/ou d'une probabilité de transmissions de préemption ou de transmissions de préemption réelles. Une indication de mappage CB à CBG peut être fournie, par exemple, pour prendre en charge la sélection d'un mappage CB à CBG parmi de multiples mappages CB à CBG. Des indications d'interférence/préemption intra-WTRU et inter-WTRU peuvent être fournies.
