Title (EN) SHORT CONTROL CHANNEL ELEMENT (SCCE) TO SHORT RESOURCE ELEMENT GROUPS (SREG) MAPPING FOR SHORT PHYSICAL DOWNLINK CONTROL CHANNEL (SPDCCH)
(FR) MAPPAGE D'ÉLÉMENTS DE CANAL DE COMMANDE COURT (SCCE) SUR DES GROUPES D'ÉLÉMENTS DE RESSOURCES COURTS (SREG) POUR UN CANAL DE COMMANDE DE LIAISON DESCENDANTE PHYSIQUE COURT (SPDCCH)
Abstract:
(EN) Short Control Channel Elements (SCCE) to Short Resource Element Groups (SREG) mapping for Short Physical Downlink Control Channel (SPDCCH) is provided. A User Equipment (UE) receives a communication from a base station; determines a mapping between one or more SCCE and corresponding SREG; and processes the communication based on the mapping. A base station determines a mapping between one or more SCCE and corresponding SREG for a communication to a UE and transmits a communication to the UE based on the mapping. In this way, the localized and distributed SCCE to SREG mapping for CRS-based SPDCCH is defined. Also, the SCCE to SREG mapping for 2 and 3 OFDM symbols DMRS-based SPDCCH is defined. For DMRS-based SPDCCH, a distributed configuration at SCCE level is defined. This may improve latency and can improve the average throughput of a communications system. Radio resource efficiency could be positively impacted by latency reductions.
(FR) L'invention concerne le mappage d'éléments de canal de commande court (SCCE) sur des groupes d'éléments de ressources courts (SREG) pour un canal de commande de liaison descendante physique court (SPDCCH). Un équipement d'utilisateur (UE) reçoit une communication, d'une station de base; détermine un mappage entre un ou plusieurs SCCE et un SREG correspondant; et traite la communication sur la base du mappage. Une station de base détermine un mappage entre un ou plusieurs SCCE et un SREG correspondant pour une communication à un UE et transmet une communication à l'UE sur la base du mappage. De cette manière, le mappage SCCE sur SREG localisé et distribué pour un SPDCCH basé CRS est défini. De plus, le mappage SCCE sur SREG pour un SPDCCH basé DMRS à 2 et 3 symboles OFDM est défini. Pour un SPDCCH basé DMRS, une configuration distribuée au niveau SCCE est définie. Cela peut améliorer la latence et le débit moyen d'un système de communications. L'efficacité des ressources radio peut être impactée positivement par des réductions de latence.
