ABORT BLIND MULTICAST CHANNEL (MCH) DECODING

A UE 1202 includes a reception component 1204, an eMBMS component 1206, a detection component 1212, a decoding determination component 1208, and a transmission component 1210. The UE determines a failure to receive a multicast channel scheduling information (MSI) for a first MCH scheduling period (MSP). In a certain configuration, an eNodeB 1250 transmits an MSI 1232 for a first MSP to the apparatus 1202. The eMBMS component 1206 determines a failure to receive the MSI 1232 for the first MSP. The eNodeB 1250 transmits one or more subframes 1234 to the apparatus 1202. The reception component 1204 may receive the subframes 1234 and send the subframes 1234 to the eMBMS component 1206. The eMBMS component 1206 attempts to decode one or more subframes 1234 in the first MSP. The detection component 1212 detects an occurrence of an MSP abort decoding event 1236 from the eMBMS component 1206. The detection component 1212 sends event information 1238 about the MSP abort decoding event 1236 to the decoding determination component 1208.The decoding determination component 1208 determines that the first MSP does not include any subframe 1234 that carries multimedia broadcast multicast service (MBMS) data of an MBMS segment based on the detection of the MSP abort decoding event 1236. Accordingly, the decoding determination component 1208 sends to the eMBMS component 1206 instruction 1240 that instructs the eMBMS component 1206 to abort the attempt to decode the one or more subframes 1234. Detecting an abort decoding event 1236 may include detecting: (a) that a failure to decode N subframes occurs, (b) that a signal strength of each subframe of the N subframes does not meet a threshold, (c) that the first MSP is in the MBMS segment and is subsequent to a final MSP that includes a subframe carrying MBMS data of the MBMS segment, or (d) that a first transmission mode used to transmit a first subframe matches a reference transmission mode. Selon l'invention, un équipement utilisateur (UE) (1202) comprend un composant de réception (1204), un composant eMBMS (1206), un composant de détection (1212), un composant de détermination de décodage (1208), et un composant d'émission (1210). L'UE détermine un échec de réception d'informations de planification de canal de multidiffusion (MSI) pour une première période de planification de MCH (MSP). Dans une certaine configuration, un nœud B évolué (eNodeB) (1250) envoie des MSI (1232) pour une première MSP à l'appareil (1202). Le comp
