摘要： The present disclosure is directed to a system and method for operating a user agent (UA) and access device located within a communications cell according to a half-duplex (HD), frequency-division duplexing (FDD) protocol. The system and method are designed to accommodate a guard period (GP) between downlink (DL) and uplink (UL) communications from the UA, while addressing the loss of at least part of the DL communication before a subsequent UL subframe to accommodate the GP.

摘要： A method for preventing a relay node from missing a transmission from an access node. The method includes, when a ten millisecond periodicity is used for Multicast/Broadcast Single Frequency Network (MBSFN) subframes, setting a time between an uplink grant from the access node to the relay node and an acknowledgement/negative-acknowledgement message (ACK/NACK) from the access node to the relay node equal to ten milliseconds. The method further includes, when a forty millisecond periodicity is used for MBSFN subframes, the access node sending the relay node an asynchronous grant for an uplink retransmission when a data packet is missed, and when the relay node receives the grant for the uplink retransmission, the relay node retransmitting the missed data packet.
