    摘要： The present disclosure relates generally to systems and methods for timing synchronization. Uplink synchronization is a necessary component of a UE 110 operating in a mobile, wireless network. Reliable uplink synchronization generally requires regular uplink transmission containing reference signals. A method is provided that defines a burst period 603 for sending the reference signals, determines an interval 605 between the reference signals, and sends a timing instruction message 607 that includes the burst period and the determined interval. A second method is provided that receives the timing instruction message and sends the reference signals in accordance with the timing instruction.

    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.

    摘要： A method and system for efficient DRX operation during handover in LTE_ACTIVE in which a user equipment expects handover to occur, the method having the steps of: checking (114,314) whether a no handover initiation decision is received within a predetermined time period; if no, performing the steps of: ensuring (118,320) the user equipment is not in a DRX sleep period during reception of a handover grant; checking (120,322) whether a handover grant is received, and if yes, performing (122,330) a handover procedure; and if no, resuming (125,340) a DRX sleep interval; and if yes, ending (116,316) the process.

    摘要： Methods of combining semi-persistent resource allocation and dynamic resource allocation are provided. Packets, such as VoIP packets, are transmitted on the uplink and downlink using respective semi-persistent resources. For each mobile device, awake periods and sleep periods are defined. The semi-persistent resources are aligned with the awake periods so that most of the time the mobile device can turn off its wireless access radio during the sleep periods. In addition, signalling to request, and to allocate, resources for additional packets are transmitted during the awake periods, and the resources allocated for the additional packets are within the awake windows.
