    摘要： Methods and apparatus are provided to enable aperiodic sounding reference signaling including frequency hopping through the use of additional RRC configuration. The methods can require little or no additional L1 overhead to support narrowband frequency hopping for aperiodic sounding transmissions. In some embodiments, an approach is provided for extending an LTE periodic sounding reference signal methodology to include aperiodic sounding. One benefit of the proposed technique is that it enables each UE to perform aperiodic channel sounding in sounding subframes, using a frequency-hopping pattern, in which the sounding bandwidth of the UE can be narrowed appropriately to match its link capability. Additional benefits of the new approach include better resource utilization, lower signaling overhead, faster channel information update rates, and lower blocking probabilities.

    摘要： A system and method for implementing call handover (HO) is disclosed. A user equipment (UE) may be configured to communicate with a wireless communication network. The UE is configured to transmit a measurement report to at least one of a serving cell and at least one cell of a coordinated multi-point (CoMP) cell set. The UE is configured to listen for an HO command from a serving cell. The HO command identifies a target cell. The UE is configured to detect a radio link failure between the UE and the serving cell, listen for an HO command from a first cell in the CoMP cell set for a first time duration, and, when an HO command is received from the first cell in the CoMP cell set within the first time duration, perform handover to the target cell identified in the HO command.

The UE is configured to transmit a measurement report to at least one of a serving cell and at least one cell of a coordinated multi-point (CoMP) cell set. The UE is also configured to listen for control channel transmissions from at least one of the serving cell and a first cell in the CoMP cell set, receive a resource allocation from at least one of the serving cell and the first cell in the CoMP cell set, and receive an HO command jointly from the serving cell and the first cell in the CoMP cell set. The HO command identifies a target cell. The UE is also configured to perform handover to the target cell identified in the HO command.

    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.
