    摘要： A method of dynamic resource transaction in wireless OFDMA systems is proposed. In macro-femto overlay network architecture, network and traffic condition varies dynamically. Dynamic resource transaction is a powerful mechanism to achieve effective interference mitigation and flexible radio resource management to enhance resource utilization as well as to improve link performance. Dynamic resource transaction can be performed by signaling or message exchange through backhaul network or air-interface connections. The signal or message through backhaul network can be directly exchanged among multiple base stations or be routed through a centralized self-organizing network (SON) server. In one embodiment, dynamic resource transaction is used to achieve adaptive reservation region configuration, a solution to avoid interference and frequent handover for highspeed mobile stations.

    摘要： Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.

    摘要： An adaptive RACH operation is proposed for machine-type communications (MTC) in a 3GPP wireless network. The adaptive RACH operation is based on context information to reduce RACH collision probability, to control network overload, and to enhance system performance. The context information includes device related information and network related information. Device related information includes device type and service or application type. Network related information includes network load information and historical statistics information. Based on the context information, an MTC device adjusts various network access and RACH parameters by applying adaptive RACH operation in different levels. For example, in the application level and the network level, the MTC device adjusts its access probability or RACH backoff time for RACH access. In the radio access network (RAN) level, the MTC device adjusts its access probability or RACH backoff time, or transmits RACH preambles using adjusted RACH radio resources and preambles.
