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.

摘要： A method of system information (SI) acquisition with reduced signaling overhead is proposed. To reduce SI broadcast overhead, the quantity of periodic SI broadcast and the frequency of on-demand SI acquisition need to be reduced. In order to reduce the quantity of periodic SI broadcasting, on-demand SI delivery is enabled. With on-demand SI delivery, signaling overhead is proportional to the frequency of SI acquisition. From the network side, the base stations proactively provide SI delivery options and delivers SI over unicast or scheduled broadcast. From the UE side, UE determines how to acquire SI, i.e., by listening to broadcast or by sending an on-demand request via existing procedures such as a random-access procedure over a random-access channel (RACH).

摘要： Methods are provided to support path selection for a remote UE configured with multipath in a UE-to-network relay. A direct path or an indirect path is set as the primary path. Side information of the indirect path is considered for path selection. A remote UE can select a suitable path by utilizing the side information for path selection to check whether an indirect path can fulfill the QoS requirement of arriving UL traffic. In a network-controlled path selection, the base station can request UE to send side information. The base station indicates the selected path or the change of primary path to the UE via explicit signaling. Each path is identified by a path ID. The path indication is in a granularity of per radio bearer, per QoS flow, per logical channel, or per logical channel group.

摘要： Various solutions for data transmission over multiple uplink carrier with respect to user equipment (UE) in mobile communications are described. A UE may establish a connection over a downlink component carrier and a first uplink component carrier with a network apparatus. The UE may further establish a connection over a second uplink component carrier with the network apparatus. The UE may transmit uplink data to the network apparatus via at least one of the first uplink component carrier and the second uplink component carrier. The UE may also assign the first uplink component carrier as a primary carrier and assigning the second uplink component carrier as a supplementary carrier. The UE may further switch the primary carrier from the first uplink component carrier to the second uplink component carrier.
