Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with LTE based paging for peer discovery. In one example, an eNodeB is equipped to receive a message including a D2D discovery notification for a UE, determine that the UE is in an idle mode, and transmit a paging notification to the UE including the D2D discovery notification. In another example, a UE is equipped to receive, from an eNodeB, a paging notification including a D2D discovery notification, determine, while in idle mode, that the D2D discovery notification is successfully decoded, and transmit an ACK to the eNodeB using a RACH sequence on a PRACH.

Abstract: Methods and apparatus for making handoff decisions in an access terminal which can support both best effort and QoS traffic, e.g., when operating in a best effort and QoS mode of operation, respectively, are described. The access terminal receives an indicator indicating the fraction of communications resources not utilized for QoS service and information indicating a number of best effort users being supported by the attachment point. During QoS mode operation, connections to attachment points which can support the access terminal's minimal QoS requirements are identified and then from among the identified set, the attachment point which can provide a connect supporting the most best effort traffic from the access terminal is selected. In best effort mode operation the access terminal selects the attachment point connection which will provide the greatest amount of throughput to the access terminal for best effort traffic.

Abstract: A wireless terminal receives peer to peer resource control information from a base station. The peer to peer resource control information is used by the wireless terminal in a peer to peer network to control transmission scheduling and/or resource utilization. The base station sends the control signals at a first rate which is slower than the rate at which wireless terminals make transmission decisions for traffic slots. During the intervals between receipt of the base station control signals, wireless terminals make transmission decisions with regard to multiple traffic segments. The decisions are also influenced based on peer to peer signaling occurring between the wireless terminals in the network for each traffic slot. Resource utilization feedback information is provided from the wireless terminal to the base station. Based on the feedback information the base station updates the resource utilization control information and sends updated resource utilization control signals to the wireless terminals.
