摘要： Certain aspects of the present disclosure provide techniques and apparatus for startup and recovery of a radio link between a relay node and a donor base station. According to certain aspects, a relay node may perform a random access procedure utilizing a random access channel (RACH) to transition between Uu interface operations and Un interface operations. According to certain aspects, the relay node may perform radio link failure (RLF) recovery utilizing RACH procedures for a Un interface. The procedures described herein, according to certain aspects, may utilize a dedicated relay RACH resource and a Relay Physical Downlink Control Channel (R-PDCCH).

摘要： Systems, methods and apparatus for facilitating handover control using resource reservation with frequency reuse are provided. In one embodiment, the method can include: transmitting scheduling information for the transmission of information on frequencies corresponding to an unreserved portion of a frequency band. The method can also include transmitting scheduling information for the transmission of information on frequencies corresponding to a reserved portion of the frequency band. A frequency reuse scheme can be employed over the frequencies corresponding to the reserved portion of the frequency band, and the information transmitted on the frequencies corresponding to the reserved portion of the frequency band can be handover signalling information.

摘要： The number of handover-related failures that occur in a communication system may be reduced by taking target access point conditions into account when declaring radio link failure and/or by delaying certain handover operations. In some aspects, criteria for radio link failure detection and access terminal-controlled mobility may take into account access point parameters related to neighboring cells that may be available as mobility targets. For example, filtering mechanisms for detecting radio link failure based on radio layer problem reports may also take into account the availability of various neighbor access points and their measured signal strengths. In addition, a handover command may be sent earlier than in conventional systems (e.g., the handover command may be sent even though the target access point is weaker than the source access point) and include an indication that instructs the access terminal to delay handover until a specified condition is met. For example, handover may be delayed until the target access point becomes stronger than the source access point.

摘要： Apparatus and methods for determining a location estimate of a mobile device based on an extended set of assistance data are presented.

By seeding the mobile device with assistance data expected to be useful in the future, the network reduces messaging between the network and mobile device and battery consumption by the mobile device.

摘要： Systems and methodologies are described herein that facilitate efficient packet differentiation and forwarding in a wireless communication system. As described herein, identifiers or tags (e.g., corresponding to radio bearers, logical channels, Internet Protocol (IP) addresses, etc.) can be applied to respective packets based on their destinations as determined by traffic flow templates (TFTs) associated with the packets. Further, techniques are provided for establishing radio bearers, IP addresses, and/or other resources for transmission of packets associated with respective TFTs in a manner irrespective of associated quality of service (QoS) policies for the TFTs. Upon an establishment of resources, techniques are described herein for tagging packets with resources associated with TFTs corresponding to the packets to facilitate forwarding of respective packets to their intended destinations with lowered required processing cost. Additionally, techniques are described herein for offloading packet analysis and/or forwarding functionality from a terminal to a device tethered to the terminal.
