Abstract: Systems and methodologies are described that facilitate network management and optimization. As described herein, a network and a device communicating with the network can exchange network management information, thereby supporting a Self Organized Network (SON) architecture for improved network management and optimization performance. A Non-Access Stratum (NAS) layer protocol and/or an Internet Protocol (IP) application, in combination with a set of associated network management messages, can be utilized to exchange network management information between a device and a network. As further described herein, various procedures can be utilized to install a SON policy to a device in order to define device behavior for operations such as collecting and reporting information related to network management. Additionally, a set of standardized events can be defined, based on which a device can detect the occurrence of an event and report the occurrence to an associated network.

Abstract: System(s) and method(s) are provided for handover of a mobile terminal in a wireless communication system. Handoff resolution relies on both a downlink channel quality indication between a serving base station and the mobile terminal, and uplink channel quality indications amongst the terminal and a measurement set of target base stations. To generate UL channel quality indicators, the mobile station conveys a narrowband or broadband sounding reference signal, and serving and target base stations measure UL and DL performance metrics (e.g., RSRP, RSSI, or RSOT). In backward handover, UL channel state information from target cells is received at the serving base station through backhaul communication, and handoff is resolved based on both UL and DL quality reports. In forward handover, the set of UL quality reports are conveyed to the mobile station to determine a target cell for handoff.

Abstract: Systems and methodologies are described that facilitate selectively and simultaneously establishing multiple bearers in wireless communication networks. A core network entity in a wireless network can transmit a bearer establishment request to an access point comprising a list of bearers to establish with a related mobile device. The bearer establishment request comprising list of bearers includes separate non-access stratum (NAS) messages corresponding to each bearer in the list. The separate NAS messages can be linked to each bearer entry in the list. The access point can receive the list and attempt to initialize one or more radio bearers in the list. Since the NAS messages individually correspond to a given bearer, the access point can forward NAS messages to the mobile device only for bearers that are successfully initialized allowing selective establishment thereof. In addition, the access point can provide initialization status for the individual bearers to the core network.

Abstract: Techniques for quickly and efficiently performing handover are described. A user equipment (UE) may maintain a link with a serving cell and may communicate with this cell via the established link. The UE may have a candidate set of non-serving cells that are candidates for handover. The UE may maintain uplink synchronization with one or more non-serving cells in the candidate set, without having to maintain links with any of the non-serving cells. The UE may update uplink synchronization with the non-serving cells via an access procedure, e.g., send access probes to the non-serving cells and receive timing adjustments from these cells. One non-serving cell with which the UE has maintained uplink synchronization may be selected as a target cell for handover. The UE may then perform handover from the serving cell to the target cell, without performing uplink synchronization during the handover, which may improve handover latency and success rate.

Abstract: Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

Abstract: Facilitating user terminal (UT) access to wireless networks having base stations (BSs) of disparate access types is described herein. In some aspects, BS parameterization is provided to facilitate search and/or access to distinct types of network BSs. For instance, parameters can modify a likelihood of identifying or remaining coupled to restricted access (RA) BSs in a home Node B (HNB) deployment. In other aspects of the subject disclosure, a PLMN ID reserved for HNBs is provided comprising multiple region IDs. Where a UT identifies a home region, HNBs can be given preference over macro BSs. Additionally, the UT can keep track of HNBs and HNB regions that reject access to the UT, and implement a delay time to mitigate rapid signaling to foreign HNBs in a dense HNB deployment. Accordingly, the subject disclosure provides for more efficient UT access in heterogeneous access type networks.

Abstract: Systems and methodologies are described that facilitate notifying and detecting modification of system information in a wireless communication system. A mobile device may detect an inability to receive a paging message transmitted by a base station during a first time period, receive at least one system information block (SIB) transmitted by the base station during a second time period, and determine whether to receive one or more additional SIBs transmitted by the base station in the second time period based on information obtained from the at least one SIB received. The mobile device may detect an inability to receive a paging message upon entering a cell from being out of service or upon initial device starting up. The mobile device may determining whether to receive one or more additional SIBs by comparing a value tag of the at least one SIB received to a previously stored value tag.

Abstract: Systems and methodologies are described that facilitate notifying and detecting modification of system information in a wireless communication system. A mobile device may receive a first system information block (SIB) in a first time period, obtain from the first SIB at least one parameter related to modification of at least one SIB, and determine whether to receive the at least one SIB based on the at least one parameter obtained from the first SIB. The mobile device may receive a paging message in a second time period and may determine whether to receive one or more SIBs based on information obtained from the paging message. The mobile device may receive the first SIB in the first time period after entering a cell in an idle mode. The mobile device may receive the paging message in the second time period after accessing the cell.

Abstract: Techniques to support operation in a compressed mode and/or a continuous packet connectivity (CPC) mode are described. In an aspect, a user equipment (UE) may obtain an assignment of enabled subframes for the CPC mode and an assignment of transmission gaps for the compressed mode. The transmission gaps may be aligned with idle times between the enabled subframes. The UE may exchange data during enabled subframes not overlapping the transmission gaps and may skip data exchanges during enabled subframes overlapping the transmission gaps. The UE may make cell measurements during the transmission gaps. In another aspect, the UE may obtain enabled subframes and skipped subframes, exchange data during enabled subframes not corresponding to the skipped subframes, and skip data exchanges during the skipped subframes. In yet another aspect, the UE may receive orders on a shared control channel to quickly enable and disable the compressed mode.

Abstract: Methods, systems and apparatus for dispersing a group of user equipment (UEs) concentrated on a single channel is disclosed. After receiving a disperse command the UEs select a channel, and then select a cell. The channel selection may be performed using a random or pseudorandom function. The cell selection may be performed prior to camping on the cell. Prior to camping the UEs may test the acceptability of a candidate cell and/or may perform a cell reselection. The result of the dispersion is that the UEs are distributed amongst many channels (a, b, c, and d), where reference are found in FIGS. 1A and 1B.

Abstract: Techniques for supporting operation with enhanced uplink in inactive state are described. A user equipment (UE) may send an access preamble for random access while in an inactive state and may receive a message containing resources allocated to the UE. The allocated resources may be selected by a Node B from a pool of resources pre-allocated to the Node B for the enhanced uplink. The UE may send information (e.g., scheduling information and/or its UE identity) to the Node B using the allocated resources. The UE may receive an acknowledgement addressed to the UE based on the UE identity. The UE may remain in the inactive state and continue to use the allocated resources until they are de-allocated. Alternatively, the UE may transition to an active state and either continue to use the allocated resources or receive an allocation of new resources for the active state.
