Abstract: Schemes to time-align transmissions from multiple base stations to a terminal. To achieve time-alignment, differences between the arrival times of transmissions from the base stations, as observed at the terminal, are determined and provided to the system and used to adjust the timing at the base stations such that terminal-specific radio frames arrive at the terminal within a particular time window. In one scheme, a time difference between two base stations is partitioned into a frame-level time difference and a chip-level time difference. Whenever requested to perform and report time difference measurements, the terminal measures the chip-level timing for each candidate base station relative to a reference base station. Additionally, the terminal also measures the frame-level timing and includes this information in the time difference measurement only if required. Otherwise, the terminal sets the frame-level part to a predetermined value (e.g., zero).

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: Un sistema para transferencia intercelular entre sistemas para un sistema de comunicaciones inalámbricas soporta transmisión descendente y transmisión ascendente del equipo del usuario (UE) para diferentes tecnologías de acceso por radio, incluyendo sistemas síncronos y asíncronos. Los fallos de conexión de latencia y transferencia intercelular se reducen mediante un nodo de acceso (NodeB) que radio difunde la información acerca de los sistemas contiguos (blancos) cuando la capacidad de recepción del UE (RX) es tanto hacia dentro como hacia fuera del margen de recepción del blanco. Una cadena RX individual es suficiente, aunque una transición entre una red de área amplia inalámbrica (WWAN) hacia una red de área local inalámbrica (WLAN) se puede beneficiar ventajosamente de la operación simultánea en dos cadenas Rx. La lista optimizada de los sistemas RAT contiguos (blancos) se radiodifunde desde la red, incluyendo los parámetros de medición e instrucciones de reporte. Con esto, el reporte conducido del UE reduce al mínimo las latencias. El UE reporta las búsquedas de otros sistemas a la red sólo si es necesario para una transferencia intercelular. Además, las peticiones de transferencia intercelular se pueden empaquetar con la información de medición de otros sistemas, si necesario, para eficacias adicionales.

Abstract: Techniques for transmitting signaling information for broadcast and multicast services are described. A base station transmits signaling information for each service in accordance with a schedule that includes a repetition period and a modification period. The signaling information is sent in each repetition period to allow wireless devices to quickly obtain this information. Changes to the critical signaling information are permitted at the start of each modification period, which is an integer multiple of the repetition period. Whenever the critical signaling information for a given service is changed in a given modification period, a notification indicator for the service is set in an entire preceding modification period to inform the wireless devices of the impending change. The wireless devices can detect the notification indicator being set in the preceding modification period and can retrieve the updated critical signaling information in the following modification period.

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: 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.

Abstract: Facilitating user terminal (UT) access to wireless networks having disparate types of base stations (BSs) is described herein. By way of example, a distinct identifier (ID) can be reserved for a particular type of network access point (e.g., restricted or general access, full or fractional re-use, transmit power, cell size, etc.). The distinct ID can be broadcast by such access points, identifying the access point type. In some aspects, the distinct ID can be unicast to a terminal that is within a predetermined region of the network. Thus, at least within such region, the terminal can be directed to search for or handoff to a preferred type of access point (such as a home Node B). In such aspects, by providing regional-specific access, the subj ect disclosure can significantly reduce overhead signaling outside a home region where a home or preferred access point is expected to be found.
