Abstract: Methods for saving power and facilitating transitions from power-saving states back to active states in mobile stations are provided. A base station transmits indication of a periodic interval at which system configuration information is to be transmitted, periodically transmits a current version of system configuration information and in advance of an action time of a new version of system configuration information, periodically transmits the new version of system configuration information at the periodic interval; and transmits a flag indicating whether the new version of system configuration information is available. In respect of each of at least one mobile station in a power-saving state, in which the mobile station (MS) is configured on a per-MS basis to periodically wake up and check for the presence of an information block relevant to the MS, the base station transmits an information block presence indicator indicative of whether the information block is present.

Abstract: Downlink codes may be chosen autonomously for femtocells in a wireless communication environment. Downlink transmissions are received from Home NodeBs that are neighbors of the femtocell and macrocell base stations near the femtocell. The downlink transmissions are evaluated to recognize a first set of detected downlink codes that each have a pilot energy above a predetermined detection threshold. An optimal downlink code is selected for use in connection with serving user equipment of the femtocell. The optimal downlink code is based upon the first set of detected downlink codes and selected as a downlink code from a set of downlink codes reserved for the femtocell. The optimal downlink code may be an available downlink code with a smallest amount of detected energy or a randomly selected downlink code from the available downlink codes.

Abstract: Providing for fast allocation of additional carriers in multi-carrier wireless communication systems is described herein. By way of example, high layer protocols can be employed to allocate additional carriers to UEs in a wireless network. Additionally, management of the additional carriers can be accomplished via high speed lower layer signaling protocols. Management can involve activating/deactivating the additional carriers, instructing the UE to provide carrier feedback, monitor pilot or control channels of such carriers, or the like. Because lower layer signaling is relatively fast, activation or deactivation of the additional carrier can be quickly implemented in response to contemporaneous changes in channel conditions. Thus, changes to signal quality or network loading can be determined and utilized to customize carrier activation in near real-time, providing efficient resource allocation while conserving UE battery life.

Abstract: A variety of wireless communication methods and apparatus for supporting reconfiguration of radio link control (RLC) parameters are disclosed. A radio resource control (RRC) reconfiguration message is generated that indicates that an RLC unit in a wireless transmit/receive unit (WTRU) or a universal terrestrial radio access network (UTRAN) should be reconfigured from supporting flexible size RLC protocol data units (PDUs) to supporting fixed size RLC PDUs. If an information element (IE) “one sided RLC re-establishment” is present in the RRC reconfiguration message, only a receiving side subassembly in the RLC unit is re-established. Otherwise, both the receiving side subassembly and a transmitting side subassembly in the RLC unit are re-established. Flexible size RLC PDUs may be discarded and a message indicating the discarded flexible size RLC PDUs may be transmitted. The flexible size RLC PDUs may be modified such that they correspond to a set of pre-defined sizes.

Abstract: In one embodiment, a router selects a particular peer from an original update group used with an Exterior Gateway Protocol (EGP) such as Border Gateway Protocol (BGP). The original update group includes a plurality of peers of the router that share a same outbound policy and that receive common update messages, from the router, of routing table information. The router determines that the particular peer is a potential slow peer based on a first type of indicia, wherein a slow peer is a peer that cannot keep up with a rate at which the router generates update messages over a prolonged period of time. The router confirms that one or more second types of indicia are consistent with the particular peer being a slow peer. In response to the confirmation, the router determines that the particular peer is a slow peer.

Abstract: In a broadband wireless communication system, a primary control signal may be relocated within the operation band for transmission while avoiding interference. For example, if the primary control signal employs P contiguous sub carriers, the primary control signal can be placed in any section of the band that has P contiguous subcarriers. If a narrow-band interferer appears at one end of the band, the primary control signals can be placed at the other end. If the interferer appears in the middle, the primary can be relocated to either end of the band. The placement of primary control signals can be changed as the interference environment changes.

Abstract: In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

Abstract: Systems and methodologies are described that facilitate resource allocation and management in a wireless communication system. As described herein, a resource grid structure can be utilized to allocate resources for respective users corresponding to a given channel (e.g., a Physical Uplink Control Channel (PUCCH)). The resource grid can be constructed using one or more cyclic shifts and a set of four orthogonal covers to provide improved efficiency in resource usage. Further, slots in the resource grid can be allocated to respective users based on user indexes via one or more resource allocation functions. For example, a resource allocation function can step along a first orthogonal cover at increasing cyclic shifts, alternate between second and fourth orthogonal covers at increasing cyclic shifts upon exhaustion of the first orthogonal cover, and step through a third orthogonal cover at increasing cyclic shifts upon exhaustion of the second and fourth orthogonal covers.

Abstract: Transmission monitoring can be used to determine the optimum data rate for a channel. The transmission monitoring can include sending data packets in the channel using various data rates. At least some data packets are sent using the current optimum data rate, a rate lower than the current optimum data rate, and a rate higher than the current optimum data rate. One of these data rates can be selected as the new optimum data rate. In one embodiment, if the current optimum data rate is less than a predetermined data rate, then the client is triggered to begin scanning for other available access points.

Abstract: The present disclosure provides a system and a method for providing mobility management and out-of-coverage indication in a hybrid system comprised of conventional LMR sites and trunking LMR sites. If a radio is located at a conventional site, the radio provides its location and user group data to the disclosed system through its traffic channel when the channel is idle. If the radio is located at a trunking site, the radio provides its location and user group data to the disclosed system through the trunking site's control channel. Knowledge of the radio's current location and user group data is used to provide dynamic call routing and data management within the disclosed system. The disclosed system and method provides seamless communication between a trunking site and a conventional site while concurrently enhancing the hybrid system to provide mobility management and out-of-coverage indication features typically associated with a stand-alone trunking system.
