Abstract:
Embodiments of the present disclosure allow a MS to dynamically adjust the mapping of a physical CINR measurement to an effective CINR. For some embodiments, an effective CINR value may be generated based on a physical CINR value and a measured packet error rate (PER) over one or more time periods. By dynamically adjusting the effective CINR reported back to a BS, the MS may allow the BS to select a coding scheme that effectively compensates for changes in channel conditions, which may improve system performance.
Abstract:
Embodiments of the present disclosure may provide a method of managing multi-mode operations such that a multi-mode MS may utilize the WiMAX sleep mode for monitoring the paging intervals of other supported radio access technologies. For example, certain embodiments may enable the MS to determine a set of WiMAX sleep mode parameters that align a WiMAX sleep window with a CDMA page listening window. Additionally, certain embodiments may provide enhanced MOB_SLP-REQ and MOB_SLP-RSP messages enabling the multi-mode MS to establish a WiMAX sleep mode based on the previously determined WiMAX sleep mode parameters. As a result, embodiments of the present disclosure may enable an MS to manage multi-mode operations, such that the MS 430 may better employ the WiMAX sleep mode for switching from the WiMAX network to the CDMA network to listen for CDMA paging.
Abstract:
In an area covered by multiple different radio access networks, a user equipment (UE) capable of accessing each of the multiple networks at the same time may provide additional service type setup for different call types. The UE registers each of the available call types with a first radio access network. Calls of one of the registered call types may be established, whether UE-originated or UE-terminated, with the first radio access network. When initiating a call of another type, the UE may initiate a different-typed call with another radio access network in the area, while maintaining the call of the first call type with the first radio access network.
Abstract:
Wireless communication within an area covered by multiple radio access networks may be accomplished where a user equipment (UE) is configured for first and second radio access networks. The UE attaches to the first radio access network, and, while maintaining the attachment to the first radio access network, also attaches to the second radio access network.
Abstract:
In geographical areas with incomplete coverage of Time Division Synchronous Code Division Multiple Access (TD-SCDMA) networks, it may be beneficial for a multimode User Equipment (UE) to handover to a Global System for Mobile Communications (GSM) network. Before handover, a multimode UE may receive an indication from a serving TD-SCDMA cell to enter a Discontinuous Reception (DRX) mode and perform measurement on a nearby GSM cell. After measurement, the UE receives a grant from the serving TD-SCDMA cell allowing the UE to transmit a measurement report to the serving TD-SCDMA cell. The TD-SCDMA cell may use the measurement report to determine if the multimode UE should handover to the GSM cell.
Abstract:
User equipments (UEs) will monitor each frequency in a multicarrier wireless radio access network for at least one control channel that may contain downlink data allocations or other such messages from the network. This monitoring may be dynamically controlled with a physical layer indication received by the UE from a node B that designates a number of carrier frequencies of all of the carrier frequencies of the network. In response to this physical layer indication, the UE will monitor at least one control channel in the designated carrier frequency or frequencies.
Abstract:
Certain aspects of the present disclosure propose techniques for service redirection in Time Division Synchronous Code Division Multiple Access (TD-SCDMA) and Global System for Mobile communications (GSM) hybrid mobile terminals.
Abstract:
Certain embodiments of the present disclosure provide a method for communicating, by a multi-mode mobile station (MS), with first and second networks via first and second radio access technologies (RATs). The method generally includes determining a first set of one or more paging parameters in an effort to establish a listening interval of a sleep cycle of the first network that aligns with a sleep interval of a control channel cycle of the second network and communicating the first set of paging parameters to a base station of the first network in a request to establish the sleep cycle of the first network.
Abstract:
Embodiments of the present disclosure propose a method and apparatus for ensuring each mobile station serviced by a base station does not miss a new version of a DCD/UCD message before the new version takes effect.
Abstract:
Methods and systems or broadcasting the fast power control message in wireless communications systems are provided. In certain embodiments, the methods and systems can include receiving Carrier to Interference-plus-Noise Ratio (CINR) values from multiple mobile stations, determining a power adjustment value for each mobile station based on the CINR values, grouping the mobile stations based at least on the CINR values, and transmitting a fast power control message for each group with a different number of repetitions.
