Abstract: A multiple-subscriber identity module (multi-SIM) multi-standby communication device comprises a single radio resource unit shared by a plurality of virtual modems (VMs), each uniquely associated with a single one of a plurality of SIM cards. The access to radio resources in the single radio resource unit is controlled via a virtual modem controller (VMC). The VMC collects performance metrics such as requested service type and signal quality associated with each of the VMs. A VM is selected based on the collected performance metrics to perform a requested service. A serving VM is switched among the VMs based on the collected performance metrics. VM capabilities are dynamically configured based on the collected performance metrics. According to the collected performance metrics such as associated navigation information and requested service type, one or more VMs may be turned on or off, and certain VM capabilities may be enabled or disabled to save resources.

Abstract: A multiple-subscriber identity module (multi-SIM) multi-standby communication device comprises a single radio resource unit that is shared by a plurality of virtual modems (VMs), each uniquely associated with a single one of a plurality of SIM cards. Traffic related to the SIM cards are concurrently handled utilizing corresponding VMs. Available radio resource in the single radio resource unit are shared by the VMs based on corresponding VM states, namely, an active state, an idle state and a suspended state. VMs in an idle state concurrently monitor paging events and concurrently perform idle mode procedures such as location updating. VMs not related to an intended traffic are suspended. A VM related to the intended traffic is transitioned from an idle state to an active state to enable the communication for the intended traffic. Once the communication is complete, the suspended VMs are resumed to continue idle mode activities.

Abstract: A multiple-subscriber identity module (multi-SIM) multi-standby communication device comprises a single radio resource unit shared by a plurality of virtual modems (VMs). A first VM in an active state monitors its own associated cells and cells associated with remaining VMs in a suspended state. The active VM measures signal strength on available cells to track cell information such as cell quality and cell timing information for associated cells for the first active VM and for the remaining suspended VMs. When the suspended VMs are resumed, the single radio resource unit is synchronized to corresponding serving cells in an order determined based on the tracked cell timing information. With a synchronized serving cell, a suspended VM may bypass cell selection or reselection and directly camp on its serving cell. Otherwise, the suspended VM performs a cell selection or reselection selectively based on tracked cell information for a cell to camp on.

Abstract: A multiple-subscriber identity module (multi-SIM) multi-standby communication device comprises a single operating system (OS) and a single radio resource unit that is shared by multiple virtual modems (VMs) within a virtual modem framework (VMF). The OS maps VM tasks of the multiple VM to OS resource spaces according to corresponding VM IDs. The single OS may run the mapped VM tasks utilizing OS resources in the OS resource spaces. VM ID information is embedded in global variables and/or static variables that are utilized in the single OS to access OS resources. The OS may run VM tasks utilizing OS resources in OS resource spaces identified by corresponding VM IDs. The OS may re-use OS resources for VM tasks of different VMs, when needed, without duplicating the OS resources. VM tasks are scheduled to run on the single OS according to task priorities, which are determined based on corresponding VM environment.

Abstract: RF communications received by a wireless terminal from a servicing base station are used to determine the channel quality such as reported bit error probability (BEP). The RF communications may be in the form of RF bursts that are part of a data frame. An estimated BEP may be determined from the signal to noise ratio (SNR) of the RF bursts and or a sequence of soft decisions extracted from the RF bursts, and their historical performance. The SNR maps to an estimated BEP based upon the modulation format of the RF bursts. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). The reported BEP may be based upon the estimated BEP, RBER, and/or RBER threshold. The RBER threshold may be adaptively incremented or decremented depending upon whether or not the RF communications were properly decoded.

Abstract: RF communications received by a wireless terminal from a servicing base station are used to determine the BEP. These RF communications may be in the form of RF bursts that are part of a data frame. The signal to noise ratio (SNR) of the RF burst is determined and a sequence of soft decisions from the RF burst are extracted. The SNR maps to an estimated BEP based upon the modulation format and coding scheme of the RF burst. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). When the decoding is unsuccessful, the BEP is estimated only upon the estimated BEP derived from the SNR. Otherwise, both the estimated BEP and RBER may be used to determine the BEP.

Abstract: A heterosystem of two different materials, mismatched in terms of lattice constant or symmetry, may be formed with reduced defects by using a two step approach proposed in this invention. Nanowires are first grown on a semiconductor substrate, and then a thin film of the disparate crystallographically inconsistent material is grown from the nanowires through a two dimensional growth mode. The nanowire material may better match crystallographically to both the substrate and the grown film, or is simply the same as the grown film.
