| 20120294173 | APPARATUS AND METHODS FOR CLIENT SERVER INTERACTION IN HYBRID NETWORK ENVIRONMENTS - Methods and apparatus for modifying network management for hybrid operation. In one embodiment, the networks include an LTE network and a CDMA 1X network, and a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the mobile device cannot simultaneously measure information for the LTE network while connected to the CDMA 1X networks, the mobile device modifies measurements and behaviors reported to the LTE network. In one implementation, the mobile device accounts for the time switched away from the LTE network in one or more subsequent reports thereto. | 11-22-2012 |
| 20120294291 | APPARATUS AND METHODS FOR NETWORK ASSISTED HYBRID NETWORK OPERATION - Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1× operation), a mobile device can place CDMA 1× voice calls while registered with the LTE network. However, since the LTE and CDMA 1× networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1× paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1× pages, overall LTE network performance is minimally affected. | 11-22-2012 |

Consequently, the present invention in one embodiment provides a method for a client device to properly prioritize and re-schedule maintenance tasks. For example, CDMA 1X cell selection (or cell re-selection) procedures have flexible time constraints, and can be postponed (or expedited) to minimize impact on LTE network traffic. | 11-22-2012 |

In a second embodiment, neighbor cell search durations are based on a multitude of physical layer metrics from one or more cells. In one variant, the multitude of physical layer metrics may include signal strength and quality metrics from the serving base station as well as signal strength and quality indicators from neighbor cells derived from the cells respective synchronization sequences. | 08-01-2013 |

In one exemplary embodiment, the distribution of Long Term Evolution (LTE) DRX measurements is staggered or distributed across multiple DRX cycles (which may be contiguous or non-contiguous) so as to reduce the transceiver activity and power consumption. The exemplary UE in one implementation only performs a subset of measurements during each DRX cycle. By staggering or distributing cell measurements over multiple DRX cycles, the UE can improve power consumption, while still conforming to measurement requirements. | 10-24-2013 |
| 20130286853 | APPARATUS AND METHODS FOR NETWORK DETECTION AND MITIGATION OF HYBRID CLIENT DEVICE OPERATION - Methods and apparatus for network-based detection and mitigation of hybrid client device reception outage events. For example, in one embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE.

| 20130315119 | TUNE BACK COORDINATION WITH CONNECTED MODE DISCONTINUOUS RECEIVE - A method is disclosed for coordinating a user equipment's communication with a network during tune back with C-DRX (connected mode discontinuous receive). When a user equipment tunes back to a network after a tune away or a signal fade, a scheduling request is sent to the network to indicate the tune back as quickly as possible.

| 20090307386 | Restore PCIe Transaction ID on the Fly - Restoring retired transaction identifiers (TID) associated with Direct Memory Access (DMA) commands without waiting for all DMA traffic to terminate is disclosed. A scoreboard is used to track retired TIDs and selectively restore retired TIDs on the fly. DMA engines fetch a TID, and use it to tag every DMA request. If the request is completed, the TID can be recycled to be used to tag a subsequent request. However, if a request is not completed, the TID is retired. Retired TIDs can be restored without having to wait for DMA traffic to end. Any retired TID value may be mapped to a bit location inside a scoreboard.

| 20100064072 | Dynamically Adjustable Arbitration Scheme - A network arbitration scheme is disclosed that manages device access fairness by selectively and dynamically increasing a requestor queue's likelihood of being serviced. A requestor queue increases its service priority by duplicating a request entry onto a set of priority rings maintained by arbitration hardware in a host bus adapter. Duplication occurs when (1) a requestor's queue fill count (the number of descriptors stored in the queue) exceeds a watermark level or (2) a requestor's queue timer times out. In the case of time-out, the requester in the lower priority ring will duplicate itself in the higher priority ring. Because the arbitration hardware services requesters using a round robin selection scheme, the likelihood of a requestor queue being serviced increases as the number of its duplicate request entries on a priority ring increases. Upon being serviced, the requester is able to perform the requested action. | 03-11-2010 |
