  • Patent number: 9226271
    Abstract: A user equipment implements a method of processing indication messages, such as SCRI (signaling connection release indication) messages. For at least one RRC (radio resource control) state, if the current RRC state of the UE is a result of a previously sent indication, the UE inhibits itself from sending a further indication message.

  • Patent number: 9144104
    Abstract: A user equipment implements a method of processing indication messages, such as SCRI (signalling connection release indication) messages. If upper layers indicate that there is no more packet switched data for a prolonged period, then if a count of how many indication messages have been triggered in at least one RRC (radio resource control) state is less than a maximum number, the UE increments the count, and a cause is set in the indication message, and the indication message is sent.

  • Patent number: 9060317
    Abstract: A method, computer readable medium and mobile device for operating using more than one Radio Access Technology (RAT) are provided. When the mobile device is operating in a serving cell of a first RAT, it obtains, through at least one of wireless access radios in the mobile device, a first set of candidate information from a message transmitted for the serving cell. It also obtains, through at least one of the wireless access radios, a second set of candidate information from a message transmitted for a neighbor cell of the serving cell. The mobile device considers the candidate information from the first set and the candidate information from the second set for reselection by the mobile device.

  • Patent number: 9060314
    Abstract: A wireless cellular telecommunications device stores a first parameter obtained from system information of a first cell and measures an attribute of a signal received from a candidate cell, determines if the candidate cell is a closed subscriber group cell, and evaluates the candidate cell for re-selection. If the candidate cell is determined to be a closed subscriber group cell, the evaluation of the candidate cell for re-selection is based on at least the measured attribute irrespective of the first stored parameter, that first stored parameter indicating a minimum value for the measured attribute.

  • Patent number: 9049646
    Abstract: Methods and apparatus for network searching are disclosed. An example method is performed by a mobile device related to public land mobile network (PLMN) selection, the method comprising registering with a visited PLMN, determining whether a priority search inhibit list includes a cell global identity of a serving cell, dependent at least in part on determining that the priority search inhibit list does not include the cell global identity of the serving cell and dependent at least in part on a priority search period, searching for a second PLMN having a higher priority than the visited PLMN, and dependent at least in part on the searching being unsuccessful, adding the cell global identity of the serving cell to the priority search inhibit list.

  • Patent number: 8942205
    Abstract: Methods, apparatus and articles of manufacture for performing idle mode mobility measurements in a mobile network are disclosed. An example method in a user equipment (UE) disclosed herein comprises receiving, from the mobile network, a system information block (SIB) message specifying idle mode mobility measurement is to be performed. If the measurement parameter threshold is not configured in the SIB message or if the SIB message includes an indication to not use a configured measurement parameter threshold in the SIB message, the UE sets a measurement parameter threshold for idle mode mobility measurement.

  • Patent number: 8908799
    Abstract: Systems and methods of performing ASK or QAM modulation with uneven distance between symbols are provided. Different bit positions mapped to such symbols are assigned to different receivers, with the result that there are different BER performances among bits sent from a transmitter to the different receivers. Bits for multiple receivers are mapped to a UASK constellation or a UQAM constellation without using superposition.

  • Patent number: 8824424
    Abstract: A method for coordinating communications between a user equipment and a base station is presented. The method includes receiving an assignment of a first set of timeslots for at least one of uplink and downlink communications between the user equipment and the base station. The method also includes transmitting to the base station an instruction to delay a reduction of a number of timeslots monitored by the user equipment to less than the first set of timeslots for communications. In some implementations, the instruction comprises at least one of a predetermined communication and a block including at least one of a dummy block format and a specified block format. The method may include transmitting a control block to the base station, the control block identifying one or more timeslots being monitored by the user equipment.
