    Abstract: Methods, devices, processors and computer program products for mobile terminal-based Radio Resource Management (RRM) and network optimization. The mobile terminal measures or otherwise obtains radio condition measurements (such as received power, interference, mobile transmit power and the like) and/or geographical location measurements. The radio condition measurements and/or location measurements are compared against historical data and/or target Key Performance Indicators (KPI) and, based on the comparison, a determination can be made as to whether adjustment of RRM parameters is warranted. By providing for RRM management at the mobile terminal level, as opposed to a cell or Radio Network Controller (RNC) level, better granularity of management is realized in the overall radio network. Further, individual mobile terminals can better tailor their radio resource needs to meet their conditions of use and, as such, better overall service can be realized by the individual mobile terminals in the network.

  • Patent number: 9325368
    Abstract: A period is defined to execute the sequences (processes) of communication data acquisition, measuring communication quality, communication quality data acquisition, and channel change. Processing is controlled to execute each process within a time limit set for each process and execute all processes in one cycle. This avoids that a delayed sequence influences and delays other sequences and can suppress delays. If processing fails to finish a sequence, it will resume the same sequence in the next cycle. For communication stations sharing timeslots, there are provided offset periods differing in length before the start of carrier sense in the timeslots for these stations. Consequently, even under a condition in which packet collision may occur, the collision of packets can be avoided by detecting a packet sent to another station by carrier sense. Moreover, by controlling sending priority of packets in the send queue of the gateway, sending delay can be avoided.

  • Patent number: 8934403
    Abstract: The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving, at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating, by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.

  • Patent number: 8934447
    Abstract: The present invention relates to a method and apparatus for performing communications by adjusting a resource unit. Efficient allocation of resource units can minimize power consumption. The minimization of power consumption brings about great advantages to M2M (machine-to-machine) communication. A terminal can transmit or receive data via different resource units. In this case, the resource units can be determined by MS. That is, some MS may use a particular resource unit, while the others may use a different resource unit. When different resource units are given, corresponding radio resource regions are also determined differently from one another. However, the total number of tones corresponding to the resource units may be the same.

  • Patent number: 8917679
    Abstract: A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, orb) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.
