  • Patent number: 9572136
    Abstract: Data bits are mapped to a lower number of slots than the number of slots available for a retransmission frame and control channels are transmitted in all available slots of the retransmission frame. The number of available slots in the retransmission frame is greater than the number of available slots in the original frame.

  • Patent number: 9397767
    Abstract: After a maximum noise rise for a cell is set, a maximum noise rise for each mobile station is allocated within the cell. The actual noise rise from each mobile station within the cell is measured at a base station and signaled to a network. When the cell uses enhanced dedicated channel (E-DCH), the contribution to noise rise of E-DCH signaling is determined and received signal code power (RSCP) at the base station is measured. The RSCP measurement is decoded to determine contributions from mobile stations within and outside the cell; contributions from mobile stations within the cell are calculated; and the network is notified of the measured noise rise. In addition a compensation value may be applied to compensate for temperature induced noise.

  • Patent number: 9288151
    Abstract: A power manager for a mobile device comprises a traffic shaping unit (30) and a management unit (26). The traffic shaping unit is incorporated into a networking layer (8) of a mobile device architecture. The traffic management unit spans application layer (7) and networking layer (8) of the mobile device architecture. The traffic shaping unit and management unit are connected via a feed path (73). The management unit (26) is provided with inputs (74) to receive measurements of external parameters (65 to 69). The management unit further comprises a processor (20) to process the received measurements and a traffic shaping function generator (21) to receive the processed measurements and generate a traffic shaping function. The management unit (26) inputs the generated traffic shaping function to the traffic shaping unit (30) via the feed path (73), whereby the traffic management unit controls transmissions from the mobile device.

  • Patent number: 8358622
    Abstract: Resources are allocated in a communication system by setting specific time and frequency chunks within a band to provide localized and distributed resources for each of localized and distributed users. The signalling of resource allocation for each user is in the chunk at the same frequency range as the frequency range of the allocated resource, or a subset of the frequency range of the allocated resource.

  • Patent number: 8355377
    Abstract: A method of signaling on a downlink, information regarding scheduling resources allocated in uplink, is provided, wherein the information is contained in an uplink scheduling information message, which is formatted to contain a subset of content of any subsequent uplink scheduling information message in an ordered set of message formats. Each uplink scheduling information message selected from the set is punctured into a symbol of a downlink user data allocation.

  • Patent number: 8160040
    Abstract: In a method of downlink operation in a communication system having a network controller, a base station and a terminal, one communication channel is scheduled by the base station; and one communication channel is scheduled by the network controller. The terminal listens to the channel scheduled by the base station at predetermined times known to the terminal and the network controller. Information is signalled from the network controller to the base station, relating to the predetermined times.

  • Patent number: 7805155
    Abstract: A mobile terminal selects neighbor cell(s) to use in receiving a broadcast or multicast by deriving an estimate of cell quality for each neighbor cell; comparing the estimated quality with a minimum acceptable quality; and choosing those neighbor cells having the highest quality from the acceptable neighbor cells. The estimate of cell quality is based on a parameter of the difference between a common pilot channel transmit power and a secondary common control physical channel transmit power that is transmitted to the mobile terminal on a multimedia broadcast multicast control channel.

  • Publication number: 20090305723
    Abstract: A method of determining position dependent information from one or more terminals in a cell involves transmitting at least two messages; wherein one message covers a first area in the cell; and one or more further messages cover other areas in the cell; and receiving responses from terminals dependent upon the messages received by each terminal; wherein the areas of coverage of the at least two messages at least partially overlap.

  • Publication number: 20090275356
    Abstract: A method of controlling interference between adjacent communication systems (1, 2) each of which operates in a predetermined frequency band. The method comprises reducing transmit power levels at frequencies (13, 14) at each end (10, 11) of the frequency band (12) and maintaining power levels at other frequencies (15) of the frequency bands (12), such that interference with frequencies at an end of the frequency band of an adjacent system is reduced.

  • Publication number: 20090245185
    Abstract: A method of scheduling groups of mobile users includes setting a group identifier for each mobile user and scheduling physical layer resources at a base station for those users requiring resources. The physical layer resources are divided into sub-resources shared between mobile users having the same group identifier and provide an indication with the physical layer resources of the occurrence and position within the physical layer resources of the sub-resources allocated to each mobile user in the group.
