  • Reduced radio resource control connectivity
    Patent number: 9622286
    Abstract: Embodiments of the present invention relate to reduction of radio connectivity of a bearer service. Upon detection of low data transfer activity within a bearer service, radio connectivity of the bearer service is reduced so as to reduce signaling overhead in an air interface. However, a core network connection of the bearer service is maintained.
    Type: Grant

  • Controlling retransmissions
    Patent number: 9379850
    Abstract: A method and apparatus for controlling retransmissions in multipoint reception is disclosed. In the method it is determined that additional information is needed for decoding of at least one received information block. A procedure is selected for obtaining the additional information from a plurality of options to proceed based on information about predicted result of at least one of the options. In accordance with an aspect an indication of one of a positive acknowledgement of the information block, a negative acknowledgement of the information block and suspension of retransmission of the information block is generated and communicated on a retransmission control channel.
