  • Publication number: 20240063848
    Abstract: A User Equipment (UE) configured to determine one or more beam correspondence conditions for use during an inactive mode of the UE. The beam correspondence conditions are determined based, at least in part, on a range of a discontinuous reception (DRX) cycle used by the UE.

  • Publication number: 20240064859
    Abstract: A User Equipment (UE) configured to control lengths of one or more monitoring cycles of the UE based, at least in part on a range of a discontinuous reception (DRX) cycle and one or more power conditions of the UE. The monitoring cycle is used to select a beam for transmission by the UE. The DRX cycle is used by the UE during RRC_INACTIVE state and the range of the DRX cycle determines one or more beam correspondence conditions.

  • Patent number: 8976840
    Abstract: The method disclosed herein is implemented in a radio receiver to detect an AWGN channel, where the radio receiver comprises a rake receiver. The radio receiver receives signals transmitted via a propagation channel from a transmitter, and determines that the propagation channel is an AWGN channel when a filtered version of a minimum value of a metric is lower than a threshold value. The metric relates to a difference between a normalized measured power profile of the propagation channel and a normalized power template, which normalized power template is dependent on predetermined sampling timing shifts and on rake finger positions within the rake receiver.
    Type: Grant

  • Patent number: 7372837
    Abstract: Methods and apparatus for processing a data stream for high speed wireless Transmission. At the transmission side, the methods and apparatus rate-match an encoded stream of combined information bits and corresponding cyclic redundancy bits in two stages. The first rate matching stage punctures (throws away) or repeats bits such that the number of bits in the data stream is equal to the size of a mobile unit buffer. The second rate matching stage further punctures or alternately repeats bits in the data stream so that the total number of bits in the resulting data stream is equal to the frame size of the transport channel. The bits punctured or repeated by the second rate matching varies according to different versions of parameters for any retransmissions. At the receiver side, the two-stage rate matching is reversed to restore the original encoded data stream. The encoded data stream is then decoded and repeated, if necessary.
