  • Patent number: 11419063
    Abstract: A wireless transmit/receive unit (WTRU) is configured to receive a WTRU-specific configuration of WTRU-specific sounding reference signal (SRS) subframes for performing SRS transmissions. The WTRU is configured to receive a trigger in a subframe to transmit a first SRS. The WTRU is configured to select a first subframe. The WTRU is configured to determine that a maximum power would be exceeded in a symbol in the selected first subframe. The WTRU is configured to, on a condition that transmission of at least one other SRS would at least partially overlap in the symbol in the selected first subframe, scale transmission powers of the first SRS and the at least one other SRS equally to comply with the maximum power. The WTRU is configured to transmit, in accordance with the scaled transmission powers, the first SRS in the selected subframe and the at least one other SRS.

  • Patent number: 11394447
    Abstract: Methods and apparatus are described. A method, implemented in a wireless transmit/receive unit (WTRU) includes monitoring a first control channel search space (SS) associated with a first normal beam set comprising a first beam set. The WTRU initiates extended monitoring and monitors, subsequent to a trigger based on a measurement by the WTRU, a control channel SS associated with an extended beam set comprising the first beam set and one or more additional beam sets. The WTRU determines a second beam set from the extended beam set. The determination is based on a received control channel beam switch command or based on a control channel SS in which a beam switch command is received. The WTRU monitors a second control channel SS associated with a second normal beam set comprising the determined second beam set.

  • Patent number: 11336500
    Abstract: Methods and apparatus for initial cell search and selection using beamforming are described. An apparatus is configured with multiple receive beams and includes an antenna and a processor. The processor is operatively coupled to the antenna and sweeps a respective one of the multiple receive beams during each of multiple synchronization sub-frames, using a pre-defined sweep time and dwell period, to detect a synchronization signal. The processor also obtains symbol timing information and a synchronization signal index from the detected synchronization signal. The obtained synchronization signal index corresponds to a synchronization signal index of the set. The process decodes a first broadcast channel using the obtained symbol timing information, the obtained synchronization signal index and a predefined or blind-coded symbol distance between the detected synchronization signal and the first broadcast channel.
