Patent number: 11956725Abstract: A wireless transmit/receive unit (WTRU) may include one or more antennas and a first transceiver operatively coupled to the antennas. The one or more antennas and the first transceiver may be configured to receive a first signal from a network using zero energy from the WTRU. The one or more antennas and the first transceiver may be further configured to extract energy from the first signal. The first transceiver may be further configured to examine a separation between energy threshold events to decode an energy signature of the first signal. The first transceiver may be further configured to activate a second transceiver operatively coupled to the one or more antennas if the decoded energy signature matches a stored energy signature, wherein the second transceiver is powered by the WTRU.

Publication number: 20230319747Abstract: Apparatus for paging for highly directional systems. A WTRU receives a default and/or a dynamic set of active SSBs which indicates the beams/SSBs is used to receive paging DCI, e.g. DCI scrambled with P-RNTI, over PDSCH. A WTRU utilizes the default and/or dynamic set of active SSBs in order to determine PDCCH monitoring occasions, PMOs, that are monitored in the WTRU's paging occasions, POs. A WTRU sends paging activating requests to activate a suitable SSB using associated UL signal/resources, if the suitable SSB fulfills a SSB criteria, if the activation duration has elapsed and if the monitoring duration has elapsed. A WTRU may send one or more paging activation requests to activate multiple SSBs, e.g., a field of view, FOV, around a suitable SSB. Said paging activation requests implements a minimal feedback-based paging procedure for paging in highly directional systems, to which the gNB replies with paging configuration for the suitable SSB.Type: ApplicationFiled: September 2, 2021Publication date: October 5, 2023Applicant: InterDigital Patent Holdings, Inc.Inventors: Sanjay Goyal, Hussain Elkotby, Ravikumar Pragada, Tanbir Haque, Alpaslan Demir, Patrick Cabrol, Mihaela Beluri

Publication number: 20220386366Abstract: A wireless transmit receive unit (WTRU) may receive a set of candidate resources, which may be used for transmission. The WTRU may periodically perform CCA on a channel (e.g., before transmitting on the channel). When the channel is determined to be free, the WTRU may determine a resource for transmission from the candidate resources. The resource may be determined based on the time remaining in the time period. For example, when the time remaining in the time period is shorter, the WTRU may determine to transmit on a resource that comprises more frequency resources. The WTRU may determine a Multiple Input Multiple Output (MIMO) scheme based on the number of frequency resources. The WTRU may send a transmission on the resource, which may include a demodulation reference signal (DM-RS). The DM-RS may indicate the resource used from transmission to a receiver of the transmission.Type: ApplicationFiled: August 11, 2022Publication date: December 1, 2022Applicant: IDAC Holdings, Inc.Inventors: Janet A.
