Patent number: 11483781Abstract: Systems, methods, and instrumentalities are disclosed for LTE operation in an unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may establish a connection with a first cell on a licensed frequency band. The WTRU may receive a first downlink transmission from a second cell operating on an unlicensed frequency band. The WTRU may determine that a synchronization signal transmission from a third cell operating on the unlicensed frequency band is transmitted using one or more resource elements. The WTRU may perform frequency and/or timing estimation based on the synchronization signal transmission. The WTRU may perform rate matching around the one or more resource elements that correspond to the synchronization signal transmission. The WTRU may perform rate matching around the one or more resource elements by de-mapping symbols of the downlink transmission.Type: GrantFiled: April 17, 2019Date of Patent: October 25, 2022Assignee: InterDigital Patent Holdings, Inc.Inventors: Pouriya Sadeghi, Janet A.

Publication number: 20220329400Abstract: Techniques for efficient downlink control with a large number of carriers and/or TTis are described. Techniques for blind decoding reduction may include making the search space and/or aggregation level of candidates for a first PDCCH/E-PDCCH associated with the characteristics of a second received PDCCH/E-PDCCH. Techniques may include embedding DCI for a set of serving cells and/or TTis in a PDSCH. DCI for a set of serving cells and/or TTis may be included in single PDCCH/E-PDCCH. To reduce overhead, carrier indicator field interpretation may be associated with the serving cell or TTI from which the PDCCH/E-PDCCH containing the downlink control information is received, or the group of cells or TTis to which the PDCCH/E-PDCCH containing the downlink control information belongs.Type: ApplicationFiled: June 23, 2022Publication date: October 13, 2022Applicant: InterDigital Patent Holdings, Inc.Inventors: Ghyslain Pelletier, Paul Marinier, Marian Rudolf, J.
