Patent number: 11973597Abstract: Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.Type: GrantFiled: August 10, 2021Date of Patent: April 30, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Marian Rudolf, Paul Marinier, Diana Pani, Ghyslain Pelletier, Christopher R.

Patent number: 11729691Abstract: A method and base station are disclosed. The base station comprises a transceiver and a processor. The base station transmits a system information block (SIB) to a wireless transmit/receive unit (WTRU), wherein the SIB indicates random access transmission uplink resources. After transmitting the SIB, the base station receives a random access preamble from the WTRU. After receiving the random access preamble, the base station receives, using one or more of the uplink resources indicated by the SIB, a first message from the WTRU, wherein the first message includes a first radio network temporary identifier (RNTI) of the WTRU. After receiving the first message, the base station transmits a second message to the WTRU, wherein the second message is derived from a second RNTI, the second RNTI being different than the first RNTI. The base station may be configured to communicate with the WTRU on a plurality of cells.Type: GrantFiled: November 16, 2020Date of Patent: August 15, 2023Assignee: Pantech Wireless, LLCInventors: Diana Pani, Rocco DiGirolamo, Christopher R.
