Publication number: 20240057042Abstract: A radio transmitter is configured to operate in accordance with a first predetermined OFDM radio protocol. The transmitter reserves, within a timeslot with a predetermined timeslot duration, a reserved set of time-frequency resource units not available for an OFDM data channel defined by the first protocol. The transmitter allocates, within the timeslot, an allocated set of R time-frequency resource units for the OFDM data channel defined by the first protocol, wherein a number M of time-frequency resource units are included in both the allocated set and the reserved set, wherein the value R is such that R>N and R?M?N, where N is a predetermined maximum number of time-frequency resource units that can be used to carry the data channel. The transmitter then transmits data indicative of the allocated set of R time-frequency resource units and data indicative of the reserved set of time-frequency resource units.Type: ApplicationFiled: July 21, 2023Publication date: February 15, 2024Applicant: Nordic Semiconductor ASAInventors: Karol SCHOBER, Mauri NISSILÄ

Publication number: 20220303050Abstract: A digital radio receiver receives an encoded digital radio signal comprising a plurality of bits. The receiver determines a plurality of soft bits representing estimates of the bits and stores the soft bits in a rate de-matching buffer. The receiver calculates a first linear combination of soft bits from a first subset of the buffer and a second linear combination of soft bits from a second subset of the buffer. The receiver calculates a ratio between the first and second linear combinations and compares the ratio to an expected value. The receiver then determines its operational state based on the comparison.Type: ApplicationFiled: June 22, 2020Publication date: September 22, 2022Applicant: Nordic Semiconductor ASAInventors: Hanna-Liisa TIRI, Mauri NISSILÄ

Publication number: 20220069885Abstract: A radio device receives data from a base station that transmits a first radio signal, carrying a first data block, in a first time window, and a second radio signal, also carrying the first data block, in a different, second time window. The radio device comprises first and second antennas, receive circuitry, and a switch for selectively connecting the receive circuitry to the first antenna or to the second antenna. It is configured to sample the first radio signal, received by the first antenna in the first time window, to generate first sampled data; disconnect the first antenna from the receive circuitry and connect the second antenna; sample the second radio signal, received by the second antenna in the second time window, to generate second sampled data; and use both the first sampled data and the second sampled data to decode the first data block.Type: ApplicationFiled: December 10, 2019Publication date: March 3, 2022Applicant: Nordic Semiconductor ASAInventor: Mauri NISSILÄ

Publication number: 20220061108Abstract: A radio device sends a random-access request message to a base station and receives a random-access response message from the base station. A plurality of data transport blocks are thereafter transmitted in a first direction between the radio device and the base station, but the radio device does not send a connection-setup complete message to the base station until all of the plurality of data transport blocks having been transmitted.Type: ApplicationFiled: December 11, 2019Publication date: February 24, 2022Applicant: Nordic Semiconductor ASAInventors: Mauri NISSILÄ, Hanna-Liisa TIRI

Patent number: 10972315Abstract: A signal estimator for an OFDM radio receiver is configured to generate a signal power estimate for a reference signal received on a subcarrier from a plurality of OFDM subcarriers. The signal estimator generates a first channel estimate as a first function of a first set of one or more unfiltered reference-signal channel estimates, where the first set includes an unfiltered reference-signal channel estimate. It generates a second channel estimate as a second function of a second set of one or more unfiltered reference-signal channel estimates, where the second set has no unfiltered reference-signal channel estimate in common with the first set. The signal estimator then generates the signal power estimate by multiplying the first channel estimate with the second channel estimate, such that the generated signal power estimate does not increase with the absolute square of any of the unfiltered reference-signal channel estimates in the first and second sets.Type: GrantFiled: October 25, 2018Date of Patent: April 6, 2021Assignee: Nordic Semiconductor ASAInventor: Mauri Nissilä
