Patent number: 11979224Abstract: Methods are disclosed which can be performed by a network node for sending to a wireless device a first synchronization signal and an associated information message, for synchronization of the wireless device with the network node. The network node and the wireless device operate in a wireless communications network. The network node sends the first synchronization signal in N OFDM symbols within a subframe, at least once in a time and frequency position in every one of the N OFDM symbols. N is equal or larger than 2. For each sending of the first synchronization signal, the network node sends an associated information message at a pre-defined time and frequency position in an OFDM symbol. The pre-defined time and frequency position is relative to the time and frequency position of the first synchronization signal. The associated information message is associated with the first synchronization signal.Type: GrantFiled: September 28, 2020Date of Patent: May 7, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mattias Frenne, Dirk Gerstenberger, Johan Furuskog

Patent number: 11956730Abstract: A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—?F_PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured.Type: GrantFiled: April 5, 2021Date of Patent: April 9, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Robert Baldemair, Jung-Fu Cheng, Dirk Gerstenberger, Daniel Chen Larsson

Uplink control information (UCI) mapping indicator for long term evolution (LTE) carrier aggregation
Patent number: 11838240Abstract: A system and method to instruct a user equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.Type: GrantFiled: May 25, 2021Date of Patent: December 5, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Dirk Gerstenberger, Daniel Larsson, David Hammarwall, Robert Baldemair -
Patent number: 11818719Abstract: Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits. The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.Type: GrantFiled: November 5, 2021Date of Patent: November 14, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Robert Baldemair, David Astely, Dirk Gerstenberger, Daniel Larsson, Stefan Parkvall

Patent number: 11818602Abstract: Power headroom reporting and report handling are discussed in the context of a Physical Uplink Shared Channel (PUSCH), on which a user equipment (UE) has no valid uplink grant, and a Physical Uplink Control Channel (PUCCH) on which a UE has no transmission. Under these circumstances, it is not possible to directly calculate one or more parameters which are used to calculate power headroom. Accordingly, exemplary embodiments provide for predetermined, known values to be used by the UE to calculate the power headroom, and by the eNodeB to understand the meaning of a received power headroom report.Type: GrantFiled: November 19, 2021Date of Patent: November 14, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Robert Baldemair, Dirk Gerstenberger, Daniel Larsson, Henning Wiemann

Publication number: 20220256541Abstract: A radio network node in a multi-carrier radio communication system reconfigures mappings of Carrier Indicator Field values (CIF-values) to component carriers. Each CIF-value is mapped to a respective component carrier comprising a respective shared data channel and a downlink control channel that addresses the shared data channel. The reconfiguring comprises maintaining a first mapping between a first CIF-value and a first component carrier. The downlink control channel of the first component carrier carries the first CIF-value and a second CIF-value. The reconfiguring further comprises changing a second mapping of the second CIF-value to a second component carrier. The radio network node sends the changed second mapping to a user equipment (UE) comprised in the multi-carrier radio communication system. The UE receives the reconfigured mappings and reconfigures the UE to use the mappings for communication in the multi-carrier radio communication system.Type: ApplicationFiled: April 27, 2022Publication date: August 11, 2022Inventors: Daniel Larsson, Robert Baldemair, Dirk Gerstenberger, Stefan Parkvall

Publication number: 20220078786Abstract: The present invention relates to methods and arrangements that make it possible to control the delay for the UEs to access the EUL resources in the Enhanced Uplink in CELL_FACH state procedure, independently from the delay for the UEs to access ordinary UL resources in the RACH procedure. This is achieved by a solution where the timing of entering (or re-entering) a transmission procedure for Enhanced Uplink in CELL_FACH state is controlled with the help of a transmission control parameter defined specifically for this transmission procedure, instead of using the same parameter as for the RACH procedure.Type: ApplicationFiled: November 19, 2021Publication date: March 10, 2022Inventors: Dirk GERSTENBERGER, Johan BERGMAN
