Patent number: 11121803Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines a first uplink slot on an uplink carrier for reporting channel state information. The UE determines, on a downlink carrier, a first downlink slot that is an earliest downlink slot overlaps with the first uplink slot. The UE determines a number M based on a numerology of the downlink carrier, M being an integer greater than or equal to 0. The UE measures a reference signal, received no later than a second downlink slot that is a latest valid downlink slot no later than M downlink slots prior to the first downlink slot, to generate the channel state information.Type: GrantFiled: May 9, 2019Date of Patent: September 14, 2021Assignee: MEDIATEK INC.Inventors: Teemu Tapio Virtanen, Weidong Yang, Karl Marko Juhani Lampinen, Lung-Sheng Tsai

Patent number: 11026075Abstract: Apparatuses and methods provide for scheduling downlink control information in a wireless network. The apparatuses and methods may determine at least one control message for a user equipment and a downlink grant to be scheduled, and schedule transmission of one of the at least one control message with the downlink grant to precede transmission of related data on a downlink data channel. The apparatuses and methods may alternatively schedule a control message other than downlink grant for a user equipment, determine a downlink grant to be scheduled, and schedule a control message with the downlink grant to end last among all control messages in a search space. The apparatuses and methods may further alternatively schedule control messages for a user equipment, including one control message with a downlink grant and scheduled to end at the same time as or a later time than other control messages in a search space.Type: GrantFiled: March 27, 2020Date of Patent: June 1, 2021Assignee: SPREADTRUM HONG KONG LIMITEDInventors: Karl Marko Juhani Lampinen, Arto Johannes Lehti

Publication number: 20150173087Abstract: A method, apparatus and computer program product are provided to suppress interference, such as interference attributable to increased network density, interference attributable to interference between uplink and downlink transmissions in a TDD system and/or interference attributable to D2D communications. In the context of a method, it is determined whether communication between an access point and a mobile terminal or between a mobile terminal and another mobile terminal is to be subjected to real-valued modulation or complex-valued modulation such that the modulation and a dominant form of interference for the mobile terminal are either both real-valued or both complex-valued. The method also includes providing for communication with the mobile terminal in accordance with the one of real-valued modulation or complex-valued modulation that was determined.Type: ApplicationFiled: May 30, 2013Publication date: June 18, 2015Applicant: BROADCOM CORPORATIONInventors: Karl Marko Juhani Lampinen, Tommi Koivisto, Mihai Horatiu Enescu, Timo Eric Roman, Maja Loncar, Lars Christensen, Soeren Skovgaard Christensen

Publication number: 20150094112Abstract: A user equipment (UE) determines a first transmission power for a control channel using closed loop power control with a wireless network; and determines a second transmission power for the control channel. For transmission time intervals (TTIs) in which the UE is transmitting the control channel and also transmitting data on a data channel, the UE selects the second transmission power for transmitting the control channel. For TTIs in which the UE is transmitting the control channel but not also transmitting data on the data channel, the UE selects the first transmission power for transmitting the control channel. Three distinct embodiments are shown for these two transmission powers, and also quantitative data is shown that in a HSPA system this technique reduces inter-user interference at least at high SINR.Type: ApplicationFiled: September 27, 2013Publication date: April 2, 2015Applicant: Renesas Mobile CorporationInventors: Karl Marko Juhani LAMPINEN, Arto Johannes LEHTI, Tao CHEN, Tuomas Tapio HILTUNEN

Publication number: 20150092669Abstract: In a heterogeneous network environment where both high and low power nodes are sharing the same channel/frequency, explicit signaling in a downlink control message is used to select whether scheduling information SI is to be transmitted by a user equipment UE with a data payload or without a data payload. For the case where the selection is that SI is to be transmitted with a data payload, the downlink control message is used for the UE to select a transport format combination TFC for transmission of the SI with the data payload. Else for the case where the selection is that SI is to be transmitted without a data payload, the downlink control message is used for the UE to select transmit power for the transmission of the SI without the data payload.Type: ApplicationFiled: September 27, 2013Publication date: April 2, 2015Applicant: Broadcom CorporationInventors: Tao CHEN, Arto Johannes LEHTI, Karl Marko Juhani LAMPINEN, Christopher CALLENDER, Ilmari REPO

The method includes receiving a power grant corresponding to the allowed transmission power on the shared uplink wireless communication channel. Also, the user equipment receives a scheduling grant corresponding to whether transmission is allowed on the shared uplink wireless communication channel. The user equipment transmits data on the shared uplink wireless communication channel according to the power grant and the scheduling grant, wherein the power grant is received separately from the scheduling grant. A corresponding method of controlling transmission, apparatus and computer program product is also described.Type: ApplicationFiled: June 12, 2014Publication date: December 18, 2014Inventors: Karl Marko Juhani LAMPINEN, Arto Johannes LEHTI, Tao CHEN
