  • Patent number: 10390334
    Abstract: 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.

  • Patent number: 10361821
    Abstract: In one aspect, a wireless device receives a first data transmission from a base station during a predetermined subframe interval and within a duration that is less than a maximum data transmission duration that is possible within the predetermined subframe interval, and determines a transmission time for transmitting HARQ feedback to the base station such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used for the first data transmission. The wireless device transmits HARQ feedback for the first data transmission at the determined transmission time. In another aspect, a base station transmits the first data transmission and determines a reception time for receiving HARQ feedback such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used. The base station receives HARQ feedback for the first data transmission at the determined transmission time.

  • Publication number: 20190215815
    Abstract: A method performed by a user equipment (UE) in idle mode, for determining common search space (CSS) for NB-IoT paging is disclosed. The method comprises determining a set of periodic subframes as a Paging Occasion (PO) subframe pattern. The method further comprises monitoring a starting subframe of paging CSS for a Radio Network Temporary Identifier (RNTI). The starting subframe of paging CSS is determined as follows: a first subframe (SF0) defined by the Paging Occasion subframe pattern, is used when SF0 is determined to be a valid downlink subframe. A next valid downlink subframe after SF0 is used when SF0 is determined to be an invalid downlink subframe.

  • Publication number: 20190053061
    Abstract: Embodiments herein relate for example to a method performed by a wireless device in a first wireless communication system that is deployed on a frequency resource. The wireless device receives information indicating a PRB offset and a corresponding channel raster offset. The channel raster offset is an offset in frequency between a channel raster, used by the wireless device (105) in a cell search process, and the frequency resource. The PRB offset indicates an offset between the frequency resource and an inner frequency resource on which a second wireless communication system is deployed. In the frequency domain, the second wireless communication system is deployed on at least one higher frequency resource above the inner frequency resource and at least one lower frequency resource below the inner frequency resource. The wireless device determines, based on the received information, an adjustment in frequency applicable for the frequency resource on which the first wireless communication system is deployed.
