  • Patent number: 11432286
    Abstract: A base station is configured to transmit user data to a wireless device upon a first carrier. The base station identifies, from a set of transmission resources that is nominally allocated for transmission of user data upon the first carrier, a subset of transmission resources that is also nominally allocated for transmission of a reference or control signal either by the base station upon a second carrier or by a neighboring base station upon the first carrier. The base station selectively transmits user data to the wireless device upon the first carrier exclusive of this identified subset of transmission resources. The device in some embodiments obtains information indicating that the base station is selectively transmitting user data upon the first carrier exclusive of the subset in this way. Based on this information, the device recovers user data received upon the first carrier exclusive of the subset of transmission resources.

  • Patent number: 11425754
    Abstract: Embodiments herein relate to a method performed by a first communication node operating in a wireless communications network. The first communication node adjusts a value of a Contention Window, CW, from a first value to a second value, the second value being a higher value than the first value, wherein adjusting the value is based on: one or more feedback timers having expired at a time of performing a sensing procedure in the absence of: a) a received uplink, UL, grant from a second communication node, or b) a downlink feedback from the second communication node for an Autonomous Uplink, AUL, transmission from the first communication node. Following adjusting the value, the first communication node initiates a sensing procedure performed prior to a transmission of an UL burst to the second communication node, wherein the sensing procedure uses the adjusted value of the CW.
