NETWORK NODE, WIRELESS DEVICE AND METHODS THEREIN, FOR SCHEDULING ONE OR MORE BEARERS WITH DIFFERENT QOS REQUIREMENTS AND APPLYING A LISTEN-BEFORE-TALK SETTING, RESPECTIVELY

摘要

In the context of LTE License Assisted Access to a shared spectrum resource following a contention-based procedure, method performed by a network node (110) for scheduling one or more bearers for transmission to or from a wireless device (120). The wireless device (120) is serviced by the network node (110). The network node (110) calculates (1001) a weight for each bearer of the one or more bearers. The calculating (1001) is based on an indication of a quality of service associated with information to be transmitted in each bearer of the one or more bearers. The network node (110) schedules (1003) the one or more bearers for transmission to or from the wireless device (120) based on the calculated weight. The calculated weight corresponds to a Listen-Before-Talk, LBT, setting. The LBT setting comprises an LBT algorithm and its corresponding one or more parameters, such as initial CCA sensing time, extended CCA (eCCA) sensing time or range of random backoff number for extended Clear Channel Assessment, eCCA.
