NETWORK NODES, A WIRELESS DEVICE AND METHODS THEREIN FOR ENABLING TRANSMISSIONS IN A WIRELESS COMMUNICATIONS NETWORK

摘要

Embodiments herein relate to a method performed by a first network node (110) for enabling at least one second network node (111) to perform a transmission in a wireless communications network (100). The first network node (110) and the at least one second network node (111) performs transmissions using contention-based transmission resources of the same frequency. The first network node (110) determines an indication of a maximum transmit power for the transmission by the at least one second network node (111) to be used by the at least one second network node (111) when the contention- based transmission resources of the same frequency is available for transmissions by the first network node (110) in the wireless communications network (100). Then, the network node (110) transmits the determined indication of a maximum transmit power to the at least one second network node (111). Embodiments of the first network node (110) are also described. Embodiments herein also relate to a method performed by a second network node (111) for performing a transmission in a wireless communications network (100),and embodiments of the second network node (111). Embodiments herein further relate to a method performed by a first wireless device (121) for enabling a second network node (111) in a wireless communications network (100) to perform a transmission to the first wireless device (121), and embodiments of the first wireless device (121).
