Abstract
Systems and methods are disclosed that relate to management of uplink (UL) transmissions in unlicensed spectrum. In some embodiments, a method of operation of a network node in a wireless communication network comprises signaling, to a wireless device, an indication of one or more allocated sets of Resource Blocks (RBs) that are allocated to the wireless device by a UL grant for transmission on a UL carrier in an unlicensed frequency spectrum. The one or more allocated sets of RBs are one or more of a plurality of defined sets of RBs that correspond to a plurality of interlaces, respectively, that each spread out across an entire bandwidth of the UL carrier. In this manner, higher UL user and system performance can be obtained.
