Network node, user equipment and methods performed therein in a wireless communications network

Embodiments herein relate to a method, performed by a network node (110) in a wireless communication system (100), for handling resource allocations for a first User Equipment, UE (120a) out of a set of UEs (120). Each of the UEs (120) in the set of UEs 5(120) has a different pre-configured frequency allocation for cyclic transmissions, such as cyclic UL and/or DL transmissions. The network node (110) determines, based on a data arrival pattern, such as e.g. a packet arrival time, of the cyclic UL transmissions for each of the UEs in the set of UEs (120), one or more TTIs, where a collision between transmissions to and/or from two UEs (120) out of the set of UEs (120) may occur. The 10 network node (110) reconfigures the frequency allocation for a first UE (120a) of the two UEs (120) to overlap, at least partly, with the frequency of a second UE (120b) of the two UEs (120) for the TTIs other than the TTIs where the collision between the transmissions to and/or from the first and the second UEs (120a, 120b) may occur. Embodiments herein further relate to a method, performed by the first UE (120a) out of the set of UEs (120) in 15 the wireless communication system (100), for handling resource allocation for the first UE (120a) out of the set of UEs (120).
