1. A method for allocation of contention-based data transmission (CBDT) resource blocks in a non-terrestrial network (NTN), comprising:
determining, by a network, that the CBDT resource blocks are to be configured for allocation to a plurality of user equipments (UEs) based on two or more of a plurality of parameters including a UE traffic model, latency, quality of service (QOS) requirements, processing capability at a gnodeB (gNB), and a load at the gnodeB (gNB);
determining, by the network, that a fixed number of CBDT resource blocks from the CBDT resource blocks determined to be used for the allocation to the plurality of UEs based on at least one of the plurality of parameters; and
allocating, by the network, a number of CBDT resource blocks in one of a fixed manner or a dynamic manner, wherein the number of CBDT resource blocks are allocated in the fixed manner based on the fixed numbers of CBDT resource blocks being used for the allocation to the plurality of UEs, and the number of CBDT resource blocks are allocated in the dynamic manner based on the fixed numbers of CBDT resource blocks not being used for the allocation to the plurality of UEs,
wherein allocating the number of CBDT resource blocks in the fixed manner comprises calculating the number of CBDT resource blocks based on a type of application used by each of the plurality of UEs and a ratio of acknowledgement/non-acknowledgement (ACK/NACK) of previously allocated resource blocks to the plurality of UEs.
