1. A method comprising:
receiving, by a user equipment (UE), a resource configuration from a base station for a plurality of transmissions without dynamic grant, wherein the resource configuration defines K resources for K transmissions, wherein the K transmissions are for a transport block (TB) carrying data, and wherein the K resources correspond to a same hybrid automatic repeat request (HARQ) process identifier (ID) for the plurality of transmissions, the plurality of transmissions including an initial transmission of the TB and at least one up to K−1 retransmissions of the TB, K being an integer greater than or equal to 2;
transmitting, by the UE, the initial transmission of the TB without dynamic grant of the TB using a non-first resource among the K resources that is at a later time than a beginning resource of the K resources; and
transmitting, by the UE, a retransmission of the TB using a next available resource of the K resources,
wherein the K resources are in K consecutive slots, the retransmission is a first retransmission of the TB, and the next available resource is in a next immediate available slot of the K consecutive slots to a slot of the non-first resource, and
wherein the same HARQ process ID is determined based on an index of a time location of the non-first resource, a periodicity, and a configured maximum number of HARQ processes.
