Patent attributes
A wireless transmit/receive unit (WTRU) may receive configuration information for a first set of resources and a second set of resources for a grantless physical uplink shared channel (PUSCH) transmission. The WTRU may determine data for transmission using the grantless PUSCH transmission. Based on the data, the WTRU may select resources from the first set or the second set for the grantless PUSCH transmission. Further, the WTRU may send the grantless PUSCH transmission including the data using the selected resources. In an example, the sending of the grantless PUSCH transmission may be part of a random access procedure. The random access procedure may be a two-step random access procedure. The random access procedure may be a random access channel (RACH) procedure. The random access procedure may depend upon a double contention pool setting, and the setting may address at least one of a data pool or a control pool.
