Methods and apparatuses for improved voice coverage
Methods and apparatus are described herein for improved efficiency of a wireless transmit/receive unit (WTRU) transmitting transport blocks (TBs). A WTRU may receive configuration information including uplink resources associated with one or more repetition bundles and a target number of retransmissions for a transport block (TB) associated with at least one hybrid automatic repeat request (HARQ) process. Then, the WTRU may transmit a first TB using a first uplink resource in a first repetition bundle based on the configuration information. Further, the WTRU may increment a retransmission counter. On a condition that the retransmission counter is less than the target number of retransmissions, the WTRU may determine a second uplink resource. Further, the WTRU may retransmit the first TB in the determined second uplink resource. Also, the WTRU may further increment the retransmission counter. Moreover, the first, second and third uplink resources may be physical uplink shared channel (PUSCH) resources.
1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
receiving configuration information including uplink resources associated with one or more repetition bundles and a target number of transmissions for a transport block (TB) associated with at least one hybrid automatic repeat request (HARQ) process;
transmitting a first TB using a first uplink resource in a first repetition bundle based on the configuration information;
incrementing a transmission counter;
on a condition that the transmission counter is less than the target number of transmissions, determining a second uplink resource;
transmitting the first TB in the determined second uplink resource;
further incrementing the transmission counter; and
on a condition that the transmission counter is greater than or equal to the target number of transmissions:
resetting the transmission counter;
toggling a new data indicator (NDI);
determining a third uplink resource; and
transmitting a second TB in the determined third uplink resource.
2. The method of claim 1 , wherein the determined second uplink resource is in one of: the last slot in a repetition bundle, the first repetition bundle, or a second repetition bundle.
3. The method of claim 1 , wherein the first uplink resource, the determined second uplink resource and the determined third uplink resource are physical uplink shared channel (PUSCH) resources.
4. The method of claim 1 , wherein the first uplink resource, the determined second uplink resource and the determined third uplink resource are configured grant (CG) resources.
