Abstract

A wireless device is configured with a first configured grant associated with a first hybrid automatic repeat request (HARQ) pool and a second configured grant associated with a second HARQ pool. The first HARQ pool at least partially overlaps with the second HARQ pool, and the second configured grant partially overlaps with the first configured grant. For the first configured grant, the wireless device selects a first HARQ process from the first HARQ pool. For the second configured grant, the wireless device selects a second HARQ process from the second HARQ pool. The first HARQ process selected for the first configured grant is different than the second HARQ process selected for the second configured grant. The wireless device performs uplink transmission or retransmission for the first configured grant or the second configured grant.

Dependent claims

A method performed by a wireless device, wherein the wireless device is configured with a first configured grant associated with a first hybrid automatic repeat request (HARQ) pool and a second configured grant associated with a second HARQ pool, and wherein the first HARQ pool at least partially overlaps with the second HARQ pool, and wherein the second configured grant partially overlaps with the first configured grant, the method comprising:

for the first configured grant, selecting a first HARQ process from the first HARQ pool,
for the second configured grant, selecting a second HARQ process from the second HARQ pool, wherein the first HARQ process selected for the first configured grant is different than the second HARQ process selected for the second configured grant;
and
transmitting on an uplink (UL) for the first configured grant or the second configured grant, and
wherein when selecting the first HARQ process for the first configured grant and the second HARQ process for the second configured grant, the method further comprises:
determining whether there is a retransmission in an overlapping portion of the first HARQ pool and the second HARQ pool,
wherein, when there is the retransmission in the overlapping portion of the first HARQ pool and the second HARQ pool, a selected HARQ process is for the retransmission and is from the overlapping portion of the first HARQ pool and the second HARQ pool, and
wherein, when there is no retransmission in the overlapping portion of the first HARQ pool and the second HARQ pool, the first HARQ process for the first configured grant and the second HARQ process for the second configured grant are from a non-overlapping of the first HARQ pool and the second HARQ pool.

A wireless device configured with a first configured grant associated with a first hybrid automatic repeat request (HARQ) pool and a second configured grant associated with a second HARQ pool, wherein the first HARQ pool at least partially overlaps with the second HARQ pool, wherein the second configured grant partially overlaps with the first configured grant, the wireless device comprising:

a memory storing instructions;
and
a processor operable to execute the instructions to cause the wireless device to:
for the first configured grant, select a first HARQ process from the first HARQ pool,
for the second configured grant, select a second HARQ process from the second HARQ pool, wherein the first HARQ process selected for the first configured grant is different than the second HARQ process selected for the second configured grant;
and
transmit on an uplink (UL) for the first configured grant or the second configured grant, and
wherein when selecting the first HARQ process for the first configured grant and the second HARQ process for the second configured grant, the wireless device is operable to:
determine whether there is a retransmission in an overlapping portion of the first HARQ pool and the second HARQ pool,
wherein, when there is the retransmission in the overlapping portion of the first HARQ pool and the second HARQ pool, a selected HARQ process is for the retransmission and is from the overlapping portion of the first HARQ pool and the second HARQ pool, and
wherein, when there is no retransmission in the overlapping portion of the first HARQ pool and the second HARQ pool, the first HARQ process for the first configured grant and the second HARQ process for the second configured grant are from a non-overlapping of the first HARQ pool and the second HARQ pool.
