Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify, using a reliability sequence associated with a plurality of modulation orders and a subblock allocation sequence associated with a single modulation order of the plurality of modulation orders, an allocation of one or more information bits among one or more polar channel subblocks. The wireless communication device may transmit, in accordance with the single modulation order, the one or more information bits using the allocation of the one or more information bits among the one or more polar channel subblocks. Numerous other aspects are described.

Claims (54)

1 . An apparatus for wireless communication at a wireless communication device, comprising:

one or more non-transitory memories; and

one or more processors, coupled to the one or more non-transitory memories, configured to cause the wireless communication device to:

identify, using a reliability sequence associated with a plurality of modulation orders and a subblock allocation sequence associated with a single modulation order of the plurality of modulation orders, an allocation of one or more information bits among one or more polar channel subblocks; and

transmit, in accordance with the single modulation order, the one or more information bits using the allocation of the one or more information bits among the one or more polar channel subblocks.

2 . The apparatus of claim 1 , wherein the one or more processors are further configured to cause the wireless communication device to:

select the subblock allocation sequence based at least in part on the single modulation order.

3 . The apparatus of claim 1 , wherein the one or more processors, to cause the wireless communication device to identify the allocation of the one or more information bits among the one or more polar channel subblocks, are configured to cause the wireless communication device to:

discard one or more elements of the subblock allocation sequence based at least in part on a target length associated with the subblock allocation sequence.

4 . The apparatus of claim 1 , wherein the one or more processors, to cause the wireless communication device to identify the allocation of the one or more information bits among the one or more polar channel subblocks, are configured to cause the wireless communication device to:

identify one or more elements of the subblock allocation sequence based at least in part on a quantity of the one or more information bits; and

identify a quantity of occurrences of one or more values of the one or more elements.

5 . The apparatus of claim 1 , wherein the one or more processors, to cause the wireless communication device to identify the allocation of the one or more information bits among the one or more polar channel subblocks, are configured to cause the wireless communication device to:

discard one or more elements of the reliability sequence based at least in part on a target length associated with the reliability sequence; and

identify the allocation of the one or more information bits among the one or more polar channel subblocks based at least in part on the target length associated with the reliability sequence.

6 . The apparatus of claim 1 , wherein the one or more processors are further configured to cause the wireless communication device to:

puncture or shorten, for each polar channel subblock of the one or more polar channel subblocks, a plurality of polar-coded bits.

7 . The apparatus of claim 6 , wherein the one or more processors are further configured to cause the wireless communication device to:

partition, for each polar channel subblock of the one or more polar channel subblocks, the plurality of polar-coded bits; and

permute, for each polar channel subblock of the one or more polar channel subblocks, the plurality of polar-coded bits.

8 . A method of wireless communication performed by a wireless communication device, comprising:

identifying, using a reliability sequence associated with a plurality of modulation orders and a subblock allocation sequence associated with a single modulation order of the plurality of modulation orders, an allocation of one or more information bits among one or more polar channel subblocks; and

transmitting, in accordance with the single modulation order, the one or more information bits using the allocation of the one or more information bits among the one or more polar channel subblocks.

9 . The method of claim 8 , further comprising:

selecting the subblock allocation sequence based at least in part on the single modulation order.

10 . The method of claim 8 , wherein identifying the allocation of the one or more information bits among the one or more polar channel subblocks includes:

discarding one or more elements of the subblock allocation sequence based at least in part on a target length associated with the subblock allocation sequence.

11 . The method of claim 8 , wherein identifying the allocation of the one or more information bits among the one or more polar channel subblocks includes:

identifying one or more elements of the subblock allocation sequence based at least in part on a quantity of the one or more information bits; and

identifying a quantity of occurrences of one or more values of the one or more elements.

12 . The method of claim 8 , wherein identifying the allocation of the one or more information bits among the one or more polar channel subblocks includes:

discarding one or more elements of the reliability sequence based at least in part on a target length associated with the reliability sequence; and
