RATE MATCHING FOR MULTI-SLOT UPLINK SHARED CHANNEL TRANSMISSION
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more sets of contiguous time domain resources for a multi-slot transmission occasion that spans at least multiple slots. The UE may select, for one or more codeblocks of a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis for each of the multiple slots, wherein start locations for bit selection for each of the multiple slots are determined independently from one another. The UE may interleave the coded bits to form one or more interleaved encoded bit sequences of the one or more codeblocks. The UE may transmit the communication including the one or more interleaved encoded bit sequences. Numerous other aspects are described.
1 . An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, individually or collectively configured to cause the UE to:
receive an indication of one or more sets of time domain resources for a multi-slot transmission occasion that spans multiple slots;
select, for one or more codeblocks of a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis for each of the multiple slots, wherein start locations for bit selection for the multiple slots are irrespective of whether uplink control information is multiplexed;
interleave, for each of the multiple slots, the coded bits to form one or more interleaved encoded bit sequences of the one or more codeblocks; and
transmit the communication including the one or more interleaved encoded bit sequences.
2 . The apparatus of claim 1 , wherein the indication is received via downlink control information.
3 . The apparatus of claim 1 , wherein the start locations for bit selection for the multiple slots are indicated by a redundancy version index.
4 . The apparatus of claim 1 , wherein the coded bits are selected using a particular redundancy version (RV) across the multiple slots, wherein the multiple slots comprise an RV bundle.
5 . The apparatus of claim 4 , wherein the particular RV is indicated by an RV table that includes a sequence of RVs for the UE to use in different RV bundles.
6 . The apparatus of claim 1 , wherein a start location of a given slot of the multiple slots is independent of an end location of a prior slot of the multiple slots.
7 . The apparatus of claim 1 , wherein the start locations for bit selection for the multiple slots are determined prior to selecting the coded bits.
8 . The apparatus of claim 1 , wherein the coded bits are selected from a circular buffer.
9 . A method of wireless communication performed by a user equipment (UE), comprising:
receiving an indication of one or more sets of time domain resources for a multi-slot transmission occasion that spans multiple slots;
selecting, for one or more codeblocks of a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis for each of the multiple slots, wherein start locations for bit selection for the multiple slots are irrespective of whether uplink control information is multiplexed;
interleaving, for each of the multiple slots, the coded bits to form one or more interleaved encoded bit sequences of the one or more codeblocks; and
transmitting the communication including the one or more interleaved encoded bit sequences.
10 . The method of claim 9 , wherein the indication is received via downlink control information.
11 . The method of claim 9 , wherein the start locations for bit selection for the multiple slots are indicated by a redundancy version index.
12 . The method of claim 9 , wherein the coded bits are selected using a particular redundancy version (RV) across the multiple slots, wherein the multiple slots comprise an RV bundle.
13 . The method of claim 12 , wherein the particular RV is indicated by an RV table that includes a sequence of RVs for the UE to use in different RV bundles.
14 . The method of claim 9 , wherein a start location of a given slot of the multiple slots is independent of an end location of a prior slot of the multiple slots.
15 . The method of claim 9 , wherein the start locations for bit selection for the multiple slots are determined prior to selecting the coded bits.
16 . The method of claim 9 , wherein the coded bits are selected from a circular buffer.
17 . A non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
receive an indication of one or more sets of time domain resources for a multi-slot transmission occasion that spans multiple slots;
select, for one or more codeblocks of a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis for each of the multiple slots, wherein start locations for bit selection for the multiple slots are irrespective of whether uplink control information is multiplexed;
interleave, for each of the multiple slots, the coded bits to form one or more interleaved encoded bit sequences of the one or more codeblocks; and
transmit the communication including the one or more interleaved encoded bit sequences.
18 . The non-transitory computer-readable medium of claim 17 , wherein the indication is received via downlink control information.
19 . The non-transitory computer-readable medium of claim 17 , wherein the start locations for bit selection for the multiple slots are indicated by a redundancy version index.
20 . The non-transitory computer-readable medium of claim 17 , wherein the coded bits are selected using a particular redundancy version (RV) across the multiple slots, wherein the multiple slots comprise an RV bundle.
