Handling intra user equipment uplink overlapping grants
One or more methods of handling intra user equipment (UE) uplink (UL) overlapping grants. At least one of the methods includes: configuring a logical channel (LC) with a parameter defining a reliability metric associated with the LC; determining, based on the parameter, that a grant satisfies a reliability requirement; and transmitting data associated with the LC using the grant.
1 . A method comprising:
receiving a logical channel (LC) parameter indicating a reliability requirement associated with the LC, wherein the reliability requirement comprises a spectrum efficiency (SE) limit of the LC, and wherein the SE limit corresponds to a row of a modulation and coding scheme (MCS) table;
determining that an SE of a first grant is less than or equal to the SE limit of the LC;
transmitting, using the first grant, data associated with the LC; and
refraining from using a second grant that overlaps with the first grant in response to determining that an SE of the second grant is above the SE limit of the LC.
2 . The method of claim 1 , wherein the first grant is a configured grant (CG) or a dynamic grant (DG).
3 . The method of claim 1 , wherein receiving the LC parameter indicating the reliability requirement associated with the LC comprises:
receiving the LC parameter in a logical channel configuration message.
4 . The method of claim 1 , wherein the LC parameter is indicative of an index in the MCS table.
5 . The method of claim 4 , further comprising:
receiving an indication of the MCS table in a Physical Uplink Shared Channel (PUSCH) configuration message.
6 . An apparatus comprising:
one or more processors; and
memory configured to store instructions that, when executed by the one or more processors, cause the apparatus to perform operations comprising:
receiving a logical channel (LC) parameter indicating a reliability requirement associated with the LC, wherein the reliability requirement comprises a spectrum efficiency (SE) limit of the LC, and wherein the SE limit corresponds to a row of a modulation and coding scheme (MCS) table,
determining that an SE of a first grant is less than or equal to the SE limit of the LC;
transmitting, using the first grant, data associated with the LC; and
refraining from using a second grant that overlaps with the first grant in response to determining that an SE of the second grant is above the SE limit of the LC.
7 . The apparatus of claim 6 , wherein the first grant is a configured grant (CG) or a dynamic grant (DG).
8 . The apparatus of claim 6 , wherein receiving the LC parameter indicating the reliability requirement associated with the LC comprises:
receiving the LC parameter in a logical channel configuration message.
9 . The apparatus of claim 6 , wherein the LC parameter is indicative of an index in the MCS table.
10 . The apparatus of claim 9 , the operations further comprising:
receiving an indication of the MCS table is in a Physical Uplink Shared Channel (PUSCH) configuration message.
11 . One or more processors configured to perform operations comprising:
receiving a logical channel (LC) parameter indicating a reliability requirement associated with the LC, wherein the reliability requirement comprises a spectrum efficiency (SE) limit of the LC, and wherein the SE limit corresponds to a row of a modulation and coding scheme (MCS) table;
determining that an SE of a first grant satisfies is less than or equal to the reliability requirement SE limit of the LC;
transmitting, using the first grant, data associated with the LC; and
refraining from using a second grant that overlaps with the first grant in response to determining that an SE of the second grant is above the SE limit of the LC.
12 . The one or more processors of claim 11 , wherein the first grant is a configured grant (CG) or a dynamic grant (DG).
13 . The one or more processors of claim 11 , wherein receiving the LC parameter indicating the reliability requirement associated with the LC comprises:
receiving the LC parameter in a logical channel configuration message.
14 . The one or more processors of claim 11 , wherein the LC parameter is indicative of an index in the MCS table.
15 . The one or more processors of claim 14 , the operations further comprising:
receiving an indication of the MCS table is in a Physical Uplink Shared Channel (PUSCH) configuration message.
