Uplink control information collision handling
Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to group transmissions into one or more groups, e.g., of various priority levels and/or types of transmissions. The UE may resolve collisions, e.g., according to one or more procedures described herein. The UE may transmit the transmissions according to the resolutions.
1 . A method comprising:
receiving an indication of a first priority level associated with a first type of physical uplink shared channel (PUSCH) transmission;
receiving an indication of a second priority level associated with a second type of PUSCH transmission, wherein the second priority level is lower than the first priority level;
receiving, via radio resource control (RRC) signaling, a first configured grant for a first PUSCH transmission of the first type of PUSCH transmission;
receiving, via RRC signaling, a second configured grant for a second PUSCH transmission of the second type of PUSCH transmission;
determining, based on the first configured grant and the second configured grant, that the first PUSCH transmission and the second PUSCH transmission overlap at least partially in the time domain; and
transmitting the first PUSCH transmission without transmitting at least a portion of the second PUSCH transmission.
2 . The method of claim 1 , wherein the second PUSCH transmission is not transmitted starting from a first symbol that the second PUSCH transmission is overlapped with the first PUSCH transmission.
3 . The method of claim 1 , wherein said determining is performed at a physical (PHY) layer.
4 . The method of claim 1 , wherein said determining is performed at a lower layer.
5 . The method of claim 1 , wherein the first configured grant comprises a first type of configured grant.
6 . The method of claim 5 , wherein the second configured grant comprises a second type of configured grant.
7 . The method of claim 1 , wherein the indication of the first priority level is received via higher layer signaling.
8 . An apparatus, comprising:
a processor configured to, when executing instructions stored in a memory, perform operations comprising:
decoding an indication of a first priority level associated with a first type of physical uplink shared channel (PUSCH) transmission;
decoding an indication of a second priority level associated with a second type of PUSCH transmission, wherein the second priority level is lower than the first priority level;
decoding a first configured grant for a first UL transmission of the first type of PUSCH transmission, wherein the first configured grant is received via radio resource control (RRC) signaling;
decoding a second configured grant for a second UL transmission of the second type of PUSCH transmission, wherein the second configured grant is received via RRC signaling;
determining, based on the first configured grant and the second configured grant, that the first PUSCH transmission and the second PUSCH transmission overlap at least partially in the time domain; and
encoding, for transmission, the first PUSCH transmission without encoding at least a portion of the second UL transmission.
9 . The apparatus of claim 8 , wherein the second PUSCH transmission is not transmitted starting from a first symbol that the second PUSCH transmission is overlapped with the first PUSCH transmission.
10 . The apparatus of claim 8 , wherein said determining is performed at a physical (PHY) layer.
11 . The apparatus of claim 8 , wherein said determining is performed at a lower layer.
12 . The apparatus of claim 8 , wherein the first configured grant comprises a first type of configured grant.
13 . The apparatus of claim 12 , wherein the second configured grant comprises a second type of configured grant.
14 . The apparatus of claim 8 , wherein the indication of the first priority level is received via radio resource control signaling.
15 . A method comprising:
transmitting, to a user equipment (UE), an indication of a first priority level associated with a first type of physical uplink shared channel (PUSCH) transmission;
transmitting, to the UE, an indication of a second priority level associated with a second type of UL transmission, wherein the second priority level is lower than the first priority level;
transmitting, to the UE via radio resource control (RRC) signaling, a first configured grant for a first PUSCH transmission of the first type of PUSCH transmission;
transmitting, to the UE via RRC signaling, a second configured grant for a second PUSCH transmission of the second type of PUSCH transmission, wherein the first configured grant and the second configured grant are useable for determining that the first PUSCH transmission and the second PUSCH transmission overlap at least partially in the time domain; and
receiving, from the UE, the first PUSCH transmission without at least a portion of the second PUSCH transmission.
16 . The method of claim 15 , wherein the second PUSCH transmission is not received starting from a first symbol that the second PUSCH transmission is overlapped with the first PUSCH transmission.
17 . The method of claim 15 , wherein the first configured grant comprises a first type of configured grant.
18 . The method of claim 17 , wherein the second configured grant comprises a second type of configured grant.
19 . The method of claim 18 , wherein the second type of configured grant is different from the first type of configured grant.
20 . The method of claim 15 , wherein the indication of the first priority level is transmitted via higher layer signaling.
