Handling overlapping of PUCCH and PUSCH for new radio systems
Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) to operate in a New Radio (NR) system comprises one or more baseband processors to determine if two or more uplink signals partially overlap, determine a multiplexing rule, a dropping rule, or a priority rule for the two or more uplink signals, and to multiplex, drop, or prioritize the two or more uplink signals for transmission according to the multiplexing rule, dropping rule, or priority rule, and a memory to store two or more uplink signals.
1. An apparatus of a user equipment (UE) to operate in a New Radio (NR) network, comprising:
radio frequency (RF) circuitry configured to communicate with the NR network; and
one or more baseband processors communicatively coupled to the RF circuitry and configured to perform operations, comprising:
determining if two or more uplink signals overlap;
determining a rule for transmitting the two or more uplink signals and to perform a transmission according to the rule; and
appending X number of bits to one of the two or more uplink signals indicating a scheduling request (SR) state when i) the two or more uplink signals comprise a physical uplink control channel (PUCCH) format 2, 3, or 4, ii) the two or more uplink signals comprise a PUCCH format 0 or 1, iii) the PUCCH format 2, 3, or 4 is configured to carry one or more of a hybrid automatic repeat request acknowledgment (HARQ-ACK) and a channel state information (CSI) and iv) the PUCCH format 2, 3, or 4 overlaps with a number of configured SR transmission occasions.
2. The apparatus of claim 1 , wherein the rule indicates that the UE is to transmit only one of the two or more uplink signals while other uplink signals are dropped.
3. The apparatus of claim 1 , wherein the rule indicates that the UE is to drop a scheduling request (SR) and transmit a hybrid automatic repeat request acknowledgment (HARQ-ACK) on a physical uplink control channel (PUCCH) when the two or more uplink signals comprise i) a PUCCH format 1 carrying HARQ-ACK and ii) a PUCCH format 0 or 1 configured for SR.
4. The apparatus of claim 1 , wherein the rule indicates that the UE is to transmit only one PUCCH signal and drop other PUCCH signals.
5. The apparatus of claim 1 , wherein the rule indicates that the UE is to drop a physical uplink control channel (PUCCH) signal carrying a channel state information (CSI) report.
6. An apparatus of a user equipment (UE) to operate in a New Radio (NR) network, comprising:
radio frequency (RF) circuitry configured to communicate with the NR network; and
one or more baseband processors are communicatively coupled to the RF circuitry and configured to perform operations, comprising:
determining if two or more uplink signals overlap;
determining a rule for transmitting the two or more uplink signals and to perform a transmission according to the rule; and
multiplexing a scheduling request (SR) on a hybrid automatic repeat request acknowledgment (HARQ-ACK) carrying physical uplink control channel (PUCCH) and generating a sequence for transmission with a cyclic shift of the HARQ-ACK when i) the two or more uplink signals comprise a PUCCH format 0 carrying HARQ-ACK and ii) the two or more uplink signals comprise a PUCCH format 0 or 1 configured for SR.
7. The apparatus of claim 6 , wherein the rule indicates that the UE is to transmit only one of the two or more uplink signals while other uplink signals are dropped.
8. The apparatus of claim 6 , wherein the rule indicates that the UE is to drop a scheduling request (SR) and transmit a hybrid automatic repeat request acknowledgment (HARQ-ACK) on a physical uplink control channel (PUCCH) when the two or more uplink signals comprise i) a PUCCH format 1 carrying HARQ-ACK and ii) a PUCCH format 0 or 1 configured for SR.
9. The apparatus of claim 6 , wherein the rule indicates that the UE is to transmit only one PUCCH signal and drop other PUCCH signals.
10. The apparatus of claim 6 , wherein the rule indicates that the UE is to drop a physical uplink control channel (PUCCH) signal carrying a channel state information (CSI) report.
