Behavior of user equipment (UE) in scenarios of conflicting resource assignments in new radio (NR) systems
Embodiments of a User Equipment (UE) and methods of communication are generally described herein. If the UE is configured by higher layers to transmit, in a set of symbols of a slot, a sounding reference signal (SRS), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), or a physical random access channel (PRACH); and if a downlink control information (DCI) format indicates that the UE is to receive, in a subset of the set of symbols of the slot, channel state information reference signals (CSI-RS) or a physical downlink shared channel (PDSCH): the UE may: cancel transmission of the PUCCH, the PUSCH, or the PRACH in remaining symbols from the set of symbols; and may cancel transmission of the SRS in remaining symbols from the subset of symbols.
1. An apparatus of a User Equipment (UE) configured for operating in a Next-Generation Radio Access Network (NG-RAN), the apparatus comprising: memory; and processing circuitry coupled to the memory, wherein the processing circuitry is configured to:
decode radio-resource control (RRC) signalling that includes a TDD-UL-DL-ConfigurationCommon information element (IE);
set a slot format over a number of slots of based on the TDD-UL-DL-ConfigurationCommon IE, the slot format comprising downlink symbols, uplink symbols, and flexible symbols;
detect a downlink control information (DCI) granted multi-slot reception of a physical downlink shared channel (PDSCH) comprising multiple slots;
identify first slots of the multiple slots where the UE is scheduled for the PDSCH reception in which at least one symbol is indicated to be an uplink symbol based on the slot format; and
receive the PDSCH in the multiple slots other than the identified first slots,
wherein the memory is configured to store the slot format.
2. The apparatus of claim 1 wherein the processing circuitry is to configure the UE to refrain from receiving the PDSCH in the identified first slots.
3. The apparatus of claim 1 , wherein the processing circuitry is further configured to:
detect a DCI granted multi-slot transmission of a physical uplink shared channel (PUSCH) comprising multiple slots;
identify second slots of the multiple slots where the UE is scheduled for the PUSCH transmission in which at least one symbol is indicated to be a downlink symbol based on the slot format; and
encode the PUSCH for transmission in the multiple slots other than the identified second slots.
4. The apparatus of claim 3 wherein the processing circuitry is to configure the UE to refrain from transmitting the PUSCH in the identified second slots.
5. The apparatus of claim 1 , wherein the flexible symbols are to be either uplink symbols or downlink symbols based on a dynamic slot-format indicator (SFI).
6. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a User Equipment (UE) configured for operating in a Next-Generation Radio Access Network (NG-RAN), the processing circuitry configured to:
decode radio-resource control (RRC) signalling that includes a TDD-UL-DL-ConfigurationCommon information element (IE);
set a slot format over a number of slots of based on the TDD-UL-DL-ConfigurationCommon IE, the slot format comprising downlink symbols, uplink symbols, and flexible symbols;
detect a downlink control information (DCI) granted multi-slot reception of a physical downlink shared channel (PDSCH) comprising multiple slots;
identify first slots of the multiple slots where the UE is scheduled for the PDSCH reception in which at least one symbol is indicated to be an uplink symbol based on the slot format; and
receive the PDSCH in the multiple slots other than the identified first slots.
7. The non-transitory computer-readable storage medium of claim 6 wherein the processing circuitry is to configure the UE to refrain from receiving the PDSCH in the identified first slots.
8. The non-transitory computer-readable storage medium of claim 6 , wherein the processing circuitry is further configured to:
detect a DCI granted multi-slot transmission of a physical uplink shared channel (PUSCH) comprising multiple slots;
identify second slots of the multiple slots where the UE is scheduled for the PUSCH transmission in which at least one symbol is indicated to be a downlink symbol based on the slot format; and
encode the PUSCH for transmission in the multiple slots other than the identified second slots.
9. The non-transitory computer-readable storage medium of claim 8 wherein the processing circuitry is to configure the UE to refrain from transmitting the PUSCH in the identified second slots.
10. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a generation Node B (gNB) configured for operating in a Next-Generation Radio Access Network (NG-RAN), the processing circuitry configured to:
encode radio-resource control (RRC) signalling that includes a TDD-UL-DL-ConfigurationCommon information element (IE) for transmission to a user equipment (UE) to configure the UE with a slot format over a number of slots, the slot format comprising downlink symbols, uplink symbols, and flexible symbols;
encode a DCI granting a multi-slot transmission of a physical uplink shared channel (PUSCH) comprising multiple slots,
decode the PUSCH received from the UE, the PUSCH received in the multiple slots other than second slots, wherein the second slots comprise slots of the multiple slots where the UE is scheduled for the PUSCH transmission in which at least one symbol is indicated to be a downlink symbol based on the slot format.
11. An apparatus of a generation Node B (gNB) configured for operating in a Next-Generation Radio Access Network (NG-RAN), the apparatus comprising: processing circuitry; and memory, wherein the processing circuitry is configured to:
encode radio-resource control (RRC) signalling that includes a TDD-UL-DL-ConfigurationCommon information element (IE) for transmission to a user equipment (UE) to configure the UE with a slot format over a number of slots, the slot format comprising downlink symbols, uplink symbols, and flexible symbols;
encode a DCI granting a multi-slot transmission of a physical uplink shared channel (PUSCH) comprising multiple slots;
decode the PUSCH received from the UE, the PUSCH received in the multiple slots other than second slots, wherein the second slots comprise slots of the multiple slots where the UE is scheduled for the PUSCH transmission in which at least one symbol is indicated to be a downlink symbol based on the slot format; and
store the TDD-UL-DL-ConfigurationCommon IE in the memory.
