Abstract
Various embodiments herein provide techniques for frequency hopping for uplink transmission in advanced duplex systems, e.g., using non-overlapping sub-band full duplex (NOSB-FD) symbols. The frequency hopping may include switching between an NOSB-FD symbol and a non-NOSB-FD symbol. Embodiments further provide techniques for handling collision between uplink transmission and a downlink resource in the NOSB-FD symbol and/or non-NOSB-FD symbol. Other embodiments may be described and claimed.
Claims20
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors configure a user equipment (UE) to:
- receive scheduling or configuration information for transmission of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH) with frequency hopping that includes a switch between transmission in an uplink sub-band in a non-overlapping sub-band-full duplex (NOSB-FD) symbol and transmission in an active uplink bandwidth part (BWP) in a non-NOSB-FD symbol;
- and
- determine a starting physical resource block (PRB) for a frequency hop in the active uplink BWP or the uplink sub-band after the switch, wherein the determination of the starting PRB for the frequency hop is performed based on a frequency region corresponding to where a first symbol of the PUSCH or PUCCH is located in each hop.
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors configure a next generation Node B (gNB) to:
- encode, for transmission to a user equipment (UE), scheduling or configuration information for a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH) with frequency hopping that includes a switch between transmission in an uplink sub-band in a non-overlapping sub-band-full duplex (NOSB-FD) symbol and transmission in an active uplink bandwidth part (BWP) in a non-NOSB-FD symbol;
- determine a starting physical resource block (PRB) for a frequency hop in the active uplink BWP or the uplink sub-band after the switch, wherein the determination of the starting PRB for the frequency hop is performed based on a frequency region corresponding to where a first symbol of the PUSCH or PUCCH is located in each hop;
- and
- receive the PUSCH or PUCCH based on the determined starting PRB.
One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors configure a user equipment (UE) to:
- receive scheduling or configuration information for a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH) with frequency hopping that includes a switch between transmission in an uplink sub-band in a non-overlapping sub-band-full duplex (NOSB-FD) symbol and an active uplink bandwidth part (BWP) in a non-NOSB-FD symbol;
- identify that one or more physical resource blocks (PRBs) for a frequency hop of the PUSCH or PUCCH overlap with a downlink sub-band of the NOSB-FD symbol, or are not included in the uplink sub-band of the NOSB-FD symbol, or are not included in the uplink BWP;
- and
- cancel the frequency hop of the PUSCH or the PUCCH based on the identification, wherein a determination of a starting PRB for the frequency hop is performed based on a frequency region corresponding to where a first symbol of the PUSCH or PUCCH is located in each hop.
