Abstract
Among other things, some embodiments of the present disclosure are directed to coverage enhancement techniques for the physical uplink control channel (PUCCH). Specifically, the PUCCH may be transmitted from two or more antenna ports of a user equipment (UE) based on configuration information received from a base station. Other embodiments may be disclosed and/or claimed.
Claims19
An apparatus comprising:
- memory to store multiple antenna port (AP) transmission mode configuration information for a physical uplink control channel (PUCCH);
- and
- processor circuitry, coupled with the memory, to:
- retrieve the multiple AP transmission mode configuration information from the memory, wherein the AP transmission mode configuration information includes an indication of an allocation of resources to two or more APs of a user equipment (UE) for transmission of the PUCCH;
- and
- encode a message for transmission to the UE that includes the multiple AP transmission mode configuration information;
- wherein the multiple AP transmission mode configuration information is to cause the UE to:
- transmit the PUCCH by a first AP of the two or more APs in a set of time domain resources of a slot and at a first frequency domain resource with a first starting physical resource block (PRB) index;
- transmit the PUCCH by a second AP of the two or more APs in the set of time domain resources of the slot and at a second frequency domain resource with a second starting PRB index;
- and
- wherein a frequency distance between the first starting PRB index and the second starting PRB index is half of an initial or active bandwidth part (BWP) bandwidth related to the PUCCH transmission.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, are to cause a next-generation NodeB (gNB) to:
- determine multiple antenna port (AP) transmission mode configuration information for a physical uplink control channel (PUCCH), wherein the multiple AP transmission mode configuration information includes an indication of an allocation of resources to two or more antenna ports (APs) of a user equipment (UE) for transmission of the PUCCH;
- and
- encode a message for transmission to the UE via radio resource control (RRC) signaling that includes the multiple AP transmission mode configuration information;
- wherein the multiple AP transmission mode configuration information is to cause the UE to:
- transmit, from a first AP of the two or more APs, the PUCCH on a set of time domain resources and a first frequency domain resource;
- transmit, from the first AP, the PUCCH on the set of time domain resources and a second frequency domain resource;
- and
- transmit, from a second AP of the two or more APs, the PUCCH on the set of time domain resources and at a third frequency domain resource that is between the first and second frequency domain resources in the frequency domain.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, are to cause a user equipment (UE) to:
- identify, received from a base station, multiple antenna port (AP) transmission mode configuration information for a physical uplink control channel (PUCCH), wherein the multiple AP transmission mode configuration information includes an indication of an allocation of resources to two or more antenna ports (APs) of the UE for transmission of the PUCCH;
- transmit the PUCCH by a first AP of the two or more APs in a set of time domain resources of a slot and at a first frequency domain resource with a first starting physical resource block (PRB) index;
- transmit the PUCCH by a second AP of the two or more APs in the set of time domain resources of the slot and at a second frequency domain resource with a second starting PRB index;
- and
- wherein a frequency distance between the first starting PRB index and the second starting PRB index is half of an initial or active bandwidth part (BWP) bandwidth related to the PUCCH transmission.
