Abstract

In wireless communication systems using a subband full duplex carrier, a single slot may include one or more uplink (UL) portions and/or one or more downlink (DL) portions. In a case where a scheduler operating in a 3GPP New Radio (NR) network utilizes a Type 0 or Type 1 resource allocation, part of the DL allocation may fall within the UL portion of the carrier designated by the slot format, or vice versa. User equipment (a UE) may perform a logical operation that identifies, as a usable downlink resource allocation, a set of resource blocks belonging to both a given UL/DL resource allocation and a set of resources designated for UL/DL transmission in the slot format.

Claims31

Dependent claims

A method of wireless communication operable by user equipment (a UE), comprising:

receiving, from a base station, information indicating a slot format configuration, the information identifying a first frequency portion of a slot and a second frequency portion of the slot, wherein one of the first or the second frequency portion of the slot is reserved for downlink communications and another of the first or the second frequency portion of the slot is reserved for uplink communications;
receiving, from the base station, a resource allocation for the slot that overlaps with at least a portion of the first frequency portion;
and
communicating, with the base station, over a set of usable resources that belongs to both the resource allocation and the first frequency portion, wherein the set of usable resources is based at least in part on the resource allocation and the slot format configuration, and
wherein communicating over the set of usable resources comprises either:
receiving a downlink communication over the set of usable resources, or transmitting an uplink communication over the set of usable resources.

3 more elements

A wireless communication device operable as user equipment (a UE), comprising:

one or more processors,
memory coupled to the one or more processors;
and
a transceiver coupled to the one or more processors;
wherein the one or more processors are configured to cause the UE to:
receive, from a base station, information indicating a slot format configuration the information identifying a first frequency portion of a slot and a second frequency portion of the slot, wherein one of the first or the second frequency portion of the slot is reserved for downlink communications and another of the first or the second frequency portion of the slot is reserved for uplink communications;
receive, from the base station, a resource allocation for the slot that overlaps with at least a portion of the first frequency portion;
and
communicate, with the base station, over a set of usable resources that belongs to both the resource allocation and the first frequency portion wherein the set of usable resources is based at least in part on the resource allocation and the slot format configuration, and
wherein communicating over the set of usable resources comprises either:
receiving a downlink communication over the set of usable resources, or transmitting an uplink communication over the set of usable resources.

8 more elements

A wireless communication device operable as user equipment (a UE), comprising:

means for receiving, from a base station, information indicating a slot format configuration, the information identifying a first frequency portion of a slot and a second frequency portion of the slot, wherein one of the first or the second frequency portion of the slot is reserved for downlink communications and another of the first or the second frequency portion of the slot is reserved for uplink communications;
means for receiving, from the base station, a resource allocation for the slot that overlaps with at least a portion of the first frequency portion;
and
means for communicating, with the base station, over a set of usable resources that belongs to both the resource allocation and the first frequency portion, wherein the set of usable resources is based at least in part on the resource allocation and the slot format configuration, and
wherein the means for communicating over the set of usable resources comprises either:
means for receiving a downlink communication over the set of usable resources, or means for transmitting an uplink communication over the set of usable resources.
