Abstract

Apparatus, methods, and computer program products for full duplex communication are provided. An example method may include receiving a FDRA indication from a network entity, where the FDRA indication allocates a set of scheduling resources in a first band of a DL band or a UL band and includes an indication associated with a resource utilization in a second band of the UL band or the DL band, and where the DL band and the UL band overlap in a time domain. The example method may include receiving, from the network entity, a RRC configuration associated with a guard band between the UL band and the DL band. The example method may include communicating, with the network entity, a UL transmission or a DL transmission based on at least one of the set of scheduling resources, the guard band, or the resource utilization in the second band.

First claim

What is claimed is:

1 . An apparatus for wireless communication at a user equipment (UE), comprising:
a memory; and at least one processor coupled to the memory, wherein the at least one processor is configured to:
receive a frequency domain resource allocation (FDRA) indication from a network entity, wherein the FDRA indication allocates a set of scheduling resources in a first band of a downlink (DL) band or an uplink (UL) band, wherein the FDRA indication comprises an indication associated with a resource utilization in a second band of the UL band or the DL band, and wherein the DL band and the UL band overlap in a time domain;
receive, from the network entity, a radio resource control (RRC) configuration associated with a guard band between the UL band and the DL band; and
communicate, with the network entity, a UL transmission or a DL transmission based on at least one of the set of scheduling resources, the guard band, or the resource utilization in the second band.

2 . The apparatus of claim 1 , wherein the at least one processor is configured to:
calculate a length of the guard band between the UL band and the DL band; and apply a filtering based on the RRC configuration associated with the guard band and the resource utilization in the second band.

3 . The apparatus of claim 1 , wherein the at least one processor is configured to:
perform a cross link interference (CLI) measurement in the second band based on the resource utilization; and transmit a result of the CLI measurement to the network entity.

4 . The apparatus of claim 1 , wherein the set of scheduling resources comprises one or more resource blocks (RBs) that are non-continuous in a frequency domain.

5 . The apparatus of claim 1 , wherein the FDRA indication represents the set of scheduling resources in the first band in a first bitmap, and wherein the FDRA indication represents the resource utilization in the second band in a second bitmap.

6 . The apparatus of claim 1 , wherein the FDRA indication represents the set of scheduling resources in the first band in a bitmap, and wherein the FDRA indication represents the resource utilization in the second band in the bitmap.

7 . An apparatus for wireless communication at a network entity, comprising:
a memory; and at least one processor coupled to the memory, wherein the at least one processor is configured to:
transmit a frequency domain resource allocation (FDRA) indication for a user equipment (UE), wherein the FDRA indication allocates a set of scheduling resources in a first band of a downlink (DL) band or an uplink (UL) band, wherein the FDRA indication comprises an indication associated with a resource utilization in a second band of the UL band or the DL band, and wherein the DL band and the UL band overlap in a time domain;
transmit a radio resource control (RRC) configuration associated with a guard band between the UL band and the DL band; and
communicate, with the UE, a UL transmission or a DL transmission based on at least one of the set of scheduling resources, the guard band, or the resource utilization in the second band.

8 . The apparatus of claim 7 , wherein the guard band is based on the RRC configuration and the resource utilization in the second band.

9 . The apparatus of claim 7 , wherein the at least one processor is configured to:
receive a result of a cross link interference (CLI) measurement in the second band based on the resource utilization.

10 . The apparatus of claim 7 , wherein the set of scheduling resources comprises one or more resource blocks (RBs) that are non-continuous in a frequency domain.

11 . The apparatus of claim 7 , wherein the FDRA indication represents the set of scheduling resources in the first band in a first bitmap, and wherein the FDRA indication represents the resource utilization in the second band in a second bitmap.

12 . The apparatus of claim 7 , wherein the FDRA indication represents the set of scheduling resources in the first band in a bitmap, and wherein the FDRA indication represents the resource utilization in the second band in the bitmap.

13 . A method of wireless communication at a user equipment (UE), comprising:
receiving a frequency domain resource allocation (FDRA) indication from a network entity, wherein the FDRA indication allocates a set of scheduling resources in a first band of a downlink (DL) band or an uplink (UL) band, wherein the FDRA indication comprises an indication associated with a resource utilization in a second band of the UL band or the DL band, and wherein the DL band and the UL band overlap in a time domain; receiving, from the network entity, a radio resource control (RRC) configuration associated with a guard band between the UL band and the DL band; and communicating, with the network entity, a UL transmission or a DL transmission based on at least one of the set of scheduling resources, the guard band, or the resource utilization in the second band.

14 . The method of claim 13 , further comprising:
calculating a length of the guard band between the UL band and the DL band; and applying a filtering based on the RRC configuration associated with the guard band and the resource utilization in the second band.

15 . The method of claim 13 , further comprising:
performing a cross link interference (CLI) measurement in the second band based on the resource utilization; and transmitting a result of the CLI measurement to the network entity.

16 . The method of claim 13 , wherein the set of scheduling resources comprises one or more resource blocks (RBs) that are non-continuous in a frequency domain.

17 . The method of claim 13 , wherein the FDRA indication represents the set of scheduling resources in the first band in a first bitmap, and wherein the FDRA indication represents the resource utilization in the second band in a second bitmap.

18 . The method of claim 13 , wherein the FDRA indication represents the set of scheduling resources in the first band in a bitmap, and wherein the FDRA indication represents the resource utilization in the second band in the bitmap.

19 . A method of wireless communication at a network entity, comprising:
transmitting a frequency domain resource allocation (FDRA) indication for a user equipment (UE), wherein the FDRA indication allocates a set of scheduling resources in a first band of a downlink (DL) band or an uplink (UL) band, wherein the FDRA indication comprises an indication associated with a resource utilization in a second band of the UL band or the DL band, and wherein the DL band and the UL band overlap in a time domain; transmitting a radio resource control (RRC) configuration associated with a guard band between the UL band and the DL band; and communicating, with the UE, a UL transmission or a DL transmission based on at least one of the set of scheduling resources, the guard band, or the resource utilization in the second band.

20 . The method of claim 19 , wherein the guard band is based on the RRC configuration and the resource utilization in the second band.
