Abstract

Claims (38)

1 . A first network node for wireless communication, comprising:

at least one processor; and

a memory coupled to the at least one processor,

wherein the at least one processor is configured to:

receive resource allocation information including a quantity of bits that corresponds to a transmission bandwidth for a transmission, wherein the resource allocation information corresponds to a bitmap for resource element information of an active bandwidth part (BWP), wherein the BWP is a downlink (DL) BWP, an uplink (UL) BWP, or an UL/DL BWP, wherein each bit of the bitmap corresponds to a respective resource block group (RBG) of the active BWP, wherein a particular RBG for a particular bit of the bitmap partially overlaps with a transmission band for the transmission, and wherein the particular RBG is not allocated or transmitted; and

communicate, based on the quantity of bits, with a second network node using the transmission bandwidth for the transmission.

2 . A first network node for wireless communication, comprising:

at least one processor; and

a memory coupled to the at least one processor,

wherein the at least one processor is configured to:

receive resource allocation information including a quantity of bits that corresponds to a transmission bandwidth for a transmission, wherein the resource allocation information corresponds to a bitmap for resource element information of an active bandwidth part (BWP), wherein the BWP is a downlink (DL) BWP, an uplink (UL) BWP, or an UL/DL BWP, wherein each bit of the bitmap corresponds to a respective RBG of the active BWP, wherein a particular RBG for a particular bit of the bitmap partially overlaps with a transmission band for the transmission, wherein a first portion of the corresponding RBG is allocated and transmitted and a second portion of the corresponding RBG is not allocated or transmitted, and wherein the first portion corresponds to resource blocks of the particular RBG which fully overlap the transmission band; and

communicate, based on the quantity of bits, with a second network node using the transmission bandwidth for the transmission.

3 . A first network node for wireless communication, comprising:

at least one processor; and

a memory coupled to the at least one processor,

wherein the at least one processor is configured to:

receive resource allocation information including a quantity of bits that corresponds to a transmission bandwidth for a transmission; and

communicate, based on the quantity of bits, with a second network node using the transmission bandwidth for the transmission, wherein the quantity of bits corresponds to a total quantity bits of a frequency domain resource allocation (FDRA) field, and wherein the total quantity of bits is based on:

a quantity of resource block groups that overlap one or more

corresponding subbands of a slot of the transmission, and an RBG size.

4 . The first network node of claim 3 , wherein the RBG size indicates a quantity of RBs in each RBG, and wherein the total quantity of bits in the FDRA field is the quantity of RBGs that at least partially overlap with any of the subbands divided by the quantity of RBs in each RBG.

5 . A first network node for wireless communication, comprising:

at least one processor; and

a memory coupled to the at least one processor,

wherein the at least one processor is configured to:

receive resource allocation information including a quantity of bits that corresponds to a transmission bandwidth for a transmission; anmd

communicate, based on the quantity of bits, with a second network node using the transmission bandwidth for the transmission, wherein a band corresponding to the transmission has multiple subbands, wherein a first subband of the multiple subbands has a first RBG size and a second subband of the multiple subbands has a second RBG size different from the first RBG size, and wherein a total number of bits of the transmission is a sum a first quantity of bits that corresponds to a first quantity of RBGs in a BWP overlapping with the first subband divided by the first RBG size of the first subband and of a second quantity of bits that corresponds to a second quantity of RBGs in the BWP overlapping with the second subband divided by the second RBG size of the second subband.

6 . A first network node for wireless communication, comprising:

at least one processor; and

a memory coupled to the at least one processor,

wherein the at least one processor is configured to:

receive resource allocation information including a quantity of bits that corresponds to a transmission bandwidth for a transmission;

receive slot type information and resource element size information;

determine a length of an FDRA field based on the slot type information and the resource element size information, wherein the resource allocation information corresponds to the FDRA field;

determine the transmission bandwidth for the transmission based on the length of the FDRA field; and

communicate, based on the quantity of bits, with a second network node using the transmission bandwidth for the transmission.

7 . The first network node of claim 6 , wherein, to determine the transmission bandwidth based on the length of the FDRA field, the at least one processor is configured to:

determine the transmission bandwidth for the transmission based on a quantity of bits of the FDRA field which have a particular value.
