Abstract
The random access (RA) procedure in NR-U can be improved by enable the NR-U capable UE to choose a suitable BWP and uses this chosen BWP to perform the RA procedure. A suitable BWP is a BWP with a low probability for LBT failure, such as a BWP having a load that is less than a threshold load. For example, whenever the UE has a RA procedure triggered, the UE selects the most suitable BWP based on load information, such as load measurements made by the UE for one or more available BWPs or load information communicated to the UE. The selected BWP for the RA procedure may be different from the UE's currently active BWP, and, in this case, the UE may do a BWP switch before the RA procedure.

A method performed by a user equipment (UE), the method comprising:
- the UE receiving a message transmitted by a network node, wherein the message comprises bandwidth part (BWP) information comprising a first BWP load indicator for a first BWP, wherein the first BWP load indicator indicates a load status of the first BWP, wherein the first BWP is a first subset of contiguous common resource blocks, wherein the BWP information further comprises a second BWP load indicator for a second BWP, wherein the second BWP load indicator indicates a load status of the second BWP, wherein the second BWP is a second subset of contiguous common resource blocks, wherein the second subset does not overlap with the first subset;
- the UE obtaining the BWP information from the message;
- and
- the UE selecting a BWP from a set of BWPs comprising the first BWP and the second BWP based on the obtained BWP information.
A method performed by a network node, the method comprising:
- the network node transmitting a message comprising bandwidth part (BWP) information comprising a first BWP load indicator for a first BWP and a second BWP load indicator for a second BWP, wherein
- the first BWP is a first subset of contiguous common resource blocks,
- the second BWP is a second subset of contiguous common resource blocks, wherein the second subset does not overlap with the first subset,
- the first BWP load indicator indicates a load status of the first BWP, and
- the second BWP load indicator indicates a load status of the second BWP.
