US 12,772,272 B2 · User equipments and communication methods

Abstract

A user equipment (UE) is described. The UE may comprise control unit configured to select a RA type between a 4-step RA procedure and a 2-step RA procedure based on whether the UL BWP is further configured with RA resources used for the feature, wherein in a case that the UL BWP is configured with both a second 2-step RA type RA resources and a second 4-step RA type RA resources that are used for the feature, to select the RA type further based on a RSRP of downlink pathloss reference in a case that the UL BWP is not configured with the second 2-step RA type RA resources and the second 4-step RA type RA resources, to select the RA type further based on the RSRP, in a case that the UL BWP is configured with the second 4-step RA type RA resources and not configured with the second 2-step RA type RA resources, to select the 4-step RA procedure, and in a case that the UL BWP is configured with the second 2-step RA type RA resources and not configured with the second 4-step RA type RA resources, to select the 2-step RA procedure.

Dependent claims

A user equipment (UE), comprising:

reception circuitry configured to receive, from a base station, system information including a configuration for an UL BWP, wherein the UL BWP is configured with both first 2-step random access (RA) type RA resources and first 4-step RA type RA resources, and both the first 2-step RA type RA resources and the first 4-step RA type RA resources are not associated with a feature of Reduced Capabilities (RedCap);
and
control circuitry configured to select the UL BWP to perform a RA procedure, and to set a RA type of the RA procedure to one of a 4-step RA type and a 2-step RA type based on whether the UL BWP is further configured with second 2-step RA type RA resources and second 4-step RA type RA resources in addition to the first 2-step RA type RA resources and the first 4-step RA type RA resources, wherein both the second 2-step RA type RA resources and the second 4-step RA type RA resources are associated with the feature of RedCap.

A base station apparatus, comprising:

transmission circuitry configured to transmit, to a user equipment (UE), system information including a configuration for an UL BWP, wherein the UL BWP is configured with both first 2-step random access (RA) type RA resources and first 4-step RA type RA resources, and both the first 2-step RA type RA resources and the first 4-step RA type RA resources are not associated with a feature of Reduced Capabilities (RedCap);
and
control circuitry configured to cause the UE to select the UL BWP to perform a RA procedure, and to cause the UE to set a RA type of the RA procedure to one of a 4-step RA type and a 2-step RA type based on whether the UL BWP is further configured with second 2-step RA type RA resources and second 4-step RA type RA resources in addition to the first 2-step RA type RA resources and the first 4-step RA type RA resources, wherein both the second 2-step RA type RA resources and the second 4-step RA type RA resources are associated with the feature of RedCap.
