Abstract: Techniques described herein include solutions for enabling user equipment (UEs) to report UE capability information based on deployed channel bandwidths (BWs) in each radio frequency (RF) band used by a base station. During an attached procedure, a base station may UE capability information from a UE and receive requested frequency band information (RFB) in response thereto. The RFB information (e.g., UE capability information) may be based on a comparison of an actual maximum BW for all possible CA combinations for the base station and Ω—a maximum aggregate BW supported by the UE. The UE may report the RFB to the base station for the CA combinations with a maximum BW that is less than or equal to Ω. After reporting, the UE may proceed with the attach procedure. Additional and alternative features and techniques are also described.

Abstract: The techniques described herein include superior home-on-home roaming procedures by enabling user equipment (UE) to modify a home public land mobile network (HPLMN) search periodicity based on a likelihood of detecting an HPLMN cell (e.g., base station). A UE may be configured to determine a current geographic location of the UE, access a database that includes information about the HPLMN for the location (e.g., prior HPLMN searches), determine an appropriate HPLMN search periodicity based on the information, and perform HPLMN searches based on the appropriate HPLMN search periodicity. In some implementations, the UE may determine the HPLMN search periodicity based on a number (N) of HPLMN cells, and/or times an HPLMN cell sample, associated with the geographic area, has been detected previously.
