Method for supporting standalone mtc operation using multi-narrowband
A recently granted patent (Publication Number: US11778536B2) describes a method and user equipment (UE) for supporting standalone machine type communication (MTC) operations using a multi-narrowband (NB) in a wireless communication system.
The method involves the UE receiving multi-NB configuration information from a base station. This configuration information pertains to a plurality of narrowbands defined in a next generation (NR) bandwidth, which includes a first system bandwidth for in-band MTC operations and a second system bandwidth for standalone MTC operations. The UE then performs frequency hopping on the plurality of NBs based on this configuration information, excluding the anchor-NB which represents the NB related to initial cell selection.
The first system bandwidth is specifically designed to support long term evolution (LTE) in-band operations for enhanced MTC (eMTC) systems. The second system bandwidth, on the other hand, supports standalone MTC operations for standard MTC (sMTC) systems. The UE also receives a system message from the base station containing eMTC barring information, which is related to supporting the eMTC UE. Based on this information, the UE can receive data from the base station in the LTE control region.
The user equipment (UE) described in the patent includes a transceiver, memory, and processor. The processor is configured to receive the multi-NB configuration information from the base station and perform frequency hopping on the plurality of NBs based on this information. Similar to the method, the UE excludes the anchor-NB from frequency hopping. The UE also receives the system message containing eMTC barring information and can receive data from the base station in the LTE control region based on this information.
The patent also mentions that the plurality of NBs can include one anchor-NB and one or more secondary-NBs. Additionally, the UE can receive control information for unused resource blocks (RBs) in the first system bandwidth from the base station. This control information is represented in a bitmap, with each bit of the bitmap related to each unused RB.
Overall, this patent presents a method and user equipment for supporting standalone MTC operations using a multi-NB in a wireless communication system. The method and UE allow for efficient frequency hopping and reception of data based on system configuration information and eMTC barring information.
