CN-116058058-B - Base station, method and non-transitory computer readable storage medium limiting access to reduced capability user equipment

Abstract

A base station may restrict access of a User Equipment (UE). The base station broadcasts access restrictions to one or more UEs within the cell coverage area of the base station, wherein the access restrictions include one or more predetermined criteria that must be met in order for the UE to be allowed to camp on the base station. When the UE meets the one or more predetermined criteria, the base station performs a Random Access Channel (RACH) procedure to allow the UE to camp on the base station.

Description

Base station, method and non-transitory computer readable storage medium limiting access to reduced capability user equipment Background The 5G new air interface (NR) wireless communications support a number of different types of User Equipment (UE). For example, in addition to mobile phones, 5G NR supports internet of things (IoT) devices, industrial IoT (IIoT) devices, wearable devices, and the like. Some of these devices are referred to as reduced capability (RedCap) UEs that have varying wireless capabilities compared to other UEs. There may be situations where the network wants to treat RedCap UE differently than other types of UEs. Disclosure of Invention Some example embodiments relate to a base station having a processor and a transceiver communicatively coupled to the processor. The processor is configured to perform operations. The operations include broadcasting an access restriction to one or more User Equipments (UEs) within a cell coverage area of a base station, wherein the access restriction includes one or more predetermined criteria that must be met in order to allow the UE to camp on the base station, and performing a Random Access Channel (RACH) procedure to allow the UE to camp on the base station when the UE meets the one or more predetermined criteria. Other exemplary embodiments relate to a method performed by a base station of a wireless network. The method includes broadcasting an access restriction to one or more User Equipments (UEs) within a cell coverage area of a base station, wherein the access restriction includes one or more predetermined criteria that must be met in order to allow the UE to camp on the base station, and performing a Random Access Channel (RACH) procedure to allow the UE to camp on the base station when the UE meets the one or more predetermined criteria. Further exemplary embodiments relate to a baseband processor configured to perform operations. The operations include broadcasting an access restriction to one or more User Equipments (UEs) within a cell coverage area of a base station, wherein the access restriction includes one or more predetermined criteria that must be met in order to allow the UE to camp on the base station, and performing a Random Access Channel (RACH) procedure to allow the UE to camp on the base station when the UE meets the one or more predetermined criteria. Drawings Fig. 1 illustrates an exemplary network arrangement according to various exemplary embodiments. Fig. 2 illustrates an exemplary UE in accordance with various exemplary embodiments. Fig. 3 illustrates an example base station configured to establish a connection with a user equipment in accordance with various example embodiments. Fig. 4 is a signaling diagram illustrating a registration process in accordance with various exemplary embodiments. Detailed Description The exemplary embodiments may be further understood with reference to the following description and the appended drawings, wherein like elements have the same reference numerals. The exemplary embodiments describe devices, systems, and methods for a 5G new air interface (NR) network to limit access to the network by certain types of User Equipment (UEs). The exemplary embodiments are described with reference to a network comprising a 5G new air interface NR Radio Access Technology (RAT). However, the exemplary embodiments may be implemented in other types of networks using the principles described herein. Exemplary embodiments are also described with reference to a UE. However, the use of the UE is for illustration purposes only. The exemplary embodiments can be utilized with any electronic component that can establish a connection with a network and that is configured with hardware, software, and/or firmware for exchanging information and data with the network. Thus, the UE described herein is used to represent any electronic component. As described above, there are various UEs, each having different capabilities to connect to the 5G NR network. However, in a given area, it may not be beneficial to have different UEs with different capabilities camp on the same cell, as the reduced capability UEs may utilize different parameters (e.g., bandwidth portion, data rate, etc.) for wireless communication than other UEs (e.g., mobile phones, laptops, etc.), meaning that the cell will need to customize its communication for all types of UEs. Thus, there may be situations where the network wants to treat reduced capability (RedCap) UEs differently than other types of UEs. Before describing exemplary embodiments, redCap UE and several examples of their characteristics will be described. In a first example, a device in an industrial environment, such as a temperature or humidity sensor, may be a connected industrial device. However, such devices are fixed, not delay critical, and are completely uncomplicated with respect to their capabilities and hardware. These devices typically do not require low-latency data exchang
