Managing uplink access of ues to a wireless network
A recently filed patent (Publication Number: US20230319702A1) describes a method for managing access of User Equipments (UEs) to a wireless network using unlicensed spectrum. The method involves transmitting a reference signal by a cell of the wireless network, which includes one or more bits indicating the presence or absence of uplink access constraints determined by the cell. The cell then connects to a UE based on the reference signal.
The patent also mentions that the reference signal can be broadcasted, including a first set of bits used by UEs to determine the level of downlink interference corresponding to the cell, and a second set of bits indicating the uplink access constraints. The reference signal can be a synchronization signal, with reserve bits serving as undesignated bits of the synchronization signal.
In addition, the patent suggests broadcasting multiple reference signals in different spatial directions, with the values of the bits in each reference signal indicating the presence or absence of uplink access constraints in the respective spatial direction.
The uplink access constraints can be related to the threshold distance of UEs from the cell or the uplink interference detected by the cell in different spatial directions. The threshold distance can be predefined.
The method also includes detecting the level of uplink interference in a spatial direction, determining if it exceeds an interference threshold, and setting the values of the bits in the reference signal accordingly. The reference signal is then transmitted in the corresponding spatial direction.
Furthermore, the patent mentions that the connection between the cell and the UE is established when the UE selects the cell as a serving cell based on the reference signal.
The patent also describes a cell site of a wireless network configured to manage access to the network using unlicensed spectrum. The cell site includes one or more transceivers for transmitting the reference signal and connecting to UEs based on the reference signal.
Overall, this patent proposes a method and system for managing access to a wireless network using unlicensed spectrum, allowing for efficient and reliable connectivity for User Equipments.
