摘要： A method of operating a wireless cellular communication system includes: operating one of an eNB or gNB communicating with a set of user equipments (UEs); and scheduling, using a scheduler, uplink (UL) auto-grants to the set of the UEs when selected resources are available, the selected resources including Physical Downlink Control Channel (PDCCH) resource, Physical Uplink Shared Channel (PUSCH) resource and scheduler capacity. The scheduler determines at least two UEs in RRC-connected mode and having zero UL buffer count, at least one of the two UEs with downlink (DL) traffic present and at least one of the two UEs without DL traffic present. The scheduler selects a set of RRC-connected UEs with zero UL buffer count for which UL auto-grants can be scheduled with a designated number of physical resource blocks (PRBs) and designated Modulation and Coding Scheme (MCS).

摘要： Minimizing signaling traffic between a User Plane (UP) and a Control Plane (CP), where Policy and Charging Function/Policy and Charging Rule Function (PCF/PCRF) software transmits a first and a second Policy and Charging Control rule (PCCRule1 and PCCRule2) to CP equipment. The CP equipment installs both PCCRule1 and PCCRule2 on UP equipment as UPRule1 and UPRule2 respectively, where UPRule1 is set as active during a first time period and the UPRule2 set as active during a second time period. User Plane Function (UPF) software matching data traffic with a Packet Detection Rule (PDR) to generate identified traffic during the first and second time periods and automatically redirecting data traffic to a predetermined location at the expiration of the first and second time periods respectively. UPRule1 and UPRule2 are automatically enabled and disabled alternatively after expiration of their respective timers by the UPF software.

摘要： A control plane signaling method for reducing energy consumption of O-RAN radio units used in O-RAN CUS and including an O-DU controlling an O-RU via control-plane messaging where a sleep period is extended using a 16-bit binary number that is formed by two reserved octets in Section Type 0, or via an inactivity timer is used to trigger transitions between different sleep states and active states, or via and a bitmap is formed by a reserved octet in Section Type 0 and is used to signal the O-RU to directly transition to different sleep modes.

摘要： An method for expediting Virtual Local Area Network (VLAN) scanning for Dynamic Host Configuration Protocol (DHCP) server includes: transmitting, by a software tool, VLAN ethernet trunk frames including VLAN Identifier (ID) 1 to VLAN ID 4095, to an ethernet interface of a radio unit (RU), the ethernet interface being connected via an ethernet switch to a distributed unit (DU), wherein the DHCP server is located at the DU; selectively forwarding, by the ethernet switch to the DU, only a VLAN ethernet trunk frame having VLAN ID value X predefined by operator of the O-RAN system; selectively responding, by the DU, in response to receiving the VLAN ethernet trunk frame having VLAN ID value X, by sending a DHCP response message to the RU; and identifying, by the RU from the DHCP response message, the VLAN ID value X corresponding to the DHCP server.

摘要： A method of optimizing traffic steering (TS) radio resource management (RRM) decisions for handover of individual user equipment (UE) in Open Radio Access Network (O-RAN) includes: providing an O-RAN-compliant near real time RAN intelligent controller (near-RT RIC) configured to interact with O-RAN nodes; and utilizing an artificial intelligence (AO-based TS application xApp in the near-RT RIC to optimize TS handover control and maximize UE throughput utility. The TS xApp is configured utilizing a virtualized and simulated environment for O-RAN, which virtualized and simulated environment for O-RAN is provided by ns-O-RAN platform. The optimization problem to be solved is formulated as a Markov Decision Process (MDP), and a solution to the optimization problem is derived by using at least one reinforcement learning (RL) technique.

摘要： A method of processing multiple consecutive Narrowband Internet of Things (NBIOT) cells by a Radio Access Network (RAN) of a mobile network includes one of: a)1) shifting at least one first NBIOT cell relative to an adjacent second NBIOT cell to align all sub carriers of the first and second NBIOT cells to be mutually orthogonal; and a)2) using a first single fast Fourier transform (FFT) or first single inverse fast Fourier transform (iFFT) by the RAN to process both the first and second NBIOT cells; or b1) for a sequence of NBIOT cells, every third NBIOT cell is grouped into a single group, wherein all sub carriers of the NBIOT cells in the single group are mutually orthogonal; and b2) using the first single FFT or the first single iFFT by the RAN to process multiple NBIOT cells in the single group formed from the every third NBIOT cell.

摘要： A system and method of operating an Open Radio Access Network (O-RAN, in which O-RAN the system includes: a baseband unit (BBU) having an O-RAN centralized unit (O-CU) and an O-RAN distributed unit (O-DU); an O-RAN radio unit (O-RU) remote from the BBU; and a fronthaul interface between the O-RU and the BBU. A functional split of O-RAN functions respectively assigned to O-RU and O-DU for the fronthaul interface between the BBU and the O-RU is different for downlink (DL) and uplink (UL) so that at least one of i) demodulation reference signal (DM-RS)-based channel estimation is performed by the O-DU in the DL and by the O-RU in the UL, ii) equalization is performed by the O-DU in the DL and by the O-RU in the UL, and iii) demodulation is performed by the O-DU in the DL and by the O-RU in the UL.

摘要： A method of optimizing Overload Control Information (OCI) handling for a Control Plane (CP) that has a first association with a first User Plane (UP 1) and a second association with a second User Plane (UP 2) includes: upon receiving from UP 1 an OCI containing i) overload reduction metric defining a target number of sessions for the first association, and ii) a specified period of validity for the OCI handling, initiating a timer for the period of validity for the OCI handling; periodically checking the number of sessions currently being handled by the first association; initiating new sessions with UP 1 if the number of sessions currently being handled by the first association is below the target number of sessions; and not initiating new sessions with the UP 1 if the number of sessions currently being handled by the first association is above the target number of sessions.
