Abstract: Techniques for allocating cell site component capacity to conserve power are disclosed. Antenna ports of a radio unit are identified and a capacity for each antenna port is obtained. A throughput of a first antenna is obtained. A configuration for the first antenna is determined based on the throughput and the antenna port capacities. One or more antenna ports are selected, based on the capacities and the configuration for the first antenna, to allocate to the first antenna. The one or more antenna ports of the radio unit are then allocated to the first antenna. Antenna ports of the radio unit that are not allocated to the first antenna may be entered into a reduced-power state or allocated to a second antenna of the cell site.

Abstract: An interference mitigation system is provided herein. The interference mitigation system selects a threshold power range for signals received by at least one antenna and compares a power level of a signal to the threshold power range. Based on a determination of whether the power level of the first wireless signal exceeds the threshold power range, the interference mitigation system identifies nodes that transmit or receive wireless signals and causes the nodes to stop transmitting or receiving signals for a selected duration of time. The interference mitigation system receives additional signals during the selected duration of time, and determines whether the first wireless signal caused internal interference or external interference based on the additional signals and the first wireless signal. The interference mitigation system causes the interference to be resolved based on the determination of whether the interference is internal interference or external interference.

Abstract: An Open radio access network (ORAN) configured for accessing a 5G Core network to provide voice and data services to one or more mobile terminals, includes radio units (RUs), distributed units (DUs) and a centralized unit (CU) pool. The ORAN is configured such that each DU is configured to be associated concurrently to a primary CU and a secondary CU, both selected from the CU pool according to predetermined criteria. Upon occurrence of a predetermined event, the DU switches the secondary CU to become the primary CU, without resulting an outage in the ORAN.

Abstract: Techniques for criteria modification of wireless network infrastructure software package validation are provided. A NodeB includes a network entity that is a central unit, distributed unit or radio unit. A computer system receives data representing a pre-installation reference parameter determined when the network entity is operated using a first software package and receives data representing a post-installation reference parameter determined when the network entity is operated using a second software package. The computer system stores a criterion for validating the second software package, identifies a difference between the post-installation and pre-installation reference parameters, modifies the criterion based on the difference and determines whether to validate the second software package based on the modified criterion. If validated, the computer system, sends a signal to the NodeB indicating the validation, and the NodeB causes the second software package to be installed on the network entity.

Abstract: Techniques for dynamically transferring cell traffic to reduce power consumption are disclosed. A method for dynamically transferring cell traffic to reduce power consumption begins by determining a load on radio units that service a geographic area. A determination is made that the load on a first radio unit fails to satisfy a reduce power threshold. A determination is made that the load on the first radio unit satisfies a transfer threshold. The load on the first radio unit is transferred to at least a second radio unit such that the first radio unit satisfies the reduce power threshold. Then, a component associated with the first radio unit to turn off is selected. The component is turned off, causing the first radio unit to enter a reduced-power state.

Abstract: A method for selecting one or more antennas disposed at a base station BS of a wireless communication system, where the method includes: transmitting, to one or more use equipment (UE), one or more initial synchronization signal blocks (SSB) and one or more initial channel state information-reference signals (CSI-RS) using a plurality of antenna ports, receiving, from the one or more UE, signals including at least one parameter indicative of corresponding operating conditions at the one or more UE in response to the transmitted one or more initial SSB and CSI-RS, selecting one or more antenna ports among the plurality of antenna ports based on the received at least one parameter, and performing downlink transmission using the selected one or more antenna ports.

Abstract: Various arrangements for dynamically adjusting physical resource block (PRB) usage on a cellular network are presented. A primary entity may be determined to be exercising its priority to spectrum overlapping PRBs used by the cellular network. A frequency band being used by the primary entity based on measuring the signal strengths of wireless transmission by the primary entity can be determined. Subcarriers of the PRBs are identified that overlap the frequency band. A predefined Physical Random Access Channel (PRACH) format can be selected based at least in part on the identified subcarriers. A predefined Physical Uplink Control Channel (PUCCH) format can be selected based at least in part on the identified plurality of subcarriers.

Abstract: A method and apparatus for cell sleep state detection and recovery are provided. In the method and apparatus, one or more connection state criteria indicative of whether a cell is in a sleep state are evaluated to determine whether the one or more connection state criteria are met. The one or more connection state criteria are selected from a random access channel (RACH) criterion, a channel measurement criterion, a cell handover criterion, a connection statistics criterion, a connected user equipment criterion, or a measurement change criterion. It is determined whether the cell is in the sleep state based on whether at least one of the one or more connection state criteria are met and in response to determining that the cell is in the sleep state, action is taken to cause the cell to exit the sleep state.

Abstract: A method and apparatus for cell sleep state detection and recovery are provided. In the method and apparatus, an O-RAN network entity evaluates one or more resource utilization criteria indicative of whether a cell is in a sleep state to determine whether the one or more resource utilization criteria are met. The one or more resource utilization criteria are selected from a PUCCH criterion, a throughput criterion, a PRB utilization criterion, a PDCCH utilization criterion, a transmit or receive power criterion, a modulation and coding scheme criterion, a BLER criterion or a supplemental downlink criterion. The network entity determines whether the cell is in the sleep state based on whether at least one of the one or more resource utilization criteria are met and in response to determining that the cell is in a sleep state, causes the cell to exit the sleep state.
