A wireless data system receives first user data for a first user application. The wireless data system receives second user data for a second user application. The wireless data system processes the first user data with a first set of functions based on the first user application. The wireless data system processes the second user data with a second set of the functions based on the second user application. The functions comprise Physical Layer (PHY), Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC). The first set of the functions differs from the second set of the functions.

Dynamic wireless network architecture to serve uplink-centric and downlink-centric user applications

Systems and methods are provided for dynamic power allocation of a first maximum uplink power and a second maximum uplink power, wherein the first maximum uplink power is used by a first transmitter to communicate with a first access point and the second maximum uplink power is used by a second transmitter to communicate with a second access point (dual connectivity). Network parameters are determined based on characteristics and/or qualities of the downlink and/or uplink signals of a wireless communication session. In response to the determined network parameters, the WCD may increase a first maximum uplink power and decrease a second maximum uplink power in order to establish or maintain dual connectivity without exceeding the device's maximum total uplink power.

Dual connectivity (DC) power control

In a wireless data network, a Distributed Unit (DU) receives Uplink (UL) server data from server applications in wireless User Equipment (UEs). The DU processes the UL server data with an UL DU Hybrid Automatic Repeat Request (HARQ), generates UL HARQ Acknowledgements (ACKs) based on the UL server data, and transfers the UL server data to a Central Unit (CU). The CU receives the UL server data, processes the UL server data with an UL CU MAC, and transfers the UL server data. The CU receives (Downlink) DL server data for the server applications in the wireless UEs and transfers the DL server data to the DU. The DU receives the DL server data from the CU, processes the DL server data with a DL DU MAC comprising a DL DU HARQ, and transfers the DL server data and the UL HARQ ACKs to the wireless UEs.

Assigning carriers to radio ports communicably coupled to a corresponding plurality of antennae of a radio head, wherein the radio head is split into at least first and second split portions, determining a difference between a first power level available to the first carrier via the first set of radio ports and a second power level available to the second carrier via the second set of radio ports, and changing a split of the radio head such that the difference between the first and second power levels is minimized.

Assigning carriers to radio ports of a split radio head

In a wireless network, a Distributed Unit (DU) receives Uplink (UL) data from User Equipment (UE) and a Central Unit (CU) receives Downlink (DL) data for the UE. When DL-centric applications in the UE use the DL, the CU executes most network applications and the DU executes a few network applications. When the DL-centric applications use the UL, the DU executes the network applications and the CU transfers the UL data to the core. When UL-centric applications in the UE use the DL, the CU routes the DL data to the DU, and the DU executes the network applications. When the UL-centric applications use the UL, the DU executes a few network applications and the CU executes most network applications to route the data to the core. Advantageously, the DU and the CU are optimized to process UL/DL data for a user application based on whether the user application is UL-centric or DL-centric.

Systems, methods, and processing nodes are configured to perform scheduling in a wireless network utilizing a multi-user multiple-input multiple-output (MU-MIMO) operating mode, by determining that a throughput indicator of a sector meets a threshold, and adjusting a time window during which a first one or more wireless devices are removed from a MU-MIMO group and a second one or more wireless devices are added to the MU-MIMO group. The first one or more wireless devices comprise any wireless device that has a throughput below a threshold, and the second one or more wireless devices comprise any wireless device that has not been in the MU-MIMO group for a predefined time period.

Systems and methods for dynamically selecting a sub-carrier spacing

A computer-implemented method, system, and computer-readable storage media for scheduling physical resource blocks (PRBs) comprises a communication radio access network (RAN) base station with a scheduler that assigns one or more PRBs to a communication channel of a user device. The PRBs can be prioritized according to a radio frequency (rf) interference level across the contiguous band of PRBs. The rf interference level of a communication channel of the user device can be monitored by the scheduler. The scheduler assigns one or more of the prioritized PRBs according to the rf interference level of the PRBs and according to the rf interference level of the communication channel of the user device.

Long term evolution scheduler to mitigate interference

A computer-implemented method, system, and computer-readable storage media for mitigating interference in a communication system is described. A user equipment operating near an edge of its base station coverage cell may transmit a strong uplink signal, which can interfere with a nearby base station. When a serving base station recognizes a high downlink signal from a nearby base station, an interference mitigation algorithm is enabled by the serving base station. The interference mitigation algorithm of the serving base station will control the uplink signal from the user equipment, so the user equipment does not interfere with the nearby base station.

A scheduling module is selected from among a plurality of scheduling modules based on the frequency band identifier, and transmission of the data is scheduled to the wireless using the selected scheduling module.
