BBU3900 Huawei In the realm of mobile telecommunications, LTE FDD base stations are the critical infrastructure components that enable wireless connectivityRemote radio unit (rru) and base band unit (bbu) A fundamental aspect of configuring and maintaining these base stations is the precise understanding of BBU slot assignmentFor a 5 MHz band in 4GLTE, the frame is split into subframes, each consisting of twoslots. Everyslotcontains a number of OFDM symbols, and  The BBU, or Baseband Unit, is the brain of the base station, housing essential processing and management functionsHUAWEI BBU5900(3GPP) 5G DBS5900 Distributed Base Effectively assigning slots within the BBU is paramount for optimizing performance, ensuring flexibility, and managing hardware resources efficientlyBuilding Baseband Unit. • Provide the physical interface between thebase stationand the core network. • Provide the interface to RRU.

The architecture of modern LTE base stations, particularly those employing the distributed BBU + RRU (Remote Radio Unit) model, necessitates robust BBU slot assignment strategiesThis section describes the principles forBBU slot assignmentin LNbase stations. The following table describes the principles forBBU slot assignment. Table 5  This approach decouples the baseband processing from the radio frequency units, allowing for greater deployment flexibility and easier upgradesSevenLTE-TDD radiobase stations(BS) at 2.3-2.4 GHz have been installed both indoor (5 Femto BSs) and outdoor (2 Macro BSs) in the building of the Italian  When configuring a BBU, such as the widely used Huawei BBU3900 or the more advanced BBU5900, understanding the principles of slot assignment is crucialTheBBU+MERC mode supportsBBUaccess for UMTS,LTE FDD,LTE For details, see theslot assignmentprinciples for theBBUinbase stationsin different modes. These principles ensure that different functional boards, ranging from processing units to interface modules, are allocated to their designated slots for optimal operationBTS3900C (Ver.C) - Hardware Description

The BBU slot assignment in LTE FDD/LTE TDD Base Stations is guided by established methodologies designed to accommodate various network configurations and technological evolutions, including FDD LTEYou can consider the entirebase stationas one logic device, withBBUand FSW acting as interface cards in differentslotsof this logic device.

These assignments are not arbitrary; they are based on the functional requirements of each board and the overall system architectureBBU Slot Assignment in LTE FDD/LTE TDD Base StationsThis section describes the principles for BBU3910 slot assignment in LTE FDD and LTE TDD base stations. The same principles often extend to other models like the DBS3900 and DBS5900, which also support LTE FDD and can be configured in different modes, such as BBU+MERCDBS5900 Distributed Base Stations The BBU slot assignment for an LTE NB-IoT base station, for example, can be identical to that of an LTE FDD base station, highlighting a degree of standardization2013527—Table 3-3Slot assignmentprinciples for the boards in the BBU3900LTE Figure 7-15 CPRI cable connections in the GSM+LTE base station.

The concept of slot assignment extends beyond just the physical placement of boardsEquipment in LTE network In the context of LTE's physical layer, a slot itself is a fundamental time division within a subframeThe DBS5900 adopts a modular structure, with the baseband unitBBUand remote radio unit RRU deployed separately. (FDD),LTE FDD,NRFDD,GLM,GL,LM. TX/RX Channel  For a 5 MHz band in 4G LTE, a frame is divided into subframes, and each subframe comprises two slotsTheBBU+MERC mode supportsBBUaccess for UMTS,LTE FDD,LTE For details, see theslot assignmentprinciples for theBBUinbase stationsin different modes. Each of these slots contains a specific number of OFDM symbolsChapter 6 - 5G and beyond networks The location of critical resources, like the PUCCH (Physical Uplink Control Channel) resource block within the second slot, often mirrors the location of a corresponding resource block in the first slot, demonstrating a structured approach to resource allocation at the symbol and slot level (AMS) 215.
