Abstract

A method performed by a Distributed Unit (DU) (1202) for handling communications in a wireless communication network (1). The DU (1202) configures (803) a Radio Unit (RU) (1203) for one static endpoint mapped to two or more non-static endpoints. Each non-static endpoint has a defined logical path between a DU (1202) and RU (1203) for transmitting data of the data stream of the one static endpoint.

Description

Distributed unit, radio unit and method performed therein Technical Field Embodiments herein relate to a Distributed Unit (DU), a Radio Unit (RU) and a method performed therein with respect to wireless communication. Furthermore, a computer program and a computer readable storage medium are provided herein. In particular, embodiments herein relate to processing communications, such as processing data in a wireless communication network. Background In a typical wireless communication network, user Equipment (UE) (also referred to as a wireless communication device, a mobile station, a Station (STA), and/or a wireless device) communicates with one or more Core Networks (CNs) via a Radio Access Network (RAN). The RAN covers a geographical area which may be divided into service areas or cells, with each service area or cell being served by a radio network node, e.g. an access node, such as a Wi-Fi access point or a Radio Base Station (RBS), which in some networks may also be referred to as e.g. a NodeB, a gndeb or an eNodeB. A service area or cell may be understood as a geographical area where wireless services can be provided by a radio network node. The radio network node may operate on radio frequencies to communicate over an air interface with UEs within range of the radio network node. The radio network node may communicate with the UE via a Downlink (DL) and the UE may communicate with the radio network node via an Uplink (UL). Universal Mobile Telecommunications System (UMTS) may be understood as a third generation (3G) telecommunications network evolved from the second generation (2G) global system for mobile communications (GSM). UMTS Terrestrial Radio Access Network (UTRAN) may be understood to be essentially a RAN that uses Wideband Code Division Multiple Access (WCDMA) and/or High Speed Packet Access (HSPA) for communication with user equipment. In a forum called the third generation partnership project (3 GPP), telecommunication providers have proposed and agreed upon standards for current and next generation networks and have investigated, for example, enhanced data rates and radio capacity. In some RANs, such as in UMTS, several radio network nodes may be connected (e.g., by landlines or microwaves) to a controller node, such as a Radio Network Controller (RNC) or a Base Station Controller (BSC), which may monitor and coordinate various activities of the plurality of radio network nodes connected thereto. The RNC may typically be connected to one or more core networks. Specifications of Evolved Packet System (EPS) have been completed within 3GPP and upcoming releases of 3GPP, such as New Radios (NR) and 6G, are being formulated. EPS may be understood to include evolved universal terrestrial radio access network (E-UTRAN) (also known as Long Term Evolution (LTE) radio access network) and Evolved Packet Core (EPC) (also known as System Architecture Evolution (SAE) core network). The E-UTRAN/LTE may be understood as a 3GPP radio access technology, wherein the radio network node may be directly connected to the EPC core network. Thus, the Radio Access Network (RAN) of an EPS may be understood as having a substantially "flat" (flat) architecture comprising radio network nodes directly connected to one or more core networks. The use of very many transmit and receive antenna elements may be of great interest in emerging 5G technologies such as New Radio (NR) as this may allow beamforming, e.g. transmit side beamforming and receive side beamforming, to be utilized. Transmit side beamforming may be understood to mean that a transmitter may amplify a transmit signal in one or more selected directions while suppressing transmit signals in other directions. Similarly, on the receiving side, the receiver may amplify signals from one or more selected directions while suppressing unwanted signals from other directions. An open RAN (O-RAN) may be made possible by a set of standards to be used by the provider. Thus, one or more open RAN (ora) nodes may be included in the wireless communication network. A ORAN node may be understood as a node in a wireless communications network capable of supporting the ORAN specification (e.g., a specification published by the O-RAN alliance or any similar organization) and may operate independently or in conjunction with other nodes to implement one or more functions of any node in the wireless communications network, including one or more network nodes and/or core network nodes. Examples of ORAN network nodes may include open radio units (O-RUs), open distributed units (O-DUs), open central units (O-CUs), RAN intelligent controllers (near real-time or non real-time) including O-CU control planes (O-CU-CPs) or O-CU user planes (O-CU-UPs), managed software or software plug-ins (e.g., near real-time control applications (e.g., xApp) or non real-time control applications (e.g., rApp)), or any combination thereof (adjectives "open" means support ORAN specifications).
