ITU-T G.9963 (2015)/Amd.1 (07/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (IC

13、Ts). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication

14、 Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of infor

15、mation technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agen

16、cy. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some

17、 other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or im

18、plementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development proc

Modifications introduced by this amendment are shown in revision

28、 marks relative to Recommendation ITU-T G.9963 (2015) plus its Corrigendum 1. 1 Scope This Recommendation describes the modifications to ITU-T G.9960 and ITU-T G.9961 that are needed to define MIMO home networking transceivers for operation over power-line or telephone wiring. More specifically, thi

29、s Recommendation includes the following: the PHY functional models of the MIMO transceivers; detailed descriptions of the modifications (changes and additions) needed in the PHY and DLL sections relative to ITU-T G.9960 and ITU-T G.9961; the means by which transceivers that comply with ITU-T G.9960,

30、 ITU-T G.9961 and this Recommendation ITU-T G.9963 interoperate when operating on the same wires; and the means by which transmissions from ITU-T G.9963 transceivers do not degrade the performance of transceivers that comply with ITU-T G.9960 and ITU-T G.9961 when operating on the same wires. An ITU

31、-T G.9963 transceiver shall be fully compliant with ITU-T G.9960 and ITU-T G.9961. NOTE In those regions, or particular installations, where only two conductors are used for mains sockets in the case of powerline or a single pair of wires is used in the case of telephone cable, a modem equipped with

32、 a MIMO transceiver will behave as an ITU-T G.9960 transceiver. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

ITU-T G.9963 (2015)/Amd.1 (07/2016) 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 ground conductor (G)

37、: A conductor in an electrical branch circuit that does not carry mains current under normal operation. It provides a low-impedance return path for ground-fault current back to the service entrance panel for the purposes of protecting personnel and equipment and ensuring circuit breaker trip. At the

38、 service entrance panel, this conductor is bonded to an earthing (grounding) electrode. In regulations in some regions this is commonly referred to as the equipment grounding conductor (EGC). NOTE 1 Some electrical appliances do not connect to the ground conductor. NOTE 2 The neutral and ground cond

39、uctors are commonly bonded together in the service entrance panel and nowhere else, by virtue of their common bonding to the earthing electrode. 3.2.2 MIMO channel: A channel that has multiple input ports (Tx ports) and multiple output ports (Rx ports). A “2 X 2“ MIMO channel has 2 Tx ports and 2 Rx

40、 ports. 3.2.3 MIMO transmission: Transmission where one or two spatial streams are converted into two transmit streams. 3.2.4 neutral conductor (N): A conductor in an electrical branch circuit that serves as the reference conductor and return path for current supplied by the circuits phase conductor

41、(s). At the service entrance panel, this conductor may be bonded to an earthing (ground) electrode. In such cases, regulations in some regions refer to it as the “grounded conductor“. NOTE Not all branch circuits include a neutral conductor. The term “grounded conductor“ should not be confused with

42、the term “ground conductor“ or EGC. 3.2.5 phase conductor (P): A conductor in an electrical branch circuit that is energized with mains voltage with respect to the circuits reference conductor. In regulations in some regions, this is commonly referred to as a “line conductor“. 3.2.6 spatial stream:

43、A stream of data that may be mapped for transmission over one or more ports. 3.2.7 transmit stream: A stream of symbols created by the Tx port mapper. Each transmit stream is assigned for transmission over a specific Tx port. 3.2.8 Tx (or Rx) port: In powerline, a physical connection to the power-li

44、ne medium using a combination of the available three conductors (phase (P), neutral (N), and ground (G) for transmitting and receiving signals. An example of a port is a pair of conductors, such as P-N, N-G or P-G. In a telephone cable, a physical connection to a pair of conductors. A port used for

45、transmission is called a “Tx port“. A port used for reception is called an “Rx port“. 3.2.9 Tx port mapper: A function that maps pairs of constellation points assigned to the two spatial streams on the same sub-carrier, to a modified pair of signals that (after orthogonal frequency division multiple

46、xing (OFDM) modulation, i.e., inverse discrete Fourier transform (IDFT) are connected to Tx ports. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: ACE Additional Channel Estimation APC Application Protocol Convergence BAT Bit Allocation Table BMAT Bit
