ETSI ETSI GS ORI 002-1 V4.1.1 (2014-10)61 Scope The present document defines low layer protocols aspects of the Open Radio equipment Interface (ORI). Low layer protocols are those terminating the ORI Link (a bi-directiona

16、l interface in-between two directly-connected ORI ports, on two ORI nodes). The Layer 1/2 protocols of CPRI Specification 1 have been used as a baseline for which further requirements for protocols up to and including the Layer 2 have been defined. See the associated specification “Requirements for

17、Open Radio equipment Interface“ 2 for more information on how the Low Layer protocols relate to other aspects of the ORI interface. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

34、0 shall not be used but is reserved for possible future purposes (e.g. testing); therefore up to 255 ports per node can be addressed. Reserved byte: The transmitter shall send zero for the reserved byte and the receiver shall not interpret this byte. The size of the PORT_ID is 8 bytes in total such

35、that the information completely fills two bytes (Y = 0, Y = 1) of the subchannel. For line rates higher than 1,228 Gbps, the additional bytes (Y 1) of the subchannel shall be treated as reserved.

38、ion based on the PORT_ID is given in Annex A. 6.3.2 UTRA RTWP measurement report For UTRA-FDD operation, the Received Total Wideband Power (RTWP) shall be measured and reported from the RE on the ORI link as defined below: 1) RTWP measurement definition: The received total wide band power, including

39、 noise generated in the receiver, within the bandwidth defined by the receiver pulse shaping filter. The reference point for the measurement shall be the RE (Rx) antenna port, including in the case that receiver diversity is in use by the RE. It is the responsibility of the REC to use the correspond

40、ing RTWP reported values to derive the RTWP measurement defined by TS 125 215 6. 2) RTWP measurement period in the RE: The RTWP measurement period shall be 2 ms. 3) RTWP measurement accuracy minimum performance requirement: The RTWP measurement performed by RE shall have an accuracy such that the re

41、ported value received by the REC allows the REC to meet the RTWP minimum performance requirements defined in TS 125 133 7 corresponding to the Base Station class supported by the RE. 4) RTWP measurement reporting by the RE performing the RTWP measurement: - Reporting conditions: square4 The Received

42、 Total Wideband Power measurement shall be reported per AxC of type “UTRA-FDD“. Reporting is required for all AxCs of type “UTRA-FDD“ that are configured and reporting shall be performed autonomously by the RE. For each AxC, a RTWP reported value shall be reported from the RE in the RTWP measurement

43、 report control word on the ORI link (the mapping to the ORI link is defined in GS ORI 002-2 9) in every hyperframe, and shall be updated for each AxC by the RE every 2 ms, in hyperframe number 0, 30, 60, 90, 120 (HFN#0, 30, 60, 90, 120). NOTE: An AxC is configured by higher layers as defined in GS

44、ORI 002-2 9. ETSI ETSI GS ORI 002-1 V4.1.1 (2014-10)13square4 Mapping of RTWP measured values to RTWP reported values: - The RTWP measured value is adjusted according to the value of “Uplink feeder adjustment“ prior to reporting, as defined and indicated to the RE in GS ORI 002-2 9. - In Table 6.3.2

45、.1 the mapping of the RTWP measured value (after feeder adjustment) to the RTWP reported value is defined. The reporting range for RTWP is from -112 dBm to -50 dBm. - The range in the signalling may be larger than the guaranteed accuracy range. The reported value shall be expressed in 0,1 dB steps.

47、eport to the RTWP measurement report control word: For the mapping of the RTWP reported value to the RTWP measurement report control word, a unique AxC RTWP group shall be defined in the RE performing the RTWP measurement, for each AxC for which RTWP reporting is required. The mapping of AxC to AxC

48、RTWP group is defined in GS ORI 002-2 9. Based on the frame structure described in 1, the mapping of each AxC RTWP group n within the location, defined by Y and Xs, of the RTWP measurement report control word within subchannels 50 and 51 shall be derived using the following formula: AxC RTWP group n

49、 = (Y*4) + Xs Table 6.3.2.2 provides an example of the mapping of each AxC RTWP group for Y = 0(T/8)-1, where the parameter T is defined in the CPRI specification 1.
