The goal of this technical report is to describe the agreed approach towards
24、the RF related issues raised in 1: A) The existing 1.28Mcps BS classes did not fully address the RF requirements of the Home NodeB application. Proposals for changes to radio performance requirement specifications TS 25.105 are therefore provided in this report, together with the proposals for the t
25、est specification TS 25.142. B) The report intends to provide guidance to mitigate interference and clarify some interference cases 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either sp

30、 for 1.28Mcps TDD Home NodeBs is observed to provide attractive services and data rates in home environments in China as a consequence of a large number of TD-SCDMA subscribers within recent years. Whereas UTRAN is not optimally suited for this application, as it was developed and defined under the
31、assumption of coordinated network deployment. Actually home NodeBs are typically associated with uncoordinated and large scale deployment. Aim of this work item is to amend the 1.28Mcps TDD Home NodeB related RF specifications as suggested in the RAN4 specific part of TR 25.866 to support the Home N
32、odeBs application. No changes to the UE RF specifications are foreseen. 4.1 Task description TR 25.866 suggests that the existing 1.28Mcps TDD Base Station classes do not fully address the RF requirements of the Home NodeB application. TR 25.866 summarises the areas where changes to TS 25.105 are ex
33、pected to transmitter characteristics, receiver characteristics and performance respectively. And guidance to mitigate interference and interference test are needed to be investigated. Correspondingly, there are 2 objects in this WI, - To update the RF requirement specification TS 25.105 as suggeste
34、d by TR 25.866. - Guidance to mitigate interference and interference test are need clarification. 5 Radio scenarios 5.1 Deployment configurations 5.2 Interference scenarios 6 HNB class definition 6.1 Changes in 3GPP TS 25.105 This section describes the changes to BS RF requirements specifications TS
35、 25.105 6.1.1 Changes on transmitter characteristics 6.1.1.1 Maximum Home NodeB output power Maximum output power, Pmax, of the base station is the mean power level per carrier of the base station measured at the antenna connector in a specified reference condition. The period of measurement shall b
36、e a transmit timeslot excluding the guard period. Considering interference of Home NodeB, it is suggested that Home NodeB output power should be controlled. According to TR25.866, Considering two common Home NodeB scenarios(Home and small-scale corporation), the following two Max. output power level
37、 are recommended in Table 6.1.1.1-1. Table 6.1.1.1-1: Recommended power of Home NodeB Power class Max. output Power Scenario ETSI ETSI TR 125 968 V13.0.0 (2016-01)73GPP TR 25.968 version 13.0.0 Release 131 20 mW (13dBm) Home 2 100 mW(20dBm) Small-scale Corporation Correspondingly, the rated output p
38、ower, PRAT, of the Home NodeB is suggested to be specified in the TS 25.105. In summary, two types of Home NodeB should be defined in specifications, that is, - type 1: the output power of the Home NodeB is limited to 20 dBm - type 2: the output power of the Home NodeB is limited to 13 dBm A minimum
39、 requirements was also introduced: In normal conditions, the Base station maximum output power shall remain within +2 dB and -2dB of the manufacturers rated output power. In extreme conditions, the Base station maximum output power shall remain within +2.5 dB and -2.5dB of the manufacturers rated ou
40、tput power. In certain regions, the minimum requirement for normal conditions may apply also for some conditions outside the range of conditions defined as normal. 6.1.1.2 Frequency Accuracy Considering Home NodeBs are usually deployed at home and office, it is most likely that the serving UEs are i
41、n slow mobility profile and a consensus was reached that the Home NodeB is expected to support UE speeds up to 30km/h speed during the 1.28Mcps TDD Home NodeB SI. According to 25.866 simulation results, the Home NodeB modulated carrier frequency can be relaxed to 0.25 PPM. 6.1.1.3 summary of transmi
42、tter change The changes on transmitter characteristics in TS 25.105 are summarised in the following table. Table 6.1.1.3-1: Changes on transmitter characteristics to TS 25.105 Section Requirement Discussion / Required Changes 4.2 Base station classes Add a new BS class Home NodeB. Home NodeBs are ch
43、aracterized by requirements derived from Femto Cell scenarios. 6.2.1 Base station maximum output power Two types of Home NodeB should be defined in specifications, that is, type 1: the output power of the HNB is limited to 20 dBm type 2: the output power of the HNB is limited to 13 dBm 6.3 Frequency
44、 error Added frequency error requirement for Home BS It was agreed on a minimum frequency error of 0.25ppm 6.1.2 Changes on receiver characteristics 6.1.2.1 Sensitivity According to 3GPP TR25.866, using the reference measurement channel specified in 25.105 Annex A, the reference sensitivity level an
45、d performance of the BS shall be as specified in Table 6.1.2.1-1. Table 6.1.2.1-1: 1.28Mcps TDD Home NodeB reference sensitivity level BS Class Reference measurement channel data rate BS reference sensitivity level BER 1.28Mcps TDD Home NodeB 12.2 kbps -101 dBm BER shall not exceed 0.001 ETSI ETSI T
46、R 125 968 V13.0.0 (2016-01)83GPP TR 25.968 version 13.0.0 Release 136.1.2.2 Dynamic range Receiver dynamic range is the receiver ability to handle a rise of interference in the reception frequency channel. The receiver shall fulfil a specified BER requirement for a specified sensitivity degradation
47、of the wanted signal in the presence of an interfering AWGN signal in the same reception frequency channel. Considering impact of co-channel uplink interference on the Home NodeB, it is possible that Home NodeB receiver will be exposed to strong interference signals from un-coordinated UEs. It was s
48、hown that the FDD Home NodeB dynamic range requirement needs to be extended by 20dB to protect the HNB from the strong interference signal of an un-coordinated UE. This conclusion can be reused in 1.28Mcps TDD Home NodeB. The BER shall not exceed 0.001 for the parameters specified in Table 6.1.2.2-1
