ETSI ETSI TR 136 922 V15.0.0 (2018-07)73GPP TR 36.922 version 15.0.0 Release 151 Scope The present document is the technical report for the work item on LTE TDD HeNB RF requirements, which was appr
37、oved at TSG RAN#43. The objective of the WI is to first identify the relevant scenarios and then write an RF requirements specification that is applicable to LTE TDD HeNB. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the pres

ETSI ETSI TR 136 922 V15.0.0 (2018-07)83GPP TR 36.922 version 15.0.0 Release 15HeNB Home Enhanced Node B HNB Home NodeB CSG Closed Subscriber Group GPS Global Positioning System4 General This work it
44、em has the following objectives: 1. Specify the RF requirements for the E-UTRA TDD Home eNodeB in TS36.104 and the corresponding updates on the test specification in TS36.141. Some requirements could refer to the outcome of existing/ongoing related studies. 2. Investigate and find out effective inte
45、rference control schemes to ensure good performance of both macro layer and HeNB. Although some of the studies could refer to UTRA HNB related work experience, e.g. deployment/interference scenarios, amount of studies are needed to find out the effective interference control schemes due to different
46、 physical techniques and system characters between E-UTRA and UTRA. The work should include but not be limited to the followings, The operator has the means to obtain interference control related measurements reports from HeNB and/or HUE, e.g. the strength of signals and the identity from the macro
47、cell layer and from other HeNBs. The operator has the means to set the maximum output power and/or frequency of HeNB. This is expected to introduce changes to TS36.104. The operator has the means to coordinate the HeNB and eNB timing and TDD configuration. This is expected to introduce changes to TS
48、36.104. The operator has guidance on how to control HeNB power and expected performance levels in the relevant scenarios. The scope of this work item is limited to the LTE TDD mode. 5 Radio scenarios 5.1 Deployment configurations In TR 25.967 7, a number of different deployment configurations have b
49、een considered for FDD Home NodeB, including: Open access or CSG (Closed Subscriber Group) Dedicated channel or co-channel Fixed or adaptive (DL) maximum transmit power For FDD or TDD Home eNodeB, the following deployment configuration should be considered in addition to the ones listed above: Fixed or adaptive resource partitioning Specifically, the resource partitioning could be performed in frequency, time or spatial dimensions for interference coordination. Frequency partitioning Most existing LTE ICIC mechanisms belon
