6.1 General

25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)

Unless otherwise stated, the transmitter characteristics are specified at the antenna connector of the UE. For UE with integral antenna only, a reference antenna with a gain of 0 dBi is assumed. Transmitter characteristics for UE(s) with multiple antennas/antenna connectors are FFS.

The UE antenna performance has a significant impact on system performance, and minimum requirements on the antenna efficiency are therefore intended to be included in future versions of the present document. It is recognised that different requirements and test methods are likely to be required for the different types of UE.

UEs supporting DC-HSUPA shall support both minimum requirements, as well as additional requirements for DC-HSUPA.

Unless otherwise stated, for the additional requirements for DC-HSUPA, all the parameters in clause 6 are defined using the UL E-DCH reference measurement channel, specified in subclause A.2.6. For the additional requirements for DC-HSUPA, the spacing of the carrier frequencies of the two cells shall be 5 MHz.

Unless otherwise stated, for the additional requirements for DB-DC-HSUPA, all the parameters in clause 6 are defined using the UL E-DCH reference measurement channel, specified in subclause A.2.6.

UEs supporting Open-Loop uplink Transmitter Diversity shall support both minimum requirements for one of transmit antenna connectors, which one to be tested shall be declared by the manufacturer, and additional requirements for UL OLTD. In addition, the additional requirements for UL OLTD are applicable only in the case when equal power is transmitted from two active antenna ports.

DC-HSUPA and UL OLTD do not operate simultaneously in the UE.

DB-DC-HSUPA and UL OLTD do not operate simultaneously in the UE.

UEs supporting UL CLTD shall support both minimum requirements, as well as additional requirements for UL CLTD.

The requirements in clause 6 for UEs supporting UL CLTD are specified for UL CLTD activation states 1, 2, 3 which are defined in sub-clause 4.6C.2.2.3 in TS 25.212[10].

DC-HSUPA and UL CLTD do not operate simultaneously in the UE.

DB-DC-HSUPA and UL CLTD do not operate simultaneously in the UE.

UEs supporting UL MIMO shall support both minimum requirements, as well as additional requirements for UL MIMO.

The requirements in clause 6 specified for UL MIMO are applicable for UL MIMO rank-2 transmission. The requirements for UL MIMO rank-1 transmission are covered by UL CLTD requirements. UL MIMO rank-1 and rank-2 transmissions are defined in clause 11 of TS25.214 [8].

DC-HSUPA and UL MIMO do not operate simultaneously in the UE.

DB-DC-HSUPA and UL MIMO do not operate simultaneously in the UE.
