42、 the 3.84Mcps TDD option to a higher chip rate. There exists a great degree of commonality between the 3.84Mcps TDD option and the 7.68Mcps TDD option. Nevertheless, there are many aspects of the 7.68Mcps TDD option that require separate specification to the 3.84Mcps TDD option. The following aspect
43、s are specified at a high level in this document: - Physical layer structure; - Physical layer procedures; - UE capabilities; - Layer 2/3 protocol aspects; - Iub / Iur aspects; - Radio aspects; ETSI ETSI TS 125 202 V15.0.0 (2018-07)83GPP TS 25.202 version 15.0.0 Release 155 Requirements - The 7.68Mc
44、ps TDD option shall provide significant enhancements in terms of user experience (throughput and delay) and/or capacity (at least to the extent shown in 1). - Full mobility shall be supported, i.e., mobility should be supported for high-speed UE cases also, but optimisation should be for low-speed t
45、o medium-speed scenarios. - It is highly desirable for the 7.68Mcps TDD option to maintain commonality with the 3.84Mcps TDD option. New features shall therefore provide significant incremental gain for an acceptable complexity. - The UE and network complexity shall be minimised for a given level of
46、 system performance. - The impact on current releases in terms of both protocol and hardware perspectives shall be taken into account. 6 Physical layer structure 6.0 Services offered to higher layers The 7.68Mcps TDD option supports an identical set of transport channels and indicators to the 3.84Mc
47、ps TDD option. 6.1 Frame structure The 7.68Mcps TDD option frame is of length 10ms and consists of 15 timeslots of duration 5120 * Tc, where Tcis the chip duration (Tc= 1 / 7.68 * 106= 130.2ns). Any timeslot in the frame can be either uplink or downlink. At least one timeslot in the frame is assigne
48、d to the uplink and at least one timeslot in the frame is assigned to the downlink. The frame structure is shown in Figure 6.1.1. time frequency 10ms 5120 * Tc7.68Mcps Figure 6.1.1: The 7.68Mcps TDD option frame structure 6.2 Burst structure The 7.68Mcps burst consists of two data field portions, a
49、midamble portion containing a training sequence and a guard period as shown in Figure 6.2.1. Several bursts can be transmitted at the same time where each burst uses a different OVSF channelisation code, but the same scrambling code.
