Definitions
- the invention relates to a method and a measuring system for measuring the power and quality of a mobile radio terminal (UE).
- UE mobile radio terminal
- HSDPA High Speed Downlink Packet Access
- UMTS LTE Long Term Evolution
- HSDPA and UMTS LTE use new technologies that allow data rates of up to 14 Mbit / s and which further increase the capacity of the
- Mobile communication network as such. As a result, mobile operators can offer their customers enhanced multimedia services.
- FIG. 1 there is shown a schematic representation of the HDSPA technology, particularly the logical (and physical) channels used in HDSPA.
- Significant is the introduction of a new transmission channel for user data, the so-called High-Speed (Physical) Downlink Shared Channel, HS- (P) DSCH.
- HS- (P) DSCH Different users share the Air Interface resources available on this channel.
- An intelligent algorithm in the Node B decides which participant receives a data packet at which time. This decision is communicated to the participants via a parallel signal channel, the so-called High-Speed Shared Control Channel, HS-SCCH.
- HSDPA can transmit packets every 2 ms.
- the HS-DPCCH is a physical uplink channel used to convey control information: HARQ ACK / NACK and channel quality information.
- Fig. 2 shows a schematic representation of the structure of the HS-DPCCH.
- the channel quality information consists of the so-called CQI value, which refers to the CQI tables described in the 3GPP specification TS 25.214 ("Physical layer procedures")
- CQI value refers to the CQI tables described in the 3GPP specification TS 25.214 ("Physical layer procedures")
- UE terminals
- Table 1 shows the CQI table for the UE categories 1 to 6.
- the CQI values regularly reported by the terminal (UE) are considered by Node B as a suggestion of how to format the HS (P) DSCH.
- the terminal (UE) requires the resulting block error rate of the HS-DSCH to be less than 0.1.
- the higher the CQI value the more demanding is the transmission format of the HS-DSCH, ie the better the quality of the radio connection must be.
- the terminal (UE) reports a CQI value of 14 according to Table 1, it proposes a HS (P) DSCH format with burst block size 2583 bits, 4 channels and QPSK (Quadrature Phase Shift Keying) modulation ,
- QPSK Quadrature Phase Shift Keying
- Transmission block error rate of the HS-DSCH is estimated to be below 0.1. Should Node B ignore the terminal (UE) suggestion and select a transmission format with higher requirements according to a higher CQI value, a higher one would very likely
- the Node B should ideally one
- AMC Adaptive Modulation and Coding Method
- HSDPA also uses a so-called HARQ (Hybrid Automatic Repeat Request) protocol.
- HARQ Hybrid Automatic Repeat Request
- Node B may choose a different type of encoding which allows the subscriber better reception (incremental redundancy). This type of coding is referred to in the jargon as “redundancy and constellation version”, or in short, as
- RV version Redundancy version
- NACK negative acknowledgment
- the Node B can transmit other data packets to this terminal (UE) via other HARQ processes.
- a terminal device must support up to 8 parallel HARQ processes that are equivalent to up to 8 independent HARQ stop-and-wait transmission mechanisms.
