Field of application
The present invention relates to the field of mobile communications and, in particular, to method and system for configuration alarm physical channel sharing rising connection.
The level of equipment
In the system 3GPP LTE 3rd Generation Partnership Project (Long Term Evolution) data link control for user equipment (UE) for the physical channel sharing rising connection (PUSCH) by Central planning data to the base station.
Information related to planning of the rising channel PUSCH, is sent to the target hardware user base station for physical control channel downlink (PDCCH). Information about planning of the rising connection contains information management, such as the allocation of resources in relation to the channel, the decision of modulation and encoding and cyclic shift to the reference signal demodulation (hereinafter abbreviated DMRS).
Channel PDCCH is used as a carrier of information related to the planning of the rising connection, as well as information on capacity management and downlink. Information management downlink (DCI) can have a number of formats:
DCI-0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A and so on.
The format DCI-0 is used for the transmission of information related to the planning data on the physical channel sharing rising connection (or shortly PUSCH);
formats DCI-1, 1A, IB, 1C and ID is used for a variety of transmission modes on the physical channel of the joint use downlink (hereinafter abbreviated PDSCH) with a single transport unit (TV);
formats DCI-2 and 2A is used for a variety of transmission modes for multiplexing with spatial separation; and
formats DCI-3 and 3A will be used to give instructions related to the management capacity for physical control channel the rising connection (PUCCH) and channel PUSCH.
The LTE system-A (LTE-Advanced) is the next generation LTE-system. In technologies of relevance to the LTE system, format DCI-0 planning rising connection does not support mnogoetajnoe transfer of the rising connection, and so on systems LTE-A mnogoetajnoe transfer of the rising connections to strengthen the display function of the signal, it is necessary to add a new format called DCI-X in DCI planning rising connection, or extend the length of the alarm system on the basis of the existing alarm type format DCI-0.
In the system LTE format DCI-0 contains the following information:
- a flag to distinguish between formats DCI-0 and DCI-1 A;
flag spasmodic change the frequency;
- attributing resource unit and attributing resource frequency-hopping;
- modulation scheme and coding (MCS) and the version of redundancy (RV);
- indicator new data (NDI);
- team management transmit power (TRS) for channel PUSCH, you schedule of data transmission;
- cyclic shift to the reference signal demodulation (DMRS);
- index rising connection (UL), which is applied only in duplex system time division (TDD) and used when configuration «0» upward/downward connection;
index - prescription descending the connection that exists only in the system of TDD and used configurations «1»-«6» upward/downward connection;
request status display channel (CQI).
Cyclic shift to the reference signal demodulation channel PUSCH, you schedule data, specified, as shown in Table 1.
Table 1Field cyclic shift

format DCI-0
000 0 001 6 010 3 011 4 100 2 101 8 110 10 111 9In the LTE system-A canal PUSCH can be used transmission via port or through port. Figure 1 shows schematically the process signal processing base frequency bands on a transmitting party on the physical channel sharing rising connection in the existing system LTE-A using transmission through port.
As shown in figure 1, when the transfer is performed through port system LTE-A supports spatial multiplexing based on one or two of code words (CW), each of which corresponds to one transport unit (TV), or the ratio of conformity between the transport unit and the code word can be changed using the flag permutations between transport unit and code word. Thus, the system LTE-A supports the transfer mode with one transport unit or two transport units.
The code word is also displayed in the layers, namely each code word is written in the form of data on one or two layers. Figure 2 schematically shows how to write a display of a code word for the layer. This operation is performed using the rendering engine, and its function for simplicity, let us consider the example of two words and four transmit antennas. If two code words are displayed on two layers, codeword 0 is directly displayed on the first layer, and codeword 1 directly displayed on the second layer. If two code words are displayed into three layers, the code word 0 is directly displayed on the first layer, and the code word is shown on the second layer and the third layer after serial-to-parallel conversion. If two code words are displayed on four layers, the code word zero is shown on the first layer and the second layer after serial-to-parallel conversion, and the code word is displayed on the third layer and the fourth layer after serial-to-parallel conversion.
Prior to encoding the data of each layer can be processed independently or in parallel, or the set of spatial-multiplexed layers can be moved by one symbol modulation (one character DFT-S-OFDM, or one slot) using the technology shift layers (LS). Figure 3 illustrates the result of this operation, in particular shows the location of the layers before and after shear layers. As shown in figure 3, on the transmission side optionally available shear modulus layers, but if you are encountering certain conditions, the module is disabled, the shift of layers will not be made.
If you are using spatial multiplexing on the basis of two codewords, and the shear layers is not enabled then the two words are made independent speed control, channel coding and modulation, and these two words receives an independent process hybrid request retransmission (HARQ). If you are using spatial multiplexing on the basis of two codewords, and the shear layers included, is a spatial data merge two layers, the two code words have the same modulation scheme and coding, and they are given one process hybrid request retransmission.
In the LTE system-A technology used linear pre-based encoding code tables. The technology of preliminary coding provides for preliminary processing of the signal at the sending end, using the information on the status of the channel (CSI), which enables to improve the work mnogoetajnoe system. One way of obtaining information about the status of the channel (CSI) on the transmission side is feedback from the host. To reduce transmission via the feedback channels of large volumes of General information is usually applied storage identical coding tables, namely sets of matrices preliminary coding, as the receiving party and a transmitting party. The receiving party chooses an appropriate matrix preliminary encoding from the encoding tables in accordance with the current situation in the channel and sends the index of the matrix preliminary coding (PMI), by which this matrix can be found in the set of matrices preliminary coding, back to the transmitting side. Obtained by the index of the matrix pre-coding the transferor finds an appropriate matrix and pre-coding of the transmitted signals. Mathematically model the preliminary data coding can be expressed as : y=HWs+n, where y is the vector of the received signal, N - matrix coefficient channel, W - matrix preliminary coding, s - vector signal, and n is the vector of noise.
The present invention is devoted to the solution of the following technical issues: how to ensure that the method and system for configuration alarm physical channel sharing rising compounds, namely, the problem of guidelines covering the orthogonal code (OSS) in information related to the planning of the rising connection on the physical channel sharing rising connection in the existing system of LTE.

In accordance with the technical solution proposed in the present invention, information management downlink (DCI) is defined and used in a way that she carries one or more types of information, and this ensures indication covering orthogonal code and/or rotated. Information management downlink used for planning of the physical link sharing of connection when passing through port when passing through port, or only used for planning of the physical link sharing rising connection with the transfer through port. Information management downlink is sent to the target hardware user base station for physical control channel downlink.
The proposed method configuration alarm physical channel sharing rising compounds contains the stage at which:
