Description of the invention: [Technical field to which the invention belongs] This Qi Mingcai is about the multi-round (10) M(1) technology of Xiang Duo. In particular, the present invention is directed to an optimum setting for multiple antenna arrays that select multiple input multiple output capabilities. [Prior Art] ^ The wireless track device with a multi-antenna antenna provides a variety of transponder and reception benefits over a device having only a single antenna. The basis of diversity is that the antenna with the best reception is chosen for reception or transmission at any given time. While devices utilizing antenna diversity may have multiple physical antennas, signal processing has only a single set of electronic circuits' which are also referred to as radio frequency (RF) chains. Multiple Input Multiple Output Wireless Technology improves the diversity of antennas that utilize multiple RF chains. Each RF chain can be received and transmitted simultaneously. In this way, multiple input multiple output devices can achieve higher processing power and eliminate the negative effects of multipath interference. In the transmission device, each radio frequency chain is responsible for transmitting a spatial stream. A single frame can be decomposed and multiplexed into multiple spatial streams, which are subsequently reassembled into the receiver. Multiple Input Multiple Output is one of the most promising technologies in wireless communications. Unlike traditional smart antenna technologies that mitigate unfavorable multipath fading and enhance single data stream strength, multiple input multiple output systems utilize multiple path fading to simultaneously transmit and receive multiple data streams. In theory, the ability to multiple input multiple output systems increases linearly with the number of transmit and receive antennas. Multiple Input Multiple Output is considered by various wireless data communication standards 201015895, such as IEEE lln and 3Gpp Broadband Split (WCDMA). When multiple input multiple output is implemented, the WTRU can operate. (4) Multi-work mode or spatial diversity mode. In spatial multiplex mode, the WTRU transmits multiple independent streams of data to maximize data processing capabilities. In contrast, in the spatial diversity mode, the WTRU can transmit a single-data core via multiple =, two 。. Based on the mode, the WTRU can select the appropriate combination of quality metrics or quality metrics for the choice of beam combination. In general, the mXN channel matrix η system may have the following form: 、 , where the label under the component h indicates the antenna a, ..., the melon and the receiving WTRU that are assigned to the transmitting WTRU. The contribution of the various antenna mappings of the antenna a'...' Hi. The WTRU can obtain the correction matrix K in a similar manner. The correction of the wireless local area network (LAN) context includes calculating a set of complex correction coefficients that are multiplexed on the basis of the antenna (per-turn) and per-sub-carrier basis. When transmitting the baseband stream of the WTRU, the difference in response of the transmission and reception processing paths (until the unknown constant across the antenna) can be equalized. Please refer to FIG. 1 , which shows a channel correction signal of the prior art 201015895 (10). The transmitting wireless transmission/reception unit (TxWTRU) (10) is mainly receiving the wireless transmitting/receiving unit (the two channels between the knowing (10). transmitting the wireless transmission/receiving single illusion 1 传输 transmission correction training king CTF) 131 to receiving wireless Transmission/reception unit 120.

Smart antennas, especially beamforming, are used in conjunction with signal processing techniques that control the directionality of the radiation pattern, or the sensitivity of the transmitter or receiver array. When receiving a signal, beamforming increases the gain of the desired signal direction and reduces the gain in interference and noise directions. When transmitting a signal, the beamforming system can increase the gain of the direction in which the burst is to be transmitted. The combination of multiple antennas and multiple antennas (4), the number of available antenna maps is dramatically increased. When the beamforming antenna is included in the WTRU, the number of available antenna maps can be extremely large. In order to optimize the communication connection between the two wireless transmission/receptions, the appropriate antenna mapping for the _select transmitter and receiver has its needs. In view of the above, the present invention provides a method and apparatus for beam-to-field recording of multiple available antenna mappings for capable wireless devices. SUMMARY OF THE INVENTION The present invention is a method and an I-station for selecting an antenna mapping of multiple input multiplexes. At present, it is possible to use the antenna mapping unit to select the 'target mapping' to receive the transmission/receive.

If the switching antenna is used, the 'single-active antenna component can be used with a single amount of passive passive antenna 10 201015895. The antenna beam pattern can be adjusted by adjusting the impedance of the passive antenna component. The impedance adjustment can be implemented by controlling a group of switches connected to the antenna elements. Alternatively, the antenna may be a composite with multiple antennas, which may all be omnidirectional antennas. For example, three omnidirectionals with selected physical spacing The antenna system can be turned on or off according to the control signal from the selected state 324 to define different beam combinations. For convenience, please refer to Figure 3. Transmission wireless transmission/receiving unit 310 (also referred to as Tx WTRU in the following description) includes two radio frequency chains 312 and 312. The beam selector 314 is coupled. A plurality of omnidirectional antennas 316 Α 316 316 到 to RF chains 312 Α and 312 。. In view of this, the number of possible antenna mappings of the transmission WTRU 108 is twice the number of radio frequency chains. The receiving WTRU 32 〇 (In the following description, also referred to as Rx WTRU) also includes two RF chains 322 and 322. Beam selector 324 is coupled to a plurality of anisotropic antennas 326α-326μ to RF chains 322 and 322. As previously described, In a simple example embodiment, each beamforming antenna 326 eight to 326 can be secreted into three directional beams. In this case, the receiving WTRU 32 has a total antenna map multiplied by the number of beams multiplied by the number of radio frequency bonds. The combination of all possible antenna mappings that can be used for any transmission X is called "superset," and the size of the supers is expressed as Nsuperset. Nsuperset can be very large and, at any given It may also be impractical to utilize all available antenna mappings for a given time. ... Candidate combinations are sub-combinations of supersets, and 'candidate combinations can be used for selected antenna mapping sets at any given time. Better 201015895' candidate combination The size is limited between 8 and 22 sets of antenna maps. The candidate combinations are not static, whereas the candidate combinations are dynamic, and the candidate combinations can change over time to reflect the changed channel conditions. The transmission workstation can continuously or periodically monitor the channel conditions of all antenna mappings in the current candidate combination, and if the measured channel conditions fail to meet the predetermined threshold for a predetermined time, the transmission operation can modulate the candidate combination. This can be done by discarding several sets of antenna mappings in the current candidate combination and adding several new days. Mapping, and/or retaining sets of antenna mappings in the candidate set ^ can be reduced. In high speed applications, the candidate combinations can be reduced, or the antenna mapping can be stopped simultaneously. ❹ In a preferred embodiment of the invention, The WTRU can select any antenna mapping via the candidate combination. The choice of antenna mapping is based on the long-term scale. The tracking of the packet-by-packet channel does not need to be implemented. Therefore, the choice of antenna mapping does not follow the path. Rapid change (or micro-structure). It should be noted that the candidate combination is changed by t (4) occurs in any of the (four) packets of the transmission or reception of the single! w ' during the operation, receiving wireless Transmission, wiring is measured by the correction unit 318.

Preferably, the calibration unit is compatible with the implementation. IEEE standard signal transmission and message delivery, such as: IEEE 802.il family standard, and in particular, IEEE 8 〇 2 lm standard. ❹ ❹ Various quality metrics can be used to determine the desired antenna mapping. Entity (PHY) layer, The Media Access Control (MAC) layer, or higher-level metrics are appropriate. Preferably, the quality metrics include, but are not limited to, channel prediction, signal noise and dry _ (SNIR), and Wei news surface roughness (RSSI). Short-term data miscellaneous, packet error (pER), dragon rate, wireless transmission/reception single-it operation mode 4, the size of the maximum eigen-vaiue of the receiving channel, or the like.
