- a second parameter X c different from the ID of the cell B and then selecting a predefined value as the first parameter “ sc , such that UE1 and UE2 implement orthogonal matching by configuring the same second parameter X c and the first parameter “ sc ” .
- the base station A selected cell ID for the UE1 UE1 as a second parameter [chi] [alpha], [alpha] and select a slot number as the first cell A parameter n sA , selects the ID of the cell A as the second parameter X A of the UE3 for the UE3, and then selects the slot number of the cell A as the first parameter “ sA ”, thereby implementing orthogonal matching of the UE1 and the UE3. Therefore, the method for generating a pilot sequence in the embodiment of the present invention can support users in a non-synchronized cell to implement orthogonal pairing, and can also support orthogonal matching between users in non-synchronized cells.

- FIG. 10 shows a schematic flow diagram of a method 300 of generating a pilot sequence in accordance with yet another embodiment of the present invention. As shown in FIG. 10, the method 300 includes:
- the selection of the second parameter of the currently generated pilot sequence relies on the scrambling code identifier " seiD ".
- seiD the scrambling code identifier
- the communication device that performs the method 300 may be a base station or a device.
- the user equipment determines a second parameter used to generate the pilot sequence according to the currently scheduled rank, and dynamically selects the second parameter in a high-rank scheduling moment.
- S310 includes:
- the second parameter is determined according to a schedule in which the latest rank is less than the preset value before the current moment.
- the user equipment determines the second parameter according to the latest scheduling information whose rank is less than the preset value.
- the user equipment determines the second parameter according to the scrambling code ID in the scheduling information whose rank is less than the preset value. Because of the low rank, the scrambling code ID can have two values, thus increasing the degree of freedom of selection.
- the user equipment determines that the second parameter is a second parameter that is used by a scheduling whose last rank is less than a preset value. That is to say, the second parameter used when the latest rank is less than the preset value is directly used. Since the second parameter used in the low rank may also have two choices, the degree of freedom of the second parameter selection can also be improved.
- the preset value is 3, and at the time of TO, the rank of the scheduling is 1, and " saD is configured as 1, and the selected second parameter is X (1); at time T1, the rank of the scheduling is 5, greater than the preset value, the second parameter X ( 1 ) selected by the TO time is used. If the SOD is set to 0 at the time of TO and the second parameter selected is ⁇ (0), then at the time T1, the second parameter X(0) selected at the time of TO is used, so that the value of the second parameter at time T1 is obtained. It is no longer possible to only have one value, which improves the freedom of choice of the second parameter, which is conducive to interference coordination.
- S310 includes:
- the user equipment determines the second parameter according to the slot number of the downlink synchronization.
- the user equipment determines the second parameter according to the slot number of the downlink synchronization, and the corresponding relationship between the slot number and the second parameter.
- the base station and the user equipment may pre-establish a correspondence between the slot number and the parameter in the second parameter candidate set. For example, slot numbers 1, 3, 5, 7 correspond to X ( 0 ) in the second parameter candidate set; slot numbers 2, 4, 6, 8 correspond to X ( 1 ) in the second parameter candidate set.
- the user equipment uses the second parameter corresponding to the slot number of the downlink synchronization, which also increases the degree of freedom of the second parameter selection.
- the user equipment In S320, the user equipment generates the pilot sequence according to the second parameter. Specifically, the user equipment first determines an initial value of the pilot sequence from the second parameter, and then determines the pilot sequence from the initial value. For example, c imt can be generated according to equation (1), and then a pilot sequence can be generated by c imt .
- the method for generating a pilot sequence in the embodiment of the present invention determines the second parameter used to generate the pilot sequence according to the rank of the current scheduling, and improves the degree of freedom of selection of the second parameter, which is advantageous for interference coordination.
