Quick-retransmission method and method in wireless chain control layer determination mode

The invention discloses a quick-retransmission method in a wireless chain control layer determination mode. The method comprises the steps that: a sending end resolves negative acknowledgement (NACK) information in a state report; and the sending end judges conditions according to the final group of NACK information, determines data required to be retransmitted, assembles the data required to be retransmitted into a retransmission queue and then sends the data to a receiving end. The invention also discloses a quick-retransmission device in a wireless chain control layer determination mode, which comprises a state report receiving end, a state report resolution unit, a state report judging and determining unit and a data retransmission unit, wherein the state report receiving unit is usedfor continuously receiving state reports from an opposite end; the state report resolution unit is used for resolving the NACK information in the state report; the state report judging and determining unit is used for judging conditions according to the final group of NACK information and determining the data required to be retransmitted; and the data retransmission unit is used for sending the retransmission data assembled in the retransmission queue to the receiving end. When the method and the device of the invention are used, resource waste and time delay can be avoided.

Wireless relay network uplink transmission method based on blind known interference cancellation

The invention discloses a wireless relay network uplink transmission method based on blind known interference cancellation. The wireless relay network uplink transmission method based on the blind known interference cancellation is characterized in that two users are simultaneously transmitted at a first time slot when the channel capacity between a first user and a base station is lower than transmission rate requirements and business data of a second user can be coded by the base station under the interference of sent signals of the first user, wherein the first user is located in a relay node business coverage area and the second user is located in a high-speed business coverage area, and the base station codes the second user business data and recovers second user dispatching signs from the composite signals of the two user; relay nodes can receive composite signals from the two users in a first time slot and the relay nodes amplify and transmit the composite signals in a second time slot; and the base station receives the composite signals which are transmitted by a relay in the second time slot and carries out the business data of the first user which are recovered by the blind known interference cancellation (BKIC). The wireless relay network uplink transmission method based on the blind known interference cancellation can accomplish uplink transmission of the two users in wireless relay network by only using two time slots in probability of tending to one under the condition of a higher signal to noise ratio. System spectrum efficiency is improved.

Method, device and system for automatically verifying authenticity and repetition of invoice

The invention provides a method, device and system for automatically verifying authenticity and repetition of an invoice. The method comprises: storing values of a plurality of invoice information items of each invoice reported to a tax bureau for invoice reimbursement; identifying an invoice uploaded from the outside to obtain the invoice code and the value of the invoice number; when the invoiceneeds to be verified, sending the two values to a tax bureau to send an invoice verification request, and receiving a corresponding verification passing notification sent by the tax bureau when the tax bureau passes the verification, otherwise, executing verification failure processing according to a corresponding verification non-passing notification sent by the tax bureau to enable the invoicenot to be reported to the tax bureau for invoice reimbursement; when the invoice needs to be subjected to repetition checking, inquiring whether values of a plurality of invoice information items of the invoice are stored or not according to the two values, the invoice code and the invoice number of the invoice information items being the same as the two values respectively, and if so, executing repetition checking failure processing so that the invoice information items cannot be reported to a tax bureau to be used for invoice reimbursement. According to the scheme, the problem invoice can beprevented from being reported to a tax bureau by verifying the authenticity and repetition of the invoice is solved.
