Abstract

A wireless communication apparatus that uses a communication protocol to transmit and receive data with a data check bit, including a received data determining section that performs a data check for received data by using the data check bit to determine whether the data is error; a received result transmitting section that, when determined to be error, discards the data and transmits a retransmission request to other wireless communication apparatus of the transmitting origin, whereas determined to be not error, transmits a message indicating that the data is normal to the other wireless communication apparatus of the transmitting origin; and a retransmission asking section that determines whether a format of the data is incorrect or normal, and when determined to be normal, passes the data to predetermined processing, whereas when determined to be incorrect, discards the data and asks the received result transmitting section to request retransmission of the data.

Claims

1. A wireless communication apparatus transmitting and receiving MAC PDU with a data check bit comprising:

a receiving section that receives the MAC PDU from another wireless communication apparatus of a transmitting origin;

a received MAC PDU determining section that performs a data check for the received MAC PDU using the data check bit and determines whether an error occurs in the MAC PDU;

a received result transmitting section that, when determining occurrence of the error, discards the MAC PDU and transmits a retransmission request for the MAC PDU to the other wireless communication apparatus, and otherwise, transmits a message indicating that the MAC PDU is normal to the other wireless communication apparatus;

a format determining section that determines whether a format of the MAC PDU is normal, and passes a result of the format determining section to a predetermined processing when the format of the MAC PDU is determined to be normal; and

a retransmission asking section that discards the MAC PDU and requests the received result transmitting section to transmit the retransmission request when the format of the MAC PDU is other than normal,

wherein the format of the MAC PDU is determined to be other than normal including when at least one of an identifier of a logical channel and an identifier of MAC control information is out of a range of the wireless communication apparatus.

2. A method to transmit and receive MAC PDU with a data check bit comprising:

receiving the MAC PDU from another wireless communication apparatus of a transmitting origin;

checking data of the received MAC PDU using a data check bit and determining whether an error occurs in the MAC PDU;

transmitting a message to the other wireless communication apparatus when the MAC PDU is normal, and discarding the MAC PDU and transmitting a retransmission request for the MAC PDU to the other wireless communication apparatus when determining the MAC PDU includes the error;

determining whether a format of the MAC PDU is incorrect or normal; and

passing a result of a format determination to a predetermined processing when the format of the MAC PDU is determined to be normal, and discarding the MAC PDU and requesting transmission of the retransmission request when the format of the MAC PDU is determined to be other than normal,

wherein the format of the MAC PDU is determined to be other than normal including when at least one of an identifier of a logical channel and an identifier of MAC control information is out of a range of a wireless communication apparatus.

3. A non-transitory computer-readable medium which when executed on a wireless communication apparatus, causes the wireless communication apparatus to execute a process comprising:

receiving a MAC PDU from another wireless communication apparatus of a transmitting origin;

checking data of the received MAC PDU using a data check bit and determining whether an error occurs in the MAC PDU;

transmitting a message to another wireless communication apparatus when the MAC PDU is normal, and discarding the MAC PDU and transmitting a retransmission request for the MAC PDU to the another wireless communication apparatus when determining the MAC PDU includes the error;

determining whether a format of the MAC PDU is normal; and

passing a result of a format determination to a predetermined processing when the format of the MAC PDU is determined to be normal, and discarding the MAC PDU and requesting transmission of the retransmission request when the format of the MAC PDU is other than normal,

wherein the format of the MAC PDU is determined to be other than normal including when at least one of an identifier of a logical channel and an identifier of MAC control information is out of a range of the wireless communication apparatus.
