1 [preamble]. “A method of detecting an erroneous sequence number of a status report unit in a wireless communications system, the 

method comprising:”

1 [preamble]. “A 

method of detecting 

an erroneous 

sequence number of 

a status report unit 

in a wireless 

communications 

system, the method 

comprising:”

To the extent the preamble is limiting, LG’s Stylo 6 utilizes a method of detecting an erroneous sequence 

number of a status report unit in a wireless communications system. See U.S. Patent 7,664,059 col. 6 l. 2-4 

(filed Apr. 4, 2006).

A function of the Stylo 6 when communicating over a cellular network is the automatic repeat request (ARQ) 

procedure in acknowledged mode includes retransmission procedures in the event the transmitter receives a 

negative acknowledgement (NACK) from the receiver.
US Patent No. 7,664,059: Claim 1

1 [a]. “receiving a status report unit output from a receiver of the wireless communications system;”

3

1 [a]. “receiving 

a status report 

unit output from 

a receiver of the 

wireless 

communications 

system;”

LG’s Stylo 6 receives a status report unit output from a receiver of the wireless communications system. ’059 

Patent col. 6 l. 5-6. 

A function of Stylo 6 when communicating over a cellular network is detecting a reception failure at an RLC 

receiver in acknowledge mode, then having the receiver send a NACK via a status PDU report to the transmitter. 
US Patent No. 7,664,059: Claim 1

“1 [b]. detecting whether a negatively acknowledged sequence number lies in a range of greater than or equal to a sequence number 

following a sequence number of a last in-sequence acknowledged packet of a transmitter and less than a sequence number of a next 

packet to be transmitted for the first time by the transmitter when the negatively acknowledged sequence number is detected in the 

status report unit; and”

1 [b]. “detecting 

whether a 

negatively 

acknowledged 

sequence number 

lies in a range of 

greater than or 

equal to a sequence 

number following a 

sequence number of 

a last in-sequence 

acknowledged 

packet of a 

transmitter and less 

than a sequence 

number of a next 

packet to be 

transmitted for the 

first time by the 

transmitter when 

the negatively 

acknowledged 

sequence number is 

detected in the 

status report unit; 

and”

LG’s Stylo 6 detects whether a negatively acknowledged sequence number lies in a range of greater than or 

equal to a sequence number following a sequence number of a last in-sequence acknowledged packet of a 

transmitter and less than a sequence number of a next packet to be transmitted for the first time by the 

transmitter when the negatively acknowledged sequence number is detected in the status report unit. ’059 

Patent col. 6 l. 7-14.

A function of Stylo 6 when communicating over a cellular network is having the transmitter receive the 

STATUS PDU report, detect whether a NACK SN is received, and detect whether the SN is within the range 

VT(A) <= SN < VT(S) as a response. 
US Patent No. 7,664,059: Claim 1

1 [c]. “detecting that the status report unit comprises an erroneous sequence number when the negatively acknowledged sequence 

number is not in the range.”

5

1 [c]. “detecting 

that the status 

report unit 

comprises an 

erroneous sequence 

number when the 

negatively 

acknowledged 

sequence number is 

not in the range.”

LG’s Stylo 6 detects that the status report unit comprises an erroneous sequence number when the negatively 

acknowledged sequence number is not in the range. ’059 Patent col. 6 l. 15-17. 

A function of Stylo 6 when communicating over a cellular network is having the transmitter discard the 

corresponding PDU when the transmitter receives the invalid SN. When a PDU contains an SN outside the 

range VT(A) <= SN < VT(S), the serial number is invalid and is considered erroneous.
