Abstract
Abstract A method for data related downlink signaling including selectively tailoring the UE ID to create a UE ID value, which is then added to a data field to create a data mask. This data mask is then further processed as the CRC field and transmitted with the data burst to provide CRC-related functions. An alternative embodiment discloses initializing a CRC generator with UE identification prior to CRC generation. This implicitly includes the UE ID within the CRC without requiring additional overhead signaling.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
125 words
A system for transmitting a communication burst from a first communicating unit to a second communicating unit; the system comprising: at said first communicating unit: a cyclic redundancy check (CRC) generator for receiving data and generating a CRC; a first combiner for combining said CRC with an identification of the second communicating unit to generate a mask; and a transmitter for transmitting the burst comprising said mask and said data; and at said second communicating unit: a memory for storing the identification of the second communicating unit; a receiver for receiving said communication burst including said mask and said data; a second combiner for combining said mask with said stored identification to recover the CRC; and means for determining whether said recovered CRC is valid.
Claim 2
Independent Claim
125 words
A system for transmitting a communication burst from a first communicating unit to a second communicating unit; the system comprising: at said first communicating unit: a cyclic redundancy check (CRC) generator for receiving data and generating a CRC; a first combiner for combining said CRC with an identification of the second communicating unit to generate a mask; and a transmitter for transmitting the burst comprising said mask and said data; and at said second communicating unit: a memory for storing the identification of the second communicating unit; a receiver for receiving said communication burst including said mask and said data; a second combiner for combining said mask with said stored identification to recover the CRC; and means for determining whether said recovered CRC is valid.
Claim 3
Dependent Claim
15 words
The system of claim 1 , wherein said first and second combiners are modulo-2 adders.
Claim 4
Independent Claim
128 words
A system for transmitting a communication burst from a first communicating unit to at least a second communicating unit; the second communicating unit being associated with an identification number; the system comprising: at said first communicating unit: a cyclic redundancy check (CRC) generator for receiving data and generating a CRC; a combiner for combining said CRC with the identification number to generate a mask; and a transmitter for transmitting a communication burst comprising said mask and said data; and at said second communicating unit: a memory for storing said identification number; a receiver for receiving said communication burst including said mask and said data; a combiner for combining said mask with said stored identification number to recover the CRC; means for determining whether said recovered CRC is valid.
Claim 5
Independent Claim
128 words
A system for transmitting a communication burst from a first communicating unit to at least a second communicating unit; the second communicating unit being associated with an identification number; the system comprising: at said first communicating unit: a cyclic redundancy check (CRC) generator for receiving data and generating a CRC; a combiner for combining said CRC with the identification number to generate a mask; and a transmitter for transmitting a communication burst comprising said mask and said data; and at said second communicating unit: a memory for storing said identification number; a receiver for receiving said communication burst including said mask and said data; a combiner for combining said mask with said stored identification number to recover the CRC; means for determining whether said recovered CRC is valid.
Claim 6
Dependent Claim
26 words
The system of claim 3 , further including at least a third communication unit, whereby said third communication unit is also associated with said identification number.
Claim 7
Dependent Claim
29 words
The system of claim 3 , further including a plurality of communication units, wherein only a portion of said plurality of communication units is associated with said identification number.
Claim 8
Independent Claim
110 words
A system for transmitting a communication burst from a first communicating unit to a second communicating unit; the second unit being associated with an identification; the system comprising: at said first communicating unit: a combiner for receiving data and combining the data with an identification field including said identification to generate a mask; a cyclic redundancy check (CRC) generator for receiving the mask and generating a CRC; and a transmitter for transmitting a communication burst comprising said CRC and said data; and at said second communicating unit: a receiver for receiving said communication burst including said CRC and said data; and means for determining whether said recovered CRC is valid.
Claim 9
Independent Claim
110 words
A system for transmitting a communication burst from a first communicating unit to a second communicating unit; the second unit being associated with an identification; the system comprising: at said first communicating unit: a combiner for receiving data and combining the data with an identification field including said identification to generate a mask; a cyclic redundancy check (CRC) generator for receiving the mask and generating a CRC; and a transmitter for transmitting a communication burst comprising said CRC and said data; and at said second communicating unit: a receiver for receiving said communication burst including said CRC and said data; and means for determining whether said recovered CRC is valid.
Claim 10
Dependent Claim
46 words
The system of claim 6 , wherein said data comprises a data block and wherein said identification field includes both said identification and a plurality of additional bits such that the length of the identification field is the same as the length of the data block.
Claim 11
Dependent Claim
18 words
The system of claim 7 , wherein at least a portion of said additional bits includes said identification.
Claim 12
Independent Claim
101 words
A method for transmitting a data burst from a first unit to a second unit comprising: at said first unit: receiving data for transmission; generating a cyclic redundancy check (CRC) based upon said data; combining the CRC with an identification of the second unit to generate a mask; appending the mask onto the data to form a data burst; and transmitting the data burst; and at said second unit: receiving said data burst; retrieving the identification of the second unit from memory; and combining the retrieved identification with said mask to generate said CRC; and determining whether said CRC is valid.
Claim 13
Independent Claim
101 words
A method for transmitting a data burst from a first unit to a second unit comprising: at said first unit: receiving data for transmission; generating a cyclic redundancy check (CRC) based upon said data; combining the CRC with an identification of the second unit to generate a mask; appending the mask onto the data to form a data burst; and transmitting the data burst; and at said second unit: receiving said data burst; retrieving the identification of the second unit from memory; and combining the retrieved identification with said mask to generate said CRC; and determining whether said CRC is valid.
