Flexible Radio Link Control Packet Data Unit Length

A method performed by a first device in a High Speed Downlink Packet Access environment said method comprising:

• generating a High Speed Downlink Shared Channel data frame that includes a plurality of blocks of packet data units, a first block of the plurality of blocks including packet data units of a first length and a second block of the plurality of blocks including packet data units being of a different, second length;
• transferring the High Speed Downlink Shared Channel data frame to a second device;
• and
• wherein the High Speed Downlink Shared Channel data frame further includes, for each block of the plurality of blocks, a first information element that indicates a length of the one or more packet data units in the each block and a second information element that indicates a quantity of packet data units in the each block.

A device comprising:

• a processing system adapted to generate a High Speed Downlink Shared Channel data frame that includes a plurality of blocks of packet data units, a first block of the plurality of blocks including packet data units of a first length and a second block of the plurality of blocks including packet data units of a second, different length;
• and
• an Iub interface adapted to transfer the High Speed Downlink Shared Channel data frame;
• and
• wherein the High Speed Downlink Shared Channel data frame includes, for each block of the plurality of blocks, a first information element that indicates a length of each packet data unit in the each block and a second information element that indicates a quantity of packet data units in the each block.

A method, performed by a base station in a High Speed Downlink Packet Access environment, said method comprising:

• receiving a High Speed Downlink Shared Channel data frame from a radio network controller, the High Speed Downlink Shared Channel data frame including a packet data unit and a logical channel identifier;
• identifying, in response to receiving the High Speed Downlink Shared Channel data frame, a priority queue based on the logical channel identifier;
• and
• storing the packet data unit in the identified priority queue.

A device comprising:

• a priority queue adapted to store packet data units;
• an Iub interface adapted to receive a High Speed Downlink Shared Channel data frame, the High Speed Downlink Shared Channel data frame including a packet data unit and a logical channel identifier;
• and
• a processing system adapted to identify the priority queue based on the logical channel identifier, and
• a memory adapted to store the packet data unit in the priority queue.

A method performed by a first device in a High Speed Downlink Packet Access environment, said method comprising:

• receiving a High Speed Downlink Shared Channel capacity Allocation control frame from a second device, the High Speed Downlink Shared Channel Capacity Allocation control frame including a first value representing a first number of packet data unit octets that the first device is permitted to transmit during a High Speed Downlink Shared Channel interval;
• generating, in response to receiving the High Speed Downlink Shared Channel Capacity Allocation control frame, a High Speed Downlink Shared Channel data frame that includes a second number of packet data unit octets, the second number being equal to or less than the first number;
• and
• transferring the High Speed Downlink Shared Channel data frame to the second device in an interval.

A method comprising:

• generating, at a first device, a control message, the control message including information identifying one or more High Speed Downlink Channel framing protocol types supported by the first device;
• transferring the control message to a second device;
• selecting, at the second device, a High Speed Downlink Channel framing protocol type in response to receiving the control message;
• generating, at the second device, a response message, the response message including information identifying the selected High Speed Downlink Channel framing protocol type;
• transferring the response message to the first device;
• and
• transferring, via the first device, a High Speed Downlink Channel data frame of the selected framing protocol.
