Logical channel prioritization and data block preparation

A non-transitory computer readable medium having computer readable instructions stored thereon which, when executed by a processing circuit, cause the processing circuit to perform a method for data transmission prioritization in a communication device, the method comprising:

• receiving multiple streams of data units, each stream of data units having a prioritized bit rate (PBR) for maintaining a quality of service (QoS) level for the respective stream, a priority value, and a variable (Bj) representing a number of bits that are to be prioritized for transmission of data units of the respective stream, wherein the variable (Bj) is incremented for each transmission time interval (TTI) at the respective PBR;
• allocating transmission resources to streams having a variable (Bj) larger than zero in an order based on the priority values for transmission of data units during a TTI up to a size of available data units in the respective stream, or a size of available transmission resources, whichever is smaller;
• and
• allocating remaining transmission resources to streams having a variable (Bj) smaller than zero in an order based on the priority values for transmission data units during the TTI up to a size of available data units in the respective stream, or a size of available transmission resources, whichever is smaller.

A method for data block preparation prior to knowledge of transmission resources at a communication device, comprising:

• receiving streams of data units;
• preparing a first data block including data units for transmission in a transmission time interval (TTI) prior to knowledge of transmission resources granted for the TTI;
• receiving a grant of transmission resources for the TTI;
• determining a portion of the first data block to fit a second data block having a size determined according to the grant of transmission resources for the TTI;
• and
• processing and transmitting the second data block including the determined portion of the first data block.

A communication device, comprising circuitry configured to:

• receive streams of data units;
• prepare a first data block including data units for transmission in a transmission time interval (TTI) prior to knowledge of transmission resources granted for the TTI;
• receive a grant of transmission resources for the TTI;
• determine a portion of the first data block to fit a second data block having a size determined according to the grant of transmission resources for the TTI;
• and
• process and transmit the second data block including the determined portion of the first data block.
