Motivations Efficient MAC PDU Header –6-byte fixed MAC header with HCS => Small overhead. –Single type for GMH with payload => Multiple PDU types Efficiently Handling MAC PDU Payload –PDU construction per connection => Multiplexing –Overhead for short data, i.e. VoIP packet. => Small overhead GMH + Fragmentation SH Retransmission and Fragmentation –NO ARQ on unidirectinal MAC management message => ARQ –BSN for ARQ-enabled connection and FSN for ARQ-disabled connection => Use unified numbering scheme

MAC PDU Header No MAC CRC if PHY CRC exists –Removal of HCS in GMH Flow ID to identify a connection within a user Encryption Control –Removal of the EC (Encryption Control) field –EC&Key Sequence=0 means “No Encryption” –Three encryption identifier, EC&Key Sequence=1,2,3 Type encodings –Five indications for ARQ Feedback Payload, Fragment SH, Packing SH, Extended Type, and Grant management SH

MAC PDU Types Three MAC PDU Types –Optimize MAC PDU to Payloads –Generic MAC PDU Handling MAC Payload to 2048 bytes Packing SH; Fragment SH; Extended SH; Grant Management SH for UL –Light MAC PDU Handling short size data to 128 bytes (i.e. VoIP) Small overhead No SH –All the information for PDU handling is in Light MAC PDU header –Control MAC PDU Carry control information with fixed-sized PDU

Control PDU Payloads (Examples) Null Padding Aggregated bandwidth request Average DL CINR Preferred DL TF UL transmit power Band CINR: BITMAP + n CQIs Differential Band CINR Post-Rx CINR I: CQI for MS Post-Rx CINR II: 4 CQIs Precoding I: Codebook + CQI Precoding II: Codebook + 4 CQIs BR and UL transmit power BR and average DL CINR SDU SN report Incremental bandwidth request Rate change request for ertPS CINR standard deviation MIMO type Anchor change request: BSID CQICH allocation request NBR CINR and RSSI UGS grant management: SI+PM+FLI+FL ERTPS grant management: PSI+PSOBR+FLI+FL BR and sleep control PHY channel report: Tx Power + Headroom CINR statistics: Average + Standards BR and NACK request

SDU Handling Use a BSN for both ARQ-enabled and ARQ-disabled connections –Unified numbering with BSN Allow MAC PDU to multiplex DATA from other connection with packing SH –Insert the indication, “Flow ID Included (or not)” –If set, Flow ID is added prior to DATA. Allow unidirectional MAC management messages to be retransmitted with ARQ function –Ex) EAP Transfer Encrypt Fragmented SDU or Packing SDUs for relay function –No encryption of Subheaders.

Numerical Results of The Example

SDD Texts 10.X Construction of MAC PDU A MAC PDU header contains minimal information required for handling MAC PDU such as PDU type, Flow ID, Encryption Control, and Type Encoding, Length, and etc. Multiple PDU formats are designed to optimize overhead according to payloads. Generic MAC PDU and Control MAC PDU are to manage full PDU handling functions and to carry uplink control functions for uplink, respectively. Additionally Light MAC PDU with small overhead is to transport short data for VoIP, etc. Encryption on MAC PDU is applied only to MAC SDUs and/or fragments except subheaders including fragmentation and packing subheaders. All the SDUs and/or fragments are numbered by by block sequence numbers(BSNs). A MAC PDU may concatenate SDUs and/or fragments from other flows, which Flow ID is added to packing SH. Unidirectional MAC management messages may be retransmitted using ARQ function.
