Method and apparatus for processing padding buffer status reports
First Claim
1. A method of constructing a data unit to include control information, the method comprising:
- receiving one or more service data units (SDUs) from an upper layer;
generating a protocol data unit (PDU) using the received one or more SDUs, wherein the PDU includes a header, one or more control elements, the received one or more SDUs or a number of available padding bits; and
transmitting the generated PDU to a receiving side,wherein the header includes a plurality of sub-headers, wherein each of the plurality of sub-headers corresponds to a received SDU, a control element or padding,wherein the one or more control elements are placed before the received one or more SDUs,wherein the number of available padding bits is equal to or greater than the number of bits associated with a short buffer status Report (BSR) plus a corresponding sub-header and less than the number of bits associated with a long BSR plus a corresponding sub-header,wherein one of the one or more control elements has a corresponding sub-header that comprises a logical channel identification (LCID) field indicating that a BSR is included in the one control element,wherein the LCID field comprises a value corresponding to a predefined BSR other than a short BSR and a long BSR,wherein the predefined BSR has a format that is equivalent to the short BSR, andwherein the value indicates that there is data associated with more than one logical channel group.

Abstract
A method and system for processing buffer status reports (BSRs) such that when BSR triggering is performed, the size(s) of the necessary sub-header(s) are also to be considered together in addition to the BSR size. The steps of checking whether any padding region is available in a MAC PDU that was constructed, comparing the number of padding bits with the size of the BSR plus its sub-header, and if the number of padding bits is larger than the size of the BSR plus its sub-header, triggering BSR are performed. Doing so allows the sub-header(s) to be inserted or included into the MAC PDU or transport block (TB) or other type of data unit.

6. A mobile communication apparatus, comprising:
-
a protocol entity adapted to receive one or more service data units (SDUs) from an upper layer;
to generate a protocol data unit (PDU) using the received one or more SDUs, wherein the PDU includes a header one or more control elements, the received one or more SDUs or a number of available padding bits; and
to transmit the generated PDU to a receiving side,wherein the header includes a plurality of sub-headers, wherein each of the plurality of sub-headers corresponds to a received SDUa control element or padding, wherein the one or more control elements are placed before the received one or more SDUs, wherein the number of available padding bits is equal to or greater than the number of bits associated with a Short Buffer Status Report (BSR) plus a corresponding sub-header and less than the number of bits associated with a Long BSR plus a corresponding sub-header, wherein one of the one or more control elements has a corresponding sub-header that comprises a logical channel identification (LCID) field indicating that a BSR is included in the PDU, wherein the LCID field comprises a value identifying the BSR is different from a Short BSR and a Long BSR, wherein the predefined BSR has a format that is equivalent to the short BSR, and wherein the value indicates that there is data associated with more than one logical channel group. - View Dependent Claims (7, 8, 9, 10)
