![]() ![]() The number of such message that can be comprised in S-PDU has determined the length (bit) of the type identifier field used among the S-PDU.For example, the length of such type identifier field can be determined according to following formula: 4 illustrates the bitmap message that is used for the such field of having of S-PDU in first embodiment of the present invention. H04L1/1671- Details of the supervisory signal the supervisory signal being transmitted together with control informationĮxemplary hereto embodiment is used for making the basic messae of feedback response minimum to construct in such a way in the ARQ agreement.Use a bit map method in this embodiment, be included in the sequence number that sequence number SN among the good S-PDU of structure illustrates the D-PDU of arbitrary mistake in this group sequence number (not necessarily first).The state of later sequence number illustrates in bitmap.Though in this exemplary embodiment, adopted the sequence number of first wrong D-PDU, should be understood that in this bitmap scheme and also can adopt (in this sequence number sets) any D-PDU.In this case, bitmap also must comprise the state (0 or 1) of the sequence number that is comprised among the good S-PDU of structure.Like this, " bitmap " message can produce with type identifier field, first sequence number (FSN) field, bitmap lengths field and a bitmap field.Fig.the acknowledgement message defining a range of identifiers, e.g. H04L1/1621- Group acknowledgement, i.e. ![]() H04L1/1614- Details of the supervisory signal using bitmaps.H04L1/18- Automatic repetition systems, e.g.the acknowledgement message consisting of a list of identifiers, e.g. H04L1/1628- List acknowledgements, i.e.H04L1/1607- Details of the supervisory signal.H04L1/16- Arrangements for detecting or preventing errors in the information received by using return channel in which the return channel carries supervisory signals, e.g.H04L1/12- Arrangements for detecting or preventing errors in the information received by using return channel.H04L1/00- Arrangements for detecting or preventing errors in the information received.H04L- TRANSMISSION OF DIGITAL INFORMATION, e.g.Anticipated expiration legal-status Critical Status Ceased legal-status Critical Current Links Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
