Claims (15)

1. Basisstation (120), der er konfigureret til at synkronisere indhold ved udsendelse af data i et kommunikationsnetværk, hvilken basisstation omfatter: en modtager (1201), der er konfigureret til at modtage datasekvenser, PDLT-er; hvor hver modtaget datasekvens omfatter byte-nummererede sekvensnumre; hvilken basisstation yderligere omfatter: en transmitter (1202), der er konfigureret til at transmittere indhold af den modtagne datasekvens; og en behandlingsindretning (1203), der er konfigureret til at synkronisere transmission med en anden basisstation af indholdet under anvendelse af de byte-nummererede sekvensnumre, hvor behandlingsindretningen (1203) er konfigureret til at bestemme, om en PDU er tabt.
2. Basisstation ifølge krav 1, hvor det samme indhold sendes fra basisstationen og en anden basisstation i en samme radioressourceblok.
3. Basisstation ifølge krav 1 eller 2, hvor behandlingsindretningen er konfigureret til at bestemme, hvilken PDU eller hvilken del af en PDU der skal anvendes til at genoptage transmissionen.
4. Basisstation ifølge et hvilket som helst af de foregående krav, hvor behandlingsindretningen er konfigureret til at anvende et sekvensnummer af en efterfølgende modtaget PDU og et sekvensnummer af en sidst modtaget PDU til bestemmelse af antallet af tabte bytes af data og bestemmelse af en transmissionsfortsættelse med en efterfølgende PDU.
5. Basisstation ifølge et hvilket som helst af de foregående krav, hvor den modtagne datasekvens omfatter et pakkeniveau-sekvensnummer og byte-niveau-sekvensnummeret.
6. Basisstation ifølge et hvilket som helst af de foregående krav, yderligere omfattende en buffer (1204), der er konfigueret til at modtage datasekvenser omfattende en pakke-header og ingen brugerdatadel, hvilken pakke-header omfatter et byte-niveau-sekvensnummer, som er fastsat i henhold til virtuelle data forbundet med datasekvensen.
7. Fremgangsmåde for en basisstation (120) til indholdssynkronisering ved udsendelse af data i et kommunikationsnetværk, hvilken fremgangsmåde omfatter: at modtage datasekvenser, PDU'er, og, hvor hver modtaget datasekvens omfatter byte-nummererede sekvensnumre; og at transmittere indholdet af de modtagne datasekvenser i synkronisering med en anden basisstation under anvendelse af de byte-nummererede sekvensnumre og at bestemme, om en PDU er tabt.
8. Fremgangsmåde ifølge krav 7, omfattende mapping af indholdet til en tilsvarende radioressourceblok ved at afhænge af de byte-nummererede sekvensnumre.
9. Indretning (130) til indholdssynkronisering ved transmittering af data fra en infrastrukturknude i et kommunikationsnetværk, hvilken indretning omfatter: en behandlingsindretning (1301), der er konfigureret til at tilføje byte-nummererede sekvensnumre til en datasekvens til transmission til en basisstation; og en transmitter (1303), der er konfigureret til at transmittere datasekvenserne med byte-nummererede sekvensnumre og indhold til en flerhed af basisstationer, hvor de byte-nummererede sekvensnumre muliggør indholdssynkronisering gennem basisstationen og bestemmelse af, om en PDU er tabt.
10. Indretning ifølge krav 9, hvor en SYNC-protokol muliggør indholdssynkronisering gennem basisstationen.
11. Indretning ifølge krav 9 eller 10, hvor indretningen er konfigureret til at opnå sekvensnummeret af en efterfølgende pakke ved at forøge et sekvensnummer af en tidligere pakke med en størrelse af den tidligere pakke.
12. Indretning ifølge et hvilket som helst af kravene 9, 10 eller 11, hvor indretningen er konfigureret til at tilføje et pakkeniveau-sekvensnummer til datasekvenserne sammen med et byte-niveau-sekvensnummer.
13. Fremgangsmåde til indholdssynkronisering ved udsendelse af data i et kommunikationsnetværk, hvilken fremgangsmåde omfatter: at tilføje byte-nummererede sekvensnumre til indhold til transmission i en datasekvens til en basisstation og at transmittere datasekvenserne med byte-nummererede sekvensnumre til en flerhed af basisstationer, hvor de byte-nummererede sekvensnumre muliggør indholdssynkronisering gennem basisstationen og bestemmelse af, om en PDU er tabt.
14. Fremgangsmåde ifølge krav 13, yderligere omfattende mapping af indholdet til en tilsvarende radioressourceblok ved at afhænge af de byte-nummererede sekvensnumre.
15. Fremgangsmåde ifølge krav 13 eller 14, omfattende at bestemme, om en datasekvens er tabt, og hvilken datasekvens eller hvilken del af datasekvensen der skal genoptages efter transmission, og yderligere omfattende at anvende et sekvensnummer af en efterfølgende modtaget datasekvens og et sekvensnummer af en sidste modtaget datasekvens til bestemmelse af antallet af tabte bytes af data og bestemmelse af transmissionsfortsættelse med en efterfølgende datasekvens.
