Claims (11)

1. Fremgangsmåde i en brugerterminal (120, 130, 600) i et cellulært kommunikationssystem (100), omfattende at anvende (505) en første tidsfremrykningsværdi (Ttai) på transmissioner til en styreknude (140), at transmittere (402) en random access-præambel (MSG 1) i en konfliktbaseret random access-procedure til anmodning (510) om kommunikation med styreknuden (140), at modtage (515), fra styreknuden, et random access-svar (MSG 2) med en anden tidsfremrykningsværdi (Tta2), hvor fremgangsmåden er kendetegnet ved; at ignorere den anden tidsfremrykningsværdi (Tta2), når den første tidsfremrykningsværdi er gyldig og derved anvende (523, 524) tidsfremrykningsværdi på transmissioner efter modtagelse af random access-svaret, hvor den første tidsfremrykningsværdi er forbundet med en timer og er gyldig, når timeren kører.
2. Fremgangsmåde ifølge krav 1, endvidere omfattende at starte timeren ved modtagelse af den første tidsfremrykningsværdi.
3. Fremgangsmåde ifølge et af de foregående krav, anvendt i et LTE-system, Long Term Evolution, således at brugerterminalen (120, 130) er en LTE-bru-gerindretning, og styreknuden (140) er en LTE-eNodeB.
4. Fremgangsmåde ifølge krav 3, der anvendes i en LTE-random acces-pro-cedure.
5. Fremgangsmåde ifølge krav 1, hvor transmission af random access-præ-amblen til styreknuden som en del af den konfliktbaserede random access-procedure omfatter: at fastslå at der ikke allokeres ressourcer til brugerterminalen med henblik på at tilvejebringe kontakt til styreknuden; og som reaktion på fastslåelsen af, at der ikke allokeres ressourcer til brugerterminal, at transmittere random access-præamblen på en fysisk random access-kanal til styreknuden.
6. Fremgangsmåde ifølge krav 1 og 5, hvor transmission af random access-præamblen til styreknuden som en del af den konfliktbaserede random access-procedure omfatter: vilkårligt at vælge en af en flerhed af præambler, der er tilgængelige til konfliktbaseret random access; og at transmittere den vilkårligt valgte random access-præambel til styreknuden.
7. Fremgangsmåde ifølge krav 1, hvor anvendelse (505) af den første tidsfremrykningsværdi (Ttai) på transmissioner til en styreknude (140) omfatter at starte transmission af data på et tidspunkt, der er forskudt ifølge den første tidsfremrykningsværdi i forhold til en nominel transmissionstid, der er forbundet med styreknuden.
8. Brugerterminal (600) i et cellulært kommunikationssystem, omfattende midler (640, 650) til anvendelse af en første tidsfremrykningsværdi på dens transmissioner til en styreknude, og indrettet til at transmittere (640, 630, 610) en random access-præambel (MSG 1) i en konfliktbaseret random access-procedure til anmodning om kommunikation med styreknuden, og midler (610, 620) til modtagelse af et random access-svar (MSG 2) med en anden tidsfremrykningsværdi fra styreknuden som svar, kendetegnet ved at være indrettet til at ignorere den anden tidsfremrykningsværdi, når den første tidsfremrykningsværdi er gyldig og derefter anvende den første tidsfremrykningsværdi på transmissioner efter modtagelse af random access-svaret, hvor brugerterminalen endvidere omfatter en timer, der er forbundet med den første tidsfremrykningsværdi, og indrettet til at fastslå, at den første tidsfremrykningsværdi er gyldig, når timeren kører.
9. Brugerterminal ifølge krav 8, der er indrettet til at starte timeren ved modtagelse af den første tidsfremrykningsværdi.
10. Brugerterminalen ifølge krav 9, der er indrettet til at lade timeren fortsætte med at køre efter modtagelse af random access-svaret.
11. Brugerterminal (600) ifølge et af kravene 8-10, der er indrettet til anvendelse i et LTE-system, Long Term Evolution, som en LTE-brugerindretning.
