Abstract
The invention relates to a technique of performing a random access procedure over a radio interface (106) in a mobile terminal (102). A method embodiment or the random access procedure as performed in the mobile terminal comprises the steps of selecting an access time slot for transmission of an access burst (112) over the radio interface; and setting an access bandwidth for transmission of the access burst, wherein the access bandwidth is set smaller than an available transmission bandwidth associated with the radio interface.
Claims21
A method of performing a random access procedure over a radio interface (106), the method comprising the steps of:
- selecting (204) an access time slot for transmission of an access burst (112) over the radio interface;
- and
- setting (206) an access bandwidth (BWRACH) for transmission of the access burst;
- wherein the access bandwidth is set smaller than an available system transmission bandwidth for uplink transmissions associated with the radio interface.
A method of providing a random access channel for a radio interface (106), the method comprising the steps of:
- defining (224) access time slots for the random access channel;
- and
- setting (226) an access bandwidth (BWRACH) for an access request;
- wherein the access bandwidth is set smaller than an available system transmission bandwidth for uplink transmissions associated with the radio interface.
A mobile terminal (102, 120) adapted for performing a random access procedure over a radio interface (106), the terminal comprising:
- a time slot component (122) adapted for selecting an access time slot for transmission of an access burst (112) over the radio interface;
- and
- a bandwidth component (124) adapted for setting an access bandwidth (BWRACH) for transmission of the access burst;
- wherein the bandwidth component is adapted for setting the access bandwidth smaller than an available system transmission bandwidth for uplink transmissions associated with the radio interface.
A radio base station (104, 140) adapted for providing a random access channel for a radio interface (106), the radio base station comprising:
- a time slot component (148) adapted for defining an access time slot for the random access channel;
- and
- a bandwidth component (150) adapted for setting an access bandwidth (BWRACH) for an access request;
- wherein the bandwidth component is adapted for setting the access bandwidth smaller than an available system transmission bandwidth for uplink transmissions associated with the radio interface.
