Abstract
A method of transmitting an overhead message via a control channel which has at least one slot is disclosed. More specifically, a base station (BS) transmits an overhead slot cycle index for providing the overhead message to a mobile station (MS) and thereafter, receives the overhead slot cycle index and determining an overhead slot cycle. Furthermore, the BS transmits the overhead message on a first slot of each overhead slot cycle according to a variable duration of the slot, and then receives the overhead message from the first slot of each overhead slot cycle according to the variable duration of the slot.
Claims13
A method of transmitting an overhead message via a control channel having at least one slot, the method comprising:
- transmitting an overhead slot cycle index to allow a mobile station (MS) to determine an overhead slot cycle;
- receiving information of the overhead slot cycle determined by the MS based on a variable duration of the slot and the overhead slot cycle index, wherein the overhead slot cycle is repeatedly used;
- transmitting the overhead message on the first slot of each overhead slot cycle provided from the received information,
- wherein the first slot of each overhead slot cycle is determined by any of a first equation of
- ⌊
- t
- 2
- ⌋
-
- mod
-
-
- (
- B
- +
- 1
- )
- =
- 0
- wherein the variable duration of the slot is 40 ms, a second equation of
- ⌊

-
- mod

-
- (

- wherein the variable duration of the slot is 80 ms, or a third equation of
- ⌊
- t
- 8
- ⌋
-
- mod
-
-
- (
- B
- +
- 1

- =
- 0
- wherein the variable duration of the slot is 160 ms.
A method of receiving an overhead message via a control channel having at least one slot, the method comprising:
- receiving an overhead slot cycle index from a base station (BS) to determine an overhead slot cycle;
- determining the overhead slot cycle based on a variable duration of the slot and the overhead slot cycle index received from the BS, wherein the first slot of each overhead slot cycle is determined by any of
- a first equation of
- └t/2┘mod (B+1)=0
- wherein the variable duration of the slot is 40 ms, a second equation of
- └t/4┘mod (B+1)=0
- wherein the variable duration of the slot is 80 ms, or a third equation of
- └t/8┘mod (B+1)=0
- wherein the variable duration of the slot is 160 ms;
- transmitting to the BS information of the determined overhead slot cycle;
- and
- receiving the overhead message via a first slot of each overhead slot cycle.
