Digital control channels having logical channels for multiple access radiocommunication
First Claim
1. A method of communicating information to a remote station comprising the steps of:
- grouping the information into a plurality of successive time slots on a radio carrier signal;
grouping the time slots into a plurality of successive superframes;
grouping the successive superframes into a plurality of successive hyperframes, wherein at least two successive superframes are grouped into each hyperframe; and
assigning one of the time slots in each of a plurality of said plurality of successive superframes to the remote station, the assigned time slot being for sending a paging message to the remote station;
wherein information sent in the assigned time slot of a superframe in a hyperframe is repeated in the assigned time slot in all other superframes in that hyperframe.

Abstract
A communications system in which information is transmitted in successive time slots grouped into a plurality of superframes which are, in turn, grouped into a plurality of hyperframes. A remote station is assigned to one of the time slots in each of the superframes for paging the remote station, each hyperframe including at least two superframes, and the information sent in the assigned time slot in one superframe in each hyperframe is repeated in the assigned time slot in the other superframe(s) in each hyperframe. Each superframe can include a plurality of time slots used for sending paging messages to remote stations, grouped into a plurality of successive paging frames, and the time slot to which the remote station is assigned is included once in every paging frame. Also, each superframe may include time slots comprising a logical channel for broadcast control information and time slots comprising a logical paging channel. Information sent in the assigned time slot may direct the remote station to read the broadcast control information, and the information may have been encoded according to an error correcting code and include a plurality of bits having polarities that are inverses of cyclic redundancy check bits produced by the encoding. Also, the broadcast control information may comprise special messages that are included in respective time slots comprising a logical special message channel, the time slots of the special message channel may be grouped in successive SMS frames, and the SMS frames may be synchronized to start with a start of a superframe.

11. In a radio communication system, a base station for communicating information to a remote station comprising:
-
means for grouping the information into a plurality of successive time slots, the time slots being grouped in a plurality of successive superframes and the successive superframes being grouped in a plurality of successive hyperframes, a transmitter for sending the time slots on a radio carrier signal; wherein at least two successive superframes are grouped into a hyperframe, and one of the time slots in each of the at least two successive superframes is assigned to the remote station, the assigned time slot being for sending a paging message to the remote station, and the transmitter sends information sent in the assigned time slot in one superframe in a hyperframe in the assigned time slot in all other superframes in that hyperframe. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. In a radio communication system, a remote station for receiving information sent by a base station in a plurality of successive time slots on a radio carrier signal comprising:
-
a receiver for receiving the radio carrier signal; means for processing the information in the time slots on the received carrier signal, wherein the time slots are grouped in a plurality of successive superframes;
the successive superframes are grouped in a plurality of successive hyperframes;
at least two successive superframes are grouped in a hyperframe;
one of the time slots in each of the at least two superframes is assigned to the remote station, the assigned time slot being for sending a paging message to the remote station; and
information sent in the assigned time slot in one superframe in a hyperframe is repeated in the assigned time slot in all other superflames in that hyperframe. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
