Abstract: A method and apparatus is provided for a operating a radio communication system (100). The system (100) has a sequence of communication channels (205), including a reservation channel, and a channel hopping protocol for operating on the sequence (205). A hop period is defined for the channel hopping protocol. A transceiver (113) monitors the reservation channel to find an open communication slot (213), having a duration less than the channel hop period, and cyclically channel hops through the sequence of communication channels in the open slot (213). The transceiver (113) reserves the communication slot (213) for a subsequent cycle through the sequence by transmitting a reservation signal on the reservation channel.

Prioritized-routing for an ad-hoc, peer-to-peer, mobile radio access system
Peter Stanforth
- 22 Mar 2001
TL;DR: In this paper, a peer-to-peer radio access system with a series of remote terminals is described, where each remote terminal is capable of forming a link, or hop, of the routing of a call made by one of the series of terminals.

Reduction of synchronous fading effects by time hopping of user slots in TDMA frames
Sandeep Chennakeshu
- 02 May 1989
TL;DR: In this paper, a method for the reduction of synchronous fading effects in a time-diversity multiple-access communications system, in which the data to/from a particular user is to appear in a particular assigned slot, varies the position of the time slot assigned to that particular user, so that the slot has a different position in each successive frame in which that assigned slot appears.

Method for reducing synchronizing overhead of frequency hopping communications systems
George R. Oliva,Gregory Lorenzo,Kenneth J. Loffer +2 more
- 24 Aug 1994
TL;DR: In this article, the authors propose a synchronization state during which a plurality of communications can take place without re-synchronization before each separate transmission, and a synchronization period during which all radios are initially synchronized, followed by a series of acknowledgment period and transmission periods during which any unit intending to transmit is assigned a specific time slot for such transmission.
