Abstract: A method allowing wireless communications devices to scan for critical transmissions while transmitting on a conventional time division multiple access channel (TDMA) is disclosed. The TDMA channel is divided into a plurality of slots, each slot capable of carrying audio, video, control, and/or data transmissions. A first slot is used by a first communication device, while a second slot is used by a second communication device. The first communication device transmits at least one burst of information from a first transmission in a first slot. The first communication device switches to a second slot and reads at least one signaling information segment embedded in a second transmission that is being transmitted in the second slot. The first communication device determines to terminate the first transmission in order to receive the second transmission, or to switch back to the first slot and repeat the steps of transmitting, switching, reading and determining.

A generation of said correction signal (?(x)) is based on a plurality of base functions (?1, ?2, . . . , ?N?1), and said range of input amplitudes (r0, . . . , rM?1) is divided into intervals (r0,r1),(r1,r2), . . . ,(rM?2,rM?1), wherein each of said base functions (?1, ?2, . . . , ?N?1) contributes to said correction signal (?(x)) in a limited number of intervals ((r0,r1),(r1,r2), . . . ,(rM?2,rM?1)). Thus it is possible to change parts of the correction signal by adapting some of said base functions without influencing the whole correction signal.

Abstract: A method and system for scanning a TDMA channel by a subscriber unit in a wireless communications landscape 100 is disclosed. The subscriber unit locks onto a channel that is preprogrammed in the subscriber unit. A base radio transmits a control message to the subscriber unit. The control message informs the subscriber unit of activity present on the channel. The subscriber unit receives and decodes the control message to determine whether there is activity on the channel. If there is, the subscriber unit determines whether the activity is of interest. If it is, then the subscriber unit remains on the channel to receive the activity present on the channel.

Based on the first requested call type, the fixed end device dynamically sets a first slotting structure as an existing slotting structure for the inbound and outbound channels. When a second requested call type is received, the fixed end determines whether to grant or deny the second requested call type and/or whether to maintain or dynamically change the existing slotting structure.
