  • Publication number: 20070066330
    Abstract: Fast macrodiversity switching (FMS) of channels that employ interleaving. The fast macrodiversity switching dynamically switches radio links used for traffic and control channels for a mobile station among a number of base transceiver stations (BTS) without switching the radio resource, using the same frequency and time slot combination (TDMA) in an environment where interleaving is occurring. The fast macrodiversity switching of channels and interleave processing is under control of an interleave manager which is distributed among zone managers. The control by the host and assistant zone managers includes switching down-link signals to and up-link signals from mobile stations among base transceiver stations which include broadcast channels (non-switched) and dedicated (switched) channels that employ interleaving. The dedicated channels are switched as frequently as a signal switch time which can be the frame rate of the up-link signals.

  • Publication number: 20070042786
    Abstract: Dynamic allocation of communication channels among communication units (CU) in a communications system. Dynamic channel allocation employs a reservation set for reserving channels and an allocation set corresponding to the reservation set for receiving allocated channels. The reservation set and the allocation set are changed dynamically as a function of network parameters to control the dynamic channel operation. Reservation set information is broadcast downlink to multiple users to reserve an allocation set of uplink radio resources for specific ones of the users. The system uses a modification of the packet data channel (PDCH) of a GPRS/EGPRS or EDGE system which employs an Uplink Status Flag (USF) on each PDCH downlink radio block. The downlink reservation set information is commonly received by all users in the group of users. Allocation delay, bandwidth efficiency and other system parameters are optimized.

  • Publication number: 20060153147
    Abstract: A communication system for communication using wireless signals in a fast macrodiversity switching environment. The wireless signals include downlink signals to and uplink signals from mobile stations where the wireless signals have bursts in time slots. In the communication system, a plurality of transceiver stations have broadcast channels (non-switched) and dedicated channels. (switched) for the wireless signals. A zone manager controls the fast macrodiversity switching of bursts in dedicated channels among transceiver stations. The fast macrodiversity switching causes the bursts to have time shifts that are of a magnitude to cause unwanted burst overlap. A macro-diversity timing control controls the timing of bursts, to reduce burst overlap, in dedicated channels that have been dynamically switched timing problem.
