摘要:
A communication system using fast macrodiversity switching (FMS) and frequency hopping (FH) for wireless signals including downlink signals to and uplink signals from mobile stations. Frequency hopping sequences are determined for the uplink and downlink signals for the mobile stations. A plurality of transceiver stations employ broadcast channels and dedicated channels for communications with the mobile stations. A zone manager controls fast macrodiversity switching of dedicated channels among the mobile stations while broadcast channels remain unswitched. The zone manager extracts frequency hopping information to form predictions of dedicated channel collisions, and based upon the predictions, controls the dynamic switching of dedicated channels to avoid collisions.

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. The switch time is typically less than 1 second for mobile stations in a GSM system. The interleave processing is implemented in a GSM wireless system for TCH/FS Processing, FACCH/FS Processing and SACCH/FS Processing.

摘要:
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.
摘要:
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.
