Multi-Beam Cellular Communication System
20200170014 · 2020-05-28 · ·

A cellular communication system comprising a plurality of geographically spaced base stations (2) each of which comprise an antenna arrangement (4, 6, 8) per base station sector, each of which antenna arrangements has an antenna element for generating an array of narrow beams (10, 12, 14) covering the sector. Timeslots are simultaneously transmitted over each of the beams so as to generate successive sets of simultaneously transmitted timeslots per sector. The timeslots are each split into multiple orthogonal codes, for example Walsh codes. The communication system additionally comprising a scheduling device (31) for allocating for successive sets of timeslots common overhead channels, including a common pilot channel, which are allocated to the same sub-set of codes of each timeslot in the set. For successive sets of timeslots different data traffic is allocated to the same sub-set of codes of each timeslot in the set. This effectively generates a sector wide antenna beam carrying the common overhead channels and a plurality of narrow beams each of which carry different data traffic. Inter-beam interference is addressed by the application of Adaptive Modulation and Coding and by an inter-beam handoff scheme. The handoff scheme ensures that when an end user equipment is located in a cusp region between adjacent beams the antenna arrangement simultaneously transmits data traffic to that mobile station on at least both of the adjacent beams.

Managing wireless resources

Various embodiments provide for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.

Coded antenna arrays and associated methods, apparatus and systems are disclosed. Signals transmitted by a client device are received at a plurality of antennas or antenna elements in an antenna array. The received signals are coded using codes such as orthogonal codes and pseudorandom number sequences under which the codes are selected to enable extraction of individual received signals.

Use of multiple client devices is also supported, with the receiver circuitry further configured to filter out signals received from individual client systems and calculate the phase and magnitude of the signals as received at each antenna. The signal phase and magnitude may be used for wireless transmission of power to clients by a wireless power transmission system.
