INFRASTRUCTURE EQUIPMENT, MOBILE COMMUNICATIONS NETWORK, SYSTEM AND METHOD

摘要

An infrastructure equipment forming part of a mobile communications network includes a transmitter configured to transmit signals to communications devices via a wireless access interface, a receiver configured to receive signals transmitted from the communications devices via the wireless access interface, and a controller. The controller controls the transmitter and receiver across a first frequency bandwidth divided in time into plural frames, to form one of plural cells of the mobile communications network, each cell allocated a cell identifier by the mobile communications network. The controller and transmitter transmit in one or more of the frames a synchronization sequence providing an indication of one of the cell identifiers. A relative temporal location of the synchronization sequence within the frame provides the communications devices with an indication of the cell identifier which can be combined with detecting the synchronization sequence to improve estimate of the cell identifier for the cell.

1. An infrastructure equipment for forming part of a mobile communications network, the infrastructure equipment comprising:
a transmitter configured to transmit signals to communications devices via a wireless access interface, a receiver unit configured to receive signals transmitted from communications devices via the wireless access interface, and a controller configured to control the transmitter unit and the receiver unit to form the wireless access interface providing a plurality of communications resource elements across a first frequency bandwidth which are divided in time into a plurality of frames and forms one of a plurality of cells of the mobile communications network, each cell being allocated a cell identifier by the mobile communications network, wherein the controller in combination with the transmitter unit are configured to transmit in one or more of the frames a synchronisation sequence, which is one of a set of possible synchronisation sequences, each of the synchronisation sequences from the set providing an indication of one of the cell identifiers, wherein a relative temporal location of the synchronisation sequence within the frame provides the communications devices with an indication of the cell identifier of the cell which can be combined with detecting the synchronisation sequence to improve the estimate of the cell identifier for the cell.
