A cell search and synchronization method in a wireless communication system providing at least one cell having a frequency span in the frequency domain, the method includes: defining, for a said cell, a plurality of resources within the frequency span and within a defined time frame for transmitting a synchronization signal wherein a resource is characterised by a location in the frequency domain and a location in the time domain; and transmitting the synchronization signal in more than one of the plurality of resources.

Synchronization signals in 5G

A 5G wireless communication system to transmit a beam ID or part of a beam ID by joint design of a secondary synchronization sequence (SSS) and Physical Broadcast Channel (PBCH). In 5G during the initial access procedure a terminal will try to obtain fundamental system information/identifiers which are required for future signal transmission/reception activities. Due to the extensive usage of beamforming techniques in 5G, besides identifying a cell ID and obtaining time/frequency synchronization, the terminal may identify a beam ID during the initial access procedure. Therefore, a beam ID is transmitted as part of synchronization signals (SS) broadcast by a gNB, more particularly as part of SSS or as part of PBCH. The synchronization signals may be transmitted as a set of SS blocks, each having an index, which may be a time index, for facilitating identification.

Synchronization and broadcast signal design for 5G

In LTE a measurement configuration message, which instructs a terminal () on when to transmit a measurement report, is per frequency carrier dependent. A measurement object configuration for 5G/NR wireless communication is provided which is independent of carrier frequency, allowing multiple measurement objects to be configured for one particular carrier frequency. Each measurement object can be defined over a particular time duration (T, T, T), frequency range, time/frequency grid, beam, and/or a particular frequency carrier (Layer 1, Layer 2) in order to satisfy various requirements on RRM measurement of NR. Thus, for a particular terminal () and a particular carrier frequency, a base station () can define multiple measurement objects over different time/frequency grids.

The present invention relates to space-time or space-frequency coding in cellular systems. The same data is transmitted from different antennas with different coverage areas, corresponding to different cells. The different data streams have different parts of the space-time block codes applied. A mobile terminal can combine the different parts of the space-time block codes in different received signals. This provides better performance than the known techniques for single frequency networks. The invention can also be applied to antennas with different coverage areas from the same site, and different beams formed with antenna arrays.

Space-time/space-frequency coding for multi-site and multi-beam transmission

An apparatus and a method provide for uplink interference coordination in a radio communication system, such as a cellular communication system. Measurements are made at mobile stations associated with uplink-channel interference conditions. Reports are made to the network when a mobile station experiences interference conditions beyond a measurement threshold. If greater than a group-threshold number of mobile stations experience high levels of uplink-channel interference, communication resources are reallocated in compensation for the high interference conditions.
