TIMING SYNCHRONIZATION IN DISCOVERY SIGNALS

摘要

Embodiments described herein relate generally to a device that is to transmit signals using a control channel. The device may be, for example, a user equipment or low-powered radio access node. Before transmitting the signal, the transmitting device may modify symbols associated with the signal. For example, the transmitting device may generate a scrambling sequence and modulate the symbols associated with the signal with the scrambling sequence. In another example, the transmitting device may apply a shifting pattern or hopping pattern to the sequence indices associated with sequences for symbols to be included in the signal. The applied pattern may change one or more sequence indices associated with one or more symbol indices associated with the signal. Other embodiments may be described and claimed.

1. An apparatus to be included in a device, the apparatus comprising:
processing circuitry:
to generate a discovery signal that includes a first symbol associated with a first control channel sequence for discovery of the device by another device for a wireless device-to-device communication; andto modify a sequence index associated with the first control channel sequence by application of a predetermined function to the sequence index, the predetermined function to change an association of the sequence index from a first symbol index to a second symbol index; and communication circuitry, communicatively coupled with the processing circuitry, the communication circuitry to transmit the discovery signal associated with the modified sequence index to improve timing acquisition between the device and the other device.
