The present disclosure relates to the field of communication systems, and more particularly, to an apparatus and a method of wireless communication, which can provide a good communication performance and/or high reliability.
In an unlicensed band, an unlicensed spectrum is a shared spectrum. Communication equipment in different communication systems can use the unlicensed spectrum as long as the unlicensed meets regulatory requirements set by countries or regions on a spectrum. There is no need to apply for a proprietary spectrum authorization from a government.
In order to allow various communication systems that use the unlicensed spectrum for wireless communication to coexist friendly in the spectrum, some countries or regions specify regulatory requirements that must be met to use the unlicensed spectrum. For example, a communication device follows a listen before talk (LBT) or channel access procedure, that is, the communication device needs to perform a channel sensing before transmitting a signal on a channel. When an LBT outcome illustrates that the channel is idle, the communication device can perform signal transmission; otherwise, the communication device cannot perform signal transmission. In order to ensure fairness, once a communication device successfully occupies the channel, a transmission duration cannot exceed a maximum channel occupancy time (MCOT). LBT mechanism is also called a channel access procedure. In new radio (NR) Release 16, there are different types of channel access procedures, e.g., type 1, type 2A, type 2B and type 2C channel access procedures as described in TS 37.213.
In some regions, the channel access is not mandatory, thus a gNB may control whether or not the channel access procedure shall be applied according to the interference environment at gNB or at UE side.

Further, towards higher carrier frequency above 52.6 GHz, due to the severe pass loss, the classical omni-directional transmission will suffer significant coverage limitation. A straightforward solution is to use beam-formed transmission, so that transmission energy can be more focused on the destination, resulting in an increased receive SNR. Similarly, for unlicensed band above 52.6 GHz, e.g. 60 GHz band, beamformed transmission will be used. On the other hand, channel access procedure (or LBT) is still suggested by the regulation. In this case, the legacy channel access procedure may not be suitable for higher frequency due to the fact that the legacy channel access mechanism does not consider beam-forming feature. In some embodiments of this disclosure, some examples present a new design for channel access mechanism over higher frequency, in which beam-forming technique is considered.
