Abstract: Embodiments of the present disclosure relate to a method and apparatus of transmitting uplink (UL) information and a method and apparatus of receiving UL information. In one embodiment of the present disclosure, the method of transmitting UL information comprises transmitting a reference signal using a first sequence; and transmitting UL control information using a second sequence; wherein a reference signal and the UL control information are staggered-multiplexed in frequency domain. With embodiments of the present disclosure, the uplink information can be transmitted in reduced uplink symbols so as to adapt for a proposed subframe structure with reduced uplink symbols and thus, the transmission latency can be reduced greatly.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses for transmitting and receiving reference signals. In transmitting reference signals, reference signals are transmitted using a first group of configuration resources within a first transmission resource group; and the reference signals are transmitted using a second group of configuration resources within a second transmission resource group. The first group of configuration resources are determined based on allocated resource configurations for the reference signals and the second group of configuration resources are a subset of the first group of configuration resources.

Abstract: Embodiments of the present invention provide method and devices for signaling transmission in unlicensed band. The method comprising determining a signal transmission pattern, which defines time and frequency resources for transmitting at least one signal in a first frequency band; signaling, via a second frequency band, the signal transmission pattern to a first device; and transmitting the at least one signal via the first frequency band, to the first device, according to the signal transmission pattern; wherein a transmission of one of the at least one signal is skipped if time and frequency resource for the transmission defined by the signal transmission pattern is detected as busy. Corresponding methods and devices for receiving a signal which is transmitted using above method are also disclosed.

Abstract: Embodiments of the present disclosure relate to a method and apparatus of transmitting a reference signal and a method and apparatus of receiving a reference signal. In one embodiment of the present disclosure, the method of transmitting a reference comprises receiving a reference signal configuration indication, wherein reference signal resources are divided into at least two reference signal groups, and the reference signal configuration indication indicates a reference signal configuration including a reference signal group configuration; and transmitting the reference signal using a reference signal sequence in a reference signal group as indicated by the reference signal group configuration, wherein the reference signal sequence can be multiplexed with another layer or another user in different reference signal groups. With embodiments of the present disclosure, reference signals for different layers or users can be multiplexed in different reference signal groups and thus, more mu-users with unequal allocated bandwidths can be supported without significant channel estimation loss and Peak to Average Power Ratio (PAPR) loss.
