    Abstract: Embodiments of the present disclosure provide a V2X communication method and apparatus. The method is applicable for a V2X node and includes: detecting a downlink control channel whose CRC code is scrambled by a V-RNTI relevant to the V2X node; and receiving V2X data information on a corresponding downlink data channel according to an indication of the detected downlink control channel. In the present disclosure, the receiving V2X node is able to receive V2X data information selectively, which avoids useless data receiving and data processing operations of the receiving V2X node, reduces the number of downlink control channels and downlink data channels to be detected and processed by the receiving V2X node.

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a power allocating method. A User Equipment (UE) receives power control indication information from a control node, obtains a power control mode, and/or, uplink transmission power configuration information. The UE allocates power for each uplink carrier, based on the power control mode, and/or, the uplink transmission power configuration information. By applying the present disclosure, power waste generated in the following scene may be reduced. A scheduled uplink signal cannot be transmitted in a corresponding carrier due to a busy channel. Subsequently, uplink scheduling efficiency of the UE may be improved, and the whole network efficiency may also be enhanced.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present disclosure provides method for transmitting signals on an Unlicensed Frequency Band (UFB), comprising: performing, by a transmitting node, a first type of Listen Before Talk (LBT) on a direction i; transmitting, by the transmitting node, signals on a direction j after passing the first type of LBT, wherein the direction i is omnidirectional, or one or multiple beam directions corresponding to the direction j. The technical scheme of the present disclosure may be applied to high-frequency-band signal transmission and LBT and avoid interference with other nodes on the UFB.

    Abstract: The present disclosure provides a hybrid duplex communication method and apparatus. Configuration information is obtained. The configuration information includes locations of special sub-frames on the first carrier, and a transmission direction of each sub-frame on the second carrier. Sounding Reference Symbol (SRS) is sent on a special sub-frame. when all sub-frames on the second carrier are UL sub-frames, the UE may communicate with the BS on the first carrier and the second carrier according to the FDD mode; when the second carrier is used for UL and DL transmission in time division multiplexing mode, the UE may communicate with the BS on DL resources of the first carrier and UL resources of the second carrier according to the FDD mode, and/or, the UE may communicate with the BS on DL resources of the second carrier and UL resources of the second carrier according to the TDD mode.

    Abstract: An apparatus and method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information are provided. The apparatus and method include user equipment (UE) that first receives a downlink grant (DL-GRANT) which schedules downlink HARQ transmission in a time-frequency bundling window corresponding to an uplink subframe used for feeding back HARQ-ACK, obtains a DL downlink assignment index (DL DAI) in the DL-GRANT, and determines a mapping value of each DL DAI. Then, according to the mapping value of the corresponding DL DAI, the HARQ-ACK bit of each HARQ feedback unit is mapped to a corresponding bit of a feedback bit sequence. According to the method and apparatus provided by the present disclosure, useless HARQ-ACK bits may be effectively removed, and efficiency for feeding back HARQ-ACK may be increased. As such, a downlink peak rate of a UE is ensured.

    Abstract: A first device senses scheduling assignment (SA) and received power of a second device, and a total received energy of each subband. The first device determines a reference value of received power of the second device and a reference value of total received energy, based on a sensing result of the second device. The first device selects a resource, based on the reference value of received power and reference value of total received energy, the first device transmits data. By adopting the method of the present disclosure, decoding performance of SA is improved, and accuracy for measuring received power of the SA is also enhanced. Subsequently, on the basis of SA and received power, performances for selecting/re-selecting channel resources are improved.
