Abstract: A message transmitting/receiving apparatus and method and a communication system. The message transmitting method includes: determining a message type of a message to be transmitted to one or more user equipments; scrambling control information of the message by using an identity to which the message type corresponds; wherein, different identities correspond to different message types; and transmitting data information of the message and the scrambled control information to the one or more user equipments. Hence, the user equipment may not proceed with processing a message that is not preferred, thereby lowering power consumption of the user equipment.

Abstract: A transmission method and apparatus for a demodulation reference signal and a communications system. The transmission method includes: transmitting a DMRS by a transmitting device to a receiving device; the number of symbols in each subframe for transmitting the DMRS is configured as 1 or more than 2. Hence, more than 2 symbols for transmitting the DMRS are configured in each subframe, which may increase a transmission density of DMRS, and satisfy a demand of a new traffic, such as V2X, for a moving speed; or a single symbol for transmitting the DMRS is configured in each subframe, which may satisfy a demand of a low-speed mobile traffic, such as the cellular IOT, and lower overhead.

Abstract: Embodiments of this disclosure provide a method and apparatus for performing multiuser superposition transmission over repetition-based transmission and a system. In this embodiment, the method includes: an eNB transmits repetition configuration information or repetition configuration information and modulation scheme information of second UE utilizing a repetition-based transmission technique to first UE paired with the second UE for performing MUST transmission, so that the first UE detects data of the second UE and performs interference cancellation according to the repetition configuration information or the repetition configuration information and the modulation scheme information of the second UE, so as to obtain data of the first UE. With the embodiments of this disclosure, unnecessary signaling overhead and repeated detection may be avoided, thereby improving performance and efficiency of MUST transmission.

Abstract: This disclosure provides a group communication apparatus and method and a communication system. The group communication method includes: scrambling data information of a message by using corresponding scrambling information according to a message type and/or a message transmission range; wherein, different message types and/or message transmission ranges correspond to different scrambling information. Therefore, internal members or peripheral devices of a group may selectively receive messages of different types or different target ranges. Hence, not only messages may be ensured to be accurately received by corresponding receivers, but also security of internal message may be improved.

Abstract: An information transmission apparatus and method and communication system. The information transmission method includes: receiving transmission information containing data, which is transmitted by a transmitting device in a grant-free manner; identification information of the transmitting device is explicitly or implicitly carried in the transmission information; demodulating and checking the transmission information, and determining whether the identification information of the transmitting device and the data contained in the transmission information are correctly obtained; and feeding control information containing ACK/NACK back to the transmitting device, by using the identification information of the transmitting device or using sequence information of a DM-RS that is used for demodulating the transmission information.

Abstract: A resource allocation method, apparatus and communication system. A base station allocates a priority for each resource unit in the resource pool, and notifies information on the priorities to a user equipment in its coverage, such that the user equipment may select a corresponding resource unit for its message to be transmitted (a V2X packet) according to the configuration information on the priorities of the resource units from the base station. Hence, the probability of resource collision can be lowered, and the latency can be ensured to be low.

Abstract: An apparatus and method for paging a UE and a communications system. The method includes: calculating a first-grade paging group index based on an inherent identity of the UE, or based on an inherent identity of the UE and a network configuration parameter; calculating a second-grade paging group index based on a network identity allocated by an MME; receiving indication information for indicating paging group indices transmitted by a base station; determining whether the information contained in the indication information is consistent with the first-grade paging group index and the second-grade paging group index; and decoding a downlink data channel to determine whether the UE is paged when it is consistent. Hence, different paging groups may have identical or approximate numbers of UEs, which may reduce a probability of “false paging” of the overall cell.

Abstract: A paging apparatus and method and a communication system. The paging method includes: determining a paging occasion of a user equipment based on one or more beam identities in a paging set; and transmitting a beam-based paging message to the UE when the paging occasion arrives. Hence, when the paging occasion of the user equipment arrives, beams of the base station may be directed to the user equipment, and a paging message may be efficiently and reliably transmitted.
