Abstract: A method and apparatus are provided for transmitting and receiving control information. A method performed by a UE includes receiving, from a base station, DCI or a higher layer signaling; when first priority UCI and second priority UCI are transmitted in a same physical uplink channel, separately encoding the first priority UCI and the second priority UCI, based on a first number of bits of the first priority UCI and a second number of bits of the second priority UCI; and transmitting, based on the DCI or the higher layer signaling, the encoded first priority UCI and the second priority UCI, to the base station, on the same physical uplink channel.

Abstract: The present disclosure provides several methods, user equipment (UEs) and base stations for transmitting uplink signals. After receiving uplink synchronization command information, the UE may transmit an uplink signal on at least one idle unlicensed cell. Besides, the UE may try to transmit the uplink signal on multiple uplink signal resources within an uplink signal transmission window. By using the present disclosure, transmission probability of uplink signals may be improved, and time delay of uplink synchronization may be shortened.

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). A technique for receiving a downlink control channel is provided that includes operations of determining whether a physical downlink shared channel (PDSCH) is received at a time-domain position n; determining, according to a result of the determining, a frequency-domain position of a bandwidth part (BWP) for receiving a physical downlink control channel (PDCCH) at a time-domain position n+1, and receiving the PDCCH at the BWP of the frequency-domain position. The technique determines the frequency-domain position of the BWP for receiving the PDCCH by determining whether it is necessary to receive the PDSCH at the time-domain position preceding the current time-domain position for receiving the PDCCH, greatly reducing or even eliminating the influence of the adjustment time interval for the user equipment (UE) to convert the BWP on the normal data reception of the UE, which ensures the receiving performance and the throughput level of the received data of the UE.
