    Abstract: A first node transmits a first signal; receives a second signal; and transmits a third signal on a target time-frequency resource block; the second signal is used to indicate a first time-frequency resource block, the first time-frequency resource block is used to determine a target time-frequency resource set, and the first time-frequency resource block is one of the multiple time-frequency resource blocks comprised in the target time-frequency resource set; the target time-frequency resource block is one of the multiple time-frequency resource blocks comprised in the target time-frequency resource set, and whether the third signal carries a first-type information block is used to determine the target time-frequency resource block out of the target time-frequency resource set; the first-type information block comprises control-plane information. The present application transmits a Message 3 through additional time-frequency resources to reduce the conflict of random access to mainstream services.

    Abstract: The present disclosure method and device in node used for wireless communication. A first node receives first information, the first information being used for indicating a first time-unit format; determines second information; and determines a first resource pool; herein, a first time window comprises Q first-type time-domain-resource blocks, the Q being a positive integer greater than 1; a first symbol is one of the positive integer number of multicarrier symbol(s) comprised in any of the Q first-type time-domain-resource blocks; the first time-unit format is used for indicating whether the first symbol is a first-type symbol; the second information is used for indicating a positive integer number of first-type time-domain-resource block(s) out of a first time-domain-resource-block subset. A flexible slot format has been taken into account in the process of V2X resource pool configuration in the present disclosure, thus ensuring that the resource pool can effectively meet traffic requirements.

    Abstract: Embodiments of the present invention disclose triggering methods and apparatuses of aperiodic channel state information CSI and an aperiodic sounding reference signal SRS for a carrier aggregation system. The method comprises: (1) pre-assigning a corresponding relationship between bits of the CSI request field in an uplink grant and multiple downlink component carriers DL CCs of user equipment, wherein the number of bits of the CSI request field is greater than 1 and less than the maximum allowed number of DL CCs in the system; (2) determining the DL CC for which aperiodic CSI reporting is to be triggered; and (3) mapping the CSI request field in the uplink grant according to the pre-assigned corresponding relationship to mark the value of the bit corresponding to the determined DL CC as “trigger”.

    Abstract: The present invention relates to a method of configuring an aperiodic sounding reference signal. In an embodiment of the method of configuring an aperiodic sounding reference signal, the parameters of the aperiodic sounding reference signal are categorized into two parts. The first part of parameters can be configured by radio resource control signaling, and the second part can be configured dynamically via the indication in downlink control information format 4. The second part of the parameters includes at most three of the following parameter set: cyclic shift, the number of antenna ports, carrier aggregation, sounding reference signal bandwidth, frequency-domain position, sounding reference signal hopping bandwidth, multi-shot sounding reference signal duration, and transmission comb. The first part of the parameters includes sounding reference signal configuration index and the remaining part of the parameter set. With the method of the present invention, the second part of the parameters of an aperiodic sounding reference signal can be flexibly configured to adapt to various application scenarios.
