Abstract: The present invention discloses an uplink data transmission method and device configured to shorten RTT in a transmission condition having a short time slot, thus reducing a user-plane latency and improving the system performance. An embodiment of the present invention provides an uplink data transmission method. The method comprises: determining, by the network side, a time slot size for data transmission, and sending, according to the time slot size, uplink scheduling signaling to a user equipment (UE); and receiving, by the network side and according to a predetermined scheduled timing, uplink data sent by the UE, wherein the time slot is a time unit having a duration smaller than 1 ms, and the predetermined scheduled timing is that when the network side employs a time slot n to send the uplink scheduling signaling, the network side receives the uplink data sent by the UE in a time slot (n+1), with l∈L, n and l both being integers greater than or equal to zero, and L denoting the set of selectable values of l.

Abstract: Disclosed are a relay terminal reselection method and device. A control node performs relay terminal reselection judgement for a source terminal according to a reselection triggering condition of a relay terminal, and if deciding to perform relay terminal reselection, the control node determines a candidate relay terminal list for the source terminal and determines a destination a destination relay terminal for the source terminal from the candidate relay terminal list according to auxiliary information, wherein the control node is the source terminal or a source relay terminal, such that when in the moving process of the source terminal, a target node and the source relay terminal, the source relay terminal is no longer suitable to be used as a relay terminal, the source terminal or the source relay terminal can reselect a relay terminal for the source terminal.

Abstract: Disclosed are a determination method and apparatus for pre-set set parameters of an audio equalizer (AEQ), which are used for reducing an overflow phenomenon of fixed-point arithmetic output of all levels of second-order infinite impulse response (IIR) filters while frequency response amplitude curves of an AEQ remain unchanged, and reducing non-linear distortion, thus reducing total harmonic distortion (THD) of an AEQ system. The determination method for pre-set set parameters of an AEQ comprises: determining a first frequency point set by utilizing frequency response amplitude curves of an AEQ; adjusting the frequency response of frequency response amplitude curves of all levels of second-order IIR filters at a frequency point in the first frequency point set, so that the frequency response of the frequency response amplitude curves of all the levels of second-order IIR filters at the frequency point in the first frequency point set satisfies a pre-set condition; and adjusting a first parameter set and a second parameter set according to the adjusting variable of the frequency response amplitude curves of all the levels of second-order IIR filters, and determining the adjusted first parameter set and the adjusted second parameter set as pre-set set parameters of the AEQ.

Abstract: Disclosed are a D2D communication method and device. The method comprises: sending a. preamble on a sub-channel set of a competition region, and monitoring the preamble on the sub-channel set of the competition region; and if the preamble is not monitored on the sub-channel set of the competition region, sending data on a sub-channel set of a data region corresponding to the sub-channel set of the competition region, different sub-channel sets of the competition region corresponding to different sub-channel sets of the data region. The technical solution provided in the embodiments of the present invention can effectively avoid the resource conflict of a D2D UE. In addition, since a preamble occupies fewer resources, competing for sub-channel resources of a data region by sending a preamble could effectively reduce the overhead of resource competition.
