A method and apparatus for sharing a DL-DPCH in an NB-TDD system. Two time slots at the same position in two subframes forming one radio frame are allocated as a DPCH for two UEs. A Node B arranges data and control information for the UEs in the two time slots and transmits the data and control information to the UEs. The UEs extract the data and control information from the two time slots and acquire the data and control information destined for the individual UEs.

An alternative signaling transmission method includes such steps as determining the least scheduling interval, allocating up and down control channels, dividing up (or down) signaling into several parts, alternatively transmitting them in different time slots, and distinguishing the contents of up (or down) signaling by using a parameter relative to time.

The invention relates to a method for providing an MBMS service in a wireless communications system comprising a mobile network (N) communicating over a radio air interface (Al) with a plurality of UEs (T1 to Tn) desiring to receive the MBMS service in a cell (CA), the method comprising the steps of: using a point to multipoint on a common channel transmission mode with a preset amount of transmission power (106); detecting if there are UEs in the cell (CA) which receive low MBMS service quality with said point to multipoint on a common channel transmission with a preset amount of transmission power set to a value less than the amount of transmission power needed to cover the whole cell area (108); and using ± point to point on dedicated channels transmission mode for such detected UEs receiving low MBMS service quality with said point to multipoint on ± common channel transmission with ± preset amount of transmission power (110).

A method for transmitting information includes by a NodeB, receiving a message for setting up / reconfiguring a shared Enhanced Dedicated Channel (E-DCH) transmission channel from a Radio Network Controller (RNC); and setting up the shared E-DCH transmission channel according to parameters in the message, and exchanging information with the RNC through an established shared E-DCH transmission bearer.

The invention discloses a flying ad-hoc network channel access control method based on traffic prediction, and the method comprises the steps: predicting the arrival traffic of a next time frame by using a neural network according to a historical value through a traffic prediction theory in combination with the autocorrelation of the packet arrival traffic of an unmanned aerial vehicle over time, so as to make a channel allocation scheme; by the neural network, adjusting parameters in the negative gradient direction of the target based on a gradient descent strategy, and stopping iteration until a training error is smaller than or equal to a preset error threshold value; and on the basis of a neural network algorithm, calculating the minimum transmission time required by the unmanned aerial vehicles for transmitting a video packet, so that the bandwidth of the video packet is preferentially guaranteed when the current channel resource cannot meet the service requirements of all the unmanned aerial vehicles. According to the method, the traffic prediction method can be used, the neural network is used to predict the traffic which is about to arrive in the unmanned aerial vehicle networking communication range in the next time frame, and channel resources are allocated to the traffic.
