The present invention is related to a statistical multiplexing method and apparatus using a multi-dimensional orthogonal resource hopping multiplexing method in a wired / wireless communication systems where a plurality of communication channels, which are synchronized through a single medium, coexist. The present invention, in order to implement a generalized statistical multiplexing communication system using a multi-dimensional orthogonal resource hopping multiplexing method, comprises a multi-dimensional hopping pattern generator which is located in the primary communication station, a data symbol modulator that modulates data symbols based on the corresponding orthogonal resource hopping pattern generated by said multi-dimensional hopping pattern generator, a collision detector and controller that detects whether a collision occurs or not between the multi-dimensional hopping patterns and compares the consistency of the data symbols toward the secondary communication stations between said collision interval, a transmission power controller that controls the transmission power of the remaining parts excluding the parts where the multi-dimensional hopping patterns collide and the transmission is stopped due to transmitting data symbol inconsistency and compensates for the loss in the average reception energy due to a transmission stoppage.

A method for minimizing the loss of data and ensuring that large delays do not occur during reconfigurations of an uplink transmission time interval (TTI) length of a WCDMA High Speed Packet Uplink Access (HSUPA) air interface, wherein the reconfiguration of an uplink TTI length is delayed until all pending retransmissions are successfully transmitted or until the maximum number of transmissions is reached. The transmission of new packets during this time period is prevented. However, pending retransmissions are allowed to occur. After the UE has received an ACK / NACK for each HARQ process, or until the specific maximum number of re-transmissions is reached, the UE starts transmitting with a new uplink TTI length.

The invention relates to an emitter of a through drill bit dipole acoustic logging device and the logging device. The emitter comprises a base plate and 2n piezoelectric ceramic plates. Each piezoelectric ceramic plate is composed of 2n piezoelectric ceramic units. The two ends of the base plate are provided with through holes. The base plate is fixed to the through drill bit dipole acoustic logging device through the through holes by means of fixing pieces. During work, the piezoelectric ceramic plates on one side of the base plate extend, the piezoelectric ceramic plates on the other side of the base plate shorten, and the base plate is pushed to form bending vibration to radiate thrust towards a medium so as to generate acoustic waves. The sectional type dipole emitter has the characteristic of low-frequency and high-power emission and is suitable for a transducer in through drill bit small-diameter acoustic logging and more suitable for transverse wave measurement of soft stratums and even super-soft stratums.
