摘要： The embodiments of the present invention disclose a backplane and backplane system. The backplane includes at least two service slots with the same function and an exchange slot. Among the pins of different service slots with the same function respectively connected to the exchange slot, at least two pins are arranged to resemble a stepped form. When arranged in this manner, the distribution and orientation of the connection lines connecting the pins of the service slots with the same function to the exchange slot may be adjusted, and wiring density within a single wiring layer may be increased, which therefore enables the connection lines between the service slots and the exchange slot to be staggered from each other in less wiring layers or even one wiring layer, and as a result, decreases the number of the wiring layers to be used, and reduces the costs of the backplane.

摘要： A method for communicating channel state information (CSI) to a base station is presented. The method includes identifying a number of allocated resources for CSI within at least one of a Physical Uplink Control CHannel (PUCCH) payload and a Physical Uplink Shared CHannel (PUSCH) payload. The method includes encoding channel state information (CSI) for activated carriers on a user equipment into the allocated resources for CSI. When a number of activated carriers on the user equipment is less than the number of allocated resources for CSI, the method includes using repetition encoding to duplicate the CSI for at least one of the activated carriers on the user equipment into the allocated resources for CSI.

摘要： A method and apparatus for optimizing target error rates for link adaptation in a communication system. The method includes estimating a data rate associated with transmission of a data stream over a communication link. A required target error rate is then selected from a plurality of pre-defined target error rate values based on whether the estimated data rate is within a range of at least one of a plurality of pre-defined threshold values, where each of the pre-defined target error rate values maps to one of the plurality of pre-defined threshold values. A link adaptation parameter associated with the communication link is then selected or updated to maintain the required target error rate and the data stream is transmitted over the communication link using the selected/updated link adaptation parameter.
