摘要： A method and apparatus is provided, where a respective reference signal associated with each of one or more downlink transmit antenna ports in a wireless communication network is received. A value is determined for each of one or more measurable characteristics relative to each of the received reference signals. One or more parameters are received, the parameters including one or more adjustments, where each adjustment is specific to one of the downlink transmit antenna ports and include adjustments in the form of one or more respective offset values to be applied to at least some of the one or more determined values of the measurable characteristics of the received reference signals. At least one downlink transmit antenna port is then to function as a serving downlink transmit antenna port for the user equipment, based upon a comparison of the resulting values of the measurable characteristics of the received reference signals after the received one or more adjustments have been applied to the corresponding determined values.

摘要： In a non-terrestrial network, the delay in reception time may prevent reception of a random access preamble. A combination of increasing transmit power and changing the timing with which the random access preamble is transmitted may enable reception of the random access preamble. One or more criteria may be used to determine whether the timing advance value with which the random access preamble is transmitted should be changed before retransmission is attempted.

摘要： The present invention relates to an apparatus and method for controlling uplink transmission power in a multiple element carrier wave system. The method for controlling uplink transmission power by a terminal in a multiple element carrier wave system includes the steps of: generating an uplink signal to be transmitted in a first serving cell; receiving, from a base station, random access start information for commanding the start of a random access procedure for a second serving cell; calculating the estimated surplus power from first transmission power scheduled for an uplink signal transmission, and second transmission power scheduled for a transmission of a PRACH to which a random access preamble is mapped; and when the estimated surplus power is smaller than a threshold power, adjusting the first transmission power or the second transmission power on the basis of power allocation priority.

摘要： Techniques are described for interference reductions using, e.g., a Received Signal Strength Indicator (RSSI) or packet error rate threshold. User Equipment that implements these techniques may reduce interference among personal area network enabled devices, for example, with the added benefit of reducing power consumption by reduced radio frequency transmissions. By reducing interference, the performance of personal area network devices may be improved.
