    摘要： In a method for efficient retransmission of data, symbol accumulation is used to retransmit a packet received in error at a lower energy-per-bit level concurrently in the same frame with a new packet. The destination device receives the data transmission and retransmission, demodulates the signal, and separates the received data into the new and retransmitted packet. The destination device then accumulates the energy of the retransmitted packet with the energy already accumulated for the packet received in error and decodes the accumulated packet. The accumulation of the additional energy provided by the subsequent retransmissions improves the probability of a correct decoding. The throughput rate can be improved since the packet received in error is retransmitted concurrently with the transmission of the new data packet. The capacity is maximized since the retransmission of the packet received in error is at a lower energy level than that of the new packet. The method includes puncturing the code symbols of a data packet for transmission in accordance with a first puncturing pattern. If decoding of the punctured transmitted packet of data is unsuccessful, a negative acknowledgement is received at the source device and the code symbols of the data packet are then punctured in accordance with a second pattern for transmission in response to the receipt of the negative acknowledgement.

    摘要翻译： 在用于有效重发数据的方法中，使用符号累加来以与新分组相同的帧同时以较低的每比特能级重传错误接收的分组。 目的设备接收数据传输和重传，对信号进行解调，并将接收到的数据分离成新的和重发的分组。 然后目的地设备以错误地接收到的分组已经累积的能量累积重传的分组的能量，并对累积的分组进行解码。 由后续重传提供的附加能量的累积提高了正确解码的概率。 可以提高吞吐率，因为与新数据分组的传输同时重发错误接收的分组。 容量被最大化，因为错误接收的分组的重传处于比新分组更低的能级。 该方法包括根据第一穿孔模式对用于传输的数据分组的代码符号进行删截。 如果对穿孔的所发送的数据分组的解码不成功，则在源设备处接收到否定的确认，并且响应于接收到否定确认，根据用于发送的第二模式，对数据分组的代码符号进行删截。

    摘要： A method and apparatus for coordinating the time at which a mobile station (5) performs searches for alternative systems to which a hard handoff will occur. In one system which includes the present invention, the mobile station (5) receives a command which instructs the mobile station (5) as to when to tune to alternative frequencies in order to search for indications of the presence of an alternative system. In another system which includes the present invention, predetermined times are defined with respect to a reference point in time that is common to both a origination base station (10) and a mobile station (5). The mobile station (5) tunes to alternative frequencies to perform searches only during these predetermined times. In addition, the mobile station (5) coordinates the transmission of reports which indicate the results of searches for alternative systems such that these reports are only transmitted from the mobile station (5) when the mobile station (5) is tuned to the origination frequency.

    摘要： A mobile station comprising a receiver (590) for receiving signals, including parameter data (OFNLM) of an origination system (S1) representing a parameter value (MIN_RX_PWR, MIN_TOT_PILOT) of signals of a different, destination system (S2); a controller (52) coupled to the receiver for controlling the receiver to change between receiving signals of the origination communication system (S1) and receiving signals of the destination communication system (S2); and parameter measuring means (530, 540) for measuring a parameter of received signals of the destination communication system (S2), the parameter measuring means being coupled to the controller (520) to provide measured parameter data thereto. The received parameter data comprises control data (RETURN_IF_FAIL) indicating whether the mobile station should receive again signals of the origination communication system (S1). The controller (520) is arranged to operate by comparing the measured parameter with received parameter values (MIN_RX_PWR, MIN_TOT_PILOT), and controlling the receiver to receive again signals of the origination communication system (S1) based on the comparison of the measured parameter data and the received parameter data values and on the control data (RETURN_IF_FAIL). A corresponding method is also described.
