Abstract: Systems and methodologies are described that facilitate optimizing parameters for random access in a wireless communication environment. A network manager can select centrally optimized parameters for random access that mitigate interference among RACH attempts and/or mitigate uplink interference due to RACH in a SON. Moreover, a base station can select locally optimized parameters for random access that mitigate a number of access attempts, mitigate interference among RACH attempts, and/or mitigate uplink interference due to RACH. The centrally optimized parameters can include PRACH configurations, root sequence parameters, ranges for one or more MAC parameters (e.g., initial transmit power, power ramp step, maximum number of preamble transmissions, contention resolution timer,...), and so forth. Further, the locally optimized parameters can include sequence length, one or more MAC parameters (e.g., initial received target power of the random access preamble, power ramp step, contention resolution timer, maximum number of preamble transmissions,...), etc.

Abstract: A method for power control in a wireless communication system. An initial transmission of a data frame in the reverse link is received, and a first energy level of the data frame is measured. An energy deficit in the first energy level is then measured if the first energy level is insufficient to correctly decode the data frame, so that when the data frame is retransmitted with a second energy level equal to a difference between the first energy level and the energy deficit, the data frame can be correctly decoded with combined energy of the first energy level and the second energy level.

Abstract: An acknowledgement method in a wireless communication system. Initially, a reverse supplemental channel (R-SCH) frame is received at a base station. The base station then transmits an acknowledgement (ACK) signal if quality of the received R-SCH frame is indicated as being good. A negative acknowledgement (NAK) signal is transmitted only if the received data frame is indicated as being bad but has enough energy such that, if combined with energy from retransmission of the data frame, it would be sufficient to permit correct decoding of the data frame. If the best base station is known, the acknowledgement method may reverse the transmission of the acknowledgement signals for the best base station so that only NAK signal is sent. A positive acknowledgement is assumed in the absence of an acknowledgement. This is done to minimize the transmit power requirements.

Abstract translation: 无线通信系统中的确认方法。 最初，在基站接收到反向补充信道（R-SCH）帧。 然后，如果接收的R-SCH帧的质量被表示为良好，则基站然后发送确认（ACK）信号。 仅当所接收的数据帧被表示为坏但具有足够的能量使得如果与来自数据帧的重传的能量相结合时才允许数据帧的正确解码就足够了，才发送否定确认（NAK）信号 。 如果最好的基站是已知的，则确认方法可以反转用于最佳基站的确认信号的发送，从而仅发送NAK信号。 在没有确认的情况下假设肯定确认。 这样做是为了最小化发射功率要求。

Abstract: Rather than attaching a preamble to a data traffic subpacket, a preamble channel is transmitted along with a traffic channel. In a system wherein the data traffic subpackets are variably sized, preambles can also be variably sized if a target station can decode variably sized preambles (390a, 390b, 390c). A method and apparatus for decoding variably sized preamble subpackets are presented herein.

Abstract: Rather than attaching a preamble to a data traffic subpacket, a preamble channel is transmitted along with a traffic channel. An ARQ channel is established on the reverse link in response to a received transmission on the preamble channel and the traffic channel. In accordance with the type of ARQ signal received (622, 626, 627, 631), or the lack of receipt thereof (630, 635), a scheduling element in the base station alters an already existing transmission schedule for transmitting old data traffic or new data traffic.

Abstract: Management of uplink resources in a wireless communication is presented. In one embodiment, management of uplink resources comprises receiving a multi-bit acknowledge (multi-bit A/N) that is available for uplink transmission and receiving other information that is available for uplink transmission along with the multi-bit A/N. Next, it is determined whether a condition has been met. If the condition has been met, an uplink message is created comprising the multi-bit A/N but dropping the other information. If the condition has not been met, an uplink message is created which jointly codes the multi-bit A/N and the other information. The uplink message is then transmitted to a receiver.
