摘要： A radio access network (RAN) may transmit on a plurality of channels, each channel made up of a plurality of subcarriers. Each subcarrier defines a sequence of frames, each frame respectively defining a sequence of time slots. The RAN may transmit symbols in each time slot at at least a nominal power level on each of the subcarriers. The RAN may also determine a subcarrier that is likely to cause adjacent carrier interference between a first wireless device and a second wireless device. The RAN may also transmit null symbols in a first time slot of an initial frame on the determined subcarrier with a power level less than the nominal power level. Additionally the RAN may transmit subsequent symbols with the respective power level of each of the subsequent symbols is successively increased for each subsequent timeslot, for at least the duration of the initial frame.

摘要： During a first time interval, an access point transmits orthogonal frequency division multiplexing (OFDM) signals using a first cyclic prefix length. The access point receives a plurality of signal reports, such as Channel Quality Indicators (CQIs), from user devices being served by the access point. Based on the signal reports, the access point determines a distribution of signal qualities experienced by the user devices. The access point selects a second cyclic prefix length based, at least in part, on the distribution of signal qualities. The access point transmits OFDM signals using the second cyclic prefix length during a second time interval.

摘要： Methods and systems for adjusting a transmit power of a forward link or reverse link signal make use of variable adjustment parameters. The wireless signal is received to obtain a received signal. An observed signal-to-noise ratio (SNR) and an observed frame error rate (FER) for the received signal are determined. In an outer loop process, an adjustment increment is selected based on how much the observed FER differs from the target FER, and the target SNR is adjusted by the adjustment increment. In an inner loop process, a power adjustment command is selected based on a comparison between the observed SNR and a target SNR. The power adjustment command instructs the transmitter of the wireless signal to either increase or decrease the transmit power of the wireless signal. The power adjustment increment may also depend on the observed FER.

摘要： A method for selecting a wireless coverage sector to serve a mobile station, such as in response to a handoff request that designates a sector-identifier that represents two or more possible sectors. A serving radio access network (RAN) may identify potential sectors in the region and may then select the sector whose azimuth is closest to the geographic bearing of the mobile station from the sector's base station. Further, in the event of a tie between two or more sectors or in other circumstances, the RAN may also take into consideration how close the mobile station is to various base stations, such as selecting the sector to whose base station the mobile station is closest. In a system that uses neighbor lists to govern handoff, the invention can help to facilitate handoff in a scenario where a mobile station requests handoff to a sector not listed in the mobile station's neighbor list.

摘要： In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign resources, such as transmit power or frequencies, to wireless coverage areas serving particular altitude ranges in a proportion that is commensurate with the number of WCDs being served by these particular altitude ranges. As a result, RAN and WCD performance may improve.

摘要： A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

摘要： A method and system is disclosed for control of discontinuous transmission based on vocoder and voice activity. An access terminal (AT) may engage in a communication session via an encoder-decoder in a network device in a wireless network. During silence intervals of the communication session, when the AT has no data to transmit, the AT may transmit periodic silence frames at a silence-frame rate to the encoder-decoder. The silence frames may contain parameters for generation of audio noise by the network device. Upon determining that the encoder-decoder has ceased transmitting data to the AT in response to a prolonged absence of transmissions from the AT, the AT may increase the silence-frame rate so as to reduce the duration of the absence of transmissions from the AT, and correspondingly cause the encoder-decoder to begin transmitting audio data to the AT.
摘要翻译：公开了一种基于声码器和语音活动来控制不连续传输的方法和系统。接入终端（AT）可以经由无线网络中的网络设备中的编码器 - 解码器进行通信会话。在通信会话的静默间隔期间，当AT没有要发送的数据时，AT可以以静默帧速率向编码器 - 解码器发送周期性的静默帧。静音帧可以包含用于由网络设备产生音频噪声的参数。在确定编码器 - 解码器已经停止向AT发送数据以响应于来自AT的延迟的传输的情况下，AT可以增加静默帧速率，以便减少不存在来自AT的传输的持续时间，并相应地使编码器 - 解码器开始向AT发送音频数据。

In one embodiment, the PCC transmission scheme may involve an access network engaging in a respective communication session with each of a plurality of access terminals on a given wireless link and sending a respective series of PCCs directed to each of the plurality of access terminals on the given wireless link.

In turn, the access network may send the respective series of PCCs directed to each of the set of access terminals at the adjusted transmission rate.
