    摘要: What is disclosed is a method of operating a wireless communication device. The method includes entering an active state in a first wireless communication mode that requires tuning to a first frequency spectrum, and in response, setting a timer for monitoring a second wireless communication mode. If the timer expires during the active state in the first wireless communication mode, then the method includes tuning away from the first frequency spectrum to a second frequency spectrum for the second wireless communication mode and monitoring information for the second wireless communication mode. If the wireless communication device transitions from the active state to an idle state in the first wireless communication mode before the timer expires, then the method includes tuning away from the first frequency spectrum to the second frequency spectrum for the second wireless communication mode and monitoring the information for the second wireless communication mode.

    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 and system is disclosed for enhanced Simultaneous Hybrid Dual Receive operation. A hybrid access terminal engaged in an IS-856 data communication in a hybrid IS-2000/IS-856 wireless communication system will use its high-gain antenna to conduct IS-2000 tuneaway scans when the access terminal determines that the IS-2000 signal received from its serving base station is below a level that can be reliably detected by its low-gain antenna. At the same time, the access terminal will continue to use its low-gain antenna to engage in the ongoing IS-856 communication, thereby avoiding interruption of the IS-856 communication by IS-2000 tuneaway scans, even when RF conditions are sub-optimal. The access terminal may apply a DRC offset to its DRC request when using just its low-gain antenna for IS-856 communications.

    摘要: What is disclosed is a method of operating a wireless access node which exchanges overhead information with user devices in a series of repeating overhead time cycles each comprising a multi-user message and single-user messages. The method includes transmitting the multi-user messages for receipt and use by all of the user devices and transmitting the single-user messages for receipt and use by individual ones of the user devices. The method includes, in response to the single-user messages, receiving acknowledge messages comprising RF condition indicators for the single-user messages. The method includes, if any of the RF condition indicators are below a performance threshold, then suspending further transmission of the multi-user messages in the series of repeating overhead time cycles, and if none of the RF condition indicators are below the performance threshold, then continuing further transmission of the multi-user messages in the series of repeating overhead time cycles.

    摘要: Systems and methods for dynamically adjusting a metric that influences power management of an access terminal are provided. Initially, an access node is configured to distribute reverse-activity bits (RAB's) to the access terminal, which conveys data, at a particular rate, to the access node. Adjusting the dynamic metric involves establishing a number of slots allocated for a filtered reverse-activity bit (FRAB) window and a hybrid reverse-activity bit (HRAB) window, wherein each of the slots are allocated to accept a RAB. The RAB's accepted to the slots of the FRAB window and the HRAB window are recursively averaged to derive a FRAB parameter and an HRAB parameter, respectively. The dynamic metric is adjusted by incorporating either the FRAB parameter or an HRAB parameter therein based on whether ramping conditions are satisfied. The rate of data conveyed from the access terminal is controlled based on the adjusted dynamic metric.

    摘要: What is disclosed is a method of operating a wireless access control system. The method includes monitoring a first wireless access node to determine when the first wireless access node experiences wireless access congestion, where the first wireless access node broadcasts a first paging zone identifier for receipt by wireless communication devices receiving wireless access from the first wireless access node. The method also includes, in response to the wireless access congestion at the first wireless access node, instructing a second wireless access node which broadcasts a second paging zone identifier to toggle between broadcasting the first paging zone identifier and broadcasting the second paging zone identifier at a first duty cycle.

    摘要: A method and system is disclosed for optimizing handoff of access terminals. In particular, when (i) a given access terminal must switch from a first channel band in a first coverage area to a second channel band in order to hand off to a second coverage area, and (ii) there are no available identifiers to assign to the given access terminal to facilitate making the switch from the first channel band to the second channel band in the first coverage area prior to handing off to the second coverage area, an appropriate identifier is advantageously reassigned from another access terminal to the given access terminal. With the reassigned identifier, the given access terminal may then switch to the second channel band in the first coverage area prior to handing off to the second coverage area.
