摘要： Techniques to transmit pilot on a CDMA segment on the reverse link in a wireless communication system are described. A terminal generates a scrambling sequence based on its pilot information. The pilot information may be used for the entire duration of a call by the terminal and for all sectors with which the terminal communicates during the call. The terminal generates pilot symbols based on the scrambling sequence, maps the pilot symbols to the CDMA segment, generates OFDM symbols with the mapped pilot symbols, and sends the OFDM symbols to one or more sectors. A base station processes received OFDM symbols to obtain received symbols for the CDMA segment. The base station generates the scrambling sequence based on the pilot information for the terminal and processes the received symbols with the scrambling sequence to obtain at least one parameter (e.g., received signal strength) for the terminal.

摘要： Techniques for selecting serving sectors and performing handoff for a terminal on the forward and reverse links are described. The terminal may obtain pilot measurements for pilots transmitted on the forward link and may update an active set based on the pilot measurements. The terminal may send a transmission (e.g., for pilot, signaling, etc.) on the reverse link and may receive channel quality information indicative of reverse link channel quality for the terminal at multiple sectors in the active set. The transmission may include pilot, and the channel quality information from each sector may include a pilot carrier-over-thermal ratio (pCoT) determined by that sector based on the pilot. The terminal may select a serving sector based on the channel quality information, interference information, and/or other information and may send a request for handoff (e.g., via a signaling message an/or an access probe) to the selected serving sector.

摘要： Techniques for controlling transmit power of a terminal are described. The terminal may send a first transmission (e.g., for pilot or signaling) on the reverse link, receive feedback (e.g., a power control command or an erasure indicator) for the first transmission, and adjust a reference power level based on the feedback. The terminal may also receive interference information and possibly other parameters such as a pilot quality indicator (PQI), an offset factor, and a boost factor from a sector. The terminal may determine transmit power for a second transmission to the sector based on the interference information, the reference power level, and/or the other parameters. The terminal may receive the feedback from one sector and may send the second transmission with CDMA or OFDMA to the same sector or a different sector.

摘要： Systems and methodologies are described that facilitate grouping pilot identifies to indicate type and/or classification information regarding one or more access points. The access points can select or be assigned pilot identifiers from the group indicating a type or classification related to the access points. Thus, identifiers can be grouped into macrocell and/or femtocell groups or ranges such that an access point can indicate, and mobile devices can efficiently determine, whether the access point provides macrocell or femtocell coverage based on a range from which its pilot identifier is selected or assigned. In addition, the pilot identifiers can be utilized to indicate restricted association information regarding the access points.

摘要： Softer handoff groups are provided utilizing fractional frequency reuse set, which can be managed by a single master sector that is part of the group. The group can based on handoff rules that can include a group indication by an access point or a group request by an access terminal. A terminal is provided functionality to select a softer handoff group, which can be indicated by an active set update. An access point can discontinue serving terminals by groups by reducing an active set size to one. Diversity can be provided such that if a transmission from one sector fades, the other sector can provide the transmission, mitigating loss of data. Thus, robustness against inadequate channel conditions can be obtained.

摘要： Systems and methodologies are described that provide techniques for managing persistent resource assignments in a wireless communication system. An access point can generate a bitmap by mapping access terminals having persistent assignments for traffic channels to a series of bitmap bits that provide keep-alive indications for the access terminals. The bitmap can then be provided as a common keep-alive message in a broadcast or multicast transmission to the access terminals. The keep-alive message can further include CRC bits for error prevention. An access terminal, upon receiving the keep-alive message, can then determine whether a bitmap bit in the keep-alive message corresponding to the access terminal conveys a keep-alive indication for the terminal and utilize its persistently assigned traffic channels accordingly.
