摘要： A method and apparatus for transmitting a SystemInfo block in an Active state in a wireless communication system is described. The SystemInfo block is transmitted every NpBCH0—Period superframe. The SystemInfo block is carried over a primary broadcast channel (pBCH0) physical channel by a control channel medium access control (MAC) protocol. The SystemInfo block is prevented from passing through a signaling transport. The SystemInfo block is transmitted on each carrier if a multi-carrier mode is MultiCarrierOn, where the contents of the SystemInfo block is identical for all carriers except for a CarrierID, a FLReservedInterlaces and a NumFLReservedSubband

摘要： Systems and methodologies are described that facilitate recovering from error due to false detection of completion signals at an access terminal. An access terminal specific request signal can be sent to a target base station to initiate handoff or semi-connected state exit. A completion signal can be transferred in response to the access terminal specific request signal. To mitigate errors stemming from false detection of the completion signal at the access terminal, forward link and reverse link confirmation signals can be transferred to confirm successful handoff or connected state re-entry completion. For example, the access terminal can determine handoff or re-entry to be successful when a forward link confirmation signal is detected prior to expiration of a timer. Moreover, the forward link and reverse link confirmation signals can each include more CRC bits as compared to a number of CRC bits included in the completion signal.

摘要： Techniques for performing carrier switching in a multi-carrier access network are described. A terminal may be assigned to a carrier among multiple carriers having different transmit power levels, e.g., by the access network during system access or handoff. The terminal may receive a switch threshold from the access network. The terminal may periodically measure the received signal strength of the assigned carrier and may compare the received signal strength against the switch threshold. The terminal may refrain from switching to a stronger carrier if the received signal strength exceeds the switch threshold and may switch to the stronger carrier if the received signal strength is below the switch threshold. This carrier switching scheme may prevent the terminal from switching to the strongest carrier when the assigned carrier can provide satisfactory performance. The access network may also switch the terminal to another carrier by sending a carrier switch message.
摘要翻译：描述用于在多载波接入网络中执行载波切换的技术。例如在系统接入或切换期间由接入网络将终端分配给具有不同发射功率电平的多个载波之中的载波。终端可以从接入网接收切换阈值。终端可以周期性地测量所分配的载波的接收信号强度，并且可以将接收到的信号强度与开关阈值进行比较。如果接收到的信号强度超过开关阈值，则终端可以避免切换到更强的载波，并且如果接收到的信号强度低于开关阈值，则可以切换到更强的载波。当分配的载波可以提供令人满意的性能时，该载波切换方案可以防止终端切换到最强的载波。接入网络还可以通过发送载波切换消息来将终端切换到另一载波。

摘要： Wireless communications methods and apparatus are described. A communications apparatus, e.g., a base station, measures interference information, e.g., other sector interference information. The communications apparatus generates a preamble which includes a plurality of pilot symbols and at least one of the pilot symbols includes interference information. In some embodiments, the preamble is part of a superframe structure, e.g., a recurring superframe structure, including the preamble and a plurality of frames, at least some of the frames used to convey traffic data. The communications apparatus transmits the preamble, thus broadcasting the interference information to access terminals in the vicinity. An access terminal receives the preamble including a plurality of pilot signals, at least one of the pilot signals including interference information. The access terminal recovers the interference information from the received preamble and controls signal transmission based on the recovered interference information.

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： 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.
