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： An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

摘要： Systems and methodologies are described that facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection. In measuring and ranking surrounding access points in reselection, offsets can be applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements (and thus ranking) of some access points. Moreover, hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point.
摘要翻译：描述了有助于应用偏移和/或可选滞后值以有利于小区重选中的接入点的系统和方法。在重选中测量和排列周围接入点时，可以将偏移量应用于有利的接入点，以促进小区重新选择。在某些情况下，偏移可以积极地影响测量，并因此排列。负偏移也可以应用于某些接入点的较低测量（并因此排序）。此外，滞后值可用于测量电流单元，以防频繁重新选择。滞后值可以根据当前单元格或相关接入点的类型进行选择，以扩大覆盖范围。因此，当前接入点是有利的，可以将更大的滞后加到与当前接入点相关的测量中。

摘要： A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.

摘要： Systems and methodologies are described that facilitate resolving resource assignment conflicts between access terminals in a wireless communication environment. A first access terminal may receive a persistent, or “sticky” assignment of a set of resources, such as subcarriers. In the event that a second access terminal requires a brief resource assignment, a time-limited, or “non-sticky” resource assignment may be granted to the second access terminal. If a resource in the non-sticky assignment is already assigned to the first access terminal via the sticky assignment, the first access terminal may receive an indication of the conflict along with information related to a duration of the non-sticky assignment, may surrender the conflicted resource, and may resume control over the conflicted resource after the termination of the non-sticky assignment.

摘要： Methods and apparatus for communicating packets of information from an access terminal to a remote access node assembly by way of a serving access node assembly are described. An inter-route tunneling protocol module which interfaces with a radio link protocol module is used to tunnel route protocol packets. A first radio link protocol stream is associated with an application resident on the access terminal. A second radio link protocol stream is associated with an inter-route tunneling protocol module. Information to be communicated to a remote access node assembly by way of a serving access node assembly is subjected to two different radio link protocol processing operations. A first one of the RLP processing operations corresponds to the remote access node assembly while the second RLP processing operation corresponds to the serving access node assembly.

摘要： Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.
