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： 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： Group resource management is provided utilizing assignment of resources in a persistent manner, which involves assigning a channel and resources to a user device for a specified interval while allowing users within the group to be multiplexed dynamically. A first bitmap is created that is a function of the number of users in the group and the number of channels assigned to that group. A second bitmap is created that has a number of bits equal to a number of “on” bits contained in the first bitmap. The second bitmap can assign a rate option or a size option, which is a function of a profile of a group member that corresponds to the bit. The rate option and size option can be indicated in each x-bit position in the second bitmap Both broadcast and multicast are supported.
