Abstract:
In a first mode of dedicated control channel (DCCH) operation, a wireless terminal is allocated more segments than in a second mode. The wireless terminal uses different information bit to modulation symbol mapping in the different modes. On a per DCCH segment basis, the same number of modulation symbols are communicatd in either mode but more information bits are conveyed in the second mode. Information bits for a DCCH segment are partitioned into two subsets. The two subsets are used to generate another set, each of the two subsets and the another set are input to the same mapping function to generate three equal size sets of modulation symbols which are transmitted via the DCCH segment. Uplink tone hopping is used such that one of the equal size sets of modulation symbols for the DCCH segment uses the same tone but a different set uses a different tone.
Abstract:
Embodiments describe synchronizing access routers with wireless terminal state information. According to an embodiment is a wireless terminal that transmits a message that includes an address for at least two access routers. State change information can optionally be included in the message. According to another embodiment is an access router that receives a state change notification from a wireless device or another access router. The state change notification is updated in the access router. An acknowledgment confirming the updated state change may be sent to the wireless terminal. Dynamic state synchronization is provided with minimal communication with wireless terminal.
Abstract:
Systems and methodologies are described that facilitate supporting multiple connections associated with a wireless terminal. Notifications may be provided to a primary base station upon establishment and/or removal of connections between the wireless terminal and secondary base station(s). Additionally, the multiple connections may be evaluated and a preferred connection from the set of multiple connections may be utilized to transfer data to the wireless terminal over a downlink connection.
Abstract:
Methods and apparatus of efficient communication of resource allocation are described. A base station transmits a resource assignment message, e.g., a state transition message, to a wireless terminal including a first part, e.g., a base station assigned wireless terminal On state identifier, identifying a resource being assigned and a second part, e.g., an ON state mask, identifying a portion of the resource allocated to the wireless terminal. The same resource allocation message information also communicates one of a plurality of different modes of commanded On state operation. The resource allocation message structure supports flexible allocation of available resources facilitating a resource to be partitioned differently at different times accommodating current needs. A predetermined recurring channel structure and association of segments with particular mask bits, facilitates allocated control segments to be used unambiguously without the need to include an overhead wireless terminal identifier field with the control report bits being communicated.
Abstract:
Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split.tone mode use.
Abstract:
Methods and apparatus for improved beacon signaling in a wireless communication system are described. Information is encoded in the tone position of the beacon tone. The information encoded may include sector type, sector index and slope index, as well as some time index. The information is coded in the tone position so that any few of several beacons can be decoded in order to decode the information. The methods and apparatus described in the invention improve the robustness against frequency selective fading and do not require wireless terminals to establish synchronization for reliable base station detection.
Abstract:
Systems and methodologies are described that facilitate assigning a flow (e.g., IP flow) to a wireless network link from a bundle that includes a plurality of wireless network links. Assignments can be based upon characteristics associated with the flow and characteristics associated with the links. For example, a service class corresponding to the flow can be evaluated to determine flow related characteristics. Moreover, link related feedback can be analyzed to determine characteristics of the links.
Abstract:
Methods and apparatus related to assignment in a wireless communications system are described. A mobile is assigned an identifier and a mask value, e.g., as part of a state transition message. The mobile uses the assigned identifier and/or the assigned mask value in determining whether assignments included in assignment messages, e.g., traffic channel assignment messages, are directed to the wireless terminal. Predetermined associations between assignment slots, assigned segments, and/or mask values are utilized to limit control signaling overhead. Different groups of segments are available for assignment to different wireless terminals as a function of mask values. Different types of assignment messages use different amounts of information bits to convey the assignment. Some types of assignments use a wireless terminal identifier, while other types of assignments use a wireless terminal identifier and a mask identifier. The mask identifier, e.g., a single bit, allows for selection between a subset of the potential masks used in the system.
