摘要： One method of wireless communication involves acknowledging that an anchor base station received a handover indication signal. Another method involves: receiving, from base stations of an active set, offset signals identifying a respective differences in time between a reference time and respective times when the base station received a ranging signal from a mobile station; and transmitting, to the mobile station, a ranging control signal in response to the respective offset signals. Another method involves transmitting, to a mobile station in response to an active set signal, a system configuration information signal including system configuration information of a base station in an active set. Another method involves determining an uplink control channel power parameter in response to channel condition signals received from base stations in an active set. Another method involves transmitting a control signal to base stations in an active set on respective control channels. Apparatuses are also disclosed.

摘要： The description herein relates to pilot designs for an Orthogonal Frequency Division Multiplexing (OFDM) based communication system. In the preferred embodiment, the communication system is one operating according to the IEEE 802.16m, or WiMax, standard. In general, an OFDM transmitter operates to insert pilot symbols into a resource of a transmit frame according to a predetermined staggered pilot symbol pattern defining pilot symbol locations within the resource of the transmit frame. The predetermined pilot symbol pattern is defined such that pilot symbols are located at or near time boundaries of the resource, at or near frequency boundaries of the resource, or both. By doing so, when generating a channel estimate for the communication channel between the OFDM transmitter and an OFDM receiver based on the pilot symbols, extrapolations needed to estimate the channel near the boundaries of the resource are optimized, thereby improving overall channel estimation accuracy.

摘要： Methods, base stations and access terminals for uplink signalling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted the resource request based on the resource request channel characteristics of the resource request channel upon which the resource request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.

摘要： A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection. Pilot signals with varying density configurations are provided to include low density symbol patterns for multiple contiguous resource blocks and high density symbol patterns for single resource blocks.

摘要： Apparatus and methods are provided for transitioning wireless devices between a plurality of states having increasing resource intensity from a least resource intensive state to a most resource intensive second state. All power-on wireless devices are ranked. A respective subset of the power-on wireless devices is assigned to each state, the power-on wireless devices of the subsets having rankings which increase with resource intensity of the state. Signalling is generated to the wireless devices to instruct them to implement any change in state. The priorities which are calculated for the purpose of state scheduling are preferably the same as those, or at least based upon the priorities used for packet scheduling.

摘要： The invention provides various schemes for negotiating communications between wireless mesh network nodes operating in accordance with the IEEE 802.11e standard. However, more generally, the invention can be operated in accordance with other communication standards.According to a broad embodiment of the invention, a method is provided in which meeting durations are divided into at least two portions, an uplink transmission portion and a downlink transmission portion. In order to protect the negotiation packets from collisions, the negotiation process is combined with the uplink and downlink data transmissions. In some aspects of the invention, the negotiation process is protected from collisions by using the transmission opportunity (TXOP) protocol that is available in the IEEE 802.11e standard. The inventive methods can be used with a contention based protocol or a contention free based protocol.According to another broad embodiment of the invention there is provided a wireless network node capable of implementing methods described for negotiating communications between neighbouring nodes.
