摘要： To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.

摘要： Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.

摘要： A wireless communication method and system are provided. A first wireless communication numerology, e.g., OFDM operating parameters, corresponding to a first operational mode is established. A second wireless communication numerology corresponding to a second operational mode is also established. The first wireless communication numerology is different than the second wireless communication numerology. One of the first operational mode and the second operational mode is selected. One of the first wireless communication numerology and the second wireless communication numerology corresponding the selected operational mode is used in which communication in the first operational mode and the second operational mode use substantially similar synchronization channels. The present invention also uses the same superframe structure for the first and second operational modes for Ultra-Mobile Broadband ('UMB') networks and the same frame structure for the first and second operational modes for Long Term Evolution ('LTE') networks.

摘要： Security in wireless communication networks that employ relay stations to facilitate communications between base stations and mobile stations is enhanced. In one embodiment, resource information provided to one or more relay stations from a base station or another relay station is encrypted prior to being delivered to the one or more relay stations. Only authorized relay stations are allocated an appropriate key necessary to decrypt the resource information. As such, only appropriate relay stations are able to access and use the resource information to effect communications directly or indirectly between the base stations and the mobile stations. In certain embodiments, the resource information is delivered between the various base and relay stations using either unicast or multicast delivery techniques.

摘要： The invention concerns methods, a mobile station and a network for updating locations of mobile stations to support fast call setup and reduce paging resource utilisation in wireless access networks. The method comprises the steps of : - starting a first timer when the mobile station enters a dormant state - while the first timer is counting and prior to its reaching a prefined value T1, sending a layer 2 location update message whenever the MS performs an idle handoff, or sending an MS page to the sector indicated by the most recent layer 2 location update message received from the MS, - starting a second timer when the first timer reaches T1 - while the second timer is running and prior to its reaching a predefined value T2, sending a layer 2 location update message whenever a further criterion is met, or sending an MS page to the sectors surroiunding the sector indicated in the most recently received layer 2 location update message consistent with the further criterion used, and - after the second timer has reached T2, sending no further layer 2 location update messages, or sending an MS page message to all network sectors. In a second embodiment, a sinle timer, which is reset after reaching T1, is employed in a similar location update-method.
