摘要:
Short spreading is used within a random access channel in an OFDM based network to spread data for transmission through the channel. The resource allocation of the random access channel is divided into a number of resource blocks in frequency, time, or both frequency and time. Each resource block has a dimension that is only a portion of the overall size of the resource allocation. During contention, a randomly selected short spreading code may be used to provide data spreading within a randomly selected resource block.

A wireless communication system and method schedules a beginning of an uplink transmission from a wireless device to a network transceiver with a first predetermined period of time after an end of a downlink transmission from the network transceiver device to the wireless device is scheduled. The uplink transmission and the downlink transmission comprise the same carrier frequency. The first predetermined period of time is related to a time required for the wireless device to switch from between receive and transmit modes. A beginning a downlink transmission from the network transceiver to the wireless device is scheduled with a second predetermined period of time after an end of an uplink transmission from the wireless device to the network transceiver is scheduled. The second predetermined period of time is related to a time required for the wireless device to switch between transmit and receive modes.

A method and an information handling system configured to select a mobility anchor point for a mobile device in a distributed mobility anchor point network may comprise collecting information about movement behavior or data transfer behavior of the mobile device, or tunneling overhead of two or more base stations. A mobility anchor point associated with a first base station may be assigned to the mobile device if the mobile device is connected to the first base station for at least a predetermined amount of time, if the mobile device transfers at least a predetermined amount of data via the first base station, or device if a tunneling overhead of the first base station is less than a predetermined level. In some embodiments, a centralized mobility anchor may be assigned to the mobile device if the mobile device is highly mobile and there is no identified base station to which the mobile device is frequently connected.

Techniques are disclosed that involve the indication of neighbor base stations. For instance, a base station may generate and wirelessly transmit a message that indicates a plurality of neighboring base stations. This message may include an indicator having one or more wildcard values. Through the employment of such wildcard values, the indicator may provide information corresponding to the plurality of neighboring base stations. For instance, the indicator may indicate a plurality of base station identifiers (BSIDs). Alternatively, the indicator may indicate a plurality of preamble indices. As a further alternative, the indicator may indicate a plurality of carrier frequencies. Through the employment of such techniques, overhead can be saved without causing ambiguity in mobility management.

Efficient paging operation for femtocell deployment is generally presented. In this regard, a paging controller is introduced including a wired backbone interface to communicate with a plurality of macro base stations and a plurality of femto base stations, and control logic, the control logic to generate a page for a mobile station, and the control logic to transmit the page over the wired backbone interface to a select subset of all base stations, wherein the select subset of all base stations includes base stations that the mobile station is authorized to access. Other embodiments are also described and claimed.

A method and system to facilitate mobile relay and group mobility in a wireless network. In one embodiment of the invention, the wireless network facilitates a mobile relay station that has logic to switch communication with a first base station to a second base station while maintaining logical communication with its associated mobile station(s). By doing so, the handover of the mobile relay station from a source base station to a target base station is transparent to the mobile station(s) that are connected with the mobile relay station in one embodiment of the invention.

Advertising in connection with handing off a cell from one cell to another may be facilitated by segregating communication descriptors into a common part that does not change in different types of cells and a unique part that changes in different types of cells. The unique parts may be advertised more frequently than the common parts.
