摘要： The present invention provides a method and an apparatus for a wireless communication between at least one mobile station and a base station in a cellular system. The method comprises providing a desired spreading in time and frequency domains to transmit data using at least two carriers in a transmission on an uplink to the base station. Either the base station may provide an indication to the mobile station to enable the desired spreading, or alternatively, the mobile station may request it. A spread-spectrum cellular system may enable a mobile station to provide a two-dimensional spreading, which distributes spreading in time and frequency directions. A single two-dimensional spreading code or at least two one-dimensional spreading codes may provide a two-dimensional spreading. In this way, in an uplink transmission using a multi-carrier, code division multiple access (MC-CDMA) protocol, by varying the data portions being spread in time and frequency domains a joint spreading may result. The joint spreading may distribute spreading codes in the time and frequency directions to distribute the spreading in a transmission. When using the MC-CDMA protocol, a mobile station may select one or more spreading formats in an uplink transmission that may increase the success rate of the packet transmission. Moreover, use of a particular spreading format in a flexible manner may reduce the packet delay and suppress intra-cell interference.
摘要翻译：本发明提供一种用于在蜂窝系统中的至少一个移动台与基站之间的无线通信的方法和装置。该方法包括在时基和频域中提供期望的扩展，以便在到基站的上行链路上的传输中使用至少两个载波来发送数据。基站可以向移动台提供指示以实现期望的扩展，或者替代地，移动台可以请求它。扩频蜂窝系统可以使移动台能够提供二维扩展，其在时间和频率方向上分布扩展。单个二维扩展码或至少两个一维扩展码可以提供二维扩展。以这种方式，在使用多载波，码分多址（MC-CDMA）协议的上行链路传输中，通过改变在时域和频域上扩展的数据部分，可能导致联合扩频。联合扩展可以在时间和频率方向上分布扩展码，以在传输中分布扩展。当使用MC-CDMA协议时，移动台可以在可能增加分组传输的成功率的上行链路传输中选择一个或多个扩展格式。此外，以灵活的方式使用特定的扩展格式可以减少分组延迟并抑制小区内干扰。

摘要： For use in a wireless network, a base station configured to communicate in the wireless network is provided. The base station includes a processor coupled to a transmitter and configured to generate a resource allocation message. The resource allocation message includes a plurality of fixed length fields, one or more primary variable-length fields, and a plurality of secondary variable-length fields. The one or more primary variable-length fields occupy a position in the resource allocation message preceding as many of the fixed length fields as permitted by rules that govern a structure of the resource allocation message. The one or more primary variable-length fields are positioned in the resource allocation message such that when the resource allocation message is partitioned and allocated across a sequence of basic units (BUs), every primary variable-length field appears in a smallest possible sequence of BUs starting from the first BU in the sequence.

摘要： When a subscriber station (SS) encounters interference caused an interfering base station (BS), the interference can be mitigated regardless of whether the interfering base station is a CSG-Closed BS or whether the SS is connected to a serving BS. If the SS is not connected to a serving BS and cannot access the interfering BS, the SS will signal the interfering BS directly to request the interfering BS to perform IM. If the SS is a legal user, and conditions to initiate IM are met, the interfering BS will perform IM until conditions to terminate IM are met. If the SS is connected to a serving BS, the serving BS will request the interfering BS to perform or terminate interference mitigation (IM) on behalf of the SS if certain conditions are satisfied.
摘要翻译：当用户台（SS）遇到干扰基站（BS）造成的干扰时，无论干扰基站是CSG闭合BS还是SS连接到服务BS，都可以减轻干扰。如果SS未连接到服务BS并且不能接入干扰BS，则SS将直接用信号通知干扰BS以请求干扰BS执行IM。如果SS是合法用户，并且满足启动IM的条件，则干扰BS将执行IM，直到符合终止IM的条件。如果SS连接到服务BS，则在满足某些条件的情况下，服务BS将请求干扰BS代表SS执行或终止干扰抑制（IM）。

摘要： A subscriber station can efficiently determine an accessible base station by scanning a subset of base stations based on an optimized list received from a serving base station. The subscriber station includes a white list that contains information regarding a number of closed subscriber group (CSG) base stations to which the subscriber station is subscribed. The subscriber station can transmit a request message that includes one or more of: indication of whether the detected identifier of the femto base station is in the whitelist or not; and its location information. In response, the base station can send a message that includes the nearby femtocells and whether the femtocell is accessible or inaccessible to the subscriber station. The femto base station can be designed to be in transmission off mode when none of its subscribers is in its coverage. The serving base station can select a set of the accessible femtocells to the subscriber station, and request the selected femtocells to monitor an uplink signaling of the subscriber station so that the femtocell can be awaken when the femtocell is in transmission off mode or be aware that the subscriber station is in proximity, if the uplink signaling is detected.
