Abstract: A method is provided for controlling communications between a base station and a mobile device. The method comprises transmitting dedicated rate control information to the mobile device within a common rate control communications system. For example, dedicated rate control information may be embedded in a data packet and delivered to the mobile device over a data channel. The mobile device may be configured to extract the embedded dedicated rate control information from the data packet and use the information to control aspects of its transmission, such as time slot and rate.

Abstract: A method for exploiting the diversity of a multi-carrier cellular system's frequency bands, for purposes of increasing network capacity, involves a base station transmitting a pilot signal on each frequency band to a plurality of mobile stations. Each mobile station measures the SIR of each pilot signal on the frequency bands, and this information is transmitted back to the base station. The base station may be configured to utilize this information in a number of manners, all of which are intended to increase channel capacity. For example, on each frequency band, the base station may transmit data signals only to those mobiles stations with the best signal quality on that frequency band. Additionally, the base station may transmit signals to one or more mobile stations across one or more frequency bands simultaneously, with transmissions on each band being adapted to the corresponding channel conditions.

Abstract translation: 为了增加网络容量，利用多载波蜂窝系统的频带的多样性的方法涉及基站在每个频带上向多个移动站发送导频信号。 每个移动站测量频带上每个导频信号的SIR，并将该信息发送回基站。 基站可以被配置为以多种方式利用该信息，所有这些信息旨在增加信道容量。 例如，在每个频带上，基站只能向那些在该频带上具有最佳信号质量的移动站发送数据信号。 另外，基站可以同时向一个或多个频带发送信号到一个或多个频带，每个频带上的传输适应相应的信道条件。

Abstract: 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.

Abstract translation: 当用户站（SS）遇到造成干扰基站（BS）的干扰时，可以减轻干扰，而不管干扰基站是否为CSG封闭BS，或SS是否连接到服务BS。 如果SS未连接到服务BS并且不能访问干扰BS，则SS将直接通知干扰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直到满足终止IM的条件。 如果SS连接到服务BS，则如果满足某些条件，服务BS将请求干扰BS代表SS执行或终止干扰减轻（IM）。

Abstract: A mobile station and base station are capable of communicating in a wireless network via a set of contiguous or non-contiguous sub-bands. The base station transmits a resource allocation to the mobile station. The resource allocation message includes a sub-band index (SBI) field, a number of messages field, a contiguous allocation indicator field, or a combination of these. Based on the SBI field, one or more of the number of messages field and contiguous allocation indicator field, the mobile station can identify the set of sub-bands allocated to it by the base station.

Abstract: 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.

Abstract: The present invention provides a method and an apparatus for adapting a data rate that a mobile station indicates to a base station for transmission on a forward link in a cellular system. The method comprises measuring a first value indicative of strength of at least one of a primary and a secondary pilot. The method further comprises compensating the first value indicative of strength of the pilot based on an offset to select a second value indicative of the data rate for the base station. The base station may determine an offset value for compensation and send an indication to the mobile station during the setup of the mobile station. When the mobile station connects to the base station, a measurement of a channel condition (i.e., pilot) may determine a revised data rate for transmission of a next data packet on the forward link.
