摘要： Problems caused by interaction between paging optimization and synchronizing closed subscriber group (CSG) information are mitigated by setting a network indication indicating, for example, that a subscriber is no longer a member of a CSG, but the network has not yet received confirmation that an access terminal associated with the subscriber has been informed of this. A timer-based scheme may be employed for removing a CSG identifier (ID) from the subscriber information for a subscriber once it is determined that the subscriber is no longer a member of the CSG. In addition, a temporary member of a CSG may determine whether it is still a member of a CSG upon expiration of a CSG timer. Also, the frequency with which an access terminal registers may be changed based on various criteria. Furthermore, an allowed CSG list may be selectively included in a page message depending on the destination of the page message.

摘要： Systems and methodologies are described that facilitate scheduling over multiple hops in a wireless communication network. Radio resources can be partitioned into sets of sub-frames that can be allocated statically and/or dynamically. Statically allocated radio resources can be reassigned over time based on the loading on each hop and/or throughput imbalance. In addition, dynamic assignment of sub-frames to each hop can be based on traffic or channel conditions. Moreover, the radio resources can be dynamically allocated in a distributed scheme, wherein a base station controls the scheduling of resources, or a centralized scheme, wherein a relay station controls the scheduling of resources. Furthermore the allocation of radio resources can be transparent or explicit. In the transparent case, the access terminal listens directly to the base station, and the relay station does not transmit control information, such as DL or UL assignments. Conversely, when the allocation of resources is explicit the relay station does transmit control information.

摘要： Local breakout is provided by one or more nodes (e.g., a local access point and/or a local gateway) in a wireless network to facilitate access to one or more local services. In conjunction with local breakout, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service.

摘要： In-band provisioning enables subscribers to manually provision themselves via an access point at which the subscribers would not otherwise be allowed access. For example, a subscriber may be temporarily accepted by a restricted access point (e.g., an access point that belongs to a closed subscriber group). The subscriber is then given limited access to enable the subscriber to be provisioned at the access point. For example, the subscriber may be provisioned for full access at the access point if the subscriber presents a valid authorization credential to a provisioning entity.

摘要： Systems and methodologies are described that facilitate compressing packet headers for cell relay communications. Since cell relays can support a number of evolved packet system (EPS) bearers over a given dedicated radio bearer (DRB), robust header compression (RoHC) can be multiplexed for communications to/from a given cell relay. Thus, an upstream node compressing one or more packet headers can indicate a RoHC context, which can be represented by a RoHC context identifier in a RoHC header. A receiving entity can decompress the headers based on determining the RoHC context. Alternatively, the RoHC context can be associated with an identifier of a related UE bearer such as a tunnel endpoint identifier (TEID), a relay identifier, and/or the like, that is received in a tunneling protocol header to facilitate packet routing.

摘要翻译： 描述了便于压缩用于小区中继通信的分组报头的系统和方法。 由于小区中继可以通过给定的专用无线电承载（DRB）来支持多个演进的分组系统（EPS）承载，因此可以将稳健的报头压缩（RoHC）复用以用于/从给定小区中继的通信。 因此，压缩一个或多个分组报头的上游节点可以指示可由RoHC报头中的RoHC上下文标识符表示的RoHC上下文。 接收实体可以基于确定RoHC上下文来解压缩报头。 或者，RoHC上下文可以与在隧道协议报头中接收以便于分组路由的相关UE承载的标识符相关联，例如隧道端点标识符（TEID），中继标识符等等。

摘要： Systems and methodologies are described that facilitate assigning TEIDs, or portions thereof, to UEs or other devices during network attachment and/or dedicated bearer activation using one or more cell relays. Relay eNBs can request bearer establishment from a UE, which can be based on receiving an attach accept from an upstream node during attachment for the UE, receiving a bearer setup request from the upstream node, and/or the like. Once a bearer establishment response is received from the UE, the relay eNBs can store a TEID relating to the bearer. This can be a TEID that is at least partially received in the attach accept or bearer setup message, generated for the UE upon receiving the bearer establishment response, and/or the like. The TEID, or portion thereof, can be utilized for subsequent packet routing to the UE through one or more cell relays.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may send a first message to at least one interfering station to request reduction of interference on at least one resource. The first station may send the first message in anticipation of receiving data on the at least one resource. An interfering station may receive the first message from the first station and may reduce interference on the at least one resource by reducing its transmit power and/or by steering its power in a direction different from the first station. The first station may thereafter receive data from a second station on the at least one resource. The techniques may be used for data transmission on the forward and reverse links.

摘要： Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.
