摘要： A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In a first embodiment, LIPA information is statically configured in the UE. In a second embodiment, LIPA information is informed to the UE via broadcasting or unicasting Radio Resource Control (RRC) signaling.

摘要： A method of UE RSRQ measurement precaution for interference coordination is provided. The UE receives radio signals of a neighbor cell under measurement. The neighbor cell applies a TDM silencing pattern for inter-cell interference coordination (TDM ICIC). The UE determines a measurement pattern that includes multiple subframes. The UE performs RSRQ measurements of the cell over multiple subframes and obtains multiple RSRQ measurement samples. The UE derives RSRQ measurement result by estimating the multiple RSRQ samples and applying a weighted average. RSRQ samples estimated to be more applicable are taken into account to more extent (e.g., applied with more weight), and/or RSRQ samples estimated to be less applicable are taken into account to less extent (e.g., applied with less weight, or discarded with zero weight). With UE precaution, a more predictable RSRQ measurement result is produced.

摘要： A power control method to mitigate in-device coexistence (IDC) interference is provided. A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference, the UE applies power control method to mitigate the interference. In a first embodiment, the LTE radio module adjusts its power parameters locally without informing the serving eNB. In a second embodiment, the LTE radio module adjusts its power parameters and implicit informs the eNB through existing PHR reporting. In a third embodiment, the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput.

摘要： A method of inter-cell interference coordination is provided for UE measurements and network access procedure. In a first embodiment, a UE in idle mode performs measurements on received radio signals applying a simplified radio resource restriction for interference coordination. The UE determines the restricted radio resource without receiving explicit measurement configuration. In a second embodiment, during various phases of a network access procedure, the UE indicates its interference status and/or additional interference information to its serving base station to enhance interference coordination. In a third embodiment, the UE in connected mode performs measurements on both interference-protected transmission resources and non-interference-protected transmission resources. The UE measurement results are used for scheduling, radio link monitoring, and/or mobility management to increase radio spectrum efficiency and to improve user experience.

摘要： A method of multi-set RRC signaling for ap-SRS configuration is provided to enhance ap-SRS flexibility. An eNB transmits a plurality of sets of UE-specific SRS parameters to a UE via upper layer messaging in a multi-carrier wireless communication system. The eNB also determines triggering information of a selected set of UE-specific SRS parameters and an indicated carrier for the UE. The eNB then transmits an uplink or downlink grant over a primary carrier, the grant comprises triggering information for the UE to send an ap-SRS over the indicated carrier using the selected set of UE-specific SRS parameters. In one embodiment of joint signaling, the plurality of sets of UE-specific SRS parameters are signaled together in a single RRC transmission. In another embodiment of separate signaling, each set of UE-specific SRS parameters is signaled independently.

摘要： Network-assisted solutions are provided to maintain MBMS service continuity, to provide efficient localized MBMS service, and to achieve intelligent MBMS service management. In a first embodiment, a source eNB acquires MBMS information of neighbor cells and acquires MBMS reception/interest status information of a UE. Based on the acquired information, the source eNB makes handover decision for the UE to handover to a selected target cell and maintain MBMS service continuity. In a second embodiment, location information of a localized MBMS service is provided to a UE. Based on the location information, the UE is able to receive the localized MBMS service with minimum power consumption. In a third embodiment, an MBMS counting procedure is provided for an eNB to count the number of UEs that are receiving or are interested in MBMS service(s). Based on the counting result, the MBMS service(s) can be enabled or disabled accordingly.

摘要： A cell reselection method and system using an active measurement set in a mobile communication, which determines whether the user equipment enters in a power-saving mode based on the signal strength and strength variability of a serving cell and the mobile feature of a user equipment. In the power-saving mode, in accordance with the signal strength of neighboring cells on the serving cell, an active measurement set is formed with cells that are selected from the neighboring cells broadcasted by a WCDMA system and have stronger signals. The user equipment only requires measuring the cells in the active measurement set. Thus, since the cell number of the active measurement set is smaller than that defined by the WCDMA system, the number of neighboring cells required to be measured is reduced, so as to reduce the power dissipation and increase the idle time on the user equipment.
摘要翻译：一种在移动通信中使用主动测量集的小区重选方法和系统，其基于服务小区的信号强度和强度可变性以及用户设备的移动特征来确定用户设备是否进入功率节省模式。在省电模式下，根据服务小区的相邻小区的信号强度，由从WCDMA系统广播的相邻小区中选择的小区形成有源测量集，并具有较强的信号。用户设备只需要测量主动测量组中的单元。因此，由于有源测量集合的小区数小于由WCDMA系统定义的小区数，所以需要测量的相邻小区的数量减少，从而降低功耗并增加用户设备上的空闲时间。

摘要： Methods and systems for providing fast handoff in WLAN-like communications system construct a caching candidate set based upon a weighted handoff tendency coefficient. The weighted handoff tendency coefficient is based upon the handoff matrix and the weighting factor. The handoff matrix is an adaptive two-dimensional array that provides a list of nearby access points relative to a mobile station and the weighting factor is a value that prioritizes the nearby access points based upon a signal quality indication. A home access point, once it is triggered to initialize proactive caching, provides the caching candidate set with registration data of the mobile station before a transfer of a connection between the home access point and one of the access points on the caching candidate set.
