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 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： Methods to manage multiple component carriers (CCs) efficiently in a mobile network with carrier aggregation (CA) enabled are proposed. For CC activation/deactivation, a single LCID value is used to represent both activation and deactivation command. A single command with multiple instructions is provided to activate and/or deactivate multiple CCs. In addition, unnecessary re-activation or re-inactivation of a CC is prevented, and explicit feedback for activation/deactivation is considered. For scheduling mechanism, a novel buffer status reporting (BSR) procedure is provided, where only one BSR is calculated after preparing all the transport blocks (TB) within one transmission time interval (TTI). Novel power headroom reporting (PHR) format and trigger are also provided. For DL-UL linking, various linking types are created based on whether there is carrier indicator field (CIF) in DL grant or UL grant. The various linking types are used in different applications to improve scheduling flexibility and load balancing.

摘要： A method of power control message indexing is provided in a wireless Orthogonal Frequency Division Multiple Access (OFDMA) network. A base station configures fast feedback channels (FFBCHs) and mobile stations report downlink channel information via the configured FFBCHs. Based on the received channel information, the base station estimates uplink channel quality and detects any channel variation. In response to uplink channel variation, the base station delivers power offsets to adjust the transmit power levels of the mobile stations. In one advantageous aspect, the power control commands for mobile stations are aggregated and the indexing scheme of the power control commands is implicitly based on the configured FFBCHs. For example, if a FFBCH is located at a first location in an uplink frame, then a following power control command in response to the FFBCH is located at a second location in a downlink frame, the second location is located after the first location with a predefined fixed delay time.

摘要： A network-based positioning mechanism is proposed. A serving BS first allocates radio resource to a target UE for network-based positioning in a wireless communication system. The target UE then transmits a positioning reference signal (PRS) to the serving BS and a plurality of cooperative BSs at the same time instant. All the cooperative BSs then conduct PRS detection and TOA measurements. Finally, the serving BS conducts positioning estimation based on the TOA measurement results. In one novel aspect, only one PRS transmission is required in one positioning opportunity for one positioning result. Candidates of PRS are selected with respect to different scenarios and allocated in a PRS resource region. Multiple positioning opportunities and multiple reference signals may be multiplexed over time, frequency or code domain in the PRS resource region. In one embodiment, the PRS is configured in such a way that both radio resource consumption and interference is minimized.
摘要翻译：提出了一种基于网络的定位机制。服务BS首先向无线通信系统中的基于用于基于网络的定位的目标UE分配无线电资源。目标UE然后在同一时刻向服务BS和多个协作BS发送定位参考信号（PRS）。所有合作BS随后进行PRS检测和TOA测量。最后，服务BS基于TOA测量结果进行定位估计。在一个新颖的方面，在一个定位结果的一个定位机会中仅需要一个PRS传输。针对不同场景选择PRS的候选者，并分配在PRS资源区域中。多个定位机会和多个参考信号可以在PRS资源区域中随时间，频率或代码域被复用。在一个实施例中，PRS被配置为使得无线电资源消耗和干扰都被最小化。

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： 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.
