Abstract: A method of offload selection for a UE to select between 3GPP RAT and WLAN cell is provided. The UE receives configuration information that applies to selecting WLAN or 3GPP radio access technology (RAT). The UE determines if the UE may perform WLAN offload by evaluating 3GPP radio access network (RAN) conditions where at least one RAN condition is related to a radio signal strength or a radio signal quality in 3GPP RAT. The UE then determines if there is at least one suitable WLAN cell by evaluating WLAN conditions. The UE also determines if there is candidate traffic for WLAN offload. Finally, the UE steers the determined traffic to WLAN if the UE may perform WLAN offload and if there is at least one suitable WLAN cell. Otherwise, the UE steers the determined traffic to 3GPP RAT.

Abstract translation: 提供了一种用于UE在3GPP RAT和WLAN小区之间进行选择的卸载选择的方法。 UE接收适用于选择WLAN或3GPP无线电接入技术（RAT）的配置信息。 UE通过评估其中至少一个RAN条件与3GPP RAT中的无线电信号强度或无线电信号质量相关的3GPP无线电接入网络（RAN）条件来确定UE是否可以执行WLAN卸载。 然后，UE通过评估WLAN条件来确定是否存在至少一个合适的WLAN小区。 UE还确定是否存在用于WLAN卸载的候选业务。 最后，如果UE可以执行WLAN卸载并且如果存在至少一个合适的WLAN小区，则UE将所确定的流量引导到WLAN。 否则，UE将确定的业务引导到3GPP RAT。

Abstract: A method of collecting and providing traffic statistics in a cellular network in accordance is proposed. A UE establishes an RRC connection with a base station. The UE starts to collect traffic statistics that comprises a CDF curve or a PDF diagram for packet inter-arrival time. The UE may receive a measurement configuration from the base station for the traffic statistics collection. The UE then reports a representation of the traffic statistics to the base station for RRC reconfiguration. The UE may also receive a reporting request from the base station that specifies a representation format. The representation format includes one or more probability values at corresponding inter-arrival time points, at least one slope of the CDF, one or more steep events in the CDF, or a PDF range.

Abstract: Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are coexisted/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

Abstract: A method of uplink shaping and extending UE in RRC Idle Mode is proposed. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE enters RRC Connected mode and thereby transmitting the data packet to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and the UE is prohibited from entering RRC Connected mode until a triggering condition is satisfied for uplink transmission. The proposed mechanism achieves power saving by reducing the activity of uplink transmission. In addition, the proposed mechanism also reduces signaling overhead to enhance network efficiency.

Abstract translation: 提出了一种在RRC空闲模式下上行整形和扩展UE的方法。 UE处理要发送到网络的数据包。 数据包与流量类型相关联。 如果数据包属于正常流量类型，则UE进入RRC连接模式，从而将数据包发送到网络。 如果数据包属于后台流量类型，则UE缓存数据包，并且禁止UE进入RRC连接模式，直到满足上行链路传输的触发条件为止。 提出的机制通过减少上行传输的活动实现节电。 此外，所提出的机制还减少了信令开销以提高网络效率。

Abstract: A method of cell reselection enhancement is proposed. A UE obtains parameters for extended cell reselection (ECR) in a mobile communication network. The UE goes to sleep and then wakes up periodically to monitor a paging channel. The UE either applies a normal paging cycle having a normal paging cycle length or applies a power-saving paging cycle having a very long paging cycle length. The UE performs cell selection if normal paging cycle is applied. The UE performs cell reselection based on the ECR parameters if the power-saving paging cycle is applied, and if the ECR parameters are still valid based on a list of conditions. In one novel aspect, the network provides the ECR parameters for a wider area for the UE such that the UE can still use cell reselection after waking up from a very long sleep to reduce power consumption.

Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. In one embodiment, the access information comprises mapping information between the TMGI and the communication group ID.

Abstract: A method and apparatus for UE to report preference indication and other UE assistance information to the network is proposed. In a first embodiment, the UE transmits a power preference indication to the network with a prohibition mechanism for optimal DRX configuration. A first level of prohibition is applied if the UE indicates preferring power-saving mode, and a second level of prohibition is applied if the UE indicates preferring normal mode. In a second embodiment, the UE transmits two-level speed information to the network. The two-level speed information is mapped from MSE mobility states based on a mapping rule. In a third example, the UE transmits RRC release assistance information to the network. The assistance information is based on both cell change count and RRC state transition count so that RRC inactivity time can be determined to reduce signaling overhead.

Abstract: A method of user equipment (UE) providing speed information to network is provided. The method supports obtaining speed information of the UE, detecting a trigger event and providing the speed information to the network by one or more predefined means. The speed information is taken from the group consisting of a physical speed, a physical speed mapped on a pre-defined speed group, and a virtual speed. The virtual speed comprises a cell change count or a number cells that the UE has requested RRC connection during a certain period. The UE can send the speed information to an eNB via RRC connection establishment, RRC connection re-establishment, a new IE in RRC measure report or a new RRC message.
