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： In an LTE/LTE-A system, a UE subscribes to an MBMS service in a source cell. In one embodiment, the UE with ongoing MBMS service handovers to a target cell. The UE obtains MBMS information of the target cell before or after the handover. The UE then determines MBMS service continuity in the target cell based on the obtained MBMS information. In another embodiment, the UE with ongoing MBMS service reselects a new cell. The UE makes cell reselection decision based on obtained MBMS information of its neighbor cells. If the subscribed MBMS service is discontinued after handover or cell reselection, the UE releases MBMS bearer and informs a NAS entity. If the subscribed MBMS service is available after handover or cell reselection, the UE keeps MBMS bearer during handover or cell reselection. By acquiring MBMS information, the UE is able to maintain continuous MBMS reception after handover or cell reselection.

摘要： A method for contention-based (CB) uplink transmission in a wireless communication network is provided. A base station (eNB) first transmits CB configuration information and CB grant to a user equipment (UE). The UE derives a plurality of transmission opportunities from the uplink CB grant and in response transmits uplink CB data via one of the transmission opportunities. The UE then receives an acknowledgment from the serving base station. If the uplink CB data is non-decodable by the eNB due to multiple contention UEs, then the UE retransmits the uplink data in response to a negative acknowledgment. In one novel aspect, the uplink transmission radio resource carriers both the uplink CB data and UE-selected signature information. In one embodiment, the UE-selected signature information is transmitted via pilot tones. By eliminating a separate phase of contention resolution, the overall latency of CB transmission is reduced and transmission efficiency is improved.

摘要翻译： 提供了一种在无线通信网络中基于争用（CB）上行链路传输的方法。 基站（eNB）首先向用户设备（UE）发送CB配置信息和CB授权。 UE从上行链路CB授权中导出多个传输机会，并且响应于传输机会中的一个发送上行链路CB数据。 然后，UE从服务基站接收确认。 如果上行CB数据由于多个争用UE而被eNB无法解码，则UE响应于否定确认重发上行链路数据。 在一个新颖的方面，上行链路传输无线电资源承载上行链路CB数据和UE选择的签名信息。 在一个实施例中，经由导频音发送UE选择的签名信息。 通过消除争用解决的单独阶段，CB传输的总体延迟降低，传输效率提高。
