摘要： Exclusion functionality for License Assisted Access, LAA, in LTE is defined. LAA exclusion is a temporary deactivation or throttling of scheduling on LAA Secondary Cells (SCells), which allows a requesting UE (11) to periodically, or upon demand, send data or perform measurements on Wi-Fi networks using the same receiver circuitry (18), e.g., radio front end, without risk of losing LAA traffic. A UE sends an exclusion request to its serving base station, eNB (31) and receives an acknowledgement. The UE (11) may include parameters, e.g., duration or periodicity, in the request, and the acknowledgement may include overriding parameters. By the introduction of the exclusion functionality, the UE (11) can share receiver circuitry (18) between Wi-Fi and LAA, hence reducing hardware device size, cost, and power consumption.
摘要翻译：定义LTE中的许可协助接入LAA的排除功能。 LAA排除是LAA辅助小区（SCell）上的调度的临时去激活或节制，其允许请求UE（11）周期性地或者根据需要在使用相同接收机电路（18）的Wi-Fi网络上发送数据或执行测量），例如无线电前端，而没有丢失LAA业务的风险。 UE向其服务基站eNB（31）发送排除请求并接收确认。 UE（11）可以在请求中包括参数（例如，持续时间或周期性），并且确认可以包括超越参数。通过引入排除功能，UE（11）可以在Wi-Fi和LAA之间共享接收器电路（18），从而减少硬件设备尺寸，成本和功耗。

摘要： A network node (110) and method therein for evaluating a channel in a License Assisted Access, LAA, cell in a wireless communication network (100) are disclosed. The network node starts a Listen Before Talk, LBT, procedure for data transmission when a Discovery Reference Signal, DRS, is to be transmitted; and start an LBT procedure for DRS transmission in parallel with the LBT procedure for data transmission when a time of the LBT procedure for data transmission reaches a predefined value or the LBT procedure for data transmission fails.

摘要： A network node (120) and method therein for performing multi-channel access procedures in a License-Assisted Access, LAA, cell in a wireless communication network are disclosed. The network node selects one carrier as a master carrier and starts a Listen Before Talk, LBT, channel sensing for all carriers at a same or different point in time. The network node further stores LBT channel sensing results for all carriers for at least the last two slot durations of a subframe and checks if the LBT channel sensing on the master carrier is successful based on its LBT channel sensing result. When the LBT channel sensing on the master carrier is successful, the network node checks the LBT channel sensing results for all other carriers, and transmits on the master carrier and the carriers where the LBT channel sensing is successful at the subframe boundary or earlier than the subframe boundary. When the subframe boundary of the master carrier is reached and the LBT channel sensing on the master carrier is not successful, the network node transmits on the carriers where the LBT channel sensing is successful at the subframe boundary or earlier than the subframe boundary.

摘要： The present disclosure relates to a network device and methods for broadcasting a system information message that is associated with a time window. More particularly the disclosure pertains to ensuring reception of a SI message in a UE. In particular, the disclosure relates to a method, performed in a network node, for broadcasting a system information message that is associated with a time window 34. The method comprises detecting S1 that the system information, SI, message is of a predetermined message type, transmitting S2 the system information message in a first subframe 35a of the associated time window, and transmitting S3 the system information message in at least one second subframe 35b of the associated time window, in response to the detection that the system information message is of a predetermined message type.
