摘要： Autonomous uplink (UL) transmission can be enabled for user equipments (UEs) to generate on unlicensed spectrums that are shared among different UEs of a network. A UE can generate the autonomous UL transmission within a gap period of a transmission opportunity (TxOP) without a corresponding UL grant. The UE performs a listen before talk (LBT) operation within the gap period of a TxOP. Based on the LBT, the autonomous UL transmission can be communicated on an unlicensed channel that is shared among the different UEs.

摘要： Technology for a low mobility user equipment (UE) operable to perform uplink (UL) transmissions using configured grant (CG) physical uplink shared channel (PUSCH) resources is disclosed. The UE can decode a CG PUSCH resource configuration from an eNodeB while the low mobility UE is in a radio resource control (RRC) connected state. The CG PUSCH resource configuration can indicate CG PUSCH resources for the low mobility UE after the low mobility UE transitions from the RRC connected state to an RRC idle state. The UE can transition from the RRC connected state to the RRC idle state. The UE can encode data packets for transmission over a PUSCH to the eNodeB using the CG PUSCH resources while the low mobility UE is in the RRC idle state.

摘要： Technology for an eNodeB operable to perform physical random access channel (PRACH) transmissions in an unlicensed frequency band, in the context of 3GPP LTE eLAA, i.e. MuLTEfire, is disclosed. The eNodeB can identify a PRACH configuration being utilized by a MuLTEfire system that operates in an unlicensed spectrum. The PRACH configuration can define a number of continuous physical resource blocks (PRBs) in the unlicensed spectrum to be used for PRACH transmissions. The eNodeB can decode a PRACH transmission received from a user equipment (UE) in accordance with the PRACH configuration. The PRACH transmission can include a PRACH preamble that is transmitted using the number of continuous PRBs defined in the PRACH configuration. The eNB configures the performance of Clear Channel Assessment, CCA, before preamble transmission by the UE. In case the uplink transmission frame is configured with short PUCCH, sPUCCH, only a short CCA is configured. Otherwise, for example when the frame allows ePUCCH to be configured, CCA is followed by a self-deferring period.
摘要翻译：公开了一种用于eNodeB的技术，该eNodeB可操作用于在3GPP LTE eLAA的上下文（即，MuLTEfire）中执行无执照频带中的物理随机接入信道（PRACH）传输。 eNodeB可以识别在非授权频谱中运行的MuLTEfire系统正在使用的PRACH配置。 PRACH配置可以定义要用于PRACH传输的未经许可的频谱中的多个连续物理资源块（PRB）。 eNodeB可以根据PRACH配置对从用户设备（UE）接收到的PRACH传输进行解码。 PRACH传输可以包括使用在PRACH配置中定义的连续PRB的数量传输的PRACH前导码。 eNB在UE的前导码传输之前配置空闲信道评估CCA的性能。在上行传输帧配置有短PUCCH，sPUCCH的情况下，只配置短的CCA。否则，例如，当帧允许配置ePUCCH时，CCA后面是自我推迟期。
