摘要： A UE determines a first DCCH resource candidate in a first CORESET on a carrier, the first DCCH resource candidate including a first set of RBs. The UE also determines a first sequence of DMRSs that are mapped, starting at a reference point, to RBs in a predetermined range within the carrier in a frequency domain, the predetermined range containing the first DCCH resource candidate in the frequency domain. The UE further determines a first reference location of the first set of RBs. The UE determines, based on the first reference location, a first set of DMRSs from the first sequence of DMRSs, the first set of DMRSs being mapped to the first set of RBs. The UE obtains a channel estimation based on the first set of DMRSs; and The UE performs blind decoding of the first DCCH resource candidate based on the channel estimation.

摘要： A method of dynamic spectrum sharing mechanism called listen-before-talk (LBT) is proposed for uplink transmission in Licensed Assisted Access (LAA). A maximum channel occupancy time (MCOT) including downlink (DL) transmission from one eNB and uplink (UL) transmission to the same eNB is introduced. A transmission sequence is defined as a number of subframes including possible partial subframes for DL and/or UL within a MCOT. The transmission in the first subframe among the transmission sequence is conducted after a Category 4 LBT. The transmission sequence within the MCOT can be initiated by either a DL transmission or an UL transmission. After the first subframe in a transmission sequence, LBT for another transmission is a fast DL LBT and/or fast UL LBT. Further, a Category 4 LBT can be converted to a short LBT (e.g., one shot CCA) for more efficient channel access.
摘要翻译：针对许可辅助接入（LAA）中的上行链路传输，提出了一种叫做先听后说（LBT）的动态频谱共享机制。引入了包括来自一个eNB的下行链路（DL）传输和到同一eNB的上行链路（UL）传输的最大信道占用时间（MCOT）。传输序列被定义为包括用于MCOT内的DL和/或UL的可能部分子帧的多个子帧。传输序列中的第一个子帧中的传输是在类别4 LBT之后进行的。 MCOT内的传输序列可以由DL传输或UL传输启动。在传输序列中的第一个子帧之后，用于另一传输的LBT是快速DL LBT和/或快速UL LBT。此外，类别4LBT可以转换为短LBT（例如，单次CCA）以获得更高效的信道接入。

摘要： Methods and apparatus are provided for multiplexing DRS within a transmission burst for opportunistic spectrum access. In one novel aspect, DRS is not transmitted in a fractional subframe within a TXOP. In one embodiment, if the starting fractional subframe, which contains initial signal, occurs in a configured DMTC, DRS is transmitted in the first subframe next to the starting fractional subframe. In another embodiment, if DMTC starts from a complete subframe within a TXOP, DRS is transmitted in the first candidate position within a DMTC. In another novel aspect, in the DRS subframe, PDSCH is allocated in the PRBs outside the central PRBs (six or twenty-five PRBs). In one embodiment, the reservation signal can be used to satisfy the requirement of occupied bandwidth and continuity transmission. In another embodiment, the free REs in central PRBs carry the system information when required on the unlicensed band.

摘要： Methods and apparatus are provided for improved Licensed Assisted Access (LAA) networks. A LAA subframe is received via an unlicensed frequency band. Control information is communicated via predetermined symbol locations within the LAA subframe. An indication of a first and a second symbol locations is received. A LAA subframe is then received. It is determined if control information is present at the first or second symbol locations within the received LAA subframe. Demodulation parameters based on the control information are determined. The LAA subframe is demodulated using the demodulation parameters. An indication of a transmission duration is communicated to a UE. The transmission duration is determined based on the LAA subframe. A type of subframe is determined based on transmission duration. Automatic Gain Control (AGC) protection is provided in a LAA subframe. The AGC protection LLA subframe does not communicate control information in a symbol adjacent to a reservation signal.

摘要： In one novel aspect, a plurality of synchronization signal (SS) anchors within a block of a contiguous spectrum is configured in a wireless network, wherein each SS anchor is a primary SS anchor or a secondary SS anchor. The UE performs an initial access by detecting a first primary SS anchor and receives one or more virtual carrier configurations with corresponding SS anchors within the block of the contiguous spectrum. In another novel aspect, The UE performs an initial access through a first RF band with a first bandwidth and a first center frequency, receives a switching signal to switch from the first RF band to a second RF band with a second bandwidth and a second center frequency, wherein the second bandwidth is different from the first bandwidth, and performs a RF bandwidth adaptation from the first RF band to the second RF band based on the adaptation signal.

摘要： Methods and apparatus are provided for control overhead reduction. The UE configures one or more short transmission time interval regions over a normal TTI region shared by the UE and one or more other, each UE includes a self-contained control information sPDCCH occupying a control information region. The UE detects a cover signal, which indicates one or more resource elements in the sPDCCH control-information region that can be used for data transmission. The UE obtains data transmission from the REs in the SPDCCH control information region based on the detected cover signal. In one embodiment, the cover signal is a dedicated signal. In another embodiment, the cover signal is a common signal. In yet another embodiment, the cover signal is encoded in a downlink control information (DCI) intended for the UE. In one embodiment, the cover signal indicates one or more CCE REs to be excluded for data transmission.
