摘要： In a wireless communication system, user equipments (UEs) may be partitioned into different groups, e.g. based on spatial separation. UEs may use multiple access (MA) signatures that have low or no correlation to each other if the UEs are in the same group. The MA signatures used by one group of UEs may be more correlated with the MA signatures used by another group of UEs. If the UEs are partitioned into the different groups based on spatial separation, then the spatial separation between the different groups may assist in increasing the reliability of detection if two UEs in different groups use correlated MA signatures.

摘要： Methods and systems for dynamically activate and deactivate an allocated resource for a UE to make grant-free uplink transmission are provided. In one embodiment, a user equipment (UE) receives a Radio Resource Control (RRC) signal. The RRC signal specifies grant-free (GF) configuration information. The GF configuration information comprises an activation field and at least one other GF resource configuration field. The activation field indicates whether the UE may perform GF uplink (UL) transmissions without waiting for a downlink control information (DCI) message. Then, the UE performs a GF UL transmission in accordance with the GF configuration information in the RRC signal.

摘要： Methods and systems are provided for signaling for semi-static configuration in grant free uplink transmissions. Radio resource control (RRC) signaling is used to provide information from a base station to a user equipment (UE) that configure the grant free transmission resource to be used by the UE. In some implementations, the RRC signaling may be used in conjunction with system information that is transmitted to all UEs and/or Downlink Control Information (DCI) that the UE needs to access subsequent to the RRC signaling. In some implementations, the DCI includes an activation or deactivation indicator that the UE monitors to determine when the UE is allowed to transmit to the BS or should stop transmitting. Implementations allow for grant free transmission resources to be configured on an individual user based and a group basis.

摘要： Uplink synchronization may be achieved without adjusting for timing advance by using longer/larger cyclic prefix durations to compensate for differences in propagation delays, including the cell round-trip delays and environment based multipath delays. In this way, timing advance reference signaling may be omitted from the uplink transmissions. In some embodiments, the cyclic prefix duration is determined based on a characteristic of a base station's coverage area, such as a coverage area size or coverage area type. For example, a longer cyclic prefix length may be used when a base station has a larger coverage area than when the base station has a smaller coverage area. As another example, a different cyclic prefix length may be used for different coverage types.
摘要翻译：通过使用较长/较大的循环前缀持续时间来补偿传播延迟的差异（包括小区往返延迟和基于环境的多径延迟），可以实现上行链路同步而无需调整时间提前量。以这种方式，可以从上行链路传输中省略定时提前参考信令。在一些实施例中，循环前缀持续时间基于基站的覆盖区域的特性（诸如覆盖区域大小或覆盖区域类型）来确定。例如，当基站具有更大的覆盖区域时，可以使用比基站具有更小的覆盖区域时更长的循环前缀长度。又如，不同的循环前缀长度可以用于不同的覆盖类型。

摘要： System and methods are disclosed in which pilots are used to assist in identifying grant-free uplink transmissions originating from the same UE. In one embodiment, a base station receives a grant-free uplink transmission that carries initial data from a user equipment and an initial pilot. The initial pilot is successfully decoded and the initial data is unsuccessfully decoded. The successfully decoded initial pilot and the unsuccessfully decoded initial data are stored in memory. Another grant-free uplink transmission carrying retransmission data from the user equipment and a retransmission pilot is then received. The retransmission pilot is successfully decoded and used to identify the successfully decoded initial pilot in the memory and the unsuccessfully decoded initial data. The retransmission data and the unsuccessfully decoded initial data are used to successfully decode the initial data.

摘要： It is possible to reduce the implementation complexity associated with dynamic carrier configuration by defining overlapping sets of candidate numerologies for at least some carriers in the network. A common numerology is included in sets of candidate numerologies pre-associated with two different carriers. This reduces the amount of numerologies that need to be supported by the corresponding user equipments (UEs) and base stations, which in turn reduces the complexity of those devices, e.g., less complex hardware, protocol stacks, and software, lower storage and processing requirements, etc. The common numerology specifies a common subset of physical layer parameters for both carriers. In one example, the common numerology specifies the same sub-carrier frequency spacing and symbol duration for both carriers. The common numerology may further specify the same cyclic prefix (CP) length for symbols communicated over both carriers.
摘要翻译：通过为网络中的至少一些载波定义重叠的候选命理集合，可以减少与动态载波配置相关联的实现复杂度。常见的命理学被包括在与两个不同载体预先关联的候选命理集中。这减少了相应的用户设备（UE）和基站需要支持的数字学的数量，这又降低了这些设备的复杂度，例如较不复杂的硬件，协议栈和软件，较低的存储和处理要求等等。常见的数字学指定两个载波的物理层参数的公共子集。在一个示例中，通用数字学指定两个载波的相同的子载波频率间隔和符号持续时间。通用命理可以进一步指定通过两个载波传送的符号的相同循环前缀（CP）长度。
