摘要： A receiver baseband processor (155) and method for performing preamble detection and Time-of-Arrival, ToA, estimation for a single-tone frequency hopping random access preamble. The processor FFT processes (11) a received signal and identifies logical tones. For each logical tone, the processor reads (12) received symbols; determines (13) a ToA estimate; forms (14) a statistic based on the ToA estimate; compares (15, 16) the statistic to a preamble threshold; and when the statistic is greater than or equal to the threshold, determines (17) a preamble is present and utilizes the ToA estimate for a timing advance command.

The wireless communication device (14) in particular is configured to generate a random access preamble signal (16) that comprises multiple symbol groups (18), with each symbol group (18) on a single tone during a different time resource, according to a frequency hopping pattern that hops the random access preamble signal (16) a fixed frequency distance at one or more symbol groups (18) and hops the random access preamble signal (16) a pseudo random frequency distance at one or more other symbol groups (18). Each symbol group (18) comprises one or more symbols. The wireless communication device (14) is also configured to transmit the random access preamble signal (16).

摘要： In Narrowband, NB, networks such as NB Internet of Things, IoT, transmissions of NB Physical Broadcast Channel, NPBCH from a NB base station (11) to in-band mode NB IoT UEs (31) requires the reservation of predetermined symbols and resource elements, RE, for non-interference with legacy LTE UE operation. In contrast, in stand-alone and guard-band mode deployments, transmissions to NB IoT UEs (31) may include NB IoT data in these resources. Examples include the first, e.g., three symbols of NPBCH, reserved for the LTE Physical Downlink Control Channel, PDCCH, and numerous REs reserved for LTE Cell-specific Reference Symbols, CRS. These resources may be used to transmit NB IoT data to stand-alone and guard-band mode NB IoT UEs (31), such as by repeating data from other symbols or REs. The repetition allows the stand-alone and guard-band mode NB IoT UEs (31) to perform frequency tracking or enhanced reception by energy accumulation.
摘要翻译：在窄带NB中，诸如NB物联网，IoT，NB物理广播信道的传输，从NB基站（11）到带内模式NB IoT UE（31）的传输，需要保留预定的符号和资源元素RE以便不干扰传统的LTE UE操作。相反，在独立和保护带模式部署中，到NB IoT UE（31）的传输可以在这些资源中包括NB IoT数据。示例包括为LTE物理下行链路控制信道保留的第一（例如）三个符号的NPBCH，PDCCH以及为LTE小区特定参考符号CRS保留的多个RE。这些资源可用于通过诸如通过重复来自其他码元或RE的数据来将NB IoT数据发送到独立和保护带模式NB IoT UE（31）。重复允许独立和保护带模式的NB IoT UE（31）通过能量累积来执行频率跟踪或增强的接收。

摘要： A radio network node (10) is configured to transmit a narrowband primary synchronization signal (NB-PSS) and a narrowband secondary synchronization signal (NB-SSS) within a synchronization signal period comprising multiple frames. The radio network node (10) maps the NB-PSS to the same one or more subframes within each frame in which the NB-PSS is to be transmitted. The radio network node (10) also maps the NB-SSS to the same one or more subframes within each frame in which the NB-SSS is to be transmitted, including at least one frame in which the NB-PSS is to be transmitted. The radio network node (10) does so by mapping the NB-SSS to one or more subframes that differ from the one or more subframes to which the NB-PSS is mapped. The radio network node (10) transmits the NB-PSS and NB-SSS within the synchronization signal period according to this mapping.
