  • Patent number: 11050483
    Abstract: A UE may determine a frame structure for narrowband communications, the frame structure corresponding to one frame structure from a group of TDD frame structures of different downlink and uplink subframe configurations. The UE receives configuration information indicating a first carrier to monitor for a BCH and/or a SIB1. Then, the UE receives a PSS, an SSS, and the BCH and/or the SIB1 using the frame structure determined for the narrowband communications. The first carrier that is used to receive the BCH and/or the SIB1 may be different from a second carrier used to receive one or more of the PSS or the SSS.

  • Patent number: 10958337
    Abstract: There is a need to support narrowband TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a narrowband communication frame structure comprising a FDD mode or a TDD mode and a particular TDD frame structure for narrowband communications from a group of narrowband TDD frame structures. The apparatus may determine a periodicity, subframe number, and transmission sequence associated with a SSS based at least in part on the narrowband TDD frame structure. The apparatus may transmit the SSS using the narrowband TDD frame structure determined for the narrowband communications. In one aspect, the SSS may be transmitted in a same subframe within a frame and at a periodicity of 2 or more frames.

  • Publication number: 20210076449
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that identifies one or more narrowband channels in which the UE is to receive one or more physical downlink shared channel (PDSCH) repetitions of a paging message associated with a discontinuous reception procedure. The UE may receive, in an online mode of the UE, one or more machine-type communication physical downlink control channel (MPDCCH) repetitions of control information. The UE may receive, in the online mode of the UE, the one or more PDSCH repetitions in the one or more narrowband channels identified by the configuration. The UE may process, in an offline mode of the UE, the one or more MPDCCH repetitions and the one or more PDSCH repetitions. Numerous other aspects are provided.

  • Patent number: 10735117
    Abstract: Techniques described herein permit a narrowband Internet of Things (NB-IoT) user equipment (UE) to combine narrowband reference signals (NRS) with other signals, which the NB-IoT UE already receives, to improve measurement accuracy. These other signals may require different modifications to be combined with the NRS depending on the type of signal. Techniques described herein provide indications of how the UE is to combine different types of signals with an NRS in order to improve measurement accuracy.

  • Patent number: 10560294
    Abstract: Techniques and apparatus for transmission and reception with partial allocation in orthogonal frequency division multiple access (OFDMA)/single-carrier frequency division multiple access (SC-FDMA) systems are provided. One technique includes determining first parameter(s) to apply to transmission/receive processing of a signal, based in part on a resource allocation for the signal. The resource allocation is partitioned out of a larger system bandwidth. Second parameter(s) to apply to the transmission/receive processing are determined based at least in part on the first parameter(s). Transmission/receive processing of the signal is performed in accordance with the first and second parameters.
