  • Patent number: 10959206
    Abstract: In a wireless communications system that supports directional communications (e.g., a millimeter wave (mmW) system), a base station and a user equipment (UE) may utilize directional transmissions during a paging procedure. In some cases, a base station may use beam sweeping to transmit a control channel, which may contain a paging group information. For example, the base station may configure the UE or a group of UEs to monitor for the paging group information over a set of time-frequency resources. A UE that receives the paging group information may determine transmission resources to monitor for a subsequent data channel transmission based at least in part on the identified paging group information. The base station may then transmit the paging information over the indicated transmission resources.

  • Patent number: 10925013
    Abstract: Methods for enabling and disabling of muting patterns in Radio Access Network, RAN, nodes for the purpose of allowing better detection and use of reference symbols used for synchronization. An example method for facilitating over-the-air synchronization with a neighboring base station is implemented in a base station operating in a wireless communications network. The method comprises determining (1110) that a first neighbor cell of a plurality of neighbor cells is interfering with or is likely to interfere with a signal, from the second neighbor cell, that is used for synchronization. The method further comprises sending (1120), towards the first neighbor cell and in response to said determining, a request for activation of a reference signal muting pattern by the first neighbor cell.

  • Patent number: 10880145
    Abstract: Enhanced discrete Fourier transform spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) selects spreading code roll-off factors based on available spectrum resources in a wireless network and power efficiency needs of at least one wireless device. Excess spectral resources can be used to increase processing gain and reduce peak-to-average power ratio (PAPR), both of which improve a wireless device's power efficiency. Each layer can employ a portion of the DFT-s-OFDM code space in an OFDM symbol for orthogonal multiple access or non-orthogonal multiple access, allowing multiple layers to share the same OFDM symbol. Both uplink and downlink transmissions can benefit from frequency diversity and low PAPR due to DFT-s-OFDM spreading. Since DFT-s-OFDM codes are cyclic shifts of each other, a DFT-s-OFDM discrete-time signal can be synthesized from cyclic shifts of a kernel discrete-time waveform.
