  • Patent number: 11791951
    Abstract: Methods and apparatuses for transmission of k repetitions over a channel are described. Repetition formats for the transmissions include options for slot-based repetition, mini-slot based repetition, intra-slot frequency hopping, inter-slot frequency hopping, data splitting, data switching, and DMRS sharing, among others. In some examples, intra-slot frequency hopping is performed. A first repetition of the k repetitions is sent over the channel, starting from a first symbol within a first slot, and using a first set of frequency resources. A second repetition of the k repetitions is sent over the channel, following the first repetition and starting from a second symbol within the first slot, and using a second set of frequency resources.

  • Publication number: 20220116791
    Abstract: Antenna beam sweeping according to the present disclosure involves different communication devices that are within an interference range of each other transmitting beam sweeping signals using different communication resources. This allows a receiver to distinguish between beam sweeping signals that are received from different transmitters, and may facilitate antenna beam alignment in multi-connection scenarios. Beam indices could be used to identify antenna beams for antenna beam management, in control signaling between base stations and User Equipment (UE), for example. Beam tracking and other aspects of antenna beam management are also disclosed.

  • Patent number: 11297632
    Abstract: The present disclosure relates to handling latency-sensitive traffic, in Ultra-Reliable Low Latency Communication (URLLC) for example, during measurement gaps. Latency-sensitive traffic is detected at a user equipment (UE), and transmission or reception associated with the latency-sensitive traffic is performed at the UE during a time period in which a measurement gap has been configured for the UE to perform measurement of received signal strength. The transmission or reception may be performed instead of or in addition to the measurement. Other embodiments that involve shortening measuring times and shortening or avoiding switching times associated with communication resource switching, for example, are also disclosed.

  • Patent number: 11178580
    Abstract: User Equipment (UE) mobility in Ultra Dense Networks (UDNs) is based on communication signal layers, which could include respective data streams in an Orthogonal Frequency Division Multiplexing (OFDM) domain, a code domain using respective codebooks, and/or a spatial domain, for example. A UE uses candidate layer decoding parameters in applying layer-based decoding to communication signals that it received from network nodes. Layers could be allocated to UEs and transition between network nodes as UEs move between different network service areas. Layers could instead be allocated to network nodes. Layer-based decoding provides for UE mobility without requiring explicit handover processing every time a UE moves between different service areas.

  • Patent number: 11063801
    Abstract: Methods and devices for configurable sequence usage for user equipment (UE) uplink reference signaling are provided. In one provided method, a transmission reception point (TRP) in a wireless communication network receives a first UL reference signal (RS) associated with a first UL RS sequence from a first UE and receives a second UL RS associated with a second UL RS sequence from a second UE, the first and second UL RS sequences being non-orthogonal. In another provided method, A UE determines an UL RS sequence based on a UL RS sequence root, the UL RS sequence root being a UE-specific root and being independent of a cell identifier of a cell serving the UE. The UE sends an UL RS associated with the UL RS sequence, the UL RS sequence being a Zadoff-Chu sequence.

  • Patent number: 11026224
    Abstract: Devices and methods are provided for receiving a first indication and a second indication, the first indication associated with a first set of transmission parameter information for a first repetition of data received in a Physical Downlink Shared Channel (PDSCH) and the second indication associated with a second set of transmission parameter information for a second repetition of data received in the PDSCH. Each set of transmission parameter information corresponds to a Quasi-Co-Location (QCL) information for the respective repetition of data. In addition, the method involves receiving a first PDSCH repetition and a second PDSCH repetition. A channel estimate can then be performed for the first PDSCH repetition based on the QCL information for the first PDSCH repetition and a channel estimate for the second PDSCH repetition based on the QCL information for the second PDSCH repetition.

  • Patent number: 10939340
    Abstract: Methods and devices for performing role change are described. Dynamic signaling is used. Example formats for uplink and downlink signaling is also described. In some examples, an electronic device (ED) receives, via dynamic signaling, from a first serving cell, with which the ED initially has a primary connection, a role change trigger. The role change trigger causes the ED to use a connection with a second serving cell, with which the ED initially has a secondary connection, as the primary connection instead of the first serving cell.

  • Patent number: 10826745
    Abstract: Embodiments are provided for guard band utilization for synchronous and asynchronous communications in wireless networks. A user equipment (UE) or a network component transmits symbols on data bands assigned for primary communications. The data bands are separated by a guard band having smaller bandwidth than the data bands. The UE or network component further modulates symbols for secondary communications with a spectrally contained wave form, which has a smaller bandwidth than the guard band. The spectrally contained wave form is achieved with orthogonal frequency-division multiplexing (OFDM) modulation or with joint OFDM and Offset Quadrature Amplitude Modulation (OQAM) modulation. The modulated symbols for the secondary communications are transmitted within the guard band.
