  • Patent number: 10033498
    Abstract: A method for transmitting a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH), by a user equipment (UE), in a wireless communication system. The UE generates first, second, and third DMRS sequences, which are associated with first, second, and third layers respectively, by applying first, second, and third cyclic shifts to the first, second, and third DMRS sequences respectively. The UE transmits the first, second, and third DMRS sequences to a base station, wherein the first, second, and third cyclic shifts are determined based on first, second, and third cyclic shift values respectively. The first and second cyclic shift values are separated from each other by a maximum separation value, which is determined based on a total number of cyclic shifts. The third cyclic shift value is determined by increasing cyclically by a median separation value between the first and second cyclic shift values.

  • Patent number: 10021589
    Abstract: A communication system controls Quality-of-Service (QoS) using Internet Protocol (IP) address ports. A network controller identifies an IP port range and a QoS level for a user application. The network controller transfers port/QoS data that indicates the IP port range and the QoS level for the user application. A wireless relay and a network gateway receive the port/QoS data. The wireless relay wirelessly exchanges user data with User Equipment (UE) using an IP port in the IP port range. The wireless relay exchanges the user data with the network gateway using the QoS level associated with the IP port range responsive to the use of the IP port by the UE. The network gateway exchanges the user data using the QoS level associated with the IP port range responsive to the use of the IP port by the UE.
