  • Patent number: 9806862
    Abstract: A method for grouping of CS (and comb values) for DM-RS and SRS on shared time-frequency resources is described. The method includes dividing a RS space into at least a first region and a second region. The method also includes allocating, from the first region, a DM-RS sequence CS and/or a DM-RS comb for a DM-RS; and allocating, from the second region, a SRS sequence CS and/or a SRS comb for a SRS. The DM-RS and the SRS are on the same resources on an uplink shared channel (such as a PUSCH for example). The RS space comprises at least one of a CS set and a IFDM comb set. The CS set and/or the IFDM comb set of the first region is based at least in part on a number of physical resource blocks allocated to the uplink shared channel. Apparatus and computer readable media are also described.

  • Publication number: 20160043841
    Abstract: Systems, methods, apparatuses, and computer program products for a signaling arrangement for a wireless system are provided. One method includes transmitting a short control signaling (SCS) message to one or more user equipment (UE). The SCS message may comprise at least a reference signal part and an optional control signal part. The reference signal part may comprise reference signals that allow the UE to perform at least one of: cell search, synchronization, fine time/frequency tracking, radio resource management (RRM) measurements, radio link monitoring, or channel state information (CSI) reporting. In an embodiment, the control signal part may indicate at least one of: whether the cell is ON or OFF, whether each subframe in a current or upcoming set of subframes are ON or OFF, TDD uplink-downlink configuration for a current or upcoming radio frame, PLMN ID to identify to which operator's network the cell belongs to, and/or system information.

  • Patent number: 9246650
    Abstract: A symbol multiplied by a first constant amplitude zero autocorrelation code CAZAC reference signal RS is transmitted in a timeslot from a first antenna of a user equipment on a first physical uplink control channel in a manner that multiplexes with other user equipments. A symbol multiplied by a second CAZAC RS is transmitted in the timeslot from a second antenna of the user equipment on a second physical uplink control channel in a manner that multiplexes with other user equipments. The first and second CAZAC RSs are orthogonal to one another by at least one of the cyclic shifts or a cover code applied to at least one of the first and the second CAZAC RSs. The symbols may be the same or different, and may represent an ACK, a NACK, or a scheduling request indicator. These teachings extend to more than two transmit antennas.

  • Publication number: 20140329542
    Abstract: A system for determining location information for a wireless device is described. The system includes a UE, a LE and multiple LMUs. The LE sends, to the LMUs, reception instructions with characteristics of the signal transmission from the UE and each LMU receives, from the LE, the reception instructions. The UE sends a signal transmission. Each LMU receives the transmitted signal from the UE, determines locating information based at least in part of the received signal and sends the locating information to the LE. The LE receives the locating information regarding the transmitted signal and determines a location of the UE based at least in part on the received locating information. Methods, apparatus and computer readable media are also described.
