  • Publication number: 20170033751
    Abstract: A method and apparatus for use in a packet based wireless communication system for reducing automatic gain control (AGC) convergence time at a receiver are described. A radio frequency (RF) signal is received. The RF signal includes a sequence of a plurality of pre-defined power levels at a beginning of a preamble of the RF signal. Statistics for each of the plurality of pre-defined power levels at the beginning of the preamble of the RF signal are computed. An appropriate gain for a variable gain amplifier (VGA) is then computed based on the computed statistics for each of the plurality of pre-defined power levels and a-priori information related to transmission power differences between the plurality of pre-defined power levels of the sequence.

  • Publication number: 20170034812
    Abstract: A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.

  • Publication number: 20160373218
    Abstract: Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.

  • Publication number: 20160323790
    Abstract: Splitting data in a wireless communications network. Data may be split to use multiple base stations for transmission to user equipment in order to improve the bandwith if a UE is on a cell edge, or may be split by user equipment for transmission to multiple base stations in order to improve handover. Data splitting may be performed at the Packet Data Convergence Protocol layer, at the Radio Link Control layer, or at the Media Access Control layer on user equipment or on a base station. Data may instead be split in a network node, such as in a serving gateway, in order to reduce X2 interface load or delay carrier aggregation.

  • Publication number: 20160309426
    Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.

  • Publication number: 20160241314
    Abstract: A method and apparatus are disclosed for communication in a Millimeter Wave Hotspot (mmH) backhaul system which uses mesh nodes. A mmH mesh node may receive a control signal which includes a total number of available control slots. The mesh node may determine the number of iterations of a resource scheduling mechanism that can be made during the time period of all available control slots, based on the number of neighbor nodes for the mesh node. Further, the mesh node may receive control slot information, including information about traffic queues and priorities. The mesh node may then perform resource scheduling using the resource scheduling mechanism based on the currently received control slot information and control slot information received in previous iterations of resource scheduling. The mesh node may also adjust a preamble based on a time between a last packet transmission and a current packet transmission to a neighboring node.

  • Publication number: 20160234823
    Abstract: A WTRU receives a control message intended for the WTRU in a shared physical radio resource space in a transmission time interval (TTI) monitored by the WTRU. The WTRU determines whether the control message is intended for the WTRU based on WTRU identity-masked cyclic redundancy check bits. The WTRU processes the control message. The control message has radio resource assignment information and a separate indication indicating whether the control message is a type of control message associated with an uplink or a downlink transmission. The WTRU processes a downlink transmission received in assigned radio resources in the TTI on a condition that the indication indicates that the control message type is associated with a downlink transmission. The WTRU transmits an uplink transmission in assigned radio resources in a subsequent TTI on a condition that the indication indicates that the control message type is associated with an uplink transmission.

  • Publication number: 20160205688
    Abstract: A wireless transmit/receive unit (WTRU) receives radio resource assignment information over a physical downlink control channel. The WTRU determines whether the radio resource assignment information is intended for the WTRU based on WTRU identity-masked (ID-masked) cyclic redundancy check (CRC) bits. The WTRU determines whether the radio resource assignment information is for an uplink shared channel or a downlink shared channel. The WTRU utilizes the radio resource assignment information to transmit data over the uplink shared channel on a condition that the radio resource assignment information is determined to be for the uplink shared channel. The data is transmitted over the uplink shared channel a predetermined number of time slots after reception of the radio resource assignment information.
