  • Patent number: 9893844
    Abstract: A method and apparatus may be used for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI). A transmitter and a receiver may include a plurality of H-ARQ processes. Each H-ARQ process may transmit and receive one TB per TTI. The transmitter may generate a plurality of TBs and assign each TB to a H-ARQ process. The transmitter may send control information for each TB, which may include H-ARQ information associated TBs with the TBs. The transmitter may send the TBs using the associated H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver may send feedback for each of the H-ARQ processes and associated TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter. The feedback for multiple TBs may be combined for the simultaneously transmitted H-ARQ processes, (i.e., TBs).

  • Publication number: 20180041313
    Abstract: A first allocation of physical resources for uplink transmission is received over a downlink signaling channel. Data of a logical channel is received. A first block is transmitted over the first allocated physical resources in response to receipt of the data of the logical channel. A timer is initiated in response to transmission of the first block. In response to an expiration of the timer and not receiving a second allocation of physical resources, a first type of request from a plurality of types of requests is selected and the selected first type of request for the second allocation of physical resources is transmitted over an uplink signaling channel. The second allocation of physical resources is received in response to the transmitted first type of request. A second block is transmitted in response to the second allocation of physical resources over the second allocated physical resources.

  • Publication number: 20180042005
    Abstract: A method and apparatus for uplink transmission is disclosed. A WTRU transmits a first type message to a Node-B that indicates that the WTRU has uplink buffered data to transmit and the WTRU requires uplink resources for transmission of the uplink buffered data. The WTRU receives a first uplink data scheduling message in response to the transmitted first type message. Subsequent to receiving the first uplink data scheduling message, the WTRU transmits a second type message or a third type message. The second type message includes a plurality of indications. The third type message indicates an amount of uplink buffered data and has less information than the second type message. The WTRU receives, in response to the transmitted second type message or third type message, a second uplink data scheduling message and transmits uplink data over an uplink channel based on the received second uplink data scheduling message.

  • Patent number: 9887808
    Abstract: The present invention is related to a method and apparatus for implementing space frequency block coding (SFBC) in an orthogonal frequency division multiplexing (OFDM) wireless communication system. The present invention is applicable to both a closed loop mode and an open loop mode. In the closed loop mode, power loading and eigen-beamforming are performed based on channel state information (CSI). A channel coded data stream is multiplexed into two or more data streams. Power loading is performed based on the CSI on each of the multiplexed data streams. SFBC encoding is performed on the data streams for each of the paired subcarriers. Then, eigen-beamforming is performed based on the CSI to distribute eigenbeams to multiple transmit antennas. The power loading may be performed on two or more SFBC encoding blocks or on each eigenmodes. Additionally, the power loading may be performed across subcarriers or subcarrier groups for weak eigenmodes.

  • Publication number: 20180020465
    Abstract: A method and apparatus are provided for dynamic resource allocation, scheduling and signaling for variable data real time services (RTS) in long term evolution (LTE) systems. Preferably, changes in data rate for uplink RTS traffic are reported to an evolved Node B (eNB) by a UE using layer 1, 2 or 3 signaling. The eNB dynamically allocates physical resources in response to a change in data rate by adding or removing radio blocks currently assigned to the data flow, and the eNB signals the new resource assignment to the UE. In an alternate embodiment, tables stored at the eNB and the UE describe mappings of RTS data rates to physical resources under certain channel conditions, such that the UE uses the table to locally assign physical resources according to changes in UL data rates. Additionally, a method and apparatus for high level configuration of RTS data flows is also presented.

  • Patent number: 9867228
    Abstract: In a wireless communication system including a wireless transmit/receive unit (WTRU) and at least one Node-B, a method and apparatus is used to selectively enable reception of at least one downlink (DL) enhanced uplink (EU) signaling channel established between the WTRU and the Node-B(s). During the operation of an enhanced dedicated channel (E-DCH), the WTRU monitors at least one DL EU signaling channel established between the WTRU and the Node-B(s) only when it is necessary, based on the WTRU's knowledge of at least one established standard procedure. The WTRU coordinates and consolidates DL signaling channel reception requirements of a plurality of channel allocation and/or data transmission procedures carried out by the WTRU in accordance with the established standard procedure. The WTRU determines whether to enable reception of at least one specific DL signaling channel based on the consolidated DL signaling channel reception requirements.

  • Publication number: 20180007592
    Abstract: A method and apparatus for cell update while in a Cell_FACH state are disclosed. After selecting a target cell, system information is read from the target cell including high speed downlink shared channel (HS-DSCH) common system information. A radio network temporary identity (RNTI) received in a source cell is cleared and a variable HS_DSCH_RECEPTION is set to TRUE. An HS-DSCH medium access control (MAC-hs) entity is configured based on the HS-DSCH common system information. High speed downlink packet access (HSDPA) transmission is then received in the target cell. A CELL UPDATE message is sent to notify of a cell change. The HSDPA transmission may be received using a common H-RNTI broadcast in the system information, a reserved H-RNTI as requested in a CELL UPDATE message, or a temporary identity which is a subset of a U-RNTI. The MAC-hs entity may be reset.

  • Patent number: 9860817
    Abstract: The invention performs long term evolution (LTE) tracking area updates (TAUs), and tracking area code (TAC) and public land mobile network identification (PLMN-ID) assisted optimized wireless transmit/receive unit (WTRU) cell reselection. An evolved Node-B broadcasts system information including at least one system information block (SIB) based at least in part on an enhanced universal terrestrial radio access network (E-UTRAN) parameter response message sent by an evolved packet core (EPC) network. A WTRU generates a new TAC, which represents a tracking area identification (TA-ID) of a new cell, based on the system information, and compares the new TAC to an existing TAC, which represents a TA-ID of a previous cell. The WTRU transmits to the EPC network a TAU request message including the TA-ID of the new cell. The EPC network sends either a TAU accept message or a TAU reject message to the WTRU.

  • Patent number: 9843910
    Abstract: A method and system for reporting short message (SM) capability over an IP multimedia subsystem (IMS) using a session initiation protocol (SIP) are disclosed. A short message Internet Protocol gateway (SM-IP-GW) receives a registration request via session initiation protocol (SIP). The registration request may indicate a capability of a WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS). The SM-IP-GW transmits a successful registration message to a home location register (HLR) to indicate that a WTRU has successfully registered with the SM-IP-GW. Once the HLR is informed that a WTRU is successfully registered with the SM-IP-GW, SMS messages may be received and transmitted via the IMS using SIP.
