  • Publication number: 20120250599
    Abstract: A new RRC Connected (mobility) state in which a UE utilizes a temporary identifier to monitor a downlink control channel in accordance with a discontinuous reception cycle; and maintains the new connected state, the discontinuous reception cycle and the temporary identifier while the UE re-selects to a second/serving access node which lies within a same designated reselection area as a first/source access node. The DRX cycle is maintained but re-aligned with a system frame number of the second access node; the temporary identifier is a CRNTI and the designated re-selection area is defined by all contiguous cells in which respective access nodes broadcast the CRNTI in system information; the UE re-selects to the second access node; and the UE enters the new connected mobility state automatically upon expiry of a time alignment timer or upon explicit network signaling while in a different connected state.

  • Publication number: 20120243489
    Abstract: A new protocol data unit is used in communications in a radio access network. When a user equipment requests a radio resource controller connection, the UE includes its identity in the request message. In establishing the connection to UE, a serving radio network controller allocates a logical channel to the UE for communications and identifies the logical channel in the header of the protocol data unit so as to allow a receiver of the PDU to know the UE identity in an out-of-band signaling fashion, depending upon a state of the transmitter of the PDU. When the transmitter changes its state, the receiver can change state accordingly. The new PDU structure allows continuous reception of the HS-DSCH downlink channel during state transition form CELL_FACH or CELL_PCH or URA_PCH to CELL_DCH and vice versa. This new PDU structure also allows continuous HS_DSCH retransmissions.

In various specific embodiments, the DRX cycle is maintained but re-aligned with a system frame number of the second access node; the temporary identifier is a CRNTI and the designated re-selection area is defined by all contiguous cells in which respective access nodes broadcast the CRNTI in system information; the UE re-selects to the second access node in the absence of control signaling; and the UE enters the new connected mobility state automatically upon expiry of a time alignment timer or upon explicit network signaling while in a different connected state.

  • Patent number: 8233431
    Abstract: A method for minimizing the loss of data and ensuring that large delays do not occur during reconfigurations of an uplink transmission time interval (TTI) length of a WCDMA High Speed Packet Uplink Access (HSUPA) air interface, wherein the reconfiguration of an uplink TTI length is delayed until all pending retransmissions are successfully transmitted or until the maximum number of transmissions is reached. The transmission of new packets during this time period is prevented. However, pending retransmissions are allowed to occur. After the UE has received an ACK/NACK for each HARQ process, or until the specific maximum number of re-transmissions is reached, the UE starts transmitting with a new uplink TTI length.

  • Publication number: 20100323703
    Abstract: When a Universal Terrestrial Radio Access Network (UTRAN) receives an indication on Layer 3 (L3) (an L1/L2 indication is also possible) from the User Equipment (UE) that it is switching the High Speed-Data Shared Channel (HS-DSCH) reception to another cell in the active set (AS), the UTRAN sends a reconfiguration message to the UE via the target cell using a pre-configured configuration that UE has taken into use. The message can only include an indication that the pre-defined configuration can be used further by the UE or that a complete new configuration is to be used, e.g., using new HARQ info or even a hard handover (HHO) to another frequency. After receiving the configuration message, the UE responds with a normal reconfiguration complete message.

  • Publication number: 20100296464
    Abstract: A method of an uplink transfer at the UE side in a wireless communications system over a wireless interface between a radio network and a user equipment node uses a first mode of transfer and a second mode of transfer. The first mode of transfer involves sending a first message by the UE to a Node B of the wireless communication system. The second mode of transfer involves receiving a resource by the UE from the Node B, and sending at least one subsequent message by the UE to the Node B, the at least one subsequent message omits an UE id.

  • Publication number: 20090092077
    Abstract: The definition and use of an additional timer for the MAC-hs reordering function in a user equipment. The timer counts transmission time intervals and is reset each time that the user equipment receives a data packet. If the timer reaches a set value, indicating a sufficiently long period of inactivity, then the transmission sequence number is reset to zero or another predefined value. A base station can run a similar timer and, after the timer reaches a set value, can consider the user equipment as no longer being active.
