  • Publication number: 20140056289
    Abstract: The present invention relates to a method and arrangement for triggering a Random Access Channel (RACH) procedure for requesting uplink resources on a random access channel to a radio base station scheduler based on a change in terminal buffer status as compared to a Buffer Status Report BSR stored in said terminal. In a first method step, the status of the present terminal buffer content, i.e. terminal buffer data, is compared with the status of said stored buffer status report BSR. A second method step involves initiating a RACH procedure for indicating a service request to said base station scheduler upon detecting a change of buffer status at said comparison. The service request includes an indicator of the status change as a trigger for said scheduler to assign uplink resources to said terminal.

  • Publication number: 20140044079
    Abstract: A procedure for synchronization of re-configuration of RRC procedures between the radio base station and the UE is achieved by associating a new configuration to be used by a UE with an additional UE identity. The UE is normally identified by a first UE identity, but is informed in a re-configuration message that the UE also has the additional UE identity. The UE is identified by the additional UE identity when the new configuration is to be activated. Hence, when the radio base station detects that the UE responds to requests, which included the additional UE identity, the radio base station can conclude that the UE has activated the new configuration.

  • Patent number: 8634397
    Abstract: A wireless telecommunications system with mobile terminals, MSs and a Base Station, BS, through which traffic to and from the MSs in a cell, is routed, so that there can be Down Link, DL, traffic from the BS of a cell to the MSs in that cell, and Up Link, UL, traffic from those MSs to the BS. At least part of the UL traffic is contention based, and DL data to an MS must be acknowledged by the MS. The method comprises letting the BS detect MSs in the cell whose DL traffic rate exceeds a certain limit, and also comprises a mechanism for allocating to said detected MSs an UL bandwidth which enables them to acknowledge DL traffic within a certain time period from its reception by the MS.

  • Patent number: 8619689
    Abstract: The present invention relates to a method and arrangement for triggering a Random Access Channel (RACH) procedure for requesting uplink resources on a random access channel to a radio base station (600) scheduler based on a change in terminal (700) buffer status as compared to a Buffer Status Report BSR stored in said terminal. In a first method step, the status of the present terminal buffer content, i.e. terminal buffer data, is compared with the status of said stored buffer status report BSR. A second method step involves initiating a RACH procedure for indicating a service request to said base station scheduler upon detecting a change of buffer status at said comparison. The service request includes an indicator of the status change as a trigger for said scheduler to assign uplink resources to said terminal.

  • Publication number: 20130235834
    Abstract: Disclosed is a method for use in a first node in a wireless access communication system. According to the method, the first node controls traffic to and from users, UEs, within a certain area in the system, a cell, and the first node is equipped with a plurality of transmit antennas. The first node can employ a variety of multi antenna transmit modes for down link transmissions, i.e. transmissions to the UEs, and the first node can carry out a so called Random Access (RA) procedure with UEs which do not have a dedicated up link resource, i.e. a resource to the eNodeB. According to the method, one and the same down link multi antenna transmit mode is used by the first node during the RA procedure.

  • Patent number: 8472337
    Abstract: The invention discloses a method (300) for a cellular system (100) with a first node (110) which controls traffic to and from users (120) in a cell (130). Traffic between the users (120) and the first node (110) comprises user resources and control resources, with uplink traffic, comprising channels sent in data frames (200). Each data frame comprises a number of resource blocks (1, 2, 3, 4), and each uplink channel is allotted an amount of resource blocks in each data frame. At least part of the traffic between the users and the first node is divided (305) into first and second groups, and a cell's usage of the first and second group is monitored (310). The amount of resource blocks which is allotted to one of the uplink channels in a cell (130) is varied (315) depending on the cell's usage of these two groups.

  • Publication number: 20130100882
    Abstract: The present disclosure relates to delay compensation during synchronization of uplink and downlink frames in a base station in a cellular communication network. In general, the base station includes a radio equipment and a radio equipment controller that together form at least part of the base station. In one embodiment, the radio equipment includes a first interface configured to receive data from the radio equipment controller and a second interface configured to send data to the radio equipment controller. During synchronization, the radio equipment receives, at the first interface of the radio equipment, a synchronization message from the radio equipment controller. The radio equipment then passes the synchronization message from the first interface of the radio equipment to the second interface of the radio equipment with a synthetic delay that is in addition to an in-equipment delay from the first interface to the second interface.

  • Publication number: 20120236725
    Abstract: A user terminal (115, 200) for a wireless communications system, equipped with at least two antennas (205, 206, 207) for the reception and/or transmission of traffic from a higher node (105). The user terminal (115, 200) is arranged to receive (210) said traffic in one or more data streams (S1, S2) i.e. with a rank of one or higher. The user terminal is arranged (215, 216, 220) to choose with which rank the higher node (105) should transmit the traffic to the user terminal (115, 200) on, and to also signal this choice to the higher node (105). The user terminal (115, 200) is arranged to base its choice of rank on the estimated received data rate at the user terminal for different transmission ranks, the estimated power consumption in the user terminal for different transmission ranks and the Signal to Noise ratio, SIR, of the channel at the UE.

  • Publication number: 20120209508
    Abstract: A method for determining a route between a current location of a wireless device and a destination location includes establishing the current location of the wireless device by providing a signal corresponding to said current location and obtaining the destination location of the wireless device. A route is calculated from the current location to the destination location, wherein the route comprises a number of spots. One or more places relating to respective one or more of the spots along the calculated route are determined, wherein the one or more places has been registered as being visited by the wireless device. An alternative route is calculated and a set of data is stored that comprises replacement to one or more of the spots with a respective received visited place related to it. The one or more spots between the current location and the replaced spots are removed.

  • Publication number: 20110292794
    Abstract: The invention relates to communication between mobile nodes and/or node arrangements in wireless communication networks. In particular, the invention relates to a method in a radio access arrangement for improving the balance between the capacity allocated to initial access for network entry and the capacity allocated to pay-loads in the radio access arrangement. The radio access arrangement is configured to operatively communicate with a plurality of mobile nodes via an air interface. First, an initial access capacity is set to a value (S2), and then a current initial access load is obtained (S3). The next step is to increase (S7) the initial access capacity provided by the radio access arrangement (212, 312) if the current initial access load exceeds a predetermined upper limit (S4).
