  • Patent number: 9516692
    Abstract: A first one of a wireless communication device (22) and a base station (20) performs a method for applying a change to a configuration or state of a radio bearer. The radio bearer supports the transfer of data over a radio connection between the wireless communication device (22) and the base station (20) with defined data transfer characteristics. The method includes performing a handshake with a second one of the wireless communication device (22) and the base station (20) to agree on a time to synchronously apply the change at the wireless communication device (22) and the base station (20). The method also includes, in accordance with the agreement, synchronously applying the change at that time.

  • Publication number: 20160295556
    Abstract: In an aspect, a wireless terminal, operating in a wireless communication system with distinct areas that each include base stations, transmits a data packet to a network node on a common channel. The data packet includes a header with an identifier that is an area-specific identifier for the wireless terminal. The wireless terminal has been allocated an area-specific identifier but not a cell-specific identifier. A network node of the wireless communication system receives the data packet sent from the wireless terminal. The network node associates the area-specific identifier for the wireless terminal in the data packet with a network-wide identifier for the wireless terminal and handles the data packet according to the network-wide identifier.

  • Publication number: 20150358921
    Abstract: The present application discloses methods and apparatus for modifying a normal link adaptation process of a wireless device (200). The normal link adaptation process may be used to compensate for a fast fading dip detected by a base station (100). The present application teaches that the normal fast fading compensation may cause inter-cell interference and degrade system performance. The present application discloses imposing a fast fading restriction or limitation on the normal fast fading compensation can reduce inter-cell interference, improve system capacity, and extends the battery life of the wireless device.

  • Publication number: 20150326374
    Abstract: Techniques for supporting concurrent deployment of 2-millisecond and 10-millisecond TTI for E-DCH transmissions in CELL_FACH state and Idle Mode are disclosed. One example method comprises receiving a transport block from a mobile terminal, wherein said transport block is transmitted using either a 10-millisecond or 2-millisecond TTI, and sending, to an RNC, an indication of whether data carried by the transport block was transmitted using the 10-millisecond TTI or the 2-millisecond TTI. In some embodiments, the indication is sent in a user plane frame sent over a base-station-to-RNC interface. A spare bit in an uplink data frame sent to the RNC may be used, for example.

  • Publication number: 20150295693
    Abstract: A wireless device (105) for managing reporting of channel quality is configured to communicate with a mobile radio communication network (102). The wireless device (105) identifies (404) there being no downlink activity between the wireless device (105) and the mobile radio communication network (102). The wireless device (105) reduces (406), in response to the identification, a level of channel quality reporting when there is no downlink activity. In a multi Radio Access Bearer (RAB) scenario this supports reduction of a higher drop rate of multi-RAB, e.g. speech and data, compared to e.g. stand-alone speech RAB.

  • Patent number: 9055452
    Abstract: Embodiments herein relate to a method in a network node (12,14) for signalling Hybrid Automatic Repeat Request, HARQ, configuration for a common enhanced dedicated channel configuration in a radio communications network (1). The network node (12,14) is comprised in the radio communications network (1) and serves a user equipment (10). The network node (12,14) determines a state of a HARQ process of a transmission time interval out of a number of HARQ processes for a common enhanced dedicated channel configuration. The state is defining whether the HARQ process is active or inactive. The network node (12,14) signals the HARQ configuration for the common enhanced dedicated channel configuration by broadcasting a value representing the state of the HARQ process.

  • Publication number: 20150139183
    Abstract: Mechanisms are provided for several aspects of network communications relating to a UE reporting cell reselection. These include how the network configures or indicates to the UE that it should report cell reselection to the network; how the UE indicates a cell reselection to the network; and how the RNC indicates to the Node-B that the UE is in need of cell reselection. Implementation of these mechanisms avoids the problems of a UE reselecting a cell and leaving voluminous data at the source cell, which may become lost, and a UE having common E-DCH resources being unable to reselect another cell, even when it leaves a serving cell's operating area.
