  • Patent number: 11637652
    Abstract: Methods and apparatus for encoding and decoding a downlink control channel transmission, such as but not exclusively a High Speed Signalling Control Channel, HS-SCCH, transmission, in a wireless communications network. A method in a network node for encoding a downlink control channel transmission, comprises determining that channel conditions are below a threshold level, and in response to determining that channel conditions are below the threshold level, performing at least one of: encoding one or more predetermined control information bits into the downlink control channel transmission, and encoding a reduced number of control information bits into the downlink control channel transmission by omitting one or more control information bits, wherein the one or more omitted control information bits are predetermined control information bits. The method further comprises transmitting the downlink control channel transmission to a user equipment.

  • Publication number: 20220279385
    Abstract: A technique for Quality of Experience (QoE) or Application Layer (AL) measurements at high load is described. As to one method aspect of the technique for reporting QoE measurements from a radio device (100) wirelessly connected or connectable to a radio access network, RAN (200), the method (400) comprises or initiates a step of receiving (402; 810) a stop control message (808) from or through the RAN (200) at the radio device (100), the stop control message (808) being indicative of a command for storing (404) results of the QoE or AL measurements at the radio device (100) and stopping (406) the radio device (100) from reporting (408) the stored results of the QoE or AL measurements to or through the RAN.

  • Patent number: 11356905
    Abstract: Methods and related wireless device and radio network node, which enable the handling of Quality of Experience, QoE, measurements during handover, are described. In some aspects, the wireless device may determine whether to report QoE measurements and whether to start new QoE measurements, in a cell served by a target radio network node, based, at least in part, on the presence or absence of QoE-measurement related indications in the handover command message received from the target radio network node.

  • Patent number: 11153926
    Abstract: According to one example embodiment, a method in a user equipment, UE, includes receiving a request from a radio access network for a measurement report for an application operating at a layer above a radio resource control, RRC, protocol layer. The UE generates the measurement report in response to the request and determines a current RRC connected state of the UE when the measurement report is ready to be sent. In response to determining that the current RRC connected state of the UE is not a CELL_DCH RRC state, the UE sends a cell update message to the radio access network and receives instructions from the radio access network to transition to the CELL_DCH RRC state. The UE transitions to the CELL_DCH RRC state and transmits the measurement report while the UE is in the CELL_DCH RRC state. Related user equipment nodes, radio access nodes and methods are disclosed.

  • Patent number: 10750455
    Abstract: A method in a wireless device for determining a power allocation for an uplink transmission and a wireless device configured for determining a power allocation for an uplink transmission. Wherein the power allocation is based on a remaining power for scheduled transmissions derived from a maximum transmitter power of the wireless device, less any power for non-scheduled transmissions and a reserved power for any scheduled data transmission on the second frequency derived from a filtered power of a dedicated physical control channel, DPCCH, and a power offset for an enhanced-transport format combination, E-TFC, of a transmission for the second frequency configured with the second TTI, wherein the filtered power is averaged over a number of slots having a total duration equal to the second TTI length.

  • Patent number: 10492190
    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.

  • Patent number: 10182461
    Abstract: This disclosure relates to wireless communication. In one aspect, the technology described herein concerns a method performed by, or executed in, a control node of a wireless communication network, e.g. a RNC. The method comprises generating (401) an identifier (e.g. a handshake ID), and associating (402) the identifier with one HS-SCCH order as well as one MAC Control Information. It is thus possible to establish a one-to-one mapping between the identifier and said HS-SCCH order and said MAC Control Information. Furthermore, the generated identifier and its associated HS-SCCH order as well as its associated MAC Control Information may be communicated to another node (e.g. a UE and/or a RBS) of the wireless communication network.
