  • Patent number: 10666346
    Abstract: Embodiments herein relate to a method performed by a wireless device (10) for managing beam-formed communication in a wireless communication network (1), wherein the wireless device (10) is configured to handle separate directional device beams at the wireless device (10). The wireless device (10) forms an active set for a first device beam out of the separate directional device beams of the wireless device by selecting one or more first network beams out of a plurality of separate directional network beams of the wireless communication network (1). The one or more first network beams are selected based on received signal strength or quality, and the active set is to be used for transmission or reception of data. The wireless device selects a first network beam in the active set as a preferred network beam for transmission or reception of data.

  • Publication number: 20200153589
    Abstract: A user equipment (910) is provided for use in a cellular network. The user equipment includes a transceiver (1010), a processor (1020), and a memory (1030). The user equipment (910 is configured to determine, for a data transmission a mapping form a demodulation reference signal (DMRS) to a PNT-RS. A DMRS resulting signal is generated from a subset of DMRS for a first resource element in a subcarrier. The DMRS resulting signal is copied from the first resource element to a second resource element assigned to the PNT-RS in the subcarrier. The data transmission is transmitted using the DMRS resulting signal and the PNT-RS.

  • Patent number: 10630428
    Abstract: Techniques are disclosed whereby a signal is transmitted from a wireless network to a wireless device, requesting automatic repeat-request, ARQ, feedback for certain indicated ARQ processes. This asynchronous approach addresses a problem with irregular ARQ feedback for dynamic time-division-duplexing, and also allows for relaxed processing-time constraints in the wireless device. An example method, in a wireless device, comprises receiving (610) from a wireless communication network, in a first transmission-time interval, a request for ARQ feedback, the request indicating one or more ARQ processes. The example method further comprises transmitting (620) to the wireless communication network, in a second transmission-time interval, ARQ feedback information for each of the one or more indicated ARQ processes.

  • Patent number: 10624087
    Abstract: A radio-network node handling a data transmission to a wireless device transmits data over a number of subframes to the wireless device, and a respective control part, associated with the data of each respective subframe, the respective control part comprising a feedback index indicating a transmission time of a feedback indication. The radio-network node receives from the wireless device the feedback indication in the feedback message common for the subframes of the data transmission according to the control parts of the transmitted subframes. The feedback indication indicates feedback for each subframe of the data transmission received and the number of NACKed subframes out of the number of subframes of the data transmission. The radio-network node receives the feedback message and then decides whether or not to retransmit any of the subframes based on the feedback indication therein.

  • Publication number: 20200112852
    Abstract: Embodiments herein relate to a method performed by a radio network node for handling transmission of data from a wireless device in a wireless communication network. The radio network node determines a delay value for a transmission of data from the wireless device based on a transmission type of data from the wireless device or a capability of the wireless device. The capability is related to a processing time for processing received data from the radio network node, or for processing data for transmission to the radio network node. The radio network node further transmits an indication, to the wireless device, which indication indicates the determined delay value.

  • Patent number: 10531399
    Abstract: Radio resources like spreading codes and transmission power are optimally allocated to various different types of radio channels supported in the cell including a specialized channel like a high-speed shared channel. One or more measurements made at the base station are provided to the radio resource manager. Such measurements include other-channel power, high speed shared channel code usage, high speed shared channel transport format usage, average active load on the high speed shared channel, empty buffer, excess power, and similar parameters that relate to a high speed shared channel. One or more of these reported measurements may then be used to access, allocate, and/or to regulate resources associated with the base station's cell.

  • Publication number: 20190387478
    Abstract: Independent power-control procedures per beam-pair link (BPL). In one embodiment, such a power-control procedure comprises: 1) an open-loop part based on the estimated DL path loss for the active and back-up (or “non-active”) BPLs in the UE and 2) a closed-loop part where the UL power-control adjustment commands are transmitted from the network and accumulated in the UE independently per active BPL. The UL transmit power is determined from the power-control procedure associated with the active BPL scheduled for transmission.

  • Patent number: 10506450
    Abstract: Uplink-only relay and donor network node and methods therein for supporting connection of a UE in a cell associated with the network node to the uplink-only relay for uplink communication. A method in the uplink-only relay involves monitoring a relation, in terms of performance, between a direct uplink communication from the UE to the network node, and a potential relayed uplink communication from the UE to the network node via the UORN. This method further comprises indicating to the network node when the relation fulfills a condition. A method in the network node involves receiving information, from the UORN, indicating a monitored UE for which a condition is fulfilled. The condition is related to a relation, in terms of performance, between a direct uplink communication from the UE to the network node, and a potential uplink communication relayed via the UORN.

  • Patent number: 10484076
    Abstract: A network node (100), a wireless terminal (102) and methods therein, for supporting beam tracking in the wireless terminal (102) when a selected network beam (Bc) and a selected terminal beam (Tc) are used. The network node (100) identifies a set of candidate network beams (B) having spatial characteristics similar to the selected network beam (Bc), and signals the candidate network beams to the wireless terminal (102). When the network node (100) transmits beam reference signals in the candidate network beams using beam sweeping, the wireless terminal (102) measures received power using different candidate terminal beams (T) and estimates received power of combinations of beam reference signal and candidate terminal beam that have not been measured, based on the measured combinations of beam reference signal and candidate terminal beam.

  • Patent number: 10469213
    Abstract: Embodiments herein relate to a method performed by a network node (110) in a wireless communications network (100) for handling Automatic Repeat reQuest, ARQ, feedback information from a wireless device (121) relating to downlink transmissions from the network node (110). The network node (110) obtains an indication of a downlink processing delay for the ARQ feedback information from the wireless device (121). Then, the network node (110) considers the ARQ feedback information relating to a downlink transmission from the wireless device (121) to be invalid when, according to the obtained indication of a downlink processing delay, the downlink transmission has not been processed by the wireless device (121). Embodiments of the network node (110) are also described.
