Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for configuring group indices for uplink transmissions from a user equipment (UE) such that the UE may be able to determine whether to combine uplink transmissions scheduled on overlapping time resources. Specifically, the UE may combine uplink transmissions associated with a same group index for transmission in a single channel, and the UE may avoid combining uplink transmissions associated with different group indices. In some cases, the indication of a group index associated with an uplink transmission from a UE may be explicit (e.g., provided in a downlink control information (DCI) message), and, in other cases, the indication of a group index associated with an uplink transmission from a UE may be implicit (e.g., corresponding to a resource allocated for the uplink transmission).

Abstract: An embodiment method, by a user equipment (UE), includes performing a channel measurement (CM) on a first subset of a set of non-zero-power (NZP) CSI reference signal (CSI-RS) resources and an interference measurement (IM) on at least a second subset of the set of NZP CSI-RS resources. The second subset includes one or more NZP CSI-RS ports. The IM is performed according to assumptions: each NZP CSI-RS port in the second subset corresponds to an interference transmission layer, the IM being in accordance with a set of energy per resource element ratios each associated with one NZP CSI-RS resource in the second subset; and other interference not associated with the interference transmission layers is on the first and second subsets. The method includes generating a channel state information (CSI) report based on the CM and IM and transmitting the CSI report to a network.

Abstract: A control apparatus predicts a probability distribution of radio quality when a downlink transmission from a base station to a radio terminal or an uplink transmission from a radio terminal to a base station is to be performed. The control apparatus calculates an expected value of a block error rate or reliability in the downlink or uplink transmission using the predicted probability distribution. The control apparatus determines a value of each of one or more parameters related to the downlink or uplink transmission, taking into account the calculated expected value.

Abstract: A base station distributed unit (BS-DU) receives, from a base station central unit (BS-CU), at least one configuration message comprising bearer configuration parameters of at least one bearer for a wireless device, wherein the at least one bearer is configured between the wireless device and the BS-CU through the BS-DU. The BS-DU communicates, with the wireless device and via the at least one bearer, a first adaptation layer packet, wherein a first header of the first adaptation layer packet comprises a route identifier indicating a route. The BS-DU determines a failure of a link between the BS-DU and the BS-CU and transmits, to the wireless device, backhaul link information indicating the failure of the link, wherein a second header of a second adaptation layer packet comprises the backhaul link information indicating the failure of the link.

Abstract: The invention relates methods for triggering channel quality feedback for at least one of plural component carriers of a communication system available for downlink transmission. The invention suggests a mechanism for triggering channel quality feedback from a terminal where the downlink control signaling overhead for the selection of component carrier(s) to be reported on is minimized. One aspect of the invention is a new interpretation of a predetermined format for dedicated control information comprising a CQI request flag, which is depending on the status of the CQI request flag. In case the CQI request flag is set at least one further bit of the dedicated control information is interpreted as information indicative of the one or more component carriers available for downlink transmission to the terminal and the terminal is providing channel quality feedback on the channel quality experienced on the indicated component carrier or component carriers.

Abstract: A method for limiting Channel Quality Indicator (CQI) reporting from a User Equipment to a network node is provided where a User Equipment can transmit CQI reports to a network node, such as e.g. a base station, when the User Equipment is operating in low transmission and/or low reception activity mode. A limited CQI reporting is obtained by triggering the reporting according to one or more predefined rules, which to at least some extent depend on CQI specific information provided to the User Equipment from the network node. A User Equipment and a network node adapted to operate in accordance with the suggested method are also provided.
