Abstract: A radio network element includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the radio network element to: configure a quasi-co-location-type information entry included in a transmission configuration indication state (S604) for a downlink transmission beam between the radio network element and a user equipment based on at least one beam report, the at least one beam report including at least one transmission parameter for the downlink transmission beam, and the quasi-colocation-type information entry being indicative of one or more sources of inter-beam-interference on the downlink transmission beam at the user equipment; and transmit the transmission configuration indication state including the quasi-co-location-type information entry to the user equipment (S606).

Abstract: According to an aspect, there is provided a method comprising: determining, by an apparatus, that data is to be exchanged between the apparatus and another apparatus, wherein the other apparatus does not have a wired backhaul connection; obtaining, by the apparatus, a time domain resource partitioning, wherein the time domain resource partitioning comprises a plurality of portions grouped to a first group and to a second group such that a first portion of the first group is available to a first downlink transmission and a first portion of the second group is available to a second downlink transmission; detecting, by the apparatus, if a channel is available for transmission; and if the channel is available for transmission, transmitting, by the apparatus, to the other apparatus according to the time domain resource partitioning.

Abstract: The specification and drawings present methods and apparatuses for feedback signaling for beamforming purposes in a multiple input-multiple output (MIMO) radio environment. According to an embodiment of the invention, a mobile device is configured to measure an integer number P of different beam groups, each group representing one or more transmit beams and each group corresponding to one or more antenna ports at the mobile device. The mobile device is triggered according to the configuration to provide feedback. The radio access node transmits reference signals on each of the transmit beams across all of the groups for measurement by the mobile device and receives the triggered feedback including, for each of the different beam groups, at least one best match between a transmit beam of the respective group and a corresponding antenna port and an indication of measurement results for the best match.

Abstract: A technique may include determining, by a base station in a wireless network, that the base station was unable to transmit a synchronization signal block for a beam via a beam-specific synchronization signal block position that is associated with the beam; transmitting, by the base station in response to the determining, a synchronization signal block for the beam via a non-beam-specific synchronization signal block position; and transmitting, by the base station, control information indicating the transmitting of the synchronization signal block via the non-beam-specific synchronization signal block position.

Abstract: In a first subframe, data is sent by a network node in a DL shared channel and a timing indicator is sent in a PDCCH to UE, the timing indicator indicating an offset relative to the first subframe the UE should use in order to determine a second subframe to use to send, in a PUCCH, acknowledgement information for the data received in the DL shared channel of the first subframe. The acknowledgement information is received by the network node from the UE in the PUCCH of the second subframe. The UE receives the data and timing indicator and determines the second subframe using at least the timing indicator. The UE transmits the acknowledgement information in the PUCCH of the second subframe. Apparatus, computer programs and products, and methods are disclosed.
