Abstract: A method includes determining whether a downlink beam signal is being received from a base station (502); when the downlink beam signal is being received from the base station, determining whether a measurable property of the downlink beam signal does not meet a preselected threshold (504); when the downlink beam signal is not being received from the base station or when the measurable property of the downlink beam signal does not meet the preselected threshold, transmitting a message to the base station indicating that at least one uplink beam corresponding to the downlink beam has failed (506); and receiving a reply message from the base station with information required to determine a new uplink beam (508). An alternative method includes determining whether at least one uplink beam signal is being received from a user equipment (602); determining whether a measurable property of the at least one uplink beam signal does not meet a preselected threshold, when the at least one uplink beam signal is being received from the user equipment (604); and transmitting a message to the user equipment to initiate uplink beam recovery, when at least one uplink beam signal is not being received from the user equipment or when the measurable property of the at least one uplink beam signal does not meet the preselected threshold (606).

Abstract: Various communication systems may benefit from an improved transmission of a sounding reference signal. For example, certain communication systems may benefit from an enhanced sounding reference signal transmission via antenna switching or repetition. A method, in certain embodiments, may include receiving a signaling indication at a user equipment from a network entity. The signaling indication may indicate a configuration for sounding reference signal transmission via at least one of antenna switching or repetition using a resource group. The resource group may comprise a plurality of resources that are either adjacent or have a limited time interval between at least two of the plurality of resources within the resource group. The method may also include transmitting the sounding reference signal from the user equipment to the network entity via at least one of the antenna switching or the repetition using the resource group.

Abstract: Methods, apparatus, and computer program products for a user equipment receiving CSI-RS and computing channel support information. Based on the CSI, the UE derives tap locations of channel support, depending on the observed channel and used subcarrier spacing. The deriving can additionally be done in relation to power class and window size. The UE apprises a base station of those tap locations of the channel support and also informs the base station of the strongest tap locations, which can be done in various ways comprising a bit mask. Methods, apparatus, and computer program products for a base station to send CSI-RS to a UE for computing CSI feedback. The CSI-RS resources can be for one or multiple transmit receive points. The base station receives back an indication of tap locations and a bit mask and builds information on tap locations by combining that received indication and bit mask.

Abstract: To better support beamforming in MIMO systems such as 5G, a first match is determined between a first transmit (TX) beam group of a radio network and a first receive (RX) beam group of a user equipment (UE); and also a second match is determined between a second TX beam group of the radio network and a second RX beam group of the UE. For example these matches can come from the UE's beam report with best match information. The network configures the UE with at least a first discontinuous reception (DRX) configuration associated with the first RX beam group and with a second DRX configuration associated with the second RX beam group. In this case the first and second DRX configurations are active simultaneously for the UE, and each said beam group comprises at least one antenna or antenna port.

Abstract: Various communication systems may benefit from improved signaling. For example, communication systems may benefit from sending a multi-numerology reference signal that allows a receiving user equipment to perform simultaneous beamforming training, and channel estimation or channel state information acquisition. A method may include receiving at a user equipment a multi-numerology joint reference signal (610). The reference signal may include a reference signal for data channel demodulation or channel state information acquisition, and beamforming training. The method may also include performing simultaneous beamforming training and channel estimation or channel state information acquisition based on the multi-numerology joint reference signal (620).
