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: Various communication systems may benefit from appropriate designation of communication mechanisms. For example, fifth generation communication systems may use refinement beam index beam identifier association. A method can include determining, by an access node, an association between at least one reported refinement beam index and at least one logical beam index based on reception of a refinement beam index report. The method can also include providing the association to a user equipment.

Abstract: Systems, methods, apparatuses, and computer program products for periodic uplink (UL) signals with hybrid transceiver architectures are provided. One method includes configuring, by a network node, opportunities for periodic signal transmission for user equipment based around cell-specific sweeping uplink resources. In an embodiment, the sweeping comprises a process for providing more than one opportunity for the user equipment to transmit a periodic signal based on the user equipment's location in the cell.

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: 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.

Abstract: A method, apparatus, and a computer-readable storage medium for beam refinement of a two-step random access channel (RACH) procedure are provided. In some implementations, the method may include receiving a plurality of synchronization signal blocks (SSBs), a plurality of channel state information-reference signals (CSI-RSs) associated with each of the plurality of synchronization signal blocks (SSBs), and random access channel (RACH) configuration data from a gNB. The method may further include transmitting a first message of the two-step random access channel (RACH) procedure to the gNB, the first message including a first portion and a second portion. The first portion includes a preamble associated with a selected channel state information-reference signal (CSI-RS) of the plurality of channel state information-reference signals (CSI-RSs) and the second portion includes data associated with the preamble, and the data transmitted using pre-configured or pre-allocated resources.
