Abstract: Determination of characteristics of a communication environment may be beneficial in many communication systems. For example, certain wireless communication systems, such as fifth generation (5G) communication systems, may benefit from appropriate mobility measurements. A method can include performing, at a user equipment, beam-specific measurements of a plurality of beams of at least one cell. The method can also include calculating a cell quality based on the beam-specific measurements.

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: 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: 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.
