Abstract: A method and apparatus may include receiving configuration signaling from a network node to use a resource pool. The apparatus transmits using contention-based transmission. The method also includes selecting a preamble zone combination from the resource pool. The method may also include transmitting a preamble to the network node using the selected preamble zone combination. A preamble sequence index is used to identify the user equipment.

Abstract: A method includes accessing information, and at least one of encoding or decoding the information using a parity check matrix based on a coding rate. A portion of a data part in the parity check matrix has been generated based on part or all of another matrix. Apparatus, computer programs, and computer program products are also described. The apparatus may be a wireless mobile device or a wireless network access node. A communication system may include one or more of the wireless mobile devices and one or more of the access nodes, each using a version of the method.

Abstract: A technique includes selecting, by a user device independently for each of a plurality of sounding reference signal resources, an uplink data channel power control parameter set for an uplink data channel beam pair to be used to adjust a sounding reference signal transmission power for a sounding reference signal beam pair, adjusting, by the user device for each sounding reference signal resource based on a selected uplink data channel power control parameter set, a sounding reference signal transmission power for a sounding reference signal, and transmitting, by the user device, each of a plurality of power-adjusted sounding reference signals via a corresponding sounding reference signal resource and a corresponding sounding reference signal beam pair.

Abstract: A method is provided including transmitting a reference signal on a downlink beam to a UE; receiving from the UE a reference signal sequence; determining from the received reference signal sequence at least a preferred uplink beam to pair with the downlink beam; sending downlink signaling to the UE on at least the downlink beam; and receiving uplink signaling from the UE on at least the preferred uplink beam. A further method is provided including receiving a reference signal from a network on a downlink beam; selecting at least one preferred uplink beam to match the downlink beam; selecting a reference signal sequence that corresponds to the selected at least one preferred uplink beam; transmitting the selected reference signal sequence to the network; receiving downlink signaling from the network on at least the downlink beam; and transmitting uplink signaling to the network on the at least one preferred uplink beam.
