Method for a User Entity, UE, being adapted to transmit uplink data according to a NR TDD scheme, with a NR bases station, gNB, the UE being further adapted to transmit HARQ-ACK information, being an ACK or a NACK for received data on a downlink channel and a Scheduling Request, SR, may be provided comprising an indication of data or no data to be pending for transmittal on the up-link. The method comprises-establishing if HARQ-ACK info is available in a slot (), —establishing if an SR-PUCCH is present in the slot (), —if no SR-PUCCH present in the slot, generating () a SR, —appending () the SR to the HARQ-ACK, —transmitting () the SR appended to the HARQ-ACK.

Aperiodic scheduling request

Method for a base station communicating with a plurality of User Entities, UE, according to a Time Division Duplex, TDD, access scheme via antennas, the base station being adapted for receiving Scheduling Requests, SRs, from the UEs, a SR indicating a request for scheduling an uplink transmission from a UE. The base station is communicating over a plurality of antennas associated with respective wide beams and narrow beams, a plurality of wide beams covering respective areas, whereby for each wide beam at least one narrow beam form a joint area with a wide beam. The TDD scheme involving at least a Physical Uplink Scheduling Control Channel, PUSCH, and including periodically appearing SR occasions, the base station being adapted for receiving and decoding a transmission from a UE and establishing whether a SR from at least one UE is received in a periodic occasion.

SR handling for analog beamforming

A network node is disclosed that communicates with a user equipment node in a communications system. The network node repetitively transmits first uplink transmission power control, TPC, commands on a first physical channel with a first channel configuration while repetitively transmitting second uplink TPC commands on a second physical channel with a second channel configuration. The first and second uplink TPC commands control uplink transmission power from the user equipment node to the network node. Related user equipment nodes and methods are disclosed.
