Abstract: According to an aspect, there is provided a terminal device configured to perform the following. Initially, the terminal device monitors physical downlink control channel, PDCCH, transmissions according to a first set of rules. The first set of rules comprises rules for performing monitoring over at least two beam pair links, each beam pair link corresponding to a control resource set, CORESET, with a different active transmission configuration indication, TCI, state. The terminal device receives, using a first CORESET with a first active TCI state from an access node, an indication for limiting monitoring and consequently limits monitoring of PDCCH transmissions associated with CORESETs having a TCI state other than the first active TCI state for a period of time.

Abstract: Systems, methods, apparatuses, and computer program products for blind physical broadcast channel detection for narrowband new radio. The method may include detecting at least one synchronization signal. The method may also include determining, in response to detecting the synchronization signal, whether one or more predefined conditions of a user equipment have been met. At least one candidate pattern of a physical broadcast channel may be determined when the one or more predefined conditions have been met. The physical broadcast channel may be received with the at least one candidate pattern of the physical broadcast channel. Based on a determination of whether the physical broadcast channel was correctly received, a system information block physical downlink control channel may be received with the at least one candidate pattern of the physical broadcast channel, or the at least one candidate pattern of the physical broadcast channel may be modified.

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: A method and apparatus may include receiving an uplink grant in a specific subframe of a frame and/or a physical hybrid-ARQ indicator channel transmission, for a physical-uplink-shared-channel transmission or retransmission on a special subframe. The method may also include determining that the uplink grant validates transmitting a physical-uplink-shared-channel transmission on the special subframe, or that the physical hybrid-ARQ indicator channel transmission validates transmitting a physical-uplink-shared-channel retransmission on the special subframe. The method may also include determining transmission parameters for transmitting the physical-uplink-shared-channel transmission or retransmission. The method may also include transmitting the physical-uplink-shared-channel transmission or retransmission on the special subframe.
