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: Embodiments of the present disclosure relate to bit reduction in resource information. According to embodiments of the present disclosure, the number of bits to indicate the resource allocation is reduced and the network device generate the control information based on an offset associated with the bit reduction. In this way, multiple transmission opportunities for the transmission of Msg3 of the random access procedure are provided without increasing the signaling overhead.

Abstract: A method may include receiving, by a user equipment from a network entity, a first downlink (DL) control signal activating semi-persistent scheduling (SPS) of a first set of downlink data transmissions, the downlink control signal indicating an applicable hybrid automatic repeat request (HARQ) feedback timing for the first set of downlink data transmissions and receiving one or more of the first set of downlink data transmissions. The user equipment may determine that an applicable HARQ feedback timing for a second set of downlink data transmission previously received with an inapplicable HARQ feedback timing has not been provided. In response to the determination, the user equipment may determine a HARQ feedback timing for the one or more of the first set of downlink data transmissions based a second DL control signal indicating an applicable HARQ feedback timing received after reception of the one or more of the first set of downlink data transmissions.
