Abstract: Embodiments of the present disclosure relate to time domain resource allocation for multicast broadcast service. A first device receives, from a second device, DCI comprising a TDRA field, and determines, based on at least one of an identifier for scrambling the DCI, a RRC state of the first device or a type of traffic configured for the first device, a TDRA list from a set of configurations for TDRA. Then the first device applies, based on the TDRA list, the TDRA field for reception of the traffic from the second device. In this way, a TDRA list to be used may be determined in an optimal manner, with all terminal devices receiving multicast and broadcast traffic determining common values for time domain resources where data traffic would be scheduled.

Abstract: Embodiments of the present disclosure relates to estimating downlink size for a multicast traffic. According to embodiments of the present disclosure, a first device receives downlink control information (DCI) for a multicast traffic. The first device determines field size(s) in the DCI based on one or more parameters which are associated with the field size estimation for the multicast traffic. The first device decodes the DCI based on the determined field sizes(s). In this way, the DCI can be blindly decoded correctly.

Abstract: An example embodiment includes measuring by a user equipment, at least a signal quality and angle-of-arrival of wireless signals received from a network node; determining, by the user equipment, that the received wireless signals include signals from both primary path wireless beams and/or received reflected path wireless beams, based on the signal quality and the angle of arrival of the wireless signals; ranking, by the user equipment, the received wireless signals to primary path wireless beams and/or received reflected path wireless beams, based on the signal quality; and transmitting, by the user equipment, to the network node, at least one report including indications of both the received primary wireless beams having the best overall signal quality among both the primary and reflected beams, and received reflected path wireless beams having the best signal quality among the received reflected path wireless beams.

Abstract: Methods and apparatus for multicast services are provided. In a method a resource message is received on a control channel indicating a first search space type and assistance information for the first search space type. It is determined based on the assistance information that a second search space type is to be applied for monitoring of a multicast search space. Monitoring of the multicast search space can be provided according to the second search space type.

Abstract: Apparatuses and methods are provided to enable a receiver device monitoring a control channel configured for carrying information indicating transmission types of point-to-multipoint services detect a point-to-multipoint service of interest. The device can further detect an indication of a transmission type associated with the point-to-multipoint service of interest. In response a request can be sent for a configuration enabling reception of the indicated transmission type of the point-to-multipoint service of interest on a point-to-multipoint traffic channel. In the absence of said further detecting, the device can refrain from sending the request for the configuration for reception of the transmission type of the point-to-multipoint service.

Abstract: Disclosed are methods for power control on negative acknowledgement transmission. An example method may include receiving at a terminal device from a network device, at least one parameter relating to a transmit power for transmission of a negative acknowledgement from the terminal device to the network device on a hybrid automatic repeat request process, wherein the negative acknowledgement may indicate a request for a retransmission of a packet sent from the network device to the terminal device on the hybrid automatic repeat request process, determining at least one missed negative acknowledgement, wherein the at least one missed negative acknowledgement may include at least one sent negative acknowledgement for which no corresponding retransmission from the network device has been received at the terminal device on the hybrid automatic repeat request process, calculating a negative acknowledgement miss rate based at least on the determination of the at least one missed negative acknowledgement, and adjusting the transmit power for the transmission of the negative acknowledgement based at least on the calculated negative acknowledgement miss rate and the at least one parameter. Related apparatuses and computer readable media are also disclosed.
