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.

Abstract: There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the second access node, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.

Abstract: There is provided a method, computer program, and for an apparatus for causing an apparatus for a user equipment to perform: receiving, a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, an indication of when the first timing advance value will be invalid; using the indication of when the first timing advance value will be invalid to determine that the first timing advance value is or will soon be invalid; and determining whether to autonomously initiate obtaining a second timing advance value for the target cell in dependence on the determination of whether the first timing advance value is or will soon be invalid, the second timing advance value being obtained later in time than the first timing advance value.

Abstract: This specification describes a terminal device comprising: means for establishing a radio communications link between the terminal device and a serving cell of a telecommunications network; means for executing a transfer of the radio communications link from the serving cell to a target cell of the telecommunications network; means for detecting that a timer, expiry of which causes declaration of a radio link failure with the serving cell, has reached a threshold value but has been stopped prior to expiry and prior to execution of the transfer; and means for, after successful execution of the transfer, controlling the transmission or the content of a transfer report based on the detecting.

Abstract: This disclosure presents methods and processes to allow a user equipment (UE) to map a hybrid automatic retransmission request-acknowledgement (HARQ-ACK) feedback to one or more HARQ-ACK sub-codebooks for received services. The one or more HARQ-ACK sub-codebooks can be concatenated into one HARQ-ACK codebook and then communicated to a communication node, when those services use a HARQ-ACK feedback that is scheduled for the same time instance. Various methods can be used for the concatenation order depending on the number of multicast and broadcast services (MBS) for which HARQ feedback is to be provided, and depending on whether HARQ-ACK feedback is to be sent for unicast services at the scheduled time instance. The concatenation order can utilize an increasing order or a decreasing order of the concatenation order parameters.
