Embodiments of the present disclosure relate to devices, methods, devices and computer readable storage media of resource allocation for coverage enhancement. The method comprises receiving, at a terminal device and from a network device, an indication of a resource allocation mode to perform an uplink data transmission, the resource allocation mode at least indicating resources allocated for the uplink data transmission being to be mapped on a plurality of slots, the plurality of slots comprising no symbols configured for downlink transmission; and transmitting the uplink data transmission based on the indication. In this way, the capability of coverage enhancement for the User Equipments (UEs) can be improved by scheduling the resources for the Physical Uplink Shared Channel (PUSCH) according to the approach of resource allocation of the present disclosure.

A second radio access network, RAN, node (2) to be used in a radio communication system that supports a first Radio Access Technology, RAT, and a second RAT, the second RAN node (2) being associated with the second RAT, the second RAN node (2) comprising: means for receiving (501) a radio bearer setup request indicating at least requirements for a radio bearer of the second RAT, from a first RAN node (1) associated with the first RAT; means for including in the radio resource configuration an information element explicitly or implicitly indicating at least one numerology according to the requirements indicated by the radio bearer setup request; and means for sending (502, 503) the radio resource configuration to a radio terminal (3) via the first RAN node (1), wherein the radio resource configuration explicitly or implicitly indicates at least one numerology that is included in multiple numerologies supported by the second RAT and is different from a reference numerology.

Embodiments of the present disclosure relate to methods and an apparatuses for synchronization signal (SS) transmission. In example embodiments, a method implemented in a network device is provided. According to the method, information on a plurality of SS blocks to be transmitted by the network device is determined based on at least one of a frequency range and a value of subcarrier spacing. The information at least in part indicates timing for transmitting the plurality of SS blocks The plurality of SS blocks are transmitted to at least one terminal device based on the determined information.

Many commercially deployed devices support more than one SIM cards. Support for multi-USIM is currently handled in an implementation-specific manner without any support from 3GPP specifications. With the increased complexity of 5G-capable UEs and with growing demand for multi-USIM devices in the market, it becomes important to consider system enhancements that would allow for more efficient solution involving required support to UE from 5G core and 5G-RAN.

A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) performs, with the radio terminal (3), radio resource control for the first cell (10) and the second cell (20) in order to perform the carrier aggregation. Further, the first radio station (1) transmits, to the second radio station (2), update information regarding an update to a configuration related to the radio resource control for the second cell (20). It is thus, for example, possible to prevent or reduce data transmission/reception failures which would otherwise occur while a configuration of radio parameters or the like is being changed by a radio terminal in carrier aggregation of a plurality of cells served by different radio stations.

The present disclosure relates to synchronizing a temporary identity in the UE and the network when the UE is RRC Inactive state over 3GPP access and temporary identity of the UE is changed over a Non-3GPP access in a scenario when the UE is connected to the same AMF via 3GPP and non-3GPP access.

Embodiments of the present disclosure relate to methods, devices and computer readable media for Channel State Information (CSI) transmission. In example embodiments, a method for communication includes determining a payload of channel state information for at least one transmission layer, the at least one transmission layer used for communication between a terminal device and a network device; in response to a determination that the payload exceeds a capacity of available uplink resources, discarding a portion of the channel state information, the discarded portion at least comprising an indication specific to one of the at least one transmission layer; and transmitting, to the network device, remaining portion of the channel state information.

The present disclosure provides a method and system wherein a network indicates to a UE that the UE is allowed to send SMS over NAS in a network initiated procedure in a case for SMS subscription change wherein when the UE has been registered to the 5GS after successful Registration procedure with the status that the UE cannot have the SMS over NAS service, as the UE has subscription data "SMS service is not allowed" in the UDM.
