Abstract: A method includes: receiving, at a user equipment, a first information of a first gap for a first reference signal to be measured and a second information of a second gap for a second reference signal to be measured, wherein the first gap and the second gap overlap at least partially; and, determining at least one of: a first duration of a gap length based on a union of the first gap and the second gap, and a second duration of a gap length based on a selection of the first gap or the second gap corresponding to one of the first reference signal and the second reference signal.

Abstract: A method, device and computer readable medium for performing measurements in telecommunication systems are disclosed. The method comprises: includes receiving, from a first network device, a first configuration of a first measurement object for a carrier frequency; receiving, from a second network device, a second configuration of a second measurement object for the carrier frequency; determining an absolute time difference between a first measurement timing in the first configuration and a second measurement timing in the second configuration; and in response to determining that the absolute time difference is below a predetermined threshold, performing a single measurement for the carrier frequency based on the first measurement timing in the first configuration or the second measurement timing in the second configuration.

Abstract: Various communication systems may benefit from appropriate sharing of resources amongst multiple nodes. For example, certain wireless communication systems may benefit from using a single measurement gap for master node and secondary node measurements in a multi-radio-access-technology dual connectivity scenario, or similar scenarios. A method can include determining, by a first network node, that a gap pattern is existing in a second network node. The method can also include enquiring, by the first network node to the second network node, whether the gap pattern can be used for a new measurement. The method can further include configuring, by the first network node, a user equipment to perform the new measurement in the gap pattern, based on a response from the second network node to the enquiring.

Abstract: Various communication systems may benefit from appropriate representations of communication parameters and information. For example, certain wireless communication systems may benefit from packet number representation for multicast channel block error rate reporting. A method can include determining a number of packets corresponding to a block error rate of a multicast channel. The method can also include encoding the number of packets using an encoding format that includes a plurality of granularities and at least one threshold. The method can further include transmitting the number of packets in a report.

Abstract: Methods, apparatuses, and computer software for UE reported sounding reference signal (SRS) switching capability are provided. A method may include receiving a request, from a base station, for a sounding reference signal (SRS) switching capability of a user equipment, wherein the request includes a list of possible cells to be used by the user equipment for SRS transmission; determining, at the user equipment, the SRS switching capability of the user equipment based on the list of possible cells; and transmitting, from the user equipment to the base station, an indication of the SRS switching capability of the user equipment.

Abstract: Various communication systems may benefit from insight regarding when a device is performing power saving operations. For example, wireless communication systems may benefit from secondary cell state activation and deactivation of measurement gaps. A method can include determining, by a user equipment, whether a secondary cell is in an activated state or an inactivated state. The method can also include selectively enabling or disabling measurement gaps for the user equipment based on the determined state of the secondary cell.

Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for allocating measurement resources. According to embodiments of the present disclosure, the terminal device can determine the allocations of measurement resources to the RRM measurement and the beam recovery measurement based on priorities of the RRM and beam recovery measurements. The priorities can be determined based on the needs of the terminal device. In this way, the terminal device is able to find suitable beams faster and the interruption time for date transmission is reduced.

Abstract: Systems, methods, apparatuses, and computer program products for determining UE measurement performance in communication systems, such as NR, are provided. One method may include grouping configured carriers according to synchronization signal block measurement timing configuration (SMTC) to form carrier groups, distributing measurement gaps on the configured carriers according to an intra-frequency and inter-frequency gap sharing rule, and distributing the measurement gaps available for inter-frequency measurements among inter-frequency carrier groups according to the carrier groups with non-overlapping synchronization signal block measurement timing configuration (SMTC) or the carrier groups with overlapping synchronization signal block measurement timing configuration (SMTC) to create a distribution of the measurement gaps.
