There is provided mechanisms for performance degradation handling between a first radio access network node that operates in a first frequency band and provides network access for subscribers of a first mobile network operator and a second radio access network node that operates in a second frequency band and provides network access for subscribers of a second mobile network operator. A method is performed by the first radio access network node. The method comprises identifying performance degradation impacting the network access for the subscribers of the first mobile network operator. The performance degradation is identified as originating from a particular direction relative the first radio access network node and as caused by the second radio access network node. The method comprises providing, towards the second radio access network node, an indication of the performance degradation. The indication specifies the particular direction and identifies the second radio access network node as causing the performance degradation.

The present disclosure provides a method and a device in a UE and a base station for wireless communication.

The first resource element set determines a first information set out of M information sets; wherein M is equal to 2; the first resource element set comprises a positive integer number of resource element(s); any information set of the M information sets comprises a positive integer number of information element(s); any information element in the M information sets is a transmission configuration indication state; any information element of the integer number of information element(s) comprises a first type index and a second type index set, a second type index set comprises one second type index or multiple second type indices. The above method helps reduce overhead for scheduling signaling.

Disclosed are techniques for receiving reference radio frequency (RF) signals for positioning estimation. In an aspect, a receiver device receives, from a transmission point, a reference RF signal on a wireless channel receives, from a positioning entity, an indication that the reference RF signal serves as a source for a quasi-collocation (QCL) type(s) for positioning reference RF signals received by the receiver device from the transmission point on the wireless channel, measures an average delay, a delay spread, or both the average delay and the delay spread of the reference RF signal based on the QCL type(s), receives, from the transmission point, a positioning reference RF signal on the wireless channel, and identifies a time of arrival (ToA) of the positioning reference RF signal based on the measured average delay, the delay spread, or both the average delay and the delay spread of the reference RF signal.

Using a modulation and coding scheme for a control channel that is more conservative than needed to fulfill the control function may waste resources. To address this issue, a variable size control channel is provided. An apparatus in such a system may be configured to determine an aggregation level of a plurality of aggregation levels associated with a control channel. Each aggregation level of the plurality of aggregation levels is associated with a number of time-frequency resources dedicated for the control channel and a particular modulation and coding scheme used for modulating and coding control information in the control channel. The apparatus is configured to receive control information in the time-frequency resources associated with the aggregation level and decode the control information received in the time-frequency resources associated with the determined aggregation level. The decoding is based on the particular modulation and coding scheme associated with the determined aggregation level.

A resource determining method, a resource indication method, and a device are provided. The resource determining method is applied to a user-side device and includes: obtaining frequency-domain resource indication information of downlink control information DCI, where the frequency domain resource indication information supports scheduling of a plurality of carriers or bandwidth parts BWPs; and determining frequency-domain scheduling resources on the plurality of carriers or BWPs according to the frequency-domain resource indication information.

Some aspects of this disclosure relate to apparatuses and methods for implementing capability signaling design for 3rd Generation Partnership Project (3GPP) release 15 (Rel-15) and/or release 16 (Rel-16) multi-input multi-output (MIMO) enhancement. For example, systems and methods are provided implementing designs for New Radio (NR) MIMO channel state information (CSI) for a small bandwidth part (BWP) and/or a small number of subbands. For example, some aspects relate to a user equipment (UE) including a transceiver configured to communicate with a base station and a processor communicatively coupled to the transceiver. The processor receives, from the base station, a CSI reporting configuration message. The processor determines, using the CSI reporting configuration message, that a number of physical resource blocks (PRBs) of a BWP associated with the CSI reporting configuration message is less than a threshold number. The processor also generates and transmits a CSI report for the BWP.

A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

In wireless communication networks using carrier aggregation including a secondary component carrier in unlicensed spectrum, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of a communication link in the unlicensed spectrum with a secondary cell. The UE detects one or more failure events based on the downlink radio link quality. When a designated set of failure events is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in the unlicensed spectrum in order to save power and resources.
