During operation, an access point may determine, based at least in part on communication with the electronic device, that an electronic device is in a communication performance category. In response, the access point may provide one or more requests to one or more neighboring access points of the access point, where a given request is for an assessment of communication performance of the electronic device from a perspective of a given neighboring access point. Next, the access point may receive one or more reports associated with one or more neighboring access points with one or more assessments of the communication performance of the electronic device. When the one or more assessments indicate that superior communication performance is unavailable, the access point may provide a notification to a computer that indicates that the electronic device is in a coverage hole in a WLAN.

An information transmission method, a base station, a mobile terminal, and a computer readable storage medium are provided. The information transmission method includes transmitting, to a mobile terminal, configuration information of a target frequency point used by the mobile terminal in a random access procedure, wherein the configuration information includes time slot information corresponding to the target frequency point and/or identification information of the target frequency point.

A communication apparatus, terminal apparatus, system and method are provided for performing wireless communication. The communication apparatus supports a plurality of component carriers, wherein one of the plurality of component carriers is designated as a current primary component and at least one of the plurality of component carriers is designated as a current secondary component carrier providing at least downlink communication. The communication apparatus comprises control circuitry for controlling a component carrier testing procedure for one or more component carriers. The testing procedure comprises, for each component carrier: establishing an uplink connection from the terminal apparatus to the communication apparatus using the component carrier; and determining a quality of the uplink connection for the component carrier. The control circuitry is responsive to completion of the testing procedure to designate an updated primary component carrier on the basis of the qualities of the uplink connections determined for the component carriers.

The invention is concerned with improvements in mobile communications, and especially with improvements in bonding communications simultaneously utilising multiple mobile networks. It may be embodied in a mobile device (12a, 12b, 12c). The mobile device (12) has a plurality of mobile network interface units (22a, 22b, 22c) each of which is configurable to connect to each of a group of mobile networks (16a, 16b, 16c). The mobile device (12) comprises at least one digital processing device implementing allocation logic which allocates each mobile network unit to one of the mobile networks (16a, 16b, 16c) and causes each mobile network interface unit (22a, 22b, 22c) to be configured to connect to the network (16a, 16b, 16c) to which it is allocated. The allocation logic serves to allocate the mobile network units (22a, 22b, 22c) to the mobile networks (16a, 16b, 16c) based on operating parameters, and to re-allocate the mobile network interface units (22a, 22b, 22c) in response to changes in the operating parameters, causing the mobile network units (22a, 22b, 22c) to be re-configured such as to disconnect from one mobile network and connect to another mobile network.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to the disclosure, a terminal reduces the delay required in beam failure detection, and thus recovery can be quick from when beam failure occurs.

A terminal apparatus for communicating with a base station apparatus is provided. The terminal apparatus includes a receiver configured to receive, from the base station apparatus, a Radio Resource Control (RRC) reconfiguration message including a parameter related to first configuration, and a processing unit configured to perform configuration in accordance with the RRC reconfiguration message received. In a case that a first timer of an RRC protocol expires, a radio link failure of a source primary cell is not detected, and configuration related to Dual Active Protocol Stack (DAPS) handover is performed for the terminal apparatus, the processing unit stops all of timers configured for a Radio Link Control (RLC) entity of a Signaling Radio Bearer (SRB) in the source primary cell, resumes the SRB suspended in the source primary cell, and transmits an RRC message for notifying the base station apparatus that the DAPS handover has failed.

A UE may perform a location-based conditional handover (CHO) based on a region information and size parameter associated with a serving cell of a non-terrestrial network (NTN). In time-based CHO, the UE may perform CHO in response to expiration of a network-configured wait time. Alternatively, the UE may perform CHO by randomly selecting a wait time from a network configured time range. The selection may be randomized using a network provided seed or using a cell Radio Network Temporary Identifier (RNTI) value. In elevation-based CHO, the UE may perform CHO in response to the elevation angle of a satellite being less than a network configured threshold. When the UE is configured with multiple cells of the NTN, and the CHO criteria for two or more of the cells are satisfied, the UE may select a target cell for CHO based on network indicated prioritization of the cells.
