Abstract: A mobile communications system is proposed in which mobile communications devices are arranged to transmit signals to and to receive signals from a base station using one or a subset of available sub-bands, with the base station being configured to move the mobile communications devices between the sub-bands. An anchor sub-band is also provided on which idle mobile communications devices camp until they are moved to one or more other sub-bands in addition to or instead of the anchor sub-band.

Abstract: Example communication methods and apparatus are described. One example method includes receiving a first message by a terminal device from an access network device, where the first message indicates the terminal device to be handed over to a target cell or to be redirected to a target frequency. If the handover to the target cell fails or the redirection to the target frequency fails, the terminal device searches for an acceptable cell or a suitable cell. According to some embodiments of this application, an emergency call delay can be reduced.

Abstract: A gNB establishes a list of PUCCH sSCells for PUCCH sSCell switching by receiving UE capability information from a UE during an initial registration procedure, the UE capability information indicating whether the UE supports PUCCH cell switching; determining whether the UE supports PUCCH cell switching; and transmitting an RRC configuration including a PhysicalCellGroupConfig information element, the PhysicalCellGroupConfig information element including a sequence of pucch-sSCell information elements to configure multiple cells as PUCCH sSCells. The gNB may then activate, deactivate, or switch the PUCCH sSCell by sending a MAC CE. The UE is configured to use the PUCCH sSCell or the RRC configured PUUCH cell either semi-statically or dynamically.

Abstract: An antenna system having an antenna array including at least first and second phased array antennas, and a method for field-calibrating the antenna array. Before and after a handover period, communication with respective first and second external satellites or other communication systems is performed using both the first and second antennas. A first beam is formed prior to the handover period. During a first portion of the handover period: a second beam is formed for the communication with the first satellite using the first antenna; the second antenna is deactivated for external communication; and the second antenna is calibrated. During a second portion of the handover period, the second antenna is reactivated for a handed over communication with the second satellite by forming a third beam using the second antenna, while the first antenna maintains its communication with the first satellite via the second beam.

Abstract: The disclosed technology is directed towards avoiding a misconfiguration that uses a Long Term Evolution (LTE) and new radio dynamic spectrum sharing (DSS) carrier as an LTE carrier and new radio primary secondary cell carrier concurrently for a dual connectivity mobile device. Network equipment can detect the misconfiguration and prevent its usage, or if already configured, deconfigure the LTE DSS secondary cell during setup of a dual connectivity mobile device. Alternatively a dual connectivity mobile device can detect the misconfiguration and notify the network to terminate one of the carriers. Information regarding the misconfiguration can be saved in the mobile device to proactively avoid the dual misconfiguration going forward. Such information can be communicated to other mobile devices, as well as the network.

Abstract: A method, by a terminal, of performing a random access in a wireless communication system is provided. The method includes identifying a random access occasion configured for an active uplink (UL) bandwidth part (BWP) of a serving cell and when the serving cell is a special cell (SpCell) and an identity (ID) of an active downlink (DL) BWP does not correspond to an ID of the active UL BWP, switching the active DL BWP to a DL BWP with ID corresponding to the ID of the active UL BWP, based on BWP configuration information for the serving cell, and performing a random access on the switched DL BWP.
