Abstract:
A method, apparatus and computer program product are therefore in order to enable efficient management of multiple communication channels. In this regard, the method, apparatus, and computer program product may utilize a user equipment (UE) (208), such as a mobile terminal, to communicate a plurality of networks. The UE (208) may identify that multiple communication networks are available or in use, and notify a network node (204, 206) associated with one of the networks of the communication status. In response to receiving a notification that UE (208) is communicating across an alternate channel, the network node (204, 206) may reconfigure the channel with which the network node (204, 206) communicates with the UE (208), or instruct the UE (208) to do the same.
Abstract:
According to an example embodiment, a method may include determining, by a first base station associated with a first cell based on a synchronization signal block (SSB) configuration indicating one or more resources on which a synchronization signal block (SSB) may be transmitted by a second cell, one or more interference protected resources on which the first cell will reduce interference towards the second cell; and sending, by the first base station associated with the first cell to a second base station associated with the second cell, information identifying the one or more interference protected resources on which the first cell will reduce interference towards the second cell.
Abstract:
Systems, methods, apparatuses, and computer program products for applying beam diversity for multi-slot physical downlink shared channel (PDSCH) are provided. One method may include receiving configuration of a multi-slot transmission mode for a multi-slot communication channel. The method may also include receiving, based on the configuration of the multi-slot transmission mode, transmission configuration indications of a plurality of transmit beams for slots in the multi-slot communication channel. A selected set of candidate transmit beams may be received among the plurality of transmit beams for the slots in the multi-slot communication channel. The method may also include determining, among the selected set of candidate transmit beams, which transmit beam is used for each slot in the multi-slot communication channel, and applying a reception beam corresponding to each transmit beam used for each slot in the multi-slot communication channel.
Abstract:
Systems, methods, apparatuses, and computer program products for physical random access channel (PRACH) in unlicensed spectrum may be provided. For example, a configuration may be provided to a user equipment, where the configuration is related to using short control signaling exemption (SCSe) in connection with the management of uplink PRACH transmissions.
Abstract:
Method, apparatus, and computer program product for a CORESET beam recovery procedure and a QCL association beam recovery procedure where a condition or rule based UE initiated change of active TCI state is used. The CORESET beam recovery procedure involves a downlink reference signal corresponding to a transmission configuration indication state activated for certain CORESET being determined as a beam failure detection resource. The QCL association beam recovery procedure concerns a UE transmitting a UL request signal to require switching an active TCI state of the CORESET to a currently deactivated TCI state of the same CORESET.
Abstract:
A method including, detecting, by a base station in a wireless communication system, within an RAR window, at least one of multiple first messages from a plurality of user equipments, wherein the plurality of user equipments is permitted to transmit multiple first messages within the RAR window, and wherein each first message includes a PRACH preamble; in response to receiving at least one PRACH preamble in the at least one of multiple first messages, transmitting at least one second message including an RAR downlink channel for each preamble received; receiving at least one third message, from at least one user equipment of the plurality of user equipments, including a beam connection request and transmitting at least one fourth message to the at least one user equipment on the requested beam.
Abstract:
Systems, methods, apparatuses, and computer program products for selecting or prioritizing between a physical downlink shared channel (PDSCH) and synchronization signal PBCH block (SSB) reception are provided. One method may include, when outside a SMTC window and when PDSCH resource allocation overlaps with an occupied SSB location, selecting between the PDSCH and SSB reception according to defined rules.

Abstract:
Methods and apparatus, including computer program products, are provided for MBSFN measurements. In one aspect there is provided a method. The method may include receiving, by a user equipment, an indication of a monitoring requirement (202, 204) for at least one of an idle mode of operation at the user equipment or a connected mode of operation at the user equipment; receiving, by the user equipment, information (206) for one or more transmissions (MBMS) that are multicast or broadcast; and measuring, by the user equipment, the one or more transmissions (MBMS) that are multicast or broadcast, the measuring performed in accordance with the received information (206) and without regard to the indication of the monitoring requirement (202, 204) for at least one of the idle mode of operation or the connected mode of operation. Related apparatus, systems, methods, and articles are also described.
Abstract:
One embodiment is directed to a method comprising generating information related to resource which can be used for allocating a data transmission; transmitting the information to a user equipment, and sending the data transmission within the resource. In some embodiments, the resource is a frequency domain resource and the information indicates whether the resource comprises a RMSI CORESET bandwidth or a RMSI CORESET bandwidth and a SS/PBCH block frequency allocation.
