Abstract: An embodiment provides an information monitoring method, a terminal, and a network device. The method includes: allocating, by a network device, a first frequency domain resource to a terminal, where the first frequency domain resource is used as a bandwidth part of the terminal; obtaining, by the network device, a bandwidth capability of the terminal, and determining, based on the bandwidth capability and the first frequency domain resource, a second frequency domain resource allocated to the terminal, where the second frequency domain resource is used by the terminal to monitor common information; and sending, by the network device, indication information, where the indication information is used to indicate the second frequency domain resource. According to embodiments, common information and information about a terminal can be simultaneously monitored, thereby improving information monitoring efficiency.

Abstract: This application provides a data communication method, an apparatus, and a non-transitory computer readable storage medium. In one embodiment, the terminal receives a first demodulation reference signal based on a first physical resource block index, wherein the first physical resource block index is associated with a first location in frequency domain, and the first demodulation reference signal is usable for demodulating a first downlink control channel, wherein a physical downlink control channel (PDCCH) resource associated with the first downlink control channel is configured by a physical broadcast channel (PBCH); and the terminal receives a second demodulation reference signal based on a second physical resource block index, wherein the second physical resource block index is associated with a second location in frequency domain, and the second demodulation reference signal is usable for demodulating a second downlink control channel other than the first downlink control channel.

Abstract: Methods and systems are provided that support the transmission of transport blocks over carrier bundles and bandwidth part (BWP) bundles. These carrier bundles and BWP bundles include physical resources from multiple carriers, the multiple carriers being a proper subset of the carriers configured for a user equipment (UE). A base station transmits an indication to the UE identifying one or more carrier bundles and/or BWP bundles. Each carrier bundle and BWP bundle supports the transmission of a respective transport block over a given duration, and is associated with a respective hybrid automatic repeat request (HARQ) entity.

Abstract: Embodiments of the present application provide a data transmission method. The method includes: sending, by user equipment, uplink data to a base station by using an uplink user equipment relay; and receiving, by the user equipment, downlink data from the base station, or receiving, by the user equipment, downlink data from the base station by using a downlink user equipment relay. Uplink transmission and downlink transmission are separately performed in different transmission paths, so as to reduce impact of a fault of a user equipment relay on a network, and improve network reliability.

Abstract: Systems and methods are provided for configuring an alignment between various resource grids. A base station transmits alignment information between a first resource grid or a first transmission using the first resource grid, and a second resource grid and a third resource grid. The first resource grid uses a first sub-carrier spacing (SCS) from a first set of SCSs, the second resource grid uses a second SCS from a second set of SCSs, the third resource grid uses a third SCS from the second set of SCSs. The base station transmits a synchronization sequence block (SSB) using the first resource grid, and the base station transmits a first physical downlink shared channel (PDSCH) in assigned resource blocks using at least one of the second resource grid and the third resource grid. A user equipment receives the alignment information, and determines the resource grids based on the alignment information so as to be able to receive the transmitted resource blocks.

Abstract: The time-frequency resources of a particular numerology may be used to transmit OFDM symbols that have a cyclic prefix that is longer than the cyclic prefix of other OFDM symbols. This may complicate alignment across different numerologies. Time-frequency resource partitions are disclosed herein that may assist in symbol alignment and/or subframe alignment across the different numerologies.
