Abstract: This application provides a data transmission method and apparatus, to determine a TC-state used for data transmission and correctly receive downlink data, thereby improving data transmission efficiency. The method includes: receiving a first physical downlink control channel (PDCCH), where the first PDCCH is used to schedule a first physical downlink shared channel (PDSCH); receiving a downlink signal by using a first transmission configuration indicator state (TC-state); obtaining a time interval between the first PDCCH and the first PDSCH; and if the time interval is less than a preset threshold, obtaining the first PDSCH from the downlink signal.

Abstract: This application provides an information transmission method and device. The method includes: determining, by a terminal device when an uplink-downlink configuration between the terminal device and a network device is a first uplink-downlink configuration, a first resource used to transmit first information; receiving, by the terminal device, indication information from the network device, where the indication information is used to indicate that the uplink-downlink configuration is a second uplink-downlink configuration; determining, by the terminal device based on the indication information, a second resource used to transmit the first information; and transmitting, by the terminal device, the first information with the network device on the second resource.

Abstract: Signal processing complexity in fifth generation (5G) networks can be reduced by communicating wireless signals over self-contained partitions of a carrier such that the wireless transmission communicated over each self-contained partition of the carrier includes all physical control channel signaling required to decode data carried in a physical data channel of the partition. The control signaling may include resource assignment within the partition, modulation and coding scheme indication, reference signal configuration and retransmission information. In some embodiments, an anchor partition of a carrier is used to communicate initial access information for self-contained partitions of the carrier. The initial access information may include center-frequencies, bandwidths, and/or air interface configurations of the self-contained partitions. The anchor partition may also carry load indications associated with the self-contained partitions.

Abstract: It is possible to reduce the processing intensity of blind detection by configuring user equipments (UEs) to search for fewer than all possible DCI formats defined for a physical downlink control channel (PDCCH), as this reduces the number of searches performed by the corresponding UE during blind detection. The UE may select the subset of DCI formats to search for during blind detection based on various criteria, such as an air interface configuration assigned to the UE, a UE group to which the UE belongs, a transmission mode used by the UE, a re-transmission scheme assigned to the UE, a characteristic (e.g., size, location) of the UE's search space, or a combination thereof.

Abstract: It is possible to reduce the implementation complexity associated with dynamic carrier configuration by defining overlapping sets of candidate numerologies for at least some carriers in the network. A common numerology is included in sets of candidate numerologies pre-associated with two different carriers. This reduces the amount of numerologies that need to be supported by the corresponding user equipments (UEs) and base stations, which in turn reduces the complexity of those devices, e.g., less complex hardware, protocol stacks, and software, lower storage and processing requirements, etc. The common numerology specifies a common subset of physical layer parameters for both carriers. In one example, the common numerology specifies the same sub-carrier frequency spacing and symbol duration for both carriers. The common numerology may further specify the same cyclic prefix (CP) length for symbols communicated over both carriers.

Abstract: Systems and methods of performing handover for a user equipment between hyper cells are provided. Handover is done on a per service basis. In some cases, a handover of one service from a source cell to target cell is performed while continuing to use the source cell, the target cell, or another cell for another service. In some cases the handover for a user equipment is from a source cell to a target cell in respect of one of uplink and downlink communications, and the user equipment continues to use the source cell for the other of uplink and downlink communications.
