Abstract: Different carriers and/or bandwidth parts (BWPs) may sometimes be utilized for wireless communication between two devices. In some prior wireless communication systems, e.g. in new radio (NR), the carrier used to transmit hybrid automatic repeat request (HARQ) feedback is semi-statically configured. However, semi-static configuration might be disadvantageous, e.g. for scenarios in which latency is a concern. In some embodiments, the carrier and/or BWP for transmitting HARQ feedback is instead dynamically indicated. More generally, when two devices are wirelessly communicating with each other, the carrier and/or BWP to be used for transmitting control information may be dynamically indicated.

Abstract: A reference sequence may be transmitted in wireless communication, e.g. in order to perform channel estimation. The use of a reference sequence introduces overhead. In some embodiments, the subcarrier spacing (SCS) of the multi-carrier symbols (e.g. OFDM symbols) used to transmit one or more reference sequences is different from the SCS of the multi-carrier symbols used to transmit information (e.g. data). In some embodiments, an original reference sequence may be spread over multiple multi-carrier symbols, with each multi-carrier symbol carrying a respective reference sequence that is a portion of the original reference sequence. The technical benefit is possibly improved channel estimation because the original reference sequence is spread in time, but with the same overhead (in terms of total occupied time of reference symbols) as transmitting all of the original reference sequence at the same time.

Abstract: This application discloses a method for sending a physical uplink shared channel and an apparatus and relates to the communication field, to resolve a problem of how to transmit uplink data to different TRPs by using different precoding matrices. A network device sends indication information to a terminal device, where the indication information is used to indicate first information and second information. The first information is used to indicate first precoding information corresponding to a first nominal PUSCH repetition. The second information is used to indicate second precoding information corresponding to a second nominal PUSCH repetition. The terminal device sends N PUSCHs based on precoding information indicated by the indication information. The precoding information corresponding to the N PUSCHs includes at least one of the first precoding information and the second precoding information.

Abstract: This application provides a data transmission method and apparatus. A terminal device sends first data to a network device in the nth time unit, where n is an integer greater than or equal to 0. The terminal device send second data to the network device when the terminal device does not receive the response message corresponding to the first data before the (n+k)th time unit, wherein the second data is new data which is different from the first data, where k is a positive integer. According to the data transmission method provided in some embodiments of this application, the terminal device may flexibly determine the transmission mode of the second data based on an actual situation, so as to reduce a transmission delay of uplink data and improve transmission reliability of the uplink data.

Abstract: When a UE is in a power saving state, and the network has downlink data to send to the UE, a paging message may be transmitted in the downlink. Paging may have high overhead when beamforming is implemented. In some embodiments, a UE-specific notification is instead transmitted in a downlink beam pointed in the direction of the UE. The UE-specific notification may be a paging message specific to the UE that indicates that there is downlink data for transmission to that UE. However, more generally the UE-specific notification may be any type of downlink notification for a UE. The notification may include downlink beam information.

Then the network device sends the data channel to the terminal device, or the network device receives the data channel from the terminal device.

Abstract: By defining more SCS options and Discrete Fourier Transform (“DFT”) options for transmissions in future networks, there arises cause to select from among the options, with aspects of the channel as guidance for the selection. In addition, new CP designs may be defined for use with the new SCS options and the new DFT options along with methods of selecting a CP design appropriate to a particular situation. The new CP designs may be shown to have smaller CP overhead when compared to the known CP designs used for known combinations of an SCS option with an FFT size option. New sampling frequency design options and new system basic timing options may also be defined, along with methods of making appropriate selections from among these options. Control signaling using higher layers may be used to distribute configuration options that include multiple SCS options, CP duration options, sampling frequency options and DFT size options per sub-band.

Abstract: The present disclosure relates to a terminal device, in which a processing module selects one or more normal carriers or special carriers from a first carrier set for an uplink subframe, where the first carrier set includes all carriers in carrier aggregation that are used by the terminal device to send a first uplink subframe; and a sending module cancels sending of the uplink subframe on one or more carriers, where the special carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink, and the normal carrier is a carrier that is used by the terminal device to send uplink data and/or uplink control information. An uplink subframe on some carriers is rejected, thereby resolving a problem that information such as a downlink channel characteristic of a carrier cannot be obtained when no uplink reference signal is sent on the carrier.
