Abstract: A terminal device determines a resource of a physical uplink control channel. The physical uplink control channel carries a first encoded bit sequence and a second encoded bit sequence, the first encoded bit sequence is corresponding to first uplink control information, and the second encoded bit sequence is corresponding to second uplink control information. The resource for the physical uplink control channel includes N orthogonal frequency division multiplexing (OFDM) symbol sets. The first encoded bit sequence is carried in an OFDM symbol included in j OFDM symbol sets, the j OFDM symbol sets are a part of or all of of the N OFDM symbol sets, where j is a positive integer less than or equal to N. The terminal device sends, on the resource for the physical uplink control channel, a signal that is generated based on the first uplink control information and the second uplink control information.

Abstract: In a handover process, a source base station can send information about a band combination to a target base station (such as a master base station). The band combination includes a band of the target base station and a band of a secondary base station. After receiving the information about the band combination, the target base station can add the secondary base station in the handover process or add the secondary base station immediately after the handover is completed.

Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

Abstract: In the information transmission method provided in this disclosure, a terminal device receives downlink control information. The downlink control information includes first information, and the first information indicates an uplink control channel resource for carrying uplink control information. The uplink control channel resource belongs to a first uplink control channel resource set, and the first uplink control channel resource set includes at least two uplink control channel resources that correspond to different quantities of symbols, or includes at least two uplink control channel resources that correspond to different quantities of resource blocks. The terminal device sends uplink control information to a network device by using the uplink control channel resource.

Abstract: Embodiments of the present invention provide a channel-state information process processing method, a network device, and a user equipment, where the channel-state information process processing method includes: after receiving a first channel-state information CSI request sent by a first network device, if CSI corresponding to multiple aperiodic CSI processes has not been reported by a user equipment, dropping CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes, where each CSI process is associated with a channel measurement resource and an interference measurement resource. A problem existing after a CoMP technology is introduced can be solved that the UE cannot implement processing of multiple CSI processes.

Abstract: A terminal device generates a first signal. The first signal includes M first sequences, a length of each first sequence of the M first sequences is Z and each first sequence is obtained based on at least one second sequence whose length is L, the second sequence is a sequence in an orthogonal sequence group, the orthogonal sequence group includes at least two second sequences whose lengths are L, and any two second sequences in the orthogonal sequence group are orthogonal. The terminal device sends the first signal. The first signal occupies M symbols in time domain, and occupies N frequency domain units in a frequency domain. Each frequency domain unit of the N frequency domain units includes K contiguous subcarriers, the first signal occupies L contiguous subcarriers in each frequency domain unit, and the M sequences are in a one-to-one correspondence to the M symbols, where Z=N·L.

Abstract: The present disclosure discloses an uplink retransmitted data sending method, apparatus, and system, and relates to the field of communications technologies. The method includes: receiving data transmitted on a same contention resource by different user equipments (UEs) that are in a same contention resource group; demodulating, based on a demodulation reference signal DMRS sequence carried in the data, the data sent by the UEs; and when demodulation of data sent by at least two UEs fails, scheduling, by using an uplink grant (UL-grant), the UEs whose data fails to be demodulated, to retransmit the data on a designated non-contention resource. This resolves a prior-art technical problem that uplink data retransmission fails, and improves uplink data retransmission efficiency.
