Abstract: Embodiments of the present disclosure provide a method for a transmission of uplink control information (UCI), such as hybrid automatic repeat request (HARQ) information. A base station sends first indication information to a user equipment (UE), to instruct the UE to dynamically determine the UCI according to the first indication information, and the base station allocates a physical uplink control channel (PUCCH) resource to the UE to transmit the UCI. The embodiments of the present disclosure may be used to implement a feedback of the UCI information in a carrier aggregation scenario, thereby improving performance of transmitting valid UCI information.

Abstract: Embodiments of the present invention provide a method for transmitting uplink control information and an apparatus, applicable to a multi-carrier system. A user terminal receives physical layer signaling from a network device, where the physical layer signaling includes first indication information. The user terminal determines, according to the first indication information, a bit quantity of periodic CSI that can be sent on a channel resource or a piece quantity of periodic CSI that can be sent on a channel resource. The user terminal determines, according to the bit quantity or the piece quantity of the periodic CSI that can be sent, to-be-sent periodic CSI from periodic CSI corresponding to multiple downlink carriers. The user terminal sends HARQ-ACK information and the to-be-sent periodic CSI on the channel resource.

Abstract: The present invention discloses a downlink control information sending method and device, and a downlink control information receiving method and device. The sending method includes: sending, by a base station device, downlink control information DCI on a physical downlink control channel PDCCH of a downlink subframe, where the DCI is used to instruct user equipment UE to receive physical downlink shared channel PDSCH information in an uplink subframe; and sending the PDSCH information in the uplink subframe. In this way, the base station can effectively schedule an uplink subframe, and a purpose of transmitting a downlink service by using an uplink subframe is achieved, which not only improves utilization of a wireless spectrum resource corresponding to the uplink subframe, but also effectively diverts load pressure of a wireless spectrum resource corresponding to a downlink subframe. Therefore, overall utilization of wireless spectrum resources of a system is improved.

Abstract: This application provides a method for sending uplink information in a wireless communication system that supports various services such as ultra-reliable and low latency communications (URLLC). A terminal device receives a timing advance coefficient from a network device. The terminal device determines value of a first timing advance based on a first time length and the timing advance coefficient. The first time length is one of at least two different time lengths that are supported by the terminal device. The terminal device sends the uplink information to the network device based on the first timing advance. With this method, the terminal device can uses different timing advances in different scenarios, so that diversified requirements of the fifth generation (5G) mobile communication systems for uplink synchronization are satisfied.

Abstract: A system and method for multiplexing traffic. A wireless device such as a user equipment (UE) may receive a first signal over first resources assigned to carry a first downlink transmission from a base station, and receive a first downlink control indication (DCI) message from the base station. The first DCI message may include a pre-emption region (PR) indication and a PR bitmap, and the PR indication may indicate a location of a time-frequency region. The PR bitmap may include bits associated with different portions of the time-frequency region, and each of the bits in the PR bitmap may indicate whether a preemptive downlink transmission is present in the corresponding portion of the time-frequency region.

Abstract: This application discloses a method for a hybrid automatic repeat request (HARQ) feedback of downlink data. A terminal receives downlink data of a physical downlink shared channel (PDSCH) and downlink data of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH) from a base station. Then the terminal sends a hybrid automatic repeat request (HARQ) feedback codebook to the base station. A size of the HARQ feedback codebook is based on a state of a semi-persistent scheduling (SPS) PDSCH transmission and a total downlink assignment indicator in the downlink data of the PDCCH or the EPDCCH, and the HARQ feedback codebook comprises a HARQ bit for the SPS PDSCH transmission.

Abstract: Embodiments of the present invention provide a method, where a UE determines that uplink control information to be sent to an eNB in an uplink subframe includes channel state information (CSI) and a scheduling request (SR). The UE further determines a first uplink channel resource for sending the CSI and the SR to the eNB. The first uplink channel resource has an SR sending format and is used to send the CSI. The UE then sends the CSI and the SR to the eNB on the first uplink channel resource in the uplink subframe.
