摘要:
Embodiments of the present disclosure provide a channel measurement method and user equipment. In one example method, a first transmission control information is received. A semi-persistent channel measurement is started when the first transmission control information meets a first preset condition, where the first preset condition includes at least one of the following conditions: the first transmission control information is associated with a radio network temporary identifier RNTI of a first preset type, and a value of a first group of information in the first transmission control information meets a first preset rule.

The present invention provides a method, a base station, and a user equipment for feeding back ACK/NACK information for carrier aggregation. The method includes: configuring a common field preset in DCI as at least one type of command field related to ACK/NACK feedback of at least two types of command fields related to ACK/NACK feedback, where the common field can be configured as the command fields related to ACK/NACK feedback; and sending the DCI to a user equipment, so that the user equipment feeds back ACK/NACK information according to the DCI. The present invention may realize backward compatibility of the ACK/NACK information feedback with an LTE system in carrier aggregation.

A method, a user equipment, and a base station for transmitting channel state information (CSI) are disclosed. First, a scheduling grant command is sent by a base station. A CSI location label is obtained according to information of a resource occupied by the scheduling grant command and information of a resource occupied by a data channel that is indicated by the scheduling grant command. CSI of a carrier corresponding to the CSI location label is sent to the base station through the data channel. The CSI location label may be obtained through the scheduling grant command and the CSI of the carrier corresponding to the CSI location label may be sent or received without changing a length of an aperiodic CSI request field.

The present disclosure provides example acknowledgement information sending and receiving methods, as well as example sending and receiving devices. , so that the receiving device synchronously feeds back a receiving status of unicast data and a receiving status of multicast data to the sending device. One example method includes receiving unicast data and multicast data sent by a sending device in a same subframe. A feedback resource is determined according to a data receiving status and a resource mapping relationship, where the data receiving status includes a receiving status of the unicast data and a receiving status of the multicast data, and where the resource mapping relationship indicates a mapping relationship between the data receiving status and the feedback resource. Acknowledgement information is then sent to the sending device by using the determined feedback resource to notify the sending device of the receiving status of the unicast data and the receiving status of the multicast data.

Embodiments of the present invention disclose a signaling processing method. The method includes: in a downlink subframe set, generating a downlink assignment index (DAI) respectively for a downlink subframe that has a physical downlink control channel (PDCCH) to be sent, where a value of the DAI is generated according to a preset rule and a sequence of carrier first and then subframe; and sending the PDCCH to the user equipment, where the PDCCH carries the DAI. According to the embodiments of the present invention, a transmission delay is shortened and transmission efficiency is improved.

In one method, a base station sends configuration notification information to a terminal, so as to notify the terminal to set at least one radio frame meet a first subframe configuration, where the first subframe configuration includes N−1 downlink subframes, one special subframe, and zero uplink subframe. In another method, third radio frame configuration information is sent to a terminal, and second dynamic subframe indication information is sent to the terminal, so that at least one fourth radio frame is set to meet a third subframe configuration, or is set to meet a fourth subframe configuration, or at least one fifth radio frame is set to meet a fourth subframe configuration, where the third subframe configuration includes zero downlink subframe, zero special subframe, and N uplink subframes, and the fourth subframe configuration includes zero downlink subframe, one special subframe, and N−1 uplink subframes.

Embodiments of the present disclosure related to a method for configuring a transmission resource, a related device, and a communication system. The method for configuring a transmission resource includes: notifying, by an access device, a user equipment of an uplink-downlink configuration change period, where the uplink-downlink configuration change period is less than a system message change period; and sending, by the access device, a first message to the user equipment, where the first message carries an uplink-downlink configuration indication corresponding to the uplink-downlink configuration change period, so that the user equipment updates, according to the uplink-downlink configuration indication, an uplink-downlink configuration used by the user equipment. The solutions according to the embodiments of the present disclosure help to improve flexibility for configuring a transmission resource and a utilization rate of a frequency spectrum resource.
摘要:
A method, a base station (BS), and a user terminal are provided for implementing uplink resource indication. The method includes carrying an uplink resource index in an uplink resource grant (UL Grant), in which an uplink resource index corresponds to at least one uplink resource in terms of indication; and sending the UL Grant. The BS includes an index carrying module and an instruction sending module. The user terminal includes an instruction receiving module, an instruction resolving module, and an execution module.
摘要:
Method and apparatus are provided to allocate a time and frequency resource of a resource request indicator (RRI) and to transmit an RRI. Codes are allocated for an RRI and other (such as non-RRI) uplink control signaling. The RRI and other uplink control signaling can be multiplexed in the same time and frequency resource, such as through multiplexing in a code division manner.
