The solutions of the embodiments of the present invention can be applied to the LTE-based system in which the LTE-based Rel-8 and Rel-9 are sequentially enhanced to enhance the LTE-A Rel-10/11/12/13 and the more advanced version technologies in the LTE-A system. The UE carries the UCI through the uplink data channel, so as to achieve multiplexing of uplink control information and data on the uplink data channel when no simultaneous transmission is configured.

Embodiment 1

Embodiment 1 of the present invention provides a UE. FIG. 1 is a schematic structural diagram of a UE according to Embodiment 1 of the present invention. As shown in FIG. 1 , the UE 100 may include: a mapping module 101 and a sending module 102.

The mapping module 101 is configured to map the UCI to the preset time-frequency resource of the uplink data channel, and map the uplink data to the other time-frequency resources except the resources occupied by the preset time-frequency resource and the reference signal on the uplink data channel. .

Specifically, in the LTE system, transmission resources are divided according to time and frequency. In the time domain, the largest time unit is a 10 ms radio frame, which is divided into 10 1 ms subframes, each of which is divided into two 0.5 ms slots. For the case of the addition of the normal Cyclic Prefix (NCP), one slot is composed of 7 Orthogonal Frequency Division Multiplexing (OFDM) symbols; for the Extended Cyclic Prefix (ECP) In the case of a slot, it consists of 6 OFDM symbols. In the frequency domain, every 12 subcarriers form a 180 kHz Resource Element (RE).

The smallest unit of time-frequency resources is RE, which is a subcarrier on frequency and one in time. A two-dimensional resource composed of OFDM symbol durations. A resource block (RB) is a resource block of 12 subcarriers in a slot frequency domain in the time domain. For NCP, one RB contains 84 time-frequency resource units RE, and for ECP, one RB contains 72 time-frequency resource units RE.

One RB pair contains two RBs, consisting of 12 subcarriers in frequency and one subframe in time. For NCP, one RB pair contains 168 time-frequency resource units RE, and for ECP, one RB pair contains 144 time-frequency resource units RE. The schematic diagrams given in the drawings of the present invention are 1 RB pair or N RB pairs unless otherwise specified.

Optionally, the UCI may be control information that is required to be transmitted by a Physical Uplink Control Channel (PUCCH) in the physical uplink channel. The UCI may be channel information obtained by measuring the downlink of the UE or feedback of whether the downlink reception is correct or the like. The UE maps the UCI to the preset time-frequency resource of the uplink data channel and sends the signal to the network device, so that the network device controls the downlink transmission according to the UCI to ensure downlink data transmission.

The uplink data channel may be a Physical Uplink Shared Channel (PUSCH) in the physical uplink channel. The preset time-frequency resource includes a time domain resource corresponding to at least one resource element (Resource Element, RE for short) of the uplink data channel determined by the UE according to the preset parameter.

The mapping module 101 maps the UCI to the preset time-frequency resource of the uplink data channel, and may fill the UCI into each RE of the preset time-frequency resource. The mapping module 101 may perform mapping of the UCI according to the order of each information bit in the UCI and/or the time-frequency of each RE of the preset time-frequency resource. The mapping module 101 may also adopt other manners, such as not mapping in any order, as long as the UCI is mapped to each RE of the preset time-frequency resource.

The uplink carrier can be at least one of the at least two uplink carriers of the UE. The at least two uplink carriers of the UE may include: one primary primary carrier (PCC) and at least one secondary secondary carrier (SCC).

For example, if the UE is in a carrier aggregation scenario of the LTE-A system based on the Rel-10, the number of uplink carriers of the UE may be up to 5, that is, the UE may have a maximum of 5 uplink carriers, where One uplink carrier is PCC, and the rest are SCC. In this scenario, the sending module 102 can send the UCI and the uplink data to the network device on the uplink data channel of the PCC, so as to implement simultaneous transmission of UCI and uplink data on the uplink data channel.

For example, if the UE is in a carrier aggregation scenario of the LTE-A system based on the Rel-13, the number of uplink carriers of the UE may be up to 32, that is, the UE may have a maximum of 32 uplink carriers, where One uplink carrier is a PCC, and the rest are SCCs. Alternatively, some uplink carriers are PCCs (CCs carrying PUCCHs), and the rest are SCCs. In this scenario, the sending module 102 can send the UCI and the uplink data to the network device on the uplink data channel of the PCC and/or the at least one SCC, so as to implement simultaneous transmission of UCI and uplink data on the uplink data channel. .
