Embodiment I
[0079]Hereinafter, preferred embodiments of the present disclosure are described below with reference to the accompanying drawings. Detailed descriptions of well-known functions and structures incorporated herein may be omitted to avoid obscuring the subject matter of the present disclosure. Certain terms may be defined to best describe this disclosure. Therefore, the meanings of specific terms or words used in this specification should not be limited to literal or commonly adopted meanings, but should be interpreted according to the spirit of the present disclosure. In the following description, the ENB is the main agent for allocating resources to the UE, and may be one of eNode B (ENB), Node B, BS, wireless access point, ENB controller, network node, etc. A terminal may be one of a communication enabled UE, a mobile station (MS), a cellular phone, a smart phone, a computer, a multimedia system, and the like. A downlink (DL) indicates a wireless link through which an ENB t...
Embodiment I-1
[0107] Embodiment I-1 proposes a solution to maintain the reception performance of UCI or PUSCH when UE sends UCI (including HARQ ACK / NACK information or RI information) to ENB in the form of multiplexing with PUSCH.
[0108] refer to Figure 5 A description is given of the main points of Example I-1.
[0109] Figure 5 A method for multiplexing HARQ ACK / NACK and PUSCH by a UE according to Embodiment I-1 of the present disclosure is shown.
[0110] refer to Figure 5 , elements 510, 520, 530, 540, 550, 560, 570, and 580 are equivalent to Figure 4 elements 410, 420, 430, 440, 450, 460, 470, and 480. In Example I-1, compared to Figure 4 In the existing scheme described in , in order to obtain additional resources for transmission, regarding UCI multiplexed with PUCSH, SC-FDMA symbol 0, SC-FDMA symbol 6, SC-FDMA symbol 7, and SC - FDMA symbol 13 (590). For example, in Figure 5 , the UE can map HARQ ACK / NACK information not only to SC-FDMA symbol 2, SC-FDMA symbol 4, ...
Embodiment I-2
[0118] Embodiment 1-2 proposes a scheme for adjusting PUSCH TBS to maintain UCI or PUSCH reception performance when UE sends UCI (including HARQ ACK / NACK information or RI information) to ENB in the form of multiplexing with PUSCH. To determine the size of data to be transmitted via PUSCH (transport block size, TBS), the UE may refer to a TBS table using a TBS index (TBSindex, ITBS) and the number of RBs used for PUSCH transmission (NPRB). The UE can obtain the values of ITBS and NPRB from MCS information and RB allocation information included in the uplink scheduling information notified by the ENB, respectively. Table 2 shows a part of the TBS table.
[0119] 【Table 2】
[0120]
[0121]
[0122] A description is given of the TBS determination scheme in the LTE or LTE-A system with reference to Table 2. For example, assume that the UE knows that the PUSCH is modulated with QPSK, ITBS=9, NPRB=9 based on the uplink scheduling information received from the ENB. Refe...
