Example Embodiment

[0188] Embodiment 1. A method for obtaining a target transmission block when CQI / PMI information is transmitted on a physical uplink shared channel

[0189] For CQI / PMI information, the target transport block is two transport blocks with a larger modulation coding index or a larger transport block size; wherein, if any transport block is a retransmitted transport block, the retransmitted transmission The modulation and coding index and the transmission block size of the block are the modulation and coding index and the transmission block size of the most recent first transmission block.

[0190] In the first practical application of this embodiment, two transmission blocks are configured, and both transmission blocks are enabled, namely the first transmission block TB0 and the second transmission block TB1. Both of the enabled transmission blocks have data transmission. The modulation and coding index MCS0 of the first transmission block TB0 is greater than the modulation and codin...

Example Embodiment

[0192] Embodiment 2. A method for obtaining a target transmission block when CQI / PMI information is transmitted on a physical uplink shared channel

[0193] Scenario 1, the target transmission block is the transmission block with the larger modulation coding index or the larger transmission block size of the two transmission blocks; scenario 2, the target transmission block is the transmission block with the smaller modulation coding index or the smaller transmission block size of the two transmission blocks If any transmission block is a retransmitted transmission block, the modulation coding index and transmission block size of the retransmitted transmission block are the modulation coding index and transmission block size of the most recent first transmission block.

[0194] The above scenario one satisfies one or more of the following conditions:

[0195] The difference between the respective modulation and coding indexes of the two transmission blocks is greater than or equal to...

Example Embodiment

[0231] Embodiment 3. A method for obtaining a target transmission block when CQI / PMI information is transmitted on a physical uplink shared channel

[0232] In this embodiment, the information field in the DCI format X implicitly indicates the target transport block for transmitting CQI / PMI information. In this embodiment, one of the following information in DCI format X is used to indicate the target transport block for transmitting CQI / PMI information:

[0233] (1) 1-bit PUSCH frequency hopping enable flag;

[0234] (2) 1 bit in resource allocation;

[0235] (3) 1 bit in the cyclic shift of the demodulation reference signal;

[0236] (4) 1-bit triggered aperiodic uplink measurement signal;

[0237] (5) 1 bit in the precoding index indication;

[0238] (6) 1-bit transmission block to codeword stream cross mapping identification.

[0239] When the above 1-bit information is 0, it means that CQI / PMI information is transmitted in the first transport block (the first transmission block is th...

Abstract

The invention discloses a method and a system for transmitting uplink control information on a physical uplink shared channel, thereby transmitting the uplink control information on the physical uplink shared channel, wherein the method comprises the following steps: encoding the uplink control information and a transmission block which need to be transmitted on the physical uplink shared channel according to relevant information of the target transmission block and an offset factor, interweaving the control information after the encoding with data, and then sending on the physical uplink shared channel. Compared with the prior art, the technical scheme provides the method for transmitting an uplink control channel on the physical uplink shared channel.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for transmitting uplink control information on a physical uplink shared channel and a terminal, and a method for obtaining a target transmission block when transmitting channel quality indication / precoding matrix indication information on a physical uplink shared channel and a terminal, as well as a configuration method of an offset factor and a terminal. Background technique [0002] In the long-term evolution system (LTE: Long Term Evolution), the control signaling that needs to be transmitted in the uplink includes correct / error response information (ACK / NACK: Acknowledgment / Negative Acknowledgment), and information reflecting the state of the downlink physical channel (CSI: Channel State Information) in three forms: channel quality indication (CQI: Channels Quality Indication) information, precoding matrix indication (PMI: Pre-coding Matrix Indicator) an...
