Embodiment Construction

[0171] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0172] Such as figure 1 As shown, the embodiment of the present invention provides a transmission method of the physical uplink shared channel PUSCH, including:

[0173] Step 11, determine the indication information of the HARQ confirmation; wherein, the indication information of the HARQ confirmation is at least used to indicate whether there is HARQ confirmation information on the target PUSCH;

[0174] Step 12, transmit the indication information on the target PUSCH.

[0175] In the above embodiments of the present invention, the terminal can determine the content of the indication information based on whether it receives the transport block TB or code block group CBG transmitted by the base station on the physical downlink shared channel PDSCH or wh...

Abstract

The invention provides a transmission method and receiving method of a physical uplink shared channel, a terminal and a base station. The method comprises the following steps: determining indication information of hybrid automatic repeat request acknowledgement; wherein the indication information is at least used for indicating whether hybrid automatic repeat request acknowledgement information exists on the target PUSCH or not; transmitting the indication information on the target PUSCH; In the embodiment of the invention, a terminal additionally transmits hybrid automatic repeat request acknowledgement (HARQ-) on a physical uplink shared channel (PUSCH); Wherein the indication information is at least used for indicating whether hybrid automatic repeat request acknowledgement informationexists on the target PUSCH or not, so that the base station can determine whether HARQ-exists on the PUSCH or not according to the indication information transmitted on the PUSCH; According to the embodiment of the invention, the ACK information is obtained, so that the terminal and the base station can understand resources occupied by data transmission on the PUSCH consistently, the base stationcan receive the data transmitted on the PUSCH correctly, and the transmission performance is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission method, a reception method, a terminal and a base station of a physical uplink shared channel. Background technique [0002] In an LTE (Long Term Research) wireless communication system, when a terminal UE simultaneously transmits a physical shared channel (PUSCH, Physical Uplink Shared Channel) and uplink control information (UCI, Uplink Control Information) in a certain subframe, if the UE supports PUCCH ( Physical Uplink Control Channel (Physical Uplink Control Channel) and PUSCH are transmitted simultaneously, then UCI can be transmitted on PUCCH and data can be transmitted on PUSCH. If the UE does not support simultaneous transmission of PUCCH and PUSCH, UCI will be transmitted together with data on PUSCH. The UCI includes at least a hybrid automatic repeat request acknowledgment (HARQ-ACK, Hybrid Automatic Repeat reQuest ACKnowlegement), chann...
