Problems solved by technology

[0009] As mentioned above, the existing HARQ timing relationship is definite, generally determined by the protocol, so when a new TDD configuration is adopted, a new timing relationship needs to be generated, resulting in a relatively large workload

Embodiment 1

[0080] In this embodiment, the HARQ timing relationship between the dynamically scheduled PDSCH, the SPS PDSCH, and the PDCCH indicating SPS release is described, and the description is given below in two cases.

[0081] Case 1: For a UE, the HARQ timing relationship of the dynamically scheduled PDSCH of the UE is determined by the semi-static configuration of the high-layer signaling.

[0082] For the first case, the HARQ timing relationship between the UE's SPS PDSCH and the PDCCH indicating SPS release is the same as the HARQ timing relationship of the dynamically scheduled PDSCH, which is uniformly determined by the high-level signaling configuration. The timing relationship applies not only to the dynamically scheduled PDSCH, but also to the SPS PDSCH and the PDCCH indicating the release of the SPS, and can be specifically configured through a high-level signaling. Or, for the first case, the HARQ timing relationship of the UE's SPS PDSCH and the PDCCH indicating SPS rele...

Embodiment 2

[0107] In this embodiment, the time units (that is, k, k) in the timing relationship between the dynamic scheduling PDSCH, SPS PDSCH and PDCCH indicating SPS release and HARQ are described i and k i ' time unit), since the length of the time slot may be different in different serving cells and at different times of the same serving cell, therefore, whether to configure the HARQ timing relationship by using high-level signaling, or use physical layer signaling to dynamically indicate The HARQ timing relationship needs to determine the length of the time unit.

[0108] If the time slot length A of the serving cell that transmits HARQ-ACK is constant, and the time slot length B of the serving cell that generates the PDSCH of HARQ-ACK or the PDCCH that indicates SPS release is constant, and the HARQ-ACK is generated The time slot length B of the serving cell of the PDSCH or PDCCH indicating SPS release is the same as the time slot length A of the serving cell that transmits HARQ-...

Embodiment 3

[0114] In this embodiment, a method for transmitting UCI composed of HARQ-ACK / SR and CSI in PUCCH and PUSCH is described. The following situations are described separately.

[0115] Case 1: When the UE configures that the length of the time slot of the PUCCH for transmitting the UCI is the same as the length of the time slot of the PUSCH for transmitting the data, the following method is adopted.

[0116]When the UE is configured to transmit PUCCH and PUSCH at the same time, at least one PUSCH is to be transmitted, and when only periodic CSI is transmitted, the UE transmits periodic CSI on the PUCCH; when the UE is configured to transmit PUCCH and PUSCH at the same time, at least one When one PUSCH transmission is transmitted, and only HARQ-ACK / SR is transmitted, the UE transmits HARQ-ACK / SR on the PUCCH; when the UE is configured to transmit PUCCH and PUSCH at the same time, at least one PUSCH transmission must be transmitted, and the periodic When CSI and HARQ-ACK are trans...

Abstract

The present application discloses a method for transmitting UCI, including: the terminal determines the dynamically scheduled physical downlink shared channel PDSCH and / or the semi-persistent scheduling SPS PDSCH and / or the HARQ timing relationship of the PDCCH indicating SPS release according to the information sent by the base station; The terminal transmits the generated HARQ-ACK information according to the determined timing relationship. By applying the present application, it is possible to simplify the method for determining the timing of HARQ-ACK, and to transmit HARQ-ACK information in time.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and more particularly, to a method and device for transmitting uplink control information (UCI) of a physical downlink shared channel (PDSCH, Physical Downlink Shared Channel). Background technique [0002] The Long Term Evolution (LTE, Long Term Evolution) technology supports two duplex modes: Frequency Division Duplex (FDD, Frequency Division Duplex) and Time Division Duplex (TDD, Time Division Duplex). figure 1 It is a schematic diagram of the frame structure of the TDD system of LTE. The length of each radio frame is 10 milliseconds (ms), and it is divided into two half-frames of length 5ms. Each half-frame contains 8 time slots of length 0.5ms and 3 special fields of 1ms. The domains are downlink pilot time slot (DwPTS, Downlink pilot time slot), guard interval (GP, Guard period) and uplink pilot time slot (UpPTS, Uplink pilot time slot). Each subframe consists o...
