example 1

[0172] The base station sends configuration information to the UE, indicating that it does not support the transmission of HARQ-ACK on the grant-free PUSCH, for example, sending the configuration parameter HARQ-ACK_ON_GF through high-level signaling, which indicates "FALSE"; the UE receives the high-level signaling and determines the high-level signaling Set the sent configuration parameter HARQ-ACK_ON_GF to be "FALSE", and then determine not to send HARQ-ACK on the grant-free PUSCH.

[0173] Case 1: If Figure 4 As shown, it is assumed that the base station has scheduled 3 PDSCHs, and the HARQ-ACKs of these three PDSCHs are all fed back at the same uplink time (for example, slot n+5); assuming that this time is configured for the grant-free PUSCH time, and The UE does not support simultaneous transmission of PUCCH and PUSCH; then:

[0174] UE side:

[0175] (1) When the UE receives at least one of the three PDSCHs, the UE determines that there is HARQ-ACK transmission in th...

example 2

[0190] The base station sends configuration information to the UE, indicating that it supports the transmission of HARQ-ACK on the grant-free PUSCH, for example, sending the configuration parameter HARQ-ACK_ON_GF through high-level signaling, which indicates "TRUE"; the UE receives high-level signaling and determines the high-level signaling The sent configuration parameter HARQ-ACK_ON_GF is "TRUE", and then it is determined that the HARQ-ACK can be sent on the grant-free PUSCH. For example, for case 1 of example 1:

[0191] One way of implementation: if there is HARQ-ACK at the transmission moment of the first PUSCH, when the simultaneous transmission of PUCCH and PUSCH is not supported, if the UE receives downlink transmission, HARQ-ACK is carried on the grant-freePUSCH in slot n+5 For uplink transmission, if the UE does not receive the downlink transmission, only the grant-free PUSCH is transmitted in slot n+5 without HARQ-ACK; at this time, the base station can distinguish...

Abstract

The embodiment of the invention provides a transmission method and equipment, and the method comprises the steps that UE receives configuration information which is used for indicating whether to support the transmission of uplink control information UCI on a first physical shared channel PUSCH; and the UE transmits the first PUSCH and / or the UCI according to the configuration information. Thus, whether the UCI is transmitted on the first PUSCH or not is determined through the configuration information, inconsistent understanding of resources occupied by data transmission on the PUSCH by the UE and the network side equipment due to the fact whether the UCI exists or not is avoided, it is guaranteed that the network side equipment correctly receives the PUSCH, 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 and equipment. Background technique [0002] In a long term evolution (Long Term Evolution, LTE) wireless communication system, when a user equipment (User Equipment, UE) simultaneously has a physical shared channel (Physical Uplink Shared Channel, PUSCH) and uplink control information (Uplink Control Information, UCI) transmission, if UE supports simultaneous transmission of Physical Uplink Control Channel (PUCCH) and PUSCH, UCI can be transmitted on PUCCH, and data can be transmitted on PUSCH; if UE does not support simultaneous transmission of PUCCH and PUSCH, then UCI will be transmitted on PUSCH together with data. The UCI includes at least Hybrid Automatic RepeatreQuest ACKnowlegement (HARQ-ACK), Channel State Information (Channel State Information, CSI), and Scheduling Request (Scheduling Request, SR). [0003] In the LTE system, HARQ...
