Determining method, sending method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a determination method, a transmission method, a terminal device, and a network device.

Background

In the prior art, in order to save the overhead of Control signaling of a network, in addition to dynamic Scheduling, the NR (New Radio ) R15 standard also provides a Semi-Persistent Scheduling (SPS) method, which allows a network device (e.g., a base station) to perform SPS configuration on a user through a high-level signaling and to be activated through Downlink Control Information (DCI) of a physical layer, so as to achieve the purpose of periodically allocating Radio resources to a specific user.

The R15 SPS is mainly oriented to Voice over Internet Protocol (VoIP) service, the minimum period of the SPS supports 10ms, and only one activated SPS configuration is supported on one BWP (bandwidth Part), and the R16 standard supports Industrial Internet of Things (IIoT) service using the SPS, and the enhancement to the SPS includes two directions: the one hand is to support multiple SPS configurations activated simultaneously on one BWP, and the other hand is to shorten the SPS period from Rel 15 minimum 10ms to Rel 16 minimum 1 slot.

At present, there exists an irregular periodic IIoT, and no matter the above-mentioned SPS configuration mode supporting multiple simultaneous activations or the SPS configuration with a smaller period is used for supporting, there exists no data packet transmission at the activated SPS PDSCH (Physical Downlink Shared Channel) occasion, for this case, the terminal device does not know that the network device has no Downlink data packet, or receives the SPS PDSCH or reports HARQ-ACK (Hybrid automatic repeat request acknowledgement) for the SPS PDSCH, and thus, it may cause the waste of energy consumption of the terminal device.

In the method of this embodiment, instead of receiving or demodulating all PDSCHs and/or reporting HARQ-ACK, the terminal device determines to receive or mediate a first PDSCH or a first PDSCH group without corresponding PDCCH transmission based on the first indication information or the first rule, and/or generates or reports HARQ-ACK for the first PDSCH or the first PDSCH group; or, determining not to receive or not to demodulate the first PDSCH or the first PDSCH group without corresponding physical downlink control channel PDCCH transmission, and/or not generating or not reporting hybrid automatic repeat request acknowledgement HARQ-ACK for the first PDSCH or the first PDSCH group, so as to receive or demodulate the PDSCH which needs to be received or demodulated, and generate or report HARQ-ACK for the first PDSCH or the first PDSCH group which needs to generate or report HARQ-ACK, so as to reduce energy consumption of the terminal device.

Namely, the first PDSCH or the first PDSCH group which does not meet the first rule is not received or mediated and/or HARQ-ACK is not reported, so that the energy consumption is reduced and the PUCCH transmission reliability is improved.

Taking as an example one of the terms that a ratio of a reference signal received power, RSRP, or a reference signal received quality, RSRQ, or a received signal strength indication, RSSI, or a signal to interference plus noise ratio, SINR, of the first reference signal to the second reference signal is less than or equal to a first threshold, the first rule includes a case where the term is included, it may be determined not to receive or demodulate the first PDSCH or the first PDSCH group, and/or no hybrid automatic repeat request acknowledgement, HARQ, ACK, is generated or reported for the first PDSCH or the first PDSCH group, wherein a ratio of less than or equal to the first threshold may be understood as a ratio that may be less than the first threshold, or a ratio of less than or equal to (less than) the first threshold.
