Description

Receiving configuration method, data sending method, terminal and network equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a receiving configuration method, a data sending method, a terminal, and a network side device.
Background
The NR (new air interface) R15 protocol supports uplink and downlink beam management, which is mainly used for the high-frequency band. The current NR downlink may use SSB (Sychronization Signal Block, synchronization Signal block) and/or CSI-RS (Channel State Information-Reference Signal, channel state information Reference Signal) for beam selection. Taking beam selection and reporting using CSI-RS as an example, NR may configure n.gtoreq.1 report settings Reporting Settings (CSI-ReportConfig, CSI report configuration), m.gtoreq.1 resource settings Resource Settings (CSI-ResourceConfig, CSI resource configuration), 1 or 2 trigger status lists trigger states lists (aperiodic trigger status list apeichigerstatelist and semi-persistent trigger status list semipersistent on pusch-TriggerStateList) for terminal UE.
Each CSI Reporting Setting (CSI report setting) may be configured in a periodic, semi-persistent or aperiodic reporting manner, and when the radio resource control RRC signaling reporting quality (number of reports) is configured to cri-RSRP (reference signal received power), i.e. downlink beam measurement and L1-RSRP reporting are performed according to NZP CSI-RS (non-zero power CSI-RS), the network side associates one CSI Resource Setting (CSI resource setting) for each CSI Reporting Setting through RRC signaling.
Each CSI Resource Setting may contain S.gtoreq.1 CSI Resource Sets (CSI resource sets), each of which may contain several NZP CSI-RS resources. For periodic or semi-persistent CSI Resource Setting, the limit s=1. The network side can be configured into enabled (feasible) or disabled (infeasible) through RRC signaling, when RRC signaling=enabled, the terminal reports 2 different CRIs (CSI-RS identification, CSI-RS identifiers) each time, and the terminal can simultaneously receive the two CRIs corresponding to NZP CSI-RS resources; when RRC signaling = disabled, the UE reports nrofreporteddrs CRIs each time.
In the ongoing MIMO (multiple input multiple output) enhancement project of NR 16, multi-TRP (multiple transmission node) transmission is an important research direction, and for high frequencies, a typical scenario such as TRP1 (transmission node 1) and TRP2 (transmission node 2) uses Beam 1-5 (Beam 1-5) and Beam 2-2 (Beam 2-2) for incoherent joint data transmission with Panel 1 (Panel 1) and Panel 2 (Panel 2) of the terminal, respectively.
If implemented on the basis of the NR protocol of R15, examples are as follows:
the network side configures two periodic CSI Reporting Setting and CSI Reporting Setting 2 for the terminal;
CSI Reporting Setting 1 is associated with a periodic CSI Resource Setting 1, where 1 CSI Resource Set 1,CSI Resource Set 1 includes 5 NZP CSI-RS resources (NZP CSI-RS resources 1-1 to NZP CSI-RS resources 1-5, respectively), and the network side configures a group beam reporting=disabled for the terminal CSI Reporting Setting 1, and it is assumed that the terminal uses Panel 1 to receive NZP CSI-RS resources 1-1 with better performance, and uses Panel 2 to receive NZP CSI-RS resources 1-2 with better performance, so that the UE reports CRI 1-1 and CRI 1-2;
CSI Reporting Setting 2 is associated with a periodicity CSI Resource Setting 2, where 1 CSI Resource Set 2,CSI Resource Set 2 includes 5 NZP CSI-RS resources (NZP CSI-RS resources 2-1 to NZP CSI-RS resources 2-5, respectively), and the network side configures the group pbasedbeamreporting=disabled of CSI Reporting Setting 2 for the terminal, and if the terminal uses Panel 1 to receive NZP CSI-RS resources 2-1 with better performance, and uses Panel 2 to receive NZP CSI-RS resources 2-2 with better performance, the UE reports CRI 2-1 and CRI 2-2;
The problems here are: the network side cannot accurately judge which wave beam is respectively used by the TRP1 and the TRP2 to jointly transmit data according to the CRI 1-1 and the CRI 1-2 and the CRI 2-1 and the CRI 2-2 reported by the terminal, so that the receiving performance of the terminal is better. For example: if TRP1 uses beam1-1 and TRP2 uses beam2-1 for joint data transmission, both beams correspond to Panel 1 of the terminal, but if the terminal uses Panel 1 to receive data, it may not be possible to receive both beam1-1 and beam2-1 or there is a large interference between the data of TRP1 and TRP 2.

In this step, the CSI-RS identity may be simply referred to as CRI. I.e. the terminal reports Q CRI sets, each CRI set containing at least one CRI, each CRI set corresponding to one CSI resource set.
The terminal can simultaneously receive CSI-RS resources indicated by a plurality of CSI-RS identifiers, and the simultaneously received CSI-RS identifiers are respectively from a plurality of different CSI-RS identifier sets in the Q CSI-RS identifier sets; q is an integer greater than or equal to 1.

For another example, as shown in fig. 3, the terminal measures N CSI Resource sets in 1 number CSI Resource Setting, and when the network side can configure the terminal to report each time, Q number of the N Resource sets are selected for reporting, and K number of CRI (K is greater than or equal to 1) are reported from each Resource Set; the terminal reports Q groups of CRIs (indicated by CRIs set 1-Q), each group of K CRIs, and the terminal can simultaneously receive Q CRIs corresponding to NZP CSI-RS resources, wherein the Q CRIs are respectively from the Q groups of CRIs.

The terminal reports Q=1 groups of CRIs according to the measurement condition, wherein each group of K=2 CRIs; or the terminal reports q=2 groups of CRI, each group of k=2 CRI, the terminal can simultaneously receive 2 CRI corresponding to NZP CSI-RS resource, and the two CRI are respectively from 2 CRI groups.
