Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and in particular to an information receiving method, an information sending method and device, a storage medium and a computer program product. BACKGROUND

[0002] In a conventional beam management process, a network configures / activates frequent periodic or semi-persistent beam reporting, or triggers frequent aperiodic beam reporting, to obtain the best / preferred beam for data / control transmission. However, the above method will cause a large overhead of uplink (UL) reporting and control signaling. At the same time, if a beam report with a low frequency is configured, the beam report of a user equipment (UE) can be outdated, and the network cannot always obtain the "best / preferred" beam based on the possibly outdated beam report, resulting in low accuracy of the network in obtaining the beam and thus causing a decline in communication performance. Considering that a UE has a better and more timely understanding of beam quality changes, a beam reporting process initiated by the UE can enable the network to obtain more timely beam reports while reducing reporting overhead. In such a process, if the UE determines, for example, that the current beam quality has deteriorated, the UE can trigger a beam report, and the network does not need to configure or trigger frequent reporting. When the terminal triggers a beam report, one decision criterion is that the quality of at least one new beam is higher than that of the current beam by a threshold value, and another decision criterion is that the quality of the current beam is lower than a threshold value. If the decision is made based on the layer 1 reference signal receiving power (L1-RSRP) of the current beam and the new beam, the interference condition of the beam cannot be reflected, so that the selected beam is not the optimal beam, and the interference condition between multiple users cannot be considered.

[0024] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0026] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments, but it is understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other as long as there is no conflict. It should also be noted that the terms "first, second, third" used in the embodiments of the present application are only used to distinguish similar objects, and do not represent a specific order of the objects. It is understood that "first, second, third" can be interchanged in a specific order or sequence as long as it is allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0027] Three beam measurement mechanisms of Layer 1-Signal to Interference plus Noise Ratio (L1-SINR) are described as follows:

[0028] The first mechanism is to measure L1-SINR based on single-port Channel State Information-Reference Signal (CSI-RS). The base station transmits single-port CSI-RS, and the terminal extracts useful signals by using the CSI-RS sequence for sequence correlation, and calculates L1-SINR by taking the remaining energy of the CSI-RS transmission time-frequency resource position except the useful signals as interference.

[0029] The second mechanism is that the base station transmits CSI-RS or Synchronization Signal and Physical Broadcast Channel Block (SSB) as channel measurement resources for measuring useful signals, and configures Zero-Power (ZP) CSI-RS resources as interference measurement resources for measuring interference signals. The terminal receives channel measurement resources and interference measurement resources using the same analog domain receive beam direction, and calculates L1-SINR by using one-to-one mapping of the channel measurement resources and the interference measurement resources. The signal energy received by the terminal at the time-frequency resource position of the ZP CSI-RS resource mainly reflects the interference situation of the terminal by the neighboring cells, and can be used for inter-cell interference coordination.

[0030] The third mechanism is that the base station transmits a CSI-RS or SSB as a channel measurement resource for measuring a useful signal, the base station configures a non-zero power (NZP) CSI-RS resource as an interference measurement resource for measuring an interference signal, and the terminal receives the channel measurement resource and the interference measurement resource in the same analog domain receive beam direction and calculates the L1-SINR in a one-to-one mapping manner. The NZP CSI-RS resource can be a useful signal of other users in the cell, and therefore the interference measured by the terminal on the NZP CSI-RS mainly reflects the interference between multiple users in the cell, which can be used for pairing multiple users in the cell.

[0031] The L1-SINR measurement resource configuration mode is that the network side configures a channel measurement resource (CMR) and an interference measurement resource (IMR) through radio resource control (RRC) signaling, and the terminal performs periodic or semi-persistent or aperiodic measurement and reporting. As shown in Table 1.

The terminal device can also be a handheld device with wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future evolved network, and the like. The present application is not limited by implementation.

[0037] In the embodiments of the present application, the method for determining the interference measurement resource according to the received network configuration information can specifically be: determining the interference measurement resource according to N resources indicated one-to-one by N TCI states in a MAC CE activating the TCI states.

[0038] In the embodiments of the present application, the N resources indicated one-to-one by the N TCI states in the MAC CE can include an interference measurement resource identifier, or a ZP CSI-RS identifier, or a CSI-IM identifier, or an SSB identifier, or a NZP CSI-RS identifier. The specific one can be selected according to the actual situation, and the embodiments of the present application are not specifically limited.

[0039] For example, the format of the MAC CE is shown in Table 2. The MAC CE carries N TCI states (TCI state ID 1-TCI state ID N) and carries an indicated resource corresponding to each TCI state, such as TCI state ID 1 corresponding to an indicated resource of IMR ID 1, or ZP CSI-RS ID 1, or NZP CSI-RS ID 1, or SSB ID 1, or CSI-IM ID 1, TCI state ID 2 corresponding to an indicated resource of IMR ID 1, or ZP CSI-RS ID 1, or NZP CSI-RS ID 1, or SSB ID 1, or CSI-IM ID 1, and TCI state ID N corresponding to an indicated resource of IMR ID N, or ZP CSI-RS ID N, or NZP CSI-RS ID N, or SSB ID N, or CSI-IM ID N.

[0041]

[0042] In an optional embodiment, the terminal device determines the quasi co-location (QCL) reference signals (RSs) of the N TCI states activated by the MAC CE as N channel measurement resources, and determines the N resources corresponding to the N TCI states in the MAC CE as N interference measurement resources.

[0043] In the embodiment of the application, the terminal device determines the N resources corresponding to the N TCI states in the MAC CE as N interference measurement resources, and measures N L1-SINRs corresponding to the channel measurement resources and the interference measurement resources.

[0044] In another optional embodiment, the terminal device determines the QCL RSs of the TCI states indicated by the downlink control information (DCI) as channel measurement resources, and determines the resource corresponding to the TCI state indicated by the DCI among the N resources corresponding to the N TCI states in the MAC CE as an interference measurement resource.

[0045] In the embodiment of the application, the terminal device finds the measurement resource corresponding to the TCI state ID indicated by the DCI in the MAC CE as an interference measurement resource according to the N resources corresponding to the N TCI states in the MAC CE, and further calculates an L1-SINR.

[0046] In another optional embodiment, the QCLed synchronization signal / physical broadcast channel block (SSB) of the RS of the QCL of the DCI-indicated QCL is taken as the channel measurement resource, and the SSB of the QCL of the N resources corresponding to the N TCI states in the MAC CE is taken as the interference measurement resource.

[0047] In the embodiments of the present application, the terminal device finds the SSB of the QCL of the measurement resource corresponding to the DCI-indicated TCI state ID in the MAC CE as the interference measurement resource according to the one-to-one correspondence between the N resources in the MAC CE and the N TCI states, and further calculates 1 L1-SINR.

[0048] Based on the above three optional embodiments, the QCL type D of the channel measurement resource is assumed as the QCL type D of the corresponding interference measurement resource, or the same QCL type D is used to receive the channel measurement resource and the interference measurement resource, or the same beam direction is used to receive the channel measurement resource and the interference measurement resource, to measure the interference measurement resource and obtain the L1-SINR.

[0049] In the embodiments of the present application, the method for determining the interference measurement resource according to the received network configuration information can further be: determining the interference measurement resource corresponding to the channel measurement resource according to the one-to-one association relationship between the RRC-configured channel measurement resource and the interference measurement resource; wherein the channel measurement resource is the RS of the QCL of the MAC CE-activated TCI state, the RS of the QCL of the DCI-indicated TCI state, the SSB of the QCL of the RS of the MAC CE-activated TCI state, or the SSB of the QCL of the RS of the DCI-indicated TCI state.

[0050] Based on the above embodiments, in the embodiments of the present application, the channel measurement resource can be an SSB or a CSI-RS, and the interference measurement resource can be an SSB, an NZP-CSI-RS, or a ZP-CSI-RS.

[0051] It should be noted that the MAC CE activates and / or updates the one-to-one association relationship between the RRC-configured channel measurement resource and the interference measurement resource.

[0052] Based on the above embodiments, when the terminal device takes the RS of the QCL of the MAC CE activated TCI state or the RS of the QCL of the DCI indicated TCI state or the SSB of the QCL of the RS of the MAC CE activated TCI state or the SSB of the QCL of the RS of the DCI indicated TCI state as the channel measurement resource, the terminal determines the interference measurement resource corresponding to the RS according to the one-to-one association relationship between the channel measurement resource and the interference measurement resource configured by the RRC or the MAC CE, and calculates the L1-SINR.

[0053] In the embodiments of the present application, the method for determining the interference measurement resource according to the received network configuration information can further be that one interference measurement resource is configured by the RRC.

[0054] Based on the above embodiments, taking the RS of the QCL of the DCI indicated TCI state or the SSB of the QCL of the RS of the DCI indicated TCI state as the signal measurement resource, the L1-SINR is measured by assuming to receive the interference measurement resource by the reception beam direction of the RS or the SSB or the QCL type D.

[0055] It can be understood that the network device configures the network configuration information for the terminal device, and the terminal can determine the interference measurement resource for measuring the L1-SINR based on the network configuration information. At this time, the terminal triggers the beam measurement based on the L1-SINR. Since the terminal perceives the change of the beam quality more timely, the terminal triggering the beam measurement can reduce the overhead of the UL report and the control information, and the triggering of the beam measurement also considers the interference situation of the beam, so that the beam decision based on the L1-SINR reflects the interference situation of the beam, improves the accuracy of obtaining the "best / preferred" beam, and further improves the communication performance.

[0056] Based on the above embodiments, the embodiments of the present application also propose an information sending method applied to a network device, as shown in the Figure 2 The method can include:

[0063] In the embodiments of the present application, the method for determining the interference measurement resource based on the network configuration information sent by the network device can further be: RRC configuring a one-to-one association relationship between the channel measurement resource and the interference measurement resource; wherein the channel measurement resource is a RS with QCL of a TCI state activated by a MAC CE, or a RS with QCL of a TCI state indicated by DCI, or a SSB with QCL of a RS with QCL of a TCI state activated by a MAC CE, or a SSB with QCL of a RS with QCL of a TCI state indicated by DCI.

[0064] Based on the above embodiments, the MAC CE activates and / or updates the one-to-one association relationship between the RRC configured channel measurement resource and the interference measurement resource.
