Embodiment 1

[0033] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, figure 1 It is a hardware structural block diagram of a mobile terminal according to a method for determining information in an embodiment of the present invention. Such as figure 1 As shown, the mobile terminal 10 may include one or more ( figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. Optionally, the above-mentioned mobile terminal also A transmission device 106 for communication functions as well as input and output devices 108 may be included. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and does not limit t...

Embodiment 2

[0298] In this embodiment, the parameter information of the measurement reference signal is determined according to an agreed rule, and the measurement reference signal is received according to the parameter information. The parameter information of the measurement reference signal is determined according to the agreed rules, including that the parameter information of the measured reference signal needs to meet the agreed rules.

[0299] Now the time unit offset information of AP-CSI-RS is configured in AP-CSI-RS set, but the time unit offset that can be configured in AP-CSI-RSset ranges from 0 to 4, where the time unit offset The offset indicates the time unit offset between the time unit where the DCI of the scheduled AP-CSI-RS is located and the time unit where the AP-CSI-RS is located. For example, an offset of 0 means that the DCI and AP-CSI-RS are in The same time unit, in this embodiment, a time unit may be a subframe, a slot, or a time unit including a predetermined n...

Embodiment 3

[0308] In NR, the BWP (Band width part, frequency domain bandwidth part) information of a CSI-RS resource ID is configured in the CSI-RS resource setting. When only CC information and CSI-RS resource ID information are given, the BWP (Band width part, frequency domain bandwidth part) information cannot be determined. For the BWP information of the CSI-RS resource ID, there may be at least one of the following agreed rules:

[0309] Rule 1: If a measurement reference signal resource is not configured with frequency domain bandwidth part information, (or a measurement reference signal belongs to a predetermined type, for example, the measurement reference signal belongs to a beam failure detection reference signal set, and the measurement reference signal belongs to a candidate Reference signal set, the measurement reference signal is a link detection (Radiolink Monitor) reference signal) The frequency domain bandwidth part of a measurement reference signal resource is one or mor...

Abstract

Provided are an information determination method, a signal receiving method and apparatus, the method comprising: determining quasi co-located reference signal information of an aperiodic measurement reference signal resource according to first information, the first information comprising at least one of the following: a relationship between a first threshold and a time interval, whether an intersection is null, and whether the intersection is null; the time unit offset is a preset rule; the time interval is a time interval between the control information for scheduling the aperiodic measurement reference signal resource and the aperiodic measurement reference signal resource; the intersection is an intersection between a time domain symbol set where the aperiodic measurement reference signal resource is located and a time domain symbol set where the target channel or the target signal is located; the time unit offset is the time unit offset associated with a non-periodic measurement reference signal resource set where the non-periodic measurement reference signal resources are located.

Description

[0001] This application is a divisional application of a Chinese patent application with the application number "201811143346.1", the application date is "September 28, 2018", and the title is "Information Determining Method, Signal Receiving Method and Device". technical field [0002] The present invention relates to the communication field, in particular, to a method for determining information, a method and a device for receiving signals. Background technique [0003] The aperiodic measurement reference signal is triggered by DCI (Downlink Control Information, downlink control information). In a system based on radio frequency beam communication, it is necessary to use a suitable receiving beam to receive the aperiodic measurement reference signal. It takes a certain time interval for the terminal to decode the DCI and use the receiving beam indicated by the DCI for the AP-CSI-RS. When the time interval between the DCI and the aperiodic measurement reference signal is s...
