Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and specifically to a measurement method, apparatus, device, and readable storage medium. Background Art

[0002] In order to meet the needs of some IoT use cases, such as industrial wireless sensor networks, smart cities, and wearable devices, lightweight (Reduced Capability, Redcap) terminals reduce terminal complexity and cost by reducing bandwidth, reducing the number of transmitting and receiving antennas, and reducing terminal processing capabilities.

[0003] The bandwidth part (Bandwidth Part, BWP) of the RedCap terminal is reduced. For example, limited by the 20MHz bandwidth, the frequency selection scheduling gain of the RedCap terminal is small, which brings about the problem of reduced coverage. In order to allow RedCap to maintain a coverage level comparable to that of Enhanced Mobile Broadband (eMBB), some companies have proposed that BWP frequency hopping on the full bandwidth can enhance coverage. The selection of BWP frequency hopping points requires the knowledge of the full bandwidth channel state information (Channel State Information, CSI). Generally, the BWP with better CSI brings greater coverage gain. In order to obtain frequency selection gain, the network needs to obtain CSI on the full bandwidth, such as 100MHz bandwidth.

[0004] In the prior art, CSI measurements are performed on a per BWP basis. A terminal can be configured with up to four BWPs, but only one BWP is activated at the same time, and CSI measurements are performed only on the activated BWP. If you want to measure the CSI of other BWPs, you need to switch to other BWPs for measurement. There are three existing BWP switching methods, namely Radio Resource Control (RRC) configuration, timer triggering, and dynamic downlink control information (DCI) indication. It is difficult to obtain full-bandwidth CSI using existing CSI measurement technology, so it is necessary to establish a full-bandwidth CSI measurement mechanism, such as configuring a CSI measurement pattern to achieve full-bandwidth CSI measurement.

[0005] However, when a terminal measures the full-bandwidth CSI according to a certain measurement pattern, how to avoid possible conflicts with scheduled data transmission is an urgent problem to be solved. Summary of the invention

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0052] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems.

However, the following description describes a new radio (NR) system for example purposes, and NR terms are used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as the 6th Generation (6G) communication system.

[0053] Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network side device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

As long as the same technical effect is achieved, the base station is not limited to the specified technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0054] See also Figure 2 , an embodiment of the present application provides a measurement method, which is executed by a terminal (such as a RedCap terminal), and the specific steps include: step 201 and step 202.

[0055] Step 201: after monitoring a physical downlink control channel (PDCCH), start or restart a timer;

[0056] When a PDCCH related to the terminal is monitored, full-bandwidth CSI measurement based on a measurement pattern (or referred to as a CSI measurement pattern) is stopped, and a timer is started or restarted;

[0057] The measurement pattern is determined in the following manner: taking the reference BWP as the granularity, the full bandwidth is divided into multiple grids, each of which corresponds to a measurement resource (e.g., BWP), and in the measurement pattern, if the measurement opportunity arrives, the corresponding BWP switching is performed to achieve the measurement resource switching triggered by the measurement opportunity. It can be understood that the specific value of the reference BWP can be adjusted according to the situation. For example, if the system bandwidth is 20MHz, the reference BWP can be 4MHz. In the embodiment of the present application, the reference BWP is not specifically limited.

[0058] Step 202: During the operation of the timer, CSI is measured and / or reported in the first BWP (or activated BWP) indicated by the first DCI carried by the PDCCH according to the CSI reporting configuration (CSI-ReportConfig).

[0059] In an embodiment of the present application, the method further includes:

[0060] Before the timer is started or when the timer expires, CSI measurement and / or reporting is performed on at least one time-frequency resource (such as BWP) according to the CSI reporting configuration.

[0061] See also Figure 3 In order to achieve full-bandwidth CSI measurement, the measurement resource switching method triggered by the measurement occasion is realized by configuring periodic measurement resources. The terminal divides the full bandwidth into several grids with the reference BWP bandwidth as the granularity, and numbers the grids from 0 in ascending order of frequency (BWP0~BWP4). Configure periodic CSI measurement reporting to achieve full-bandwidth channel measurement. When the measurement occasion arrives, perform the corresponding BWP switching to achieve measurement resource switching triggered by the measurement occasion.

[0062] For example, the time slot number at which the CSI measurement occasion arrives satisfy:

[0063]

[0064] Where n f is the frame number, is the number of time slots contained in each frame, T offset is the time slot offset number, T CSI-RS is the CSI measurement period (ie, the CSI measurement occasion arrival period).

[0065] In time slot The grid number of CSI measurement can be expressed as:

[0066]

[0067] in is the total number of grids, B sys is the system bandwidth, B BWP is the reference BWP bandwidth.

[0068] In the embodiment of the present application, data scheduling has a higher priority than measurement, and the terminal will still monitor the physical downlink control channel (PDCCH) of the activated BWP during the measurement interval. Specifically, there are two scheduling and monitoring examples as follows:

[0069] Example 1: When the activated BWP is different from the BWP where the measurement resource is located, the terminal performs measurement and reporting on the measurement resource, and monitors the PDCCH of the activated BWP after the measurement is completed.

[0070] Example 2: When the activated BWP is the same as the BWP where the measurement resource is located, the terminal performs measurement and reporting on the measurement resource and monitors the PDCCH at the same time.

[0071] In an embodiment of the present application, when PDCCH scheduling related to the terminal is monitored and data transmission is required, the full-bandwidth CSI measurement based on the pattern is stopped, the timer is started or restarted, the scheduled activated BWP is switched to, and data transmission is performed within the validity period of the timer. At the same time, measurement and reporting are performed on the currently activated BWP with the configured CSI period, and the measurement period is the same as the configured CSI measurement pattern.

[0072] In an embodiment of the present application, the method further includes:

[0073] If the monitored PDCCH carries a second DCI, and the BWP indication field in the second DCI indicates a second BWP different from the first BWP, the timer is restarted, and CSI measurement and / or reporting is performed according to the second BWP indicated by the second DCI.

[0074] In an embodiment of the present application, data transmission ends during the timer running, and measurement and PDCCH monitoring continue on the currently activated BWP. If a new schedule is monitored, the timer is restarted, and data transmission, measurement and reporting are performed according to the activated BWP of the data schedule.

[0075] In an embodiment of the present application, the method further includes:

[0076] After the timer expires, CSI measurement and / or reporting is performed based on the measurement opportunity and time-frequency resources determined by the measurement configuration.

[0077] In an embodiment of the present application, performing CSI measurement and / or reporting based on the measurement timing and time-frequency resources determined by the measurement configuration includes:

[0078] Mode 1: Determine a third BWP (currently activated BWP), where the third BWP is a BWP that monitors the first DCI carried by the PDCCH or an activated BWP during the timer operation; starting from the third BWP, perform CSI measurement and / or reporting based on a predefined or configured BWP order;

[0079] like Figure 4 As shown, the measurement resource is switched back to the grid corresponding to the original measurement pattern, and measurement starts according to the original measurement pattern. The BWP number of the measurement is expressed as:

[0080] The measured BWP number still passes The advantage is that the grid number is only related to the current time and the implementation is simple.

[0081] Method 2: Determine the third BWP (the currently activated BWP), where the third BWP is the BWP that monitors the first DCI carried by the PDCCH or the activated BWP during the timer operation, and start from the previous BWP or the next BWP (measurement grid) of the three BWPs. Perform CSI measurement and / or reporting in a predefined or configured BWP order, that is, restart a measurement pattern from the grid where the measurement resource is currently located.

[0082] like Figure 5 As shown, a new measurement pattern is restarted from the grid where the currently activated BWP is located. The measured BWP number is represented as: in The number of the currently activated BWP. The advantage is that the CSI of the current grid is usually good, and the measurement starts from the grid adjacent to the activated BWP to improve the efficiency of finding high-quality channels.

[0083] Method three: perform CSI measurement and / or reporting according to the relationship between the measurement BWP and the time slot in the measurement configuration.

[0084] In the embodiment of the present application, the running period of the timer is related to the activation duration of the BWP, for example, in units of slots, which can be a value greater than or equal to 1. And / or, the time length of the timer is agreed upon by the protocol or configured on the network side.

[0085] In the embodiment of the present application, by switching the measurement resources triggered by the measurement opportunity, it is possible to support full bandwidth CSI measurement when the BWP is frequency hopping. By using the timer, it is possible to reduce the conflict between measurement and transmission. By performing measurement on the currently activated BWP within the validity period of the timer, the channel information of the currently activated BWP can be obtained in a timely manner. Furthermore, by setting a frequency hopping measurement pattern recovery method triggered by a timer, data scheduling loss can be avoided and data transmission delay can be avoided.

[0086] The following describes the embodiments of the present application in combination with Embodiment 1 and Embodiment 2.

[0087] Embodiment 1:

[0088] like Figure 6 As shown, at time 0, the terminal activates BWP0, and the periodic CSI measurement pattern starts from time 0. BWP0 is measured from time 0, ΔT is the measurement duration of each time, T CSI-RS is the arrival period of the measured occasion, T CSI-RS Longer. From time ΔT to T CSI-RS No measurement is performed during this period, but the PDCCH of the BWP where the measurement resource is located or the activated BWP is monitored. If no scheduling is monitored, at time T CSI-RS Start measuring BWP1 according to the CSI measurement pattern. The CSI measurement pattern is carried out normally until a schedule is heard at time T1, and the active BWP of the schedule is BWP0. Stop the periodic CSI measurement pattern, start the timer, switch to BWP0 for data transmission, and measure on BWP0 with the configured CSI period. At time T2, the data transmission ends, but the timer is still valid, and continue to measure on BWP0 and monitor PDCCH. Until time T3, the timer expires and no new schedule is heard. After the timer expires, at time T0 (T0-T1<T CSI-RS )Measure the occasion arrival and restore the periodic CSI measurement pattern.

[0089] Embodiment 2:

[0090] like Figure 7 As shown, at time 0, the terminal activates BWP0, and the periodic CSI measurement pattern starts from time 0. BWP0 is measured from time 0, ΔT is the measurement duration of each time, T CSI-RS is the arrival period of the measured occasion, T CSI-RS Shorter. From time ΔT to T CSI-RS No measurement is performed during this period, but the PDCCH of the BWP where the measurement resource is located or the activated BWP is monitored. If no scheduling is monitored, at time T CSI-RSStart measuring BWP1 according to the CSI measurement pattern. The CSI measurement pattern is carried out normally until a schedule is heard at time T1, and the active BWP scheduled is BWP0. Stop the periodic CSI measurement pattern, start the timer, switch to BWP0 for data transmission, and measure on BWP0 with the configured CSI period. At time T2, data transmission ends, but the timer is still valid, and measurements on BWP0 continue and PDCCH is monitored. At time T CSI-RS , the timing has not ended and a new schedule is monitored. The active BWP scheduled is BWP2. The timer is restarted and switched to BWP2 for data transmission and measurement. At time T4, the data transmission ends, but the timer is still valid. Measurements are continued on BWP2 and PDCCH is monitored until time T5 (T5-T3>T CSI-RS ), the timer expires and no new schedule is detected. After the timer expires, the measurement occasion arrives at time T0, and the periodic CSI measurement pattern is restored.
