Abstract
Description
Technical Field
[0001] The present invention relates to the field of wireless technology, and in particular to a beam switching method, device, network side equipment and terminal. Background Art
[0002] In conventional technology, the primary synchronization signal (PSS), the secondary synchronization signal (SSS) and the physical broadcast channel (PBCH) are transmitted in the synchronization signal block (SSB). Among them, the transmission of SSB is periodic, and is sent according to the synchronization measurement timing configuration (SMTC) period and SMTC duration.
[0003] Among them, multiple SSBs are sent within the SMTC duration, and the sending directions of SSBs with different indexes are different. Through SSB beam sweeping, full coverage of the cell is achieved.
[0004] However, there are coverage holes in actual wireless networks. For example, due to penetration damage, the signal inside a building is poor. One way to solve this problem is to achieve coverage enhancement by properly configuring SSB transmission. Specifically, in the extended coverage scenario, the transmission direction of SSBs with different indexes within the SMTC duration is likely to be the same, and extended coverage is achieved through retransmission. Based on this method, there will be both normal coverage SSBs and coverage enhancement SSBs in the network, and switching between SSBs with different coverage capabilities has become the research focus of current wireless network technology.

[0099] In another implementation manner, the service beam is one of the beam coverage levels, and the target beam is a coverage level in the beam coverage level that is different from the coverage level of the service beam.
[0100] It should be noted that the normal coverage beam is a beam that is normally transmitted according to a pre-configured transmission period, and the extended coverage beam is a beam that achieves coverage enhancement through retransmission.

Optionally, in one embodiment, the beam-related information may also include beam information of a beam operating in an activated BWP and / or beam information of a beam operating in a target BWP.

[0119] It should be noted that, in the embodiment of the present invention, the measurement interval configuration information includes: a measurement interval period, a measurement interval duration and / or a measurement interval time domain start offset.
[0120] In an embodiment of the present invention, the measurement start information is used to indicate parameter information for the terminal to start beam quality measurement. Optionally, the measurement start information includes at least one of a measurement start threshold, a first count number, and a first timing duration.
[0121] It should be noted that the measurement start threshold includes but is not limited to only including reference signal receiving power (Reference Signal Receiving Power, RSRP), reference signal receiving quality (Reference Signal Receiving Quality, RSRQ), signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) and / or demodulation bit error rate, which is used to indicate that the terminal starts measuring the target beam when the beam quality of the currently connected service beam meets the threshold value specified by the measurement start threshold.
[0122] The first counting number is used to instruct the terminal to start measuring the target beam when the number of detections that the beam quality meets the preset quality condition exceeds the first counting number when detecting the beam quality of the currently connected source beam.
[0123] The first timing duration is used to instruct the terminal to detect the beam quality of the connected service beam. If the beam quality meets the preset quality condition within the first timing duration, the measurement of the target beam is started.
[0124] Specifically, according to the measurement start information, when at least one of the following conditions is met, the measurement of the target beam is started:
[0125] The beam quality meets the measurement start threshold;
[0126] The number of times that the beam quality satisfies the measurement start threshold is greater than or equal to the first count number;
[0127] During the first timing period, the beam quality meets the measurement start threshold;
[0128] During the first timing duration, the number of times that the beam quality meets the measurement start threshold is greater than or equal to the first count number.

[0133] When the measurement start information includes the measurement start threshold and the first timing duration, if the service beam is a beam in the first coverage range, the target beam is a beam in the second coverage range, the first coverage range is not better than the second coverage range, and the beam quality within the first timing duration is less than or equal to the measurement start threshold, the target beam quality is turned on;
[0134] When the measurement start information includes the measurement start threshold and the first timing duration, if the service beam is the second coverage range beam, the target beam is the first coverage range beam, the first coverage range is not better than the second coverage range, and the beam quality within the first timing duration is greater than or equal to the measurement start threshold, then the target beam measurement is started;
[0135] When the measurement start information includes the measurement start threshold, the first count number and the first timing duration, if the service beam is a beam in the first coverage range, the target beam is a beam in the second coverage range, the first coverage range is not better than the second coverage range, and the number of times that the beam quality is less than or equal to the measurement start threshold within the first timing duration is greater than or equal to the first count number, then the target beam measurement is started;
[0136] When the measurement startup information includes the measurement startup threshold, the first counting number and the first timing duration, if the service beam is the second coverage range beam, the target beam is the first coverage range beam, the first coverage range is not better than the second coverage range, and the number of times the beam quality within the first timing duration is greater than or equal to the measurement startup threshold is greater than or equal to the first counting number, then the target beam measurement is started.
[0137] Based on the above, the beam switching method described in the embodiment of the present invention further includes:
[0138] When the beam quality of the serving beam of the terminal reaches a first threshold and / or the beam quality of the target beam reaches a second threshold, switching is performed from the serving beam to the target beam.
[0139] The first threshold and the second threshold may be issued by a network side device or may be preset in the protocol.
[0140] It should also be noted that the service beam and the target beam can be SSB-based beams or CSI-RS-based beams respectively.
[0141] Wherein, when any of the following conditions is met, it can be determined that the beam quality of the serving beam of the terminal reaches the first threshold:
[0142] The beam quality of the serving beam reaches a first threshold;
[0143] The beam quality of the serving beam meets a first threshold for a first preset number of consecutive measurements;
[0144] Within a first preset time period, the beam quality of the serving beam meets a first threshold;
[0145] Within the second preset time length, the number of times that the beam quality of the serving beam meets the first threshold reaches or exceeds the second preset measurement number;
[0146] Among the multiple service beams, beam qualities of M service beams with the highest beam qualities meet a first threshold, where M is a positive integer.
[0147] When any of the following conditions is met, it can be determined that the beam quality of the target beam of the terminal reaches the second threshold:
[0148] The beam quality of the target beam reaches a second threshold;
[0149] After a first preset number of consecutive measurements, the beam quality of the target beam meets a second threshold;
[0150] Within the first preset time period, the beam quality of the target beam meets the second threshold;
[0151] Within a second preset time length, the number of times that the beam quality of the target beam meets the second threshold reaches or exceeds a second preset measurement number;
[0152] Among the multiple target beams, beam qualities of M target beams with the highest beam qualities meet a second threshold, where M is a positive integer.
[0153] It should be noted that the above-mentioned beam quality includes at least one of reference signal receiving power (Reference Signal Receiving Power, RSRP), reference signal receiving quality (Reference Signal Receiving Quality, RSRQ), signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) and demodulation bit error rate.
[0154] Based on the above, the first threshold and the second threshold may be threshold values using at least one of RSRP, RSRQ, SINR and demodulation bit error rate as evaluation parameters. When the beam quality decreases or increases to the first threshold or the second threshold, it is determined that the beam quality reaches or satisfies the first threshold or the second threshold.
[0155] Optionally, the beam switching method described in the embodiment of the present invention further includes:
[0156] Receive indication information sent by the network side device to indicate whether to perform measurement reporting.
[0157] Optionally, the network side device may send indication information indicating whether to perform measurement reporting to the terminal through broadcast or Radio Resource Control (RRC) message or the like.
[0158] Furthermore, the measurement configuration information sent by the network side device may also be sent to the terminal via broadcast or RRC message.
[0159] Optionally, the beam switching method described in the embodiment of the present invention further includes: performing beam measurement reporting when at least one of the following conditions is met:
[0160] The beam quality of the measurement beam reaches a third threshold;
[0161] Within the second preset time length, the beam quality of the measurement beam meets a fourth threshold;
[0162] Within a third preset time length, the number of times that the beam quality of the measurement beam meets the fifth threshold reaches a second count number;
[0163] Among the multiple measurement beams, the beam qualities of M beams with the highest beam qualities reach a sixth threshold, where M is an integer;
[0164] The beam quality of the service beam in the measurement beam is lower than or equal to a seventh threshold, and the beam quality of the target beam in the measurement beam is higher than or equal to an eighth threshold.
[0165] It should be noted that any of the above-mentioned condition information may be issued by a network-side device or may be pre-defined through a protocol.
[0166] In addition, the above-mentioned beam quality reaches the third threshold, the fourth threshold, the fifth threshold or the sixth threshold, including the beam quality rising to the third threshold, the fourth threshold, the fifth threshold or the sixth threshold, and also includes the beam quality falling to the third threshold, the fourth threshold, the fifth threshold or the sixth threshold.
[0167] The aforementioned measurement beam includes a service beam and / or a target beam, wherein for the service beam and the target beam, the aforementioned thresholds may be different respectively.
[0168] The beam switching method described in the embodiment of the present invention can optionally also introduce measurement reporting events of the terminal to help the network discover coverage holes or coverage blind spots.
[0169] Therefore, optionally, the beam switching method further includes: defining at least one of the following events as a measurement reporting event:
[0170] The beam quality of the measurement beam satisfies the first condition for a first preset number of consecutive measurements;
[0171] Within a fourth preset time period, the beam quality of the measurement beam satisfies the second condition;

[0173] Among the multiple measurement beams, the beam qualities of N beams with the highest beam qualities satisfy the fourth condition; wherein N is an integer;
[0174] The beam quality of the service beam in the measurement beam is lower than or equal to the fifth condition, and the beam quality of the target beam in the measurement beam is higher than or equal to the sixth condition;
[0175] The difference between the beam quality of the service beam in the measurement beam and the beam quality of the target beam in the measurement beam satisfies the seventh condition.
[0176] It should be noted that any of the above-mentioned condition information may be issued by a network-side device or may be pre-defined through a protocol.
[0177] Furthermore, in each of the above measurement reporting events, the beam quality satisfies the first condition, the second condition, the third condition or the fourth condition, including at least one of the following situations:
[0178] The beam quality is lower than or equal to the corresponding threshold value;
[0179] The beam quality is higher than or equal to the corresponding threshold.
[0180] For example, for the first preset number of consecutive measurements, the beam quality of the measurement beam meets the first condition in the following situations:
[0181] In one implementation mode, when a beam quality change between any two measurements of a measured beam within a preset number of times satisfies a preset threshold (first condition), the beam quality is reported to a network side device;
[0182] In another implementation manner, when the beam quality of each measurement of the measured beam meets a preset threshold (first condition) within a preset number of times, the beam quality is reported to the network side device;
[0183] In another implementation manner, when the beam quality changes between all two consecutive measurements of the measured beam within a preset number of times meet a preset threshold (first condition), the beam quality is reported to the network side device;
[0184] In yet another implementation manner, when the final beam quality measurement of the measurement beam meets a preset threshold (first condition), the beam quality is reported to the network side device.
[0185] It should be noted that the above-mentioned change in beam quality includes an increase in beam quality and a decrease in beam quality.
[0186] The above-mentioned measurement beam includes a service beam and / or a target beam, wherein the above-mentioned conditions may be different for the service beam and the target beam.
[0187] Further, for a situation in which the beam qualities of N beams with the highest beam qualities among the multiple measurement beams satisfy the fourth condition, it includes:
[0188] The quality of the N beams with the highest beam quality among the serving beam or the beams serving the BWP is lower than a certain threshold; or
[0189] The quality of the N beams with the highest beam quality among the serving beam or the beams serving the BWP is lower than a certain threshold, and the quality of the target beam is higher than a certain threshold.
[0190] It should be noted that, in an embodiment of the present invention, when the beam quality of the N measurement beams with the highest beam quality in the service beam or the beam serving the BWP is lower than a certain threshold, it means that all beams in the current coverage range cannot meet the demand and beam switching is required.
[0191] In an embodiment of the present invention, the above-mentioned thresholds and conditions may be based on at least one of RSRP, RSRQ, SINR and demodulation bit error rate as an evaluation parameter, and the specific content of each threshold and condition may be issued by a network side device or may be pre-specified by a protocol.
