For any path in multipath propagation, the time and phase of arrival at the UE receiving antenna array are equally spaced

[0103] FIG. 1c is a schematic diagram of a near field UE receiving an electromagnetic wave, according to an example embodiment of the present disclosure. As shown in FIG. 1c, if the UE is located in the near field, the electromagnetic wave received by the UE is a spherical wave, and the beam for the UE is a three-dimensional (3dimension, 3D) beam surrounding the target UE. For any path in multipath propagation, the time and phase of arrival at the UE receiving antenna array are no longer equally spaced.

[0104] In some embodiments, different transmission beams (base station side transmission beams, configured based on transmission configuration indicator state (TCI state)) can be configured for ports (or port groups, or antenna subarrays), that is, the beams of different ports are independently configured.

[0105] In some embodiments, beam failure recovery can be implemented based on a cell or a transmission and receiving point (TRP) or a panel. However, in the high frequency large-scale antenna scenario, for a near field terminal, the beams corresponding to different ports are independently configured, resulting in different optimal beams on different ports on a TRP / panel. If the beam failure recovery is still based on the TRP / panel, the channel conditions of the beams on each different port cannot be reflected.

[0106] Therefore, the present disclosure provides a communication method, by sending first information to a network device in response to detecting that a wireless link quality corresponding to a first reference signal resource on a first reference signal resource set is lower than a first threshold value, the first information being used for link failure recovery or beam failure recovery of a first port, wherein the first reference signal resource set is used for failure detection of the first port. Thus, when the beam-based transmission performance on different ports is poor, the beam failure recovery based on the new beam can be detected as soon as possible, thereby ensuring the performance of the beam-based transmission on each port as much as possible to improve the communication efficiency.

[0118] FIG. 2 is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the present embodiment relates to a communication method for the communication system 100, the above-mentioned method comprising:

[0119] Step S2101, the terminal 101 determines a first reference signal resource set.

[0120] In some embodiments, the terminal can determine the first reference signal resource set. For example, the first reference signal resource set can be determined based on the configuration of the network device. That is, the network device can configure the reference signal resource set for the first port failure detection. In the present disclosure, the reference signal resource set for the first port failure detection is referred to as the first reference signal resource set. For another example, the first reference signal resource set can be determined based on other reference signal resources determined as the first reference signal resource. Wherein, the other reference signal resources can be reference signal resources configured by the network device for other purposes.

[0121] In some embodiments, the first reference signal resource set is used for the failure detection of the first port.

[0122] In some embodiments, the failure detection can include link failure detection, or beam failure detection.

[0123] In some embodiments, the first port can be one or more. For example, when the first port is multiple, the terminal can determine the first reference signal resource set of each first port respectively. The multiple first ports are different ports of the same TRP / panel.

[0124] In some embodiments, the first port can also be a first port group, a first antenna array unit, a first antenna subarray, a first subarray, a first panel, and a first sub-panel.

[0125] Step S2102, in response to detecting that the wireless link quality corresponding to the first reference signal resource on the first reference signal resource set is lower than the first threshold value, the terminal 101 sends first information to the network device 102.

[0126] In some embodiments, the network device 102 receives the first information sent by the terminal 101. The first information is sent by the terminal in response to detecting that the wireless link quality corresponding to the first reference signal resource on the first reference signal resource set is lower than the first threshold value.

[0127] In some embodiments, the wireless link quality may, for example, include but is not limited to at least one of the following: Block Error Rate (BLER) of a Physical Downlink Control Channel (PDCCH), Reference Signal Receiving Power (RSRP), Signal to Interference plus Noise Ratio (SINR), Reference Signal Received Quality (RSRQ). The terminal may, if detecting that the wireless link quality corresponding to the first reference signal resource on the first reference signal resource set is lower than a first threshold value, send first information to the network device. The size of the first threshold value is not limited by the present disclosure.

[0128] In some embodiments, the wireless link quality corresponding to the first reference signal resource on the first reference signal resource set being lower than the first threshold value includes: the wireless link quality corresponding to one or more or all of the first reference signal resources within the first reference signal set being lower than the first threshold value.

[0129] In some embodiments, the first information is used for link failure recovery or beam failure recovery of the first port.

[0130] In some embodiments, the name of the first information is not limited, which may, for example, be "failure recovery request information".

[0131] In some embodiments, the first information can be a first random access preamble, and the first information can be sent on a first random access channel occasion (RO), i.e., the first preamble is sent on the first RO.

[0132] In some embodiments, the first preamble and / or the first RO are determined in at least one of the following ways: a second random access preamble corresponding to a second reference signal resource is determined as the first random access preamble, the second reference signal resource being used to determine a new beam of the first port; a second random access opportunity corresponding to the second reference signal resource is determined as the first random access opportunity; a third random access preamble corresponding to a synchronization signal block is determined as the first random access preamble, the synchronization signal block corresponding to the second reference signal resource; a third random access opportunity corresponding to the synchronization signal block is determined as the first random access opportunity; a fourth random access preamble corresponding to the first port is determined as the first random access preamble; and a fourth random access opportunity corresponding to the first port is determined as the first random access opportunity.

[0133] Optionally, a second preamble corresponding to a second reference signal resource can be determined as the first preamble. The second reference signal resource is used to determine a new beam of the first port. For example, the terminal can determine a second reference signal resource set, and the second reference signal resource on the second reference signal resource set is used to determine a new beam corresponding to the first port. There is a mapping relationship between the second reference signal resource and the second preamble. The terminal can determine the second preamble corresponding to the second reference signal resource as the first preamble.

[0134] Optionally, a second RO corresponding to a second reference signal resource can be determined as the first RO. For example, there is a mapping relationship between the second reference signal resource and the second RO. The terminal can determine the second RO corresponding to the second reference signal resource as the first RO.

[0135] Optionally, a third preamble corresponding to a Synchronization Signal Block (SSB) corresponding to a second reference signal resource can be determined as the first preamble. For example, the second reference signal resource and the SSB are in a quasi co-location relationship, and the SSB is the SSB corresponding to the second reference signal resource. The terminal can determine the second preamble of the SSB corresponding to the second reference signal resource as the first preamble.

[0136] Optionally, a third RO corresponding to a SSB corresponding to a second reference signal can be determined as the first RO.

[0137] Optionally, the fourth preamble corresponding to the first port can be determined as the first preamble. For example, the first port and the fourth preamble have a mapping relationship. That is, different first ports can correspond to different fourth preambles. The fourth preamble corresponding to the first port can be determined as the first preamble.

[0138] Optionally, the fourth RO corresponding to the first port can be determined as the first RO.

[0139] In some embodiments, the mapping relationship described above can be configured by the network device or can be a default rule.

[0140] In some embodiments, if the terminal determines the fourth preamble as the first preamble, the fourth preamble can be a subset of the second preamble or a subset of the third preamble.

[0141] In some embodiments, if the terminal determines the fourth preamble as the first preamble. The fourth preamble can be a subset of the second preamble or a subset of the third preamble. That is, the preamble corresponding to the first port can be one or more of the preambles corresponding to the second reference signal resource. Or the preamble corresponding to the first port can be one or more of the preambles corresponding to the SSB, and the SSB is the SSB corresponding to the second reference signal resource.

[0142] For example, the third preambles corresponding to the second reference signal resource are M, but the M third preambles are for 2 first ports (e.g., first port A and first port B respectively) in one TRP (or panel), then the M third preambles can be divided into a first M / 2 third preambles and a second M / 2 third preambles. Among them, the first M / 2 third preambles can be used for the first port A, and the other second M / 2 third preambles are used for the first port B. If the wireless link quality corresponding to the first reference signal resource used for the first port A failure detection is lower than the first threshold value, the terminal can determine one from the first M / 2 third preambles as the first preamble, and send the first preamble for the link failure recovery or beam failure recovery of the first port A. The present disclosure does not enumerate one by one, but is not limited thereto, for example, the fourth preambles corresponding to the SSB (corresponding to the second reference signal resource) are M, but the M fourth preambles are for 2 first ports (e.g., first port A and first port B respectively) in one TRP (or panel), then the first M / 2 fourth preambles of the M fourth preambles can be used for the first port A, and the second M / 2 fourth preambles are used for the first port B. If the wireless link quality corresponding to the first reference signal resource used for the first port B failure detection is lower than the first threshold value, the terminal can determine one from the second M / 2 fourth preambles as the first preamble, and send the first preamble for the link failure recovery or beam failure recovery of the first port B.

[0143] In some embodiments, if the terminal determines the fourth RO as the first RO. The fourth RO can be a subset of the second RO, or a subset of the third RO. That is, the RO corresponding to the first port can be one or more of the RO corresponding to the second reference signal resource. Or the RO corresponding to the first port can be one or more of the RO corresponding to the SSB. Among them, the SSB is the SSB corresponding to the second reference signal resource.

[0144] For example, the third ROs corresponding to the second reference signal resources can be K, but the K third ROs are for 2 first ports (e.g., first port A and first port B respectively) of one TRP (or panel), then the first K / 2 third ROs among the K third ROs can be used for the first port A. And the other second K / 2 third ROs are used for the first port B. If the wireless link quality corresponding to the first reference signal resource used for the first port A failure detection is lower than the first threshold value, the terminal can determine one from the first K / 2 third ROs as the first RO, and send the first preamble on the first RO for the link failure recovery or beam failure recovery of the first port A. The disclosure does not enumerate all examples, but is not limited thereto. For example, the fourth ROs corresponding to the SSBs (the SSBs corresponding to the second reference signal resources) are K, but the K fourth ROs are for 2 first ports in one TRP (or panel), then the first K / 2 fourth ROs among the K fourth ROs can be used for the first port A, and the other second K / 2 fourth ROs are used for the first port B. If the wireless link quality corresponding to the first reference signal resource used for the first port B failure detection is lower than the first threshold value, the terminal can determine one from the second K / 2 fourth ROs as the first RO, and send the first preamble on the first RO for the link failure recovery or beam failure recovery of the first port B. M and K can be positive integers greater than or equal to 2.

[0145] It can be understood that the above examples of specific values are only exemplary, and the disclosure is not limited thereto.

[0150] In some embodiments, the first information can be UCI. The UCI can be UCI corresponding to the first port. Alternatively, the UCI can be UCI on a PUCCH resource corresponding to the first port.

[0151] In some embodiments, the PUCCH resource corresponding to the first port can be that a port corresponding to the PUCCH is the first port. Alternatively, the PUCCH resource can have a mapping relationship with the first port, and different first ports correspond to different PUCCH resources.

[0152] In some embodiments, the first information can be an UL MAC CE. The first information includes at least one of the following: an identifier of the first port; a cell identifier; an identifier of a first reference signal resource set; an identifier of a second reference signal resource set, the second reference signal resource set being used to determine a new beam of the first port; and an identifier of a second reference signal resource corresponding to the new beam.

[0153] In some embodiments, the identifier (Identity, ID) can also be an index (index).

[0154] In step S2103, the terminal 101 determines a second reference signal resource set.

[0155] In some embodiments, the second reference signal resource set is used to determine a new beam of the first port.

[0156] In some embodiments, the second reference signal resource set can be determined based on a configuration of the network device. For example, the network device configures the second reference signal resource set.

[0158] In some embodiments, the terminal can also determine the positions of a plurality of physical resource blocks (Physical Resource Block, PRB) of the first port.

[0159] In some embodiments, the first port can include a plurality of consecutive PRBs. The terminal can determine the positions of the plurality of PRBs so as to correspondingly use the corresponding TCI state to transmit or receive channels and / or signals on the corresponding frequency domain positions.

[0160] Step S2104, the terminal 101 selects a second reference signal resource from the second reference signal resource set, and determines the beam corresponding to the selected second reference signal resource as the new beam.

[0161] In some embodiments, the signal strength corresponding to the selected second reference signal resource is higher than a second threshold value. That is, the terminal selects a second reference signal resource with a signal strength higher than the second threshold value from the second reference signal resource set, and determines the beam corresponding thereto as the new beam.

[0162] In some embodiments, the signal strength may, for example, include but is not limited to at least one of the following: RSRP, RSRQ, and SINR.

[0163] In some embodiments, the size of the second threshold value is not limited, and the second threshold value and the first threshold value can be the same or different.

[0165] In some embodiments, the terminal 101 receives the second information sent by the network device 102.

[0166] In some embodiments, the second information is feedback information for the first information.

[0167] In some embodiments, the second information can be a PDCCH, and the Hybrid Automatic Repeat-reQuest processing number (HARQ processing number) of the Physical Uplink Shared Channel (PUSCH) scheduled by the second information and the PUSCH scheduled by the previous PDCCH can be the same, and the new data indication (NDI) can be flipped.

[0169] Step S2106, after receiving the second information, the terminal 101 transmits on the first port based on the new beam for N symbols.

[0170] In some embodiments, after receiving the second information, the terminal 101 transmits at least one of the following on the first port based on the quasi co-location parameter or the spatial relation information or the spatial domain filter corresponding to the new beam after N symbols: PDCCH; PUSCH; PUCCH; PDSCH.
