As shown in FIG. 1b, for a UE in the far field, the electromagnetic wave received by the UE from different antenna ports or elements is a plane wave, and the beam for the UE is a two-dimensional (2dimension, 2D) directional beam pointing to the target UE. For any path in multipath propagation, the time and phase of arrival at the UE receiving antenna array are equally spaced.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] Therefore, the present disclosure provides a communication method, by determining a first reference signal resource set, so that a failure detection is performed for a first port, so as to facilitate a link failure recovery or a beam failure recovery based on the first port, thereby improving communication efficiency.

[0132] 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:

[0133] At step S2101, the terminal 101 determines a first reference signal resource set.

[0134] In some embodiments, the first reference signal resource set is used for failure detection of a first port.

[0135] In some embodiments, the first port can be one or more. For example, when the first port is multiple, the terminal can determine a first reference signal resource set for each first port respectively. The multiple first ports can be different ports of a same TRP / panel.

[0136] In some embodiments, the failure detection can be, for example, a link failure detection, or a beam failure detection.

[0137] In some embodiments, the first reference signal resource set can be determined based on a Transmission Configuration Indicator state (TCI state).

[0138] In some embodiments, the TCI state used for determining the first reference signal resource set can include at least one of: a first TCI state corresponding to a control resource set (CORESET); an indicated TCI state.

[0139] In some embodiments, the terminal can receive first information sent by the network device, the first information being used for indicating the first TCI state corresponding to the CORESET. The terminal can determine at least one reference signal resource in the first reference signal resource set based on the first TCI state indicated by the first information.

[0140] In some embodiments, the terminal can receive second information sent by the network device, the second information being used for indicating the indicated TCI state. The terminal can determine at least one reference signal resource in the first reference signal resource set based on the indicated TCI state indicated by the second information.

[0141] In some embodiments, the terminal can receive the first information and the second information sent by the network device, and determine a first reference signal resource in the first reference signal resource set based on the first TCI state corresponding to the CORESET indicated by the first information and the indicated TCI state indicated by the second information. For example, the first TCI state can determine a part of the first reference signal resources in the first reference signal resource set. The indicated TCI state can determine another part of the first reference signal resources in the first reference signal resource set.

[0142] In some embodiments, the second information comprises at least one of: a medium access control control element (MAC CE) used to activate an indicated TCI state corresponding to one codepoint or indicated TCI states corresponding to multiple codepoints respectively, the one codepoint or multiple codepoints corresponding to an indication field of a downlink control information (DCI); and the DCI, the indication field of the DCI used to indicate one of the multiple codepoints activated by the MAC CE.

[0143] Optionally, the indication field of the DCI can comprise at least one codepoint, each codepoint corresponding to one indicated TCI state. The MAC CE can activate the indicated TCI state corresponding to one codepoint corresponding to the indication field of the DCI. The activated indicated TCI state can be used to determine at least one reference signal resource in the first reference signal resource set.

[0144] Optionally, the indication field of the DCI can comprise at least one codepoint, each codepoint corresponding to one indicated TCI state. The MAC CE can activate the indicated TCI state corresponding to one codepoint corresponding to the indication field of the DCI. The activated indicated TCI state can be used to determine at least one reference signal resource in the first reference signal resource set.

[0145] In some embodiments, the control resource set can be a control resource set following an indicated Transmission Configuration Indicator state (indicated TCI state), or a control resource set not following the indicated TCI state. It can be understood that, if the control resource set is a control resource set following the indicated TCI state, the first reference signal resource determined by the first TCI state corresponding to the control resource set and the first reference signal resource determined by the indicated TCI state can be the same. That is, if the TCI state used to determine the first reference signal resource set is the first TCI state corresponding to the control resource set, and the control resource set is a control resource set following the indicated TCI state, the first reference signal resource set determined based on the first TCI state includes the reference signal resource corresponding to the indicated TCI state.

[0146] In some embodiments, the port corresponding to the PDCCH on the control resource set includes a first port. For example, the terminal can determine, according to the PDCCH on the first port corresponding to the control resource set and based on the first TCI state corresponding to the control resource set, the first reference signal resource set for failed detection of the first port.

[0147] In some embodiments, the port information included in the first TCI state includes the first port. For example, the terminal can determine, according to the port information included in the first TCI state corresponding to the first port and based on the first TCI state, the first reference signal resource set for failed detection of the first port.

[0148] In some embodiments, the number of control resource sets can be multiple. For example, the ports corresponding to the PDCCH on the multiple control resource sets all include the first port. Alternatively, the port information included in the TCI states corresponding to the multiple control resource sets all correspond to the first port. The first TCI state can include the TCI state corresponding to at least one of the multiple control resource sets. The number of first TCI states can also be multiple.

[0149] In some embodiments, if the number of control resource sets can be multiple, the control resource sets have priorities. For example, the terminal can select, according to the priorities of the control resource sets, the TCI state corresponding to at least one of the control resource sets to determine the first reference signal resource set.

[0150] In some embodiments, the at least one control resource set corresponds to one or more TCI states. For example, when the control resource set is one, the corresponding TCI state can be one or more. When the control resource set is multiple, the multiple control resource sets correspond to multiple TCI states, and different control resource sets can correspond to one or more TCI states respectively. For example, in the multiple TCI states corresponding to the multiple control resource sets, each TCI state can correspond to a different control resource set, some TCI states can correspond to the same control resource set, or different control resource sets can correspond to the same TCI state.

[0151] In some embodiments, the first TCI state includes a TCI state corresponding to at least one control resource set with a high priority. For example, the TCI state corresponding to one or more control resource sets with the highest priority can be selected to determine at least one first reference signal resource in the first reference signal resource set. Or the TCI state corresponding to the control resource set with the second highest priority can be selected to determine at least one first reference signal resource in the first reference signal resource set. The second highest priority can be understood as only second to the highest priority. That is, the control resource set with the second highest priority can be lower in priority than the control resource set with the highest priority, but higher in priority than other control resource sets.

[0152] For example, assuming there are multiple control resource sets, the priority order is A, B, C, D, and E respectively. That is, the priority of control resource set A is higher than that of control resource set B, the priority of control resource set B is higher than that of control resource set C, and so on. The at least one control resource set with a high priority can be one or more control resource sets with the highest priority, for example, it can be one control resource set with the highest priority, i.e., control resource set A. For another example, it can be two control resource sets with the highest priority, i.e., control resource sets A and B. For another example, it can be one control resource set with the second highest priority, i.e., control resource set B. For another example, it can be two control resource sets with the second highest priority, i.e., control resource sets B and C.

[0153] For example, assume there are multiple control resource sets, and their priority order is A, B, C, D, E. Control resource set A and control resource set B have the same priority, which is higher than the priority of control resource set C. The priority of control resource set C is higher than the priority of control resource set D, and so on. At this time, the control resource set with the highest priority can be selected, for example, control resource set A and control resource set B can be selected. Alternatively, one of control resource set A and B can be selected, and the TCI state corresponding to the selected control resource set can be used as the first TCI state for determining at least one first reference signal resource in the first reference signal resource set.

[0154] It can be understood that the examples of the "control resource set with high priority" in the disclosure are not limited to the above exemplary cases. For example, in the control resource sets with priority order A, B, C, D, E, control resource set D can be selected as the control resource set with high priority, and the TCI state corresponding to control resource set D can be used as the first TCI state. In different embodiments, in order to cope with different scenarios, the actual selected control resource set can be different, but the first TCI state determined by the control resource set with higher priority can be better used to determine at least one first reference signal resource in the first reference signal resource set, thereby improving the communication efficiency and the success rate and accuracy of failure detection.

[0155] In some embodiments, the priority of the control resource set is determined in at least one of the following ways: among the multiple control resource sets, the control resource set with a smaller period of the associated search space set has a higher priority; among the multiple control resource sets, the control resource set with a larger index has a higher priority; among the multiple control resource sets, the control resource set following the indicated TCI state has a higher priority than the control resource set not following the indicated TCI state.

[0156] In some embodiments, when the number of control resource sets is greater than the number of reference signal resources in the first reference signal resource set supported by the terminal, or the number of TCI states corresponding to the control resource sets is greater than the number of reference signal resources in the first reference signal resource set supported by the terminal, it is necessary to determine which reference signal resources in the TCI states corresponding to the control resource sets can be included in the first reference signal resource set based on the priority of the control resource set.

[0157] Optionally, the control resource set can be associated with a search space set. The smaller the period of the associated search space set, the higher the priority of the control resource set.

[0158] Optionally, different control resource sets can correspond to different indexes. The larger the index of a control resource set, the higher the priority. The indexes corresponding to different control resource sets may, for example, be #0, #1, #2, and so on. Of course, it can also be that the smaller the index of a control resource set, the higher the priority, which is not limited in the present disclosure. The index can also be referred to as an identity (ID) or index.

[0159] Optionally, the control resource set can be a control resource set following the indicated TCI state, or a control resource set not following the indicated TCI state. The control resource set following the indicated TCI state has a higher priority than the control resource set not following the indicated TCI state.

[0160] In some embodiments, the indicated TCI state is a first indicated TCI state corresponding to a first port.

[0161] In some embodiments, the indicated TCI state is used for transmission of a plurality of channels / signals, the channels including at least one of the following: a physical downlink control channel (PDCCH); a physical downlink shared channel (PDSCH); a physical uplink control channel (PUCCH); a physical uplink shared channel (PUSCH); and the signals including at least one of the following: a channel state information-reference signal (CSI-RS); a sounding reference signal (SRS).

[0162] In some embodiments, the CSI-RS may, for example, be aperiodic (aperiodic).

[0163] In some embodiments, the SRS may, for example, be aperiodic (aperiodic).

[0164] In some embodiments, the indicated TCI state includes at least one of the following: a second TCI state of a downlink; a joint second TCI state.

[0165] In some embodiments, the TCI state can include the indicated TCI state; or, the TCI state includes the indicated TCI state and a first TCI state corresponding to a control resource set not following the indicated TCI state.

[0166] In some embodiments, if the TCI state includes an indicated TCI state, and a first TCI state corresponding to a control resource set not following the indicated TCI state, the priority of the indicated TCI state is higher than the first TCI state corresponding to the control resource set not following the indicated TCI state.

[0167] In some embodiments, the indicated TCI state indicates multiple quasi-co-location types, and a first reference signal resource on the first reference signal resource set is a reference signal resource corresponding to quasi-co-location type D in the indicated TCI state; wherein the quasi-co-location type D is used to indicate a spatial reception parameter.

[0168] 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.

[0169] Step S2102, the terminal 101 determines a second reference signal resource set.

[0170] In some embodiments, the second reference signal resource set is used to determine a new beam of the first port.

[0171] In some embodiments, the second reference signal resource set can be determined based on the configuration of the network device. For example, the network device configures the second reference signal resource set.

[0172] In some embodiments, the new beam can also be referred to as a candidate beam, or a target beam.

[0173] In some embodiments, the terminal can also determine the location of multiple physical resource blocks (PRBs) of the first port.

[0174] In some embodiments, the first port can include multiple consecutive PRBs. The terminal can determine the location of the multiple PRBs so as to correspondingly use the corresponding TCI state to transmit or receive channels and / or signals on the corresponding frequency domain locations.

[0175] Step S2103, 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 a new beam.

[0176] In some embodiments, the selected second reference signal resource corresponds to a signal strength higher than a second threshold value. That is, the terminal selects, from the second reference signal resource set, a second reference signal resource corresponding to a signal strength higher than the second threshold value, and determines the beam corresponding to the second reference signal resource as the new beam.

[0177] 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.

[0178] In some embodiments, the size of the second threshold value is not limited, and the second threshold value and the first threshold value may, for example, be the same or different.

[0179] In step S2104, the network device 102 sends third information to the terminal 101.

[0180] In some embodiments, the terminal 101 receives the third information sent by the network device 102.

[0181] In some embodiments, the third information is feedback information for fourth information. The fourth information may, for example, be sent by the terminal 101 to the network device 102 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 fourth information is used for link failure recovery or beam failure recovery of the first port.

[0182] In some embodiments, the third information may, for example, be a PDCCH, the physical uplink shared channel (PUSCH) scheduled by the third information, and the hybrid automatic repeat-reQuest processing number (HARQ processing number) of the PUSCH scheduled by the previous PDCCH may, for example, be the same, and the new data indication (NDI) may, for example, be flipped.

[0183] 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 send the fourth information to the network device if it detects 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 size of the first threshold value is not limited by the present disclosure.

[0184] 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 that the wireless link quality corresponding to one or more or all of the first reference signal resources in the first reference signal set is lower than the first threshold value.

[0185] In some embodiments, the name of the fourth information and the third information is not limited, and the fourth information may, for example, be "failure recovery request information". The third information may, for example, be "feedback information", "PDCCH", etc., and the present disclosure does not limit.

[0186] In step S2105, the terminal 101 transmits based on the new beam on the first port after receiving the third information for N symbols.

[0187] In some embodiments, after receiving the third 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 relationship information or the spatial domain filter corresponding to the new beam for N symbols: PDCCH; PDSCH; Physical Uplink Control Channel (PUCCH); Physical Uplink Shared Channel (PUSCH).

[0188] In some embodiments, the quasi co-location parameters include at least one of the following types: Type A, which is used to indicate Doppler shift, Doppler spread, average delay, delay spread; Type B, which is used to indicate Doppler shift, Doppler spread; Type C, which is used to indicate Doppler shift, average delay; Type D, which is used to indicate spatial reception parameters; power control parameters. Each type corresponds to a reference signal resource identifier. The reference signal resource identifiers corresponding to different types can be the same or different.

[0189] In some embodiments, the beam can be referred to as a spatial reception parameter (spatial Rx parameter), a quasi-co location (QCL) Type D, a spatial setting, a spatial reception filter, a spatial transmission filter, a spatial domain filter, a TCI state, an indicated TCI state, a joint TCI state, a downlink TCI state (DL TCI state), an uplink TCI state (UL TCI state), a unified TCI state, a common TCI state, spatial relation information (spatialrelationinfo), etc.

[0190] In some embodiments, a symbol is a unit of time domain. N can be determined according to actual conditions, and the present disclosure is not limited. The symbol length can be determined based on the specified subcarrier space (SCS).

[0191] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2105. For example, step S2101 can be implemented as an independent embodiment, but is not limited thereto.
