Further, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0138] In some embodiments, with the continuous development of wireless communication technology, in the Multiple Input Multiple Output (MIMO) technology of the 6th generation mobile communication system (6G), in order to provide higher spectrum efficiency, high frequency bands and large-scale antenna arrays are introduced. Large-scale antennas can provide larger beamforming gain, effectively compensating for the transmission loss of high frequency bands.

[0139] For a given antenna array (whose antenna aperture is denoted as D), its electromagnetic (EM) field can be divided into a near field and a far field, as shown in FIG. 1B. The boundary between the near field and the far field is called the Rayleigh distance. The size of the near field depends on the antenna aperture (D) and the wavelength (λ).

[0140] In some embodiments, for a UE in the far field, the electromagnetic waves received by the UE from different antenna ports or elements are plane waves, and the beam for the UE is a 2dimension (2D) directional beam pointing to the target UE. For any path in multipath propagation, the time and phase of arrival at the UE's receiving antenna array are equally spaced, as shown in FIG. 1C(a).

[0141] In some embodiments, if the UE is in the near field, the electromagnetic waves received by the UE are spherical waves, and the beam for the UE is a 3dimension (3D) beam surrounding the target UE. For any path in multipath propagation, the time and phase of arrival at the UE's receiving antenna array are no longer equally spaced, as shown in FIG. 1C(b). When the UE is in the near field, as described above, for any path in multipath propagation, the time and phase of arrival at the UE's receiving antenna array are no longer equally spaced.

[0142] ​That is, for far field terminals, multiple ports arrive at the terminal in the same direction. For near field terminals, the beam direction of different ports arriving at the terminal is different. Therefore, like traditional beam management, if the base station has 32 transmission beam directions, it only needs to send 32 reference signals based on 32 beam directions at any one port. However, for near field terminals, the distance of the first beam direction transmitted by the base station at the first port and the first beam direction transmitted by the base station at the second port arriving at the terminal is not the same. Therefore, the base station needs to send reference signals based on 32 beam directions at each port. If the base station still transmits reference signals for beam measurement in the traditional single-port manner, the terminal scanning time will increase by a multiple of the number of ports.

[0143] Furthermore, for terminals, high frequency bands make beams narrower and the number of beams larger, and how to reduce beam scanning time and enable terminals in each beam coverage range to obtain services as soon as possible is a problem to be solved.

[0144] In some embodiments, the base station can transmit a channel state information reference signal (CSI-RS) associated with a synchronization signal block (SSB), where the CSI-RS associated with one SSB can be used for the base station to transmit in different transmission beam directions. However, how to inform the UE of the information of the CSI-RS resource is also a problem to be solved.

[0145] In some embodiments, each SSB corresponds to a different SSB index, and the SSB index corresponds to a different transmission time, and the terminal can obtain downlink synchronization based on the SSB index.

[0146] In some embodiments, for example, as shown in FIG. 1D, each synchronization signal block (SSB) can occupy 4 consecutive symbols, in order, each symbol respectively for a primary synchronization signal (PSS), a physical broadcast channel (PBCH), a secondary synchronization signal (SSS) + PBCH (the middle 12 resource blocks (RBs) in the frequency domain are SSS, and the two sides each have 4 RBs for PBCH, that is, the SSB occupies 20 RBs in the frequency domain), and a PBCH, where some sub-carriers in the PBCH are demodulation reference signals (DMRS). The sub-carrier spacing (SCS) of the synchronization signal block can be 15KHz, 30KHz, 120KHz, and 240KHz. All synchronization signal blocks are transmitted within 5ms. In order to support beam transmission, each beam needs to transmit an SSB when there is a beam, so the maximum number of synchronization signal blocks that can be transmitted within 5ms is 4 (when the carrier frequency is below 3GHz), or 8 (when the carrier frequency is 3GHz-7GHz), or 64 (when the carrier frequency is above 7GHz), and the multiple SSBs within the 5ms are referred to as an SSB burst set. The period of the SSB burst set can be 5ms, 10ms, 20ms, 40ms, etc.

[0147] In some embodiments, in the above example, for the terminal, after the terminal receives the SSB, obtains the SSB index from the DMRS sequence in the SSB or from the DMRS sequence and the payload in the PBCH, the time domain position corresponding to the SSB, that is, which symbol in which slot within 5ms, is obtained, that is, downlink synchronization is achieved.

[0164] In some embodiments, the first reference signals on the first reference signal resources have a Quasi Co-location (QCL) relationship with the second reference signals on the second reference signal resources.

[0165] Optionally, since the first reference signals and the second reference signals have the QCL relationship, the terminal 101 can not switch the reception beam when receiving the second reference signals and the first reference signals. The first reference signal resources corresponding to the first reference signals are associated with the second reference signal resources corresponding to the second reference signals.

[0186] In some embodiments, the protocol can specify the maximum number of the first reference signal resources associated with one second reference signal resource based on different frequency bands.

The terminal 101 can perform the reception of the first reference signal on at least one of the number of the first reference signal resources indicated by the first information.

The terminal 101 can perform the reception of the first reference signal on at least one of the number of ports indicated by the first information.

The terminal 101 can perform the reception of the first reference signal on at least one of the number of port groups indicated by the first information.

[0193] In some embodiments, the terminal 101 can also receive the first information sent by the network device 102, the first information being used for indicating candidate values of the number of the first reference signal resources (as an example, the first information is used for indicating candidate values 2, 4, 8, 12, 16, …). The terminal 101 can determine the number of the first reference signal resources from the candidate values indicated by the first information.

[0194] In some embodiments, the terminal 101 can also receive the first information sent by the network device 102, the first information being used for indicating candidate values of the number of ports included in the first reference signal resource. The terminal 101 can determine the number of ports included in the first reference signal resource from the candidate values indicated by the first information.

[0195] In some embodiments, for the case that one first reference signal resource is associated with one second reference signal resource and the first reference signal resource includes multiple ports, the number of ports included in the first reference signal resource can be determined based on any of the above embodiments. Further, the terminal 101 can determine other parameters (e.g. port ID, density, CDM type, subcarrier location, index of CDM group, etc.) of the first reference signal resource corresponding to the determined number of ports based on the determined number of ports. As an example, the terminal 101 can select other parameters of the first row in at least one row corresponding to the determined number of ports in the protocol specified table of first reference signal resource parameters by default.

Further, the terminal 101 can determine other parameters (e.g. port ID, density, CDM type, subcarrier location, index of CDM group, etc.) of the first reference signal resource with one port.

[0200] As an example, the terminal 101 can select other parameters in a row with port number 1 in a first reference signal resource parameter table specified by the protocol, such as the first row or the second row in Table 1. For example, the terminal selects other parameters in the first row in Table 1, each first reference signal occupies 3 subcarriers in one symbol, because one RB includes 12 subcarriers, 4 first reference signals (each first reference signal occupies 3 out of 12 subcarriers in a comb shape) can be transmitted in one symbol at the same time, and the first reference signals can be numbered based on the subcarrier position. For example, the ID of the first reference signal occupying the first subcarrier (occupying the 1st, 5th, and 9th subcarriers) is #0, the ID of the first reference signal occupying the second subcarrier (occupying the 2nd, 6th, and 10th subcarriers) is #1, and so on.

[0227] In the foregoing various embodiments, the time-domain position of the at least one first reference signal resource associated with the second reference signal resource satisfies at least one of the following conditions:

[0228] The time-domain symbol where the first reference signal resource is located is the nearest free symbol to the time-domain symbol where the second reference signal resource is located;

[0229] The time-domain symbol where the first reference signal resource is located is adjacent to (i.e., with an interval of 0 time-domain symbols) the time-domain symbol where the second reference signal resource is located;

[0230] The time-domain symbol where the first reference signal resource is located is spaced apart from the time-domain symbol where the second reference signal resource is located by N time-domain symbols, where N is a non-negative integer;

[0231] The time-domain symbol where the first reference signal resource is located is different from the time-domain symbol where the second reference signal resource is located by M time-domain symbols, where M is a non-negative integer;

[0233] The time-domain symbol where the first reference signal resource is located is in adjacent two slots as the time-domain symbol where the second reference signal resource is located;

[0234] The time-domain symbol where the first reference signal resource is located is in adjacent four slots as the time-domain symbol where the second reference signal resource is located.

[0235] Optionally, when N is 0, the time-domain symbol where the first reference signal resource is located is spaced apart from the time-domain symbol where the second reference signal resource is located by 0 time-domain symbols, i.e., the time-domain symbol where the first reference signal resource is located is adjacent to the time-domain symbol where the second reference signal resource is located.

[0236] Optionally, when M is 0, the time-domain symbol where the first reference signal resource is located is different from the time-domain symbol where the second reference signal resource is located by 0 time-domain symbols, i.e., the first reference signal resource and the second reference signal resource occupy the same time-domain symbol, i.e., the first reference signal and the second reference signal are frequency division multiplexed (FDM).

[0237] In some embodiments, the first reference signal resource and the second reference signal resource occupy different time domain symbols (i.e., the first reference signal and the second reference signal can be Time Division Multiplexing (TDM)).

[0238] In some embodiments, the first reference signal resource and the second reference signal resource occupy different frequency domain resources, and the first reference signal resource and the second reference signal occupy the same time domain symbol (i.e., the first reference signal and the second reference signal can be Frequency Division Multiplexing (FDM)).

[0239] In some embodiments, the first reference signal resource and the control resource set CORESET#0 occupy the same time domain symbol.

[0240] In some embodiments, the first reference signal resource and the system information block SIB occupy the same time domain symbol (i.e., the first reference signal and the PDSCH scheduled by the DCI in CORESET#0 are Frequency Division Multiplexing (FDM)).

[0241] As an example, when the subcarrier spacing is 15KHz, or the subcarrier spacing is 30KHz and the time domain distribution 1, the time domain position of the second reference signal with index 0 is symbols 2-5, and the time domain position of the first reference signal resource associated with the second reference signal resource can be at least one of symbols 0, 1, 6, 7, and 12, 13 is also possible; and the time domain position of the second reference signal with index 1 is symbols 8-11, and the time domain position of the first reference signal resource associated with the second reference signal resource can be at least one of symbols 6, 7, 12, 13, and 0, 1 is also possible. In this case, the first reference signal resource and the second reference signal resource are in the same time slot as much as possible.

[0242] As an example, when the subcarrier spacing is 30KHz, the time domain distribution 2, or when the subcarrier spacing is 120KHz, the time domain location of the second reference signal resource is: occupying symbol 4~7, symbol 8~11, symbol 16~19 and symbol 20~23 in every 28 symbols. While when the subcarrier spacing is 30KHz, the number of the second reference signal is maximum 4 or 8, i.e. the starting position of each second reference signal is {4, 8, 16, 20}+28*n, n is 0 or n is 0, 1. In this case, the time domain location of the second reference signal with index 0 is symbol 4~7, then the time domain location of the first reference signal resource associated with this second reference signal resource can be at least one of symbol 0, 1, 2, 3, of course 12, 13 is also possible; while the time domain location of the second reference signal with index 1 is symbol 8~11, then the time domain location of the first reference signal resource associated with this second reference signal resource can be at least one of symbol 12, 13, 14, 15 (i.e. symbol 0, 1 of the next slot), of course 0, 1, 2, 3 of the current slot is also possible. In this case, the first reference signal resource and the second reference signal resource are as far as possible in one or two adjacent slots.

[0243] As an example, when the subcarrier spacing is 240 KHz, the time domain location of the second reference signal resource is: occupying symbol 8~11, symbol 12~15, symbol 16~19, symbol 20~23, symbol 32~35, symbol 36~39, symbol 40~43 and symbol 44~47 in every 56 symbols. And when the subcarrier spacing is 240 KHz, the number of the second reference signal is maximum 64, i.e. the starting position of each second reference signal is {8, 12, 16, 20, 32, 36, 40, 44}+56*n, n is n=0, 1, 2, 3, 5, 6, 7, 8. In this case, 4 slots 56 symbols, the time domain location of the second reference signal with index 0 is symbol 8~11, the time domain location of the second reference signal with index 1 is symbol 12~15, the time domain location of the second reference signal with index 2 is symbol 16~19, the time domain location of the second reference signal with index 3 is symbol 20~23, the time domain location of the second reference signal with index 4 is symbol 32~35, and the time domain location of the second reference signal with index 5 is symbol 36~39, the time domain location of the second reference signal with index 6 is symbol 40~43, and the time domain location of the second reference signal with index 7 is symbol 44~47. Then, the time domain location of the first reference signal resource associated with the second reference signal with index #0 and #1 can be at least one of symbol 0, 1, 2, 3, 4, 5, 6, 7, of course 24, 25, 26, 27, 28, 29, 30, 31 are also possible; and the time domain location of the first reference signal resource associated with the second reference signal with index #2 and #3 can be at least one of symbol 24, 25, 26, 27, 28, 29, 30, 31, of course 0, 1, 2, 3, 4, 5, 6, 7 are also possible; and the time domain location of the first reference signal resource associated with the second reference signal with index #4 and #5 can be at least one of symbol 24, 25, 26, 27, 28, 29, 30, 31, of course 48, 49, 50, 51 are also possible. And the time domain location of the first reference signal resource associated with the second reference signal with index #6 and #7 can be at least one of symbol 48, 49, 50, 51, of course 24, 25, 26, 27, 28, 29, 30, 31 are also possible. In this case, the first reference signal resource and the second reference signal resource are as far as possible in one or two or four adjacent slots.

[0244] It can be understood that, in the above examples, the time domain position where the second reference signal resource is located is only given as an example, and the time domain position where the second reference signal resource is located can also be other cases, which are not limited herein by the embodiments of the present application. In addition, in the above examples, the time domain position where the first reference signal resource is located is also only given as an example, and the time domain position where the first reference signal resource is located can also be other cases, which are not limited herein by the embodiments of the present application.
