It should be noted that the user equipment (UE) in the present disclosure may be a terminal, and it can be understood that the terminal in the present disclosure may be considered as the user equipment.

[0029] Here, the user equipment 110 may be equipment that provides voice and / or data connectivity to a user.

[0036] The multiple base stations 120 are each connected to a network management device 130.

[0037] In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure will enumerate several embodiments to clearly explain the technical solutions of the embodiments of the present disclosure.Of course, as can be understood by those skilled in the art, the several embodiments provided by the embodiments of the present disclosure can be implemented alone, can be implemented in combination with the methods of other embodiments in the embodiments of the present disclosure, and can be implemented alone or in combination with some methods in other related technologies, and the embodiments of the present disclosure are not limited thereto.

[0038] To better understand the embodiments of the present disclosure, a related scenario is exemplarily described below.

[0039] In one scenario embodiment, the terminal and / or base station supports multi-TRP transmission of two TRPs.

[0040] In one embodiment, the base station needs to receive the transmission signals of multiple terminals in the same uplink time slot. The distances from each terminal to the base station can vary significantly, and the signal fading also differs depending on the positions of the terminals. Therefore, it is necessary to introduce timing advance (TA). That is, each terminal should correspond to one base station and have one specific timing advance TA. Different terminals need to perform uplink transmission using different timing advances TA based on their distances to the base station, ensuring that the signals of different terminals arrive at the base station side basically at the same time.

[0041] In one embodiment, in the mode of M-DCI, the TAs of two TRPs are the same. In this way, the time difference between the two transmission signals of the terminal is 0, ensuring the low complexity realized by the terminal. However, the requirement of the same TA restricts the flexibility of base station deployment.

[0042] In one embodiment, the timing advance value of base station 1 is TA1, and the timing advance value of base station 2 is TA2. The timing advances of the two transmission links of the terminal have a time difference of △T = TA1 - TA2. The maximum transmit time difference (MTTD, Maximum transmit Timing Difference) that the terminal can support restricts the multi-TRP transmission ability of the base station in this case. That is, when the timing advance difference value △T between the two TRPs is less than MTTD, the corresponding multi-TRP M-DCI transmission can be carried out. When △T > MTTD, the multi-TRP M-DCI transmission cannot be carried out. Regarding the MTTD requirement in the case of multi-TRP M-DCI, it is not yet clear in the related art. Therefore, the base station cannot determine the operation status of multi-TRP M-DCI based on △T. The present invention clarifies the MTTD requirement of the terminal by means of a predetermined value and / or the method of terminal capability reporting, thereby ensuring that the base station schedules the multi-TRP M-DCI transmission of the terminal based on the corresponding MTTD.

[0043] Note that when considering MTTD, what is actually being considered is the difference in distance of the terminal to two different base stations, which is in turn reflected in the Maximum Receive Timing difference (MRTD), so MRTD and MTTD are directly related.

[0044] In one embodiment, for base stations from different locations, the terminal needs to receive downlink transmission signals from different base stations as close to the same time as possible, thereby ensuring simultaneous processing of corresponding transmission signals and reducing the complexity of signal processing by the terminal. Generally, it is considered that, for the terminal's receiving capabilities, the signal time difference between two base stations arriving at the terminal needs to be smaller than the cyclic prefix (CP), so that the terminal can complete processing for two arriving signals within one fast Fourier transform (FFT) window, thereby maintaining the processing complexity and processing delay of the terminal's receiving side. Therefore, when considering the receive timing difference (RTD), a distinction is made between those greater than CP and those less than CP. Similarly, when considering MTTD, a distinction is made between those greater than CP and those less than CP, which is reflected in the subsequent solution.

[0045] As shown in FIG. 2 , this embodiment provides a method for scheduling mTRP transmission, where the method is performed by an access network device, and the method includes: It includes a step 21 of determining terminal capability information.

[0046] Here, the terminal capability information is used to schedule the transmission operation of multi-downlink control information M-DCI of the multi-transmission reception point mTRP of the terminal.

[0047] Here, the terminal according to the present disclosure may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle device, a roadside unit (RSU), a smart home device, an industrial sensing device, and / or a medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a certain version of a New Radio NR terminal (e.g., an R17 NR terminal).

[0048] Here, the access network device according to the present disclosure may be a base station of various types, for example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

[0049] Exemplarily, scheduling a transmission operation of multi-downlink control information M-DCI of a multi-transmission reception point mTRP of the terminal may include scheduling transmission of multi-downlink control information M-DCI of a multi-transmission reception point mTRP of the terminal, or not scheduling transmission of multi-downlink control information M-DCI of a multi-transmission reception point mTRP of the terminal.

[0050] In one embodiment, the terminal capability information may be MTTD between the terminal and different TRPs.

[0051] In one embodiment, a maximum transmission time difference (MTTD) supported by the terminal is determined, and the MTTD is used to schedule transmission operations of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal.

[0052] In one embodiment, the maximum transmission time difference (MTTD) supported by the terminal is determined, and based on the MTTD, it is determined whether to schedule transmission of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal.

[0053] In one embodiment, the terminal determines a maximum transmission time difference (MTTD) supported by the terminal, and schedules the transmission operation of the M-DCI of the mTRP of the terminal based on the difference between the MTTD and the timing advance (TA) of the mTRP.

[0054] In one embodiment, a maximum transmission time difference (MTTD) supported by a terminal is determined, and in response to a difference in timing advance (TA) between the MTTD and the TRP being equal to or less than the MTTD, transmission of an M-DCI in an mTRP of the terminal is scheduled, or in response to a difference in timing advance (TA) between the MTTD and the TRP being equal to or greater than the MTTD, transmission of an M-DCI in an mTRP of the terminal is not scheduled.

[0055] In one embodiment, the MTTD supported by the terminal is determined based on predetermined configuration information, and transmission operations of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal are scheduled based on the MTTD.

[0056] In one embodiment, the MTTD supported by the terminal is determined based on predetermined configuration information that has been set in advance, and transmission operations of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal are scheduled based on the MTTD.

[0057] In one embodiment, the MTTD supported by the terminal is determined based on predetermined configuration information determined by a predetermined protocol rule, and transmission operations of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal are scheduled based on the MTTD.

[0058] In one embodiment, the MTTD supported by the terminal is determined based on predetermined configuration information, reception time difference RTD, and cyclic prefix CP, and transmission operations of multi-downlink control information M-DCI of multi-transmission reception points mTRP of the terminal are scheduled based on the MTTD.

[0059] The predetermined protocol rule may be a communication rule for wireless communication between the terminal and the access network device. The predetermined protocol rule may be agreed upon in advance. The terminal and the access network device may perform wireless communication with each other based on the agreed upon predetermined protocol rule.

[0060] In one embodiment, the predetermined configuration information includes first predetermined configuration information and second predetermined configuration information. In response to the RTD being equal to or greater than the CP, the MTTD is determined based on the first predetermined configuration information. Based on the MTTD, a transmission operation of multiple downlink control information (M-DCI) of a multiple transmission reception point (mTRP) of the terminal is scheduled.

[0061] In one embodiment, the predetermined configuration information includes first predetermined configuration information and second predetermined configuration information. In response to the RTD being less than or equal to the CP, the MTTD is determined based on the second predetermined configuration information. Based on the MTTD, a transmission operation of multiple downlink control information (M-DCI) of a multiple transmission reception point (mTRP) of the terminal is scheduled.

[0062] In one embodiment, the predetermined configuration information includes first predetermined configuration information and second predetermined configuration information. In response to the RTD being equal to or greater than the CP, the MTTD is determined based on the first predetermined configuration information, or in response to the RTD being equal to or less than the CP, the MTTD is determined based on the second predetermined configuration information. Based on the MTTD, a transmission operation of multiple downlink control information (M-DCI) of a multiple transmission reception point (mTRP) of the terminal is scheduled. The first predetermined configuration information indicates a mapping relationship between a frequency range and the MTTD, and the second predetermined configuration information indicates a mapping relationship between a frequency range, a predetermined value, and a cyclic prefix (CP), the predetermined value and the cyclic prefix being used to determine the corresponding MTTD.

[0063] For example, see Table 1, which shows the mapping relationship between frequency ranges and MTTD.

[0064] [Table 1]

[0065] Note that the mapping relationship may be a relationship between an inter-band carrier aggregation (CA) frequency range and MTTD.

[0066] For example, refer to Table 2, which shows the mapping relationship between frequency ranges, predetermined values, and cyclic prefixes CP.

[0067] [Table 2]

[0068] where M1 and M2 are predetermined values, and values ​​consistent with the CA scene can be used, i.e., M1=1.6 μs, M2=0.5 μs.

[0069] As can be understood, each element in the tables (Table 1 and Table 2) exists independently, and although these elements are illustratively listed in the same table, this does not mean that all elements in the tables must exist simultaneously as shown in the tables. Here, the value of each element does not depend on the value of any other element in the table. Therefore, as can be understood by those skilled in the art, the value of each element in the table is an independent embodiment.

[0070] The terminal and / or network device must operate within a certain frequency range (FR), where FR1 may be a frequency range of 450 MHz to 6 GHz, and FR2 may be a frequency range of 24 GHz to 52 GHz. Here, FR2-1 may be a sub-range further divided from the FR2 frequency range, for example, a range corresponding to 24,250 to 27,500 MHz corresponding to frequency band n285.

[0071] In the above example, the mapping relationship may be agreed upon in advance, and the agreed mapping relationship may be pre-stored in the access network device for retrieval. In one embodiment, the predetermined configuration information includes first predetermined configuration information and second predetermined configuration information. A CP is determined based on a subcarrier spacing and a CP type of data transmission. The MTTD is determined based on the first predetermined configuration information in response to the RTD being equal to or greater than the CP, or the MTTD is determined based on the second predetermined configuration information in response to the RTD being equal to or less than the CP. A transmission operation of multiple downlink control information (M-DCI) of a multiple transmission reception point (mTRP) of the terminal is scheduled based on the MTTD. The first predetermined configuration information indicates a mapping relationship between a frequency range and the MTTD, and the second predetermined configuration information indicates a mapping relationship between a frequency range, a predetermined value, and the CP, and the predetermined value and the cyclic prefix are used to determine the corresponding MTTD. In addition, the CP type may be a first CP type or a second CP type, and for example, the first CP type may be a normal CP and the second CP type may be an extended CP.

[0072] In some embodiments, the mapping relationship between the frequency ranges and the MTTDs may be a one-to-one relationship, i.e., one frequency range may correspond to one MTTD. Thus, a terminal and / or a network device may determine a frequency range to be used, and then determine the MTTD corresponding to the frequency range to be used based on the mapping relationship, and schedule transmission of multi-downlink control information M-DCI of a multi-transmission reception point mTRP of the terminal. Alternatively, the mapping relationship between the frequency ranges and the MTTDs may be a one-to-many relationship, i.e., one frequency range may correspond to at least two MTTDs. Thus, a terminal and / or a network device may determine a frequency range to be used, and then determine at least two MTTDs corresponding to the frequency range to be used based on the mapping relationship, and then determine one MTTD from the at least two MTTDs, and schedule transmission of multi-downlink control information M-DCI of a multi-transmission reception point mTRP of the terminal. Alternatively, the mapping relationship between the frequency ranges and the MTTD may be a many-to-one relationship, i.e., multiple frequency ranges may correspond to one MTTD, and in this way, the terminal and / or network device can schedule the transmission of multi-downlink control information M-DCI of the multi-transmission reception point mTRP of the terminal based on the MTTD, regardless of which frequency range is used.

[0073] In one embodiment, the MTTD supported by the terminal is determined based on terminal capability information, where the terminal capability information indicates the MTTD, and a transmission operation of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal is scheduled based on the MTTD.

[0074] In one embodiment, the method includes receiving terminal capability information transmitted from the terminal, determining the MTTD supported by the terminal based on the terminal capability information, where the terminal capability information indicates the MTTD, and scheduling transmission operations of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal based on the MTTD.

[0075] In addition, the terminal capability information may be intended to indicate capabilities related to realizing the transmission of multi-downlink control information M-DCI of a multi-transmission receiving point mTRP supported by the terminal in a scenario where the transmission of multi-downlink control information M-DCI of a multi-transmission receiving point mTRP of the terminal is scheduled, for example, the maximum transmission link time difference between different TRPs that the terminal can support.

[0076] In one embodiment, the method includes receiving terminal capability information transmitted from the terminal, where the MTTD is determined based on an operating frequency range or the MTTD is determined based on a current operating frequency band, determining the MTTD supported by the terminal based on the terminal capability information, where the terminal capability information indicates the MTTD, and scheduling a transmission operation of multiple downlink control information (M-DCI) of a multiple transmission reception point (mTRP) of the terminal based on the MTTD.

[0077] In one embodiment, in response to configuring predetermined configuration information and receiving the terminal capability information, the MTTD supported by the terminal is determined based on the terminal capability information, and a transmission operation of multi-downlink control information (M-DCI) of a multi-transmission reception point (mTRP) of the terminal is scheduled based on the MTTD.

[0078] In an embodiment of the present disclosure, a maximum transmission time difference (MTTD) supported by a terminal is determined, and a transmission operation of multi-downlink control information (M-DCI) of a multi-transmission receiving point (mTRP) of the terminal is scheduled based on the MTTD. Here, whether to schedule transmission of multi-downlink control information (M-DCI) of a multi-transmission receiving point (mTRP) of the terminal can be determined based on the maximum transmission time difference (MTTD) supported by the terminal.
