Compared with the traditional 4-step random access process, the 2-step random access process can reduce the delay and time of uplink data transmission. Signaling overhead. As shown in Figure 1, the 2-step random access process includes step S1, the terminal device sends MsgA, that is, the terminal device selects (physical random access channel, PRACH) resources and physical uplink shared channel (physical uplink shared channel, PUSCH) resource units. And send random access preamble (preamble) on PRACH resource and use PUSCH resource unit to send uplink data. S2. The network device sends a random access response to the terminal device, such as a message B (messageB, MsgB), where contention resolution information may be included in the MsgB.

在2步随机接入过程中，preamble与上行数据在同一消息(msgA)中发送，由于PRACH时频资源和PUSCH资源单元的时频位置不同，网络设备接收到一个preamble时，无法确定与该preamble在同一消息中发送的上行数据所使用的PUSCH资源单元，即无法确定与该preamble关联的PUSCH资源单元，导致无法正确接收上行数据。In the 2-step random access process, the preamble and the uplink data are sent in the same message (msgA).

The start position, the other is to configure the relative position relative to the PRACH time-frequency resource, that is, configure the start position of the PUSCH time-frequency resource by configuring the time domain offset from the PRACH time-frequency resource. When PUSCH resources are represented by PUSCH transmission opportunities, the PUSCH time-domain resource configuration can be described by some resource configurations related to PUSCH transmission opportunities.

That is, in each 10ms, the preamble set associated with the RO on time slot 2, time slot 5 and time slot 8 is associated with the PUSCH resource unit on time slot 6 and time slot 1.

在一些实施例中，第一时间段的长度可以根据PRACH时频资源配置、PUSCH资源单元配置以及预定义的规则确定的。示例性的，预定义的规则可以是设置第一时间段包括M个PRACH传输机会，且该M个PRACH传输机会都能在第一时间段内关联到位于自身时域资源之后的PUSCH资源单元。M为大于等于1的整数。In some embodiments, the length of the first time period may be determined according to PRACH time-frequency resource configuration, PUSCH resource unit configuration, and predefined rules. Exemplarily, the predefined rule may be to set the first time period to include M PRACH transmission opportunities, and the M PRACH transmission opportunities can be associated with the PUSCH resource unit located behind the own time domain resource within the first time period. M is an integer greater than or equal to 1.

如图7所示，示出了多个连续的时间段，例如时间段0和时间段1，第一时间段可以是其中的一个。预定义的规则可以是设置第一时间段包括3个PRACH传输机会，且该3个PRACH传输机会都能在第一时间段内关联到位于自身时域资源之后的PUSCH资源单元。当第一PRACH时频资源为时隙2上的RO时，时间段0为第一时间段，第一时间段包括3个RO，且该3个RO都能在第一时间段内关联到位于自身时域资源之后的PUSCH资源单元。即时隙2、时隙5和时隙8上的RO所关联的preamble集合关联到时隙3、时隙6和时隙9上的PUSCH资源单元集合。As shown in FIG. 7, multiple consecutive time periods are shown, such as time period 0 and time period 1, and the first time period may be one of them. The predefined rule may be to set the first time period to include 3 PRACH transmission opportunities, and the 3 PRACH transmission opportunities can all be associated with the PUSCH resource unit located behind the own time domain resource within the first time period. When the first PRACH time-frequency resource is the RO on time slot 2, the time period 0 is the first time period, and the first time period includes 3 ROs, and the 3 ROs can be associated with the RO in the first time period. PUSCH resource unit after its own time domain resources. That is, the preamble set associated with the RO on time slot 2, time slot 5, and time slot 8 is associated with the PUSCH resource unit set on time slot 3, time slot 6 and time slot 9.

此外，如果一些PRACH时频资源或PUSCH资源单元跨多个时间段，则这些PRACH时频资源或PUSCH资源单元属于其起始位置所在的时间段，或者其结束位置所在的时间段，或者这些PRACH时频资源或PUSCH资源单元不属于任何时间段，即这些PRACH时频资源或PUSCH资源单元不参与msgA映射。In addition, if some PRACH time-frequency resources or PUSCH resource units span multiple time periods, these PRACH time-frequency resources or PUSCH resource units belong to the time period where their start position is located, or the time period where their end position is located, or these PRACH Time-frequency resources or PUSCH resource units do not belong to any time period, that is, these PRACH time-frequency resources or PUSCH resource units do not participate in msgA mapping.

举例来说，如图9所示，时隙6和时隙7上的RO跨2个时间段，即同时处于时间段0和时间段1内，该RO可以属于其起始位置所在的时间段，即时间段0，此时，时间段0内，时隙2和时隙3上的RO所关联的preamble集合以及时隙6和时隙7上的RO所关联的preamble集合都与时隙6上的PUSCH资源单元集合进行映射。或者，时隙6和时隙7上的RO所关联的preamble集合可以属于其结束位置所在的时间段，即时间段1，此时，时间段1内，时隙6和7上的RO所关联的preamble集合与时隙1上的PUSCH资源单元集合映射。或者，时隙6和7上的RO不属于任何时间段，此时，时间段1内，时隙1上的PUSCH资源单元集合不与任何时隙上的RO所关联的preamble集合进行映射，即时隙1上的PUSCH资源单元集合不用于MsgA传输。For example, as shown in Fig. 9, the RO on time slot 6 and time slot 7 spans two time periods, that is, both in time period 0 and time period 1, the RO can belong to the time period where its starting position is located , That is, time period 0. At this time, in time period 0, the preamble set associated with RO on time slot 2 and time slot 3, and the preamble set associated with RO on time slot 6 and time slot 7 are all the same as time slot 6. Mapping on the PUSCH resource unit set. Or, the preamble set associated with ROs on time slots 6 and 7 may belong to the time period where the end position is located, that is, time period 1. At this time, in time period 1, the ROs on time slots 6 and 7 are associated The set of preambles is mapped to the set of PUSCH resource units on slot 1. Or, the ROs on time slots 6 and 7 do not belong to any time period. At this time, in time period 1, the PUSCH resource unit set on time slot 1 is not mapped to the preamble set associated with the RO on any time slot. The PUSCH resource unit set on slot 1 is not used for MsgA transmission.

此外，如果PUSCH传输机会存在重复传输，则在第一时间段内，preamble集合仅关联到某个特定的PUSCH传输机会上的PUSCH资源单元集合。该特定的PUSCH传输机会可以是重复传输的PUSCH传输机会中的首个PUSCH传输机会，也可以是网络设备配置的第M个PUSCH传输机会，M为大于等于1的整数。In addition, if there is repeated transmission at the PUSCH transmission opportunity, in the first time period, the preamble set is only associated with the PUSCH resource unit set on a certain PUSCH transmission opportunity. The specific PUSCH transmission opportunity may be the first PUSCH transmission opportunity among the repeated PUSCH transmission opportunities, or may be the M th PUSCH transmission opportunity configured by the network device, and M is an integer greater than or equal to 1.

举例来说，如图7所示，在时间段0内，若时隙6和时隙9上的PO是时隙3上的PO的重传，则时隙2、时隙5和时隙8上的RO所关联的preamble集合可以仅与特定的PO上的PUSCH资源单元集合关联。特定的PO可以是时隙3上的PO。即在时间段0内，时隙2、时隙5和时隙8上的RO所关联的preamble集合可以仅与时隙3上的PO上的PUSCH资源单元集合关联。For example, as shown in Figure 7, in time period 0, if the PO on time slot 6 and time slot 9 is a retransmission of the PO on time slot 3, then time slot 2, time slot 5 and time slot 8 The preamble set associated with the RO above may only be associated with the PUSCH resource unit set on the specific PO. The specific PO may be the PO on time slot 3. That is, in the time period 0, the preamble set associated with the RO on the time slot 2, the time slot 5 and the time slot 8 may only be associated with the PUSCH resource unit set on the PO on the time slot 3.

如果PRACH时频资源存在重复传输，则在第一时间段内，重复传输的PRACH时频资源中的某个特定PRACH时频资源上的preamble集合关联第一时间段内的PUSCH资源单元集合。该特定的PRACH时频资源上可以是重复传输的PRACH时频资源中的首个PRACH时频资源，也可以是网络设备配置的第M个PRACH时频资源。If there is repeated transmission of the PRACH time-frequency resource, in the first time period, the preamble set on a specific PRACH time-frequency resource in the repeatedly transmitted PRACH time-frequency resource is associated with the PUSCH resource unit set in the first time period. The specific PRACH time-frequency resource may be the first PRACH time-frequency resource among the repeatedly transmitted PRACH time-frequency resources, or it may be the Mth PRACH time-frequency resource configured by the network device.

举例来说，如图7所示，若时隙5和时隙8上的RO是时隙2上的RO的重传，则在时间段0内，时隙3、时隙6和时隙9上的PUSCH资源单元集合仅与特定的RO所关联的preamble集合关联。特定的RO可以是时隙2上的RO。即在时间段0内，时隙3、时隙6和时隙9上的PUSCH资源单元集合仅与时隙2上的RO所关联的preamble集合关联。For example, as shown in Figure 7, if the ROs on time slot 5 and 8 are retransmissions of RO on time slot 2, then in time period 0, time slot 3, time slot 6 and time slot 9 The above PUSCH resource unit set is only associated with the preamble set associated with a specific RO. The specific RO may be the RO on time slot 2. That is, in time period 0, the PUSCH resource unit sets on time slot 3, time slot 6 and time slot 9 are only associated with the preamble set associated with the RO on time slot 2.

可选的，在第一时间段内，PRACH时频资源仅映射到位于自身时域资源之后的PUSCH资源单元，或者，preamble仅映射到位于其关联的PRACH时频资源的时域资源之后的PUSCH资源单元。Optionally, in the first time period, the PRACH time-frequency resource is only mapped to the PUSCH resource unit located after its own time-domain resource, or the preamble is only mapped to the PUSCH located after the time-domain resource of its associated PRACH time-frequency resource Resource unit.

可选的，在第一时间段内，如果存在一些PUSCH资源单元没有映射到PRACH时频资源或者preamble，则这些PUSCH资源单元不用于msgA传输。Optionally, in the first time period, if there are some PUSCH resource units that are not mapped to PRACH time-frequency resources or preambles, these PUSCH resource units are not used for msgA transmission.

可选的，在第一时间段内，如果存在一些PRACH时频资源或者preamble没有映射到PUSCH资源单元，则这些PRACH时频资源或者preamble不用于msgA传输。Optionally, in the first time period, if there are some PRACH time-frequency resources or preambles are not mapped to PUSCH resource units, these PRACH time-frequency resources or preambles are not used for msgA transmission.

可选的，在第一时间段内，如果存在一些PRACH时频资源，在这些PRACH时频资源的时域资源之后没有PUSCH资源单元，则这些PRACH时频资源不用于msgA传输，或者，这些PRACH时频资源用于四步随机接入传输，或者，这些PRACH时频资源可用于该PRACH时频资源之前某个特定的可用于msgA传输的PRACH时频资源的重复传输。Optionally, in the first time period, if there are some PRACH time-frequency resources and there is no PUSCH resource unit after the time-domain resources of these PRACH time-frequency resources, these PRACH time-frequency resources are not used for msgA transmission, or these PRACH time-frequency resources The time-frequency resources are used for four-step random access transmission, or these PRACH time-frequency resources can be used for repeated transmission of a specific PRACH time-frequency resource that can be used for msgA transmission before the PRACH time-frequency resource.

可选的，在第一时间段内，如果存在一些PUSCH资源单元，在这些PUSCH资源单元的时域资源之前没有PRACH时频资源，则这些PUSCH资源单元不用于msgA传输，或者，这些PUSCH资源单元可用于该PUSCH资源单元之前某个可用于msgA传输的PUSCH资源单元的重复传输。Optionally, in the first time period, if there are some PUSCH resource units, and there are no PRACH time-frequency resources before the time domain resources of these PUSCH resource units, these PUSCH resource units are not used for msgA transmission, or these PUSCH resource units It can be used for repeated transmission of a PUSCH resource unit that can be used for msgA transmission before the PUSCH resource unit.

举例来说，如图10所示，PRACH时域资源配置周期的起始位置为10ms无线帧的时隙0，周期的长度为10ms，即一个无线帧。在每个10ms无线帧内的时隙2上配置有一个RO。PUSCH时域资源配置周期为独立配置，起始位置为10ms无线帧的时隙0和时隙5，周期的长度为5ms，在每个10ms无线帧内的时隙1和时隙6上各配置有两个PO。For example, as shown in FIG. 10, the starting position of the PRACH time domain resource configuration period is time slot 0 of a 10ms radio frame, and the length of the period is 10ms, that is, one radio frame. An RO is configured on time slot 2 in each 10ms radio frame. The PUSCH time domain resource configuration cycle is an independent configuration. The starting position is time slot 0 and time slot 5 of a 10ms radio frame, and the length of the cycle is 5ms. Each configuration is configured on time slot 1 and time slot 6 in each 10ms radio frame. There are two POs.

假设第一时间段的长度等于PUSCH时域资源配置周期的长度，即第一时间段的长度为5ms，第一时间段的起始位置为一个PUSCH时域资源配置周期内最后一个PUSCH传输机会所在时隙的下一个时隙的起始位置，即第一时间段的起始位置可以为时隙2和时隙7的起始位置。图10中示出了多个连续的时间段，例如时间段0、时间段1和时间段2，第一时间段可以是其中的任一个时间段。在时间段0内，时隙2上的RO所关联的preamble集合关联到时隙6上的PUSCH资源单元集合。在时间段1内，由于时隙1上的PUSCH资源单元集合的时域资源之前没有PRACH时频资源，也就没有preamble可以与时隙1上的PUSCH资源单元集合关联，因此时隙1上的PUSCH资源单元集合不用于msgA传输，或者时隙1上的PUSCH资源单元集合可用于时隙6上的PUSCH资源单元集合的重复传输。在时间段2内，时隙2上的RO所关联的preamble集合关联到时隙6上的PUSCH资源单元集合。Assuming that the length of the first time period is equal to the length of the PUSCH time domain resource configuration period, that is, the length of the first time period is 5ms, and the starting position of the first time period is the last PUSCH transmission opportunity in a PUSCH time domain resource configuration period The starting position of the next time slot of the time slot, that is, the starting position of the first time period may be the starting position of time slot 2 and time slot 7. FIG. 10 shows multiple consecutive time periods, such as time period 0, time period 1, and time period 2, and the first time period may be any one of them. In time period 0, the preamble set associated with the RO on time slot 2 is associated with the PUSCH resource unit set on time slot 6. In time period 1, since there is no PRACH time-frequency resource before the time domain resources of the PUSCH resource unit set on time slot 1, there is no preamble that can be associated with the PUSCH resource unit set on time slot 1. The PUSCH resource unit set is not used for msgA transmission, or the PUSCH resource unit set on time slot 1 can be used for repeated transmission of the PUSCH resource unit set on time slot 6. In time period 2, the preamble set associated with the RO on time slot 2 is associated with the PUSCH resource unit set on time slot 6.

在一些实施例中，第一时间段的长度是根据SSB与PRACH时频资源之间的关联周期/映射周期的长度确定的。SSB与PRACH时频资源的关联周期的长度可以是PRACH时域资源配置周期的长度的整数倍，在SSB与PRACH时频资源的关联周期内，所有实际发送的SSB都至少映射到PRACH时频资源一遍。多个SSB与PRACH时频资源的关联周期可以组成一个SSB与PRACH时频资源的关联周期图样，该关联周期图样至多每160ms重复一次。In some embodiments, the length of the first time period is determined according to the length of the association period/mapping period between the SSB and the PRACH time-frequency resource. The length of the association period between SSB and PRACH time-frequency resources can be an integer multiple of the length of the PRACH time-domain resource configuration period. In the association period between SSB and PRACH time-frequency resources, all actually sent SSBs are mapped to at least PRACH time-frequency resources Again. The association period between multiple SSBs and PRACH time-frequency resources may form an association period pattern between SSB and PRACH time-frequency resources, and the association period pattern repeats at most every 160 ms.

举例来说，如图11所示，假设一个SSB与PRACH时频资源的关联周期图样的长度为160ms，该160ms内，SSB与PRACH时频资源的关联周期图样可以包括6个SSB与PRACH时频资源的关联周期，分别可以为关联周期0、关联周期1、关联周期2、关联周期3、关联周期4、关联周期5，剩余的10ms内SSB与PRACH时频资源不进行映射。SSB与PRACH时频资源的关联周期的长度可以有多种取值。例如，关联周期0、关联周期1、关联周期2、关联周期3、关联周期4和关联周期5的长度分别可以为40ms，10ms，20ms，40ms，20ms和20ms。可以根据SSB与PRACH时频资源的关联周期图样确定一个时间段图样，该时间段图样的周期可以为160ms。每个时间段图样内可以包括6个时间段，长度分别为40ms，10ms，20ms，40ms，20ms和20ms，第一时间段可以是其中的一个。第一时间段内，配置有RO的时隙上的preamble集合关联到配置有PO的时隙上的PUSCH资源单元集合。For example, as shown in FIG. 11, assuming that the length of an association period pattern between SSB and PRACH time-frequency resources is 160 ms, within this 160 ms, the association period pattern between SSB and PRACH time-frequency resources may include 6 SSB and PRACH time-frequency resources. The association period of the resources may be association period 0, association period 1, association period 2, association period 3, association period 4, association period 5, and SSB and PRACH time-frequency resources are not mapped in the remaining 10 ms. The length of the association period between the SSB and the PRACH time-frequency resource can have various values. For example, the length of association period 0, association period 1, association period 2, association period 3, association period 4, and association period 5 may be 40 ms, 10 ms, 20 ms, 40 ms, 20 ms, and 20 ms, respectively. A time period pattern may be determined according to the associated period pattern of the SSB and the PRACH time-frequency resource, and the period of the time period pattern may be 160 ms. Each time period pattern can include 6 time periods, with lengths of 40ms, 10ms, 20ms, 40ms, 20ms, and 20ms respectively, and the first time period can be one of them. In the first time period, the preamble set on the time slot configured with RO is associated with the PUSCH resource unit set on the time slot configured with PO.

在一些实施例中，第一时间段是第一PRACH时频资源关联的时间段，第一时间段的起始位置与第一PRACH时频资源的时域起始位置相同，或者，第一时间段是第一PRACH时频资源所在时隙关联的时间段，第一时间段的起始位置与第一PRACH时频资源所在时隙的起始位置相同。第一PRACH时频资源所在时隙可以是指普通时隙或PRACH时隙，普通时隙是指以PUSCH子载波间隔为基准，或者以上行带宽部分(bandwidth part，BWP)子载波间隔为基准的时隙，PRACH时隙即与PRACH子载波间隔相关的时隙。或者，第一时间段的起始位置与第一PRACH时频资源所在的子帧的起始位置相同。In some embodiments, the first time period is a time period associated with the first PRACH time-frequency resource, and the start position of the first time period is the same as the time domain start position of the first PRACH time-frequency resource, or the first time The segment is the time period associated with the time slot where the first PRACH time-frequency resource is located, and the start position of the first time period is the same as the start position of the time slot where the first PRACH time-frequency resource is located. The time slot where the first PRACH time-frequency resource is located can refer to a normal time slot or a PRACH time slot. The normal time slot refers to the PUSCH subcarrier interval as a reference, or the upstream bandwidth part (BWP) subcarrier interval as a reference Time slot, PRACH time slot is the time slot related to PRACH sub-carrier spacing. Or, the start position of the first time period is the same as the start position of the subframe where the first PRACH time-frequency resource is located.

举例来说，如图12所示，假设每个10ms无线帧内，时隙0、时隙4和时隙8上各配置有一个RO，时隙1、时隙5和时隙9上各配置有两个PO。若第一PRACH时频资源所在的时隙为时隙0，第一时间段(例如，时间段0)的起始位置可以为时隙0的起始位置，第一时间段的长度可以是基站配置的，例如为3ms。时间段0内，时隙0上的RO所关联的preamble集合可以关联到时隙1上的PUSCH资源单元集合。若第一PRACH时频资源所在的时隙为时隙4，第一时间段(例如，时间段1)的起始位置可以为时隙4的起始位置，第一时间段的长度可以是基站配置的，例如为3ms。时间段1内，时隙4上的RO所关联的preamble集合可以关联到时隙5上的PUSCH资源单元集合。若第一PRACH时频资源所在的时隙为时隙8，第一时间段(例如，时间段2)的起始位置可以为时隙8的起始位置，第一时间段的长度可以是基站配置的，例如为3ms。时间段2内，时隙8上的RO所关联的preamble集合可以关联到时隙9上的PUSCH资源单元集合。For example, as shown in Figure 12, assume that in each 10ms radio frame, one RO is configured on time slot 0, time slot 4 and time slot 8, and time slot 1, time slot 5 and time slot 9 are configured respectively There are two POs. If the time slot where the first PRACH time-frequency resource is located is time slot 0, the start position of the first time period (for example, time period 0) may be the start position of time slot 0, and the length of the first time period may be the base station Configured, for example, 3ms. In time period 0, the preamble set associated with the RO on time slot 0 can be associated with the PUSCH resource unit set on time slot 1. If the time slot where the first PRACH time-frequency resource is located is time slot 4, the start position of the first time period (for example, time period 1) may be the start position of time slot 4, and the length of the first time period may be the base station Configured, for example, 3ms. In time period 1, the preamble set associated with the RO on time slot 4 can be associated with the PUSCH resource unit set on time slot 5. If the time slot where the first PRACH time-frequency resource is located is time slot 8, the start position of the first time period (for example, time period 2) may be the start position of time slot 8, and the length of the first time period may be the base station Configured, for example, 3ms. In time period 2, the preamble set associated with the RO on time slot 8 can be associated with the PUSCH resource unit set on time slot 9.

在一些实施例中，若第一PRACH时频资源所在的时隙位于N个连续的时隙中，其中，N个连续的时隙中的每个时隙均配置有PRACH时频资源，则第一时间段的起始位置与N个连续的时隙中最早的时隙的起始位置相同，N为大于或者等于2的整数。若第一PRACH时频资源所在时隙的前一个时隙未配置有PRACH时频资源，则第一时间段的起始位置与第一PRACH时频资源所在时隙的起始位置相同。In some embodiments, if the time slot in which the first PRACH time-frequency resource is located is in N consecutive time slots, where each of the N consecutive time slots is configured with a PRACH time-frequency resource, then The starting position of a period of time is the same as the starting position of the earliest time slot among N consecutive time slots, and N is an integer greater than or equal to 2. If the previous time slot of the time slot where the first PRACH time-frequency resource is located is not configured with the PRACH time-frequency resource, the starting position of the first time period is the same as the starting position of the time slot where the first PRACH time-frequency resource is located.

举例来说，如图13A所示，假设每个10ms无线帧内，时隙3、时隙4和时隙9上各配置有一个RO，时隙5、时隙6和时隙1上各配置有两个PO。若第一PRACH时频资源所在的时隙为时隙4，由于时隙4与配置有RO的时隙3连续，第一时间段(例如，时间段0)的起始位置与连续的时隙中最早的时隙的起始位置相同，即第一时间段的起始位置为时隙3的起始位置，第一时间段的长度可以是基站配置的，例如为4ms。时隙3和时隙4上的RO所关联的preamble集合关联到时隙5和时隙6上的PUSCH资源单元集合。若第一PRACH时频资源所在的时隙为时隙9，由于时隙9的前一个时隙(即时隙8)未配置有PRACH时频资源，第一时间段(例如，时间段1)的起始位置与第一PRACH时频资源所在时隙的起始位置相同，即第一时间段的起始位置为时隙9的起始位置，第一时间段的长度可以是基站配置的，例如为4ms。时间段1内，时隙9上的RO所关联的preamble集合关联到时隙1上的PUSCH资源单元集合。For example, as shown in Figure 13A, assume that in each 10ms wireless frame, one RO is configured on time slot 3, time slot 4, and time slot 9, and time slot 5, time slot 6 and time slot 1 are configured on each There are two POs. If the time slot where the first PRACH time-frequency resource is located is time slot 4, since time slot 4 is continuous with time slot 3 configured with RO, the starting position of the first time period (for example, time period 0) is the same as the continuous time slot The start position of the earliest time slot in the same, that is, the start position of the first time period is the start position of time slot 3, and the length of the first time period may be configured by the base station, for example, 4 ms. The preamble set associated with the RO on time slot 3 and time slot 4 is associated with the PUSCH resource unit set on time slot 5 and time slot 6. If the time slot where the first PRACH time-frequency resource is located is time slot 9, since the previous time slot of time slot 9 (that is, time slot 8) is not configured with PRACH time-frequency resources, the first time period (for example, time period 1) The starting position is the same as the starting position of the time slot where the first PRACH time-frequency resource is located, that is, the starting position of the first time period is the starting position of time slot 9, and the length of the first time period can be configured by the base station, for example Is 4ms. In time period 1, the preamble set associated with the RO on time slot 9 is associated with the PUSCH resource unit set on time slot 1.

在一些实施例中，N个连续的配置有PRACH时频资源的时隙中的每个时隙均可以关联一个时间段，每个时隙对应的时间段的起始位置为该时隙的起始位置，每个时隙对应的时间段的长度可以相同。连续的两个配置有PRACH时频资源的时隙所对应的时间段可能会重叠，在这种情况下，第一时间段内的PUSCH资源单元集合不包含已与第二时间段中的PRACH时频资源关联的PUSCH资源单元，或者，第一时间段内的PUSCH资源单元集合不包含已与第二时间段中的PRACH时频资源所关联的preamble关联的PUSCH资源单元，第二时间段位于第一时间段之前，或者说，第二时间段的起始位置早于第一时间段。In some embodiments, each of the N consecutive time slots configured with PRACH time-frequency resources can be associated with a time period, and the start position of the time period corresponding to each time slot is the beginning of the time slot. Starting position, the length of the time period corresponding to each time slot can be the same. The time periods corresponding to two consecutive time slots configured with PRACH time-frequency resources may overlap. In this case, the PUSCH resource unit set in the first time period does not include the PRACH time period in the second time period. The PUSCH resource unit associated with the frequency resource, or the PUSCH resource unit set in the first time period does not include the PUSCH resource unit associated with the preamble associated with the PRACH time-frequency resource in the second time period, and the second time period is located in the first time period. A time period before, or in other words, the starting position of the second time period is earlier than the first time period.

举例来说，如图13B所示，假设每个10ms无线帧内，时隙3、时隙4和时隙9上各配置有一个RO，时隙5、时隙6和时隙1上各配置有两个PO。若每个包含PRACH时频资源的时隙对应一个时间段，每个时间段的长度可以为3ms。时隙3、时隙4和时隙9可以各关联一个时域长度为3ms的时间段，分别可以为时间段0、时间段1和时间段2。由于时间段0是时隙3所关联的时间段，因此时隙3上的RO所关联的preamble集合关联到位于时间段0内的PUSCH资源单元集合，即时隙5上的PUSCH资源单元集合。由于时间段1是时隙4所关联的时间段，时隙4上的RO所关联的preamble集合本可以关联到位于时间段1内的PUSCH资源单元集合，即时隙5和时隙6上的PUSCH资源单元集合，但是由于时隙5上的PUSCH资源单元集合已与时间段0(即第二时间段)中的PRACH时频资源(即时隙3上的PRACH时频资源)关联，因此时隙4上的RO所关联的preamble集合仅关联到位于时隙6上的PUSCH资源单元集合。若第一PRACH时频资源所在的时隙为时隙9，时隙9上的RO所关联的preamble集合可以关联位于时间段2内的PUSCH资源单元集合，即时隙1上的PUSCH资源单元集合。For example, as shown in Figure 13B, assume that in each 10ms radio frame, one RO is configured on time slot 3, time slot 4, and time slot 9, and time slot 5, time slot 6 and time slot 1 are each configured There are two POs. If each time slot containing the PRACH time-frequency resource corresponds to a time period, the length of each time period can be 3 ms. Time slot 3, time slot 4, and time slot 9 may each be associated with a time period with a time domain length of 3 ms, which may be time period 0, time period 1, and time period 2, respectively. Since time slot 0 is the time slot associated with slot 3, the preamble set associated with the RO on slot 3 is associated with the PUSCH resource unit set located in time slot 0, that is, the PUSCH resource unit set on slot 5. Since time slot 1 is the time slot associated with slot 4, the preamble set associated with RO on slot 4 could be associated with the PUSCH resource unit set located in time slot 1, namely PUSCH on slot 5 and slot 6. Resource unit set, but because the PUSCH resource unit set on time slot 5 has been associated with the PRACH time-frequency resource (that is, the PRACH time-frequency resource on time slot 3) in time period 0 (that is, the second time period), time slot 4 The preamble set associated with the RO above is only associated with the PUSCH resource unit set located on slot 6. If the time slot where the first PRACH time-frequency resource is located is time slot 9, the preamble set associated with the RO on time slot 9 may be associated with the PUSCH resource unit set located in time period 2, that is, the PUSCH resource unit set on time slot 1.

在一些实施例中，第一时间段是目标PUSCH资源单元关联的时间段，第一时间段的结束位置与目标PUSCH资源单元的时域结束位置相同，目标PUSCH资源单元的时域位置晚于第一PRACH时频资源的时域位置，终端设备可以根据第一时间段的长度确定第一PRACH时频资源的时域位置确定目标PUSCH资源单元的时域位置。或者，第一时间段是目标时隙关联的时间段，第一时间段的结束位置与配置了PUSCH资源单元的目标时隙的结束位置相同。目标时隙为配置了PUSCH资源单元的时隙，目标时隙的时域位置晚于第一PRACH时频资源的时域位置，终端设备可以根据第一时间段的长度确定第一PRACH时频资源的时域位置确定目标时隙的时域位置。或者，第一时间段是目标子帧关联的时间段，第一时间段的结束位置与配置了PUSCH资源单元的目标子帧的结束位置相同。目标子帧为配置了PUSCH资源单元的子帧，目标子帧的时域位置晚于第一PRACH时频资源的时域位置，终端设备可以根据第一时间段的长度确定第一PRACH时频资源的时域位置确定目标子帧的时域位置。In some embodiments, the first time period is the time period associated with the target PUSCH resource unit, the end position of the first time period is the same as the time domain end position of the target PUSCH resource unit, and the time domain position of the target PUSCH resource unit is later than the first time period. 1. The time domain position of the PRACH time-frequency resource. The terminal device may determine the time domain position of the first PRACH time-frequency resource according to the length of the first time period to determine the time domain position of the target PUSCH resource unit. Alternatively, the first time period is a time period associated with the target time slot, and the end position of the first time period is the same as the end position of the target time slot configured with the PUSCH resource unit. The target time slot is a time slot configured with a PUSCH resource unit. The time domain position of the target time slot is later than the time domain position of the first PRACH time-frequency resource. The terminal device can determine the first PRACH time-frequency resource according to the length of the first time period The time domain position of determines the time domain position of the target time slot. Alternatively, the first time period is a time period associated with the target subframe, and the end position of the first time period is the same as the end position of the target subframe where the PUSCH resource unit is configured. The target subframe is a subframe configured with PUSCH resource units. The time domain position of the target subframe is later than the time domain position of the first PRACH time-frequency resource. The terminal device can determine the first PRACH time-frequency resource according to the length of the first time period The time domain position of determines the time domain position of the target subframe.

举例来说，如图13C所示，假设每个10ms无线帧内，时隙3和时隙7上各配置有一个RO，时隙4和时隙8上各配置有两个PO。若第一PRACH时频资源为时隙3上的RO，第一时间段的长度可以是基站配置的，例如为3ms，时隙4上的PO的时域位置晚于时隙3上的RO的时域位置，且距离时隙3的RO的时长在3ms以内，即时隙4为目标时隙或者目标PUSCH资源单元所在的时域位置(时隙)，时隙4关联的时间段(时间段0)为第一时间段，时间段0的结束位置可以为时隙4的结束位置。时间段0内，时隙3上的RO所关联的preamble集合可以关联到时隙4上的PUSCH资源单元集合。若第一PRACH时频资源为时隙7上的RO，第一时间段的长度可以是基站配置的，例如为3ms，时隙8上的PO的时域位置晚于时隙7上的RO的时域位置，且距离时隙7的RO的时长在3ms以内，即时隙8为目标时隙或者目标PUSCH资源单元所在的时域位置(时隙)，时隙8关联的时间段(时间段1)为第一时间段，时间段1的结束位置可以为时隙8的结束位置。时间段1内，时隙7上的RO所关联的preamble集合可以关联到时隙8上的PUSCH资源单元集合。For example, as shown in FIG. 13C, it is assumed that in each 10ms radio frame, one RO is configured on time slot 3 and time slot 7, and two POs are configured on time slot 4 and time slot 8. If the first PRACH time-frequency resource is the RO on time slot 3, the length of the first time period can be configured by the base station, for example, 3 ms. The time domain position of the PO on time slot 4 is later than that of RO on time slot 3. Time domain position, and the length of RO from time slot 3 is within 3ms, that is, time slot 4 is the time domain location (time slot) where the target time slot or target PUSCH resource unit is located, and the time period associated with time slot 4 (time period 0 ) Is the first time period, and the end position of time period 0 may be the end position of time slot 4. In time period 0, the preamble set associated with the RO on time slot 3 can be associated with the PUSCH resource unit set on time slot 4. If the first PRACH time-frequency resource is the RO on time slot 7, the length of the first time period can be configured by the base station, for example, 3 ms, and the time domain position of the PO on time slot 8 is later than that of the RO on time slot 7. Time domain position, and the length of RO from time slot 7 is within 3ms, that is, time slot 8 is the time domain position (time slot) where the target time slot or the target PUSCH resource unit is located, and the time period associated with time slot 8 (time period 1 ) Is the first time period, and the end position of time period 1 may be the end position of time slot 8. In time period 1, the preamble set associated with the RO on time slot 7 can be associated with the PUSCH resource unit set on time slot 8.

在一些实施例中，第一时间段的结束位置与N个连续的时隙中最晚的时隙的结束位置相同，其中，N个连续的时隙中的每个时隙均配置有PUSCH资源单元集合，N为大于或者等于2的整数。若目标PUSCH资源单元所在时隙的后一个时隙未配置有PUSCH资源单元集合，或者目标时隙的后一个时隙未配置有PUSCH资源单元集合，则第一时间段的结束位置与目标时隙的结束位置相同。In some embodiments, the end position of the first time period is the same as the end position of the latest time slot among the N consecutive time slots, wherein each of the N consecutive time slots is configured with PUSCH resources Unit set, N is an integer greater than or equal to 2. If the next time slot of the target PUSCH resource unit is not configured with a PUSCH resource unit set, or the next time slot of the target time slot is not configured with a PUSCH resource unit set, then the end position of the first time period and the target time slot The end position is the same.

举例来说，如图14所示，假设在每个10ms无线帧内，时隙3、时隙4和时隙9上各配置有一个RO，时隙5、时隙6和时隙1上各配置有两个PO。若第一PRACH时频资源为时隙3上的RO，第一时间段的长度可以是基站配置的，例如为4ms，终端设备可以确定第一PRACH时频资源位于配置了PUSCH资源单元的时隙5和时隙6关联的第一时间段内，由于时隙5和时隙6连续且均配置有PUSCH资源单元，第一时间段(例如，时间段0)的结束位置与连续的配置有PUSCH资源单元的时隙中最晚的时隙的结束位置相同，即第一时间段的结束位置为时隙6的结束位置。时间段0内，时隙3和时隙4上的RO所关联的preamble集合关联到时隙5和时隙6上的PUSCH资源单元集合。若第一PRACH时频资源为时隙9上的RO，第一时间段的长度可以是基站配置的，例如为4ms，终端设备可以确定第一PRACH时频资源在配置了PUSCH资源单元的时隙1关联的第一时间段(时间段1)内，由于时隙1的后一个时隙未配置有PUSCH资源单元，则第一时间段的结束位置与时隙1的结束位置相同。时间段1内，时隙9上的RO所关联的preamble集合关联到时隙1上的PUSCH资源单元集合。For example, as shown in Figure 14, assuming that in each 10ms radio frame, there is an RO configured on time slot 3, time slot 4, and time slot 9, and time slot 5, time slot 6 and time slot 1 are each configured. There are two POs configured. If the first PRACH time-frequency resource is the RO on time slot 3, the length of the first time period may be configured by the base station, for example, 4 ms, and the terminal device can determine that the first PRACH time-frequency resource is located in the time slot configured with the PUSCH resource unit In the first time period associated with time slot 5 and time slot 6, since time slot 5 and time slot 6 are continuous and both are configured with PUSCH resource units, the end position of the first time period (for example, time period 0) is continuously configured with PUSCH The end position of the latest time slot in the time slots of the resource unit is the same, that is, the end position of the first time period is the end position of time slot 6. In time period 0, the preamble set associated with the RO on time slot 3 and time slot 4 is associated with the PUSCH resource unit set on time slot 5 and time slot 6. If the first PRACH time-frequency resource is the RO on time slot 9, the length of the first time period can be configured by the base station, for example, 4 ms, and the terminal device can determine that the first PRACH time-frequency resource is in the time slot where the PUSCH resource unit is configured. In the first time period associated with 1 (time period 1), since the next time slot of time slot 1 is not configured with a PUSCH resource unit, the end position of the first time period is the same as the end position of time slot 1. In time period 1, the preamble set associated with the RO on time slot 9 is associated with the PUSCH resource unit set on time slot 1.

在一些实施例中，N个连续的时隙中的每个时隙均可以配置有PUSCH资源单元，每个时隙均可以对应一个时间段，每个时隙对应的时间段的结束位置为该时隙的结束位置，每个时隙对应的时间段的长度可以相同。由于连续的两个时隙对应的时间段可能会重叠，在这种情况下，第一时间段内的PRACH时频资源不包含已与第三时间段中的PUSCH资源单元集合关联的PRACH时频资源，或者，第一时间段内的PRACH时频资源关联的preamble集合不包含已与第三时间段中的PUSCH资源单元关联的preamble，第三时间段的结束位置晚于第一时间段。In some embodiments, each of the N consecutive time slots can be configured with a PUSCH resource unit, each time slot can correspond to a time period, and the end position of the time period corresponding to each time slot is this The end position of the time slot, and the length of the time period corresponding to each time slot can be the same. Since the time periods corresponding to two consecutive time slots may overlap, in this case, the PRACH time-frequency resources in the first time period do not include the PRACH time-frequency resources that have been associated with the PUSCH resource unit set in the third time period. Resource, or, the preamble set associated with the PRACH time-frequency resource in the first time period does not include the preamble that has been associated with the PUSCH resource unit in the third time period, and the end position of the third time period is later than the first time period.

举例来说，如图13B所示，假设每个10ms无线帧内，时隙3、时隙4和时隙9上各配置有一个RO，时隙5、时隙6和时隙1上各配置有两个PO。若每个包含PUSCH资源单元的时隙对应一个时间段，每个时隙对应的时间段的结束位置为该时隙的结束位置，每个时间段的长度可以相同，例如为3ms。即时隙5、时隙6和时隙1可以各关联一个时间段，分别为时间段0、时间段1和时间段2。时间段1内，时隙6上的PUSCH资源单元集合关联到时隙4上的RO所关联的preamble集合。时间0内，时隙5上的PUSCH资源单元集合本可以关联到时隙3和时隙4上的RO所关联的preamble集合。但由于时隙4上的RO所关联的preamble集合已与时间1(第三时间段)内的PUSCH资源单元集合关联过了，因此时间0内的PRACH时频资源不包含时隙4上的RO所关联的preamble集合。时间段2内，时隙9上的RO所关联的preamble集合关联到时隙1上的PUSCH资源单元集合。For example, as shown in Figure 13B, assume that in each 10ms radio frame, one RO is configured on time slot 3, time slot 4, and time slot 9, and time slot 5, time slot 6 and time slot 1 are each configured There are two POs. If each time slot containing the PUSCH resource unit corresponds to a time period, the end position of the time period corresponding to each time slot is the end position of the time slot, and the length of each time period may be the same, for example, 3 ms. That is, time slot 5, time slot 6 and time slot 1 can each be associated with a time period, which is time period 0, time period 1, and time period 2, respectively. In time period 1, the PUSCH resource unit set on time slot 6 is associated with the preamble set associated with RO on time slot 4. In time 0, the PUSCH resource unit set on time slot 5 can be associated with the preamble set associated with RO on time slot 3 and time slot 4. However, because the preamble set associated with the RO on time slot 4 has been associated with the PUSCH resource unit set in time 1 (the third time period), the PRACH time-frequency resource in time 0 does not include the RO on time slot 4 The associated preamble collection. In time period 2, the preamble set associated with the RO on time slot 9 is associated with the PUSCH resource unit set on time slot 1.

在一些实施例中，第一时间段的长度为两个配置有PRACH时频资源的时隙之间的时间长度。第一时间段的起始位置为每个配置有PRACH时频资源的时隙的起始位置。In some embodiments, the length of the first time period is the length of time between two time slots configured with PRACH time-frequency resources. The starting position of the first time period is the starting position of each time slot configured with PRACH time-frequency resources.

举例来说，如图15所示，假设在每个10ms无线帧内的时隙2、时隙5和时隙8上各配置有一个RO，时隙3、时隙6和时隙9上各配置有两个PO。第一时间段的长度等于每两个配置有RO的时隙之间的长度，第一时间段的起始位置为每个配置有RO的时隙的起始位置。图15中示出了多个连续的时间段，例如时间段0、时间段1和时间段2，第一时间段可以是其中的任一个时间段。时间段0和时间段1的长度为3ms，起始位置分别为时隙2和时隙5的起始位置，时间段2的长度为4ms，起始位置为时隙8的起始位置。时间段0内，时隙2上的RO所关联的preamble集合关联到时隙3上的PUSCH资源单元集合；时间段1内，时隙5上的RO所关联的preamble集合关联到时隙6上的PUSCH资源单元集合。时间段2内，时隙8上的RO所关联的preamble集合关联到时隙9上的PUSCH资源单元集合。For example, as shown in Figure 15, assuming that each of the time slots 2, time slots 5, and time slots 8 in each 10ms wireless frame is configured with one RO, and time slots 3, 6 and 9 are each configured. There are two POs configured. The length of the first time period is equal to the length between every two time slots configured with RO, and the start position of the first time period is the start position of each time slot configured with RO. FIG. 15 shows multiple consecutive time periods, such as time period 0, time period 1, and time period 2, and the first time period may be any one of them. The length of time period 0 and time period 1 is 3 ms, the starting positions are the starting positions of time slot 2 and time slot 5 respectively, the length of time period 2 is 4 ms, and the starting position is the starting position of time slot 8. In time period 0, the preamble set associated with RO on time slot 2 is associated with the PUSCH resource unit set on time slot 3; in time period 1, the preamble set associated with RO on time slot 5 is associated with time slot 6 A collection of PUSCH resource units. In time period 2, the preamble set associated with the RO on time slot 8 is associated with the PUSCH resource unit set on time slot 9.

在一些实施例中，第一时间段的长度为两个配置PUSCH资源单元的时隙间的时间长度，第一时间段的结束位置为每个配置有PUSCH资源单元的时隙的结束位置。In some embodiments, the length of the first time period is the length of time between two time slots configured with PUSCH resource units, and the end position of the first time period is the end position of each time slot configured with PUSCH resource units.

如图16所示，假设在每个10ms无线帧内的时隙2、时隙5和时隙8上各配置有一个RO，时隙3、时隙6和时隙9上各配置有两个PO。第一时间段的长度等于每两个配置有PO的时隙之间的长度，第一时间段的结束位置为每个配置有PO的时隙的结束位置。图16中示出了多个连续的时间段，例如时间段0、时间段1和时间段2，第一时间段可以是其中的任一个时间段。时间段0和时间段1的长度为3ms，结束位置分别为时隙6和时隙9的结束位置，根据结束位置和时长可知时间段0和时间段1的起始位置为时隙4和时隙7的起始位置；时间段2的长度为4ms，结束位置为时隙3的结束位置，根据结束位置和时长可知时间段2的起始位置为时隙0的起始位置。时间段0内，时隙5上的RO所关联的preamble集合关联到时隙6上的PUSCH资源单元集合；时间段1内，时隙8上的RO所关联的preamble集合关联到时隙9上的PUSCH资源单元集合；时间段2内，时隙2上的RO所关联的preamble集合关联到时隙3上的PUSCH资源单元集合。As shown in Figure 16, assuming that each of the time slot 2, time slot 5 and time slot 8 in each 10ms radio frame is configured with one RO, and time slot 3, time slot 6 and time slot 9 are each configured with two ROs. PO. The length of the first time period is equal to the length between every two time slots configured with PO, and the end position of the first time period is the end position of each time slot configured with PO. FIG. 16 shows multiple consecutive time periods, such as time period 0, time period 1, and time period 2, and the first time period may be any one of them. The length of time period 0 and time period 1 is 3 ms, and the end positions are the end positions of time slot 6 and time slot 9 respectively. According to the end positions and duration, the start positions of time period 0 and time period 1 are time slot 4 and time The start position of slot 7; the length of time period 2 is 4 ms, and the end position is the end position of time slot 3. According to the end position and duration, it can be known that the start position of time period 2 is the start position of time slot 0. In time period 0, the preamble set associated with RO on time slot 5 is associated with the PUSCH resource unit set on time slot 6; in time period 1, the preamble set associated with RO on time slot 8 is associated with time slot 9. The set of PUSCH resource units; in time period 2, the preamble set associated with the RO on time slot 2 is associated with the set of PUSCH resource units on time slot 3.

502、终端设备根据确定的preamble和关联规则在位于第一时间段内的PUSCH资源单元集合中确定一个PUSCH资源单元。502. The terminal device determines a PUSCH resource unit in the PUSCH resource unit set located in the first time period according to the determined preamble and association rule.

其中，关联规则用于确定preamble与PUSCH资源单元之间的关联/映射/对应关系。Among them, the association rule is used to determine the association/mapping/correspondence between the preamble and the PUSCH resource unit.

第一时间段内的preamble和PUSCH资源单元可以是一对一关联，或者多对一关联，或者一对多关联。第一时间段内的preamble和PUSCH资源单元的关联关系可以是基站配置的，也可以是预定义的，也可以是根据第一时间段内preamble的数量与PUSCH资源单元的数量计算得到的。多个时间段中不同时间段内preamble和PUSCH资源单元的关联关系可以相同，也可以不同。The preamble and PUSCH resource units in the first time period may be one-to-one association, or many-to-one association, or one-to-many association. The association relationship between the preamble and the PUSCH resource unit in the first time period may be configured by the base station, or may be predefined, or calculated based on the number of preambles and the number of PUSCH resource units in the first time period. The association relationship between the preamble and the PUSCH resource unit in different time periods in multiple time periods may be the same or different.

如图6C所示，假设每个RO上配置了16个preamble，每个PO上配置了8个资源单元，且preamble和PUSCH资源单元的关联关系是根据第一时间段内preamble的数量与PUSCH资源单元的数量计算得到的，则在时间段0内，时隙2和时隙5上的32个preamble映射到时隙6上的16个PUSCH资源单元，每

个preamble映射到一个PUSCH资源单元；在时间段1内，时隙8上的16个preamble映射到时隙1上的16个PUSCH资源单元，每

个preamble映射到一个PUSCH资源单元；在时间段2内，时隙2和时隙5上的32个preamble映射到时隙6上的16个PUSCH资源单元，每

个preamble映射到一个PUSCH资源单元。 As shown in Figure 6C, assuming that each RO is configured with 16 preambles and each PO is configured with 8 resource units, and the association between the preamble and PUSCH resource units is based on the number of preambles and PUSCH resources in the first time period The number of units is calculated, then in time slot 0, 32 preambles on time slot 2 and time slot 5 are mapped to 16 PUSCH resource units on time slot 6, each

One preamble is mapped to one PUSCH resource unit; in time period 1, the 16 preambles on time slot 8 are mapped to 16 PUSCH resource units on time slot 1, each

One preamble is mapped to one PUSCH resource unit; in time period 2, 32 preambles on time slot 2 and time slot 5 are mapped to 16 PUSCH resource units on time slot 6, each

One preamble is mapped to one PUSCH resource unit.

可选的，在第一时间段内，PRACH时频资源关联的preamble仅映射到自身时域位置之后的PUSCH资源单元。可选的，在第一时间段内，如果存在一些PRACH时频资源或者preamble没有映射到PUSCH资源单元，则这些PRACH时频资源或者preamble不用于msgA传输。Optionally, in the first time period, the preamble associated with the PRACH time-frequency resource is only mapped to the PUSCH resource unit after its own time domain position. Optionally, in the first time period, if there are some PRACH time-frequency resources or preambles are not mapped to PUSCH resource units, these PRACH time-frequency resources or preambles are not used for msgA transmission.

举例来说，如图7所示，假设每个RO上配置了12个preamble，每个PO上配置了8个资源单元。第一时间段(例如，时间段0)内preamble和PUSCH资源单元的映射关系可以是基站配置的1对1映射，或者是预定义的1对1映射。若第一时间段内，preamble仅映射到时域资源位于自己所在的PRACH传输机会之后的PUSCH传输机会上的PUSCH资源单元，则在时间段0内，时隙2上的12个preamble 1对1映射到时隙3上的前12个PUSCH资源单元，时隙5上的12个preamble 1对1映射到时隙6上的前12个PUSCH资源单元，时隙8上的12个preamble 1对1映射到时隙9上的前12个PUSCH资源单元，时隙3、时隙6、时隙9上的最后4个PUSCH资源单元没被映射，不用于msgA传输。For example, as shown in Figure 7, it is assumed that 12 preambles are configured on each RO, and 8 resource units are configured on each PO. The mapping relationship between the preamble and the PUSCH resource unit in the first time period (for example, time period 0) may be a 1-to-1 mapping configured by the base station, or a predefined 1-to-1 mapping. If in the first time period, the preamble is only mapped to the PUSCH resource unit whose time domain resource is located on the PUSCH transmission opportunity after the PRACH transmission opportunity where it is located, then in the time period 0, 12 preambles on time slot 2 1 to 1 Map to the first 12 PUSCH resource units on time slot 3, 12 preambles on time slot 5 1-to-1 mapped to the first 12 PUSCH resource units on time slot 6, and 12 preambles on time slot 8 1-to-1 The first 12 PUSCH resource units mapped to time slot 9, and the last 4 PUSCH resource units on time slot 3, time slot 6, and time slot 9 are not mapped, and are not used for msgA transmission.
