- FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:
- Step 2101 The terminal reports its OCC multiplexing capability to the network device.
- the above-mentioned OCC multiplexing capability can be used to indicate whether the terminal supports OCC multiplexing, or can be used to indicate whether the terminal supports OCC multiplexing in different services.
- the OCC multiplexing can refer to the OCC multiplexing of NPRACH by the terminal.
- the "OCC multiplexing of NPRACH" can be understood as: when different terminals send NPRACH, the NPRACH of the terminal is used to multiplex the NPRACH.
- the corresponding OCC sequence performs weighted processing on the NPRACH of the terminal, wherein the NPRACHs of different terminals correspond to different OCC sequences.
- different terminals obtain different weighted NPRACHs after weighted processing of the NPRACHs of the terminal based on the corresponding OCC sequences, and each terminal can send its own weighted NPRACH to the network device on the same time-frequency resources.
- the network device receives the weighted NPRACHs sent by each terminal on the same time-frequency resources, it can perform inverse weighted processing based on the OCC sequences corresponding to the NPRACHs of each terminal to determine the NPRACH of each terminal, thereby realizing OCC multiplexing transmission of multiple terminals on the same time-frequency resources, improving resource utilization, and realizing uplink capacity enhancement and system expansion.
- it Under the premise of limited time-frequency resources and limited terminal transmission power, it can support more terminals for uplink transmission, thereby improving uplink transmission efficiency.
- the OCC multiplexing transmission of the NPRACH may be applicable to at least one of the following situations:
- OCC multiplexing and transmission of NPRACH are performed when communicating based on different coverage enhancement levels (CE Level).
- the OCC multiplexing capability reported by the terminal may include at least one of the following:
- the terminal supports OCC multiplexing on the anchor carrier.
- the terminal may only report whether it supports OCC multiplexing. In this case, when the terminal supports OCC multiplexing, the terminal defaults to supporting OCC multiplexing in the normal random access procedure (Normal RACH procedure), and/or, the terminal defaults to supporting OCC multiplexing during EDT, and/or, the terminal defaults to supporting OCC multiplexing in all services.
- the terminal when the terminal supports OCC multiplexing, the terminal defaults to supporting OCC multiplexing in the normal random access procedure (Normal RACH procedure), and/or, the terminal defaults to supporting OCC multiplexing during EDT, and/or, the terminal defaults to supporting OCC multiplexing in all services.
- Normal RACH procedure normal random access procedure
- the terminal may report to the network device whether it supports EDT and/or whether it supports NPRACH transmission on a non-anchor carrier. At the same time, the terminal may also report to the network device whether it supports OCC multiplexing. When the terminal reports to the network device that it supports EDT and OCC multiplexing, it is considered that the terminal supports OCC multiplexing during EDT, i.e., it supports OCC multiplexing and sending of NPRACH during EDT transmission.
- the terminal when the terminal reports to the network device that it supports NPRACH transmission on a non-anchor carrier and OCC multiplexing, it is considered that the terminal supports OCC multiplexing on a non-anchor carrier, i.e., it supports OCC multiplexing and sending of NPRACH on a non-anchor carrier.
- the terminal may directly report to the network device whether the terminal supports OCC multiplexing during EDT, and/or whether the terminal supports OCC multiplexing on non-anchor carriers, and/or whether the terminal supports OCC multiplexing on anchor carriers.
- the terminal may report the OCC multiplexing capability of the terminal to the network device through a first signaling.
- the first signaling may include at least one of the following: UE assistance information (UE assistance information) signaling, UE capability (UE capability) signaling, and radio resource control (Ratio Resource Control, RRC) signaling.
- UE assistance information UE assistance information
- UE capability UE capability
- RRC Radio Resource Control
- the terminal reports its OCC multiplexing capability to the network device so that the network device can schedule appropriate resources for the terminal based on the OCC multiplexing capability of the terminal. For example, when the terminal supports OCC multiplexing, the network device can schedule resources for OCC multiplexing to the terminal; when the terminal does not support OCC multiplexing, the network device can schedule resources for non-OCC multiplexing to the terminal. Alternatively, when the terminal supports OCC multiplexing for a certain service, the network device can schedule resources for OCC multiplexing when scheduling resources for the service; when the terminal does not support OCC multiplexing for a certain service, the network device can schedule resources for non-OCC multiplexing when scheduling resources for the service. This achieves accurate and effective management of the terminal and ensures reasonable management and scheduling of terminal resources.
- Step 2102 The network device sends configuration information to the terminal.
- the configuration information may be used to configure at least one first resource set and/or at least one second resource set; wherein the first resource set may include one or more resources, and the one or more resources in the first resource set may be used for OCC multiplexing transmission of NPRACH,
- the second resource set may include one or more resources, and the one or more resources in the second resource set may be used for non-OCC multiplexing transmission of NPRACH.
- the "resources used for OCC multiplexing (i.e., the first resource set)" and the “resources used for non-OCC multiplexing (i.e., the second resource set)" will be separated from each other, thereby avoiding mutual interference between OCC multiplexing transmission and non-OCC multiplexing transmission, and ensuring the communication efficiency and communication stability of both OCC multiplexing transmission and non-OCC multiplexing transmission.
- the network device when it sends configuration information to the terminal, it may send the configuration information to the terminal based on the OCC multiplexing capability of the terminal.
- the network device sends configuration information to the terminal based on the OCC multiplexing capability of the terminal.
- the network device may send configuration information corresponding to at least one carrier to the terminal, where different carriers use the same configuration information, i.e., only one configuration information is configured for different carriers, and different carriers share the same configuration information; or, different carriers use independent configuration information, i.e., the configuration information is independently configured for different carriers, and the independent configuration information corresponding to different carriers may be the same or different.
- the different carriers here may refer to different types of carriers, and the different types of carriers may include anchor carriers and non-anchor carriers; or, the different carriers may refer to different non-anchor carriers.
- the network device may send configuration information corresponding to at least one CE Level to the terminal, wherein different CE Levels use the same configuration information, that is, only one configuration information is configured for different CE Levels, and different CE Levels share the same configuration information; or, different CE Levels use independent configuration information; that is, the configuration information is independently configured for different CE Levels, and the independent configuration information corresponding to different CE Levels may be the same or different.
- the network device may send NPRACH configuration information corresponding to the EDT service to the terminal; and send NPRACH configuration information corresponding to the non-data early transmission Non-EDT service; wherein the EDT service and the Non-EDT service use the same configuration information; that is: only one configuration information is configured for the EDT service and the Non-EDT service, and the EDT service and the Non-EDT service share the same configuration information; or, the EDT service and the Non-EDT service use independent configuration information; that is: the configuration information is independently configured for the EDT service and the Non-EDT service, and the independent configuration information corresponding to the EDT service and the Non-EDT service may be the same or different.

- the OCC sequence length may be used to determine an OCC sequence, which may be used to implement OCC multiplexing transmission of the NPRACH of the terminal.
- the OCC sequence length may also be referred to as, for example, "number of multiplexed users,” “number of OCC multiplexed users,” or “maximum number of OCC multiplexed users,” which is not specifically limited in the present disclosure.
- the first corresponding relationship may be a corresponding relationship between an OCC sequence length and a first resource set; wherein different OCC sequence lengths may correspond to different or the same first resource sets;
- the second corresponding relationship may be a corresponding relationship between an OCC sequence length and a second resource set; wherein different OCC sequence lengths may correspond to different or the same second resource sets.

结合第一方面的一些实施例,在一些实施例中,所述NPRACH的OCC复用发送适用以下至少之一情形:

所述不同载波包括不同的非锚点载波。
在上述实施例中,限定了网络设备具体如何发送配置信息的方法,其中,该配置信息用于配置至少一个第一资源集;该第一资源集中的一个或多个资源用于进行NPRACH的OCC复用发送。由此可知,本公开实施例提供了一种网络设备具体如何配置OCC复用资源的方法,实现了OCC复用资源的成功配置,以便终端后续可以基于所配置的OCC复用资源来进行NPRACH的OCC复用发送,实现了上行链路容量增强(uplink capacity enhancement)和系统扩容,在有限的时频资源以及终端有限发送功率的前提下能够支持更多的终端进行上行传输,提高了上行传输效率。

在上述实施例中,终端会向网络设备上报该终端的OCC复用能力,以便网络设备可以基于终端的OCC复用能力来对终端的OCC发送进行对应的管理。例如,当终端支持OCC复用时,网络设备可以向终端配置OCC复用资源;或者,当终端仅是支持在某个业务进行OCC复用时,网络设备可以仅向终端配置用于该业务的OCC复用资源,从而完善了OCC复用的相关管理制度,实现了对OCC复用的有效管理。

步骤2101、终端向网络设备上报终端的OCC复用能力。
可选地,上述的OCC复用能力例如可以是用于指示终端是否支持OCC复用,或者,可以用于指示终端在不同业务中是否支持OCC复用。可选地,该OCC复用可以是指终端对NPRACH的OCC复用,可选地,该“NPRACH的OCC复用”例如可以理解为:不同终端发送NPRACH时,利用该终端的NPRACH
对应的OCC序列对该终端的NPRACH进行加权处理,其中,不同终端的NPRACH对应不同的OCC序列,因此,不同终端基于对应的OCC序列对该终端的NPRACH进行加权处理之后所得到的加权处理之后的NPRACH是不同的,以及,每个终端可以将各自的加权处理之后的NPRACH在相同时频资源上发送至网络设备。网络设备接收到各个终端在相同时频资源上发送的加权处理之后的NPRACH时,可以基于各个终端的NPRACH分别对应的OCC序列来进行逆加权处理以确定出各个终端的NPRACH,由此实现多终端在相同时频资源上的OCC复用发送,提高了资源利用率,且实现了上行链路容量增强(uplink capacity enhancement)和系统扩容,在有限的时频资源以及终端有限发送功率的前提下能够支持更多的终端进行上行传输,提高了上行传输效率。
可选地,在一些实施例之中,上述的NPRACH的OCC复用发送可以适用以下至少之一情形:
在随机接入过程(Normal RACH procedure)中进行NPRACH的OCC复用发送;
在数据提早传输(Early Data Transmission,EDT)中进行NPRACH的OCC复用发送;
在锚点载波(Anchor carrier)上进行NPRACH的OCC复用发送;
在非锚点载波(non-anchor carriers)上进行NPRACH的OCC复用发送;
在基于不同覆盖增强等级(Coverage Enchancement level,CE Level)通信时进行NPRACH的OCC复用发送。
基于此,在一些实施例之中,终端所上报的该OCC复用能力可以包括以下至少之一:
终端是否支持EDT;
终端是否支持在非锚点载波上进行NPRACH的传输;
终端是否支持OCC复用;
终端是否支持在EDT时进行OCC复用;
终端是否支持在非锚点载波上进行OCC复用;
终端是否支持在锚点载波上进行OCC复用。
可选地,在一些实施例之中,终端可以仅上报其是否支持OCC复用,此时,当终端支持OCC复用时,默认终端是支持在正常随机接入过程(Normal RACH procedure)中进行OCC复用,和/或,默认终端是支持在EDT时进行OCC复用,和/或,默认终端是支持在所有业务中均可以进行OCC复用。
可选地,在另一些实施例之中,终端可以向网络设备上报其是否支持EDT、和/或,是否支持在非锚点载波上进行NPRACH的传输,同时,终端还可以向网络设备上报其是否支持OCC复用。其中,当终端向网络设备上报该终端支持EDT,且支持OCC复用时,则认为终端支持在EDT时进行OCC复用,即:支持对EDT传输过程中的NPRACH进行OCC复用发送;或者,当终端向网络设备上报该终端支持在非锚点载波上进行NPRACH的传输,且支持OCC复用时,则认为终端支持在非锚点载波上进行OCC复用,即:支持对非锚点载波上的NPRACH进行OCC复用发送。
可选地,在又一些实施例之中,终端可以向网络设备直接上报该终端是否支持在EDT时进行OCC复用、和/或,终端是否支持在非锚点载波上进行OCC复用、和/或,终端是否支持在锚点载波上进行OCC复用。
可选地,在一些实施例之中,终端可以通过第一信令向网络设备上报终端的OCC复用能力,可选地,该第一信令例如可以包括以下至少之一:UE辅助信息(UE assistance information)信令、UE能力(UE capability)信令、无线资源控制(Ratio Resource Control,RRC)信令。
可选地,终端通过向网络设备上报该终端的OCC复用能力,以便网络设备可以基于该终端的OCC复用能力来为终端调度合适的资源,例如,当终端支持OCC复用时,网络设备可以向终端调度用于OCC复用的资源,当终端不支持OCC复用时,网络设备可以向终端调度用于非OCC复用的资源。或者,当终端在某个业务中支持OCC复用时,网络设备为该业务调度资源时可以调度用于OCC复用的资源,当终端在某个业务中不支持OCC复用时,网络设备为该业务调度资源时可以调度用于非OCC复用的资源,由此以实现对终端的准确和有效的管理,确保了对终端资源的合理管理和调度。
步骤2102、网络设备向终端发送配置信息。
可选地,该配置信息可以用于配置至少一个第一资源集和/或至少一个第二资源集;其中,该第一资源集可以包括一个或多个资源,该第一资源集中的一个或多个资源可以用于进行NPRACH的OCC复用发送,
该第二资源集可以包括一个或多个资源,该第二资源集中的一个或多个资源可以用于进行NPRACH的非OCC复用发送。
由上述内容可知,本公开实施例之中,会将“用于OCC复用的资源(即第一资源集)”与“用于非OCC复用的资源(即第二资源集)”相互独立开,由此可以避免OCC复用发送与非OCC复用发送之间的相互干扰,确保OCC复用发送与非OCC复用发送两者的通信效率和通信稳定性。
