实施例十五
在本实施例中,系统是TDD或FDD NB-IoT系统。
基站通过系统信息块消息给终端配置可用于传输消息1的资源列表以及资源列表对应的两个载波列表(表示为载波列表0和载波列表1,等价于两个载波集合);资源列表中的所有资源分布在载波列表0包含的载波范围内。
本实施例中,两个载波列表中每一个载波列表包括16个载波。
终端从资源列表中选择一个资源发送消息1。之后,终端利用载波列表1接收消息2和消息4及利用载波列表0发送消息3和消息5;基站利用载波列表1发送消息2和消息4及利用载波集合0接收消息3和消息5。
利用载波集合1发送消息2和消息4,包括:基站在载波列表1中的指定载波上发送下行分配NPDCCH数据,其中,指定载波是载波列表1中与接收消息1的资源相对应的载波,是基站通过系统信息块消息配置给终端的;下行分配NPDCCH数据用于调度消息2或消息4并且携带4比特指示载波列表1中传输消息2或消息4载波;然后,基站在传输消息2或消息4的载波上发送消息2或消息4;例如4比特为“0010”表示载波列表1中索引为2的载波是传输消息2或消息4的载波;在这种情况下,基站在载波列表1中索引为2的载波上发送消息2或消息4给终端。
利用载波集合1接收消息2和消息4,包括:终端在载波列表1中的指定载波上接收下行分配NPDCCH数据,其中,指定载波是载波列表1中与发送消息1的资源相对应的载波,是基站通过系统信息块消息配置给终端的;下行分配NPDCCH数据用于调度消息2或消息4且携带4比特指示载波列表1中传输消息2或消息4载波;然后,终端在传输消息2或消息4的载波上接收消息2或消息4;例如4比特为“0010”表示载波列表1中索引为2载波是传输消息2或消息4的载波;在索引为2的载波上接收消息2或消息4。
基站发送消息4之后还需接收对应消息4的HARQ-ACK反馈;基站在接收消息1的载波上接收HARQ-ACK反馈。终端接收消息4后还需发送对应消息4的HARQ-ACK反馈;在发送消息1的载波上发送HARQ-ACK反馈。
利用载波列表0发送消息3或消息5,包括:终端在载波列表1中的指定载波上接收上行授予NPDCCH数据,其中,指定载波是载波列表1中与发送消息1的资源相对应的载波,是基站通过系统信息块消息配置给终端的;上行授予NPDCCH数据用于调度消息3或消息5且携带4比特指示载波列表0中传输消 息3或消息5的载波;或者,终端获取消息2携带的用于调度消息3的上行授予信息,该上行授予信息包含4比特指示载波列表0中传输消息3的载波。然后,终端在传输消息3或消息5的载波上发送消息3或消息5;例如4比特为“0010”表示索引为2的载波是传输消息3或消息5的载波;终端在载波列表0中索引为2载波上发送消息3或消息5至基站。
利用载波列表0接收消息3或消息5,包括:基站在载波列表1中的指定载波上发送上行授予NPDCCH数据,其中,指定载波是载波列表1中与接收消息1的资源相对应的载波,是基站通过系统信息块消息配置给终端的;上行授予NPDCCH数据用于调度消息3或消息5且携带4比特指示载波列表0中传输消息3或消息5的载波;或者,基站通过消息2发送用于调度消息3的上行授予信息,上行授予信息包含4比特指示载波列表0中用于传输消息3的载波。然后,基站在传输消息3或消息5的载波上接收消息3或消息5;例如4比特为“0010”表示索引为2的载波是传输消息3或消息5的载波;基站在载波列表0中索引为2载波上接收消息3或消息5。
消息2(包括竞争消息2和非竞争消息2)或消息3或消息4或消息5只能在对应的时间窗范围内进行传输,所以消息2或消息3或消息4或消息5是延时敏感的;如果给定的消息2或消息3或消息4或消息5传输被其它采用不同或相同覆盖等级的消息2或消息3或消息4或消息5传输所阻塞时,无法通过延时调度给定的消息2或消息3或消息4或消息5解决阻塞问题;另外,如果消息2或消息3或消息4或消息5传输失败,终端需要重新发起消息1传输以重新尝试随机接入,从而更多的终端功耗和资源开销会被导致。在相关技术中,基站和终端利用固定载波传输消息2或消息3或消息4或消息5;上述方式导致了较多的阻塞问题,尤其是大量终端同时接入时。在上述实施例九至实施例十五中,基站和终端能够利用载波集合传输消息2、消息3、消息4和消息5中的一个或多个。上述实施例所示的方法避免或减轻了使用不同覆盖等级或相同覆盖等级的消息2、消息3、消息4和/或消息5传输之间的相互阻塞问题,最终减少了终端的功耗和避免了不必要的资源开销。
