- the narrowband has only 6 PRBs, and the control channel scheduling the first information transmission needs to occupy more resources or repeat the guarantee performance, it may be specified that the uplink grant is not detected in the search space of the control channel that schedules the first information transmission. This may not include the field, thereby saving the load of the first downlink control information.
- the first downlink control information may include: system information update indication information (English name systemInfoModification). For example, one bit may be used to indicate system information update in the first downlink control information. For example, if the first downlink control information indicates systemInfoModification, the UE considers that system information may have been updated. Of course, it is also possible to indicate in the first downlink control information which specific system information has been updated. For example, it may be a bitmap (English name bitmap) mode indication or a multi-bit joint indicating which system information has been updated.
- the first downlink control information may include: an alarm indication information of a seismic typhoon warning system (English name: Earthquake and Tsunami Warning System, English abbreviation: ETWS).
- ETWS can be indicated by 1 bit in the first downlink control information.

- CMAS Commercial Mobile Alert Service
- the CMAS can be indicated by 1 bit in the downlink control information.
- the first downlink control information may include: transport block size indication information of the first information transmission. If the transport block size of the first information transmission is determined according to other already indicated parameters, the field in the first downlink control information does not need to indicate the transport block size. Otherwise, the size of the transport block needs to be indicated in the first downlink control information, for example, the transport block size is indicated by 2 bits.
- the first downlink control information may include: the first information transmission Override enhanced transmission indication information.
- the coverage enhanced transmission indication information is coverage enhancement level information or repetition number information or bundle transmission size information. If the coverage enhancement transmission indication information of the first information transmission is determined according to the repetition level (or the number of repetitions) of the channel before the first information transmission, the first downlink control information does not need the coverage enhanced transmission indication information indicating the first information transmission.
- the channel before the first information transmission may be a random access preamble, or a control channel for scheduling a random access response, or a control channel for scheduling a paging message. Otherwise, the coverage enhancement indication information may be indicated by 1 to 3 bits.
- the number of repetitions of the first information may be the number of repetitions A plus the number of repetitions B.
- the number of repetitions A is the number of repetitions determined according to the coverage enhancement level or the number of repetitions of the high layer signaling configuration or a predetermined number of repetitions.
- the number of repetitions B is the number of repetitions indicated by the downlink control information. Therefore, the number of repetitions B indicated by the downlink control information can be regarded as a fine adjustment of the number of repetitions A. Of course, it is also the content of the present invention to replace the above repetition number with the bundle transmission size.
- the first downlink control information may include: indication information of the downlink control information format, and whether the downlink control information needs to be the control information for scheduling the first information, or the downlink control information carries the first information.
- Control information The distinguishing method includes, but is not limited to, a display field indication in the first downlink control information, such as a distinction using 1 bit, or a joint indication of format differentiation and authorization distinction using 2 bits.
- different control channel scrambling codes may also be used to distinguish whether the downlink control information is control information for scheduling the first information or the control information for carrying the first information for the downlink control information. For example, if the downlink control information carries the first information, the redesigned wireless network temporary identifier (English name: Radio Network Tempory Identity, RNTI) or the RNTI set is used, and the first information is scheduled for the downlink control information, and the existing information is used. RNTI.
- RNTI Radio Network Tempory Identity
- the downlink control information corresponding to the coverage enhancement level Y bears (ie, includes) the first information, and the downlink control information corresponding to the coverage enhancement level X schedules the first information.
- the number of repetitions required to cover the enhancement level X is generally less than the number of repetitions required to cover the enhancement level Y.
- the downlink control information corresponding to the coverage enhancement bears (ie, includes) the first information, and the downlink control information corresponding to the non-coverage enhancement schedules the first information.
- the first downlink control information may include: random access preamble indication information, and the indication information of the random access preamble may be a simplified random access preamble identifier (English name: Random Access Preamble IDentitfier, English abbreviation: RAPID).
- RAPID is used to identify the random access preamble randomly selected by the UE during the random access procedure.
- the existing LTE protocol supports 64 random access preambles on one PRACH resource, so the RAPID is required to indicate 6 bits.
- the coverage enhancement level (such as the coverage enhancement level is the repetition level or the number of repetitions) and the random access resources have a one-to-one mapping relationship.
- the number of bits indicating the RAPID may be lowered. For example, a total of 64 preambles support a total of three coverage enhancement levels. If the number of preambles of the three levels is approximately equal, one level can have 21 or 22 preambles. Then, only 5 bits are needed to indicate the preamble. Further, if the number of preambles assigned by a certain level is small, the number of bits required to indicate the preamble may be less. If the number of preambles assigned to a certain level is num_preamble, the number of bits required to indicate the RAPID corresponding to the PRACH group may be: The parentheses in the formula are rounded up.
- the base station may also implicitly indicate the received random access preamble, and the RAPID is not used in the random access response information or indicated by few bits.
- the wireless network temporary identity that now scrambles the random access response is determined according to the time index (subframe number) of the random access preamble transmission and the frequency resource index. Therefore, the wireless network temporary identifier can implicitly reflect the time index and the frequency resource index.
- the RNTI may implicitly indicate the number of the random access preamble or the random access preamble.
- the radio network temporary identifier of the scrambled random access response may indicate a random access preamble identifier.
- the random access response information may further indicate one of the two random access preambles by using one bit.
- the RNTI associated with the random access preamble can be configured by pre-defined or signaling. The association between the RNTI and the random access preamble may be pre-defined or signaled.
- one RNTI set or range is pre-defined, and each RNTI in the RNTI set or range is associated with the determined random access preamble.
- the preamble_id is the index of the preamble.
- N is the index number of the time resource
- M is the product of the number of indexes of the PRACH frequency resource and the number of indexes of the PRACH time resource.
- the PRACH time resource is in units of X subframes
- the PRACH time resource is a resource in Y radio frames
- the PRACH time resource is in units of X subframes
- each sub-frame can have random access resources, that is, there are 10 random access opportunities; and in the coverage-enhanced scene, even if the number of repetitions is 2, the maximum is There are also only 5 access opportunities. This can reduce the number of random access opportunities, that is, the number of RNTIs can be reduced.
- the index of the PRACH frequency resource and the number of indexes of the PRACH frequency resource may be independently numbered for each coverage enhancement level.
- the coverage enhancement level 1 has two PRACH frequency resources, the index is ⁇ 0, 1 ⁇ , the number of indexes of the PRACH frequency resource is 2, and the coverage enhancement level 2 has three PRACH frequency resources, and the indexes are respectively ⁇ 0, 1, 2 ⁇ , the number of indexes of the PRACH frequency resource is 3.
- the index of the PRACH frequency resource and the index number of the PRACH frequency resource may be multiple coverage enhancement level joint numbers.

- the number of indexes of the PRACH frequency resource may be determined independently by the frequency division duplex system and the time division duplex system, or may be determined according to the number of indexes of the largest PRACH frequency resource in the frequency division duplex system and the time division duplex system.
- the number of indexes of the PRACH frequency resources is equal to Max (F1, F2), where Max is the largest. Value function.
- the indication information of the random access preamble is used to indicate whether the base station detects a random access preamble.

Description
本发明实施例涉及通信领域,尤其涉及一种信息的传输方法和基站以及用户设备。
物联网是指通过部署具有一定感知、计算、执行和通信能力的各种设备,获取物理世界的信息,通过网络实现信息传输、协同和处理,从而实现人与物、物与物的互联的网络。简而言之,物联网就是要实现人与物、物与物的互联互通。可能的应用包括智能电网、智能农业、智能交通、以及环境检测等各个方面。
移动通信标准化组织第三代合作伙伴计划(英文全称:3rd Generation Partnership Project,英文简称:3GPP)正在针对物联网业务开展技术研究和标准优化工作。其主要的研究和优化方向是,成本降低和覆盖增强。成本降低方面,可以降低终端设备的工作带宽,比如限定终端设备的工作带宽为1.4MHz,是一个重要研究方向;覆盖增强方面,主要是针对处于地下室等路损较大的机器类型通信(英文全称:Machine Type Communication,英文简称:MTC)设备提供覆盖增强支持,使得上述处于特殊场景的设备能够接入网络获得服务,其中,信号重复传输是实现覆盖增强的方法之一。在信号重复的技术下,能够带来一定的覆盖增强,但是可能消耗更多的资源。如何在使用信号重复实现覆盖增强的情况下,提高资源利用率是一个需要解决的问题。
对于随机接入响应(英文全称:Random Access Response,英文简称:RAR)消息或寻呼消息,根据目前的协议,随机接入响应消息或寻呼消息是通过物理下行控制信道(英文全称:Physical Downlink Control Channel,英文简称:PDCCH)所调度的物理下行共享数据信道(英文全称:Physical downlink shared data channel,英文简称:PDSCH)传输的。用户设备(英文全称:User Equipment,英文简称:UE)需要先接收PDCCH,根据所接收的PDCCH中的控制信息的指示获取随机接入响应消息(或寻呼消息)的传输块大小(英文全称:Transport Block Size,英文简称:TBS),进而根据确定的TBS进行随机接入响应消息(或
寻呼消息)的接收。
在需要对于随机接入响应消息(或寻呼消息)进行覆盖增强传输的场景下,用户设备在接收随机接入响应消息(或寻呼消息)之前先要接收调度信息的控制信道,根据所接收的控制信道确定携带随机接入响应消息(或寻呼消息)的传输块大小,进而按照确定的传输块大小接收随机接入响应消息(或寻呼消息)。为了用户设备成功接收随机接入响应消息(或寻呼消息),控制信道需要很多次重复,随机接入响应消息(或寻呼消息)也需要很多次重复,从而了增加***的资源开销,降低了网络的资源利用率,也大大增加了用户设备的检测复杂度和功耗开销。

需要说明的是,在本发明实施例,第一下行控制信息信息可以包括前述描述中的一种指示信息或者多种指示信息,这些指示信息的具体实现方式可以参阅后续实施例中对第一下行控制信息信息的描述。
202、向UE发送第一下行控制信息,根据第一下行控制信息向UE发送第一信息。
在本发明实施例中,基站生成如上所述的精简的第一下行控制信息之后,该第一下行控制信息由基站发送给UE,UE通过接收到第一下行控制信息可以获取到第一下行控制信息对第一信息的调度指示,当基站根据第一下行控制信息向UE发送第一信息之后,UE可以根据第一下行控制信息对第一信息的调度指示接收到第一信息,该第一信息可以是随机接入响应消息或者寻呼消息。
具体的,在本发明的一些实施例中,若基站发送第一信息是通过第二下行控制信息来发送,且第一信息可以承载在第二下行控制信息中,为了降低UE盲检控制信道的复杂度,第一下行控制信息的负荷大小与第二下行控制信息的负荷大小相同。负荷大小是比特个数,或比特长度。即第一下行控制信息和第二下行控制信息具有相同的比特个数。需要说明的是,本发明实施例中,第二下行控制信息的设计方法可以与第一下行控制信息的设计方法相同或者相类似。
通过以上实施例对本发明的说明可知,首先基站确定第一下行控制信息,其中,第一下行控制信息包括如下信息中的至少一种:第一信息传输所用的窄带资源的指示信息、第一信息传输的调制编码方法指示信息、第一信息传输的跳频指示信息、第一信息传输的覆盖增强传输指示信息。第一信息包括:随机接入响应消息和/或寻呼消息。然后基站向UE发送第一下行控制信息,根据第一下行控制信息向UE发送第一信息。本发明实施例中,第一下行控制信息用于调度第一信息,该第一下行控制信息中只包括前述指示信息中的至少一种,因此第一下行控制信息具有更精简的结构,从而可以实现使用较少的资源来传输该第一下行控制信息,提高传输第一下行控制信息的资源利用效率,用户设备只需要检测精简的第一下行控制信息,可以降低用户设备检测信道的功耗开销。
上述实施例中从基站侧描述了信息的传输方法,接下来从基站的对端(用户设备)侧进行说明本发明提供的信息的传输方法,请参阅图3所示,本发明另一个实施例提供的信息的传输方法,可以包括如下步骤:
301、接收基站发送的第一下行控制信息。
在本发明实施例中,基站生成如上所述的精简的第一下行控制信息之后,该第一下行控制信息由基站发送给UE,UE接收基站发送的第一下行控制信息,然后触发执行步骤302。
302、从下行控制信息中获取到如下信息中的至少一种:第一信息传输所用的窄带资源的指示信息、第一信息传输的调制编码方法指示信息、第一信息传输的跳频指示信息、第一信息传输的覆盖增强传输指示信息。第一信息包括:随机接入响应消息和/或寻呼消息。
在本发明实施例中,UE接收基站发送的第一下行控制信息,UE接收到
的第一下行控制信息为基站精简的第一下行控制信息,该第一下行控制信息包括的内容相比于现有技术减少了,因此UE检测第一下行控制信息的资源开销就可以极大减少。具体的,UE接收到的简化的第一下行控制信息包括了如下信息中的至少一种:1)、第一信息传输所用的窄带资源的指示信息、2)、第一信息传输的调制编码方法指示信息、3)、第一信息传输的跳频指示信息、4)、第一信息传输的覆盖增强传输指示信息。其中,第一信息包括:随机接入响应消息和/或寻呼消息。需要说明的是,第一下行控制信息可以包括如上所述的四种信息的其中任意一种信息,或者任意两种信息,或者任意三种信息、或者包括全部的四种信息,其中,在第一下行控制信息中具体该包括哪一种信息或者哪些种信息具体可以由应用场景来决定。

在本发明的一些实施例中,第一下行控制信息除了包括前述的1)至4)中所示的指示信息的至少一种信息外,或,第一信息除了包括前述的1)至8)中所示的指示信息的至少一种信息外,本发明实施例提供的第一下行控制信息还包括如下三种信息中的至少一种:9)、***信息更新指示信息、10)、地震台风告警***的告警指示信息、11)、商业移动告警服务的告警指示信息。需要说明的是,第一下行控制信息可以包括如上所述的三种信息的其中任意一种信息,或者任意两种信息,或者包括全部的三种信息,其中,在第一下行控制信息中具体该包括哪一种信息或者哪些种信息具体可以由应用场景来决定。
在本发明的一些实施例中,第一下行控制信息还包括:与随机接入响应消息对应的一个或多个随机接入前导指示信息。当第一下行控制信息用于调度随机接入响应消息时,在第一下行控制信息中还需要包括一个或多个随机接入前导标识,一个或多个随机接入前导标识与随机接入响应消息相对应。
需要说明的是,在本发明实施例,第一下行控制信息信息可以包括前述描述中的一种指示信息或者多种指示信息,这些指示信息的具体实现方式可以参阅后续实施例中对第一下行控制信息信息的描述。
303、根据第一下行控制信息接收第一信息。
在本发明实施例中,UE通过接收到第一下行控制信息可以获取到第一下行控制信息对第一信息的调度指示。当基站根据第一下行控制信息向UE发送第一信息之后,UE可以根据第一下行控制信的调度指示接收第一信息。该第一信息可以是随机接入响应消息或者寻呼消息。
在本发明的一些实施例中,基站可以将第一信息承载在第二下行控制信息中传输,则UE通过检测第二下行控制信息可以获取到第一信息,为了降低UE盲检控制信道的复杂度,第一下行控制信息的负荷大小与第二下行控制信息的负荷大小相同。
通过以上实施例对本发明的说明可知,首先UE接收基站发送的第一下行控制信息,UE从第一下行控制信息中获取到如下信息中的至少一种:第一信息传输所用的窄带资源的指示信息、第一信息传输的调制编码方法指示信息、第一信息传输的跳频指示信息、第一信息传输的覆盖增强传输指示信息。第一信息包括:随机接入响应消息和/或寻呼消息,然后UE根据第一下行控制信息接收基站发送的第一信息。本发明实施例中,第一下行控制信息用于调度第一信息,该第一下行控制信息中只包括前述指示信息中的至少一种,因此第一下行控制信息具有更精简的结构,从而可以实现使用较少的资源来传输该第一下行控制信息,提高传输第一下行控制信息的资源利用效率,用户设备只需要检测精简的第一下行控制信息,可以降低用户设备检测信道的功耗开销。
为便于更好的理解和实施本发明实施例的上述方案,下面举例相应的应用场景来进行具体说明。
以随机接入响应的处理为例,在现有的LTE***的随机接入过程中,UE需要先发送随机接入前导。UE发送随机接入前导后,进而接收随机接入响应消息。基站在给UE的随机接入响应消息中包含一个或多个随机接入响应。随机接入响应中包含了随机接入前导标识符(英文全称:Random Access Preamble IDentitfier,英文简称:RAPID),例如,RAPID标识了基站发送的随机接入前
导。UE接收随机接入响应后,若随机接入响应中的RAPID所标识的随机接入前导就是UE发送的随机接入前导,则UE认为该随机接入响应就是基站对自己发送的随机接入前导的响应。在LTE***中,基站在给UE的随机接入响应消息是通过PDSCH承载的。UE需要先接收控制信道,根据所接收的控制信道中的控制信息的指示获取随机接入响应消息的传输块大小,进而根据确定的传输块大小进行随机接入响应消息的接收。
以寻呼消息的处理为例,现有的LTE***中,空闲态的UE需要监听寻呼消息以判断网络侧或基站是否寻呼了该UE。连接态的UE需要监听寻呼消息以判断***信息是否发生了更新。基站给UE发送的寻呼消息是通过数据信道承载,而该数据信道由控制信道进行调度。因此,UE监听寻呼消息时,需要先检测调度寻呼消息的控制信道。只有成功检测出控制信道,再根据控制信道的指示接收承载寻呼消息的数据信道。
对于空闲态的UE,一旦UE成功检测出承载寻呼消息的数据信道,UE需要将自己的寻呼UE(英文全称:Identity,英文简称:ID)与寻呼消息中携带的寻呼UE ID进行匹配,如果匹配成功,则UE认为网络侧或基站寻呼了该UE。否则,UE认为该寻呼消息没有寻呼UE。对于连接态的UE,一旦UE成功检测出承载寻呼消息的数据信道,UE需要看看寻呼消息中是否指示了***信息修改。
一个寻呼消息中可以包含一个或多个寻呼UE ID。因此,一个寻呼消息可以对一个或多个UE发起寻呼。如前所述,UE需要成功检测出控制信道和控制信道调度的寻呼消息后才能判断该寻呼消息是否寻呼了该UE或该寻呼消息是否指示了***消息发生更新。对UE而言,可能成功检测出控制信道和控制信道调度的寻呼消息,但是发现该寻呼消息没有寻呼该UE或该寻呼消息没有指示***信息更新。这样UE白白消耗了很多功耗。特别是对于低成本或低复杂的UE而言,功耗问题更是至关重要。
在如上实现的随机接入过程以及寻呼过程中,都可以执行本发明实施例提供的信息的传输方法。基站对调度第一信息的第一下行控制信息进行简化设计。接下来举例进行说明。本发明实施例提供了一种传输下行控制信息及第一信息传输的方法,其中第一信息是随机接入响应消息和/或寻呼消息,第一信息的传输由第一下行控制信息进行调度。本发明实施例主要解决了第一下行控
制信息调度第一信息时,第一下行控制信息具体包含哪些内容。
在本发明的一些实施例中,第一下行控制信息可以包括:第一信息传输所用的窄带资源的指示信息。考虑到覆盖增强或对低复杂度或低成本UE的支持,***中可能会划分出一些窄带资源用于覆盖增强传输或为低复杂度(或低成本)UE服务。窄带资源或窄带是一个特定的频率资源,窄带资源可以由一个或多个资源块构成,或者由一个或多个子载波构成。其中,低复杂(或低成本)UE只能同时在一个窄带上接收和/或发送信息。因此,第一信息也只能在一个窄带上进行传输。第一下行控制信息可以包含指示第一信息传输所在的窄带资源。例如指示窄带资源所需要的比特(英文:bit)数目为:log2(floor(NDLRB/6)或floor(log2(NDLRB/6)),或ceil(log2(NDLRB/6))。公式中以6个物理资源块(英文全称:Physical Resource Block,英文简称:PRB)组成一个窄带为例。如果窄带大小为n,则该字段所需bit可以为:log2(floor(NDLRB/n))或floor(log2(NDLRB/n)),或ceil(log2(NDLRB/n))。其中NDLRB是以PRB为单位的下行带宽。比如1.4MHz的带宽,有6个PRB。20MHz带宽有100个PRB,因此可以划分为16个窄带,则需要4比特指示即可。floor函数表示向下取整,ceil函数表示向上取整。或者指示窄带资源所需要的bit数目为:floor(log2(M))或ceil(log2(M)),其中,M是基站配置的窄带个数。
在本发明的一些实施例中,第一下行控制信息可以包括:第一信息传输所用的窄带内的资源分配指示信息。以窄带包括6个PRB为例,窄带内的资源分配指示了6PRB窄带的位置,即窄带内的资源分配具体指示了窄带中的6个PRB中的具体的哪几个PRB用于随机接入响应传输。对窄带内的资源分配指示信息需要的比特举例如下:如果第一信息传输占用了窄带的全部PRB,则该字段可以省略,例如,可以用6比特按照位图指示的方式进行6个PRB的指示。为了降低指示的比特个数,可以限定第一信息传输占用的PRB数和可能的PRB位置。例如假设窄带包括的PRB的索引分别为:PRB n,PRB n+1,PRB n+2,PRB n+3,PRB n+4,PRB n+5。限制第一信息传输只占用2个PRB、4个PRB、6个PRB。如下表1所示,示意了一种用3比特指示传输所用的窄带资源的方法。可以理解的是,如下表1只是举例说明,窄带内资源指示比特状态与窄带内资源指示的对应关系还可以变换。
如下表2所示,示意了一种用2比特指示传输所用的窄带资源的方法。
需要说明的是,本发明实施例中表1和表2的表格中的窄带内资源指示比特状态与窄带内资源指示的对应关系只是示例性地,实际上窄带内资源指示比特状态与窄带内资源指示的对应关系可以变换。只要用比特为控制信道传输指示了窄带内的2个RB、4个RB、6个RB的资源分配,或用比特为控制信道的传输指示了窄带内的4个RB、6个RB的资源分配均可,而不需要局限于上述表格所示。
在本发明的一些实施例中,第一下行控制信息可以包括:第一信息传输的调制编码方法指示信息,可以根据支持的调制编码方式数量确定该字段所需要的bit。比如,如果支持固定的调制编码方式,或者调制编码方式根据其它信息隐含确定,则可以不包括该字段。例如可以用2~4比特指示调制编码方法。
在本发明的一些实施例中,第一下行控制信息可以包括:第一信息传输的
跳频指示信息。用于指示第一信息传输的跳频配置。如果传输的第一信息总是跳频,或者传输第一信息总是不跳频,或者按照预先规定或预先配置跳频,则可以不包括该字段。可以用0~2比特指示跳频配置。
在本发明的一些实施例中,第一下行控制信息可以包括:授权区分指示信息,用于上行授权和下行授权的区分指示。如果UE在调度第一信息传输的控制信道的搜索空间内还要检测下行控制信息是否是用于上行调度,而且上行调度的下行控制信息大小和调度第一信息的下行控制信息大小相同,那么需要1个比特指示上行授权和下行授权。如果UE在调度第一信息传输的控制信道的搜索空间内的控制信道不用于上行调度,那么不需要这个字段区分上行授权和下行授权。考虑到窄带只有6个PRB,且调度第一信息传输的控制信道需要占用较多的资源或通过重复保证性能,可以规定在调度第一信息传输的控制信道的搜索空间内不检测上行授权。这样可以不包括该字段,从而节省了第一下行控制信息的负荷大小。
在本发明的一些实施例中,第一下行控制信息可以包括:***信息更新指示信息(英文名称systemInfoModification)。如第一下行控制信息中可以用1个比特指示***信息更新。例如,如果第一下行控制信息指示了systemInfoModification,则UE认为***信息可能发生了更新。当然,还可以在第一下行控制信息中指示具体哪些***信息发生了更新。例如可以是位图(英文名称bitmap)方式指示或者多比特联合指示哪些***信息发生了更新。
在本发明的一些实施例中,第一下行控制信息可以包括:地震台风告警***(英文全称:Earthquake and Tsunami Warning System,英文简称:ETWS)的告警指示信息。如第一下行控制信息中可以用1个比特指示ETWS。
在本发明的一些实施例中,第一下行控制信息可以包括:商业移动告警服务(英文全称:Commercial Mobile Alert Service,英文简称:CMAS)的告警指示信息。如下行控制信息中可以用1个比特指示CMAS。
在本发明的一些实施例中,第一下行控制信息可以包括:第一信息传输的传输块大小指示信息。如果第一信息传输的传输块大小是根据其它已经指示的参数确定的,则第一下行控制信息中不需要字段指示传输块大小。否则第一下行控制信息中需要指示传输块的大小,例如,采用2比特指示传输块大小。
在本发明的一些实施例中,第一下行控制信息可以包括:第一信息传输的
覆盖增强传输指示信息。覆盖增强传输指示信息是覆盖增强等级信息或重复次数信息或捆绑传输大小信息。如果第一信息传输的覆盖增强传输指示信息是根据第一信息传输之前的信道的重复级别(或重复数量)确定,则第一下行控制信息不需要指示第一信息传输的覆盖增强传输指示信息。第一信息传输之前的信道可以是随机接入前导,或调度随机接入响应的控制信道,或调度寻呼消息的控制信道。否则可以用1~3比特指示覆盖增强传输指示信息。第一信息的重复次数可以由重复次数A加上重复次数B。其中重复次数A是根据覆盖增强等级确定的重复次数或者高层信令配置的重复次数或者预先规定的重复次数。重复次数B是下行控制信息指示的重复次数。因此,下行控制信息指示的重复次数B可以看做是对重复次数A的一个微调。当然,把上述重复次数替换为捆绑传输大小,同样是本发明的内容。
在本发明的一些实施例中,第一下行控制信息可以包括:下行控制信息格式的区分指示信息,需要区分下行控制信息是调度第一信息的控制信息,还是下行控制信息承载第一信息的控制信息。区分方法包括但不限于:第一下行控制信息中的显示字段指示,如使用1bit进行区分,或者用2比特进行格式区分和授权区分的联合指示。
在本发明的一些实施例中,还可以使用不同的控制信道扰码区分下行控制信息是调度第一信息的控制信息,还是下行控制信息承载第一信息的控制信息。比如,对于下行控制信息承载第一信息,使用重新设计的无线网络临时标识(英文全称:Radio Network Tempory Identity,英文简称:RNTI)或RNTI集合,对于下行控制信息调度第一信息,使用现有的RNTI。
或者根据覆盖增强等级或信道质量隐含确定下行控制信息的内容或功能。比如,覆盖增强等级Y对应的下行控制信息承载(即包含)了第一信息,覆盖增强等级X对应的下行控制信息调度了第一信息。通常覆盖增强等级X需要的重复次数小于覆盖增强等级Y需要的重复次数。再如,覆盖增强对应的下行控制信息承载(即包含)了第一信息,非覆盖增强对应的下行控制信息调度了第一信息。
在本发明的一些实施例中,第一下行控制信息可以包括:随机接入前导指示信息,随机接入前导的指示信息可以是简化的随机接入前导标识(英文全称:Random Access Preamble IDentitfier,英文简称:RAPID)。RAPID用于标识在
随机接入过程中UE随机选择的随机接入前导。现有LTE协议支持在一个PRACH资源上有64个随机接入前导,所以指示RAPID需要6比特。在覆盖增强场景下,覆盖增强等级(如覆盖增强等级是重复级别或重复次数)和随机接入资源存在一一对应的映射关系。上述对应关系如果是基于前导分组与覆盖增强等级一一对应的,则指示RAPID的比特数可能降低。比如,总共64个前导,总共支持三个覆盖增强等级,三个等级的前导数量近似均分的话,一个等级可以有21或22个前导,那么,只需要5bit来指示前导即可。进一步地,如果某个等级分配的前导数量很少的话,则指示前导需要的bit可以更少。如果记某个等级分配的前导数量为num_preamble,那么,该PRACH组对应的指示RAPID需要的比特数可以为:公式中的括号为向上取整。
此外,基站还可以隐式指示接收到的随机接入前导,随机接入应答信息中不用或者用很少的比特指示RAPID。例如现在加扰随机接入响应的无线网络临时标识根据随机接入前导传输的时间索引(子帧号)和频率资源索引确定的。因此无线网络临时标识可以隐含地体现出时间索引和频率资源索引。类似地,如果RNTI根据随机接入前导的索引确定,则RNTI可以隐含地指示随机接入前导或随机接入前导的编号。例如,假设有64个RNTI,其中每一个RNTI都与一个随机接入前导对应,则加扰随机接入响应的无线网络临时标识可以指示随机接入前导标识。再如,假设有32个RNTI,其中每一个RNTI都与两个随机接入前导对应,则随机接入应答信息中还可以用一个比特进一步指示上述两个随机接入前导中的一个随机接入前导。可以通过预先规定或者信令配置与随机接入前导关联的RNTI。RNTI与随机接入前导的关联关系可以是预先规定或者信令配置的。例如,预先规定一个RNTI集合或范围,该RNTI集合或范围中的每个RNTI都与确定的随机接入前导关联。再如,可以预先规定RNTI与随机接入前导索引的函数关系。即RNTI=function(t_id,f_id,preamble_id)或者RNTI=function(preamble_id),这里t_id是PRACH时间资源(一个或者多个无线帧内)的索引。f_id是PRACH频率资源的索引。preamble_id是前导的索引。具体地,一种函数关系为RNTI=1+t_id+N*f_id+M*preamble_id,其中,N、M是预先固定的常数。例如N是时间资源的索引数,M是PRACH频率资源的索引个数和PRACH时间资源的索引个数的乘积。
如时间资源是以子帧为单位,则一个无线帧最多有10个子帧可发送前导,
即N=10。如PRACH时间资源是以X个子帧为单位,则一个无线帧最多有ceil(10/X)个时间资源发送前导,这里ceil是向上取整,即N=ceil(10/X)。如果PRACH时间资源是在Y个无线帧内的资源,PRACH时间资源是以X个子帧为单位,则Y个无线帧最多有ceil(Y*10/X)个时间资源发送前导,即N=ceil(Y*10/X)。例如,在覆盖增强场景下,前导的发送需要重复,所以,同样时间内随机接入机会就会少很多。比如,同样是10ms的一个子帧,按照原有协议最多可以每个子帧都有随机接入资源,也就是有10个随机接入机会;而在覆盖增强场景下,即使重复次数为2,最多也只有5个接入机会。这可以减少随机接入机会数量,也就是可以减少RNTI的数目。
PRACH频率资源的索引和PRACH频率资源的索引个数可以是每个覆盖增强级别独立编号的。如覆盖增强级别1有2个PRACH频率资源,索引分别为{0,1},PRACH频率资源的索引个数是2;覆盖增强级别2有3个PRACH频率资源,索引分别为{0,1,2},PRACH频率资源的索引个数是3。PRACH频率资源的索引和PRACH频率资源的索引个数可以是多个覆盖增强级别联合编号的。如覆盖增强级别1有2个PRACH频率资源,索引分别为{0,1},覆盖增强级别2有3个PRACH频率资源,索引分别为{2,3,4},PRACH频率资源的索引个数是5。再如PRACH频率资源的索引个数可以是频分双工***和时分双工***独立确定的,或者按照频分双工***和时分双工***中最大的PRACH频率资源的索引个数确定的。如,频分双工***中最多有F1个PRACH频率资源,时分双工***中最多有F2个PRACH频率资源,则PRACH频率资源的索引个数等于Max(F1,F2),这里Max是取最大值函数。
在本发明的一些实施例中,随机接入前导的指示信息用于指示基站是否检测到随机接入前导。如可以通过位图指示随机接入前导的指示信息。比特串中的每一个比特对应指示了基站是否收到了一个或多个随机接入前导。例如,一个PRACH资源组内包括16个前导,可以用16个比特按照位图指示的方法指示基站是否检测到随机接入前导,其中,每一位比特对应指示一个随机接入前导。
需要说明的是,通常只有第一下行控制信息是调度寻呼消息时,第一下行控制信息中可以包括***信息更新的指示,地震台风告警***指示,商业移动告警服务指示中的一种或多种指示。当第一下行控制信息调度随机接入响应消
息时,第一下行控制信息中可以包括一个或多个随机接入前导标识。第一下行控制信息包含的随机接入前导标识个数是已知或者信令指示的,如下行控制信息内指示。如果为了保持调度随机接入响应传输(或寻呼消息传输)的第一下行控制信息与承载随机接入响应传输(或寻呼消息传输)的第二下行控制信息具有相同的大小,需要对调度随机接入响应传输(或寻呼消息传输)的第一下行控制信息包含的比特进行扩展,以使调度随机接入响应传输(或寻呼消息传输)的第一下行控制信息包含的比特数与承载随机接入响应传输(或寻呼消息传输)的第二下行控制信息包含的比特数相同。可以对上述调度随机接入响应传输(或寻呼消息传输)的第一下行控制信息包含的比特进行扩展形成最终的第一下行控制信息。比特扩展的方法包括以下的一种或多种:
重复第一下行控制信息的全部字段或部分字段,其中,重复可以是整数倍重复或非整数倍重复,另外,还可以在第一下行控制信息中补零或加填充比特。或者,把多个第一下行控制信息中每个第一下行控制信息的(全部或部分)内容级联在一起形成最终的第一下行控制信息,其中每个第一下行控制信息关联调度一个消息。多个第一下行控制信息中的不同第一下行控制信息可以为不同UE调度消息也可以为相同UE调度消息。其中,对第一下行控制信息中的比特进行编码,将编码后的比特做为最终下行控制信息包含的原始比特。如上述编码为里德-所罗门(英文全称:Reed-Muller,英文简称:RM)编码编码或里德穆勒(英文全称:Reed-Solomon,英文简称:RS)编码。
当然,第一下行控制信息包含的字段类型与第一下行控制信息调度的信息类型无关。例如,第一下行控制信息调度随机接入响应消息时第一下行控制信息包含的字段类型,与第一下行控制信息调度寻呼消息时第一下行控制信息包含的字段类型相同。另外需要说明的是,可以根据隐式的方式确定第一下行控制信息是否调度了第一信息。如对于覆盖增强(如重复传输)等级X,确定第一下行控制信息调度了第一信息。对于覆盖增强等级Y,确定第一下行控制信息不调度第一信息。通常覆盖增强等级X需要的重复次数小于覆盖增强等级Y需要的重复次数。
