Definitions

  • the present invention relates to the field of communications technologies, and in particular, to a timing method and related device for discontinuous transmission.
  • the cell forward access channel is a connection state configured by the user equipment (UE), which is also called an access state. In the connection state, there is a comparison between the network and the UE. Small transmission requirements for transmitting smaller packets.
  • the network In the CELL_FACH state, the network has only a total of 32 Common E-DCH resources.
  • the Common E-DCH is a resource required for the UE to transmit uplink signals in the CELL_FACH state. The UE cannot be occupied for a long time.
  • the UE has a timer, and during the timer period, there is no uplink E-DCH or HS-DPCCH transmission, and the timer continues to count. After the timer reaches the threshold, the UE will actively release the Common E-DCH resource, so that other UEs can obtain the Common E-DCH resource.
  • the DTX technology under CELL_FACH is being discussed in the standard, so that when the UE is in the CELL_FACH state, the DPCCH can be intermittently transmitted, thereby reducing the uplink interference caused by the DPCCH and saving the power overhead of the UE.
  • the UE's DTX configuration in the CELL_FACH state is different from the DTX configuration of the UE in the CELL_DCH state because the UE occupies the Common E-DCH resource for a short period of time.
  • the transmission process of the UE in the CELL_FACH state is as shown in FIG. 1. The timer starts when the UE turns off the transmitter, and the duration of the UE to turn off the transmitter is timed. If the timer is longer than the threshold, the UE releases the Common E- DCH resources. In the transmission process shown in Figure 1, the lengths of the DPCCH Preamble and DPCCH Postamble are fixed and relatively short.
  • the UE If the UE turns off the transmitter for too long and does not release in the CELL_FACH state.
  • the Common E-DCH resource is used, uplink synchronization cannot be performed in time to control the UE's transmit power. If the UE turns off the uplink transmitter for a long time, it starts to transmit the uplink signal because the time interval between the previous transmission and the current transmission is long, resulting in a large offset of the channel condition, the timing deviation between the UE and the base station. Because the base station cannot know the offset, the base station cannot accurately perform uplink synchronization on the UE's transmit signal.

Description

非连续发射的定时方法及相关设备 技术领域
本发明涉及通信技术领域，尤其涉及一种非连续发射的定时方法及相关设备。
背景技术
小区前向接入信道(CELL_FACH，Cell Forward Access Channel)是网络为终端(User Equipment，UE)配置的一种连接状态，也称为接入态，该连接状态下，网络与UE之间有较小的传输需求，用于传输较小的数据包。CELL_FACH状态下，网络一共只有32个共用的(Common)E-DCH资源，Common E-DCH是UE在CELL_FACH状态下发射上行信号时需要的一种资源，UE不能长时间占用。通常，UE有一个定时器，定时器计时期间，没有上行E-DCH或HS-DPCCH发射，则定时器继续计时。定时器到达门限值后，UE会主动释放Common E-DCH资源，以便其它UE能够获得Common E-DCH资源。
目前，标准上正在讨论CELL_FACH下的DTX技术，以便UE处于CELL_FACH状态下时，能够间断发射DPCCH，达到减少DPCCH带来的上行干扰，节约UE的功率开销的目的。
因为UE占用Common E-DCH资源的时间较短，所以CELL_FACH状态下UE的DTX配置与CELL_DCH状态下UE的DTX配置不同。CELL_FACH状态下UE的传输过程如图1所示，定时器开始于UE关闭发射机的时刻，对UE关闭发射机的时长进行计时，如果定时器的计时时长大于门限值，UE释放Common E-DCH资源。图1所示的传输过程中，DPCCH Preamble、DPCCH Postamble的长度都是固定的，而且比较短。
如果CELL_FACH状态下UE关闭发射机的时长过长，且没有释放 Common E-DCH资源时，无法及时做到上行同步，控制UE的发射功率。如果UE关闭上行发射机较长时间之后，开始发射上行信号，因为之前一次发射与本次发射之间的时间间隔较长，导致信道条件、UE和基站之间的定时偏差产生较大的偏移，由于基站无法获知该偏移，导致基站无法准确地对UE的发射信号进行上行同步。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明实施的应用场景为UE的DTX，所应用的系统如图2所示，包括UE201和基站202。具体地，UE在CELL_FACH状态下进行DTX。基站接收处于CELL_FACH状态下的UE的DTX的上行信号。该系统中还可能包括无线网络控制器(Radio Network Controller，RNC)203，RNC用于为UE和基站配置上行信号发射和接收的相关参数。
本发明实施例可以应用于WCDMA、LTE、TDSCDMA中的DTX技术。尤其适用于CELL_FACH状态下UE的DTX。
本发明实施例中DPCCH前导码为提前于上行信号(如E-DCH、HS-DPCCH等)发射的符号序列，该符号序列一般用于上行同步和信道估计，DPCCH前导码可以是DPCCH本身。
第一实施例
RNC配置UE的连接状态为CELL_FACH状态，以及用于为终端和基站配置计时区间与DPCCH前导码的属性之间的对应关系。UE确定计时时长对应的计时区间，按照该计时区间对应的DPCCH前导码的属性发送DPCCH前导码。基站确定计时时长对应的计时区间，采用该计时区间对应的DPCCH前导码的属性接收DPCCH前导码。其中，DPCCH前导码的属性包括DPCCH前导码序列的长度和/或DPCCH前导码序列的组成方式。
应用中，计时区间与DPCCH前导码的属性之间的对应关系可以是基站和终端预先约定的。可选地，计时区间与DPCCH前导码的属性之间的对应关系可以由RNC配置给UE和基站。
本发明实施例中，针对UE的DTX过程中，UE与基站之间的上行同步问题，尤其是处于CELL_FACH状态下的UE，提出了如图3所示的非连续发射的定时方法，需要说明的是，该方法并不仅限于处于CELL_FACH状态下的UE，也可以适用于处于CELL_DCH状态下的UE，具体如下。
步骤301：UE确定需要发射上行信号的时刻距离计时起点的时长。
具体地，UE在计时起点启动定时器，获取定时器在发射上行信号的时刻的计时时长，即为发射上行信号的时刻距离计时起点的时长。
一个具体实施中，计时起点为预设值，该预设值可以是由基站和UE通过协议约定，或者由网络侧(如RNC)为UE和基站配置的。
另一个具体实施中，计时起点由以下任意一种触发事件确定：下行同步成功的时间点、后校验(Post Verification，PV)开始或者成功结束的时间点、PV成功结束后的预定义时间点、PV成功结束后DPCCH停止发射的时间点、E-DCH开始发射或结束发射的时间点、确认有数据需要发射的时间点、确认数据发射结束的时间点、与E-DCH相关的DPCCH开始发射或结束发射的时间点、HS-DPCCH开始发射或结束发射的时间点、与HS-DPCCH相关的DPCCH开始发射或结束发射的时间点。
步骤302：UE根据距离计时起点的时长以及预设门限，确定需要发射的上行信号对应的DPCCH前导码的属性。
实施中，UE根据至少一个第一预设门限，将从计时起点到第二预设门限的时长划分为至少两个时长区间，其中，每个时长区间各自对应一个DPCCH前导码的属性。具体地，不同的时长区间对应的DPCCH前导码的属性不相同。
具体地，第二预设门限为UE从计时起点到UE释放占用的Common E-DCH资源的时长。
实施中，UE确定距离计时起点的时长所属的时长区间，获取确定的该时长区间对应的DPCCH前导码的属性，将获取的DPCCH前导码的属性确定为需要发射的上行信号对应的DPCCH前导码的属性。
具体地，第一时长区间对应的DPCCH前导码的长度，小于第二时长区间 对应的DPCCH前导码的长度，其中，第一时长区间内的每个值小于第二时长区间内的每个值。和/或，第一时长区间对应的DPCCH前导码序列的组成方式，与第二时长区间对应的DPCCH前导码序列的组成方式不相同。
在一个具体实施中，在仅有一个第一预设门限的情况下，该第一预设门限将计时起点到UE释放占用的Common E-DCH资源的时长划分为两个时长区间，即第一时长区间和第二时长区间，第一时长区间对应的DPCCH前导码的长度小于第二时长区间对应的DPCCH前导码的长度，其中，第一时长区间内的每个值小于第二时长区间内的每个值。

具体地，UE在发射上行信号之前的X个时隙开始发射DPCCH前导码，其中，X为大于1的正整数。可选地，X等于DPCCH前导码的长度。应用中，X可以有由RNC配置给UE和基站。
具体的，UE先发DPCCH前导码。发完DPCCH前导码后，立即发数据和DPCCH，数据和DPCCH是同时发射的。DPCCH前导码的时隙格式可以与DPCCH的时隙格式相同。
可选地，UE在DPCCH前导码的属性对应的预设时间位置处发射上行信号。具体地，预设时间位置为在定时边界的基础上增加预设的时间偏置得到。其中，定时边界包括下行无线帧边界、上行无线帧边界、上行E-DCH数据TTI边界中的任意一种。其中，定时边界可以是周期性出现，例如每间隔Y个TTI出现一次定时边界，Y是基站配置给UE和基站的参数。
实施中，UE在计时起点启动定时器后，在达到第一预设门限之前，可以重新启动该定时器，重新启动该定时器的时间点可以是预设值，该预设值为UE和基站通过协议约定的，或者为网络侧(如RNC)配置给UE和基站的。重新启动该定时器的时间点也可以是以下任意一种：E-DCH开始发射或结束发射的时间点、确认有数据需要发射的时间点、确认数据发射结束的时间点、 与E-DCH相关的DPCCH开始发射或结束发射的时间点、HS-DPCCH开始发射或结束发射的时间点、与HS-DPCCH相关的DPCCH开始发射或结束发射的时间点。
步骤304：基站确定当前时刻距离计时起点的时长。
其中，计时起点的具体取值参见以上描述。
步骤305：基站根据距离计时起点的时长以及预设门限，确定终端UE发射的DPCCH前导码的属性。
具体地，基站根据至少一个第一预设门限，将所述计时起点至第二预设门限的时长划分为至少两个时长区间；所述基站确定所述距离所述计时起点的时长所属的所述时长区间，获取确定的所述时长区间对应的DPCCH前导码的属性。
其中，第一时长区间对应的DPCCH前导码的长度，小于第二时长区间对应的DPCCH前导码的长度，其中，所述第一时长区间内的每个值小于所述第二时长区间内的每个值。和/或，第一时长区间对应的DPCCH前导码序列的组成方式，与第二时长区间对应的DPCCH前导码序列的组成方式不相同。
其中，第二预设门限为从所述计时起点到所述UE释放占用的共用的增强专用信道资源的时长。
实施中，至少一个第一预设门限、第二预设门限、每个所述时长区间各自对应的DPCCH前导码的属性，由网络侧配置给所述基站。例如，RNC为基站配置第一预设门限、第二预设门限、每个所述时长区间各自对应的DPCCH前导码的属性。其中，第一预设门限的具体取值参见以上描述。
需要说明的是，第一预设门限、第二预设门限、每个时长区间各自对应的DPCCH前导码的属性，需要基站与终端理解一致。
步骤306：基站按照确定的所述DPCCH前导码的属性接收DPCCH前导码。

该实施例中，终端根据计时时长以及预设门限，确定需要发射的上行信号对应的DPCCH前导码的属性，按照确定的DPCCH前导码的属性发射DPCCH前导码，使得在UE长时间关闭发射机后启动上行信号传输时，能够发射较优的DPCCH的前导码，使得基站能够进行上行同步。如果UE仅仅是短时间关闭发射机后启动上行信号传输，仍然可以采用之前的DPCCH前导码，从而解决了UE的非连续发射的上行同步问题。
尤其是，终端根据计时时长以及预设门限，确定需要发射的上行信号对应的DPCCH前导码的长度，按照确定的DPCCH前导码的长度发射DPCCH前导码，使得在UE长时间关闭发射机后启动上行信号传输时，能够发射较长的DPCCH的前导码，使得基站能够有足够的DPCCH前导码进行上行同步。如果UE仅仅是短时间关闭发射机后启动上行信号传输，仍然可以采用较短的DPCCH前导码，从而解决了UE的非连续发射的上行同步问题。
第二实施例
RNC为UE和基站配置上行信号与预设时间位置之间的对应关系，UE按照配置的预设时间位置发射上行信号，基站按照配置的预设时间位置接收上行信号。
本发明实施例中，针对UE的DTX过程中，UE与基站之间的上行同步问题，尤其是处于CELL_FACH状态下的UE，提出了如图4所示的非连续发射的定时方法，需要说明的是，该方法并不仅限于处于CELL_FACH状态下的UE，也可以适用于处于CELL_DCH状态下的UE，具体如下：
步骤401：UE确定需要发射的上行信号对应的预设时间位置。
优选地，所述预设时间位置为在定时边界的基础上增加预设的时间偏置 得到，所述定时边界包括下行无线帧边界、上行无线帧边界、上行E-DCH数据TTI边界中的任意一种。其中，定时边界可以为周期性出现的。
步骤402：UE在所述预设时间位置处发射所述上行信号。
具体地，不同的上行信号对应不同的预设时间位置。
例如，如果UE需要发射DPCCH，该DPCCH包括DPCCH前导码，则需要在该DPCCH对应的预设时间位置处开始发射；如果UE需要发射E-DCH数据信道，则需要在该E-DCH数据信道对应的预设时间位置处开始发射，E-DCH数据信道可以是E-DPDCH或者E-DPCCH。
优选地，DPCCH对应的预设时间位置，比E-DCH数据信道对应的预设时间位置提前X个时隙，可以实现在发送E-DCH数据信道之前发送X个时隙的DPCCH前导码，帮助基站获取上行同步。
相应地，基站定时接收终端发送的上行信号的过程如下：
步骤403：基站确定终端发射上行信号对应的预设时间位置。
其中，基站侧配置的上行信号对应的预设时间位置，与终端侧配置的上行信号对应的预设时间位置一致。
步骤404：基站在所述预设时间位置处接收所述上行信号。
其中，上行信号包括DPCCH前导码和上行数据中的任意一个或全部。
其中，上行信号对应的预设时间位置可以由网络侧配置给UE和基站，可以是由UE与基站相互约定。
该实施例中，UE的发射机在与基站约定的预设时间位置处开始发射上行信号，提高了基站上行同步的性能。
以下通过三个具体实施例对处于CELL_FACH状态下的UE的DTX的定时过程进行举例说明。
第一具体实施例
如图5所示，假设处于CELL_FACH状态下的UE配置了DTX，且该UE在每次上行信号发射完毕之后，关闭发射机并启动定时器，该定时器有两个门限，即门限一和门限二，其中门限一的值小于门限二的值。
如果在定时器开始计时的时刻与门限一之间，UE有E-DCH和/或HS-DPCCH要发射，则使用长度为x1的DPCCH前导码，以及使用长度为x2的DPCCH Postamble。如果在门限一和门限二之间，UE有E-DCH和/或HS-DPCCH要发射，则使用长度为y1的DPCCH前导码，以及使用长度为y2的DPCCH Postamble。
其中，x1、x2、y1、y2的长度单位包括但不限于时隙、传输时间间隔(Transmit Time Interval，TTI)、帧、毫秒等。
通常配置x1<y1，x2＝y2。
具体地，RNC通过RRC信令通知UE以下参数中的任意一个或多个：门限一的值、门限二的值、x1、x2、y1、y2。或者，基站通过HS-SCCH命令对UE配置以下参数中的任意一个或多个：门限一的值、门限二的值、x1、x2、y1、y2。
具体地，网络侧可以在UE获取Common E-DCH资源后为UE配置以上参数，或者，网络侧通过广播的方式广播以上参数，小区下收到该广播的UE均采用广播的以上参数。
其中，门限二的值为定时器从计时起点到UE释放占用的Common E-DCH资源的时长。
该第一具体实施例，通过在图3中已有的定时器的基础上，增加一个门限，即门限一，通过门限一将定时器的计时周期划分为两个时长区间，每个时长区间对应的DPCCH前导码的长度不相同，每个时长区间对应的DPCCH Postamble可以相同，从而可以实现在UE长时间关闭发射机后启动上行传输时，发射较长的DPCCH前导码，使得网络侧有足够的DPCCH前导码进行上行同步，并且如果UE仅是短时间关闭发射机后启动上行传输，依然可以采用较短的DPCCH前导码。
第二具体实施例
在图1所示的定时器的基础上，引入一个新的定时器。假设处于CELL_FACH状态下的UE配置了DTX，在新引入的定时器未超过门限时， 如果UE有E-DCH和/或HS-DPCCH要发射，则使用长度为x1的DPCCH前导码，以及使用长度为x2的DPCCH Postamble。在新引入的定时器超过门限值时，如果UE有E-DCH和/或HS-DPCCH要发射，则使用长度为y1的DPCCH前导码，以及使用长度为y2的DPCCH Postamble。
其中，x1、x2、y1、y2的长度单位包括但不限于时隙、传输时间间隔(Transmit Time Interval，TTI)、帧、毫秒等。
通常配置x1<y1，x2＝y2。
该第二具体实施例中，新定义的定时器的开始计时的时间点、新定义的定时器定时重新启动的时间点以及新定义的定时器结束的时间点，包括但不限于表1所列的时间点，其中表1中“√”表示允许，“×”表示不允许。
表1
Figure PCTCN2016077672-appb-000001
Figure PCTCN2016077672-appb-000002
该第二具体实施例中，在图1所示的定时器的基础上，引入新的定时器，并该新的定时器设置对应的门限，根据新的定时器对应的门限，得到多个时长区间，不同的时长区间对应不同长度的DPCCH前导码，从而可以实现在UE长时间关闭发射机后启动上行传输时，发射较长的DPCCH前导码，使得网络侧有足够的DPCCH前导码进行上行同步，并且如果UE仅是短时间关闭发射机后启动上行传输，依然可以采用较短的DPCCH前导码。
第三具体实施例
在第一具体实施例和第二具体实施例的基础上，引入UE与基站约定上行信号发射的起始位置的方法。当UE需要发射数据信道或者控制信道时，只能在预设的时间位置处开始发射。预设的时间位置可以是网络通知给UE的，也可以是网络侧与UE预先约定的。基站能够预先获知DPCCH的发射的起始位置，提高了上行同步的准确性。
如图6所示，实线为帧边界，虚线为预定义的作为上行信号发射的起始位置，即预设的时间位置，图6所示的起始位置是相对于帧边界定义的，实施中，起始位置还可以相对于TTI边界、下行无线帧的边界等定义。例如，UE发射控制信道，则UE从图6虚线所示的起始位置处开始发射，不能从虚线之外的位置发射控制信道。
该具体实施例中还可以针对不同的信道，定义不同的起始位置，例如，UE如果发射数据信道，则起始位置为实线所示的帧边界。
具体地，如果UE需要发射DPCCH，其中包括DPCCH前导码，必须从与DPCCH对应的起始位置处开始发射。如果UE需要发射E-DCH数据信道，其中包括增强专用物理数据信道(Enhanced Dedicated Physical Data Channel，E-DPDCH)和E-DPCCH，则必须从E-DCH数据信道对应的起始位置处开始发射。
该具体实施例中，起始位置的定义可以是在现有的定时边界的基础上增加时间偏置得到。其中，现有的定时边界包括但不限于：下行无线帧边界、上行无线帧边界、上行E-DCH数据的TTI边界等。时间偏置可以是以时隙、TTI、帧、毫秒等为单位。其中，定时边界可以是周期性出现。
该具体实施例中，可以针对每个上行信道分别定义不同的起始位置，例如，DPCCH的起始位置可以比E-DCH的起始位置提前x个时隙。这样，UE在发送E-DCH之前，会多发送x个时隙的DPCCH前导码，有利于基站获得上行同步。
结合第一具体实施例和第二具体实施例，可以针对不同长度的DPCCH前导码，指定不同的DPCCH的起始位置。具体地。当UE根据第一具体实施例或第二具体实施例确定需要使用第一长度的DPCCH前导码时，DPCCH的起始位置为起始位置一；当UE根据第一具体实施例或第二具体实施例确定需要使用第二长度的DPCCH前导码时，DPCCH的起始位置为起始位置二。
具体地，网络侧可以通过RRC信通知UE起始位置的定义、起始位置与信道之间的对应关系、起始位置与DPCCH前导码的长度之间的对应关系。其中，起始位置的定义具体可以为相对于的定时边界以及相对该定时边界的偏置量。或者，网络侧可以通过物理层信令，例如HS-SCCH命令通知UE始位置的定义、起始位置与信道之间的对应关系、起始位置与DPCCH前导码的长度之间的对应关系。或者，网络侧与UE通过预先定义的方式相互约定起始位置的定义、起始位置与信道之间的对应关系、起始位置与DPCCH前导码的长度之间的对应关系。
