[0026] 具体实施方式 [0026] DETAILED DESCRIPTION

[0027] 本发明的基本构思是:将BITMAP序列设置成可变长度的,通过BITMAP序列有效位的比特个数或者BITMAP长度来确定BITMAP序列。 [0027] The basic idea of ​​the invention is: the BITMAP set to variable length sequence, a sequence determined by the BITMAP BITMAP significant bit sequences or number of bits in length BITMAP. 说明如下: described as follows:

[0028] 基站在控制消息中携带用于指示BITMAP序列有效位个数的字段A以及BITMAP序列,将需要调整工作方式的终端在BITMAP序列中的对应位设置为有效;终端接收到控制消息后,通过统计控制消息字段A后续有效位的个数获得所述BITMAP序列,通过BITMAP序列中相应比特位是否有效确定自己是否需要调整工作方式。 [0028] In the base station control message carries the sequence field for indicating BITMAP BITMAP A sequence and number of effective bits, the terminal will need to adjust the mode of operation in the corresponding bit sequence BITMAP set to be valid; terminal receives the control message, number of statistical control message field a subsequent significant bit sequence to obtain the BITMAP, the corresponding bit in the bit sequence by BITMAP is valid to determine whether they need adjustment mode. [0029] 基站在控制消息中携带用于确定BITMAP序列长度的字段B以及BITMAP序列,将需要调整工作方式的终端在BITMAP序列中的对应位设置为有效;终端接收到控制消息后, 根据所述字段B获得所述BITMAP序列,通过BITMAP序列中相应比特位是否有效确定自己是否需要调整工作方式。 [0029] The base station control message carried in the sequence for determining the length of the BITMAP BITMAP field and sequence B, the terminal will need to adjust the mode of operation in the corresponding bit sequence BITMAP set to be valid; After receiving the control message, according to the BITMAP field B of the sequence obtained by BITMAP sequence corresponding valid bit to determine whether they need adjustment mode.

[0030] 对于没有在BITMAP序列中找到自己位置的终端,基站可以与其约定所有该些终端的处理方式,或者通过信息域中其他字段进行指示,如终端标识字段或调整方式指示比特。 [0030] For the terminal does not find its own position in the BITMAP sequence, the base station may process all the way to its convention the plurality of terminal or field information is indicated by other domains, such as the terminal identification field or bits indicating the adjustment mode.

[0031] 如图1所示,当基站向终端传输消息时,假设系统已将终端分配到不同的组中,每组通过一个组号来标识,同时组中的终端知道自己在组中的相对位置,具体步骤如下: [0031] As shown in FIG. 1, the base station when the message is transmitted to the terminal, the terminal is assumed that the system has been assigned to different groups, each identified by a group number, while the terminals in the group in the group know the relative position, the following steps:

[0032] 步骤101,基站通过下行信道向组中的终端发送基于组的控制消息,该控制消息至少包含一个用于指示组中的哪个或者哪些终端需要根据该消息调整自己后续工作方式的信息域; [0032] Step 101, the base station transmits based on a control group of messages via a downlink channel to the terminals in the group, the control message comprising at least one for indicating the group to which or in which the terminal to adjust the information field their subsequent work based on the message ;

[0033] 对于信息域的表现形式,基站与终端可事先协商确定一种表现形式,或者通过基于组的控制消息的其它字段来确定几种表现形式中的一种。 [0033] For the manifestation information field, the base station and the terminal may be determined prior consultations a form, or one of several forms determined by the other fields in the group based on the control message. 当通过控制消息的其他字段来确定时,该字段可以位于信息域之前,如果有四种信息域表现方式,该字段就需要占用两个比特以指示其中的一种表现形式。 Before when determined by the other fields of the control message, the domain information may be located in the field, if there are four expressions information field, the field will need to take two bits to indicate which of a form.

[0034] 步骤102,组中各终端接收到基于组的控制消息后决定是否需要调整后续工作方式。 [0034] Step 102, the terminal group of each group after receiving a control message based on the decision to modify the subsequent work.

[0035] 基站通过上述节约开销的方法指定某个或者某些终端进行工作方式的调整,终端可以根据控制消息中的其他字段获知进行调整的内容,比如终端可以根据控制消息的消息号判断该消息是要求组中部分终端退出组。 [0035] The above-described method is specified by the base station of a save costs or some adjustment mode terminal, the terminal may be informed of the contents of the other fields adjusted according to the control message, such as the terminal may determine whether the message according to the message number of control messages group is required to exit the terminal portion group.

[0036] 所述调整工作方式是指以下情况之一:基站为一个或多个终端分配上行资源,基站为一个或多个终端分配下行资源,基站命令组中一个或多个终端切换到另一个组,基站命令组中的一个或多个终端退出组。 [0036] the adjustment mode of operation is one of the following means: one or more terminals to a base station uplink resource allocation, a base station for one or more downlink resource assigned to the terminal, the base station commands a group of one or more terminal switches to another group, base station commands the group of one or more terminal exits the group.

[0037] 上述信息域至少包括用于确定BITMAP序列长度的字段和BITMAP序列。 [0037] The information field includes at least means for determining the sequence BITMAP BITMAP field and sequence length. 所述用于确定BITMAP序列的字段可以是用于指示BITMAP序列有效位个数的字段A (如终端个数字段),或者是用于确定BITMAP序列长度的字段B (如BITMAP序列长度字段)。 Means for determining the sequence BITMAP field may be used to indicate the number of significant digits BITMAP field sequence A (terminal number of fields), or for determining the field B (such as the sequence length fields BITMAP) BITMAP sequence length.

[0038] 此外信息域还可以包括以下信息中的一种或几种:统计标识、全体终端工作标识、 调整方式指示比特。 [0038] Further information domain may further include one or more of the following information: identification statistics, all terminal identification work, adjustment mode indication bit. 其中: among them:

[0039] 统计标识是对字段A含义的进一步描述,用于表示所述字段A表示的是组中有多少个终端需要或者不需要根据该控制消息调整后续工作方式,同时用于指示未在BITMAP 序列中指示的终端是否需要调整工作方式。 [0039] Statistics for the field ID is A further description of the meaning of the fields for representing the group A is represented by how many terminals or may not require adjustments to the control message in accordance with the follow-up mode, at the same time is not used to indicate the BITMAP indicating whether the terminal sequence of work needs to be adjusted. 如果统计标识表示字段A表示的是组中的哪个或哪些终端需要根据该控制消息调整后续工作方式,则未在BITMAP序列中指示的终端不需要根据该控制消息调整工作方式;如果统计标识表示字段A表示的是组中的哪个或哪些终端不需要根据该控制消息调整后续工作方式,则未在BITMAP序列中指示的终端需要根据该控制消息调整工作方式。 A field indicating if the statistical identification is a terminal group represented by which of the terminal based on the control message needs to adjust the follow-up mode, not indicated in the BITMAP sequence based on the control message does not require adjustment mode; if the statistical identification field indicating a is a terminal group represented by which of the terminal based on the control message does not require subsequent adjustment work, it is not indicated in the sequence BITMAP requires adjustment based on the control message mode. 具体的说,统计标识是告诉终端按照后续比特中'0'的个数确定BITMAP序列长度,还是按照'1'的个数确定比特码片序列长度,以及BITMAP比特为'0' 以及为'1'时终端的处理。 Specifically, statistics tell the terminal identity is determined according to the number of subsequent bits of '0' BITMAP sequence length, chip or determined bit sequence length, and BITMAP bit is' 0 'according to the number' 1 'and to' processing terminal 1 '.

[0040] 全体终端工作标识通常位于消息域的最前端,用于指示全体终端是否需要调整工 [0040] all the terminal is operating normally at the forefront of message identification fields, for indicating whether all the terminal station needs to be adjusted

9作方式,当全体终端都需要调整工作方式时,通过引入该字段,可以不携带后续BITMAP序列字段等内容,从而节省传输开销; 9 for the embodiment, all terminals are required when the adjustment mode, by introducing this field, may not carry other content subsequent BITMAP field sequence, thereby saving transport overhead;
