- 5G New Radio is a newly proposed topic in the 3GPP organization, located in release 14.
- the LTE standard proposed by the 3GPP organization has been widely used worldwide, and is called 4G communication technology.
- 4G communication technology For example, China Mobile, China Unicom and China Telecom have adopted 4G LTE TDD and FDD mode transmission technologies respectively, and provided high-speed and convenient mobile network services for users.
- the 5G NR uses a time slot as a scheduling unit, and a time slot may include 14 symbols, which are specific to each symbol, and may be used for uplink, downlink, idle, unknown resources, or reserved resources, where the use is idle and there is no indication. Symbols of use; the purpose of the "unknown" resource is to support redundant designs made by multiple service types designed to support the type of service or switching between multiple transmissions. Since each symbol has multiple uses, the structure on one slot is composed of a combination of symbols of various types. For example, one slot can be the first 3 symbols as the down symbol, and the last 10 Upstream symbol.
- Several commonly used structures include full uplink (that is, 14 symbols are uplink), full downlink (that is, 14 symbols are downlink), and partial downlink uplink (that is, part of the symbol is downlink and the other part is uplink).
- the base station transmits the slot format to the terminal through high layer signaling (RRC signaling, MAC signaling) or dynamic signaling (Group-common PDCCH).
- RRC signaling RRC signaling, MAC signaling
- MAC signaling MAC signaling
- Group-common PDCCH group-common PDCCH
- the uplink control channel is used to carry uplink control information, such as ACK/NACK, CQI feedback, and the like.
- the uplink control channel includes a short duration uplink control channel and a long duration uplink control channel.
- the short duration uplink control channel may occupy one or two orthogonal frequency division multiplexing (OFDM) symbols in the time domain; the long duration uplink control channel may occupy 4 in the time domain in one time slot. Up to 14 OFDM symbols.
- the long duration uplink control channel may be transmitted on multiple time slots and transmitted on each time slot with the same duration.
- a multi-subframe bearer PUCCH is designed. Specifically, the base station configures the number of slots for PUCCH repeated transmission by using high-layer signaling, and schedules the UE to transmit the PUCCH in the uplink subframe.
- the LTE system can only transmit the PUCCH in the uplink subframe, and the uplink subframe is a subframe in which the symbols in the subframe are all uplink symbols. In this case, the number of symbols carrying the PUCCH in each uplink subframe is the same.
- the symbol position of the bearer PUCCH is fixed, that is, the PUCCH covers the first symbol to the last symbol of each uplink subframe.
- one possible form of extension is to carry a PUCCH at a fixed symbol position of each slot to achieve transmission of a multi-slot PUCCH.
- the description of the subframes in the LTE and the slots in the NR is a time domain scheduling unit. Specifically, the duration of the subframe in the LTE is the same as the duration of the slot in the case of the 15 kHz subcarrier spacing in the NR.
- the introduction of the slot concept in NR is mainly to facilitate the description of the scheduling in the case of multiple subcarrier spacing.
- the prior art adopts a fixed location as a time domain resource of a long PUCCH, but the slot structure in the 5G NR is variable, and it is difficult to carry a long PUCCH in a fixed location in the slot.
- the multi-slot long PUCCH is carried in the fixed 5th to 12th symbols in the slot, it is required that each of the slots carrying the multi-slot long PUCCH is an uplink symbol in the 5th to 12th symbols.
- a time slot only needs to satisfy 8 uplink symbols to carry the long PUCCH.
- there is a clear requirement for the slot format at a fixed location thereby wasting a lot of slots with sufficient upstream symbols, but the upstream symbols are not located at the fixed location.
- the repetition of PUCCH is only repeated in the uplink subframe, and the long PUCCH of NR can be transmitted in multiple slot formats. Therefore, two problems need to be solved: the first question, whether the slot format can bear Long PUCCH needs to be judged.
- This problem only occurs in the TDD system, that is, on the same frequency domain resource, part of the time domain resource is used as the uplink transmission resource, and part of the time domain resource is used as the downlink transmission resource.
- the FDD system one frequency When the domain resource is only used for uplink transmission or downlink transmission, there is no such problem; the second problem is that when there are enough uplink symbols in the slot format, the transmission of the long PUCCH on which symbols also requires further rules to be limited. Otherwise, If the base station indicates that the first few symbols of each slot start transmitting long PUCCH, the overhead is too large.
- the present application provides rules for determining start symbols in a time slot, including determining long PUCCH according to a relative position within an uplink symbol range or a position of an adjacent time slot long PUCCH. Start symbol.
- the solution of the embodiment of the present application provides a method for implementing a multi-slot long PUCCH.
- the first scheme gives a method for determining whether the time slot on the terminal side can support the long PUCCH repetition; the second scheme gives the rule for the terminal to determine which symbols of the time slot transmit the long PUCCH.
- the terminal determines whether the time slot can carry the long PUCCH.
- the terminal In the prior art LTE, the terminal only transmits the long PUCCH in the uplink subframe, so there is no step in which the terminal determines whether a certain subframe can carry the long PUCCH. In the 5G NR, since a time slot can have some uplink symbols and some downlink symbols, the terminal needs to determine whether the time slot can carry long PUCCH repetitions. This step is not available in the prior art.
- Step 1 The terminal receives the indication signaling sent by the base station, and instructs the terminal to send the multi-slot long PUCCH and the parameters of the multiple time slots long PUCCH.
- Step 2 The terminal determines whether the time slot n can carry the long PUCCH. If the terminal can transmit, the terminal transmits the long PUCCH in the time slot. If the terminal cannot transmit, the terminal determines whether the next time slot can carry the long PUCCH.
- Step 2 is specifically implemented by using step 2-1.
- Step 2-1 includes: the terminal determines, according to the slot format and the parameter of the long PUCCH, whether the slot n can carry the long PUCCH.
- the terminal determines, according to the length of the long PUCCH in the time slot and the number of uplink symbols available in the time slot n, if the length of the long PUCCH in the time slot is less than or equal to the number of uplink symbols available in the time slot n, then It is determined that the time slot n can carry the long PUCCH, otherwise the time slot n cannot carry the long PUCCH; optionally, the available uplink symbol number includes the total number of consecutive uplink symbols in the time slot n; optionally, the available uplink The number of symbols is the total number of consecutive uplink symbols in a slot minus x, where x is an uplink symbol for other purposes, such as a symbol occupied by an SRS (sounding reference signal) of LTE when LTE and NR coexist, or the terminal is in the The number of symbols occupied by the SRS in the time slot transmission.
- SRS sounding reference signal
- the terminal determines the function of the symbol position covered by the long PUCCH indicated by the base station. If all the uplink symbols, the time slot can carry the long PUCCH, otherwise the time slot cannot bear the long PUCCH.
- Embodiment 1 The terminal determines whether the time slot can carry the long PUCCH according to the consecutive uplink symbol number.
- the first embodiment is a specific embodiment of the first step 2-1 of the solution, which is based on whether the total number of consecutive uplink symbols is greater than or equal to the number of symbols occupied by the long PUCCH in the time slot.
- the length of the multi-slot long PUCCH on the y time slots is L1, L2, ... Ly; the terminal determines in the nth time slot whether it can carry the i-th long PUCCH repetition of the multi-slot long PUCCH, the ith long
- the PUCCH occupies Li symbols.
- the terminal acquires the slot structure of the nth slot, and obtains the number of consecutive uplink symbols in the slot structure. If the consecutive uplink symbol number is greater than Li, the terminal transmits the ith repetition of the long PUCCH in the time slot, otherwise The terminal continues to determine whether the next time slot can carry the ith repetition of the long PUCCH, and so on. See Figure 15 for details.
- Embodiment 2 In the LTE and NR coexistence scenarios, the terminal determines whether the time slot can carry the long PUCCH according to the number of available uplink symbols.
- the second embodiment is a specific embodiment of the first step 2-1 of the solution, which is based on whether the total number of available uplink symbols is greater than or equal to the number of symbols occupied by the long PUCCH in the time slot.
- LTE and NR can share the same frequency band.
- the NR terminal needs to exclude some symbols occupied by LTE. These symbols may be used for LTE SRS transmission, etc.
- the NR terminal needs to exclude the terminal.
- the number of symbols used for transmission of the uplink symbols in the time slot for example, the terminal may have transmission of a short duration uplink control channel or other signaling transmission.
- the terminal After the symbols are excluded, if the total number of consecutive consecutive uplink symbols is greater than or equal to the number of symbols occupied by the long PUCCH in the time slot, the terminal transmits a repetition of the long PUCCH in the time slot, otherwise the terminal continues to determine whether the next time slot can Carry a repetition of long PUCCH, and so on. For example, see Figure 16.
- Embodiment 3 The terminal determines whether the long PUCCH can be carried in a fixed position of the time slot.
- the third embodiment is a specific embodiment of the first step 2-1 of the solution, which is based on whether the base station allocates the uplink symbol of the long PUCCH to the available uplink symbol.
- the base station sends at least two of the start symbol, the number of symbols, and the end symbol of the long PUCCH by using the signaling, and the terminal determines, on each time slot, whether the symbol positions covered by the long PUCCH are all uplink symbols. For example, the base station notifies the terminal to transmit the long PUCCH in the 5th to 10th symbols of the slot, and the terminal acquires the slot structure of the nth slot, and the 5th to the 10th symbols in the slot structure are all uplink. The symbol, the terminal transmits the repetition of the long PUCCH in the nth time slot, otherwise the terminal continues to determine whether the n+1th time slot satisfies the requirement. For example, see Figure 17.
- Solution 2 The terminal determines the start symbol of the uplink symbol of the long PUCCH in the slot.
- Scheme 1 provides a method for the terminal to determine whether a time slot can carry a long PUCCH repetition. After determining that a time slot has sufficient resources to carry the long PUCCH, the terminal needs to determine to transmit the long PUCCH on those resources of the time slot. It is related to the determination of the long PUCCH start symbol. For example, the repetition of long PUCCH occupies 8 symbols, and one slot has 10 uplink symbols. How to determine which symbols in 10 symbols are used to carry long PUCCH is the problem to be solved in scheme 2.
- each slot needs a start symbol label, indicating that the start symbols of all slots will add a lot of signaling overhead;
- the fixed position as described in the prior art has strict requirements on the format of the time slot.
- the solution of the present application adopts the relative position in the range of the uplink symbol in the time slot as the basis for determining the starting symbol, and is embodied in the standard.
- the terminal determines the location of the long PUCCH according to the relative position within the uplink symbol range, and transmits the long PUCCH.
- the relative position within the upstream symbol contains a number of possibilities.
- the long PUCCH of the time domain length Li i>1, that is, using the following rule from the second time slot of the multi-slot long PUCCH

- one possible implementation is the last symbol in the uplink symbol range and the previous Li-1 symbols as the time domain resource of the long PUCCH;
- the implementation is to transmit the long PUCCH with the symbol of the xth symbol of the uplink symbol range and the subsequent Li-1 symbols, or the symbol of the last xth symbol of the uplink symbol range and the previous Li-1 symbol transmission.
- Long PUCCH Long PUCCH.
- Another possible implementation manner is to separately define two frequency hopping portions of the long PUCCH.
- the start symbol of the first frequency hopping portion is located on the first symbol of the uplink symbol range or the symbol of the xth symbol of the uplink symbol range; the end symbol of the second frequency hopping portion is located at the last symbol of the uplink symbol range or The upper symbol range is on the symbol of the yth symbol of the last.
- Another possible implementation manner is to consider the relative position of the multi-slot long PUCCH, where the end symbol of the long PUCCH in one slot is located in the last symbol of the uplink symbol range, and the start symbol of the long PUCCH in the other time slot thereafter.
- the above is for the description of two time slots.
- one way is to transmit every two time slots according to the above method, and the other way is the long PUCCH in the first time slot of multiple time slots.

其中,存储器103用于存储执行本申请方案的应用程序代码,并由处理器101来控制执行。处理器101用于执行存储器103中存储的应用程序代码,从而实现下文中本申请实施例提供的方法。
在具体实现中,作为一种实施例,处理器101可以包括一个或多个CPU,例如图1中的CPU0和CPU1。
在具体实现中,作为一种实施例,网络设备10可以包括多个处理器,例如图1中的处理器101和处理器108。这些处理器中的每一个可以是一个单核(single-CPU)处理器,也可以是一个多核(multi-CPU)处理器。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。

本申请实施例提供了一种发送和接收信息的方法,如图2所示,该方法包括:
201、终端确定第i个时隙中的m
i个上行符号。
202、基站确定第i个时隙中的m
i个上行符号。
其中,步骤201和步骤202的执行顺序不分先后,即步骤202可以执行在步骤201之后,也可以执行在步骤201之前。
可选的,m
i个上行符号为连续的m
i个上行符号。当然,m
i个上行符号也可以为不连续的上行符号。本申请实施例对此不作具体限定。需要说明的是,i不同时,m

随着5G无线通信技术进入讨论阶段,目前在第三代合作伙伴计划(3rd generation partnership project,简称3GPP)组织中存在两个研究方向,分别为考虑后向兼容的研究方向和不考虑后向兼容的研究方向,其中,不考虑后向兼容的研究方向,被称为5G新空口(new radio,简称NR)。
在5G NR中,PUCCH可以承载上行控制信息,比如肯定回复(acknowledgement,简称ACK)/否定回复(negative acknowledgement,简称NACK)、信道质量指示(channel quality indicator,简称CQI)等。用来承载上行控制信息的PUCCH可以包括短时长(short)PUCCH和长时长PUCCH。短时长PUCCH可以在时域上占用1个或2个正交频分复用(orthogonal frequency division multiplexing,简称OFDM)符号,其中,短时长PUCCH也可以称为第二时长PUCCH,第二时长PUCCH占用的符号数为1或2。长时长PUCCH可以在一个时隙中占用4个到14个OFDM符号。
长时长PUCCH在多个时隙上传输,能够提高长时长PUCCH的覆盖范围,具体的,长时长PUCCH在每个时隙上传输的时长可以相同,也可以不同。
可选的,K个时隙内的第一PUCCH上承载的信息可以相同。
可选的,i可以为大于等于k的整数。具体的,第i个时隙可以为多个时隙中的终端和基站确定的一个时隙。示例性的,基站指示终端在多个时隙上发送第一PUCCH上承载的信息时,终端可以以接收到该信息的时隙为起始时隙依次确定用于传输第一PUCCH上承载的信息的K个时隙。其中,终端确定的用于传输K个时隙中的第k个时隙内的第一PUCCH上承载的信息的时隙即第i个时隙。
本申请实施例提供的方法,终端和基站可以基于预设规则确定用于传输第一PUCCH上承载的信息的上行符号,而不在固定的上行符号上传输第一PUCCH上承载的信息,因此,能够提高传输第一PUCCH上承载的信息的灵活性。一种可实现的方式是基站为终端指示每个时隙中的用于传输第一PUCCH上承载的信息的上行符号中的起始符号,但是,与本申请实施例提供的方法相比,这将增加大量的信令开销。
具体的,在本申请实施例中,终端或基站可以通过以下方式中的任意一种方式确定m
i 个上行符号。
方式一、通过第i个时隙的时隙格式确定m
i个上行符号。
在5G NR中,以时隙作为调度的基本单元,一个时隙可包含14个符号,具体到每个符号上,其可以为上行符号、下行符号、用途为空闲的符号、用途为未知的符号或保留的符号。其中,用途为空闲的符号即为没有指示用途的符号;用途为未知的符号是为了支持多种服务类型而做出的冗余设计的符号,保留的符号是为了支持服务类型或多种传输之间的切换而设计的符号。
一个时隙是由各类用途的符号组合而成的,例如,一个时隙中的符号的用途可以是开头3个符号为下行符号,最后10个符号为上行符号。时隙格式即用于描述时隙中的符号个数以及每个符号的用途。在图3至图13中,“U”表示上行符号,“D”表示下行符号,未标明的符号可以为其他类型的符号。
方式(1)、m
i个上行符号中的第1个上行符号为第i个时隙中的上行符号中的第x
1个上行符号,x
1为大于0的整数。
当x
1等于1,参见图3,m

其中,第二PUCCH可以为短时长PUCCH或与第一PUCCH为不同格式的PUCCH。
方式(2)、m
i个上行符号中的最后一个上行符号为第i个时隙中的上行符号中的倒数第y
1个上行符号,y
1为大于0的整数。
当y
1等于1,参见图5,m

i的值为8为例进行说明。
当y
1大于1,参见图6,m
i个上行符号中的最后一个上行符号为第i个时隙中的上行符号中的倒数第y
1个上行符号。可选的,第i个时隙中的上行符号中的后y
1-1个符号包括但不限于用于发送SRS和/或第二PUCCH的符号。图6中以m
i的值为5,y
1的值为3为例进行说明。
方式二、通过第i-r个时隙确定m
i个上行符号,该情况下,k>2,m
(i-r)个上行符号为第i-r个时隙中的上行符号,m
(i-r)个上行符号用于传输第k-1个时隙内的第一PUCCH上承载的信息,第k-1个时隙为用于传输第一PUCCH上承载的信息的K个时隙中的第k-1个时隙,m
(i-r)为大于0的整数,r为大于0的整数,i-r为大于0的整数。
方式(3)、参见图7,若第i-r个时隙中的m
(i-r)个上行符号中的最后一个上行符号为第i-r个时隙中的上行符号中的最后一个上行符号,m
i个上行符号中的第1个上行符号为第i个时隙中的上行符号中的第1个上行符号。图7中以m
i和m
(i-r)的值均为5为例进行说明。
可选的,m
(i-r)可以为大于3的整数。
方式(3)中的m
(i-r)个上行符号和m

可选的,参见图9,若k等于K,m

该情况下,终端或基站在K个时隙中的除第1个和最后一个时隙之外的每个时隙上都可以采用方式一或方式二中所描述的任意一种方式确定用于传输第一PUCCH上承载的信息的上行符号。当然也可以采用其他方式确定,本申请实施例对此不做具体限定。
其中,上述实施例中第k个时隙内的第一PUCCH可以跳频也可以不跳频。在第k个时隙内的第一PUCCH跳频的情况下,第k个时隙内的第一PUCCH包括第一部分和第二部分,m

该情况下,第一部分可以为第k个时隙内的第一PUCCH的第一跳频部分,第二部分可以为第k个时隙内的第一PUCCH的第二跳频部分,图10-图13也是以此为例进行绘制的。当然,第一部分和第二部分也可以仅仅是第k个时隙内的第一PUCCH的两个部分,而不是第k个时隙内的第一PUCCH的两个跳频部分,本申请实施例对此不作具体限定。
上述实施例是在得知第i个时隙可以传输第一PUCCH上承载的信息时确定第i个时隙中的用于传输第一PUCCH上承载的信息的上行符号的方法。在5G NR中,在每个时隙中的固定的多个符号上传输第一PUCCH上承载的信息时,由于时隙格式多变,要求时隙中固定的多个符号上传输第一PUCCH上承载的信息的难度比较大。例如,如果K个时隙上固定的第5个至第12个符号上传输第一PUCCH上承载的信息,则要求K个时隙中的每个时隙上的第5个至第12个符号均为上行符号,而实际上一个时隙仅需要满足有8个上行符号就可以传输第一PUCCH上承载的信息了。从上述分析可以看出,在每个时隙中的固定的多个符号上传输第一PUCCH上承载的信息对时隙格式有明确的要求,从而浪费了很多有足够的上行符号,但是上行符号不位于固定位置的时隙,从而会使得资源利用不充分。
为此,本申请实施例还提供了一种发送和接收信息的方法,其中包括了确定第i个时隙的方法,参见图14,包括:
1401、基站向终端发送第一PUCCH的至少一个参数。
1402、终端从基站接收第一PUCCH的至少一个参数。
其中,至少一个参数指示用于传输第一PUCCH上承载的信息的时隙的个数K,至少一个参数还指示用于传输第一PUCCH上承载的信息的K个时隙中的第k个时隙内的第一PUCCH所占用的符号数m
k,K为大于1的整数,k为大于1小于等于K的整数,m
k为大于0的整数。
其中,K个时隙中的每个时隙内的第一PUCCH所占用的符号数可以相同也可以不同。
示例性的,若K=3,基站向终端发送的第一PUCCH的至少一个参数可以参见表1。
表1
时隙个数 | 第1个时隙内的符号数 | 第2个时隙内的符号数 | 第3个时隙内的符号数 |
3 | m 1 | m 2 | m 3 |
具体的,若K个时隙中的每个时隙内的第一PUCCH所占用的符号数相同,基站也可以向终端发送时隙个数K和每个时隙内的或K个时隙中的第一个时隙内的第一PUCCH所占用的符号数即可。
1403、终端根据第一PUCCH的至少一个参数在第i个时隙上发送第k个时隙内的第一PUCCH上承载的信息。
第k个时隙为用于传输第一PUCCH的K个时隙中的第k个时隙。
1404、基站根据第一PUCCH的至少一个参数在第i个时隙上接收第k个时隙内的第一PUCCH上承载的信息。
其中,第i个时隙中的上行符号数大于等于m
k。进一步的,第i个时隙中的连续的上行符号数大于等于m
k。
本申请实施例提供的方法,基站和终端可以确定第一PUCCH的至少一个参数,并根据该至少一个参数在第i个时隙上传输第k个时隙内的第一PUCCH上承载的信息。其中,第i个时隙只需要满足第i个时隙中的上行符号数大于等于m
k即可,从而使得终端在任何 满足其中的上行符号数大于等于m
k的条件的时隙上均可以作为K个时隙中的第k个时隙传输第一PUCCH上承载的信息,可以防止资源浪费。
可选的,在步骤1403之前,该方法还可以包括:终端确定K个时隙的时隙格式,K个时隙的时隙格式用于终端确定K个时隙中的每个时隙中的符号个数以及符号类型。
一种可实现的方式,基站可以向终端发送K个时隙的时隙格式,终端从基站接收K个时隙的时隙格式,一种可实现的方式,K个时隙的时隙格式可以为静态配置或半静态配置的,具体的,基站可以通过高层信令,例如,无线资源控制(radio resource control,简称RRC)信令、媒体接入控制(media access control,简称MAC)信令,向终端发送K个时隙的时隙格式。另一种可实现的方式,基站可以通过动态信令,例如,组内相同的物理下行控制信道(Group-common physical downlink control channel,简称Group-common PDCCH),向终端发送K个时隙的时隙格式。
该情况下,终端可以根据K个时隙的时隙格式确定K个时隙中的每个时隙内的上行符号的个数或连续的上行符号的个数。
可选的,步骤1403在具体实现时可以包括:终端根据第一PUCCH的至少一个参数确定第i个时隙,并在第i个时隙上发送第k个时隙内的第一PUCCH上承载的信息。相应的,步骤1404在具体实现时可以包括:基站根据第一PUCCH的至少一个参数确定第i个时隙,并在第i个时隙上接收第k个时隙内的第一PUCCH上承载的信息。
具体的,终端在确定第i-r个时隙之后,若确定第i-r个时隙之后的某个时隙中的上行符号数或连续的上行符号数大于等于m
k,则可以确定该时隙为第i个时隙。第i-r个时隙用于传输K个时隙中的第k-1个时隙内的第一PUCCH上承载的信息。
在LTE系统中,终端只在上行子帧传输长时长PUCCH上承载的信息,所以不存在终端判断某个子帧是否能够传输长时长PUCCH上承载的信息这个步骤。而在5G NR中,由于一个时隙既可以有部分上行符号也可以有部分下行符号,终端需要判断该时隙是否能够传输长时长PUCCH上承载的信息,这个步骤是现有技术中没有的。
可选的,第i个时隙中的上行符号中的除x
4个上行符号之外的上行符号数大于或等于m
k,x
4为大于0的整数。
可选的,x
4个上行符号可以包括但不限于第i个时隙中的上行符号中的用于传输SRS和/或第二格式PUCCH的上行符号。
该情况下,终端在确定第i-r个时隙之后,若确定第i-r个时隙之后的某个时隙中的除x
4个上行符号之外的上行符号数大于或等于m
k,则可以确定该时隙为第i个时隙。
可选的,至少一个参数还指示K个时隙中的第1个时隙内的第一PUCCH的起始符号编号和符号个数L,第i个时隙中的与第1个时隙内的第一PUCCH的起始符号编号相同的符号为上行符号,第i个时隙中的与第1个时隙内的第一PUCCH起始符号编号相同的符号之后有L-1个符号为上行符号,L为大于1的整数。
其中,L具体可以为大于3的整数,即第k个时隙内的第一PUCCH为长时长PUCCH。第i个时隙中的L个符号可以为连续或不连续的L个符号。
该可选的方式中,基站可以通过信令发送第1个时隙内的第一PUCCH的起始符号编号、符号数、结束符号编号其中的至少两项。
本申请实施例提供的上述方法可以应用于时分双工(time division duplexing,简称TDD)系统,也可以应用在频分双工(frequency division duplexing,简称FDD)系统中。
5G NR简介:
5G New Radio(5G NR)是在3GPP组织中新近提出的一个课题,位于release 14中。在过去的近10年中,3GPP组织提出的LTE标准已经被全世界广泛使用,被称作4G通信技术。例如,中国移动、中国联通、中国电信,都分别采用了4G LTE TDD和FDD模式的传输技术,并为广大用户提供了高速便捷的移动网络服务。
而随着新一代5G技术进入讨论阶段,原先4G LTE里已经达到的系统结构和接入流程是否继续采纳?一方面,由于通信系统是后项兼容的,所以后来研发的新技术倾向于兼容之前已经标准化的技术;而另一方面,由于4G LTE已经存在了大量的现有设计,如果为了达到兼容,必然要牺牲掉5G的很多灵活度,从而降低性能。所以,目前在3GPP组织中两个方向并行研究,不考虑后向兼容的技术讨论组,被称为5G NR。
时隙格式:
5G NR以时隙为调度单元,一个时隙可包含14个符号,具体到每个符号上,其用途可以是上行、下行、空闲、未知资源或保留资源,其中,用途为空闲即为没有指示用途的符号;所述用途“未知”资源目的是支持多种服务类型做出的冗余设计,所述用途为保留资源的目的是支持服务类型或者多种传输之间的切换而设计。由于每个符号都有多种用途的可能,一个时隙上的结构是由具有多种各类用途符号的组合而成的,例如一个时隙可以是开头3个符号为下行符号,最后10个上行符号。几种常用的结构包括全上行(即14个符号均为上行)、全下行(即14个符号均为下行)、部分下行部分上行(即部分符号为下行、另一部分为上行)。
基站通过高层信令(RRC信令、MAC信令)或动态信令(Group-common PDCCH)传输时隙格式给终端。
上行控制信道PUCCH:
在5G NR中,上行控制信道用来承载上行控制信息,比如ACK/NACK、CQI反馈等。上行控制信道包括短时长上行控制信道和长时长上行控制信道。短时长上行控制信道可以在时域上占用1个或2个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号;长时长上行控制信道可以在一个时隙内的时域上占用4个到14个OFDM符号。在一些场景下,为了提高覆盖范围,长时长上行控制信道可以在多个时隙上传输,并且在每个时隙上传输的时长相同。
现有技术的技术方案:
现有的LTE系统中存在多子帧承载PUCCH的设计,具体而言,基站通过高层信令配置PUCCH重复传输的时隙个数,并在上行子帧调度UE传输PUCCH。由于LTE系统仅能在上行子帧传输PUCCH,所述的上行子帧是子帧中的符号均为上行符号的子帧,此时,每个上行子帧中承载PUCCH的符号数是相同的,而且所述承载PUCCH的符号位置是固定的,即PUCCH覆盖每个上行子帧的第一个符号至最后一个符号。在目前的讨论中,一种可能的扩展形式是在每个时隙的固定符号位置承载PUCCH以达到多时隙PUCCH的传输。
LTE中子帧和NR中时隙的描述都是一种时域调度单元,具体来讲,LTE中的子帧的时长和NR中15kHz子载波间隔情况下的时隙时长相同。NR中引入时隙概念主要是为了应对多种子载波间隔情况下的调度的描述方便。
现有技术的缺点:
现有技术采用固定的位置作为long PUCCH的时域资源,但是5G NR中时隙结构多变,要求时隙中固定的位置都有资源承载long PUCCH难度比较大。举一个例子,如果多时隙long PUCCH在时隙中固定的第5个至第12个符号承载,则要求每个承载多时隙long PUCCH的时隙在第5个至第12个符号均为上行符号,而实际上一个时隙仅需要满足有8个上行符号就可以承载所述的long PUCCH了。从上述分析可以看出,在固定的位置传输对时隙格式有明确的要求,从而浪费了很多有足够的上行符号,但是所述上行符号不位于所述固定位置的时隙。
在LTE中,PUCCH的重复只在上行子帧中重复传输,而NR的long PUCCH可在多种时隙格式里传输,这样就需要解决两个问题:第一个问题,时隙格式是否能够承载long PUCCH需要判断,这个问题仅出现在TDD系统中,即在同一个频域资源上,一部分时域资源作为上行传输的资源,一部分时域资源作为下行传输的资源,在FDD系统中,一个频域资源仅作上行传输或者下行传输时是不存在这个问题的;第二个问题,时隙格式中有足够的上行符号时,在哪些符号上传输long PUCCH也需要进一步的规则进行限定,否则,如果基站指示每个时隙的第几个符号开始传输long PUCCH,则开销过大。
本申请的实施例给出了TDD情况下多时隙long PUCCH的时隙方法:
1)首先,针对时隙格式是否能够承载long PUCCH的问题,本申请给出了终端侧的判断方法,并给出了多种实施例情况下的方法细节;
2)其次,针对在哪些符号承载long PUCCH,本申请给出了确定时隙内起始符号的规则,包括根据在上行符号范围内的相对位置或者相邻时隙long PUCCH的位置确定long PUCCH的起始符号。
本申请实施例的方案给出了多时隙long PUCCH的实现方法。
其中,方案一给出了终端侧判定时隙是否能支持long PUCCH重复的方法;方案二给出了终端确定在时隙的哪些符号上传输long PUCCH的规则。
在方案一中,终端判断时隙是否能够承载long PUCCH
现有技术LTE中,终端只在上行子帧传输long PUCCH,所以不存在终端判断某个子帧是否能够承载long PUCCH这个步骤。而5G NR中,由于一个时隙即可以有部分上行符号也可以有部分下行符号,终端需要判断该时隙是否能够承载long PUCCH重复,这个步骤是现有技术中没有的。
具体包括以下步骤:
步骤1:终端接收基站发送的指示信令,指示终端发送多时隙long PUCCH,以及多个时隙long PUCCH的参数;
步骤2:终端判断时隙n是否能够承载long PUCCH,如果能承载,则终端在该时隙传输long PUCCH,如果不能承载,终端判断下一个时隙是否能承载long PUCCH;
步骤2在具体实现时具体可以通过步骤2-1实现,步骤2-1包括:终端根据时隙格式和long PUCCH的参数判断该时隙n是否能够承载long PUCCH。
一种可能的实现方式,终端根据long PUCCH在时隙内长度和时隙n中可用的上行符号数判断,如果long PUCCH在时隙内长度小于或等于时隙n中可用的上行符号数,则判定该时隙n可以承载long PUCCH,否则时隙n不能承载long PUCCH;可选的,所述可用的上行符号数包括时隙n内连续的上行符号总数;可选的,所述可用的上行符号数为时隙内连续的上行符号总数减去x,其中x为其他用途的上行符号,例如LTE和NR共存时,LTE的SRS(探 测参考信号)所占用的一个符号,或者该终端在该时隙传输SRS所占用的符号数等。
另一种可能的实现方式,终端判断基站指示的long PUCCH所覆盖的符号位置的功能,如果均为上行符号,则该时隙可以承载long PUCCH,否则该时隙不能承载long PUCCH。
实施例一:终端根据连续的上行符号数判断时隙是否能够承载long PUCCH
实施例一是方案一步骤2-1的一个具体实施例,是以连续的上行符号总数是否大于或等于long PUCCH在时隙内所占的符号数作为判断依据的。
多时隙long PUCCH在y个时隙上的长度分别为L1、L2,…Ly;终端在第n个时隙判断是否能承载多时隙long PUCCH的第i个long PUCCH重复,所述第i个long PUCCH占用Li个符号。终端获取第n个时隙的时隙结构,得到该时隙结构中连续的上行符号数,如果该连续的上行符号数大于Li,则终端在该时隙传输long PUCCH的第i个重复,否则终端继续判断下一个时隙是否能承载long PUCCH的第i个重复,以此类推。具体可参见图15。
实施例二:在LTE和NR共存场景下,终端根据可用的上行符号数判断时隙是否能够承载long PUCCH
实施例二是方案一步骤2-1的一个具体实施例,是以可用的上行符号总数是否大于或等于long PUCCH在时隙内所占的符号数作为判断依据的。
在LTE和NR共存场景中,LTE和NR可共同同一频带,此时,NR的终端需要排除LTE所占用的部分符号,这些符号可能用于LTE SRS传输等;此外,NR终端需要排除该终端在该时隙内上行符号的传输所用的符号数,比如该终端可能有短时长上行控制信道的传输或者其他信令传输。在排除这些符号后,剩余的连续上行符号总数大于或者等于long PUCCH在时隙内所占的符号数时,则终端在该时隙传输long PUCCH的重复,否则终端继续判断下一个时隙是否能承载long PUCCH的重复,以此类推。示例性的,可参见图16。
实施例三:终端判断时隙的固定位置上是否能够承载long PUCCH
实施例三是方案一步骤2-1的一个具体实施例,是以基站分配long PUCCH的固定位置上是否均为可用的上行符号作为判断依据的。
基站通过信令发送long PUCCH的起始符号、符号数、结束符号其中的至少两项,终端在每个时隙上判断所述long PUCCH所涵盖的符号位置上是否均为上行符号。例如,基站通知终端在时隙的第5个至第10个符号传输long PUCCH,终端获取第n个时隙的时隙结构,时隙结构中的第5个至第10个符号如果均为上行符号,则终端在第n个时隙传输long PUCCH的重复,否则终端继续判断第n+1个时隙是否满足要求。示例性的,可参见图17。
方案二:终端判断时隙中的传输long PUCCH的上行符号的起始符号
方案一给出了终端判断一个时隙是否能够承载long PUCCH重复的方法,在确定一个时隙有足够的资源承载long PUCCH后,终端需要确定在所述时隙的那些资源上传输long PUCCH,这就涉及到long PUCCH起始符号的确定。举个例子,long PUCCH的重复占用8个符号,而一个时隙有10个上行符号,如何确定10个符号里哪些符号用于承载long PUCCH是方案二要解决的问题。
需要说明的是,如果最终实现的标准规定或基站通知各时隙在相同的位置承载long PUCCH,则不存在确定起始符号的问题。
在多时隙long PUCCH的配置信令里,由于时隙的数量可多变,而每个时隙都需要一个起始符号标号,分别指示所有时隙的起始符号将增加很多的信令开销;而像现有技术所述的固定位置则对时隙的格式有严格要求。
本申请方案采用时隙中上行符号范围内的相对位置作为起始符号的确定依据,并在标准中进行体现。当传输多时隙long PUCCH时,终端根据上行符号范围内的相对位置确定long PUCCH的位置,并传输long PUCCH。
所述上行符号内的相对位置包含多种可能性。对于时域长度Li的long PUCCH(i>1,即从多时隙long PUCCH的第二个时隙开始使用下述规则),一种可能的实施方式是在上行符号范围内的第一个符号及之后的Li-1个符号作为long PUCCH的时域资源;一种可能的实施方式是在上行符号范围内的最后一个符号及之前的Li-1个符号作为long PUCCH的时域资源;一种可能的实施方式是在与上行符号范围的第x个符号的符号及之后的Li-1个符号传输long PUCCH,或者与上行符号范围的倒数第x个符号的符号及之前的Li-1个符号传输long PUCCH。
另一种可能的实施方式是对long PUCCH的两个跳频部分分别进行限定。第一跳频部分的起始符号位于上行符号范围的第一个符号或者与上行符号范围第x个符号的符号上;第二个跳频部分的结束符号位于上行符号范围的最后一个符号或者与上行符号范围倒数第y个符号的符号上。上述这种方式相对复杂,后续具体实施例没有继续详细描写。
另一种可能的实施方式是考虑多时隙long PUCCH的相对位置,其中,一个时隙内long PUCCH的结束符号位于上行符号范围的最后一个符号,之后的另一个时隙内long PUCCH的起始符号位于上行符号范围的第一个符号。这样两个long PUCCH时域上间隔较小,优点是前一个时隙的long PUCCH内的信道测量结果可以辅助下一个时隙long PUCCH的信道测量,从而提高性能。上述针对的是两个时隙的描述,对于大于2个时隙的情况,一种方式是每两个时隙按照上述方法传输,另一种方式是多时隙的第一个时隙内long PUCCH的结束符号位于上行符号范围的最后一个符号,且多时隙的最后一个时隙内long PUCCH的起始符号位于上行符号范围的第一个符号。
实施例四:终端在第二个时隙及以后的时隙内确定第一个上行符号为传输long PUCCH的上行符号的起始符号
该情况下,可以在5G标准中规定多时隙long PUCCH的第二个时隙及以后的时隙内,各时隙内第一个上行符号作为long PUCCH的资源。
如下图18所示,终端传输多时隙long PUCCH,时隙n作为多时隙long PUCCH的第二个时隙,其中,long PUCCH的起始符号为时隙n的上行符号范围内的第一个符号;时隙n+1作为多时隙long PUCCH的第三个时隙,其中,long PUCCH的起始符号为时隙n+1的上行符号范围内的第一个符号;时隙n+2作为多时隙long PUCCH的第四个时隙,其中,long PUCCH的起始符号为时隙n+2的上行符号范围内的第一个符号。
实施例五:终端在第二个时隙及以后的时隙内确定最后一个上行符号为传输long PUCCH的上行符号的起始符号
该情况下,可以在5G标准中规定多时隙long PUCCH的第二个时隙及以后的时隙内,各时隙内最后一个上行符号作为long PUCCH的资源。
如下图19所示,终端传输多时隙long PUCCH,时隙n作为多时隙long PUCCH的第二个时隙,其中,long PUCCH的结束符号为时隙n的上行符号范围内的最后一个符号;时隙n+1作为多时隙long PUCCH的第三个时隙,其中,long PUCCH的结束符号为时隙n+1的上行符号范围内的最后一个符号;时隙n+2作为多时隙long PUCCH的第四个时隙,其中,long PUCCH的结束符号为时隙n+2的上行符号范围内的最后一个符号。
实施例六:终端在第二个时隙及以后的时隙内确定第x个或倒数第x个上行符号为传输long PUCCH的上行符号的起始符号
该情况下,可以在5G标准中规定多时隙long PUCCH的第二个时隙及以后的时隙内,各时隙内第x个符号作为long PUCCH的起始符号,或各时隙内倒数第x个符号的符号作为long PUCCH的结束符号,x为大于1的整数。
如下图20所示,终端传输多时隙long PUCCH,时隙n作为多时隙long PUCCH的第二个时隙,其中,long PUCCH的起始符号为时隙n的上行符号范围内的第x个符号;时隙n+1作为多时隙long PUCCH的第三个时隙,其中,long PUCCH的起始符号为时隙n+1的上行符号范围内的第x个符号;时隙n+2作为多时隙long PUCCH的第四个时隙,其中,long PUCCH的起始符号为时隙n+2的上行符号范围内的第x个符号。
实施例七:终端根据一个时隙的相邻的时隙上的传输long PUCCH的上行符号确定该时隙上的传输long PUCCH的上行符号的起始符号
如图21所示,在两个时隙的情况下,第一个时隙内的long PUCCH的结束符号为该时隙内上行符号的最后一个符号,第二个时隙的long PUCCH的开始符号为该时隙内上行符号的第一个符号。
一种可能的实现方式,在N个时隙的情况下,N为大于2的整数,每两个时隙依次采用图21所示的方式。示例性的,可参见图21。其中,由于两个longPUCCH接近,两个longPUCCH可共享部分DMRS检测结果以提高性能。
另一种可能的实现方式,在N个时隙long PUCCH中,第二个时隙内的long PUCCH的结束符号为该时隙内上行符号的最后一个符号,第N个时隙的long PUCCH的开始符号为该时隙内上行符号的第一个符号。
本申请实施例提出的方式给出了多时隙长时长上行控制信道的资源分配方法,涉及到时隙是否有资源承载长时长上行控制信道以及所述长时长上行控制信道位于时隙的哪些时域资源上。
