- the short-term PUCCH, PUSCH, and other PUCCH transmission modes carrying the SR are as follows:
- the short-length PUCCH carrying the SR and the PUSCH capable of carrying a part of the uplink control information cannot be simultaneously transmitted.
- the long-length control channel carrying the SR collides with the PUSCH, since the two channels occupy the same time domain resource, if the terminal capability supports, simultaneous transmission can be realized by allocating power on the same time domain resource.
- the transmission power of the long-length PUCCH on each symbol is configured as P1
- the transmission power of the PUSCH on each symbol is configured as P-P1.
- the short-length PUCCH carrying the SR occupies only a part of the symbols, since the number of symbols occupied by the short-length PUCCH carrying only the SR can be flexibly changed, it is difficult to give an associated power allocation scheme.
- the scheduling request there is only one configuration of the scheduling request. Since the LTE system supports only one service type, the service type only corresponds to the resource configuration of one scheduling request. Different from LTE, in a 5G system, a terminal can carry multiple service types. Therefore, in the current standard discussion, the NR can be configured with multiple service types, which can be carried by a long-length PUCCH or a short-time PUCCH, or Other bearers. Since these service types are different, the resources of the SR are also independently configured. Therefore, the scheduling request of one service may coincide with the time domain resources of other uplink channels, that is, there are both SR transmission requirements and other uplinks on one symbol. The transmission requirements of the channel.
- the period of the SR can be configured to be 1 symbol, that is, it is possible to transmit the SR on each symbol.
- how the terminal handles the scheduling request and the collision of other upstream channels is a problem to be solved by the present invention.
- an existing PUCCH transmission mode scheduling method is shown in FIG.
- the 0.5ms transmission is divided into two segments in the time domain, and the transmitted position is located on both sides of the entire frequency band to improve the effect of the hierarchical gain.
- 1 ms contains 14 symbols, the first 7 symbols are transmitted on one side of the frequency band, and the last 7 symbols are transmitted on the other side of the frequency band.
- a terminal-initiated SR generally has two forms, for two cases.
- the terminal has resources for periodic scheduling requests allocated by the base station.
- the terminal may send a scheduling request on a fixed time domain, frequency domain, and code domain resource in each cycle.
- the terminal carries an uplink scheduling request when replying to the PUCCH.
- the terminal may jointly encode the information of the uplink scheduling request and other information, and then send the information to the base station.
- the PUCCH carrying the scheduling request can be transmitted simultaneously with the PUSCH, and this involves the problem of power allocation between the two.
- a short-term PUCCH occurs in the 5G NR. Unlike the LTE, the short-term PUCCH may appear only on a part of the symbols, and the remaining symbols do not appear, so the power on different symbols of the PUSCH may change. The allocation plan is no longer applicable.
- the PUSCH may feed back part of the uplink control information, including channel quality information or ACK/NACK information of the previous downlink transmission.
- the scheduling request period may be short and may occur on each symbol. Therefore, the original method is no longer applicable for how to carry a scheduling request with a short period and an indeterminate position on the PUSCH. Further discussion, since only one type of service appears in LTE, corresponding to a scheduling request, the PUSCH is transmitted in the service type, so there is no need to provide a bearer scheduling request on the PUSCH.
- the scheduling request can be jointly encoded with other uplink information and transmitted to the base station through the PUCCH.
- the scheduling request period may be short, the delay requirement is relatively high, and the position is uncertain, it is impossible to jointly encode with other uplink information in advance.
- the existing method in LTE cannot solve the problem that the short-cycle PUCCH encountered by the present invention collides with other channels.
- the 5G NR can use the short-length PUCCH, that is, the PUSCH and the PUCCH are only present in some symbols, and the other symbols still only have the PUSCH, which is not conducive to detecting the PUSCH, and the original power allocation mode is no longer applicable;
- the PUSCH bearer scheduling request is not involved in the original LTE because only one service is supported, and the 5G NR is configured with multiple service types and its period is flexibly configured. Therefore, the scheduling of another service is performed in the PUSCH of one service.
- the request may also appear in any symbol, which is not considered in LTE; for the PUCCH bearer scheduling request and other UCI and joint coding, the joint coding scheme in LTE needs to acquire the scheduling request in advance to encode, A scheduling request with a low latency cannot be supported and cannot meet the requirements.
- the present invention is to solve the problem that only the PUCCH carrying the scheduling request and the other uplink channels collide on the same time domain resource, the PUCCH carrying only the scheduling request is a short-time-length PUCCH, and the other uplink channels include a PUSCH and a PUCCH, wherein the PUCCH is further Further, the method includes a long-length PUCCH, a short-length PUCCH of one symbol, and a short-term PUCCH of two symbols.
- the two cases are discussed.
- the first one is the problem that two channels are simultaneously transmitted and the power is allocated, and the second is two.
- the channel transmits only one type of channel, that is, only transmits the PUSCH and carries the scheduling request information in the PUSCH.
- the short-term PUCCH carrying only the scheduling request and some other time-domain resources of the PUCCH overlap the same is also discussed in two cases.
- the first is that two channels are simultaneously transmitted and power allocated, and the second is to transmit only one channel, and according to some conditions, it is determined whether only the PUCCH carrying only the scheduling request or only the other uplink channel is transmitted.
- the present invention provides a method for transmitting a short-length PUCCH and a PUSCH jointly carrying a scheduling request, and involves simultaneous transmission of 1 to 2 DMRS symbols starting from the PUSCH and simultaneous transmission of symbols of the remaining bearer data, and Given the limits that can be transmitted simultaneously in those cases;
- the present invention gives a PUSCH bearer scheduling request mode, and gives a method that can transmit in any symbol and gives a method for improving the reliability of the scheduling request by using frequency diversity.
- the present invention provides a method of how to allocate power and what only one channel is transmitted under the condition that only the short-length PUCCH carrying the scheduling request collides with other PUCCHs.
- the first processing solution provided by the present application is as follows:
- the first processing scheme is a processing manner in which only a short duration PUCCH carrying a scheduling request is transmitted together with a PUSCH.
- the terminal transmits the PUSCH, it is necessary to simultaneously transmit the scheduling request, and the short-length PUCCH only carries the scheduling request.
- the terminal needs to allocate based on the configured power priority, preferentially allocate a part of power to one channel, and the remaining power is allocated to another channel for transmission.
- the scheme for specifically allocating power should consider whether the DMRS symbol conflicts with the symbol carrying the SR or the symbol of the bearer data following the DMRS symbol.
- the power is preferentially allocated to the short-term PUCCH of the scheduling request, and the remaining power is allocated to the DMRS.
- the terminal can increase the transmission power of the data, and the transmission power of the data is increased in proportion to the transmission power of the DMRS.
- the power increase amount can be identified, or the base station side can obtain the power increase amount by comparing the difference in power between the PT-RS and the DMRS on the same frequency domain resource.
- the terminal can increase the transmission power of the data, and the transmission power of the data is increased relative to the transmission power of the DMRS.
- the base station side can either identify the power increase, or the base station side can compare the PT-RS and the DMRS in the same The difference in power on the frequency domain resources to obtain an increase in power.
- the PUSCH contains two DMRS symbols, and the scheduling request occurs in the second DMRS symbol, as shown in FIG. 11, a part of the power is allocated to the DMRS to ensure that the power of the second DMRS and the first DMRS are the same, and the remaining power allocation is performed.
- One way to carry the symbols of the data later is to maintain the same transmission power as the DMRS portion. Since two DMRS symbols are used for channel measurement of multiple ports, if the powers on the two DMRS symbols are different, interference between multiple ports is caused.
- the terminal can improve the transmission power of the data, and the transmission power of the data is transmitted relative to the DMRS.
- the base station side can either identify the amount of power increase, or the base station side can obtain the power boost by comparing the difference in power between the PT-RS and the DMRS on the same frequency domain resource.
- the power is preferentially allocated to the short-term PUCCH carrying the scheduling request, and the remaining power is allocated to the PUSCH.
- the power can be identified, or the base station side can obtain the power of the PUSCH part on the symbol by comparing the power on the frequency domain resource carrying the PT-RS on different symbols before and after; if the PUSCH has no PT- RS, power is preferentially allocated to the PUSCH, and the remaining power is allocated to the short-term PUCCH carrying the scheduling request. If the power of the partial symbol of the PUSCH decreases, if the base station does not know the power-down value, it may cause a decoding error.
- the power is preferentially allocated to the short-term PUCCH of the scheduling request, and the remaining power is allocated to the DMRS part.

在长期演进(Long Term Evolution,LTE)中,如用户设备(user equipment,UE)有上行传输需求时,UE通过向eNodeB发送调度请求(Scheduling Request,SR)来通知eNodeB有上行数据需要传输。当基站收到UE的SR,基站在合适的时间向UE发送下行控制信令,将分配给UE进行上行传输的资源通知给UE。在LTE中,SR的发送方式有两种,一种是在基站分配的周期性的SR资源上传输,一种是当UE向基站反馈其他上行控制信息时,把SR和其他上行控制信息联合编码后进行传输。
在LTE中,物理层上行控制信道(physical uplink control channel,PUCCH)为长时长的PUCCH,SR的周期较长时,SR可以单独承载在长时长的PUCCH中,也可以将SR和其他上行控制信息联合编码后承载在长时长的PUCCH中。其中,长时长的PUCCH所占的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号数为连续4到14个,采用跳频的方式传输。
在5G中,当SR的周期较短时,将SR与其他上行控制信息进行联合编码后通过长时长的PUCCH传输,不能支持时延较低的SR的传输需求。因此5G中出现了短时长的PUCCH,可以将SR承载在短时长的PUCCH中,或者将短SR和其他上行控制信息联合编码后承载在短时长的PUCCH中。其中,短时长的PUCCH所占的OFDM符号数为1到2个,采用频分复用的方式传输。
但是,当SR的周期可以灵活配置时,单独承载SR的短时长的PUCCH会在任何符号出现,这样会与其他的上行信道在同一时域资源上冲突,即一个符号上既有SR的传输需求也有其他的上行信道的传输需求。此时,针对冲突时间长度内的信号传输问题,现有技术中还没给出具体解决方案。

以下,对本申请中的部分用语进行解释说明,以便与本领域技术人员理解。
本申请中的时域资源是指在时域上分布的一个或多个连续的符号。
本申请中的频域资源是指在频域上分布的一个或多个子载波,本申请中的频域资源单元为子载波。
本申请中的资源单元(resource element,RE)是指时域上1个符号,频域上1个子载波所限定的资源。
本申请中所说的符号,包含但不限于正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号、稀疏码分多址技术(Sparse Code Multiplexing Access,SCMA)符号、过滤正交频分复用(Filtered Orthogonal Frequency Division Multiplexing,F-OFDM)符号、非正交多址接入(Non-Orthogonal Multiple Access,NOMA)符号,具体可以根据实际情况确定,在此不再赘述。
本申请中的PUCCH,为承载终端发给基站的控制信令使用的信道,其中包含了与控制有关的信息,比如回复应答或否定应答(acknowledge/negative acknowledge,ACK/NACK),或者传输上行的信道状态信息(channel state information,CSI),或者承载调度请求等。物理层上行控制信道分为两类,一类为长时长的PUCCH,所占OFDM符号数为连续4到14个,采用跳频的方式传输,解调参考信号(demodulated reference signal,DMRS)和上行控制信息(uplink control information,UCI)分别由不同的符号承载,在每个跳频部分上可采用正交覆盖码扩频以增加容量;另一类为短时长的PUCCH,所占OFDM符号数为1到2个,在频域物理资源块(Physical resource block,PRB)上,可以用序列承载信息,也可以有DMRS和上行控制信息(uplink control information,UCI)分别占用不同的子载波,进行频分的方式传输。在一个时隙上,PUCCH可能位于任何位置传输。
本申请中的SR,是终端在有上行传输需求时,向基站发送的请求信令,以获得基站分配的时频域资源。基站给终端配置传输SR的资源,该资源周期性重复。当基站收到终端的SR,基站在合适的时间发送下行控制信令,承载分配的资源信息给终端,之后,终端在基站分配的资源上进行上行传输。在LTE中,调度请求有两种承载方式,一种是在所述基站分配的周期性资源上由终端传输,一种是当终端反馈其他上行控制信息时,把SR通过和其他上行控制信息联合编码进行传输。
本申请中的物理层上行共享信道(Physical uplink shared channel,PUSCH),是终端上传输数据以及部分控制信息的信道。在新通信协议(New radio,NR)中,PUSCH目前同意的结构如图2,在PUSCH的起始1~2个符号承载DMRS,用于支持多个端口的信道测量。在PUSCH其余符号上承载数据或其他控制信息,在所述的其他符号上,有一固定的频域资源承载相位跟踪参考信号(phase tracking reference signal,PT-RS),在该符号上 终端传输相同的信号用于检测相位噪声。所述PT-RS在PUSCH是否存在是提前配置的。
为了解决冲突的时域资源上的信号传输问题,本申请提供一种上行传输方法,主要包括以下步骤:
步骤101,终端获取第一传输功率和第二传输功率。
其中,第一传输功率和第二传输功率分别是终端为第一上行信道和第二上行信道分配的在第一时域资源上传输的功率。第一传输功率与第二传输功率之和等于终端在第一时域资源上的总传输功率。
其中,第一上行信道是仅承载SR的PUCCH。第二信道可以是长时长的PUCCH,也可以是短时长的PUCCH,还可以是PUSCH,但是第二上行信道为短时长的PUCCH时,短时长的PUCCH不包括仅承载SR的短时长的PUCCH。
其中,第一上行信道占用第一时域资源传输SR。
可选的,第一时域资源的长度为1符号长度或2符号长度,1符号长度为1个符号占用的时间长度,2符号长度为2个连续的符号占用的时间长度。可选的,第一上行信道为短时长的PUCCH,例如,第一上行信道为1符号长度的PUCCH,或者2符号长度的PUCCH。
其中,第一时域资源与第二上行信道占用的部分时域资源或全部时域资源相同,换言之,第一时域资源包含在第二上行信道占用的时域资源中。
步骤102,终端采用第一传输功率在第一时域资源上传输第一上行信道,终端采用第二传输功率在第一时域资源上传输第二上行信道。
步骤102中,在第一时域资源上传输第二上行信道的含义为:在为第二上行信道配置的与第一时域资源对应的资源上传输信息,该信息为第二上行信道在第一时域资源所对应的资源上承载的信息。步骤102中,在第一时域资源上传输第一上行信道的含义为:在为第一上行信道分配的与第一时域资源对应的资源上传输SR。其中,为第二上行信道配置的与第一时域资源对应的资源和为第一上行信道配置的与第一时域资源对应的资源是不同的。
其中,为第二上行信道配置的与第一时域资源对应的资源包括一个或多个资源单元。为第二上行信道配置的与第一时域资源对应的资源单元是基站预先配置的,或者预先配置在终端中的。
其中,为第一上行信道配置的与第一时域资源对应的资源包括一个或多个资源单元。为第一上行信道分配的与第一时域资源对应的资源是基站预先配置的,或者预先配置在终端中的。
上述方法流程中,终端为第一上行信道和第二上行信道占用的相同的时域资源上分配第一传输功率和第二传输功率,使得在第一上行信道和第二上行信道在相同的时域资源上能够同时传输,并且根据相同的时域资源在第二上行信道占用的时域资源中具有的传输特点,配置的第一传输功率和第二传输功率有所不同,解决了现有技术中存在的仅承载SR的短时长PUCCH与其他的上行信道在同一时域资源上冲突时的信号无法同时传输问题。
在一种实施场景中,第二上行信道为PUSCH,PUSCH的长度不做限定。
在此实施场景中,由于PUSCH的功能是传输DMRS和数据,因此,根据包含在PUSCH的时域资源中的第一时域资源的不同情形,步骤102中,终端采用第二传输功率 在第一时域资源上传输第二上行信道也包括不同情形,例如,如果包含在PUSCH的时域资源中的第一时域资源只包括DMRS符号,终端采用第二传输功率在第一时域资源上传输DMRS,如果包含在PUSCH的时域资源中的第一时域资源只包括数据符号,终端采用第二传输功率在第一时域资源上传输数据,如果包含在PUSCH的时域资源中的第一时域资源既包括DMRS符号又包括数据符号,终端采用第二传输功率在第一时域资源上传输DMRS和数据。
在此实施场景中,根据包含在PUSCH的时域资源中的第一时域资源的不同情形,第一传输功率和第二传输功率也具有不同的配置。
可选的,当第一上行信道占用的第一时域资源与PUSCH上承载第一个DMRS的时域资源相同时,第一传输功率不小于SR需要的传输功率,第二传输功率为终端在第一时域资源上的总传输功率与第一传输功率的差值。
例如,第一上行信道占用1个符号长度的时域资源传输SR,PUSCH占用1个符号或2个符号长度的时域资源传输DMRS,当第一上行信道上承载SR的符号与PUSCH上承载DMRS的第一个符号在时域上相同时,当DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P时,终端将在相同的符号上的总传输功率P配置成第一传输功率P1和第二传输功率(P-P1),其中,P1至少能够满足第一上行信道承载的SR的传输需求。对于第二传输功率(P-P1),可能满足PUSCH的承载的DMRS的传输需求,也可能不满足PUSCH的承载的DMRS的传输需求。
可选的,当第一上行信道占用的第一时域资源与PUSCH上承载第二个DMRS的时域资源相同时,第二传输功率与第一个DMRS的传输功率相同,第一传输功率为终端在第一时域资源上的总传输功率与第二传输功率的差值。
例如,第一上行信道占用1个符号长度的时域资源传输SR,PUSCH占用2个符号长度的时域资源传输DMRS,当第一上行信道上承载SR的符号与PUSCH上承载DMRS的第二个符号在时域上相同时,当DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P时,终端将相同的符号上的总传输功率P配置成第一传输功率(P-P0)和第二传输功率(P0),其中,P0为PUSCH上承载DMRS的第一个符号上的传输功率,P0至少能够满足PUSCH上承载DMRS的传输需求。对于第一传输功率(P-P0),可能满足第一上行信道上承载SR的传输需求,也可能不满足第一上行信道上承载SR的传输需求。
可选的,当第一上行信道占用的第一时域资源与PUSCH上承载数据的时域资源相同,且承载数据的时域资源上承载PT-RS时,第一传输功率不小于SR需要的传输功率,第二传输功率为终端在第一时域资源上的总传输功率与第一传输功率的差值。对于基站来说,通过比较不同数据符号上PT-RS所占用的频域资源上的传输功率的变化量,来获取数据符号上传输功率的变化。
例如,第一上行信道占用1个符号长度的时域资源传输SR,PUSCH占用2~13个符号长度的时域资源传输数据,当第一上行信道上承载SR的符号与PUSCH上承载数据的其中一个符号在时域上重合时,当DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P时,如果PUSCH占用的2~13个符号长度的时域资源上还承载PT-RS,终端将重合符号上的总传输功率P配置成第一传输功率P1和第二传输功率(P-P1)。对于第二传输功率(P-P1),可能满足PUSCH的承载的DMRS的传 输需求,也可能不满足PUSCH的承载的DMRS的传输需求。
可选的,当第一上行信道占用的第一时域资源与PUSCH上承载数据的时域资源相同,且承载数据的时域资源上没有承载PT-RS,第二传输功率与PUSCH上承载DMRS的时域资源的传输功率相同,第一传输功率为终端在第一时域资源上的总传输功率与第二传输功率的差值。这样,由于数据符号上的传输功率与DMRS的传输功率相同,对于基站侧来说,无论是否具有符号上传输功率的识别能力,都不会译码错误,可以避免基站侧因PUSCH上不同符号上的传输功率的不同而导致的译码错误。
例如,第一上行信道占用1个符号长度的时域资源传输SR,PUSCH占用1~13个符号长度的时域资源传输数据,当第一上行信道上承载SR的符号与PUSCH上承载数据的其中一个符号在时域上重合时,当DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P时,如果PUSCH占用的1~13个符号长度的时域资源上没有承载PT-RS,终端将重合符号上的总传输功率P配置成第一传输功率(P-P0)和第二传输功率(P0)。对于第一传输功率(P-P0),可能满足第一上行信道上承载SR的传输需求,也可能不满足第一上行信道上承载SR的传输需求。
在5G系统中,PUSCH占用的时域资源的符号长度不做限制,可以是长时长,也可以是短时长,PUSCH占用的时域资源的符号长度可以在终端中预先配置,也可以是基站指示给终端。在5G系统中,SR的周期较短,并且可以根据不同的服务进行灵活配置,SR的周期包括至少一个符号长度,SR的周期可以在终端中预先配置,也可以是基站指示给终端。
在5G系统中,由于PUSCH占用的时域资源的长度和SR的周期都可灵活配置,因此,有可能第一上行信道承载SR的符号只与PUSCH上承载DMRS的符号重合,有可能第一上行信道承载SR的符号只与PUSCH上承载数据的符号重合,也有可能第一上行信道承载SR的符号与PUSCH上承载DMRS的符号和承载数据的符号都重合,因此,在具体的实施场景中,第一传输功率和第二传输功率的配置方式可以涵盖上述几种可选的配置方式中的其中一种,也可以涵盖上述几种可选的配置方式中的任意两种或者三种的组合。
对于上述几种可选的配置方式,如果第一上行信道上承载SR的符号与PUSCH上承载DMRS的符号在时域上重合,且按照SR的周期,PUSCH上位于DMRS符号之后的某个数据符号不会与第一上行信道在下一周期承载的SR的符号重合,那么对于PUSCH上位于DMRS符号之后的数据符号上所承载数据的传输功率有以下配置:
可选的,数据符号上承载的数据的传输功率与第二传输功率相同。
例如,假如DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P。如图3中的(1)所示,承载的SR的PUCCH与PUSCH承载DMRS的第一个符号重复时,为SR分配的传输功率可以为P1,为DMRS分配的传输功率可以是P-P1,数据符号上承载的数据的传输功率可以为P-P1。如图3中的(2)所示,承载的SR的PUCCH与PUSCH承载DMRS的第二个符号重复时,第一个DMRS的传输功率可以为P0,为SR分配的传输功率可以为P-P0,为DMRS分配的传输功率可以为P0,数据符号上承载的数据的传输功率可以为P0。
可选的,如果PUSCH上位于重合符号之后的数据符号上承载有PT-RS,则每一数据符号上承载的数据的传输功率相对于第二传输功率按照设定比例增加。对于基站来说, 要么可以识别数据符号上传输功率的提高量,要么通过比较PT-RS和DMRS在相同频域资源上的传输功率的变化量,来获取数据符号上传输功率的提高量。
例如,假如DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P。如图4中的(1)所示,承载的SR的PUCCH与PUSCH承载DMRS的第一个符号重复时,为SR分配的传输功率可以为P1,为DMRS分配的传输功率可以为P-P1,数据符号上承载的数据的传输功率可以为x*(P-P1)其中,x大于或等于1,x为整数或非整数。或者如图4中的(2)所示,承载的SR的PUCCH与PUSCH承载DMRS的第二个符号重复时,第一个DMRS的传输功率可以为P0,为SR分配的传输功率可以为P-P0,为DMRS分配的传输功率可以为P0,数据符号上承载的数据的传输功率可以为x*P0。
可选的,如果位于重合符号之后的数据符号上没有承载PT-RS,在基站不能识别PUSCH在数据符号上的传输功率的变化的前提下,数据符号上承载的数据的传输功率保持与第二传输功率相同。具体示例可以参见图3中的(1)或图3中的(2)。
对于上述几种可选的配置方式,如果第一上行信道上承载SR的符号与PUSCH上承载DMRS的符号在时域上重合,且按照SR的周期,PUSCH上位于DMRS符号之后的某个数据符号可能与下一周期内第一上行信道上承载SR的符号重合,那么对于PUSCH上位于DMRS符号之后的数据符号上所承载数据的传输功率有以下配置:
可选的,在基站不能识别PUSCH在数据符号上的传输功率的变化的前提下,如果位于重合符号之后的数据符号上承载PT-RS,下一周期第一上行信道上承载SR的传输功率为SR所需的传输功率,相同的数据符号上的传输功率为终端在数据符号上的总传输功率与下一周期第一上行信道上承载SR的传输功率的差值,其余数据符号上的数据的传输功率可以与DMRS的传输功率相同,也可以是相对于DMRS的传输功率等比例增加。对于基站来说,可以通过比较不同数据符号上PT-RS所占用的频域资源上的传输功率的变化量,来获取数据符号上传输功率的变化。
例如,假如DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P。如图5中的(1)所示,承载的SR的PUCCH与PUSCH承载DMRS的第一个符号重复时,在第一个符号上为SR分配的传输功率可以为P1,在第一个符号上为DMRS分配的传输功率可以为P-P1,假如根据SR的周期,下一周期承载SR的PUCCH与其中一个数据符号重复时,下一周期承载SR的PUCCH的传输功率可以为P1,该数据符号上的传输功率可以为P-P1,其余的数据符号上承载的数据的传输功率可以为P-P1。如图5中的(2)所示,承载的SR的PUCCH与PUSCH承载DMRS的第二个符号重复时,第一个DMRS的传输功率可以为P0,为SR分配的传输功率可以为P-P0,为DMRS分配的传输功率是可以为P0,假如根据SR的周期,下一周期承载SR的PUCCH与其中一个数据符号重复时,下一周期承载SR的PUCCH的传输功率可以为P1,该数据符号上的传输功率可以为P-P1,其余的数据符号上承载的数据的传输功率可以为P0。
可选的,在基站不能识别PUSCH在数据符号上的传输功率的变化的前提下,如果位于重合符号之后的数据符号上没有承载PT-RS,数据符号承载的数据的传输功率保持为PUSCH上承载的DMRS需求的传输功率,下一周期第一上行信道上承载SR的符号的传输功率为终端在数据符号上的总传输功率与重合数据符号上的传输功率的差值。
例如,假如PUSCH与PUCCH无冲突时DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P。如图6中的(1)所示,承载的SR的PUCCH与PUSCH承载DMRS的第一个符号重复时,在第一个符号上为SR分配的传输功率可以为P1,在第一个符号上为DMRS分配的传输功率可以P-P1,假如根据SR的周期,下一周期承载SR的PUCCH与其中一个数据符号重复时,下一周期承载SR的PUCCH的传输功率可以为P-P0,该相同的数据符号上的传输功率可以为P0,其余的数据符号上承载的数据的传输功率都可以为P-P1。如图6中的(2)所示,承载的SR的PUCCH与PUSCH承载DMRS的第二个符号重复时,第一个DMRS的传输功率可以为P0,为SR分配的传输功率可以为P-P0,为DMRS分配的传输功率可以为P0,假如根据SR的周期,下一周期承载SR的PUCCH与其中一个数据符号重复时,下一周期承载SR的PUCCH的传输功率可以为P-P0,该数据符号上的传输功率可以为P0,其余的数据符号上承载的数据的传输功率可以为P0。
可选的,在基站能够识别PUSCH在数据符号上的传输功率的变化的前提下,如果位于重合符号之后的数据符号上没有承载PT-RS,则下一周期第一上行信道上承载SR的传输功率为SR所需的传输功率,数据符号上的传输功率为终端在数据符号上的总传输功率与下一周期第一上行信道上承载SR的传输功率的差值。
例如,假如PUSCH与PUCCH无冲突时DMRS所需的传输功率为P0,SR所需的传输功率为P1,终端在每个符号上的总传输功率为P。如图7中的(1)所示,承载的SR的PUCCH与PUSCH承载DMRS的第一个符号重复时,在第一个符号上为SR分配的传输功率可以为P1,在第一个符号上为DMRS分配的传输功率可以为P-P1,假如根据SR的周期,下一周期承载SR的PUCCH与其中一个数据符号重复时,下一周期承载SR的PUCCH的传输功率可以为P1,该相同的数据符号上的传输功率可以为P-P1,其余的数据符号上承载的数据的传输功率可以为P-P1。如图7中的(2)所示,承载的SR的PUCCH与PUSCH承载DMRS的第二个符号重复时,第一个DMRS的传输功率可以为P0,为SR分配的传输功率可以为P-P0,为DMRS分配的传输功率可以为P0,假如根据SR的周期,下一周期承载SR的PUCCH与其中一个数据符号重复时,下一周期承载SR的PUCCH的传输功率可以为P1,该相同的数据符号上的传输功率可以为P-P1,其余的数据符号上承载的数据的传输功率可以为P0。
在另一种实施场景中,第二上行信道为PUCCH,第二上行信道可以是长时长的PUCCH,如图17所示,还可以是短时长的PUCCH,如图18所示。例如,长时长的PUCCH为包括4到14个符号长度的PUCCH,短时长的PUCCH可以是1符号长度的PUCCH,或者2符号长度的PUCCH。此种实施场景中,步骤102中终端采用第二传输功率在第一时域资源上传输第二上行信道,是指终端在为第二上行信道分配的与第一时域资源对应的资源上传输第二上行信道在第一时域资源上承载的上行控制信息。
需要说明的是,长时长的PUCCH承载的信息可以是除了SR以外的上行控制信息,如ACK/NACK、CQI等,也可以是SR和这些上行控制信息,但长时长的PUCCH不含仅承载SR的情况。短时长的PUCCH承载的信息可以是除了SR以外的上行控制信息,如ACK/NACK、CQI等,也可以是SR和这些上行控制信息,本申请中,短时长的PUCCH不含仅承载SR的情况。
需要说明的是,长时长的PUCCH分为使用OCC进行多用户复用和不使用OCC两种, 在使用OCC时,由于不同用户需要通过不同的码字去掉其他用户的干扰,所以各符号承载的信息的传输功率要求不改变。短时长的PUCCH分为单符号的、两符号联合编码的、两符号使能OCC三种。其中,短时长的PUCCH若为两符号使能OCC,为了避免多用户间的干扰,各符号承载的信息的传输功率要求不改变。
在第二上行信道是长时长的PUCCH(如图17所示)的实施场景中,针对包含在第二上行信道占用的时域资源中的第一时域资源的不同情形,终端为第一上行信道和第二上行信道分别分配的第一传输功率和第二传输功率也具有不同的配置,具体如下:
可选的,当第二上行信号使用正交覆盖码OCC,且第一时域资源与第二上行信道的起始时域资源或者跳频的起始时域资源相同时,第一传输功率不小于SR需要的传输功率,第二传输功率为终端在第一时域资源上的总传输功率与第一传输功率的差值。
例如,长时长的PUCCH占用14个符号,第一上行信道占用1个符号,假如SR所需的传输功率为P1,长时长的PUCCH在每个符号上的传输功率为P2,终端在长时长的PUCCH的每个符号上的总传输功率为P。当第一上行信道承载SR的符号与长时长的PUCCH的第1个符号重合时,为SR分配的传输功率可以为P1,为长时长的PUCCH在第1个符号上承载的上行控制信息分配的传输功率可以为P-P1,对于第2个符号至第7个符号上承载的上行控制信息的传输功率与第1个符号上承载的信息的传输功率相同,都可以为P-P1。或者当第一上行信道承载SR的符号与长时长的PUCCH的第8个符号重合时,为SR分配的传输功率可以为P1,为长时长的PUCCH在第8个符号上承载的上行控制信息分配的传输功率可以为P-P1,对于第9个符号至第14个符号上承载的上行控制信息的传输功率与第8个符号上承载的信息的传输功率相同,都可以为P-P1。
可选的,当第二上行信号使用OCC,且第一时域资源与第二上行信道的起始时域资源之后的时域资源或者跳频的起始时域资源之后的时域资源相同时,第二传输功率与终端在起始时域资源上的传输功率相同,第一传输功率为终端在第一时域资源上的总传输功率与第二传输功率的差值。
例如,长时长的PUCCH占用14个符号,第一上行信道占用1个符号,假如SR所需的传输功率为P1,长时长的PUCCH在每个符号上的传输功率为P2,终端在每个符号上的总传输功率为P。当第一上行信道承载SR的符号与长时长的PUCCH的第2个符号重合时,为SR分配的传输功率可以为P-P2,长时长的PUCCH的所有符号上承载的信息的传输功率可以为P2。或者当第一上行信道承载SR的符号与长时长的PUCCH的第9个符号重合时,为SR分配的传输功率可以为P-P2,长时长的PUCCH的所有符号上承载的信息的传输功率可以为P2。
可选的,当第二上行信号不使用OCC,第一传输功率不小于SR需要的传输功率,第二传输功率为终端在第一时域资源上的总传输功率与第一传输功率的差值。
例如,长时长的PUCCH占用14个符号,第一上行信道占用1个符号,假如SR所需的传输功率为P1,长时长的PUCCH在每个符号上的传输功率为P2,终端在每个符号上的总传输功率为P。当长时长的PUCCH不使用OCC进行多用户复用时,当第一上行信道承载SR的符号与长时长的PUCCH的某个符号重合时,为SR分配的传输功率至少为P1,为长时长的PUCCH在重复符号上承载的上行控制信息分配的传输功率为P-P1。可选的,长时长的PUCCH在其他符号上的传输功率可以是P2,也可以是P-P1。
在5G系统中,由于SR的周期可灵活配置,因此,有可能第一上行信道与长时长的 PUCCH在PUCCH占用的符号长度内冲突一次,也有可能第一上行信道与长时长的PUCCH在PUCCH占用的符号长度内冲突多次,因此,在另一实施场景中,包含在第二上行信道占用的时域资源中的第一时域资源的情形可能是上述几种情形的任意组合。例如,第一上行信道上承载SR的符号与长时长的PUCCH的符号的重复位置可能包括长时长的PUCCH的第一个符号、跳频的第一个符号、除第一个符号或者除跳频的第一个符号以外的某个符号中的一种或任意两种或三种的组合。那么第一传输功率和第二传输功的配置方式可以涵盖上述几种可选的配置方式中的其中一种,也可以涵盖上述几种可选的配置方式中的任意组合。
在第二上行信道是短时长的PUCCH且采用跳频传输的实施场景中,针对包含在第二上行信道占用的时域资源中的第一时域资源的不同情形,第一传输功率和第二传输功率具有不同的配置,具体如下:
可选的,第一传输功率不小于SR需要的传输功率,第二传输功率为终端在第一时域资源上的总传输功率与第一传输功率的差值。
可选的,第二传输功率不小于第二上行信道需要的传输功率,第一传输功率为终端在第一时域资源上的总传输功率与第二传输功率的差值。
可选的,第一传输功率和第二传输功率相等,第一传输功率和第二传输功率是终端按照平均分配的原则将终端在第一时域资源上的总传输功率进行分配。
可选的,第一传输功率和第二传输功率按照SR与第二上行信道上承载的上行控制信息的信息量比值对总功率进行分配。
在第二上行信道是短时长的PUCCH(如图18所示),且使用正交覆盖码OCC进行多用户复用的实施场景中,针对包含在第二上行信道占用的时域资源中的第一时域资源的不同情形,第一传输功率和第二传输功率具有不同的配置,具体如下:
可选的,当第一时域资源与第二上行信道的第一个时域资源(如第一个符号)相同时,第一传输功率不小于第一上行信道需要的传输功率,第二传输功率为终端在第一时域资源上的总传输功率与第一传输功率的差值;或者,第二传输功率不小于第二上行信道需要的传输功率,第一传输功率为终端在第一时域资源上的总传输功率与第二传输功率的差值。
可选的,当第一时域资源与第二上行信道的位于所述第一个时域资源之后的时域资源(如第二个符号)相同时,第二传输功率与第二上行信道的第一个时域资源的传输功率相同,第一传输功率为终端在第一时域资源上的总传输功率与第二传输功率的差值。
在5G系统中,由于SR的周期可灵活配置,因此,有可能第一上行信道的时域资源与短时长的PUCCH占用的时域资源内冲突一次,也有可能第一上行信道与短时长的PUCCH在PUCCH占用的符号长度内冲突多次,因此,在另一实施场景中,包含在第二上行信道占用的时域资源中的第一时域资源的情形可能是上述几种情形的任意组合,第一传输功率和第二传输功的配置方式可以涵盖上述几种可选的配置方式中的其中一种,也可以涵盖上述几种可选的配置方式中的任意组合。
可选的,对于上述几种实施场景中第一传输功率和第二传输功率的任意一种配置,若第二传输功率小于第二上行信道需要的传输功率,则终端在第一时域资源上传输SR。
可选的,在SR传输完成之后,终端传输第二上行信道,或者第二上行信道的传输功率为0。
例如,当第二上行信道为PUCCH时,若第二传输功率小于第二上行信道需要的传输功率,则终端在第一时域资源上传输SR,在SR传输完成之后,若第二上行信道未传输的时域资源上或者已传输的时域资源上同时包括分别承载DMRS和上行控制信息(如UCI)的时域资源,则终端传输第二上行信道。在SR传输完成之后,若第二上行信道未传输的时域资源上或者已传输的时域资源上不同时包括承载DMRS和上行控制信息的时域资源,则第二上行信道的传输功率为0。
可选的,对于上述几种实施场景中第一传输功率和第二传输功率的任意一种配置,若第一传输功率小于第一上行信道需要的传输功率,则终端在第一时域资源上传输第二上行信道。
可选的,对于上述几种实施场景中第一传输功率和第二传输功率的任意一种配置,对于第二上行信道上与第一上行信道的第一时域资源不相同的时域资源上所承载信息的传输功率与第二传输功率相同。
可选的,对于上述几种实施场景中第一传输功率和第二传输功率的任意一种配置,第二上行信道上与第一上行信道的第一时域资源不相同的时域资源上所承载信息的传输功率相对于第二传输功率等比例增加。
在5G系统中,由于SR的周期可灵活配置,因此,有可能第一上行信道的时域资源与PUSCH的部分或全部时域资源冲突,有可能第一上行信道的时域资源与长时长的PUCCH的部分或全部时域资源冲突,有可能第一上行信道的时域资源与短时长的PUCCH的部分或全部时域资源冲突,也有可能第一上行信道的时域资源同时与PUSCH、长时长的PUCCH或短时长的PUCCH中的一个或任意两个或任意三个冲突。因此,包含在第二上行信道占用的时域资源中的第一时域资源的情形可能是上述几种实时场景中出现的不同情形的任意组合,第一传输功率和第二传输功的配置方式可以涵盖上述几种实施场景中的配置方式中的其中一种,也可以涵盖上述几种实时场景中的配置方式中的任意组合。
为了解决冲突的时域资源上的信号传输问题,本申请还提供另一种上行传输方法,主要包括以下步骤:
步骤201,终端获取第一时域资源和第一频域资源,获取第二时域资源和第二频域资源。
第一频域资源和第二频域资源都包含在基站为某个PUSCH配置的频域资源内,第二时域资源包含在第一时域资源内。其中,第一频域资源与第一时域资源存在映射关系,第一频域资源与第一时域资源用于传输PUSCH所承载的信息,第二频域资源与第二时域资源存在映射关系,第二域资源与第二时域资源用于发送SR。
步骤202,终端使用第一时域资源和第一频域资源发送信息,此信息包括PUSCH所承载的DMRS和/或数据;终端使用第二时域资源和第二频域资源发送调用请求SR。
步骤202中终端使用第一频域资源和第一时域资源发送信息包括以下情形:
终端使用第一频域资源和第一时域资源发送PUSCH的DMRS,或者,终端使用第一频域资源和第一时域资源发送PUSCH的数据,或者,终端使用第一频域资源和第一时域资源发送PUSCH的DMRS和数据。
其中,第一时域资源与第二时域资源之间的可能满足的关系如下:
第二时域资源的全部时域资源与第一时域资源的全部或部分时域资源相同,或者, 第二时域资源的部分时域资源与第一时域资源的全部或部分时域资源相同。
需要指出的是,第一时域资源的长度是指PUCCH占用的符号长度,是基站预先配置给终端的,或者预先存储在终端内的。可以是1符号长度,也可以是2符号长度,也可以是大于2符号长度。
需要指出的是,SR是周期性发送的,第二时域资源的符号长度,与SR的周期和每个SR占用的符号长度有关。可选的,每个SR占用的符号长度为1符号长度或2符号长度。
本申请中,SR的周期可灵活配置,SR的周期是基站预先配置给终端的,或者预先存储在终端内的。例如,SR的周期可以是1符号长度,也可以是大于或等于2符号长度。如果SR的周期大于或者等于第一时域资源的长度,在第一时域资源的长度内,可能会有1个发送SR的周期,此时第二时域资源的长度为1个SR占用的符号长度。如果SR的周期小于第一时域资源的长度,在第一时域资源的长度内,可能会有多个发送SR的周期,此时第二时域资源的长度大于1符号长度,或者大于2符号长度。
本申请中,终端发送PUSCH的DMRS的时域资源可能与终端发送SR的时域资源在时域上相同,或者,终端发送PUSCH的数据的时域资源可能与终端发送SR的时域资源在时域上相同,或者终端发送PUSCH的数据的时域资源,以及终端发送PUSCH的DMRS的时域资源都有可能与发送SR的时域资源在时域上相同。将SR承载在PUSCH中传输时,结合SR的周期,终端可以在PUSCH的一个或多个数据符号上发送SR,或者终端可以在PUSCH的一个或两个DMRS符号上发送SR,或者终端既在一个或多个数据符号上发送SR,又在一个或两个DMRS符号上发送SR。
可选的,第二时域资源的全部时域资源与第一时域资源的全部时域资源相同,即第一时域资源和第二时域资源在时域上完全重合。例如,SR的周期为1个符号长度,无论每个SR占用的符号长度为1符号长度或2符号长度,可能在PUSCH的每个符号上都会发送SR,此时第一时域资源的长度与第一时域资源的长度都会相同。
可选的,第二时域资源的全部时域资源与第一时域资源的部分时域资源相同,即第二时域资源的全部时域资源与第一时域资源的部分时域资源在时域上重合。例如,SR的周期为2个符号长度,SR的周期小于第一时域资源的长度,可能在PUSCH的符号长度内每隔两个符号长度都会发送SR,如果每个SR占用的符号长度为1符号长度,SR会在PUSCH的某一些符号上发送,就会存在第二时域资源的全部时域资源与第一时域资源的部分时域资源在时域上重合。
可选的,第二时域资源的部分时域资源与第一时域资源的全部相同,即第二时域资源的部分时域资源与第一时域资源的全部时域资源在时域上重合。例如,SR的周期大于第一时域资源的长度,第二时域资源为2符号长度,第一时域资源的长度为1符号长度,并且第二时域资源的其中1符号长度和第一时域资源的1符号长度在时域上重合。
可选的,第二时域资源的部分时域资源与第一时域资源的部分时域资源相同,即第二时域资源的部分时域资源与第一时域资源的部分时域资源在时域上重合。
例如,SR的周期为2个符号长度,SR的周期小于第一时域资源的长度,可能在PUSCH的符号长度内每隔两个符号长度都会发送SR,如果每个SR占用的符号长度为2符号长度,第二时域资源的第二个符号和第一时域资源的第一个符号在时域上重合,这样SR会在PUSCH的某一些符号上发送,就会存在第二时域资源的部分时域资源与第一 时域资源的部分时域资源在时域上重合。再例如,如果SR的周期大于第一时域资源的长度,第二时域资源的长度为2符号长度,第一时域资源的长度为大于或等于2符号长度,并且第二时域资源的其中1个符号长度与第一时域资源的其中1符号长度在时域上重合。
需要说明的是,以上仅为举例,并不代表所有示例。
上述方法流程中,发送SR的第二时域资源和第二频域资源是从为PUSCH配置的资源中为SR预留的一部分资源,当仅承载SR的PUCCH与PUSCH占用相同的时域资源时,按照上述方法流程实现了将SR承载在PUSCH中传输,进而解决了现有技术中存在的仅承载SR的短时长PUCCH与其他的上行信道在同一时域资源上冲突时的信号传输问题。
根据步骤202中终端使用第一频域资源和第一时域资源发送信息不同情形,第一频域资源与第二频域资源的关系不同。
可选的,当终端使用第一频域资源和第一时域资源发送PUSCH的DMRS时,第一频域资源包括PUSCH的DMRS占用的频域资源,第一时域资源包括PUSCH的DMRS占用的时域资源。此时,第二频域资源的全部频域资源与第一频域资源的全部或部分频域资源相同,或者,第二频域资源的部分频域资源与第一频域资源的全部或部分频域资源相同。
例如,如图8中的(1)和(4)所示,SR占用的频域资源可以与DMRS占用的全部频域资源相同,或者,SR占用的频域资源可以与DMRS占用的部分频域资源相同。如图8中的(2)所示,SR占用的频域资源与第一个DMRS占用的部分频域资源或者全部频域资源相同,如图8中的(3)所示,SR占用的频域资源与第二个DMRS占用的部分频域资源或者全部频域资源相同。
可选的,当终端使用第一频域资源和第一时域资源发送PUSCH的数据时,第一频域资源包括PUSCH的数据占用的频域资源,第一时域资源包括PUSCH的数据占用的时域资源。此时,第一频域资源与第二频域资源不同。
其中,第二频域资源是从基站为PUCCH配置的频域资源中预留出的专门用来发送SR的频域资源,剩余的频域资源为第一频域资源。因此,第二频域资源与第一频域资源不同是指在基站为PUCCH配置的频域资源中,第一频域资源和第二频域资源不同。此外,还可从频域资源对应的使用频率上来理解第一频域资源和第二频域资源不同,即第二频域资源的频率大于或等于第一频域资源的最小频率,且第二频率资源的频率小于或等于第一频域资源的最大频率。
可选的,当终端使用第一频域资源和第一时域资源发送PUSCH的DMRS和数据时,第一频域资源包括PUSCH的DMRS占用的频域资源和PUSCH的数据占用的频域资源,第一时域资源包括PUSCH的DMRS占用的时域资源和PUSCH的数据占用的时域资源。此时第一频域资源和第二频域资源可以部分相同。
在一种实施场景中,当终端发送PUSCH的DMRS的时域资源与终端发送SR的时域资源在时域上相同时,终端使用相同的时域资源所对应的频域资源来同时发送DMRS和SR。
其中,DMRS占用的时域资源与SR所占用的时域资源相同,主要包括以下几种情况:
其一,假如一个SR占用的符号长度为1符号长度,DMRS占用的符号长度为1符号长度,DMRS占用的1符号长度与SR占用的1符号长度在时域上相同,则在相同的1符号长度内,DMRS占用的频域资源可以和SR占用频域资源相同,或者DMRS占用的部 分频域资源和SR占用频域资源相同。例如,如图8中的(1)所示,SR和DMRS都承载在PUSCH的DMRS符号中,DMRS符号占用1个符号长度,SR和DMRS占用的频域资源相同。
其二,假如一个SR占用的符号长度为1符号长度,DMRS占用的符号长度为2符号长度,并且SR占用的1符号长度和DMRS占用的第一个符号的符号长度在时域上相同,则在相同的1符号长度内,DMRS占用的部分频域资源和SR占用的频域资源相同。例如,如图8中的(2)所示,DMRS占用PUSCH的2个符号长度,SR和DMRS都承载在PUSCH的第一个DMRS符号中,SR占用的频域资源可以与第一个DMRS占用的一部分频域资源相同,也可以与第一个DMRS占用的全部频域资源相同,第二个DMRS符号只承载DMRS。
其三,假如一个SR占用的符号长度为1符号长度,DMRS占用的符号长度为2符号长度,并且SR占用的1符号长度和DMRS占用的第二个符号的符号长度在时域上相同,则在相同的1符号长度内,DMRS占用的部分频域资源和SR占用频域资源相同。例如,如图8中的(3)所示,DMRS占用PUSCH的2个符号长度,第一个DMRS符号只承载DMRS,第二个DMRS符号承载SR和DMRS,SR占用的频域资源可以与第二个DMRS占用的部分频域资源相同,也可以与第二个DMRS占用的全部频域资源相同。
其四,假如一个SR占用的符号长度为2符号长度,DMRS占用的符号长度为2符号长度,SR占用的2符号长度和DMRS占用的2符号长度在时域上相同,则在相同的2符号长度内,DMRS占用的频域资源和SR占用频域资源相同。例如,如图8中的(4)所示,DMRS占用PUSCH的2个符号长度,第一个DMRS符号承载SR和DMRS,第二个DMRS符号承载SR和DMRS,SR占用的频域资源可以和DMRS占用的频域资源相同,也可以和DMRS占用的部分频域资源相同。
其五,假如一个SR占用的符号长度为2符号长度,DMRS占用的符号长度为2符号长度,并且SR占用的第一个符号的符号长度和DMRS占用的第二个符号的符号长度在时域上相同,则在相同的1符号长度内,DMRS占用的频域资源和SR占用频域资源相同。例如,如图8中的(5)所示,DMRS占用PUSCH的2个符号长度,第一个DMRS符号只承载DMRS,第二个DMRS符号承载SR和DMRS,SR占用的频域资源可以与第二个DMRS占用的部分频域资源相同,也可以与第二个DMRS占用的全部频域资源相同,第二个DMRS符号之后的第一个数据符号上承载数据和SR,但是数据和SR占用的频域资源不同。
可选的,当DMRS占用的时域资源与SR所占用的时域资源相同时,在相同的时域资源上,终端使用第一序列发送DMRS,使用第二序列发送SR,第一序列与第二序列不同。
需要说明的是,第一时序和第二时序在整个PUSCH上正交。或者第一时序和第二时序在重复的DMRS符号上正交。
可选的,当DMRS占用的时域资源与SR所占用的时域资源相同时,在相同的时域资源上,终端采用第一传输功率发送DMRS,终端采用第二传输功率发送SR。
可选的,在所述终端不使用所述第二时域资源和所述第二频域资源发送所述SR时,所述第二传输功率为0,所述第一传输功率不小于所述DMRS所需的传输功率。
可选的,如果DMRS为1个,当第二时域资源与DMRS占用的第一个时域资源相同时,第二传输功率不小于传输SR需要的传输功率,第一传输功率为终端在第二时域资源 上的总传输功率与第二传输功率的差值。
可选的,如果DMRS为两个,当第二时域资源与第一个DMRS占用时域资源相同时,第二传输功率不小于传输SR需要的传输功率,第一传输功率为终端在第二时域资源上的总传输功率与第二传输功率的差值;或者,
可选的,如果DMRS为两个,当第二时域资源与第二个DMRS占用的时域资源相同时,第一传输功率与第一个DMRS的传输功率相同,第二传输功率为终端在第二时域资源上的总传输功率与第一传输功率的差值。
假如SR需要的传输功率为P1,DMRS需要的传输功率为P0,终端在每个符号长度上的总传输功率为P,对于如图8中(1)所示的情况,终端在DMRS符号上使用第二序列发送SR,终端在DMRS符号上使用第一序列发送DMRS,发送SR的传输功率大于或等于P1,发送DMRS的传输功率小于或等于P-P1。
对于如图8中(2)所示的情况,终端在第一个DMRS符号上使用第二序列发送SR,终端在第一个DMRS符号上使用第一序列发送第一个DMRS,发送SR的传输功率大于或等于P1,发送第一个DMRS的传输功率小于或等于P-P1。终端在第二个DMRS符号上发送第二个DMRS,可选的,发送第二个DMRS的传输功率可以和发送第一个DMRS的传输功率相同。
对于如图8中(3)所示的情况,终端在第一个DMRS符号上发送第一个DMRS,可选的,发送第一个DMRS的传输功率至少为P0。终端在第二个DMRS符号上使用第二序列发送SR,终端在第二个DMRS符号上使用第一序列发送第二个DMRS,发送SR的传输功率为P-P0,发送第二个DMRS的传输功率与发送第一个DMRS的传输功率相同,即为P0。
对于如图8中(4)所示的情况,终端在第一个DMRS符号和第二个DMRS符号上使用第二序列发送SR,终端在第一个DMRS符号和第二个DMRS符号上使用第一序列发送DMRS,发送SR的传输功率大于或等于P1,发送DMRS的传输功率小于或等于P-P1。
对于如图8中(5)所示的情况,终端在第一个DMRS符号上发送第一个DMRS,可选的,发送第一个DMRS的传输功率至少为P0。终端在第二个DMRS符号上使用第二序列发送SR,终端在第二个DMRS符号上使用第一序列发送第二个DMRS,发送SR的传输功率为P-P0,发送第二个DMRS的传输功率与发送第一个DMRS的传输功率相同,即为P0,终端还在第二个DMRS符号之后的数据符号上发送SR和数据,但是SR和数据占用的频域资源不同。
在另一种实施场景中,当终端发送数据的部分或全部时域资源与终端发送SR的时域资源在时域上相同时,终端在相同的时域资源上分别采用不同的资源发送SR和数据。换言之,在所述数据与所述SR占用的相同时域资源所对应的资源中,所述数据占用的资源与所述SR占用的资源不同。所述SR占用的资源的频率大于或等于所述数据占用的资源的最小频率,且所述数据占用的资源的频率小于或等于所述所述数据占用的资源的最大频率。
当终端发送数据的某些时域资源与终端发送SR的时域资源在时域上相同时,所述数据与所述SR占用的相同时域资源所对应的资源中,所述SR占用的资源包括一个或多个资源组,每个资源组包括一个RE或至少两个连续的RE。
其中,终端在PUSCH的某些数据符号上发送SR时,在该数据符号对应的资源中,承载数据符号的资源组和承载SR的资源组位于不同的频域资源上。如图9中的(1)和(2)所示,终端在PUSCH的至少2个数据符号上承载SR,并且承载SR和承载数据的资源不同。承载SR的资源可以与PT-RS占用的频域资源相邻设置,可以设置在PT-RS占用的频域资源的相同侧,也可以设置在PT-RS占用的频域资源的不同侧。
为了提高SR的传输可靠性,在同一符号对应的资源中,承载SR的资源组也可以是两个,或者两个以上。
可选的,所述SR占用的频域资源包括多个资源组时,不同的资源组之间至少间隔一个RE。
例如,终端在PUSCH的其中一个数据符号上发送SR时,在该数据符号对应的资源中承载SR的资源组为3个,这3个资源组之间至少间隔一个RE。
可选的,为了提高调度请求可靠性,可采用频率分集的方式,即在所述相同时域资源上,预留给SR的位于相邻的时域资源上的资源组位于不同的频域资源上。
例如,如果终端在PUSCH上的两个连续的数据符号上发送SR,如果每个数据符号上承载SR的资源组为1个,则这两个连续的数据符号上承载SR的资源组位于不同的频域资源上。
例如,如果终端在PUSCH上的所有数据符号上发送SR,如果每个数据符号上承载SR的资源组为1个,则相邻两个数据符号上承载SR的资源组位于不同的频域资源上。
例如,如果终端在PUSCH上的所有数据符号上发送SR,如果每个数据符号上承载SR的资源组为2个,则相邻两个数据符号上承载SR的4个资源组位于不同的频域资源上。
可选的,若所述信息还包括相位跟踪参考信号,则承载SR的至少一个所述资源组与所述相位跟踪参考信号占用的频域资源相邻。
例如,在PUSCH上的数据符号中承载相位跟踪参考信号,则终端在PUSCH的一个或或者多个数据符号上发送SR时,每个数据符号上承载SR的一个或者多个资源组靠近承载相位跟踪参考信号的频域资源设置。
可选的,在PUSCH上的数据符号中承载相位跟踪参考信号,则终端在PUSCH的一个或或者多个数据符号上发送SR时,每个数据符号上承载SR的多个资源组可以一部分靠近承载相位跟踪参考信号的频域资源设置,一部分靠近子载波编号最小或子载波编号最大的频域资源设置。
前述实施例介绍了终端在PUSCH的一个或两个DMRS符号上发送SR的实施方式和终端在PUSCH的一个或多个数据符号上发送SR的实施方式。在5G系统中,由于SR的周期可灵活配置,当把SR承载在PUSCH中传输时,根据SR的周期,终端可以在PUSCH的一个或多个数据符号上发送SR,终端也可以在PUSCH的一个或两个DMRS符号上发送SR,终端还可以既在一个或多个数据符号上发送SR,又在一个或两个DMRS符号上发送SR。对于终端既在一个或多个数据符号上发送SR,又在一个或两个DMRS符号上发送SR的实施场景,其方案可以是上述两种实时场景所采用的实施方式的组合。
因此,在解决仅承载SR的PUCCH与PUSCH在某一些时域资源上冲突的技术问题时,终端采用将SR承载在PUSCH中传输的方案,可以涵盖上述两种实施场景的方案其中一种,也可以涵盖上述两种实时场景的组合。
现有技术中,承载SR的短时长PUCCH,PUSCH,和其他PUCCH传输方式如下:
现有技术中,承载SR的短时长PUCCH和能够承载一部分上行控制信息的PUSCH不可以同时传输。虽然,在LTE中,当承载SR的长时长控制信道和PUSCH冲突时,由于这两个信道占用相同的时域资源,如果终端能力支持,通过在相同的时域资源上分配功率可实现同时传输,例如,将长时长的PUCCH在每个符号上的传输功率配置为P1,将PUSCH在每个符号上的传输功率配置为P-P1。但是,因为仅承载SR的短时长PUCCH只占用一部分符号,由于仅承载SR的短时长PUCCH占用的符号数可灵活变化,难以给出相关的功率分配方案。
在LTE中,只有一个调度请求的配置,由于LTE系统仅支持一种服务类型,该种服务类型仅对应一个调度请求的资源配置。与LTE不同,在5G系统中,终端可承载多种服务类型,所以目前标准讨论中规定NR可配置多种服务类型,这些服务类型可由长时长的PUCCH承载,也可由短时长的PUCCH承载,或其他承载方式。由于这些服务类型各不相同,其SR的资源也是独立配置的,因此一种服务的调度请求可能和其他的上行信道的时域资源重合,即一个符号上既有SR的传输需求也有其他的上行信道的传输需求。在时延要求极高的情况下,SR的周期可配置为1符号,即在每个符号上都有可能传输SR。在这种情况下,终端如何处理调度请求和其他上行信道的冲突是本发明要解决的问题。
在LTE系统中,现有的PUCCH传输方式调度方法如图10所示。1ms的子帧中在时域上分为两段各0.5ms传输,所传输的位置位于整个频带的两侧,以提高分级增益的效果。具体来讲,1ms包含14个符号,前7个符号在频带的一侧进行传输,后7个符号在频带的另一侧进行传输。
在LTE中,终端发起的SR一般有两种形式,针对两种情况。第一种情况,终端有基站分配的周期性调度请求的资源。在每个周期内,某一个固定的时域、频域和码域资源上,终端可以发送调度请求。第二种情况,终端在回复PUCCH时承载上行调度请求。当基站调度终端传输上行控制信息时,终端可以把上行调度请求的信息和其他信息进行联合编码,然后发送给基站。
在LTE中,如果终端能力支持,承载调度请求的PUCCH是可以和PUSCH同时传输的,此时涉及到两者功率分配的问题。然而,5G NR中出现了短时长PUCCH,与LTE中不同的是,该短时长PUCCH可能只在一部分符号上出现,其余符号上不出现,这样PUSCH不同符号上的功率可能会变化,原来的功率分配方案就不再适用了。
在LTE中,PUSCH可以反馈部分上行控制信息,包括信道质量信息或者之前下行传输的ACK/NACK信息。然而,在NR中,调度请求的周期可能很短,在每个符号上都有可能出现,因此对于PUSCH上如何承载周期短且出现位置不确定的调度请求,原有的方式不再适用。进一步讨论,由于在LTE中仅出现了一种服务类型,对应一种调度请求,所以在传输PUSCH是就是在服务这种服务类型,因此也就没有必要在PUSCH提供承载调度请求。
在LTE中,调度请求可以和其他上行信息联合编码并通过PUCCH传给基站。然而在NR中,由于调度请求的周期可能较短、时延要求比较高、出现位置不确定,因此不能够提前和其他上行信息联合编码。
如前所述,LTE中的现有方式不能解决本发明遇到的周期较短的PUCCH与其他信道冲突的问题。PUSCH和PUCCH同时传输时,由于5G NR可采用短时长PUCCH,即仅 在部分符号同时出现PUSCH和PUCCH,而其他符号仍仅有PUSCH,不利于检测PUSCH,原有的功率分配方式不再适用;在PUSCH承载调度请求在原有LTE中因仅支持一种服务而未有涉及,而5G NR由于引入了多种服务类型,其周期灵活配置,所以在一种服务的PUSCH时另一种服务的调度请求也可能在任何符号出现,这在LTE中是未有考虑的;对于PUCCH承载调度请求和其他UCI并进行联合编码的情况,LTE中联合编码的方案因为需要提前获取调度请求以进行编码,而不能支持时延较低的调度请求而无法满足要求。
本发明要解决仅承载调度请求的PUCCH和其他上行信道在同一时域资源上冲突的问题,所述的仅承载调度请求的PUCCH为短时长PUCCH,其他上行信道包括PUSCH、PUCCH,其中,PUCCH更进一步包括长时长PUCCH、一符号的短时长PUCCH、两符号的短时长PUCCH三种情况。
具体而言,当仅承载调度请求的短时长PUCCH与PUSCH有部分时域资源重合时,分两种情况讨论,第一种是两种信道同时传输并进行功率分配的问题,第二种是两种信道只传输一种信道,即只传输PUSCH并在PUSCH中承载调度请求的信息;当仅承载调度请求的短时长PUCCH与其他PUCCH有部分时域资源重合时,也同样分两种情况讨论,第一种是两种信道同时传输并进行功率分配,第二种是仅传输一种信道,根据一些条件确定是只传输仅承载调度请求的PUCCH,还是只传输其他上行信道。
本申请中,解决仅承载调度请求的短时长PUCCH和其他信道冲突的处理方式,包含以下两个部分:
1)首先,本发明给出了仅承载调度请求的短时长PUCCH与PUSCH共同传输的方式,涉及到和PUSCH起始的1~2个DMRS符号的同时传输和其余承载数据的符号同时传输,并给出了在那些情况下可以同时传输的限定;
2)其次,本发明给出了PUSCH承载调度请求的方式,给出了在任意符号均可传输的方式并给出了采用频率分集的方式提高调度请求可靠性的方法;
3)最后,本发明给出了仅承载调度请求的短时长PUCCH与其他PUCCH之间冲突时如何功率分配、什么条件下仅传输其中一个信道的方法。
针对仅承载调度请求的短时长PUCCH与其他信道出现时域资源重合的问题,本申请提供的第一种处理方案如下:
第一种处理方案为仅承载调度请求的短时长PUCCH与PUSCH共同传输的处理方式。
此种情形下,终端发送PUSCH的期间,需要同时传输调度请求,采用短时长PUCCH仅承载调度请求。此时,由于同时传输两个信道,终端需要基于配置的功率优先级进行分配,优先分配一部分功率给一个信道,其余的功率分配给另一个信道进行传输。具体分配功率的方案要考虑是与承载SR的符号冲突的是DMRS符号,还是DMRS符号后面的承载数据的符号。
当PUSCH中只含有一个DMRS符号,且调度请求在该符号出现时,功率优先分配给调度请求的短时长的PUCCH,其余功率在分配给DMRS。在之后承载数据的符号上,一种方式是,保持和DMRS部分相同的传输功率;另一种方式是,在之后承载数据的符号上,如果PUSCH配有PT-RS,且没有承载SR的短时长PUCCH冲突,则终端可提高数据的传输功率,数据的传输功率相对于DMRS的传输功率等比例提高。对于基站侧来说,要么可以识别功率的提高量,要么基站侧可以通过比较PT-RS和DMRS在相同频域资源 上的功率的差异来获取功率的提高量。
当PUSCH中含有两个DMRS符号,且调度请求在第一个DMRS符号出现时,将一部分功率分配给承载调度请求的短时长的PUCCH,其余功率在分配给DMRS,在第二个DMRS符号仍保持和第一个DMRS符号相同的功率。在之后承载数据的符号上,一种方式是,保持和DMRS部分相同的传输功率;另一种方式是,在之后承载数据的符号上,如果PUSCH配有PT-RS,且没有承载SR的短时长PUCCH冲突,则终端可提高数据的传输功率,数据的传输功率相对于DMRS的传输功率等比例提高,基站侧要么可以识别功率的提高量,要么基站侧可以通过比较PT-RS和DMRS在相同频域资源上的功率的差异来获取功率的提高量。
当PUSCH中含有两个DMRS符号,且调度请求在第二个DMRS符号出现时,如图11所示,将一部分功率分配给DMRS保证第二个DMRS和第一个DMRS的功率相同,其余功率分配给承载调度请求的短时长的PUCCH。在之后承载数据的符号上,一种方式是,保持和DMRS部分相同的传输功率。因为两个DMRS符号用于多个端口的信道测量,如果两个DMRS符号上的功率不相同,就会造成多个端口之间的干扰。另一种方式是,在之后承载数据的符号上,如果PUSCH配有PT-RS,且没有承载SR的短时长PUCCH冲突,则终端可提高数据的传输功率,数据的传输功率相对于DMRS的传输功率等比例提高,基站侧要么可以识别功率的提高量,要么基站侧可以通过比较PT-RS和DMRS在相同频域资源上的功率的差异来获取功率的提高量。
当调度请求与PUSCH上承载数据的符号上出现时,如图12所示,如果PUSCH配有PT-RS,则功率优先分配给承载调度请求的短时长的PUCCH,其余功率分配给PUSCH,对于基站侧来说,要么可以识别功率的大小,要么基站侧可以通过比较前后不同符号上的承载PT-RS的频域资源上的功率,获取在该符号上PUSCH部分的功率大小;如果PUSCH没有PT-RS,则功率优先分配给PUSCH,其余功率分配给承载调度请求的短时长的PUCCH,因为在PUSCH的部分符号的功率下降时,如果基站不知道功率下降值会造成译码错误。
对于PUSCH不含PT-RS的情况,如果在承载DMRS的第一个符号有调度请求出现,功率优先分配给调度请求的短时长的PUCCH,剩余功率分配给DMRS部分。由于没有PT-RS,基站不能准确估计PUSCH功率的提高量,所以在PUSCH承载数据的符号上,保持和DMRS具有相同的功率。如果在PUSCH承载数据的符号上有调度请求,由于基站没有PT-RS估计功率变化量,数据符号上的功率应保持为PUSCH所需的功率,其余功率分配给承载调度请求的短时长的PUCCH。
还有一种情况,如果基站有能力估计因与承载SR的短时长PUCCH同时传输而带来的PUSCH的功率变化量,即基站能力允许,当在PUSCH承载数据的符号上出现调度请求,终端传输时优先把功率分配给承载调度请求的短时长的PUCCH,其余功率分配给PUSCH。
针对仅承载调度请求的短时长PUCCH与其他信道出现时域资源重合的问题,本申请提供的第二种处理方案如下:
第二种处理方式是对于两种信道,只传输一种信道,即将仅传输PUSCH并将SR承载在PUSCH中传输。
PUSCH的结构中包含1~2个DMRS符号以及之后承载上行数据的符号,其中之后承 载上行数据的符号可能配置PT-RS也可能不配置PT-RS。为了支持调度请求可能出现在任何一个符号的情况,PUSCH需要在每个符号上都预留出相应的资源。下面分别针对PUSCH中承载DMRS符号和承载上行数据的符号两部分分别阐释。
当PUSCH只有一个符号的DMRS且DMRS所在符号上有调度请求时,终端采用与传输DMRS不同的序列承载SR,所述SR序列与DMRS序列在整个PUSCH的频带或者两者覆盖的频带上正交;可选的,终端优先提供SR的功率,剩余的功率再用于DMRS的传输,在DMRS之后的符号,如果有PT-RS配置,终端可将PUSCH的功率提升到PUSCH所需的功率,如果没有PT-RS配置,后续的PUSCH符号保持和DMRS符号一致的传输功率;
当PUSCH含有两符号的DMRS且DMRS所在符号上有调度请求时,在第一个DMRS符号上有SR需求时,终端优先提供SR的功率,在第二个符号上DMRS保持和第一个符号上相同的功率;在第二个DMRS符号上SR需求时,终端优先保证DMRS的功率和第一个符号相同,其余的功率分配给SR传输;以上两种情况,SR采用的序列与DMRS采用序列不同或正交。
当PUSCH含有上行数据的符号上有调度请求时,为支持周期为X个符号的SR(X≥1),要在每X个符号上都预留资源,即在每X个符号上,预留至少一个资源单元(resource element,RE)承载SR,当没有SR时,预留资源的传输功率为0,当有SR时预留资源的传输功率不为0。具体而言,在每X个符号上都预留资源,有多种RE分配的方式。
方式一,在单一符号上分配PT-RS旁边的RE给SR。
具体的在PUSCH承载数据的符号上承载周期为X个符号的调度请求。在每X个符号上,预留一个资源承载SR,预留的资源包括一个或至少两个连续的RE。
可选的,在有PT-RS配置时,所述RE可位于与PT-RS相邻的RE上,如图13所示,X=1,每个符号上都为SR预留一个资源。
可选的,进一步为了提高传输的可靠性,可分配至少两个资源承载调度请求。一种方式如图14中的(a)所示,SR的周期X=1,每个符号上都为SR预留两个资源,每个资源包括一个或至少两个连续的RE,其中,承载调度请求的RE位于承载PT-RS的频域资源的两侧。或者如图14中的(b)所示,承载调度请求的RE可分别位于PT-RS的一侧和PUSCH所占频带一侧。
方式二:在单一符号上分配PUSCH所占频带两侧的RE给SR。
具体的,在PUSCH承载数据的符号上承载周期为X个符号的调度请求。在每X个符号上,预留一个或多个资源承载SR,预留的每个资源包括一个或至少两个连续的RE。在无PT-RS配置时,所述RE可位于PUSCH所占频带的一侧或两侧。
如图15中的(a)所示,SR的周期X=1,每个符号上都为SR预留两个资源,每个资源包括一个或至少两个连续的RE,其中,承载调度请求的RE位于PUSCH所占频带的两侧。如图15中的(b)所示,SR的周期X=1,每个符号上都为SR预留1个资源,每个资源包括一个或至少两个连续的RE,承载调度请求的REPUSCH所占频带的一侧。
方式三:在多个符号上分配RE给SR。
具体的,根据SR的周期,在PUSCH的多个符号上分配RE给SR,承载SR的RE在相邻的至少两个符号上位于不同的频域资源。单个符号上为SR预留的资源可以是一个, 也可以是两个。
可选的,假如SR的周期X=1或2,每个符号上都为SR预留资源,如图16中的(a)所示,相邻的两个符号上,在第一符号上承载调度请求的RE位于PT-RS的一侧,在第二符号上位于PT-RS的另一侧;如图16中的(b)所示,在第一符号上承载调度请求的RE位于PT-RS的一侧,在第二符号上位于PUSCH的一侧;如图16中的(c)所示,在第一符号上承载调度请求的RE位于PUSCH的一侧,在第二符号上位于PUSCH的一侧。相对于方式二,这种调度方式在较少RE资源的情况下,仍然达到了分集增益的效果。
针对仅承载调度请求的短时长PUCCH与其他信道出现时域资源重合的问题,本申请提供的第三种处理方案如下:
第三种处理方案为仅承载调度请求的短时长PUCCH与其他PUCCH共同传输或选择其一传输的处理方式。
情况一:仅承载SR的PUCCH与长时长PUCCH冲突时的处理方式。
此情况是仅承载调度请求的短时长PUCCH和长时长PUCCH同时出现,此处所述长时长PUCCH承载的信息可以是除了调度请求以外的信息,如ACK/NACK、信道质量指示(channel quality indicator,CQI)和CSI等,也可以是包括调度请求和其他信息,如ACK/NACK、CQI和CSI等,即长时长PUCCH不含仅承载调度请求的情况。
如图17所示,长时长PUCCH的一个时域符号和仅承载SR的短时长的PUCCH在时域上重合。长时长的PUCCH分为使用OCC进行多用户复用和不使用OCC两种,在使用OCC时,由于不同用户需要通过不同的码字去掉其他用户的干扰,所以各符号的功率要求不改变。
当长时长的PUCCH采用长度大于或等于2的OCC码扩容DMRS和UCI的符号时,仅承载SR的短时长的PUCCH的时域资源与长时长的PUCCH的起始符号或长时长的PUCCH任何一个跳频部分的起始符号相同时,终端同时传输长时长的PUCCH和仅承载SR的短时长的PUCCH,并优先分配功率给仅承载SR的短时长的PUCCH,剩余的功率(如有)分配给长时长的PUCCH使用;可选的,在仅承载SR的短时长的PUCCH传输结束后,在继续传输长时长的PUCCH时,长时长的PUCCH在当前时隙或跳频部分的功率,与同时传输时长时长的PUCCH的传输功率保持不变。
当长时长的PUCCH采用长度大于或等于2的OCC码扩容DMRS和UCI的符号时,所述仅承载SR的短时长的PUCCH的时域资源与长时长的PUCCH的其他符号位置相同时,终端在保证长时长的PUCCH功率不变的情况下,采用剩余的功率传输仅承载SR的短时长的PUCCH;
当长时长的PUCCH未配置OCC时,终端优先分配功率保证仅承载SR的短时长的PUCCH的传输,剩余功率分配给长时长的PUCCH;当终端的功率不能满足两者同时传输时,终端终止传输长时长的PUCCH,即两信道时域重合的部分只传输仅承载SR的短时长的PUCCH;在传输仅承载SR的短时长的PUCCH结束之后,终端可根据长时长的PUCCH剩余符号或已传输符号上是否既有DMRS符号又有UCI符号的情况决定是否继续传输,具体的,终端在某个频域资源上的长时长的PUCCH中剩余符号或已传输符号上既有DMRS符号也有UCI符号的情况下才继续传输,对于没有同频域资源下的DMRS符号和UCI符号的不传。
例如:当长时长的PUCCH未配置OCC时,两个信道时域重合部分只传输仅承载SR的短时长的PUCCH,仅承载SR的短时长的PUCCH停止之后,如长时长的PUCCH上已传输和剩余符号中有DMRS和UCI符号,可继续传输长时长的PUCCH。
例如:对于多时隙长时长的PUCCH的情况,两个信道时域重合部分只传输仅承载SR的短时长的PUCCH,仅承载SR的短时长的PUCCH结束之后,如有整个时隙未传输,可继续传输长时长的PUCCH。
情况二:仅承载SR的PUCCH与短时长的PUCCH冲突时的处理方式。
如图18所示,此种情况是仅承载调度请求的短时长的PUCCH和短时长的PUCCH同时出现,短时长的PUCCH承载的信息可以是除了调度请求以外的信息,如ACK/NACK、CSI和CQI等。短时长的PUCCH承载的信息也可以是包括调度请求和其他控制信息,如ACK/NACK、CSI和CQI等,即短时长的PUCCH不含仅承载调度请求的情况。其中,短时长的PUCCH可进一步分为单符号的、两符号联合编码的、两符号使能OCC三种。在这里,两符号使能OCC的短时长的PUCCH要单独分析,因为OCC用于多用户复用,如果因为同时传输而影响了其中一个符号的能量,则会造成多用户间干扰。
对于单符号的短时长的PUCCH或两符号的短时长的PUCCH采用跳频传输的情况(在跳频传输时由于频域资源不同,不会使用OCC):
1)若所述短时长的PUCCH仅承载CQI信息,功率优先保证仅承载SR的短时长的PUCCH,剩余的功率(如有)分给承载CQI的短时长的PUCCH,即SR的优先级高于CQI。
2)若所述短时长的PUCCH也同时承载SR和其他信息,终端根据两个信道分别承载的SR的优先级(服务类型、周期大小)等,把功率优先分配给高优先级的SR的信道,剩余功率(如有)分配给另外一种信道。
3)若所述短时长的PUCCH承载ACK/NACK(或者ACK/NACK和CSI),终端把功率平均分配给两种信道,或者终端根据ACK/NACK和SR的优先级,把功率优先分配给高优先级传输的信道,剩余功率(如有)分配给另外一种信道。
4)若所述短时长的PUCCH承载ACK/NACK(或者ACK/NACK和CSI),终端可根据ACK/NACK和SR(记为1bit)的信息量比值分配功率。
对于两符号的短时长的PUCCH使能OCC的情况:当两符号的短时长的PUCCH的第一符号上出现仅承载SR的短时长的PUCCH时,两种信道同时传输,根据上述四种情况分配功率,即功率优先分配给高优先级传输的信道,剩余功率(如有)分配给其他信道;当两符号的短时长的PUCCH的第二符号上出现仅承载SR的短时长的PUCCH时,两种信道同时传输,优先保证两符号的短时长的PUCCH的第二个符号和第一个符号的功率相同,额外功率分配给仅承载SR的短时长的PUCCH。
