Detailed Description

The present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the present application can be applied to the existing cellular communication systems, such as global system for mobile communication (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), and other systems. Meanwhile, the method is also suitable for future wireless communication systems, and is suitable for 5G (fifth generation mobile communication systems) systems, such as an access network adopting NR; communication systems such as Cloud Radio Access Network (CRAN) may also be extended to similar wIreless communication systems, such as wIreless fidelity (wifi), Worldwide Interoperability for Microwave Access (WiMAX), and 3 gpp-related cellular systems.

As shown in fig. 1, which is a schematic view of an application scenario applicable to the present application, a network architecture and a service scenario described in the embodiment of the present invention are for more clearly explaining the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention.

Fig. 1 shows a schematic diagram of one possible application scenario of the present invention, which includes at least one terminal 10 communicating with a Radio Access Network (RAN). The RAN comprises at least one base station 20 (BS), of which only one base station and one UE are shown for clarity. The RAN is connected to a Core Network (CN). Optionally, the CN may be coupled to one or more external networks (external networks), such as the internet, Public Switched Telephone Network (PSTN), and the like.

Some of the terms referred to in this application are described below for the sake of clarity.

1) A communication device, also known as a terminal, a User Equipment (UE), or a device providing voice and/or data connectivity to a User, such as a handheld device with wireless connectivity, a vehicle-mounted device, etc. Common terminals include, for example: the mobile phone includes a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), and a wearable device such as a smart watch, a smart bracelet, a pedometer, and the like. The communication device may be implemented by a chip. Hereinafter, for convenience of description, the communication devices are collectively referred to as a terminal.

2) A Network device, such as a base station, which is also called a Radio Access Network (RAN) device, is a device for accessing a terminal to a wireless Network, and includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home evolved Node B or Home Node B, abbreviated as HNB), Base Band Unit (BBU), Base Station (g NodeB, gNB), transmission point (TRP), Transmission Point (TP). In addition, a Wifi Access Point (AP) or the like may also be included. Hereinafter, for convenience of description, network devices are collectively referred to as a base station.

Embodiments provided herein are applicable to a Carrier aggregation scenario, so-called Carrier aggregation, in which two or more Component Carriers (CCs) are aggregated together to support a larger transmission bandwidth. The component carrier may also be referred to as a carrier. For example, at least one carrier may be included in one cell. For a Cell in carrier aggregation, a Primary serving Cell (PCell) and a Secondary serving Cell (SCell) may be included. Specifically, the Pcell may be a cell in which the terminal communicates with the base station when initial connection is established, or a cell in which RRC connection or reconfiguration is performed, or a cell determined by the base station or the terminal in a handover process, and is mainly used for implementing RRC communication between the base station and the terminal. The Scell may be a cell in which the base station newly adds to provide service for the terminal when the RRC reconfiguration is performed, for example, RRC communication may not be implemented between the Scell and the terminal.

In the case of the 5G system, for example, there may be different frame structure types. For example, one frame structure type in which one radio frame includes ten subframes and one subframe includes two slots. One slot consists of 7 symbols. Alternatively, one subframe may include 14 symbols. Slots in one radio frame are numbered #0 to # 19. One subframe includes a normal subframe and a special subframe, wherein the normal subframe includes an uplink subframe and a downlink subframe. For example, an uplink subframe is generally divided into a control region and a data region on resources, a PUCCH for transmitting uplink control information is allocated to the control region, and a PUSCH for transmitting data is allocated to the data region.

In a CA scenario, one PUCCH group may include at least one carrier, where the carrier in one PUCCH group allows cross-carrier scheduling and cross-carrier feedback, that is, a certain carrier may send control information of some other carriers, and a certain carrier may carry uplink control information on other carriers, including ACK information and CSI information. In terms of UCI, the terminal may transmit UCI to the base station through PUCCH or PUSCH. When UCI is transmitted on a PUCCH within a PUCCH group, it may be understood that UCI is transmitted on a carrier corresponding to the PUCCH group. When the terminal sends UCI on the PUSCH, UC is generally multiplexed with uplink data and transmitted to the base station. Specifically, when both PUCCH and PUSCH can be simultaneously used for transmitting UCI, the terminal generally transmits UCI on the PUCCH and uplink data on the PUSCH. When PUCCH and PUSCH cannot be used for transmitting UCI simultaneously, the terminal generally transmits on PUSCH, and this transmission mode is also referred to as UCI channel assignment transmission, for example, the UCI channel assignment is performed to PUSCH corresponding to an uplink carrier with a minimum SCell Index value (SCell Index).

For a 5G New Radio (NR) with simultaneous transmission of low frequency and high frequency, it needs to support more services and richer spectrum resources. The spectrum resource of the high frequency band has larger bandwidth, and is an effective way for realizing the communication with large number rate. In addition, NR needs to support more scenarios, such as a CA scenario supporting a stand alone UL CC (SUL CC). The reason for supporting this carrier type is on one hand that the transmission power of the terminal is considered, because the uplink and downlink coverage are usually not balanced, and the uplink coverage is weaker than the downlink coverage. Meanwhile, with the introduction of a high frequency band, downlink transmission supports massive MIMO (large-scale antenna technology), and the phenomenon of unbalanced uplink and downlink coverage is more obvious. Furthermore, NR may correspond to multiple PUSCHs for one PUCCH with respect to the same time domain resource. In addition, flexible uplink scheduling and feedback timing are supported in the 5G NR, and the robustness of 5G system transmission needs to be considered.

Therefore, fig. 2a exemplarily shows a flow of uplink control information transmission provided by the present application.

Step 101, a communication device receives uplink scheduling information sent by a network device, wherein the uplink scheduling information is used for scheduling a first PUSCH corresponding to a first time domain resource, and the communication device receives indication information sent by the network device, and the indication information is used for indicating the communication device to transmit a second time domain resource of uplink control information UCI;

and step 102, when the communication device determines that the first time domain resource and the second time domain resource are overlapped according to the uplink scheduling information and the indication information, determining a second PUSCH for transmitting the UCI from the first PUSCH according to a third time domain resource corresponding to the uplink scheduling information.

Step 103, the communication device sends the UCI to the network device on the second PUSCH.

In an embodiment of the present invention, the uplink control information may be uplink scheduling (UL grant). For example, the UL Grant may be transmitted from the base station to the terminal through a Physical Downlink Control Channel (PDCCH). For convenience of description, the uplink control information is hereinafter collectively referred to as a UL grant. Specifically, the UL Grant is used to indicate the first PUSCH which is the allocation result of the uplink resource, and the base station may notify the communication device of the uplink resource through the UL Grant transmitted on the PDCCH, for example, the UL Grant indicates on which PUSCH the communication device may transmit the uplink data.

In the embodiment of the present invention, the time domain resource indicated by the indication information may be a time unit in which a certain PUCCH resource is located. The time unit is used to indicate a time unit in the time domain, and may be, for example, a sampling point, a symbol, a micro slot, a subframe, or a radio frame. The time domain resource or time unit information may include a type, a length, or a structure of a time unit, etc.

For example, the first time domain resource indicated by the indication information is a subframe or a slot in which the PUCCH is located. Assuming that the length of the subframe where the PUCCH is located is 1ms, the first time domain resource is the subframe. Or assuming that the PUCCH resource occupies the last two symbols in a 14-symbol subframe, the first time domain resource is the last two symbols occupied by the PUCCH resource or the first time domain resource is the two symbols occupied by the PUCCH resource plus an additional time length, which may be a processing time defined by a symbol or an absolute time.

It should be noted that both the indication information and the UL Grant may be carried in Downlink Control Information (DCI) of the PDCCH, and the network device transmits the DCI to the communication device through the PDCCH. Specifically, the indication information and the UL Grant may be carried in different DCIs or carried in the same DCI. For another example, the UL Grant is carried in the DCI of the PDCCH, and the indication information is notified to the communication device by the network device through other signaling, such as higher layer signaling, which is not specifically limited in this embodiment of the application.

In the embodiment of the present invention, for example, the communication device cannot transmit UCI based on PUSCH and PUCCH at the same time. Specifically, when multiple uplink resources such as PUSCHs are scheduled by multiple UL grants, and the first time domain resource and the second time domain resource overlap in time, the communication device needs to select a PUSCH for transmitting UCI from the allocated multiple PUSCHs. Several implementations are described in detail below.

According to the first implementation manner, the communication device determines a second PUSCH for transmitting the UCI according to the received time sequence of the plurality of uplink scheduling information. For example, the communication device may determine the second PUSCH for transmitting the UCI according to the receiving order of the multiple uplink scheduling information.

And the communication equipment determines a plurality of PUSCHs according to the time sequence of the uplink scheduling information. Specifically, if the communication device receives multiple UL grants at the same time at the earliest time of receiving the UL grant, the communication device may determine, according to the cell information corresponding to the PUSCH, the PUSCH for carrying the UCI in the channel associated transmission manner. Specifically, the cell information may include a cell type of the cell and an index of a secondary cell if the cell is the secondary cell; or cell numerology, etc. If the PUSCH scheduled by the UL Grant exists on the PCell currently accessed by the terminal, the PUSCH on the PCell is selected to transmit UCI along with the channel; otherwise, the terminal selects the PUSCH scheduled by the UL Grant from the SCell with the smallest index value (i.e., scellndex is smallest) to transmit UCI with the channel.

In the embodiment of the present invention, Numerology is a parameter adopted by the communication system. A communication system (e.g., 5G) may support multiple numerologies. numerology may be defined by one or more of the following parameter information: subcarrier spacing, Cyclic Prefix (CP), time unit, bandwidth, etc. For example, numerology may be defined by subcarrier spacing and CP. The subcarrier spacing may be 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz, etc. For example, the different subcarrier spacings may be integer multiples of 15 KHz. It will be appreciated that other values may be devised. The CP information may include a CP length and/or a CP type. For example, the CP may be a Normal CP (NCP) or an Extended CP (ECP).

For example, the terminal may select a PUSCH resource with a small subcarrier spacing to carry UCI; or, selecting a PUSCH carrying UCI having the same or close to the subcarrier spacing of the PUCCH. Here, close can be understood that the ratio of the PUSCH to PUCCH subcarrier spacing is close to 1.

In the third implementation manner, the communication device may determine, according to cell information corresponding to the PUSCH, a second PUSCH for transmitting the UCI. Specifically, the cell information may include a cell type of the cell and an index of a secondary cell if the cell is the secondary cell; or cell numerology, etc.

And the communication equipment determines a plurality of PUSCH resources according to the cell information. Specifically, when the communication device has multiple PUSCH resources overlapping with the first time domain resource in a certain cell, the communication device may determine the PUSCH for carrying the UCI in the channel associated transmission manner according to the time sequence of multiple uplink scheduling information corresponding to the multiple PUSCHs.

It should be noted that there may be one or more PUSCH resources selected to carry UCI in the associated transmission manner.

In the embodiment of the present application, the PUSCH for carrying the UCI selected by the communication device may be understood as one PUSCH, or may refer to multiple PUSCHs.

When the communication equipment selects a plurality of PUSCH resources to carry UCI information, the UCI information carried on each PUCCH resource is the same. Further, the content of UCI, the encoding method, and the mapping rule in the PUSCH may be the same. The robustness of the PUSCH can be enhanced by selecting multiple PUSCHs to transmit the same UCI, that is, when multiple UCIs jointly carry the PUSCH, each PUSCH carries the same UCI information completely (or as completely as possible). When the resource on one PUSCH is not used (for example, the uplink scheduling grant terminal device scheduling the PUSCH resource does not receive) or is not decoded correctly, UCI information can still be obtained through UCI carried on other PUSCH resources.

It should be noted that, in this embodiment of the present application, the network device may select at least one of the above four embodiments, and determine the second PUSCH from the first PUSCH, that is, the terminal device may simultaneously determine the second PUSCH from the first PUSCH based on parameters such as information of the third time domain resource, cell information, and the like, and a specific determination manner is selected according to actual needs, which is not limited in this embodiment of the present application.

Considering that when the communication device transmits UCI on the PUSCH along with the channel, it may affect the coding and mapping when uplink data is transmitted on the PUSCH, so in order to ensure that the PUSCH has enough time to process UCI, the second PUSCH selected by the communication device for transmitting UCI also needs the timing parameters indicated in the scheduling information and the indication information to satisfy a certain condition. The timing parameters may include the timing of the uplink scheduling grant to its scheduled uplink transmission second PUSCH, or the minimum of the timing of the uplink scheduling grant to its scheduled uplink transmission second PUSCH, which depends on the capability of the terminal user or the set of timings of the uplink scheduling grant configured by the base station to the terminal user to its scheduled uplink transmission second PUSCH, the timing of the downlink scheduling grant to its scheduled downlink transmission PDSCH to schedule downlink transmission, and the timing of the downlink transmission PDSCH to its uplink feedback UCI. For example, the second PUSCH further satisfies a first transmission condition, and the first transmission condition is determined according to the timing parameters in the uplink scheduling information and the indication information.

Since the content of UCI transmitted by the communication device may be different, for example, the UCI may include ACK or CSI, or both, the communication device needs to determine the second PUSCH for transmitting UCI according to the transmission content of the UCI.

Scenario one, when ACK is included and/or CSI is not included in UCI, k is indicated in DCI transmitted by a network device to a communication device₀And k is₂。k₁Indicating the timing of the DCI to the uplink transmission second PUSCH, or k1 may indicate the minimum value of DCI to the uplink transmission second PUSCH, which depends on the end user's capability or the set of k1 the base station configures to the end user, k₀For the timing of DCI to downlink PDSCH, k₂For the timing of the uplink UCI feedback of the transmitted PDSCH, if the second PUSCH satisfies the following formula [1]]In one, the second PUSCH has enough time to process UCI.

k₀×n₂+k₂×n₃≥k₁×n₄… … … … … … … … … … formula [1]

Wherein n is₂Time unit length, n, of PDCCH resource received for UE₃Is the length of a time unit on a PUCCH carrier, n₄Is a time unit length of the second PUSCH resource. The time unit can be the length of a subframe or the length of a symbol。

As shown in FIG. 3, k₀Is 2, k₁Is 2, k₂Is 4 because n₂、n₃Are all 0.5ms, n₄Is 1ms, so the formula [1] is satisfied]Therefore, the PUSCH satisfies the transmission condition, and can be used for channel-associated transmission of UCI because it has enough time to complete UCI processing.

As shown in FIG. 4, k₀Is 1, k₁Is 2, k₂Is 2 because n₂、n₃Are all 0.5ms, n₄Is 1ms, so equation [1] is not satisfied]Therefore, the PUSCH does not satisfy the transmission condition and cannot be used to transmit UCI.

In addition to the timing relationship condition defined in equation [1], there may be other equation definition ways in which the timing relationship satisfies the condition. The following are two other examples.

k₂×n₃≥k₁×n₄… … … … … … … … … … formula [2 ]]

k₀×n₂+k₂×n₃≥k₁×max(n₃,n₄) … … … … … … … … … … formula [3]

In scenario two, when the UCI includes CSI and/or does not include ACK, if the second PUSCH satisfies formula [4], the second PUSCH has enough time to process the UCI and may be used to transmit the UCI, otherwise, the second PUSCH cannot be used to transmit the UCI.

k×n₂≥k₁×n₄… … … … … … … … … … formula [4]]

K is the timing from the indication signaling triggering CSI to CSI transmission, the indication signaling can be DCI triggering aperiodic CSI feedback or higher layer signaling configuring periodic CSI feedback, k₁Timing feedback of the second PUSCH, n₂Is the length of a time unit on a PUCCH carrier, n₄And the length of the time unit corresponding to the second PUSCH resource. The time unit length may be a subframe length.

In a third scenario, when the UCI includes both ACK and CSI, if the second PUSCH satisfies one of the formulas [1] to [3] and formula 4, the second PUSCH has enough time to process the UCI and may be used to transmit the UCI, otherwise, the second PUSCH cannot be used to transmit the UCI. Or, only ACK satisfying any one of the formulas [1] to [3] and CSI satisfying the formula [4] are transmitted on the second PUSCH resource.

Optionally, in this embodiment of the present application, in a possible design, when the communication device determines that there are multiple PUSCHs scheduled first according to the time sequence of the uplink scheduling information, the multiple PUSCHs may be further sorted according to the subcarrier intervals of the PUSCH, that is, sorted according to the principle that the subcarrier intervals are from small to large. Thus, the communication device can preferentially select the PUSCH with the smaller subcarrier spacing as the PUSCH for transmitting UCI. For example, when the communication device transmits UCI, it is determined that PUSCH is scheduled on a carrier component with a subcarrier spacing of 15KHZ, and the communication device follows the UCI on the PUSCH; otherwise, when the PUSCH is scheduled on the carrier component with the subcarrier interval of 30KHZ, the communication equipment follows the UCI on the PUSCH.

In addition, in another embodiment of the present application, a communication device may group carriers. For example, carriers having subcarrier spacings of 15kHZ and 30kHZ are grouped into a first group and carriers having remaining subcarrier spacings are grouped into a second group. When UCI needs channel associated transmission and the first group of carrier waves have scheduled PUSCHs, the communication equipment transmits the UCI to the PUSCHs of the first group of carrier waves in a channel associated mode, otherwise, the communication equipment transmits the UCI to the PUSCHs of the second group of carrier waves in a channel associated mode. The PUSCH with a small subcarrier interval is preferably selected, because generally, PUSCH resources corresponding to the small subcarrier interval have better coverage.

Furthermore, in another embodiment of the present application, the communication devices may be grouped according to the frequency band of the carrier. For example, carriers having a frequency band of 6GHZ or less are grouped into a first group, and carriers having a frequency band of 6GHZ or more are grouped into a second group. When UCI is sent and PUSCH transmission exists on the first group of carriers, the UCI is transmitted along with the PUSCH of the first group of carriers, otherwise, the UCI is transmitted along with the PUSCH of the second group of carriers. The low-frequency PUSCH is preferably selected because the PUSCH resource coverage corresponding to the low-frequency is generally better.

Fig. 2b exemplarily shows a flow of uplink control information transmission provided by the present application.

Step 201, a network device sends uplink scheduling information and indication information to a communication device, wherein the uplink scheduling information is used for scheduling a first Physical Uplink Shared Channel (PUSCH), the first PUSCH corresponds to a first time domain resource, and the indication information indicates the communication device to transmit a second time domain resource of UCI;

step 202, when the first time domain resource and the second time domain resource are overlapped, the network device receives the UCI transmitted by the communication device on a second PUSCH, and the second PUSCH is determined by the communication device from the first PUSCH according to a third time domain resource corresponding to the uplink scheduling information.

In the embodiment of the present invention, for example, the communication device cannot transmit UCI based on PUSCH and PUCCH at the same time.

the transmitting unit 503 transmits the UCI to the network device on the second PUSCH.

In an embodiment, when the receiving unit 501 receives multiple pieces of uplink scheduling information, the processing unit 502 is specifically configured to: and determining a second PUSCH for transmitting the UCI according to the received time sequence of the plurality of uplink scheduling information. For example, according to the sequence of the receiving time, determining a second PUSCH for transmitting the UCI.
