Description

UPLINK MULTIPLEXING METHOD AND USER EQUIPMENT BACKGROUND OF DISCLOSURE

1. Field of Disclosure

The present disclosure relates to the field of communication systems operating in multiple-input multiple-output (MIMO) systems, and more particularly, to multiplexing overlapping uplink channels for a user equipment (UE) with multiple panels performing UL transmission simultaneously.

2. Description of Related Art

Wireless communication systems, such as the third-generation (3G) of mobile telephone standards and technology are well known. Such 3G standards and technology have been developed by the Third Generation Partnership Project (3GPP) . The 3rd generation of wireless communications has generally been developed to support macro-cell mobile phone communications. Communication systems and networks have developed towards being a broadband and mobile system. In cellular wireless communication systems, user equipment (UE) is connected by a wireless link to a radio access network (RAN) . The RAN comprises a set of base stations (BSs) that provide wireless links to the UEs located in cells covered by the base station, and an interface to a core network (CN) which provides overall network control. As will be appreciated the RAN and CN each conduct respective functions in relation to the overall network. The 3rd Generation Partnership Project has developed the so-called Long Term Evolution (LTE) system, namely, an Evolved Universal Mobile Telecommunication System Territorial Radio Access Network, (E-UTRAN) , for a mobile access network where one or more macro-cells are supported by a base station known as an eNodeB or eNB (evolved NodeB) . More recently, LTE is evolving further towards the so-called 5G or NR (new radio) systems where one or more cells are supported by a base station known as a gNB.

Technical Problem

MIMO is an effective approach to enhance the capacity of a radio link by multiplexing transmit and receive antennas. MIMO refers to a practical technique for sending and receiving more than one data signal simultaneously over the same radio channel, which greatly improves the performance of spectral efficiency.

MIMO is one of the key technologies in NR systems and has been successfully deployed and commercialized. In the communication system of MIMO, both UE and base station use a large number of antenna elements. Especially for UE, these antenna elements can be distributed in different panels, as shown in Figure 1. Each panel is placed at different positions on a UE to facilitate simultaneous communicate with different base stations.

In Rel-18 work item (WI) , a UE can perform multiple UL transmissions simultaneously under several limitations for simultaneous UL transmissions. The first limitation is that panels can only transmit either PUCCH+PUCCH or PUSCH+PUSCH simultaneously. The second limitation is that the total number of layers of PUSCH is not greater than 4. The third limitation is that the total number of codewords of PUSCH is not greater than 2. Simultaneous PUCCH transmissions mean that multiple PUCCH resources in the different panels of a UE overlaps in the time domain. According to the current multiplexing rule, these overlapping PUCCHs cannot transmit simultaneously even if they are allocated to the different panels. Obviously, the current multiplexing rule cannot support simultaneous PUCCH transmissions well. Therefore, the current multiplexing rule should be enhanced.

SUMMARY

An object of the present disclosure is to propose a user equipment and uplink multiplexing method.

In a first aspect, an embodiment of the invention provides an uplink multiplexing method for execution by a user equipment (UE) capable of multiple panels, comprising:

applying at least one of the following rules to one or more uplink transmissions of the UE:

In an embodiment, the uplink multiplexing method comprises:

intra-panel multiplexing one or more uplink transmissions associated with a first panel-specific Q set into first multiplexed information in a first uplink resource selected from the first panel-specific Q set when the first panel-specific Q set comprises multiple uplink transmissions allocated to be transmitted through a first panel of the UE;

intra-panel multiplexing one or more uplink transmissions associated with a second panel-specific Q set into second multiplexed information in a second uplink resource selected from the second panel-specific Q set when the second panel-specific Q set comprises multiple uplink transmissions allocated to be transmitted through a second panel of the UE;

transmitting the first multiplexed information in the first uplink resource through the first panel and the second multiplexed information in the second uplink resource through the second panel when the first uplink resource and the second uplink resource are two physical uplink control channel (PUCCH) resources or two physical uplink shared channel (PUSCH) resources and the UE does not apply inter-panel multiplexing to the first multiplexed information and the second multiplexed information.

The disclosed method may be programmed as a computer program product, that causes a computer to execute the disclosed method.

The disclosed method may be programmed as a computer program, that causes a computer to execute the disclosed method.

Advantageous Effects

Some embodiments of disclosure provide enhancement to current multiplexing rules. When a PUCCH resource allocated to a panel respectively overlaps with several PUSCH resources in the different panels, the UE does can determine with which PUSCH resource the information of the PUCCH should be multiplexed.

For a PUSCH allocated to a panel and PUCCHs allocated to one or more different panels, UCI carried by the PUCCHs is multiplexed with data carried by the PUSCH, and the panel associated with the PUSCH transmits the PUSCH that carries the partial or complete multiplexed UCI and data. Since UCI is not transmitted through an original panel corresponding to a TRP, this mechanism results in significant delay to multiple transmission/reception point (multi-TRP) with a non-idea backhaul. Some embodiments of the disclosure provides intra-panel multiplexing and PUCCH to PUSCH transformation to address the problem.

DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the disclosure are described in detail with the technical matters, structural features, achieved objects, and effects with reference to the accompanying drawings as follows. Specifically, the terminologies in the embodiments of the present disclosure are merely for describing the purpose of the certain embodiment, but not to limit the disclosure.

Embodiments of the disclosure provide methods for multiplexing overlapping uplink channels for a user equipment (UE) with multiple panels performing uplink (UL) transmission simultaneously. In Rel-15/16/17 of 3GPP standards, only one panel in a UE can perform a UL transmission on a carrier of a serving cell at the same time in spite of multiple panels a UE. When a UE has several PUCCH resources that overlaps in the time domain, all the overlapping PUCCH resources are located in one Q set which can be regarded as a UE-specific Q set. The UE can select one of the overlapping PUCCH resources and multiplex all uplink control information (UCI) carried by the overlapping PUCCH resources in the selected PUCCH resource. The panel of the UE only transmits the selected PUCCH carrying the partial or complete multiplexed UCI. When a PUCCH resource and a PUSCH have an overlapping region, UCI carried by the PUCCH is multiplexed with data carried by the PUSCH. The PUSCH carries the partial or complete multiplexed UCI and data. The panel of the UE only transmits the PUSCH that carries the partial or complete multiplexed UCI and data.

This invention is related to the wireless communication systems operating in multiple-input multiple-output (MIMO) systems. More specifically, the target is to provide some solutions to multiplexing behavior for overlapping UL channels for a UE with multiple panels performing UL transmission simultaneously.

The disclosure is to provide solutions to multiplex uplink (UL) channels overlapping in the time domain for a UE with multiple panels which performs UL transmission simultaneously. For overlapping PUCCHs, intra-panel multiplexing rules with panel-specific Q sets and inter-panel multiplexing rules with a UE-specific Q set are proposed. For overlapping PUCCHs and a PUSCH, intra-panel multiplexing rules and inter-panel multiplexing rules are proposed. In some embodiments, a PUCCH can be transformed to a PUSCH and transmitted in simultaneous PUSCH transmissions. These solutions not only make better use of the characteristics of simultaneous UL transmissions, but also reduce time delay and improve spectral efficiency.

For overlapping PUCCHs, intra-panel multiplexing rules with panel-specific Q sets and inter-panel multiplexing rules with a UE-specific Q set are proposed. For overlapping PUCCHs and a PUSCH, intra-panel multiplexing rules and inter-panel multiplexing rules are proposed. It is proposed that a PUCCH can be transformed to a PUSCH to be transmitted in simultaneous PUSCH transmissions. These solutions not only make better use of the characteristics of simultaneous UL transmissions, but also reduce time delay and improve spectral efficiency. In the embodiments, a UE, such as UE 10, performs resource allocation for UL transmission.

In the description, the term “resource” represents at least one time-frequency radio resource. In the description, a transmission of a channel, such as PUCCH or PUSCH, allocated to a panel means that the channel, such as PUCCH or PUSCH, is allocated to be transmitted through the allocated panel. The description in a way, such as reciting that two channel transmission overlap in one overlapping region, means that UL transmission (e.g., one of PUCCH or PUSCH) overlaps with another UL transmission (e.g., the other one of PUCCH or PUSCH) in one or more regions.

With reference to FIG. 2, for example, an embodiment of a UE 10 includes one of the UE 10a or UE 10b, an embodiment of a gNB 20 includes the

base station

In FIG. 2, the UE 10 and the gNB 20 execute an embodiment of an uplink multiplexing method. The UE performs an uplink multiplexing method to multiplex uplink signals (e.g., PUSCH and/or PUCCH) with respect to multiple panels (S001) . In some embodiments, the uplink multiplexing method may comprise intra-panel multiplexing. In some embodiments, the uplink multiplexing method may comprise inter-panel multiplexing. In some embodiments, the uplink multiplexing method may comprise transformation for uplink transmission. The UE 10 applies at least one of the following rules to one or more uplink transmissions of the UE:

an intra-panel multiplexing rule;

an inter-panel multiplexing rule; or

a transformation rule.

FIG. 3 shows an embodiment of the step S001. FIG. 4 shows another embodiment of the step S001.

For example, the UE intra-panel multiplexes one or more uplink transmissions associated with a first panel-specific Q set into first multiplexed information in a first uplink resource selected from the first panel-specific Q set when the first panel-specific Q set comprises multiple uplink transmissions allocated to be transmitted through a first panel of the UE.

The UE intra-panel multiplexes one or more uplink transmissions associated with a second panel-specific Q set into second multiplexed information in a second uplink resource selected from the second panel-specific Q set when the second panel-specific Q set comprises multiple uplink transmissions allocated to be transmitted through a second panel of the UE.

The UE transmits multiplexed signals (e.g., PUSCH and/or PUCCH) through the multiple panels (S003) . For example, the transmits the first multiplexed information in the first uplink resource through the first panel and the second multiplexed information in the second uplink resource through the second panel when the first uplink resource and the second uplink resource are two physical uplink control channel (PUCCH) resources or two physical uplink shared channel (PUSCH) resources and the UE does not apply inter-panel multiplexing to the first multiplexed information and the second multiplexed information.

The gNB receives the multiplexed signals (e.g., PUSCH and/or PUCCH) (S004) .

With reference to FIG. 3, for each panel to which intra-panel multiplexing is applicable, the UE intra-panel multiplexes one or more uplink transmissions in an uplink resource through the panel (S001a) .

With reference to FIG. 4, for each panel to which intra-panel multiplexing is applicable, the UE intra-panel multiplexes one or more uplink transmissions in an uplink resource through the panel (S0011) . For a two or more panels to which inter-panel multiplexing is applicable, the UE inter-panel multiplexes one or more uplink transmissions in one or more uplink resources through one of the panels (S0012) . For example, the UE inter-panel multiplexes the first multiplexed information and the second multiplexed information into inter-panel multiplex information when the UE applies inter-panel multiplexing to the first multiplexed information and the second multiplexed information. The UE transmits inter-panel multiplex information through one of the panels of the UE. The inter-panel multiplex information is transmitted in the second uplink resource when the first uplink resource carries the first multiplexed information is a PUCCH resource, and the second uplink resource carries the second multiplexed information is a PUSCH resource. The inter-panel multiplex information is transmitted in the first uplink resource when the first uplink resource carries the first multiplexed information is a PUSCH resource, and the second uplink resource carries the second multiplexed information is a PUCCH resource.

In an embodiment, the step S003 may further comprise a transformation operation for the multiplexed one or more uplink transmissions. When one or more uplink transmissions to be sent through the two or more panels cannot satisfy the limitations of simultaneous multi-panel uplink transmission (e.g., the multiplexed one or more uplink transmissions comprise simultaneous transmission of PUCCH+PUSCH or PUSCH+PUCCH) , the UE transforms PUCCH in the one or more uplink transmissions into PUSCH (S003a) .

For example, the UE transforms the first uplink resource into a PUSCH resource that is obtained by the UE from the first uplink resource when the first uplink resource is a PUCCH resource and the second uplink resource is a PUSCH resource.

The UE transforms the second uplink resource into a PUSCH resource that is obtained by the UE from the first uplink resource when the first uplink resource is a PUSCH resource and the second uplink resource is a PUCCH resource; and

The UE transmits the first multiplexed information in the first uplink resource through the first panel and the second multiplexed information in the second uplink resource through the second panel.

Embodiment 1

In the embodiment, one or more of intra-panel multiplexing rules and inter-panel multiplexing rules are proposed for simultaneous transmission of multiple PUCCHs through multiple panels of a UE. The type of multiplexing rule for PUCCHs can be semi-statically, semi-persistently, or dynamically indicated.

In an alternative embodiment, a UE uses an intra-panel multiplexing rule for multiplexing of PUCCHs with panel-specific Q sets. In the first step according to the rule, the UE recognize PUCCH resources that are allocated to a panel of a UE and have overlapping region (s) in the time domain. The PUCCH resources have overlapping region (s) in the time domain form overlapping PUCCH resources. The overlapping PUCCH resources form a panel-specific Q set. One PUCCH resource is selected by the UE from the Q set according to the number of bits of each PUCCH resource in the Q set. This selected PUCCH resource carries the partial or complete information that is originally carried by the PUCCH resources in the Q set. Each panel transmits one PUCCH selected from the panel-specific Q set.

Examples of uplink transmissions and multiplexing operations are shown in FIG. 6 to FIG. 23. The uplink transmissions in the figures are allocated with respect to time and frequency domains. A horizontal axis t represents the time domain, and a vertical axis f represents the frequency domain. The uplink transmissions in FIG. 7 to FIG. 23 are similar to FIG. 6 while the axes are not shown. For example, as shown in FIG. 6, a first PUCCH resource (i.e., PUCCH1) carrying first information and a second PUCCH resource (i.e., PUCCH2) carrying second information are allocated to the first panel of a UE, and a third PUCCH resource (i.e., PUCCH3) carrying the third information and a fourth PUCCH resource carrying the fourth information are allocated to the second panel. In the first panel, the first PUCCH resource (i.e., PUCCH1) and the second PUCCH resource (i.e., PUCCH2) have overlapping region (s) in the time domain. The first PUCCH resource (i.e., PUCCH1) and the second PUCCH resource (i.e., PUCCH2) are located in the first Q set corresponding to the first panel. According to the number of bits of the first PUCCH and the second PUCCH, the first PUCCH resource (i.e., PUCCH1) is selected from the first Q set to carry the partial or complete first information and the partial or complete second information. For the second panel, the third PUCCH resource (i.e., PUCCH3) and the fourth PUCCH resource have overlapping region (s) in the time domain. The third PUCCH resource (i.e., PUCCH3) and the fourth PUCCH resource are located in the second Q set corresponding to the second panel. According to the number of bits of the third PUCCH and the forth PUCCH, the third PUCCH resource (i.e., PUCCH3) is selected from the second Q set to carry the partial or complete third information and the partial or complete fourth information. The first panel of the UE transmits the first PUCCH, and the second panel transmits the third PUCCH, as shown in FIG. 7.

In an alternative embodiment, a UE follows an inter-panel multiplexing rule to multiplex and transmit PUCCHs within a UE-specific Q sets. In the first step according to the rule, the UE recognizes PUCCH resources across all panels of a UE have overlapping region (s) in the time domain. The overlapping PUCCH resources form a UE-specific Q set. One PUCCH resource is selected from the Q set according to the number of bits. This PUCCH resource carries the partial or complete information carried by the PUCCH resources in the Q set. A panel transmits the PUCCH which is selected from the UE-specific Q set.

For example, as shown in FIG. 8, the first PUCCH resource (i.e., PUCCH1) carrying the first information and the second PUCCH resource (i.e., PUCCH2) carrying the second information are allocated to the first panel of a UE and the third PUCCH resource (i.e., PUCCH3) carrying the third information and the fourth PUCCH resource carrying the fourth information are allocated to the second panel. Across two panels, all the PUCCH resources have overlapping region in the time domain. So all the PUCCH resources are located in the Q set. According to the number of bits, the first PUCCH resource (i.e., PUCCH1) is selected from the Q set to carry all the partial or complete information. The first panel of the UE transmits the first PUCCH, and the second panel does not transmit any signal, as shown in FIG. 9.

Embodiment 2

In this embodiment, it is proposed that an intra-panel multiplexing rule and an inter-panel multiplexing rule for PUCCHs and a PUSCH for a UE with multiple panels performing UL transmissions simultaneously. The type of multiplexing rule for PUCCHs and a PUSCH can be semi-statically, semi-persistently, or dynamically indicated.

In an alternative embodiment, it is proposed that an intra-panel multiplexing rule for PUCCHs and a PUSCH. In the first step according to the rule, the UE recognize a PUSCH resource and PUCCH resources which are allocated to the same panel and have overlapping region (s) in the time domain. In each panel, the partial or complete information carried by the PUCCH resource is multiplexed with the information carried by the PUSCH resource. Each panel of the UE transmits the PUSCH that carries the partial or complete multiplexed information.

For example, as shown in FIG. 10 the first PUSCH resource (i.e., PUSCH1) carrying the first information and the second PUCCH resource (i.e., PUCCH2) carrying the second information are allocated to the first panel of a UE, and the third PUCCH resource (i.e., PUCCH3) carrying the third information and the fourth PUSCH that carries the fourth information are allocated to the second panel. For the first panel, the first PUSCH resource (i.e., PUSCH1) and the second PUCCH resource (i.e., PUCCH2) have an overlapping region in the time domain. When the UE uses the rule, the partial or complete second information carried by the second PUCCH is multiplexed with the first information carried by the first PUSCH. This multiplexed information corresponding to the first panel is referred to as first multiplexed information. For the second panel, the third PUCCH resource (i.e., PUCCH3) and the fourth PUSCH resource (i.e., PUSCH4) have an overlapping region in the time domain. When the UE uses the rule, the partial or complete third information carried by the third PUCCH is multiplexed in the fourth information carried by the fourth PUSCH. This multiplexed information corresponding to the second panel is referred to as second multiplexed information. The first panel of the UE transmits the first PUSCH that carries the partial or complete first multiplexed information and the second panel transmits the fourth PUSCH that carries the partial or complete second multiplexed information, as shown in FIG. 11. The first PUSCH and the fourth PUSCH can partly or completely overlap in the time domain. If the first PUSCH and the fourth PUSCH completely overlap, the transmission scheme of the first PUSCH and the fourth PUSCH can be space division multiplexing (SDM) , single frequency network (SFN) , or frequency division multiplexing (FDM) . The transmission of the second PUCCH and the third PUCCH can partly or completely overlap in the time domain. If the second PUCCH and the third PUCCH completely overlap, the transmission scheme of the second PUCCH and the third PUCCH can be SFN or FDM.

In an alternative embodiment, the UE applies an inter-panel multiplexing rule to transmit PUCCHs and a PUSCH. In the first step according to the rule, the UE recognizes that a PUCCH resource allocated to a panel and PUSCH resources allocated to another panel have an overlapping region in the time domain. The partial or complete information carried by the PUCCH allocated to a panel resource is multiplexed with the information carried by the PUSCH resource allocated to another panel. One panel of the UE transmits the PUSCH that carries the partial or complete multiplexed information and another panel does not transmit any signal.

For example, as shown in FIG. 12, a first PUSCH resource (i.e., PUSCH1) carrying the first information is allocated to the first panel of a UE, and a second PUCCH resource (i.e., PUCCH2) carrying the second information is allocated to the second panel. The first PUSCH resource (i.e., PUSCH1) and the second PUCCH resource (i.e., PUCCH2) have an overlapping region in the time domain. When the UE uses the rule, the partial or complete second information carried by the second PUCCH is multiplexed with the first information and carried by the first PUSCH. The first panel of the UE transmits the first PUSCH that carries the partial or complete multiplexed information, and the second panel does not transmit any signal, as shown in FIG. 13.

For example, as shown in FIG. 14, the first PUSCH resource (i.e., PUSCH1) carrying the first information and the second PUCCH resource (i.e., PUCCH2) carrying the second information is allocated to the first panel of a UE. The third PUSCH resource (i.e., PUSCH3) carrying the third information is allocated to the second panel. For the first panel, the first PUSCH resource (i.e., PUSCH1) and the second PUCCH resource (i.e., PUCCH2) have an overlapping region in the time domain. For the two panels, the second PUCCH resource (i.e., PUCCH2) and the third PUSCH resource (i.e., PUSCH3) have an overlapping region in the time domain. In this case, the UE can be indicated whether to use for PUCCHs and a PUSCH, an intra-panel rule, an inter-panel rule, or both of the rules. On the other hand, the UE can select which rule to use according to the channel conditions or capabilities of UE. When the intra-panel rule is used, the partial or complete second information carried by the second PUCCH is multiplexed with the first information carried by the first PUSCH. This multiplexed information corresponding to the first panel is referred to as the first multiplexed information. The first panel of the UE transmits the first PUSCH that carries the partial or complete first multiplexed information, and the second panel of the UE transmits the third PUSCH that carries the third information, as shown in FIG. 15. When the inter-panel rule for PUCCHs and a PUSCH is used, the partial or complete second information carried by the second PUCCH is multiplexed with the third information and carried by the third PUSCH. This multiplexed information corresponding to the second panel is referred to as the second multiplexed information. The first panel of the UE transmits the first PUSCH that carries the first information, and the second panel transmits the third PUSCH that carries the partial or complete second multiplexed information, as shown in FIG. 15. When both of the two rules are used, a portion of the second information carried by the second PUCCH is multiplexed with the first information and carried by the first PUSCH. This multiplexed information corresponding to the first panel forms the first multiplexed information. A portion of the second information carried by the second PUCCH is multiplexed with the third information and carried by the third PUSCH. This multiplexed information corresponding to the second panel forms the second multiplexed information. The first panel of the UE transmits the first PUSCH that carries the partial or complete first multiplexed information, and the second panel of the UE transmits the third PUSCH that carries the partial or complete second multiplexed information, as shown in FIG. 15. The first PUSCH and the third PUSCH can partly or completely overlap in the time domain. If fully overlapping, the transmission scheme of the first PUSCH and the third PUSCH can be SDM, SFN, or FDM.

Embodiment 3

In this embodiment, the UE transforms a PUCCH into a PUSCH for transmission through multiple panels to realize simultaneous UL transmissions. In this embodiment, if a PUCCH resource allocated to a panel and a PUSCH resource allocated to another panel have an overlapping region in the time domain, the UE follows a rule for UL channel conversion to transform the PUCCH into a PUSCH with the same frequency and time resources in the same panel. The rule for UL channel conversion is referred to as transformation rule. The panel transmits the transformed PUSCH, and the other panel transmits the original PUSCH. If there are several overlapping PUCCH resources allocated to a panel, the UE performs intra-panel multiplexing to multiplex these PUCCH resources into a selected PUCCH, and the selected PUCCH is transformed into a PUSCH in the panel. If several non-overlapping PUCCH resources are allocated to a panel, the UE transforms these PUCCHs into non-overlapping PUSCHs for transmission through the panel.

For example, as shown in FIG. 16, the first PUSCH resource (i.e., PUSCH1) carrying the first information is allocated to the first panel of a UE, and the second PUCCH resource (i.e., PUCCH2) carrying the second information is allocated to the second panel of a UE. The first PUSCH resource (i.e., PUSCH1) and the second PUCCH resource (i.e., PUCCH2) have an overlapping region in the time domain. When the UE uses the rule for UL channel conversion, the UE transforms the second PUCCH into a second PUSCH whose frequency and time resources are the same as the second PUCCH. The first panel of the UE transmits the first PUSCH that carries the first information, and the second panel of the UE transmits the second PUSCH that carries the second information, as shown in FIG. 17.

For example, as shown in FIG. 18, the first PUSCH resource (i.e., PUSCH1) carrying the first information is allocated to the first panel of a UE. The second PUCCH resource (i.e., PUCCH2) carrying the second information and the third PUCCH resource (i.e., PUCCH3) carrying the third information are allocated to the second panel. Because the second PUCCH and the third PUCCH have an overlapping region in the time domain, the UE uses intra-panel multiplexing for PUCCHs first and multiplexes the second information carried by the second PUCCH and the third information carried by the third PUCCH into first multiplexed information. The second PUCCH resource (i.e., PUCCH2) is selected to carry the first multiplexed information including the partial and complete second and third information. If the second PUCCH resource (i.e., PUCCH2) and the first PUSCH resource (i.e., PUSCH1) have an overlapping region in the time domain, the UE transforms the second PUCCH into a second PUSCH whose frequency and time resources are the same as the second PUCCH. The first panel of the UE transmits the first PUSCH that carries the first information, and the second panel transmits the second PUSCH that carries the first multiplexed information, as shown in FIG. 19.

For example, as shown in FIG. 20, the first PUSCH resource (i.e., PUSCH1) carrying the first information is allocated to the first panel of a UE, and the second PUCCH resource (i.e., PUCCH2) carrying the second information and the third PUCCH resource (i.e., PUCCH3) carrying the third information are allocated to the second panel of the UE. Because the second PUCCH resource (i.e., PUCCH2) and the third PUCCH resource (i.e., PUCCH3) do not have an overlapping region in the time domain, intra-panel multiplexing for PUCCHs is not needed. The first PUSCH resource (i.e., PUSCH1) overlaps with the second PUCCH resource (i.e., PUCCH2) and the third PUCCH resource (i.e., PUCCH3) in the time domain. Thus, the UE transforms the second PUCCH and the third PUCCH to the second PUSCH and the third PUSCH whose frequency and time resources are the same as the second PUCCH and the third PUSCH. The first panel of the UE transmits the first PUSCH that carries the first information, and the second panel of the UE transmits the second PUSCH and the third PUSCH respectively carrying the second information and the third information, as shown in FIG. 21.

For example, as shown in FIG. 22, the first PUSCH resource (i.e., PUSCH1) carrying the first information and the second PUCCH resource (i.e., PUCCH2) carrying the second information are allocated to the first panel of a UE, and the third PUCCH resource (i.e., PUCCH3) carrying the third information are allocated to the second panel of the UE. Because the first PUSCH and the second PUCCH have an overlapping region in the time domain, the partial or complete second information carried by the second PUCCH is multiplexed with the first information and carried by the first PUSCH. The third PUCCH is transformed to the third PUSCH whose frequency and time resources are the same as the second PUCCH. The first panel of the UE transmits the first PUSCH that carries the partial or complete multiplexed information, and the second panel transmits the third PUSCH that carries the third information, as shown in FIG. 23. The second PUCCH and the third PUCCH can partly or completely overlap in the time domain. If fully overlapping, the transmission scheme of the second PUCCH and the third PUCCH can be SFN, or FDM.

Embodiment 4

The characteristics of a PUCCH is different from those of a PUSCH so that after a PUCCH is transformed to a PUSCH, the parameters of the PUSCH obtained from the PUCCH should be defined. In this embodiment, several methods are proposed for a UE to determine the transmission parameters of the PUSCH transformed from the PUCCH.

● The first conversion method is to predefine the transmission parameters of the PUSCH. The transmission parameters of the PUSCH resource obtained from the transforming are predefined by the UE or the base station.

● The second conversion method is to predefine a calculation method for calculating the transmission parameters of the PUSCH. The transmission parameters of the PUSCH resource obtained from the transforming are calculated by the UE or the base station according to a predefined calculation method.

● The third conversion method reuse the transmission parameters of configured grant (CG) PUSCH transmission as the transmission parameters of the PUSCH. The transmission parameters of the PUSCH resource obtained from the transforming are the same as transmission parameters of configured grant PUSCH transmission (i.e., a CG PUSCH) .

● The fourth conversion method is to determine the transmission parameters of the PUSCH based on the last PUSCH transmission. The transmission parameters of the PUSCH resource obtained from the transforming are the same as transmission parameters of a last PUSCH transmission (i.e., a last transmitted PUSCH) . The last PUSCH transmission may be a PUSCH transmission of the UE before the transforming.

The transmission parameters of the PUSCH resource obtained from the transforming are dynamically indicated or semi-statically indicated by higher layer signal, such as radio resource control (RRC) signaling n the first conversion method and the second conversion method, the base station may determine the transmission parameters of the PUSCH and dynamically indicates the determined transmission parameters to the UE. In the first conversion method and the second conversion method, the transmission parameters of the PUSCH may be semi-statically indicated by signaling in one of the higher layers, such as a signal in the radio resource control (RRC) layer.

In an alternative embodiment, two power conversion methods are proposed to determine power parameters of the PUSCH transformed from the PUCCH. The first power conversion method is to calculate the transmission power of the PUSCH transformed from the PUCCH based on the transmission power of the PUCCH the PUSCH resource is obtained according to at least one or more of the following parameters:

● A target power (P0) of the PUCCH;

● A number of resource blocks (RBs) of the PUCCH;

● A path loss of the PUCCH; and

● A closed loop index of the PUCCH.

The power second conversion method is to calculate the transmission power of the PUSCH transformed from the PUCCH based on the transmission power of a reference PUSCH in the third and fourth conversion method according to at least one or more of the following parameters:

● A target power (P0) of the reference PUSCH;

● A number of resource blocks (RBs) of the reference PUSCH;

● A path loss compensation factor (Alpha) of the reference PUSCH;

● A path loss of the reference PUSCH; and

● A closed loop index of the reference PUSCH.

The reference PUSCH can be the last transmitted PUSCH.

In an alternative embodiment, for the PUSCH resource obtained from the transforming, if transmission parameters of the PUSCH resource are predefined, a transmission layer of the PUSCH resource is set to 1, a transmission port of a panel that transmits the PUSCH resource obtained from the transforming is set to 0, and a demodulation reference signal (DMRS) pattern utilizes 1 symbol and type 1 without additional DMRS.

If the calculation method is predefined, for the PUSCH resource obtained from the transforming, a transmission layer is 1, a transmission port of a panel that transmits the PUSCH resource obtained from the transforming is different from that of another panel, and the UE determines a demodulation reference signal (DMRS) pattern for the PUSCH resource obtained from the transforming according to a number of bits of uplink control information (UCI) carried by the PUCCH from which the PUSCH resource is obtained.

In an alternative embodiment, if the transmission parameters of the PUSCH resource obtained from the transforming are predefined, for the PUSCH resource obtained from the transforming, a modulation order is set to quadrature phase shift keying (QPSK) , and a code rate is set to 340/1024.

If the calculation method is predefined, for the PUSCH resource obtained from the transforming, the UE determines the modulation order and the code rate according to a number of bits of uplink control information (UCI) carried by the PUCCH from which the PUSCH resource is obtained.

In an alternative embodiment, the redundancy version for transmission of the PUSCH is always set to 0.

Embodiment 5

For single TRP or multi-TRPs with an idea backhaul, a TRP can know the scheduling conditions of other TRPs. Therefore, when a transmission/reception point (TRP) receives from the UE an uplink transmission with multiplexed information (e.g., the multiplexed information in the aforementioned embodiments) of which time and frequency resources are located in a PUCCH resource, if the PUCCH is transformed to PUSCH, the TRP utilizes a PUSCH decoding procedure to decode the multiplexed information.

For multi-TRPs with non-idea backhaul, a TRP cannot know the scheduling conditions of the other TRPs. Therefore, when a TRP receives from the UE an uplink transmission with multiplexed information (e.g., the multiplexed information in the aforementioned embodiments) of which time and frequency resources are located in a PUCCH resource, if the PUCCH is transformed to PUSCH, the TRP first utilizes a PUCCH decoding procedure to decode the multiplexed information and then utilizes the PUSCH decoding procedure to decode the multiplexed information.
