Description

Uplink transmission method and corresponding equipment

Technical Field

The present invention relates to the field of mobile communication technologies, and in particular, to an uplink transmission method and a corresponding device.

Background

With the rapid development of the information industry, especially the growing demand from the mobile internet and internet of things (IoT), the future mobile communication technology is challenged with unprecedented challenges. Such as ITU-R M [ IMT. BEYOND 2020.TRAFFIC ] according to the International Telecommunications Union (ITU) report]As the mobile traffic is expected to increase nearly 1000 times in 2020 compared to 2010 (the 4G era), the number of UE connections will exceed 170 billion, and as a huge amount of IoT devices gradually penetrate into the mobile communication network, the number of connected devices will be more dramatic. To address this unprecedented challenge, the communications industry and academia have developed extensive fifth generation mobile communications technology (5G) research to target the 2020. ITU-R M, a report currently in ITU [ imt]The framework and overall objectives of the future 5G are discussed, wherein the requirements prospect, application scenario and various important performance indicators of the 5G are specified. For the new demand in 5G, ITU's report ITU-R M [ IMT]The method provides information related to the 5G technical trend, and aims to solve the remarkable problems of remarkable improvement of system throughput, user experience consistency and expansibility for supporting IoT, time delay, energy efficiency, cost, network flexibility, support of emerging services, flexible spectrum utilization and the like. In 3GPP (3)^rdGeneration Partnership Project, third Generation Partnership Project), the work on the first phase of 5G is already in progress. To support more flexible scheduling, the 3GPP decides to support variable Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) feedback delay in 5G. In an existing Long Term Evolution (LTE) system, an uplink transmission Time of receiving HARQ-ACK from downlink data is fixed, for example, in a Frequency Division Duplex (FDD) system, a Time delay is 4 subframes, and in a Time Division Duplex (TDD) system, an HARQ-ACK inverse is determined for a corresponding downlink subframe according to uplink and downlink configurationAnd feeding a time delay. In a 5G system, whether FDD or TDD, the uplink time unit for which HARQ-ACK can be fed back is variable for a certain downlink time unit (e.g., downlink timeslot or downlink mini-timeslot). For example, the HARQ-ACK feedback delay may be dynamically indicated through physical layer signaling, or different HARQ-ACK delays may be determined according to different services or user capabilities and other factors.

The 3GPP defines three major directions of a 5G application scenario, namely eMBB (enhanced mobile broadband), mtc (massive machine-type communication), URLLC (ultra-reliable and low-latency communication). The eMBB scene aims to further improve the data transmission rate on the basis of the existing mobile broadband service scene so as to improve the user experience, and thus the extremely communication experience between people is pursued. mMTC and URLLC are application scenarios of the Internet of things, but the respective emphasis points are different: mMTC is mainly information interaction between people and objects, and URLLC mainly embodies the communication requirements between the objects.

In 5G, the eMBB and the URLLC may adopt a joint networking mode, that is, both the URLLC service and the eMBB service are supported in the same cell. Because URLLC traffic may be sparse traffic, compared to URLLC single-network, eMBB and URLLC joint-network may improve system spectrum efficiency. When the system has the URLLC service, the URLLC service is preferentially scheduled, and when the system has no URLLC service or the resource occupied by the URLLC service is less, the eMBB service can be scheduled. At present, when the URLLC service and the eMBB service conflict, data and/or control information of the URLLC service may be preferentially transmitted, so that the performance of the eMBB service may be lost. Therefore, how to optimize transmission of data and control information of the eMBB service is an urgent problem to be solved.

Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

As used herein, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It will be understood by those within the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

As will be understood by those skilled in the art, a "terminal" as used herein includes both devices that include a wireless signal receiver, which are devices having only a wireless signal receiver without transmit capability, and receiving and transmitting hardware devices, which have receiving and transmitting hardware devices capable of two-way communication over a two-way communication link. Such a device may include: a cellular or other communication device having a single line display or a multi-line display or a cellular or other communication device without a multi-line display; a PCS (personal communications System), which may combine voice, data processing, facsimile and/or data communications capabilities; a PDA (personal digital assistant) which may include a radio frequency receiver, pager, internet/intranet access, web browser, notepad, calendar and/or GPS (global positioning system) receiver; a conventional laptop and/or palmtop computer or other device having and/or including a radio frequency receiver. As used herein, a "terminal" or "terminal device" may be portable, transportable, installed in a vehicle (aeronautical, maritime, and/or land-based), or situated and/or configured to operate locally and/or in a distributed fashion at any other location(s) on earth and/or in space. As used herein, a "terminal" and a "terminal device" may also be a communication terminal, a web terminal, and a music/video playing terminal, such as a PDA, an MID (mobile internet device) and/or a mobile phone with music/video playing function, and may also be a smart tv, a set-top box, and the like.

The 3GPP defines three major directions of a 5G application scenario, namely eMBB (mobile broadband enhancement), mtc (large-scale internet of things, more called mass machine type communication), URLLC (ultra-high reliable ultra-low latency communication). The eMBB scene is mainly used for pursuing the extremely consistent communication experience among people for further improving the performance of user experience and the like on the basis of the existing mobile broadband service scene. mMTC and URLLC are application scenarios of the Internet of things, but the respective emphasis points are different: mMTC is mainly information interaction between people and objects, and URLLC mainly embodies the communication requirements between the objects. The eMBBs and URLLC of the 5G adopt a joint networking mode to support both URLLC services and eMBBs in the same cell. Because URLLC traffic may be sparse traffic, compared with URLLC single-network, eMBB and URLLC joint-network may improve system spectrum efficiency. When the system has the URLLC service, the URLLC service is preferentially scheduled, and when the system has no URLLC service or the resource occupied by the URLLC service is less, the eMBB service can be scheduled. At present, when a URLLC service and an eMBB service conflict, data and/or control information of the URLLC service may be preferentially transmitted, at this time, the performance of the eMBB service may be lost, and how to optimize transmission of the data and control information of the eMBB service is urgent to solve.

Hereinafter, various embodiments of the present application will be described in detail with reference to the accompanying drawings.

In some embodiments, the first type of data may be data that is transmitted by the first type of transceiving node to the second type of transceiving node. In the following examples, the first type of data is exemplified by (but not limited to) Downlink data carried by a PDSCH (Physical Downlink Shared Channel).

In the following examples, the first type of control signaling is illustrated by taking downlink control signaling as an example (but not limited to). The Downlink Control signaling may be DCI (Downlink Control information) carried by a PDCCH (Physical Downlink Control Channel) and/or Control signaling carried by a PDSCH (Physical Downlink Shared Channel).

In some embodiments, the second type of control signaling may be control signaling sent by the second type of transceiving node to the first type of transceiving node. In the following examples, the second type of control signaling is illustrated by taking uplink control signaling as an example (but not limited to). The Uplink Control signaling may be UCI (Uplink Control Information) carried through a PUCCH (Physical Uplink Control Channel) and/or Control signaling carried through PUSCH (Physical Uplink Shared Channel).

The base station may provide wireless access according to one or more wireless communication protocols, e.g., 5G 3GPP New radio interface/Access (NR), Long Term Evolution (LTE), LTE-advanced (LTE-A), High Speed Packet Access (HSPA), Wi-Fi 802.11a/b/G/n/ac, etc. For convenience, the terms "BS" and "TRP" are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. Further, depending on the network type, the term "user equipment" or "UE" may refer to any component, such as a "mobile station," subscriber station, "" remote terminal, "" wireless terminal, "" reception point, "" user equipment, "or simply a" terminal. For convenience, the term "user equipment" or "UE" is used in this patent document to refer to a remote wireless device that wirelessly accesses a BS, whether the UE is a mobile device (such as a mobile phone or smartphone) or a commonly-considered stationary device (e.g., a desktop computer or vending machine).

Fig. 2 shows a flow diagram of a method performed by a UE according to one embodiment of the invention.

First, in step 201, the UE receives downlink data and/or downlink control signaling from a base station.

In step 202, the UE determines uplink data and/or uplink control signaling and an uplink time unit, an uplink physical channel and power for transmitting the second type of data and/or the second type of control signaling for transmitting the uplink data and/or the uplink control signaling based on the downlink data and/or the downlink control signaling.

In step 203, the UE transmits uplink data and/or uplink control signaling to the base station at the determined power for transmitting the second type of data and/or the second type of control signaling in the determined uplink time unit.

In some embodiments, the UE may be configured with two levels of priority for uplink transmissions. For example, the two levels of priority may include a first priority and a second priority that are different from each other. In one example, the first priority may be higher than the second priority. However, embodiments of the present disclosure are not limited thereto, e.g., the UE may be configured with more than two levels of priority. For convenience, in the embodiments of the present disclosure, the description is made in consideration that the first priority is higher than the second priority.

In one example, two levels of priority may be indicated by a priority number or priority index (e.g., priority index 1 and priority index 0). For example, a larger priority index may correspond to a higher priority, i.e., priority index 1 may correspond to a higher priority than priority index 0. In this case, a larger priority index (e.g., priority index 1) may be a higher priority (e.g., first priority) and a smaller priority index (e.g., priority index 0) may be a lower priority (e.g., second priority). However, embodiments of the present disclosure are not so limited, e.g., other priority indices or indicators may be used to indicate a two-level priority. For convenience, in the embodiment of the present disclosure, the description is made in consideration that a priority corresponding to a larger priority index (e.g., priority index 1) is higher than a priority corresponding to a smaller priority index (e.g., priority index 0). The present invention is not limited to the manner described above, for example, in an embodiment of the present disclosure, priority index 1 may be used interchangeably with first priority, a larger priority index, or a higher priority, and priority index 0 may be used interchangeably with second priority, a smaller priority index, or a lower priority.

In some embodiments, the two levels of priority with which the UE is configured may be two levels of physical layer priority. For example, one of two levels of priority (a first priority (e.g., priority index 1) or a second priority (e.g., priority index 0)) may be provided for PUSCH or PUCCH. In particular, one PUSCH or PUCCH transmission (including repeated transmission if any) may have (e.g., correspond to) a priority index of 0 or greater (e.g., priority index 1).

In one example, for scheduling-free PUSCH transmission, the UE may determine the priority index according to the parameter priority (if configured). For a PUCCH transmission with HARQ-ACK information corresponding to SPS (Semi-Persistent Scheduling) PDSCH reception or SPS PDSCH release, the UE may determine the priority index of the PUCCH transmission from the parameter HARQ-codebook id (if configured). The priority index of a certain PUSCH or PUCCH transmission of a UE may be 0 if the priority index is not configured for the PUSCH or PUCCH transmission.

In one example, if the UE monitors the PDCCH to detect DCI format 0_1 and DCI format 1_1, or DCI format 0_2 and DCI format 1_2 in the activated DL BWP, the priority index may be provided through the priority indication field. If the UE indicates the capability to listen to PDCCH in active DL BWP to detect DCI format 0_1 and DCI format 1_1, and to detect DCI format 0_2 and DCI format 1_2, DCI format 0_1 or DCI format 0_2 may schedule PUSCH transmission of any priority, and DCI format 1_1 or DCI format 1_2 may schedule PDSCH reception and trigger PUCCH transmission of corresponding HARQ-ACK information with any priority.

In one example, the UE may be configured with a PUCCH configuration list, which may contain two PUCCH configurations, including a first PUCCH configuration and a second PUCCH configuration. For example, the first PUCCH configuration may correspond to a second priority (e.g., a smaller priority index (e.g., priority index 0)), that is, the priority of the first PUCCH configuration may be the second priority (e.g., a smaller priority index (e.g., priority index 0)). Also, the second PUCCH configuration may correspond to the first priority (e.g., a larger priority index (e.g., priority index 1)), and the priority of the second PUCCH configuration may be the first priority (e.g., a larger priority index (e.g., priority index 1)).

For example, the sub-slot configuration length of each of the first PUCCH configuration and the second PUCCH configuration may be 7 OFDM symbols or 2 OFDM symbols. The sub-slot configuration lengths of different PUCCH configurations may be configured separately.

In some embodiments, the UE may be configured with a pdsch-HARQ-ACK-Codebook list. For example, the pdsch-HARQ-ACK-Codebook list may comprise two pdsch-HARQ-ACK-Codebook configurations, corresponding to the first HARQ-ACK Codebook and the second HARQ-ACK Codebook, respectively. For example, a first HARQ-ACK codebook is associated with a PUCCH of a smaller priority index (e.g., priority index 0) and a second HARQ-ACK codebook is associated with a PUCCH of a larger priority index (e.g., priority index 1). In this case, the priority of the first HARQ-ACK codebook may be a second priority (e.g., a smaller priority index (e.g., priority index 0)), and the priority of the second HARQ-ACK codebook may be a first priority (e.g., a larger priority index (e.g., priority index 1)).

In some embodiments, a first priority or higher priority (e.g., a larger priority index (e.g., priority index 1)) may correspond to first traffic (e.g., URLLC traffic) and a second priority or lower priority (e.g., a smaller priority index (e.g., priority index 0)) may correspond to second traffic (e.g., eMBB traffic).

According to an embodiment of the invention, UCIs with different priority indexes are multiplexed in the same PUCCH for transmission, and how to determine the transmission power of the PUCCH is a problem to be solved.

In this embodiment, the UCI of different priority indexes may adopt different code rates, or the UCI of different priority indexes may adopt the same code rate and uniform coding.

The method defines a power calculation method when the PUCCH comprises two parts of CSI, determines the power through the UCI with high priority, namely, the UCI without the CSI part 2, and can improve the reliability of the UCI with high priority for transmission. When the power is limited, a method for ensuring the reliability of the high-priority UCI is defined, and the reliability of the high-priority UCI transmission can be improved. Through parameter configuration, the scheduling flexibility can be increased, and the UCI with low priority can be sent as far as possible on the premise of ensuring the transmission reliability of the UCI with high priority.

According to an embodiment of the present invention, in case of single cell, dual uplink Carrier, or uplink CA (Carrier Aggregation), the sum of the powers calculated by the UE on each Carrier, uplink cell alone may exceed the total configured transmission power of the UE. At this time, the UE preferentially allocates the transmission with the high priority according to the transmission priority, and reduces the power of the transmission with the low priority, so as to ensure that the sum of the powers does not exceed the total configured transmission power. When UCI and/or data multiplexing of different priority indexes, how to order priorities of different channels is a problem to be solved.

In this embodiment, the rule for sorting the priorities of different channels is described by taking the priority index having 2 levels as an example, and this embodiment may also be used in a scenario where the priority index is more than 2.

The UE may be configured with one PUCCH configuration list, which may contain two PUCCH configurations. The priority of the first PUCCH configuration may be a smaller priority index (e.g., priority index 0). The priority of the second PUCCH configuration may be a larger priority index (e.g., priority index 1).

The power allocated by the UE to PUSCH/PUCCH/PRACH (Physical Random Access Channel)/SRS (Sounding Reference Signal) transmission is ordered from high to low in the following order to ensure that the total power is less than or equal to the maximum transmit power.

-PRACH transmission on the primary serving cell.

A PUSCH transmission containing HARQ-ACK information of a larger priority index (e.g. priority index 1), or a PUCCH transmission containing HARQ-ACK information of a larger priority index (e.g. priority index 1), and/or SR, and/or LRR. It should be noted that the PUSCH may be a PUSCH with a smaller priority index (e.g., priority index 0) or a PUSCH with a larger priority index (e.g., priority index 1), and the PUCCH may be a PUCCH with a smaller priority index (e.g., priority index 0) or a PUCCH with a larger priority index (e.g., priority index 1).

PUSCH transmission containing CSI of a larger priority index (e.g. priority index 1) or PUCCH transmission containing CSI of a larger priority index (e.g. priority index 1). It should be noted that the PUSCH may be a PUSCH with a smaller priority index (e.g., priority index 0) or a PUSCH with a larger priority index (e.g., priority index 1), and the PUCCH may be a PUCCH with a smaller priority index (e.g., priority index 0) or a PUCCH with a larger priority index (e.g., priority index 1).

HARQ-ACK information not containing a larger priority index (e.g. priority index 1) or PUSCH transmission of a larger priority index (e.g. priority index 1) of CSI. Optionally, the PUSCH may be further prioritized according to whether HARQ-ACK information or CSI of a smaller priority index (e.g., priority index 0) is included. For example, a PUSCH transmission containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI of a smaller priority index (e.g., priority index 0) may be prioritized over a PUSCH transmission containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI that does not contain a smaller priority index (e.g., priority index 0). Alternatively, a PUSCH transmission containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI of a smaller priority index (e.g., priority index 0) may be prioritized lower than a PUSCH transmission not containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI of a smaller priority index (e.g., priority index 0). Optionally, for the type-2 random access procedure, the PUSCH transmission of a larger priority index (e.g., priority index 1) on the primary serving cell is the same priority as a PUSCH transmission of a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK information of the larger priority index (e.g., priority index 1) or CSI. Alternatively, for a type-2 random access procedure, the PUSCH transmission with a larger priority index (e.g., priority index 1) on the primary serving cell is the same priority as a PUSCH transmission with a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK information or CSI for the larger priority index (e.g., priority index 1) and contains HARQ-ACK information and/or CSI for the smaller priority index (e.g., priority index 0). Alternatively, for a type-2 random access procedure, the PUSCH transmission of a larger priority index (e.g., priority index 1) on the primary serving cell is the same priority as the PUSCH transmission of a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK information or CSI for the larger priority index (e.g., priority index 1) and does not contain HARQ-ACK information and/or CSI for the smaller priority index (e.g., priority index 0).

PUSCH transmissions of smaller priority index (e.g. priority index 0) without HARQ-ACK information or CSI of larger priority index (e.g. priority index 1) and/or PUCCH transmissions of smaller priority index (e.g. priority index 0) without HARQ-ACK information or CSI or SR or LLR of larger priority index (e.g. priority index 1).

-PUCCH transmission of HARQ-ACK information containing a smaller priority index (e.g. priority index 0), and/or SR, and/or a smaller priority index of LRR (e.g. priority index 0), or PUSCH transmission of a smaller priority index of HARQ-ACK information containing a smaller priority index (e.g. priority index 0).

PUCCH transmission of a smaller priority index (e.g. priority index 0) containing CSI of a smaller priority index (e.g. priority index 0) and/or PUSCH transmission of a smaller priority index (e.g. priority index 0) containing CSI of a smaller priority index (e.g. priority index 0).

PUSCH transmissions with smaller priority index (e.g. priority index 0) without HARQ-ACK information or CSI of smaller priority index (e.g. priority index 0), PUSCH transmissions with smaller priority index (e.g. priority index 0) on the primary serving cell for type-2 random access procedures.

SRS transmission (aperiodic SRS with higher priority than semi-persistent and/or periodic SRS), or PRACH transmission on a serving cell outside the PCell.

It should be noted that, in the case of the same priority order, and for the operation of carrier aggregation, the UE preferentially considers the power allocation of transmission on the primary serving Cell of an MCG (Master Cell group) or an SCG (Secondary Cell group) rather than transmission on the Secondary serving Cell. With the same priority order, and for operation using two UL carriers, the UE preferentially allocates power for transmissions on the carrier in which the UE is configured to transmit PUCCH. If the PUCCH is not configured for either of the two UL carriers, the UE prioritizes the power allocation for transmissions on the non-supplemental UL carrier.

The method prescribes priority sequencing of power distribution of different channels when uplink power is controlled, and ensures the transmission power of the high-priority service preferentially, thereby improving the reliability of the high-priority service.

It should be noted that, in the embodiment of the present disclosure, the method for power control in which multiple UCIs of different priorities are multiplexed on one PUCCH is also applicable to a scenario in which the priority indexes of the multiple UCIs are the same but the types of the multiple UCIs are different from each other, and also applicable to a scenario in which the priority indexes of the multiple UCIs are different from each other and the types of the multiple UCIs are also different from each other.

It should be noted that, in the embodiment of the present disclosure, the method for power control in which multiple UCIs of different priorities are multiplexed onto one PUCCH may also be applied to multiplexing of UCI of Unicast (Unicast) and UCI of multicast (groupcast or multicast)/broadcast. For example, in the embodiments of the present disclosure, UCI with a larger priority index (e.g., HARQ-ACK) may be replaced with multicast/broadcast UCI, and in the embodiments of the present disclosure, UCI with a smaller priority index (e.g., HARQ-ACK) may be replaced with unicast UCI. Alternatively, the UCI (e.g., HARQ-ACK) with a smaller priority index in the embodiments of the present disclosure may be replaced with the UCI for multicast/broadcast, and the UCI (e.g., HARQ-ACK) with a larger priority index in the embodiments of the present disclosure may be replaced with the UCI for unicast.

In the embodiments of the present disclosure, unicast may refer to a manner in which a network communicates with one UE, and multicast/broadcast may refer to a manner in which a network communicates with a plurality of UEs. For example, the unicast PDSCH may be one PDSCH received by one UE, and scrambling of the PDSCH may be based on a Network Temporary identity value (RNTI) specific to the UE, such as a C-RNTI. The Multicast/Broadcast PDSCH may be one PDSCH received by more than one UE at the same time, and the scrambling of the PDSCH may be based on an RNTI common to the group of UEs, e.g., Multicast/Broadcast Services (MBS) -RNTI. The unicast UCI may include HARQ-ACK information, SR, or CSI for the unicast PDSCH. The multicast (groupcast or multicast)/broadcast UCI may include HARQ-ACK information of the multicast/broadcast PDSCH.

The UE does not support multiplexing UCI of larger priority index on PUCCH of smaller priority index for transmission.

The power allocation of the UE to PUSCH/PUCCH/PRACH (Physical Random Access Channel)/SRS (Sounding Reference Signal) transmission is ordered from high to low in the following order to ensure that the total power is less than or equal to the maximum transmission power.

-PRACH transmission on the primary serving cell.

It should be noted that the PUSCH may be a PUSCH with a smaller priority index (e.g., priority index 0) or a PUSCH with a larger priority index (e.g., priority index 1).

PUSCH transmission of CSI containing a larger priority index (e.g., priority index 1). It should be noted that the PUSCH may be a PUSCH with a smaller priority index (e.g., priority index 0) or a PUSCH with a larger priority index (e.g., priority index 1).

HARQ-ACK information not containing a larger priority index (e.g. priority index 1) or PUSCH transmission of a larger priority index (e.g. priority index 1) of CSI. Optionally, the PUSCH may be further prioritized according to whether HARQ-ACK information or CSI of a smaller priority index (e.g., priority index 0) is included. For example, a PUSCH transmission containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI of a smaller priority index (e.g., priority index 0) may be prioritized over a PUSCH transmission containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI that does not contain a smaller priority index (e.g., priority index 0). Alternatively, a PUSCH transmission containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI of a smaller priority index (e.g., priority index 0) may be prioritized lower than a PUSCH transmission not containing a larger priority index (e.g., priority index 1) for HARQ-ACK information and/or CSI of a smaller priority index (e.g., priority index 0). Optionally, for the type-2 random access procedure, the PUSCH of a larger priority index (e.g., priority index 1) on the primary serving cell is the same as the PUSCH priority of a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK information of the larger priority index (e.g., priority index 1) or CSI. Alternatively, for the type-2 random access procedure, the PUSCH of a larger priority index (e.g., priority index 1) on the primary serving cell is the same as the PUSCH priority of a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK information or CSI for the larger priority index (e.g., priority index 1) and contains HARQ-ACK information and/or CSI for the smaller priority index (e.g., priority index 0). Alternatively, for a type-2 random access procedure, the PUSCH of a larger priority index (e.g., priority index 1) on the primary serving cell is the same as the PUSCH priority of a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK information or CSI for the larger priority index (e.g., priority index 1) and does not contain HARQ-ACK information and/or CSI for the smaller priority index (e.g., priority index 0).

The method prescribes priority sequencing of power distribution of different channels when uplink power is controlled, and ensures the transmission power of the high-priority service preferentially, thereby improving the reliability of the high-priority service. According to an embodiment of the present invention, in case of single cell, dual uplink Carrier, or uplink CA (Carrier Aggregation), the sum of the powers calculated by the UE on each Carrier, uplink cell alone may exceed the total configured transmission power of the UE. At this time, the UE preferentially allocates the transmission with the high priority according to the transmission priority, and reduces the power of the transmission with the low priority, so as to ensure that the sum of the powers does not exceed the total configured transmission power. When UCI and/or data multiplexing of different priority indexes, how to order priorities of different channels is a problem to be solved.

The UE does not support multiplexing UCI and/or data of different priority indices.

-PRACH transmission on the primary serving cell.

PUSCH and/or PUCCH transmission of a larger priority index (e.g. priority index 1).

PUSCH and/or PUCCH transmission of smaller priority index (e.g. priority index 0).

-PUCCH and/or PUSCH transmission with same priority index

-PUCCH transmission containing HARQ-ACK information, and/or SR, and/or LRR, or PUSCH transmission containing HARQ-ACK information.

-PUCCH transmission containing CSI or PUSCH transmission containing CSI.

PUSCH transmission without HARQ-ACK information or CSI, and PUSCH transmission on the primary serving cell for type-2 random access procedure.

The method prescribes priority sequencing of power distribution of different channels when uplink power is controlled, and ensures the transmission power of the high-priority service preferentially, thereby improving the reliability of the high-priority service. The priority of the priority index channel is higher than that of the low priority index channel, the behavior of the UE is determined, and the reliability of uplink transmission is improved. For the uplink channels with the same priority, if the UE supports simultaneous transmission of the PUCCH/PUSCH, the method determines the priority sequence when the PUCCH and the PUSCH exist simultaneously, defines the behavior of the UE and improves the reliability of uplink transmission.

According to an embodiment of the present invention, when performing power allocation on the PUCCH and/or the PUSCH, at least one of the following rules may be followed to ensure that the total power is less than or equal to the maximum transmission power.

Rule one is as follows: a PUSCH transmission containing a larger priority index (e.g., priority index 1) of HARQ-ACK information of a larger priority index (e.g., priority index 1), or a PUCCH transmission containing a larger priority index (e.g., priority index 1), and/or SR, and/or a larger priority index (e.g., priority index 1) of LRR has a higher priority than other PUCCH/PUSCH transmissions excluding PRACH transmission on the primary serving cell.

Rule two: a PUSCH transmission containing HARQ-ACK information of a larger priority index (e.g., priority index 1), or a PUCCH transmission containing HARQ-ACK information of a larger priority index (e.g., priority index 1), and/or SR, and/or a larger priority index of LRR (e.g., priority index 1) has a higher priority than other PUCCH/PUSCH transmissions excluding PRACH transmission on the primary serving cell.

Rule three: a PUSCH transmission containing a larger priority index (e.g., priority index 1) for HARQ-ACK information of a larger priority index (e.g., priority index 1), or a HARQ-ACK information of a larger priority index (e.g., priority index 1), and/or an SR, and/or a PUCCH transmission of a larger priority index (e.g., priority index 1) of an LRR has a higher priority than a PUSCH transmission of a smaller priority index (e.g., priority index 0) for HARQ-ACK information of a larger priority index (e.g., priority index 1).

Rule four: the priority index of the PUSCH may be determined according to the priority index with the highest priority among data and control information in the PUSCH.

Rule five: the priority index of the PUCCH may be determined according to a priority index having the highest priority among control information in the PUCCH.

Rule six: a PUSCH transmission containing a larger priority index (e.g., priority index 1) for CSI is prioritized over (or below) a PUSCH transmission containing a smaller priority index (e.g., priority index 0) for HARQ-ACK information of the larger priority index (e.g., priority index 1).

Rule seven: a PUSCH transmission with a smaller priority index (e.g., priority index 0) for HARQ-ACK information containing a larger priority index (e.g., priority index 1) has a higher (or lower) priority than a PUSCH transmission with a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK or CSI.

For example, the power allocation by the UE to PUSCH/PUCCH/PRACH/SRS transmissions is ordered from high to low in the following order to ensure that the total power is less than or equal to the maximum transmit power:

-PRACH transmission on the primary serving cell.

PUSCH and/or PUCCH transmission and/or UCI transmission of a larger priority index (e.g. priority index 1). It should be noted that the priority index of the PUSCH may be determined according to the priority index with the highest priority in the data and control information in the PUSCH. For example, a PUSCH containing a smaller priority index (e.g., priority index 0) of HARQ-ACK information of a larger priority index (e.g., priority index 1) considers its priority index as a larger priority index. The priority index of the PUCCH may be determined according to a priority index having the highest priority among control information in the PUCCH.

Optionally PUSCH and/or PUCCH transmission of a smaller priority index (e.g. priority index 0).

-wherein for PUCCH and/or PUSCH transmissions with the same priority index, ordered from high to low in the following order:

-PUCCH transmission containing HARQ-ACK information, and/or SR, and/or LRR, and/or PUSCH transmission containing HARQ-ACK information.

Optionally, PUCCH transmissions containing HARQ-ACK information of higher priority index and/or PUSCH transmissions containing HARQ-ACK information of higher priority index are prioritized over PUSCH transmissions containing only HARQ-ACK information of lower priority index.

-PUCCH transmission containing CSI and/or PUSCH transmission containing CSI.

-SRS transmission (aperiodic SRS with higher priority than semi-persistent and/or periodic SRS), or PRACH transmission on serving cells other than the primary serving cell (PCell).

The method prescribes priority sequencing of power distribution of different channels when uplink power is controlled, and ensures the transmission power of the high-priority service preferentially, thereby improving the reliability of the high-priority service. The priority of the priority index channel is higher than that of the low priority index channel, the behavior of the UE is determined, and the reliability of uplink transmission is improved.
