Description

A method of transmitting channel state information of a terminal in a wireless communication system and a terminal

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wireless communication, and more particularly, to a method of transmitting channel state information of a terminal in a wireless communication system and a terminal using the method.

Recently, the 3GPP standardization group is considering a network slicing scheme for implementing a plurality of logical networks on a single physical network in an NR system as a 5G wireless communication system. The logical network must be able to support services with various requirements (eg, eMBB, mMTC, URLLC, etc.). In the physical layer system of the NR system, orthogonal frequency division (OFDM), which can have a variable numeric multiplexing scheme is considered. In other words, in the NR (New RAT) system, an OFDM scheme (or a multiple access scheme) having a mutually independent Numerology can be considered for each time and frequency resource region.

When the semi-persistent transmission of the CSI utilizing the PUSCH or PUCCH resources (i.e., the operation of transmitting the CSI at regular intervals during a predetermined time interval) is supported in the wireless communication system including the base station and the terminal, (PUCCH or PUSCH) transmitting a semi-persistent CSI and a different UL physical channel (eg, PUCCH or PUSCH). Also, when SP-CSI is transmitted as a PUCCH resource, a PUCCH resource allocation scheme for SP-CSI transmission is proposed.

The present invention provides a method for transmitting channel state information of a terminal and a terminal using the method in a wireless communication system.

According to an embodiment of the present invention, there is provided a method of transmitting a first PUSCH or a second PUSCH performed by a terminal in a wireless communication system, the method comprising: receiving control information; And transmitting the first PUSCH or the second PUSCH, wherein the first PUSCH includes a report of semi-persistent CSI (channel state information), the second PUSCH includes uplink data, and And if the transmission of the first PUSCH overlaps with the transmission of the second PUSCH in time, the terminal transmits the second PUSCH without transmitting the first PUSCH.

At this time, the control information may be DCI (downlink control information).

At this time, the control information may be received from the base station.

At this time, the first PUSCH or the second PUSCH may be transmitted to the base station.

In this case, the semi-permanent CSI may be a CSI transmitted at regular intervals during a predetermined time period.

At this time, the uplink data may be an UL-SCH (uplink shared channel).

According to another embodiment of the present invention, a user equipment (UE) includes a transceiver for transmitting and receiving a radio signal and a processor operating in combination with the transceiver, And transmitting the first PUSCH or the second PUSCH after receiving the control information, wherein the first PUSCH includes a report of semi-persistent CSI (channel state information), and the second PUSCH includes Wherein the terminal transmits the second PUSCH without transmitting the first PUSCH when the first PUSCH transmission time overlaps with the second PUSCH transmission in time. Can be provided.

According to the present invention, when the terminal can transmit only one uplink channel at the same time, it can be clarified which channel the terminal should prioritize transmission. More specifically, by preferentially transmitting the PUSCH for the uplink data, which is relatively important information than the PUSCH for the SP-CSI, the base station can reliably receive relatively important information. As a result, The stability can be increased.

1 illustrates a wireless communication system. This may be referred to as Evolved-UMTS Terrestrial Radio Access Network (E-UTRAN) or Long Term Evolution (LTE) / LTE-A system.

The E-UTRAN includes a base station (BS) 20 that provides a user plane (UE) with a control plane and a user plane. The terminal 10 may be fixed or mobile and may be referred to by other terms such as a mobile station (MS), a user terminal (UT), a subscriber station (SS), a mobile terminal (MT) . The base station 20 is a fixed station that communicates with the terminal 10 and may be referred to as another term such as an evolved NodeB (eNB), a base transceiver system (BTS), an access point, or the like.

The base stations 20 may be interconnected via an X2 interface. The base station 20 is connected to an S-GW (Serving Gateway) through an MME (Mobility Management Entity) and an S1-U through an EPC (Evolved Packet Core) 30, more specifically, an S1-MME through an S1 interface.

The EPC 30 is composed of an MME, an S-GW, and a P-GW (Packet Data Network-Gateway). The MME has information on the access information of the terminal or the capability of the terminal, and this information is mainly used for managing the mobility of the terminal. The S-GW is a gateway having an E-UTRAN as an end point, and the P-GW is a gateway having a PDN as an end point.

The layers of the radio interface protocol between the UE and the network are classified into L1 (first layer), L1 (second layer), and the like based on the lower three layers of the Open System Interconnection (OSI) A physical layer belonging to a first layer provides an information transfer service using a physical channel, and a physical layer (physical layer) An RRC (Radio Resource Control) layer located at Layer 3 controls the radio resources between the UE and the network. To this end, the RRC layer exchanges RRC messages between the UE and the BS.

2 is a block diagram illustrating a radio protocol architecture for a user plane. 3 is a block diagram illustrating a wireless protocol structure for a control plane. The user plane is a protocol stack for transmitting user data, and the control plane is a protocol stack for transmitting control signals.

Referring to FIGS. 2 and 3, a physical layer (PHY) provides an information transfer service to an upper layer using a physical channel. The physical layer is connected to a MAC (Medium Access Control) layer, which is an upper layer, through a transport channel. Data is transferred between the MAC layer and the physical layer through the transport channel. The transport channel is classified according to how the data is transmitted through the air interface.

Data moves between different physical layers, i. E., Between the transmitter and the physical layer of the receiver, over the physical channel. The physical channel can be modulated by an Orthogonal Frequency Division Multiplexing (OFDM) scheme, and uses time and frequency as radio resources.

The function of the MAC layer includes a mapping between a logical channel and a transport channel and a multiplexing / demultiplexing into a transport block provided as a physical channel on a transport channel of a MAC SDU (service data unit) belonging to a logical channel. The MAC layer provides a service to a Radio Link Control (RLC) layer through a logical channel.

The function of the RLC layer includes concatenation, segmentation and reassembly of the RLC SDUs. The RLC layer includes a Transparent Mode (TM), an Unacknowledged Mode (UM), and an Acknowledged Mode (RB) in order to guarantee various QoSs required by a radio bearer (RB) , And AM). AM RLC provides error correction via automatic repeat request (ARQ).

The Radio Resource Control (RRC) layer is defined only in the control plane. The RRC layer is responsible for the control of logical channels, transport channels and physical channels in connection with the configuration, re-configuration and release of radio bearers. RB means a logical path provided by a first layer (PHY layer) and a second layer (MAC layer, RLC layer, PDCP layer) for data transmission between a UE and a network.

The functions of the Packet Data Convergence Protocol (PDCP) layer in the user plane include transmission of user data, header compression and ciphering. The functions of the Packet Data Convergence Protocol (PDCP) layer in the control plane include transmission of control plane data and encryption / integrity protection.

The setting of the RB means a process of defining characteristics of a radio protocol layer and a channel to provide a specific service, and setting each specific parameter and an operation method. RB can be divided into SRB (Signaling RB) and DRB (Data RB). The SRB is used as a path for transmitting the RRC message in the control plane, and the DRB is used as a path for transmitting the user data in the user plane.

When an RRC connection is established between the RRC layer of the UE and the RRC layer of the E-UTRAN, the UE is in the RRC connected state, and if not, the UE is in the RRC idle state.

The downlink transmission channel for transmitting data from the network to the terminal includes a BCH (Broadcast Channel) for transmitting system information and a downlink SCH (Shared Channel) for transmitting user traffic or control messages. In case of a traffic or control message of a downlink multicast or broadcast service, it may be transmitted through a downlink SCH, or may be transmitted via a separate downlink MCH (Multicast Channel). Meanwhile, the uplink transmission channel for transmitting data from the UE to the network includes a random access channel (RACH) for transmitting an initial control message and an uplink SCH (Shared Channel) for transmitting user traffic or control messages.

A logical channel mapped to a transport channel is a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), a multicast traffic Channel).

A physical channel is composed of several OFDM symbols in the time domain and a plurality of sub-carriers in the frequency domain. One sub-frame is composed of a plurality of OFDM symbols in the time domain. A resource block is a resource allocation unit, and is composed of a plurality of OFDM symbols and a plurality of sub-carriers. In addition, each subframe can use specific subcarriers of specific OFDM symbols (e.g., first OFDM symbol) of a corresponding subframe for a physical downlink control channel (PDCCH), i.e., an L1 / L2 control channel. The TTI (Transmission Time Interval) is the unit time of the subframe transmission.

Hereinafter, a new radio access technology (new RAT) will be described. The new radio access technology may be abbreviated as NR (new radio).

As more and more communication devices require greater communication capacity, there is a need for improved mobile broadband communication over existing radio access technology (RAT). Also, Massive Machine Type Communications (MTC), which provides various services by connecting many devices and objects, is one of the major issues to be considered in next generation communication. In addition, communication system design considering service / terminal sensitive to reliability and latency is being discussed. The introduction of the next generation wireless access technology considering enhanced mobile broadband communication, massive MTC, URLLC (Ultra-Reliable and Low Latency Communication) is discussed. In the present invention, Is called new RAT or NR.

FIG. 4 illustrates a system structure of a next generation radio access network (NG-RAN) to which NR is applied.

Referring to FIG. 4, the NG-RAN may include a gNB and / or an eNB that provides a user plane and control plane protocol termination to the terminal. FIG. 4 illustrates a case where only gNB is included. The gNB and the eNB are interconnected by an Xn interface. The gNB and the eNB are connected to the 5G Core Network (5G Core Network: 5GC) via the NG interface. More specifically, an access and mobility management function (AMF) is connected through an NG-C interface, and a UPF (user plane function) is connected through an NG-U interface.

Figure 5 illustrates functional partitioning between NG-RAN and 5GC.

Referring to FIG. 5, the gNB includes inter cell inter-cell RRM, RB control, connection mobility control, radio admission control, measurement setup and provisioning (Measurement Configuration & Provision), dynamic resource allocation, and the like. AMF can provide functions such as NAS security, idle state mobility handling, and so on. The UPF can provide functions such as mobility anchoring, PDU processing, and the like. The SMF (Session Management Function) can provide functions such as terminal IP address assignment, PDU session control, and the like.

≪ 3GPP LTE and NR (New RAT) >

LTE and NR will be described below. With the TS 36 series of the 3GPP specification, as more and more communication devices require greater communication capacity, there is a need for improved mobile broadband communication over existing radio access technologies. Massive MTC (Machine Type Communications), which provides various services by connecting many devices and objects, is one of the major issues to be considered in next generation communication. In addition, communication system design considering reliability / latency sensitive service / UE is being discussed.

The next generation of radio access technology (RAT), which considers such extended mobile broadband communications (eMBB), massive MTC (mMTC), URLLC (Ultra-Reliable and Low Latency Communication) And the technology is referred to as NR (New RAT) for convenience in the present invention.

<Self-contained subframe structure>

In order to minimize the latency in the fifth generation NR, a structure in which the control channel and the data channel are TDM as shown in the following figure can be considered as one of the frame structures.

6 schematically illustrates an example of a frame structure based on a structure in which a data channel and a control channel are TDM (Time Division Multiplexing).

Referring to FIG. 6, as an example of a frame structure, one subframe (where a subframe may be mixed with a name of a transmission time interval (TTI)) includes an index and a symbol of a resource block (RB) &Lt; / RTI &gt; At this time, one TTI may include a downlink control channel related region, an uplink control channel related region, and a downlink or uplink region.

For example, the TTI structure will be described with reference to FIG. 6, wherein the hatched area indicates a downlink control area and the black area indicates an uplink control area. The area without the mark may be used for downlink data transmission or for uplink data transmission. This structure is characterized in that downlink (DL) transmission and uplink (UL) transmission are sequentially performed in one subframe, DL data is transmitted in a subframe, and UL ack / nack (Acknowledged / Not Acknowledged). As a result, it is possible to reduce the time taken to retransmit the data when a data transmission error occurs, thereby minimizing the latency of the final data transmission.

In the structure of data and control TDMed subframe structure in which such data and control are TDM, there is a time gap for the transition process from the transmission mode to the reception mode or from the reception mode to the transmission mode, need. For this purpose, some OFDM symbols at the time of switching from DL to UL in a subframe structure are set as a guard period (GP).

<Analog beamforming>

In the case of mmW, the wavelength is shortened, and a plurality of antennas can be installed in the same area. That is, in the 30 GHz band, a total of 100 antenna elements can be installed in a 2-dimensional array of 0.5 lambda (wavelength) intervals on a panel of 5 by 5 cm with a wavelength of 1 cm. Therefore, in the mmW, a plurality of antenna elements are used to increase the beamforming (BF) gain to increase the coverage or to increase the throughput.

In this case, if a TXRU (transceiver unit) is provided so that transmission power and phase can be adjusted for each antenna element, independent beamforming can be performed for each frequency resource. However, installing a TXRU on all 100 antenna elements has a problem in terms of cost effectiveness. Therefore, a method of mapping a plurality of antenna elements to one TXRU and adjusting the direction of a beam with an analog phase shifter is considered. Such an analog beamforming method has a disadvantage that it can not perform frequency selective beaming since it can make only one beam direction in all bands.

Hybrid beamforming (hybrid BF) with B TXRUs that are fewer than Q antenna elements in the middle of digital beamforming (Digital BF) and analog beamforming (analog BF) can be considered. In this case, although there is a difference depending on the connection method of B TXRU and Q antenna elements, the number of beams that can be transmitted at the same time is limited to B or less.

<Analog beamforming - 2>

In the NR system, when a plurality of antennas are used, a hybrid beamforming technique combining digital beamforming and analog beamforming is emerging. In this case, analog beamforming (or RF beamforming) refers to an operation of performing precoding (or combining) in the RF stage.

In the hybrid beamforming, the baseband stage and the RF stage respectively perform Precoding (or Combining), thereby reducing the number of RF chains and the number of D / A (or A / D) beamforming performance.

For convenience, the hybrid beamforming structure may be represented by N transceiver units (TXRU) and M physical antennas. Then, digital beamforming for the L data layers to be transmitted at the transmitting end can be represented by N by L matrix, and then converted N digital signals are converted into analog signals through TXRU And the analog beamforming expressed by the M by N matrix is applied.

For ease of understanding, the hybrid beamforming structure is schematically illustrated in terms of TXRU and physical antennas as follows.

Figure 7 schematically illustrates a hybrid beamforming structure in terms of TXRU and physical antennas.

According to the example of FIG. 7, the number of digital beams is L, and the number of analog beams is N. Further, in the NR system, the base station is designed to change the analog beamforming in symbol units, thereby considering more efficient beamforming for the terminal located in a specific area.

In the example of FIG. 7, when a specific N TXRU and M RF antennas are defined as one antenna panel, the NR system may include a plurality of antenna panels Is also being considered.

In the case where the base station utilizes a plurality of analog beams as described above, since the analog beams advantageous for signal reception may differ from terminal to terminal, at least a synchronization signal, system information, paging, There is considered a beam sweeping operation in which a plurality of analog beams to be applied by a base station in a specific subframe (SF) are changed for each symbol to enable all terminals to have a reception opportunity.

Hereinafter, the beam sweeping operation of the synchronization signal and the system information in the downlink transmission process will be described in more detail with reference to the drawings.

8 schematically shows an example of a beam sweeping operation for a synchronization signal and system information in a downlink transmission process.

Referring to FIG. 8, a physical resource (or a physical channel) through which system information of an NR system is transmitted in a broadcasting manner may be referred to as an xPBCH (physical broadcast channel).

Within a symbol, analog beams belonging to different antenna panels can be transmitted simultaneously, and a single analog beam (corresponding to a particular antenna panel) is applied to measure the channel by analog beam, Beam RS (BRS), which is a reference signal (RS), can be introduced.

The BRS may be defined for a plurality of antenna ports, and each antenna port of the BRS may correspond to a single analog beam. In this case, unlike the BRS, the synchronization signal or the xPBCH can be transmitted by applying all the analog beams in the analog beam group so that the arbitrary terminal can receive the synchronization signal.

<Radio Resource Management (RRM) measurement>

In the LTE system, a power control, a scheduling, a cell search, a cell reselection, a handover, a radio link or a connection monitoring (monitoring) ), Connection establishment / re-establishment, and the like.

In this case, the Serving Cell may request RRM measurement information, which is a measurement value for performing RRM operation, to the UE. Typically, in the LTE system, the UE transmits cell search information, RSRP (reference signal received power, and reference signal received quality (RSRQ).

Specifically, in the LTE system, a UE receives 'measConfig' as an upper layer signal for RRM measurement from a Serving Cell. The UE measures RSRP or RSRQ according to the 'measConfig' information. Here, the definition of RSRP and RSRQ according to the LTE system may be as follows.

- RSRP:

The reference signal received power (RSRP) is defined as the linear average on the power contribution of the resource element carrying the cell specific reference signal within the considered measurement frequency bandwidth. The cell specific reference signal R0 according to TS 36 series can be used for RSRP decision. If the UE is reliably detecting that R1 is available, it may use R1 in addition to R0 to determine the RSRP.

The reference point for RSRP may be the antenna connector of the UE.

If the receiver diversity is in use by the UE, the reported value will not be lower than the corresponding RSRP of any of the individual diversity branches.

- RSRQ:

Reference Signal Received Quality (RSRQ) is defined as a ratio N * RSRP / (E-UTRA carrier RSSI). Here, N is the number of resource blocks (RBs) of the E-UTRA carrier RSSI measurement bandwidth. Measurements at the numerator and denominator will be made on the same set of resource blocks.

The E-UTRA Carrier Received Signal Strength Indicator (RSSI) is a measure of the measured bandwidth on the N number of resource blocks by the UE from all sources, including co-channel serving and non-serving cells, adjacent channel interference, thermal noise, And compares the linear average of the total received power observed (in watts [W]) in the OFDM symbols containing the reference symbols for port 0.

If upper layer signaling represents any subframe for performing RSRQ measurements, the RSSI is measured on all OFDM symbols in the indicated subframe.

The reference point for RSRQ may be the antenna connector of the UE. If the receiver diversity is in use by the UE, the reported value will not be lower than the corresponding RSRP of any of the individual diversity branches.

- RSSI:

RSSI may refer to received broadband power, including thermal noise and noise, occurring at the receiver within the bandwidth defined by the receiver pulse shaping filter.

The reference point for measurement may be an antenna connector of the terminal. If receiver diversity is used by the terminal, the reported value will not be lower than the corresponding UTRA carrier RSSI of any individual receive antenna branch.

According to the above definition, when the UE operating in the LTE system is an Intra-frequency measurement, the UE determines whether an information element (IE) related to an allowed measurement bandwidth (SIB) 15, 25, 50, 75, and 100RB (resource blocks) through the allowed measurement bandwidth transmitted from the SIB 5 in case of inter-frequency measurement Or in the frequency band of the entire downlink (DL) system by default if there is no such IE. &Lt; RTI ID = 0.0 &gt;

In this case, when the terminal receives the allowed measurement bandwidth, the terminal considers the corresponding value as the maximum measurement bandwidth and can freely measure the RSRP value within the corresponding value.

However, if the Serving Cell transmits an IE defined as WB-RSRQ and the allowed measurement bandwidth is set to 50RB or more, the UE transmits an RSRP The value should be calculated. On the other hand, the RSSI is measured in the frequency band of the receiver of the terminal according to the definition of the RSSI bandwidth.

Hereinafter, the present invention will be described.

Recently, the 3GPP standardization group is considering a network slicing scheme for implementing a plurality of logical networks on a single physical network in a NR (New RAT) system, which is a 5G wireless communication system.

The logical network must be able to support services with various requirements (eg, enhanced mobile broadband (eMBB), massive machine type communications (mMTC), ultra-reliable low latency communications (URLLC) In the physical layer system, a scheme of supporting an orthogonal frequency division multiplexing (OFDM) scheme capable of having variable Numerology according to the various services is considered. In other words, in the New RAT system, an OFDM scheme (or a multiple access scheme) having mutually independent neurons for each time and frequency resource region can be considered.

In the New RAT system, a basic time unit for data scheduling is defined as a slot composed of a plurality of OFDM symbols, and latency for transmission of HARQ-ACK (or decoding result) A method for transmitting a Physical Uplink Control Channel (PUCCH), which is a physical channel for UL control signal transmission, with a data channel in a relatively short time interval as shown in FIG. 6 is being discussed.

Hereinafter, for convenience of description, the PUCCH transmitted in a short time interval corresponding to several OFDM symbols (e.g., one or two) in a slot is referred to as a Short PUCCH. For example, the Short PUCCH may have a length of one or two OFDM symbols. After determining HARQ-ACK (or decoding result) for DL (downlink) data in the same slot, May report the HARQ-ACK (or decoding result) information to the base station through a Short PUCCH.

On the other hand, the PUCCH, which is composed of a predetermined number (e.g., four) OFDM symbols and is transmitted for a relatively long time in a slot, is referred to as a Long PUCCH.

For example, if the amount of uplink control information (UCI) to be transmitted on the Short PUCCH is small (eg, 1 or 2 bits), the base station allocates a sequence set composed of a plurality of sequences to the terminal as Short PUCCH resources , And the UE can select and transmit a specific sequence corresponding to the UCI information to be transmitted among the sequences allocated to the Short PUCCH resource.

At this time, the sequence may be designed to satisfy a Low PAPR (peak power to average power ratio) characteristic. Hereinafter, the sequence-based Short PUCCH structure is referred to as SEQ-PUCCH for convenience of explanation.

In the case where the amount of information of the UCI to be transmitted to the Short PUCCH is large (eg, more than 3 bits), the BS transmits a short message including REs for transmission of UCI and resource elements (REs) PUCCH resources.

In this case, the RS transmission RE and the UCI transmission RE may be classified according to the FDM scheme for each symbol. The terminal generates coded bits for the UCI, and then generates a modulation symbol for the coded bits (modulated symbols) to the REs for UCI transmission. Hereinafter, the Short PUCCH structure to which the FDM scheme between the RS and the UCI (per symbol) is applied is referred to as an FDM-PUCCH.

Meanwhile, in the New RAT system, semi-persistent CSI (hereinafter referred to as SP-CSI) transmission operation in which channel state information (CSI), which is channel state information, is transmitted at regular intervals over a predetermined time interval is considered.

The SP-CSI transmission can be regarded as a type of multi-shot transmission within a predetermined time interval.

More specifically, the BS sets a CSI reporting period and a physical uplink shared channel (PUSCH) resource (eg, time and frequency resources) for CSI transmission to an upper layer signal such as RRC signaling, CSI transmission with the CSI reporting period and the CSI transmission PUSCH resource via downlink control information (DCI) (e.g., UL (uplink) grant) . At this time, the terminal can perform a CSI report transmission according to the period and the resource only during the active time period, and the SP-CSI report transmitted through the period and the resources can be transmitted to one or more CSI parts (Eg, CSI prat 1 and CSI part 2).

The present invention proposes a terminal operation when the SP-CSI transmission PUSCH collides with another PUCCH or PUSCH when the SP-CSI is transmitted as a PUSCH resource. In addition, We propose an allocation scheme.

In the present invention, the PUCCH resource includes a PUCCH transmission timing (eg, a starting slot, a starting symbol), a PUCCH duration (eg, a number of symbols in a slot a physical PRB index, a number of PRBs, a frequency hopping enable / disable, a physical resource allocation (PRB) allocation, Code domain resource (e.g., an initial cyclic shift, a time-domain OCC, and a pre-DFT OCC).

In the present invention, A-CSI (aperiodic CSI) means CSI reported non-periodically, and P-CSI (periodic CSI) means CSI reported periodically. In the following description, the PUSCH for transmitting the SP-CSI as UL data is referred to as the SP-CSI transmission PUSCH.

Hereinafter, in order to maintain a single carrier property (or a low PAPR or a low Cubic metric characteristic) at least at specific terminals in the present invention, one UL channel Is transmitted.

More specifically, a semi-persistent transmission of CSI using PUSCH or PUCCH resources (i.e., an operation of transmitting CSI at regular intervals during a predetermined time interval) is supported in a wireless communication system including a base station and a terminal 1. First, the contents of the terminal operation at the time of collision between the PUSCH transmitting the semi-persistent CSI (SP-CSI) and another UL physical channel (eg, PUCCH or PUSCH) will be described first. 2. SP- The PUCCH resource allocation scheme for the SP-CSI transmission will be described, and then, how the SP-CSI will be transmitted on the PUSCH will be described.

One. SP To send -CSI PUSCH and  Other UL physical channels (e.g., PUCCH  or PUSCH If there is a conflict, the conflict handling method.

As described above, in order to perform the transmission of the PUSCH related to the SP-CSI or the transmission of another UL physical channel at the same time (when the transmission overlaps or partially overlaps) Other) DCI. In the above situation, when the UE can transmit only one uplink channel at the same time, if it is unclear which channel the transmission of the channel will be prioritized, there is a problem that important information to be transmitted by the UE is not transmitted .

Accordingly, in the present invention, when the UE collides with the transmission of the PUSCH related to the SP-CSI and the transmission of another UL physical channel at the same time, the UE performs some transmission and does not perform any transmission (e.g., ).

Although not described in separate drawings, the following description will be generalized. The terminal may receive control information (e.g., DCI) from the base station. After receiving the control information, the UE determines whether transmission of the PUSCH related to the SP-CSI and transmission of another UL physical channel overlap in time. Then, the UE performs transmission of the PUSCH related to the SP-CSI or transmission of another UL physical channel based on the determination.

Hereinafter, a collision handling method for a case where a PUSCH that transmits SP-CSI and another uplink channel collide will be described in more detail.

<Conflict handling method in case of conflict between PUSCH and PUCCH transmitting SP-CSI>

[Suggestion # 1] SP-CSI transmission PUSCH resources and specific UCI-X (eg, HARQ-ACK, P-CSI, A-CSI, SR) if the (short) PUCCH resource has (partially) overlapping time-axis transmission resources, the UE can operate as follows.

(1) Opt. 1: UCI-X transmission (short) Only PUCCH resource transmission and SP-CSI transmission can be omitted.

(2) Opt. 2: SP-CSI transmission Only PUSCH resources are transmitted, and UCI-X transmission can be omitted.

(3) Opt. 3: UCI-X is piggybacked on the SP-CSI transmission PUSCH to be transmitted together, and PUCCH transmission can be omitted.

(4) Opt. 4: UCI-X and SP-CSI can be transmitted together with PUSCH or PUCCH resources.

A. However, UCI-X and SP-CSI can be joint-coding or separate-coding, and when transmitted on the PUSCH, they can be mapped as RE (resource element) .

B. However, the PUSCH / PUCCH resource may be a resource allocated for UCI-X and SP-CSI, or may be a separately set resource.

(5) Opt. 5: SP-CSI transmission PUSCH and UCI-X transmission (short) PUCCH can be transmitted by TDM.

A. However, SP-CSI in the symbol interval overlapping with the X-CSI transmission (short) PUCCH resource in the SP-CSI transmission PUSCH can be punctured.

However, the base station can instruct the terminal to follow a specific operation among the options through the upper layer signal and / or the DCI. Or the terminal may follow a specific one of the Options according to a specific condition.

However, the SP-CSI can be transmitted according to the same encoding / mapping process as the general UL data in the PUSCH.

(For example, HARQ-ACK, P-CSI, A-CSI, SR, etc.) different from the SP-CSI transmission PUSCH when the mobile station transmits SP-CSI as a PUSCH resource short) PUCCH resources may (partially) overlap time-axis transmission resources.

In this case, the UE can transmit only the UL channel having the higher priority UCI (Opt. 1 or Opt. 2) or transmit the SP-CSI and UCI-X with the same PUSCH or PUCCH resource (Opt. Or Opt. 4).

In this case, when SP-CSI and UCI-X are transmitted together on the PUSCH, the SP-CSI can be transmitted in data format, UCI-X can be transmitted in UCI piggyback format, or both can be transmitted in data format. If the UCI-X transmission PUCCH resource is a short PUCCH resource, it can puncture a partial symbol interval of the SP-CSI transmission PUSCH and transmit the UCI-X transmission (short) PUCCH by TDM.

[Proposed Scheme # 1] may be combined and applied together as long as it is not interposed with other proposals of the present invention.

< SP To send -CSI PUSCH and  (Other) PUSCH  Conflict Handling Method During Conflicts>

[Suggestion # 2] The SP-CSI transmission PUSCH (PUSCH 1) resource and the UL data transmission PUSCH resource (PUSCH 2) are transmitted (in the same or different DCI) In the case of having resources, the terminal can operate as follows.

(1) Opt. 1: UCI piggyback transmission of SP-CSI to PUSCH 2, and PUSCH 1 transmission may be omitted.

(2) Opt. 2: Only PUSCH 2 transmission and SP-CSI transmission can be omitted.

A. In this case, PUSCH 2 may be a PUSCH according to dynamic scheduling and the corresponding scheduling may override PUSCH 1.

(3) Opt. 3: CSI parts 1 and 2 for SP-CSI can be divided into PUSCH 1 and PUSCH 2, respectively.

A. However, the CSI part transmitted on PUSCH 1 is transmitted in data format, and the CSI part transmitted on PUSCH 2 can be transmitted in UCI piggyback format.

However, the base station can instruct the terminal to follow a specific operation among the options through the upper layer signal and / or the DCI.

For example, when the UE transmits the SP-CSI as a PUSCH resource, the SP-CSI transmission PUSCH and the PUSCH resource for transmitting the actual UL data may have (partially overlapping) time-axis transmission resources.

In this case, the UE can prioritize the data scheduling PUSCH (PUSCH 2) because it has performed the UL data transmission PUSCH (PUSCH 2) scheduling even though the base station knows the existence of the SP-CSI transmission PUSCH (PUSCH 1).

At this time, the SP-CSI may be UCI piggybacked (Opt. 1) or omitted (Opt.2) in the data scheduling PUSCH (PUSCH 2). Alternatively, when the UE can transmit both PUSCHs, the SP-CSI can be divided into two parts and then divided into PUSCH (PUSCH 1) and PUSCH (PUSCH 2) allocated to the SP-CSI.

At this time, the CSI part transmitted in the PUSCH (PUSCH 1) for the SP-CSI is transmitted in data format, and the CSI part transmitted in the data scheduling PUSCH (PUSCH 2) can be transmitted in the UCI piggyback format.

For the convenience of understanding, among the contents of [Proposal Scheme # 2] (that is, an example of how the terminal transmits the PUSCH related to the SP-CSI), Opt. 2 will be described with reference to the drawings as a whole including the terminal and the base station as follows.

9 is a schematic diagram illustrating an embodiment of a method of transmitting a PUSCH related to SP-CSI, according to an embodiment of the present invention.

Referring to FIG. 9, a terminal may receive control information (e.g., DCI (downlink control information)) from a base station (S910).

For example, the UE may be instructed via the DCI to activate / release the SP-CSI transmission with the CSI reporting period and the CSI transmission PUSCH resource. Here, examples of the DCI are the same as those described above, so that the description of the overlapping contents will be omitted for convenience of explanation.

After receiving the control information, the mobile station transmits a first PUSCH (including semi-permanent CSI report) or a second PUSCH (including uplink data) (S920). That is, after receiving the control information, the UE may transmit at least one first PUSCH and / or a second PUSCH.

Here, if the transmission of the first PUSCH and the transmission of the second PUSCH are overlapped in time, the UE can perform the transmission of the second PUSCH without performing the transmission of the first PUSCH.

That is, when the terminal overlaps the transmission time of the PUSCH including the semi-permanent CSI report and the transmission time of the PUSCH including the uplink data over time, the PUSCH including the semi-permanent CSI report (or the PUSCH related to the semi-permanent CSI) (I.e., dropping the transmission of the PUSCH including the semi-persistent CSI report) and perform transmission of the PUSCH including the uplink data (i.e., the PUSCH related to the uplink data) without performing transmission.

In this example, the control information may be DCI (downlink control information). Also in one example, the control information may be received from a base station. In addition, the first PUSCH or the second PUSCH may be transmitted to the base station. For example, the semi-permanent CSI may be a CSI transmitted at regular intervals during a predetermined time period. For example, the uplink data may be an UL-SCH (uplink shared channel).

Here, the first PUSCH (including semi-permanent CSI report) and / or the second PUSCH (e.g., uplink data) described above may be transmitted in one subframe (or TTI) Quot; PUSCH &quot; That is, the first PUSCH and / or the second PUSCH may be a PUSCH in a subframe (or TTI) composed of 14 symbols as described above.

The contents of FIG. 9 may be expressed in other ways as follows. First, the terminal determines whether the transmission of the first PUSCH and the transmission of the second PUSCH overlap in time. Thereafter, the terminal may transmit the first PUSCH or the second PUSCH to the base station (i.e., the terminal transmits at least one first PUSCH and / or the second PUSCH) based on the determination. Here, the first PUSCH is a PUSCH related to semi-persistent CSI, the second PUSCH is a PUSCH related to uplink data, and when the first PUSCH transmission and the second PUSCH transmission overlap in time, The transmission of the second PUSCH can be performed without performing the transmission. Here, the first PUSCH or the second PUSCH may be transmitted based on the DCI.

According to the embodiment of FIG. 9, when the UE can transmit only one uplink channel at the same time, it is necessary to clearly define which channel the UE should prioritize transmission. More specifically, by preferentially transmitting the PUSCH for the uplink data, which is relatively important information than the PUSCH for the SP-CSI, the base station can reliably receive relatively important information. As a result, The stability can be increased.

As another possibility, it is possible to consider multiplexing the SP-CSI with the data on the second PUSCH in the state where the first PUSCH transmission is omitted. In this case, if the terminal receives the control information indicating the activation for the SP- A discrepancy may occur between the terminal and the base station in the presence of the SP-CSI and the corresponding first PUSCH. This may result in inconsistency between the terminal and the base station with respect to the data mapping position on the second PUSCH, which may significantly degrade the data transmission performance.

Therefore, by preferentially transmitting the PUSCH for the uplink data, which is relatively important information as compared with the PUSCH for the SP-CSI, as described above, the base station can reliably receive relatively important information, The stability can be increased.

The contents of FIG. 9 will be described from the viewpoint of a terminal as follows.

Thereafter, the UE performs transmission of a first PUSCH (including semi-permanent CSI report) or a second PUSCH (e.g., uplink data) after receiving the control information, wherein the transmission of the first PUSCH and the transmission of the second PUSCH In case of overlapping in time, the transmission of the second PUSCH may be performed without performing the transmission of the first PUSCH (S1020).

As a concrete example of this, as described above, repetitive descriptions of overlapping contents are omitted for convenience of explanation.

As described above, the BS can receive the second PUSCH in the time when the transmission of the first PUSCH by the UE and the transmission of the second PUSCH overlap in time. As a concrete example of this, as described above, repetitive descriptions of overlapping contents are omitted for convenience of explanation.

As described above, the BS can receive the second PUSCH in the time when the transmission of the first PUSCH by the UE and the transmission of the second PUSCH overlap in time. As a concrete example of this, as described above, repetitive descriptions of overlapping contents are omitted for convenience of explanation.

[Proposition # 2] above may be combined and applied together as long as they are not interleaved with other proposals of the present invention.

Hereinafter, a medium access control-control element (MAC-CE) refers to control information indicated in a MAC layer higher than a physical layer (e.g., PHY layer).

2. SP -CSI PUCCH  When transmitting to a resource, SP For CSI transmission PUCCH  Resource allocation

As described above, the terminal can transmit the SP-CSI. At this time, when it is unclear how the PUCCH resource to be allocated for the SP-CSI transmission is unknown when the terminal transmits the SP-CSI, there arises a problem that it is unclear how the terminal will transmit the SP-CSI It is possible.

Accordingly, in the present invention, when a mobile station transmits an SP-CSI, it provides information on how to allocate PUCCH resources for SP-CSI transmission.

Although not described in separate drawings, the following description will be generalized. First, the terminal can receive information on resources from the base station. The UE can then transmit the SP-CSI on the PUCCH based on the received information on the resource.

Hereinafter, how the PUCCH resources for SP-CSI transmission will be allocated when the terminal transmits SP-CSI will be described in more detail.

<Resource allocation for SP-CSI on PUCCH>

[Proposition # 3] When activating / releasing the operation of transmitting SP-CSI as a PUCCH resource with the MAC-CE, a method of allocating the SP-CSI transmission PUCCH resource as follows may be provided to the base station.

(1) Opt. 1: A plurality of PUCCH resources may be set to the UE by an upper layer signal (e.g., RRC signaling), and one PUCCH resource may be designated by MAC-CE (and / or DCI).

Although not shown separately, for example, the terminal can receive information on a plurality of PUCCH resources through an upper layer signal. Then, the UE can receive a resource of one PUCCH among a plurality of PUCCH resources, for example, through the DCI based on the information on the received PUCCH resources.

(2) Opt. 2: Both PUCCH and PUSCH resources can be set to the UE by an upper layer signal (e.g., RRC signaling), and one PUCCH or PUSCH resource can be designated by MAC-CE (and / or DCI).

For convenience of explanation, although not shown separately, the terminal can receive information on a plurality of PUCCH resources and PUSCH resources through an upper layer signal. Thereafter, the UE can receive a PUCCH resource or a PUSCH resource among a plurality of PUCCH resources and PUSCH resources through DCI, for example, based on the received PUCCH resources and PUSCH resource information.

However, the MAC-CE used for the PUCCH resource allocation may be a MAC-CE indicating activation.

However, the SP-CSI transmission PUCCH resource may include frequency hopping related information (in symbol and / or slot units).

For example, the base station may enable or release the SP-CSI transmission over the PUCCH resource to the terminal with MAC-CE.

At this time, the base station may set a plurality of PUCCH resources in advance through an upper layer signal such as RRC signaling, and instruct the terminal to utilize one of the plurality of PUCCH resources for SP-CSI transmission through the MAC-CE.

More generally, the base station sets up a plurality of PUCCH or PUSCH resources for SP-CSI transmission to the MS as an upper layer signal such as RRC signaling, and then transmits a specific PUCCH or PUSCH resource To be used for SP-CSI transmission.

[Proposal # 3] may be combined and applied together as long as it is not interposed with other proposals of the present invention.

[Proposal # 4] When the operation of transmitting the SP-CSI to the PUCCH resource is activated by the MAC-CE, a method may be provided by the base station to release the SP-CSI transmission PUCCH resource as follows.

(1) Opt. 1: Single MAC-CE can indicate the time of release with activation indication.

A. As an example, it may indicate information on the time period during which SP-CSI transmission is performed (from the time of activation) or the total number of SP-CSI transmissions.

However, the UE can report ACK / NACK information for the MAC-CE reception to the BS.

In the LTE system, DCI was in charge of each role when activating / releasing the semi-persistent scheduling (PUSCH) based PUSCH. However, in the New RAT system according to the embodiment of the present invention, the PUCCH-based SP-CSI transmission can be activated by the MAC-CE, and since the MAC-CE is a control signal that can contain a relatively large amount of information as compared with the DCI, Release information for the CSI transport PUCCH can also be included. For example, the base station can further inform the BS through the single MAC-CE (from the point of activation) of the information on the interval in which the SP-CSI transmission is maintained.

[Proposition 4] may be combined and applied together as long as they are not interleaved with other proposals of the present invention.

3. How to transfer SP-CSI on the PUSCH.

&Lt; SP-CSI on PUSCH and SPS PUSCH >

[PROPOSED METHOD # 5] Semi-persistent scheduling (SPS) CSI reporting is performed at the activation DCI for the SPS PUSCH with a specific bit field (eg, CSI request field) in the DCI for activating / releasing the PUSCH. A method may be provided in which the terminal performs one or more of the following operations.

(1) SP-CSI can be transmitted for each SPS PUSCH.

(2) SP-CSI can be transmitted to the corresponding SPS PUSCH only when SPS PUSCH corresponding to (periodic) SP-CSI transmission time is transmitted.

A. However, the base station can independently set the transmission period for the SPS PUSCH and the transmission period for the SP-CSI through the upper layer signal, and the transmission period for the SP-CSI is a multiple of the transmission period for the SPS PUSCH .

For convenience of understanding, it is summarized as follows. First, the terminal can receive the DCI from the base station. The terminal then sends SP-CSI for each SPS PUSCH (1) based on the received DCI (upon receipt of the CSI reporting request from the active DCI), or (2) sends CSI reporting on the active DCI SP-CSI can be transmitted to the corresponding SPS PUSCH only when the SPS PUSCH corresponding to the SP-CSI transmission time is transmitted.

However, the manner in which the SP-CSI is transmitted to the SPS PUSCH may follow the UCI piggyback scheme.

For example, the BS may inform the MS whether or not to transmit the SP-CSI in the corresponding SPS PUSCH to the DCI that activates the SPS PUSCH.

If the transmission of the SP-CSI from the active DCI to the SPS PUSCH is instructed, it is assumed that the transmission period of the SPS PUSCH is the same as the transmission period of the SP-PUSCH, and the SP-CSI is included in the SPS PUSCH . Or when the base station sets the transmission period for the SPS PUSCH and the SP-CSI differently to the mobile station, when the transmission of the SP-CSI from the active DCI to the SPS PUSCH is instructed, the base station of the SPS PUSCH sets (periodically) The SP-CSI can be piggybacked by UCI only to the SPS PUSCH corresponding to the SP-CSI transmission time point.

[Proposed Scheme # 5] may be combined and applied together as long as they are not interleaved with other proposals of the present invention.
