Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a beam determination device, a terminal and a network side device. Background Art

[0002] In the New Radio (NR) system, the downlink channels include the Physical Downlink Shared Channel (PDSCH) and the Physical Downlink Control Channel (PDCCH); the uplink channels include the Physical Uplink Shared Channel (PUSCH) and the Physical Uplink Control Channel (PUCCH).

[0003] For high-frequency transmission (FR2 band in NR), due to the limited transmission range, the uplink and downlink channels are usually transmitted after beamforming to enhance coverage. The direction of the beamforming beam can be determined by beam scanning of the uplink and downlink reference signals, such as using the Channel State Information Reference Signal (CSI-RS) or Sounding Reference Signal (SRS) in different directions for beam scanning, and selecting the direction of the reference signal with the best beam quality for uplink or downlink transmission.

[0004] After determining the beam directions of different channels, it is necessary to use signaling to indicate the beam during channel transmission, that is, beam indication. For the PUCCH channel, the base station semi-statically configures multiple beam directions to the terminal through the high-level signaling SpatialRelationInfo, and indicates the activation of one of them through the Medium Access Control-Control Element (MAC-CE). For PUSCH, the uplink beam selected by the base station is indirectly indicated by the SpatialRelationInfo of the SRS resource indicated by the SRS Resource Indicator (SRI) field in the dynamic signaling downlink control information (Downlink Control Information, DCI). For the PDCCH channel, the base station configures multiple transmission configuration indication states (Transmission Configuration Indicator state, TCI state) for each control resource set (Control Resource Set, CORESET) through high-level signaling, and indicates the activation of one of them through MAC-CE. For the PDSCH channel, the base station indicates a TCI state through the TCI field in the DCI signaling, indicating the beam direction of the channel.

[0005] In the prior art solutions, different channels use different beam indication signaling, and each channel performs beam indication independently. In this way, different channels may use different beams for transmission. An important scenario in practical applications is that multiple channels use the same beam direction. For example, the PDCCH used for resource scheduling and the PDSCH for transmitting user data use the same beam direction for transmission; the uplink control channel PUCCH and the uplink data channel PUSCH also use the same beam direction. In addition, when beam reciprocity exists, the uplink channel and the downlink channel may also use the same beam direction. At this point, the current independent beam indication method increases the complexity of the system and the signaling indication overhead. Summary of the invention

[0100] See also Figure 1 , Figure 1 A block diagram of a wireless communication system applicable to an embodiment of the present invention is shown. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a user terminal or user equipment (UE, User Equipment), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 can be a base station and / or a core network element, wherein the above-mentioned base station can be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN access point, or other access point, etc.), wherein the base station can be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0101] The base station can communicate with the terminal 11 under the control of a base station controller, and in various examples, the base station controller can be part of the core network or certain base stations. Some base stations can communicate control information or user data with the core network via a backhaul. In some examples, some of these base stations can communicate with each other directly or indirectly via a backhaul link, which can be a wired or wireless communication link. The wireless communication system can support operations on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on these multiple carriers at the same time. For example, each communication link can be a multi-carrier signal modulated according to various radio technologies. Each modulated signal can be sent on a different carrier and can carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0102] The base station can communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​the access point can be divided into sectors that constitute only a portion of the coverage area.

The base station may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base station may be associated with the same or different access networks or operator deployments.

Downlink transmission may be performed using a licensed frequency band, an unlicensed frequency band, or both. Similarly, uplink transmission may be performed using a licensed frequency band, an unlicensed frequency band, or both.

[0104] The embodiment of the present invention provides a beam determination method, such as Figure 2 As shown, when the method is applied to the terminal side, it includes:

[0105] Step 21: The terminal determines whether the public beam state is in a valid state.

[0106] The embodiment of the present invention introduces a common beam state, wherein when the common beam state of the terminal is in a valid state, at least two channels and / or reference signals of the terminal will be transmitted using the same beam. When the common beam state of the terminal is in an invalid state, the existing method of independently indicating beams for different channels can still be used.

[0107] Specifically, the public beam state may be controlled by a network side device, such as a base station, or may be determined according to a pre-agreed effective time between the terminal and the network side. For example, the terminal may determine whether the public beam state is in a valid state based on the received public beam state indication information. For another example, the terminal determines whether the public beam state is in a valid state based on the pre-configured time that the public beam state is in a valid state.

[0108] When the common beam state indication information is used to control whether the common beam state of the terminal is valid, the common beam state indication information can be indicated by system information block 1 (System Information Block, SIB 1), high-level signaling or physical layer signaling. The high-level signaling includes radio resource control (Radio Resource Control, RRC) signaling, etc., and the physical layer signaling can be various DCIs, etc. The common beam state indication information is used to indicate at least one of the following information:

[0109] 1) The public beam state is valid.

[0110] When the common beam state is valid, at least two channels and / or reference signals of the terminal will be transmitted using the same beam.

[0111] 2) The effective time of the public beam state is the effective state.

[0112] Here, the public beam state indication information may include timer parameter indication information, and the timer parameter indication information is used to indicate the effective time of the public beam state as a valid state. Further, the public beam state indication information may also include an offset time parameter, and the offset time parameter is used to indicate that the public beam state becomes effective after the offset time indicated by the offset time parameter. The offset time is offset based on a certain reference time, and the reference time may specifically be a predefined time or the reception time of the public beam state indication information, etc.

[0113] 3) The public beam status is invalid.

[0114] When the common beam state is invalid, the existing method of independently indicating beams for different channels may be used to indicate the beams of various channels / reference signals.

[0115] As an implementation method, an embodiment of the present invention may define a dedicated public beam state information field in the public beam state indication information to indicate the public beam state. In this way, the terminal can determine whether the public beam state is in a valid state according to the value of the public beam state information field in the public beam state indication information. For example, when the value of the public beam state information field is 1, it indicates that the public beam state is in a valid state; when the value is 0, it indicates that it is in an invalid state.

[0116] As another implementation, an embodiment of the present invention can indicate the common beam state in an implicit manner. For example, a first radio network temporary identifier (Radio Network Temporary Identifier, RNTI) corresponding to a valid common beam state and a second RNTI corresponding to an invalid common beam state are predefined. When the network side indicates that the common beam state of the terminal is valid, it sends the common beam state indication information encrypted by the first RNTI; when indicating that the common beam state of the terminal is invalid, it sends the common beam state indication information encrypted by the second RNTI. In this way, the terminal can determine whether the common beam state is in a valid state according to whether the RNTI of the common beam state indication information successfully descrambled is a preset RNTI. For example, when the RNTI of the common beam state indication information successfully descrambled is the first RNTI, it is determined that the common beam state indicated at this time is a valid state; when the RNTI of the common beam state indication information successfully descrambled is the second RNTI, it is determined that the common beam state indicated at this time is an invalid state.

[0117] As another implementation method, the embodiment of the present invention can also use some domains in the prior art that are used to indicate other information other than the common beam state (referred to as existing information domains in this article) to indicate the common beam state. This / some existing information domain is a pre-defined domain that is originally used to indicate other information. There are usually some reserved values ​​in the values ​​of these domains, and these reserved values ​​are not used to indicate the above-mentioned other information. Therefore, the embodiment of the present invention can use the reserved values ​​of some / some existing information domains to indicate the common beam state. For example, whether the common beam state is in a valid state is determined based on whether the value of the existing information domain in the common beam state indication information is a preset value.

[0118] When the preconfigured time that the common beam state is in a valid state is used to indicate whether the common beam state of the terminal is valid, the terminal can determine the effective time that the common beam state is in a valid state according to a predefined time pattern for indicating whether the common beam state is valid or invalid, and determine whether the common beam state is in a valid state according to whether the current time is in the effective time. The time pattern can be predefined by the system, for example, a time pattern that has been preconfigured on both the network side and the terminal side. Alternatively, it is configured to the terminal by the network side through high-layer signaling or physical layer signaling.

[0119] In addition, the common beam state can also be determined according to a preset event on the terminal or network side. The preset event is an event predefined in the communication system including the terminal and the network side device, for example, it can be at least one of terminal beam scanning, terminal beam reporting, terminal beam failure, base station beam scanning and base station beam indication. The terminal beam scanning event can be specifically the terminal starting beam scanning, the terminal ending beam scanning, etc., and the present invention does not make specific restrictions on this. The terminal beam reporting is an event of reporting the beam scanning result to the network. The terminal beam failure is an event of a beam failure on the terminal side. The base station beam scanning is a beam scanning event of the base station for the terminal, which can be specifically the start of scanning or the end of scanning, etc. The event of the base station beam indication is that the base station gives a beam indication to the terminal.

[0120] Step 22: When the common beam state of the terminal is in a valid state, the terminal determines that at least two channels and / or reference signals of the terminal are transmitted using the same beam.

[0121] Here, the same beam can be a beam used by a preset channel or a preset reference signal, a beam used by a channel indicated by physical layer signaling or high-level signaling, a beam used by a reference signal indicated by physical layer signaling or high-level signaling, or a beam indicated by physical layer signaling or high-level signaling. The preset channel is one of PDCCH, PDSCH, PUCCH and PUSCH, and the preset reference signal is one of CSI-RS and SRS. The use of the same beam for transmission includes using the same beam for sending and / or receiving. When the same beam is a transmitting beam, using the same beam for receiving means receiving in the direction of the transmitting beam; when the same beam is a receiving beam, using the same beam for sending means sending in the direction of the receiving beam.

[0122] When the common beam state is valid, at least two channels and / or reference signals of the terminal use the same beam, where the at least two channels and / or reference signals are at least two of PDCCH, PDSCH, PUCCH, PUSCH, CSI-RS and SRS. For example, the at least two channels and / or reference signals may be PDCCH and PDSCH; or, the at least two channels and / or reference signals may be PDCCH, PDSCH and CSI-RS; or, the at least two channels and / or reference signals may be PUCCH and PUSCH; or, the at least two channels and / or reference signals may be PUCCH, PUSCH and SRS; or, the at least two channels and / or reference signals may be PDCCH and PUCCH, etc., and examples are not given one by one here.

[0123] When the common beam state is valid, the independent beam indication method of the prior art may be adopted, which will not be described in detail herein.

[0124] Through the above steps, the embodiment of the present invention can realize the indication of the common beam state, and at the same time indicate at least two channels and / or reference signals using the same beam. Since the beams of multiple channels / reference signals can be indicated at the same time, compared with the independent indication method of the prior art, the embodiment of the present invention can reduce the complexity of beam indication and the overhead of indication signaling. In addition, after adopting the method of the embodiment of the present invention, the common beam state can be used to realize the flexible switching of the terminal between the common beam and the independent beam, wherein the common beam refers to at least two channels and / or reference signals using the same beam for transmission.

[0125] After step 22, the terminal may receive or send the at least two channels and / or reference signals using the same beam.

[0126] For example, when the same beam is a transmitting beam, when sending the first channel or the first reference signal among the at least two channels and / or reference signals, the transmitting beam can be used to send the first channel or the first reference signal; when receiving the second channel or the second reference signal among the at least two channels and / or reference signals, the second channel or the second reference signal can be received in the direction of the transmitting beam.

[0127] Similarly, when the same beam is a receiving beam, when sending the first channel or the first reference signal among the at least two channels and / or reference signals, the first channel or the first reference signal can be sent in the direction of the receiving beam; when receiving the second channel or the second reference signal among the at least two channels and / or reference signals, the receiving beam can be used to receive the second channel or the second reference signal.

[0128] The above describes at least one implementation of the beam determination method of the present invention from the terminal side. Figure 3 The beam determination method provided in the embodiment of the present invention, when applied to a network side device, such as a base station, includes:

[0129] Step 31: The network side device determines whether the public beam state of the terminal is in a valid state.

[0130] Here, the network side device determines whether the common beam state of the terminal is in a valid state, which may specifically include at least one of the following:

[0131] 1) The network side device can determine whether the public beam state of the terminal is in a valid state according to the public beam state configured by itself for the terminal.

[0132] 2) The network side device determines whether the public beam state of the terminal is in a valid state according to the pre-configured time that the public beam state is in a valid state.

[0133] Among them, when determining whether the public beam state of the terminal is in a valid state according to the preconfigured time that the public beam state is in a valid state, the network side device can determine the effective time that the public beam state of the terminal is in a valid state according to a predefined time pattern for indicating whether the public beam state is valid or invalid, and determine whether the public beam state is in a valid state according to whether the current time is in the effective time.

[0134] 3) The network side device determines whether the public beam state is in a valid state according to a preset event on the terminal / network side.

[0135] Here, the preset event includes at least one of terminal beam scanning, terminal beam reporting, terminal beam failure, base station beam scanning and base station beam indication.

[0136] Step 32: When the terminal is in a valid state in a common beam state, the network side device determines that at least two channels and / or reference signals of the terminal are transmitted using the same beam.

[0137] Here, the same beam is a beam used by a preset channel or a preset reference signal; or, the same beam is a beam used by a channel / reference signal indicated by physical layer signaling or high-layer signaling; or the same beam is a beam indicated by physical layer signaling or high-layer signaling. The preset channel is one of PDCCH, PDSCH, PUCCH and PUSCH, and the preset reference signal is one of CSI-RS and SRS. The at least two channels and / or reference signals include at least two of PDCCH, PDSCH, PUCCH, PUSCH, CSI-RS and SRS. The use of the same beam for transmission includes sending and / or receiving using the same beam. When the same beam is a transmitting beam, receiving using the same beam means receiving in the direction of the transmitting beam; when the same beam is a receiving beam, sending using the same beam means sending in the direction of the receiving beam.

[0138] Through the above steps, in the embodiment of the present invention, the network side can determine the common beam state of the terminal, and then transmit the corresponding channel and / or reference channel according to the determined state, and the transmission includes sending and / or receiving. Since the common beam state that can simultaneously indicate multiple channel / reference signal beams is introduced, the embodiment of the present invention can reduce the complexity of beam indication and the overhead of indication signaling. In addition, in the embodiment of the present invention, when the common beam state is valid, multiple channels and / or reference signals use the same beam; and when the common beam state fails, the existing method of independently performing beam indication on different channels can still be used, so that the terminal can flexibly switch between the common beam and the independent beam.

[0139] After the above step 33, the network side device may also send public beam state indication information for configuring the public beam state to the terminal according to the public beam state configured by itself for the terminal. The public beam state indication information may be indicated by block SIB 1, high layer signaling or physical layer signaling.

[0140] Similarly, the common beam state indication information may be used to indicate at least one of the following information:

[0141] 1) The public beam state is valid;

[0142] 2) The effective time of the public beam state being in the effective state;

[0143] Specifically, the public beam state indication information may include timer parameter indication information, and the timer parameter indication information is used to indicate the effective time of the public beam state as a valid state. Further, the public beam state indication information may also include an offset time parameter, and the offset time parameter is used to indicate that the public beam state becomes effective after the offset time indicated by the offset time parameter.

[0144] 3) The public beam status is invalid.

[0145] The following provides multiple implementations of sending the common beam state indication information, for example:

[0146] a) The network side device sends the common beam state indication information carrying the common beam state information field, wherein different values ​​of the common beam state information field are used to indicate whether the common beam state is in a valid state.

[0147] b) The network side device sends common beam status indication information encrypted with a preset RNTI, wherein there is a predefined mapping relationship between the preset RNTI and the common beam status.

[0148] c) The network side device sends the common beam state indication information carrying an existing information field, wherein the existing information field is a field used to indicate other information other than the common beam state, and there is a predefined mapping relationship between the preset value of the existing information field and the common beam state.

[0149] The following describes the implementation of the beam determination method of the embodiment of the present invention on both the terminal and the network side. In conjunction with the accompanying drawings, several examples of applying the beam determination method of the embodiment of the present invention are further provided.

[0150] Example 1:

[0151] The base station sends a common beam status indication signaling. The indication signaling is configured through RRC signaling, and the signaling includes a timer parameter, as shown below:

[0152] Common_beam_state

[0153] {

[0154] DurationTimer

[0155] TimeOffset

[0156] }

[0157] Among them, the parameter DurationTimer indicates the effective time of the common beam state (used to indicate the duration), and TimeOffset indicates the offset time of the common beam state (used to determine the start time). The common beam state is triggered by MAC-CE or dynamic signaling in the NR system. For example, using the UE group Common DCI trigger, the terminal determines that it enters the effective state of the common beam state from the moment of "receiving DCI" + TimeOffset until DCI + TimeOffset + DurationTimer. Here, "receiving DCI" means the reception time of the UE group Common DCI.

[0158] At the same time, the system predefines that during the common beam state, all uplink and downlink channels (i.e., PDCCH, PDSCH, PUSCH, and PUCCH) are transmitted using the beam used by the CORESET with the smallest ID, that is, all uplink and downlink channels are transmitted using the beam of the PDCCH channel. For example, MAC-CE activates TCI state 3 as the beam used by the CORESET with the smallest ID, that is, PDCCH is transmitted using the beam corresponding to TCI state 3. In this way, starting from the moment DCI+TimeOffset is received, and within the time range of DCI+TimeOffset+DurationTimer, PDCCH, PDSCH, PUSCH, and PUCCH are all transmitted using the beam corresponding to TCI state 3.

[0159] In addition, the system may predefine that all uplink and downlink channels use a DCI in the UE-specific DCI, such as DCI format 0_1, and use the beam for transmission.

[0160] Example 2:

[0161] The base station sends a common beam status indication signaling. The indication signaling is configured through RRC signaling, and the signaling includes a timer parameter, as shown below:

[0162] Common_beam_state

[0163] {

[0164] DurationTimer

[0165] TimeOffset

[0166] Period

[0167] }

[0168] Among them, the parameter DurationTimer indicates the effective time (duration) of the common beam state, TimeOffset indicates the starting offset time of the common beam state, and Period indicates the period of the common beam state.

[0169] The system predefines the start time of SFN0 as the starting reference point of the common beam state. Thus, according to the above configuration, the terminal determines SFN0+TimeOffset as the start time of the common beam state, and lasts until the end of SFN0+TimeOffset+DurationTimer in the first cycle.

[0170] The second period of the common beam state is: starting from SFN0+TimeOffset+Period and ending at SFN0+TimeOffset+Period+DurationTimer, and so on.

[0171] During the validity period of each common beam state, similar to Example 1, the system predefines all uplink and downlink channels to use the beam of the PDCCH channel for transmission, which will not be described in detail here.

[0172] Example 3:

[0173] The base station side uses UE-group common DCI to indicate whether the terminal common beam state is valid. For example, DCI format 2-7 is defined, which contains a common beam state indication field. If the indication field indicates 'ON', it means that the common beam state is effective; if the indication field indicates 'OFF', it means that the common beam state is invalid. The terminal determines the current state based on the received DCI. Or,

[0174] The base station side uses UE-specific DCI, such as (DCI format0-0, DCI format 0-1, DCI format1-0, DCIformat1-1) to indicate whether the terminal common beam state is valid. When part or all of the information fields in the system predefined DCI are the first special value, it indicates that the common beam state is valid; when part or all of the information fields in the system predefined DCI are the second special value, it indicates that the common beam state is invalid.

[0175] For example, when the values ​​in the frequency domain resource allocation field and the time domain resource allocation field in the system predefined DCI format1-1 are all 0, it indicates that the common beam state is valid; when the values ​​are all 1, it indicates that the common beam state is invalid. The terminal determines the current state according to the received UE-specific DCI. Or,

[0176] The base station side uses UE-group common DCI to indicate whether the terminal common beam state is valid. This DCI is encrypted with different RNTIs and is used to indicate whether the common beam state is effective. For example, the system predefines Common-beam-RNTI1 and Common-beam-RNTI2. After DCI format 1-0 is encrypted with Common-beam-RNTI1, it indicates that the common beam state is valid; after DCI format 1-0 is encrypted with Common-beam-RNTI2, it indicates that the common beam state is invalid; the terminal determines the current state based on the received UE-specific DCI.

[0177] Example 4:

[0178] The system predefines that the common beam state takes effect after the base station completes the downlink beam scanning. For example, the base station triggers the transmission of aperiodic CSI-RS and requires the terminal to report the CSI-RS resource index (CRI). When the terminal completes the measurement of the aperiodic CSI-RS and reports the CRI, the terminal and the base station begin to enter the common beam effective state.

[0179] During the validity period of each common beam state, similar to Example 1, the system predefines all uplink and downlink channels to use the beam of the PDCCH channel for transmission, which will not be described in detail here.

[0180] The public beam failure can be determined by configuring a timer through high-layer signaling or physical layer signaling, as described in Example 1. It can also be determined by a certain event predefined by the system. For example, if the system predefines the base station to perform beam indication, the public beam state fails. The public beam state may fail after the base station indicates the beam direction of the uplink PUSCH through DCI format 0_1.

[0181] The above describes various methods of the embodiments of the present invention. The following further provides devices for implementing the above methods.
