[0002] In the Release 15 (R15) protocol, the configured grant physical uplink shared channel (CG-PUSCH) can be configured by the radio resource control (RRC). Here, for the configured grant physical uplink shared channel (CG-PUSCH) of type A, the cycle, offset, and specific time-frequency position of each time slot of the configured grant physical uplink shared channel (CG-PUSCH) are configured by the signaling of the radio resource control (RRC) layer. For the configured grant physical uplink shared channel (CG-PUSCH) of type B, the cycle of the configured grant physical uplink shared channel (CG-PUSCH) is configured by the signaling of the radio resource control (RRC) layer, and the offset and specific time-frequency position of each time slot are indicated by activating the downlink control information (DCI).

[0003] The configuration of the set of physical uplink shared channels (CG-PUSCH) of the configured grant is configured by radio resource control (RRC) signaling, or the transmission beam is indicated by downlink control information (DCI). That is, each physical uplink shared channel (PUSCH, Physical Uplink Shared Channel) in the set of physical uplink shared channels (CG-PUSCH) of the configured grant is transmitted using this transmission beam. Here, since the direction of this transmission beam is fixed, if there is interference in this direction, there is interference when the terminal transmits data using this transmission beam for each physical uplink shared channel, which affects the transmission of data.

[0031] Referring to Figure 1, it shows a schematic block diagram of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include several user devices 110 and several base stations 120.

Or, the base station 120 may be a base station (gNB) of a centralized distributed architecture used in a 5G system. When the base station 120 uses a centralized distributed architecture, it usually includes a central unit (CU) and at least two distributed units (DU). The centralized unit is provided with a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer protocol stack, and the distributed units are provided with a Physical (PHY) layer protocol stack, and the embodiments of the present disclosure do not limit the specific implementation of the base station 120.

[0035] The base station 120 and the user device 110 can establish a wireless connection via a wireless air interface. In different embodiments, the wireless air interface may be a wireless air interface based on a fourth generation mobile communication network technology (4G) standard, or the wireless air interface may be a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface may be a new air interface, or the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.

[0037] Here, the user equipment can be considered as a terminal device in the following embodiments.

[0038] In some embodiments, the wireless communication system may further include a network management device 130 .

[0039] Some base stations 120 are respectively connected to a network management device 130. Here, the network management device 130 may be a core network device in a wireless communication system, for example, the network management device 130 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC) network. Or the network management device may be another core network device, for example, a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The implementation form of the network management device 130 is not limited in the embodiment of the present disclosure.

[0040] To facilitate understanding of any embodiment of the present disclosure, a data transmission scenario will be first described by one embodiment.

[0041] In the Release 16 (R16) New Radio Unlicensed Spectrum (NR-U) standard design, the configured grant physical uplink shared channel (CG-PUSCH) design adds an expansion content to N timeslots compared to the configured grant physical uplink shared channel (CG-PUSCH) design in the Release 15 (R15) protocol, where N is a positive integer greater than 1. For example, N=4. Here, the expansion of N timeslots is not for repetition but for transmitting different uplink data in consecutive N timeslots.

[0042] As shown in Figure 2, the shaded portion indicates the configured grant physical uplink shared channel (CG-PUSCH), and the shaded portion has the same symbol position in each time slot. In one embodiment, the shaded portion may occupy the entire time slot. In Figure 2, the configuration cycle of the configured grant physical uplink shared channel (CG-PUSCH) is 10 time slots, and each configuration cycle has 4 time slots for data transmission on the configured grant physical uplink shared channel (CG-PUSCH).

[0043] In one embodiment, in an unlicensed spectrum, when a terminal wants to transmit uplink data, the terminal must first perform channel monitoring, i.e., clear channel assessment (CCA). Until the CCA detection is successful (i.e., the interference value of the detected channel is below a threshold), the terminal cannot transmit uplink data (i.e., ask first, tell first). If the terminal has multiple transmission beams, the beam on which the terminal performs channel detection must be the same as the transmission beam on which the terminal transmits the uplink data. Because the reception effects on interference and noise in different spatial directions caused by different transmission beams of the terminal are different, the interference values ​​of the signals detected by the terminal in different beams are also different.

[0044] As shown in FIG. 3, this embodiment provides a data transmission method, which is applied to a terminal, and includes the following steps 31 to 32.

[0045] In step 31, beam instruction information is received, where the beam instruction information indicates multiple transmission beams for a Physical Uplink Shared Channel (CG-PUSCH) of the configured grant.

[0046] In one embodiment, the terminal may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device.

[0047] In one embodiment, the beam direction information may indicate at least two transmit beams. For example, the beam direction information may indicate two beams, three beams, or five beams.

[0048] In one embodiment, the beam indication information is information including identifiers of multiple transmission beams determined by the base station for the terminal to transmit data on a configured grant physical uplink shared channel (CG-PUSCH).

[0049] In one embodiment, the beam indication information may include a sounding reference signal resource indication (SRI) value indicated by a sounding reference signal resource indication (SRI, srs-ResourceIndicator).

[0050] In one embodiment, different sounding reference signal resource indication (SRI) values ​​are associated with different transmit beams, e.g., a first sounding reference signal resource indication (SRI) value is associated with a first transmit beam and a second sounding reference signal resource indication (SRI) value is associated with a second transmit beam.

[0051] In one embodiment, one sounding reference signal resource indication (SRI) value is associated with one transmission beam. The beam indication information may include multiple sounding reference signal resource indication (SRI) values. In this way, multiple transmission beams can be determined after the sounding reference signal resource indication (SRI) values ​​are received.

[0052] In one embodiment, the transmit beam is selected by a terminal for uplink data transmission on a configured grant physical uplink shared channel (CG-PUSCH).

[0053] In one embodiment, the transmission beam may be a beam for transmitting uplink data on a configured grant physical uplink shared channel (CG-PUSCH) recommended or proposed by the base station to the terminal.

[0054] In one embodiment, a beam for transmitting uplink data on a configured grant physical uplink shared channel (CG-PUSCH) recommended or proposed by a base station to a terminal transmits data with a strength value of an interference signal that is less than a set threshold value, and thus the terminal performs reliable uplink data transmission using the beam.

[0055] In one embodiment, the base station is an interface device of a terminal access network. The base station may be various types of base stations, such as a 3G base station, a 4G base station, a 5G base station or other evolved base stations.

[0056] In one embodiment, a configured grant physical uplink shared channel (CG-PUSCH) may be configured with licensed or unlicensed spectrum.

[0057] In one embodiment, referring to FIG. 4, the physical uplink shared channels (CG-PUSCHs) of the configured grant in one configuration cycle may be four, namely, CG-PUSCH1, CG-PUSCH2, CG-PUSCH3, and CG-PUSCH4.

[0058] Here, one configured grant physical uplink shared channel (CG-PUSCH) can occupy all or part of the symbols of one timeslot, for example, CG-PUSCH1 can occupy all symbols of the 0th timeslot, or CG-PUSCH1 can occupy only the 3rd to 4th symbols of the 0th timeslot.

[0059] In one embodiment, the terminal can select some or all of the transmission beams from among the multiple transmission beams indicated by the beam indication information to transmit uplink data.

[0060] In one embodiment, different transmit beams have spatially different transmit angles and sector ranges.

[0061] In one embodiment, the angle between the different transmit beams is less than a set angle threshold.

[0062] In one embodiment, the spatial sector coverage of multiple transmit beams may be in the same plane.

[0063] In one embodiment, the spatial sector coverage of multiple transmit beams may occupy a three-dimensional space.

[0064] In one embodiment, if the physical uplink shared channel (CG-PUSCH) of the configured grant is a dedicated channel allocated to a specific terminal, the beam indication information may be transmitted by radio resource control (RRC) signaling.

[0065] In step 32, data is transmitted on a configured grant physical uplink shared channel (CG-PUSCH) using multiple transmit beams.

[0066] In one embodiment, a terminal may transmit the same uplink data using different transmit beams.

[0067] In one embodiment, the beam indication information indicates four transmission beams, namely, transmission beam 1, transmission beam 2, transmission beam 3, and transmission beam 4. The physical uplink shared channels (CG-PUSCH) of the configured grant in one configuration cycle may be four, namely, CG-PUSCH1, CG-PUSCH2, CG-PUSCH3, and CG-PUSCH4.

[0068] Referring again to FIG. 4, in one embodiment, CG-PUSCH1 may transmit uplink data using transmission beam 1, CG-PUSCH2 may transmit uplink data using transmission beam 2, CG-PUSCH3 may transmit uplink data using transmission beam 3, and CG-PUSCH4 may transmit uplink data using transmission beam 4.

[0069] In another embodiment, CG-PUSCH1 and CG-PUSCH3 may transmit uplink data using transmission beam 1, and CG-PUSCH2 and CG-PUSCH4 may transmit uplink data using transmission beam 2.

[0070] In the embodiment of the present disclosure, data can be transmitted on the configured grant physical uplink shared channel (CG-PUSCH) using multiple transmission beams based on multiple transmission beams instructed by the beam instruction information. Since different transmission beams may have different transmission directions in space, interference received in different directions in space is different. Compared with transmitting data on the configured grant physical uplink shared channel (CG-PUSCH) using the same transmission beam, transmitting data on the configured grant physical uplink shared channel (CG-PUSCH) using multiple transmission beams can improve interference resistance of data transmission and increase reliability of data transmission.

[0071] As shown in FIG. 5, this embodiment provides a data transmission method, in which in step 31, the step of receiving beam instruction information includes the following step 51:

[0072] In step 51, the transmitted beam indication information is received by Radio Resource Control (RRC) signaling, or the transmitted beam indication information is received by physical downlink control information (DCI).

[0073] In one embodiment, the radio resource control (RRC) signaling may include a radio resource control (RRC) connection reconfiguration (RRCConnectionReconfiguration) signaling including beam indication information, and the terminal receives the transmitted beam indication information through the radio resource control (RRC) connection reconfiguration (RRCConnectionReconfiguration) signaling. In this manner, the beam indication information is included in the existing radio resource control (RRC) signaling, thereby realizing multiplexing of the radio resource control (RRC) signaling and improving compatibility of the signaling.

[0074] In one embodiment, the beam instruction information may be included in downlink control information (DCI) for scheduling a physical uplink shared channel (CG-PUSCH) of the configured grant.

[0075] For example, the downlink control information (DCI) includes a sounding reference signal resource indication (SRI) value indicated by a sounding reference signal resource indication (SRI, srs-ResourceIndicator).

[0076] In one embodiment, different sounding reference signal resource indication (SRI) values ​​are associated with different beams. One downlink control information (DCI) may contain multiple sounding reference signal resource indication (SRI) values.

[0077] In one embodiment, the DCI is an activation DCI for activating a configured grant physical uplink shared channel (CG-PUSCH) for data transmission.

[0078] In one embodiment, the activation downlink control information (DCI) further indicates a time slot offset amount in each configured grant physical uplink shared channel (CG-PUSCH) configuration cycle and a specific time-frequency position to be occupied by each time slot of the configured grant physical uplink shared channel (CG-PUSCH).

[0079] Here, by including downlink beam instruction information in the existing activation downlink control information (DCI), multiplexing of the activation downlink control information (DCI) is realized, and compatibility of the activation downlink control information (DCI) is improved.

[0080] As shown in FIG. 6 , this embodiment provides a data transmission method, where in step 32, the step of transmitting data on a configured grant physical uplink shared channel (CG-PUSCH) using multiple transmission beams includes the following step 61:

[0081] In step 61, data is transmitted using different transmission beams on the configured grant physical uplink shared channel (CG-PUSCH) in different time units within one configuration cycle of the configured grant physical uplink shared channel (CG-PUSCH).

[0082] In one embodiment, one constituent cycle can include multiple time units, which may be one symbol or multiple consecutive symbols, and which may be one time slot or multiple consecutive time slots.

[0083] In one embodiment, the multiple transmission beams include transmission beam 1, transmission beam 2, transmission beam 3, transmission beam 4, and transmission beam 5. One configuration cycle includes 10 time units, and four consecutive time units in the configuration cycle are configured to the configured grant physical uplink shared channel (CG-PUSCH), and the four time units are time unit 1, time unit 2, time unit 3, and time unit 4, respectively. The terminal can arbitrarily select four transmission beams from the multiple transmission beams so as to transmit data on the configured grant physical uplink shared channel (CG-PUSCH) in the four time units. In one embodiment, the terminal selects a total of four transmission beams, transmission beam 1, transmission beam 2, transmission beam 4, and transmission beam 5. Here, in time unit 1, data is transmitted using transmission beam 1 on the configured grant physical uplink shared channel (CG-PUSCH), in time unit 2, data is transmitted using transmission beam 2 on the configured grant physical uplink shared channel (CG-PUSCH), in time unit 3, data is transmitted using transmission beam 4 on the configured grant physical uplink shared channel (CG-PUSCH), and in time unit 4, data is transmitted using transmission beam 5 on the configured grant physical uplink shared channel (CG-PUSCH).

[0084] As shown in FIG. 7, this embodiment provides a data transmission method, in which in step 61, the step of transmitting data using different transmission beams on a configured grant physical uplink shared channel (CG-PUSCH) in different time units within one configuration cycle of the configured grant physical uplink shared channel (CG-PUSCH) includes the following step 71:

[0085] In step 71, data is transmitted using different transmission beams by polling on the configured grant physical uplink shared channel (CG-PUSCH) at different time units within one configuration cycle of the configured grant physical uplink shared channel (CG-PUSCH).

[0086] In one embodiment, polling to transmit data using different transmit beams may include transmitting data using each transmit beam of the plurality of transmit beams in a cyclical sequence.

[0087] In one embodiment, the multiple transmit beams include transmit beam 1 and transmit beam 2. One configuration cycle includes 10 time units. Four consecutive time units in each configuration cycle are configured in a configured grant physical uplink shared channel (CG-PUSCH). The four time units are time unit 1, time unit 2, time unit 3, and time unit 4, respectively. In the four time units, data can be transmitted using transmit beam 1 and transmit beam 2 in the configured grant physical uplink shared channel (CG-PUSCH). In one embodiment, in time unit 1, data is transmitted using transmit beam 1 in the configured grant physical uplink shared channel CG-PUSCH1, in time unit 2, data is transmitted using transmit beam 2 in CG-PUSCH2, in time unit 3, data is transmitted using transmit beam 1 in CG-PUSCH3, and in time unit 4, data is transmitted using transmit beam 2 in CG-PUSCH4.

[0088] In one embodiment, the multiple transmit beams include transmit beam 1, transmit beam 2, transmit beam 3, and transmit beam 4. One configuration cycle includes 10 time units, and four consecutive time units in each configuration cycle are configured in the configured grant physical uplink shared channel (CG-PUSCH). The four time units are time unit 1, time unit 2, time unit 3, and time unit 4, respectively. In the four time units, data can be transmitted in the configured grant physical uplink shared channel (CG-PUSCH) using transmit beam 1, transmit beam 2, transmit beam 3, and transmit beam 4. In one embodiment, in time unit 1, data is transmitted in CG-PUSCH 1 using transmit beam 1, in time unit 2, data is transmitted in CG-PUSCH 2 using transmit beam 2, in time unit 3, data is transmitted in CG-PUSCH 3 using transmit beam 3, and in time unit 4, data is transmitted in CG-PUSCH 4 using transmit beam 4.
