[0022] Generally, the number of connections supported by traditional communication systems is limited and easy to implement.

[0023] Optionally, the communication system in the embodiment of the present application can be applied to a Carrier Aggregation (CA) scenario, a Dual Connectivity (DC) scenario, and even a Standalone (SA) deployment scenario.

[0024] The embodiments of the present application are not limited to a specific spectrum, for example, the embodiments of the present application may be applied to both licensed and unlicensed spectrum.

[0025] For illustrative purposes, a communication system 100 applied in an embodiment of the present application is shown in Fig. 1. The communication system 100 may include a network device 110, which may be a device capable of communicating with a terminal device 120 (also called a communication terminal or terminal). The network device 110 may provide communication coverage in a specific geographic area and communicate with the terminal device located within the coverage area.

[0026] FIG. 1 illustrates one network device and two terminal devices as an example, and alternatively, the communication system 100 may include multiple network devices, and each network device may include other quantities of terminal devices within its coverage range, and the embodiments of the present application are not limited thereto.

[0027] Optionally, the communication system 100 may further include other network entities, such as a network controller, a mobile management entity, etc., and the embodiments of the present application are not limited thereto.

[0029] It should be understood that the terms "system" and "network" herein can be used interchangeably. The term "and / or" herein is used only to describe the relation between related objects, and means that three relations can exist. For example, A and / or B can mean three situations: A exists alone, A and B exist simultaneously, and B exists alone. Also, the character " / " herein generally means that the related objects before and after are in an "or" relation.

[0030] In the embodiments of the present application, each embodiment is described with respect to a terminal device and a network device. The terminal device may be called a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a distant station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal device may be a station (ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a terminal device in a next-generation communication system, such as an NR network or a future evolved Public Land Mobile Network (PLMN) network. ) The present invention may also be applied to terminal devices in a mobile communication system.

[0031] By way of example and not of limitation, in the embodiments of the present application, the terminal device may further be a wearable device. The wearable device may also be called a wearable smart device, which is a collective term for wearable devices such as glasses, gloves, watches, clothing, and shoes that are developed by applying wearable technology to intelligently design daily wear. That is, a wearable device is a portable device that is directly worn on the body or integrated into the user's clothing or accessories. A wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include smart watches or smart glasses that are full-featured and large in size and can realize full or partial functions without relying on a smartphone, and various smart bracelets and smart jewelry for sign monitoring that focus only on certain types of application functions and require cooperation with other devices such as smartphones.

[0032] The network equipment may be equipment for communicating with a mobile device, and the network equipment may be an access point (AP) in a WLAN, a base station (BTS) in a GSM or CDMA, a base station (NodeB, NB) in a WCDMA, an evolved base station (eNB or eNodeB) in an LTE, a relay station or an access point, or a network equipment (gNB) in an in-vehicle device, a wearable device, and an NR network, or a future evolved PLMN network.

[0033] In an embodiment of the present application, a network device provides services to a cell, and a terminal device communicates with the network device via a transmission resource (such as a frequency domain resource or a spectrum resource) used in the cell, and the cell may be a cell corresponding to a network device (such as a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell, where the small cell may include a metro cell, a micro cell, a pico cell, a femto cell, etc., and these small cells have characteristics of small coverage and low transmission power and are suitable for providing high-speed data transmission services.

[0034] In NR Rel 16, PUSCH repetition is strengthened and some restrictions are relaxed. As shown in Figures 2 and 3, it should be understood that there may be one or more PUSCHs in each time slot, and the time domain resources in which the PUSCHs are located may be different. Figure 2 shows an inter-time slot PUSCH, and Figure 3 shows a situation in which there are multiple PUSCHs in one time slot. Since there are no restrictions on application scenarios, data can be scheduled immediately, thereby reducing the time delay of data transmission.

[0035] In FIG. 3, D represents a downlink symbol in a timeslot, F represents a flexible symbol in a timeslot, and U represents an uplink symbol in a timeslot.

[0036] When the restriction is relaxed, a situation occurs in which one PUSCH is split into two or more PUSCHs. As shown in Figure 2, a PUSCH during one time slot is split into two independent PUSCHs, i.e., it transmits an independent transport block (TB). As shown in Figure 3, when one PUSCH encounters a downlink resource and a flexible resource, it is automatically split, and the two split PUSCHs transmit independent TBs.

[0037] When a PUSCH repetition is divided, a PUSCH repetition with a short duration may be formed, but these PUSCH repetitions are too short to realize effective transmission. For these PUSCH repetitions with a short duration, as shown in Figure 4, there is a countermeasure for not transmitting the short PUSCH repetition, which results in resource waste, and as shown in Figure 5, there is a countermeasure for connecting the short PUSCH repetition with an adjacent PUSCH repetition to form a relatively long new PUSCH repetition, but in this case, the DMRSs are not matched, which interferes with the detection performance of the DMRS.

[0038] To address the above-mentioned problems, the present application proposes a method of combining PUSCH repetition cascading and discarding, and performs DMRS mapping and TB mapping according to PUSCH repetition resources and in consideration of the situation, which not only improves system efficiency and avoids resource waste, but also avoids DMRS and data collision and the impact on normal data demodulation.

[0039] The technical solution of the present application, which is designed in consideration of the above technical problems, will be described in detail below.

[0040] FIG. 6 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 6, the method 200 includes: S210, a terminal device determines a first channel obtained by combining at least two second channels, the first channel being mapped by at least one data TB; and S220 may include all or part of the step of the terminal device transmitting the at least one data TB on the first channel.

[0041] The first channel which is mapped by at least one data TB, the so-called combined channel, is mapped by a data TB.

[0042] Optionally, in the present embodiment, the channel includes an uplink channel and / or a downlink channel, i.e., the first channel may be an uplink channel or a downlink channel, and the second channel may be an uplink channel or a downlink channel.

[0043] In addition, the first channel and the second channel are of the same type, i.e., the first channel and the second channel are both downlink channels, or the first channel and the second channel are both uplink channels.

[0044] For example, the uplink channel is a PUSCH or a Physical Uplink Control Channel (PUCCH).

[0045] Further, for example, the downlink channel is a Physical Downlink Shared Channel (PDSCH) or a Physical Downlink Control Channel (PDCCH).

[0046] When the first channel is an uplink channel, S220 may specifically be a step of the terminal device transmitting the at least one data TB on the first channel, whereas when the first channel is a downlink channel, S220 may specifically be a step of the terminal device receiving the at least one data TB on the first channel.

[0047] It should be noted that in the embodiments of the present application, a two channel combination may be understood as a two channel cascade.

[0048] Optionally, in embodiments of the present application, at least one second channel of the at least two second channels is obtained by splitting a third channel.

[0049] For example, the at least one second channel is formed when a third channel is split between time slot boundaries.

[0050] Furthermore, for example, the at least one second channel is formed when the third channel is automatically split (divided).

[0051] In addition, the third channel and the second channel are of the same type, i.e., the third channel and the second channel are both downlink channels, or the third channel and the second channel are both uplink channels.

[0052] Optionally, in the embodiment of the present application, the third channel may be configured by the network device.

[0053] For example, the terminal device receives first setting information for setting at least one third channel, transmitted by the network device.

[0054] Optionally, the at least one third channel may be a third channel repetition.

[0055] For example, the third channel repetition number is four, that is, there are four third channels, and the four third channels are distributed consecutively in the time domain.

[0056] Alternatively, the network device may allocate resources for the PUSCH repetition by an uplink grant (UL grant).

[0057] Optionally, in the present embodiment, it can be configured whether the second channel is combinable, as well as whether the second channel is discardable.

[0058] For example, the terminal device receives first indication information sent by the network device for indicating whether the second channel can be combined and / or dropped.

[0059] Optionally, in embodiments of the present application, the second channel may be set by default to be combinable and discardable.

[0060] Optionally, if the second channel is combinable and / or discardable, the terminal device may: and / or A second rule determines whether to combine or discard the second channel.

[0061] The first rule is: At least one of the following rules is satisfied: a length of the second channel time domain is less than or equal to a first threshold; an equivalent code rate of data to be transmitted on the second channel is greater than or equal to k, where k is a positive number; and the second channel has data transmission resources.

[0062] The second rule is a rule as to whether or not there is an adjacent second channel for the second channel.

[0063] Optionally, the first threshold is preset, or the first threshold is set by the network device.

[0064] For example, k is 1 or 0.93.

[0065] It should be noted that the equivalent code rate can be used to determine the available data transmission resources and can also be used to determine the modulation mode and bits.

[0066] specifically, If at least one of the following conditions is satisfied: the length of the second channel time domain is less than or equal to a first threshold; the equivalent code rate of the data to be transmitted on the second channel is greater than or equal to k; and the second channel has no data transmission resources, the terminal device determines that the second channel satisfies the first rule.

[0067] Specifically, if there is an adjacent second channel for the second channel, the terminal device determines that the second channel satisfies the second rule.

[0068] Optionally, in the embodiment of the present application, the first rule and / or the second rule may be set by a network device through Radio Resource Control (RRC) signaling.

[0069] For example, for the first rule, the first threshold value may be from 1 symbol to 4 symbols.

[0070] Optionally, in the embodiment of the present application, the terminal device specifically includes: means for determining that the terminal device will not combine or discard the second channel if the second channel does not satisfy the first rule; and / or means for determining that the terminal device discards the second channel if the second channel satisfies the first rule but not the second rule; and / or means for determining that the terminal device combines the second channel if the second channel satisfies the first rule and satisfies the second rule; and / or If the second channel does not satisfy the first rule, the terminal device uses the means for transmitting data TB independently on the second channel to determine whether to combine or discard the second channel.

[0071] Optionally, in an embodiment of the present application, if the second channel is capable of being combined and / or discarded, the terminal device combines the second channel with its adjacent second channels.

[0072] Optionally, in an embodiment of the present application, the reference signal is mapped according to said first channel.

[0073] Optionally, in an embodiment of the present application, the reference signal is mapped according to said second channel.

[0074] Optionally, in an embodiment of the present application, the reference signal is mapped according to a third channel, which is a configured channel.

[0075] Optionally, the reference signal includes a front loaded Demodulation Reference Signal (DMRS) and / or an additional DMRS.

[0076] Optionally, in an embodiment of the present application, when the channel is a PUSCH repetition, the network device sends a PUSCH repetition parameter to the terminal device, and the terminal device can send uplink data according to the PUSCH repetition parameter.

[0077] Therefore, in an embodiment of the present application, the terminal equipment can transmit at least one data TB on a first channel obtained by combining at least two second channels, thereby improving system efficiency and avoiding resource waste.

[0078] In the following, the solution of the present application will be described in detail with reference to specific embodiments, taking as an example that the channel is a PUSCH and that a network device allocates PUSCH repetition resources for a terminal device.

[0079] Alternatively, as embodiment 1, The network equipment sets the number of PUSCH repetitions for the terminal equipment to four (four tertiary channels), and the time domain location of the first PUSCH repetition is the fifth symbol to the twelfth symbol of the nth time slot, and the subsequent PUSCH repetitions immediately follow the previous PUSCH repetition resource in the time domain, so the time domain resources of the four PUSCH repetitions (four tertiary channels) are shown in FIG. 7a. Also, as shown in FIG. 7b, because the second PUSCH repetition crosses a time slot boundary, the second PUSCH repetition is split into part A (two symbols) and part B (six symbols) (two tertiary channels) in the time domain, and the four PUSCH repetitions (four tertiary channels) are split into five PUSCH repetitions (five tertiary channels). As shown in Fig. 7c, assuming that the cascading decision threshold (ConcatenationThrethold) is 3 symbols, the part A is 2 symbols, which is smaller than the ConcatenationThrethold, so the part A is cascaded with the previous PUSCH repetition (forming a first channel), but the part B is 6 symbols, which is larger than the ConcatenationThrethold, so the part B is not cascaded with the next PUSCH repetition. As shown in Fig. 7c, the DMRS and TB are mapped according to the cascaded PUSCH repetition.

[0080] Therefore, in the first embodiment, the cascading operation improves the system efficiency and avoids the waste caused by discarding. In addition, by setting the threshold cascading, the cascading of short PUSCH repetitions can be realized, which not only improves the system efficiency, but also avoids the cascading of long PUSCH repetitions, thereby reducing the processing time delay or increasing the code rate. In addition, the length of PUSCH repetition A By having a skewed decision threshold, system efficiency is improved and resource waste due to discards is avoided.

[0081] Optionally, as embodiment 2, It can be seen that the network equipment sets the number of PUSCH repetitions for the terminal equipment to 4 (four tertiary channels), the time domain location of the first PUSCH repetition is from the 13th symbol of the nth time slot to the 6th symbol of the n+1th time slot, and the subsequent PUSCH repetitions immediately follow the previous PUSCH repetition resource in the time domain, so that the time domain resources of the four PUSCH repetitions (four tertiary channels) are as shown in Fig. 8a. Also, as shown in Fig. 8b, since the first PUSCH repetition and the fourth PUSCH repetition cross the time slot boundary, the first PUSCH repetition is split into part A (two symbols) and part B (six symbols) (two tertiary channels) in the time domain, the fourth PUSCH repetition is split into part C (six symbols) and part D (two symbols) (two tertiary channels) in the time domain, and the four PUSCH repetitions (four tertiary channels) are split into six PUSCH repetitions (six tertiary channels). As shown in Fig. 8c, assuming that the cascading decision threshold is 3 symbols, the part A is 2 symbols, which is smaller than the cascading decision threshold, but there is no PUSCH repetition that can be cascaded before it, so the part A is discarded, the part B is 6 symbols, which is larger than the cascading decision threshold, so the part B is not cascaded with the next PUSCH repetition, the part C is 6 symbols, which is larger than the cascading decision threshold, so the part C is not cascaded with the previous PUSCH repetition, and the part D is 2 symbols, which is smaller than the cascading decision threshold, but there is no PUSCH repetition that can be cascaded after it, so the part D is discarded. As shown in Fig. 8c, the DMRS and TB perform mapping according to the cascaded PUSCH repetition.

[0082] Therefore, in the second embodiment, the discard operation avoids interference caused by mismatch between the DMRS and data. ABy using the cascading decision threshold, the system efficiency is improved and the resource waste caused by discarding is avoided. Cascading is abandoned for PUSCH repetitions that do not satisfy the cascading condition, so that the resource waste is kept small and the interference between DMRS and data that affects normal data demodulation can be avoided.

[0083] Optionally, Figure 9 shows a comparison diagram of PUSCH repetitions of four UEs, where the PUSCH repetitions of the four UEs overlap in the time domain and the frequency domain, and the position of the PUSCH repetition in the time domain is shifted back by one. From Figure 9, it can be seen that after the PUSCH repetition cascading / discarding is performed according to the rules in the above embodiment 1 and embodiment 2, the collision problem between DMRS and data is eliminated.

[0084] Optionally, as embodiment 3, As shown in FIG. 10a, the network device sets the number of PUSCH repetitions for the terminal device to 4 (4 tertiary channels), and the time domain location of the first PUSCH repetition is from the 9th symbol of the nth time slot to the 2nd symbol of the n+1th time slot, and the subsequent PUSCH repetitions immediately follow the previous PUSCH repetition resource in the time domain, so that the time domain resources of the 4 PUSCH repetitions (4 tertiary channels) can be known. Also, as shown in FIG. 10b, since the first PUSCH repetition and the third PUSCH repetition cross the time slot boundary, the first PUSCH repetition is split into part A (6 symbols) and part B (2 symbols) (2 tertiary channels) in the time domain, the third PUSCH repetition is split into part C (4 symbols) and part D (4 symbols) (2 tertiary channels) in the time domain, and the 4 PUSCH repetitions (4 tertiary channels) are split into 6 PUSCH repetitions (6 tertiary channels). As shown in Fig. 10b, DMRS performs mapping according to the divided PUSCH repetition. As shown in Fig. 10c, the divided PUSCH repetition is cascaded with adjacent PUSCH repetition, specifically, since the part A does not have adjacent PUSCH repetition, the part A is an independent PUSCH repetition, the part B is cascaded with the next PUSCH repetition (forms the first channel), the part C is cascaded with the previous PUSCH repetition (forms the first channel), the part D is cascaded with the next PUSCH repetition (forms the first channel), and the cascaded PUSCH repetition is formed, and at the same time, one TB is mapped with one cascaded PUSCH repetition.

[0085] Therefore, in embodiment 3, the DMRS is inserted according to the divided PUSCH repetition, the DMRS between different PUSCH repetitions is ensured to be consistent, and the TB is mapped according to the cascaded PUSCH repetition, so that the occurrence of orphan symbols is avoided and the transmission efficiency is improved.

[0086] Optionally, as embodiment 4, As shown in FIG. 11A, the network device sets the number of PUSCH repetitions for the terminal device to four (four tertiary channels), and the time domain position of the first PUSCH repetition is from the third symbol of the n+1th time slot to the tenth symbol of the n+1th time slot, and the subsequent PUSCH repetitions immediately follow the previous PUSCH repetition resource in the time domain, so that the time domain resources of four PUSCH repetitions (four tertiary channels) can be known. Also, as shown in Fig. 11b, since the second PUSCH repetition and the fourth PUSCH repetition cross the time slot boundary, the second PUSCH repetition is split into part A (4 symbols) and part B (4 symbols) (two second channels) in the time domain, the fourth PUSCH repetition is split into part C (2 symbols) and part D (6 symbols) (two second channels) in the time domain, and the four PUSCH repetitions (four third channels) are split into six PUSCH repetitions (six second channels). As shown in Fig. 11b, the DMRS performs mapping according to the split PUSCH repetitions. As shown in Figure 11c, the split PUSCH repetitions are cascaded with adjacent PUSCH repetitions. Specifically, part A is cascaded with the previous PUSCH repetition (forming the first channel), part B is cascaded with the next PUSCH repetition (forming the first channel), part C is cascaded with the previous PUSCH repetition (forming the first channel), and part D has no adjacent PUSCH repetitions, so a cascaded PUSCH repetition is formed with part D as an independent PUSCH repetition, and at the same time, one TB is mapped with one cascaded PUSCH repetition.

[0087] Therefore, in the fourth embodiment, the DMRS mapping is based on the divided PUSCH repetition, so that the DMRS matching is always ensured, thereby improving the DMRS demodulation performance and the detection speed, and ensuring that the DMRS is always at the front end of the PUSCH repetition. Furthermore, the TB is mapped according to the cascaded PUSCH repetition, so that the occurrence of orphan symbols is avoided, and the transmission efficiency is improved.

[0088] Figure 12 shows a comparison diagram of the PUSCH repetition of four UEs, in which the PUSCH repetitions of the four UEs overlap in the time domain and the frequency domain, and the position of the PUSCH repetition in the time domain is shifted back by one. From Figure 12, it can be seen that after the PUSCH repetition cascading / discarding is performed according to the rules in the above embodiment 3 and embodiment 4, the collision problem between DMRS and data is eliminated.

[0089] Optionally, as embodiment 5, As shown in FIG. 13A, the network equipment sets the number of PUSCH repetitions for the terminal equipment to four (four tertiary channels), and the time domain position of the first PUSCH repetition is from the ninth symbol of the nth time slot to the second symbol of the n+1th time slot, and the subsequent PUSCH repetitions immediately follow the previous PUSCH repetition resource in the time domain, so that the time domain resources of four PUSCH repetitions (four tertiary channels) can be known, and DMRS mapping is performed according to the initial PUSCH repetition (pre-split PUSCH repetition), where the DMRS resource is configured by the network equipment. Also, because the first PUSCH repetition and the third PUSCH repetition cross a time slot boundary, the first PUSCH repetition is split in the time domain into part A (6 symbols) and part B (2 symbols) (2 second channels), the third PUSCH repetition is split in the time domain into part C (4 symbols) and part D (4 symbols) (2 second channels), and the four PUSCH repetitions (four tertiary channels) are split into six PUSCH repetitions (six second channels). As shown in FIG. 13b, the split PUSCH repetition is cascaded with adjacent PUSCH repetition. Specifically, since part A has no adjacent PUSCH repetition, part A is treated as an independent PUSCH repetition, part B is cascaded with the next PUSCH repetition (to form the first channel), part C is cascaded with the previous PUSCH repetition (to form the first channel), and part D is cascaded with the next PUSCH repetition (to form the first channel), and cascaded PUSCH repetition is formed, and at the same time, one TB is mapped with one cascaded PUSCH repetition.

[0090] Therefore, in the fifth embodiment, the DMRS mapping is based on the initial PUSCH repetition so that the DMRS consistency is always ensured, thereby ensuring the DMRS demodulation performance and reducing the DMRS overhead compared with the fourth embodiment. Furthermore, the TB is mapped according to the cascaded PUSCH repetition, thereby avoiding the occurrence of orphan symbols and improving the transmission efficiency.

[0091] Optionally, as Example 6, As shown in Fig. 14a, the network device sets the number of PUSCH repetitions for the terminal device to 4 (four third channels), and the time domain position of the first PUSCH repetition is from the third symbol of the n+1th time slot to the tenth symbol of the n+1th time slot, and the subsequent PUSCH repetitions immediately follow the previous PUSCH repetition resource in the time domain, so that the time domain resources of four PUSCH repetitions (four third channels) can be known, and DMRS mapping is performed according to the initial PUSCH repetition (pre-split PUSCH repetition), where the DMRS resource is set by the network device.As shown in Fig. 14b, the last split PUSCH repetition does not have a cascadable adjacent PUSCH repetition, so it is treated as an independent PUSCH repetition, and DMRS is also inserted into this independent PUSCH repetition. Also, because the second and fourth PUSCH repetitions cross a time slot boundary, the second PUSCH repetition is split in the time domain into part A (4 symbols) and part B (4 symbols) (two second channels), the fourth PUSCH repetition is split in the time domain into part C (2 symbols) and part D (6 symbols) (two second channels), and the four PUSCH repetitions (four tertiary channels) are split into six PUSCH repetitions (six second channels). As shown in FIG. 14b, the split PUSCH repetitions are cascaded with adjacent PUSCH repetitions. Specifically, part A is cascaded with the previous PUSCH repetition (forming the first channel), part B is cascaded with the next PUSCH repetition (forming the first channel), part C is cascaded with the previous PUSCH repetition (forming the first channel), and part D has no adjacent PUSCH repetitions, so a cascaded PUSCH repetition is formed with part D as an independent PUSCH repetition, and at the same time, one TB is mapped with one cascaded PUSCH repetition.

[0092] Therefore, in the sixth embodiment, the DMRS mapping is based on the initial PUSCH repetition so that the DMRS consistency is always ensured, thereby ensuring the DMRS demodulation performance and reducing the DMRS overhead compared with the fourth embodiment. Furthermore, the TB is mapped according to the cascaded PUSCH repetition, thereby avoiding the occurrence of orphan symbols and improving the transmission efficiency.
