Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to Chinese Patent Application No. 202110506650.3 filed in China on May 10, 2021, the entire contents of which are incorporated herein by reference. The present application relates to the field of communications technology, and in particular to a method, apparatus, terminal and network side equipment for determining an uplink transmission time window. [Background technology]

[0002] Related technology introduces the function of Demodulation Reference Signal (DMRS) bundling, which means that power stability and phase continuity need to be maintained within a certain time window between multiple uplink transmissions, so that the network can perform joint channel estimation based on multiple uplink transmissions in this time window to improve the receiving performance.

[0003] However, due to UE capability limitations or the Time Division Duplexing (TDD) frame structure or the existence of some uplink unavailable slots, the length of the time window may exceed the range in which the UE can guarantee power stability and phase continuity. In addition, there may be unavailable slots for downlink transmission or relatively many uplink transmissions among multiple transmissions in the time window, which increases the demand for UE capability and thus makes it impossible to meet the requirements for power stability and phase continuity. For example, in a Time Division Duplexing (TDD) frame structure, there are relatively many downlink (DL) slots among uplink (UL) slots, and some high priority transmissions may cancel the current uplink transmission, so that the requirements for power stability and phase continuity cannot be guaranteed.

[0020] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the techniques described may be used in the above-mentioned systems and radio technologies, or in other systems and radio technologies. Although the following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in most of the description below, these techniques may be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0021] FIG. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc., and the wearable device includes a smart watch, a bracelet, an earphone, a pair of glasses, etc. It should be noted that the specific type of the terminal 11 in the embodiment of the present application is not limited. The network side device 12 may be a base station or a core network.Here, the base station may be referred to as a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a wireless local area network (WLAN) access point, a wireless communication technology (WiFi) node, a transmitting receiving point (TRP), or any other suitable term in the art, and as long as the same technical effect is achieved, the base station is not limited to a specific technical term. It should be explained that in the embodiments of the present application, only a base station in a New Radio (NR) system is taken as an example, but the specific type of the base station is not limited, and the core network equipment may be a location management equipment, such as a location management function (LMF, E-SLMC), etc.

[0022] A User Equipment (UE) can maintain power and phase continuity during transmission of multiple Physical Uplink Shared Channels (PUSCHs) within a certain time window, and thus, when receiving multiple PUSCHs, the network can obtain channel information for other PUSCH transmissions based on a Demodulation Reference Signal (DMRS) of one of the PUSCHs, and can perform joint channel estimation using the DMRSs in the multiple PUSCHs to improve reception performance, and this technique is called DMRS bundling. The time window is called a bundling window or a time domain window.

[0023] These multiple PUSCHs may be repeated transmissions of the same transport block, may be different transport blocks, or may be transmissions over multiple slots of the same transport block (TB processing over multiple-slots). These multiple PUSCHs may be transmitted in the same slot or in different slots.

[0024] The transmissions may be discontinuous, i.e., spaced apart by X symbols or slots, and the terminal can achieve maintaining constant power and phase continuity between the discontinuous transmissions when it does not need to meet an off-power requirement. The off-power requirement is an indication requirement of whether the radiation function can exceed a preset threshold when the terminal turns off the transmitter. Not needing to meet this requirement means that the terminal does not need to turn off the transmitter when not transmitting a signal, thereby maintaining constant power and phase continuity between the discontinuous transmissions.

[0025] The above scheme is also applied to multiple Physical Uplink Control Channel (PUCCH) transmissions to optimize DMRS bundling.

[0026] In the DMRS bundling technique, a UE can estimate the channel of multiple uplink transmissions in a certain time window based on the DMRS of one of the transmissions. In addition to satisfying certain transmission power and phase continuity, the UE also needs to satisfy some additional conditions: The transmission power does not change between multiple transmissions; and The number of radio bearers (RBs) allocated in the frequency domain between multiple transmissions does not change; The gap between two uplink transmissions does not exceed X symbols or slots; No frequency switching between the two uplink transmissions; not scheduling a downlink transmission between two uplink transmissions; and using the same modulation scheme among the multiple transmissions.

[0027] A method is needed to dynamically determine or divide the time window according to the actual transmission process, which can ensure a larger number of continuously available uplink transmission occasions in the actual time window, thereby ensuring that the requirements of power stability and phase continuity can be met in the actual time window of transmission, and the network can improve the receiving performance through joint channel estimation, and further improve the coverage capability.

[0028] An embodiment of the present application provides a method for determining an uplink transmission time window performed by a terminal, as shown in FIG. 2, including:

[0029] Step 101, obtain a first instruction; Step 102: determining a first time window between one or more uplink transmissions according to the first indication and a first rule, the first time window satisfying a first transmission characteristic.

[0030] Here, the first time window is the actual time window.

[0031] In the embodiment of the present application, the terminal determines a first time window between one or more uplink transmissions according to the first instruction and the first rule, which satisfies a first transmission characteristic, and the first time window is an actual time window, thus the nominal time window can be subdivided according to the actual transmission process or determined according to the actual transmission process to obtain an actual time window, which can ensure a relatively large number of continuously available uplink transmission occasions within the actual time window, thereby ensuring that the conditions of power stability and phase continuity can be met within the actual time window of transmission, and the network can improve the receiving performance through joint channel estimation, and further improve the coverage capability.

[0032] In some embodiments, obtaining the first instruction includes: Obtaining the first predefined instruction (e.g., the first instruction implies that the nominal time window is equal to a number of slots or symbols corresponding to repetitions); obtaining the first preconfigured instructions; obtaining said first indication configured by a Media Access Control (MAC) control unit (CE); obtaining the first indication configured by a Radio Resource Control (RRC) message; and obtaining the first indication constituted by Downlink Control Information (DCI).

[0033] In some embodiments, the first instruction comprises: a size of the second time window (the second time window is a nominal window, the size of the nominal time window being a set of consecutive slots and / or a set of symbols and / or a set of repetitions); A start time of a second time window; and an end time of the second time window; and and a repetition count N (N is a positive integer).

[0034] In some embodiments, the first rule is: Dividing a time domain length corresponding to the uplink transmission into one or more second time windows according to a size of the second time window, the size of the second time window being defined in units of a set of slots, a set of symbols, and / or a set of repetitions; If the number of symbols or slots or repetitions occupied by a nominal time window is not equal to 0, then a nominal time window consists of one or more real time windows, and a second time window is There are downlink transmission slots and / or symbols; and the number of consecutive unusable symbols in the uplink transmission is greater than X, where X is a predefined or preconfigured threshold used to limit the maximum number of non-contiguous transmission symbols that satisfies the first transmission characteristic; an uplink transmission on one of the uplink transmissions is terminated or canceled by a transmission of higher priority; and A number of consecutive available slots or symbols of uplink transmission exceeds a terminal capability, the terminal capability indicating a maximum time corresponding to which the terminal can maintain a transmission that satisfies a first transmission characteristic; When frequency hopping is enabled, the number of consecutive available slots or symbols of uplink transmission exceeds a frequency hopping interval in the time domain, and the frequency hopping interval is the number of symbols occupied in the time domain of one hop or a corresponding time interval; and dividing the second time window into one or more first time windows when the second time window satisfies at least one first condition: the second time window consists of consecutive slots, or consecutive symbols, or consecutive repeated transmissions, or available uplink slots, and the available uplink slots are semi-statically or dynamically configured slots used for the uplink transmission.

[0035] In some embodiments, if the nominal time window does not encounter a situation that requires a subdivision or decision, the nominal time window is the actual time window.

[0036] In some embodiments, the first rule is: determining a start time of the first time window by adopting a first manner in which a start time of a first first time window is a start time of the second time window, and a start time of another first time window is a first orthogonal frequency division multiplexing (OFDM) symbol of a slot in which a first actually available uplink transmission is located after an end time of a previous first time window, or a first OFDM symbol of a first actually available uplink transmission after an end time of a previous first time window; and determining an end time of the first time window by adopting a second manner in which an end time of a last first time window is an end time of the second time window, and an end time of another first time window is a time after a first time interval has elapsed from a start time of a current first time window, and the first time interval is: The size of the second time window; and a maximum time corresponding to which the terminal can maintain a transmission that satisfies the first transmission characteristic; If frequency hopping is enabled, a frequency hopping interval in the time domain determined based on the configuration; and a time interval between a start time of a current first time window and a first OFDM symbol of a first downlink transmission slot or symbol after the start time; a time interval between a start time of a current first time window and a first OFDM symbol of an uplink unusable resource that satisfies a second condition after the start time, the second condition being that a number of consecutive unusable symbols of an uplink transmission is greater than X, where X is a predefined or preconfigured threshold value that is used to limit a maximum number of non-continuous transmission symbols that satisfies a first transmission characteristic; a minimum value of at least one of a time interval between a start time of a current first time window and a first OFDM symbol of a first terminated or canceled uplink transmission after the start time; The first time window consists of a set of slots or symbols or repeated transmissions that are actually available for the uplink transmission, and the set of slots or symbols or repeated transmissions that are actually available is semi-statically or dynamically configured.

[0037] In some embodiments, an actual time window for uplink transmission determined by the first indication and the first rule elapses and the UE does not need to satisfy off-power requirements within the actual time window.

[0038] In some embodiments, when frequency hopping is enabled, each of the second time windows corresponds to a new hop, and the frequency hopping location is determined by a first number, the first number being: The number of the second time window; and the number of the first slot or the number of the last slot in which the second time window is located; a first slot number actually used for uplink transmission in the second time window; and and the first repeated transmission number actually used for uplink transmission in the second time window.

[0039] In some embodiments, when frequency hopping is enabled, each of the first time windows corresponds to a new hop, and the frequency hopping location is determined by a second number, the second number being: The number of the first time window; and the number of a second time window in which the first time window is located; the number of the first slot or the number of the last slot in which the first time window is located; and at least one of the number of the first repetition transmission in which the first time window is located and the number of the last repetition transmission in which the first time window is located. Here, the repetition transmission includes a nominal repetition transmission and an actual repetition transmission.

[0040] In some embodiments, two consecutive first time windows can maintain or use the same frequency hopping position if they remain consecutive in the time domain or are spaced apart by no more than X symbols.

[0045] In some embodiments, the end time of the second time window is: the end time of the last OFDM symbol of the currently scheduled transmission; Relative to the start time of the second time window, M (M is a positive integer) second time windows are U The end time after the time has elapsed, and an end time after K (K is a positive integer) first time windows have elapsed relative to the start time of the second time window; and an end time after a preset time length has elapsed from the start time of the second time window.

[0049] In the above embodiments, the multiple uplink transmissions may include multiple different uplink physical channels or signals, or multiple transmissions of a single uplink physical channel, such as multiple repetitions in a repetition transmission, or multiple slots in a TBoMS transmission.

[0050] An embodiment of the present application provides a method for determining an uplink transmission time window performed by a network side equipment, as shown in FIG. 3, including:

[0051] Step 201: sending a first instruction to a terminal, the first instruction being used to determine a first time window between one or more uplink transmissions, satisfying a first transmission characteristic.

[0052] In some embodiments, transmitting the first instruction comprises: sending said first indication to said terminal via a Media Access Control (MAC) control unit (CE); sending the first indication to the terminal via a radio resource control (RRC) message; and transmitting the first instruction to the terminal via downlink control information DCI.

[0053] In some embodiments, the first instruction comprises: The size of the second time window; and A start time of a second time window; and an end time of the second time window; and and a repetition count N (N is a positive integer).

[0054] In the above embodiment, the DCI is a DCI for dynamically scheduling a physical uplink shared channel (PUSCH), or a DCI for activating a configuration permission type 2 PUSCH.

[0055] In some embodiments, the first instruction is located in a newly added first instruction field in the DCI, or transmission A power control command field (TPC command); A time domain resource assignment (TDRA) field; Precoding information and number of layers field, The antenna ports are located in at least one of the designated fields.

[0056] In some embodiments, the first transmission characteristic, during one or more uplink transmissions, comprises: The modulation method is the same, The frequency position is the same, The bandwidth is the same, The transmission power is the same, The transmission power difference value is smaller than a preset threshold value; and The beam (Spatial Tx Filter) is the same, The Transmit Precoding Matrix Indication (TPMI) is the same, The waveform (DFT-s-OFDM or CP-OFDM) is the same, For PUSCH, it is the same transmission block (TB), The uplink control information UCI is the same for the physical uplink control channel PUCCH; and . the same PUCCH format for the physical uplink control channel (PUCCH).

[0057] In the above embodiment, being the same includes not only being exactly the same, but also being relatively small in difference between the two.

[0058] In some embodiments, the uplink transmission comprises: The PUSCH repetition type includes at least one of a PUSCH repetition type A, a PUSCH repetition type B, a PUSCH over multi-slot transmission block TBoMS, a PUCCH, and a sounding reference signal SRS.

[0059] In the above embodiments, the multiple uplink transmissions may include multiple different uplink physical channels or signals, or multiple transmissions of a single uplink physical channel, such as multiple repetitions in a repetition transmission, or multiple slots in a TBoMS transmission.

[0060] The following further introduces the technical solution of this application in conjunction with drawings and specific embodiments.

[0061] In one embodiment, for a certain uplink repetition transmission type A (PUSCH repetition type A), if the configured repetition number is 8, the size of the nominal time window is determined according to a predefined manner to be the repetition number and correspond to 8 slots. Meanwhile, the maximum time during which the UE can maintain the transmission satisfying the first transmission characteristic at this time is 4 slots, and for an FDD system, the actual time window determined according to the first rule is as shown in Figure 4. When the frequency hopping interval is 4 slots or more, the corresponding frequency hopping pattern is as shown in Figure 5.

[0062] For a TDD system, assuming that the semi-static frame structure is "DDDSUDDSUU", the actual time window determined based on the first rule is as shown in Figure 6, and the corresponding frequency hopping pattern is as shown in Figure 7, where 1st hop is the first hop, 2nd hop is the second hop, and the first hop and the second hop are located at different frequency domain positions.

[0063] In another embodiment, for a certain uplink repetition transmission type A (PUSCH repetition type A), if the configured repetition count is 16, the first instruction determines the size of the nominal time window to be 8 slots, while the maximum time that the UE can maintain the transmission satisfying the first transmission characteristic at this time is 4 slots, and then, for an FDD system, the actual time window determined based on the first rule is as shown in Figure 8, and when the configured frequency hopping interval is 4 slots at this time, the frequency hopping pattern is as shown in Figure 9.

[0064] Considering that when frequency hopping is enabled, the same frequency hopping position can be used for an actual window in which the interval between two consecutive or non-consecutive symbols is smaller than X, the corresponding frequency hopping pattern is as shown in FIG. 10.

[0065] For a TDD system, some slots become unavailable due to SFI / CI during this repeated transmission, and the actual time window determined based on the first rule is as shown in Figure 11. If the frequency hopping interval configured at this time is 1 slot, the frequency hopping pattern is as shown in Figure 12.

[0066] Furthermore, when frequency hopping is enabled, considering that the same frequency hopping position can be used for an actual window in which the interval between two consecutive or non-consecutive symbols is smaller than X, the corresponding frequency hopping pattern is as shown in FIG. 13, and in this case, if the configured frequency hopping interval is 2 slots, the frequency hopping pattern is as shown in FIG. 14.

[0067] It should be noted that in the method for determining an uplink transmission time window according to the embodiment of the present application, the execution body may be an apparatus for determining an uplink transmission time window, or a module for executing and loading the method for determining an uplink transmission time window in the apparatus for determining an uplink transmission time window. In the embodiment of the present application, the method for determining an uplink transmission time window according to the embodiment of the present application is described by taking the apparatus for determining an uplink transmission time window as an example for executing and loading the method for determining an uplink transmission time window.

[0068] The embodiment of the present application provides an apparatus for determining an uplink transmission time window for use in a terminal 300, as shown in FIG. 15 , the apparatus includes: an acquisition module 310 for acquiring a first instruction; A processing module 320 for determining, based on the first indication and a first rule, a first time window between one or more uplink transmissions that satisfies a first transmission characteristic.

[0069] Here, the first time window is the actual time window.

[0070] In the embodiment of the present application, the terminal determines a first time window between one or more uplink transmissions according to the first instruction and the first rule, which satisfies a first transmission characteristic, and the first time window is an actual time window. In this way, the nominal time window can be subdivided according to the actual transmission process, or determined according to the actual transmission process to obtain an actual time window, which can ensure a larger number of continuously available uplink transmission occasions in the actual time window. This ensures that the conditions of power stability and phase continuity can be met in the actual time window of transmission, and the network can improve the receiving performance through joint channel estimation, and further improve the coverage capability.
