Description

Technical Field

[0002] In New Radio (NR) Release (Rel)-16, if uplink channels with different priorities overlap, the terminal device discards the low-priority uplink channel and only transmits the high-priority channel. The advantage of doing so is that the transmission delay requirement and reliability of the high-priority channel are guaranteed. However, considering that in practical applications, low-priority channels are usually used to transmit enhanced mobile broadband (eMBB) services with a large amount of data, discarding low-priority channels will cause a large amount of data retransmission, thereby reducing the system transmission efficiency. Therefore, in the design of NR Rel-17, it is considered to support multiplexing transmission of different priority information (i.e., information carried by different priority channels) to reduce the probability of discarding low-priority information and improve system efficiency. However, when supporting multiplexing transmission of different priority information, how to ensure the delay requirement and reliability requirement of high-priority information is an urgent problem to be solved.

The embodiments of this application do not limit this.

[0037] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term " / and" in this article is merely a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0038] Embodiments of the present application describe various embodiments in combination with a terminal device and a network device, where: The terminal device may also be referred to as a User Equipment (UE), access terminal, user unit, user station, mobile station, mobile device, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device, etc. The terminal device may be a station (STAION, 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 capabilities, a computing device, or other processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, and a next-generation communication system. For example, a terminal device in an NR network or a terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0039] By way of example and not limitation, in embodiments of the present application, the terminal device may also be a wearable device. A wearable device may also be referred to as a wearable intelligent device, which is a general term for devices developed by applying wearable technologies to intelligentize daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is either 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. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can achieve complete or partial functions without relying on a smartphone, such as smart watches or smart glasses, etc., and those that only focus on a certain type of application function and need to cooperate with other devices such as smartphones, such as various smart bracelets and smart jewelry for physical sign monitoring.

[0040] A network device may be a device used to communicate with a mobile device. The network device may be an access point (AP) in a WLAN, a Base Transceiver Station (BTS) in GSM or CDMA, a NodeB (NB) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, a network device or base station (gNB) in an NR network, or a network device in a future evolved PLMN network, etc.

[0041] In an embodiment of the present application, a network device provides services for a cell, and a terminal device communicates with the network device through transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell may be a cell corresponding to a network device (e.g., a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. Here, the small cell may include: a metro cell, a micro cell, a picocell, a femto cell, etc. These small cells have the characteristics of small coverage range and low transmission power, and are suitable for providing high-rate data transmission services.

[0042] Before introducing the technical solution of the present application, the related technologies of the present application are introduced as follows:

[0043] NR Rel-15 stipulates that when multiple overlapping Physical Uplink Control Channels (PUCCHs), or multiple PUCCHs and Physical Uplink Shared Channels (PUSCHs) need to satisfy a multiplexing timing relationship, they can be multiplexed for transmission on one channel. The definition of this multiplexing timing relationship can be found in TS38.213. Otherwise, the terminal device will determine this situation as an abnormal situation. The multiplexing timing relationship here is mainly to ensure that the terminal device has enough time to determine whether the information carried by different uplink channels needs to be multiplexed, and the time required for uplink control signaling (Uplink Control Information, UCI) concatenation, coding, etc. during multiplexed transmission.

[0044] When the multiplexing timing is satisfied, the terminal device first determines the overlapping PUCCH channel set Q as follows:

[0045] 1. Determine PUCCH A: The earliest-starting PUCCH among the overlapping channels. If there are multiple PUCCHs with the same start time, select the one with the longest duration. If both are the same, choose either one.

[0046] 2. Include the PUCCHs that overlap with PUCCH A in set Q.

[0047] 3. Include the PUCCHs that overlap with any PUCCH in set Q in set Q.

[0048] 4. Multiplex all the UCIs in set Q into one PUCCH, and determine PUCCH B according to the number of bits of UCI and PRI.

[0049] The terminal device determines whether PUCCH B overlaps with other PUCCHs. If so, steps 1 to 4 are repeated. The set Q determined by the above method is as Figure 2 shown.

[0050] After determining the overlapping PUCCH channel set Q, the terminal device determines a PUCCH according to the set Q to multiplex and transmit the UCI carried in the channels in the set Q. For the specific process, refer to TS38.213. If the PUCCH does not overlap with any PUSCH, the terminal device multiplexes the UCI for transmission within the PUCCH. If the PUCCH overlaps with at least one PUSCH, the terminal determines a PUSCH from the at least one PUSCH and multiplexes the UCI for transmission within the PUSCH. Specifically:

[0051] 1. The acknowledgement (ACK) / non-acknowledgement (NACK) information, and / or, channel state information (CSI) information carried in the channels in the set Q are multiplexed for transmission within the PUSCH;

[0052] 2. The scheduling request (SR) information carried in the channels in the set Q is not transmitted.

[0053] The process by which the terminal device determines a PUSCH from the at least one PUSCH includes:

[0054] (1) If the at least one PUSCH includes a first PUSCH scheduled by downlink control information (DCI) and a second PUSCH configured by high-layer signaling (ConfiguredGrantConfig or semiPersistentOnPUSCH), the determined PUSCH is one of the first PUSCHs. For example, if there are multiple first PUSCHs that meet the multiplexing conditions, the terminal device selects the first PUSCH with the earliest time within the carrier corresponding to the smallest serving cell identity (ID) (ServCellIndex) among the carriers of the multiple first PUSCHs as the determined PUSCH.

[0055] (2) If there are multiple PUSCHs (i.e., multiple first PUSCHs scheduled by DCI or multiple second PUSCHs configured by high-layer signaling) that meet the multiplexing conditions, the terminal selects the PUSCH with the earliest time within the carrier corresponding to the smallest serving cell ID (ServCellIndex) among the carriers of the multiple PUSCHs as the determined PUSCH.

[0056] In NR Rel-16, in order to better support Ultra Reliable Low Latency (URLLC) services, the physical channel can be configured with two levels of priority, namely high priority or low priority. Usually, URLLC services will use high-priority channels for transmission. If there are multiple overlapping uplink channels with different priorities, for channels with the same priority, the terminal device uses the working mechanism of Rel-15 to determine a multiplexed channel (if there is only one channel with this priority, the so-called multiplexed channel is the channel itself), that is, the terminal device obtains two multiplexed channels corresponding to different priorities respectively. If the multiplexed channels with different priorities overlap, the terminal device only transmits the high-priority multiplexed channel and discards the low-priority channel. Among them, HP represents high priority and LP represents low priority.

[0057] Specifically, Figure 3 For the schematic diagram of multiplexed channels with different priorities, as Figure 3 shown in the upper part, the high-priority channels include: PUCCH carrying URLLC SR, PUCCH carrying URLLC ACK / NACK, and PUSCH carrying URLLC service data. The low-priority channels include: PUCCH carrying eMBB ACK / NACK and PUCCH carrying CSI. In step 1, for the high-priority channels, the PUCCH carrying URLLC ACK / NACK and the PUSCH carrying URLLC service data overlap. Therefore, the terminal device uses the working mechanism of Rel-15 to determine that this PUSCH is the multiplexed channel, that is, this PUSCH can transmit URLLC service data and ACK / NACK, and this multiplexed channel can be described as a high-priority multiplexed channel. For the low-priority channels, the PUCCH carrying eMBB ACK / NACK and the PUCCH carrying CSI overlap. Therefore, the terminal device uses the working mechanism of Rel-15 to determine that this PUCCH carrying CSI is the multiplexed channel, that is, this PUCCCH can transmit eMBB ACK / NACK and CSI, and this multiplexed channel can be described as a low-priority multiplexed channel. Since the high-priority multiplexed channel and the low-priority multiplexed channel do not overlap, there is no situation where the terminal device only transmits the high-priority multiplexed channel and discards the low-priority channel.

[0058] Among them Figure 3 The difference between the lower part and the upper part is that: the high-priority multiplexed channel and the low-priority multiplexed channel shown in the lower part overlap. Therefore, in step 2, the terminal device only transmits the high-priority multiplexed channel and discards the low-priority channel.

[0059] In NR Rel-16, if the uplink channels with different priorities overlap, the terminal device discards the uplink channels with low priority and only transmits the uplink channels with high priority. The advantage of doing this is that the transmission delay requirements and reliability of the high-priority channels are guaranteed. However, considering that in practical applications, the low-priority channels are usually used to transmit large amounts of data for eMBB services, discarding the low-priority channels will cause a large number of data retransmissions, thereby reducing the system transmission efficiency. Therefore, in the design of NR Rel-17, it is considered to support multiplexing and transmitting different priority information to reduce the probability of discarding low-priority information and improve the system efficiency. However, when supporting multiplexing and transmitting different priority information, how to ensure the delay requirements and reliability requirements of different priority information is an urgent problem to be solved.

[0060] To solve the above technical problems, when the PUCCH overlaps with multiple PUSCHs with different priorities in the time domain in this application, the target PUSCH is determined according to the time-domain end positions of the multiple PUSCHs, and the UCI of the PUCCH is multiplexed into the target PUSCH for transmission, which is beneficial to ensuring the delay requirements and reliability requirements of different priority information.

[0061] The technical solution of this application will be elaborated in detail below:

[0062] Figure 4 It is an interaction flowchart of a wireless communication method 200 provided by an embodiment of this application. The method includes at least the following steps:

[0063] S210, if there is an overlap in the time domain between the physical uplink control channel PUCCH and N physical uplink shared channels PUSCH, the terminal device determines the target PUSCH from the N PUSCH according to the time-domain end positions of the N PUSCH, where the priority of the PUCCH is different from the priorities of the N PUSCH, and the priorities of the N PUSCH are the same, and N is a positive integer;

[0064] S220, the terminal device transmits the target PUSCH, where the target PUSCH includes the uplink control information UCI in the PUCCH. That is, the terminal device can multiplex the UCI in the PUCCH into the PUSCH for transmission.

[0065] Correspondingly, the network device receives the target PUSCH sent by the terminal device.

[0066] Optionally, the priority of the PUCCH is different from the priorities of the N PUSCH, including:

[0067] The priority of the PUCCH is higher than the priorities of the N PUSCH; or

[0068] The priority of the PUCCH is lower than that of the N PUSCHs.

[0069] That is, in this application, PUCCH and PUSCH with different priorities can be multiplexed onto one channel for transmission, rather than discarding the low-priority channel, which is beneficial to ensuring the reliability requirements of the low-priority channel.

[0070] In some embodiments, the N PUSCHs are all PUSCHs that overlap with the PUCCH in the time domain; or,

[0071] In some other embodiments, the N PUSCHs are PUSCHs that overlap with the PUCCH in the time domain and meet specific conditions.

[0072] Optionally, in some embodiments, the specific conditions may include at least one of the following:

[0073] A first condition determined according to the time-domain start position of the PUSCH;

[0074] A second condition determined according to the time-domain end position of the PUSCH;

[0075] A third condition determined according to the symbols for carrying UCI in the PUSCH;

[0076] The PUSCH scheduled by Downlink Contol Information (DCI).

[0077] By way of example and not limitation, the specific conditions include at least one of the following:

[0078] Meeting the data processing or preparation time delay determined according to the time-domain start position of the PUSCH;

[0079] Meeting the transmission time delay determined according to the time-domain end position of the PUSCH;

[0080] Meeting the transmission time delay determined according to the time-domain position for carrying UCI in the PUSCH;

[0081] According to whether the PUSCH is scheduled by the downlink control information DCI.

[0082] Selecting the target PUSCH from the PUSCHs filtered according to the specific conditions is beneficial to meeting the time delay requirements of the high-priority channel.

[0083] In the embodiments of the present application, the terminal device may select the target PUSCH only according to the time-domain end position of the N PUSCHs. In some other embodiments, the terminal device may select the target PUSCH in combination with other information. For example, the other information may be the time-domain end position of the PUSCH, the serving cell ID (ServCellIndex) corresponding to the PUSCH, etc. The present application is not limited thereto.

[0084] Optionally, in the embodiments of the present application, the time-domain start position may be a start symbol, the time-domain end position may be an end symbol, or may also be other time units, such as time slots, mini-slots, etc. The present application is not limited thereto.

[0085] As an example, the target PUSCH is the PUSCH with the earliest time-domain end position among the N PUSCHs.

[0086] In some cases, if there is only one PUSCH with the earliest time-domain end position among the N PUSCHs, the terminal device may determine the PUSCH with the earliest time-domain end position as the target PUSCH. ]>

[0087] In some other embodiments, the terminal device determines the target PUSCH according to the time-domain end position of the N PUSCHs, in combination with the time-domain start position of at least two PUSCHs among the N PUSCHs and / or the serving cell identifiers ID of at least two PUSCHs among the N PUSCHs.

[0088] For example, if there are multiple PUSCHs with the earliest time-domain end position among the N PUSCHs, in this case, the terminal device may further combine the time-domain start position of the multiple PUSCHs with the earliest time-domain end position and / or the serving cell ID corresponding to the multiple PUSCHs to determine the target PUSCH.

[0089] As an example, the target PUSCH is the PUSCH with the earliest time-domain start position among the P PUSCHs, and the P PUSCHs are the PUSCHs with the earliest time-domain end position among the N PUSCHs, where P is a positive integer.

[0090] As another example, the target PUSCH is the PUSCH with the largest or smallest serving cell identifier ID among the Q PUSCHs, and the Q PUSCHs are the PUSCHs with the earliest time-domain start position among the PUSCHs with the earliest time-domain end position among the N PUSCHs, where Q is a positive integer.

[0091] As another example, the target PUSCH is the PUSCH with the largest or smallest corresponding serving cell identification ID among T PUSCHs, and the T PUSCHs are the PUSCHs with the earliest time-domain end position among the N PUSCHs, where T is a positive integer.

[0092] When UCI is multiplexed and transmitted in PUSCH, it is usually mapped to the first K time-domain symbols of PUSCH for transmission, and the value of K is related to the scheduling parameters of PUSCH. The earlier the time-domain start position of PUSCH is, mapping UCI therein means that the actual time-domain start position of transmitting UCI is earlier, and the processing delay of UCI may be lower. However, if the PUSCH itself lasts for a relatively long time actually, then UCI may also occupy more time-domain symbols (i.e., K is larger) for transmission, and its transmission delay is not necessarily the lowest. Therefore, in the embodiments of the present application, when selecting PUSCH, combining the end position of PUSCH is beneficial to meeting the delay requirements of high-priority channels.

[0093] It should be understood that in the embodiments of the present application, selecting the target PUSCH according to the time-domain end position of PUSCH may be the first judgment condition for selecting the target PUSCH among multiple PUSCHs, or may also be a further judgment condition based on other judgment conditions. The embodiments of the present application do not limit this.

[0094] In other words, selection can be made first according to the time-domain end position of PUSCH, or selection can also be made further according to the time-domain position of the PUSCH on the basis of selecting a part of PUSCHs according to other information.

[0095] For example, selection can be made first according to the time-domain start position of PUSCH to determine the N PUSCHs, and further selection can be made according to the time-domain end position of the N PUSCHs.

[0096] As another example, selection is made first according to the serving cell ID corresponding to PUSCH to determine the N PUSCHs, and further selection is made according to the time-domain end position of the N PUSCHs.

[0097] In the embodiments of the present application, it is assumed that all PUSCHs that overlap with the PUCCH in the time domain or PUSCHs that overlap with the PUCCH in the time domain and meet specific conditions constitute a first PUSCH set. In some embodiments, the N PUSCHs may include all PUSCHs in the first PUSCH set. In other embodiments, the N PUSCHs include some PUSCHs in the first PUSCH set. That is, the N PUSCHs are PUSCHs that meet certain conditions screened out from the first PUSCH set.

[0098] As an example, the N PUSCHs are the PUSCHs with the earliest time domain start position among all the PUSCHs that overlap with the PUCCH in the time domain.

[0099] As another example, the N PUSCHs are the PUSCHs with the earliest time domain start position among the PUSCHs that overlap with the PUCCH in the time domain and satisfy specific conditions.

[0100] That is, the N PUSCHs can be the PUSCHs with the earliest time domain start position in the first PUSCH set.

[0101] In this case, it can be understood that the selection is first made according to the time domain start position of the PUSCH, and for the selected PUSCHs, the selection is further made in combination with the time domain end position of the PUSCH.

[0102] As an example, the PUSCH with the earliest time domain end position among the N PUSCHs can be selected as the target PUSCH.

[0103] If there are multiple PUSCHs with the earliest time domain end position, the terminal device can arbitrarily select one of them as the target PUSCH, or it can also make a selection in combination with other information, such as combining the serving cell identification ID corresponding to multiple PUSCHs with the earliest time domain end position to determine the target PUSCH.

[0104] As an example, the target PUSCH is the PUSCH with the largest or smallest serving cell identification ID among S PUSCHs, where the S PUSCHs are the PUSCHs with the earliest time domain end position among the N PUSCHs, and S is a positive integer.

[0105] Hereinafter, in combination with Figure 5 and Figure 6 the specific examples shown, the method for determining the target PUSCH is described.

[0106] As Figure 5 shown, one PUCCH overlaps with 5 PUSCHs. Among them, PUSCH 1 is transmitted in carrier (CC) 1 (i.e., ServCellIndex = 1), PUSCH 2 and PUSCH 3 are transmitted on different time domain symbols in CC 2 (i.e., ServCellIndex = 2), PUSCH 4 is transmitted in CC 3 (i.e., ServCellIndex = 3), and PUSCH 5 is transmitted in CC 4 (i.e., ServCellIndex = 4).

[0107] First, the PUSCH with the earliest starting symbol among the 5 PUSCHs can be determined. Among them, the starting symbols of PUSCH 1, PUSCH 2, and PUSCH 4 are the same and the earliest.

[0108] Second, the PUSCH with the earliest ending symbol among the PUSCHs with the earliest starting symbol is determined. Among them, the ending symbols of PUSCH 2 and PUSCH 4 are the same and the earliest.

[0109] Then, the target PUSCH is determined according to the ServCellIndex corresponding to the PUSCH. For example, the PUSCH in the CC with the smallest ServCellIndex can be selected. Among them, the CC corresponding to PUSCH 2 is the smallest, and PUSCH 2 can be determined as the target PUSCH.

[0110] Therefore, the UCI in the PUCCH can be multiplexed into PUSCH 2 for transmission.

[0111] As Figure 6 shown, one PUCCH overlaps with 4 PUSCHs. Among them, PUSCH 1 is transmitted in carrier (CC) 1 (i.e., ServCellIndex = 1), PUSCH 2 is transmitted on different time domain symbols in CC 2 (i.e., ServCellIndex = 2), PUSCH 3 is transmitted in CC 3 (i.e., ServCellIndex = 3), and PUSCH 4 is transmitted in CC4 (i.e., ServCellIndex = 4).

[0112] First, the PUSCH with the earliest ending symbol among the 4 PUSCHs can be determined. Among them, the ending symbols of PUSCH 2 and PUSCH 3 are the same and the earliest.

[0113] Second, the PUSCH with the earliest starting symbol among the PUSCHs with the earliest ending symbol is determined. Among them, the starting symbol of PUSCH 3 is the earliest, and PUSCH 3 can be determined as the target PUSCH.

[0114] Therefore, the UCI in the PUCCH can be multiplexed into PUSCH 3 for transmission.

[0115] Continue to participate Figure 6 , in another implementation, the PUSCH with the earliest ending symbol among the 4 PUSCHs can be determined first. Among them, the ending symbols of PUSCH 2 and PUSCH 3 are the same and the earliest.

[0116] Further determine the target PUSCH in combination with the ServCellIndex corresponding to the PUSCH with the earliest ending symbol. For example, the PUSCH within the CC with the smallest ServCellIndex can be selected. Among them, the CC corresponding to PUSCH 2 is the smallest, and PUSCH2 can be determined as the target PUSCH.

[0117] Therefore, the UCI in the PUCCH can be multiplexed into PUSCH 2 for transmission.

[0118] In summary, in the embodiments of the present application, if the PUCCH overlaps with multiple PUSCHs of different priorities, the terminal device can select a target PUSCH from the multiple PUSCHs according to the time-domain ending positions of the multiple PUSCHs, and further multiplex the UCI in the PUCCH into the target PUSCH for transmission, which is beneficial to ensuring the latency requirements and reliability requirements of the UCI in the PUCCH.
