Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a transmission method, a terminal and a network side device. Background Art

[0002] In the New Radio (NR) system, the coverage performance of Message 3 (Msg3) is poor compared to the coverage performance of other channels, which makes it difficult for terminals in areas with poor signal coverage to access the cell. Therefore, NR Rel-17 introduces a mechanism for repeated transmission of Msg3 to improve the coverage performance of Msg3. The NR system supports single transmission of Msg3. The transmission time slot of Msg3 can be determined according to the scheduling information of Message 2 (Msg2) or the physical downlink control channel (PDCCH) scrambled by the temporary cell radio network temporary identifier (TC-RNTI). However, when Msg3 is transmitted repeatedly, Msg3 needs to occupy multiple time slots. The terminal and network side equipment need to determine which time slots in the subsequent time slots can be used for Msg3 repeated transmission, especially whether flexible time slots or time slots containing flexible symbols can be used for Msg3 repeated transmission. If flexible time slots or symbols can be used for Msg3 repeated transmission, the efficiency of Msg3 repeated transmission will be greatly improved. In an extreme case, all time slots are configured as flexible time slots, and how to determine the available uplink transmission resources for Msg3 is a problem that needs to be solved.

[0003] The NR system defines a method for the terminal to determine the uplink and downlink time slot configuration, and implements cell-specific and terminal-specific time slot configuration through radio resource control (RRC) signaling and downlink control information (DCI), providing the terminal with flexible uplink and downlink time slot configuration. However, the terminal-specific time slot configuration requires that all cell-specific and terminal-specific uplink and downlink time slot configuration information be configured to the terminal in the connected state. In the initial access phase, the terminal can only obtain the cell-specific uplink and downlink time slot configuration. In the connected state, the flexible symbols of the cell-specific configuration can be configured as downlink / uplink symbols, or downlink / uplink transmissions can be scheduled through the terminal-specific configuration. The terminal that initially accesses cannot obtain the terminal-specific uplink and downlink time slot configuration, which may cause repeated transmission of Msg3 and downlink transmission conflicts of the connected terminal (connected UE) in the flexible time slot or symbol. Similarly, if the terminal supports repeated transmission (PUCCH repetition for HARQ-Ack for Msg4 / B) of the physical uplink control channel (PUCCH) carrying the hybrid automatic repeat request confirmation (HARQ-ACK) of message 4 (Message 4, Msg4) or message B (Message B, MsgB), similar problems will be encountered.

[0004] In the related art, when a terminal performs uplink repeated transmission, since a connected terminal can receive more indication information than an idle or inactive terminal, the connected terminal and the idle or inactive terminal may have inconsistent understandings of the resources that can be used for uplink repeated transmission, resulting in a conflict between the uplink transmission and the downlink transmission of the connected terminal in the flexible time slot or symbol, and the success of the uplink repeated transmission cannot be ensured. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application.

[0032] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in 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 often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the following descriptions, but these technologies can also be applied to applications other than NR system applications, such as the 6th generation (6 thGeneration, 6G) communication system.

[0033] Figure 1 The following is a schematic diagram of the structure of a wireless communication system applicable to the embodiment of the present application. The wireless communication system includes a terminal 11 and a network side device 12. The terminal 11 may also be referred to as a terminal device or a user terminal (User Equipment, UE). The terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices, and the wearable device includes: a smart watch, a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 can be a base station or a core network, wherein the base station can be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base TransceiverStation, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving Point, TRP) or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0034] NR supports two types of random access procedures: 4-step Random access channel (4-step RACH) type of message 1 (Message 1, Msg1) and 2-step Random access channel (2-step RACH) type of message A (Message A, MsgA). Both types of random access (RA) procedures support contention based random access (CBRA) and contention free random access (CFRA). The 2-step RACH process is generally used in areas with good coverage to shorten the terminal access time. For areas with poor signal coverage, the terminal should use the 4-step RACH process to access the cell.

[0035] In 4-step RACH, the UE first sends Msg1, including the preamble, to the network side device. After sending the preamble, the UE will monitor the PDCCH within the random access response (RAR) time window and use the fallback DCI format, i.e., DCI 1_0, to receive the RAR scheduled by the PDCCH scrambled with the random access radio network temporary identifier (RA-RNTI). If the preamble index index in the RAR is the same as the preamble index sent by the UE, it is considered that the RAR has been successfully received. At this time, the UE can stop monitoring the RAR and send Msg3 according to the authorization indication carried in the RAR; Msg3 is transmitted on the uplink shared channel (UL-SCH) and uses the hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ), scrambles the PDCCH with the TC-RNTI indicated by the RAR, and uses the fallback DCI format, i.e. DCI0_0, to schedule the retransmission of Msg3. Msg3 needs to contain the unique identity of each UE. This flag will be used for contention resolution in step 4. After receiving Msg3, the network side device will schedule Msg4 with DCI0_0 encrypted with TC-RNTI. When the UE successfully decodes the terminal conflict resolution identity media access control control unit (UEContention Resolution Identity MAC control element) contained in Msg4 and matches it with the UE ContentionResolution Identity sent by Msg3, the UE will consider the random access to be successful and set the TC-RNTI carried in the RAR to the cell radio network temporary identity (Cell Radio Network Temporary Identity, C-RNTI), thus completing the 4-step random access.

[0036] The NR system has flexible uplink and downlink time slot configuration. There are three types of OFDM symbols for wireless resources: downlink symbol DL symbol, uplink symbol UL symbol and flexible symbol. Flexible symbols can be used to transmit downlink signals as well as uplink signals. The actual transmission situation is determined by the actual scheduling situation of the system. The uplink and downlink time slot configuration of NR adopts a semi-static configuration method, and flexible time slot configuration is achieved through RRC signaling (tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-Configuration Dedicated) and downlink control information (DCI 2_0).

[0037] When Msg3 is repeatedly transmitted, Msg3 needs to occupy multiple time slots. The terminal can determine the first transmission time slot of Msg3 according to the timing relationship; in addition, the terminal and the base station need to determine which time slots in the subsequent multiple time slots can be used for repeated transmission of Msg3. In particular, determine whether the flexible time slot or the time slot containing the flexible symbol can be used for repeated transmission of Msg3.

[0038] In the connected state, the flexible symbol configured exclusively in the cell can be configured as a downlink symbol through the terminal-specific configuration, or the downlink transmission can be scheduled or configured, which will cause the transmission of Msg3 to conflict with the downlink transmission. That is, for the connected terminal, since more indication information can be received, the understanding of the resources that can be used for repeated transmission may be different from that of the idle / inactive UE.

[0039] Similarly, if the terminal supports PUCCH repetition for HARQ-Ack for MSG4 / B, a similar problem will be encountered, that is, it is necessary to determine whether the flexible time slot or the time slot containing the flexible symbol can be used for these PUCCH repetition for HARQ-Ack for Msg4 / B.

[0040] In addition, since idle / inactive UEs need to monitor the PDCCH of Type 1 / 2 common search space (CSS), they may also be configured on flexible symbols of the cell-specific uplink configuration (tdd-UL-DL-ConfigCommon), which may also cause conflicts with resources that can be used for uplink repeated transmissions.

[0041] Since the UE will also trigger the contention random access process in the connected state, and the network cannot distinguish whether the PRACH transmission comes from an idle / inactive UE or a connected UE, it is necessary to ensure that the transmission resources of various repeated transmissions of the idle / inactive UE and the connected UE in determining the random access process are the same.

[0042] Furthermore, when Msg3 PUSCH retransmission or PUCCH repetition for HARQ-Ackfor MSG4 / B is supported, the possibility of uplink retransmission in the random access process overlapping with some downlink transmissions (for example, some PDCCHs) becomes greater. Therefore, it is necessary to design a mechanism to determine the available uplink transmission resources to avoid conflicts with downlink transmissions and ensure that connected terminals and idle or inactive terminals have a consistent understanding of the resources that can be used for uplink retransmission.

[0043] The transmission method, terminal and network side device provided in the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0044] Figure 2 One of the flow charts of the transmission method provided in the embodiment of the present application is as follows: Figure 2 As shown, the method comprises the following steps:

[0045] Step 200: When there are overlapping resources between a first uplink transmission resource and a first downlink transmission resource of a terminal, the terminal performs a first uplink transmission on the first uplink transmission resource, or the terminal performs a first downlink reception on the first downlink transmission resource.

[0046] Optionally, the terminal first determines whether there are overlapping resources between the first uplink transmission resource and the first downlink transmission resource.

[0047] It can be understood that the overlap between the first uplink transmission resource and the first downlink transmission resource of the terminal indicates that there is a conflict between the uplink transmission and the downlink transmission of the terminal.

[0048] For example, a connected terminal can configure a flexible symbol configured exclusively in a cell as a downlink symbol through terminal-specific configuration, or schedule or configure downlink transmission, which will cause a conflict between the uplink transmission and the downlink transmission at the flexible symbol, and the flexible symbol is an overlapping resource.

[0049] Among them, the first uplink transmission resource refers to a resource that can be used for the first uplink transmission, for example, it can be a resource that can be used for Msg3 PUSCH transmission, a resource that can be used for HARQ-Ack for MSG4 / B PUCCH transmission, a resource that can be used for Msg3 repetition transmission, and a resource that can be used for PUCCH repetition for HARQ-Ack for MSG4 / B.

[0050] In the case where the first uplink transmission resource and the first downlink transmission resource of the terminal have overlapping resources, in one implementation mode, the terminal performs the first uplink transmission on the first uplink transmission resource.

[0051] It can be understood that, when the first uplink transmission resource and the first downlink transmission resource of the terminal overlap, the terminal performs the first uplink transmission on the first uplink transmission resource, and the terminal does not perform the first downlink reception on the first downlink transmission resource.

[0052] In one implementation, the terminal performs a first downlink reception on the first downlink transmission resource.

[0053] It can be understood that, when the first uplink transmission resource and the first downlink transmission resource of the terminal overlap, the terminal performs the first downlink reception on the first downlink transmission resource, and does not perform the first uplink transmission on the first uplink transmission resource.

[0054] In an embodiment of the present application, when there are overlapping resources between the first uplink transmission resource and the first downlink transmission resource of the terminal, the terminal performs uplink transmission or downlink reception. Since the embodiment of the present application clarifies the behavior of the terminal when there are overlapping uplink transmission resources and downlink transmission resources, the connected terminal and the idle or inactive terminal can have a consistent understanding of the resources that can be used for uplink repeated transmission, thereby avoiding conflicts between uplink transmission and downlink transmission.

[0055] Optionally, the first uplink transmission includes at least one of the following:

[0056] Message 3 Msg3: Transmission of physical uplink shared channel PUSCH;

[0057] Transmission of message A MsgA physical uplink shared channel PUSCH;

[0058] Transmission of the physical uplink control channel PUCCH carrying the hybrid automatic repeat request confirmation HARQ-ACK of message 4 Msg4 or message B MsgB.

[0059] Optionally, the transmission of the Msg3 PUSCH includes at least one of the following:

[0060] Initial transmission scheduled by random access response uplink grant RAR UL grant;

[0061] The retransmission scheduled by the physical downlink control channel PDCCH is scrambled by the temporary cell radio network temporary identifier TC-RNTI.

[0062] Among them, Msg4 is used to transmit contention resolution information for contention random access, and the Msg4 is scheduled by downlink DCI scrambled by TC-RNTI.

[0063] Among them, MsgA is a physical random access channel (PRACH) and a physical uplink shared channel (PUSCH) sent in a two-step random access.

[0064] MsgB is a random access response (RACH Access Response, RAR) of a 2-step random access.

[0065] Optionally, the first downlink transmission resource includes at least one of the following:

[0066] PDCCH monitoring timing;

[0067] Resources for receiving paging early indication (PEI);

[0068] A resource for receiving a downlink reference signal;

[0069] The time unit of the PDCCH for scheduling broadcast or multicast services;

[0070] The time unit of the Physical Downlink Shared Channel (PDSCH) for scheduling broadcast or multicast services;

[0071] Semi-persistent scheduling (SPS) is the time unit for PDSCH reception;

[0072] The terminal-specific signaling or dynamic signaling indicates a time unit for downlink;

[0073] The time unit for transmission of synchronization signal block SSB.

[0074] Optionally, the monitoring opportunity of the PDCCH includes:

[0075] The monitoring time of the physical downlink control channel PDCCH of scheduling message 2 Msg2, MsgB, Msg4 or Msg3;

[0076] Monitoring timing of paging PDCCH;

[0077] Schedule the monitoring timing of the PDCCH of the System Information Block (SIB).

[0078] Among them, Msg2 is a random access response (RACH Access Response, RAR) of a 4-step random access.

[0079] Flexible symbols configured by the network can be used for uplink transmission or downlink reception. When the configured or scheduled uplink transmission and downlink reception overlap, especially when the flexible symbols overlap, it is necessary to determine reasonable terminal behavior to avoid transmission conflicts between downlink reception and uplink transmission.

[0080] The network may configure and schedule the first downlink transmission resource on the flexible symbol, including at least one of the following:

[0081] a) The monitoring occasion (i.e. type 2 CSS) of the PDCCH that schedules Msg2, MsgB, Msg4 or Msg3;

[0082] b) Monitoring occasion of Paging PDCCH (type 1CSS);

[0083] c) Receive resources from PEI;

[0084] d) PDCCH or PDSCH scheduling broadcast or multicast services;

[0085] e) SPS PDSCH reception;

[0086] f) Dedicated signaling or dynamic signaling indicates a downlink symbol or time slot;

[0087] If the monitoring occasions of these PDCCHs overlap with the symbols or time slots of the first uplink transmission occasions, it is necessary to clarify the sending or receiving behavior of the terminal. One solution is not to perform the first uplink transmission on these first downlink transmission resources.

[0088] For example, for the monitoring occasion of PDCCH of Msg2, Msg-B, Msg4 or Msg3, that is, the monitoring occasion of type-1CSS, these downlink receptions are also downlink receptions in the random access process. In this case, no uplink transmission is performed, but these downlink receptions are performed, so that the Msg3 or Msg4 scheduling can be received as early as possible, so that the random access process can be completed as early as possible, thereby speeding up the random access process.

[0089] For example, the symbols or time slots for receiving the paging PDCCH and PEI may not be used for the first uplink transmission. The Paging PDCCH is used to transmit system information updates or paging messages, and the PEI is used to indicate whether the terminal monitors the paging PDCCH. This has the advantage of ensuring the reliability of the paging PDCCH transmission and reducing the paging delay.

[0090] For example, symbols or time slots for receiving broadcast or multicast services may not be used for the first uplink transmission. This has the advantage of ensuring the reliability of broadcast or multicast service transmission and reducing transmission delay.

[0091] In the above examples, downlink transmission is prioritized over uplink transmission. On the contrary, the first uplink transmission may be prioritized over the first downlink reception, which is beneficial for completing the first uplink transmission as early as possible and improving the performance of the first uplink transmission.

[0092] Optionally, the overlapping resources include flexible time units. Optionally, the time unit may be a time slot, a symbol, a sub-time slot, etc.

[0093] Optionally, the performing of the first uplink transmission or the first downlink reception is determined according to at least one of the following:

[0094] Network configuration;

[0095] Content of PUSCH or PUCCH transmission;

[0096] Terminal capabilities or types.

[0097] In one implementation, the terminal determines to perform a first uplink transmission or a first downlink reception according to a network configuration.

[0098] Optionally, the terminal determines whether the overlapping resources can be used for the first uplink transmission, and performs the first uplink transmission if it is determined that the overlapping resources can be used for the first uplink transmission; if it is determined that the overlapping resources cannot be used for the first uplink transmission, the terminal performs the first downlink reception.

[0099] In one implementation, the terminal determines to perform the first uplink transmission or the first downlink reception according to the content of the PUSCH or PUCCH transmission.

[0100] For example, if Msg3 contains a common control channel (CCCH) service data unit (SDU), C-RNTI MAC-CE, or a scheduling request (SR) / buffer status report (BSR), the terminal determines to perform the first uplink transmission.

[0101] In one implementation, the terminal determines to perform the first uplink transmission or the first downlink reception according to the terminal capability or type.

[0102] For example, if the terminal is a half-duplex terminal of a frequency division duplex (FDD) frequency band, the first uplink transmission is performed.

[0103] Optionally, the first uplink transmission includes at least one transmission among multiple repeated transmissions.

[0104] Optionally, the performing the first uplink transmission includes:

[0105] When the terminal performs K uplink repeated transmissions and the transmission resource of the kth uplink transmission overlaps with the first downlink transmission resource so that the kth uplink transmission does not actually occur, the terminal performs one of the following:

[0106] Recording the kth uplink transmission that did not actually occur as a repeated transmission;

[0107] The kth uplink transmission that did not actually occur is not recorded as a repeated transmission;

[0108] Among them, 1≤k≤K.

[0109] It can be understood that if the terminal performs K uplink repeated transmissions, and the transmission resources of the kth uplink transmission overlap with the first downlink transmission resources, resulting in the kth uplink transmission not actually occurring, the terminal may choose to ignore the kth uplink transmission and record the kth uplink transmission that did not actually occur as a repeated transmission.

[0110] Alternatively, the terminal may also choose to postpone the kth uplink transmission, and not record the kth uplink transmission that has not actually occurred as a repeated transmission. The terminal continues to determine available uplink transmission resources until K uplink transmissions are actually performed.

[0111] Optionally, the first uplink transmission resource satisfies:

[0112] The transmission resources of the first PUSCH or PUCCH do not overlap with the first downlink transmission resources, wherein the transmission of the first PUSCH or PUCCH is the first transmission among multiple repeated transmissions scheduled or configured.

[0113] That is, it is agreed that for the first PUXCH scheduled or configured for PUXCH with K>1, the transmission resources of the first PUXCH do not overlap with the first downlink transmission resources, where the PUXCH is PUSCH or PUCCH.

[0114] It should be noted that for a terminal in a connected state, it is possible to obtain exclusive signaling sent by a network-side device to reconfigure flexible symbols into uplink symbols, downlink symbols, or flexible symbols, or to obtain dynamic instructions from a network-side device to modify flexible symbols into uplink symbols, downlink symbols, or flexible symbols. That is, a terminal in a connected state can obtain more information to determine how the network allocates uplink and downlink transmission resources. However, this will result in inconsistencies in the uplink transmission resources determined by terminals in a connected state and an idle state / inactive state. The network cannot distinguish whether the process of competing for random access is initiated by an idle / inactive state terminal or a connected state terminal. Therefore, it is necessary to determine a certain mechanism so that the uplink transmission resources determined in the connected state and the idle state / inactive state are consistent.

[0115] One processing method is to always use the mechanism for determining the first uplink transmission resource of the idle state terminal, that is, for the connected state terminal, the first uplink transmission resource is determined by using the same mechanism as that of the idle / inactive state terminal.

[0116] Optionally, the method further includes: the terminal determining the first uplink transmission resource based on at least one of the following:

[0117] Cell-specific uplink and downlink configuration;

[0118] SSB;

[0119] The monitoring timing of the PDCCH that schedules the SIB;

[0120] Schedule the monitoring opportunity of the PDCCH of Msg2, Msg3, Msg4 or MsgB;

[0121] Monitoring timing of paging PDCCH;

[0122] Downlink receiving resources for broadcast or multicast services;

[0123] Receive resources from PEI.

[0124] In the embodiment of the present application, the terminal may be a connected terminal or an idle / inactive terminal.

[0125] A connected terminal or an idle / inactive terminal determines resources that can be used for a first uplink transmission, i.e., first uplink transmission resources, based on the cell-specific uplink and downlink configurations, SSB, the monitoring occasion of the PDCCH that schedules the SIB, the monitoring occasion of the PDCCH that schedules the Msg2 / 3 / 4, the downlink reception resources of the broadcast or multicast service, the reception resources of the PEI, and at least one of the monitoring resources of the paging PDCCH.

[0126] Optionally, the terminal determines the first uplink transmission resource in Figure 2 It occurs before step 200 in step 200. It should be noted that the first uplink transmission resource and the first downlink transmission resource of the terminal in step 200 have overlapping resources, which is from the perspective of resource conflict. After the terminal determines the first uplink transmission resource using the method of the embodiment of the present application, if the resource conflict still exists, indicating that there is no available uplink transmission resource, the terminal does not perform the first uplink transmission on the first uplink transmission resource, and performs the first downlink reception on the first downlink transmission resource.

[0127] In an embodiment of the present application, a connected terminal uses the same mechanism as an idle or inactive terminal to determine the first uplink transmission resource, so that the connected terminal and the idle or inactive terminal have the same understanding of the resources that can be used for uplink repeated transmission, thereby avoiding conflicts between uplink transmission and downlink transmission.

[0128] Optionally, when the terminal determines the first uplink transmission resource, if the terminal is in a connected state, the terminal further performs at least one of the following:

[0129] Ignore the uplink and downlink configuration information of terminal-specific signaling;

[0130] Ignore the PDCCH indication information of the dynamic indication time slot structure;

[0131] The PDSCH of SPS is not received;

[0132] Do not monitor PDCCH;

[0133] The downlink reference signal is not received.

[0134] It can be understood that, for connected terminals, while adopting the same mechanism as idle / inactive terminals to determine the first uplink transmission resource, at least one of the following is performed: ignoring the terminal-specific configuration on the flexible time unit, ignoring the indication information of the PDCCH that dynamically indicates the time slot structure, not receiving the PDSCH of the SPS, not monitoring the PDCCH, and not receiving the downlink reference signal.

[0135] Among them, the monitoring of PDCCH is not limited to the PDCCH monitoring in the aforementioned embodiments (i.e., physical downlink control channel PDCCH monitoring of scheduling message 2Msg2, MsgB, Msg4 or Msg3; paging PDCCH monitoring; monitoring of PDCCH of scheduling system information block SIB), but can also be PDCCH monitoring configured exclusively for the terminal.

[0136] Among them, the downlink reference signal includes: a reference signal configured exclusively for a cell or a reference signal configured exclusively for a terminal, including a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a phase tracking reference signal (PTRS), a positioning reference signal (PRS), etc.

[0137] Optionally, for connected terminals, when determining available uplink transmission resources, ignore the terminal-specific configuration on the flexible time unit and / or ignore the indication information of the PDCCH that dynamically indicates the time slot structure. If, after ignoring this information, the first uplink transmission resource and the first downlink transmission resource do not overlap, then the first uplink transmission resource is determined to be a resource that can be used for the first uplink transmission, and the first uplink transmission is performed on the first uplink transmission resource.

[0138] Optionally, since idle / inactive state terminals will not receive PDSCH of SPS, monitor PDCCH, or receive downlink reference signals, in order to ensure that connected state terminals and idle state or inactive state terminals have a consistent understanding of resources that can be used for uplink repeated transmissions, connected state terminals also cannot receive PDSCH of SPS, monitor PDCCH, or receive downlink reference signals.

[0139] That is, once the network schedules the first uplink transmission and uses the same mechanism as that for idle / inactive terminals to determine the first uplink transmission resources, if these first uplink transmission resources also include flexible symbols indicated by the cell configuration, the network will ensure that these flexible symbols will be used for uplink transmission, and the network ensures that no downlink transmission will be performed on these flexible symbol resources.

[0140] For connected terminals, if dedicated signaling or DCI has been received to configure or indicate that these flexible symbols are downlink or flexible, the terminal ignores the dedicated signaling or dynamically indicated uplink and downlink symbol configuration information that has been sent. If high-level signaling (Radio Resource Control (RRC) or Media Access Control (MAC) Control Element (CE)) is received to configure PDCCH monitoring on these flexible symbols, or to receive SPS, the terminal will no longer monitor these PDCCHs and will not receive the PDSCH of the configured SPS.

[0141] In an embodiment of the present application, when there are overlapping resources between the first uplink transmission resource and the first downlink transmission resource of the terminal, the connected terminal ignores the terminal-specific configuration on the flexible time unit and / or ignores the indication information of the PDCCH that dynamically indicates the time slot structure, does not receive the PDSCH of the SPS, monitors the PDCCH, and receives the downlink reference signal. This allows the connected terminal and the idle or inactive terminal to have a consistent understanding of the resources that can be used for uplink repeated transmission, so that the first uplink transmission resource determined by the connected terminal no longer overlaps with the first downlink transmission resource, and the first uplink transmission can be performed directly on the first uplink transmission resource, thereby avoiding conflicts between uplink and downlink transmissions.

[0142] Figure 3 The second flow chart of the transmission method provided in the embodiment of the present application. Figure 3 Said method comprises the following steps:

[0143] Step 300: The network side device performs a first uplink reception according to a first uplink transmission resource determined by the terminal, or the network side device performs a first downlink transmission according to a first downlink transmission resource of the terminal.

[0144] Since there are overlapping resources between the first uplink transmission resource and the first downlink transmission resource of the terminal, the terminal performs a first uplink transmission on the first uplink transmission resource, or the terminal performs a first downlink reception on the first downlink transmission resource. Correspondingly, the network side device performs a first uplink reception according to the first uplink transmission resource determined by the terminal, or the network side device performs a first downlink transmission according to the first downlink transmission resource of the terminal.

[0145] Optionally, the first uplink receiving includes at least one of the following:

[0146] Reception of message 3Msg3 physical uplink shared channel PUSCH;

[0147] Reception of message A MsgA physical uplink shared channel PUSCH;

[0148] Reception of the physical uplink control channel PUCCH carrying the hybrid automatic repeat request confirmation HARQ-ACK message 4 Msg4 or message B MsgB.

[0149] Optionally, the receiving of the Msg3 PUSCH includes at least one of the following:

[0150] Initial transmission scheduled by random access response uplink grant;

[0152] Optionally, the first downlink transmission resource includes at least one of:

[0153] PDCCH monitoring timing;

[0154] A resource for receiving a paging early indication PEI;

[0155] A resource for receiving a downlink reference signal;

[0156] The time unit of the PDCCH for scheduling broadcast or multicast services;

[0157] A time unit for scheduling a physical downlink shared channel PDSCH for broadcast or multicast services;

[0166] Optionally, it also includes:

[0167] The network side sends configuration information to the terminal, where the configuration information is used to instruct the terminal to perform a first uplink transmission or a first downlink reception.

[0168] It can be understood that when there are overlapping resources between the first uplink transmission resource and the first downlink transmission resource of the terminal, whether the terminal performs the first uplink transmission on the first uplink transmission resource or the first downlink reception on the first downlink transmission resource can be determined based on the configuration information sent by the network side device.

[0169] Optionally, the first uplink reception includes at least one reception among multiple repeated receptions.

[0170] Optionally, the performing the first uplink reception includes:

[0171] The network side device performs the first uplink reception according to the terminal's repeated transmission method.

[0172] The terminal repeats transmission in the following ways:

[0173] When the terminal performs K uplink repeated transmissions and the transmission resource of the kth uplink transmission overlaps with the first downlink transmission resource so that the kth uplink transmission does not actually occur, the terminal performs one of the following:

[0174] Recording the kth uplink transmission that did not actually occur as a repeated transmission;

[0175] The kth uplink transmission that did not actually occur is not recorded as a repeated transmission;

[0176] Among them, 1≤k≤K.

[0177] It can be understood that if the terminal performs K uplink repeated transmissions, and the transmission resources of the kth uplink transmission overlap with the first downlink transmission resources, resulting in the kth uplink transmission not actually occurring, the terminal may choose to ignore the kth uplink transmission, and record the kth uplink transmission that did not actually occur as a repeated transmission, and the network side device will also ignore the kth uplink reception.

[0178] Alternatively, the terminal may also choose to delay the kth uplink transmission, and not record the kth uplink transmission that did not actually occur as a repeated transmission. The terminal continues to determine the available uplink transmission resources until K actual uplink transmissions are performed, and the network side device will also delay the kth uplink reception.

[0179] Optionally, the first uplink transmission resource satisfies:

[0180] The transmission resources of the first PUSCH or PUCCH do not overlap with the first downlink transmission resources, wherein the transmission of the first PUSCH or PUCCH is the first transmission among multiple repeated transmissions scheduled or configured.

[0181] In an embodiment of the present application, the network side device performs a first uplink reception according to the first uplink transmission resource determined by the terminal, or the network side device performs a first downlink transmission according to the first downlink transmission resource of the terminal. Since the network side device in the embodiment of the present application performs corresponding transmission according to the transmission resource of the terminal, conflicts between uplink transmission and downlink transmission can be effectively avoided, thereby improving transmission efficiency.
