Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone.

[0056] In this application embodiment, the "protocol" may refer to a standard protocol in the field of communication, such as the LTE protocol, the NR protocol, and related protocols applied to future communication systems. This application does not limit this.

[0057] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0058] The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communication (URLLC), and Massive Machine Type Communication (mMTC).

[0059] eMBB still aims to provide users with multimedia content, services, and data, and its demand is growing rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and needs vary considerably. Therefore, generalizations cannot be made; a detailed analysis based on the specific deployment scenario is necessary. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan.

[0060] NR is deployed at high frequencies. To improve coverage, 5G introduces a beam sweeping mechanism to meet coverage requirements (trading space for coverage, and time for space), such as... Figure 2 As shown.

[0061] After the introduction of beam sweeping, a synchronization signal needs to be sent in each beam direction. The 5G synchronization signal is given in the form of a synchronization signal block (SS / PBCH block, SSB), which includes the primary synchronization signal (PSS), secondary synchronization signal (SSS), and physical broadcast channel (PBCH).

[0062] 5G synchronization signals appear periodically in the time domain in the form of synchronization signal burst sets.

[0063] The actual number of beams transmitted in each cell is determined by the network-side configuration, but the frequency at which the cell is located determines the maximum number of beams that can be configured.

[0064] In 5G, the maximum channel bandwidth can be 400MHz (e.g., wideband carrier), which is significantly larger than the maximum 20MHz bandwidth of LTE. If a terminal device operates solely on a wideband carrier, its power consumption will be substantial. Therefore, the radio frequency (RF) bandwidth of the terminal device can be adjusted based on its actual throughput. A Band Width Part (BWP) is introduced to optimize power consumption. For example, if the terminal device has a low data rate, a smaller bandwidth can be configured for it (e.g., wideband carrier). Figure 3 As shown in (a) above, if the terminal device has high speed requirements, a larger bandwidth can be configured for the terminal device (e.g., ...). Figure 3 (as shown in (b)). If the terminal device supports high speed, or operates in Carrier Aggregation (CA) mode, multiple BWPs can be configured for the terminal device (e.g., ...). Figure 3 (as shown in (c)). Another purpose of BWP is to trigger the coexistence of multiple numerology sets in a cell.

[0065] In some embodiments, a terminal device can be configured with up to four uplink (UL) BWPs and up to four downlink (DL) BWPs via Radio Resource Control (RRC) dedicated signaling, but only one DL BWP and one UL BWP can be active at a time. The RRC dedicated signaling can indicate the first active BWP among the configured BWPs. Furthermore, while the terminal device is in a connected state, it can switch between different BWPs via Downlink Control Information (DCI). When a carrier that is in an inactive state enters an active state, the first active BWP is the first active BWP configured in the RRC.

[0066] In some embodiments, the configuration parameters for each BWP include:

[0067] Subcarrier spacing;

[0068] Cyclic prefix;

[0069] The first physical resource block (PRB) of the BWP and the number of consecutive PRBs;

[0070] Location and bandwidth;

[0071] BWP identifier (bwp-Id);

[0072] BWP common configuration parameters (bwp-Common) and dedicated configuration parameters (bwp-Dedicated).

[0073] In some embodiments, during radio link monitoring (RLM), the UE only performs the measurement on the active BWP; inactive BWPs do not require operation. Furthermore, when switching between different BWPs, RLM-related timers and counters do not need to be reset. For Radio Resource Management (RRM) measurements, the UE's ability to transmit and receive data on any active BWP does not affect the RRM measurement. Similarly, for Channel Quantity Indicator (CQI) measurements, the UE only needs to perform the measurement on the active BWP.

[0074] When a carrier is deactivated and then activated by the Media Access Control Element (MAC CE), the initial first activated BWP is the BWP corresponding to the first activated BWP identifier (BWP id) in the RRC signaling.

[0075] In RRC signaling, the BWP id takes values ​​from 0 to 4, with 0 being the default initial BWP.

[0076] In DCI, the BWP indicator is 2 bits. If the number of configured BWPs is 3 or less, then BWP indicator = 1, 2, 3 corresponds to BWP ID = 1, 2, 3 respectively. If the number of BWPs is 4, then BWP indicator = 0, 1, 2, 3 corresponds to the BWPs configured according to their sequential index. Furthermore, the network side uses consecutive BWP IDs when configuring BWPs.

[0077] Carrier aggregation (CA) is the process of jointly scheduling and utilizing resources on multiple component carriers (CCs) to enable NR systems to support greater bandwidth, thereby achieving higher peak system rates. Based on the continuity of the aggregated carriers in the spectrum, it can be divided into continuous carrier aggregation and discontinuous carrier aggregation; based on whether the aggregated carriers belong to the same band, it can be divided into intra-band carrier aggregation and inter-band carrier aggregation.

[0078] There is one and only one Primary Cell Component (PCC). The PCC provides RRC signaling connections, Non-Access Stratum (NAS) functions, security, etc. The Physical Uplink Control Channel (PUCCH) exists only on the PCC. The Secondary Cell Component (SCC) only provides additional radio resources. The PCC and SCC are collectively referred to as the serving cell. A maximum of five aggregated carriers are supported, meaning the maximum bandwidth after aggregation is 100MHz, and the aggregated carriers belong to the same base station. All aggregated carriers use the same Cell Radio Network Temporary Identity (C-RNTI), and the base station implementation ensures that the C-RNTI does not conflict in each carrier's cell. Because both asymmetric and symmetric carrier aggregation are supported, the aggregated carriers must have downlink capabilities, but uplink is not required. Furthermore, a primary carrier cell must have its own Physical Downlink Control Channel (PDCCH) and PUCCH. Only the primary carrier cell has a PUCCH, while other secondary carrier cells may have a PDCCH.

[0079] SCells are configured via dedicated RRC signaling. Initially, they are in an inactive state, unable to send or receive data. SCells are then activated via MAC CE to enable data transmission and reception. For example... Figure 4 As shown, a SCell is activated or deactivated using one 8-bit byte (octet) of the MAC CE. For example, as... Figure 5 As shown, SCells are activated or deactivated using four 8-bit bytes (octet, Oct) of the MAC CE. Specifically, setting a bit to 0 indicates deactivation of the corresponding SCell, and setting it to 1 indicates activation; or, setting a bit to 1 indicates deactivation of the corresponding SCell, and setting it to 0 indicates activation.

[0080] In some embodiments, the state of an Scell ​​can be configured in RRC signaling. When adding a configuration to an Scell, the Scell's state is configured to be active via RRC signaling; otherwise, it is deactivated by default.

[0081] To facilitate a better understanding of the embodiments of this application, the technical problems that this application needs to solve are described.

[0082] Currently, the MAC CE method requires a delay from the activation of an Scell ​​to its actual data transmission capability. Considering that the length of the large SSB period affects the actual activation time of the Scell, TRS is introduced to assist terminal devices in quickly activating the Scell. TRS transmission occupies two consecutive time slots, which may conflict with other transmissions. For example, TRS transmission may conflict with transmissions on the UL time slot, causing TRS transmission to fail. How to identify and handle conflicts is a problem that needs to be solved.

[0083] Based on the above problems, this application proposes a scheme for identifying and handling transmission conflicts, which can identify and handle conflicts between the transmission of the first reference signal and the uplink transmission. When the first reference signal is TRS, the terminal device can quickly activate SCell based on the first reference signal.

[0084] The technical solution of this application is described in detail below through specific embodiments.

[0085] Figure 6 This is a schematic interactive flowchart of a wireless communication method 200 according to an embodiment of this application, such as... Figure 6 As shown, the wireless communication method 200 may include at least some of the following:

[0086] S210, the network device sends first information and second information; wherein, the first information is used to determine transmission direction information, the second information is used to determine the time domain position information of the first reference signal, the first reference signal is used to activate the carrier, and the time domain position information of the first reference signal includes at least one reference signal cluster, and one reference signal cluster corresponds to two consecutive time slots;

[0087] S220, the terminal device receives first information, wherein the first information is used to determine transmission direction information;

[0088] S230, the terminal device receives second information, wherein the second information is used to determine the time-domain position information of the first reference signal, the first reference signal is used to activate the carrier, and the time-domain position information of the first reference signal includes at least one reference signal cluster, and one reference signal cluster corresponds to two consecutive time slots;

[0089] S240, the terminal device determines a first receiving scheme for receiving the first reference signal based on the first information and the second information.

[0090] In some embodiments, the first reference signal is a TRS or a reference signal with similar function to a TRS. Of course, the first reference signal can also be other reference signals, and this application is not limited to them.

[0091] It should be noted that the transmission of the first reference signal may conflict with the uplink transmission on the uplink time unit, and / or, the transmission of the first reference signal may conflict with the uplink transmission on the flexible time unit, thereby causing the transmission of the first reference signal to fail. For example, as Figure 7 As shown, the terminal device is configured to receive TRS on a first TRS cluster and a second TRS cluster. The first TRS cluster includes one DL timeslot and one UL timeslot, and the second TRS cluster includes two DL timeslots. Figure 7 As shown, in the first TRS cluster, there is a conflict between TRS transmission on the UL timeslot and uplink transmission on the uplink timeslot. Furthermore, the first TRS cluster contains Channel State Information Reference Signal (CSI-RS) resources 1, 2, 3, and 4, and the second TRS cluster also contains CSI-RS resources 1, 2, 3, and 4.

[0092] In this embodiment, the first information is used to determine transmission direction information, and the second information is used to determine the time-domain location information of the first reference signal. The first reference signal is used to activate the carrier, and the time-domain location information of the first reference signal includes at least one reference signal cluster, with one reference signal cluster corresponding to two consecutive time slots. Therefore, the terminal device can determine a first reception scheme for receiving the first reference signal based on the first information and the second information. This optimizes the reception method of the first reference signal and avoids conflicts between the transmission of the first reference signal and the transmission of other signals.

[0093] In some embodiments, the time unit described in this application includes, but is not limited to, one of the following: time slot, symbol.

[0094] It should be noted that both uplink and downlink transmissions are possible in flexible time slots and flexible symbols.

[0095] In some embodiments, the first information is carried via RRC signaling or DCI. For example, the first information may be at least one of the elements, fields, or domains in RRC signaling or DCI. Of course, the first information may also be carried via other signaling methods, and this application is not limited to this.

[0096] In some embodiments, the second information is carried via RRC signaling or DCI. For example, the second information may be at least one of the elements, fields, or domains in RRC signaling or DCI. Of course, the second information may also be carried via other signaling methods, and this application is not limited to this.

[0097] In some embodiments, the first information and the second information may be carried by the same signaling or by different signaling, and this application does not limit this.

[0098] In some embodiments, the terminal device may also obtain the first information and the second information through other devices besides the network device, and this application does not limit this.

[0099] In some embodiments, the interval between any two adjacent reference signal clusters in the at least one reference signal cluster satisfies the protocol agreement or network configuration, such as an interval of 2 time slots.

[0100] In some embodiments, the reference signal cluster in the at least one reference signal cluster may be a TRS cluster (TRSburst).

[0101] In some embodiments, the first receiving scheme includes: the terminal device does not expect any time unit used to transmit the first reference signal to be an uplink time unit.

[0102] Specifically, for example, the terminal device does not expect any time slot used to transmit the first reference signal to be a UL time slot, or the terminal device does not expect any symbol used to transmit the first reference signal to be a UL symbol. Typically, the network side needs to ensure that the time domain location of the triggered first reference signal transmission is not a UL time slot or a UL symbol. Even if the network side cannot guarantee this, the terminal device can adopt a protocol-independent approach; for example, the terminal device may not receive the first reference signal on an uplink time slot or uplink symbol.

[0103] In some embodiments, the first receiving scheme includes: the terminal device does not expect any time unit used to transmit the first reference signal to be a flexible time unit.

[0104] Specifically, for example, the terminal device does not expect any time slot used to transmit the first reference signal to be a flexible time slot, or the terminal device does not expect any symbol used to transmit the first reference signal to be a flexible symbol. Typically, the network side needs to ensure that the time domain location of the triggered first reference signal transmission is not a flexible time slot or flexible symbol. Even if the network side cannot guarantee this, the terminal device can adopt a protocol-independent approach; for example, the terminal device may not receive the first reference signal on a flexible time slot or flexible symbol.

[0105] In some embodiments, the first receiving scheme includes: the terminal device does not expect two consecutive time slots in a reference signal cluster to be uplink time slots. That is, in a reference signal cluster, at least one time slot is a downlink time slot. Even if the network cannot guarantee this, the terminal device can adopt a protocol-independent approach, for example, the terminal device may not receive the first reference signal in the uplink time slot.

[0106] In some embodiments, the first receiving scheme includes: the terminal device does not expect two consecutive time slots in a reference signal cluster to be flexible time slots. That is, in a reference signal cluster, at least one time slot is a downlink time slot. Even if the network side cannot guarantee this, the terminal device can adopt a protocol-free approach, for example, the terminal device does not receive the first reference signal on a flexible time slot.

[0107] In some embodiments, the first receiving scheme includes: the terminal device does not expect one of two consecutive time slots in a reference signal cluster to be a flexible time slot and the other to be an uplink time slot. That is, in a reference signal cluster, at least one time slot is a downlink time slot. Even if the network side cannot guarantee this, the terminal device can adopt a protocol-free approach, for example, the terminal device may not receive the first reference signal on the uplink time slot or the flexible time slot.

[0108] In some embodiments, the first receiving scheme includes: the terminal device does not expect that both consecutive time slots in a reference signal cluster contain uplink symbols or flexible symbols for transmitting the first reference signal. Even if the network cannot guarantee this, the terminal device may adopt a protocol-independent approach, for example, the terminal device may not receive the first reference signal on uplink symbols or flexible symbols.

[0109] In some embodiments, the first receiving scheme includes: the terminal device does not expect that both consecutive time slots in a reference signal cluster contain uplink symbols for transmitting the first reference signal. Even if the network cannot guarantee this, the terminal device can adopt a protocol-independent approach, for example, the terminal device may not receive the first reference signal on the uplink symbols.

[0110] In some embodiments, the first receiving scheme includes: in the at least one reference signal cluster, if the time unit used for transmitting the first reference signal is an uplink time unit or a flexible time unit, the terminal device does not receive the first reference signal.

[0111] Specifically, for example, in the at least one reference signal cluster, if the time slot used to transmit the first reference signal is an uplink time slot or a flexible time slot, the terminal device does not receive the first reference signal. Alternatively, in the at least one reference signal cluster, if the symbol used to transmit the first reference signal is an uplink symbol or a flexible symbol, the terminal device does not receive the first reference signal.

[0112] In some embodiments, in the at least one reference signal cluster, if the time unit used for transmitting the first reference signal is an uplink time unit or a flexible time unit, the network device does not send the first reference signal to the terminal device.

[0113] Specifically, for example, in the at least one reference signal cluster, if the time slot used to transmit the first reference signal is an uplink time slot or a flexible time slot, the network device does not transmit the first reference signal to the terminal device. Alternatively, in the at least one reference signal cluster, if the symbol used to transmit the first reference signal is an uplink symbol or a flexible symbol, the network device does not transmit the first reference signal to the terminal device.

[0114] In some embodiments, the first receiving scheme includes: in the at least one reference signal cluster, if the time unit used for transmitting the first reference signal is an uplink time unit, the terminal device does not receive the first reference signal.

[0115] Specifically, if the transmission of any first reference signal occupies an uplink time slot, the network device can cancel the transmission of that first reference signal in that time slot. Alternatively, if the transmission of any first reference signal occupies an uplink symbol, the network device can cancel the transmission of that first reference signal on that symbol. Or, if the transmission of any first reference signal occupies a flexible symbol, the network device can cancel the transmission of that first reference signal on that symbol. Alternatively, if the transmission of any first reference signal occupies a flexible time slot, the network device can cancel the transmission of that first reference signal in that time slot. These combinations also apply to the following schemes, which will not be elaborated further.

[0116] In some embodiments, the transmission of the first reference signal in a first time unit within the at least one reference signal cluster conflicts with uplink transmission. In this case, the terminal device receives the first reference signal in a second time unit following the first time unit. That is, the network device sends the first reference signal to the terminal device in the second time unit following the first time unit. In other words, the first reference signal, which should have been transmitted in the first time unit, is delayed until the second time unit.

[0117] In some embodiments, the first time unit may be a symbol or a time slot.

[0118] In some embodiments, the second time unit is the downlink time unit closest to the first time unit.

[0119] In some embodiments, the second time unit is determined based on a first time offset carried in the MAC CE used to activate the secondary cell. Optionally, the unit of the first time offset may be a time slot or a symbol.

[0120] In some embodiments, when the unit of the first time unit is a symbol, the second time unit is the one closest to the first time unit, and the pattern of the corresponding first reference signal does not contain a time slot where the transmission of the first reference signal conflicts with the uplink transmission.

[0121] In some embodiments, the pattern of at least one of the first reference signals may be agreed upon through a protocol.

[0122] In some embodiments, the transmission of the first reference signal in a time unit of a first reference signal cluster within the at least one reference signal cluster conflicts with uplink transmission. In this case, the terminal device receives the first reference signal on at least two consecutive downlink time slots following the first reference signal cluster. Correspondingly, the network device transmits the first reference signal to the terminal device on at least two consecutive downlink time slots following the first reference signal cluster. That is, the first reference signal, which should have been transmitted on the first reference signal cluster, is delayed until it is transmitted on the at least two consecutive downlink time slots.

[0123] In some embodiments, the at least two consecutive downlink time slots are the at least two consecutive downlink time slots closest to the first reference signal cluster.

[0124] In some embodiments, the at least two consecutive downlink time slots are determined based on a second time-domain offset carried in the MAC CE used to activate the secondary cell. Optionally, the unit of the second time-domain offset may be a time slot or a symbol.

[0125] In some embodiments, the at least one reference signal cluster includes a first reference signal cluster and a second reference signal cluster, and the second reference signal cluster is located after the first reference signal cluster. If the transmission of the first reference signal in a time unit of the first reference signal cluster conflicts with the uplink transmission, and the first reference signal corresponding to the conflicting time unit in the first reference signal cluster is delayed in transmission, then the second reference signal cluster is also delayed. Furthermore, the interval between the time unit in which the last first reference signal transmitted on the first reference signal cluster is located and the time unit in which the first first reference signal transmitted on the second reference signal cluster is located is greater than or equal to a first threshold. For example, the first threshold is two time slots.

[0126] In some embodiments, the first threshold is configured by the network device, or the first threshold is agreed upon by the protocol.

[0127] In some embodiments, the transmission of the first reference signal on a first symbol in the at least one reference signal cluster conflicts with uplink transmission. In this case, the terminal device receives the first reference signal in the time slot where the first symbol is located according to an adjusted pattern of the first reference signal, wherein the adjusted pattern of the first reference signal does not contain any symbols in which the transmission of the first reference signal conflicts with the uplink transmission. Accordingly, the network device transmits the first reference signal to the terminal device in the time slot where the first symbol is located according to the adjusted pattern of the first reference signal.

[0128] In some embodiments, the transmission of the first reference signal on a first symbol in the at least one reference signal cluster conflicts with uplink transmission, and there is no pattern of a first reference signal in the pattern of at least one first reference signal where the transmission of the first reference signal does not conflict with uplink transmission. In this case, the network device does not transmit the first reference signal to the terminal device on the first symbol; or, the network device transmits the first reference signal to the terminal device in a first time slot after the first symbol.

[0129] In some embodiments, the first time slot is the one closest to the first symbol, and the pattern of the corresponding first reference signal does not contain a time slot where the transmission of the first reference signal conflicts with the uplink transmission.

[0130] In some embodiments, the transmission of the first reference signal in a time unit within the at least one reference signal cluster conflicts with uplink transmission. In this case, the terminal device receives the first reference signal on a target downlink resource, wherein the target downlink resource is obtained by shifting the at least one reference signal cluster backward as a whole. Accordingly, the network device transmits the first reference signal to the terminal device on the target downlink resource. That is, the first reference signal, which should have been transmitted on the at least one reference signal cluster, is delayed until it is transmitted on the target downlink resource.

[0131] In some embodiments, the target downlink resource is the downlink resource that is closest to the at least one reference signal cluster and can transmit the first reference signal corresponding to the at least one reference signal cluster.

[0132] Specifically, for example, the at least one first reference signal burst includes two reference signal clusters. If a conflict occurs in the time slot or symbol of the first reference signal transmission, the first reference signal transmitted on the two reference signal clusters is delayed as a whole to the next nearest downlink resource location where the two reference signal clusters can be transmitted, and the interval between the two reference signal clusters after the offset remains unchanged.

[0133] In some embodiments, the target downlink resource is determined based on a third time-domain offset carried in the MAC CE used to activate the secondary cell. Optionally, the unit of the third time-domain offset may be a time slot or a symbol.

[0134] Therefore, in this embodiment, the first information is used to determine the transmission direction information, the second information is used to determine the time-domain location information of the first reference signal, the first reference signal is used to activate the carrier, and the time-domain location information of the first reference signal includes at least one reference signal cluster, with one reference signal cluster corresponding to two consecutive time slots. Thus, the terminal device can determine a first reception scheme for receiving the first reference signal based on the first information and the second information. This optimizes the reception method of the first reference signal and avoids conflicts between the transmission of the first reference signal and the transmission of other signals. Furthermore, this application further specifies the handling method after a conflict occurs between the transmission of the first reference signal and the uplink transmission; that is, this application can identify and handle the conflict between the transmission of the first reference signal and the uplink transmission, thereby allowing the terminal device to quickly activate the SCell based on the first reference signal.

If the transmission of the first reference signal in a time unit in the first reference signal cluster conflicts with the uplink transmission, and the first reference signal corresponding to the time unit in the first reference signal cluster where the conflict occurs is delayed in transmission, then the second reference signal cluster is also delayed. Furthermore, the interval between the time unit in which the last first reference signal transmitted on the first reference signal cluster is located and the time unit in which the first first reference signal transmitted on the second reference signal cluster is located is greater than or equal to a first threshold.
