Description

Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 6, 2024, with application number 202410172340.6 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method and a communication device. Background Art

[0003] Mobility management is a fundamental process in wireless communications. To maintain communication quality, a terminal can perform measurements based on network-side measurement configurations during mobility, triggering mobility management processes such as cell handover or cell reselection.

[0004] However, scheduling restrictions caused by measurements can cause terminals to not expect to transmit or receive data during the symbols being measured, which in turn reduces the probability of scheduling the scheduling unit (e.g., the timeslot or mini-slot containing the symbols being measured). Therefore, how to improve resource utilization to meet service transmission requirements remains to be studied. Summary of the Invention

[0005] The communication method and communication device provided in the embodiments of the present application can increase the probability of scheduling the time slot or micro-time slot where the symbol to be measured is located within the measurement time window, thereby ensuring the transmission delay and reliability of delay-critical services.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a communication method is provided, which can be applied to a terminal side, such as a terminal or a communication module in a terminal, or a circuit or chip responsible for a communication function in the terminal (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core). Taking the application of this method to a terminal as an example, the method includes: obtaining a first measurement configuration, the first measurement configuration is used to indicate a measurement time window, and the measurement time window includes a first time domain resource and a second time domain resource; performing data sending or receiving processing within a time range corresponding to the second time domain resource; and when the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, performing data sending or receiving processing within a time range corresponding to the first time domain resource, the first time domain resource overlaps with the time domain resource of the first physical channel, or the first time domain resource overlaps with the time domain resource corresponding to the discontinuous reception DRX timer triggered by the first physical channel.

[0008] Due to the embodiments of the present application, when the first time domain resources with scheduling restrictions included in the measurement time window overlap with the time domain resources of the first physical channel or the time domain resources corresponding to the DRX timer triggered by the first physical channel, the terminal can give priority to sending or receiving data within the time range corresponding to the first time domain resources based on the low priority of the first measurement configuration and / or the high priority of the first physical channel, thereby increasing the probability of the time slot or micro time slot where the first time domain resource is located being scheduled, and ensuring the transmission delay and reliability of delay-critical services.

[0009] In a second aspect, a communication method is provided, which can be applied to a network side, such as an access network device on the network side, a module in the access network device (such as a circuit, a chip or a chip system, etc.), or a logical node, a logical module or software that can realize all or part of the functions of the access network device. Taking the application of this method to an access network device as an example, the method includes: sending first configuration information, the first configuration information is used to indicate a measurement time window, the measurement time window corresponds to a first measurement configuration, and the measurement time window includes a first time domain resource and a second time domain resource; performing data sending or receiving processing within a time range corresponding to the second time domain resource; and when the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, performing data sending or receiving processing within a time range corresponding to the first time domain resource, the first time domain resource overlaps with the time domain resource of the first physical channel, or the first time domain resource overlaps with the time domain resource corresponding to the discontinuous reception DRX timer triggered by the first physical channel.

[0010] Among them, the technical effects of the second aspect can refer to the technical effects of the first aspect, and will not be repeated here.

[0011] In combination with the first or second aspect above, in a possible implementation, the priority of the first measurement configuration is low, specifically: the priority of the first measurement configuration is lower than that of data transmission, or the priority of the first measurement configuration is a first value, or the priority of the first measurement configuration is lower than a first threshold. That is, by setting a priority for the first measurement configuration to indicate that the priority of the first measurement configuration is low, the terminal can determine that the priority of measuring on the first time domain resource within the measurement time window indicated by the first measurement configuration is low, so that the terminal determines that data can be sent or received on the first time domain resource, thereby improving the resource utilization of the time slot or micro-time slot where the first time domain resource is located, and meeting the transmission delay requirements of delay-critical services.

[0012] In conjunction with the first or second aspect above, in one possible implementation, the priority of the first physical channel is high, specifically: the priority of the first physical channel is the second value, or the priority of the logical channel with the highest priority corresponding to the first physical channel is higher than the second threshold, or the priority of the MAC CE with the highest priority corresponding to the first physical channel is higher than the third threshold. In other words, the terminal can determine that the priority of the first physical channel is high based on the priority of the first physical channel, or the priority of the logical channel with the highest priority corresponding to the first physical channel is higher than the second threshold, or the priority of the MAC CE with the highest priority corresponding to the first physical channel is higher than the third threshold. Thus, the terminal does not change the method for determining the priority of the first physical channel, makes minimal changes to the protocol, and is easy to deploy.

[0013] In combination with the first aspect or the second aspect above, in a possible implementation, the first physical channel is used to schedule new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX inactivity timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX inactivity timer is defined by the duration of the DRX inactivity timer; the processing of data transmission or reception is performed within the time range corresponding to the first time domain resource, including: monitoring the second physical channel used to schedule new transmission of data within the time range corresponding to the first time domain resource. That is, when the priority of the first physical channel that triggers the start or restart of the DRX inactivity timer is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel used to schedule new transmission of data within the first time domain resource, thereby increasing the probability that the time slot or micro-time slot where the first time domain resource is located is scheduled.

[0014] In combination with the first aspect or the second aspect above, in a possible implementation, the first physical channel is used to schedule new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission downlink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission downlink timer is defined by the duration of the DRX retransmission downlink timer; the processing of sending or receiving data within the time range corresponding to the first time domain resource includes: monitoring the second physical channel used to schedule retransmission of the data within the time range corresponding to the first time domain resource. That is, when the first physical channel is a PDCCH used to schedule new transmission of downlink data and triggers the start or restart of the DRX retransmission downlink timer, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel used to schedule retransmission of the downlink data within the first time domain resource, thereby giving priority to ensuring the retransmission of the downlink data, thereby improving the reliability of service transmission.

[0015] In combination with the first aspect or the second aspect above, in a possible implementation, the first physical channel is used to carry new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission downlink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission downlink timer is defined by the duration of the DRX retransmission downlink timer; the processing of data transmission or reception is performed within the time range corresponding to the first time domain resource, including: monitoring the second physical channel used to schedule data retransmission within the time range corresponding to the first time domain resource. That is, when the first physical channel is a PDSCH used to carry new transmission of downlink data, and the DRX retransmission downlink timer is triggered to start or restart, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel used to schedule the retransmission of the downlink data within the first time domain resource, and can then preferentially guarantee the retransmission of the downlink data, thereby improving the reliability of service transmission.

[0016] In combination with the first or second aspect above, in a possible implementation, the first physical channel is used to schedule new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission uplink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission uplink timer is defined by the duration of the DRX retransmission uplink timer; the processing of sending or receiving data within the time range corresponding to the first time domain resource includes: monitoring the second physical channel used to schedule retransmission of data within the time range corresponding to the first time domain resource. That is, when the first physical channel is a PDCCH used to schedule new transmission of uplink data and triggers the start or restart of the DRX retransmission uplink timer, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel used to schedule retransmission of the uplink data within the first time domain resource, thereby giving priority to ensuring the retransmission of the uplink data, thereby improving the reliability of service transmission.

[0017] In combination with the first or second aspect above, in a possible implementation, the first physical channel is used to carry new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission uplink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission uplink timer is defined by the duration of the DRX retransmission uplink timer; the processing of sending or receiving data within the time range corresponding to the first time domain resource includes: monitoring the second physical channel used to schedule retransmission of data within the time range corresponding to the first time domain resource. That is, when the first physical channel is a PUSCH used to carry new transmission of uplink data, and the DRX retransmission uplink timer is triggered to start or restart, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel used to schedule retransmission of the uplink data within the first time domain resource, and can then give priority to ensuring the retransmission of the uplink data, thereby improving the reliability of service transmission.

[0039] To facilitate understanding of the technical solutions provided by the embodiments of this application, a brief introduction to the relevant technologies of this application is first given. The brief introduction is as follows:

[0040] First, latency-critical services:

[0041] In recent years, with the continuous development of fifth-generation (5G) communication systems, data transmission latency has continued to decrease, and transmission capacity has increased. 5G communication systems have gradually infiltrated multimedia services with strong real-time requirements and large data capacity, such as video transmission, cloud gaming (CG), and extended reality (XR). XR includes virtual reality (VR) and augmented reality (AR).

[0042] Cloud virtual reality (cloud VR) and cloud augmented reality (cloud AR) introduce the concepts and technologies of cloud computing and cloud rendering into VR or AR business applications. Leveraging high-speed and stable networks, cloud-based display and sound output are encoded and compressed and transmitted to terminals, enabling VR or AR business content and rendering to be moved to the cloud. VR or AR terminals can also meet requirements for lightweight and mobility.

[0043] Figure 1 is a schematic diagram of a communication network architecture based on cloud VR or cloud AR provided in an embodiment of the present application. As shown in Figure 1, the terminal can access the network element through the access network device, and then obtain VR or AR services from the cloud or edge cloud. For example, the communication link between terminal #1 and the access network device can be divided into downlink and uplink. Terminal #1 can send data to the access network device through the downlink, and then the access network device can forward the data to the cloud or edge cloud. Terminal #2 can receive service data from the cloud or edge cloud from the access network device through the uplink. It can be understood that Figure 1 is only an example, and the communication network architecture in Figure 1 can also include more terminals in addition to terminal #1 and terminal #2, and the embodiment of the present application does not specifically limit this.

[0044] Cloud XR services have strict latency requirements for the network. The motion-to-photons (MTP) latency must be less than 20 milliseconds (ms) to provide a partially immersive experience. Using asynchronous rendering technology, end-to-end interaction latency can be reduced to 70ms. Excluding server-side encoding and rendering latency and terminal decoding processing latency, the network transmission latency is only 20ms, with 10ms each for uplink and downlink transmission. In recent years, with the evolution of XR services, including the maturity of tactile Internet technology, network latency requirements have become even more stringent. For example, in remote control systems, to ensure high fidelity of touch and remote operation, the sampling rate of tactile information should be no less than 1 kilohertz (kHz), and the transmission latency requirement for one sample is 5ms, posing a huge challenge to 5G systems.

[0045] In addition, the above cloud XR service is only an example of a latency-critical service. Latency-critical services also include ultra-high reliability and ultra-low latency communication (URLLC) services, which are not specifically limited in the embodiments of the present application.

[0046] Second, discontinuous reception (DRX):

[0047] DRX is an important technology for terminal energy conservation. The principle of DRX is to enable the terminal to periodically monitor the physical downlink control channel (PDCCH) to reduce the duration of the terminal's PDCCH, thereby saving power. Among them, a DRX cycle can include a DRX on period (DRX on duration) and a DRX sleep period (also called a DRX opportunity). The DRX on period is the time range during which the terminal monitors the PDCCH, and the DRX sleep period is the time range during which the terminal enters sleep mode and does not monitor the PDCCH. In addition, the duration of the DRX on period is defined by the DRX continuous monitoring timer (drx-onDurationTimer).

[0048] FIG2 is a schematic diagram of a DRX-based PDCCH monitoring method according to an embodiment of the present application. As shown in FIG2 , during the DRX on-time period (i.e., the duration of the DRX continuous monitoring timer), the terminal monitors the PDCCH. During the DRX on-time period, if the terminal monitors the PDCCH for scheduling the physical downlink shared channel (PDSCH), it means that the terminal may continue to send and receive data for a period of time, so the DRX inactivity timer (drx-InactivityTimer) is started or restarted. During the DRX inactivity timer, the terminal is in an active state and continues to monitor the PDCCH.

[0049] Figure 3 is a second schematic diagram of a DRX-based PDCCH monitoring method according to an embodiment of the present application. As shown in Figure 3, when a terminal receives a PDCCH for scheduling a PDSCH, or a PDSCH for semi-persistent scheduling (SPS) (which is not accompanied by a transmitted PDCCH), and the terminal fails to decode the PDSCH, retransmission is required.

[0050] After the terminal feeds back a negative acknowledgement (NACK) of the hybrid automatic repeat request (HARQ), the terminal starts a DRX-HARQ round-trip downlink timer (drx-HARQ-RTT-TimerDL) for the HARQ process corresponding to the PDSCH that failed to decode. The duration of the DRX-HARQ round-trip downlink timer indicates the minimum duration that the terminal expects to receive the HARQ retransmission indication information, that is, during the timing of the DRX-HARQ round-trip downlink timer, the terminal does not expect to receive downlink retransmission indication information.

[0051] When the DRX-HARQ round-trip downlink timer expires, the terminal starts the DRX retransmission downlink timer (drx-RetransmissionTimerDL). The duration of the DRX retransmission downlink timer indicates the duration of time the terminal receives the downlink retransmission indication information. During the DRX retransmission downlink timer, the terminal is in the active state and monitors the PDCCH used to schedule PDSCH retransmissions.

[0052] FIG4 is a third schematic diagram of a method for monitoring PDCCH based on DRX provided in an embodiment of the present application. As shown in FIG4 , when a terminal receives a PDCCH for scheduling a physical uplink shared channel (PUSCH), or configuration information for a PUSCH with a configured grant (CG) (at this time, without accompanying transmission of a PDCCH), after the terminal sends the PUSCH, the terminal starts a DRX-HARQ round-trip uplink timer (drx-HARQ-RTT-TimerUL) for the HARQ process corresponding to the PUSCH. The duration of the DRX-HARQ round-trip uplink timer indicates the minimum duration for which the terminal expects to receive HARQ retransmission indication information, that is, during the timing of the DRX-HARQ round-trip uplink timer, the terminal does not expect to receive uplink retransmission indication information.

[0053] When the DRX-HARQ round-trip uplink timer expires, the terminal starts the DRX retransmission uplink timer (drx-RetransmissionTimerUL). The duration of the DRX retransmission uplink timer indicates the duration of time the terminal receives the uplink retransmission indication information. During the DRX retransmission uplink timer, the terminal is in the active state and monitors the PDCCH used to schedule PUSCH retransmissions.

[0054] Third, measure:

[0055] Measurements can be divided into intra-frequency measurement and inter-frequency measurement. Intra-frequency measurement means that the signals of the cell where the terminal is currently located (or called the source cell) and the target cell to be measured are on the same carrier frequency (center frequency). Inter-frequency measurement means that the signals of the cell where the terminal is currently located and the target cell are not on the same carrier frequency. The signal to be measured can be a synchronization signal / physical broadcast channel block (SSB) or a channel state information reference signal (CSI-RS).

[0056] It can be understood that the 3rd Generation Partnership Project (3GPP) specifies the time-frequency resources in the 5G communication system (or new radio (NR) system) and the time-frequency resource locations of the above signals. The following first introduces the time-frequency resources of the NR system.

[0057] 3.1. Time and frequency resources of NR system:

[0058] Time-frequency resources may include time domain resources and frequency domain resources. Among them, in order to meet the demand for communication traffic, in the frequency domain, the NR system can support a larger frequency range (FR) and system bandwidth. For example, for low frequency bands below 6 GHz, such as FR1 (410 MHz to 7125 MHz), the maximum system bandwidth supported by the NR system is 100 MHz. For another example, for high frequency bands above 6 GHz up to the millimeter wave band, such as FR2 including FR2-1 (24250 MHz to 52600 MHz) and FR2-2 (52600 MHz to 71000 MHz), the maximum system bandwidth supported by the NR system is 400 MHz. It can be understood that in addition to the above-mentioned FR1, FR2, and FR2-2, FR can also be other frequency ranges supported in future next-generation communication systems (such as the sixth generation (6G) communication system), and the embodiments of the present application do not specifically limit this.

[0059] In addition, time domain resources and frequency domain resources are related to the transmission scheme of the NR system. Among them, the uplink transmission scheme and downlink transmission scheme of the NR system can use orthogonal frequency division multiplexing (OFDM) technology. The minimum frequency domain resource in the NR system can be 1 subcarrier, and the minimum time domain resource can be 1 OFDM symbol.

[0060] It can be understood that any two subcarriers within an OFDM symbol are orthogonal, and thus the duration of the OFDM symbol (i.e., the duration of the OFDM symbol) is inversely proportional to the subcarrier space (SCS). The subcarriers are located within the carrier in which the NR system operates, and the number of subcarriers is determined by the subcarrier space (SCS) and the system bandwidth corresponding to the carrier.

[0061] Furthermore, the complexity of wireless channels can create multipath effects, leading to inter-symbol interference (ISI). Adding a cyclic prefix (CP) to OFDM symbols is equivalent to inserting a guard interval between different OFDM symbols, thereby reducing ISI. CPs can be classified into normal CPs and extended CPs.

[0062] It should be understood that the NR system can be configured with different SCSs to accommodate the different FRs described above. For example, for the low-frequency band FR1, a smaller SCS is used to avoid excessive CP time domain overhead. For another example, for the high-frequency bands FR2 and FR2-2, a larger SCS is used to avoid significant inter-subcarrier interference caused by Doppler frequency shift in the high frequency band.

[0063] An exemplary transmission parameter set supported by the NR system is shown in Table 1. In Table 1, the first column is the specific value of the SCS configuration μ, the second column is the specific value of the SCS, and the third column is the specific type of the CP.

[0064] Table 1

[0065] Among them, for SCS of 15kHz, the OFDM symbol time length can be approximately 66.67μs; for SCS of 30kHz, the OFDM symbol time length can be approximately 33.33μs; for SCS of 60kHz, the OFDM symbol time length can be approximately 16.67μs; for SCS of 120kHz, the OFDM symbol time length can be approximately 8.88μs; for SCS of 240kHz, the OFDM symbol time length can be approximately 4.17μs.

[0066] It is understood that the specific lengths of the regular CP and the extended CP can be found in the provisions of the relevant 3GPP protocols, which will not be repeated here.

[0067] In addition, Table 1 is only an example. The SCS configuration μ can also take a value of 5 (SCS is 480kHz) or 6 (SCS is 960kHz). The embodiments of the present application do not specifically limit this.

[0068] It should be understood that in the time domain, the NR system can be transmitted in units of radio frames. Among them, a radio frame can include multiple subframes, and each subframe can include multiple time slots. That is, the NR system can include time domain resources of different granularities such as radio frames, subframes, time slots, and OFDM symbols.

[0069] For example, each radio frame has a duration of 10 ms. Each radio frame may consist of 10 subframes each having a duration of 1 ms. The 10 subframes within a radio frame may be arranged sequentially. For example, the 10 subframes within a radio frame may be arranged in ascending chronological order as: subframe #0 to subframe #9. For another example, the 10 subframes may be arranged in descending chronological order as: subframe #9 to subframe #0. This embodiment of the present application does not specifically limit the subframe ordering method.

[0070] In addition, the above subframe numbers are only exemplary. For example, the numbering may start with 1. For example, 10 subframes in a radio frame may be represented as: subframe #1 to subframe #10.

[0071] It can be understood that for SCS configuration μ, time slots can be numbered in ascending order within a subframe. Arranged, and can be numbered in ascending order within a radio frame In a time slot there are consecutive OFDM symbols, It is related to the CP type used by OFDM symbols. As shown in Table 2, no matter how many SCSs there are, a time slot includes 14 OFDM symbols. As can be seen from Table 3, when the SCS is 60kHz, one time slot includes 12 OFDM symbols.

[0072] In addition, the time slot in a subframe The time domain starting position is the same as the OFDM symbol in the same subframe The time domain starting positions of OFDM symbols are aligned. For example, when a time slot includes 14 OFDM symbols, the OFDM symbols can be sorted in ascending time order as: OFDM symbol #0 to OFDM symbol #13, where the time domain starting position of OFDM symbol #0 is the same as the time domain starting position of the time slot.

[0073] Table 2

[0074] Table 3

[0075] It should be understood that Table 2 and Table 3 are only examples. For example, when the value of μ is 5, a subframe includes 32 time slots; for another example, when the value of μ is 6, a subframe includes 64 time slots. The embodiments of the present application do not specifically limit this.

[0076] In addition, in service scheduling, the granularity (or scheduling unit) of PDSCH or PUSCH scheduling can be a time slot or a mini-time slot. The time length of a mini-time slot can be a portion of an OFDM symbol within a time slot. For example, the time length of a downlink mini-time slot can be 2, 4, or 7 OFDM symbols, and the time length of an uplink mini-time slot can be any time length within 1 to 14 OFDM symbols.

[0077] It should be understood that for ease of expression, OFDM symbols will be expressed as symbols below, which will be uniformly explained here and will not be repeated below.

[0078] It can be understood that according to the aforementioned description of OFDM, the minimum granularity of frequency domain resources is one subcarrier, and the number of subcarriers can measure the size of frequency domain resources. In the NR system, frequency domain resources can be divided into resource elements (RE), resource blocks (RB), and bandwidth parts (BWP).

[0079] For RE: a subcarrier in the frequency domain and a symbol in the time domain can be defined as RE. RE is the smallest granularity resource in the physical layer.

[0080] Regarding resource allocation (RB): In the frequency domain, regardless of the subcarrier spacing, 12 consecutive subcarriers can be defined as one RB. The larger the SCS, the greater the actual bandwidth corresponding to one RB. It should be understood that in the physical layer, an RB can be called a physical resource block (PRB).

[0081] Regarding BWP: Taking into account the limitations of terminal capabilities and energy-saving requirements, the NR system allows the terminal to operate in a part of the system bandwidth, namely BWP. Alternatively, BWP can be part of the bandwidth corresponding to a carrier supported by a cell. For example, a cell covered by a network device (such as a next-generation radio access network (NG-RAN) device in the NR system) supports two carriers (carrier #1 and carrier #2). The cell allocates 40MHz bandwidth to carrier #1 and 60MHz bandwidth to carrier #2 respectively. BWP can be 20MHz bandwidth in the 40MHz bandwidth corresponding to carrier #1, and the terminal can work only on BWP. It can be understood that a BWP can include multiple RBs, that is, the size of BWP can be measured by the number of RBs. It can also be understood that the size of frequency domain resources can also be expressed by bandwidth. For example, for an SCS of 15kHz, the bandwidth of the RB is 12×15kHz=180kHz.

[0082] It should be understood that in the NR system, after the terminal accesses the network through the initial access process, the network can configure the working BWP for the terminal through high-layer signaling. Each terminal can be configured with 1 to 4 BWPs, but only one BWP is active at any time. Except for radio resource management (RRM) measurements, the terminal only sends and receives data on the active BWP.

[0083] It can be understood that in the embodiments of the present application, "carrier", "carrier frequency", and "frequency point" can be expressed interchangeably and are explained uniformly here and will not be repeated below.

[0084] In addition, in the embodiments of the present application, "number" and "index" have the same meaning. In other words, "number" and "index" can be used interchangeably, and are described here uniformly and will not be repeated below.

[0085] It is also understood that in the embodiments of the present application, an index may correspond to an identity (ID). For example, a timeslot index may correspond to an identity of a time domain resource; a cell index may correspond to a cell identity; a carrier index may correspond to a carrier identity; an activated BWP index may correspond to an activated BWP identity, etc. These are all described here and will not be further elaborated below.

[0086] Taking SSB as an example, combined with the above introduction to time domain resources and frequency domain resources, the position of SSB in the time domain resources is further introduced.

[0087] 3GPP stipulates that the resource size of each SSB transmitted by a cell is fixed. For example, each SSB occupies four consecutive symbols in the time domain and 20 RBs in the frequency domain. In addition, due to the significant propagation loss of high-frequency carriers, beamforming is required to increase the coverage distance of wireless signals. Furthermore, since each beam has a limited coverage angle (i.e., a narrow beamwidth), cells can periodically transmit SSBs through beam scanning to ensure that terminals outside the beam coverage area can reliably receive signals from the cell.

[0088] It can be understood that the cell sending SSB can be understood as the access network equipment covering the cell sending SSB. This is a unified explanation here and will not be repeated below.

[0089] FIG5 is a schematic diagram of an SSB position distribution provided by an embodiment of the present application. As shown in FIG5 , the multiple SSBs transmitted to complete a beam scan constitute an SSB burst set. The number N of SSBs contained in an SSB burst set can be 4, 8, or 64. The SSB burst set needs to be transmitted within 5 ms of a half-frame. The transmission period of the SSB burst set can be {5, 10, 20, 40, 80, 160} ms. The transmission period of the SSB burst set can be indicated by the system information block (SIB) 1.

[0090] In addition, the number of SSBs in an SSB burst set and the SSB symbol position (e.g., time domain position) are related to the SSB frequency and SCS. For example, 3GPP defines the number of SSBs in an SSB burst set and the time domain position distribution of SSB symbols under Cases A to G.

[0091] To facilitate understanding of the time domain position distribution of SSB symbols in an SSB burst set, examples A to C are introduced below, taking the time domain starting position of the SSB symbol located in subframe #0 (numbering starting from 0) in a wireless frame as an example.

[0092] In addition, the subframes, time slots, and symbols in the following examples are numbered starting from 0, which will be uniformly explained here and will not be repeated.

[0093] Example A:

[0094] In Example A, the SCS is 15 kHz, and one subframe contains one time slot. The SSB symbol starts at symbol #2 and symbol #8 in the time domain of each time slot, meaning two SSBs can be transmitted in each time slot. When the carrier frequency is less than or equal to 3 GHz, the number of SSBs in an SSB burst set is four, namely SSB #0 to SSB #3. As shown in (a) in Figure 5, SSB#0 to SSB#3 are distributed in the first two subframes of the five subframes (subframe #0 to subframe #4): subframe #0 and subframe #1. Every two SSBs in SSB#0 to SSB#3 are distributed in one subframe. The time domain position of SSB#0 is symbol #2 to symbol #5 in subframe #0, and the time domain position of SSB#1 is symbol #8 to symbol #11. The time domain position distribution of SSB#2 in subframe #1 is similar to that of SSB#0, and the time domain position distribution of SSB#3 in frame #1 is similar to that of SSB#1, which will not be repeated here.

[0095] When the carrier frequency is greater than 3 GHz, the number of SSBs in an SSB burst set is 8, namely SSB#0 to SSB#7. As shown in Figure 5(b), SSB#0 to SSB#7 are distributed in the first 4 subframes (subframe#0 to subframe#4) of the 5 subframes: subframe#0 to subframe#3. Among them, every two SSBs in SSB#0 to SSB#7 are distributed in a subframe. The time domain position distribution of each two SSBs in a subframe is similar to that in Figure 5(a) and is not repeated here.

[0096] Example B:

[0097] In Example B, the SCS is 30 kHz, and a subframe contains two time slots. The time domain starting positions of the SSB symbols in the first time slot are symbols #4 and #8 of the time slot, and the time domain starting positions of the SSB symbols in the second time slot are symbols #2 and #6 of the time slot. That is, two SSBs can be sent in each of the two time slots. When the carrier frequency is less than or equal to 3 GHz, the number of SSBs in an SSB burst set is 4, namely SSB #0 to SSB #3. As shown in Figure 5(c), SSB#0 to SSB#3 are distributed across two time slots (time slot #0 and time slot #1) in the first subframe (i.e., subframe #0) among the five subframes (subframe #0 to subframe #4). Every two SSBs in SSB#0 to SSB#3 are distributed within one time slot. The time domain position of SSB#0 is symbols #4 to #7 in time slot #0, the time domain position of SSB#1 is symbols #8 to #11 in time slot #0, the time domain position of SSB#2 is symbols #2 to #5 in time slot #1, and the time domain position of SSB#3 is symbols #6 to #9 in time slot #1. It can be understood that, in conjunction with Figure 5(a) and Figure 5(c), the difference between the two is that in Figure 5(a), there is a symbol interval between the two SSBs in each time slot, while in Figure 5(b), there is no interval between the two SSBs in each time slot.

[0098] When the carrier frequency is greater than 3 GHz, the number of SSBs in an SSB burst set is 8, namely SSB#0 to SSB#7. As shown in Figure 5(d), SSB#0 to SSB#7 are distributed in the first two subframes of the five subframes (subframe#0 to subframe#4): subframe#0 and subframe#1. Each two SSBs in SSB#0 to SSB#7 are distributed in one time slot. The time domain position distribution of the two SSBs in each time slot is similar to that in Figure 5(c) and is not repeated here.

[0099] Example C:

[0100] Example C is similar to Example B, and the SCS is 30kHz. The difference is that the time domain position distribution of the two SSBs in a time slot is similar to (a) in Figure 5. The time domain starting positions of the two SSBs are respectively located at symbol #2 and symbol #8 in the time slot, and there are 2 symbols between the two SSBs. For details, please refer to (e) and (f) in Figure 5, and no further details will be given.

[0101] It should be understood that Example D corresponds to an SCS of 120kHz, a carrier frequency within the FR2 range, 8 time slots in one subframe, 76 SSBs in one SSB burst set, and the time domain positions occupied by the 4 SSBs in every 2 time slots are similar to (c) in Figure 5. The 76 SSBs occupy a total of 5 subframes.

[0102] Example E corresponds to an SCS of 240 kHz, a carrier frequency within the FR2-1 range, 16 time slots in a subframe, 72 SSBs in an SSB burst set, and the time domain positions occupied by the 8 SSBs in every 4 time slots are shown in (g) of Figure 5. The 72 SSBs occupy a total of 3 subframes. As shown in (g) of Figure 5, within time slots #0 to #3, SSBs #1 to #3 occupy 16 consecutive symbols in time slots #0 and #1, SSBs #4 to #7 occupy 16 consecutive symbols in time slots #2 and #3, and there is an interval of 8 symbols between the 16 consecutive symbols occupied by SSBs #1 to #3 and the 16 consecutive symbols occupied by SSBs #4 to #7. Similarly, the 16 consecutive symbols occupied by SSB#8 to SSB#11 in subsequent time slots #4 and #5 are similar in time domain distribution to the 16 consecutive symbols occupied by SSB#1 to SSB#3, and the details are not repeated here. It can be understood that there is a gap of 16 symbols between SSB#4 to SSB#7 and SSB#8 to SSB#11.

[0103] Example F corresponds to an SCS of 480kHz and a carrier frequency in the FR2-2 range. A subframe includes 32 time slots, and the number of SSBs in an SSB burst set is 64. The time domain positions occupied by the two SSBs in each time slot are shown in (h) in Figure 5. The 64 SSBs occupy a total of 1 subframe, SSB#0 occupies symbols #2 to #5 in time slot #0, and SSB#1 occupies symbols #9 to #12 in time slot #0. In addition, there are 3 symbols between any two adjacent SBBs in this SSB.

[0104] Example G corresponds to an SCS of 960kHz, a carrier frequency in the FR2-2 range, 64 time slots in one subframe, 64 SSBs in one SSB burst set, and the time domain positions occupied by the two SSBs in each time slot are shown in (h) in Figure 5. The 64 SSBs occupy a total of 32 time slots in one subframe.

[0105] It can be understood that the SSB time domain position distribution diagram shown in Figure 5 is only an example. The time domain position of SSB can also be subframe #5, etc. The SSB time domain position distribution depends on the frequency of SSB, SCS, and the actual implementation of the access network equipment. The embodiments of the present application do not make specific limitations on this.

[0106] In addition, as shown in FIG5 , SSB is not transmitted at all time sequences within a beam scanning cycle. For example, SSB is not transmitted in subframes #2 to #4 of (a) in FIG5 . If the terminal searches for and measures SSB at all time sequences, power will be wasted.

[0107] To reduce the power consumption of the terminal, the access network device can configure the SSB-based measurement timing configuration (SMTC) for the terminal to measure the SSB. The SMTC indicates the measurement time window for the terminal to measure the SSB, so that the terminal can perform SSB measurement within the measurement time window, and not perform SSB measurement outside the measurement time window, thereby reducing power consumption.

[0108] The following is an introduction to SMTC.

[0109] 3.2、SMTC:

[0110] The SMTC may include one or more of the duration of the measurement time window (also called the SMTC length), the period of the measurement time window (also called the SMTC period), or an offset (SMTC offset). The SMTC period and / or SMTC offset may be used to determine the time domain starting position of the measurement time window, and the SMTC length may be used to determine the duration of the measurement window.

[0111] In addition, SMTC is a frequency-level configuration, that is, the SMTC is associated with the cell's frequency. For example, in the information element (IE) measurement object NR (MeasObjectNR), which includes the SSB frequency sub-IE and the configuration IE corresponding to the SMTC, the value of the SSB frequency field is the absolute radio-frequency channel number (ARFCN) NR value (ARFCN-value NR).

[0112] It should be understood that the protocol defines that SMTC may include SMTC1. Optionally, SMTC may also include SMTC2. Among them, the configuration information element corresponding to SMTC1 is SSB-MTC, which includes two sub-information elements: period and offset (periodicityAndOffset), and duration (duration). The period and offset sub-information element is used to indicate the time domain starting position of the SMTC period and the measurement time window, and the duration sub-information element is used to indicate the SMTC length. In addition, the SMTC period can be {5, 10, 20, 40, 80, 160} ms. The value of the SMTC offset is between 0 and (SMTC period-1) ms with a granularity of 1ms. The SMTC length can be {1, 2, 3, 4, 5} ms. For example, when the SMTC period is 5ms, the value of the SMTC offset can be 0ms, 1ms, 2ms, 3ms or 4ms, and the value of the SMTC length can be 1ms, 2ms, 3ms, 4ms or 5ms.

[0113] For example, for the SSB time domain position distribution shown in (a) in Figure 5, the time domain starting position of the measurement time window can be the time domain starting position of subframe #0 in Figure 5, the SMTC length can be 2ms, and then the measurement time window can include subframe #0 and subframe #1, so that the terminal does not need to search and measure SSB on subframe #2 to subframe #4, avoiding wasting the terminal's power consumption.

[0114] The configuration information element corresponding to SMTC2 is SSB-MTC2, and SMTC2 is used to flexibly configure differentiated SMTC periods for specified neighboring cells. For example, by configuring a list of SMTC periods that can be used on a frequency point through SMTC2, the access network equipment can inform the terminal through configuration which SMTC period each neighboring cell on the frequency point should use. If a cell does not explicitly indicate the SMTC period it uses, it should use an SMTC period with a longer period. In addition, if SMTC2 is not configured, it is equivalent to all neighboring cells using the SMTC period configured by SMTC1; if SMTC2 is configured, a period smaller than the period indicated by SMTC1 is selected from the multiple SMTC periods configured by SMTC2.

[0115] Fourth, scheduling restrictions:

[0116] Scheduling restriction means that when the terminal is measuring, it is not expected to send or receive data. Sending or receiving data can refer to: sending physical uplink control channel (PUCCH) or PUSCH or sounding reference signal (SRS), or receiving PDCCH or PDSCH or tracking reference signal (TRS) or CSI-RS. For example, 3GPP defines that when a terminal performs measurement in the FR2 frequency band and there is no measurement gap (i.e., the frequency of the SSB to be measured is within the terminal's active BWP, i.e., intra-frequency measurement), due to the synchronization signal reference signal received power (SS-RSRP) or synchronization signal to interference plus noise ratio (SS-SINR) measurement of the FR2 intra-frequency cell, the scheduling restrictions that exist are as follows:

[0117] A. If the higher-layer parameter deriveSSB-IndexFromCell is enabled, the terminal does not expect to transmit PUCCH, PUSCH, or SRS, or receive PDCCH, PDSCH, TRS, or CSI-RS on the following symbols:

[0118] The SSB symbol to be measured, and within the measurement time window indicated by SMTC (or called SMTC window): K data symbols before each consecutive SSB symbol to be measured, and K data symbols after each consecutive SSB symbol to be measured.

[0119] B. If deriveSSB-IndexFromCell is not enabled and the SCS used by data symbols and SSB symbols is less than 960 kHz, the terminal does not expect to send PUCCH or PUSCH or SRS on all symbols within the SMTC window length, or receive PDCCH or PDSCH or TRS or CSI-RS.

[0120] C. If deriveSSB-IndexFromCell is not enabled and the SCS used by data symbols or SSB symbols is 960 kHz, the terminal does not expect to transmit PUCCH, PUSCH, or SRS, or receive PDCCH, PDSCH, TRS, or CSI-RS for channel quality indication (CQI) on the following symbols:

[0121] The SSB symbol to be measured, and within the SMTC window: K' data symbols before each consecutive SSB symbol to be measured, and K' data symbols after each consecutive SSB symbol to be measured.

[0122] It can be understood that the above introduction to scheduling restrictions is only about the same-frequency measurement of SS-RSRP or SS-SINR in the FR2 frequency band. Scheduling limits also exist in other frequency bands and other types of measurements. For example, in the time division duplex (TDD) band in the FR1 frequency band, the terminal does not expect to send PUCCH or PUSCH or SRS on the following symbols: the SSB symbol to be measured, and in the SMTC window: 1 data symbol before each continuous SSB symbol to be measured, and 1 data symbol after each continuous SSB symbol to be measured. For details, please refer to the relevant instructions of the 3GPP protocol, which will not be repeated here.

[0123] In addition, similar to SSB, CSI-RS measurement configuration is assigned to the terminal in the form of CSI-RS resources or resource sets, and CSI-RS measurement is also subject to scheduling restrictions. For example, when a terminal performs intra-frequency measurement for Layer 3 (L3) mobility management in FR2 based on CSI-RS, the terminal does not expect to transmit PUCCH, PUSCH, or SRS on the configured CSI-RS symbols, or receive PDCCH, PDSCH, TRS, or CSI-RS.

[0124] Based on the above explanations on the scheduling restrictions caused by measurements, since each continuous SSB symbol to be measured in the SMTC window and the 2K symbols adjacent to each continuous SSB symbol to be measured are not expected to be used for service data transmission, this will lead to a reduction in the schedulable resources in the time slot where the SSB symbol to be measured in the SMTC window is located, which is not suitable for the transmission of most service data. This will reduce the probability of the scheduling unit (time slot or micro time slot) where the continuous SSB symbol to be measured is located being scheduled, resulting in a waste of resources and affecting the transmission delay of delay-critical services.

[0125] For example, in the XR service, the data arrival period of XR is a non-integer, such as 30 frames per second (FPS), 60FPS, or 90FPS XR videos, whose frame arrival periods are 1 / 30s, 1 / 60s, and 1 / 90s respectively. The frame arrival period of the XR service cannot match the SMTC period, and thus the time domain resources used for XR service transmission and the measurement time domain resources within the SMTC window at least partially overlap. Furthermore, due to scheduling restrictions, the scheduling unit where the measurement time domain resources within the SMTC window are located will not be scheduled for the transmission of XR service data, which will cause the XR service data to be transmitted later, reducing the resource utilization of the scheduling unit, and increasing the transmission delay of the XR service, making it impossible to guarantee the reliability of XR service transmission.

[0126] The above problem is exemplarily described below with reference to the schematic diagram shown in FIG6 .

[0127] Figure 6 is a schematic diagram of the impact of scheduling restrictions on XR service transmission provided by an embodiment of the present application. Assume that the arrival period of the service frame is 16.67ms (60FPS), the position distribution of the SSB is the SSB position distribution shown in (b) of Figure 5, the SMTC length is 5ms, and the SMTC period is 40ms. As shown in (a) of Figure 6, in the absence of scheduling restrictions, the XR service can transmit a total of 6 service frames: service frame #1 to service frame #6, and the SMTC configured by the network side for the terminal includes SMTC window #1 to SMTC window #3. It can be seen that the time domain resources corresponding to service frame #4 and service frame #6 at least partially overlap with the time domain resources corresponding to SMTC, which are explained separately below.

[0128] For service frame #4, the time domain resources occupied by service frame #4 include the time domain resources occupied by SMTC window #2. Therefore, due to scheduling restrictions, the multiple scheduling units where the terminal's measurement time domain resources within SMTC window #2 are located will not be scheduled to transmit service frame #4, reducing the utilization rate of the multiple scheduling units, which will cause the transmission of service frame #4 to be delayed, affecting the transmission delay and reliability.

[0129] As shown in (b) of Figure 6, the time domain resources occupied by service frame #6 during transmission include the first two symbols of subframe #0 (i.e., one time slot). SSB #1 within SMTC window #3 occupies symbols #2 to #5 within time slot #0. Consequently, the overlapping time domain resources between SMTC window #3 and service frame #6 are: the two consecutive symbols preceding SSB #1, i.e., symbols #0 and #1 within subframe #0. It can be understood that due to scheduling restrictions, in the FR1 frequency band, the one data symbol preceding the consecutive SSB symbols to be measured (i.e., symbol #1) and the one data symbol following the consecutive SSB symbols to be measured (i.e., symbol #6) are restricted from data transmission. This, in turn, prevents service frame #6 from being scheduled in subframe #0, causing delayed transmission of service frame #6, impacting transmission latency and reliability.

[0130] Furthermore, referring to (b) in Figure 6 , due to scheduling restrictions, the only symbols that can be scheduled in subframe #0 are symbol #0 and symbol #13, and subframes #1 to #3 are the same as subframe #0. This means that the remaining time domain resources in SMTC window #3 are only suitable for scheduling services with smaller data volumes, and are not suitable for scheduling services with more than three symbols. This results in a low probability of being scheduled, which does not meet the transmission requirements of the service.

[0131] Based on the above problems, the embodiment of the present application proposes the following technical solution, which can improve resource utilization when scheduling restrictions are caused by measurement. The technical solution in the embodiment of the present application is described below in conjunction with the drawings in the embodiment of the present application.

[0132] In order to facilitate understanding of the embodiments of the present application, the following explanations are made before introducing the embodiments of the present application.

[0133] 1.

[0134] 2. "Predefined," "predefined," "preconfigured (or pre-configured)," and "protocol agreement" may be used interchangeably, and pre-definition may be achieved by pre-saving corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal or access network device).

[0135] 3. The “protocol” involved in the embodiments of the present application may refer to a standard protocol in the field of communications, such as the long term evolution (LTE) protocol, the NR protocol, wireless fidelity (Wi-Fi), and related protocols used in future communication systems (such as 6G communication systems). The embodiments of the present application are not limited to this.

[0136] 4. In the embodiments of the present application, descriptions such as “when…”, “in the case of…”, “if” and “if” all refer to the fact that the device (such as a terminal or access network device) will perform corresponding processing under certain objective circumstances.

[0137] 5. In the embodiments of the present application, "sending information" can be understood as one device (or apparatus) sending information to another device (or apparatus), or as one logical module within a device sending information to another logical module. For example, "an access network device sending information" can be understood as an access network device sending information to another device (such as a terminal), or as logical module 1 within an access network device sending information to logical module 2 within the access network device.

[0138] In addition, in the embodiments of the present application, "receiving information" can be understood as one device (or apparatus) receiving information from another device (or apparatus), or it can also be understood as a logic module within a device receiving information from another logic module. For example, "an access network device receiving information" can be understood as the access network device receiving information from another device (such as a terminal), or it can be understood as logic module 1 in the access network device receiving information from logic module 2 in the access network device.

[0139] In addition, "sending information to...(terminal)" can be understood as the destination of the information being the terminal, and may include sending information directly or indirectly to the terminal. "Receiving information from...(access network device)" or "receiving information from...(access network device)" can be understood as the source of the information being the access network device, and may include receiving information directly or indirectly from the access network device. The information may be processed as necessary between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0140] 6. In the description of the embodiments of the present application, unless otherwise specified, the "and / or" in the embodiments of the present application indicates that there may be three relationships.

Moreover, "at least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different. At the same time, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions.

[0141] The embodiments of the present application can be applicable to LTE systems or NR systems, systems with hybrid LTE and NR networks, vehicle to everything (V2X) systems, device-to-device (D2D) systems, machine to machine (M2M) communication systems, Internet of Things (IoT) systems (such as narrowband Internet of Things (NB-IoT) systems), Wi-Fi systems, non-terrestrial networks (NTN) systems, 6G systems, and other next-generation communication systems. Alternatively, the communication system may also be an open radio access network (O-RAN or ORAN) or a cloud radio access network (CRAN), without limitation.

[0142] It can be understood that the embodiments of the present application can be applicable to a variety of different services, such as enhanced mobile broadband (eMBB), URLLC, massive machine type communication (mMTC), immersive communication, massive communication, ubiquitous connections, integrated artificial intelligence and communication, or integrated sensing and communication, etc. In order to meet the further requirements of the above-mentioned different services for transmission delay, reliability, and coverage, higher resource utilization is required.

[0143] In addition, the communication architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of the communication architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0144] Figure 7 is a possible, non-limiting system diagram provided by an embodiment of the present application. As shown in Figure 7, the communication system 70 includes a RAN 700 and a core network (CN) 800. The RAN 700 includes at least one access network device (such as 710a and 710b in Figure 7, collectively referred to as 710) and at least one terminal (720a-720j in Figure 7, collectively referred to as 720). The RAN 700 may also include other access network devices, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 7). The terminal 720 is connected to the access network device 710 via wireless means. The access network device 710 is connected to the core network 800 via wireless or wired means. The core network device in the core network 800 and the access network device 710 in the RAN 700 can be different physical devices, or they can be the same physical device that integrates the core network logical functions and the wireless access network logical functions.

[0145] The RAN 700 may be a 3GPP-related cellular system, such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 700 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (Wi-Fi) system. The RAN 700 may also be a communication system that integrates two or more of the above systems.

[0146] Access network equipment 710, sometimes also referred to as radio access network equipment, RAN node, RAN entity, or access node, constitutes part of a communication system and facilitates wireless access for terminals. Multiple access network equipment 710 in communication system 70 can be nodes of the same type or different types. In some scenarios, the roles of access network equipment 710 and terminal 720 are relative. For example, network element 720i in Figure 7 can be a helicopter or drone, which can be configured as a mobile base station. For terminal 720j accessing RAN 700 via network element 720i, network element 720i is a base station; however, for base station 710a, network element 720i is a terminal. Access network equipment 710 and terminal 720 are sometimes referred to as communication devices. For example, network elements 710a and 710b in Figure 7 can be understood as communication devices with base station functions, and network elements 720a-720j can be understood as communication devices with terminal functions.

[0147] In one possible scenario, the access network device may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a Wi-Fi system. The access network device may be a macro base station (such as 710a in Figure 7), a micro base station or an indoor station (such as 710b in Figure 7), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the access network device may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in V2X technology may be a road side unit (RSU). All or part of the functions of the access network device in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The access network device may also be provided with a communication module, circuit or chip that performs the corresponding communication function. The access network device may also be configured with program instructions for executing corresponding communication functions and corresponding program instructions. The network device in the embodiment of the present application may also be a logical node, logical module or software that can realize all or part of the functions of the access network device.

[0148] In another possible scenario, multiple access network devices collaborate to assist the terminal in achieving wireless access, and different access network devices respectively implement part of the functions of the base station. For example, the access network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0149] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in the embodiments of the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0150] A terminal can be a device or module that accesses the above-mentioned communication system and has corresponding communication functions. A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as D2D, V2X communication, MTC, IoT, virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, transport vehicle with wireless communication function, communication module, etc. The embodiments of the present application do not limit the device form of the terminal. The terminal is usually provided with a communication module, circuit or chip that performs the corresponding communication function. The terminal is also configured with program instructions for performing the corresponding communication function.

[0151] An embodiment of the present application provides a communication method. Through this method, when the first time domain resources with scheduling restrictions included in the measurement time window overlap with the time domain resources of the first physical channel or the time domain resources corresponding to the DRX timer triggered by the first physical channel, the terminal can give priority to sending or receiving data within the time range corresponding to the first time domain resources based on the low priority of the first measurement configuration and / or the high priority of the first physical channel, thereby increasing the probability of the time slot or micro time slot where the first time domain resource is located being scheduled, and ensuring the transmission delay and reliability of delay-critical services.

[0152] The above method provided in the embodiment of the present application will be described in detail below with reference to Figures 8 to 10.

[0153] It should be understood that the signals between the various devices or apparatuses, the names of the parameters in the signals, or the names of the information carried by the signals in the following embodiments of the present application are only examples, and other names may also be used in specific implementations, and the embodiments of the present application do not specifically limit this. In the present application, the access network device and the terminal are used as examples to illustrate the execution subjects of the interaction diagram, but the present application does not limit the execution subjects of the interaction diagram. For example, the method executed by the access network device in the present application may also be implemented by a module in the access network device (such as a circuit, a chip or a chip system, etc.), or a logical node, a logical module or software that can realize all or part of the functions of the access network device; the method executed by the terminal in the present application may also be implemented by a communication module in the terminal or a circuit or chip in the terminal responsible for the communication function (such as a modem chip (also known as a baseband chip), or a SoC chip containing a modem core, or a SIP chip).

[0154] In this application, performing / executing measurement can be understood as the terminal performing measurement, or it can be understood as the communication module of the terminal or the circuit or chip responsible for the communication function in the terminal (such as a modem chip, or a SoC chip containing a modem core, or a SIP chip) performing measurement-related operations.

[0155] In this application, skipping / stopping measurement can be understood as the terminal not performing measurement, or it can be understood as the terminal's communication module or the circuit or chip responsible for communication functions in the terminal (such as a modem chip, or a SoC chip containing a modem core, or a SIP chip) not performing measurement-related operations. At this time, the terminal or the unit, module, or chip inside the terminal can perform other operations such as data transmission or channel measurement.

[0156] FIG8 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG8 , the communication method includes the following steps:

[0157] S801. A terminal obtains a first measurement configuration, where the first measurement configuration is used to indicate a measurement time window, where the measurement time window includes a first time domain resource and a second time domain resource.

[0158] S802. The terminal performs data sending or receiving processing within a time range corresponding to the second time domain resource.

[0159] S803: When the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, the terminal performs data transmission or reception within a time range corresponding to a first time domain resource, where the first time domain resource overlaps with a time domain resource of the first physical channel, or the first time domain resource overlaps with a time domain resource corresponding to a DRX timer triggered by the first physical channel.

[0160] It should be understood that in the embodiment of the present application, step S802 and step S803 can be executed simultaneously, or step S802 can be executed first, or step S803 can be executed first, depending on the time sequence of the first time domain resource and the second time domain resource. The embodiment of the present application does not make specific limitations on this.

[0161] The following describes steps S801 to S803 in detail.

[0162] For step S801:

[0163] It can be understood that the first measurement configuration can be the SMTC in the aforementioned "measurement", and the measurement time window can be the SMTC window. For details, please refer to the relevant description about SMTC, which will not be repeated here.

[0164] In addition, the first measurement configuration may be received by the terminal from the access network device.

[0165] In a possible implementation, the method flow shown in FIG8 further includes:

[0166] S804: The access network device sends first configuration information to the terminal. Correspondingly, the terminal receives the first configuration information from the access network device. The first configuration information is used to indicate a measurement time window, and the measurement time window corresponds to the first measurement configuration.

[0167] In other words, the first measurement configuration is configured by the access network device to the terminal. For example, in the handover process of the terminal, the access network device (i.e., the source access network device) may send an RRC reconfiguration message to the terminal, and the RRC reconfiguration message may carry the first measurement configuration, which is used for the terminal to measure the SSB of the target cell. It is understandable that the access network device may also send the first measurement configuration to the terminal at other times besides the handover process, and may also use other messages besides the RRC reconfiguration message to carry the first measurement configuration, and the embodiments of the present application do not specifically limit this.

[0168] In addition, the access network device executing step S804 may be the access network device in FIG7 . Furthermore, the embodiment of the present application does not limit the execution of step S804 to the access network device itself, but may also be a module (such as a circuit, chip, or chip system) in the access network device, or a logical node, logical module, or software that can implement all or part of the functions of the access network device.

[0169] It can be understood that for the execution entity of step S801, which is the circuit or chip responsible for the communication function in the terminal (for example, a modem chip in the terminal), the terminal obtains the first measurement configuration, which may refer to the modem chip obtaining the first measurement configuration from other logic modules in the terminal (for example, a radio frequency (RF) processing system); or, the modem chip obtains the first measurement configuration from a memory in the terminal. This embodiment of the present application does not specifically limit this.

[0170] In addition, the logic module responsible for the upper layer protocol stack within the terminal may receive a service data unit (SDU) carrying the first measurement configuration and delivered by the logic module responsible for the lower layer protocol stack within the terminal. For example, the RRC layer may receive the SDU carrying the first measurement configuration and delivered by the PDCP layer, thereby obtaining the first measurement configuration.

[0171] It should be understood that according to the relevant description in the "Scheduling Restrictions" in the preamble of the specific implementation method, the first time domain resources may include: the SSB symbol to be measured, and / or, L data symbols before each consecutive SSB symbol to be measured, and L data symbols after each consecutive SSB symbol to be measured, where L is an integer greater than or equal to 1. In other words, the first time domain resources may include the time domain resources causing the scheduling restriction due to measurement, or the SSB symbol to be measured, or the L data symbols before the consecutive SSB symbols to be measured, and the L data symbols after the consecutive SSB symbols to be measured. Furthermore, at least part of the time domain resources with scheduling restrictions within the SMTC window may be flexibly relaxed based on service requirements to increase the probability of scheduling the time slot or micro-time slot where the symbol to be measured is located, thereby improving resource utilization and meeting requirements such as latency and reliability of service transmission.

[0172] It can be understood that according to the relevant instructions of the 3GPP protocol on scheduling restrictions, in the FR1 frequency band, L = 1. In addition, for the F2 frequency band, when the SCS used by SSB is 120kHz or 480kHz, the protocol stipulates that the high-level parameter deriveSSB-IndexFromCell is activated. For example, when the SCS used by the data symbols of the serving cell is 120kHz, L = 1; when the SCS used by the data symbols of the serving cell is 480kHz, and the SCS used by SSB is 120kHz or 480kHz, L = 4. When the SCS used by the data symbols of the serving cell is 480kHz and the SCS used by SSB is 960kHz, L = 3; when the SCS used by the data symbols of the serving cell is 960kHz, and the SCS used by SSB is 120kHz or 480kHz, L = 7; when the SCS used by the data symbols of the serving cell is 960kHz, and the SCS used by SSB is 960kHz, L = 4.

[0173] In addition, when the high-level parameter deriveSSB-IndexFromCell is not activated and the SCS used by SSB is 960kHz, if the SCS used by the data symbols of the serving cell is 120kHz, then L=2; if the SCS used by the data symbols of the serving cell is 480kHz, then L=4; if the SCS used by the data symbols of the serving cell is 960kHz, then L=7.

[0174] In addition, to further improve the flexibility of relaxing the scheduling restrictions on time domain resources within the SMTC window, the first time domain resources may be at least part of the time domain resources within the scheduling restrictions. For example, the first time domain resources may be part of the SSB symbols to be measured, so that part of the SSB symbols to be measured within the SMTC window can be used for service scheduling transmission, and the remaining SSB symbols to be measured can be used for measurement, etc. This embodiment of the present application does not specifically limit this.

[0175] It can be understood that the value of L is related to the SCS used by the data symbols of the serving cell and the SCS used by the SSB of the target cell (which can be configured to the terminal through the MeasObjectNR element), and the above-mentioned specific value of L is only an example. The value of L can be negotiated or indicated in advance between the terminal and the access network device, and the embodiments of the present application do not make specific limitations on this.

[0176] It should be understood that the second time domain resources in the embodiment of the present application may be at least part of the time domain resources other than the time domain resources subject to scheduling restrictions within the SMTC.

[0177] For ease of understanding, the following takes the measurement time window as the SMTC window as an example, and further illustrates the first time domain resource and the second time domain resource in conjunction with FIG5(a) and FIG5(c).

[0178] A. For the SSB symbol time domain position distribution shown in (a) of Figure 5:

[0179] Assuming the SMTC length is 2ms, as shown in (a) of Figure 9, the SMTC window is a time window that includes the entire subframe #0 and subframe #1. Combined with the relevant description of the scheduling restrictions for the FR1 frequency band in "Scheduling Restrictions", the time domain resources subject to scheduling restrictions include, in addition to the SSB symbol to be measured, one data symbol before each consecutive SSB symbol to be measured, and one data symbol after each consecutive SSB symbol to be measured. Therefore, the time domain resources subject to scheduling restrictions within the SMTC window are: symbols #1 to #12 within subframe #0, and symbols #1 to #12 within subframe #1. In other words, the second time domain resources may include one or more of: symbol #0 within subframe #0, symbol #13 within subframe #0, symbol #0 within subframe #1, or symbol #13 within subframe #1.

[0180] It can be understood that the first time domain resources may include: symbols #1 to #12 in subframe #0 and at least part of the time domain resources of symbols #1 to #12 in subframe #1. For example, the first time domain resources may include SSB symbols to be measured, namely symbols 2 to #5 in subframe #0, symbols #8 to #11 in subframe #0, symbols 2 to #5 in subframe #1, and symbols #8 to #11 in subframe #1. It can be understood that the first time domain resources may also include part of the SS symbols to be measured, such as symbols 2 to #5 in subframe #0. That is, in the scheduling-restricted time domain resources shown in (a) of Figure 9, except for symbols 2 to #5 in subframe #0, other SSB symbols to be measured can be used for measurement, thereby reducing the impact on terminal measurement to avoid untimely switching.

[0181] For another example, the first time domain resource may include one data symbol before each consecutive SSB symbol to be measured, and one data symbol after each consecutive SSB symbol to be measured, that is, symbol #1 and symbol #12 in subframe #0, and symbol #1 and symbol #12 in subframe #1. Alternatively, the first time domain resource may be at least part of the multiple data symbols subject to the above scheduling restrictions, that is, the first time domain resource may only include symbol #1 in subframe #0. It can be understood that, in conjunction with (b) in Figure 6, if the first time domain resource can be symbol #1 in subframe #0 in (b) in Figure 6, then symbol #1 can be scheduled to transmit service frame #6, thereby not affecting the transmission delay of delay-critical services, and subsequent SSB symbols to be measured in SMTC window # can also be used for measurement.

[0182] B. For the SSB symbol time domain position distribution shown in (c) of Figure (5):

[0183] Assuming the SMTC length is 1ms, as shown in (b) of Figure 9, the SMTC window is a time window that includes the complete subframe #0, where subframe #0 includes time slot #0 and time slot #1. In combination with the relevant description of scheduling restrictions for the FR1 frequency band in "Scheduling Restrictions", the time domain resources subject to scheduling restrictions within the SMTC window are: symbols #3 to #12 within time slot #0, and symbols #1 to #10 within time slot #1. In other words, the second time domain resources may include: symbols #0 to #2 within time slot #0, symbol #13 within time slot #0, symbol #0 within time slot #1, or one or more of symbols #11 to #13 within time slot #1.

[0184] It can be understood that, as described in (a) of the aforementioned Figure 9 regarding the first time domain resources, the first time domain resources in (b) of Figure 9 can be symbols #3 to #12 in time slot #0, and at least part of the resources in symbols #1 to #10 in time slot #1. For details, please refer to (a) of Figure 9 regarding the relevant description of the first time domain resources, which will not be repeated here.

[0185] In addition, the first time domain resources and the second time domain resources in (a) and (b) in the above Figure 9 are only examples. According to the time domain position distribution of different SSB symbols, or the value of L, the first time domain resources and the second time domain resources can also be other forms of time domain position distribution. The embodiments of the present application do not make specific limitations on this.

[0186] For step S802:

[0187] It can be understood that the terminal can perform data sending or receiving processing within the time range corresponding to the second time domain resource, for example, it can include: the terminal monitors the PDCCH within the time range corresponding to the second time domain resource. Among them, the terminal can use one or more of the following identifiers to monitor the downlink control information (DCI) carried by the PDCCH: cell radio network temporary identity (C-RNTI), configured scheduling RNTI (CS-RNTI), interruption RNTI (INT-RNTI), slot format indicator RNTI (SFI-RNTI), semi-persistent channel state information RNTI (SP-CSI-RNTI), etc. The embodiments of the present application do not make specific limitations on this.

[0188] It should be understood that the data sending or receiving in the embodiments of the present application may refer to data in the protocol layer above the PHY layer, or may refer to data within the PHY layer, and the embodiments of the present application do not specifically limit this.

[0189] For another example, the terminal may perform reception processing on the PDSCH within the time range corresponding to the second time domain resource. The reception processing may include, for example, reception processing at the PHY layer, reception processing at the MAC layer, reception processing at the RLC layer, reception processing at the PDCP layer, or reception processing at the SDAP layer, and this embodiment of the present application does not specifically limit this.

[0190] For another example, the terminal may perform transmission processing on the PUCCH within the time range corresponding to the second time domain resource. The transmission processing may include, for example, one or more of the transmission processing of the PHY layer, the transmission processing of the MAC layer, the transmission processing of the RLC layer, the transmission processing of the PDCP layer, or the transmission processing of the SDAP layer, which is not specifically limited in the embodiments of the present application.

[0191] For another example, the terminal may perform transmission processing on the PUSCH in the time range corresponding to the second time domain resource.

[0192] It can be understood that the data sending or receiving processing performed by the terminal in step S802 may correspond to the access network device.

[0193] In a possible implementation, the flowchart provided in FIG8 further includes:

[0194] S805: The access network device performs data sending or receiving processing within a time range corresponding to the second time domain resource.

[0195] It can be understood that step S805 corresponds to step S802. For example, the access network device performs PDCCH transmission processing within the range corresponding to the second time domain resource, and the terminal can monitor the PDCCH within the time range corresponding to the second time domain resource. For another example, the access network device performs transmission processing on the PDSCH within the time range corresponding to the second time domain resource, and the terminal performs reception processing on the PDSCH within the time range corresponding to the second time domain resource. For another example, the terminal device performs transmission processing on the PUCCH within the time range corresponding to the second time domain resource, and the access network device performs reception processing on the PUCCH within the time range corresponding to the second time domain resource. For another example, the terminal performs transmission processing on the PUSCH within the time range corresponding to the second time domain resource, and the access network device performs reception processing on the PUSCH within the time range corresponding to the second time domain resource UI.

[0196] In addition, if the terminal has a radio frequency processing system and the access network device has a device processing system, the access network device may send data to the terminal within the time range corresponding to the second time domain resource. Accordingly, the terminal receives data from the access network device within the time range corresponding to the second time domain resource. Alternatively, the terminal may send data to the access network device within the time range corresponding to the second time domain resource. Accordingly, the access network device receives data from the terminal within the time range corresponding to the second time domain resource.

[0197] For step S803:

[0198] It can be understood that the action of the terminal performing data sending or receiving processing in step S803 may correspond to the access network device.

[0199] In a possible implementation, the flowchart provided in FIG8 further includes:

[0200] S806. When the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, the access network device performs data sending or receiving within the time range corresponding to the first time domain resource, and the first time domain resource overlaps with the time domain resource of the first physical channel, or the first time domain resource overlaps with the time domain resource corresponding to the discontinuous reception DRX timer triggered by the first physical channel.

[0201] It can be understood that the action of the terminal sending or processing data in step S803 and the action of the access network device sending or processing data in step S806 can be specifically referred to steps S802 and S805, and will not be repeated here.

[0202] In addition, the data sent or received in step S802 and the data sent or received in step S803 may belong to the same TB or different TBs, or may belong to the same code block (CB) or different CBs of the same TB, or may correspond to the same redundancy version (RV) or different RVs of the same TB. This embodiment of the present application does not specifically limit this.

[0203] It can be understood that in steps S803 and S806, based on the different time domain resources associated with the first physical channel, the process can be divided into case A and case B for explanation respectively.

[0204] Case A: the first time domain resource overlaps with the time domain resource of the first physical channel.

[0205] It should be understood that the time domain resources of the first physical channel may be the time domain resources of the first physical channel dynamically scheduled by the access network device; or, the time domain resources of the first physical channel may be the uplink time domain resources pre-configured by the access network device for the terminal, such as the time domain resources included in the pre-configured uplink resources (PUR) and the time domain resources included in the CG resources (such as Type 1CG).

[0206] It is understood that the first physical channel may be a PDCCH, or a dynamically scheduled PDSCH or PUCCH or PDSCH. In addition, the first physical information may be a dynamically scheduled PUCCH or PUSCH, or a pre-configured PUSCH, which is not specifically limited in the embodiments of the present application.

[0207] It can be understood that the first time domain resources overlap with the time domain resources of the first physical channel, which may include: the time domain resources of the first physical channel include the first time domain resources, or the first time domain resources include the time domain resources of the first physical channel, or the first time domain resources partially overlap with the time domain resources of the first physical channel.

[0208] For example, referring to Figure 6 , assume that service frame #4 in Figure 6 is carried by the first physical channel, and the time domain resources of the first physical channel include the first time domain resources in SMTC window #2. Furthermore, service frame #6 in Figure 6 is carried by the first physical channel, and thus the time domain resource that overlaps between the time domain resources of the first physical channel and the first time domain resources in SMTC window #3 (e.g., symbols #1 to #11 in subframe #0) is symbol #1 in subframe #0.

[0209] It can be understood that for some service data with a smaller amount of data, the time domain resources of the first physical channel carrying the service data may be 2 symbols, and thus the first time domain resources may include the time domain resources of the first physical channel.

[0210] In addition, the above overlap between the first time domain resource and the time domain resource of the first physical channel is only an example. The first time domain resource may also overlap with the time domain of the first physical channel, and the embodiments of the present application do not specifically limit this.

[0211] The following respectively illustrates that the priority of the first measurement configuration is low, and the priority of the first physical channel is high.

[0212] For the first measurement configuration the priority is low:

[0213] In one possible implementation, the priority of the first measurement configuration is low, specifically: the priority of the first measurement configuration is lower than that of data transmission, or the priority of the first measurement configuration is a first value, or the priority of the first measurement configuration is lower than a first threshold. In other words, by setting a priority for the first measurement configuration to indicate that the priority of the first measurement configuration is low, the terminal can determine that the priority of measuring on the first time domain resource within the measurement time window indicated by the first measurement configuration is low, so that the terminal determines that data can be sent or received on the first time domain resource, thereby improving the resource utilization of the time slot or micro-time slot where the first time domain resource is located, and meeting the transmission delay requirement of delay-critical services.

[0214] For example, if the priority of the first measurement configuration is lower than that of data transmission, a first priority parameter (such as smtcPriorityOverData) can be set for the first measurement configuration. When the first priority parameter is configured to the second value, it can indicate that measuring the SSB symbol within the measurement time window is a low priority, or that data is sent or received first within the measurement time window. The second value may be "low" or other specific values ​​(or symbols). The other specific values ​​may be agreed upon by the protocol, negotiated in advance between the terminal and the access network device, or indicated by the access network device. This embodiment of the present application is not limited to this.

[0215] It can be understood that when the first priority parameter is configured as "high" or other specific values ​​different from the above-mentioned second value, it can indicate that measuring the SSB symbol within the measurement time window is a high priority, or that the SSB symbol is measured first within the measurement time window.

[0216] For another example, for the first measurement configuration whose priority is the first value, a second priority parameter (such as smtcPriority) can be set for the first measurement configuration. When the second priority parameter is configured as the first value, it can indicate that measuring the SSB symbol within the measurement time window is a low priority, or that data is sent or received preferentially within the measurement time window. The first value can be value 1 (value1) or other specific values ​​(or symbols), which is not limited in this embodiment of the present application.

[0217] It can be understood that when the second priority parameter is configured as value 2 (value2) or other specific values ​​different from the above-mentioned first value, it can indicate that measuring SSB symbols within the measurement time window is a high priority, or that SSB symbols are measured preferentially within the measurement time window.

[0218] For another example, if the priority of the first measurement configuration is lower than the first threshold, a priority threshold (e.g., smtcPriorityThreshold) can be set for the first measurement configuration based on the second priority parameter, that is, the first threshold, and then when the value of the second priority parameter is lower than the first threshold, it indicates that measuring the SSB symbol within the measurement time window is a low priority, or that data is sent or received with priority within the measurement time window. When the value of the second priority parameter is higher than or equal to the first threshold, it indicates that measuring the SSB symbol within the measurement time window is a high priority, or that the SSB symbol is measured with priority within the measurement time window.

[0219] In addition, for the case where the priority of the first measurement configuration is lower than the first threshold, another possible implementation is: the priority of the first measurement configuration is lower than or equal to the first threshold, and then when the value of the second priority parameter is lower than or equal to the first threshold, it indicates that measuring the SSB symbol within the measurement time window is a low priority, or that data is sent or received preferentially within the measurement time window. When the value of the second priority parameter is higher than the first threshold, it indicates that measuring the SSB symbol within the measurement time window is a high priority, or that the SSB symbol is measured preferentially within the measurement time window.

[0220] It can be understood that the value of the first threshold may be agreed upon by the protocol, or negotiated in advance between the terminal and the access network device, or indicated by the access network device, and the embodiments of the present application do not specifically limit this.

[0221] It should be understood that the access network device can configure different first measurement configurations for the terminal, and the second priority parameters of different first measurement configurations can be different. Furthermore, by configuring the first threshold value for the terminal by the access network device, the first measurement device with a second priority parameter lower than or equal to the first threshold value in multiple first measurement configurations can be configured as a first measurement configuration that can preferentially transmit data, thereby enabling the first measurement configuration desired by the access network device to preferentially transmit data. For example, the first threshold value configured by the access network device for the terminal is 2, and then, among the multiple second priority parameters corresponding to the multiple first measurement configurations, the first measurement configuration with a second priority parameter higher than 2 has a higher priority, and the first measurement configuration with a second priority parameter lower than 2 has a lower priority.

[0222] In addition, the above first priority parameter or second priority parameter can be included in the first measurement configuration, or can be carried in the same message as the first measurement configuration, or can be sent separately from the first measurement configuration. This embodiment of the present application does not specifically limit this.

[0223] It can be understood that the first threshold can be configured by the access network device to the terminal through RRC signaling, or the access network device can indicate it to the terminal through a DCI or MAC control element (CE), and the embodiments of the present application do not specifically limit this.

[0224] For the first physical channel, the priority is high:

[0225] In one possible implementation, the priority of the first physical channel is high, specifically: the priority of the first physical channel is the second value, or the priority of the logical channel with the highest priority corresponding to the first physical channel is higher than the second threshold, or the priority of the MAC CE with the highest priority corresponding to the first physical channel is higher than the third threshold. In other words, the terminal can determine that the priority of the first physical channel is high based on the priority of the first physical channel, or the priority of the logical channel with the highest priority corresponding to the first physical channel is higher than the second threshold, or the priority of the MAC CE with the highest priority corresponding to the first physical channel is higher than the third threshold. Thus, the terminal does not change the method for determining the priority of the first physical channel, makes little change to the protocol, and is easy to deploy.

[0226] For example, when the priority of the first physical channel is the second value, the priority of the first physical channel may refer to the priority index of the first physical channel. The protocol stipulates that a priority index of 1 indicates a high priority, and a priority index of 0 indicates a low priority.

[0227] For another example, the priority of the highest-priority logical channel corresponding to the first physical channel is higher than the second threshold value, and the priority corresponding to the first physical channel refers to the priority of the logical channel mapped to the MAC protocol data unit (PDU) corresponding to the transport block (TB) carried by the first physical channel, or the priority of the highest-priority logical channel in the logical channel group mapped to the MAC PDU corresponding to the TB carried by the first physical channel. In addition, the second threshold value may refer to the threshold value indicated by the configured high-level parameter uplink priority threshold (ul-PrioritizationThres).

[0228] It can be understood that if the priority of the logical channel with the highest priority corresponding to the first physical channel is lower than or equal to the second threshold, the priority of the first physical channel is low.

[0229] It should be understood that the priority of the highest-priority logical channel corresponding to the above-mentioned first physical channel is higher than the second threshold. Another possible implementation is: the priority of the highest-priority logical channel corresponding to the first physical channel is higher than or equal to the second threshold, that is, if the priority of the highest-priority logical channel corresponding to the first physical channel is higher than or equal to the second threshold, then the priority of the first physical channel is high; if the priority of the highest-priority logical channel corresponding to the first physical channel is lower than the second threshold, then the priority of the first physical channel is low.

[0230] For another example, the priority of the highest-priority MAC CE corresponding to the first physical channel is higher than the third threshold value. The priority corresponding to the first physical channel refers to the priority of the MAC CE included in the MAC PDU corresponding to the transport block (TB) carried by the first physical channel, or the priority of the MAC CE with the highest priority among multiple MAC CEs included in the MAC PDU corresponding to the TB carried by the first physical channel. In addition, the third threshold value may refer to the threshold value indicated by the high-level parameter ul-PrioritizationThres.

[0231] It can be understood that if the priority of the MAC CE with the highest priority corresponding to the first physical channel is lower than or equal to the third threshold, the priority of the first physical channel is low.

[0232] It should be understood that for the above-mentioned first physical channel, the priority of the highest-priority MAC CE corresponding to the highest priority is higher than the third threshold. Another possible implementation is: the priority of the highest-priority MAC CE corresponding to the first physical channel is higher than or equal to the third threshold, that is, if the priority of the highest-priority MAC CE corresponding to the first physical channel is higher than or equal to the third threshold, the priority of the first physical channel is high; if the priority of the highest-priority MAC CE corresponding to the first physical channel is lower than the third threshold, the priority of the first physical channel is low.

[0233] It should be understood that when the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, the terminal performs data sending or receiving within the time range corresponding to the first time domain resource. Another possible implementation is: when the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, the terminal skips / stops SSB measurement.

[0234] In addition, the terminal skipping / stopping the measurement of SSB may mean: the terminal stops measuring the SSB at the SSB symbol to be measured within the measurement time window; or, the terminal stops measuring the SSB at the time domain starting position of the measurement time window; or, the terminal stops measuring the SSB at any SSB symbol within the measurement time window; or, the terminal stops measuring the SSB at any time domain position within the measurement time window. The embodiments of the present application do not make specific limitations on this.

[0235] It should be understood that the duration for which the terminal stops SSB measurement may be agreed upon by the protocol, or reported by the terminal, or indicated by the access network device, or negotiated in advance between the terminal and the access network device. The embodiments of the present application do not specifically limit this.

[0236] Case B: the first time domain resource overlaps with the time domain resource corresponding to the DRX timer triggered by the first physical channel.

[0237] It can be understood that the first physical channel triggering the DRX timer in the embodiment of the present application refers to the terminal receiving or sending the first physical channel, and then the terminal starts (starts) or restarts (restarts) the DRX timer. This is explained uniformly here and will not be repeated below.

[0238] In addition, in the DRX scenario, the start or restart of some DRX timers means that the terminal will receive downlink data or receive scheduling information to send uplink data in the next period of time. If data cannot be received or sent during this period due to the measured scheduling restrictions, the transmission performance of the service will be affected.

[0239] It can be understood that the time domain resource corresponding to the DRX timer triggered by the first physical channel is defined by the start or restart time of the DRX timer and the duration of the DRX timer, which is explained below based on different types of DRX timers.

[0240] Case 1: The DRX timer is a DRX inactive timer:

[0241] It is understood that the DRX inactivity timer is triggered by the PDCCH used to schedule new transmission data, and thus the first physical channel can be the PDCCH used to schedule new transmission of PUSCH or PDSCH. In addition, the DRX inactivity timer is started or restarted at the first symbol after the terminal successfully decodes the PDCCH. The duration of the DRX inactivity timer may include: the timeout duration of the DRX inactivity timer, or the duration from the start or restart of the DRX inactivity timer to the receipt of a DRX command MAC CE (DRX command MAC CE) from the access network device.

[0242] It should be understood that the duration of the DRX inactivity timer is the timeout duration of the DRX inactivity timer, and the first time domain resource overlaps with the time domain resource corresponding to the DRX inactivity timer. For details, please refer to the overlap of the first time domain resource and the time domain resource of the first physical channel in situation A, that is, the first time domain resource and the time domain resource corresponding to the DRX inactivity timer can have an inclusion relationship, a being included relationship, partial overlap, or coincidence, etc., and the details will not be repeated here.

[0243] The duration of the DRX inactivity timer is: the duration from the start or restart of the DRX inactivity timer to the reception of the DRX command MAC CE (DRX command MAC CE) from the access network device by the terminal, which is explained in conjunction with FIG10 .

[0244] Figure 10 is a schematic diagram illustrating an overlap between a first time domain resource and a time domain resource corresponding to a DRX inactivity timer, provided in an embodiment of the present application. As shown in Figure 10 , the time domain starting position of the first time domain resource should be after the DRX inactivity timer is started or restarted. Furthermore, after the DRX inactivity timer is started or restarted, the terminal begins monitoring the PDCCH. If the time domain starting position of the first time domain resource is before the terminal receives a DRX command MAC CE, the terminal determines that the first time domain resource overlaps with the time domain resource corresponding to the DRX inactivity timer.

[0245] It can be understood that, as shown in FIG10 , the time domain resources corresponding to the DRX inactivity timer may include the first time domain resources, or the two may partially overlap.

[0246] In one possible implementation, the first physical channel is used to schedule new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX inactivity timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX inactivity timer is defined by the duration of the DRX inactivity timer; data sending or receiving processing is performed within the time range corresponding to the first time domain resource (step S803), including: the terminal listens to the second physical channel used for scheduling new transmission of data within the time range corresponding to the first time domain resource.

[0247] That is to say, when the priority of the first physical channel that triggers the start or restart of the DRX inactivity timer is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel for new transmission of scheduling data within the first time domain resource, thereby increasing the probability of the time slot or micro time slot where the first time domain resource is located being scheduled.

[0248] For example, as shown in Figure 10, the first time domain resource is included in the time domain resource corresponding to the DRX inactivity timer. Since the first time domain resource is schedulable, the access network device can schedule the time slot or micro time slot where the first time domain resource is located for the terminal to send PUSCH or receive PDSCH.

[0249] Case 2: The DRX timer is the DRX retransmission downlink timer:

[0250] It can be understood that after the terminal receives the newly transmitted PDCCH or SPS PDSCH for scheduling data, if the terminal fails to decode the PDSCH or SPS PDSCH scheduled by the PDCCH, it will start the drx-HARQ-RTT-TimerDL and start or restart the DRX retransmission downlink timer at the first symbol after the drx-HARQ-RTT-TimerDL times out.

[0251] It should be understood that the duration of the DRX downlink retransmission timer may include: the timeout duration of the DRX downlink retransmission timer, or the duration from the start or restart of the DRX downlink retransmission timer to the reception of the PDCCH for scheduling the retransmission of the data.

[0252] It can be understood that the duration of the DRX retransmission downlink timer is the timeout duration of the DRX retransmission downlink timer, and the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission downlink timer. For details, please refer to the overlap of the first time domain resource and the time domain resource of the first physical channel in situation A, that is, the first time domain resource and the time domain resource corresponding to the DRX retransmission downlink timer can have an inclusion relationship, a being included relationship, partial overlap, or coincidence, etc., and the details will not be repeated here.

[0253] The duration of the DRX downlink retransmission timer is: the duration from the start or restart of the DRX downlink retransmission timer to the receipt of the PDCCH for scheduling retransmission of the data by the terminal, which is similar to Figure 10 in Case 1, that is, the time domain starting position of the first time domain resource is after the start or restart of the DRX downlink retransmission timer. In addition, after the DRX downlink retransmission timer is started or restarted, the terminal begins to monitor the PDCCH. If the time domain starting position of the first time domain resource is before the terminal receives the PDCCH for scheduling retransmission of the data, the terminal determines that the first time domain resource overlaps with the time domain resource corresponding to the DRX downlink retransmission timer.

[0254] It can be understood that the time domain resources corresponding to the DRX downlink retransmission timer may include the first time domain resources, or the two may partially overlap.

[0255] In one possible implementation, the first physical channel is used to schedule new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission downlink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission downlink timer is defined by the duration of the DRX retransmission downlink timer; data sending or receiving processing is performed within the time range corresponding to the first time domain resource (step S803), including: the terminal monitors the second physical channel used to schedule retransmission of the data within the time range corresponding to the first time domain resource.

[0256] That is to say, when the first physical channel is a PDCCH for scheduling new transmission of downlink data, and triggers the start or restart of the DRX retransmission downlink timer, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel for scheduling retransmission of the downlink data within the first time domain resource, and then can give priority to ensuring the retransmission of the downlink data, thereby improving the reliability of service transmission.

[0257] It can be understood that the first physical channel may be a PDCCH for scheduling new transmission data, and the second physical channel may be a PDCCH for scheduling retransmission of the data.

[0258] In one possible implementation, the first physical channel is used to carry new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission downlink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission downlink timer is defined by the duration of the DRX retransmission downlink timer; data sending or receiving processing is performed within the time range corresponding to the first time domain resource (step S803), including: the terminal monitors the second physical channel used to schedule data retransmission within the time range corresponding to the first time domain resource.

[0259] That is to say, when the first physical channel is a newly transmitted PDSCH for carrying downlink data, and the DRX retransmission downlink timer is triggered to start or restart, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel for scheduling the retransmission of the downlink data within the first time domain resource, thereby avoiding prioritizing the retransmission of the downlink data, thereby improving the reliability of service transmission.

[0260] It can be understood that the first physical channel may be an SPS PDSCH that carries newly transmitted data, and the second physical channel may be a PDCCH that schedules retransmission of the data.

[0261] Case 3: The DRX timer is the DRX retransmission uplink timer:

[0262] It can be understood that after the terminal sends the PUSCH, the terminal starts the drx-HARQ-RTT-TimerUL for the HARQ process corresponding to the PUSCH, and starts or restarts the DRX retransmission uplink timer at the first symbol after the DRX-HARQ round trip uplink timer expires.

[0263] It should be understood that the duration of the DRX retransmission uplink timer may include: the timeout duration of the DRX retransmission uplink timer, or the duration from the start or restart of the DRX retransmission uplink timer to the reception of the PDCCH for scheduling the retransmission of the data.

[0264] It can be understood that the duration of the DRX retransmission uplink timer is the timeout duration of the DRX retransmission uplink timer, and the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission uplink timer. For details, please refer to the overlap of the first time domain resource and the time domain resource of the first physical channel in situation A, that is, the first time domain resource and the time domain resource corresponding to the DRX retransmission uplink timer can have an inclusion relationship, a being included relationship, partial overlap, or coincidence, etc., and the details will not be repeated here.

[0265] The duration of the DRX retransmission uplink timer is: the duration from the start or restart of the DRX retransmission uplink timer to the receipt of the PDCCH for scheduling the retransmission of the data by the terminal, which is similar to Figure 10 in Case 1, that is, the time domain starting position of the first time domain resource is after the start or restart of the DRX retransmission uplink timer. In addition, after the DRX retransmission uplink timer is started or restarted, the terminal begins to monitor the PDCCH. If the time domain starting position of the first time domain resource is before the terminal receives the PDCCH for scheduling the retransmission of the data, the terminal determines that the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission uplink timer.

[0266] It can be understood that the time domain resources corresponding to the DRX retransmission uplink timer may include the first time domain resources, or the two may partially overlap.

[0267] In one possible implementation, the first physical channel is used to schedule new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission uplink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission uplink timer is defined by the duration of the DRX retransmission uplink timer; data sending or receiving processing is performed within the time range corresponding to the first time domain resource (step S803), including: the terminal monitors the second physical channel used for scheduling data retransmission within the time range corresponding to the first time domain resource.

[0268] That is to say, when the first physical channel is a PDCCH for scheduling new transmission of uplink data, and triggers the start or restart of the DRX retransmission uplink timer, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel for scheduling retransmission of the uplink data within the first time domain resource, and then can preferentially ensure the retransmission of the uplink data, thereby improving the reliability of service transmission.

[0269] In one possible implementation, the first physical channel is used to carry new transmission of data, the first time domain resource overlaps with the time domain resource corresponding to the DRX retransmission uplink timer triggered by the first physical channel, and the duration of the time domain resource corresponding to the DRX retransmission uplink timer is defined by the duration of the DRX retransmission uplink timer; data sending or receiving processing is performed within the time range corresponding to the first time domain resource (step S803), including: the terminal monitors the second physical channel used to schedule data retransmission within the time range corresponding to the first time domain resource.

[0270] That is to say, when the first physical channel is a newly transmitted PUSCH for carrying uplink data, and the DRX retransmission uplink timer is triggered to start or restart, and the priority of the first physical channel is high, and / or the priority of the first measurement configuration is low, the terminal can monitor the second physical channel for scheduling the retransmission of the uplink data within the first time domain resource, and thus can ensure the retransmission of the uplink data, thereby improving the reliability of service transmission.

[0271] It can be understood that the first measurement configuration in the above case B has a low priority. For details, please refer to the relevant description in case A, which will not be repeated here.

[0272] The high priority of the first physical channel in case B is similar to the method of determining the high priority of the first physical channel in case A, except that: when the first physical channel is SPS PDSCH, the first physical channel priority is indicated according to the HARQ codebook identifier (harq-CodebookID) field.

[0273] It is understood that for non-latency-critical services, the terminal may configure the first measurement to have a high priority and / or the first physical channel to have a low priority, and perform intra-frequency measurement or inter-frequency measurement within the time range corresponding to the first time domain resource. This is not specifically limited in the embodiments of the present application. In other words, when the service does not have a high transmission delay requirement, measurement can be prioritized to ensure the terminal's measurement performance, thereby enabling the terminal to perform handover in a timely manner.

[0274] It should be understood that the method flow shown in Figure 8 above is illustrated using SSB measurement as an example. The above method flow is also applicable to CSI-RS measurement, and the embodiments of the present application do not specifically limit this.

[0275] In addition, the access network device in steps S804 to S806 in the embodiment of the present application may include a CU, a DU, a CU-CP, a CU-UP, or an RU. The access network device may also include an AAU. The CU implements some functions of the access network device, and the DU implements some functions of the access network device. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the RRC and / or PDCP layers. The DU is responsible for processing PHY layer protocols and real-time services, and implementing the functions of the RLC layer, MAC layer, and PHY layer. The AAU implements some physical layer processing functions, radio frequency processing, and related functions of active antennas. Since the information at the RRC layer will eventually become information at the PHY layer, or be converted from information at the PHY layer, under this architecture, high-layer signaling, such as RRC signaling, can also be considered to be sent by the DU, or by the DU+AAU. It can be understood that the access network device can be a device including one or more of a CU node, a DU node, and an AAU node.

[0276] For example, the access network device may be the O-CU, O-DU, or O-RU in the aforementioned ORAN, or a combination of O-CU, O-DU, or O-RU. For example, the O-DU may perform data transmission or reception processing within the time range corresponding to the first time domain resource based on the low priority of the first measurement configuration and / or the high priority of the first physical channel. In addition, the near real-time or non-real-time radio intelligent controller (RIC) in the O-CU or ORAN architecture may also perform data transmission or reception processing within the time range corresponding to the first time domain resource based on the low priority of the first measurement configuration and / or the high priority of the first physical channel. The embodiments of the present application do not specifically limit this.

[0277] Because in an embodiment of the present application, when the first time domain resources with scheduling restrictions included in the measurement time window overlap with the time domain resources of the first physical channel or the time domain resources corresponding to the DRX timer triggered by the first physical channel, the terminal can give priority to sending or receiving data within the time range corresponding to the first time domain resources based on the low priority of the first measurement configuration and / or the high priority of the first physical channel, thereby increasing the probability of the time slot or micro time slot where the first time domain resource is located being scheduled, and ensuring the transmission delay and reliability of delay-critical services.

[0278] The above describes the method embodiments provided in the embodiments of the present application. Accordingly, the embodiments of the present application also provide a communication device, which is used to implement the various methods described above. The communication device can be the terminal in the above method embodiments, or a device including the above terminal, or a component that can be used for the terminal; alternatively, the communication device can be the access network device in the above method embodiments, or a device including the above access network device, or a component that can be used for the access network device.

[0279] Figure 11 is a schematic diagram of the structure of a communication device provided in an embodiment of the present application. As shown in Figure 11, communication device 1100 may include modules or units corresponding to the above method embodiments. In one possible design, communication device 1100 includes: a processing unit 1102. Optionally, communication device 1100 may also include a communication unit 1103. Optionally, communication device 1100 may also include a storage unit 1101 for storing device program code and / or data.

[0280] The communication device 1100 may be the terminal or a module in the terminal in the above embodiment. For example, the module in the terminal may be the terminal or a communication module in the terminal, or a circuit or chip in the terminal responsible for the communication function.

[0281] For example, in one embodiment, the processing unit 1102 is configured to: obtain a first measurement configuration, the first measurement configuration being configured to indicate a measurement time window, the measurement time window including a first time domain resource and a second time domain resource. The processing unit 1102 is further configured to perform data transmission or reception processing within a time range corresponding to the second time domain resource; and, when the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, perform data transmission or reception processing within a time range corresponding to the first time domain resource, the first time domain resource overlapping with a time domain resource of the first physical channel, or the first time domain resource overlapping with a time domain resource corresponding to a DRX timer triggered by the first physical channel.

[0282] In one possible design, when the communication device 1100 is a terminal or a communication module within a terminal, the functions of the processing unit 1102 may be implemented by one or more processors. Specifically, the processors may include a modem chip, or a system-on-chip (SoC) chip or SIP chip containing a modem core. The functions of the communication unit 1103 may be implemented by a transceiver circuit.

[0283] In one possible design, when the communication device 1100 is a circuit or chip responsible for communication functions in a terminal, such as a modem chip or a system-on-chip (SoC) chip or SIP chip containing a modem core, the functions of the processing unit 1102 can be implemented by a circuit system including one or more processors or processor cores in the aforementioned chip. The functions of the communication unit 1103 can be implemented by an interface circuit or data transceiver circuit on the aforementioned chip.

[0284] The communication device 1100 can be the access network device or a module within the access network device in the above embodiments. For example, the module within the access network device can be the access network device or a communication module in the access network device, or a circuit or chip responsible for the communication function in the access network device.

[0285] For example, in one embodiment, the communication unit 1103 is configured to send first configuration information indicating a measurement time window, where the measurement time window includes a first time domain resource and a second time domain resource. The processing unit 1102 is configured to: perform data transmission or reception processing within a time range corresponding to the second time domain resource; and, when the priority of the first measurement configuration is low and / or the priority of the first physical channel is high, perform data transmission or reception processing within a time range corresponding to the first time domain resource, where the first time domain resource overlaps with a time domain resource of the first physical channel, or overlaps with a time domain resource corresponding to a DRX timer triggered by the first physical channel.

[0286] It is understandable that the division of units in the above-mentioned device is merely a division of logical functions, and one function may correspond to one functional unit, or two or more functions may be integrated into one functional unit. In actual implementation, all or part of the units may be integrated into one physical entity, or distributed across different physical entities. In addition, the above-mentioned functional units may be implemented in the form of hardware, software, or a combination of hardware and software. Whether a function is executed in hardware or software depends on the specific application and design constraints of the technical solution. Professional and technical personnel may use different methods to implement the described functions for specific applications, but such implementation should not be considered to be beyond the scope of this application.

[0287] In one example, the functional unit in any of the above devices can be one or more integrated circuits configured to implement the above method, such as: one or more application specific integrated circuits (ASICs), or, one or more central processing units (CPUs), one or more microcontroller units (MCUs), one or more digital signal processors (DSPs), or, one or more field programmable gate arrays (FPGAs), or a combination of at least two of these integrated circuit forms.

[0288] In an example, the storage unit 1101 may include a random access memory, a flash memory, a read-only memory, a programmable read-only memory, or an electrically erasable programmable memory and / or a register.

[0289] In addition, the communication device 1100 can execute the above-mentioned communication method, so the technical effects that can be obtained can refer to the above-mentioned method embodiments and will not be repeated here.

[0290] Figure 12 is a schematic diagram of a terminal structure provided in an embodiment of the present application. This terminal may correspond to the terminal shown in Figure 7 and is used to implement the terminal operations in the above embodiments. As shown in Figure 12, the terminal includes: one or more antennas 1210, a radio frequency (RF) processing system 1220, and a processor system 1230.

[0291] In the downlink or sidelink direction, the RF processing system 1220 receives RF signals through the antenna 1210 and sends the processed signals to the processor system 1230 for further processing. In the uplink or sidelink direction, the processor system 1230 processes the terminal side information (such as data) and sends it to the RF processing system 1220. The RF processing system 1220 performs RF processing on the signal and then sends it through the antenna 1210.

[0292] In one example, the RF processing system 1220 serves as the communication interface for the terminal to communicate externally and may include an RF front end 1221 (RF front end, RFFE) and an RF transceiver 1222 (RF transceiver). RFFE 1221 is primarily used to perform one or more of the following processing operations on the RF signal received by the antenna or the RF signal to be transmitted through the antenna: shaping, passband selection, or gain. It may include one or more components such as an RF switch, a duplexer, a filter, a power amplifier, an antenna tuner, and a low-noise amplifier. RFFE 1221 may be a circuit system composed of multiple discrete devices or may be integrated and packaged in one or more chips. RF transceiver 1222 is used to process the RF signal received by the RFFE into a baseband / intermediate frequency (IF) signal for further processing by the processor system 1230, and to process the baseband / intermediate frequency (IF) signal provided by the processor system 1230 into an RF signal for transmission to RFFE 1221. The baseband / IF signal transmitted between RF transceiver 1222 and processor system 1230 may be a digital signal or an analog signal. The RF transceiver 1222 may be implemented by one or more chips, which are often referred to as radio frequency integrated circuits (RFICs).

[0293] In one example, the processor system 1230 may include one or more processors for processing signals and executing one or more communication protocols. Optionally, the processor system 1230 may also include a memory 1236. In one example, the one or more processors include at least one baseband processor 1231 (also known as a modem processor). The memory 1236 is used to store data and / or computer program instructions. Optionally, the processor system 1230 may also include one or more application processors 1232 for processing the terminal operating system and application layer. Optionally, the processor system 1230 may also include one or more of a voice subsystem 1233, a multimedia subsystem 1234, or an interface circuit 1235. The voice subsystem 1233 is used to process voice signals, the multimedia subsystem 1234 is used to handle multimedia-related operations such as video encoding and decoding, image processing, etc., and the interface circuit 1235 is used to communicate with other terminal components, such as the display 1240, input device 1250, and memory 1260. The aforementioned components in the processor system 1230 may communicate with each other via a bus or communication interface circuit.

[0294] In one example, the processor system 1230 can be packaged into a processor chip, such as a SoC chip or a SIP chip. In another example, the processor system 1230 can be a system consisting of multiple chips, for example, the baseband processor 1231 can be packaged into a single chip, or packaged into a single chip with part or all of the circuits of the radio frequency processing system.

[0295] In one example, the memory 1236 may be an on-chip memory, that is, located on the processor system 1230 chip. In one example, the memory 1260 may be an off-chip memory, that is, located outside the processor system 1230 chip.

[0296] In one example, the baseband processor 1231 may include one or more processor cores 12311 and an interface circuit 12314. The one or more processor cores 12311 are used to process signals and execute one or more communication protocols. Optionally, the baseband processor 1231 may also include a memory 12312, which is used to store at least part of the corresponding computer program instructions and / or data. In one example, the one or more processor cores 12311 implement the relevant operations in the above-mentioned method embodiment (data sending or receiving processing in the time range corresponding to the first time domain resource when the priority of the first measurement configuration is low and / or the priority of the first physical channel is high) by executing the computer program instructions stored in the memory 12312. In the embodiment of the present application, the memory 12312 is used to store corresponding computer program instructions and / or data.
