Description

Technical Field

[0001] The present invention relates to the field of wireless technology, and in particular to a physical downlink control channel (PDCCH) monitoring method, device, terminal and network side equipment. Background Art

[0002] With the changes in user needs and application scenarios of mobile communication systems, some services of the New Radio (NR) system have higher requirements for latency, such as Ultra-Reliable & Low Latency Communication (uRLLC) services and eXtend Reality (XR) services. For XR services, it can be understood as a broadband uRLLC service, or uRLLC + enhanced Mobile Broadband (eMMB) services, which not only require low latency and high reliability like uRLLC, but also require large bandwidth and high throughput like eMMB. Considering that XR devices such as handheld terminals and smart wearable devices that support XR, such as head-mounted XR devices or XR glasses, are battery-powered and limited in size, the power saving of XR devices is crucial to the widespread promotion of actual products.

[0003] In addition, for latency-sensitive low-latency services such as extended reality (XR) services (hereinafter referred to as low-latency services), in order to meet the KPIs of latency and reliability, a shorter frame structure is inevitably required. Therefore, the R15 standardized mini-slot based scheduling (also known as non-slotbased scheduling) is an essential solution to improve the latency performance of XR services.

[0004] Although mini-slot scheduling can effectively reduce latency, it will also greatly increase the density of downlink physical control channel monitoring opportunities (PDCCH Monitoring Occasion, PDCCH MO). Summary of the invention

[0127] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The mode indication method, terminal device, and network device provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0128] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1 As shown, it includes a user terminal 11 and a network side device 12, wherein the user terminal 11 may be a user equipment (User Equipment, UE), for example: it may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device) and other terminal side devices. It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned network side device 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0129] In order to clearly describe the PDCCH monitoring method according to the embodiment of the present invention, the PDCCH monitoring opportunity when the PDCCH is sent is first described below.

[0130] Usually, the transmission opportunity of the terminal to monitor PDCCH is jointly determined by the resource set CORESET and the search space (Search Space). In the Radio Resource Control (RRC) connection mode, the base station will configure the prior knowledge about PDCCH monitoring for each bandwidth part (BandWidth Part, BWP) of the terminal through dedicated RRC signaling, namely CORESET and its search space. The configuration information includes at least the frequency domain position of CORESET, the number of orthogonal frequency division multiplexing (OFDM) symbols occupied in the time domain, the aggregation level, position and downlink control information (DCI) format of PDCCH, etc. The terminal performs PDCCH blind detection operation on the corresponding PDCCH monitoring opportunity according to the DCI format configured by the high-level signaling.

[0131] In addition, the search space determines the absolute time position of PDCCH monitoring. The search space configures the PDCCH monitoring period in time slots, and the 14-bit bitmap indicates the start symbol of the PDCCH monitoring opportunity in the time slot. For example, the PDCCH monitoring period is one time slot, the resource set CORESET duration is 2 OFDM symbols, and the PDCCH monitoring pattern in the time slot is 01000010000100.

[0132] NR PDCCH is demodulated with a demodulation reference signal (DMRS). DMRS exists in each resource element group (REG) to which PDCCH is mapped, with a density of 1 / 4, that is, there are 3 DM-RSs in each REG. The initial value of DM-RS sequence scrambling is determined by configuring CORESET through RRC signaling, and each CORESET can independently configure the initial value of DM-RS sequence scrambling.

[0133] For delay-sensitive low-latency services such as XR services, micro-slot scheduling is used to improve the delay performance of the services. However, with micro-slot scheduling, the terminal must perform PDCCH blind detection in all PDCCH monitoring opportunities, and monitoring PDCCH will increase unnecessary terminal energy consumption. For example, micro-slot scheduling can have up to 7 PDCCH MOs in a time slot. According to the existing standard technical methods, the terminal must perform PDCCH blind detection in all its PDCCH MOs.

[0134] Since XR transmission supports large bandwidth and long transmission cycle, the terminal always monitors PDCCH in min-slot based PDCCH MO, which will greatly increase unnecessary terminal energy consumption. Based on this, in the current terminal energy-saving projects, in order to reduce terminal power consumption, corresponding technical solutions such as energy-saving signal triggered DRX adaptation and cross slot scheduling have been studied and standardized. However, these energy-saving technologies are mainly aimed at delay-insensitive services, exchanging delay for energy-saving gains. For delay-sensitive services, it is necessary to study terminal energy-saving solutions from a new dimension.

[0135] An embodiment of the present invention provides a PDCCH monitoring method, in which a network side device sends high-level configuration information to a terminal, so that during an activation period, the terminal receives monitoring indication information for indicating whether the terminal needs to perform PDCCH monitoring on a corresponding PDCCH monitoring opportunity, and performs PDCCH monitoring according to the monitoring indication information to support the reduction of PDCCH monitoring, thereby avoiding the need to perform PDCCH blind detection on all PDCCH monitoring opportunities, resulting in high terminal energy consumption, thereby solving the energy consumption problem of delay-sensitive services.

[0136] One embodiment of the present invention provides a PDCCH monitoring method, which is executed by a terminal, such as Figure 2 As shown, including:

[0137] S210, obtaining a signaling sent by a network side device;

[0138] S220, receiving monitoring indication information within the activation period according to the signaling; wherein the monitoring indication information is used to indicate whether the terminal needs to perform PDCCH monitoring on a corresponding PDCCH monitoring opportunity;

[0139] S230: Perform PDCCH monitoring according to the monitoring indication information.

[0140] In an embodiment of the present invention, optionally, the high-level configuration signaling is used to instruct the terminal to receive monitoring indication information during the activation period, so as to determine whether it is necessary to perform PDCCH monitoring on the PDCCH monitoring opportunity based on the monitoring indication information, thereby avoiding the need to perform PDCCH blind detection on all PDCCH monitoring opportunities and solving the energy consumption problem of delay-sensitive services.

[0141] Optionally, the signaling is high-layer configuration signaling.

[0142] Optionally, the PDCCH monitoring method, in step S230, performs PDCCH monitoring according to the monitoring indication information, including:

[0143] If the monitoring indication information is received, PDCCH monitoring is performed on the corresponding PDCCH monitoring opportunity;

[0144] If the monitoring indication information is not received, the monitoring of the PDCCH on the corresponding PDCCH monitoring opportunity is abandoned.

[0145] In this implementation manner, the monitoring indication information is information for triggering PDCCH monitoring on a corresponding PDCCH monitoring opportunity, and whether PDCCH monitoring needs to be performed on a corresponding PDCCH monitoring opportunity is determined based on whether the monitoring indication information is received.

[0146] In one implementation manner, optionally, the monitoring indication information is carried by an indication signal sent on a preset resource associated with a PDCCH monitoring opportunity.

[0147] In this implementation manner, the monitoring indication information is used to indicate whether it is necessary to perform PDCCH monitoring on the PDCCH monitoring opportunity associated with the preset resource.

[0148] In the PDCCH monitoring method described in the embodiment of the present invention, optionally, the high-level configuration signaling includes type indication information of PDCCH sending resources;

[0149] The step of receiving monitoring indication information during the activation period according to the high-level configuration signaling includes:

[0150] When it is determined that the PDCCH transmission resource is of the first type according to the type indication information, during the activation period, the indication signal carried is detected on the preset resources associated with the PDCCH monitoring opportunity of the PDCCH transmission resource of the first type to obtain the monitoring indication information.

[0151] In this implementation mode, the network side device can classify the PDCCH sending resources according to the terminal capabilities to distinguish whether PDCCH monitoring reduction is supported, so that the network side device sends an indication signal on the preset resources associated with the PDCCH monitoring opportunity, and the indication signal is used to carry the monitoring indication information to indicate whether the terminal needs to perform PDCCH monitoring on the PDCCH monitoring opportunity associated with the preset resources.

[0152] Optionally, in this embodiment, the method further includes:

[0153] If it is determined according to the type indication information that the PDCCH sending resource is of the second type, or the PDCCH sending resource is not of the first type, detection of the indication signal on the preset resource associated with the PDCCH listening opportunity is not performed, and PDCCH listening is performed directly according to the PDCCH listening opportunity.

[0154] Specifically, using this implementation, the PDCCH monitoring method, the first type of PDCCH transmission resources are reduced to support PDCCH monitoring. For the first type of PDCCH transmission resources, the network side device sends an indication signal on the preset resources associated with the PDCCH monitoring opportunity during the activation period of the terminal, and indicates whether the terminal needs to perform PDCCH monitoring through the monitoring indication information carried by the indication signal. For the second type of PDCCH transmission resources other than the first type, or the PDCCH transmission resources that are not configured as the first type, the network side device can maintain the normal PDCCH transmission behavior, that is, the terminal does not perform the detection of the indication signal on the preset resources associated with the PDCCH monitoring opportunity, and directly performs PDCCH monitoring according to the PDCCH monitoring opportunity.

[0155] In the PDCCH monitoring method described in the embodiment of the present invention, the high-level configuration signaling can indicate the type of PDCCH transmission resources configured by the terminal in an explicit manner or an implicit manner.

[0156] Optionally, in one embodiment, the type indication information is a configuration parameter defined in a high-level configuration signaling for indicating a resource type. Specifically, the configuration parameter defined in the high-level configuration signaling is used to indicate the resource type in an explicit manner. For example, for a resource set CORESET used to determine a PDCCH monitoring opportunity, a configuration parameter is added to the configuration of the CORESET to indicate the resource type of the PDCCH sending resource; for a search space used to determine a PDCCH monitoring opportunity, a configuration parameter is added to the configuration of the search space to indicate the resource type of the PDCCH sending resource.

[0157] Optionally, in another implementation manner, the type indication information indicates the first type by configuring an initial value parameter of a scrambling sequence of a demodulation reference signal DMRS as a preset designated value.

[0158] Specifically, the network side device and the terminal can agree on a dedicated DM-RS scrambling initial value DMRS-dedicated-value. When sending resource configuration to the terminal, the DM-RS scrambling sequence initial value parameter is configured as a preset specified value, such as PDCCH Monitoring Reduction-dedicated-value, to implicitly indicate that the corresponding PDCCH transmission resource is of the first type; optionally, the DM-RS scrambling sequence initial value parameter is configured as a regular value to indicate that the corresponding PDCCH transmission resource is of the second type, or other types other than the first type.

[0159] For example, when CORESET#n is configured to the terminal through high-level configuration signaling, the DM-RS scrambling sequence initial value parameter is configured as a preset specified value PDCCH Monitoring Reduction-dedicated-value to implicitly indicate that the sending resource type is the first type. Among them, the preset specified value PDCCH Monitoring Reduction-dedicated-value can be a newly added dedicated radio network temporary identifier (Radio Network Temporary Identifier, RNTI), and the RNTI value can be configured to the terminal when configuring the RNTI through high-level signaling.

[0160] In the PDCCH monitoring method described in the embodiment of the present invention, optionally, the indication signal carried on the preset resource includes at least one of the following:

[0161] A dedicated DMRS corresponding to a first type of PDCCH transmission resource;

[0162] Sequence-based indicator signals.

[0163] Using the PDCCH monitoring method described in an embodiment of the present invention, during the activation period of the terminal, the network side device sends an indication signal to the terminal, the indication signal carries monitoring indication information, and the sent indication signal is associated with the PDCCH monitoring opportunity, and is used to indicate whether the terminal needs to perform PDCCH monitoring on the associated PDCCH monitoring opportunity.

[0164] In one implementation mode, optionally, the network side device sends a dedicated DMRS to the terminal as the indication signal, and optionally, the dedicated DMRS is a DMRS corresponding to the first type of PDCCH transmission resources.

[0165] Specifically, the dedicated DMRS is a function of the dedicated ID corresponding to the first type of PDCCH transmission resource, that is, the dedicated DMRS is dedicated to the first type of transmission resource. Optionally, the initial value of the DMRS scrambling sequence corresponding to the first type of PDCCH transmission resource can be configured as a dedicated value, or a RNTI dedicated to a low-latency service can be configured as the initial value of the DMRS scrambling sequence, or the dedicated RNTI configured for the service corresponding to the first type of PDCCH transmission resource is used as the initial value of the DMRS scrambling sequence, and the dedicated RNTI is used to generate the dedicated DMRS.

[0166] Optionally, in the PDCCH monitoring method described in the embodiment of the present invention, during the activation period of the terminal, each PDCCH monitoring opportunity corresponding to the first type of PDCCH transmission resource includes DMRS as the indication signal for carrying monitoring indication information.

[0167] For example, when the base station, i.e., the network-side device, configures CORESET#n through high-level dedicated signaling, a parameter is configured to implicitly or explicitly indicate the CORESET type, and the type of CORESET is indicated to distinguish whether CORESET#n supports PDCCH monitoring reduction. Specifically, the CORESET type is implicitly or explicitly indicated as the first type through high-level dedicated signaling, that is, the first type supports PDCCH monitoring reduction, and it is necessary to detect the resource type of the indication signal carrying the monitoring indication information on the corresponding PDCCH monitoring opportunity. Among them, the indication method of the CORESET type can refer to the above description, which will not be described in detail here.

[0168] When CORESET#n is of the first type and supports PDCCH monitoring reduction, when PDCCH is sent in CORESET#n, a dedicated DMRS is sent in the CORESET to instruct the terminal to monitor PDCCH; if CORESET#n is of the second type or is not configured as the first type, the existing PDCCH sending behavior is maintained.

[0169] In another implementation manner, when the network side device configures the search space through high-layer signaling, the search space type is implicitly or explicitly indicated through the configuration parameters of the search space, where the type is used to distinguish whether the search space supports PDCCH monitoring reduction.

[0170] Specifically, when the search space is configured as the first type, in order to support PDCCH monitoring reduction, it is necessary to detect the indication signal carrying monitoring indication information on the corresponding PDCCH monitoring opportunity. Specifically, when sending PDCCH in the search space, a dedicated DM-RS is sent in the CORESET corresponding to the search space as an indication signal to indicate whether the terminal performs PDCCH monitoring; if the search space is the second type or is not configured as the first type, the existing PDCCH sending behavior is maintained.

[0171] In another implementation manner of the PDCCH monitoring method described in the embodiment of the present invention, during the activation period of the terminal, the PDCCH monitoring opportunity corresponding to each first type of PDCCH transmission resource includes a sequence-based indication signal for carrying monitoring indication information.

[0172] Optionally, the sequence-based indication signal is a dedicated signal corresponding to the first type of PDCCH transmission resources, or is a dedicated signal corresponding to the terminal.

[0173] Optionally, the sending resource location of the sequence-based indication signal can be associated with the PDCCH listening opportunity through protocol preset, and the preset resources used to carry the indication signal and the corresponding PDCCH listening opportunity are separated by a preset number of OFDM symbols in the time domain; or, the preset resources and the sending resources of the PDCCH listening opportunity are frequency division multiplexed.

[0174] For example, when the network side device configures CORESET#n through high-level dedicated signaling, a parameter is configured to implicitly or explicitly indicate the CORESET type, and the type of CORESET is indicated to distinguish whether CORESET#n supports PDCCH monitoring reduction. Specifically, the CORESET type is implicitly or explicitly indicated as the first type through high-level dedicated signaling, that is, the first type supports PDCCH monitoring reduction, and it is necessary to detect the resource type of the indication signal carrying the monitoring indication information on the corresponding PDCCH monitoring opportunity.

[0175] When CORESET#n is of the first type and supports PDCCH monitoring reduction, when PDCCH is sent within CORESET#n, a sequence signal is sent on the preset resources corresponding to the PDCCH sending position to instruct the terminal to perform PDCCH monitoring; if CORESET#n is of the second type or is not configured as the first type, the existing PDCCH sending behavior is maintained.

[0176] In another implementation manner, when the network side device configures the search space through high-layer signaling, the search space type is implicitly or explicitly indicated through a search space parameter, where the type is used to distinguish whether the search space supports PDCCH monitoring reduction.

[0177] Specifically, when the search space is configured as the first type, in order to support PDCCH monitoring reduction and to indicate the need to detect an indication signal carrying monitoring indication information on a corresponding PDCCH monitoring opportunity, when sending PDCCH within the search space, a sequence signal is sent on the preset resources corresponding to the PDCCH sending position as an indication signal for PDCCH monitoring; if the search space is of the second type or is not configured as the first type, the existing PDCCH sending behavior is maintained.

[0178] In the PDCCH monitoring method described in the embodiment of the present invention, optionally, the preset resource carrying the indication signal is associated with one PDCCH monitoring opportunity, or the preset resource carrying the indication signal is associated with at least two PDCCH monitoring opportunities.

[0179] Optionally, when the preset resource carrying the indication signal is associated with at least two PDCCH monitoring opportunities, performing PDCCH monitoring according to the monitoring indication information includes:

[0180] Determining, according to the monitoring indication information, whether at least two PDCCH monitoring opportunities associated with the preset resource need to perform PDCCH monitoring;

[0181] When it is determined that at least two PDCCH monitoring opportunities need to perform PDCCH monitoring, PDCCH monitoring is performed on each PDCCH monitoring opportunity.

[0182] Based on the above, the specific process of using the PDCCH monitoring method described in the embodiment of the present invention when applied to a terminal is described below.

[0183] In one implementation mode, the base station sends an indication signal by sending a dedicated DMRS to instruct the terminal to monitor the PDCCH.

[0184] In this implementation, the terminal obtains the type of PDCCH transmission resource according to the CORESET / search space parameters configured by the base station.

[0185] If the type of the PDCCH transmission resource is the first type, the terminal first detects the DMRS on all PDCCH monitoring opportunities determined by the first type of PDCCH transmission resources during the activation period, and when a dedicated DM-RS is detected, monitors the PDCCH on the corresponding PDCCH monitoring opportunity; when a non-dedicated DM-RS is detected or no DMRS is detected, skips the corresponding monitoring opportunity;

[0186] If the PDCCH sending resource is of the second type or is not configured as the first type, the terminal maintains the existing PDCCH monitoring behavior.

[0187] Optionally, the terminal detects that the dedicated DM-RS sequence sent by the base station is a function of a dedicated ID corresponding to the first type of PDCCH transmission resource.

[0188] For example, in one implementation mode, the terminal obtains the type of CORESET resource through the CORESET#n parameter configured by the base station. If CORESET#n is of the first type, it means that PDCCH monitoring reduction is supported. The terminal first detects DMRS on each PDCCH monitoring opportunity corresponding to CORESET#n during the activation period. If a dedicated DM-RS is detected, the PDCCH is monitored in the corresponding PDCCH monitoring opportunity; if no DMRS is detected or a non-dedicated DMRS is detected, the corresponding PDCCH monitoring opportunity is skipped. If CORESET#n is of the second type or is not configured as the first type, and PDCCH monitoring reduction is not supported, the terminal maintains the existing PDCCH monitoring behavior.

[0189] In another implementation mode, the terminal obtains the search space type through the search space parameters configured by the base station. If the search space is of the first type, it indicates that PDCCH monitoring reduction is supported, and the terminal first performs DMRS detection on all PDCCH monitoring opportunities corresponding to the search space during the activation period. If a dedicated DM-RS is detected, the PDCCH is monitored in the corresponding PDCCH monitoring opportunity; if no DM-RS is detected or a non-dedicated DM-RS is detected, the corresponding PDCCH monitoring opportunity is skipped. If the search space is of the second type or is not configured as the first type, PDCCH monitoring reduction is not supported, and the terminal maintains the existing PDCCH monitoring behavior.

[0190] In another embodiment, the base station sends an indication signal by sending a sequence-based indication signal (such as a time reference signal (TRS)) to instruct the terminal to monitor the PDCCH, wherein the sending resource of the sequence-based indication signal is associated with the PDCCH monitoring opportunity.

[0191] When this implementation mode is adopted, the terminal obtains the PDCCH transmission resource type according to the CORESET / search space parameters configured by the base station.

[0192] If the type of PDCCH sending resource is the first type, the terminal first detects the sequence signal on the preset resources corresponding to all PDCCH monitoring opportunities determined by the first type of PDCCH sending resources during the activation period, and when the sequence signal is detected, monitors the PDCCH on the corresponding PDCCH monitoring opportunity; when the sequence signal is not successfully detected, skips the corresponding PDCCH monitoring opportunity.

[0193] If the PDCCH sending resource type is the second type or is not configured as the first type, the terminal maintains the existing PDCCH monitoring behavior.

[0194] In this implementation, an example is given, in which one implementation, the terminal learns the CORESET type through the CORESET#n parameter configured by the base station. If it is the first type, PDCCH monitoring reduction is supported, the terminal determines the PDCCH monitoring opportunity position through CORESET#n and the corresponding search space, and detects the indication signal for indicating PDCCH monitoring on the corresponding preset resource of the PDCCH monitoring opportunity. If the indication signal is successfully detected, the PDCCH is monitored; otherwise, the PDCCH monitoring opportunity is skipped. If it is the second type or is not configured as the first type, PDCCH monitoring reduction is not supported, and the terminal maintains the existing PDCCH monitoring behavior.

[0195] In another implementation mode, the terminal obtains the search space type through the search space parameters configured by the base station. If it is the first type, PDCCH monitoring reduction is supported, the terminal determines the PDCCH monitoring opportunity through the search space and the corresponding CORESET, detects the PDCCH monitoring indication signal on the preset resource corresponding to the PDCCH monitoring opportunity, and if the indication signal is successfully monitored, the PDCCH is monitored; otherwise, the PDCCH monitoring opportunity is skipped. If it is the second type or is not configured as the first type, PDCCH monitoring reduction is not supported, and the terminal maintains the existing PDCCH monitoring behavior.

[0196] The following is an example of the specific implementation process of the PDCCH monitoring method described in the embodiment of the present invention.

[0197] Implementation Method 1

[0198] In the first implementation mode, the type of CORESET is explicitly configured as the first type, and monitoring indication information is carried by a dedicated DMRS to instruct the terminal to perform PDCCH monitoring in the corresponding PDCCH monitoring opportunity.

[0199] Specifically, the terminal reports the terminal capability, and for different terminal capabilities, the base station classifies the PDCCH transmission resources accordingly. Based on the terminal capability, the base station can configure all PDCCH transmission resources as one type, such as the first type, using high-level signaling, or configure some PDCCH transmission resources as the first type and some transmission resources as the second type, or only configure some PDCCH transmission resources as the first type, and other PDCCH transmission resources are not configured. For the convenience of description, all embodiments in this document assume that PDCCH transmission resources are divided into the first type and the second type, but the protection scope of the present invention is not limited to this.

[0200] When the base station configures CORESET#n for the terminal through high-level signaling, a parameter configuration is used to indicate whether PDCCH monitoring reduction is supported. This parameter can directly configure the resource type of CORESET#n (can be configured as the first type: support PDCCH monitoring reduction; second type: do not support PDCCH monitoring reduction). For the first type, the base station configures the initial value of the DMRS scrambling sequence corresponding to the CORESET as a dedicated value, and can also configure a dedicated RNTI and use it as the initial value of the scrambling sequence to generate a dedicated DMRS. When the base station sends PDCCH within the CORESET, it sends a dedicated DMRS as an indication signal; for the second type of PDCCH transmission resources, the base station maintains the existing technical behavior and does not send an indication signal.

[0201] The terminal directly obtains the type of PDCCH sending resources of CORESET through the configuration parameters of CORESET, determines whether PDCCH monitoring reduction is supported, and performs corresponding PDCCH monitoring behavior, that is, for the first type of PDCCH sending resources, the terminal first detects the dedicated DMRS on all PDCCH monitoring opportunities during the activation period, and only monitors the corresponding PDCCH if the dedicated DMRS is successfully detected; for the second type of PDCCH sending resources, the terminal maintains the existing PDCCH monitoring behavior.

[0202] Specifically, the terminal reports the terminal capability, and the base station classifies the PDCCH transmission resources configured for the terminal accordingly according to the terminal capability. The base station configures the PDCCH transmission resources into the first type and the second type through high-level signaling. Optionally, the first type of PDCCH transmission resources can be used for low-latency services, and the second type of PDCCH transmission resources can be used for other services.

[0203] For the base station side:

[0204] The base station configures CORESET#n through high-level signaling, such as through resource indication type Resource-Type parameter configuration.

[0205] If Resource-Type is configured as the first type, it indicates that CORESET#n can support PDCCH monitoring reduction;

[0206] If Resource-Type is configured as the second type, it indicates that CORESET#n does not support PDCCH monitoring reduction.

[0207] Optionally, when configuring the DMRS scrambling sequence initial value corresponding to the first type of CORESET, the base station configures the DMRS scrambling sequence initial value as a dedicated value, and may directly agree on a dedicated value by protocol, or may configure a dedicated RNTI as the DMRS scrambling sequence initial value to generate a dedicated DM-RS.

[0208] When sending PDCCH in the first type of CORESET, the dedicated DMRS is mapped to the corresponding resource, and the dedicated DMRS is sent as an indication signal. When sending PDCCH in the second type of CORESET, the base station maintains the existing behavior.

[0209] For the terminal side:

[0210] The terminal obtains the configuration of CORESET#n through high-level signaling, and directly learns the sending resource type through the parameter Resource-Type, and learns whether PDCCH monitoring reduction is supported.

[0211] If Resource-Type is the first type, the terminal first performs DMRS detection on all PDCCH monitoring opportunities corresponding to CORESET#n during the activation period;

[0212] If the dedicated DM-RS is successfully detected, it means that the base station has sent the PDCCH of the terminal, and the PDCCH monitoring is performed on the corresponding PDCCH monitoring opportunity;

[0213] If the dedicated DM-RS is not successfully detected, it means that the base station has not sent the PDCCH of the terminal, and this PDCCH monitoring opportunity is skipped.

[0214] If the Resource-Type is the second type, the terminal maintains the PDCCH monitoring behavior of the prior art in CORESET#n.

[0215] In conventional technology, each PDCCH blind detection must first assume the existence of DMRS, perform channel estimation, and then DCI decoding. It is considered successful only if the CRC check is correct. PDCCH blind detection is processed in parallel. For example, the base station is configured with the aggregation level and the number of candidate PDCCHs for each aggregation level. The terminal needs to blindly detect all candidate PDCCHs in parallel and cannot stop monitoring when it monitors PDCCH on a certain candidate PDCCH. Compared with the prior art, the method described in the embodiment of the present invention is adopted. For the first type of PDCCH transmission resources, before monitoring PDCCH, the terminal first performs extremely low-power DMRS detection to determine whether to perform high-power PDCCH monitoring, which can save a lot of unnecessary PDCCH monitoring power consumption of the terminal and achieve the purpose of terminal power saving. In addition, the advantage of using a dedicated DM-RS as an indication signal is that it can prevent the terminal from detecting the DMRS of other terminals on the CORESET that supports PDCCH monitoring reduction, resulting in the mistaken belief that the base station has sent the PDCCH of the terminal and unnecessary PDCCH monitoring. The specific reason is: if the base station configures the same DMRS scrambling initial value for different terminals, and the CORESET configuration overlaps, then when the terminal performs DMRS detection on candidate PDCCHs of different aggregation levels, it is possible that the terminal successfully detects DMRS on candidate PDCCHs of lower aggregation levels of other terminals, and will mistakenly believe that the base station has sent the PDCCH of the terminal, thereby performing unnecessary PDCCH monitoring. The present invention uses dedicated DM-RS as an indication signal, which can effectively avoid unnecessary PDCCH monitoring.

[0216] Implementation Method 2

[0217] In the second implementation mode, the CORESET type is implicitly configured to the terminal by configuring the DM-RS scrambling sequence initial value parameter; and the dedicated DMRS carries the monitoring indication information to instruct the terminal to perform PDCCH monitoring at the corresponding PDCCH monitoring opportunity.

[0218] Optionally, in this implementation, the base station and the terminal agree on a dedicated DM-RS scrambling initial value DMRS-dedicated-value.

[0219] When the base station configures CORESET#n for the terminal through high-level signaling, the DM-RS scrambling sequence initial value parameter pdcch-DMRS-ScramblingID is configured to a preset specified value PDCCH Monitoring Reduction-dedicated-value or a regular value to implicitly indicate the type of sending resource. Optionally, PDCCH Monitoring Reduction-dedicated-value can be a newly added dedicated RNTI, which can be configured to the terminal when configuring RNTI through high-level signaling.

[0220] Specifically, when the scrambling sequence initial value parameter of the demodulation reference signal DMRS is configured as PDCCH MonitoringReduction-dedicated-value, that is, configured as a preset designated value, it is used to indicate that the sending resource type is the first type and supports PDCCH monitoring reduction; when the scrambling sequence initial value parameter of the DMRS is configured as a normal value, it is used to indicate that the sending resource type is the second type and does not support PDCCH monitoring reduction.

[0221] For the first type of PDCCH transmission resources, when the base station sends PDCCH within CORESET, it sends a dedicated DMRS as an indication signal, and the dedicated DMRS is generated by PDCCH Monitoring Reduction-dedicated-value as the initial scrambling value; for the second type of PDCCH transmission resources, the base station maintains the existing technical behavior and does not send an indication signal.

[0222] The terminal indirectly learns the CORESET sending resource type by judging whether the CORESET configuration parameter pdcch-DMRS-ScramblingID is PDCCHMonitoringReduction-dedicated-value, determines whether PDCCH monitoring reduction is supported, and performs corresponding PDCCH monitoring behavior.

[0223] Specifically, the terminal reports the terminal capability, and the base station classifies the PDCCH transmission resources configured for the terminal accordingly according to the terminal capability. The base station configures the PDCCH transmission resources into the first type and the second type through high-level signaling. The first type of PDCCH transmission resources can be used for low-latency services, and the second type of PDCCH transmission resources can be used for other services.

[0224] Base station side:

[0225] The base station configures CORESET#n through dedicated high-layer signaling, and configures the DMRS scrambling sequence initial value parameter pdcch-DMRS-ScramblingID. If pdcch-DMRS-ScramblingID is configured as PDCCH MonitoringReduction-dedicated-value, it indicates that the sending resource type is the first type, and CORESET#n supports PDCCH monitoring reduction;

[0226] If pdcch-DMRS-ScramblingID is configured as a normal value, it indicates that the sending resource type is the second type and CORESET#n does not support PDCCH monitoring reduction.

[0227] The base station generates DM-RS by using PDCCH Monitoring Reduction-dedicated-value as the initial value of the scrambling sequence, and the DMRS is a dedicated DMRS. When sending PDCCH in the CORESET#n, the dedicated DMRS is mapped to the corresponding resource and the dedicated DMRS is sent as an indication signal. For the second type of PDCCH transmission resources, the base station maintains the existing behavior.

[0228] Terminal side:

[0229] The terminal obtains the configuration parameters of CORESET#n through high-level signaling, and indirectly learns whether PDCCH monitoring reduction is supported through the parameter pdcch-DMRS-ScramblingID, and performs corresponding PDCCH monitoring behavior. If pdcch-DMRS-ScramblingID is a normal value, the terminal maintains the PDCCH monitoring behavior of the existing technology in CORESET#n. If pdcch-DMRS-ScramblingID is PDCCH Monitoring Reduction-dedicated-value, the terminal first detects DMRS on the PDCCH monitoring opportunity in CORESET#n.

[0230] If the dedicated DM-RS is successfully detected, it means that the base station has sent the PDCCH of the terminal and is monitoring the PDCCH;

[0231] If the dedicated DM-RS is not successfully detected, it means that the base station has not sent the PDCCH of the terminal, and the PDCCH monitoring opportunity is skipped.

[0232] Since this embodiment uses a dedicated DM-RS as an indication signal, the scrambling initial sequence of the DMRS is in the CORESET configuration parameter, and the parameter pdcch-DMRS-ScramblingID is configured as a dedicated value, which can be used for scrambling of the dedicated DM-RS and can also be used to indicate the transmission resource type of the CORESET. In addition to having the same beneficial effects as the first embodiment, compared with the first embodiment using a newly added parameter to explicitly indicate the transmission resource type, the second embodiment uses an implicit method to indicate the transmission resource type, which can avoid increasing the signaling overhead.

[0233] Implementation Method 3

[0234] In the third implementation mode, the type of search space is configured, and monitoring indication information is carried by a dedicated DMRS to instruct the terminal to perform PDCCH monitoring in a corresponding PDCCH monitoring opportunity.

[0235] In this implementation, when the base station configures the search space for the terminal through high-level signaling, a parameter configuration is used to indicate whether PDCCH monitoring reduction is supported, and this parameter explicitly or implicitly indicates the search space resource type (first type: supporting PDCCH monitoring reduction; second type: not supporting PDCCH monitoring reduction). For the first type, when the base station sends PDCCH in the search space, it sends a dedicated DM-RS as an indication signal, and for the second type, the base station maintains the existing technical behavior and does not send an indication signal.

[0236] The terminal obtains the search space resource type through the configuration parameters of the search space, finds out whether PDCCH monitoring reduction is supported, and performs corresponding PDCCH monitoring behavior. That is, for the first type of PDCCH sending resources, the terminal first detects the dedicated DMRS on all its PDCCH monitoring opportunities. Only when the dedicated DMRS is successfully detected will it monitor the corresponding PDCCH; for the second type of PDCCH sending resources, the terminal maintains the existing PDCCH monitoring behavior.

[0237] Specifically, the terminal reports the terminal capability, and the base station classifies the PDCCH transmission resources configured for the terminal accordingly according to the terminal capability. The base station configures the PDCCH transmission resources into the first type and the second type through high-level signaling. The first type of PDCCH transmission resources can be used for low-latency services, and the second type of PDCCH transmission resources can be used for other services.

[0238] For the base station side:

[0239] When the base station configures the search space SS#n through dedicated high-level signaling, the configuration parameters indicate the PDCCH sending resource type. If the sending resource type is the first type, it indicates that the SS#n supports PDCCH monitoring reduction; if the sending resource type is the second type, it indicates that the SS#n does not support PDCCH monitoring reduction.

[0240] The base station generates a DM-RS using the initial value of the DM-RS scrambling sequence corresponding to the CORESET associated with SS#n, and maps it to the CORESET resource for transmission. For the first type, the DMRS is a dedicated DM-RS and serves as a PDCCH monitoring indication signal; for the second type, the DMRS is not used as an indication signal.

[0241] For the terminal side:

[0242] The terminal obtains the configuration parameters of the search space SS#n through high-level signaling, and obtains the transmission resource type of the search space. If the transmission resource type is the second type, the terminal maintains the PDCCH monitoring behavior of the prior art in the search space SS#n.

[0243] If the transmission resource type is the first type, the terminal first detects the DMRS in the PDCCH monitoring opportunity in SS#n;

[0244] If a dedicated DM-RS is detected, it indicates that the base station has sent the PDCCH of the terminal on the PDCCH monitoring opportunity and is monitoring the PDCCH;

[0245] If the dedicated DM-RS is not successfully detected, it means that the base station does not send the PDCCH of the terminal on the PDCCH monitoring opportunity and skips the corresponding PDCCH MO.

[0246] It should be noted that the beneficial effects of the method described in the third embodiment are the same as those of the first and second embodiments, and will not be described in detail here.

[0247] Implementation Method 4

[0248] In this implementation, the CORESET parameter notification type is configured to indicate PDCCH monitoring based on a sequence signal.

[0249] When the base station configures CORESET#n for the terminal through high-level signaling, a configuration parameter is used to identify the transmission resource type of CORESET#n, indicating whether PDCCH monitoring reduction is supported (first type: supporting PDCCH monitoring reduction; second type: not supporting PDCCH monitoring reduction). For the first type of PDCCH transmission resources, the base station determines the PDCCH monitoring opportunity according to the configured CORESET and the corresponding search space, and sends a sequence-based signal at the preset resource associated with the PDCCH monitoring opportunity as a PDCCH monitoring indication signal. Optionally, each PDCCH monitoring opportunity is associated with a preset resource for sending an indication signal.

[0250] The terminal determines the PDCCH monitoring opportunity through the configured CORESET and the corresponding search space, and obtains the type of configured sending resources through high-level signaling. For the first type, the terminal can also determine the location of the preset resource based on the relationship between the PDCCH monitoring opportunity and the preset resource. The terminal first detects the PDCCH monitoring indication signal on the preset resource, and determines whether to perform PDCCH monitoring in the corresponding PDCCH monitoring opportunity based on the detection result. For the second type, the terminal maintains the existing PDCCH monitoring behavior.

[0251] Specifically, the terminal reports the terminal capability, and the base station classifies the PDCCH transmission resources configured for the terminal accordingly according to the terminal capability. The base station configures the PDCCH transmission resources into the first type and the second type through high-level signaling. The first type of PDCCH transmission resources can be used for low-latency services, and the second type of PDCCH transmission resources can be used for other services.

[0252] For the base station side:

[0253] The base station configures CORESET#n through dedicated high-layer signaling, and the configuration parameters indicate the type of sending resources.

[0254] If the sending resource type is the first type, it indicates that CORESET#n supports PDCCH monitoring reduction;

[0255] If the sending resource type is the second type, it indicates that CORESET#n does not support PDCCH monitoring reduction.

[0256] The base station sends PDCCH on the PDCCH listening opportunity corresponding to CORESET#n. For the first type, when the base station sends PDCCH, it also needs to send a sequence-based indication signal on the preset resources associated with the PDCCH listening opportunity. The relationship between this preset resource position and the PDCCH listening opportunity can be offset OFDM symbols in the time domain, or frequency division multiplexing in the frequency domain.

[0257] For the terminal side:

[0258] The terminal obtains the configuration of CORESET#n through dedicated high-layer signaling and learns the transmission resource type of CORESET#n. If the transmission resource type is the second type, the terminal maintains the PDCCH monitoring behavior of the prior art in CORESET#n.

[0259] If the sending resource type is the first type, the terminal determines the PDCCH monitoring opportunity position according to CORESET#n and the corresponding search space, and performs sequence signal detection at the preset resource position corresponding to each PDCCH monitoring opportunity.

[0260] If the sequence-based indication signal sent by the base station is successfully detected, it indicates that the PDCCH of the terminal exists in the corresponding PDCCH monitoring opportunity, and the PDCCH is monitored;

[0261] If the sequence-based indication signal sent by the base station cannot be successfully detected, it is considered that the PDCCH of the terminal does not exist in the corresponding PDCCH monitoring opportunity, and the PDCCH monitoring opportunity is skipped.

[0262] Compared with the prior art, the method described in implementation mode 4 is adopted to send a sequence-based PDCCH monitoring indication signal at a preset resource position associated with PDCCH MO. The terminal can determine the position of the preset resource of the indication signal according to the position of the PDCCH monitoring indication signal, and avoid unnecessary high-energy consumption PDCCH monitoring through extremely low-energy consumption indication signal detection.

[0263] Implementation Method 5

[0264] In this implementation, the type of the search space is indicated by a configuration parameter of the search space, and PDCCH monitoring is indicated based on a sequence signal.

[0265] Among them, when the base station configures the search space SS#n for the terminal through high-level signaling, a configuration parameter is used to identify the transmission resource type of the search space SS#n, indicating whether PDCCH monitoring reduction is supported (first type: supporting PDCCH monitoring reduction; second type: not supporting PDCCH monitoring reduction). For the first type, the base station determines the PDCCH monitoring opportunity according to the configured search space and the corresponding CORESET, and sends a sequence-based signal as a PDCCH monitoring indication signal in the preset resource associated with the PDCCH monitoring opportunity. Each PDCCH monitoring opportunity is associated with a preset resource for sending an indication signal.

[0266] The terminal determines the PDCCH monitoring opportunity through the configured search space and the corresponding CORESET, and learns the type of configured sending resources through high-level signaling. For the first type, the terminal can also determine the location of the preset resource based on the relationship between the PDCCH monitoring opportunity and the preset resource. The terminal first detects the PDCCH monitoring indication signal on the preset resource, and determines whether to perform PDCCH monitoring in the corresponding PDCCH monitoring opportunity based on the detection result. For the second type, the terminal maintains the existing PDCCH monitoring behavior.

[0267] Specifically,

[0268] The terminal reports the terminal capability, and the base station classifies the PDCCH transmission resources configured for the terminal accordingly according to the terminal capability. The base station configures the PDCCH transmission resources into the first type and the second type through high-level signaling. The first type of PDCCH transmission resources can be used for low-latency services, and the second type of PDCCH transmission resources can be used for other services.

[0269] For the base station side:

[0270] The base station configures the search space SS#n through dedicated high-layer signaling, and the configuration parameters indicate the type of sending resources;

[0271] If the sending resource type is the first type, it indicates that the search space SS#n supports PDCCH monitoring reduction;

[0272] If the sending resource type is the second type, it indicates that the search space SS#n does not support PDCCH monitoring reduction.

[0273] The base station sends PDCCH in the PDCCH listening opportunity corresponding to the search space SS#n. For the first type, when the base station sends PDCCH, it also needs to send a sequence-based indication signal on the preset resources associated with the PDCCH listening opportunity. The relationship between this preset resource position and the PDCCH listening opportunity can be offset OFDM symbols in the time domain, or frequency division multiplexing in the frequency domain.

[0274] For the terminal side:

[0275] The terminal obtains the configuration of the search space SS#n through dedicated high-layer signaling, and learns the transmission resource type of the search space SS#n. If the transmission resource type is the second type, the terminal maintains the PDCCH monitoring behavior of the prior art in the search space SS#n.

[0276] If the sending resource type is the first type, the terminal determines the PDCCH monitoring opportunity position according to the search space SS#n and the corresponding CORESET, and performs sequence signal detection at the preset resource position corresponding to each PDCCH monitoring opportunity;

[0277] If the sequence-based indication signal sent by the base station is successfully detected, it indicates that the PDCCH of the terminal exists in the corresponding PDCCH monitoring opportunity, and the PDCCH is monitored;

[0278] If the sequence-based indication signal sent by the base station cannot be successfully detected, it is considered that the PDCCH of the terminal does not exist in the corresponding PDCCH MO, and the PDCCH monitoring opportunity is skipped.

[0279] It should be noted that the method described in the fifth embodiment has the same beneficial effects as the method described in the fourth embodiment, and will not be described in detail here.

[0280] By adopting the method described in the embodiment of the present invention, according to the terminal capability, all transmission resources can be configured as one of the types, or part of the transmission resources can be configured as the first type and part of the transmission resources can be configured as the second type. For the first type of PDCCH transmission resources, the indication signal is bound or associated with the PDCCH listening opportunity, and the terminal can determine the resource location of the indication signal according to the resource location of each PDCCH listening opportunity; the terminal detects the indication signal on each preset resource to determine whether to monitor the PDCCH in the corresponding PDCCH listening opportunity. Compared with the prior art that monitors PDCCH in all PDCCH listening opportunities of the terminal, the method described in the present invention avoids unnecessary PDCCH monitoring of the terminal through extremely low energy consumption PDCCH monitoring indication signal detection, eliminates the high energy consumption of unnecessary PDCCH monitoring, extends the battery life of the terminal and improves the user terminal experience.
