For this reason, the wireless network introduces more spectrum resources to provide more spectrum resources for communication; alternatively, more technologies are introduced into the wireless network to improve the utilization of the spectrum resources.
At this time, the wireless network may configure a plurality of available uplink resources for the terminal, which causes uncertainty in uplink resource usage of the terminal, and causes a problem of communication quality or efficiency degradation.
Disclosure of Invention
The embodiment of the application provides a method and a device for using uplink resources, so as to solve the problem of uncertainty of uplink resource use and improve communication quality or efficiency.
In a first aspect, a method for using uplink resources is provided, including: the network equipment generates first configuration information and second configuration information and sends the first configuration information and the second configuration information to the terminal. The terminal receives the first configuration information and the second configuration information. The first configuration information is used for configuring a first configuration authorization resource on a first uplink carrier for the terminal, and the second configuration information is used for configuring a second configuration authorization resource on a second uplink carrier for the terminal. And the terminal determines one of the first configuration authorized resource and the second configuration authorized resource as a target configuration authorized resource, and performs uplink transmission by adopting the target configuration authorized resource in a transmission period of the target configuration authorized resource. In this way, the terminal can use only one Physical Uplink Shared Channel (PUSCH) for uplink transmission at any time to ensure the communication quality.
In one implementation, the first configuration information and the second configuration information are configured such that the first configuration granted resource and the second configuration granted resource are staggered in a time domain, and when the first configuration granted resource is activated and a transmission cycle of the first configuration granted resource arrives, the first configuration granted resource is used for uplink transmission, and when the second configuration granted resource is activated and a transmission cycle of the second configuration granted resource arrives, the second configuration granted resource is used for uplink transmission.
At this time, the terminal determines the target configuration authorized resource, including: when the first configuration authorized resource is in an activated state and a transmission cycle of the first configuration authorized resource is reached, determining the first configuration authorized resource as a target configuration authorized resource; or when the second configuration authorized resource is in an activated state and the transmission cycle of the second configuration authorized resource is reached, determining that the second configuration authorized resource is the target configuration authorized resource.
The first configuration authorized resource and the second configuration authorized resource are configured by the network equipment so as to be not overlapped on the time domain, thereby reducing the implementation complexity of the terminal and saving the resources of the terminal.
Optionally, the first configuration information is configured to configure a first position of the first configuration authorized resource in the time domain, a first length occupied in the time domain, and a first period, and the second configuration information is configured to configure a second position of the second configuration authorized resource in the time domain, a second length occupied in the time domain, and a second period, so that when the first configuration authorized resource appears repeatedly in the first period from the first position, there is no overlapping portion of the periods with the second configuration authorized resource from the second position when the second configuration authorized resource appears repeatedly in the first period.
Optionally, the first location is a first time domain offset of the first configured granted resource relative to the time domain reference location; the second location is a second time domain offset of the second configured grant resource relative to the time domain reference location.
Optionally, the first position is different from the second position, the first length is the same as the second length, and the first period is the same as the second period.
In another implementation, the network device dynamically schedules the terminal on a target carrier, where the configuration grant resource on the target carrier is used for uplink transmission, where the target carrier is one of the first uplink carrier and the second uplink carrier. That is, the target configuration authorized resource is a configuration authorized resource on a target carrier, where the target carrier is a carrier on which the terminal is dynamically scheduled on the first uplink carrier and the second uplink carrier.
At this time, the network device dynamically schedules the terminal on which uplink carrier, which indicates that the current terminal is more suitable for performing uplink transmission on the carrier, so that the resource allocated and authorized by the terminal on the carrier can be used for uplink transmission, so that the terminal only uses one PUSCH for uplink transmission at any time, and data transmission failure caused by insufficient uplink transmission power of the terminal is reduced. Meanwhile, the terminal can upload and transmit on more appropriate carrier waves, and the communication quality is improved.
At this time, the above method may further include:
the network equipment sends authorization information to the terminal, wherein the authorization information is used for indicating the dynamic resources used for uplink transmission on the first uplink carrier or the second uplink carrier, and at the moment, the target configuration authorization resources are the configuration authorization resources on the uplink carrier where the dynamic resources are located. And the terminal receives the authorization information, determines a target carrier where the dynamic resource is located according to the authorization information, and determines the configuration authorization resource on the target carrier as the target configuration authorization resource.
Optionally, the grant information is used to activate the configured grant resources on the target carrier. Therefore, the authorization information can be directly utilized to achieve the purpose of activating and configuring the authorization resources, and the physical layer signaling is saved.
In yet another implementation, the first configuration authorized resource and the second configuration authorized resource have an overlapping portion in a time domain and are both in an active state, and in a transmission period of a target configuration authorized resource where the overlapping portion is located, the target configuration authorized resource is used for uplink transmission, where the target configuration authorized resource is one of the first configuration authorized resource and the second configuration authorized resource.
For example, when the first configuration authorized resource and the second configuration authorized resource are in an activated state and have an overlapping portion in a time domain, the terminal performs uplink transmission by using the target configuration authorized resource in a transmission period of the target configuration authorized resource where the overlapping portion is located.
Optionally, when the first configured authorized resource and the second configured authorized resource have an overlapping portion in the time domain, the terminal may determine the target configured authorized resource by:
and the terminal determines a target configuration authorized resource according to the downlink channel quality, wherein when the downlink channel quality is greater than a threshold, the target configuration authorized resource is a first configuration authorized resource, or when the downlink channel quality is less than the threshold, the target configuration authorized resource is a second configuration authorized resource, or when the downlink channel quality is equal to the threshold, the target configuration authorized resource is the first configuration authorized resource or the second configuration authorized resource. Wherein, the first uplink carrier is a non-supplementary uplink (non-SUL) carrier, and the second uplink carrier is a Supplementary Uplink (SUL) carrier; alternatively, the first and second electrodes may be,
the target configuration authorized resource is predefined as a first configuration authorized resource; alternatively, the first and second electrodes may be,

the target configuration authorized resource is the configuration authorized resource which arrives at the first in the first configuration authorized resource and the second configuration authorized resource; alternatively, the first and second liquid crystal display panels may be,

The terminal selects the target configuration authorized resource according to the downlink channel quality, can configure the configuration authorized resource, the selection of which is more suitable for the actual situation of the network, and therefore can improve the communication quality. The predefined mode is simpler, and the network device can know which carrier the configuration authorized resource used by the terminal is on, so that the terminal can receive the configuration authorized resource only on the carrier, and the resource consumption of the network device is reduced. The random selection mode leaves the terminal with great flexibility. By adopting the mode of allocating authorized resources which arrives firstly, the transmission efficiency can be improved, and the data transmission time delay can be reduced. By adopting the network equipment indication mode, the implementation complexity of the terminal can be reduced, and the network equipment determines which carrier is used for configuring the authorized resources. In addition, the network device can receive uplink data only on the carrier indicated by the network device in the transmission period in which the overlapping part is located, thereby reducing resource consumption of the network device.
When the target configuration authorized resource is the configuration authorized resource indicated by the network device to the terminal, the method further comprises the following steps: the network equipment sends indication information to the terminal, wherein the indication information is used for indicating the target configuration authorized resource or the uplink carrier where the target configuration authorized resource is located; the terminal receives the indication information from the network equipment and determines the configuration of the authorized resources according to the indication information.

3) The term "plurality" means two or more, and the like. "/" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., A/B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.
Please refer to fig. 1, which is a schematic diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the terminal 130 accesses a wireless network to acquire a service of an external network (e.g., the internet) through the wireless network or to communicate with other terminals through the wireless network. The wireless network includes a RAN110 and a Core Network (CN) 120, where the RAN110 is used to access terminals 130 to the wireless network and the CN120 is used to manage the terminals and provide a gateway for communication with external networks.
Please refer to fig. 2, which is a schematic diagram of a network architecture according to an embodiment of the present application. As shown in fig. 2, the network architecture includes CN equipment and RAN equipment. The RAN device includes a baseband device and a radio frequency device, where the baseband device may be implemented by one node or by multiple nodes, and the radio frequency device may be implemented independently by being pulled away from the baseband device, may also be integrated in the baseband device, or may be partially pulled away and partially integrated in the baseband device. For example, in a Long Term Evolution (LTE) communication system, a RAN equipment (eNB) includes a baseband device and a radio frequency device, where the radio frequency device may be remotely located with respect to the baseband device, e.g., a Remote Radio Unit (RRU) is remotely located with respect to a BBU.
RAN equipment may implement functions of protocol layers such as Radio Resource Control (RRC), packet Data Convergence Protocol (PDCP), radio Link Control (RLC), and Media Access Control (MAC) by one node; or the functions of these protocol layers may be implemented by multiple nodes; for example, in an evolved structure, a RAN device may include a Centralized Unit (CU) and a Distributed Unit (DU), and a plurality of DUs may be controlled centrally by one CU. As shown in fig. 2, the CU and the DU may be divided according to protocol layers of the radio network, for example, functions of a PDCP layer and above protocol layers are provided in the CU, and functions of protocol layers below the PDCP layer, for example, functions of an RLC layer and a MAC layer, are provided in the DU.
This division of the protocol layers is only an example, and it is also possible to divide the protocol layers at other protocol layers, for example, at the RLC layer, and the functions of the RLC layer and the protocol layers above are set in the CU, and the functions of the protocol layers below the RLC layer are set in the DU; alternatively, the functions are divided into some protocol layers, for example, a part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are provided in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are provided in the DU. In addition, the processing time may be divided in other manners, for example, by time delay, a function that needs to satisfy the time delay requirement for processing is provided in the DU, and a function that does not need to satisfy the time delay requirement is provided in the CU.
In addition, the radio frequency device may be remote, not placed in the DU, or may be integrated in the DU, or may be partially remote and partially integrated in the DU, which is not limited herein.
With continued reference to fig. 3, with respect to the architecture shown in fig. 2, the control plane (UP) and the User Plane (UP) of the CU may be separated and implemented by being divided into different entities, namely a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity).
In the above network architecture, the signaling generated by the CU may be transmitted to the terminal through the DU, or the signaling generated by the terminal may be transmitted to the CU through the DU. The DU may pass through the protocol layer encapsulation directly to the terminal or CU without parsing the signaling. In the following embodiments, if transmission of such signaling between the DU and the terminal is involved, in this case, the transmission or reception of the signaling by the DU includes such a scenario. For example, the signaling of the RRC or PDCP layer is finally processed as the signaling of the PHY layer to be transmitted to the terminal, or converted from the received signaling of the PHY layer. Under this architecture, the signaling of the RRC or PDCP layer can also be considered to be sent by the DU, or by the DU and the radio frequency.
In the following embodiments, the signaling may also be referred to as messages.
In the above embodiment, the CU is divided into the network device on the RAN side, and in addition, the CU may also be divided into the network device on the CN side, which is not limited herein.
The apparatus in the following embodiments of the present application may be located in a terminal or a network device according to the functions implemented by the apparatus. When the above structure of CU-DU is adopted, the network device may be a CU node, or a DU node, or a RAN device including the CU node and the DU node.
At present, the number of terminals accessing a wireless network is increasing, the service types of the terminals are also increasing, and limited frequency spectrum resources cannot meet the requirement. New Radio (NR) (also known as 5G) access technologies therefore support spectrum operation above 3 GHz. The frequency band higher than 3GHz is referred to as a higher frequency band, and the frequency band lower than 3GHz (including 3 GHz) is referred to as a lower frequency band. The higher the operating frequency band, the greater the path loss of the wireless signal. When the NR operates in a frequency band above 3GHz, the network device can compensate for the path loss by increasing the transmission power in the downlink direction, thereby ensuring downlink coverage. In the uplink direction, the uplink coverage is limited due to the limited terminal power. In order to improve uplink coverage of a higher frequency band scene, a Supplemental Uplink (SUL) carrier of a lower frequency band may be configured for the terminal. After the SUL carrier is configured, the serving cell of the terminal is configured with one downlink carrier (e.g., 3.5 GHz) and two uplink carriers (e.g., non-SUL carrier of 3.5GHz and SUL carrier of 1.8 GHz).
Please refer to fig. 4, which is a schematic diagram of a scenario in which SUL carriers are configured according to an embodiment of the present application. As shown in fig. 4, the terminal is configured with two carriers in the uplink direction, one is a SUL carrier of a lower frequency band, the other is a non-SUL (non-SUL) carrier of a higher frequency band, and the non-SUL carrier of the higher frequency band is configured in the downlink direction. Wherein the uplink coverage of non-SUL carrier waves of higher frequency band is limited, so SUL carrier waves are configured.
In a scenario where the SUL is configured, part or all of the frequency resources may be activated on the SUL carrier and the non-SUL carrier, respectively. This activated frequency resource is for example called bandwidth part (BWP or BP). Although the terminal may be configured with two uplink carriers and frequency resources may be activated on both uplink carriers. However, for a serving cell of a terminal, because the uplink transmission power of the terminal is limited, if the terminal performs uplink data transmission on two resources overlapped in time domain simultaneously, transmission failure may be caused because the uplink transmission power is insufficient. Therefore, when the terminal uses the uplink resource, only the frequency resource on one uplink carrier is used for uplink transmission at any time; that is, it is necessary to provide an uplink resource utilization method, so that a serving cell only uses one Physical Uplink Shared Channel (PUSCH) for uplink transmission at any time.
The terminal can perform dynamic scheduling or non-dynamic scheduling on the uplink resource usage by the network device. In a dynamic scheduling scenario, a network device allocates uplink resources to a terminal, and indicates the allocated uplink resources to the terminal through Downlink Control Information (DCI). Thus, the network device can ensure that only one of the two uplink carriers of the serving cell configured with the SUL carrier performs PUSCH transmission at any time. In a non-dynamic scheduling scenario, the network device configures an authorized resource for the terminal, where the configured authorized resource may be referred to as a configured authorized resource, which is also referred to as a configured grant (configured grant). Currently, there are two types of configuration grants, namely configuration grant Type 1 (configured grant Type 1) and configuration grant Type 2 (configured grant Type 2). Configuring, by a network device, a configuration authorization type 1 and a configuration authorization type 2 to a terminal through RRC signaling, where a resource of the configuration authorization type 1 is provided to the terminal through the RRC signaling, that is, the configuration authorization type 1 is an uplink authorization provided to the terminal through the RRC signaling by the network device, and is stored as a configuration uplink authorization (configured uplink grant) by the terminal; the resource of the configuration grant type 2 is provided to the terminal by the network device through a Physical Downlink Control Channel (PDCCH), that is, the configuration grant type 2 is provided to the terminal by the network device through the Physical Downlink Control Channel (PDCCH), and is stored or cleared by the terminal as the configuration uplink grant, which is activated or deactivated by a physical layer or layer 1 (L1) signaling. The configuration grant type 1 may also be referred to as a Grant Free (GF) resource, and the configuration grant type 2 may also be referred to as a semi-persistent scheduling (SPS) resource.
The configuration authorization resource can be configured for each BWP, and when the BWP is activated, the terminal can use the GF resource configured on the BWP for uplink transmission; alternatively, after the BWP is activated and the SPS resources on the BWP are also activated, the terminal may use the SPS resources configured on the BWP for uplink transmission. In a scenario where the SUL is configured, active BWPs are both on the SUL carrier and the non-SUL carrier, and if configuration authorization resources are both on the active BWPs on the SUL carrier and the non-SUL carrier, the configuration authorization resources on the BWPs activated on the two uplink carriers may overlap in a time domain. At this time, the terminal has a situation that uplink resources on two carriers can be used for uplink transmission, however, the transmission power of the terminal is limited, and if the uplink resources on two carriers are used for simultaneous transmission, the signal quality may be reduced due to insufficient transmission power, and the network device cannot correctly analyze the signal.
Take the configuration of grant type 1, i.e. GF resources as an example. Please refer to fig. 5, which is a schematic diagram illustrating that GF resources on two active BWPs overlap in a temporal domain in a SUL configuration scenario according to an embodiment of the present application. As shown in fig. 5, the terminal is configured with an SUL carrier and a non-SUL carrier; wherein BWP1 on the non-SUL carrier is configured with GF resources, BWP2 is not configured with GF resources; BWP1 'on the SUL carrier is configured with GF resources and BWP2' is not configured with GF resources. BWP1 and BWP1 'are activated and there is an overlapping portion (or overlapping area) of the GF resources on BWP1 and BWP1' in the time domain. That is, the terminal may use the GF resources on BWP1 and BWP1' for uplink transmission in the overlapping portion, however, the transmit power of the terminal is limited, and if the GF resources on the two carriers are used for simultaneous transmission, the signal quality may be degraded due to insufficient transmit power, and the network device may not correctly resolve the problem. SPS resources are similar to the above, and the difference is that for GF resources, after BWP is activated, GF resources on the BWP can be used, and for SPS resources, after BWP is activated, SPS resources on the BWP are used after activated by physical layer signaling; similar to the GF resource, the SPS resources on the two uplink carriers are simultaneously in an active state and have problems caused by overlapping in a time domain, and are not described again here. In addition, the SPS resources in the following embodiments of the present application refer to uplink SPS resources.
Therefore, the embodiment of the application provides an uplink resource using method, so that a terminal only uses one PUSCH for uplink transmission at any time to ensure the communication quality. When the terminal is configured with two uplink carriers and both the two uplink carriers have the configuration authorization resources, the terminal determines one of the configuration authorization resources as the target configuration authorization resource. And in the transmission period of the target configuration authorized resource, the target configuration authorized resource is adopted for uplink transmission. In this way, the terminal can use only one PUSCH for uplink transmission at any time to ensure the communication quality.
Please refer to fig. 6, which is a schematic diagram illustrating an uplink resource using method according to an embodiment of the present application. As shown in fig. 6, the method includes the steps of:
s610: the terminal receives first configuration information and second configuration information, wherein the first configuration information is used for configuring first configuration authorization resources on a first uplink carrier for the terminal, and the second configuration information is used for configuring second configuration authorization resources on a second uplink carrier for the terminal;
s620: the terminal determines one of the first configuration authorized resource and the second configuration authorized resource as a target configuration authorized resource;
s630: and the terminal adopts the target configuration authorized resource to perform uplink transmission in the transmission period of the target configuration authorized resource, namely, the target configuration authorized resource is utilized to send uplink information. The uplink information may include uplink data/uplink control information. The uplink control information refers to uplink information other than uplink data, for example, control signaling.
In the above step S610, the first configuration information and the second configuration information may be carried in one configuration message, or may be carried in different configuration messages, respectively. Optionally, the first uplink carrier may be an SUL carrier, and the second uplink carrier may be a non-SUL carrier; alternatively, the first uplink carrier may be a non-SUL carrier, and the second uplink carrier may be a SUL carrier. Thus, when the SUL is configured and the configuration authorization resources on both the SUL and non-SUL carriers are in an activated state, the terminal can use only one PUSCH for uplink transmission at any time to ensure the communication quality.
The method includes that a configuration authorization resource is configured for a network device in advance for a terminal, the configuration authorization resource is usually a periodic resource, and when the configuration authorization resource is in an activated state, the terminal can periodically use the configuration authorization resource to perform uplink transmission. The first and second configuration granted resources may be GF resources, or the first and second configuration granted resources may be SPS resources. Alternatively, the first configuration grant resource may be a GF resource, and the second configuration grant resource may be an SPS resource; alternatively, the first configured grant resource may be an SPS resource and the second configured grant resource may be a GF resource.
For the SPS resource, the network device may configure an SPS for the terminal through RRC signaling, and the configured parameter may include an SPS-Radio Network Temporary Identifier (RNTI), a period of the SPS resource, a number of processes using the SPS resource, and the like. The terminal configured with SPS can also perform dynamic scheduling, so whether the PDCCH is used for dynamic scheduling or SPS scheduling is distinguished by SPS-RNTI. The network equipment activates/deactivates SPS through the PDCCH scrambled by the SPS-RNTI, and the terminal is appointed with SPS resources at the same time of the SPS activation by the PDCCH, wherein the SPS resources periodically appear according to a period configured by RRC signaling. After the SPS configured cell/BWP is activated and physical layer signaling activating the SPS resources is received, the terminal may use the SPS resources for uplink transmission. Optionally, after the cell/BWP configured with SPS is activated, the terminal may use SPS resources for uplink transmission, so as to save physical layer signaling. At this point, SPS resources have been indicated to the terminal by the network device. Accordingly, after the SPS configured cell/BWP is deactivated, the SPS resources are also deactivated, i.e., in an inactive state. The first configuration information may refer to information carried by the PDCCH for specifying SPS resources, or to information carried by the PDCCH for specifying SPS resources and information carried by RRC signaling for configuring SPS.
The GF resources are different from SPS resources in that the RRC specifies periodic GF resources when configuring GF, and then the terminal can perform uplink transmission using the GF resources after the cell/BWP configured with GF is activated. The first configuration information may refer to information for configuring the GF carried by RRC signaling.
Optionally, the terminal may receive information for activating a first BWP on the first uplink carrier and information for activating a second BWP on the second uplink carrier, where the first BWP and the second BWP are configured with a first configuration authorized resource and a second configuration authorized resource. When the first BWP is activated, the first configuration granted resource is simultaneously activated (or active), i.e., may be used. When the second BWP is activated, the second configuration granted resources are simultaneously activated (or active), i.e., available for use. At this time, the first and second configuration grant resources may be GF resources, or may be SPS resources.
Or, the terminal may receive information for activating a first BWP on a first uplink carrier and information for activating a second BWP on a second uplink carrier, where the first BWP and the second BWP are configured with a first configuration authorized resource and a second configuration authorized resource. And then, the terminal receives first activation information and second activation information, wherein the first activation information is used for activating the first configuration authorized resource, and the second activation information is used for activating the second configuration authorized resource. At this time, the first and second configuration grant resources may be SPS resources.
It can be seen that, when the GF resource is activated in the frequency resource (e.g., cell, carrier, or BWP) where the GF resource is located, the GF resource is activated at the same time, and the SPS resource may be activated/deactivated in the same manner or by independent information.
The configuration authorized resource is activated, which means that the configuration authorized resource can be used, i.e. the configuration authorized resource is in an activated state.
In step S620, when the first configuration authorized resource and the second configuration authorized resource are in an active state and have an overlapping portion in the time domain, the terminal performs uplink transmission by using the target configuration authorized resource in the transmission period of the target configuration authorized resource where the overlapping portion is located. At this time, the terminal may determine the target configuration authorized resource in any one of the following manners.
The first mode is as follows: the way in which the terminal uses the configuration authorization resource is predefined. For example, the target configuration authorized resource is predefined as a first configuration authorized resource, where the first configuration authorized resource is, for example, a configuration authorized resource on an SUL carrier, that is, when the configuration authorized resource on the SUL carrier and the configuration authorized resource on a non-SUL carrier overlap in a time domain, the predefined terminal uses the configuration authorized resource on the SUL carrier for uplink transmission.
For another example, the target configuration authorized resource is predefined as a second configuration authorized resource, where the second configuration authorized resource is, for example, a configuration authorized resource on a non-SUL carrier, that is, when the configuration authorized resource on the SUL carrier and the configuration authorized resource on the non-SUL carrier overlap in a time domain, the predefined terminal uses the configuration authorized resource on the non-SUL carrier for uplink transmission.
The predefined mode is simple, and the network device can know which carrier the configuration authorized resource used by the terminal is on, so that the terminal can receive the configuration authorized resource only on the carrier, and the resource consumption of the network device is reduced.
The second mode is as follows: and the terminal randomly selects one configuration authorized resource from the first configuration authorized resource and the second configuration authorized resource as a target configuration authorized resource. This approach leaves the terminal with greater flexibility, but the network device is not aware of which carrier the configuration grant resource used by the terminal is on, and therefore receives on both carriers.
The third mode is as follows: and the terminal selects the configuration authorized resource which arrives firstly from the first configuration authorized resource and the second configuration authorized resource as the target configuration authorized resource. That is, the terminal uses the first arrived configuration grant resource for uplink transmission. By adopting the mode, the uplink transmission can be carried out by adopting the resource which arrives first, thereby improving the transmission efficiency and reducing the data transmission time delay.
For example, please refer to fig. 7, which is a schematic diagram of a first configuration authorized resource and a second configuration authorized resource provided in an embodiment of the present application. In this embodiment, taking the first configuration authorized resource as the configuration authorized resource on the non-SUL carrier and the second configuration authorized resource as the configuration authorized resource on the SUL carrier as an example, it can be seen from the figure that the first configuration authorized resource and the second configuration authorized resource have an overlapping part (or region) O in the time domain, and the second configuration authorized resource on the SUL carrier arrives before the first configuration authorized resource on the non-SUL carrier, and then the terminal determines that the second configuration authorized resource is the target configuration authorized resource. And in the transmission period T2 of the second configuration authorized resource where the overlapped part O is located, the second configuration authorized resource is adopted for uplink transmission. And in the transmission period T1 of the first configuration authorized resource where the overlapping part O is located, no uplink transmission is performed by using the first configuration authorized resource.
When the first configuration authorized resource and the second configuration authorized resource arrive at the same time, the target configuration authorized resource can be determined in the first manner or the second manner.
The fourth mode is as follows: the network device instructs the terminal to select which carrier to use for configuring the authorized resources, that is, the target configured authorized resources are the configured authorized resources that the network device instructs the terminal.
Please refer to fig. 8, which is a schematic diagram of another uplink resource using method according to an embodiment of the present application. Compared with the embodiment shown in fig. 6, the method also comprises the following steps:
s840: the terminal receives indication information from the network equipment, wherein the indication information is used for indicating the target configuration authorized resource or the uplink carrier where the target configuration authorized resource is located.
Step S620 in the embodiment shown in fig. 6 at this time can be realized by the following step S820.
S820: and the terminal determines the target configuration authorized resource according to the indication information.
The other steps S810 and S830 are similar to the steps S610 and S630 in the embodiment shown in fig. 6, and are not described again here.
The above indication information may be carried in a system message, RRC signaling, DCI, or group DCI (group DCI). Wherein the group DCI is for a group of terminals that use the same RNTI to listen to the group DCI. The implementation manner of the indication information is not limited, for example, the indication information may be a 1-bit (bit) information element, and when the information element is "1", the indication information element is used to indicate the first configuration grant resource or to indicate the first uplink carrier, and when the information element is "0", the indication information element is used to indicate the second configuration grant resource or to indicate the second uplink carrier. When the indication information indicates the first uplink carrier or the second uplink carrier, the terminal selects the configuration authorization resource on the uplink carrier indicated by the terminal as the target configuration authorization resource according to the indication information. The indication information may also be, for example, a carrier identifier, which is used to identify the first uplink carrier or the second uplink carrier.
By adopting the method, the implementation complexity of the terminal can be reduced, and the network equipment determines which carrier is used for configuring the authorized resource. In addition, the network device can receive uplink data only on the carrier indicated by the network device in the transmission period in which the overlapping part is located, thereby reducing resource consumption of the network device.
The introduction of the SUL can make up the deficiency of the uplink coverage of the high-frequency carrier, and when the terminal is positioned at the edge of the cell coverage, the SUL carrier can be used for reducing the data transmission failure caused by the deficiency of the uplink transmitting power. When the terminal is close to the network device, a higher data transmission rate can be obtained using the non-SUL carrier. The network device may determine the location of the terminal through channel quality reported by the terminal, for example, a Channel Quality Indicator (CQI), so as to determine a suitable uplink carrier, and then, the network device indicates the uplink carrier or a configuration authorization resource on the uplink carrier to the terminal, so that the terminal only uses one PUSCH for uplink transmission at any time, thereby reducing data transmission failure caused by insufficient uplink transmission power of the terminal.
At this time, in addition to performing the first configuration information and the second configuration information sent to the terminal and receiving the uplink information sent by the terminal on the target configuration authorized resource in the embodiment shown in fig. 6, the network device further performs: the network equipment determines a target uplink carrier and sends indication information to the terminal, wherein the indication information is used for indicating the target uplink carrier or configuration authorization resources on the target uplink carrier.
The fifth mode is as follows: and the terminal determines the target configuration authorization resource according to the downlink channel quality. At this time, step S620 shown in fig. 6 may include: and the terminal determines the target configuration authorization resource according to the downlink channel quality. When the downlink channel quality is greater than the threshold, the target configuration authorized resource is a first configuration authorized resource on the non-SUL carrier, or when the downlink channel quality is less than the threshold, the target configuration authorized resource is a second configuration authorized resource on the SUL carrier, or when the downlink channel quality is equal to the threshold, the target configuration authorized resource is the first configuration authorized resource on the non-SUL carrier or the second configuration authorized resource on the SUL carrier. . The channel quality threshold may be predefined by a protocol or configured to the terminal through RRC signaling.
The downlink channel quality may be obtained by the terminal by measuring a downlink reference signal on a downlink carrier, for example, reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ).
When two configuration authorized resources which are overlapped appear on the time domain, the terminal compares the downlink channel quality with the channel quality threshold to determine which configuration authorized resource is used. For example, when the downlink channel quality is greater than a given channel quality threshold, it indicates that the terminal is closer to the network device, and a higher data rate can be obtained by using the configuration authorization resource on the high-frequency non-SUL carrier, whereas, it indicates that the terminal is farther from the base station, and data transmission failure due to insufficient uplink power can be reduced by using the configuration authorization resource on the SUL carrier.
In step S630, the terminal performs uplink transmission, that is, sends uplink information, by using the target configuration authorized resource in the transmission period of the target configuration authorized resource where the overlapped part is located.
Referring to fig. 7, when the target configuration authorized resource is the configuration authorized resource on the non-SUL carrier, and the transmission cycle of the target configuration authorized resource where the overlapped part is located is T1, the first configuration authorized resource is used for uplink transmission at T1, and the second configuration authorized resource is no longer used for uplink transmission at T2. When the target configuration authorized resource is the configuration authorized resource on the SUL carrier, and the transmission cycle of the target configuration authorized resource where the overlapped part is located is T2, the second configuration authorized resource is adopted at T2 for uplink transmission, and the first configuration authorized resource is not adopted at T1 for uplink transmission. For example, for the non-overlapped part, when the transmission period of each configuration grant resource arrives, the corresponding configuration grant resource may be used for uplink transmission.
For example, when the first configuration authorized resource is in an activated state and a transmission cycle of the first configuration authorized resource arrives, the first configuration authorized resource is used for uplink transmission; or when the second configuration authorized resource is activated and the transmission period of the second configuration authorized resource is reached, the second configuration authorized resource is used for uplink transmission.
In the above embodiment, when there is a time domain overlap between the configuration grant resources on the first uplink carrier and the second uplink carrier, any one of the manners disclosed above is adopted to select the configuration grant resource on one uplink carrier, so that the terminal only uses one PUSCH for uplink transmission at any time, so as to ensure the communication quality. In another embodiment of the present application, the configuration grant resources on the first uplink carrier and the second uplink carrier may not be activated at the same time, so that the terminal uses only one PUSCH for uplink transmission at any time to ensure the communication quality.
For example, in one implementation, the network device dynamically schedules the terminal on which carrier, and then grants the resource using the configuration on which carrier. That is, in step S620 above, the target configuration authorized resource is a configuration authorized resource on a target carrier, where the target carrier is a carrier on which the terminal is dynamically scheduled on the first uplink carrier and the second uplink carrier. Dynamically scheduling a terminal refers to dynamically allocating resources for the terminal. The grant information for dynamically scheduling the terminal is, for example, DCI.
At this time, referring to fig. 9, compared to the embodiment shown in fig. 6, the method for using uplink resources further includes the following steps:
s940: the terminal receives authorization information from the network device, where the authorization information is used to dynamically schedule the terminal on the first uplink carrier or the second uplink carrier for uplink transmission, that is, the authorization information is used to indicate dynamic resources for uplink transmission on the first uplink carrier or the second uplink carrier. The authorization information is carried, for example, through DCI.
Step S620 in the embodiment shown in fig. 6 at this time can be realized by the following step S920.
S920: and the terminal determines the target carrier where the dynamic resource is located according to the authorization information, and determines the authorization resource configured on the target carrier as the target authorization resource.
The other steps S910 and S930 are similar to the steps S610 and S630 in the embodiment shown in fig. 6, and are not repeated here.
Optionally, the grant information for dynamically scheduling the terminal may be used to activate the configuration grant resource, for example, the configuration grant resource on the uplink carrier may take effect when receiving the DCI. The network device dynamically schedules the terminal on which uplink carrier, the configuration grant resource on the uplink carrier is activated (or valid). For example, if the current uplink carrier is the first uplink carrier and the configuration authorization resource on the first uplink carrier is valid, and the network device dynamically schedules the terminal on the second uplink carrier, the configuration authorization resource on the second uplink carrier is valid and the configuration authorization resource on the first uplink carrier is no longer valid. At this time, the activation information in the above embodiment may be omitted. Alternatively, the grant resources configured on the uplink carrier may be activated (or validated) only when the grant information (e.g., DCI) for dynamically scheduling the terminal is received and uplink transmission is actually performed.
For GF resources, the DCI includes authorization information, i.e., the GF resources may be considered to be activated. SPS resources may also be activated in this manner, which may save physical layer signaling and improve communication efficiency. Or, for the SPS resource, when the grant information and the activation information are included in the DCI, the SPS resource is considered to be activated, or when the network device determines the target carrier, only the activation information of the target carrier is transmitted.
At this time, in addition to performing the first configuration information and the second configuration information sent to the terminal and receiving the uplink information sent by the terminal on the target configuration authorized resource in the embodiment shown in fig. 6, the network device further performs: the network device determines a target carrier. The network equipment sends authorization information to the terminal; or the network equipment sends DCI to the terminal, wherein the DCI comprises authorization information and activation information; or the network equipment sends activation information to the terminal, and the activation information is used for activating the configuration authorization resources on the target carrier. The first may be for GF resources or SPS resources, the latter two cases may be for SPS resources. The network device can determine the target carrier according to the channel quality information reported by the terminal.
For the cell configured with the SUL, assuming that the configuration authorization resource on the current SUL carrier is valid, when the terminal receives the DCI which schedules the terminal on the non-SUL carrier for uplink transmission, the configuration authorization resource on the SUL carrier is no longer valid, and the configuration authorization resource on the non-SUL carrier is activated and can be used.
The introduction of the SUL can make up the deficiency of the uplink coverage of the high-frequency carrier, and when the terminal is positioned at the edge of the cell coverage, the SUL carrier can be used for reducing the data transmission failure caused by the deficiency of the uplink transmitting power. When the terminal is close to the network device, a higher data transmission rate can be obtained using the non-SUL carrier. The network device may determine a location of the terminal according to channel quality information, such as a Channel Quality Indicator (CQI), reported by the terminal, so as to perform dynamic scheduling on the terminal on an appropriate uplink carrier. Furthermore, the network device dynamically schedules the terminal on which uplink carrier, which indicates that the terminal is more suitable for uplink transmission on the carrier currently, so that the authorized resource configured on the carrier by the terminal can be used for uplink transmission, so that the terminal only uses one PUSCH for uplink transmission at any time, and data transmission failure caused by insufficient uplink transmission power of the terminal is reduced.
In addition, when the network device identifies that the carrier better suited for the terminal to perform uplink transmission changes through the channel quality information reported by the terminal, the network device can activate the configuration authorization resource on one carrier through a piece of DCI signaling, and simultaneously deactivate the configuration authorization resource on another carrier, so that the signaling overhead is low.
At this time, the network device may further perform: the target carrier is determined to be changed, for example, the target carrier is changed from the first uplink carrier to the second uplink carrier, or from the second uplink carrier to the first uplink carrier. And sending DCI to the terminal, wherein the DCI is used for activating the configuration authorization resources on the changed target carrier. For GF resources, the DCI includes grant information indicating dynamic resources for uplink transmission on the changed target carrier. Or, the DCI includes authorization information and activation information, where the authorization information is used to indicate a dynamic resource for uplink transmission on a changed target carrier, and the activation information is used to activate a configuration authorization resource on the changed target carrier. Or, the DCI includes activation information for activating the configuration grant resources on the changed target carrier. The first may be for GF resources or SPS resources, the latter two cases may be for SPS resources. The network device can determine the target carrier according to the channel quality information reported by the terminal.
In another implementation, the network device may configure the configuration grant resources on the first uplink carrier and the second uplink carrier to be staggered in a time domain, i.e., time division multiplexing (tdm). Therefore, the terminal only uses one PUSCH for uplink transmission at any time, and data transmission failure caused by insufficient uplink transmission power of the terminal is reduced.
Please refer to fig. 10, which is a schematic diagram of an uplink resource allocation method according to an embodiment of the present application. As shown in fig. 10, the method includes the steps of:
s101: the network equipment generates first configuration information and second configuration information, wherein the first configuration information is used for configuring first configuration authorization resources on a first uplink carrier for the terminal, and the second configuration information is used for configuring second configuration authorization resources on a second uplink carrier for the terminal;
s102: the network equipment sends first configuration information and second configuration information to the terminal;
s103: and the network equipment receives the uplink information sent by the terminal according to the first configuration information and the second configuration information.
When the authorized resource is configured as a GF resource or an SPS resource, the description of the first configuration information and the second configuration information is the same as the above embodiment, and is not repeated herein.
Optionally, the configuration of the first configuration information and the second configuration information enables the first configuration authorized resource and the second configuration authorized resource to be staggered in the time domain, that is, there is no overlap between the first configuration authorized resource and the second configuration authorized resource in the time domain. Therefore, the terminal only uses one PUSCH for uplink transmission at any time, and data transmission failure caused by insufficient uplink transmission power of the terminal is reduced.
In one configuration implementation, the first configuration information is used to configure a first position of the first configuration authorized resource in a time domain, a first length occupied in the time domain, and a first period; the second configuration information is used for configuring a second position of the second configuration authorized resource in the time domain, a second length occupied in the time domain, and a second period, so that when the first configuration authorized resource repeatedly appears in the first period from the first position, there is no overlapping portion with the second configuration authorized resource when the second configuration authorized resource repeatedly appears in the second period from the second position. The location of the configured grant resource in the time domain may be embodied by a time domain offset, for example, the first location of the first configured grant information in the time domain may be implemented by configuring a first time domain offset relative to a time domain reference location; the second location of the second configuration grant information in the time domain may be achieved by configuring a second time domain offset of the second configuration grant resource with respect to the time domain reference location. The selection of the time domain reference position may be flexibly selected according to needs, and optionally, for example, a position with a System Frame Number (SFN) of zero is selected as the time domain reference position.
Optionally, the first time domain offset and the second time domain offset are different, and the first period and the second period are the same. In addition, a first length occupied by the first configuration authorized resource in the time domain is the same as a second length occupied by the second configuration authorized resource in the time domain. This is only a simple implementation of configuration, and the present application is not limited to this, as long as the first configuration grant resource and the second configuration grant resource are staggered in time domain.
Please refer to fig. 11, which is a schematic diagram of a first configuration authorized resource and a second configuration authorized resource according to an embodiment of the present application. As shown in fig. 11, when the network device configures the first configuration authorized resource on the first uplink carrier, the time domain position offset 1, the time domain length 1, and the period 1 of the first configuration authorized resource are specified; and when the network device configures the second configuration authorized resource on the second uplink carrier, the time domain position offset 2, the time domain length 2 and the period 2 of the second configuration authorized resource are specified. By setting the positions of the configuration authorized resources on the first uplink carrier and the second uplink carrier in the time domain, the length occupied by the configuration authorized resources in the time domain, and the period, any two configuration authorized resources appearing on the activated BWP of the two uplink carriers are not overlapped in the time domain. For example, the RRC sets the grant free resource periods and the time domain lengths on the two uplink carriers to be the same, but sets the time domain position offsets to be different.
In the SUL scenario, one of the uplink carriers is a SUL carrier, and the other uplink carrier is a non-SUL carrier.
When the grant resource is configured as a GF resource, the location of the grant resource in the time domain, the length occupied in the time domain, and the period may be configured through RRC signaling. For example, the first configuration authorized resource and the second configuration authorized resource are both GF resources, and the network device configures, through RRC signaling, a position of the first configuration authorized resource in the time domain, a length occupied in the time domain, and a period, and configures, through RRC signaling, a position of the second configuration authorized resource in the time domain, a length occupied in the time domain, and a period. The positions of the first configuration authorized resource and the second configuration authorized resource in the time domain, the occupied length of the time domain and the period of the time domain can be configured through the same RRC signaling, or the information can be configured through different RRC signaling.
In addition, for the GF resource, the GF resource may be used after the BWP in which the GF resource is located is activated, so that a separate signaling is not required to activate the GF resource.
When the grant resource is configured as an SPS resource, the period of the grant resource may be configured through RRC signaling, and the position in the time domain and the occupied length in the time domain may be configured through physical layer signaling, for example, DCI. For example, the first configuration authorized resource and the second configuration authorized resource are SPS resources, the network device configures a period of the first configuration authorized resource through RRC signaling, and configures a position of the first configuration authorized resource in a time domain and a length of the first configuration authorized resource in the time domain through physical layer signaling; and configuring the period of the second configuration authorized resource through RRC signaling, and configuring the position of the second configuration authorized resource on the time domain and the length occupied by the second configuration authorized resource on the time domain through physical layer signaling. And as to whether the signaling configuring the first configuration authorized resource and the signaling configuring the second configuration authorized resource are the same signaling or different signaling, no application is made for limitation.
Furthermore, for SPS resources, the SPS resources on BWP may be activated through physical layer signaling after BWP is activated. And SPS resources on both uplink carriers may be activated. The physical layer signaling is, for example, DCI.
The first configuration authorized resource and the second configuration authorized resource are configured by the network equipment so as to be not overlapped in the time domain, so that the implementation complexity of the terminal can be reduced, and the resources of the terminal can be saved.
Optionally, when the first configuration authorized resource and the second configuration authorized resource have an overlapping portion in a time domain, any method provided by the embodiment of the foregoing scenario may be adopted, and in a transmission period of a target configuration authorized resource where the overlapping portion is located, the target configuration authorized resource is used for uplink transmission, where the target configuration authorized resource is the first configuration authorized resource or the second configuration authorized resource. For example, in the fourth mode, the uplink resource configuration method provided above further includes: the network equipment sends indication information to the terminal, wherein the indication information is used for indicating the target configuration authorized resource or the uplink carrier where the target configuration authorized resource is located. Specifically, reference is made to the description in the above fourth mode, and details are not repeated here.
It can be seen that, in the above embodiment, when there are configuration grant resources on both uplink carriers, the terminal may perform uplink transmission only using the configuration grant resources on one uplink carrier at any time, that is, only using one PUSCH to perform uplink transmission at any time, so that the terminal reduces the problem of communication quality degradation caused by insufficient uplink transmission power under the condition that the uplink transmission power is limited.
When both the two uplink carriers have the configured grant resources and the configured grant resources are activated, the terminal may also cause a problem of reduced communication efficiency due to an uncertainty caused by a hybrid automatic repeat request (HARQ).
NR does not support non-adaptive retransmissions and the granted resources are configured only for new transmissions, i.e. the first transmission of data. If the HARQ process fails to transmit by using the configured grant resource, the network device has not yet had time to schedule retransmission for the HARQ process, that is, a new configured grant resource is reached, and the terminal performs new transmission on the newly reached configured grant resource and clears the HARQ buffer (buffer), so that the network device cannot schedule retransmission for the data that has failed to transmit. Therefore, a configured grant timer (configured grant timer) is introduced, which is a timer configured or started for each HARQ (per HARQ) process. When data transmission is performed by using the configuration authorized resource or the uplink resource scrambled by using a configuration scheduling RNTI (CS-RNTI), starting a configuration authorized timer corresponding to a corresponding HARQ process, and during the running period of the timer, the terminal does not use the configuration authorized resource for new transmission of the HARQ process.
In a scenario where the SUL is configured, one hybrid automatic repeat request (HARQ) process may be used for data transmission on the serving SUL carrier and the non-SUL carrier. When the transmission period of the configured grant resource is reached after the configured grant resource is configured and activated for use, the corresponding HARQ process number may be calculated according to the following formula:
HARQ Process ID＝[floor(CURRENT_symbol/periodicity)]modulo numberOfConfGrant-Processes；
wherein, the HARQ Process ID represents the HARQ Process number; floor () means rounding down the data in parentheses; modulo represents a modulo operation; CURRENT _ symbol represents the identification in the time domain of the first symbol (symbol) of the currently arriving configuration granted resource; the period represents the period of configuring the authorized resource; the numberofconfiggrant-Processes indicates the number of HARQ Processes that can transmit using the configured grant resources. The period and the numberofgrant-Processes may be configured through RRC signaling, for example, when the RRC signaling is used to configure the grant resources, the period for configuring the grant resources and the number of HARQ Processes that may use the configured grant resources for transmission are configured.
Since different carriers are not distinguished when calculating the HARQ process number, when two uplink carriers are configured, for example, in an SUL scenario, the same HARQ process number may be calculated for the resource configuration authorization on the different uplink carriers. Therefore, after the configuration authorization resource on one uplink carrier is newly transmitted and the configuration authorization timer is started, if the HARQ process numbers calculated for the configuration authorization resources on the two uplink carriers are the same, the configuration authorization resources on the two uplink carriers cannot be used for data transmission during the operation of the timer, so that the resource utilization rate is reduced and the communication efficiency is reduced.
For example, please refer to fig. 12, which is a schematic diagram illustrating a grant configuration timer limiting grant resources configured on two carriers for new transmissions according to an embodiment of the present application. In the present embodiment, the two carriers are exemplified by a non-SUL carrier and a SUL carrier, respectively. The new transmission is performed on the authorized resources configured on the non-SUL carrier, and the authorized timer configured is started, and since the HARQ process numbers (HARQ IDs) calculated for the authorized resources configured on the two carriers are both 0, during the running period of the timer, the authorized resources configured on the two carriers cannot be used for data transmission, which will cause a decrease in resource utilization and a decrease in communication efficiency.
In view of the above problems, in the embodiments of the present application, the configuration authorization resources on different carriers are associated to different HARQ processes or HARQ process sets, for example, the configuration authorization resources on the SUL carrier and the non-SUL carrier in the SUL scenario are associated to different HARQ processes or HARQ process sets, so that when the configuration authorization timer of one HARQ process is started, another HARQ process is not affected, and data transmission can still be performed, thereby improving communication efficiency and increasing resource utilization.
In one implementation, HARQ process numbers corresponding to the configuration grant resources on different uplink carriers are calculated by using different formulas. The following description is made with reference to fig. 13, which is a schematic diagram of another usage method of uplink resources provided in an embodiment of the present application. As shown in fig. 13, the method includes the steps of:
s131: the network equipment generates first configuration information and second configuration information, wherein the first configuration information is used for configuring first configuration authorization resources on a first uplink carrier for the terminal, and the second configuration information is used for configuring second configuration authorization resources on a second uplink carrier for the terminal;
s132: and the network equipment sends the first configuration information and the second configuration information to the terminal.
The terminal receives the first configuration information and the second configuration information.
S133: when the first configuration authorized resource is used, the terminal calculates a first HARQ (hybrid automatic repeat request) number corresponding to the first configuration authorized resource by using a first formula; and when the second configuration authorized resource is used, the terminal calculates a second HARQ process number corresponding to the second configuration authorized resource by using a second formula, wherein the first formula is different from the second formula.
S134: the terminal performs uplink transmission, that is, sends uplink information, and the description of the uplink information is the same as that in the above embodiment and is not described again here.
For example, after the HARQ process corresponding to the first HARQ process number uses the first configuration grant resource for uplink transmission, the first configuration grant timer is started. The first configuration authorization timer is used for limiting the initial transmission of data on the HARQ process corresponding to the first HARQ process number. When the second configuration authorized resource can be used and there is uplink data to be transmitted, the terminal may perform uplink transmission on the HARQ process corresponding to the second HARQ process number by using the second configuration authorized resource. Thereafter, the terminal may start a second configured grant timer for the second HARQ process. The second configuration authorization timer is used for limiting the initial transmission of the data on the HARQ process corresponding to the second HARQ process number.
As such, the configured grant resources on different carriers may be mapped to different HARQ processes or sets of HARQ processes. Therefore, the configuration authorization timer corresponding to the configuration authorization resource on one carrier is started, and in the running period of the configuration authorization timer, the configuration authorization resource on another carrier with different HARQ process numbers can be used for newly transmitting data, so that the communication efficiency and the resource utilization rate are improved.
Alternatively, the HARQ process numbers calculated by the configuration grant resources on the two uplink carriers may be made different by an offset (offset). That is, there is an offset value between the first and second equations. For example, the first formula and the second formula are respectively as follows:
HARQ Process ID＝[floor(CURRENT_symbol/periodicity)]modulo numberOfConfGrant-Processes；(1)
HARQ Process ID＝[floor(CURRENT_symbol/periodicity)]modulo numberOfConfGrant-Processes+harq_offset；(2)
here, the harq _ offset represents an offset value, and the meaning of other parameters is the same as that described above and is not described herein again.
The offset value is equal to the numberOfConfGrant-Processes, i.e., the number of HARQ Processes that can transmit using the allocated grant resources; the configuration granted resource may refer to a first configuration granted resource or a second configuration granted resource. The numberofconfiggrant-Processes may be configured to the terminal when the network device sends a configuration message of configuration authorization to the terminal, that is, the parameter is carried in the configuration message of configuration authorization. Furthermore, the parameters may also be configured by separate signaling. The configuration message of the configuration grant may be an RRC message for configuring a function of the configuration grant, such as configuring SPS or GF. numberofconfiggrant-Processes indicates the number of HARQ Processes that can transmit using the configured grant resources, for example, when numberofconfiggrant-Processes =1, HARQ process 0 can transmit using the configured grant resources; when numofconfiggrant-Processes =2, HARQ process 0, 1 may transmit with the configured grant resources.
When calculating the HARQ process number according to the above formula, the allocated grant resource on one carrier may correspond to multiple HARQ processes, i.e. a HARQ process set. Depending on how many the numberOfConfGrant-Processes are configured. When the numberofconfiggrant-Processes is configured to be multiple, the configured grant resources on one carrier may correspond to multiple HARQ Processes, i.e., a HARQ process set.
In addition, the network device may configure, for the first configured granted resource and the second configured granted resource, the number of HARQ processes that may utilize the first configured granted resource and the second configured granted resource for transmission, respectively. The HARQ _ offset in the above formula is the number of HARQ processes that can transmit using the first configured grant resource or the number of HARQ processes that can transmit using the second configured grant resource.
Optionally, the harq _ offset may be a parameter configured by the network device to the terminal, where the parameter refers to a parameter independent of the numberofconfiggrant-Processes.
Taking the scenario with the SUL configured as an example, when the authorized resources configured on the non-SUL carrier arrive, the HARQ process number may be calculated by using the existing formula (1). When the configuration authorization resource on the SUL carrier arrives, an offset may be added on the basis of the HARQ process number calculated by using the existing formula, that is, the HARQ process number is calculated by using the above formula (2).
Also taking fig. 12 as an example, assuming that the parameter number of offgrant-Processes in the configuration of the configuration grants on the two uplink carriers is equal to 1, the HARQ process number calculated according to the formula (1) is 0, and the HARQ process number calculated according to the formula (2) is 1, as shown in the block of the HARQ process number in the figure. The HARQ processes associated with the grant resources configured on the two uplink carriers are respectively 0 and 1. Therefore, after one uplink carrier, for example, a non-SUL carrier, performs new transmission by using the configuration grant resource, the configuration grant timer associated with the HARQ process 0 is started, and when the timer runs, the configuration grant resource on another uplink carrier, for example, a SUL carrier, is not affected for the new transmission of the HARQ process 1.
The first configuration information and the second configuration information in this embodiment are the same as those described in the above embodiment, and are not described again here. In addition, this embodiment may be combined with the above embodiment, so that when there are configuration authorization resources on both uplink carriers, the terminal may perform uplink transmission on only one PUSCH at any time, thereby reducing the problem of communication quality degradation caused by insufficient uplink transmission power under the condition that the uplink transmission power is limited; meanwhile, the problem that when the configuration authorization resource is used for newly transmitting data on one uplink carrier, the configuration authorization timer associated with the configuration authorization resource runs to ensure that the configuration authorization resources on the two uplink carriers cannot be used for newly transmitting the data is solved, so that the communication efficiency and the resource utilization rate are improved.
In an LTE communication system, SPS resources are only configured on a primary serving cell (PCell). The terminal can know the power adjustment of the SPS resource on the PCell according to a Transmit Power Control (TPC) RNTI, i.e., TPC-RNTI and a TPC Index, i.e., TPC-Index.
For example, in the LTE communication system, in order to save PDCCH resources, SPS group power control of the terminal may be implemented through tpc-RNTI. The network equipment sends out the power control information of a plurality of terminals through a power control command and scrambles by utilizing tpc-RNTI. And the terminal searches the power control command in the public search area by utilizing the tpc-RNTI and searches the power control information of the terminal by utilizing the tpc-Index. the tpc-RNTI and tpc-Index can be configured to the terminal by the network device through an RRC message. Fig. 14 is a schematic diagram of a power control command for power control of an SPS group in the prior art. Suppose that the network device configures the same TPC-RNTI for N terminals through the RRC command, and configures different TPC-indexes for each terminal, so as to indicate which TPC information in the power control command is used for adjusting the transmission power of the terminal on the SPS resource.
Unlike LTE, in NR, the configured grant resource may be configured not only on the PCell but also on a secondary serving cell (SCell), and the configuration is per BWP, that is, a set of configured grant resources may be configured on each BWP. In the SUL scenario, the grant resources are also configured on the SUL carrier and the non-SUL carrier. At this time, only through TPC-RNTI and TPC-Index, the terminal cannot determine that a received transmission power control command (TPC command) is used to adjust the transmission power of the configuration authorization resource in which cell/which carrier, which causes uncertainty of the transmission power of the terminal to the uplink resource, and further causes communication quality degradation.
In view of the above problems, embodiments of the present application further provide a method for using uplink resources, or further provide a method for controlling power. In the method, the network equipment configures scrambling information and a power control index corresponding to the power control information scrambled by the scrambling information to the terminal, and also configures the association relationship between the scrambling information or the power control index and the frequency resource. The frequency resource may be an uplink carrier or BWP, and the configuration grant resource is configured on the frequency resource. In this way, the terminal may determine the power control information for the frequency resource in the power control command according to the scrambling information and/or the power control index, so as to control the transmission power of the configuration grant resource on the frequency resource according to the power control information. Therefore, the terminal definitely configures the transmitting power of the authorized resource, and further improves the communication quality. The present embodiment can be combined with any of the above embodiments to further achieve the technical effects of any of the above embodiments.
Please refer to fig. 15, which is a schematic diagram of a power control method or a method for using uplink resources according to an embodiment of the present application. As shown in fig. 15, the method includes the steps of:
s151: the network equipment sends configuration information to the terminal, wherein the configuration information is used for configuring scrambling information and a TPC index corresponding to the TPC information scrambled by the scrambling information, and is also used for configuring the association relationship between the TPC index and a frequency resource, and the frequency resource is configured with a configuration authorization resource; among them, transmission Power Control (TPC) may be simply referred to as power control.
After the terminal receives the configuration information, the TPC command may be descrambled using the configuration information.
S152: the network device scrambles the TPC commands with the scrambling information.
S153: the network device sends the scrambled TPC command to the terminal. The terminal receives the TPC command.
S154: and the terminal descrambles the TPC command by using the scrambling information and determines the TPC information used for the frequency resource in the TPC command according to the configuration information, wherein the TPC information used for the frequency resource is the TPC information corresponding to (or indicated by) the TPC index associated with the frequency resource.
S155: and the terminal controls the transmitting power of the configuration authorization resource on the frequency resource according to the power control information. Then, S156 is executed, i.e., the allocated authorized resource is used for uplink transmission, i.e., uplink information is sent. The uplink information is the same as the description of the above embodiment, and is not described again here.
The above association relationship may also be referred to as a correspondence relationship. The above TPC information may be understood as a TPC sub-command in the TPC command, the TPC sub-command corresponding to or being associated with one frequency resource. The scrambling information may be TPC-RNTI, for example, TPC-CS-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, or the like, and RNTI for adjusting power control. The TPC Index is, for example, TPC-Index. The above frequency resource may be an uplink carrier or an uplink BWP. The above-mentioned configuration authorization resource may be a GF resource or an SPS resource as described in the above embodiments. The above configuration information may be carried through RRC signaling.
In one implementation, when the network device performs TPC configuration for the terminal, it specifies which uplink carrier of which serving cell of the terminal is adjusted by the TPC index or the power of the configured grant resource on the uplink BWP. At this time, the network device configures one piece of scrambling information for one terminal, and the scrambling information of different terminals may be the same or different. The terminals with the same scrambling information form a group, and the network equipment can control the transmission power of the configuration authorized resource of the terminals in the group through TPC commands. In addition, the network device configures a TPC index for the terminal, where the configured TPC index may be one or more according to the number of frequency resources, and each TPC index is associated with (or corresponds to) a frequency resource (e.g., an uplink carrier or an uplink BWP) of one cell.
At this time, the scrambling information configured by the configuration information is one, for example, one tpc-RNTI. The TPC information for the grant resources allocated on the frequency resources (uplink carrier or uplink BWP) of different serving cells of the terminal may be placed in a TPC command, for example, in a DCI, and sent to the terminal. The network device may perform TPC configuration for the terminal through RRC signaling, that is, the RRC signaling carries the above configuration information, where the configuration information includes one piece of scrambling information and at least one TPC index, and each TPC index corresponds to or indicates one piece of TPC information scrambled by the scrambling information. The configuration information is further used to configure an association relationship between the TPC index and the frequency resource, for example, for each TPC index, the configuration information further includes information of the frequency resource associated with the TPC index, and the information of the frequency resource is used to indicate the frequency resource, for example, an identifier or an index of the frequency resource.
For example, the following steps are carried out: it is assumed that the PCell of the terminal 1 is configured with the SUL, and the configuration grant resources, such as the GF resources, are configured on the SUL carrier and the non-SUL carrier, and the SCell 1 of the terminal 1 is not configured with the SUL, and the configuration grant resources, such as the SPS resources, are configured. When the network device performs TPC configuration for the terminal through RRC signaling, the TPC configuration information includes: one tpc-RNTI, tpc-Index 1 associated to the SUL carrier of the PCell of the terminal, tpc-Index 2 associated to the non-SUL carrier of the PCell of the terminal, tpc-Index 3 associated to the SCell 1 of the terminal.
Please refer to fig. 16, which is a diagram illustrating a TPC command according to an embodiment of the present invention. When the terminal 1 receives the TPC command scrambled with TPC-RNTI, the terminal 1 will: adjusting the transmitting power of the authorized resource configured on the SUL carrier of the PCell by using TPC information x corresponding to the TPC-Index 1; adjusting the transmitting power of the authorized resource configured on the non-SUL carrier of the PCell by using TPC information y corresponding to TPC-Index 2; and adjusting the transmission power of the configured grant resources on the SCell 1 uplink carrier by using TPC information z corresponding to the TPC-Index 3.
The other terminals may use the same TPC command format as terminal 1 or may use different TPC command formats. Further, TPC information scrambled with the same scrambling information as that of terminal 1 may be put in one TPC command with the TPC information of terminal 1, for example, TPC information n of terminal m shown in fig. 16.
In the above method, by associating TPC-Index with a specific frequency resource, after receiving the TPC, the terminal may determine which frequency resource is to be adjusted to configure the power of the grant resource. Thus, it is possible to reduce the problem caused by the uncertainty of the terminal with respect to the target to which the TPC command is directed, and improve the communication quality.
In another implementation, the network device configures the GF resources and SPS resources separately. Configuring scrambling information for GF resources, and configuring at least one TPC index, wherein each TPC index is associated with one frequency resource; for the SPS resource, another scrambling information is configured, and at least one TPC index is configured, each TPC index being associated with one frequency resource.
At this time, the above configuration information may include: the first scrambling information and the second scrambling information are respectively used for scrambling TPC information for carrying out power control on the GF resources and TPC information for carrying out power control on the SPS resources; power control indexes corresponding to the power control information scrambled by the first scrambling information; power control indexes corresponding to the power control information scrambled by the second scrambling information; and information of frequency resources corresponding to each power control index. Wherein, if at least one power control information scrambled by the first scrambling information is used, the corresponding power control index is at least one; if the power control information scrambled by the second scrambling information is at least one, the corresponding power control index is at least one. The first scrambling information, the power control index corresponding to the power control information scrambled by the first scrambling information, and the information of the corresponding frequency resource may be located in a configuration message, for example, an RRC message; the second scrambling information, the power control index corresponding to the power control information scrambled by the second scrambling information, and the information of the corresponding frequency resource may be located in another configuration message, for example, another RRC message. I.e. TPC configuration may be performed for each of the GF resources and the SPS resources. Alternatively, these information may be located in the same configuration message, for example, the same RRC message, that is, the TPC configuration may be performed on the GF resource and the SPS resource simultaneously.
TPC information for GF resources on frequency resources of different serving cells of a terminal may be placed in a TPC command, e.g., in a DCI; the TPC information for SPS resources on frequency resources of different serving cells for the terminal may be placed in another TPC command, such as in another DCI. The two TPC commands are scrambled with different scrambling information. For example, the network device may configure tpc-RNTI a for the terminal for the GF resource through RRC signaling, where the RRC signaling carries at least one tpc-Index associated with the tpc-RNTI a, and each tpc-Index is associated with a frequency resource of one serving cell, to which the GF resource is configured; and the network equipment configures tpc-RNTI B for the terminal aiming at the SPS resource through RRC signaling, at least one tpc-Index associated with the tpc-RNTI B is carried in the RRC message, and each tpc-Index is associated with one frequency resource configured with the SPS resource of one service cell.
If the SUL is configured on the PCell of the terminal 1, and GF resources are configured on the SUL carrier and non-SUL carrier, the SCell 1 of the terminal 1 is not configured with the SUL, and SPS resources are configured. When the network device performs TPC configuration for the GF resource of the terminal through RRC signaling 1, the RRC signaling 1 includes: tpc-RNTI A, tpc-Index 1 associated to SUL carrier of PCell of the terminal, tpc-Index 2 associated to non-SUL carrier of PCell of the terminal. When the network device performs TPC configuration for the SPS resource of the terminal through the RRC signaling 2, the RRC signaling 2 includes: tpc-RNTI B, tpc-Index 3 associated to SCell 1 of the terminal. The RRC signaling 1 and the RRC signaling 2 may be the same message or different messages.
Please refer to fig. 17, which is a diagram illustrating another TPC command according to an embodiment of the present application. When terminal 1 receives TPC command 1 scrambled with TPC-RNTI a, terminal 1 will: adjusting the transmitting power of GF resources on SUL carrier waves of the PCell by TPC information x corresponding to TPC-Index 1; and adjusting the transmitting power of the GF resources on the non-SUL carrier of the PCell by using TPC information y corresponding to the TPC-Index 2. When terminal 1 receives TPC command 2 scrambled with TPC-RNTI B, terminal 1 will adjust the transmit power of SPS resources on SCell 1 with TPC information 2 corresponding to TPC-Index 3.
The other terminals may use the same TPC command format as terminal 1 or may use different TPC command formats. Further, TPC information scrambled with the same scrambling information as that of terminal 1 may be placed in one TPC command with TPC information of terminal 1, such as TPC information n and TPC information s of terminal m shown in fig. 17.
In the above method, by associating TPC-Index with a specific frequency resource, after receiving the TPC, the terminal may determine which frequency resource is to be adjusted to configure the power of the grant resource. Thus, problems caused by uncertainty of a terminal with respect to an object to which a TPC command is directed can be reduced, and communication quality can be improved. In addition, the kind of the authorized resource can be distinguished by scrambling information.
In another implementation, the network device performs TPC configuration on the authorized resources configured on the SUL carrier and the non-SUL carrier, respectively; configuring scrambling information for all SUL carriers of a terminal, and configuring at least one TPC index, wherein each TPC index is associated with a frequency resource, such as an SUL carrier or a BWP on the SUL carrier; configuring another scrambling information for all non-SUL carriers of the terminal and uplink carriers of cells not configured with SUL, and configuring at least one TPC index, wherein each TPC index is associated with a frequency resource, such as one non-SUL carrier, one uplink carrier of a cell not configured with SUL, one BWP on a non-SUL carrier, or one BWP on an uplink carrier of a cell not configured with SUL.
At this time, the above configuration information may include: the first scrambling information and the second scrambling information are respectively used for scrambling TPC information for carrying out power control on the configuration authorization resource on the first carrier and TPC information for carrying out power control on the configuration authorization resource on the second carrier, wherein the first carrier is an SUL carrier, and the second carrier is a non-SUL carrier or an uplink carrier of a cell without configuration SUL; a power control index corresponding to the power control information scrambled by the first scrambling information; a power control index corresponding to the power control information scrambled by the second scrambling information; and information of frequency resources corresponding to each power control index. Wherein, if at least one power control information scrambled by the first scrambling information is used, the corresponding power control index is at least one; if the power control information scrambled by the second scrambling information is at least one, the corresponding power control index is at least one. The first scrambling information, the power control index corresponding to the power control information scrambled by the first scrambling information, and the information of the corresponding frequency resource may be located in a configuration message, for example, an RRC message; the second scrambling information, the power control index corresponding to the power control information scrambled by the second scrambling information, and the information of the corresponding frequency resource may be located in another configuration message, for example, another RRC message. That is, TPC configuration may be performed on the SUL carriers and uplink carriers other than the SUL carriers (including non-SUL carriers and uplink carriers of cells not configured with SUL). Alternatively, the information may be located in the same configuration message, for example, the same RRC message, that is, the TPC configuration may be performed on the SUL carrier and the uplink carriers other than the SUL carrier at the same time.
TPC information of authorized resources configured on SUL carriers of different service cells of a terminal is put in a TPC command, for example, put in a DCI; the TPC information of the authorized resource configured on the non-SUL carrier of different service cells of the terminal and the uplink carrier of the service cell without the SUL is placed in another TPC command, for example, in another DCI. The two TPC commands are scrambled with different scrambling information. For example, the network device configures tpc-RNTI a for the terminal by RRC signaling, and carries at least one tpc-Index corresponding to tpc-RNTI a in the RRC signaling, where each tpc-Index is associated with one frequency resource, for example, one SUL carrier of the serving cell configured with the SUL or one BWP on the SUL carrier of the serving cell configured with the SUL. And the network device configures tpc-RNTI B for the terminal through RRC signaling, and the RRC signaling carries at least one tpc-Index corresponding to tpc-RNTI B, where each tpc-Index is associated with a frequency resource, for example, a non-SUL carrier of a serving cell configured with SUL, an uplink carrier of a serving cell not configured with SUL, a BWP on a non-SUL carrier of a serving cell configured with SUL, or a BWP on an uplink carrier of a serving cell not configured with SUL.
For example, the following steps are carried out: assume that the PCell of the terminal 1 is configured with the SUL, and GF resources are configured on the SUL carrier and the non-SUL carrier, and the SCell 1 of the terminal 1 is not configured with the SUL and SPS resources are configured. When the network device performs TPC configuration on the configuration authorization resource on the SUL carrier of the terminal through RRC signaling 1, the RRC signaling 1 includes: tpc-RNTI A, tpc-Index 1 associated to SUL carrier of PCell of the terminal. When the network device performs TPC configuration on the non-SUL carrier of the terminal and the configuration authorization resource on the uplink carrier of the cell without the SUL through the RRC signaling 2, the RRC signaling 2 includes: tpc-RNTI B, tpc-Index 2 associated to non-SUL carrier of PCell of the terminal, and tpc-Index 3 associated to uplink carrier of SCell 1 of the terminal.
Please refer to fig. 18, which is a schematic diagram illustrating another TPC command according to an embodiment of the present application. When terminal 1 receives TPC command 1 scrambled with TPC-RNTI a, terminal 1 will: adjusting the transmitting power of the authorized resources configured on the SUL carrier of the PCell by using TPC information x corresponding to the TPC-Index 1; when the terminal 1 receives the TPC command 2 scrambled by TPC-RNTI B, the TPC information 1 corresponding to TPC-Index 2 is used for adjusting the transmitting power of the authorized resource configured on the non-SUL carrier of the PCell. Terminal 1 will adjust the transmit power of the configured grant resource on SCell 1 with TPC information 2 corresponding to TPC _ Index 3.
The other terminals may use the same TPC command format as terminal 1 or may use different TPC command formats. Further, TPC information scrambled with the same scrambling information as that of terminal 1 may be placed in one TPC command with TPC information of terminal 1, such as TPC information n and TPC information s of terminal m shown in fig. 18.
In the above method, by associating TPC-Index with a specific frequency resource, after receiving the TPC, the terminal may determine which frequency resource is to be adjusted to configure the power of the grant resource. Thus, it is possible to reduce the problem caused by the uncertainty of the terminal with respect to the target to which the TPC command is directed, and improve the communication quality. In addition, the configuration authorization resources of the SUL carrier and other uplink carriers can be distinguished through scrambling information.
Another option in this embodiment is: and the non-SUL carrier is also distinguished from the uplink carrier of the cell without the SUL, and different scrambling information is configured. For example, the network device configures tpc-RNTI a for the terminal through RRC signaling, where the RRC signaling carries at least one tpc-Index corresponding to the tpc-RNTI a, and each tpc-Index is associated with one SUL carrier of the SUL-configured serving cell, or is associated with one BWP of the SUL carrier of the SUL-configured serving cell. The network equipment configures tpc-RNTI B aiming at the non-SUL carrier through RRC signaling, at least one tpc-Index corresponding to the tpc-RNTI B is carried in the RRC signaling, and each tpc-Index is associated with one non-SUL carrier of the service cell configured with the SUL or associated with one BWP of the non-SUL carrier of the service cell configured with the SUL. The network equipment configures tpc-RNTI C for the uplink carrier of the serving cell without the SUL through RRC signaling, wherein the RRC signaling carries at least one tpc-Index corresponding to the tpc-RNTI C, and each tpc-Index is associated with one uplink carrier of the serving cell without the SUL or associated with one BWP of the uplink carrier of the serving cell without the SUL. The RRC signaling configuring the tpc-RNTI A, the tpc-RNTI B and the tpc-RNTI C can be the same message or different messages.
At this time, the configuration information may include: the system comprises a plurality of scrambling messages and a plurality of sending module, wherein the scrambling messages are used for scrambling TPC information for performing power control on configuration authorization resources of a plurality of types of uplink carriers; using TPC index corresponding to TPC information scrambled by each scrambling information; and information of a frequency resource corresponding to each TPC index. The types of the uplink carriers comprise a first type and a second type, wherein the first type is an SUL carrier, and the second type is a non-SUL carrier or an uplink carrier of a cell without an SUL; or the types of the uplink carriers include a first type, a second type and a third type, wherein the first type is an SUL carrier, the second type is a non-SUL carrier, and the third type is an uplink carrier of a cell where the SUL is not configured.
The above manners of TPC configuration for GF resources and SPS resources respectively and TPC configuration for different uplink carrier types respectively may be combined. At this time, an independent scrambling message, such as tpc-RNTI, may be configured for a type of configuration grant resource of a type of uplink carrier. At this time, the scrambling information may distinguish the type of the grant resource in addition to the uplink carrier.
At this time, the configuration information includes a plurality of scrambling information, each scrambling information is used for scrambling TPC information for performing power control on a configuration authorization resource of a type of uplink carrier; using TPC index corresponding to TPC information scrambled by each scrambling information; and information of a frequency resource corresponding to each TPC index. The types of the uplink carriers comprise a first type and a second type, wherein the first type is an SUL carrier, and the second type is a non-SUL carrier or an uplink carrier of a cell without an SUL; the types of the configuration granted resources include GF resources and SPS resources. Or the types of the uplink carriers comprise a first type, a second type and a third type, wherein the first type is an SUL carrier, the second type is a non-SUL carrier, and the third type is an uplink carrier of a cell without an SUL; the types of the configuration granted resources include GF resources and SPS resources.
In yet another implementation, the network device indicates, through physical layer signaling, for which type of uplink carrier the current TPC command is used for power control of the configuration grant resource. The TPC command is, for example, DCI, where the DCI includes indication information for indicating an uplink carrier type for which the current TPC command is used, and the indication information may be referred to as carrier indication or carrier index (carrier index). The types of the uplink carriers may include a first type and a second type, where the first type is an SUL carrier, and the second type is a non-SUL carrier or an uplink carrier of a cell not configured with SUL; or, the types of the uplink carriers may include a first type, a second type, and a third type, where the first type is an SUL carrier, the second type is a non-SUL carrier, and the third type is an uplink carrier of a cell where an SUL is not configured.
At this time, the configuration information may include one scrambling information or may include a plurality of scrambling information.
Taking a scrambling message as an example, the configuration message includes a scrambling message, a plurality of sets of TPC indexes corresponding to the TPC messages scrambled by the scrambling message, and information of frequency resources corresponding to each TPC index, where each set of TPC indexes includes at least one TPC index, and each set of TPC indexes corresponds to one type of uplink carrier. At this time, when determining the power control information for the frequency resource in the TPC command, the terminal may determine the uplink carrier type for the TPC command according to the indication information.
When the types of the uplink carriers may include a first type and a second type, and the first type is a SUL carrier, and the second type is a non-SUL carrier or an uplink carrier of a cell not configured with a SUL, TPC information for configuring an authorized resource on a SUL carrier of a different serving cell of a terminal is placed in one TPC command, for example, in one DCI. The TPC information of the authorized resource configured on the non-SUL carrier of different service cells of the terminal and the uplink carrier of the service cell not configured with SUL is put in another TPC command, for example, in another DCI. Both TPC commands are scrambled using the same TPC-RNTI. And newly adding a carrier index in the DCI, and indicating whether the TPC command adjusts the power of the authorized resource configured on the SUL carrier or adjusts the power of the authorized resource configured on the non-SUL carrier or the uplink carrier of the service cell without the SUL. For example: and the carrier index is 1, the TPC command is indicated to be a TPC command for adjusting the SUL carrier, the carrier index is 0, and the TPC command is indicated to be a TPC command for adjusting a non-SUL carrier or an uplink carrier of a service cell without SUL. The values and meanings of the carrier indexes are only given as examples, and are not limited.
For example, the network device configures one tpc-RNTI for the terminal through RRC signaling, where the RRC signaling carries two sets of tpc-indexes corresponding to the tpc-RNTI, and each set of tpc-indexes includes at least one tpc-Index. Wherein each tpc-Index of a set of tpc-indexes is associated with one SUL carrier of the SUL-configured serving cell or one BWP of the SUL carrier of the SUL-configured serving cell. Each tpc-Index in the other set of tpc-indexes is associated with one non-SUL carrier of the serving cell with the SUL configured or one uplink carrier of the serving cell without the SUL configured, or is associated with one BWP of the non-SUL carrier of the serving cell with the SUL configured or one BWP of the uplink carrier of the serving cell without the SUL configured.
For example, the following steps are carried out: suppose that the PCell of the terminal 1 is configured with the SUL, and GF resources are configured on the SUL carrier and the non-SUL carrier, and the SCell 1 of the terminal is not configured with the SUL and SPS resources are configured. When the network device performs TPC configuration for the configuration authorization resource on the SUL carrier of the terminal through RRC signaling, the RRC signaling includes: tpc-RNTI A and two groups of tpc-indexes; one set of tpc-indexes includes: tpc-Index 1 of the SUL carrier associated to the PCell of the terminal; another set of tpc-indexes includes: tpc _ Index 2 associated to the non-SUL carrier of the PCell of the terminal, tpc _ Index 3 associated to the SCell 1 of the terminal.
Please refer to fig. 19, which is a diagram illustrating another TPC command according to an embodiment of the present application. When terminal 1 receives TPC command 1 scrambled with TPC-RNTI and TPC command 1 includes a carrier index (carrier index) indicating a SUL carrier, terminal 1 will: adjusting the transmitting power of the authorized resource configured on the SUL carrier of the PCell by using TPC information x corresponding to the TPC-Index 1; when the terminal 1 receives a TPC command 2 scrambled by TPC-RNTI and the carrier Index included in the TPC command 2 indicates a non-SUL carrier or an uplink carrier of an UNSUL cell, TPC information 1 corresponding to TPC-Index 2 is used for adjusting the transmitting power of the authorized resource configured on the non-SUL carrier of the PCell. Terminal 1 will adjust the transmit power of the configured grant resource on SCell 1 with TPC information 2 corresponding to TPC-Index 3.
The types of the uplink carriers may include a first type, a second type, and a third type, where the first type is an SUL carrier, the second type is a non-SUL carrier, and the third type is an uplink carrier of a cell where an SUL is not configured. The network equipment configures a tpc-RNTI for the terminal through RRC signaling, and the RRC message carries three groups of tpc-indexes corresponding to the tpc-RNTI, wherein each tpc-Index in the first group of tpc-indexes is associated with one SUL carrier of the serving cell configured with the SUL or associated with one BWP of the SUL carrier of the serving cell configured with the SUL; each tpc-Index in the second set of tpc-indexes is associated with one non-SUL carrier of the serving cell in which the SUL is configured and one BWP of the non-SUL carrier of the serving cell in which the SUL is configured; each tpc-Index in the third set of tpc-indexes is associated with one uplink carrier of the serving cell not configured with the SUL or one BWP of the uplink carrier of the serving cell not configured with the SUL.
TPC information of authorized resources configured on SUL carriers of different service cells of a terminal is put in a TPC command. TPC information of authorized resources configured on non-SUL carriers of different service cells of the terminal is put in another TPC command. And the TPC information of the authorized resource configured on the uplink carrier of the service cell which is not configured with the SUL by the terminal is put in another TPC command. These TPC commands are scrambled using the same TPC-RNTI. And newly adding a carrier index in the DCI, and indicating that the TPC command is to adjust the power of the authorized resource configured on the SUL carrier, the non-SUL carrier or the uplink carrier of the service cell without the SUL through the carrier index. For example, the carrier index may be 0, 1, or 2, and is used to indicate that the DCI command is a TPC command for adjusting a SUL carrier, a non-SUL carrier, or an uplink carrier of a serving cell not configured with a SUL. The values and meanings of the carrier indexes are only given as examples, and are not limited.
Taking multiple pieces of scrambling information as an example, the configuration information includes first scrambling information and second scrambling information, multiple sets of TPC indexes corresponding to the TPC information scrambled by the first scrambling information, multiple sets of TPC indexes corresponding to the TPC information scrambled by the second scrambling information, and information of a frequency resource corresponding to each TPC index, where each set of TPC indexes includes at least one TPC index, and each set of TPC indexes corresponds to one type of uplink carrier. At this time, when determining the power control information for the frequency resource in the TPC command, the terminal may determine the uplink carrier type for the TPC command according to the indication information. Wherein the first scrambling information and the second scrambling information are respectively used for scrambling power control information for power control of the GF resource and power control information for power control of the SPS resource
For example, TPC configuration is performed separately for GF resources and SPS resources. For GF resources, the network device may configure tpc-RNTI a using RRC signaling 1, and configure multiple sets of tpc-indexes, where one tpc-Index in each set of tpc-indexes is associated with one carrier in one type of uplink carrier. For SPS resources, network equipment can configure tpc-RNTI B by using RRC signaling 2, and configure multiple groups of tpc-indexes, wherein one tpc-Index in each group of tpc-indexes is associated with one carrier in one type of uplink carriers. When the terminal receives a TPC command 1 scrambled by TPC-RNTI A, the terminal judges which type of uplink carrier the TPC command 1 is used for adjusting the transmitting power of the GF resources on according to the carrier Index in the TPC command 1, and then adjusts the transmitting power of the GF resources on the corresponding carrier according to the TPC-Index group associated with the type of carrier in the RRC configuration message. When receiving a TPC command 2 scrambled by TPC-RNTI B, judging which kind of SPS resource transmitting power on the uplink carrier the TPC command 2 is used for adjusting according to the carrier Index in the TPC command 2, and then adjusting the SPS transmitting power on the corresponding carrier according to the TPC-Index group associated with the kind of carrier in the RRC configuration message. RRC signaling 1 and RRC signaling 2 may be the same RRC message or different RRC messages.
In the above method, by associating TPC-Index with a specific frequency resource, after receiving the TPC command, the terminal may determine which frequency resource is to be adjusted to configure the power of the grant resource. Thus, it is possible to reduce the problem caused by the uncertainty of the terminal with respect to the target to which the TPC command is directed, and improve the communication quality. In addition, by adding the indication information to the DCI, the configuration grant resources of the SUL carrier and other uplink carriers can be distinguished.
