Description

Resource allocation method, terminal and base station
Technical Field
The present invention relates to the field of mobile communication technologies, and in particular, to a resource allocation method, a terminal, and a base station.
Background
Currently, uplink transmission based on codebook (codebook) can only support a resource set (set) of Sounding Reference Signal (SRS), and each resource set can only have one type of time behavior, such as periodic or non-periodic. While only supporting periodic or aperiodic transmissions is not the optimal operating mode for the system, the advantages and disadvantages of only supporting both periodic and aperiodic modes are analyzed as follows:
for the periodic configuration, the base station can be ensured to always obtain the uplink channel information and perform scheduling, but the flexibility is lacked, the channel information between two times of transmission is difficult to obtain accurately, and the service requirement at any time cannot be met. If the period density is increased, the power consumption of the terminal is increased, more SRS resources are occupied, and the capacity of the SRS in the network is reduced. If the period is too large, the accuracy of the channel information is affected.
For the aperiodic configuration, the method has the advantages of strong instantaneity and small overall overhead of the system, but lacks the prior Information in the previous period, and the accuracy of single measurement can present a challenge, and in addition, the signaling overhead problem of Downlink Control Information (DCI) can exist in multiple times of scheduling.
For a wider application scenario in the future, such as a higher mobile speed (e.g., 30km/h), the transmission density and frequency of the SRS are required to be higher in such a scenario. As described above, in theory, more frequent SRS transmission can help the base station to better obtain the state information of the channel, but also brings a large amount of system overhead, and increases energy consumption caused by frequent terminal transmission.
The current SRS transmission supports 4 different operating modes or uses (usages):
1) the uplink beam Management (beam Management) is mainly used for acquiring uplink channel information;
2) uplink Codebook transmission (Codebook), which is mainly used for acquiring uplink channel information and assisting uplink Codebook-based uplink data transmission;
3) uplink non-codebook transmission (non-codebook), which is mainly used for acquiring uplink channel information and assisting uplink non-codebook-based data transmission;
4) antenna switching (antenna switching) is mainly used for acquiring downlink channel information and assisting in downlink data transmission.
Each operating mode is configured according to a set of SRS resource sets, and the time behavior of each resource set is kept consistent, being only periodic, semi-persistent or non-periodic.
Limited by the design of DCI, the indication information of SRS Resource Indicator (SRI) is limited, and uplink codebook transmission and non-codebook transmission can only support a Resource set of one SRS.
In addition, the channel information acquisition of the uplink and downlink of the existing protocol is designed separately. The SRS transmission based on antenna switching (antenna switching) is mainly used to acquire downlink channel state information. The other 3 kinds of usage (usage) SRS transmissions mainly serve for uplink traffic transmission. The following operations are supported in the SRS transmission mode based on the antenna switch:
1)1T2R:
2 SRS resource sets (SRS resource sets) can be configured, each set includes 2 SRS resources, each SRS resource set is transmitted on a different symbol (symbol), and each SRS resource set includes 1 port (port).
2)2T4R
2 SRS resource sets can be configured, each set includes 2 SRS resources, which are transmitted on different symbols, and each resource includes 2 ports.
3)1T4R
For periodic transmission, 4 resources can be configured, and each resource corresponds to one port on different symbols.
4)1T1R,2T2R,4T4R
2 SRS resource sets can be configured, each set contains 1 SRS resource, and each resource corresponds to 1/2/4 ports.
The above 1T2R indicates when the terminal is configured as 1T2R (one transmission port/antenna, 2 reception ports/antennas). Where T denotes transmit and R denotes receive. In case of 2T4R, SRS transmission is as shown in fig. 1, each group includes two SRS resources, one SRS resource is configured with Port1 and Port 2(Port1, 2), and the other SRS resource is configured with Port3 and Port 4(Port3, 4).
As can be seen from the above, the prior art only supports two transmission modes, i.e. codebook and non-codebook, for uplink transmission, and each transmission mode only supports one SRS resource set configuration. Each SRS resource set configuration can only support one behavior of configuration period or aperiodic, and cannot realize transmission mode combining period and aperiodic. In addition, the existing protocol is separated into two processes for channel detection of uplink and downlink channels or acquisition of channel information, and theoretically, 2 sets of SRS need to be configured to acquire respective channel information, which results in high overhead.

The network device 12 may be a Base Station and/or a core network element, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention only takes the Base Station in the NR system as an example, but does not limit the specific type of base station.
The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.
The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.
The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.
As described in the background art, in the prior art, unexpected situations such as cell unavailability, slice access failure, or slice QoS fallback may occur after cell reselection or access of a terminal, which seriously affects user experience.
As described in the background, the prior art can only support the SRS transmission only periodically or non-periodically. And the problem of the simple supporting of periodic or aperiodic transmission can be effectively solved by combining the periodic and aperiodic SRS. As shown in fig. 3, the terminal may periodically transmit the SRS reference signal in a relatively more sparse manner, and may transmit the aperiodic SRS signal in the middle of two periodic SRS transmissions based on the DCI instruction when necessary. On the other hand, by reducing the transmission frequency of the periodic SRS, the overhead of the SRS system and the power consumption of the terminal are reduced, and the base station maintains the knowledge of the state of the UE basic channel. On the other hand, the aperiodic SRS indicated by the DCI acquires the latest channel state information when the base station needs it, so that the base station can schedule the base station based on the more accurate channel information.
Referring to fig. 4, a resource allocation method provided in an embodiment of the present invention, when applied to a base station side, includes:
step 41, the base station configures a first resource for antenna switching for the terminal, and configures or indicates a resource and/or a port available for uplink transmission in the first resource, where the first resource is at least one SRS resource or an SRS resource set.
Through the above steps, the embodiment of the present invention configures the first resource for antenna switching, so that the base station can acquire downlink channel information based on SRS transmission by antenna switching (antenna switching). In addition, the first resource further includes a resource and/or a port that can be used for uplink transmission, and can assist the base station to acquire uplink channel information and serve for transmission of uplink services, so that the first resource has multiple uses.
Specifically, the base station may configure the first resource through Radio Resource Control (RRC) signaling or a medium access control element (MAC CE), where the configuration of the first resource includes at least one of:
1) the resource type or time domain behavior of the first resource is a periodic transmission;
2) the uplink transmission is based on a codebook;
3) and the ports which can be used for uplink transmission in the first resource are configured on the same SRS resource. For example, when there are multiple ports available for uplink transmission, the ports may be configured on the same SRS resource.
Through the above configuration, the base station may perform detection, such as channel detection, according to the resource and/or port indicated by the first resource and used for uplink transmission, so as to obtain uplink channel information.
After step 41, the base station may further send a first scheduling signaling for scheduling the first uplink data transmission to the terminal, where the first scheduling signaling indicates a resource and/or a port available for the first uplink data transmission in the target first resource. Here, the first scheduling signaling may specifically be DCI. The target first resource is a resource and/or a port in a first resource used by a certain specific uplink transmission of the terminal, or the target first resource is a resource and/or a port in a first resource indicated by the first scheduling signaling (i.e., the first resource is indicated in the first scheduling signaling). The specific uplink transmission may be a predetermined uplink transmission, such as the last uplink transmission of the terminal, or other uplink transmissions. In this way, the terminal may perform uplink data transmission using resources available for uplink transmission in the first resources for antenna switching. In addition, it should be noted that, in this document, the "resource and/or port" generally refers to SRS resource and/or port.
Specifically, the port used for the first uplink data transmission may be the same as the port available for uplink transmission in the target first resource indicated by the first scheduling signaling. In addition, when the first resource configuration or the indicated ports available for uplink transmission are not on the same SRS resource (for example, the ports available for uplink transmission include port1 and port2, where port1 is on SRS resource 1 and port2 is on SRS resource 2), the first scheduling signaling may indicate only the resources available for the first uplink data transmission in the target first resources, and does not indicate a specific port.
Optionally, the base station may also configure, for the terminal, a second resource used for uplink transmission of the codebook, where the second resource is at least one SRS resource or an SRS resource set.
Specifically, the base station may configure the second resource through an RRC signaling MAC CE, where the configuration of the second resource includes at least one of:
1) a resource type or time domain behavior of the second resource is aperiodic transmission;
2) the power control parameter of the second resource is the same as the power control parameter of the first resource;
3) and the reference resource of the spatial relationship information of the second resource is a resource and/or a port which can be used for uplink transmission in the first resource.
In this way, the base station can configure the periodic first resource and the aperiodic second resource, thereby reducing the transmission frequency of the periodic SRS, reducing the SRS system overhead and the power consumption of the terminal, and maintaining the base station's knowledge of the state of the basic channel of the terminal. On the other hand, the latest channel state information can be acquired by the aperiodic SRS indicated by the DCI when the base station needs the information, so that the base station can schedule the terminal based on the more accurate channel information.
Based on the above configuration, the base station may perform sounding according to the second resource. Or, the base station performs detection or joint detection respectively according to the resources and/or ports which can be used for uplink transmission in the second resources and the first resources. Here, performing probing respectively refers to performing probing according to the second resource, and performing probing according to a resource and/or a port that can be used for uplink transmission in the first resource; performing joint probing refers to performing probing according to resources and/or ports available for uplink transmission in the second resources and the first resources. For example, joint sounding may be sounding for an SRS jointly transmitted by a terminal over multiple slots, or sounding for multiple SRSs bundled in time (bundling).
In this embodiment of the present invention, the base station may further send a second scheduling signaling (specifically, DCI) for scheduling second uplink data transmission to the terminal, where the second scheduling signaling indicates a resource and/or a port, which may be used for second uplink data transmission, in the target second resource; the target second resource is a resource and/or a port in a second resource used by a certain specific uplink transmission (such as the last uplink transmission or an agreed other uplink transmission), or the target second resource is a resource and/or a port in a second resource indicated by the second scheduling signaling (i.e., the second resource is indicated in the second scheduling signaling).
Optionally, the antenna port used for the second uplink data transmission may be the same as the port available for uplink transmission in the target second resource indicated by the second scheduling signaling. And when the second resource configuration or the indicated ports available for uplink transmission are not on the same SRS resource, the second scheduling signaling may indicate only the resources available for second uplink data transmission in the target second resource, without indicating a specific port.
Optionally, the base station may further send a third scheduling signaling for scheduling third uplink data transmission to the terminal, where the third scheduling signaling indicates a resource and/or a port that can be used for third uplink data transmission in the target third resource.
When the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal for the last uplink transmission is the first resource, the target third resource is: a resource and/or port in the first resource;
when the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal for the last uplink transmission is the second resource, the target third resource is: a resource and/or port in the second resource;
when the third scheduling signaling indicates the first resource or the second resource, the target third resource is: resources and/or ports in the first resources or the second resources indicated by the third scheduling signaling.
Here, the antenna port used for the third uplink data transmission is the same as the port available for uplink transmission in the resource indicated by the third scheduling signaling. And when the first resource or the second resource configuration or the indicated ports available for uplink transmission are not on the same resource, the third scheduling signaling only indicates the resources available for the third uplink data transmission, and does not indicate a specific port.
Optionally, the base station may further configure, for the terminal, a third resource used for antenna switching, and configure a resource and/or a port that can be used for uplink transmission in the third resource, where the third resource is at least one SRS resource or an SRS resource set.
Specifically, the base station may configure the third resource through an RRC signaling MAC CE, where the configuration of the third resource includes at least one of:
1) a resource type or time domain behavior of the third resource is transmitted aperiodically;
2) the power control parameter of the third resource is the same as the power control parameter of the first resource;
3) and the reference resource of the spatial relationship information of the third resource is a resource and/or a port which can be used for uplink transmission in the first resource.
Based on the above configuration, the base station may perform sounding according to the third resource, or the base station may perform sounding or joint sounding respectively according to a resource and/or a port that can be used for uplink transmission in the third resource and the first resource. The joint sounding may be sounding for an SRS jointly transmitted by a terminal over multiple slots, or sounding for multiple SRSs bundled in time (bundling).
In this embodiment of the present invention, the base station may further send a fourth scheduling signaling for scheduling fourth uplink data transmission to the terminal, where the fourth scheduling signaling indicates a resource and/or a port that can be used for the fourth uplink data transmission in the target fourth resource. Here, the target fourth resource is a resource and/or a port in a third resource used by a specific uplink transmission (for example, the last uplink transmission, or another agreed uplink transmission) of the terminal at a time, or the target fourth resource is a resource and/or a port in the third resource indicated by the fourth scheduling signaling.
Optionally, an antenna port used for the fourth uplink data transmission is the same as a port available for uplink transmission in the target fourth resource indicated by the fourth scheduling signaling.
In this embodiment of the present invention, the base station may further send a fifth scheduling signaling for scheduling fifth uplink data transmission to the terminal, where the fifth scheduling signaling indicates a resource and/or a port that can be used for the fifth uplink data transmission in the target fifth resource;
when the fifth scheduling signaling does not indicate the first resource or the third resource, if the resource used by a certain specific uplink transmission (such as the latest uplink transmission or other agreed uplink transmissions) of the terminal is the first resource, the target fifth resource is: a resource and/or port in the first resource;
when the fifth scheduling signaling does not indicate the first resource or the third resource, if the resource used by a certain uplink transmission (such as the last uplink transmission or other agreed uplink transmissions) of the terminal is the third resource, the target fifth resource is: a resource and/or port of a resource available for uplink transmission in the third resource;
when the fifth scheduling signaling indicates the first resource or the third resource, the target fifth resource is: resources and/or ports in the first resource or the third resource indicated by the fifth scheduling signaling.
Optionally, an antenna port used for the fifth uplink data transmission is the same as a port available for uplink transmission in the transmission resource indicated by the fifth scheduling signaling. In addition, when the first resource or the third resource configuration or the indicated port available for uplink transmission is not on the same resource, the fifth scheduling signaling indicates only the resource available for fifth uplink data transmission, and does not indicate a specific port.
As can be seen from the above description, the embodiments of the present invention utilize SRS transmission, which not only enables the base station to obtain downlink channel information, but also assists the base station to obtain uplink channel information. In addition, the embodiment of the invention can realize the joint transmission of the periodic and non-periodic SRS under the condition of not increasing the SRS resource, reduce the SRS transmission resource and simultaneously support a better acquisition mode of the channel information which is combined with the period and the non-period. In addition, the embodiment of the present invention may also multiplex the related indication of the existing DCI without increasing the SRS resource set.
The method of the embodiment of the present invention is further received from the terminal side as follows.
As shown in fig. 5, the resource allocation method according to the embodiment of the present invention, when applied to the terminal side, includes:
step 51, a terminal receives first configuration information sent by a base station, where the first configuration information is used to configure a first resource used for antenna switching and a resource and/or a port that can be used for uplink transmission in the first resource, and the first resource is at least one SRS resource or an SRS resource set.
Through the above steps, the base station can obtain downlink channel information based on the SRS transmitted by the terminal and based on antenna switching by configuring the first resource whose purpose is antenna switching. In addition, the first resource further includes a resource and/or a port that can be used for uplink transmission, and can assist the base station to acquire uplink channel information and serve for transmission of uplink services, so that the first resource has multiple uses.
Specifically, the terminal may receive the configuration of the first resource sent by the base station through RRC signaling or MAC CE, where the configuration of the first resource includes at least one of the following:
1) the resource type or time domain behavior of the first resource is a periodic transmission;
2) the uplink transmission is based on a codebook;
3) and the ports which can be used for uplink transmission in the first resource are configured on the same SRS resource. For example, when there are multiple ports available for uplink transmission, the ports may be configured on the same SRS resource.
After the step 51, the terminal may perform uplink transmission according to the resource and/or port for uplink transmission indicated by the first resource. In this way, the base station may perform sounding, for example, perform channel sounding, according to the resource and/or port for uplink transmission indicated by the first resource, so as to obtain uplink channel information.
After the step 51, the base station may further send a first scheduling signaling for scheduling first uplink data transmission to the terminal, where the terminal receives the first scheduling signaling sent by the base station, and the first scheduling signaling indicates a resource and/or a port that can be used for first uplink data transmission in a target first resource; the target first resource is a resource and/or a port in a first resource used by a certain specific uplink transmission of the terminal, or the target first resource is a resource and/or a port in a first resource indicated by the first scheduling signaling (i.e., the first resource is indicated in the first scheduling signaling). The specific uplink transmission may be a predetermined uplink transmission, such as the last uplink transmission of the terminal, or other uplink transmissions. And the terminal performs first uplink data transmission according to the resource and/or port which can be used for first uplink data transmission in the target first resource indicated by the first scheduling signaling. In this way, the terminal may perform uplink data transmission using resources available for uplink transmission in the first resources for antenna switching.
Specifically, the port used for the first uplink data transmission may be the same as the port available for uplink transmission in the target first resource indicated by the first scheduling signaling. In addition, when the first resource configuration or the indicated ports available for uplink transmission are not on the same SRS resource, the first scheduling signaling may indicate only the resources available for the first uplink data transmission in the target first resource, and does not indicate a specific port.
In this embodiment of the present invention, the terminal may further receive second configuration information sent by the base station, where the second configuration information is used to configure a second resource used for uplink transmission of a codebook, and the second resource is at least one SRS resource or an SRS resource set.
Specifically, the terminal may receive the configuration of the second resource sent by the base station through RRC signaling or MAC CE, where the configuration of the second resource includes at least one of the following:
1) a resource type or time domain behavior of the second resource is aperiodic transmission;
2) the power control parameter of the second resource is the same as the power control parameter of the first resource;
3) and the reference resource of the spatial relationship information of the second resource is a resource and/or a port which can be used for uplink transmission in the first resource.
By configuring the periodic first resource and the aperiodic second resource in this way, it is possible to reduce the frequency of transmission of the periodic SRS, reduce the overhead of the SRS system and the power consumption of the terminal, and maintain the base station's knowledge of the state of the basic channel of the terminal. On the other hand, the aperiodic SRS indicated by the DCI may be used to acquire the latest channel state information when the base station needs it, so that the base station may schedule the terminal based on the more accurate channel information.
Based on the above configuration, the terminal may perform uplink transmission according to a resource and/or a port that is available for uplink transmission in the second resource and/or the first resource.
In the embodiment of the present invention, the terminal may further receive a second scheduling signaling sent by the base station and used for scheduling second uplink data transmission, where the second scheduling signaling indicates a resource and/or a port that can be used for second uplink data transmission in a target second resource; the target second resource is a resource and/or a port in a second resource used by a certain specific uplink transmission (such as the last uplink transmission or an agreed other uplink transmission), or the target second resource is a resource and/or a port in a second resource indicated by the second scheduling signaling (i.e., the second resource is indicated in the second scheduling signaling). In this way, the terminal may perform the second uplink data transmission according to the resource and/or port, which may be used for the second uplink data transmission, in the target second resource indicated by the second scheduling signaling.
Optionally, the antenna port used for the second uplink data transmission may be the same as the port available for uplink transmission in the target second resource indicated by the second scheduling signaling. And when the second resource configuration or the indicated ports available for uplink transmission are not on the same SRS resource, the second scheduling signaling may indicate only the resources available for second uplink data transmission in the target second resource, without indicating a specific port.
In this embodiment of the present invention, the terminal may further receive a third scheduling signaling sent by the base station and used for scheduling third uplink data transmission, where the third scheduling signaling indicates a resource and/or a port that can be used for third uplink data transmission in the target third resource. Then, the terminal may perform third uplink data transmission according to a resource and/or a port, which may be used for third uplink data transmission, in the target third resource indicated by the third scheduling signaling.
When the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal for the last uplink transmission is the first resource, the target third resource is: a resource and/or port in the first resource;
when the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal for the last uplink transmission is the second resource, the target third resource is: a resource and/or port in the second resource;

Here, the antenna port used for the third uplink data transmission is the same as the port available for uplink transmission in the resource indicated by the third scheduling signaling. And when the first resource or the second resource configuration or the indicated ports available for uplink transmission are not on the same resource, the third scheduling signaling only indicates the resources available for the third uplink data transmission, and does not indicate a specific port.
Optionally, the terminal may further receive third configuration information sent by the base station, where the third configuration information is used to configure a third resource used for antenna switching and configure a resource and/or a port that can be used for uplink transmission in the third resource, and the third resource is at least one SRS resource or an SRS resource set.

Based on the above configuration, the terminal performs uplink transmission according to the resource and/or port that can be used for uplink transmission in the third resource and/or the first resource.
In the embodiment of the present invention, the terminal may further receive a fourth scheduling signaling sent by the base station and used for scheduling fourth uplink data transmission, where the fourth scheduling signaling indicates a resource and/or a port that can be used for the fourth uplink data transmission in a target fourth resource; the target fourth resource is a resource and/or a port in a third resource used by a specific uplink transmission (such as the last uplink transmission or other agreed uplink transmissions) of the terminal at a time, or the target fourth resource is a resource and/or a port in the third resource indicated by the fourth scheduling signaling.

and the terminal performs fifth uplink data transmission according to a resource and/or a port which can be used for fifth uplink data transmission in the target fifth resource indicated by the fifth scheduling signaling.
When the fifth scheduling signaling does not indicate the first resource or the third resource, if the resource used by a certain specific uplink transmission (such as the latest uplink transmission or other agreed uplink transmissions) of the terminal is the first resource, the target fifth resource is: a resource and/or port in the first resource;

In addition, when the first resource or the third resource configuration or the indicated port available for uplink transmission is not on the same resource, the fifth scheduling signaling indicates only the resource available for fifth uplink data transmission, and does not indicate a specific port.
The flow of the method of the embodiment of the invention at the base station and the terminal side is introduced above. To facilitate a better understanding of embodiments of the present invention, a more detailed description is provided below by way of several examples.
Example 1:
the base station configures an SRS resource set #1, and the usage (use) is for antenna switching (antenna switching), so that the SRS resource set can be used for acquiring downlink channel information. The base station further indicates that part of resources or ports in set #1 may be used for uplink traffic transmission, such as codebook-based uplink data transmission, such as resource 1.1 and/or port 1.1.
When the base station indicates the terminal to perform uplink data transmission through the DCI, the base station may directly indicate the resource 1.1 and/or the port 1.1, and the terminal performs uplink service transmission according to the SRS resource 1.1 and/or the port 1.1.
Example 2:
the base station configures an SRS resource set #1, and the use is used for antenna switching (antenna switching) to acquire downlink channel information. The base station further indicates that a part of resources or ports therein may be used for uplink traffic transmission, such as uplink data transmission based on codebook, for example, resource 1.1 or port 1.1.
The base station configures a resource or a resource set #2 for uplink codebook-based data transmission, which may be non-periodically transmitted. In addition, the reference signal or the port of the spatial relationship may be configured as resource 1.1 or port 1.1 for the resource. The power control parameter configuration of this resource is the same as resource or port 1.1.
When the base station indicates the terminal to perform uplink data transmission through the DCI, the base station may indicate the set #2 resource, and may further indicate the set #2 resource to be used for uplink traffic transmission.
1) Before the DCI, the terminal sends the SRS resource for downlink traffic (e.g., antenna switching) transmission most recently, and indicates the resource or port for uplink transmission, e.g., codebook transmission, in the corresponding downlink SRS resource.
2) And if the SRS resource which is used for uplink service transmission and is sent by the terminal before the DCI, the DCI indicates the SRS resource or the port.
3) The DCI may also directly indicate a resource or a port for uplink transmission (e.g., codebook) in SRS resources for downlink traffic (e.g., antenna switching) transmission that are sent by a terminal at a certain time
4) The DCI may also directly indicate a resource or a port in an SRS resource of uplink traffic transmission transmitted by the terminal at a certain time.
Example 3:
the base station configures an SRS resource set #1, and the use is used for antenna switching (antenna switching) to acquire downlink channel information. The base station further indicates that a part of resources or ports therein may be used for uplink traffic transmission, such as uplink data transmission based on codebook, for example, resources or ports 1.1, 1.2.
The base station configures a resource or resource set #3 for downlink transmission, such as an antipna switching, and further indicates that the resource or port therein may be used for uplink traffic transmission, such as codebook-based uplink transmission, wherein the port or resource is 3.1, 3.2 or port 3.1, 3.2. And the corresponding spatial relationship between the resource and the port can configure that the reference signal is 1.1 or 1.2 of the SRS resource or the port. The configured power control parameters need to be the same as the SRS resources described above.
When the base station indicates the terminal to perform uplink data transmission through the DCI, the base station may indicate the resource #3, and may further use the resource in the resource set for the port of uplink service transmission.
1) Before the DCI, the terminal sends an SRS resource #1 for downlink traffic transmission, and indicates a resource or a port, for example, 1.1, for uplink transmission, such as codebook transmission, in the corresponding downlink SRS resource.
2) If the terminal transmits SRS resource #3 for uplink traffic transmission before DCI, the DCI needs to indicate the SRS, for example, 3.1.
Example 4:
the base station configures SRS resource set #1, which indicates that resources or ports #1.1, 1.2, 1.3 and 1.4 can be used for the antipna switch, and #1.2 and #1.3 can be used for the transmission of the uplink basic codebook. I.e. the resource set can simultaneously support multiple uses.
Example 5:
as shown in fig. 6, the base station configures SRS resource set, and the corresponding resources are SRS #1 and SRS #2, SRS #1 includes Port 1(Port1) and Port 2(Port2), and SRS #2 includes Port 3(Port3) and Port 4(Port 4).
The base station may further indicate that the resource SRS #1 may be used for codebook-based uplink transmission, and may indicate SRS #1 for uplink transmission when scheduling uplink transmission through DCI.
If the base station indicates that port1 and port3 are used for uplink transmission, since ports 1 and 3 are not on the same SRS resource, port1 and/or port3 may be indicated for uplink transmission when uplink transmission is scheduled through DCI.
