Furthermore, the separate design for uplink and downlink channel information acquisition leads to high system overhead and high terminal power consumption.
The base station configures periodic and aperiodic SRS resources for the terminal, obtains the latest channel state information by instructing the aperiodic SRS signal through DCI, and simultaneously uses antenna switching SRS resources to obtain downlink and uplink channel information.
It achieves reduced system overhead and terminal power consumption without increasing SRS resources, improves the flexibility and accuracy of channel information acquisition, and supports better acquisition of channel information combining periodic and aperiodic modes.

Abstract
Description
Technical Field
[0001] This invention relates to the field of mobile communication technology, specifically to a resource allocation method, a terminal, and a base station. Background Technology
[0002] Currently, codebook-based uplink transmission can only support one set of Sounding Reference Signals (SRS), and each resource set can only have one type of timing behavior, such as periodic or aperiodic. Supporting only periodic or aperiodic transmission is not optimal for the system. The advantages and disadvantages of supporting only periodic or aperiodic operation are analyzed below:
[0003] Periodic configuration ensures that the base station always receives uplink channel information and performs scheduling, but it lacks flexibility. Channel information between transmissions is difficult to obtain accurately, failing to meet the demands of services that arise at any time. Increasing the period density increases terminal power consumption, consumes more SRS resources, and reduces the capacity of the network's SRS. If the period is too long, it affects the accuracy of the channel information.
[0004] For non-periodic configurations, there are advantages such as high immediacy and low overall system overhead. However, the lack of prior information makes the accuracy of a single measurement challenging. In addition, multiple schedulings can lead to signaling overhead issues related to downlink control information (DCI).
[0005] Looking towards broader future applications, such as higher mobile speeds (e.g., 30 km / h), the requirements for SRS transmission density and frequency are even higher. As mentioned above, theoretically, more frequent SRS transmissions can help base stations obtain channel status information better, but this also brings significant system overhead and increased energy consumption due to frequent terminal transmissions.
[0006] Currently, SRS transmission supports four different operating modes or uses:
[0007] 1) Uplink beam management, mainly used for acquiring uplink channel information;
[0008] 2) Uplink codebook transmission is mainly used for acquiring uplink channel information and to assist uplink data transmission based on the codebook.
[0009] 3) Uplink non-codebook transmission is mainly used for acquiring uplink channel information and to assist uplink data transmission based on non-codebook.
[0010] 4) Antenna Switching is mainly used to acquire downlink channel information and assist in the transmission of downlink data.
[0011] Each working mode is configured according to a set of SRS resource sets, and the time behavior of each resource set is consistent, which can only be periodic, semi-continuous, or aperiodic.
[0012] Due to the design limitations of DCI, the SRS Resource Indicator (SRI) has limited indication information, and uplink codebook transmission and non-codebook transmission can only support one SRS resource set.
[0013] Furthermore, existing protocols design uplink and downlink channel information acquisition separately. Antenna-switching-based SRS transmission is primarily used to acquire downlink channel state information. The other three usage-based SRS transmissions mainly serve uplink traffic transmission. The following operations are supported under the antenna-switching-based SRS transmission method:
[0014] 1) 1T2R:
[0015] Two SRS resource sets can be configured, each containing two SRS resources, which are transmitted on different symbols, and each resource contains one port.
[0016] 2)2T4R
[0017] Two SRS resource sets can be configured, each set containing two SRS resources, which are transmitted on different symbols, and each resource contains two ports.
[0018] 3) 1T4R
[0019] For periodic transmissions, four resources can be configured, each on a different symbol, with each resource corresponding to a port.
[0020] 4) 1T1R, 2T2R, 4T4R
[0021] Two SRS resource sets can be configured, each set containing one SRS resource, and each resource corresponds to 1 / 2 / 4 ports.
[0022] The above 1T2R configuration indicates that the terminal is configured as 1T2R (one transmit port / antenna, two receive ports / antennas). Here, T represents transmit and R represents receive. The SRS transmission in 2T4R configuration is as follows... Figure 1 As shown, each group includes two SRS resources. One SRS resource is configured with port 1 and port 2 (Port1, 2), and the other SRS resource is configured with port 3 and port 4 (Port3, 4).
[0023] As can be seen from the above, current technologies only support two transmission methods for uplink: codebook-based and non-codebook-based. Each transmission method only supports one SRS resource set configuration. Each SRS resource set configuration can only support either periodic or aperiodic behavior, and cannot achieve a combination of periodic and aperiodic transmission methods. Furthermore, existing protocols treat uplink and downlink channel probing or channel information acquisition as two separate processes. Theoretically, two SRS configurations are needed to acquire the respective channel information, resulting in significant overhead. Summary of the Invention

[0166] The following description provides examples and is not intended to limit the scope, applicability, or configuration set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the spirit and scope of this disclosure. Various procedures or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with reference to certain examples may be combined in other examples.
[0167] Please see Figure 3 , Figure 3 This diagram illustrates a block diagram of a wireless communication system applicable to an embodiment of the present invention. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a user terminal or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle device, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment of the present invention. Network device 12 can be a base station and / or a core network element. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB, etc.), or a base station in other communication systems (e.g., eNB, WLAN access point, or other access point, etc.). The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in the embodiments of the present invention, only the base station in the NR system is used as an example, but the specific type of base station is not limited.
[0168] The base station can communicate with terminal 11 under the control of a base station controller, which in various examples may be part of the core network or some base stations. Some base stations may communicate control information or user data with the core network via backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. The wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on 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, etc.
[0169] The base station can wirelessly communicate with terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of an access point can be divided into sectors that constitute only a part of that coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). Base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. 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 the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.
[0170] Communication links in a wireless communication system may include 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). UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both.
[0171] As described in the background section, in the prior art, terminals may encounter unexpected situations such as cell access failure, slice access failure, or slice QoS rollback after cell reselection or access, which seriously affects the user experience. In order to solve at least one of the above problems, this embodiment of the invention provides a resource configuration method that can reduce or avoid the occurrence of the above situations, improve communication efficiency, and improve the user experience.
[0172] As described in the background section, existing technologies can only support either periodic or aperiodic SRS transmission. However, combining periodic and aperiodic SRS can effectively solve the problems associated with simply supporting either periodic or aperiodic transmission. Figure 3 As shown, the terminal can periodically transmit SRS reference signals in a relatively sparse manner, and when needed, based on DCI indication, transmit aperiodic SRS signals between two periodic SRS transmissions. On the one hand, by reducing the transmission frequency of periodic SRS, the overhead of the SRS system and the power consumption of the terminal are reduced, while maintaining the base station's understanding of the UE's basic channel status. On the other hand, through aperiodic SRS indicated by DCI, the latest channel state information can be obtained when the base station needs it, enabling the base station to schedule the base station based on more accurate channel information.
[0173] Please refer to Figure 4 The resource allocation method provided in this embodiment of the invention, when applied to the base station side, includes:
[0174] Step 41: The base station configures a first resource for antenna switching for the terminal, and configures or indicates the resources and / or ports in the first resource that can be used for uplink transmission. The first resource is at least one SRS resource or a set of SRS resources.
[0175] Through the above steps, this embodiment of the invention configures a first resource for antenna switching. Thus, SRS transmission based on antenna switching enables the base station to obtain downlink channel information. Furthermore, the first resource also includes resources and / or ports that can be used for uplink transmission, assisting the base station in obtaining uplink channel information and serving uplink service transmission, thereby enabling the first resource to serve multiple purposes.
[0176] Specifically, the base station can configure the first resource via Radio Resource Control (RRC) signaling or Media Access Control and Control Unit (MACCE), and the configuration of the first resource includes at least one of the following:
[0177] 1) The resource type or temporal behavior of the first resource is periodic transmission;
[0178] 2) The uplink transmission is a codebook-based uplink transmission;
[0179] 3) The ports available 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, these ports can be configured on the same SRS resource.
[0180] With the above configuration, the base station can perform probing based on the resources and / or ports indicated by the first resource for uplink transmission, such as channel probing, to obtain uplink channel information.
[0181] Following step 41 above, the base station may further send a first scheduling signaling to the terminal for scheduling the first uplink data transmission. This first scheduling signaling indicates resources and / or ports in the target first resource that can be used for the first uplink data transmission. Specifically, the first scheduling signaling may be a DCI (Distributed Control Information Center). The target first resource is either a resource and / or port in a first resource used by the terminal for a specific uplink transmission, or it may be a resource and / or port in the first resource indicated by the first scheduling signaling (i.e., the first scheduling signaling indicates the first resource). The specific uplink transmission may be a pre-agreed uplink transmission, such as the terminal's most recent uplink transmission, or another uplink transmission. In this way, the terminal can utilize the resources in the first resource used for antenna switching that are available for uplink transmission to perform uplink data transmission. Furthermore, it should be noted that in this document, "resources and / or ports" typically refer to SRS resources and / or ports.
[0182] Specifically, the port used for the first uplink data transmission can be the same as the port available for uplink transmission in the target first resource indicated by the first scheduling signaling. Furthermore, when the ports available for uplink transmission configured or indicated by the first resource are not on the same SRS resource (e.g., ports available for uplink transmission include port 1 and port 2, where port 1 is on SRS resource 1 and port 2 is on SRS resource 2), the first scheduling signaling can only indicate the resource in the target first resource available for the first uplink data transmission, without indicating a specific port.
[0183] Optionally, the base station may also configure a second resource for the terminal to transmit the codebook uplink, wherein the second resource is at least one SRS resource or a set of SRS resources.
[0184] Specifically, the base station can configure the second resource via RRC signaling MAC CE, and the configuration of the second resource includes at least one of the following:
[0185] 1) The resource type or temporal behavior of the second resource is aperiodic transmission;
[0186] 2) The power control parameters of the second resource are the same as those of the first resource;
[0187] 3) The reference resources for the spatial relationship information of the second resource are the resources and / or ports in the first resource that can be used for uplink transmission.
[0188] In this way, the base station can configure periodic first resources and aperiodic second resources, thereby reducing the overhead of the SRS system and the power consumption of the terminal by decreasing the transmission frequency of periodic SRS, while maintaining the base station's understanding of the terminal's basic channel status. On the other hand, through aperiodic SRS indicated by DCI, the base station can obtain the latest channel state information when needed, enabling it to schedule terminals based on more accurate channel information.
[0189] Based on the above configuration, the base station can perform probing based on the second resource. Alternatively, the base station can perform probing separately or jointly based on the second resource and the resources and / or ports in the first resource that are available for uplink transmission. Here, separate probing means probing based on the second resource and probing based on the resources and / or ports in the first resource that are available for uplink transmission; joint probing means probing based on the second resource and the resources and / or ports in the first resource that are available for uplink transmission. For example, joint probing could be probing SRS jointly transmitted by the terminal in multiple time slots, or probing multiple SRS that are time-bundled.
[0190] In this embodiment of the invention, the base station may also send a second scheduling signaling (specifically, DCI) to the terminal for scheduling the second uplink data transmission. The second scheduling signaling indicates resources and / or ports in the target second resource that can be used for the second uplink data transmission. The target second resource is a resource and / or port in the second resource used by a specific uplink transmission of the terminal (such as the most recent uplink transmission, or other agreed uplink transmissions), or the target second resource is a resource and / or port in the second resource indicated by the second scheduling signaling (i.e., the second scheduling signaling indicates the second resource).
[0191] Optionally, the antenna port used for the second uplink data transmission can be the same as the port available for uplink transmission in the target second resource indicated by the second scheduling signaling. However, when the ports available for uplink transmission in the second resource configuration or indication are not on the same SRS resource, the second scheduling signaling can only indicate the resources in the target second resource available for the second uplink data transmission, without indicating a specific port.
[0192] Optionally, the base station may also send a third scheduling signaling to the terminal for scheduling third uplink data transmission, the third scheduling signaling indicating resources and / or ports in the target third resource that can be used for third uplink data transmission.
[0193] Wherein, when the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal in its most recent uplink transmission is the first resource, then the target third resource is: the resource and / or port in the first resource;
[0194] When the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal in its most recent uplink transmission is the second resource, then the target third resource is: the resource and / or port in the second resource;
[0195] When the third scheduling signaling indicates a first resource or a second resource, the target third resource is: the resource and / or port in the first or second resource indicated by the third scheduling signaling.
[0196] 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. However, when the ports available for uplink transmission configured or indicated by the first or second resource are not on the same resource, the third scheduling signaling only indicates the resource available for the third uplink data transmission, without indicating a specific port.
[0197] Optionally, the base station may also configure a third resource for antenna switching for the terminal, and configure resources and / or ports in the third resource that can be used for uplink transmission, wherein the third resource is at least one SRS resource or a set of SRS resources.
[0198] Specifically, the base station can configure the third resource via RRC signaling MAC CE, and the configuration of the third resource includes at least one of the following:
[0199] 1) The resource type or temporal behavior of the third resource is transmitted non-periodicly;
[0200] 2) The power control parameters of the third resource are the same as those of the first resource;
[0201] 3) The reference resources for the spatial relationship information of the third resource are the resources and / or ports in the first resource that can be used for uplink transmission.
[0202] Based on the above configuration, the base station can perform probing based on the third resource, or the base station can perform probing or joint probing based on the third resource and the resources and / or ports available for uplink transmission in the first resource. Joint probing can be probing SRS jointly transmitted by the terminal in multiple time slots, or probing multiple SRS bundled in time.
[0203] In this embodiment of the invention, the base station may further send a fourth scheduling signaling to the terminal for scheduling fourth uplink data transmission. The fourth scheduling signaling indicates resources and / or ports in a target fourth resource that can be used for the fourth uplink data transmission. Here, the target fourth resource is a resource and / or port in a third resource used by the terminal for a specific uplink transmission (such as the most recent uplink transmission, or other agreed uplink transmissions), or the target fourth resource is a resource and / or port in a third resource indicated by the fourth scheduling signaling.
[0204] Optionally, the antenna port used for the fourth uplink data transmission is the same as the port available for uplink transmission in the target fourth resource indicated by the fourth scheduling signaling.
[0205] In this embodiment of the invention, the base station may also send a fifth scheduling signaling to the terminal for scheduling the fifth uplink data transmission, wherein the fifth scheduling signaling indicates the resources and / or ports in the target fifth resources that can be used for the fifth uplink data transmission;
[0206] Wherein, when the fifth scheduling signaling does not indicate the first resource or the third resource, if the resource used by the terminal in a certain uplink transmission (such as the most recent uplink transmission, or other agreed uplink transmissions) is the first resource, then the target fifth resource is: the resource and / or port in the first resource;
[0207] When the fifth scheduling signaling does not indicate the first resource or the third resource, if the resource used by the terminal in a specific uplink transmission (such as the most recent uplink transmission, or other agreed uplink transmissions) is the third resource, then the target fifth resource is: the resource and / or port among the resources of the third resource that can be used for uplink transmission;
[0208] When the fifth scheduling signaling indicates a first resource or a third resource, the target fifth resource is: the resource and / or port in the first or third resource indicated by the fifth scheduling signaling.
[0209] Optionally, the antenna port used for the fifth uplink data transmission is the same as the port available for uplink transmission in the transmission resources indicated by the fifth scheduling signaling. Alternatively, if the ports available for uplink transmission configured or indicated by the first or third resource are not on the same resource, the fifth scheduling signaling only indicates the resources available for the fifth uplink data transmission, without indicating a specific port.
[0210] As can be seen from the above, the embodiments of the present invention utilize SRS transmission to enable the base station to obtain not only downlink channel information but also assist the base station in obtaining uplink channel information. Furthermore, the embodiments of the present invention can achieve joint transmission of periodic and aperiodic SRS without increasing SRS resources, thereby reducing SRS transmission resources and supporting a better method for obtaining combined periodic and aperiodic channel information. Additionally, the embodiments of the present invention can reuse existing DCI related indications without increasing the SRS resource set.
[0211] The following describes the method of receiving embodiments of the present invention from the terminal side.
[0212] like Figure 5 As shown, the resource configuration method of this invention, when applied to the terminal side, includes:
[0213] Step 51: The terminal receives first configuration information sent by the base station. The first configuration information is used to configure a first resource for antenna switching, and resources and / or ports in the first resource that can be used for uplink transmission. The first resource is at least one SRS resource or a set of SRS resources.
[0214] Through the above steps, by configuring a first resource for antenna switching, the base station can obtain downlink channel information based on the antenna switching-based SRS sent by the terminal. Additionally, the first resource also includes resources and / or ports that can be used for uplink transmission, assisting the base station in obtaining uplink channel information and serving uplink service transmission, thus enabling the first resource to have multiple uses.
[0215] Specifically, the terminal can receive configuration information for the first resource sent by the base station via RRC signaling or MAC CE, wherein the configuration of the first resource includes at least one of the following:
[0216] 1) The resource type or temporal behavior of the first resource is periodic transmission;
[0217] 2) The uplink transmission is a codebook-based uplink transmission;
[0218] 3) The ports available 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, these ports can be configured on the same SRS resource.
[0219] After step 51 above, the terminal can perform uplink transmission based on the resources and / or ports indicated by the first resource for uplink transmission. In this way, the base station can perform probing, such as channel probing, based on the resources and / or ports indicated by the first resource for uplink transmission, thereby obtaining uplink channel information.
[0220] Following step 51 above, the base station may further send a first scheduling signaling to the terminal for scheduling the first uplink data transmission. The terminal receives the first scheduling signaling sent by the base station. The first scheduling signaling indicates resources and / or ports in a target first resource that can be used for the first uplink data transmission. The target first resource is a resource and / or port in a first resource used by the terminal for a specific uplink transmission, or the target first resource is a resource and / or port in a first resource indicated by the first scheduling signaling (i.e., the first scheduling signaling indicates the first resource). The specific uplink transmission may be a pre-agreed uplink transmission, such as the terminal's most recent uplink transmission, or other uplink transmissions. The terminal performs the first uplink data transmission according to the resources and / or ports in the target first resource indicated by the first scheduling signaling that can be used for the first uplink data transmission. In this way, the terminal can utilize the resources in the first resource used for antenna switching that can be used for uplink transmission to perform uplink data transmission.
[0221] Specifically, the port used for the first uplink data transmission can be the same as the port available for uplink transmission in the target first resource indicated by the first scheduling signaling. Alternatively, when the ports available for uplink transmission configured or indicated by the first resource are not on the same SRS resource, the first scheduling signaling can only indicate the resource in the target first resource that can be used for the first uplink data transmission, without indicating a specific port.
[0222] In this embodiment of the invention, the terminal may also receive second configuration information sent by the base station. The second configuration information is used to configure a second resource for uplink transmission of the codebook. The second resource is at least one SRS resource or a set of SRS resources.
[0223] Specifically, the terminal can receive configuration information for the second resource sent by the base station via RRC signaling or MAC CE, wherein the configuration of the second resource includes at least one of the following:
[0224] 1) The resource type or temporal behavior of the second resource is aperiodic transmission;
[0225] 2) The power control parameters of the second resource are the same as those of the first resource;
[0226] 3) The reference resources for the spatial relationship information of the second resource are the resources and / or ports in the first resource that can be used for uplink transmission.
[0227] In this way, by configuring periodic first resources and aperiodic second resources, the overhead of the SRS system and the power consumption of the terminal can be reduced by decreasing the transmission frequency of periodic SRS, while maintaining the base station's understanding of the terminal's basic channel status. On the other hand, aperiodic SRS indicated by DCI can be used to obtain the latest channel state information when the base station needs it, enabling the base station to schedule terminals based on more accurate channel information.
[0228] Based on the above configuration, the terminal can perform uplink transmission according to the second resource and / or the resources and / or ports in the first resource that can be used for uplink transmission.
[0229] In this embodiment of the invention, the terminal may further receive a second scheduling signaling sent by the base station for scheduling the second uplink data transmission. The second scheduling signaling indicates resources and / or ports in a target second resource that can be used for the second uplink data transmission. The target second resource is a resource and / or port in a second resource used by a specific uplink transmission of the terminal (such as the most recent uplink transmission, or other agreed-upon uplink transmissions), or the target second resource is a resource and / or port in a second resource indicated by the second scheduling signaling (i.e., the second scheduling signaling indicates two resources). Thus, the terminal can perform the second uplink data transmission according to the resources and / or ports in the target second resource indicated by the second scheduling signaling that can be used for the second uplink data transmission.
[0230] Optionally, the antenna port used for the second uplink data transmission can be the same as the port available for uplink transmission in the target second resource indicated by the second scheduling signaling. However, when the ports available for uplink transmission in the second resource configuration or indication are not on the same SRS resource, the second scheduling signaling can only indicate the resources in the target second resource available for the second uplink data transmission, without indicating a specific port.
[0231] In this embodiment of the invention, the terminal may further receive a third scheduling signaling sent by the base station for scheduling third uplink data transmission. The third scheduling signaling indicates resources and / or ports in the target third resources that can be used for third uplink data transmission. Then, the terminal can perform third uplink data transmission according to the resources and / or ports in the target third resources indicated by the third scheduling signaling that can be used for third uplink data transmission.
[0232] Wherein, when the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal in its most recent uplink transmission is the first resource, then the target third resource is: the resource and / or port in the first resource;
[0233] When the third scheduling signaling does not indicate the first resource or the second resource, if the resource used by the terminal in its most recent uplink transmission is the second resource, then the target third resource is: the resource and / or port in the second resource;
[0234] When the third scheduling signaling indicates a first resource or a second resource, the target third resource is: the resource and / or port in the first or second resource indicated by the third scheduling signaling.
[0235] 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. However, when the ports available for uplink transmission configured or indicated by the first or second resource are not on the same resource, the third scheduling signaling only indicates the resource available for the third uplink data transmission, without indicating a specific port.
[0236] Optionally, the terminal may also receive third configuration information sent by the base station. The third configuration information is used to configure a third resource for antenna switching and to configure resources and / or ports in the third resource that can be used for uplink transmission. The third resource is at least one SRS resource or a set of SRS resources.
[0237] Specifically, the terminal can receive configuration information for the third resource sent by the base station via RRC signaling or MAC CE, wherein the configuration of the third resource includes at least one of the following:
[0238] 1) The resource type or temporal behavior of the third resource is transmitted non-periodicly;
[0239] 2) The power control parameters of the third resource are the same as those of the first resource;
[0240] 3) The reference resources for the spatial relationship information of the third resource are the resources and / or ports in the first resource that can be used for uplink transmission.
[0241] Based on the above configuration, the terminal performs uplink transmission according to the third resource and / or the resources and / or ports in the first resource that can be used for uplink transmission.
[0242] In this embodiment of the invention, the terminal may further receive a fourth scheduling signaling sent by the base station for scheduling fourth uplink data transmission. The fourth scheduling signaling indicates resources and / or ports in a target fourth resource that can be used for the fourth uplink data transmission. The target fourth resource is a resource and / or port in a third resource used by the terminal for a specific uplink transmission (such as the most recent uplink transmission, or other agreed-upon uplink transmissions), or the target fourth resource is a resource and / or port in a third resource indicated by the fourth scheduling signaling. Then, the terminal performs the fourth uplink data transmission according to the resources and / or ports in the target fourth resource indicated by the fourth scheduling signaling that can be used for the fourth uplink data transmission.
[0243] Optionally, the antenna port used for the fourth uplink data transmission is the same as the port available for uplink transmission in the target fourth resource indicated by the fourth scheduling signaling.
[0244] In this embodiment of the invention, the terminal may also receive a fifth scheduling signaling sent by the base station for scheduling the fifth uplink data transmission, wherein the fifth scheduling signaling indicates the resources and / or ports in the target fifth resources that can be used for the fifth uplink data transmission;
[0245] The terminal performs fifth uplink data transmission according to the resources and / or ports in the target fifth resource indicated by the fifth scheduling signaling that can be used for fifth uplink data transmission.
[0246] Wherein, when the fifth scheduling signaling does not indicate the first resource or the third resource, if the resource used by the terminal in a certain uplink transmission (such as the most recent uplink transmission, or other agreed uplink transmissions) is the first resource, then the target fifth resource is: the resource and / or port in the first resource;
[0247] When the fifth scheduling signaling does not indicate the first resource or the third resource, if the resource used by the terminal in a specific uplink transmission (such as the most recent uplink transmission, or other agreed uplink transmissions) is the third resource, then the target fifth resource is: the resource and / or port among the resources of the third resource that can be used for uplink transmission;
[0248] When the fifth scheduling signaling indicates a first resource or a third resource, the target fifth resource is: the resource and / or port in the first or third resource indicated by the fifth scheduling signaling.
[0249] Optionally, the antenna port used for the fifth uplink data transmission is the same as the port available for uplink transmission in the transmission resources indicated by the fifth scheduling signaling. Alternatively, if the ports available for uplink transmission configured or indicated by the first or third resource are not on the same resource, the fifth scheduling signaling only indicates the resources available for the fifth uplink data transmission, without indicating a specific port.
[0250] The above describes the process of the method of the present invention on the base station and terminal sides. To help better understand the embodiments of the present invention, further detailed explanations are provided below through several examples.
[0251] Example 1:
[0252] The base station configures SRS resource set set#1 for antenna switching, thereby enabling the acquisition of downlink channel information. The base station further indicates that some resources or ports in set#1 can be used for uplink service transmission, such as codebook-based uplink data transmission, such as resource 1.1 and / or port 1.1.
[0253] When the base station instructs the terminal to transmit uplink data via DCI, it can directly instruct resource 1.1 and / or port 1.1, and the terminal will then transmit uplink services based on SRS resource 1.1 and / or port 1.1.
[0254] Example 2:
[0255] The base station configures an SRS resource set set#1, with usage designated for antenna switching to acquire downlink channel information. The base station further indicates that some resources or ports within this set can be used for uplink service transmission, such as codebook-based uplink data transmission, e.g., resource 1.1 or port 1.1.
[0256] The base station configures a resource or resource set set#2 for uplink codebook-based data transmission. This resource or resource set can be transmitted aperiodically. Additionally, a spatial relationship reference signal or port can be configured for this resource as resource 1.1 or port 1.1. The power control parameters for this resource are configured the same as those for resource or port 1.1.
[0257] When a base station instructs a terminal to transmit uplink data via DCI, it can instruct the resources in set#2, and can further instruct the resources in set#2 to be used for uplink service transmission.
[0258] 1) If the terminal recently sent SRS resources for downlink services (such as antenna switching) before this DCI, then indicate the resources or ports in the corresponding downlink SRS resources used for uplink transmission, such as codebook transmission.
[0259] 2) If the terminal recently sent an SRS resource for uplink service transmission before the DCI, then the DCI indicates that SRS resource or port.
[0260] 3) DCI can also directly indicate the resources or ports in the SRS resources used for uplink transmission (such as codebook) in a single transmission by the terminal for downlink services (such as antenna switching).
[0261] 4) DCI can also directly indicate the resources or ports in the SRS resources of a certain uplink service transmission sent by the terminal.
[0262] Example 3:
[0263] The base station configures an SRS resource set set#1, with usage designated for antenna switching to acquire downlink channel information. The base station further indicates that some resources or ports within this set can be used for uplink service transmission, such as codebook-based uplink data transmission, e.g., resources or ports 1.1 and 1.2.
[0264] The base station configures resources or resource set set#3 for downlink transmission, such as antenna switching, and further indicates that the resources or ports within it can be used for uplink service transmission, such as codebook-based uplink transmission, where ports or resources are 3.1, 3.2 or ports 3.1, 3.2. The corresponding resource and port spatial relationship can be configured with a reference signal of SRS resource or port 1.1 or 1.2. Its configured power control parameters need to be the same as those of the aforementioned SRS resources.
[0265] When the base station instructs the terminal to perform uplink data transmission via DCI, it can indicate resource #3, and can further specify the resources in the resource set for the port used for uplink service transmission.
[0266] 1) Before this DCI, if the terminal sends SRS resource #1 for downlink service transmission, it indicates the resource or port in the corresponding downlink SRS resource used for uplink transmission, such as codebook transmission, for example, 1.1.
[0267] 2) If the terminal sends SRS resource #3 for uplink service transmission before the DCI, then the DCI needs to indicate the SRS, such as 3.1.
[0268] Example 4:
[0269] The base station is configured with SRS resource set #1, indicating that resources or ports #1.1, 1.2, 1.3, and 1.4 can be used for antenna switching, and #1.2 and #1.3 can be used for uplink basic codebook transmission.
