Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly to a supplementary uplink (SUL) carrier determination method, apparatus, related equipment, and storage medium. Background Technology

[0002] Compared to downlink, uplink coverage is more easily limited, and the demand for low-frequency bands is more urgent. Therefore, it is advisable to consider refarming at least one of the 900MHz, 1800MHz, F, A, and E bands for use as a 5G frequency band, employing a full uplink spectrum SUL approach for uplink enhancement. For existing or potential 5G frequencies, such as 4.9GHz, 6GHz, or millimeter waves, uplink capabilities can be enhanced using a supplementary downlink (SDL) (or TDD carrier) or SDL (or TDD carrier) + partial uplink (used only for feedback, such as Channel Sounding Reference Signal (SRS)). Furthermore, to further reduce network construction costs, a combination scheme of SUL + N (N>=1) SDL (or TDD carriers) is introduced, defining the association between SUL and SDL carriers (TDD carriers).

[0003] However, in related technologies, using an association scheme can cause inaccuracies in SUL selection, thereby reducing uplink performance. Summary of the Invention

[0097] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0098] In related technologies, SUL carriers are defined by associating downlink and uplink carriers one-to-one, which defines how to obtain the association relationship, as follows:

[0099] The first method is to obtain the correlation based on broadcast messages: When the terminal (which can also be understood as the user or user equipment (UE)) is in an idle state, it obtains information such as frame structure, system frequency, bandwidth, and SUL uplink common channel configuration (including correlation) by receiving broadcast messages SIB1 sent by the base station. This includes information on the Physical Random Access Channel (PRACH) (time and frequency resources, uplink carrier selection threshold, etc.), the Physical Uplink Control Channel (PUCCH), and the two channels PRACH.

[0100] The second method is to configure the association relationship based on RRC messages: when the terminal is in the connected state, the terminal obtains the association relationship by receiving the RRC reconfiguration message sent by the base station.

[0101] The above two methods can be summarized as follows: The configuration message sent from the network side to the terminal side carries one downlink configuration and / or one uplink configuration and / or multiple supplementary uplink configurations. Each supplementary uplink configuration may contain one or more Bandwidth Part (BWP) configurations. Alternatively, the configuration message sent from the network side to the terminal side carries one downlink configuration and / or one uplink configuration, where one uplink configuration contains multiple supplementary uplink configuration information. The configuration message sent from the network side to the terminal side can be a broadcast message or dedicated signaling.

[0102] When association relationships are configured, based on downlink cell definition (i.e., defining cells primarily using SDL or TDD downlink), the following three possible processes and issues exist in scenarios such as cell reselection, handover, redirection, and access failure:

[0103] (1) As Figure 1 As shown, if the SDL (or TDD downlink) changes while the SUL remains unchanged, a random access procedure is required due to the correlation, which will introduce unnecessary service interruption delay.

[0104] (2) Figure 1 As shown, if both SDL (or TDD downlink) and SUL change, the correlation will also cause SUL to become inaccurate, thus introducing uplink performance loss due to inaccurate carrier selection.

[0105] (3) Figure 1 As shown, if the SDL (or TDD downlink) remains unchanged but the SUL changes, the SDL (or TDD downlink) must be referenced. This will result in protocol process support without SUL as the main definition, and the complete process based on SUL (which can also be understood as the complete function based on SUL) needs to be indirectly implemented or introduced through SDL (or TDD downlink) or other means.

[0106] In addition, when the coverage difference between SDL (or TDD downlink) and SUL is too large, such as SUL being the 2.3GHz band (low frequency band) and SDL (or TDD downlink) being the 4.9GHz band (mid-to-high frequency band), changes in SUL (or changes in SDL (or TDD downlink) or no changes in SUL) may lead to inaccurate SUL selection, resulting in inaccurate access and consequently increased uplink interference or loss of uplink performance.

[0107] In summary, using an association-based approach can lead to inaccurate SUL selection, resulting in inaccurate access and consequently reduced uplink performance.

[0108] Based on this, in various embodiments of this application, the terminal reports its supported SUL carrier capabilities, and the network side selects an SUL carrier for the terminal based on the terminal's SUL carrier (or simply SUL) capabilities.

[0109] The solution in this application selects an SUL carrier for the terminal based on the terminal's SUL carrier capability, thereby selecting a more suitable SUL carrier from multiple SUL carriers through a refined indication method, improving the accuracy of SUL carrier selection, and thus improving uplink performance.

[0110] This application provides a SUL carrier determination method, applied to a terminal, such as... Figure 2 As shown, the method includes:

[0111] Step 201: Report the first information to the network side; the first information represents the SUL carrier capability supported by the terminal;

[0112] Step 202: Receive the second information sent by the network side; the second information represents the configuration information of the SUL carrier.

[0113] The first information may include at least one of the following:

[0114] Does the terminal support multiple SUL carriers?

[0115] Maximum number of SUL carriers scheduled;

[0116] The maximum number of SUL carriers that can be transmitted simultaneously.

[0117] Here, the maximum number of SUL carriers to be scheduled refers to the maximum number of SUL carriers to be scheduled if the terminal supports multiple SUL carriers.

[0118] The maximum number of SUL carriers that can be transmitted simultaneously refers to the maximum number of SUL carriers that can be transmitted simultaneously if the terminal supports multiple SUL carriers.

[0119] The maximum number of SUL carriers scheduled can also be understood as the format of dynamic SUL carrier scheduling supported by the terminal.

[0120] The maximum number of SUL carriers that can be transmitted simultaneously can also be understood as the maximum number of concurrent SUL carriers supported by the terminal.

[0121] In practical applications, in step 202, after receiving the first information, the network side will determine (or configure) a SUL carrier for the terminal based on the first information. That is, the terminal receives the second information sent by the network side based on the first information. Depending on the application scenario, the network side can instruct the terminal to use different SUL carriers, specifically including the following situations:

[0122] In the first scenario, the network side can send the SUL carrier configuration information associated with the downlink carrier of the cell where the terminal is located to the terminal, based on the terminal's capabilities.

[0123] Based on this, in one embodiment, the second information represents the configuration information of N SUL carriers, where N is an integer greater than or equal to 1; N represents the number of SUL carriers associated with the downlink carrier of the cell where the terminal is located.

[0124] In the second scenario, the network side can select at least one SUL carrier from N SUL carriers based on the terminal's capabilities and send configuration information of at least one SUL carrier from the configured N SUL carriers to the terminal.

[0125] Based on this, in one embodiment, the second information indicates at least one SUL carrier among the N SUL carriers configured for the terminal.

[0126] In the third scenario, the network side can select at least one SUL carrier to be activated from N SUL carriers based on the terminal's capabilities, and send configuration information of at least one SUL carrier from the at least one SUL carrier to be activated to the terminal.

[0127] Based on this, in one embodiment, the second information indicates M active SUL carriers out of N SUL carriers configured for the terminal, where M is an integer greater than or equal to 1.

[0128] In the fourth scenario, the network side can also select at least one SUL carrier from the M active SUL carriers based on the terminal's capabilities and instruct the terminal accordingly.

[0129] Based on this, in one embodiment, the second information indicates at least one of the M SUL carriers activated by the terminal; the M activated SUL carriers belong to the N SUL carriers configured on the network side.

[0130] In the second, third, and fourth scenarios mentioned above, before executing step 202, the network side needs to configure the SUL carrier associated with the downlink carrier for the terminal, that is, configure the aforementioned association relationship, such as configuring 1 SDL (or TDD downlink) + N SULs. The serving cell SDL (or TDD downlink) of the terminal (also referred to as the terminal) defines N associated SUL carriers and corresponding carrier identifiers (which can be expressed as indicators in English) so that the network side can select a more suitable SUL carrier from the N SUL carriers for the terminal.

[0131] Based on this, in one embodiment, the method may further include:

[0132] Obtain information on N SUL carriers associated with the downlink carrier configured by the network side for the cell where the terminal is located.

[0133] In the fourth scenario described above, before executing step 202, the network side needs to configure the SUL carrier associated with the downlink carrier for the terminal, and also needs to indicate the M SUL carriers activated by the terminal.

[0134] Based on this, in one embodiment, the method may further include:

[0135] The terminal receives third information sent by the network side; the third information is used to instruct the terminal to activate M SUL carriers.

[0136] The terminal can receive third information sent by the network side in one of the following ways:

[0137] RRC message;

[0138] MAC CE;

[0139] DCI.

[0140] Here, when the terminal activates M SUL carriers simultaneously, it is not necessary to measure N SUL carriers in real time. Only M SUL carriers need to be maintained, which saves the terminal's power consumption and helps save power.

[0141] In practical applications, for terminals in idle state, the N SUL carrier information associated with the configured downlink carrier can be sent via system messages (such as SIB1) during power-on or initial access. For terminals in connected state, as described below, the N SUL carrier information associated with the configured downlink carrier can be sent via RRC messages (which can be called RRC signaling, such as RRC reconfiguration messages) during cell handover, reselection, cell access, etc.

[0142] In step 201, in practical applications, the first information can be reported simultaneously when reporting terminal capabilities; for example, the first information can be reported through a new information element (IE).

[0143] In practical applications, the terminal may only support one SUL carrier. In order for the terminal to work properly, the SUL carrier is the SUL carrier that the terminal supports.

[0144] Based on this, in one embodiment, when the first information indicates that the terminal only supports one SUL carrier (i.e., when the first information indicates that the terminal only supports one SUL carrier), the SUL carrier corresponding to the second information is one SUL carrier supported by the terminal.

[0145] In step 202, the terminal may receive the second information in one of the following ways:

[0146] RRC message;

[0147] MAC CE;

[0148] DCI.

[0149] Accordingly, embodiments of this application also provide a SUL carrier determination method, applied to network devices (specifically, a base station), such as... Figure 3 As shown, the method includes:

[0150] Step 301: Receive the first information reported by the terminal; the first information represents the SUL carrier capability supported by the terminal;

[0151] The first information includes at least one of the following:

[0152] Does the terminal support multiple SUL carriers?

[0153] Maximum number of SUL carriers scheduled;

[0154] The maximum number of SUL carriers that can be transmitted simultaneously.

[0155] Step 302: Send second information to the terminal; the second information represents the configuration information of the SUL carrier.

[0156] Upon receiving the first information, the network device determines the SUL carrier based on the first information to configure the terminal with the SUL carrier. Depending on the application scenario, the network device can instruct the terminal to use different SUL carriers, specifically including the following situations:

[0157] In the first scenario, the network device can send SUL carrier configuration information associated with the downlink carrier of the cell where the terminal is located to the terminal, based on the terminal's capabilities.

[0158] Based on this, in one embodiment, the second information represents the configuration information of N SUL carriers, where N is an integer greater than or equal to 1; N represents the number of SUL carriers associated with the downlink carrier of the cell where the terminal is located.

[0159] In the second scenario, the network device can select at least one SUL carrier from N SUL carriers based on the terminal's capabilities and send configuration information of at least one SUL carrier from the configured N SUL carriers to the terminal. In this way, the best SUL can be selected, thereby further improving uplink performance.

[0160] Based on this, in one embodiment, the second information indicates at least one SUL carrier among the N SUL carriers configured for the terminal.

[0161] In the third scenario, the network device can select at least one SUL carrier to be activated from N SUL carriers based on the terminal's capabilities, and send configuration information of at least one SUL carrier among the at least one SUL carrier to be activated to the terminal.

[0162] Based on this, in one embodiment, the second information indicates M active SUL carriers out of N SUL carriers configured for the terminal, where M is an integer greater than or equal to 1.

[0163] In the fourth scenario, the network device can also select at least one SUL carrier from the M active SUL carriers based on the terminal's capabilities and indicate this to the terminal. In this way, the best SUL can be selected, thereby further improving uplink performance.

[0164] Based on this, in one embodiment, the second information indicates at least one of the M SUL carriers activated by the terminal; the M activated SUL carriers belong to the N SUL carriers configured on the network side.

[0165] Here, in the second, third, and fourth scenarios described above, before executing step 302, the network device also needs to configure the SUL carrier associated with the downlink carrier for the terminal.

[0166] Based on this, in one embodiment, the method may further include:

[0167] Configure N SUL carrier information associated with the downlink carrier for the cell where the terminal is located.

[0168] In one embodiment, the network device may send the second information to the terminal in one of the following ways:

[0169] RRC message;

[0170] MAC CE;

[0171] DCI.

[0172] In practical applications, the network device may choose to send the second information to the terminal using one of the above methods as needed.

[0173] In the fourth scenario described above, before executing step 302, the network device needs to configure the SUL carrier associated with the downlink carrier for the terminal, and also needs to indicate the M SUL carriers activated by the terminal.

[0174] Based on this, in one embodiment, the method may further include:

[0175] Send a third message to the terminal; the third message instructs the terminal to simultaneously activate M SUL carriers.

[0176] In practical applications, the network device can send third information to the terminal in one of the following ways:

[0177] RRC message;

[0178] MAC CE;

[0179] DCI.

[0180] In practical applications, one of the above methods can be selected to send third information to the terminal as needed.

[0181] In one embodiment, the network device determines the SUL carrier based on the first information.

[0182] Specifically, when the first information indicates that the terminal only supports one SUL carrier, that is, when the first information indicates that the terminal only supports one SUL carrier, the carrier is determined to be one SUL carrier supported by the terminal.

[0183] When the first information indicates that the terminal supports multiple SUL carriers, that is, when the first information indicates that the terminal supports multiple SUL carriers, at least one SUL carrier is selected.

[0184] In practical applications, the network device can select a more suitable SUL carrier by combining the uplink reference signal information with the measurement results of uplink and downlink coverage differences and QCI service categories, based on the capabilities reported by the terminal.

[0185] Based on this, in one embodiment, when the first information indicates that the terminal supports multiple SUL carriers, the SUL carrier is determined based on the first information, the strength of the uplink reference signal, the measurement results of the uplink and downlink coverage differences, and the QCI of the service.

[0186] In practical applications, the uplink reference signal can be an SRS, etc.

[0187] Specifically, the network device selects M SUL carriers from N SUL carriers configured for the terminal based on the strength of the uplink reference signal;

[0188] Based on the measurement results of uplink and downlink coverage differences and the QCI of the service, at least one carrier is determined (i.e. selected) from M SUL carriers.

[0189] For example, assuming the terminal supports multiple SUL carriers, the maximum number of SUL carriers that can be dynamically scheduled is M, and the maximum number of concurrent SUL carriers is M, the network device selects M suitable SUL carriers from N SUL carriers based on the terminal's SRS information (specifically, each SUL carrier can be identified by a carrier identifier (i.e., an indicator)).

[0190] Specifically, for the uplink SRS transmitted by the terminal, for a certain SUL carrier (indicator x) among N SUL carriers, if the ratio of the reference signal received power (RSRP) of the SUL carrier to that of the other SUL carriers (such as indicator y or z) among the N SUL carriers is greater than a preset threshold (called THR1), then the SUL carrier is considered to be the selected SUL carrier, that is, the terminal belongs to the SUL carrier. This process continues until M SUL carriers are found, and the terminal is instructed to activate these M SUL carriers through MACCE.

[0191] Then, the network device configures thresholds (i.e., absThreshSS-BlocksConsolidation) and multiple synchronization signal blocks (SSBs) (i.e., nrofSS-BlocksToAverage) via RRC messages, and / or configures thresholds (absThreshCSI-RS-Consolidation) and multiple channel state information reference signals (CSI-RS) (i.e., nroCSI-RS-ResourcesToAverage), (these thresholds can be referred to as THR2), to determine the average RSRP (i.e., L3-RSRP) of the SSBs in nrofSS-BlocksToAverage that meet the absThreshSS-BlocksConsolidation threshold requirements, and / or the nroCSI-RS-ResourcesToAverage CSI-RS that meet the absThreshCSI-RS-Consolidation threshold requirements. The average RSRP (i.e., L3-RSRP) is determined by selecting the L3-RSRP that satisfies the preset threshold THR2 from the L3-RSRPs corresponding to M SUL carriers. Then, the SUL and SDL coverage difference offset (obtainable from live network testing results) is used to obtain L3-RSRP = L3-RSRP (determined by the network device) + Offset. The SUL service priority sequence is then obtained. The network device can use the SSB index to distinguish each SSB, and correspondingly, the CSI-RS index to distinguish each CSI-RS. The service priority sequence includes a one-to-one association between SUL indicators and QCIs; that is, each SUL indicator corresponds to one QCI. Multiple SUL indicators may correspond to the same QCI. For example, QCI = 5, and the corresponding SUL indicators are 2, 3, and 4.

[0192] Finally, the network device selects the SUL indicator corresponding to the largest L3-RSRP among the L3-RSRPs obtained from the QCIs of various services of the UE. In other words, it selects the SUL indicator corresponding to the largest L3-RSRP among the L3-RSRPs corresponding to the QCI of the service (of course, at least two SUL indicators with strong signal strength can also be selected as needed). That is, the SUL indicator of the SUL carrier is determined. Then, the second information is used to inform the relevant common channel configuration of the found SUL carrier for uplink access and service transmission.

[0193] When the network device determines M SUL carriers, it instructs the terminal to activate these M SUL carriers via MAC CE. The SUL indicator and MAC CE correspond one-to-one in ascending order. For example, if the SUL indicator is x and the M SUL carriers include SUL carriers with x=2, then MAC CE = 001000000….0 (with N bits).

[0194] In practical applications, the network device may not activate M SUL carriers, but instead directly select a carrier.

[0195] Based on this, in one embodiment, selecting at least one SUL carrier from multiple SUL carriers based on the first information, the strength of the uplink reference signal, the measurement results of the uplink and downlink coverage differences, and the QCI of the service includes:

[0196] Based on the measurement results of uplink and downlink coverage differences and the QCI of the service, Q SUL carriers are selected from the N SUL carriers configured for the terminal; Q is an integer greater than or equal to 1 and less than or equal to N;

[0197] Based on the strength of the uplink reference signal, at least one carrier is determined from the Q SUL carriers.

[0198] For example, the network device configures thresholds (i.e., absThreshSS-BlocksConsolidation) and SSBs (i.e., nrofSS-BlocksToAverage) via RRC messages, and / or configures thresholds (absThreshCSI-RS-Consolidation) and multiple Channel State Information Reference Signals (CSI-RS) (i.e., nroCSI-RS-ResourcesToAverage), (these thresholds may be referred to as THR2), to determine the average RSRP (i.e., L3-RSRP) of the SSBs in nrofSS-BlocksToAverage that meet the absThreshSS-BlocksConsolidation threshold requirements, and / or the nroCSI-RS-ResourcesToAverage CSI-RS that meet the absThreshCSI-RS-Consolidation threshold requirements. The average RSRP (i.e., L3-RSRP) is determined by selecting the L3-RSRP that satisfies the preset threshold THR2 from the L3-RSRPs corresponding to M SUL carriers. Then, the SUL and SDL coverage difference offset (which can be obtained through live network testing results) is combined to obtain L3-RSRP = L3-RSRP (determined by the network equipment) + Offset. Based on the obtained L3-RSRP and the QCI of each type of UE service, Q SUL carriers are selected from N SUL carriers. When selecting SUL carriers, the SUL carrier with the larger L3-RSRP is selected based on the service QCI. For example, assuming QCI = 5, the corresponding SUL indicators are 2, 3, and 4, and the SUL indicator with the larger L3-RSRP among these three SUL indicators is selected based on the service QCI.

[0199] Then, for the uplink SRS sent by the terminal, for a certain SUL carrier (indicator x) among the Q SUL carriers, if the ratio of the RSRP of the SRS received by the SUL carrier to that of the other SUL carriers (such as indicators y or z) among the N SUL carriers is greater than a preset threshold (called THR1), then the SUL carrier is considered to be the selected SUL carrier, that is, the terminal belongs to the SUL carrier, that is, the SUL carrier is determined; here, in practical applications, the process stops after finding a selected SUL carrier, of course, at least two SUL indicators with strong signal strength can also be selected as needed;

[0200] Finally, after the network equipment determines the SUL carrier, it uses DCI to instruct the terminal to configure the relevant common channel for the SUL carrier in order to perform uplink access and service transmission.

[0201] When using DCI, the SUL indicator and DCI correspond one-to-one in ascending order. For example, when SULindicator=3 and Q=4, DCI needs to use 2 bits to indicate 11.

[0202] As can be seen from the example above, based on the principle of selecting multiple SUL carriers according to the uplink SRS channel quality, and taking into account the measurement results of uplink and downlink coverage differences and QCI service categories, the user is instructed on the configuration of the SUL carrier-related common channels through DCI information.

The terminal reports its supported SUL carrier capability, and the network side selects an SUL carrier for the terminal based on the terminal's SUL carrier capability. This allows for the selection of a more suitable SUL carrier from multiple SUL carriers through a refined indication method, improving the accuracy of SUL carrier selection. This, in turn, improves uplink access accuracy, solves the uplink interference rise problem, and further enhances uplink performance, thereby effectively increasing user uplink throughput.
