Description

[0001] Divisional Application Instructions

[0002] This application is a divisional application of Chinese Patent Application No. 201880001495.6, filed on July 25, 2018, entitled "Transmission Configuration Method and Apparatus". Technical Field

[0003] This disclosure relates to the field of communication technology, and in particular to a transmission configuration method and apparatus. Background Technology

[0004] In next-generation communication systems, due to the rapid attenuation of high-frequency channels, beam-based transmission and reception are required to ensure coverage. In related technologies, beam management typically begins only after the terminal completes random access and RRC (Radio Resource Control) connection with the base station. However, after the random access process, before the base station configures the TCI (Transmission Configuration Indication) state set for the terminal, it must wait for a process involving beam measurement configuration, beam measurement, and beam measurement reporting. This increases the TCI configuration delay, preventing the terminal from using the most suitable receiving beam in a timely manner, further impacting the terminal's throughput.

[0179] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0180] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0181] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various types of information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, instruction information may also be referred to as second information, and similarly, second information may also be referred to as instruction information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0182] Figure 1 This is a flowchart illustrating a transmission configuration method according to an exemplary embodiment. Figure 2 This is an application scenario diagram illustrating a transmission configuration method according to an exemplary embodiment; the transmission configuration method can be used in a terminal, which can be a UE (User Equipment); such as Figure 1 As shown, the transmission configuration method may include the following steps 110-130:

[0183] In step 110, the SSB measurement configuration information sent by the base station is received.

[0184] In this embodiment of the disclosure, the SSB measurement configuration information may be configuration information configured by the base station for SSB measurement for the terminal, and sent to the terminal through a specified message, such as a system message.

[0185] In one embodiment, step 110 can be performed in the following way:

[0186] Receive SIB (System Information Block) 1 sent by the base station. SIB1 includes SSB measurement configuration information.

[0187] In one embodiment, the SSB measurement configuration information includes:

[0188] (1-1) Measurement object, the measurement object including one or more SSBs specified by the base station;

[0189] (1-2) Measurement triggering conditions, wherein the measurement triggering conditions include a specified measurement triggering threshold; wherein the specified measurement triggering threshold may be a specified SSB receive power threshold, or a power threshold of L1-RSRP (Layer 1-Reference Signal Received Power); or the specified measurement triggering threshold may be a specified SSB receive quality threshold, or a power threshold of L1-RSRQ (Reference Signal Received Quality).

[0190] (1-3) Configuration of the measurement report, which includes the specified content of the measurement report, or the specified content of the measurement report and the specified transmission resources of the measurement report. The specified content of the measurement report may be: an SSB identifier plus L1-RSRP and / or L1-RSRQ; the specified transmission resources may be PUCCH (Physical Uplink Control Channel) or PUSCH resources (Physical Uplink Shared Channel).

[0191] In the above (1-3), the base station can configure specified transmission resources for the measurement report, or it can choose not to configure specified transmission resources. If not configured, the resources configured by the base station for the terminal for transmitting the first specified message (i.e., the message used to characterize contention resolution during random access (Msg.3)) can be directly reused. The resource used for transmitting Msg.3 can be a PUCCH or PUSCH resource.

[0192] In step 120, SSB measurement is performed according to the SSB measurement configuration information to obtain an SSB measurement report.

[0193] In step 130, the SSB measurement report is sent to the base station via a first designated message. The first designated message is a message used to characterize contention resolution during random access, so that the base station can configure the TCI state set for the terminal based on the SSB measurement report.

[0194] In this embodiment of the disclosure, when the SSB measurement report is sent to the base station via the first designated message, the corresponding implementation method can be adopted according to whether the base station has configured designated transmission resources for the measurement report:

[0195] Method 1: The configuration of the measurement report does not include the specified transmission resources for the measurement report.

[0196] In this approach, the specific implementation process includes:

[0197] (2-1) Determine the first designated resource configured by the base station for the terminal to transmit the first designated message (Msg.3);

[0198] (2-2) Add the SSB measurement report to the first specified message (Msg.3);

[0199] (2-3) Using the first designated resource, the first designated message (Msg.3) carrying the SSB measurement report is sent to the base station.

[0200] As can be seen from the above method one: when the configuration of the measurement report does not include the designated transmission resources for the measurement report, the first designated resources used to transmit the first designated message (Msg.3) can be directly reused to send the first designated message (Msg.3) carrying the SSB measurement report to the base station.

[0201] Method 2: The measurement report configuration includes the specified transmission resources for the measurement report, but the specified transmission resources are different from those used to transmit Msg.3.

[0202] In this approach, the specific implementation process includes:

[0203] (3-1) Determine the second designated resource configured by the base station for the terminal to transmit the first designated message (Msg.3);

[0204] (3-2) When the second designated resource and the designated transmission resource are different, obtain the same temporary C-RNTI (Cell Radio Network Temporary Identifier) ​​as the first designated message (Msg.3);

[0205] In this embodiment of the disclosure, during the random access process, the random access feedback received by the terminal will include a temporary C-RNTI. This temporary C-RNTI is a dynamic identifier assigned to the terminal by the base station. The base station will also configure resources for the terminal to send Msg.3, so that the terminal can send Msg.3 including the temporary C-RNTI on the resources used to send Msg.3.

[0206] (3-3) The SSB measurement report is sent to the base station using the C-RNTI and the specified transmission resources.

[0207] As can be seen from Method 2 above: Although the SSB measurement report is not in the first specified message (Msg.3), it uses the same temporary C-RNTI as the first specified message (Msg.3).

[0208] Method 3: The configuration of the measurement report includes the specified transmission resources for the measurement report, but the specified transmission resources are the same as those used to transmit Msg.3.

[0209] (4-1) Determine the second designated resource configured by the base station for the terminal to transmit the first designated message (Msg.3);

[0210] (4-2) When the second designated resource and the designated transmission resource are the same, add the SSB measurement report to the first designated message;

[0211] (4-3) Use the second designated resource to send the first designated message carrying the SSB measurement report to the base station.

[0212] As can be seen from the above method three, when the configuration of the measurement report includes the designated transmission resource for the measurement report, but the designated transmission resource is the same as the resource used to transmit Msg.3, the second designated resource used to transmit the first designated message (Msg.3) can also be directly reused to send the first designated message (Msg.3) carrying the SSB measurement report to the base station.

[0213] In an instance scenario, such as Figure 2As shown, this includes a base station and a terminal. The base station sets SSB measurement configuration information for the terminal and sends this information to the terminal. After receiving the SSB measurement configuration information from the base station, the terminal performs SSB measurements based on the configuration information, obtains an SSB measurement report, and sends the report back to the base station via a first specified message. This first specified message is used to characterize contention resolution during random access, enabling the base station to configure a TCI state set for the terminal based on the SSB measurement report. The first specified message is as follows: Figure 3 Msg.3 in the middle.

[0214] As can be seen from the above embodiments, by receiving the SSB measurement configuration information sent by the base station, performing SSB measurement according to the SSB measurement configuration information, obtaining the SSB measurement report, and sending the SSB measurement report to the base station through the first designated message, the first designated message is a message used to characterize contention resolution during random access. In this way, the base station can configure the TCI state set for the terminal according to the SSB measurement report in the first designated message, thereby improving the efficiency of transmission configuration and reducing latency.

[0215] Figure 4 This is a flowchart illustrating another transmission configuration method according to an exemplary embodiment, which can be used by a terminal and is established on... Figure 1 Based on the method shown, such as Figure 4 As shown, the transmission configuration method may further include the following step 410:

[0216] In step 410, a second specified message (such as...) sent by the base station to indicate successful contention resolution is received. Figure 3 Msg.4 (as shown).

[0217] In this embodiment of the disclosure, in the second designated message, the base station sends a PDSCH (Physical Downlink Shared Channel) carrying a contention resolution flag to the terminal, and the terminal learns that random access was successful.

[0218] In one embodiment, during or after performing step 410, such as Figure 5 As shown, the transmission configuration method may further include the following step 510:

[0219] In step 510, the terminal receives RRC signaling sent by the base station. This RRC signaling includes a first TCI (Transmission Configuration Indication) state set configured by the base station for receiving the PDCCH (Physical Downlink Control Channel) and / or a second TCI state set for receiving the PDSCH. The first TCI state set includes a first correspondence between TCI state identifiers and SSB identifiers for receiving the PDCCH, and the second TCI state set includes a second correspondence between TCI state identifiers and SSB identifiers for receiving the PDSCH.

[0220] In this embodiment of the disclosure, the first correspondence may refer to the correspondence between the TCI status identifier and the SSB identifier used for receiving the PDCCH. Additionally, the QCL (quasi-co-addressable) type corresponding to the TCI status identifier used for receiving the PDCCH is type D, which is used for spatial Rx parameters, i.e., beam indication.

[0221] The second correspondence can refer to the correspondence between the TCI status identifier and the SSB identifier used for receiving PDSCH. Additionally, the QCL (quasi-co-addressable) type corresponding to the TCI status identifier used for receiving PDSCH is type D, which is used for spatial Rx parameters, i.e., beam indication.

[0222] Because the base station may send RRC signaling carrying the first TCI state set and / or the second TCI state set simultaneously with sending the second specified message; or it may send RRC signaling carrying the first TCI state set and / or the second TCI state set after sending the second specified message. Therefore, the terminal may receive RRC signaling carrying the first TCI state set and / or the second TCI state set simultaneously with receiving the second specified message; or it may receive RRC signaling carrying the first TCI state set and / or the second TCI state set after receiving the second specified message.

[0223] Furthermore, the first or second TCI state set configured by the base station for the terminal may include only one TCI state identifier or multiple TCI state identifiers. If only one TCI state identifier is included, the terminal can directly use the same receiving beam as the SSB identifier or the corresponding SSB when receiving the PDCCH or PDSCH. If multiple TCI state identifiers are included, the terminal also needs to receive the TCI state identifier that the base station reactivates or indicates when receiving the PDCCH or PDSCH (see [link to relevant documentation]). Figure 6 and Figure 7 (Example shown).

[0224] As can be seen from the above embodiments, at the same time or after receiving the second designated message sent by the base station to indicate the success of contention resolution, the RRC signaling sent by the base station is received. The RRC signaling includes a first TCI state set configured by the base station for receiving PDCCH and / or a second TCI state set configured by the base station for receiving PDSCH, thereby improving the reliability of receiving the TCI state set and avoiding delay.

[0225] Figure 6 This is a flowchart illustrating another transmission configuration method according to an exemplary embodiment, which can be used by a terminal and is established on... Figure 5 Based on the method shown, the first TCI state set includes at least two TCI state identifiers; such as Figure 6 As shown, the transmission configuration method may further include the following steps 610-630:

[0226] In step 610, the terminal receives a first MAC CE signaling sent by the base station. The first MAC CE signaling is used to activate a first TCI status identifier. The first TCI status identifier is a TCI status identifier selected by the base station from the first TCI status set, and is used by the terminal to determine the receive beam to be used when receiving the PDCCH from the base station.

[0227] In this embodiment of the disclosure, the first MAC CE signaling is used to activate the first TCI status identifier. For example, the first TCI status set includes 64 TCI status identifiers, and the base station can select one of these 64 TCI status identifiers as the first TCI status identifier.

[0228] In step 620, the first SSB identifier corresponding to the first TCI state identifier is determined according to the first correspondence relationship. The first correspondence relationship is located in the first TCI state set.

[0229] In step 630, when receiving the PDCCH, the same first receive beam as the SSB specified or corresponding to the first SSB identifier is used.

[0230] As can be seen from the above embodiments, by receiving the first MAC CE signaling sent by the base station, the first MAC CE signaling is used to activate the first TCI status identifier, which is selected by the base station from the first TCI status set. The base station determines the first SSB identifier corresponding to the first TCI status identifier according to the first correspondence relationship, and uses the same first receive beam as the SSB specified or corresponding to the first SSB identifier when receiving PDCCH, thereby realizing the transmission configuration for PDCCH reception and improving the reliability of the transmission configuration.

[0231] Figure 7 This is a flowchart illustrating another transmission configuration method according to an exemplary embodiment, which can be used by a terminal and is established on... Figure 5 Based on the method shown, the second TCI state set includes a first number of TCI state identifiers, where the first number is greater than 1; as shown Figure 7 As shown, the transmission configuration method may further include the following step 710:

[0232] In step 710, a second MAC CE signaling is received from the base station. The second MAC CE signaling is used to activate a second number of TCI status identifiers for PDSCH reception. The second number of TCI status identifiers are selected by the base station from a first number of TCI status identifiers in the second TCI status set.

[0233] In this embodiment of the disclosure, the second quantity is less than the first quantity. For example, if the first quantity is 64 and the second quantity is 8, for PDSCH, the base station can select 8 from the 64 TCI status identifiers and inform the terminal using the second MAC CE signaling.

[0234] As can be seen from the above embodiments, by receiving the second MAC CE signaling sent by the base station, the second MAC CE signaling is used to activate a second number of TCI status identifiers for PDSCH reception. The second number of TCI status identifiers are selected by the base station from the first number of TCI status identifiers, thereby realizing the transmission configuration for PDSCH reception and improving the reliability of the transmission configuration.

[0235] Figure 8 This is a flowchart illustrating another transmission configuration method according to an exemplary embodiment, which can be used by a terminal and is established on... Figure 7 Based on the method shown, the second quantity is greater than 1; such as Figure 8 As shown, the transmission configuration method may further include the following steps 810-830:

[0236] In step 810, the base station receives DCI (Downlink Control Information) signaling, which indicates a second TCI status identifier for PDSCH reception used for DCI signaling scheduling. The second TCI status identifier is a TCI status identifier selected by the base station from a second number of TCI status identifiers.

[0237] In this embodiment of the disclosure, the second quantity is greater than 1. For example, the second quantity is 8. The base station can select one of these 8 TCI status identifiers as the second TCI status identifier.

[0238] In step 820, the second SSB identifier corresponding to the second TCI state identifier is determined according to the second correspondence. The second correspondence is located within the second TCI state set.

[0239] In step 830, when receiving the PDSCH scheduled by the DCI signaling, the same second receive beam as the SSB specified or corresponding to the second SSB identifier is used.

[0240] As can be seen from the above embodiments, by receiving DCI signaling sent by the base station, the DCI signaling indicates a second TCI status identifier for PDSCH reception scheduled by the DCI signaling. The second TCI status identifier is a TCI status identifier selected by the base station from a second number of TCI status identifiers. The base station determines the second SSB identifier corresponding to the second TCI status identifier according to a second correspondence relationship. When receiving the PDSCH scheduled by the DCI signaling, the base station uses the same second receiving beam as the SSB specified or corresponding to the second SSB identifier. This realizes the transmission configuration for PDSCH reception scheduled by the DCI signaling and improves the reliability of the transmission configuration.

[0241] Figure 9 This is a flowchart illustrating a transmission configuration method according to an exemplary embodiment. This transmission configuration method can be used in a base station, such as... Figure 9 As shown, the transmission configuration method may include the following steps 910-930:

[0242] In step 910, configuration information for SSB measurement is set for the terminal.

[0243] In this embodiment of the disclosure, the SSB measurement configuration information may be configuration information configured by the base station for the terminal for SSB measurement.

[0244] In one embodiment, the SSB measurement configuration information includes:

[0245] (1-1) Measurement object, the measurement object including one or more SSBs specified by the base station;

[0246] (1-2) Measurement triggering conditions, wherein the measurement triggering conditions include a specified measurement triggering threshold value;

[0247] (1-3) Configuration of the measurement report, which includes specified content of the measurement report, or specified content of the measurement report and specified transmission resources of the measurement report. The specified transmission resources can be PUCCH or PUSCH resources.

[0248] In the above (1-3), the base station can configure specified transmission resources for the measurement report, or it can choose not to configure specified transmission resources. If not configured, the resources configured by the base station for the terminal for transmitting the first specified message (i.e., the message used to characterize contention resolution during random access (Msg.3)) can be directly reused. The resource used for transmitting Msg.3 can be a PUCCH or PUSCH resource.

[0249] In step 920, the SSB measurement configuration information is sent to the terminal so that the terminal can perform SSB measurement according to the SSB measurement configuration information and obtain an SSB measurement report.

[0250] In this embodiment of the disclosure, the base station can send a specified message to the terminal, for example, the specified message is a system message.

[0251] In one embodiment, step 920 can be implemented in the following way:

[0252] Add the SSB measurement configuration information to SIB1, and send SIB1 to the terminal.

[0253] In step 930, if an SSB measurement report is received from the terminal via a first specified message, where the first specified message is a message used to characterize contention resolution during random access, then a TCI state set is configured for the terminal based on the SSB measurement report.

[0254] For example, the base station determines a TCI state based on the SSB measurement report, such as TCI#0, which corresponds to SSB#i. Moreover, the QCL (Quasi-co-location) type corresponding to TCI#0 is type D. Type D is used for spatial Rxparameters, i.e., beam indication, as shown in the TCI state set in Table 1:

[0255]

[0256]

[0257] Table 1

[0258] In one embodiment, the TCI state set configured by the base station for the terminal may include a first TCI state set for receiving PDCCH and / or a second TCI state set for receiving PDSCH; when configuring the TCI state set for the terminal based on the SSB measurement report in step 930, the following implementation method can be adopted:

[0259] Based on the SSB measurement report, the terminal is configured with a first TCI state set for receiving PDCCH and / or a second TCI state set for receiving PDSCH. The first TCI state set includes a first correspondence between TCI state identifiers and SSB identifiers for receiving PDCCH, and the second TCI state set includes a second correspondence between TCI state identifiers and SSB identifiers for receiving PDSCH.

[0260] The first correspondence can refer to the correspondence between the TCI status identifier and the SSB identifier used for receiving PDCCH. Additionally, the QCL (quasi-co-addressable) type corresponding to the TCI status identifier used for receiving PDCCH is type D. This type D is used for spatial Rx parameters, i.e., beam indication, as shown in Table 1.

[0261] The second correspondence can refer to the correspondence between the TCI status identifier and the SSB identifier used for receiving PDSCH. Additionally, the QCL (quasi-co-addressable) type corresponding to the TCI status identifier used for receiving PDSCH is type D. This type D is used for spatial Rx parameters, i.e., beam indication, as shown in Table 1.

[0262] As can be seen from the above embodiments, after receiving the SSB measurement report sent by the terminal through the first specified message, the TCI state set can be configured for the terminal according to the SSB measurement report, thereby improving the efficiency of transmission configuration and reducing latency.

[0263] Figure 10 This is a flowchart illustrating another transmission configuration method according to an exemplary embodiment, which can be used for a base station and established on... Figure 9 Based on the method shown, such as Figure 10 As shown, the transmission configuration method may further include the following step 1010:

[0264] In step 1010, a second specified message (e.g., indicating successful resolution of the contention) is sent to the terminal. Figure 3 Msg.4 (as shown).

[0265] In one embodiment, during or after performing step 1010, such as Figure 11As shown, the transmission configuration method may further include the following step 1110:

[0266] In step 1110, the first TCI state set and / or the second TCI state set are added to the RRC signaling, and the RRC signaling is sent to the terminal.

[0267] As can be seen from the above embodiments, while or after sending the second specified message to the terminal to indicate the success of contention resolution, the first TCI state set and / or the second TCI state set can be added to the RRC signaling, and the RRC signaling can be sent to the terminal, thereby improving the reliability of transmitting the TCI state set and avoiding delay.

[0268] Figure 12 This is a flowchart illustrating another transmission configuration method according to an exemplary embodiment, which can be used for a base station and established on... Figure 11 Based on the method shown, the first TCI state set includes at least two TCI state identifiers; such as Figure 12 As shown, the transmission configuration method may further include the following steps 1210-1230:

[0269] In step 1210, a TCI state identifier is selected from the first TCI state set, and the selected TCI state identifier is the first TCI state identifier.

[0270] In step 1220, a first MAC CE signaling is generated. The first MAC CE signaling is used to activate a first TCI status identifier. The first TCI status identifier is used by the terminal to determine the receive beam to be used when receiving the PDCCH from the base station.

[0271] In step 1230, the first MAC CE signaling is sent to the terminal.

[0272] As can be seen from the above embodiments, by selecting a first TCI state identifier from the first TCI state set and activating the first TCI state identifier using the first MAC CE signaling, the terminal can receive PDCCH from the base station, thereby realizing the transmission configuration for PDCCH reception and improving the reliability of the transmission configuration.

[0274] In step 1310, a second number of TCI status identifiers for PDSCH reception are selected from a first number of TCI status identifiers in the second TCI status set.

[0275] In step 1320, a second MAC CE signaling is generated, which is used to activate a second number of TCI status identifiers for PDSCH reception.

[0276] In step 1330, the second MAC CE signaling is sent to the terminal.

[0277] As can be seen from the above embodiments, by selecting a second number of TCI status identifiers for PDSCH reception from a first number of TCI status identifiers and generating a second MAC CE signaling, the second MAC CE signaling is used to activate the second number of TCI status identifiers for PDSCH reception and to send the second MAC CE signaling to the terminal, thereby realizing the transmission configuration for PDSCH reception and improving the reliability of the transmission configuration.

[0278] Figure 14 This is a flowchart illustrating another transmission configuration method according to an exemplary embodiment, which can be used for a base station and established on... Figure 13 Based on the method shown, the second quantity is greater than 1; such as Figure 14 As shown, the transmission configuration method may further include the following steps 1410-1420:

[0279] In step 1410, DCI signaling is generated, which indicates a second TCI status identifier for PDSCH reception used for DCI signaling scheduling. The second TCI status identifier is a TCI status identifier selected by the base station from a second number of TCI status identifiers.

[0280] In step 1420, the DCI signaling is sent to the terminal.

[0281] As can be seen from the above embodiments, by generating DCI signaling, which indicates a second TCI status identifier for PDSCH reception used for DCI signaling scheduling, and the second TCI status identifier is a TCI status identifier selected by the base station from a second number of TCI status identifiers, and by sending DCI signaling to the terminal, the transmission configuration for PDSCH reception used for DCI signaling scheduling is realized, and the reliability of the transmission configuration is also improved.
