Abstract
Description
Indication method, device, terminal and network side equipment of configuration information
[0001] The present disclosure claims priority to the Chinese patent application No. 202411090360.5, filed on August 9, 2024, and entitled "Indication method, device, terminal and network side equipment of configuration information", the whole content of which is incorporated herein by reference. TECHNICAL FIELD
[0002] The present disclosure relates to the technical field of communication, and in particular to an indication method, device, terminal and network side equipment of configuration information. BACKGROUND
[0003] In the existing New Radio (NR) system, the base station needs to periodically send / receive the common signal (or channel) configuration to ensure the normal work of the terminal under network coverage. The existing common signal (or channel) is indicated by the parameters in the System Information Block 1 (SIB1), and can only be updated by the SIB1 update method.
[0004] In order to achieve the effect of network energy saving, it is proposed to realize the self-adaptation of the common signal from the time domain. That is, when the traffic is small, the base station uses a relatively sparse common signal configuration for transmission and reception, so that the base station has time to enter the sleep state, thereby achieving the effect of energy saving. When the traffic increases, the base station will use a dense common signal configuration for transmission and reception, so that the base station can guarantee the normal quality of service.
[0005] In the prior art, if the paging downlink control information (DCI) is used to indicate the self-adaptation of the common signal, the same paging occasion (PO) corresponds to the legacy user equipment (UE) and the Rel-19 network energy saving (NES) UE. If the existing indication method is used, the legacy UE also needs to receive this notification, which causes the legacy UE to perform a SIB update procedure but does not receive any updated information, resulting in waste of network resources.

[0272] The technical solutions in the embodiments of the present disclosure will be described clearly and completely in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.
[0273] In the description of the embodiments of the present disclosure, some concepts used in the following description are first explained.
[0274] I. System information change indication
[0275] The system information change indication can be used to update the system information except SIB6, SIB7, SIB8 and posSIBs. The update of the system information only occurs on the frame satisfying the modification period (MP), which contains the product of the modification period coefficient (modificationPeriodCoeff) and the default paging cycle (defaultPagingCycle), such as modificationPeriodCoeff*defaultPagingCycle, wherein modificationPeriodCoeff can be configured as {n2, n4, n8, n16}, and defaultPagingCycle is the paging cycle configured in SIB1.
[0276] The system information can be transmitted multiple times within one MP, but the content of the system information cannot be changed within one MP. As shown in FIG. 1, when the system information of the cell changes, the base station notifies the UE that the system information changes in MP0, and sends the updated system information in the next MP, i.e. MP1.
[0277] For each UE, the UE needs to monitor the corresponding PO in MP0 first to paging DCI, which indicates system information update. Then the UE monitors DCI 1-0 in MP1 to receive updated system information.
[0278] II. Paging DCI (Paging DCI)
[0279] The paging DCI contains a short message indicator, which is used to indicate the different purposes of the paging DCI. For example: when the short message = 11, the paging DCI can be used for paging scheduling information, phase tracking reference signal (TRS) availability indication and short massage indication, at this time the UE needs to decode all bit fields in the paging DCI, the reserved bit may be 0. The 5-8 bits in the short message are not used, and the legacy UE will ignore this indication information after receiving. Among them, the Short Message indicator is shown in Table 1, and the Short Messages are shown in Table 2.
[0280] Table 1: Short Message indicator
[0281] Table 2: Short Messages
[0282] III. Common signal related
[0283] (1) SSB periodicity configuration, when the terminal obtains SSB through cell search, obtains the Master Information Block (MIB) parameters and SIB1 reception configuration information based on the Physical broadcast channel (PBCH) in the SSB, then listens to the DCI 1_0 added by SI-RNTI based on the SIB1 reception configuration, and then obtains the SIB1 parameter information. The terminal obtains the actual period of SSB through the SSB periodicity serving cell parameter (ssb-PeriodicityServingCell) in SIB1. The candidate values of ssb-PeriodicityServingCell are, for example, 5ms, 10ms, 20ms, 40ms, 80ms and 160ms. Because the terminal assumes the default period of SSB to be 20ms in the cell search process, the SSB period on the cell supporting cell search is usually 20ms, and the SSB period can also be extended to 40ms, 80ms or 160ms, which will have different degrees of network energy saving gain.
[0284] (2) PRACH periodicity configuration, for Radio Resource Control (RRC) idle state (RRC_IDLE) / inactive state (INACTIVE) UE, the time domain location of PRACH resource can be configured through prach-ConfigurationIndex in SIB1, and the period of the radio frame where the PRACH resource is located is 10ms, 20ms, 40ms or 80ms. For RRC_CONNECTED UE, the time domain location of PRACH resource can be configured through high layer parameter prach-ConfigurationIndex or msgA-PRACH-ConfigurationIndex. Among them, the resource information indicated by prach-ConfigurationIndex or msgA-PRACH-ConfigurationIndex is shown in Table 3.
[0285] Table 3: Resource information indicated by prach-ConfigurationIndex or msgA-PRACH-ConfigurationIndex
[0286] (3) PO resource location determination method, for RRC_IDLE / INACTIVE UE, the monitoring opportunity (MO) resource location of PO is determined according to the broadcast information in SIB1, wherein the value of DRX cycle is the minimum value in the UE-specific (specific) discontinuous reception (DRX) cycle configured by high-layer signaling (RRC signaling and / or core network signaling) and the default DRX cycle of system message broadcast, and the unit is radio frame.
[0287] Embodiments of the present disclosure provide a configuration information indication method and device, and a terminal and network side equipment, to solve the problem of resource waste when updating common signal (or channel) configuration.
[0288] The method and device are based on the same application concept, and since the principles of the method and device for solving the problem are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.
[0289] As shown in FIG. 2, embodiments of the present disclosure provide a configuration information indication method applied to a terminal, specifically including the following steps:
[0290] Step 201, the terminal receives a first downlink control information (DCI), the first DCI includes a first information field, and the first information field is used to indicate one of the following:
[0291] The signal configuration information is updated;
[0292] The related information of the signal configuration information.
[0293] In this embodiment, a dedicated information field related to configuration information update is defined in the first DCI, which is used to indicate that the signal configuration is updated or to indicate the updated signal configuration information. The first information field can be an existing but unused information field in the first DCI, or a newly added information field.
[0294] Wherein, if the first information field indicates that the signal configuration information is updated, the terminal can determine that the signal configuration information is updated by decoding the first information field after receiving the first DCI, and can determine whether to receive the updated signal configuration information according to the requirement.
[0295] The first information field can also directly indicate the related information of the signal configuration information, for example, the first information field directly indicates the index of the updated signal configuration information, or indicates the activated signal configuration information, or indicates the deactivated signal configuration information. The terminal can determine whether the signal configuration information is updated according to the indication of the first information field, and can determine the updated signal configuration information.
[0296] In some embodiments, the first information field can be pre-configured, and the terminal and the network side device can know the location of the first information field for indicating the signal configuration information update and / or the related information of the signal configuration information. In some embodiments, the terminal is a terminal with network energy saving (NES) capability, which has the capability of decoding the first information field, and can also be understood as the first information field being associated with the terminal, and only NES UE can decode the first information field. For example, if the network side device configures the terminal with the first information field related parameters, and the UE has the capability of decoding the first information field, the UE can obtain the indication content of the first information field after receiving the first DCI. The legacy UE does not have the capability of decoding the first information field and / or the network side device does not configure the legacy UE with the first information field related parameters, and the legacy UE ignores the first information field after receiving the first DCI.
[0297] The signal configuration information is related information for ensuring the normal work of the terminal under network coverage. In some embodiments, the signal configuration information includes at least one of the following:
[0298] 1) Physical random access channel (PRACH) configuration information; the signal configuration information can include: PRACH configuration parameters configured for terminals with network energy saving capability, or additional PRACH configuration parameters, such as additional PRACH configuration, additional PRACH configuration index, additional parameters for determining PRACH time domain and / or frequency domain resources, etc.
[0299] 2) Paging configuration information; the signal configuration information includes paging parameters or additional paging parameters configured for terminals with network energy saving capability, such as paging cycle, paging frame number, paging occasion number, etc.
[0300] 3) Synchronization signal block (SSB) configuration information. The signal configuration information includes SSB parameters configured for terminals with network energy saving capability, such as SSB cycle, SSB position in burst, etc.
[0301] In the embodiments of the present disclosure, a first information field is defined in the first DCI, which is specially used for indicating the signal configuration information update or the related information of the signal configuration information. The terminal can obtain the content of the signal configuration information indicated by the first information field by decoding the first information field after receiving the first DCI. Other terminals do not have the capability of decoding the first information field, and can ignore the information, thereby avoiding resource waste.
[0302] In some embodiments, in the embodiments of the present disclosure, the first DCI can also be replaced by a Medium Access Control (MAC) Control Element (CE), the MAC CE including the first information field, the first information field being used to indicate at least one of the following: signal configuration information is updated; related information of signal configuration information. Adding the first information field in the MCE CE indicates the signal configuration information applied by the current carrier or other carriers.
[0303] As an optional embodiment, the method further comprises:
[0304] If the first information field indicates that the signal configuration information is updated, the second DCI for scheduling the signal configuration information is received starting from the first time domain position; and the updated signal configuration information is received according to the second DCI.
[0305] In this embodiment, the terminal receives the first DCI, and if the first information field in the first DCI indicates that the signal configuration information is updated, the terminal can start to listen to and receive the second DCI starting from the first time domain position, the second DCI being used to schedule the updated signal configuration information.
[0306] The first time domain position is a pre-configured or pre-defined position, and after the terminal determines that the signal configuration information is updated according to the first DCI, the terminal can start to listen to the second DCI and receive the updated signal configuration information starting from the first time domain position. The updated signal configuration information can be carried by system information, for example, by SIB1 or a new SIB26.
[0307] In some embodiments, the first DCI can be a paging DCI, and the first information field can be a certain bit field in a short message field in the paging DCI, for example, the a-th bit in the short message field which is not used, the optional bit position a being {5, 6, 7, 8}.
[0308] The first information field can indicate that the signal configuration information is updated by a bit value, for example: if the N-th bit in the short message field in the paging DCI is set to "1", it indicates that the signal configuration information is updated. If the N-th bit in the short message field in the paging DCI is set to "0", it indicates that the signal configuration information is not updated, or the UE can ignore this indication.
[0309] In some embodiments, the first information field is only used to indicate the terminal having network energy saving capability, and / or the terminal configured with the parameters related to the first information field, and / or the terminal having the capability of decoding the first information field. If the terminal is another terminal (such as a legacy UE), the indication field can be ignored.
[0310] As an optional embodiment, the first time domain position comprises one of the following:
[0311] (1) a time domain position corresponding to a frame boundary of a first period in which the first DCI is located;
[0312] In some embodiments, the length of the first period is N times the length of a paging cycle.
[0313] Wherein, the value of N is multiplexed with the value of modificationPeriodCoeff, or the value of N is configured by the network side device, or the value of N is predefined.
[0314] In this embodiment, the first time domain position can be a frame boundary of the first period in which the first DCI is located. For example, in the case that the terminal receives the first DCI and the first information field in the first DCI indicates that the signal configuration information is updated, the terminal can start monitoring the second DCI at the frame boundary of the first period and receive the updated signal configuration information.
[0315] Wherein, the first period is a pre-configured or pre-defined period, and the length of the first period can be N* paging cycle, wherein paging cycle is a paging cycle provided by system information. N can be multiplexed as a parameter modificationPeriodCoeff configured by system information; or the network side device separately configures N, for example: the value range of N is configured as {2, 4, 8, 16}, or the value range of N is configured as {1, 2, 4, 8, 16}, or the value range of N is configured as {1, 2, 3, 4}. N can also be a predefined parameter, for example, the default value is 1 or 2.
[0316] In some embodiments, if the network side device configures the parameter N, the terminal can determine the length of the first period by applying the parameter N configured by the network side; otherwise, the terminal determines the length of the first period by multiplexing modificationPeriodCoeff or a predefined N value.
[0317] In this embodiment, after the terminal receives the first DCI, if the first information field indicates that the signal configuration information is updated, the terminal can receive the second DCI at the frame boundary of the first period in which the first DCI is located, and receive the updated signal configuration information based on the second DCI.
[0318] (2) a position X slots after the first DCI;
[0319] In this embodiment, the terminal can start receiving the second DCI at a position X time slots after the first DCI, for example, the first time domain position is slot n+X, where slot n is the time slot position at which the UE receives the first DCI, and X can be a number of time slots that is protocol default or configured by a higher layer.
[0320] In some embodiments, the second DCI includes at least one of the following:
[0321] 1) a DCI scrambled by a system information radio network temporary identifier (SI-RNTI), the SI-RNTI-scrambled DCI including a second information field used to indicate that the second DCI is used to schedule updated signal configuration information;
[0322] 2) a DCI scrambled by another RNTI, the other RNTI-scrambled DCI being used to schedule updated signal configuration information.
[0323] In this embodiment, the terminal determines, according to the first information field of the first DCI, that the signal configuration information is updated, and starts monitoring the second DCI at a first time domain position, which can be a DCI 1_0 scrambled by a SI-RNTI. For example, M bits are introduced in the DCI 1_0, which are used to indicate that the DCI 1_0 is used to schedule updated signal configuration information.
[0324] The second DCI can also be a DCI scrambled by another RNTI (such as a new RNTI), for example, a DCI 1_0 scrambled by a NES-RNTI. In this case, the second DCI can include one or more of time domain indication signaling, frequency domain indication signaling, VRB-to-PRB mapping, modulation and coding scheme (MCS) indication field, RV field, and reserved bits.
[0325] In some embodiments, after the terminal receives the DCI, the terminal can receive the updated signal configuration information in a next period of the first period.
[0326] As an optional embodiment, if the first information field is used to indicate information related to the signal configuration information, the updated signal configuration information takes effect at a second time domain position.
[0327] The information related to the signal configuration information includes at least one of the following:
[0328] an index corresponding to the updated signal configuration information;
[0329] activation of the signal configuration information;
[0330] deactivation of the signal configuration information.
[0331] In this embodiment, the terminal receives the first DCI, and if the first information field of the first DCI indicates the related information of the signal configuration information, for example, indicates the index corresponding to the updated signal configuration information, it is considered that the updated signal configuration information takes effect at the second time domain position, and it can also be understood that the terminal can start using the updated signal configuration information at the second time domain position.
[0332] In some embodiments, the method further comprises: receiving M signal configuration information sent by the network side device, M is greater than or equal to 1; wherein, when M is greater than or equal to 2, each signal configuration information has a corresponding index.
[0333] In this embodiment, the network side device can pre-configure one or more signal configuration information as candidates for the terminal. Wherein, if multiple signal configuration information is configured, each signal configuration information has a corresponding index (or number). When the network side device sends the first DCI, it can directly indicate the index of the updated signal configuration information in the first information field, and then the terminal can determine the updated signal configuration information according to the index.
[0334] Alternatively, the first information field can directly indicate the activated signal configuration information, and the terminal considers that the activated signal configuration information is the updated signal configuration information. Alternatively, the first information field can also directly indicate the activation or deactivation state, for example, the network side device only pre-configures one signal configuration information as a candidate, and can indicate activation in the first information field of the first DCI, so that the terminal determines that the pre-configured one signal configuration information is activated, and the signal configuration information is the updated signal configuration information; or, the network side device indicates deactivation in the first information field of the first DCI, so that the terminal determines that the current signal configuration information is deactivated, and the pre-configured one signal configuration information is the updated signal configuration information.
[0335] In some embodiments, the second time domain position includes one of the following:
[0336] (1) the time domain position corresponding to the frame boundary of the first period in which the first DCI is located;
[0337] In some embodiments, the length of the first period is N times the length of the paging period.
[0338] Wherein, the value of N is the value of modificationPeriodCoeff, or the value of N is configured by the network side device, or the value of N is predefined.
[0339] In this embodiment, the second time domain position can be a frame boundary of the first period in which the first DCI is located. For example, the terminal receives the first DCI, and the first information field in the first DCI indicates the index of the updated signal configuration information. The terminal determines that the updated signal configuration information takes effect at the frame boundary of the first period, which can also be understood as starting to use the updated signal configuration information at the frame boundary of the first period. The determination method of the length of the first period is not described here.
[0340] (2) a position of X time slots after the first DCI;
[0341] For example, the terminal receives the first DCI, and the first information field in the first DCI indicates the index of the updated signal configuration information. The terminal determines that the updated signal configuration information takes effect at the position of X time slots after the first DCI, which can also be understood as starting to use the updated signal configuration information at the position of X time slots after the first DCI.
[0342] For example, the second time domain position is slot n+X, where slot n is the time slot position at which the UE receives the first DCI, and X can be a time slot number that is protocol default or high-layer configured.
[0343] (3) a position of Y time slots after a feedback time slot corresponding to the first DCI; where X and Y are positive integers.
[0344] In this embodiment, the feedback time slot corresponding to the first DCI is, for example, an Acknowledgment (ACK) / Negative Acknowledgment (NACK) feedback time slot corresponding to the first DCI. For example, the terminal receives the first DCI, and the first information field in the first DCI indicates the index of the updated signal configuration information. The terminal determines that the updated signal configuration information takes effect at the position of Y time slots after the ACK / NACK feedback time slot corresponding to the first DCI, which can also be understood as starting to use the updated signal configuration information at the position of Y time slots after the ACK / NACK feedback time slot corresponding to the first DCI.
[0345] In some embodiments, the first time domain position or the second time domain position includes one of the following:
[0346] a time domain position corresponding to a frame boundary of a first period in which the first DCI is located;
[0347] a position of X time slots after the first DCI;
[0348] a position of Y time slots after a feedback time slot corresponding to the first DCI;
[0349] wherein X, Y are positive integers.
[0350] In some embodiments, in a case where the updated signal configuration information is a subset of the pre-updated signal configuration information, the first time domain position or the second time domain position is a time domain position corresponding to a frame boundary of a first period in which the first DCI is located.
[0351] or,
[0352] In a case where the pre-updated signal configuration information is a subset of the updated signal configuration information, the first time domain position or the second time domain position is: a position of X slots after the first DCI, or a position of Y slots after a feedback slot corresponding to the first DCI.
[0353] In some embodiments, the first DCI can be a paging DCI, and the first information field can be a certain bit field in a short message field in the paging DCI, for example, the a-th bit in the short message which is not used, and the optional bit position a is {5, 6, 7, 8}. For example: for the case of pre-configuring one signal configuration information as a candidate, the 5th bit information is used, and setting to 1 represents that the pre-configured signal configuration information is activated, and setting to 0 represents that the pre-configured signal configuration information is deactivated. For another example: the 5th-6th bit information is used to indicate the index (or number) of the signal configuration information, wherein 00 represents no adaptive signal configuration information, 01 represents signal configuration information number 1, 10 represents signal configuration information number 2, and so on. The updated signal configuration information is indicated by the number.
[0354] As an optional embodiment, the receiving the first DCI comprises:
[0355] receiving the first DCI in a first period;
[0356] wherein, in a case where the length of the first period is less than the length of the system information update period, the first DCI is received at least once in each of the first periods.
[0357] In this embodiment, the terminal can receive the first DCI in a first period, and the length of the first period is N times the length of the paging period; wherein the value of N multiplexes the value of the system information update period coefficient, or the value of N is configured by the network side device, or the value of N is predefined.
[0358] For example: when the length of the first period is less than the length of the system information update period, the RRC_CONNECTED UE needs to listen to the paging information (i.e. the first DCI) at least once in each first period.
[0359] In some embodiments, the first DCI comprises at least one of:
[0360] 1) a paging DCI;
[0361] 2) a terminal-specific single-carrier scheduling DCI; for example, DCI 1_1 / DCI 1_2;
[0362] 3) a terminal-specific multi-carrier scheduling DCI; for example, DCI 1_3;
[0363] 4) a group-common DCI, for example, DCI 2_X.
[0364] In this embodiment, the first DCI can be a paging DCI, or can be other DCI, for example, the network side device can set the first information field in the paging DCI, or can set the first information field in other DCI, for indicating that the signal configuration information is updated or indicating the related information of the signal configuration information. In some embodiments, the network side device can also send multiple different types of DCI in one period for indicating that the signal configuration information is updated or indicating the related information of the signal configuration information.
[0365] In some embodiments, the first information field comprises:
[0366] In the case where the first DCI is a paging DCI, the first information field is X bits in the short message field, X is greater than or equal to 1;
[0367] Or,
[0368] In the case where the first DCI is other DCI than the paging DCI, the first information field is a newly added information field.
[0369] In this embodiment, if the first DCI is a paging DCI, multiple bits in the "short message" field in the paging DCI can be used as the first information field, for example, the 5th-8th bits in the short message field are used as the first information field to indicate that the signal configuration information is updated and / or the related information of the signal configuration information. For example: the a-th bit of the short message field in the paging DCI is used to indicate that the signal configuration information is updated, a optional bit position is {5, 6, 7, 8}, for example, the a-th bit is set to "1" to indicate that the signal configuration information is updated. Set to "0" indicates that the signal configuration information is not updated, or the UE can ignore this indication.
[0370] For example, the b bits in the 5-8 bits of the short message field in the paging DCI are used to indicate the number of the signal configuration information, or the activation / deactivation of the signal configuration information. For example, the 5th bit is set to 1 to represent the activation of the signal configuration information, and set to 0 to represent the deactivation of the signal configuration information.
[0371] If the first DCI is other than the paging DCI, such as terminal-specific single-carrier scheduling DCI, terminal-specific multi-carrier scheduling DCI, group-common DCI, etc., the signal configuration information update can be indicated by adding a new information field.
[0372] As an optional embodiment, if the first information field is used to indicate the index of the updated signal configuration information, the length of the first information field is determined according to the number of the signal configuration information.
[0373] Alternatively,
[0374] If the first information field is used to indicate the activation or deactivation of the signal configuration information, the length of the first information field is 1 bit.
[0375] Alternatively,
[0376] The length of the first information field is determined according to the high-level parameter configuration.
[0377] For example, the first DCI is terminal-specific single-carrier scheduling DCI, such as DCI 1_1 / DCI 1_2, and an M-bit first information field is added in the DCI. If the M bits are used to indicate the number of the updated signal configuration information, M can be determined according to the high-level configuration parameter, M=log_2(N+1), N is the number of signal configuration information configured by the network side device. If the M bits indicate the activation or deactivation of the signal configuration information, M=1.
[0378] For example, the first DCI is terminal-specific multi-carrier scheduling DCI, such as DCI 1_3, and a first information field is added in the DCI. For example, if each carrier CC corresponding to the first information field in the DCI 1_3 is corresponding to a first information field, the length of each CC corresponding to the first information field can be determined according to the content of the indication. For example, if the first information field is used to indicate the number of the updated signal configuration information, the length (M) of the first information field can be determined according to the high-level configuration parameter, M=log_2(N+1), N is the number of signal configuration information configured by the network side device. If the first information field indicates the activation or deactivation of the signal configuration information, M=1. If all the CCs scheduled by the DCI 1_3 correspond to a first information field, the first information field is a label in the high-level parameter configuration list, and the UE determines the signal configuration information corresponding to the label according to the high-level parameter configuration list.
[0379] For example, the first DCI is a group common DCI, such as DCI 2_X, and a first information field is added in the DCI. If a high layer configuration parameter (e.g., nesToAddModList) is provided, a service cell identity (ID) indicated by each cell is provided, and / or a starting bit position corresponding to the service cell is provided, and / or signal configuration information corresponding to the service cell is provided, i.e., the high layer configuration parameter provides {service cell ID, starting bit position, signal configuration information}. The length of the first information field corresponding to each service cell is determined according to the length of the first information field in the DCI is determined
[0380] If the high layer configuration parameter is the starting bit position of the service cell configuration in the DCI, i.e., each cell provides the starting position of the information block indicated by the corresponding information block, for each information block, 1 bit is used to indicate the activation or deactivation of the signal configuration information according to the protocol, and / or parameters for other purposes. This 1 bit can be placed at the beginning or the end of the information block. Alternatively, the length of the first information field in each information block and the corresponding indication information are determined by other configuration parameters.
[0381] As an optional embodiment, if the first DCI received by the terminal in the first period includes a paging DCI and a DCI other than the paging DCI, the signal configuration information satisfies a first condition;
[0382] The first condition includes one of the following:
[0383] The related information of the signal configuration information indicated by the paging DCI is the same as the related information of the signal configuration information indicated by the other DCI;
[0384] If the related information of the signal configuration information indicated by the paging DCI is different from the related information of the signal configuration information indicated by the other DCI, the related information of the signal configuration information indicated by the latest received DCI is valid;
[0385] If the related information of the signal configuration information indicated by the paging DCI is different from the related information of the signal configuration information indicated by the other DCI, the related information of the signal configuration information indicated by the paging DCI is valid;
[0386] If the related information of the signal configuration information indicated by the paging DCI is different from the related information of the signal configuration information indicated by the other DCI, the related information of the signal configuration information indicated by the other DCI is valid.
[0387] In this embodiment, if the terminal receives different types of DCI at the same time in the first period, such as paging DCI and terminal-specific single-carrier scheduling DCI, paging DCI and terminal-specific single-multiple-carrier scheduling DCI, paging DCI and group-common DCI, and the signal configuration information indicated by the two types of DCI is the same, it can also be understood that the UE does not expect to receive the signal configuration information indicated by the DCI scrambled by the P-RNTI and the DCI 1_1 / DCI 1_2 / DCI 1_3 / group-common DCI at the same time in the same first period to be different.
[0388] Alternatively, if the terminal receives different types of DCI at the same time in the first period, such as when the UE receives the signal configuration information indicated by the DCI scrambled by the P-RNTI and the DCI 1_1 / DCI 1_2 / DCI 1_3 / group-common DCI at the same time in the same first period to be different, the signal configuration information of the UE is determined according to the latest received DCI, or according to the DCI scrambled by the P-RNTI, or according to the DCI 1_1 / DCI 1_2 / DCI 1_3 / group-common DCI. The specific determination method can be pre-configured or pre-defined.
[0389] In some embodiments, in the embodiments of the present disclosure, if the terminal is an RRC idle state UE (RRC_IDLE UE) or a non-active state UE, the network side device can indicate the related information of the signal configuration information by adding a first information field in the paging DCI, that is, the UE in this case can obtain the update of the signal configuration information according to the first information field. If the terminal is an RRC connected state UE (RRC_CONNECTED UE), the network side device can indicate the related information of the signal configuration information by adding a first information field in other DCI.
[0390] The implementation process of the indication method of the configuration information of the embodiments of the present disclosure is illustrated below.
[0391] Example one, taking the indication of signal configuration information update through SIB1 as an example, illustrates the indication method of signal configuration information and the determination method of application time.
[0392] It is assumed that the common signal configuration for energy-saving UEs, i.e. the signal configuration information, is included in SIB1. For "signal configuration information", one or more of the following is included:
[0393] PRACH configuration, including parameters for configuring cell-level random access parameters, such as time-domain related parameters of PRACH and / or frequency-domain related parameters of PRACH;
[0394] Paging configuration, including parameters for configuring cell level paging, such as paging time domain related configuration parameters, including: paging cycle, and / or the number of paging subframes, and / or the number of POs in a PF;
[0395] SSB configuration, including parameters for configuring SSB, such as: SSB cycle, and / or SSB burst position parameters, etc.
[0396] Assuming that the base station transmits / receives common signals according to signal configuration information for energy-saving UEs and signal configuration information for non-energy-saving UEs, when the base station finds that the network traffic decreases or the number of UEs decreases, the base station notifies the energy-saving UEs in the cell range to deactivate or update the current first signal configuration information to other second signal configuration information through SIB1. The base station transmits paging DCI to indicate that the signal configuration information in SIB1 has changed, and transmits the second DCI to schedule SIB1 in the first time domain position.
[0397] The specific process is shown in FIG. 3: the base station transmits paging DCI (such as first DCI), and UE1 receives paging DCI (such as first DCI) on the corresponding PO. Among them, the Nth bit in the short message field in the paging DCI, N optional bit position is {5, 6, 7, 8} is used to indicate whether the signal configuration information is updated. For example, the protocol can stipulate that the 5th bit in the short message is used to indicate whether the signal configuration information is updated, if the bit is set to 1, it indicates “update”, if the bit is set to 0, it indicates “no update”.
[0398] It should be noted that the signal configuration information update does not trigger the traditional SI update process, that is, the first bit in the short message field in the paging DCI will not be set to “1” as a result.
[0399] The base station transmits a signal configuration information update indication on the PO in the first cycle 0, until the first time domain position t1, the base station starts to transmit SIB1 including the updated configuration of the signal configuration information and starts to apply the updated signal configuration information. UE1 starts to monitor the second DCI after the first time domain position t1, and receives SIB1 including the updated signal configuration information.
[0400] Specifically, the first time domain position t1 is the frame boundary of the first cycle 0 where the first DCI is located, and the length of the first cycle = N* paging cycle has the following several determination methods:
[0401] Candidate method 1: the length of the first cycle is the BCCH modification cycle length in the system information update configuration in the protocol, that is, the value of N is determined according to the modificationPeriodCoeff in the BCCH configuration.
[0402] Candidate method 2: the length of the first period is determined according to the first period configuration parameter N1 of the system information, which can be the same as or different from the N value configured by the BCCH. The value range of N can be {2, 4, 8, 16}, or {1, 2, 4, 8, 16}, or {1, 2, 3, 4}.
[0403] Candidate method 3: the length of the first period is N paging periods by default, for example, 1 paging period or 2 paging periods by default.
[0404] Candidate method 4: the first period configuration parameter N1 is a selected configuration parameter. If the base station provides the configuration of the first period configuration parameter N1, the length of the first period is determined according to the candidate method 2; if the base station does not provide the configuration of the first period configuration parameter N1, the length of the first period is determined according to the candidate method 1.
[0405] Candidate method 5: the first period configuration parameter N1 is a selected configuration parameter. If the base station provides the configuration of the first period configuration parameter N1, the length of the first period is determined according to the candidate method 2; if the base station does not provide the configuration information of the first period configuration parameter N1, the length of the first period is determined according to the candidate method 3.
[0406] In addition, when the length of the first period is less than the system information update period, the RRC_CONNECTED UE needs to listen to the paging information at least once in each first period. That is, when the length of the first period is less than the system information update period, the length of the first period has higher priority.
[0407] In some embodiments, the second DCI includes one of:
[0408] (1) When UE1 receives the DCI 1_0 scrambled by SI-RNTI and the system information indication field is set to 0, UE1 receives and decodes the signal configuration information in the SIB1 scheduled by this DCI.
[0409] (2) A second information field is added in the DCI 1_0 scrambled by SI-RNTI to indicate that the scheduled information is the updated signal configuration information. For example: when the second information field is 1, UE1 obtains the scheduled information as the updated signal configuration information.
[0410] (3) A DCI 1_0 scrambled by a new RNTI, for example, a DCI 1_0 scrambled by NES-RNTI, is introduced to indicate that the scheduled information is the updated signal configuration information. The information field in this DCI can include one or more of the following: time domain indication signaling, frequency domain indication signaling, VRB-to-PRB mapping, MCS indication field, RV field, and reserved bits.
[0411] In this embodiment, after the terminal receives the paging DCI, it can determine that the signal configuration information is updated according to the short message field in the paging DCI, then receives the second DCI at the first time domain position, and receives the SIB1 including the updated signal configuration information according to the second DCI. By setting the indication field for indicating the signal configuration information update in the paging DCI, the terminal can obtain the signal configuration information based on its own capability.
[0412] Example two, based on SIBX, indicating that the signal configuration information is updated.
[0413] This embodiment takes SIBX, for example, SIB26, as an example to indicate the signal configuration information update, and explains the indication method of the signal configuration information and the determination method of the application time.
[0414] It is assumed that the common signal configuration for energy-saving UEs, i.e. the signal configuration information, is included in SIB26. The signal configuration information includes one or more of the following:
[0415] PRACH configuration, including parameters for configuring cell-level random access, such as time-domain related parameters of PRACH and / or frequency-domain related parameters of PRACH;
[0416] Paging configuration, including parameters for configuring cell-level paging, such as paging time-domain related configuration parameters, including: paging cycle, and / or number of paging subframes, and / or number of POs in one PF;
[0417] SSB configuration, including parameters for configuring SSB, such as: SSB cycle, and / or SSB burst position parameters, etc.
[0418] UE1 determines the signal configuration information based on the configuration of the common signal in SIB1 and SIB26, such as the configuration of SSB, PRACH and paging message. The content of the signal configuration information in SIB1 can use traditional technology, and it is within the protection scope of the present disclosure to provide additional signal configuration information for UEs through SIB26.
[0419] When the signal configuration information provided by SIB26 in the network changes, the base station sends the paging DCI (such as the first DCI) to indicate that the signal configuration information in SIBX changes, and sends the second DCI to schedule SIB1 after the first time domain position.
[0420] The specific process is shown in FIG. 4: the base station sends a paging DCI (such as the first DCI), and UE1 receives the paging DCI (such as the first DCI) on the corresponding PO. Among them, the Nth bit in the short message field in the paging DCI, N optional bit positions are {5, 6, 7, 8}, which are used to indicate whether the signal configuration information in SIB26 is updated. For example: it can be stipulated that the 5th bit in the short message field is used to indicate whether the signal configuration information in SIB26 is updated, and if this bit is set to 1, it indicates "update", and if it is set to 0, it indicates "no update".
[0421] The base station sends a signal configuration information update indication on the PO in the first cycle 0 until the first time domain position t1, and the base station starts to send SIB26 including the updated configuration of the signal configuration information and starts to apply the updated signal configuration information. UE1 starts to monitor the second DCI after the first time domain position t1, and receives SIB1 including the updated signal configuration information.
[0422] In some embodiments, the first time domain position t1 is the frame boundary of the first cycle (i.e. the first cycle 0 in FIG. 4) where the paging DCI is located, and the length of the first cycle = N* paging cycle has the following determination methods:
[0423] Candidate method 1: the length of the first cycle is the BCCH modification cycle length in the system information update configuration in the multiplexing protocol, that is, the value of N is determined according to the modificationPeriodCoeff in the BCCH configuration.
[0424] Candidate method 2: the length of the first cycle is determined according to the first cycle configuration parameter N1 of the system information, and this N1 can be the same as or different from the value of N in the BCCH configuration. The value range of N can be {2, 4, 8, 16}, or {1, 2, 4, 8, 16}, or {1, 2, 3, 4}.
[0425] Candidate method 3: the length of the first cycle is defaulted to N paging cycles, for example, defaulted to 1 paging cycle or 2 paging cycles.
[0426] Candidate method 4: the first cycle configuration parameter N1 is a selected configuration parameter. If the base station provides configuration information of the first cycle configuration parameter N1, the length of the first cycle is determined according to candidate method 2; if the base station does not provide configuration information of the cycle configuration parameter N1, the length of the first cycle is determined according to candidate method 1.
[0427] Candidate method 5: the first cycle configuration parameter N1 is a selected configuration parameter. If the base station provides the configuration of the first cycle configuration parameter N1, the length of the first cycle is determined according to candidate method 2; if the base station does not provide the configuration of the cycle configuration parameter N1, the length of the first cycle is determined according to candidate method 3.
[0428] In addition, when the length of the first cycle is less than the system information update cycle, the RRC_CONNECTED UE needs to listen to the paging information at least once in each first cycle. That is, when the length of the first cycle is less than the system information update cycle, the length of the first cycle has higher priority.
[0429] In some embodiments, the second DCI includes:
[0430] (1) When UE1 receives the DCI 1_0 scrambled by SI-RNTI and the system information indication field is set to 1, UE1 receives and decodes the signal configuration information in the SIB26 scheduled by this DCI.
[0431] (2) A second information field is added in the DCI 1_0 scrambled by SI-RNTI to indicate the scheduling of the updated signal configuration information. For example, when the second information field is 1, the scheduling information obtained by UE1 is the updated channel configuration information.
[0432] (3) A DCI 1_0 scrambled by a new RNTI, for example, a DCI 1_0 scrambled by NES-RNTI, is introduced to indicate the scheduling of the updated signal configuration information. The information field in this DCI can include one or more of the following: time domain indication signaling, frequency domain indication signaling, VRB-to-PRB mapping, MCS indication field, RV field, and reserved bits.
[0433] In this embodiment, after the terminal receives the paging DCI, it can determine that the signal configuration information is updated according to the short message field in the paging DCI, then receives the second DCI in the first time domain position, and receives the SIB26 including the updated signal configuration information according to the second DCI. By setting the indication field for indicating the update of the signal configuration information in the paging DCI, the terminal can obtain the signal configuration information based on its own capability.
[0434] Example three, indicating the signal configuration information based on the paging DCI.
[0435] This embodiment takes the paging DCI indicating the signal configuration information as an example to illustrate the indication method of the signal configuration information and the determination method of the application time.
[0436] Assume that the base station configures one or more sets of signal configuration information for the UE through high layer signaling, such as SIB1 or other SIBs. If the base station provides more than one set of signal configuration information, each set of configuration has a corresponding configuration index. Each set of signal configuration information can use the parameter configuration method in Example 1 or Example 2.
[0437] When the base station wants to change the signal configuration information due to changes in network load, the base station sends a paging DCI (such as the first DCI) to indicate the activation / deactivation of the signal configuration information, or to indicate the index of the updated signal configuration information, and the updated signal configuration information takes effect after the second time domain position.
[0438] The specific process is shown in FIG. 5: the base station sends a paging DCI (such as the first DCI), and UE1 receives the paging DCI (such as the first DCI) on the corresponding PO. The indication method of the paging DCI includes:
[0439] Method 1: If the base station can only provide one set of signal configuration information, the paging DCI can be used to indicate the activation / deactivation state of the signal configuration information. Specifically, the Nth bit in the short message field of the paging DCI can be used, N can be selected from 5 to 8 bits, for example: the 5th bit in the short message field of the paging DCI is used to indicate the activation or deactivation of the signal configuration information, and the bit is set to 1 to represent activation and set to 0 to represent deactivation.
[0440] Method 2: If the base station can provide M sets of signal configuration information, M is an integer greater than or equal to 1, and M is predefined or based on base station configuration. Use the bit in the reserved bits (such as 5-8 bits) in the short message field of the paging DCI for indication. For example, if the base station provides 3 sets of signal configuration information, a total of 2 bits are needed for indication, and the 5th and 6th bits in the short message field are used to indicate the updated signal configuration information, as shown in Table 4 below.
[0441] Table 4: 5th and 6th bits in the short message field indicate the updated signal configuration information:
[0442] As shown in FIG. 5, the base station sends the updated signal configuration information on the PO in the first cycle 0, and until the second time domain position t2, the base station and the UE start to apply the indicated signal configuration information. The second time domain position is the frame boundary of the first cycle where the paging DCI is located, and the length of the first cycle = N* paging cycle includes the following determination methods:
[0443] Candidate method 1: The length of the first period is the BCCH modification period length in the system information update configuration in the length multiplexing protocol, i.e. the value of N is determined according to the modificationPeriodCoeff in the BCCH configuration.
[0444] Candidate method 2: The length of the first period is determined according to the first period configuration parameter N1 of the system information, which can be the same as or different from the value of N in the BCCH configuration. The value range of N can be {2, 4, 8, 16}, or {1, 2, 4, 8, 16}, or {1, 2, 3, 4}.
[0445] Candidate method 3: The length of the first period is N paging periods by default, for example, 1 paging period or 2 paging periods by default.
[0446] Candidate method 4: The first period configuration parameter N1 is a selected configuration parameter. If the base station provides the configuration of the first period configuration parameter N1, the length of the first period is determined according to candidate method 2; if the base station does not provide the configuration of the period configuration parameter N1, the length of the first period is determined according to candidate method 1.
[0447] Candidate method 5: The first period configuration parameter N1 is a selected configuration parameter. If the base station provides the configuration of the first period configuration parameter N1, the length of the first period is determined according to candidate method 2; if the base station does not provide the configuration of the period configuration parameter N1, the length of the first period is determined according to candidate method 3.
[0448] In addition, when the length of the first period is less than the system information update period, the RRC_CONNECTED UE needs to listen to the paging information at least once in each first period. That is, when the length of the first period is less than the system information update period, the length of the first period has higher priority.
[0449] In this embodiment, after the terminal receives the paging DCI, the updated signal configuration information can be determined according to the short message field in the paging DCI, and the updated signal configuration information can be applied in the second time domain position. By setting the indication field for indicating the signal configuration information in the paging DCI, the terminal can obtain the signal configuration information based on its own capability.
[0450] Example four, indicating signal configuration information based on UE-specific DCI / group-common DCI / MAC CE
[0451] This embodiment takes UE-specific DCI / group-common DCI / MAC CE, such as DCI 1_1 / 1_2 / 1_3 / 2_X / MAC CE, as an example to indicate signal configuration information, and explains the indication method of signal configuration information and the determination method of application time.
[0452] Assume that the base station configures a set or multiple sets of signal configuration information for the UE through high-layer signaling, such as SIB1 or other SIBs, or RRC signaling. If the base station provides more than one set of signal configuration information, the parameter configuration method in each of the examples in the above embodiment is used.
[0453] When the base station wants to change the signal configuration information due to changes in the load in the network, the base station sends UE-specific DCI (such as the first DCI) to indicate the activation / deactivation or updated signal configuration information index of the signal configuration information, and the updated signal configuration information starts to take effect after the second time domain position. The specific process is as follows:
[0454] The base station sends UE-specific DCI, and UE1 receives the UE-specific DCI on the corresponding MO. The updated signal configuration information is indicated by the UE-specific DCI in the following methods:
[0455] Method 1: Introduce a first information field in DCI 1_1 / DCI 1_2. If the base station can only provide one set of signal configuration information, the first information field is 1 bit, for example, the information field is set to 1 to represent activation, and set to 0 to represent deactivation or deactivation. If the base station can provide M sets of signal configuration information, M is an integer value greater than or equal to 1, and M is predefined or based on the base station configuration, then the length of the first information field is bits. For example, the base station provides 3 sets of signal configuration information, which requires 2 bits for indication, and the updated signal configuration information is indicated by 2 bits as shown in Table 5.
[0456] Table 5: 2-bit indication of updated signal configuration information in DCI 1_1 / DCI 1_2:
[0457] Method 2: Introduce a first information field in DCI 1_3.
[0458] Method 2-1: In DCI 1_3, each scheduled carrier corresponds to an independent first information field, and each independent first information field is determined in the manner of the first information field in Method 1. The length of the first information field of all carriers is
[0459] For example, DCI 1_3 schedules 4 carriers, there is 1 set of signal configuration information on carrier 1, and there are 3 sets of signal configuration information on carriers 2-4, then there are M = 1 + 2 + 2 + 2 = 7 bits in total for indicating the signal configuration information on each carrier.
[0460] Method 2-2: In DCI 1_3, all CCs correspond to one first information field, where the first information field is the index in the higher layer parameter configuration list, and the UE determines the signal configuration information corresponding to the index on each CC according to the higher layer parameter configuration.
[0461] For example, DCI 1_3 schedules 3 carriers, and there are 3 sets of configuration information on each carrier. The table provided by the higher layer for DCI 1_3 has 8 indexes, and the configuration corresponding to each index is shown in Table 6. When the first information field in DCI 1_3 is indicated as index = 5, then CC1 applies signal configuration information #1, CC2 applies signal configuration information #0, and CC3 applies signal configuration information #3.
[0462] Table 6: Signal configuration information configured by higher layer
[0463] Method 3: Introduce a first information field in group common DCI.
[0464] Method 3-1: Provide the service cell ID indicated by each cell and / or the starting bit position corresponding to the information field of this service cell and / or the signal configuration information corresponding to this service cell through the first higher layer configuration parameter (for example, nesToAddModList), that is, the information provided by the first higher layer configuration parameter includes {service cell ID, starting bit position, signal configuration information}.
[0465] Assuming that nesToAddModList includes 3 service cells, which are cell#1, cell#2, and cell#3, and the cell-level-based configuration is {cell#1, 0th bit, 3 signal configuration information}, {cell#2, 2th bit, 1 signal configuration information}, and {cell#3, 3th bit, 2 signal configuration information}, respectively. The UE can determine that the DCI includes 3 cell-level indication fields based on the higher layer configuration parameter, the first indication field is used to indicate cell#1 and has a length of The second indication field is used to indicate cell#2 and has a length of The third indication field is used to indicate cell#3 and has a length of The three indication fields are concatenated according to the starting bit position in the high layer configuration parameter; or, if the high layer does not provide the starting bit position, the concatenation is performed in the order of the carrier ID from small to large.
[0466] The above method can be applied to DCI 2_0 / 1 / 4 / 5 / 7 / 8, or a new DCI format, such as DCI 2_10, is introduced.
[0467] Method 3-2: The starting bit position in the DCI is configured for the serving cell by a second configuration parameter, i.e., the starting position of the information block indication is provided for each cell.
[0468] For each information block:
[0469] According to the protocol, a 1-bit indication signal configuration information is activated or deactivated, and / or parameters for other purposes. And this 1-bit can be placed at the beginning or the end of the information block. For example, the base station configures the starting bit of the information block corresponding to cell#1 as the first bit, the starting bit of the information block corresponding to cell#2 as the fourth bit, and the starting bit of the information block corresponding to cell#3 as the eighth bit. For UE, the starting bit of the information block corresponding to cell#1 is 1, which includes the 1-bit indication field at the beginning or the end to determine the signal configuration information. The starting bit of the information block corresponding to cell#2 is the third bit, which includes the 1-bit indication field at the beginning or the end to determine the signal configuration information, and so on.
[0470] Or, the length of the information field in each information block and the corresponding indication information are determined by a third configuration parameter. For example, the base station configures the starting bit of the information block corresponding to cell#1 as the first bit and corresponding to 3 signal configuration information, the starting bit of the information block corresponding to cell#2 as the fourth bit and corresponding to 1 signal configuration information, and the starting bit of the information block corresponding to cell#3 as the eighth bit and corresponding to 2 signal configuration information. For UE, the starting bit of the information block corresponding to cell#1 is 1, which includes a 2-bit indication field to determine the signal configuration information. The starting bit of the information block corresponding to cell#2 is the third bit, which includes a 1-bit indication field to determine the signal configuration information, and so on.
[0471] The above method can be applied to DCI 2_2 / 3 / 9, or a new DCI format, such as DCI 2_10, is introduced.
[0472] Method 4: A first information field is introduced in the MAC CE to indicate the signal configuration information. For example: the signal configuration information on each cell is indicated by a first parameter, and the activation / deactivation / application of the signal configuration information on each cell is indicated by the MAC CE.
[0473] For example, based on UE capability, each cell provides at most 8 sets of signal configuration information, then 8 indication fields in MAC CE correspond to each cell. For cell#1, the base station provides 3 sets of signal configuration information; for cell#2, the base station provides 2 sets of signal configuration information; for cell#3, the base station provides 1 set of signal configuration information. The 1st set of signal configuration information of cell#1 in MAC CE is indicated as active state, the 1st set of signal configuration information of cell#2 is indicated as active state, and the 2nd set of signal configuration information of cell#3 is indicated as active state. Then the UE can determine the active state of the signal configuration information on each cell according to the indication in MAC CE.
[0474] The base station indicates the state of the signal configuration information on the PO in the first period until the second time domain position t2, and the base station and the UE start to apply the indicated signal configuration information.
[0475] Specifically, the determination method of the second time domain position t2 includes:
[0476] Method 1: The base station needs to configure the first period parameter for the UE, where the first period can be determined by the base station configuration or specified as the same as the paging period on the cell where the DCI is located. In addition, the base station needs to configure the second extension parameter, where N is an integer value configured by the higher layer. As shown in FIG. 6.
[0477] For example: The configuration of the same as the paging period on the cell where the DCI is located and the configuration of N include that the base station uses group-common DCI or MAC CE to indicate the application of the signal configuration information on cell#1, cell#2 and cell#3 on the PCell, and the base station configures the first period as 16 subframes and the second extension parameter as 2. Then the terminal needs to apply the indicated signal configuration information at the position of t2 mod 32rf=0 after receiving the group-common DCI or MAC CE.
[0478] For example: According to the direct configuration of the first period length according to the higher layer configuration, the base station uses group-common DCI or MAC CE to indicate the application of the signal configuration information on cell#1, cell#2 and cell#3 on the PCell, and the base station configures the first period as 20 subframes. Then the terminal needs to apply the indicated signal configuration information at the position of t2 mod 20rf=0 after receiving the group-common DCI or MAC CE.
[0479] Method 2: The second time domain position is slot n+X, where slot n is the time slot in which the UE receives the downlink DCI or the scheduling configuration information DCI, or the time slot in which the ACK / NACK feedback corresponding to the DCI is performed, and X is a time slot that is protocol default or is configured by a higher layer.
[0480] Method 2-1: Assuming that the base station uses a group-common DCI to indicate the activation / deactivation / index of the signal configuration information, the signal configuration information indicated in the DCI takes effect at slot n+X, where n is the time slot in which the UE receives the DCI, and X is a time slot interval that is set based on the UE capability or the subcarrier spacing of the cell. As shown in FIG. 7.
[0481] Method 2-2: Assuming that the base station uses a UE-specific DCI or a MAC CE to indicate the activation / deactivation / index of the signal configuration information, the signal configuration information indicated in the DCI takes effect at slot n+X, where n is the first DL time slot number corresponding to the ACK / NACK feedback after the UE receives the DCI, and X is a time slot interval that is set based on the UE capability or the subcarrier spacing of the cell. As shown in FIG. 8.
[0482] In this embodiment, after the terminal receives the DCI, the terminal can determine the updated signal configuration information according to the newly added indication field in the DCI, and the updated signal configuration information takes effect at the second time domain position. By setting the indication field for indicating the signal configuration information in the DCI, the terminal can obtain the signal configuration information based on its own capability.
[0483] Example Five, application condition of the first time domain position or the second time domain position.
[0484] When the signal configuration information before the update is a subset of the signal configuration information after the update, the determination manner of the first time domain position or the second time domain position is:
[0485] Assuming that the base station provides the terminal with a set of legacy PRACH configurations and a set of additional PRACH configurations for NES, the base station can use the scheme related in the embodiments of the present disclosure to indicate the activation / deactivation of the additional PRACH configurations.
[0486] State 1: Indicating "activation", the UE can apply the legacy PRACH configurations and the additional PRACH configurations, i.e., the signal configuration information before the update is a subset of the signal configuration information after the update, i.e., the case of increasing resources;
[0487] State 2: Indicating "deactivation", the UE can only use the legacy PRACH configurations, i.e., the case of reducing resources;
[0488] Assuming that the base station adopts the indication method in example one / example two / example three / instance four, taking example three as an example:
[0489] When the paging DCI indication signal configuration information is "activated state", the second time domain position can be determined by the method of slot n+X, where slot n is the time slot of receiving the downlink DCI, and X is the time interval determined based on the UE capability or configured by the higher layer.
[0490] When the paging DCI indication signal configuration information is "deactivated state", the second time domain position can be determined in the manner described in example three.
[0491] For the case where the updated signal configuration information is a subset of the signal configuration information before the update, the first time domain position or the second time domain position is the time domain position corresponding to the frame boundary of the first period in which the terminal receives the DCI.
[0492] This embodiment will not repeat the specific determination method of the first time domain position or the second time domain position.
[0493] Example six, UE receives two types of DCI at the same time.
[0494] As shown in FIG. 9, assuming that the UE receives a first DCI, i.e. a DCI scrambled by P-RNTI, in the first period 0, for indicating signal configuration information, and receives a second DCI, e.g. DCI 1_1 / 1_2 / 1_3 / 2_X, in the first period 0, for indicating signal configuration information.
[0495] Scheme 1: The signal configuration information indicated by the first DCI and the second DCI sent by the network side device in the same first period 0 is the same through the protocol.
[0496] For example: the first DCI indicates that the additional PRACH configuration is activated state, and the second DCI indicates that the additional PRACH configuration is also activated state. If the additional PRACH configuration indicated by the second DCI is deactivated state, it is considered as network error indication, at this time, the UE can determine the signal configuration information according to any indication.
[0497] Scheme 2: the UE selects the signal configuration information indicated by the latest received DCI as the effective indication according to the time sequence of receiving the two DCIs in the first period. According to the above scenario, the UE selects the signal configuration information indicated by the second DCI as the effective indication.
[0498] Scheme 3: The UE always takes the signal configuration information in the paging DCI in the first cycle as the effective indication. According to the above scenario, the UE takes the signal configuration information indicated by the first DCI as the effective indication. Or the protocol stipulates that the DCI 1_1 / DCI 1_2 / DCI 1_3 / group-common DCI is the effective indication, and then the UE takes the signal configuration information indicated by the second DCI as the effective indication.
[0499] Scheme 4: The RRC_CONNECTED UE receives the paging DCI and considers that the signal configuration information indicated by the DCI is not effective. Then according to the above scenario, the UE takes the signal configuration information indicated by the second DCI as the effective indication.
[0500] Embodiments of the present disclosure define a first information field in the first DCI, which is used to indicate that the signal configuration information is updated or to indicate the related information of the signal configuration information. After receiving the first DCI, the terminal can obtain the content of the signal configuration information indicated by the first information field by decoding the first information field. Other terminals do not have the ability to decode the first information field, and can ignore the information, thereby avoiding resource waste.
[0501] As shown in FIG. 10, the embodiments of the present disclosure also provide a method for indicating configuration information, applied to a network side device, comprising:
[0502] Step 1001: The network side device sends a first DCI, wherein the first DCI includes a first information field, and the first information field is used to indicate one of the following:
[0503] The signal configuration information is updated;
[0504] The related information of the signal configuration information.
[0505] In this embodiment, a special information field related to configuration information update is defined in the first DCI, which is used to indicate that the signal configuration is updated or to indicate the updated signal configuration information. The first information field can be an information field that already exists in the first DCI but is not used, or can be a newly added information field.
[0506] Wherein, the first information field can indicate that the signal configuration information is updated, and after receiving the first DCI, the terminal can determine that the signal configuration information is updated by decoding the first information field, and can determine whether to receive the updated signal configuration information according to the requirement.
[0507] The first information field can also directly indicate the related information of the signal configuration information, for example, the first information field directly indicates the index of the updated signal configuration information, or indicates the activated signal configuration information, or indicates the deactivated signal configuration information. Then the terminal can determine whether the signal configuration information is updated according to the indication of the first information field, and can determine the updated signal configuration information.
[0508] In some embodiments, the first information field can be pre-configured, and the terminal and the network side device can know the position and other information of the first information field for indicating the update of the signal configuration information and / or the related information of the signal configuration information. In some embodiments, the terminal capable of decoding the first information field is a terminal with network energy saving (NES) capability, for example, if the network side device configures the terminal with the parameters related to the first information field, and the UE has the capability of decoding the first information field, the UE can obtain the indication content of the first information field after receiving the first DCI. The legacy UE does not have the capability of decoding the first information field and / or the network side device does not configure the legacy UE with the parameters related to the first information field, so the legacy UE ignores the first information field after receiving the first DCI.
[0509] The signal configuration information is related information for ensuring the normal work of the terminal under network coverage, and in some embodiments, the signal configuration information includes at least one of the following:
[0510] 1) Physical random access channel (PRACH) configuration information; the signal configuration information can include PRACH configuration parameters configured for terminals with network energy saving capability, or additional PRACH configuration parameters, such as additional PRACH configuration, additional PRACH configuration index, additional parameters for determining PRACH time domain and / or frequency domain resources, etc.
[0511] 2) Paging configuration information; the signal configuration information includes paging parameters or additional paging parameters configured for terminals with network energy saving capability, such as paging cycle, number of paging frames, number of paging occasions, etc.
[0512] 3) Synchronization signal block (SSB) configuration information. The signal configuration information includes SSB parameters configured for terminals with network energy saving capability, such as SSB cycle, position of SSB in burst, etc.
[0513] Embodiments of the present disclosure define a first information field in the first DCI, which is used to indicate that the signal configuration information is updated or the related information of the signal configuration information. After receiving the first DCI, the terminal can obtain the content of the signal configuration information indicated by the first information field by decoding the first information field. If the terminal does not have the capability to decode the first information field, the terminal can ignore the information, thereby avoiding resource waste.
[0514] In some embodiments, the first DCI in the embodiments of the present disclosure can also be replaced by a MAC CE, and the MAC CE includes the first information field, which is used to indicate at least one of the following: the signal configuration information is updated; the related information of the signal configuration information. Adding the first information field in the MCE CE indicates the signal configuration information applied to the current carrier or other carriers.
[0515] As an optional embodiment, the method further comprises:
[0516] If the first information field indicates that the signal configuration information is updated, a second DCI is sent at a first time domain position, and the second DCI is used to schedule the signal configuration information;
[0517] The updated signal configuration information is sent.
[0518] In this embodiment, the terminal receives the first DCI, and if the first information field in the first DCI indicates that the signal configuration information is updated, the network side device sends a second DCI at a first time domain position, and the terminal can start listening and receiving the second DCI at the first time domain position, and the second DCI is used to schedule the updated signal configuration information.
[0519] The first time domain position is a pre-configured or pre-defined position, and after the terminal determines that the signal configuration information is updated according to the first DCI, the terminal can start listening to the second DCI at the first time domain position and receive the updated signal configuration information. The updated signal configuration information can be carried by system information, such as SIB1 or a new SIB26.
[0520] In some embodiments, the first DCI can be a paging DCI, and the first information field can be a certain bit field in the short message field in the paging DCI, such as the a-th bit in the short message which is not used, and the optional bit position a is {5, 6, 7, 8}.
[0521] In some embodiments, the first information field is only used to indicate the terminal with network energy saving capability, and / or the terminal configured with the parameters related to the first information field, and / or the terminal with the capability to decode the first information field. If the terminal is another terminal (such as a legacy UE), the indication field can be ignored.
[0522] As an optional embodiment, the first time domain position comprises one of the following:
[0523] (1) a time domain position corresponding to a frame boundary of a first period in which the first DCI is located;
[0524] In some embodiments, the length of the first period is N times the length of a paging cycle.
[0525] wherein the value of N is multiplexed with the value of a modification period coefficient (modificationPeriodCoeff) of system information, or the value of N is configured by a network side device, or the value of N is predefined.
[0526] In this embodiment, the first time domain position can be a frame boundary of the first period in which the first DCI is located. For example, in the case that the terminal receives the first DCI and the first information field in the first DCI indicates that the signal configuration information is updated, the terminal can start monitoring the second DCI at the frame boundary of the first period and receive the updated signal configuration information.
[0527] wherein the first period is a preconfigured or predefined period, and the length of the first period can be N*pagingcycle, wherein pagingcycle is a paging cycle provided by system information. N can be multiplexed as a parameter modificationPeriodCoeff configured by system information; or the network side device separately configures N, for example, the value range of N is configured as {2, 4, 8, 16}, or the value range of N is configured as {1, 2, 4, 8, 16}, or the value range of N is configured as {1, 2, 3, 4}. N can also be a predefined parameter, for example, the default value is 1 or 2.
[0528] In some embodiments, if the network side device configures the parameter N, the terminal can determine the length of the first period by using the parameter N configured by the network side; otherwise, the terminal multiplexes modificationPeriodCoeff or a predefined N value to determine the length of the first period.
[0529] In this embodiment, after the terminal receives the first DCI, if the first information field indicates that the signal configuration information is updated, the terminal can receive the second DCI at the frame boundary of the first period in which the first DCI is located, and receive the updated signal configuration information based on the second DCI.
[0530] (2) a position of X time slots after the first DCI;
[0531] In this embodiment, the terminal can start receiving the second DCI at a position X time slots after the first DCI, for example, the first time domain position is slot n+X, where slot n is the time slot position at which the UE receives the first DCI, and X can be a number of time slots that is protocol default or configured by a higher layer.
[0532] In some embodiments, the second DCI includes at least one of the following:
[0533] 1) DCI scrambled by an SI-RNTI, the DCI scrambled by the SI-RNTI including a second information field used to indicate that the second DCI is used to schedule updated signal configuration information;
[0534] 2) DCI scrambled by another RNTI, the DCI scrambled by the other RNTI being used to schedule updated signal configuration information.
[0535] In this embodiment, the network side device indicates that signal configuration information is updated through a first information field of a first DCI, and sends a second DCI at a first time domain position, which can be a DCI 1_0 scrambled by an SI-RNTI, for example, M bits are introduced in the DCI 1_0 to indicate that the DCI 1_0 is used to schedule updated signal configuration information.
[0536] The second DCI can also be a DCI scrambled by another RNTI (such as a new RNTI), for example, a DCI 1_0 scrambled by an NES-RNTI. In this case, the second DCI can include one or more of time domain indication signaling, frequency domain indication signaling, VRB-to-PRB mapping, MCS indication field, RV field, and reserved bits.
[0537] As an optional embodiment, if the first information field is used to indicate related information of signal configuration information, the updated signal configuration information takes effect at a second time domain position;
[0538] The related information of the signal configuration information includes at least one of the following:
[0539] An index corresponding to the updated signal configuration information;
[0540] Activation of signal configuration information;
[0541] Deactivation of signal configuration information.
[0542] In this embodiment, the network-side device sends the first DCI. If the first information field of the first DCI indicates the related information of the signal configuration information, for example, indicates the index corresponding to the updated signal configuration information, it is considered that the updated signal configuration information takes effect at the second time domain position, and it can also be understood that the terminal can start using the updated signal configuration information at the second time domain position.
[0543] In some embodiments, the method further comprises: sending M signal configuration information to the terminal, M being greater than or equal to 1; wherein when M is greater than or equal to 2, each of the signal configuration information has a corresponding index.
[0544] In this embodiment, the network-side device can pre-configure one or more signal configuration information as candidates for the terminal. When multiple signal configuration information are configured, each of the signal configuration information has a corresponding index (or number). When the network-side device sends the first DCI, it can directly indicate the index of the updated signal configuration information in the first information field, and the terminal can determine the updated signal configuration information according to the index.
[0545] Alternatively, the first information field can directly indicate the activated signal configuration information, and the terminal considers that the activated signal configuration information is the updated signal configuration information. Alternatively, the first information field can also directly indicate the activation or deactivation state. For example, the network-side device only pre-configures one signal configuration information as a candidate, and can indicate activation in the first information field of the first DCI. The terminal determines that the pre-configured signal configuration information is activated, and the signal configuration information is the updated signal configuration information. Alternatively, the first information field of the first DCI indicates deactivation, and the terminal determines that the current signal configuration information is deactivated, and the pre-configured signal configuration information is the updated signal configuration information.
[0546] In some embodiments, the second time domain position includes one of the following:
[0547] (1) the time domain position corresponding to the frame boundary of the first period of the first DCI;
[0548] In some embodiments, the length of the first period is N times the length of the paging period.
[0549] Wherein, the value of N is reused the value of modificationPeriodCoeff, or the value of N is configured by the network-side device, or the value of N is predefined.
[0550] In this embodiment, the second time domain position can be a frame boundary of a first period in which the first DCI is located. For example, the network-side device transmits the first DCI, and a first information field in the first DCI indicates an index of the updated signal configuration information. The terminal determines that the updated signal configuration information takes effect at the frame boundary of the first period, which can also be understood as that the updated signal configuration information is used starting from the frame boundary of the first period. The determination method of the length of the first period is not described herein.
[0551] (2) a position of X time slots after the first DCI;
[0552] For example, the network-side device transmits the first DCI, and a first information field in the first DCI indicates an index of the updated signal configuration information. The terminal determines that the updated signal configuration information takes effect at a position of X time slots after the first DCI, which can also be understood as that the updated signal configuration information is used starting from the position of X time slots after the first DCI.
[0553] For example, the second time domain position is slot n+X, where slot n is a time slot position at which the UE receives the first DCI, and X can be a time slot number that is protocol-default or high-layer configured.
[0554] (3) a position of Y time slots after a feedback time slot corresponding to the first DCI; where X and Y are positive integers.
[0555] In this embodiment, the feedback time slot corresponding to the first DCI is, for example, an ACK / NACK feedback time slot corresponding to the first DCI. For example, the network-side device transmits the first DCI, and a first information field in the first DCI indicates an index of the updated signal configuration information. The terminal determines that the updated signal configuration information takes effect at a position of Y time slots after the ACK / NACK feedback time slot corresponding to the first DCI, which can also be understood as that the updated signal configuration information is used starting from the position of Y time slots after the ACK / NACK feedback time slot corresponding to the first DCI.
[0556] In some embodiments, the first time domain position or the second time domain position includes one of the following:
[0557] a time domain position corresponding to a frame boundary of a first period in which the first DCI is located;
[0558] a position of X time slots after the first DCI;
[0559] a position of Y time slots after a feedback time slot corresponding to the first DCI;
[0560] where X and Y are positive integers.
[0561] In some embodiments, in a case where the updated signal configuration information is a subset of the pre-updated signal configuration information, the first time domain position or the second time domain position is a time domain position corresponding to a frame boundary of a first period in which the first DCI is located.
[0562] Alternatively,
[0563] In a case where the pre-updated signal configuration information is a subset of the updated signal configuration information, the first time domain position or the second time domain position is: a position of X time slots after the first DCI, or a position of Y time slots after a feedback time slot corresponding to the first DCI.
[0564] As an optional embodiment, the first DCI includes at least one of the following:
[0565] 1) a paging DCI;
[0566] 2) a terminal-specific single-carrier scheduling DCI; for example, DCI 1_1 / DCI 1_2;
[0567] 3) a terminal-specific multi-carrier scheduling DCI; for example, DCI 1_3;
[0568] 4) a group-common DCI; for example, DCI 2_X.
[0569] In this embodiment, the first DCI can be a paging DCI, or can be other DCIs. For example, the network side device can set a first information field in the paging DCI, or can set the first information field in other DCIs, to indicate that the signal configuration information is updated or to indicate the related information of the signal configuration information. In some embodiments, the network side device can also send multiple DCIs of different types in a period to indicate that the signal configuration information is updated or to indicate the related information of the signal configuration information.
[0570] In some embodiments, the first information field includes:
[0571] In a case where the first DCI is a paging DCI, the first information field is X bits in a short message field, X being greater than or equal to 1;
[0572] Alternatively,
[0573] In a case where the first DCI is other than a paging DCI, the first information field is a newly added information field.
[0574] In this embodiment, if the first DCI is a paging DCI, multiple bits in the "short message" field of the paging DCI can be used as the first information field, for example, the 5th-8th bits in the short message field are used as the first information field to indicate that the signal configuration information is updated and / or the related information of the signal configuration information.
[0575] If the first DCI is other DCI than the paging DCI, such as terminal-specific single-carrier scheduling DCI, terminal-specific multi-carrier scheduling DCI, group-common DCI, etc., a new information field can be added to indicate the signal configuration information update.
[0576] As an optional embodiment, if the first information field is used to indicate the index corresponding to the updated signal configuration information, the length of the first information field is determined according to the number of the signal configuration information.
[0577] Or,
[0578] If the first information field is used to indicate the activation of the signal configuration information or the deactivation of the signal configuration information, the length of the first information field is 1 bit.
[0579] Or,
[0580] The length of the first information field is determined according to the high-level parameter configuration.
[0581] For example, the first DCI is terminal-specific single-carrier scheduling DCI, such as DCI 1_1 / DCI 1_2, an M-bit first information field is added in the DCI, if the M bits are used to indicate the number of the updated signal configuration information, M can be determined according to the high-level configuration parameter, M=log_2(N+1), N is the number of the signal configuration information configured by the network side device. If the M bits indicate the activation or deactivation of the signal configuration information, M=1.
[0582] For another example, the first DCI is terminal-specific multi-carrier scheduling DCI, such as DCI 1_3, a first information field is added in the DCI, for example, if each carrier CC corresponding to the DCI 1_3 corresponds to a first information field, the length of each CC corresponding to the first information field can be determined according to the indicated content, for example, if the first information field is used to indicate the number of the updated signal configuration information, the length (M) of the first information field can be determined according to the high-level configuration parameter, M=log_2(N+1), N is the number of the signal configuration information configured by the network side device. If the first information field indicates the activation or deactivation of the signal configuration information, M=1. If all the CCs scheduled by the DCI 1_3 correspond to a first information field, the first information field is the label in the high-level parameter configuration list, and the UE determines the signal configuration information corresponding to the label according to the high-level parameter configuration list.
[0583] For example, the first DCI is a group common DCI, such as DCI 2_X, and a first information field is added in the DCI. If a high-layer configuration parameter (e.g., nesToAddModList) is provided, a service cell ID indicated by each cell is provided, and / or a starting bit position corresponding to the service cell is provided, and / or signal configuration information corresponding to the service cell is provided, i.e., the high-layer configuration parameter provides {service cell ID, starting bit position, signal configuration information}. The length of the first information field corresponding to each service cell is determined according to the length of the first information field in the DCI is determined
[0584] If the high-layer configuration parameter is the starting bit position of the service cell configuration in the DCI, i.e., each cell provides the starting position of the information block indicated by the corresponding information block, for each information block, 1 bit is used to indicate the activation or deactivation of the signal configuration information according to the protocol, and / or parameters for other purposes. The 1 bit can be placed at the starting 1 bit or the last 1 bit of the information block. Alternatively, the length of the first information field in each information block and the corresponding indication information are determined by other configuration parameters.
[0585] As an optional embodiment, if the first DCI sent by the network side device in the first period includes a paging DCI and a DCI other than the paging DCI, the signal configuration information satisfies a first condition;
[0586] The first condition includes one of the following:
[0587] The related information of the signal configuration information indicated by the paging DCI is the same as the related information of the signal configuration information indicated by the other DCI;
[0588] If the related information of the signal configuration information indicated by the paging DCI is different from the related information of the signal configuration information indicated by the other DCI, the related information of the signal configuration information indicated by the latest sent DCI is valid;
[0589] If the related information of the signal configuration information indicated by the paging DCI is different from the related information of the signal configuration information indicated by the other DCI, the related information of the signal configuration information indicated by the paging DCI is valid;
[0590] If the related information of the signal configuration information indicated by the paging DCI is different from the related information of the signal configuration information indicated by the other DCI, the related information of the signal configuration information indicated by the other DCI is valid.
[0591] In this embodiment, if the network side device simultaneously transmits different types of DCI in the first period, such as paging DCI and terminal-specific single-carrier scheduling DCI, paging DCI and terminal-specific single-multiple-carrier scheduling DCI, paging DCI and group-common DCI, and the like, the signal configuration information indicated by the two types of DCI is the same, which can also be understood as that the UE does not expect that the signal configuration information indicated by the DCI scrambled by the P-RNTI and the DCI 1_1 / DCI 1_2 / DCI 1_3 / group-common DCI received in the same first period is different.
[0592] Alternatively, if the network side device simultaneously transmits different types of DCI in the first period, the signal configuration information of the UE is determined according to the latest received DCI, or is determined according to the DCI scrambled by the P-RNTI, or is determined according to the DCI 1_1 / DCI 1_2 / DCI 1_3 / group-common DCI, and the specific determination manner can be preconfigured or predefined.
[0593] In an embodiment of the present disclosure, a first information field for indicating that signal configuration information is updated or for indicating related information of the signal configuration information is defined in the first DCI. After the terminal receives the first DCI, the content of the signal configuration information indicated by the first information field can be obtained by decoding the first information field. If the terminal does not have the capability of decoding the first information field, the information can be ignored, thereby avoiding resource waste.
[0594] The above embodiments introduce the indication method of the configuration information of the present disclosure, and the following embodiments will further illustrate the corresponding device in combination with the drawings.
