[0280] Figure 2 This is an interactive schematic diagram illustrating an information processing method according to an embodiment of this disclosure. For example... Figure 2 As shown, this disclosure relates to an information processing method for a communication system 100, the method comprising:

[0281] In step S2101, network device 102 sends first information to terminal 101.

[0282] In some embodiments, terminal 101 receives first information sent by network device 102.

[0283] In some embodiments, the first information indicates that the terminal determines whether the network device supports or expects the terminal to operate in a first mode.

[0284] In some embodiments, the first information instructs the terminal to determine whether the network device supports or expects the terminal to operate in a second mode.

[0285] The first mode and the second mode can be different working modes for the terminal.

[0286] In some embodiments, the terminal operates at a peak rate in the second mode that is higher than the peak rate in the first mode.

[0287] In some embodiments, the baseband bandwidth of the first channel supported by the terminal when operating in the second mode is greater than the baseband bandwidth of the first channel supported when operating in the first mode.

[0288] The first channel includes, but is not limited to, a data channel. This data channel may include, but is not limited to, a Physical Downlink Shared Channel (PDCCH) and / or a Physical Uplink Shared Channel (PUSCH).

[0289] In some embodiments, the peak rate may include the maximum transmit rate and / or the maximum receive rate.

[0290] In some embodiments, the peak rate may be the maximum transmit rate and / or the maximum receive rate of the baseband transmission.

[0291] In some embodiments, the first mode supports a bandwidth of 20 MHz in the radio frequency (RF) channel, a bandwidth of 20 MHz in the control channel, and a bandwidth of 5 MHz in the data channel. The second mode supports a bandwidth of only 20 MHz in the RF channel, a bandwidth of 20 MHz in the control channel, and a bandwidth of 20 MHz in the data channel. Radio frequency is also known as radio frequency.

[0292] In some embodiments, the first information may indicate a mode in which the serving cell and / or neighboring cells of the terminal support or expect the terminal to operate. This mode may include a first mode and / or a second mode.

[0293] In some embodiments, the first information includes the second parameter.

[0294] In some embodiments, the first information includes a first field.

[0295] In some embodiments, the first information includes a second field.

[0296] The first field indicates whether the network device supports or expects the terminal to work in the first mode; the second field indicates whether the network device supports or expects the terminal to work in the second mode.

[0297] In some embodiments, the first information may be carried by either the first field or the second field.

[0298] The first field carries mode information, which may include a mode identifier, etc. The first field may include one or more bits. If the first field carries information about a first mode, it indicates that the terminal supports or expects to work in the first mode; if the first field carries information about a second mode, it indicates that the terminal supports or expects to work in the second mode.

[0299] The second field may carry the maximum bandwidth supported by the network device or the expected operating bandwidth. For example, the second field may carry the baseband bandwidth supported by the first channel or the expected operating baseband bandwidth used by the terminal. In this way, the terminal can know the baseband bandwidth supported or expected by the network device based on the second field, so that the terminal knows which operating mode the network device supports or expects the terminal to operate in.

[0300] As one embodiment, the network device may send "Rel-17 Redcap support". This "Rel-17 Redcap support" indicates whether the network device supports the terminal operating in a first mode. Alternatively, the "Rel-17 Redcap support" indicates whether the network device supports the terminal operating in a second mode, or whether the "Rel-17 Redcap support" is an optional terminal capability.

[0301] As one embodiment, the network device may send "Peak-datarate-reduction-RedCap-r18", which indicates whether the network device supports the terminal operating in a first mode. Alternatively, "Peak-datarate-reduction-RedCap-r18" may indicate whether the network device supports the terminal operating in a second mode, or whether "Peak-datarate-reduction-RedCap-r18" is an optional terminal capability.

[0302] The second parameter can be any parameter used to calculate the data rate.

[0303] In some embodiments, the second parameter may be in, The maximum number of layers supported by the j-th carrier, for example, the maximum number of layers for PUSCH and / or PDSCH. f is the maximum modulation order. (j) is the scaling factor for the j-th carrier.

[0304] In some embodiments, the second parameter may also be

[0305] In some embodiments, the second parameter can be f (j) .

[0306] f (j) It can be a value agreed upon in the protocol.

[0307] Of course, the above are just a few examples of first information, and the specific implementation is not limited to the examples mentioned above.

[0308] In some embodiments, network device 102 sends a downlink message, which includes first information. The downlink message may be, for example, a system message and / or a dedicated message.

[0309] In some embodiments, the first information may include one or more bits, the different bit values ​​of which may represent whether the network device supports or expects the terminal to work in two states of a first mode, and / or represent whether the network device supports or expects the terminal to work in two states of a second mode.

[0310] Some network devices support terminals to work in the first mode in terms of both hardware and software, which can save power consumption.

[0311] In some embodiments, terminal 101 receives first information sent by network device 102.

[0312] In some embodiments, the terminal may be a RedCap terminal or an enhanced mode eRedCap terminal. The RedCap terminal here may support both the first mode and the second mode simultaneously, or support the second mode alone or the first mode alone.

[0313] For example, some RedCap terminals are very inexpensive and have simple baseband processing circuits. In this case, the RedCap terminal only supports the first mode with a lower peak rate or lower baseband bandwidth in terms of hardware, and does not support the second mode with a higher peak rate and higher baseband bandwidth.

[0314] In some embodiments, the terminal is a specific type of terminal.

[0315] This specific type of terminal can include: an R18 version Redcap terminal, an R17 version Redcap terminal, or an eRedcap terminal with 20 Mbps bandwidth. The latter may use most of the hardware implementation of the R17 version Redcap terminal, only with slightly smaller buffers when processing data. The R17 version Redcap terminal may have stronger terminal capabilities, combining the capabilities limited by R18 and / or R17 versions.

[0316] For example, the terminal supports the terminal capabilities limited to R18, meaning that the terminal can operate in the first mode during initial access.

[0317] The first mode can be: peak rate reduction and / or narrower narrowband operating mode:

[0318] For example, reducing the peak rate can reduce the terminal's peak rate to 10Mbps; where the peak rate includes the uplink peak rate and / or the downlink peak rate.

[0319] For example, scheduling that operates in the data channel uses a lower bandwidth, such as 5MHz, and its specific characteristics are as follows;

[0320] Specifically: a 5MHz baseband (BB) bandwidth is used only for PDSCH and / or PUSCH, and a 20MHz RF bandwidth is used for other channels of UL and / or DL. This 5MHz bandwidth can be used for broadcast or unicast PDSCH. Other physical channels and / or signals are still permitted to use the 20MHz bandwidth portion (BWP).

[0321] If the terminal supports the first mode, then the conditions that the peak rate limit must meet may include:

[0322] For peak rates, the constraints can be determined according to... Relax. The value can be reduced to less than or equal to 4. For example, it can be reduced to 3.2, 0.75, etc.

[0323] Certain types of terminals can operate in either the first or second mode.

[0324] Some network devices support terminals to work in the first mode in terms of both hardware and software, which can save power consumption.

[0325] Some terminals support working in the second mode in terms of both hardware and software, but do not want to work in the second mode for reasons such as saving power. In this case, the second information can indicate to the terminal that it does not want to work in the second mode.

[0326] In some embodiments, the terminal capabilities of the second mode are higher than those of the first mode.

[0327] In some embodiments, the power consumption of the terminal operating in the second mode may be higher than the power consumption of the terminal operating in the first mode.

[0328] In some embodiments, the first mode is an enhanced mode of the second mode, which may be an operating mode for terminals with specific bandwidth and / or terminals with lower power consumption.

[0329] Optionally, the information processing method may include:

[0330] In step S2102, the terminal determines whether it is operating in the first mode or the second mode.

[0331] For example, S2102 may be an optional step.

[0332] In some embodiments, S2102 may include at least one of the following:

[0333] Based on the first information, the terminal determines whether the network device supports or expects the terminal to work in the first mode;

[0334] Based on the first information, the terminal determines whether the network device supports or expects the terminal to operate in the second mode.

[0335] In some embodiments, determining that the terminal is operating in a first mode or a second mode includes at least one of the following:

[0336] The information processing method includes a first information instruction to the network device that it supports or expects the terminal to operate in a first mode, and the terminal determining that it is operating in the first mode.

[0337] In some embodiments, the information processing method includes: first information indicating that the network device does not support the terminal operating in a first mode, and first information indicating that the network device supports the terminal operating in a second mode, and the terminal determining that it is operating in the second mode.

[0338] In some embodiments, the terminal determines that it is operating in a first mode, including:

[0339] The first information indicates that the network device does not support the terminal operating in the first mode, the first information indicates that the network device supports or expects the terminal to operate in the second mode, and the terminal has the capability to operate in the second mode, and the terminal determines that it is operating in the second mode.

[0340] Some terminals support working in the second mode in terms of both hardware and software, but do not want to work in the second mode for purposes such as saving power. In this case, the terminal can determine to work in the first mode based on the instructions of the first information.

[0341] In some embodiments, the information processing method may include:

[0342] The terminal determines whether to access the target cell in a disconnected state, wherein the target cell is a cell that supports the terminal operating in the second mode.

[0343] In some cases, if a terminal detects that the signal quality of the current serving cell has dropped to a threshold, and detects that the signal quality of a neighboring cell is better than that of the current serving cell and that the signal quality of the neighboring cell is higher than the threshold, then the neighboring cell will be considered the target cell, and the terminal will reselect to access the target cell.

[0344] In some embodiments, the terminal may determine whether the target cell supports the terminal working in the second mode according to the protocol.

[0345] In some embodiments, the first information may indicate whether the current serving cell and neighboring cells support the terminal operating in the second mode. Therefore, based on the first information, the terminal can know whether neighboring cells support the terminal operating in the second mode, and thus can use neighboring cells as target cells.

[0346] In some embodiments, the information processing method includes: the terminal operates in a first mode during the initial access process, and remains in the first operating mode after the initial access process is completed.

[0347] In some embodiments, the information processing method may include: the terminal operates in a second mode during the initial access process, and switches to a first mode after the initial access process is completed.

[0348] In some embodiments, the information processing method may include: the terminal operates in a first mode during the initial access process, and switches to a second mode after the initial access process is completed.

[0349] In step S2103, terminal 101 sends second information to network device 102.

[0350] In some embodiments, network device 102 receives second information reported by terminal 101.

[0351] In some embodiments, steps S2103 and S2102 may be performed in an alternate order or simultaneously.

[0352] In some embodiments, step S2102 is executed first, followed by step S2103. The terminal can determine its current operating mode based on the network device's support for and / or expectation of the terminal operating in a first or second mode, as indicated by the first information. Then, by executing S2103, second information indicating the terminal's current operating mode is sent to the network device.

[0353] In some embodiments, step S2103 is executed first, followed by step S2102. The second information sent by the terminal may include the terminal's capability information, which may indicate that the terminal itself supports and / or expects to operate in the first mode or the second mode.

[0354] In some embodiments, the second information indicates whether the terminal has the capability to operate in a second mode.

[0355] In some embodiments, the second information indicates whether the terminal supports or expects to work in the second mode.

[0356] In some embodiments, the second information instructs the network device to determine whether random access following the initial access of the terminal supports or is expected to operate in the second mode.

[0357] In some embodiments, the second information includes capability information.

[0358] In some embodiments, the second information includes auxiliary information UAI.

[0359] In some embodiments, the second information received by the terminal includes: capability information sent by the network device to the terminal.

[0360] In some embodiments, the second information received by the receiving terminal includes: auxiliary information UAI sent by the network device received by the terminal.

[0361] In some embodiments, capability information indicates that the terminal has the capability to operate in a second mode.

[0362] In some embodiments, UAI indicates whether the terminal supports or expects to work in the second mode.

[0363] As one embodiment: if the network device instructs the terminal to report the auxiliary information, the terminal may report the auxiliary information; otherwise, the terminal does not need to report the auxiliary information. The auxiliary information may include, but is not limited to, the aforementioned UAI.

[0364] In some embodiments, the second information includes at least one of the following:

[0365] Does the terminal have the ability to operate in the second mode after initial access?

[0366] Whether the terminal supports or expects to work in the second mode after initial access.

[0367] In some embodiments, the second information may include one or more bits, the different bit values ​​of which may represent two states of whether the terminal has the ability to operate in the second mode, and / or two states of whether the terminal supports or expects to operate in the second mode.

[0368] In some embodiments, the terminal may use any uplink message to send the second information to the network device. For example, the terminal may use an RRC message, a MAC layer message, or Uplink Control Information (UCI) to send the second information to the network device.

[0369] The MAC message may include, but is not limited to, the MAC layer control element (CE).

[0370] By reporting the second information, the terminal can facilitate network devices to control the terminal's operating mode according to communication needs and / or system capacity, or to know the possible operating modes of the terminal.

[0371] In some embodiments, the second information includes the first parameter.

[0372] In some embodiments, the second information includes a third field.

[0373] In some embodiments, the second information includes a fourth field.

[0374] In some embodiments, the second information includes a fifth field.

[0375] The first parameter and the specified threshold indicate whether the terminal supports a decrease or increase in peak rate; the third field indicates whether the terminal supports or expects to work in the second mode; the fourth field indicates whether the terminal supports the bandwidth required to work in the second mode; and the fifth field indicates whether the terminal supports a decrease or increase in peak rate.

[0376] The data rate transmitted by the terminal can be calculated using the following formula:

[0377]

[0378] Where J is the number of carriers aggregated in a single frequency band or across frequency bands, and j is the sequence number of the aggregated carriers.

[0379] The maximum number of layers supported by the j-th carrier, for example, the maximum number of layers for PUSCH and / or PDSCH;

[0380] This represents the maximum modulation order.

[0381] f (j) is the scaling factor for the j-th carrier;

[0382] For a bandwidth BW of u (j) The largest resource block (RB). (BW) (j)It is the maximum bandwidth supported by the terminal on the specified frequency band.

[0383] This is the maximum duration of an Orthogonal Frequency Division Multiplexing (OFDM) symbol in a subframe corresponding to u.

[0384] OH (j) The overhead value corresponding to the j-th carrier is as follows:

[0385] 0.14, used for downlink transmission in frequency range (FR) 1;

[0386] 0.18, used for downlink transmission of FR2;

[0387] 0.08, used for uplink transmission of FR1;

[0388] 0.10, used for uplink transmission of FR2.

[0389] In this embodiment of the disclosure, the first parameter can be any parameter used to calculate the data rate. Specifically, the first parameter can be... and f (j) Any one of them.

[0390] The specified threshold can be any value, which is the first parameter, and determines whether the terminal supports or expects to operate in the second mode. This specified threshold can be a value agreed upon in the protocol, or a threshold specified by the network device.

[0391] In some embodiments, The product of the two values ​​is compared with a specified threshold; the comparison result is used to determine whether the terminal supports or expects to work in the second mode. For example, the specified threshold can be a value such as 4, 3, 3.2, 1, or 0.75.

[0392] For example, the first parameter can be f (j) The specified threshold at this point can be any other threshold that can be used with f. (j) The preset values ​​for comparison.

[0393] It is worth noting that for cells that support Supplement UL Link (SUL) carriers, the calculation of the number of carriers can include UL carriers and / or SUL carriers that support higher data rates.

[0394] For UL reception handover between different carriers, only carriers that support multiple input multiple output (MIMO) layer merging between carriers, resulting in higher data rates, are counted in the carrier count.

[0395] The maximum data rate supported by the terminal can be calculated using the formula above.

[0396] When the terminal is camped on a single-carrier cell, then The product of these is usually not less than 4.

[0397] In some embodiments, the second information may be carried by any one of the third, fourth to fifth fields.

[0398] The third field carries mode information, which may include a mode identifier, etc. The third field may include one or more bits. If the third field carries information about the second mode, it indicates that the terminal supports or expects to work in the second mode. If the third field carries information about the first mode, it indicates that the terminal supports or expects to work in the first mode.

[0399] The fourth field may carry the maximum bandwidth supported by the terminal or the bandwidth it expects to operate at. For example, the fourth field may carry the baseband bandwidth supported by the first channel or the baseband bandwidth it expects to operate at. In this way, the network device can know the baseband bandwidth supported or expected to operate at the terminal based on the fourth field, and thus know whether the terminal supports or expects to operate in the second mode.

[0400] The fifth field directly indicates whether the terminal supports a decrease or increase in peak rate. If the terminal initially accesses in mode 1, and the fifth field indicates that the terminal supports an increase in peak rate, then the terminal supports or expects to operate in mode 2; otherwise, the terminal does not support or expects to operate in mode 2.

[0401] In some embodiments, the terminal's ability to support or expect to operate in the second mode is based on the UE, on the frequency band, or on the frequency range.

[0402] If the terminal's ability to support or expect to operate in the second mode is based on the UE, it means that the entire terminal supports or expects to operate in the second mode regardless of any frequency domain position that the terminal can support.

[0403] The system bandwidth used by a wireless communication system can be divided into one or more frequency bands. A frequency band includes one or more frequency points.

[0404] The terminal may support or expect to operate in the second mode on some frequency bands, or it may not support or expect to operate in the second mode on some frequency bands.

[0405] The terminal may support or expect to operate in the second mode within one or more frequency ranges. For example, the terminal supports or expects to operate in the second mode on frequency range (FR)1 and / or FR2.

[0406] The frequency range of FR1 can be 450MHz to 6000MHz, and it can also be called Sub 6G.

[0407] The frequency range of FR2 is 24250MHz to 52600MHz, and the corresponding maximum system bandwidth is 400MHz.

[0408] A frequency range may include one or more frequency bands.

[0409] In some real-time scenarios, the second information also includes range information, which indicates whether the terminal supports or expects to operate in the second mode based on the entire UE, or based on a frequency band, or based on a frequency range.

[0410] For example, if the terminal expects or operates in the second mode based on a frequency band, the range information may include a frequency band identifier. If the terminal expects or operates in the second mode based on a frequency range, the range information may include a frequency range identifier, etc.

[0411] Of course, this is just an example, and the actual implementation is not limited to this example.

[0412] If the terminal supports the first mode, then the conditions that the peak rate limit must meet may include:

[0413] For peak rates, the constraints can be determined according to... Relax. The value can be reduced to the first value. The first value is less than or equal to 4. For example, it can be reduced to 3.2, 0.75, etc.

[0414] As one example: the second mode is:

[0415] Higher peak rates and / or greater narrowband operating modes: for example, operating in data channel scheduling with a larger bandwidth, such as 20MHz;

[0416] Specifically:

[0417] The terminal operates in the second mode and can use a 20MHz baseband bandwidth to indicate the transmission of PDSCH and / or PUSCH. For example, a 20MHz baseband bandwidth can be used to support unicast or broadcast of PDSCH. 20MHz RF transmission can be supported for UL and / or DLC transmissions.

[0418] For peak rates, the limiting constraints may include: The value of is reduced to a second value, which may not be less than the first value. The first value may be the same as the first value, meaning that the peak rate constraint remains unchanged during the initial access process and / or after the initial access is completed.

[0419] Here, the first value and / or the second value can be one of the aforementioned specified thresholds.

[0420] As one embodiment, the terminal may report its supportOfRedCapPR1-r18. The supportOfRedCapPR1-r18 indicates whether the terminal supports the second mode, or whether the supportOfRedCapPR1-r18 is an optional terminal capability.

[0421] As one embodiment, the terminal can report its supportedRedCap-R17, which can be understood as a field or information element (IE) that indicates whether the terminal supports the second mode.

[0422] As one embodiment, the terminal can report whether it supports the feature of reducing or increasing peak data rate, for example, using a value Peak-datarate-reduction-RedCap-r18. Peak-datarate-reduction-RedCap-r18 can be understood as a field or information element (IE) that indicates whether the terminal supports reducing or increasing peak data rate.

[0423] The above fields or IE can be reported individually or in random combinations.

[0424] For example, after the terminal enters the RRC connected state, the terminal reports one or more of the following parameter combinations:

[0425] Option 1: Report and f (j) The product of the three is less than 4.

[0426] Option 2: Report supportedRedCap-R17;

[0427] Option 3: Report whether 20MHz BB bandwidth is supported;

[0428] When reporting parameters, you can report only... and f (j) A single parameter or part. For example, only one of the following should be reported: The second piece of information can also directly indicate whether a 20MHz baseband bandwidth is supported.

[0429] In some embodiments, after the terminal reports the second information, the network device may send the first information based on the second information reported by the terminal. The first information may instruct the terminal to operate in a first mode or a second mode.

[0430] In some embodiments, after the terminal reports the second information, the terminal may operate in either the first mode or the second mode according to communication needs or protocol agreements. The network device is aware of the operating modes supported or expected by the terminal, and may also be aware of the terminal's operating modes according to protocol agreements.

[0431] In some embodiments, network device 102 receives second information sent by terminal 101.

[0432] In some embodiments, network device 102 receives second information reported by terminal 101 in a connected state.

[0433] In some embodiments, network device 102 receives second information reported by terminal 101 in RRC connection state.

[0434] In some embodiments, when the terminal is in an RRC connected state, the terminal can send second information to the network device through various RRC messages. For example, this RRC message can be reused to send other RRC messages.

[0435] In some embodiments, the network device receives second information via any RRC message from the terminal transitioning from the RRC connection state to the RRC connection state.

[0436] For example, the RRC message may include, but is not limited to, at least one of the following:

[0437] RRC recovery complete message; This RRC recovery complete message can be used by the terminal to notify the network device that the terminal has entered the RRC connected state from the RRC disconnected state.

[0438] RRC connection establishment (RRCSetupComplete) completion message; This RRC connection establishment completion message can be used by the terminal to notify the network device that the terminal has entered the RRC connected state from the RRC idle state.

[0439] The RRC Reestablishment Complete message is used by the terminal to notify the network that the RRC connection has been re-established. For example, this RRC connection may involve a radio bearer (RB). This RB may include a signaling radio bearer (SRB) and / or a data radio bearer (DRB).

[0440] In this scenario, a terminal in the RRC disconnected state can send second information—whether it supports or expects to operate in the second mode—to the network device during the process of entering the RRC connected state. This allows the network device to promptly ascertain the terminal's capabilities or expectations during the RRC connected state transition. The RRC disconnected state here can include: RRC idle state and / or RRC inactive state.

[0441] In some embodiments, when a terminal sends an RRC message requesting to enter the RRC connected state in order to transmit second information, after completing the transmission of the second information, the terminal can continue to return to the RRC disconnected state, and the terminal will not further respond to the response message of the network device and enter the RRC connected state, thereby reducing the number of times the terminal enters the RRC connected state and the duration of the terminal maintaining the RRC connected state, thereby reducing power consumption.

[0442] When a network device receives an RRC message containing the second information, it can respond to the RRC message by sending a response message to the terminal according to the agreement, or it can extract the second information from the RRC message and then ignore the RRC message without sending a response message to the UE, thereby reducing the unnecessary sending of response messages by the network device.

[0443] For example, when an RRC message carries a preset indicator, it can be assumed that the RRC message is for transmitting second information, rather than the terminal needing to enter the RRC connected state. As another example, when an RRC message does not carry a preset indicator, it can be assumed that the RRC message is the terminal requesting to enter the RRC connected state and sending second information to the network device during the process of entering the RRC connected state.

[0444] In some embodiments, after receiving the second information, the network device knows the working mode that the terminal supports or expects to work, or the network device may also know the working mode of the terminal according to the protocol.

[0445] In some embodiments, at least one of steps S2101 to S2103 may be performed. For example, step S2101 may be implemented as a standalone embodiment, step S2102 may be implemented as a standalone embodiment, step S2103 may be implemented as a standalone embodiment, step S2101+S2102 may be implemented as a standalone embodiment, step S2101+S2102+S2103 may be implemented as a standalone embodiment, step S2102+S2103 may be implemented as a standalone embodiment, and step S2101+S2103 may be implemented as a standalone embodiment, but not limited thereto.

[0446] In some embodiments, steps S2102 and S2103 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0447] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0585] Figure 6 This is a schematic diagram of the architecture of an information processing method according to an embodiment of this disclosure. For example... Figure 6 As shown, the embodiments of this disclosure relate to information methods, which include:

[0586] Step S6101: The specific type of terminal operates in different working modes according to the cell's support for different features or according to the instructions of the network device.

[0587] In some embodiments, cell support for different characteristics includes: whether the network device supports the terminal operating in a first mode, and / or whether the network device supports the terminal operating in a second mode. For a specific type of terminal, according to the network device's instructions, this includes: whether the network device expects the terminal to operate in the first mode, and whether the network device expects the terminal to operate in the second mode.

[0588] In some embodiments, the specific type of terminal is the first type of terminal, namely the Redcap type terminal (Rel-18eRedCap) introduced in version R18.

[0589] The types of terminals are not limited to this. Terminals can also be, for example, Internet of Things (IoT) terminals.

[0590] In some embodiments, the terminal (referring to a specific type of terminal) operates in different working modes depending on the network device's support for different terminal characteristics or the network device's instructions.

[0591] In some embodiments, the terminal may operate in a working mode as instructed by the network device.

[0592] In some embodiments, the operating mode includes a first mode or a second mode.

[0593] In some embodiments, the terminal can determine which operating mode to use based on the support of the base station. The rules for determining which operating mode to use after the terminal obtains the base station support information can be agreed upon in a protocol.

[0594] In some embodiments, the principle agreed upon in the protocol is that the first operating mode takes precedence. That is, if the network device notifies the cell that it can support the terminal operating in the first mode, then the terminal operates in the first mode; if the network device notifies the cell that it does not support the terminal operating in the first mode, but supports the terminal operating in the second mode, then the terminal operates in the second mode.

[0595] Alternatively: If the network device notifies that the cell does not support the terminal working in the first mode, but supports the terminal working in the second mode, then the terminal with this feature will work in the second mode; (for example, it can work on the R17 base station during handover).

[0596] In some embodiments, the operating mode of the terminal includes the following definitions:

[0597] Taking the terminal working in the first mode as an example:

[0598] 1) This includes operating in the first mode during the initial access process, and then switching to a different operating mode after the initial access process (or reporting support for the second mode); or,

[0599] 2) This includes operating in the first mode both during and after the initial access process; or,

[0600] 3) Includes operation in the first mode after switching from connected state. The above features can be combined.

[0601] In some embodiments, the first mode is: a reduced peak rate and / or a narrower narrowband operating mode: for example, operating in a data scheduling mode with lower bandwidth, such as 5MHz, with the following specific characteristics:

[0602] 1) The 5MHz baseband (BB) bandwidth is used only for PDSCH (for unicast or broadcast) and PUSCH, and the 20MHz RF bandwidth is used for UL and DL. The 5MHz bandwidth here can be used for broadcast or unicast PDSCH. Other physical channels and signals still allow the use of the 20MHz bandwidth portion (BWP).

[0603] 2) This is equivalent to a feedback of the peak rate constraint conditions. For example, the conditions to be met may include: the original... Values ​​greater than or equal to 4 were relaxed, for example, relaxed to the first value.

[0604] The above features can be combined. It is also possible to operate solely on the peak rate reduction (bandwidth maintained at 20M during scheduling).

[0605] In some embodiments, the first mode can be the working mode of R18 eRedcap.

[0606] In some embodiments, the first mode may be an operating mode with reduced peak rate;

[0607] In some embodiments, the second mode is different from the first mode; the second mode is a peak rate enhancement and / or a greater bandwidth operating mode. For example, when the terminal operates in the second mode, it uses a larger bandwidth, such as 20MHz, for data scheduling. Its specific characteristics are as follows:

[0608] 1) A 20MHz baseband (BB) bandwidth is used for PDSCH (for unicast or broadcast) and PUSCH, and a 20MHz RF bandwidth is used for UL and DL.

[0609] 2) The peak rate constraint has been relaxed; for example, the conditions to be met may include: the original... Values ​​greater than or equal to 4 are relaxed, for example, relaxed to below 4, i.e., relaxed to the second value. The second value is not less than the first value.

[0610] In some embodiments, the second mode can be the working mode of R17 Redcap.

[0611] In some embodiments, the second mode may be an operating mode with increased peak rate.

[0612] Step S6102: The network device's support for terminals with different characteristics, or the network device's instruction for terminals to work in different working modes, can be broadcast in system messages or notified via dedicated signaling.

[0613] In some embodiments, if a network broadcast is configured to support R18 eRedcap access, then the network device supports the terminal operating in the first mode.

[0614] In some embodiments, network broadcasting configured to support R17 eRedcap access enables the terminal to operate in the second mode.

[0615] In some embodiments, network devices indicate the desired operating mode for the terminal via dedicated messages (referring to dedicated signaling, such as information carried in a handover command).

[0616] Step S6103: Based on the cell's support for different characteristic terminals, specific types of terminals can operate in different modes and additional terminal capabilities can be added for judgment.

[0617] In some embodiments, if a network device notifies the cell via first information that it does not support the terminal working in the first mode, but supports the terminal working in the second mode, and the terminal needs to have the ability to work in the second mode, then the terminal can work in the second mode.

[0618] In some embodiments, terminal capability information is added to determine whether access to an R17 Redcap cell (i.e., the target cell) is allowed in the non-connected state. This capability does not need to be reported to the base station, and therefore no terminal capability reporting indication is required.

[0619] In some embodiments, an optional feature without a terminal (UE) radio access capability parameter is shown in Table 1 (First Capability Support Information):

[0620]

[0621] Table 1

[0622] In some embodiments, terminal capability information is added to determine whether it is allowed to operate in a second working mode in an R17 Redcap cell (i.e., handover access target cell) during connected state. This capability needs to be reported to the base station (second capability support information).

[0623] Table 2 below is an example of second capability support information, such as the parameter definitions for the supportOfRedCap-r18 terminal:

[0624]

[0625] Table 2

[0626] As one embodiment, the first capability support information and the second capability indication information have a certain correlation. For example, supporting the first...

[0627] Terminals that support capability information must also support secondary capability indication information.

[0628] In some embodiments, a Rel-18eRedCap 20M+PR1 type terminal can also be defined. The definition of the Rel-18eRedCap20M+PR1 terminal includes the following characteristics:

[0629] This terminal is a reduced-capacity user device.

[0630] 1) If the cell supports Rel-18eRedCap, during initial access, 5MHz of baseband (BB) bandwidth is used only for PDSCH (for unicast or broadcast) and PUSCH, and 20MHz of RF bandwidth is used for UL and DL. The 5MHz bandwidth here can be used for either broadcast or unicast PDSCH. After initial access, it is optional to report that 20MHz of baseband (BB) bandwidth is used only for PDSCH (for unicast or broadcast) and PUSCH, and 20MHz of RF bandwidth is used for UL and DL.

[0631] Other physical channels and signals are still allowed to use a maximum bandwidth portion (BWP) of 20MHz, with a maximum terminal RF+ baseband bandwidth.

[0632] Relaxing the restrictions on peak rate reduction, for example, includes: v Layers ·Q m f equals 3 or 3.2.

[0633] Supports RedCap advance indication based on random access based on Msg1, MsgA (if the UE indicates support for twoStepRACH-r16)(FFS) and / or Msg3.

[0634] 2) If the cell does not support R18 eRedcap, the maximum FR1 RedCap terminal bandwidth is 20MHz; the maximum FR2 RedCap terminal bandwidth is 100MHz.

[0635] 3) Supports RedCap advance indication based on random access based on Msg1, MsgA (if the UE indicates support for twoStepRACH-r16) and / or Msg3.

[0636] 4) The terminal is required to support a maximum of 8 Data Radio Bearers (DRBs).

[0637] 5) The terminal is required to support 12-bit Packet Data Convergence Protocol (PDCP) sequence numbers (SN), and optionally supports 18-bit PDCP SN.

[0638] 6) Mandatory support for 12-bit Radio Link Control (RLC) Acknowledgment Mode (AM) SN, with optional support for 18-bit RLC AM SN.

[0639] The terminal can be defined simply as FR1, or it can support 1RX (Receive communication unit) or 2RX.

[0640] For FR1, if one receive (Rx) branch is supported, it is a 1DL MIMO layer; if two Rx branches are supported, it is a 2DL MIMO layer.

[0641] For FR2, it can support 1 or 2 DL MIMO layers, and always supports 2 Rx branches.

[0642] For FR1 and FR2, RedCap terminals do not support UE features and capabilities related to more than 2 UE Rx branches or 2DL or more MIMO layers, as well as UE features and capabilities related to more than 1 UE Tx branch or 1UL or more MIMO layers.

[0643] II. Table 3 below provides the relevant parameter definitions for the supportOfRedCapPR1-r18 terminal, using FR1 as an example:
