[0150] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0151] In related technologies, due to the limited system bandwidth of lightweight UEs, frequency hopping may cause them to exceed the system bandwidth and become inoperable. Therefore, preventing lightweight terminals from exceeding the system bandwidth during frequency hopping has become an urgent problem to be solved.

[0152] To address this issue, embodiments of this disclosure provide a frequency hopping control method and apparatus.

[0153] Figure 1 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure, executed by a UE. In this embodiment, both lightweight UEs and non-lightweight UEs use the same initial uplink BWP (Bandwidth Partial). As mentioned above, if the frequency hopping mechanisms used by lightweight and non-lightweight UEs are the same, a situation may arise where the lightweight UE jumps out of its system bandwidth during a certain frequency hopping. Therefore, in embodiments of this disclosure, under the premise that the frequency hopping mechanisms used by lightweight and non-lightweight UEs are the same, the frequency hopping parameters can be adjusted according to the UE type to avoid the lightweight UE jumping out of its system bandwidth range.

[0154] In the embodiments of this disclosure, after determining parameters such as the frequency hopping offset value, the number of frequency hoppings, and the frequency hopping time-domain granularity, the UE can perform frequency hopping according to the determined frequency hopping parameters. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include the frequency hopping offset value, the number of frequency hoppings, and the frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the number of frequency hoppings is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; the frequency hopping time-domain granularity is used to support the implementation of cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0155] like Figure 1 As shown, the frequency hopping control method includes the following steps:

[0156] Step 101: Determine the type of UE.

[0157] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, while a non-lightweight UE can be understood as a regular NR terminal supporting all NR features. In LTE 4G systems, two major technologies, MTC (Machine-Type Communications) and NB-IoT (Narrowband Internet of Things), were proposed to support IoT services. These two technologies are mainly aimed at low-speed, high-latency scenarios, such as meter reading and environmental monitoring. Currently, NB-IoT can only support a maximum speed of a few hundred kilobytes per second, and MTC can only support a maximum speed of a few megabytes per second. However, on the other hand, with the continuous development of IoT services, such as video surveillance, smart homes, wearable devices, and industrial sensing and monitoring, these services typically require speeds of tens to 100 megabytes per second, while also having relatively high latency requirements. Therefore, the MTC and NB-IoT technologies in LTE are difficult to meet these requirements. In this embodiment, this new UE type is collectively referred to as Reducedcapability UE, or lightweight UE, while current ordinary terminals are referred to as non-lightweight UE in the embodiments of this disclosure.

[0158] In one embodiment of this disclosure, a lightweight UE typically has the following characteristics:

[0159] -Low cost, low complexity

[0160] - Some degree of coverage enhancement

[0161] - Power saving.

[0162] Since the current NR (New Radio) interface is designed for high-end terminals with high speed and low latency, it cannot meet the requirements of lightweight UEs. Therefore, the current NR system needs to be modified to meet the requirements of lightweight UEs. For example, to meet requirements such as low cost and low complexity, the bandwidth of lightweight UEs can be limited, such as to 10 MHz or 20 MHz, or the number of receiving antennas of lightweight UEs can be limited. For power saving, possible optimization directions include reducing the processing complexity of user equipment, such as receiving only the PDCCH (Physical Downlink Control Channel) channel in the same time slot, and entering a micro-sleep state at other symbol times in the same time slot. For a certain degree of coverage enhancement, multiple retransmissions of each channel can be performed to reduce the code rate.

[0163] In one embodiment of this disclosure, the UE type can be determined based on the bandwidth. In another embodiment, the base station can determine the UE's bandwidth and, based on that bandwidth, determine the UE's type: either a lightweight UE or a non-lightweight UE. In other embodiments of this disclosure, the two UE types can also be distinguished based on the physical random access channel (PRACH).

[0164] like Figure 2 As shown, in one embodiment of this disclosure, the frequency hopping offset value is used to determine the starting position of each hop; the number of frequency hopping can be understood as the number of hops: for example, Message3 is transmitted repeatedly 8 times, the time-domain granularity of frequency hopping is 1 slot, and the number of hops can be 4, then the frequency hopping mode can be as follows: Figure 2 As shown, that is, during the repetition process, the transmission of msg3 has four different frequency domain positions (such as...). Figure 2 (The gray part within).

[0165] Step 102: Determine the frequency hopping parameters based on the UE type.

[0166] In embodiments of this disclosure, the frequency hopping parameters include one or more of the following: frequency hopping start position, frequency hopping offset, and frequency hopping count. In one embodiment of this disclosure, the frequency hopping parameters are determined based on the type of UE. Specifically, independent frequency hopping parameters can be set for lightweight UEs and for non-lightweight UEs. In embodiments of this disclosure, lightweight UEs can set their frequency hopping parameters according to their own system bandwidth, thereby avoiding situations where they hop outside the system bandwidth of the lightweight UE. In another embodiment of this disclosure, the same frequency hopping parameters can be set for both lightweight and non-lightweight UEs, but these parameters need to take into account the lightweight UE to prevent it from hopping outside the system bandwidth range of the lightweight UE. Alternatively, the frequency hopping parameters for non-lightweight UEs can remain unchanged, while the frequency hopping parameters for lightweight UEs can be adjusted.

[0167] In embodiments of this disclosure, one or more of the frequency hopping start position, frequency hopping offset, and number of frequency hopping can be adjusted to avoid situations where the frequency hopping exceeds the system bandwidth range of a lightweight UE.

[0168] Step 103: Perform frequency hopping according to the determined frequency hopping parameters.

[0169] In embodiments of this disclosure, frequency hopping can be performed based on frequency hopping parameters determined by the UE. For example, frequency hopping can be performed based on the frequency hopping start position, frequency hopping offset, and frequency hopping count.

[0170] In embodiments of this disclosure, frequency hopping parameters can be adjusted according to the type of UE, thereby avoiding situations where the frequency hopping exceeds the system bandwidth range of a lightweight UE.

[0171] Figure 3 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure. Executed by the UE, the UE determines frequency hopping parameters such as the frequency hopping offset value, the number of hopping cycles, and the frequency hopping time-domain granularity, and then performs frequency hopping according to these parameters. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include the frequency hopping offset value, the number of hopping cycles, and the frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the number of hopping cycles is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; and the frequency hopping time-domain granularity is used to support cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0172] like Figure 3 As shown, in this embodiment, the frequency hopping parameter can be the frequency hopping start position. The frequency hopping control method includes the following steps:

[0173] Step 301: Determine the type of UE.

[0174] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, and a non-lightweight UE can be understood as a regular NR terminal that supports all NR features.

[0175] Step 302: Determine the corresponding frequency hopping start position according to the UE type.

[0176] In one embodiment of this disclosure, the frequency hopping start position can be determined in the same way for both non-lightweight UEs and lightweight UEs. However, for lightweight UEs, after determining the frequency hopping start position, it is necessary to adjust the frequency hopping start position to avoid hopping out of the system bandwidth range of the lightweight UE.

[0177] In one embodiment of this disclosure, the frequency hopping parameter can be determined as the frequency hopping start position in the following manner.

[0178] In one embodiment of this disclosure, in response to the UE being a lightweight UE, the initial position of the starting frequency hopping of the lightweight UE is first determined, and then the starting position of frequency hopping is determined based on the initial position of the starting frequency hopping.

[0179] In one embodiment of this disclosure, a corresponding adjustment value can be determined based on the system bandwidth of the lightweight UE, and then the initial position of the starting frequency hopping can be adjusted based on the adjustment value to determine the starting position of the frequency hopping.

[0180] In one embodiment of this disclosure, the adjustment value is determined in the following manner:

[0181] The agreement specifies; or, the signaling configuration is sent via the base station.

[0182] In one embodiment of this disclosure, the adjustment value can be fixed by a protocol or dynamically configured by the base station.

[0183] In one embodiment of this disclosure, for example, if the initial frequency hopping position is determined to be n, and n encounters a problem of exceeding the system bandwidth of the lightweight UE, then n needs to be adjusted. In another embodiment of this disclosure, for example, if the initial frequency hopping position of the nth hop is determined to be a, and a exceeds the maximum system bandwidth supported by the lightweight UE, then the starting position of the frequency hopping of the nth hop can be the position b of the nmth hop, where b is within the system bandwidth range of the lightweight UE, and n > m. In this embodiment, m can be fixed by the protocol or dynamically configured by the base station. m is determined based on the number of frequency hopping cycles.

[0184] like Figure 4 The diagram shown illustrates the adjustment of the frequency hopping start position according to an embodiment of this disclosure. Figure 4 As shown, in Slot 3, since the bandwidth exceeds the UE's system bandwidth, adjustments are made, for example, by subtracting an adjustment value, such as 2, to bring it back into the system bandwidth of a lightweight UE. Similarly, for Slot 4, an adjustment value, such as 2, can also be subtracted.

[0185] In one embodiment of this disclosure, in response to the initial position of the start frequency hopping not exceeding the system bandwidth of the UE, the initial position of the start frequency hopping can be directly determined as the start position of frequency hopping.

[0186] In one embodiment of this disclosure, when the UE type is a non-lightweight UE, the frequency hopping parameter can be determined as the frequency hopping start position in the following manner.

[0187] In one embodiment of this disclosure, in response to the UE being a non-lightweight UE, the initial position of the start frequency hopping is taken as the start position of the frequency hopping.

[0188] In embodiments of this disclosure, the base station can inform the UE of the adjustment value by sending signaling to the UE. In one embodiment of this disclosure, the signaling may include Remaining Minimum System Information (RMSI) signaling.

[0189] Step 303: Perform frequency hopping according to the starting position of frequency hopping.

[0190] In one embodiment of this disclosure, after determining the frequency hopping start position, frequency hopping can be performed according to the frequency hopping start position.

[0191] In the embodiments of this disclosure, for a lightweight UE, its initial frequency hopping position is adjusted to determine the starting frequency hopping position corresponding to the lightweight UE, thereby avoiding jumping out of the system bandwidth range of the lightweight UE.

[0192] Figure 5 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure, executed by a UE. After determining frequency hopping parameters such as the frequency hopping offset value, the number of frequency hoppings, and the frequency hopping time-domain granularity, the UE can perform frequency hopping according to the determined parameters. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include the frequency hopping offset value, the number of frequency hoppings, and the frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the number of frequency hoppings is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; and the frequency hopping time-domain granularity is used to support cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0193] like Figure 5 As shown, in this embodiment, a corresponding formula for determining the frequency hopping start position can be set for the lightweight UE, thereby preventing the frequency hopping from exceeding the system bandwidth range of the lightweight UE. The frequency hopping control method includes the following steps:

[0194] Step 501: Determine the type of UE.

[0195] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, and a non-lightweight UE can be understood as a regular NR terminal that supports all NR features.

[0196] Step 502: Obtain the current frequency hopping count;

[0197] In the embodiments of this disclosure, different formulas are used for different frequency hopping counts, so it is necessary to determine the number of frequency hopping counts.

[0198] Step 503: Generate the current frequency hopping start position based on the current frequency hopping count;

[0199] In embodiments of this disclosure, for the UE, it can be The current frequency hopping start position is defined as i, where i is the current frequency hopping count, RBstart is the current frequency hopping start position, and RBoffset is the offset.

[0200] Step 504: Generate adjustment coefficients based on the UE type.

[0201] In embodiments of this disclosure, a corresponding adjustment coefficient is generated based on the type of UE, which can be used to adjust the current frequency hopping start position.

[0202] In one embodiment of this disclosure, for a non-lightweight UE, the adjustment factor is: in, The bandwidth portion (BWP) for non-lightweight UEs.

[0203] In one embodiment of this disclosure, for a lightweight UE, the adjustment factor can be generated based on the system bandwidth of the lightweight UE. In another embodiment of this disclosure, for a lightweight UE, the adjustment factor is... in, The bandwidth portion (BWP) for non-lightweight UEs. This refers to the system bandwidth for lightweight UEs.

[0204] In the embodiments of this disclosure, the adjustment coefficients generated based on the modulus can also be generated based on other methods, and this disclosure does not impose any limitations on this.

[0205] Step 505: Generate the frequency hopping start position based on the adjustment coefficient and the current frequency hopping start position.

[0206] In embodiments of this disclosure, the current frequency hopping start position is adjusted by adjusting the adjustment coefficient, thereby generating the frequency hopping start position.

[0207] Step 506: Perform frequency hopping according to the starting position of frequency hopping.

[0208] After the UE determines its corresponding frequency hopping start position, it performs frequency hopping according to the determined frequency hopping start position.

[0209] In this embodiment, the adjustment coefficient can be determined according to the type of UE, so that the lightweight UE can avoid exceeding the system bandwidth range of the lightweight UE.

[0210] In one embodiment of this disclosure, for a plurality of frequency hopping positions, the frequency hopping start position of a lightweight UE and a non-lightweight UE can be determined in the following manner.

[0211] For non-lightweight UEs, the frequency hopping start position can be calculated using the following formula:

[0212] Where i represents the number of frequency hopping.

[0213] For lightweight UEs, the frequency hopping start position can be calculated using the following formula:

[0214] Where i represents the number of frequency hopping.

[0215] In another embodiment of this disclosure, the starting position of frequency hopping can be determined by the following formula for intra-slot hopping and inter-slot hopping.

[0216] For non-lightweight UEs and intra-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0217]

[0218] For non-lightweight UEs, and for inter-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0219]

[0220] For lightweight UEs and intra-slot frequency hopping, the starting position for frequency hopping can be determined using the following formula:

[0221] Where i represents the number of frequency hopping.

[0222] For lightweight UEs and inter-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0223] Where i represents the number of frequency hopping.

[0224] In other embodiments of this disclosure, multiple frequency hopping can be performed. For example, for a lightweight UE, the starting position of frequency hopping can be determined by the following formula:

[0225] For lightweight UEs, multiple frequency hopping based on inter-slot frequency hopping:

[0226] Where i represents the number of frequency hopping.

[0227] For time-slot frequency hopping in lightweight UEs:

[0228] Where i represents the number of frequency hopping.

[0229] For frequency hopping between two time slots in lightweight UEs:

[0230] This is the current timeslot number.

[0231] The above embodiments can be used in scenarios where lightweight UEs support RF retuning between RAR and Msg3.

[0232] In embodiments of this disclosure, an adjustment coefficient is generated based on the minimum value between the system bandwidth of the lightweight UE and the frequency hopping start position (BWP) of the non-lightweight UE. In another embodiment of this disclosure, both the lightweight UE and the non-lightweight UE use the same formula for determining the frequency hopping start position. In this embodiment, since the formula used for both the lightweight UE and the non-lightweight UE is the same (both employ the formula for determining the frequency hopping start position of the lightweight UE as shown above), the base station does not need to distinguish between them. In yet another embodiment of this disclosure, an adjustment coefficient is generated based on the minimum value between the BWP of the non-lightweight UE and the system bandwidth of the lightweight UE, wherein the frequency hopping start position of both the non-lightweight UE and the lightweight UE is determined by this adjustment coefficient.

[0233] Figure 6 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure, executed by a UE. After determining frequency hopping parameters such as the frequency hopping offset value, the number of frequency hoppings, and the frequency hopping time-domain granularity, the UE can perform frequency hopping according to the determined parameters. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include the frequency hopping offset value, the number of frequency hoppings, and the frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the number of frequency hoppings is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; and the frequency hopping time-domain granularity is used to support cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0234] like Figure 6 As shown, in this embodiment, the frequency hopping parameter is the frequency hopping offset. In embodiments of this disclosure, the problem of hopping out of the lightweight UE's system bandwidth can also be avoided by adjusting the frequency hopping offset of the lightweight UE. This frequency hopping control method includes the following steps:

[0235] Step 601: Determine the type of UE.

[0236] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, and a non-lightweight UE can be understood as a regular NR terminal that supports all NR features.

[0237] Step 602: Determine the frequency hopping parameter as the frequency hopping offset based on the UE type.

[0238] In one embodiment of this disclosure, the frequency hopping offset can be determined first by obtaining the offset configuration table corresponding to the type of UE, then by obtaining the offset identifier indicated by the base station, and then by determining the frequency hopping offset based on the offset identifier and the offset configuration table corresponding to the type of UE.

[0239] In one embodiment of this disclosure, different offset configuration tables are set for different types of UEs.

[0240] In one embodiment of this disclosure, the offset configuration table may be specified by a protocol or may be notified by the base station via system messages.

[0241] In one embodiment of this disclosure, the same offset configuration table can be configured for both non-lightweight UEs and lightweight UEs, or different offset configuration tables can be configured for them. If the same offset configuration table is configured, it is necessary to prevent lightweight UEs from exceeding their own system bandwidth.

[0242] Step 603: Perform frequency hopping based on the frequency hopping offset.

[0243] The UE performs frequency hopping based on the frequency hopping offset determined in the above steps.

[0244] In the embodiments of this disclosure, the frequency hopping offset of a lightweight UE can be adjusted to avoid the lightweight UE from jumping out of the system bandwidth range.

[0245] In one embodiment of this disclosure, when the UE is a non-lightweight UE, the frequency hopping offset in the first offset configuration table corresponding to the non-lightweight UE is determined based on the BWP of the non-lightweight UE; when the UE is a lightweight UE, the frequency hopping offset in the second offset configuration table corresponding to the lightweight UE is determined based on the system bandwidth of the lightweight UE.

[0246] In this embodiment, for intra-slot frequency hopping, non-lightweight UEs can use the following first offset configuration table:

[0247]

[0248] Table 1

[0249] In this embodiment, for intra-slot frequency hopping, the lightweight UE can use the following second offset configuration table:

[0250]

[0251] Table 2

[0252] In one embodiment of this disclosure, Tables 1 and 2 can be fixed via a protocol. Alternatively, they can be configured into the UE via base station instructions.

[0253] In other embodiments of this disclosure, for inter-slot frequency hopping between two hops, a non-lightweight UE may use the following first offset configuration table:

[0254]

[0255] Table 3

[0256] In other embodiments of this disclosure, for inter-slot frequency hopping between two hops, a lightweight UE may use the following second offset configuration table:

[0257]

[0258]

[0259] Table 4

[0260] In one embodiment of this disclosure, in the offset configuration table, the frequency hopping offset corresponding to the non-lightweight UE is determined by the BWP of the non-lightweight UE, and the frequency hopping offset corresponding to the lightweight UE is determined by the minimum value between the BWP of the non-lightweight UE and the system bandwidth of the lightweight UE.

[0261] In one embodiment of this disclosure, the aforementioned offset configuration table can also be configured to the UE via system messages.

[0262] In embodiments of this disclosure, both non-lightweight UEs and lightweight UEs may use the second offset configuration table.

[0263] In one embodiment of this disclosure, an offset configuration table can also be set for multi-hops.

[0264] In other embodiments of this disclosure, for three-hop inter-slot frequency hopping, a non-lightweight UE may use the following first offset configuration table:

[0265]

[0266] Table 5

[0267] In other embodiments of this disclosure, for three-hop inter-slot frequency hopping, a lightweight UE may use the following second offset configuration table:

[0268]

[0269] Table 6

[0270] In the embodiments of this disclosure, the first offset configuration table 5 and the second offset configuration table 6 can be specified by a protocol or notified by a system message.

[0271] In embodiments of this disclosure, the first offset configuration table and the second offset configuration table are merged. This merged table applies to both lightweight UEs and non-lightweight UEs, as shown in the table below.

[0272]

[0273] Table 7

[0274] In one embodiment of this disclosure, multiple frequency hopping offset value configuration tables can be aggregated into a single large table, and then the first offset identifier can be used as an index value for retrieval. Since aggregating multiple frequency hopping offset value configuration tables into one table results in a long table, extended bits are needed in the corresponding dynamic signaling to indicate its index. These extended bits can reuse the TPC (Power Control) field from RARULgrant.

[0275] In one embodiment of this disclosure, when repetition is required, the coverage is poor and the terminal generally transmits at full power. At this time, the TPC (Power Control) field is invalid, so the TPC field can be reused as an extended bit (i.e., the first offset identifier).

[0276] In one embodiment of this disclosure, the base station may set a first offset configuration table and a second offset configuration table, or it may set either a first offset configuration table or a second offset configuration table. If the BWP is greater than the system bandwidth of the lightweight UE, then both the first offset configuration table and the second offset configuration table are configured in the base station. If the BWP is less than or equal to the system bandwidth of the lightweight UE, then only the first offset configuration table is configured in the base station, and the lightweight UE also uses this first offset configuration table.

[0277] In one embodiment of this disclosure, the base station may set a first offset configuration table and a second offset configuration table. Non-lightweight UEs use the first offset configuration table to determine the frequency hopping start position, while lightweight UEs use the second offset configuration table to determine the frequency hopping start position.

[0278] In one embodiment of this disclosure, if the aforementioned offset configuration table is notified by a system message, then in this embodiment only the second offset configuration table needs to be sent. Both non-lightweight UEs and lightweight UEs use the second offset configuration table to determine the frequency hopping start position. In this way, the base station does not need to distinguish between UE types.

[0279] In one embodiment of this disclosure, the offset can be set not only through the offset configuration table described above, but also through protocol settings or system message configuration of the base station.

[0280] Figure 7 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure. Executed by the UE, the method allows the UE to perform frequency hopping according to determined frequency hopping parameters, such as the frequency hopping offset value, the number of hopping cycles, and the frequency hopping time-domain granularity. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include the frequency hopping offset value, the number of hopping cycles, and the frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the number of hopping cycles is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; and the frequency hopping time-domain granularity is used to support cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0281] like Figure 7 As shown, in this embodiment, the frequency hopping parameter is the number of frequency hopping cycles. In embodiments of this disclosure, the problem of exceeding the system bandwidth of the lightweight UE can also be avoided by adjusting the number of frequency hopping cycles of the lightweight UE. This frequency hopping control method includes the following steps:

[0282] Step 701: Determine the type of UE.

[0283] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, and a non-lightweight UE can be understood as a regular NR terminal that supports all NR features.

[0284] Step 702: Determine the frequency hopping parameter as the number of frequency hopping steps based on the UE type.

[0285] In the embodiments of this disclosure, if the UE is a non-lightweight UE, the first frequency hopping count is used as the frequency hopping count of the non-lightweight UE; if the UE is a lightweight UE, the second frequency hopping count is used as the frequency hopping count of the lightweight UE, wherein the first frequency hopping count is greater than the second frequency hopping count.

[0286] In the embodiments of this disclosure, the number of frequency hopping supported by a non-lightweight UE is greater than the number of frequency hopping supported by a lightweight UE.

[0287] In the embodiments of this disclosure, the first frequency hopping count and the second frequency hopping count are indicated by the base station's RMSI, Random Access Response (RAR), or Downlink Control Information (DCI).

[0288] In embodiments of this disclosure, the first frequency hopping count and the second frequency hopping count are configured by the protocol or indicated by the base station. In one embodiment of this disclosure, the base station can broadcast the first frequency hopping count and the second frequency hopping count via RMSI.

[0289] In the embodiments of this disclosure, the number of frequency hopping cycles for non-lightweight UEs is indicated by the base station, while the number of frequency hopping cycles for lightweight UEs is specified by the protocol.

[0290] In another embodiment of this disclosure, it is determined whether the BWP of the non-lightweight UE is greater than the system bandwidth of the lightweight UE; if it is greater than the system bandwidth of the lightweight UE, then a first preset number is used as the frequency hopping number of the non-lightweight UE, and a second preset number is used as the frequency hopping number of the lightweight UE, wherein the first preset number is greater than the second preset number; if it is less than or equal to the system bandwidth of the lightweight UE, then the first preset number is used as the frequency hopping number of both the non-lightweight UE and the lightweight UE.

[0291] In another embodiment of this disclosure, a first indication count and a second indication count are received from the base station, wherein the first indication count is greater than the second indication count; if the BWP of the non-lightweight UE is greater than the system bandwidth of the lightweight UE, then the first indication count is used as the frequency hopping count of the non-lightweight UE, and the second indication count is used as the frequency hopping count of the lightweight UE.

[0292] In another embodiment of this disclosure, a third indication number is received from the base station. If the first BWP of the non-lightweight UE is less than or equal to the second BWP of the lightweight UE, the third indication number is used as the frequency hopping number for both the non-lightweight UE and the lightweight UE.

[0293] It should be noted that the first and second indication counts, or the third indication count, mentioned above are indicated by the base station's RMSI, Random Access Response (RAR), or Downlink Control Information (DCI).

[0294] In one embodiment of this disclosure, a preset value, such as 0, can also be set for the lightweight UE, meaning that frequency hopping is not performed for the lightweight UE.

[0295] In this embodiment, frequency hopping within a time slot or frequency hopping between time slots can be applied.

[0296] In one embodiment of this disclosure, the frequency hopping count for non-lightweight UEs can be configured by the base station, while the frequency hopping count for lightweight UEs can also be set to a fixed value. In one embodiment of this disclosure, the value configured by the base station can be greater than a preset value specified by the protocol for lightweight UEs.

[0297] Step 703: Perform frequency hopping based on the number of hopping attempts.

[0298] The UE performs frequency hopping based on the number of frequency hopping determined in the above steps.

[0299] In the embodiments of this disclosure, the frequency hopping number of a lightweight UE can be adjusted to avoid the lightweight UE from jumping out of the system bandwidth range.

[0300] Figure 8 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure, executed by a lightweight UE. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include a frequency hopping offset value, a frequency hopping count, and a frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the frequency hopping count is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; and the frequency hopping time-domain granularity is used to support cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0301] like Figure 8 As shown in this embodiment, adjustment can be made via radio frequency readjustment. The frequency hopping control method includes the following steps:

[0302] Step 801: Confirm the location of the next hop for the lightweight UE.

[0303] like Figure 9a The diagram shown is a schematic representation of radio frequency readjustment according to an embodiment of this disclosure. (Refer to...) Figure 9a As shown, the next hop time domain location for the lightweight UE is Slot3.

[0304] Step 802: If the frequency domain position of the next hop exceeds the frequency domain position of the current working bandwidth of the lightweight UE, radio frequency readjustment is performed so that the working bandwidth of the lightweight UE jumps to the frequency domain position of the next hop.

[0305] Further reference Figure 9a As shown, the next-hop frequency domain location of the lightweight UE exceeds the frequency domain location of its current operating bandwidth. Therefore, radio frequency realignment is required for the lightweight UE to shift its operating bandwidth to the frequency domain location of the next hop, for example... Figure 9a Slot 4 is one of them.

[0306] In embodiments of this disclosure, the radio frequency readjustment time interval is specified as a fixed value by the protocol or indicated by the base station.

[0307] In embodiments of this disclosure, the time interval is indicated by system messages, Media Access Control Unit (MAC CE), or DCI signaling.

[0308] like Figure 9b The diagram shown is another schematic of radio frequency readjustment according to an embodiment of this disclosure. A lightweight UE jumps from Hop#0 to Hop#1 via radio frequency readjustment.

[0309] In the embodiments of this disclosure, for frequency hopping within a time slot, if the radio frequency readjustment scheme of this disclosure is adopted, the allocation of PUSCH time domain resources can be such that the radio frequency readjustment time + the number of PUSCH characters is less than or equal to the preset number of characters, for example, 14.

[0310] In the above embodiments, when lightweight UEs and non-lightweight UEs share the BWP, this disclosure supports Msg3 transmission frequency hopping mechanisms for both lightweight UEs and non-lightweight UEs, including traditional intra-slot frequency hopping, inter-slot frequency hopping, and multi-hop inter-slot frequency hopping, as well as inter-slot frequency hopping schemes with enhanced time-domain granularity.

[0311] Figure 10 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure. Executed by the base station, the method allows the UE to perform frequency hopping according to determined frequency hopping parameters, such as the frequency hopping offset value, the number of hopping cycles, and the frequency hopping time-domain granularity. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include the frequency hopping offset value, the number of hopping cycles, and the frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the number of hopping cycles is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; and the frequency hopping time-domain granularity is used to support cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0312] like Figure 10 As shown, the frequency hopping control method includes the following steps:

[0313] Step 1010: Determine the type of UE.

[0314] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, and a non-lightweight UE can be understood as a regular NR terminal that supports all NR features.

[0315] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, while a non-lightweight UE can be understood as a regular NR terminal supporting all NR features. In LTE 4G systems, two major technologies, MTC (Machine-Type Communications) and NB-IoT (Narrowband Internet of Things), were proposed to support IoT services. These two technologies are mainly aimed at low-speed, high-latency scenarios, such as meter reading and environmental monitoring. Currently, NB-IoT can only support a maximum speed of a few hundred kilobytes per second, and MTC can only support a maximum speed of a few megabytes per second. However, on the other hand, with the continuous development of IoT services, such as video surveillance, smart homes, wearable devices, and industrial sensing and monitoring, these services typically require speeds of tens to 100 megabytes per second, while also having relatively high latency requirements. Therefore, the MTC and NB-IoT technologies in LTE are difficult to meet these requirements. In this embodiment, this new UE type is collectively referred to as Reducedcapability UE, or lightweight UE, while current ordinary terminals are referred to as non-lightweight UE in the embodiments of this disclosure.

[0316] In one embodiment of this disclosure, a lightweight UE typically has the following characteristics:

[0317] -Low cost, low complexity

[0318] - Some degree of coverage enhancement

[0319] - Power saving.

[0320] Since the current NR (New Radio) interface is designed for high-end terminals with high speed and low latency, it cannot meet the requirements of lightweight UEs. Therefore, the current NR system needs to be modified to meet the requirements of lightweight UEs. For example, to meet requirements such as low cost and low complexity, the bandwidth of lightweight UEs can be limited, such as to 10 MHz or 20 MHz, or the number of receiving antennas of lightweight UEs can be limited. For power saving, possible optimization directions include reducing the processing complexity of user equipment, such as receiving only the PDCCH (Physical Downlink Control Channel) channel in the same time slot, and entering a micro-sleep state at other symbol times in the same time slot. For a certain degree of coverage enhancement, multiple retransmissions of each channel can be performed, the aggregation level can be increased, and the code rate can be reduced.

[0321] In one embodiment of this disclosure, the UE type can be determined based on the bandwidth. In another embodiment, the base station can determine the UE's bandwidth and, based on that bandwidth, determine the UE's type: either a lightweight UE or a non-lightweight UE. In other embodiments of this disclosure, the two UE types can also be distinguished based on the physical random access channel (PRACH).

[0322] like Figure 2 As shown, in one embodiment of this disclosure, the frequency hopping offset value is used to determine the starting position of each hop; the number of frequency hopping can be understood as the number of hops: for example, Message3 is transmitted repeatedly 8 times, the time-domain granularity of frequency hopping is 1 slot, and the number of hops can be 4, then the frequency hopping mode can be as follows: Figure 2 As shown, that is, during the repetition process, the transmission of msg3 has four different frequency domain positions (such as...). Figure 2 (The gray part within).

[0323] Step 1020: Determine the frequency hopping parameters of the UE based on the UE type.

[0324] In embodiments of this disclosure, the frequency hopping parameters include one or more of the following: frequency hopping start position, frequency hopping offset, and frequency hopping count. In one embodiment of this disclosure, the frequency hopping parameters are determined based on the type of UE. Specifically, independent frequency hopping parameters can be set for lightweight UEs and non-lightweight UEs, making the frequency hopping parameters different for lightweight and non-lightweight UEs, thereby preventing lightweight UEs from hopping outside their system bandwidth during frequency hopping. In another embodiment of this disclosure, the same frequency hopping parameters can be set for both lightweight and non-lightweight UEs, but these parameters need to take into account lightweight UEs to prevent them from hopping outside their system bandwidth range. Alternatively, the frequency hopping parameters for non-lightweight UEs can be kept unchanged, while the frequency hopping parameters for lightweight UEs can be adjusted.

[0325] Step 1030: Provide frequency hopping service to the UE based on the determined frequency hopping parameters of the UE.

[0326] In embodiments of this disclosure, frequency hopping services can be provided to the UE based on the determined frequency hopping parameters of the UE.

[0327] Figure 11 This is a flowchart illustrating a frequency hopping control method provided in an embodiment of this disclosure, executed by a base station. It should be noted that in the embodiments of this disclosure, the frequency hopping parameters include a frequency hopping offset value, a number of frequency hopping operations, and a frequency hopping time-domain granularity. The frequency hopping offset value is used to determine the starting position of each hop; the number of frequency hopping operations is used to obtain higher frequency diversity gain by configuring multiple frequency domain positions; and the frequency hopping time-domain granularity is used to support cross-slot joint channel estimation by expanding the basic granularity of time-domain frequency hopping, or to reduce the DMRS (Demodulation Reference Signal) density for low-mobility or stationary UEs.

[0328] like Figure 11 As shown, in this embodiment, the frequency hopping parameter can be the frequency hopping start position. The frequency hopping control method includes the following steps:

[0329] Step 1110: Determine the type of UE.

[0330] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, and a non-lightweight UE can be understood as a regular NR terminal that supports all NR features.

[0331] In the embodiments of this disclosure, the UE type includes lightweight UE (reduced capability) and non-lightweight UE. In one embodiment of this disclosure, a lightweight UE can be understood as an IoT device with low bandwidth or a small number of antennas, while a non-lightweight UE can be understood as a regular NR terminal supporting all NR features. In LTE 4G systems, two major technologies, MTC (Machine-Type Communications) and NB-IoT (Narrowband Internet of Things), were proposed to support IoT services. These two technologies are mainly aimed at low-speed, high-latency scenarios, such as meter reading and environmental monitoring. Currently, NB-IoT can only support a maximum speed of a few hundred kilobytes per second, and MTC can only support a maximum speed of a few megabytes per second. However, on the other hand, with the continuous development of IoT services, such as video surveillance, smart homes, wearable devices, and industrial sensing and monitoring, these services typically require speeds of tens to 100 megabytes per second, while also having relatively high latency requirements. Therefore, the MTC and NB-IoT technologies in LTE are difficult to meet these requirements. In this embodiment, this new UE type is collectively referred to as Reducedcapability UE, or lightweight UE, while current ordinary terminals are referred to as non-lightweight UE in the embodiments of this disclosure.

[0332] In one embodiment of this disclosure, a lightweight UE typically has the following characteristics:

[0333] -Low cost, low complexity

[0334] - Some degree of coverage enhancement

[0335] - Power saving.

[0336] Since the current NR (New Radio) interface is designed for high-end terminals with high speed and low latency, the current design cannot meet the needs of lightweight terminals.

[0337] The aforementioned requirements of lightweight UEs necessitate modifications to the existing NR system to meet these requirements. For example, to achieve low cost and low complexity, the bandwidth of lightweight UEs can be limited, such as to 10 MHz or 20 MHz, or the number of receiving antennas can be restricted. Regarding power savings, potential optimizations include reducing the processing complexity of user equipment, such as receiving only the PDCCH (Physical Downlink Control Channel) in the same time slot, while entering a micro-sleep state during other symbols in the same time slot. For a certain degree of coverage enhancement, multiple retransmissions of various channels can be performed, aggregation levels can be increased, and the code rate can be reduced.

[0338] In one embodiment of this disclosure, the UE type can be determined based on the bandwidth. In another embodiment, the base station can determine the UE's bandwidth and, based on that bandwidth, determine the UE's type: either a lightweight UE or a non-lightweight UE. In other embodiments of this disclosure, the two UE types can also be distinguished based on the physical random access channel (PRACH).

[0339] like Figure 2 As shown, in one embodiment of this disclosure, the frequency hopping offset value is used to determine the starting position of each hop; the number of frequency hopping can be understood as the number of hops: for example, Message3 is transmitted repeatedly 8 times, the time-domain granularity of frequency hopping is 1 slot, and the number of hops can be 4, then the frequency hopping mode can be as follows: Figure 2 As shown, that is, during the repetition process, the transmission of msg3 has four different frequency domain positions (such as...). Figure 2 (The gray part within).

[0340] Step 1120: Determine the UE frequency hopping parameter as the frequency hopping start position according to the UE type.

[0341] In one embodiment of this disclosure, the frequency hopping start position can be determined in the same way for both non-lightweight UEs and lightweight UEs. However, for lightweight UEs, after determining the frequency hopping start position, it is necessary to adjust the frequency hopping start position of the lightweight UE to reduce it, thereby avoiding the situation where the frequency hopping exceeds the system bandwidth range of the lightweight UE.

[0342] In one embodiment of this disclosure, the frequency hopping parameter can be determined as the frequency hopping start position in the following manner.

[0343] In response to the UE being a lightweight UE, the initial position of the UE's initial frequency hopping is determined, and then the initial position of the UE's frequency hopping is determined based on the initial value of the UE's initial frequency hopping.

[0344] The adjustment value is determined in the following ways: either by protocol specification or by sending signaling configuration to the UE.

[0345] In one embodiment of this disclosure, the adjustment value can be fixed by a protocol or dynamically configured by the base station.

[0346] In embodiments of this disclosure, the system bandwidth of the UE is determined, and in response to the initial position of the start frequency hopping exceeding the system bandwidth of the UE, an adjustment value is obtained. Then, the initial position of the start frequency hopping is adjusted according to the adjustment value to generate the frequency hopping start position of the UE.

[0347] In one embodiment of this disclosure, in response to the initial position of the start frequency hopping not exceeding the system bandwidth of the UE, the initial position of the start frequency hopping is determined as the frequency hopping start position of the UE.

[0348] In one embodiment of this disclosure, for example, if the initial starting position of the frequency hopping is determined to be n, and n encounters a problem of exceeding the system bandwidth of the lightweight UE, then n needs to be adjusted. In another embodiment of this disclosure, for example, if the initial starting position of the frequency hopping for the nth hop is determined to be a, and a exceeds the maximum system bandwidth supported by the lightweight UE, then the starting position of the frequency hopping for the nth hop can be the position b of the nmth hop, where b is within the system bandwidth range of the lightweight UE, and n > m. In this embodiment, m can be fixed by the protocol or dynamically configured by the base station. m is determined based on the number of frequency hopping cycles.

[0349] like Figure 4 The diagram shown illustrates the adjustment of the frequency hopping start position according to an embodiment of this disclosure. Figure 4 As shown, in Slot 3, since the bandwidth exceeds the UE's system bandwidth, adjustments are made, for example, by subtracting an adjustment value, such as 2, to bring it back into the system bandwidth of a lightweight UE. Similarly, for Slot 4, an adjustment value, such as 2, can also be subtracted.

[0350] In one embodiment of this disclosure, in response to the UE being a non-lightweight UE, the initial position of the start frequency hopping is taken as the start position of the frequency hopping.

[0351] In embodiments of this disclosure, the base station can inform the UE of the adjustment value by sending signaling to the UE. In one embodiment of this disclosure, the signaling may include Remaining Minimum System Information (RMSI) signaling.

[0352] In the embodiments of this disclosure, the current frequency hopping count of the UE is obtained, the current frequency hopping start position of the UE is generated based on the current frequency hopping count, an adjustment coefficient is generated based on the type of the UE, and the frequency hopping start position of the UE is generated based on the adjustment coefficient and the current frequency hopping start position.

[0353] In embodiments of this disclosure, for the UE, it can be The current frequency hopping start position is defined as i, where i is the current frequency hopping count, RBstart is the current frequency hopping start position, and RBoffset is the offset.

[0354] In the embodiments disclosed herein, if the UE is a non-lightweight UE, the bandwidth portion (BWP) of the non-lightweight UE is obtained, and an adjustment coefficient is generated based on the BWP; if the UE is a lightweight UE, the system bandwidth of the lightweight UE is obtained, and an adjustment coefficient is generated based on the system bandwidth.

[0355] In one embodiment of this disclosure, for a non-lightweight UE, the adjustment factor is: in, The bandwidth portion (BWP) for non-lightweight UEs.

[0356] In one embodiment of this disclosure, for a lightweight UE, the adjustment factor can be generated based on the system bandwidth of the lightweight UE. In another embodiment of this disclosure, for a lightweight UE, the adjustment factor is... in, The bandwidth portion (BWP) for non-lightweight UEs. This refers to the system bandwidth for lightweight UEs.

[0357] In the embodiments of this disclosure, the adjustment coefficients generated based on the modulus can also be generated based on other methods, and this disclosure does not impose any limitations on this.

[0358] In embodiments of this disclosure, the adjustment coefficient can be generated based on the minimum value between the system bandwidth of the lightweight UE and the BWP of the non-lightweight UE.

[0359] In embodiments of this disclosure, an adjustment factor is generated based on the minimum of the BWP of the non-lightweight UE and the system bandwidth of the lightweight UE, wherein the frequency hopping start position of both the non-lightweight UE and the lightweight UE is determined by the adjustment factor.

[0360] Step 1130: Determine the UE frequency hopping parameter as the frequency hopping offset based on the UE type.

[0361] In the embodiments of this disclosure, an offset configuration table corresponding to the type of the UE is sent to the UE, and an offset identifier is sent to the UE.

[0362] The offset configuration table is determined in the following ways: either by protocol specification or by sending signaling configuration to the UE.

[0363] In one embodiment of this disclosure, different offset configuration tables are set for different types of UEs.

[0364] In one embodiment of this disclosure, the same offset configuration table can be configured for both non-lightweight UEs and lightweight UEs, or different offset configuration tables can be configured for them. Configuring the same offset configuration table can prevent lightweight UEs from exceeding their own system bandwidth.

[0365] In the embodiments of this disclosure, if the UE is a non-lightweight UE, the frequency hopping offset in the first offset configuration table corresponding to the non-lightweight UE is determined according to the BWP of the non-lightweight UE; if the UE is a lightweight UE, the frequency hopping offset in the second offset configuration table corresponding to the lightweight UE is determined according to the system bandwidth of the lightweight UE.

[0366] The frequency hopping offset in the second offset configuration table is determined based on the minimum value between the system bandwidth of the lightweight UE and the BWP of the non-lightweight UE.

[0367] In one embodiment of this disclosure, both non-lightweight UEs and lightweight UEs use a second offset configuration table.

[0368] In the embodiments of this disclosure, the frequency hopping offset corresponding to the non-lightweight UE is determined by the BWP of the non-lightweight UE, and the frequency hopping offset corresponding to the lightweight UE is determined by the minimum value between the BWP of the non-lightweight UE and the system bandwidth of the lightweight UE.

[0369] Step 1140: Determine the UE frequency hopping parameter as the number of frequency hopping steps based on the UE type.

[0370] In the embodiments of this disclosure, if the UE is a non-lightweight UE, the first frequency hopping count is used as the frequency hopping count of the non-lightweight UE; if the UE is a lightweight UE, the second frequency hopping count is used as the frequency hopping count of the lightweight UE, wherein the first frequency hopping count is greater than the second frequency hopping count.

[0371] Among them, the number of frequency hopping supported by non-lightweight UEs is greater than that supported by lightweight UEs.

[0372] The number of first frequency hopping and the number of second frequency hopping are configured by the protocol or indicated by the base station.

[0373] The first frequency hopping count and the second frequency hopping count are indicated by the base station's RMSI, Random Access Response (RAR), or Downlink Control Information (DCI).

[0374] In one embodiment of this disclosure, it is determined whether the BWP of the non-lightweight UE is greater than the system bandwidth of the lightweight UE. If it is greater than the system bandwidth of the lightweight UE, a first preset number of times is used as the frequency hopping number of the non-lightweight UE, and a second preset number of times is used as the frequency hopping number of the lightweight UE, wherein the first preset number of times is greater than the second preset number of times; if it is less than or equal to the system bandwidth of the lightweight UE, the first preset number of times is used as the frequency hopping number of both the non-lightweight UE and the lightweight UE.

[0375] In one embodiment of this disclosure, a first indication count and a second indication count are sent, wherein the first indication count is greater than the second indication count. If the BWP of the non-lightweight UE is greater than the system bandwidth of the lightweight UE, the first indication count is used as the frequency hopping count of the non-lightweight UE, and the second indication count is used as the frequency hopping count of the lightweight UE.

[0376] In one embodiment of this disclosure, a third indication number is transmitted, wherein if the first BWP of the non-lightweight UE is less than or equal to the second BWP of the lightweight UE, the third indication number is used as the frequency hopping number for both the non-lightweight UE and the lightweight UE.

[0377] It should be noted that the first and second indication counts, or the third indication count, mentioned above are indicated by the base station's RMSI, Random Access Response (RAR), or Downlink Control Information (DCI).

[0378] In one embodiment of this disclosure, a preset value, such as 0, can also be set for the lightweight UE, meaning that frequency hopping is not performed for the lightweight UE.

[0379] In the embodiments of this disclosure, the number of frequency hopping cycles for non-lightweight UEs is indicated by the base station, while the number of frequency hopping cycles for lightweight UEs is specified by the protocol.

[0380] Step 1050: Provide frequency hopping service to the UE based on the determined frequency hopping start position, frequency hopping offset, and frequency hopping count.

[0381] In the embodiments of this disclosure, after determining the frequency hopping start position, frequency hopping service can be performed according to the determined frequency hopping start position.

[0382] In this embodiment, the adjustment coefficient can be determined according to the type of UE, so that the lightweight UE can avoid exceeding the system bandwidth range of the lightweight UE.

[0383] In one embodiment of this disclosure, for a plurality of frequency hopping positions, the frequency hopping start position of a lightweight UE and a non-lightweight UE can be determined in the following manner.

[0384] For non-lightweight UEs, the frequency hopping start position can be calculated using the following formula:

[0385] Where i represents the number of frequency hopping.

[0386] For lightweight UEs, the frequency hopping start position can be calculated using the following formula:

[0387] Where i represents the number of frequency hopping.

[0388] In another embodiment of this disclosure, the starting position of frequency hopping can be determined by the following formula for intra-slot hopping and inter-slot hopping.

[0389] For non-lightweight UEs and intra-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0390]

[0391] For non-lightweight UEs, and for inter-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0392]

[0393] For lightweight UEs and intra-slot frequency hopping, the starting position for frequency hopping can be determined using the following formula:

[0394] Where i represents the number of frequency hopping.

[0395] For lightweight UEs and inter-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0396] Where i represents the number of frequency hopping.

[0397] In other embodiments of this disclosure, multiple frequency hopping can be performed. For example, for a lightweight UE, the starting position of frequency hopping can be determined by the following formula:

[0398] For lightweight UEs, multiple frequency hopping based on inter-slot frequency hopping:

[0399] Where i represents the number of frequency hopping.

[0400] For time-slot frequency hopping in lightweight UEs:

[0401] Where i represents the number of frequency hopping.

[0402] For frequency hopping between two time slots in lightweight UEs:

[0403] This is the current timeslot number.

[0404] The above embodiments can be used in scenarios where lightweight UEs support RF retuning between RAR and Msg3.

[0405] In the facts disclosed herein, after determining the frequency hopping offset, frequency hopping service is performed according to the frequency hopping offset.

[0406] In the embodiments of this disclosure, the frequency hopping offset of a lightweight UE can be adjusted to avoid the lightweight UE from jumping out of the system bandwidth range.

[0407] In one embodiment of this disclosure, when the UE is a non-lightweight UE, the frequency hopping offset in the first offset configuration table corresponding to the non-lightweight UE is determined based on the BWP of the non-lightweight UE; when the UE is a lightweight UE, the frequency hopping offset in the second offset configuration table corresponding to the lightweight UE is determined based on the system bandwidth of the lightweight UE.

[0437] In one embodiment of this disclosure, multiple frequency hopping offset value configuration tables can be aggregated into a single large table, and then the first offset identifier can be used as an index value for retrieval. Since aggregating multiple frequency hopping offset value configuration tables into one table results in a long table, extended bits are needed in the corresponding dynamic signaling to indicate its index. These extended bits can reuse the TPC (Power Control) field from RARULgrant.

[0438] In one embodiment of this disclosure, when repetition is required, the coverage is poor and the terminal generally transmits at full power. At this time, the TPC (Power Control) field is invalid, so the TPC field can be reused as an extended bit (i.e., the first offset identifier).

[0439] In one embodiment of this disclosure, the base station may set a first offset configuration table and a second offset configuration table, or it may set either a first offset configuration table or a second offset configuration table. If the BWP is greater than the system bandwidth of the lightweight UE, then both the first offset configuration table and the second offset configuration table are configured in the base station. If the BWP is less than or equal to the system bandwidth of the lightweight UE, then only the first offset configuration table is configured in the base station, and the lightweight UE also uses this first offset configuration table.

[0440] In one embodiment of this disclosure, the base station may set a first offset configuration table and a second offset configuration table. Non-lightweight UEs use the first offset configuration table to determine the frequency hopping start position, while lightweight UEs use the second offset configuration table to determine the frequency hopping start position.

[0441] In one embodiment of this disclosure, if the aforementioned offset configuration table is notified by a system message, then in this embodiment only the second offset configuration table needs to be sent. Both non-lightweight UEs and lightweight UEs use the second offset configuration table to determine the frequency hopping start position. In this way, the base station does not need to distinguish between UE types.

[0442] In one embodiment of this disclosure, the offset can be set not only through the offset configuration table described above, but also through protocol settings or system message configuration of the base station.

[0443] In the facts disclosed herein, after the UE determines the number of frequency hopping attempts, frequency hopping is performed according to the number of frequency hopping attempts.

[0444] In the embodiments of this disclosure, the frequency hopping number of a lightweight UE can be adjusted to avoid the lightweight UE from jumping out of the system bandwidth range.

[0445] Corresponding to the frequency hopping control methods provided in the above embodiments, this disclosure also provides a frequency hopping control device. Since the frequency hopping control device provided in this disclosure corresponds to the frequency hopping control methods provided in the above embodiments, the implementation of the frequency hopping control method is also applicable to the frequency hopping control device provided in this embodiment, and will not be described in detail in this embodiment. Figures 12-14 This is a schematic diagram of the frequency hopping control device proposed in this disclosure.

[0446] Figure 12This is a schematic diagram of the frequency hopping control device provided in an embodiment of this disclosure. The device is applied to a user equipment (UE).

[0447] like Figure 12 As shown, the frequency hopping control device 1200 includes: a first determining module 1201, a second determining module 1202, and a first processing module 1203, wherein:

[0448] The first determining module 1201 is configured to determine the type of the UE. In embodiments of this disclosure, the UE type includes a light UE (reduced capability) and a non-light UE. In one embodiment of this disclosure, a light UE can be understood as an IoT device with lower bandwidth or fewer antennas, and a non-light UE can be understood as a regular NR terminal supporting all NR features. In one embodiment of this disclosure, the UE type can be determined based on the bandwidth. In one embodiment of this disclosure, the base station can know the UE's bandwidth, and based on the UE's bandwidth, it can determine the UE type, i.e., a light UE or a non-light UE. In other embodiments of this disclosure, the two UE types can also be distinguished based on the physical random access channel (PRACH).

[0449] The second determining module 1202 is configured to determine frequency hopping parameters based on the type of the UE. In embodiments of this disclosure, the frequency hopping parameters include one or more of the following: frequency hopping start position, frequency hopping offset, and number of frequency hopping cycles. In one embodiment of this disclosure, the frequency hopping parameters are determined based on the type of the UE. Specifically, independent frequency hopping parameters can be set for lightweight UEs and for non-lightweight UEs, making the frequency hopping parameters different for lightweight and non-lightweight UEs, thereby preventing lightweight UEs from exceeding their system bandwidth during frequency hopping. In another embodiment of this disclosure, the same frequency hopping parameters can be set for both lightweight and non-lightweight UEs, but these parameters need to take into account lightweight UEs to prevent them from exceeding their system bandwidth range. Alternatively, the frequency hopping parameters for non-lightweight UEs can be kept unchanged, while the frequency hopping parameters for lightweight UEs can be adjusted.

[0450] The first processing module 1203 is configured to perform frequency hopping based on determined frequency hopping parameters. In embodiments of this disclosure, frequency hopping can be performed based on frequency hopping parameters determined by the UE. For example, frequency hopping can be performed based on the frequency hopping start position, frequency hopping offset, and the number of frequency hopping attempts.

[0451] In embodiments of this disclosure, frequency hopping parameters can be adjusted according to the type of UE, thereby avoiding situations where the frequency hopping exceeds the system bandwidth range of a lightweight UE.

[0452] In one embodiment of this disclosure, the frequency hopping parameter is the frequency hopping start position.

[0453] In one embodiment of this disclosure, the second determining module 1202 is configured to determine the initial starting frequency hopping position of the UE in response to the UE being a lightweight UE; and to determine the starting frequency hopping position based on the initial starting frequency hopping value.

[0454] In one embodiment of this disclosure, for example, if the initial frequency hopping position is determined to be n, and n encounters a problem of exceeding the system bandwidth of the lightweight UE, then n needs to be adjusted. In another embodiment of this disclosure, for example, if the initial frequency hopping position of the nth hop is determined to be a, and a exceeds the maximum system bandwidth supported by the lightweight UE, then the starting position of the frequency hopping of the nth hop can be the position b of the nmth hop, where b is within the system bandwidth range of the lightweight UE, and n > m. In this embodiment, m can be fixed by the protocol or dynamically configured by the base station. m is determined based on the number of frequency hopping cycles.

[0455] In one embodiment of this disclosure, in response to the initial position of the start frequency hopping not exceeding the system bandwidth of the UE, the initial position of the start frequency hopping can be directly determined as the start position of frequency hopping.

[0456] like Figure 4 The diagram shown illustrates the adjustment of the frequency hopping start position according to an embodiment of this disclosure. Figure 4 As shown, in Slot 3, since the bandwidth exceeds the UE's system bandwidth, adjustments are made, for example, by subtracting an adjustment value, such as 2, to bring it back into the system bandwidth of a lightweight UE. Similarly, for Slot 4, an adjustment value, such as 2, can also be subtracted.

[0457] In one embodiment of this disclosure, the second determining module 1202 is configured to determine the system bandwidth of the UE; in response to the initial position of the starting frequency hopping exceeding the system bandwidth of the UE, obtain an adjustment value, and adjust the initial position of the starting frequency hopping according to the adjustment value to generate the starting position of the frequency hopping.

[0458] In one embodiment of this disclosure, the second determining module 1202 is configured to determine the initial frequency hopping position as the frequency hopping start position in response to the initial frequency hopping position not exceeding the system bandwidth of the UE.

[0459] In one embodiment of this disclosure, the adjustment value is determined by: a protocol specification; or by signaling configuration sent by the base station.

[0460] In one embodiment of this disclosure, the second determining module 1202 is configured to take the initial frequency hopping position as the frequency hopping start position in response to the UE being a non-lightweight UE.

[0461] In one embodiment of this disclosure, the second determining module 1202 includes: a frequency hopping count acquisition unit configured to acquire the current frequency hopping count; a current frequency hopping start position generation unit configured to generate a current frequency hopping start position based on the current frequency hopping count; an adjustment coefficient generation unit configured to generate an adjustment coefficient based on the type of the UE; and a frequency hopping start position generation unit configured to generate the frequency hopping start position based on the adjustment coefficient and the current frequency hopping start position.

[0462] In embodiments of this disclosure, for the UE, it can be The current frequency hopping start position is defined as i, where i is the current frequency hopping count, RBstart is the current frequency hopping start position, and RBoffset is the offset.

[0463] In one embodiment of this disclosure, for a non-lightweight UE, the adjustment factor is: in, The bandwidth portion (BWP) for non-lightweight UEs.

[0464] In one embodiment of this disclosure, for a lightweight UE, the adjustment factor can be generated based on the system bandwidth of the lightweight UE. In another embodiment of this disclosure, for a lightweight UE, the adjustment factor is... in, The bandwidth portion (BWP) for non-lightweight UEs. This refers to the system bandwidth for lightweight UEs.

[0465] In the embodiments of this disclosure, the adjustment coefficients generated based on the modulus can also be generated based on other methods, and this disclosure does not impose any limitations on this.

[0466] In one embodiment of this disclosure, for a plurality of frequency hopping positions, the frequency hopping start position of a lightweight UE and a non-lightweight UE can be determined in the following manner.

[0467] For non-lightweight UEs, the frequency hopping start position can be calculated using the following formula:

[0468] Where i represents the number of frequency hopping.

[0469] For lightweight UEs, the frequency hopping start position can be calculated using the following formula:

[0470] Where i represents the number of frequency hopping.

[0471] In another embodiment of this disclosure, the starting position of frequency hopping can be determined by the following formula for intra-slot hopping and inter-slot hopping.

[0472] For non-lightweight UEs and intra-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0473]

[0474] For non-lightweight UEs and for inter-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0475]

[0476] For lightweight UEs and intra-slot frequency hopping, the starting position for frequency hopping can be determined using the following formula:

[0477] Where i represents the number of frequency hopping.

[0478] For lightweight UEs, and for inter-slot frequency hopping, the starting position of frequency hopping can be determined by the following formula:

[0479] Where i represents the number of frequency hopping.

[0480] In other embodiments of this disclosure, multiple frequency hopping can be performed. For example, for a lightweight UE, the starting position of frequency hopping can be determined by the following formula:

[0481] For lightweight UEs, multiple frequency hopping based on inter-slot frequency hopping:

[0482] Where i represents the number of frequency hopping.

[0483] For time-slot frequency hopping in lightweight UEs:

[0484] Where i represents the number of frequency hopping.

[0485] For frequency hopping between two time slots in lightweight UEs:

[0486] This is the current timeslot number.

[0487] The above embodiments can be used in scenarios where lightweight UEs support RF retuning between RAR and Msg3.

[0488] In embodiments of this disclosure, an adjustment coefficient is generated based on the minimum value between the system bandwidth of the lightweight UE and the frequency hopping start position (BWP) of the non-lightweight UE. In another embodiment of this disclosure, both the lightweight UE and the non-lightweight UE use the same formula for determining the frequency hopping start position. In this embodiment, since the formula used for both the lightweight UE and the non-lightweight UE is the same (both employ the formula for determining the frequency hopping start position of the lightweight UE as shown above), the base station does not need to distinguish between them. In yet another embodiment of this disclosure, an adjustment coefficient is generated based on the minimum value between the BWP of the non-lightweight UE and the system bandwidth of the lightweight UE, wherein the frequency hopping start position of both the non-lightweight UE and the lightweight UE is determined by this adjustment coefficient.

[0489] In one embodiment of this disclosure, the adjustment coefficient generation unit includes: an adjustment coefficient generation subunit configured to, if the UE is a non-lightweight UE, obtain the bandwidth portion (BWP) of the non-lightweight UE and generate adjustment coefficients based on the BWP; if the UE is a lightweight UE, obtain the system bandwidth of the lightweight UE and generate adjustment coefficients based on the system bandwidth.

[0490] In one embodiment of this disclosure, the system bandwidth subunit is configured to generate the adjustment coefficient based on the minimum of the system bandwidth of the lightweight UE and the BWP of the non-lightweight UE.

[0491] In one embodiment of this disclosure, the adjustment coefficient generation unit is configured to generate the adjustment coefficient based on the minimum value between the BWP of the non-lightweight UE and the system bandwidth of the lightweight UE, wherein the frequency hopping start position of both the non-lightweight UE and the lightweight UE is determined by the adjustment coefficient.

[0494] In one embodiment of this disclosure, the frequency hopping offset can be determined first by obtaining the offset configuration table corresponding to the type of UE, then by obtaining the offset identifier indicated by the base station, and then by determining the frequency hopping offset based on the offset identifier and the offset configuration table corresponding to the type of UE.

[0496] In one embodiment of this disclosure, the offset configuration table may be specified by a protocol or may be notified by the base station via system messages.

[0497] In one embodiment of this disclosure, the same offset configuration table can be configured for both non-lightweight UEs and lightweight UEs, or different offset configuration tables can be configured for them. Configuring the same offset configuration table can prevent lightweight UEs from exceeding their own system bandwidth.

[0498] In one embodiment of this disclosure, the system further includes: a first frequency hopping offset unit, configured such that if the UE is a non-lightweight UE, the frequency hopping offset in the first offset configuration table corresponding to the non-lightweight UE is determined based on the BWP of the non-lightweight UE; and a second frequency hopping offset unit, configured such that if the UE is a lightweight UE, the frequency hopping offset in the second offset configuration table corresponding to the lightweight UE is determined based on the system bandwidth of the lightweight UE.

[0500] In one embodiment of this disclosure, the offset configuration table is determined by: protocol specification; or by signaling configuration sent by the base station.

[0501] In one embodiment of this disclosure, one or more lists can be designed. For example, one list may include frequency hopping parameters such as frequency hopping offset value, frequency hopping count, and frequency hopping time-domain granularity. Alternatively, multiple lists may exist, each including one parameter. For instance, the first list may include the frequency hopping offset value, the second list may include the frequency hopping count, and the third list may include the frequency hopping time-domain granularity. This list can be specified by a protocol or notified via a system message, enabling the UE to obtain the list and subsequently retrieve at least one of the frequency hopping parameters, such as the frequency hopping offset value, frequency hopping count, and frequency hopping time-domain granularity, from one or more lists. Furthermore, the list can also be specified by communication protocols of communication standardization organizations (e.g., 3GPP, IEEE, etc.) or pre-configured in the communication device through factory settings. In one embodiment, when needed, the base station can send control signaling to the terminal, indicating the list to be applied in the current communication to notify the terminal to activate the list.

[0502] In one embodiment of this disclosure, both non-lightweight UEs and lightweight UEs use a second offset configuration table.

[0503] In one embodiment of this disclosure, in the offset configuration table, the frequency hopping offset corresponding to the non-lightweight UE is determined by the BWP of the non-lightweight UE, and the frequency hopping offset corresponding to the lightweight UE is determined by the minimum value between the BWP of the non-lightweight UE and the system bandwidth of the lightweight UE.

[0531]

[0532] Table 7

[0533] In one embodiment of this disclosure, multiple frequency hopping offset value configuration tables can be aggregated into a single large table, and then the first offset identifier can be used as an index value for retrieval. Since aggregating multiple frequency hopping offset value configuration tables into one table results in a long table, extended bits are needed in the corresponding dynamic signaling to indicate its index. These extended bits can reuse the TPC (Power Control) field from RARULgrant.

[0534] In one embodiment of this disclosure, when repetition is required, the coverage is poor and the terminal generally transmits at full power. At this time, the TPC (Power Control) field is invalid, so the TPC field can be reused as an extended bit (i.e., the first offset identifier).

[0535] In one embodiment of this disclosure, the base station may set a first offset configuration table and a second offset configuration table, or it may set either a first offset configuration table or a second offset configuration table. If the BWP is greater than the system bandwidth of the lightweight UE, then both the first offset configuration table and the second offset configuration table are configured in the base station. If the BWP is less than or equal to the system bandwidth of the lightweight UE, then only the first offset configuration table is configured in the base station, and the lightweight UE also uses this first offset configuration table.

[0536] In one embodiment of this disclosure, the base station may set a first offset configuration table and a second offset configuration table. Non-lightweight UEs use the first offset configuration table to determine the frequency hopping start position, while lightweight UEs use the second offset configuration table to determine the frequency hopping start position.

[0537] In one embodiment of this disclosure, if the aforementioned offset configuration table is notified by a system message, then in this embodiment only the second offset configuration table needs to be sent. Both non-lightweight UEs and lightweight UEs use the second offset configuration table to determine the frequency hopping start position. In this way, the base station does not need to distinguish between UE types.

[0551] In the embodiments of this disclosure, the first frequency hopping count and the second frequency hopping count are indicated by the base station's RMSI, Random Access Response (RAR), or Downlink Control Information (DCI).

[0552] In embodiments of this disclosure, the first frequency hopping count and the second frequency hopping count are configured by the protocol or indicated by the base station. In one embodiment of this disclosure, the base station can broadcast the first frequency hopping count and the second frequency hopping count via RMSI.

[0553] In the embodiments of this disclosure, the number of frequency hopping cycles for non-lightweight UEs is indicated by the base station, while the number of frequency hopping cycles for lightweight UEs is specified by the protocol.

[0554] In another embodiment of this disclosure, it is determined whether the BWP of the non-lightweight UE is greater than the system bandwidth of the lightweight UE; if it is greater than the system bandwidth of the lightweight UE, then a first preset number is used as the frequency hopping number of the non-lightweight UE, and a second preset number is used as the frequency hopping number of the lightweight UE, wherein the first preset number is greater than the second preset number; if it is less than or equal to the system bandwidth of the lightweight UE, then the first preset number is used as the frequency hopping number of both the non-lightweight UE and the lightweight UE.

[0555] In another embodiment of this disclosure, a first indication count and a second indication count are received from the base station, wherein the first indication count is greater than the second indication count; if the BWP of the non-lightweight UE is greater than the system bandwidth of the lightweight UE, then the first indication count is used as the frequency hopping count of the non-lightweight UE, and the second indication count is used as the frequency hopping count of the lightweight UE.

[0558] In one embodiment of this disclosure, a preset value, such as 0, can also be set for the lightweight UE, meaning that frequency hopping is not performed for the lightweight UE.

[0559] In this embodiment, frequency hopping within a time slot or frequency hopping between time slots can be applied.

[0560] In one embodiment of this disclosure, the frequency hopping count for non-lightweight UEs can be configured by the base station, while the frequency hopping count for lightweight UEs can be set to a fixed value.

[0561] Figure 13 This is a schematic diagram of the frequency hopping control device provided in an embodiment of this disclosure. The device is applied to a lightweight UE.

[0562] like Figure 13 As shown, the frequency hopping control device 1300 includes: a third determination module 1301 and a radio frequency readjustment module 1302, wherein:

[0563] The third determining module 1301 is configured to determine the location of the next hop for the lightweight UE. For example... Figure 9a The diagram shown is a schematic representation of radio frequency readjustment according to an embodiment of this disclosure. (Refer to...) Figure 9a As shown, the next hop position for the lightweight UE is Slot 3.

[0564] The radio frequency readjustment module 1302 is configured to perform radio frequency readjustment if the frequency domain position of the next hop exceeds the frequency domain position of the current operating bandwidth of the lightweight UE, so that the operating bandwidth of the lightweight UE jumps to the frequency domain position of the next hop. Further refer to... Figure 9a As shown, the next-hop position Slot 3 of the lightweight UE exceeds the frequency domain location of the lightweight UE's current operating bandwidth. Therefore, radio frequency realignment of the lightweight UE is required to shift its operating bandwidth to the frequency domain location of the next hop, for example... Figure 9a Slot 4 is one of them.

[0565] In one embodiment of this disclosure, the radio frequency readjustment time interval is specified as a fixed value by a protocol or indicated by a base station.

[0566] In one embodiment of this disclosure, the time interval is indicated by a system message, a Media Access Control Unit (MAC CE), or a DCI signaling.

[0567] like Figure 9b The diagram shown is another schematic of radio frequency readjustment according to an embodiment of this disclosure. A lightweight UE jumps from Hop#0 to Hop#1 via radio frequency readjustment.

[0568] In the embodiments of this disclosure, for frequency hopping within a time slot, if the radio frequency readjustment scheme of this disclosure is adopted, the allocation of PUSCH time domain resources can be such that the radio frequency readjustment time + the number of PUSCH characters is less than or equal to the preset number of characters, for example, 14.

[0576] In one embodiment of this disclosure, the fifth determining module 1402 is configured to determine the system bandwidth of the UE; in response to the initial position of the starting frequency hopping exceeding the system bandwidth of the UE, obtain an adjustment value; and adjust the initial position of the starting frequency hopping according to the adjustment value to generate the starting position of the frequency hopping of the UE.

[0577] In one embodiment of this disclosure, the fifth determining module 1402 is configured to determine the initial frequency hopping position as the frequency hopping start position of the UE in response to the initial frequency hopping position not exceeding the system bandwidth of the UE.
