Alternatively, the terminal 11 may be a roadside device, for example, a street lamp, a signal lamp or other roadside device with a wireless communication function.

The base station 12 may be a Network side device in a wireless Communication system, wherein the wireless Communication system may be the 4th Generation mobile Communication (4G) system, which is also called a long Term Evolution (L ong Term Evolution, L TE) system, or the wireless Communication system may be a 5G system, which is also called a New Radio, NR, or 5G NR system, or the wireless Communication system may be a next Generation system of the 5G system, wherein an Access Network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network) or a Machine Type Communication (MTC) system.

The base station 12 may be an evolved node b (eNB) used in a 4G system, or the base station 12 may also be a base station (gNB) using a centralized Distributed architecture in a 5G system, when the base station 12 uses the centralized Distributed architecture, the base station generally includes a Central Unit (CU) and at least two Distributed Units (DUs), the Central Unit is provided with a Protocol stack of a Packet Data Convergence Protocol (PDCP) layer, a Radio link layer Control Protocol (Radio L ink Control, R L C) layer, and a Media Access Control (MAC) layer, and the Distributed units are provided with a Physical (PHY) layer Protocol stack.

In the NR system, a carrier bandwidth may be divided into multiple BWPs, and a UE may be configured with multiple BWPs simultaneously, but the UE may have only one active downlink BWP at most and one active uplink BWP at the same time on a serving cell (but in case of two uplink carriers in a serving cell, there may be two active uplink carriers, and each uplink carrier has one active uplink BWP). If the UE is configured with multiple carriers, there may be one active uplink and downlink BWP on each carrier. For a paired spectrum containing an upstream carrier and a downstream carrier, the upstream BWP and the downstream BWP are independently configured; for unpaired spectrum with upstream and downstream on one carrier, the upstream BWP and the downstream BWP are the same BWP.

R15 NR supports the function that activated downlink BWP is inactive and falls back to default or initial BWP automatically for a while, the network can configure one initial BWP for each serving cell of UE, and one BWP inactivity timer (inactivity timer) is configured for each cell. If the BWP activity timer is configured for a cell, this means that the function of automatic fallback to default or initial BWP is turned on. If the function is turned on and inactivity over a period of time with the currently active BWP on the cell results in the BWP inactivity timer being started, the active cell automatically reverts to the default BWP and, if the default BWP is not configured, to the initial BWP. While the default BWP is considered a small bandwidth BWP for UE power saving.

The NR-L ite characteristic of R17 introduces a new type of terminal aiming at dealing with scenarios outside Enhanced Mobile Broadband (eMB)/high reliability and low latency (Ultra Reliable and L ow L energy Communication, UR LL C)/Internet of things Communication (Massive Machine Communication, mMTC), i.e. required rate, latency (delay), reliability under the condition that the above scenarios are not covered, for example, the rate is lower than the eMB but higher than the mBB requirement, and the requirements on latency and reliability are more relaxed than UR LL C, three typical application scenarios are factory sensors, video monitoring, wearable devices, so that the PDCCH introduced by the characteristic is a light weight UE. type of UE with the following characteristics of one, RX reduction, reduction from 4 of R15 to 2 or 1, two bandwidth reduction, a reduction of DCI size which is a value of a frequency allocation of DCI-II, DCI-II, DCI.

Based on the wireless communication system, how to realize the fast frequency hopping of the UE, the embodiments of the method are provided.

Fig. 2 is a flowchart illustrating a communication method according to an exemplary embodiment, which is used in a network device, such as a base station, and the network device can configure at least one bandwidth part (BWP) for a User Equipment (UE), as shown in fig. 2, and the communication method includes the following steps:

configuring, in step S11, frequency hopping configuration information corresponding to one or more bandwidth parts (BWPs) for a User Equipment (UE), the frequency hopping configuration information being associated with a frequency hopping pattern employed for frequency hopping on the one or more BWPs;

in step S12, the hopping configuration information is carried in a BWP handover command or a wake-up signal and sent to the UE.

In an embodiment of the present disclosure, the frequency hopping configuration information includes: a set of parameters associated with the frequency hopping pattern, or an indication information indicating the frequency hopping pattern.

In the embodiment of the present disclosure, the frequency hopping pattern includes one or more of where to start frequency hopping, a frequency hopping sequence and a frequency hopping interval.

In this way, dedicated signaling is not required to indicate the frequency hopping configuration information, and the frequency hopping configuration information is indicated based on the BWP handover command or the wake-up signal, so that the system signaling overhead can be reduced; meanwhile, the frequency hopping configuration information is carried in the BWP switching command or the wake-up signal, and the fast frequency hopping of the UE can be realized.

In some embodiments, configuring the UE with frequency hopping configuration information corresponding to one or more BWPs includes:

different hopping configuration information is configured for different UEs. That is, the hopping configuration information for different UEs may be different. For example, the hopping configuration information configured for different UEs may be different for the same BWP. In yet another example, the hopping configuration information configured for different UEs may also be the same for different BWPs.

That is, the hopping configuration information for different BWPs of the same UE may be different.

In some embodiments, the frequency hopping configuration information comprises a set of parameters associated with the frequency hopping pattern; step S12, including:

step S12a (not shown in fig. 2): sending a BWP handover command or a wake-up signal carrying a set of parameters associated with the frequency hopping pattern to the UE.

Wherein each group of parameters comprises one or more of the following parameters:

For example, the hopping sequence includes forward order hopping or reverse order hopping.

Illustratively, the basic unit of the frequency hopping of the UE is a sub-band (may be referred to as a sub-band). If the BWP bandwidth is 100M, the sub-band size is 5M. At this time, there are 20 sub-bands marked as 0-19 on BWP. The UE performs frequency hopping transmission within the BWP according to 5M, and according to a frequency hopping pattern, for example, the sub-bands hop in modulo 4 order, that is, the UE performs frequency hopping transmission at 0, 4, 8, 12, 16, 0; and another frequency hopping pattern, e.g., sub-bands, hops in modulo-4 reverse order, i.e., the UE hops for transmission at 16, 12, 8, 4, 0, 16. Here, modulo 4 denotes the hop interval.

Illustratively, if the hopping start position is subband 1, the hopping interval is 4, and the hopping is sequentially performed, the UE hops the transmission at 1, 5, 9, 13, 17, 1. For another example, if the hopping start position is subband 19 and the hopping interval is 4, the reverse order hopping is performed, i.e., the UE hops for transmission at 19, 15, 11, 7, 3, 19.

In this way, a set of parameters associated with the frequency hopping pattern is carried in the BWP handover command or the wake-up signal, the adjustment of the frequency hopping pattern of the UE is indicated based on the BWP handover command or the wake-up signal, and the frequency hopping pattern does not need to be indicated by dedicated signaling, which can reduce the overhead of system signaling and also achieve fast frequency hopping of the UE.

In some embodiments, the frequency hopping configuration information includes indication information indicating the frequency hopping pattern; step S12, including:

step S12b (not shown in fig. 2): and sending a BWP switching command or a wake-up signal carrying the indication information to the UE.

In this way, the BWP handover command or the wake-up signal carries indication information indicating a frequency hopping pattern, and the BWP handover command or the wake-up signal indicates to adjust the frequency hopping pattern of the UE, without using a dedicated signaling to indicate the frequency hopping pattern, which can reduce the overhead of the system signaling and achieve fast frequency hopping of the UE. In some embodiments, the method further comprises:

Illustratively, the set of candidate hopping parameters includes two sets of parameters, the first set of parameters corresponds to hopping pattern 1, the second set of parameters corresponds to hopping pattern 2, the first set of parameters corresponds to index 000, and the second set of parameters corresponds to index 100, so that the UE can determine the hopping pattern as hopping pattern 1 according to index 000 and determine the hopping pattern as hopping pattern 2 according to index 100.

In this way, it is convenient for the UE to store the set of frequency hopping candidate parameters sent by the network device in advance, and upon receiving a BWP handover command or a wake-up signal carrying an index value of the frequency hopping pattern sent by the network device, the UE can determine the frequency hopping pattern of the BWP according to the index value and the set of frequency hopping candidate parameters. Meanwhile, the network device is also convenient to indicate the frequency hopping pattern in the BWP handover command or the wake-up signal by carrying the index value of the frequency hopping pattern, so as to further reduce the size of the frequency hopping configuration information carried in the BWP handover command or the wake-up signal.

In some embodiments, the indication information comprises an index value of the hopping pattern in a hopping candidate parameter set; the step S12b includes:

step 12b1 (not shown in fig. 2): and sending a BWP switching command or a wake-up signal carrying the index value to the UE.

Therefore, when the UE determines the frequency hopping pattern corresponding to the indication information indicating the frequency hopping pattern, the UE can accurately determine the frequency hopping candidate parameter set, and the reliability of determining the frequency hopping pattern is improved. Meanwhile, the network device is also convenient to indicate the frequency hopping pattern in the BWP handover command or the wake-up signal by carrying the index value of the frequency hopping pattern, so as to further reduce the size of the frequency hopping configuration information carried in the BWP handover command or the wake-up signal.

In some embodiments, the frequency hopping configuration information further includes at least one of the following indication information:

indication information of starting or not starting frequency hopping;

It should be noted that the indication information may include, but is not limited to, the above-mentioned cases. Of course, the indication information may specifically include one or a combination of the above-mentioned items, and the like, and is not limited herein.

Next, a description will be given by taking, as an example, a case where the base station can carry, in a handover command instructing the UE to perform BWP handover, hopping configuration information used on a target BWP. a) As an embodiment, an index (index) of a certain set of hopping patterns in the candidate parameter set for hopping configuration of the UE is carried in the BWP handover command, so that the UE derives the hopping pattern of the target BWP according to the index. b) As an embodiment, the hopping pattern related parameters of the UE may be directly carried in the BWP handover command. c) As an embodiment, indication information of whether the frequency hopping pattern of the UE is enabled (enabled) or not (disabled) may be directly carried in the BWP handover command; d) as an example, not carrying any indication information in the BWP handover command means that no (Disable) hopping is enabled on the target BWP. e) As an embodiment, not carrying any indication information in the BWP handover command means that the hopping pattern on the target BWP follows the hopping pattern of the original BWP. f) As an embodiment, indication information of whether frequency hopping is for a control channel (PDCCH) or a traffic channel (PDSCH/PUSCH) may be carried in the BWP handover command.

In the following, a description will be given by taking as an example that the base station can carry, in a wake-up (Wakeup) command, the hopping configuration information used on the currently used BWP when waking up the UE. a) As an embodiment, an index (index) of a certain hopping pattern in the candidate parameter set for the UE's hopping configuration is carried in the wake-up command, so that the UE derives the hopping pattern of the target BWP according to the index. b) As an embodiment, the frequency hopping pattern related parameters of the UE may be directly carried in the wake-up command. c) As an embodiment, indication information of whether the frequency hopping pattern of the UE is enabled (enabled) or not (disabled) may be directly carried in the wake-up command. d) As an example, not carrying any indication information in the wake-up command means that no (Disable) frequency hopping is enabled on the target BWP. e) As an embodiment, indication information of whether frequency hopping is for a control channel (PDCCH) or a traffic channel (PDSCH/PUSCH) may be carried in the wake-up command.

In some embodiments, the method further comprises:

In some embodiments, the first indication information is transmitted via a broadcast message or dedicated signaling.

As such, for switching to the default BWP or the initial BWP scenario based on the inactivity timer timeout, the UE may be informed in advance of the frequency hopping pattern used by the default BWP or the initial BWP because there is no handover command instructing the UE to perform BWP switching at this time.

Illustratively, the default BWP or the initial BWP itself is narrow in bandwidth and likely not frequency hopped, and therefore, the UE may be notified in a broadcast message or dedicated signaling not to initiate frequency hopping in the default BWP or the initial BWP scenario, and thus not to initiate frequency hopping when the UE times out to the default BWP or the initial BWP scenario based on the inactivity timer.

With the technical solution of the present disclosure, configuring, for a UE, frequency hopping configuration information corresponding to one or more BWPs, where the frequency hopping configuration information is associated with a frequency hopping pattern used for frequency hopping on the one or more BWPs; carrying the frequency hopping configuration information on a BWP switching command or a wake-up signal and sending the BWP switching command or the wake-up signal to the UE; thus, compared to sending the frequency hopping configuration information through a special signaling, the frequency hopping configuration information is carried in the BWP handover command or the wake-up signal, which not only saves signaling overhead, but also changes the frequency hopping pattern by using the DCI indication of the non-data scheduling grant, which is helpful for implementing fast frequency hopping of the UE and obtaining the frequency diversity gain.

Fig. 3 is a flowchart illustrating a communication method according to an exemplary embodiment, where the communication method is used in a User Equipment (UE), and a network device, such as a base station, can configure at least one BWP for the UE, and the communication method includes the following steps:

in step S21, a BWP switch command or a wake-up signal is received;

determining, in step S22, frequency hopping configuration information corresponding to one or more BWPs according to the BWP handover command or the wake-up signal, the frequency hopping configuration information being associated with a frequency hopping pattern used for frequency hopping on the one or more BWPs;

in step S23, frequency hopping is performed on the one or more BWPs with the corresponding frequency hopping pattern.

In the embodiment of the present disclosure, the frequency hopping pattern includes where to start frequency hopping, a frequency hopping interval, and a frequency hopping sequence.

In this way, the frequency hopping configuration information is acquired from the BWP handover command or the wake-up signal, and the fast frequency hopping of the UE can be realized as opposed to acquiring the frequency hopping configuration information from the dedicated signaling.

In some embodiments, step S22, includes:

step 22a (not shown in fig. 3): in response to the BWP switch command or wake-up signal including a set of parameters associated with the frequency hopping pattern, determining a frequency hopping pattern for the one or more BWPs based on the set of parameters.

In this way, a set of parameters associated with the frequency hopping pattern is carried in the BWP handover command or the wake-up signal, and the frequency hopping pattern of the UE indicated by the base station is determined based on the set of parameters associated with the frequency hopping pattern carried in the BWP handover command or the wake-up signal, thereby enabling fast frequency hopping of the UE.

In some embodiments, step S22, includes:

step 22b (not shown in fig. 3): and in response to the BWP switching command or the wake-up signal comprising indication information indicating the frequency hopping pattern, determining a frequency hopping pattern corresponding to the one or more BWPs according to the indication information.

In some embodiments, the method further comprises:

the step S21 includes: step S21c (not shown in fig. 3): receiving a BWP handover command or a wake-up signal which is sent by the base station and carries the index value;

step S22 includes: step 22c (not shown in fig. 3): and determining a corresponding frequency hopping pattern of the index value according to the index value and the frequency hopping candidate parameter set.

In this way, the UE stores the set of candidate frequency hopping parameters sent by the network device in advance, and can determine the frequency hopping pattern of the UE indicated by the network device according to the index value and the set of candidate frequency hopping parameters when receiving the BWP handover command or the wake-up signal carrying the index value of the frequency hopping pattern sent by the network device, thereby achieving fast frequency hopping of the UE. Meanwhile, the network device is also convenient to indicate the frequency hopping pattern in the BWP handover command or the wake-up signal by carrying the index value of the frequency hopping pattern, so as to further reduce the size of the frequency hopping configuration information carried in the BWP handover command or the wake-up signal.
