Alternatively, the terminal 110 may be a device of an unmanned aerial vehicle. Alternatively, the terminal 110 may also be a vehicle-mounted device, for example, a vehicle computer with a wireless communication function, or a wireless terminal externally connected to the vehicle computer. Alternatively, the terminal 110 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 120 may be a network side device in a wireless communication system. The wireless communication system may include a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of a 5G system. Among them, the access network in the 5G system may be referred to as NG-RAN (New Generation-Radio access network).

The base station 120 may be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 120 adopts a centralized distributed architecture, it generally includes a Centralized Unit (CU) and at least two Distributed Units (DUs).

As shown in fig. 2, an information processing method, applied in a base station, includes:

s100: BWPs with different coverage characteristics are configured.

The base station may be any generation of base station, for example, but not limited to, a 5G base station.

The coverage characteristics of (a) may include: characteristics of uplink coverage and/or downlink coverage. For example, the uplink coverage is related to uplink transmission power of the UE, i.e., uplink reception with the base station. The downlink coverage is related to downlink transmission power of the base station, for example, downlink transmission power of downlink transmission from the base station to the UE.

Generally, the larger the coverage, the higher the transmit power of the corresponding link.

Here the different coverage characteristics may include:

different uplink coverage, different downlink coverage, alignment characteristics of uplink coverage and downlink coverage, or uplink coverage enhancement characteristics, downlink coverage enhancement characteristics, or enhancement characteristics of uplink coverage and downlink coverage. For example, there are BWP upstream and downstream overlays that are aligned, i.e., the upstream overlay is equal to the downstream overlay. Some BWPs upstream and downstream overlays are not aligned, i.e., upstream overlay is not equal to downstream overlay.

Some coverage has coverage enhancement characteristics through the configuration of the enhanced coverage resources, for example, if the uplink coverage is configured with the enhanced coverage resources, the corresponding uplink coverage has the uplink coverage enhancement characteristics, and if the downlink coverage is configured with the enhanced coverage, the corresponding downlink coverage has the downlink coverage enhancement characteristics.

The enhanced coverage resources here are: and more resources are allocated relative to the configuration without the enhanced coverage characteristic, so that the gain diversity of the base station is improved. Enhanced coverage resources herein include, but are not limited to: any one or more of time domain resources, frequency domain resources, spatial domain resources, and code domain resources.

Fig. 4A shows the transmit power with a single transmission at BWP 0-BWP 3. I.e., an overlay schematic in the case where BWP2 is not configured with an enhanced overlay resource.

Fig. 4B is a schematic diagram of BWP 0-BWP 3 configuring BWP2 with enhanced overlay resources to make BWP 0-BWP 3 overlay aligned as a whole in fig. 4A.

In this way, different UEs configure different BWPs, such that different UEs perform access and/or data transmission on the corresponding BWPs, and at the same time, have different uplink transmit powers and/or downlink receive powers during network access and/or data transmission.

Thus, BWPs with different coverage characteristics are available for UEs in different situations.

As shown in fig. 3, the method further comprises:

s110: configuring different part bandwidths BWP for different UEs; different BWPs have different coverage characteristics.

For example, the base station may configure different BWPs for different UEs according to the communication protocol in S110; at this time, since the communication protocol is also stored in the UE, the UE may determine the BWP configured for itself by the base station directly according to the communication protocol.

For another example, after configuring different BWPs for different UEs, the base station may issue BWP configuration information to the UEs, so that the subsequent UEs may determine the BWPs configured by the base station to the UEs according to the BWP configuration information.

The base station will be a different BWP for different UPs and different BWPs have different coverage characteristics. This is achieved by

For example, in some embodiments, the S110 may include:

configuring different BWPs for different types of UEs;

alternatively, the first and second electrodes may be,

different BWPs are configured for UEs in different locations.

The different types of UEs have different transmission capabilities, and in this case, configuring different BWPs for different types of UEs may include: configuring BWP used by the UE according to the transmitting capability of the UE.

The transmit capability of the UE may be embodied by a maximum transmit power of the UE. In this way, UEs with different transmission capabilities may be configured to use different BWPs, so that a UE with a weaker transmission capability may be allocated to a BWP with a smaller coverage, and a UE with a stronger transmission capability may be allocated to a BWP with a larger coverage; in this way, the BWP used by the UE is adapted to the transmit capabilities of the UE.

The transmission attenuation of uplink signals transmitted to the base station by the UEs in different locations is different, and in this case, configuring different BWPs for the UEs in different locations may include:

configuring uplink BWP with smaller uplink coverage for UE in the central zone of the cell, and configuring uplink BWP with larger uplink coverage for UE in the edge zone of the cell.

In some embodiments, the coverage characteristics include: and uplink coverage characteristics. For example, when the coverage characteristic is an uplink coverage characteristic, it indicates that different BWPs have different requirements for the transmit power of uplink transmission of the UE.

In another embodiment, different B WPs may have the same downstream coverage characteristics but different upstream coverage characteristics.

In some embodiments, the BWP comprises a first BWP and a second BWP, wherein the first BWP has no enhanced overlay resources; the second BWP has an enhanced overlay resource.

The first BWP and the second BWP herein may both be plural.

Here, the uplink transmission power of the first BWP is greater than the uplink transmission power of the second BWP.

In some embodiments, as shown in fig. 4, the S110 may include:

s111: configuring the first BWP for a first type of UE;

s112: configuring the second BWP for a second type of UE, wherein a transmit power level of the second type of UE is lower than a transmit power level of the first type of UE.

For example, the first type of UE may have a lower transmit power level than the second type of UE. For example, the first type of UE may be a conventional device with relatively high transmission power, such as a conventional mobile phone, a tablet computer, or a vehicle-mounted device. The second Type of UE may be a Machine Type Communication (MTC) device or an Internet of Things (IoT) device.

For another example, the first type of UE may be an MTC device or an IoT device, and the second type of UE may be a lightweight terminal that is lighter than the MTC device or the IoT device.

In this way, the transmission power level of the UE is adapted to the coverage characteristics of the BWP with which the UE is configured to use, and it can be ensured that UEs with different transmission power levels can use the corresponding BWP for wireless signal transmission.

In some embodiments, the enhanced coverage resource is configured to promote uplink coverage for the second type of UE to transmit uplink data using the second BWP.

By enhancing the allocation of the coverage resources, the base station has more uplink receiving gains, so that the overall coverage effect for a certain transmission reaches the expected value of the base station by enhancing the coverage resources for the second type of UE.

In some embodiments, the S110 may include at least one of:

configuring a time domain resource for repeated transmission for the second type of UE;

configuring frequency domain resources for frequency domain compression transmission for the second type of UE, wherein the frequency domain compression transmission is as follows: a data transmission method using the intermediate band of the second BWP;

configuring space domain resources of space domain diversity transmission for the second type of UE;

and configuring code domain resources of code domain spread spectrum transmission for the second type of UE.

And the repeatedly transmitted time domain resources obtain the time domain gain of the second type UE through the repeated transmission of the time domain.

The frequency domain compression transmission method is used, because the adjacent channel interference of the edge regions of different frequency bands is large, and the middle frequency band is a frequency band with weak adjacent channel interference, which is equivalent to that the edge frequency band outside the middle frequency band is used as an idle frequency band to ensure the quality of the received signal of the base station.

Spatial diversity transmission may use multiple beams to transmit the same data, respectively, to achieve spatial gain.

The spread spectrum transmission uses a bandwidth required for transmitting data than a bandwidth, which is equivalent to using more frequency domain resources than the original bandwidth for transmitting data, and at this time, more frequency domain resources and code domain resources are configured as enhanced transmission resources.

In some embodiments, the second BWP is configured with resource block RB clusters; wherein one of the RB clusters comprises: at least two RBs within the second BWP; wherein the frequency of different said RB clusters is different.

Multiple RBs may be allocated at the same time point on a BWP, and RBs located at different times and/or different frequency spectrums may be allocated during a period of time.

These RBs can be bundled to form an RB cluster.

In the embodiment of the present application, all RBs on one RB cluster have the same carrier frequency.

In some embodiments, the method further comprises:

and issuing the cluster configuration information of the RB cluster. Thus, after the UE receives the cluster configuration information, the cluster information of the RB cluster can be determined.

In some embodiments, the RB cluster includes: the RB cluster includes: a center RB cluster and an edge RB cluster; a portion of the edge RB clusters have carrier frequencies lower than the center RB cluster and another portion of the edge RB clusters have carrier frequencies higher than the center RB cluster;

the method further comprises the following steps:

configuring first transmission power for the center RB cluster and the edge RB cluster; wherein the transmit power of the center RB cluster is greater than the transmit power of the edge RB cluster.

A BWP may be divided into a plurality of sub-bands, and in some embodiments at least two RBs included in one RB cluster are located within the same sub-band. And one subband includes one or more carriers. The different sub-bands contain carriers with different carrier frequencies.

By distinguishing the edge RB cluster from the center RB cluster, the grouping and grouping scheduling of the RBs under different adjacent channel interference conditions are equivalently realized. In order to improve the signal transmission quality, the transmission power in the middle frequency band is made larger than that of the edge RB cluster, so that when the enhanced coverage resource is configured, the number of the enhanced coverage resource of the center RB cluster is smaller than that of the edge RB cluster.

Referring to fig. 5, RB clusters 1 to 6 may be a schematic configuration of RB clusters on a second BWP, with RB cluster 3 and RB cluster 4 being the center RB cluster; the RB cluster 1, RB cluster 2, RB cluster 5, and RB cluster 6 are all edge RB clusters. Wherein, the carrier frequencies of the RB cluster 1 and the RB cluster 2 are higher than the carrier frequencies of the RB cluster 3 and the RB cluster 4. The carrier frequencies of RB cluster 5 and RB cluster 6 are lower than the carrier frequencies of RB cluster 1 and RB cluster 2.

In some embodiments, the method further comprises:

and allocating the RB in the central RB cluster or the edge RB cluster to the target UE according to the position of the target UE which requests resource scheduling in the second type of UE.

On the other hand, different transmission powers are configured in the RB cluster, and resource-differentiated scheduling can be performed according to the position of the UE in the cell. For example, the cell edge has larger neighbor interference than the middle of the cell because it is adjacent to other cells. At this time, the resource scheduling is optimized by combining the position of the UE and the position of the RB cluster on the BWP, which is embodied in that on one hand, the spectrum utilization is improved, and on the other hand, the communication effect of using each frequency band to communicate the UE is ensured.

In some embodiments, the S120 may include:

when the target UE is located in a cell edge region, allocating one or more RBs in the central RB cluster for the target UE;

when the target UE is located in a cell center region, allocating one or more RBs in the edge RB cluster or the center RB cluster to the target UE;

wherein the cell edge region is located at a periphery of the cell center region.

In some embodiments, a cell range within a predetermined distance from the base station may be determined as a cell center region, and a cell range greater than the predetermined distance from the base station may be determined as a cell edge region.

In other embodiments, the cell center area and the cell edge area may be dynamically adapted, for example, the base station receives a plurality of UEs at different positions at the same time to request resource scheduling, and directly considers the position of one or more UEs closer to the base station as being in the cell center area; and the remaining UEs are considered to be in the cell edge area. As such, UEs closer to the base station can be dynamically allocated one or more RBs within the edge cluster of RBs, while URs further from the base station can be dynamically allocated one or more RBs within the center cluster of RBs.

FIG. 7 shows UE1 and UE 2; wherein UE1 is closer to the base station than UE 2. UE1 is located in the cell center region and UE2 is located in the cell edge region. The RBs that the UE1 prefers may be from one or more of RB cluster 1, RB cluster 2, RB cluster 5, and RB cluster 6 shown in FIG. 6. The UE2 preferentially uses RB cluster 3 and RB cluster 4 shown in fig. 6.

With the 5G netting deployed, the coverage problem is a significant challenge. Especially the coverage of high frequency bands. Under the same transmission power, the physical layer method for enhancing coverage generally includes repetition of transmission physical resources (retransmission), and ensuring transmission quality by using a smaller Modulation and Coding Scheme (MCS) and relay transmission.

For coverage problems of different types of UEs in the same network, it can also be considered to enhance coverage by different physical resource dedication.

Such as a specific BWP, is used to configure the UE of the enhanced coverage type, and the location of the allocated resource in the BWP also needs to consider coverage, i.e. the resource at the edge of the BWP may be sacrificed to enhance coverage of the intermediate resource.

Different BWPs (partial bandwidth) are covered differently, and the base station configures the communication resource of a certain BWP as a large coverage resource, for example, the communication resource corresponding to BWP2 in fig. 4A may be configured as more communication resources, and the communication resources corresponding to other BWPs may be configured as less communication resources than BWP 2. Thus BWP2 is a more configurable communication resource than other BWPs, i.e., an enhanced coverage resource that ensures communication quality.

And configuring the enhanced coverage resource of the repeated transmission in a time domain. That is, BWP2 resource adopts repetition technique, that is, the same resource transmits the same content repeatedly, for example, PDCCH repetition

Allocating frequency-hopping-transmitted frequency modulation codes in a frequency domain as enhanced coverage resources;

the transmission is compressed in the frequency domain configured in the frequency domain, so that the BWP2 edge positions are idle or used with less probability than the center region position, thereby realizing the enhanced coverage resource configuration.

Space resources for space multiplexing transmission are configured in a space domain to realize space diversity gain;

and configuring the spread spectrum code of spread spectrum transmission in a code domain as an enhanced coverage resource.

For the newly defined UE types, this is called: the light terminal has lower transmitting power level, the UE of the type reports the UE capability when accessing the network, the base station configures the capability UE to BWP2 according to the capability of the UE if the capability is corresponding, and meanwhile, the initial access bandwidth of the UE is also in BWP 2. The UE capability may be the capability of the UE type, or the capability subdivided under the type, such as the low power UE capability.

In some embodiments, power allocation within BWP2 is in terms of RB allocations, i.e., for low power UEs, UEs at the cell edge allocate RB resources that are powerful; small RB resources are allocated to relatively center UEs. The RB power here refers to the maximum transmit power allowed on the rbcuster. The RB cluster is a newly defined concept, and is mainly used to distinguish the maximum transmission power allowed on RBs.
