With The pursuit of speed, delay, high speed mobility, energy efficiency and The diversity and complexity of future life business, the third generation partnership project (The 3rd Generation Partnership Project,3GPP) international standards organization has begun to develop 5G for this purpose. The main application scenario of 5G is: enhanced mobile Ultra-wideband (Enhance Mobile Broadband, emmbb), low latency high reliability communications (Ultra-Reliable and Low Latency Communication, URLLC), large scale machine type communications (massive machine type of communication, mctc).

embbs still target users to obtain multimedia content, services, and data, and their demand is growing very rapidly. On the other hand, since the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the capability and demand of the eMBB are also relatively different, so that detailed analysis must be performed in connection with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

The NR can also be deployed independently, and a new radio resource control (Radio Resource Control, RRC) state, i.e., an rrc_inactive state, is defined in the 5G network environment for the purposes of reducing air interface signaling and quickly recovering radio connections and quickly recovering data traffic. This state is different from the rrc_idle and rrc_connected states.

In the rrc_idle state: mobility is cell selection reselection based on terminal equipment, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side does not have an Access Stratum (AS) context of the terminal equipment, and does not have RRC connection.

In the rrc_connected state: there is an RRC connection and the base station and the terminal device have a terminal device AS context. The network device knows that the location of the terminal device is cell specific. Mobility is mobility controlled by the network device. Unicast data may be transmitted between the terminal device and the base station.

Rrc_inactive: mobility is cell selection reselection based on terminal equipment, there is a connection between CN-NRs, terminal equipment AS context is present on a certain base station, paging is triggered by radio access network (Radio Access Network, RAN), RAN-based paging area is managed by RAN, network equipment knows that the location of terminal equipment is based on the paging area level of RAN.

To facilitate a better understanding of embodiments of the present application, a description will be given of a reduced capability (Reduced Capbility, redCap) terminal associated with the present application.

In release17 (R17), a RedCap terminal, or RedCap device, is introduced for use in a scenario with lower performance requirements. Such as but not limited to the following scenarios:

scene 1: an industrial wireless sensor (Industrial Wireless Sensors) has relatively low required latency and reliability compared to high reliability low latency communication (Ultra-Reliable and Low Latency Communication, URLLC) terminals. And, the device cost and power consumption are also lower than those of URLLC terminals and enhanced mobile ultra-wideband (Enhance Mobile Broadband, eMBB) terminals.

Scene 2: video monitoring (Video surveillance) can be used for video monitoring in smart city, industrial process and other scenes. In an intelligent city scene, the device is mainly used for data collection and processing, so that urban resources can be monitored and controlled more effectively, and more effective services are provided for urban residents.

Scene 3: wearable devices (Wearables). Including for example but not limited to smart watches, rings, electronic health devices, medical monitoring devices, etc. These devices are typically small in size.

Thus, the above scenario may have the following common requirements:

1. the equipment cost is lower than that of the eMBB terminal of release15 (release 15, R15) or release16 (release 16, R16).

In one possible implementation, the bandwidth of the device and the receive antennas may be reduced.

2. The device size requires smaller device sizes.

3. Coverage is required to achieve coverage comparable or close to that of the eMBB terminals of R15 or R16. In this case, if the coverage loss is caused by reducing the receiving antenna, reducing the bandwidth, reducing the power level or otherwise reducing the complexity of the terminal, a corresponding compensation is required.

For a better understanding of the embodiments of the present application, the cell reselection related to the present application will be described.

Cell reselection (cell reselection) refers to a process in which a terminal device provides a service signal by monitoring signal quality of a neighbor cell and a current cell in an idle mode to select a best cell. When the signal quality and level of the neighbor cell meet the S criterion and meet a certain reselection decision criterion (R criterion), the terminal will access the cell to camp on.

After the terminal equipment successfully resides, the cell measurement is continuously carried out. The RRC layer calculates an S criterion (Srxlev) according to the reference signal received power (Reference Signal Received Power, RSRP) measurement result, and compares it with a common frequency measurement start threshold (Sintrasearch) and a different frequency/different system measurement start threshold (snondintersearch) as a decision condition for whether to start neighbor cell measurement.

Measurement configuration: and for the same frequency (Intra-frequency) and different frequency (inter-frequency), the synchronous signal blocks (Synchronization Signal Block, SSB) with the configured frequency granularity assist the terminal equipment to measure (SS/PBCH block measurement timing configuration, SMTC) in measurement timing configuration, so as to achieve the purpose of terminal power saving.

Cell signal quality acquisition:

the system broadcasts a parameter N of frequency granularity and a threshold for selecting the best beam (beam).

The signal quality of the best N beams (beams) meeting the threshold is linearly averaged;

if there is no parameter N of the broadcast frequency granularity and no threshold, the signal quality of the best beam in the cell is the cell signal quality.

Target cell selection (R criterion): candidate cells are controlled by best cell range (rangeToBestCell), namely: and selecting the target cell after the most beam cell meeting the threshold from all candidate cells in the poor signal quality range of the best cell.

In order to facilitate a better understanding of the embodiments of the present application, the prior art and the problems associated with the present application will be described.

The network device may broadcast at most one white list (whistelist) and one black list (blacklist) for the same frequency in SIB3 and at most one white list (whistelist) and one black list (blacklist) for each different frequency point in SIB 4. The role of the whistelist is to assist the terminal device in cell reselection, i.e. if whistelist is configured, the terminal device can only select the target cell from whistelist. The role of the blacklist is to limit terminal device cell reselection, i.e. if the blacklist is configured, the terminal device cannot target cells in the blacklist.

After introducing the reduced capability (RedCap) terminal type, for the same cell, an operator may use different access restrictions for the RedCap and the Non-reduced capability (Non-RedCap) terminal (i.e., a common terminal), so that a whistest and a blacklist configured for the common terminal may not be suitable for the RedCap terminal any more, which affects cell reselection of the RedCap terminal and cannot achieve the purpose of network control.

Based on the above problems, the present application proposes a scheme for cell reselection of a RedCap terminal, and specific white list cell list and/or black list cell list are configured for the RedCap terminal, so as to improve the effect of cell reselection and/or cell measurement.

The technical scheme of the application is described in detail below through specific embodiments.

Fig. 2 is a schematic flow chart of a method 200 of wireless communication according to an embodiment of the application, as shown in fig. 2, the method 200 of wireless communication may include at least some of the following:

s210, the network equipment broadcasts cell information through a first SIB; wherein the cell information comprises at least one white list cell list and/or at least one black list cell list, and the cell information is configured according to terminal characteristics;

S220, the terminal equipment acquires the cell information by reading the first SIB.

In some embodiments, the terminal device may be a RedCap terminal, and the terminal device may also be a Non-RedCap terminal.

In some embodiments, the whitelisted cell list may include identification information of at least one neighbor cell, e.g., the whitelisted cell list may include a physical cell identification (Physical Cell Identifier, PCI) of at least one neighbor cell.

In some implementations, the whitelisted cell list can be represented by a starting neighbor cell PCI and a neighbor cell PCI Range (Range). For example, PCI 0+Range 3 indicates that the whitelisted cell list includes PCI 0, PCI 1, and PCI 2. As another example, PCI 1+Range 3 and PCI 5+Range 2 represent whitelisted cell lists including PCI 1, PCI 2, PCI 3, PCI 5 and PCI 6.

In some implementations, the blacklisted cell list can be represented by a starting neighbor cell PCI and a neighbor cell PCI Range (Range). For example, PCI 4+Range 3 indicates that the blacklisted cell list includes PCI 4, PCI 5, and PCI 6. As another example, PCI 0+Range 3 and PCI 5+Range 2 represent blacklisted cell lists including PCI 0, PCI 1, PCI 2, PCI 5 and PCI 6.

For example, the maximum MIMO layer number may be 1 or 2, i.e., the maximum MIMO layer number of the terminal device may be 1 or 2. Of course, the terminal device may have other number of maximum MIMO layers, which is not limited by the present application.

For example, the operating bandwidth may be 100MHz or 20MHz, that is, the operating bandwidth of the terminal device may be 100MHz or 20MHz, although the terminal device may also operate at other bandwidths, which is not limited by the present application.

In some embodiments, the first SIB is SIB 3 or SIB 4. Of course, the first SIB may be another SIB, which is not limited by the present application.

In some embodiments, for on-channel cell measurement or on-channel cell reselection, the first SIB is SIB 3; and/or, for inter-frequency cell measurement or inter-frequency cell reselection, the first SIB is SIB 4.

That is, in case the terminal device acquires the cell information by reading SIB 3, the cell information may be used for on-channel cell measurement or on-channel cell reselection. In case the terminal device acquires the cell information by reading SIB 4, the cell information may be used for inter-frequency cell measurement or inter-frequency cell reselection.

That is, the at least one white list cell list included in the cell information includes a white list cell list corresponding to each of the plurality of inter-frequency points. Similarly, the at least one blacklist cell list included in the cell information includes a blacklist cell list corresponding to each of the plurality of inter-frequency points.

it should be noted that, the information other than the inter freqcarrier freqlist-v17xy field in SIB 4 may be information in some existing standards, which is not described in detail in the present application.

In some embodiments, in case the cell information comprises the at least one white list cell list, the terminal device determines a target white list cell list from the at least one white list cell list according to its corresponding terminal characteristics; and/or, in case the cell information comprises the at least one blacklisted cell list, the terminal device determines a target blacklisted cell list from the at least one blacklisted cell list according to its corresponding terminal characteristics.

In some embodiments, the terminal device uses the cells in the target white list of cells as candidate cells for cell reselection in performing co-frequency cell reselection or inter-frequency cell reselection.

Specifically, for example, the terminal device only uses the cell in the target white list cell list as the candidate cell for cell reselection in the process of performing co-frequency cell reselection or inter-frequency cell reselection.

In particular, for another example, the terminal device preferentially uses the cells in the target white list cell list as candidate cells for cell reselection in the process of performing co-frequency cell reselection or inter-frequency cell reselection.

In some embodiments, the terminal device does not take the cell in the target blacklist of cells as a candidate cell for cell reselection in performing co-frequency cell reselection or inter-frequency cell reselection. That is, the terminal device excludes the cells in the target blacklist cell list in the process of performing the same-frequency cell reselection or different-frequency cell reselection.

In some embodiments, the terminal device performs cell measurements on cells in the target white list of cells during performing co-frequency cell reselection or inter-frequency cell reselection.

Specifically, for example, the terminal device only performs cell measurement on the cells in the target white list cell list in the process of performing co-frequency cell reselection or inter-frequency cell reselection.

For another example, the terminal device preferentially performs cell measurement on the cells in the target white list cell list in the process of performing co-frequency cell reselection or inter-frequency cell reselection.

In some embodiments, the terminal device does not make cell measurements for cells in the target blacklist of cells during performing co-frequency cell reselection or inter-frequency cell reselection. That is, the terminal device excludes the cells in the target blacklist cell list in the process of performing the same-frequency cell reselection or different-frequency cell reselection.

In the embodiment of the application, the network equipment can more flexibly assist the terminal equipment including the RedCap terminal to carry out cell reselection and neighbor cell measurement according to the terminal characteristics by broadcasting the information (namely the cell information) supported by the terminal equipment including the RedCap terminal by the neighbor cells related to the terminal characteristics of at least one terminal equipment, thereby being beneficial to terminal energy saving.

Therefore, in the embodiment of the application, the network device can configure at least one white list cell list and/or at least one black list cell list according to the terminal characteristics, so that the terminal device can determine a target white list cell list and/or a target black list cell list according to the corresponding terminal characteristics, and perform cell reselection and/or cell measurement based on the target white list cell list and/or the target black list cell list. Furthermore, for the RedCap terminal, the white list cell list and/or the black list cell list belonging to the RedCap terminal can be determined based on the corresponding terminal characteristics, and the RedCap terminal can perform cell reselection and/or cell measurement based on the white list cell list and/or the black list cell list, so that the cell reselection and/or cell measurement of the RedCap terminal are optimized, and the energy saving of the RedCap terminal is facilitated.
