Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of communication technology, and in particular to a BWP indication method, apparatus, communication device, and storage medium. Background Technology

[0002] To aggregate the use of continuous or discontinuous bandwidth, wireless communication technologies such as Long Term Evolution (LTE) or 5G New Radio (NR) employ carrier aggregation (CA). CA aggregates at least one component carrier together. To support diverse services and different types of terminals, 5G NR introduces the concept of a Bandwidth Part (BWP). A BWP is a continuous segment of bandwidth within a cell. 5G NR uses BWP to adaptively and flexibly adjust the size of the UE's receive and transmit bandwidth, ensuring that the user equipment's (UE) receive and transmit bandwidth does not need to be as large as the cell's bandwidth. For example, the following adaptive adjustment methods can be used: (1) When the UE is in a low-activity period, the base station can instruct the UE to reduce its working bandwidth through higher-layer signaling or downlink control information (DCI); (2) When the UE requires a large throughput, the base station can instruct the UE to increase its working bandwidth through higher-layer signaling or DCI; (3) The base station can instruct the UE to use different BWPs so that the position of the UE's working bandwidth can be moved in the frequency domain; (4) The base station can instruct different BWPs to use different subcarrier spacings.

[0003] A cell typically contains several consecutive or discontinuous frequency bands. If wireless communication technology uses CA (Clustered Access) to aggregate different frequency bands, this configuration has problems such as large latency and high signaling overhead. Summary of the Invention

[0033] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several user equipment 110 and several base stations 120.

[0034] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones (or "cellular" phones), and computers with IoT user equipment capabilities.

Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called a New Generation-Radio Access Network (NG-RAN).

[0036] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs).

[0041] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0042] like Figure 2 As shown, this disclosure provides a BWP indication method, executed by a network device, including:

[0043] Step S21: Send BWP indication information, wherein the BWP indication information indicates the BWP information contained in the associated frequency band.

[0044] In one embodiment, the network device may be an access network device or a core network device.

[0045] In one embodiment, the access network device may be, but is not limited to, a base station. The base station can be an interface device for the UE to access the Internet. The base station can be of various types; for example, it can be a 3G base station, a 4G base station, a 5G base station, or a base station using any generation of communication technology.

[0046] This disclosure provides a BWP indication method, executed by a user equipment, which may include: sending BWP indication information to the UE.

[0047] In one embodiment, the UE can be a variety of mobile terminals or fixed terminals. For example, the UE can be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform, or a multimedia device.

[0048] In one embodiment, the UE may include a non-connected UE or a connected UE; wherein, the non-connected UE includes: an inactive UE and / or an idle UE.

[0049] In one embodiment, the associated frequency band can refer to the frequency band associated with the cell. For example, one or more frequency bands contained in a cell can all refer to the frequency band associated with that cell.

[0050] In one embodiment, the associated frequency band can also refer to the frequency band associated with the UE. For example, the one or more frequency bands that the base station configures for the UE to use can all refer to the frequency band associated with the UE.

[0051] This disclosure provides a BWP indication method, executed by a network device, which may include: sending BWP indication information; wherein the BWP indication information indicates information about BWPs contained in an associated frequency band.

[0052] This disclosure provides a BWP indication method, executed by a network device, which may include: sending BWP indication information; wherein the BWP indication information indicates information about BWPs contained in multiple associated frequency bands.

[0053] In one embodiment, when there are multiple frequency bands, the multiple frequency bands can be consecutive frequency bands or discontinuous frequency bands.

[0054] In one embodiment, when there are multiple frequency bands, the multiple frequency bands include: an initial frequency band, which is the frequency band containing the initial BWP, and non-initial frequency bands, which are frequency bands other than the initial frequency band. For example, a cell includes frequency bands: frequency band 1, frequency band 2, and frequency band 3; wherein frequency band 1 contains the initial BWP, then frequency band 1 is the initial frequency band, and frequency bands 2 and 3 are non-initial frequency bands.

[0055] In one embodiment, the initial BWP can be the BWP used by the UE for initial access.

[0056] In one embodiment, the initial BWP can be the default BWP for the UE to implement the automatic BWP fallback function. Here, the automatic BWP fallback function means automatically switching from the currently active BWP to the default BWP. For example, if the BWP activated by the UE at a first moment is the first BWP, and the UE is inactive at a second moment, the UE can switch to the default BWP. In this embodiment, the UE can switch to the default BWP at the second moment or at any appropriate time to implement the automatic BWP fallback function; wherein the bandwidth of the first BWP is greater than that of the default BWP. In some implementations, the UE can implement the automatic BWP fallback function as early as the second moment.

[0057] In one embodiment, the BWP ID of the initial BWP is different from the BWP ID of any BWP other than the initial BWP in the cell. The ID here can be any one or more characters; the character can be at least one of letters, numbers, and symbols; for example, the identifier of the initial BWP can be BWP0.

[0058] For example, the BWP ID of the initial BWP can be BWP0; then, BWPs other than the initial BWP in the cell can be identified in a predetermined order; for example, it can be BWP1, BWP2, ..., BWPn; where n is an integer greater than 0. This predetermined order can be, but is not limited to, identification from low-frequency BWPs to high-frequency BWPs, or identification from high-frequency BWPs to low-frequency BWPs.

[0059] In one embodiment, the information of the BWP includes, but is not limited to, at least one of the following: BWP index, starting BWP index, index of the initial BWP, and number of BWPs. The BWP index here can refer to the ID of any BWP in any frequency band. The starting BWP here is the first numbered BWP in the frequency band; for example, in the initial frequency band, the starting BWP index can refer to the index of the initial BWP; in a non-initial frequency band, the starting BWP index can refer to the first numbered BWP in that non-initial frequency band.

[0060] Thus, in this embodiment of the disclosure, by knowing the BWP index of each BWP in the cell-associated frequency band, or by knowing the initial BWP index and number of BWPs in each frequency band, the number of each BWP in the cell-associated frequency band can be determined; thereby facilitating the network side's accurate scheduling of each BWP in each frequency band within the cell.

[0061] In one embodiment, BWP indicates frequency band information.

[0062] This disclosure provides a BWP indication method, executed by a network device, which may include: sending BWP indication information; wherein the BWP indication information indicates the frequency band information of the associated frequency band and the BWP information contained in the frequency band.

[0063] In one embodiment, the frequency band information includes, but is not limited to, a frequency band index. The frequency band index here includes, but is not limited to, an initial frequency band index and / or a non-initial frequency band index. The frequency band index here may also refer to a frequency band ID; this ID may also refer to any one or more characters.

[0064] Thus, in this embodiment, by knowing the frequency band index and other frequency band information associated with each cell, the number of the associated frequency band can be determined, which is beneficial for the network side to accurately schedule each frequency band. Furthermore, if the frequency band index and the BWP index of the BWP contained in the frequency band are known, it is also possible to accurately know which BWP is in which frequency band, thereby knowing which frequency band the BWP belongs to and further facilitating the network side's scheduling of each BWP.

[0065] In this embodiment, a network device can send BWP indication information to the UE, wherein the BWP indication information indicates the BWP information contained in the associated frequency band; this allows the UE to know the BWP information contained in the frequency bands within the cell. Thus, when the network needs to schedule BWPs for each frequency band within the cell to the UE, it can do so by sending indication information indicating the BWPs; thereby reducing signaling overhead and lowering the latency for the network to configure BWPs for the UE; and improving the accuracy of the UE's knowledge of the configured BWPs.

[0066] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0067] like Figure 3 As shown in the embodiments of this disclosure, a BWP indication method is executed by a network device, including:

[0068] Step S31: Send a first type of BWP index, wherein the first type of BWP index is a BWP ID obtained by uniformly numbering all BWPs in the cell; or, send a second type of BWP index, wherein the second type of BWP index includes at least a frequency band index and a BWP ID obtained by numbering the BWPs contained in the frequency band indicated by the frequency band index.

[0069] The first type of BWP index here can refer to the BWP ID of at least one BWP among the BWP IDs obtained by uniformly numbering all BWPs in the cell. For example, the first type of BWP index can refer to at least one of the following: the BWP ID of the initial BWP, the BWP ID of any one or more BWPs other than the initial BWP, the BWP ID of the initial BWP, and the BWP ID of any one or more BWPs other than the initial BWP.

[0070] The second type of BWP index here can refer to at least one of the following: the frequency band index of any frequency band in all frequency bands within the cell and the BWP ID of any BWP or multiple BWPs in that frequency band; the frequency band index of the initial frequency band and the BWP ID of the initial BWP; or the frequency band index of the initial frequency band and the BWP ID of any one or more BWPs other than the initial BWP in the initial frequency band.

[0071] In one embodiment, the BWP indication information includes: a first type of BWP index or a second type of BWP index; wherein, the first type of BWP index is: a BWP ID obtained by uniformly numbering all BWPs in the cell; the second type of BWP index includes at least: a frequency band index and a BWP ID obtained by numbering the BWPs contained in the frequency band indicated by the frequency band index.

[0072] In some embodiments of this disclosure, the BWP indication information is the same as the BWP indication information in step S21.

[0073] In this embodiment, a first type of BWP index can be sent by the network device to indicate the unified numbering of each BWP within the cell, or a second type of BWP index can be sent by the network device to indicate the independent numbering of each BWP in each frequency band within the cell. This allows the network side to schedule BWPs in each frequency band within the cell simply by sending either the first or second type of BWP index for the BWP to be scheduled. This reduces signaling overhead and lowers the latency for the network side to configure BWPs for the UE, while also improving the accuracy of the UE's knowledge of the configured BWPs.

[0074] In one embodiment, the first type of BWP index included in the BWP indication information is: the BWP ID of the starting BWP contained in the frequency band associated with the BWP indication information;

[0075] The BWP indication information also includes the number of BWPs contained in the frequency band associated with the BWP indication information.

[0076] For example, the frequency band associated with the cell includes frequency band 1. Frequency band 1 has one initial BWP, and the BWP PID of the initial BWP is BWP0; frequency band 1 includes a total of 3 BWPs. Therefore, the numbers of all BWPs in the frequency band associated with the cell can be determined based on the initial BWP and the number of BWPs in frequency band 1. For example, the numbers of all BWPs in the frequency band associated with the cell could be BWP0, BWP1, and BWP2.

[0077] For example, the frequency bands associated with a cell include frequency band 1 and frequency band 2. Frequency band 1 has one initial BWP with BWP ID BWP0; frequency band 1 has 3 BWPs and frequency band 2 has 2 BWPs, so the total number of BWPs in frequency bands 1 and 2 is 5. Therefore, the BWP numbers of the frequency bands associated with the cell can be determined based on the initial BWP and the sum of the number of BWPs in frequency bands 1 and 2. For example, the BWP numbers of all the BWPs associated with the cell could be BWP0, BWP1, BWP2, BWP3, and BWP4.

[0078] Thus, in this embodiment of the disclosure, by determining the BWP ID of the starting BWP in the associated frequency band within the cell and the number of BWPs included in the association, i.e., by using a first-type index and the number of BWPs, a unified numbering indication for all BWPs within the cell can be achieved. This facilitates the network side in scheduling all BWPs in the associated frequency band based on this unified numbering.

[0079] In one embodiment, the first type of BWP index included in the BWP indication information associated with the initial frequency band is: the BWP ID of the initial BWP;

[0080] The first type of BWP index included in the BWP indication information associated with non-initial frequency bands is the BWP ID of BWPs other than the initial BWP.

[0081] For example, the frequency band associated with a cell includes an initial BWP and BWPs other than the initial BWP; wherein, the BWP ID of the initial BWP is BWP0, and the BWP IDs of the BWPs other than the initial BWP are BWP1, BWP2, and BWP4, respectively. Based on the BWP ID of the initial BWP and the BWP IDs of the BWPs other than the initial BWP, the BWP number of the frequency band associated with the cell can be determined.

[0082] Thus, in this embodiment, the BWP ID of the initial BWP in the associated frequency band within the cell and the BWP IDs of other BWPs can be determined. This means that a unified numbering system for all BWPs within the cell can be implemented using the first type of BWP index. This facilitates network-side scheduling of all BWPs associated with the cell based on this unified numbering.

[0083] In one embodiment, the response to BWP indication information includes: a second type of BWP index;

[0084] The BWP ID of each BWP in the initial frequency band starts from the first value, where the first value is the BWPID of the initial BWP;

[0085] The BWP ID of each BWP in the non-initial frequency band starts from the second value, where the second value is different from the first value.

[0086] For example, the first value can be "0", which can be the BWP ID of the initial BWP; then the BWP IDs of the BWPs in the initial frequency band can be "0", "1", "2", "3", etc. The second value can be "1", then the BWP IDs of each BWP in each non-initial frequency band can be "1", "2", "3", and "4", etc.

[0087] For example, the first value can be "00", which can be the BWP ID of the initial BWP; then the BWP IDs of the BWPs in the initial frequency band can be "00", "01", "02", "03", etc. The second value can be "11", then the BWP IDs of each BWP in each non-initial frequency band can be "11", "12", "13", and "14", etc.

[0088] For example, the frequency bands associated with a cell include frequency band 1, frequency band 2, and frequency band 3; the frequency band indices of frequency band 1, frequency band 2, and frequency band 3 can be "S1", "S2", and "S3", respectively; where "S1" is the initial frequency band, and "S2" and "S3" are both non-initial frequency bands. Frequency band 1, frequency band 2, and frequency band 3 can then be independently numbered; the IDs of the four BWPs in frequency band 1 can be "0", "1", "2", and "3", respectively; the IDs of the four BWPs in frequency band 2 can be "1", "2", "3", and "4", respectively; and the IDs of the three BWPs in frequency band 3 can be "1", "2", and "3", respectively.

[0089] Thus, in this embodiment, each frequency band associated with a cell can be numbered, and the indication of each frequency band can be determined through its frequency band index. Furthermore, each frequency band associated with a cell can be numbered separately; for example, the IDs of each BWP within the initial frequency band can be numbered starting from a first value, and the IDs of each BWP outside the initial frequency band can be numbered starting from a second value. In this way, a second type of index can be used to indicate the independent number of each BWP contained in each frequency band within the cell, thereby facilitating the network side's scheduling of each BWP in each frequency band associated with the cell based on this independent number.

[0090] In one embodiment, the frequency band information includes: a frequency band index;

[0091] In the indication fields used in the BWP indication information, one indication field is used to indicate one frequency band index, or one indication field is used to indicate multiple frequency band indices.

[0092] In one embodiment, when an indicator field is used to indicate multiple frequency band indices, different bit values ​​of the indicator field indicate indices of different frequency band sets.

[0093] The BWP indication information here uses one or more indication fields. An indication field can be one or more digits.

[0094] For example, one indication field is used to indicate a frequency band index. For instance, if the BWP indication information uses three indication fields, these three fields are the first indication field, the second indication field, and the third indication field. When all bits of the first indication field are "1", it indicates the frequency band index of frequency band 1; when all bits of the first indication field are "0", it does not indicate the frequency band index of any frequency band. When all bits of the second indication field are "1", it is used to indicate the frequency band index of frequency band 2; when all bits of the second indication field are "0", it does not indicate the frequency band index of any frequency band. When all bits of the third indication field are "1", it is used to indicate the frequency band index of frequency band 3; when all bits of the third indication field are "0", it does not indicate the frequency band index of any frequency band.

[0095] For example, one indicator field can be used to indicate multiple band indices. For instance, if the BWP indicator information uses three indicator fields, these three fields are the first indicator field, the second indicator field, and the third indicator field. When all bits of the first indicator field are "1", it indicates the band index of the set of bands 1 and 2; when all bits of the first indicator field are "0", it does not indicate the band index of any band. When all bits of the second indicator field are "1", it indicates the band index of the set of bands 3 and 4; when all bits of the second indicator field are "0", it does not indicate the band index of any band. When all bits of the third indicator field are "1", it indicates the band index of the set of bands 5, 6, and 7; when all bits of the third indicator field are "0", it does not indicate the band index of any band.

[0096] In the above example, when an indicator field indicates multiple frequency band indices, different bit values ​​can be used to indicate the frequency band indices of different frequency bands. For example, if the first indicator field is 32 bits, then: when bits 1 to 16 of the first indicator field are "1" and bits 17 to 32 are "0", it indicates the frequency band index of frequency band 1; when bits 1 to 16 of the first indicator field are "0" and bits 17 to 32 are "1", it indicates the frequency band index of frequency band 2; when all bits of the first indicator field are "0", it does not indicate the frequency band index of any frequency band.

[0097] In the example above, when an indicator field indicates multiple band indices, different bit values ​​can indicate the indices of different band sets. For example, when bits 1 to 16 of the first indicator field are "1" and bits 17 to 32 are "0", it indicates the band indices of band sets 1 and 2; when bits 1 to 16 of the first indicator field are "0" and bits 17 to 32 are "1", it indicates the band indices of band sets 3 and 4; when all bits of the first indicator field are "0", it does not indicate the band indices of any band set.

[0098] In one embodiment, when an indicator field indicates the frequency band index of multiple frequency bands, it can indicate the frequency band index of multiple consecutive frequency bands, or it can indicate multiple non-consecutive frequency band indexes.

[0099] In the embodiments of this disclosure, one indicator field can be used to indicate one frequency band index, achieving independent indication of the frequency band index; alternatively, one indicator field can be used to indicate multiple frequency band indices, achieving joint indication of the frequency band indices. Thus, when an independent indication of a frequency band index is achieved through an indicator field, a one-to-one correspondence between the indicator field and the frequency band index can be established, making the indication more accurate and clear. Alternatively, when a joint indication of frequency band indices is achieved through an indicator field, multiple frequency band indices can be indicated through one indicator field, thereby saving bit overhead and thus reducing the signaling overhead and storage resource overhead for network devices and UEs in transmitting indication information.

[0100] In one embodiment, the information of the BWP includes: a BWP index;

[0101] In the indication fields used in BWP indication information, one indication field is used to indicate one BWP index, or one indication field is used to indicate multiple BWP indexes.

[0102] In one embodiment, when an indicator field is used to indicate multiple BWP indexes, different bit values ​​of the indicator field indicate indexes of different BWP sets.

[0103] The BWP indication information here uses one or more indication fields. An indication field can be one or more digits.

[0104] For example, an indicator field is used to indicate a BWP index. For instance, if the BWP indicator information uses three indicator fields, these three fields are the first indicator field, the second indicator field, and the third indicator field. When all bits of the first indicator field are "1", it indicates BWP0; when all bits of the first indicator field are "0", it does not indicate the BWP index of any BWP. When all bits of the second indicator field are "1", it indicates BWP1; when all bits of the second indicator field are "0", it does not indicate the BWP index of any BWP. When all bits of the third indicator field are "1", it indicates BWP2; when all bits of the third indicator field are "0", it does not indicate the BWP index of any BWP.

[0105] For example, one indicator field can be used to indicate multiple BWP indices. For instance, if the BWP indication information uses three indicator fields, these three fields are the first indicator field, the second indicator field, and the third indicator field. When all bits of the first indicator field are "1", it indicates BWP0 and BWP1; when all bits of the first indicator field are "0", it does not indicate the BWP index of any set of BWPs. When all bits of the second indicator field are "1", it indicates BWP2 and BWP3; when all bits of the second indicator field are "0", it does not indicate the BWP index of any set of BWPs. When all bits of the third indicator field are "1", it indicates BWP4, BWP5, and BWP6; when all bits of the third indicator field are "0", it does not indicate the BWP index of any set of BWPs.

[0106] In the example above, when an indicator field indicates multiple BWP indices, different bit values ​​can be used to indicate the BWP indices of different BWPs. For example, if the first indicator field is 32 bits, then: when bits 1 to 16 of the first indicator field are "1" and bits 17 to 32 are "0", it indicates BWP0; when bits 1 to 16 of the first indicator field are "0" and bits 17 to 32 are "1", it indicates BWP1; when all bits of the first indicator field are "0", it does not indicate the BWP index of a BWP.

[0107] In the example above, when an indicator field indicates multiple BWP indices, different bit values ​​can indicate the indices of different BWP sets. For example, when bits 1 to 16 of the first indicator field are "1" and bits 17 to 32 are "0", it indicates the BWP index of the set of BWP0 and BWP1; when bits 1 to 16 of the first indicator field are "0" and bits 17 to 32 are "1", it indicates the BWP index of the set of BWP2 and BWP3; when all bits of the first indicator field are "0", it does not indicate the BWP index of any BWP.

[0108] In one embodiment, when an indicator field indicates multiple BWP indexes, it can indicate BWP indexes of multiple consecutive BWPs or BWP indexes of multiple non-consecutive BWPs.

[0109] In the embodiments of this disclosure, one indicator field can be used to indicate one BWP index, achieving independent indication of the BWP index; alternatively, one indicator field can be used to indicate multiple BWP indices, achieving joint indication of the BWP indices. Thus, when an independent indication of a BWP index is achieved through an indicator field, a one-to-one correspondence between the indicator field and the BWP index can be established, making the indication more accurate and clear. Alternatively, when a joint indication of BWP indices is achieved through an indicator field, multiple BWP indices can be indicated through one indicator field, thereby saving bit overhead and thus reducing the signaling overhead and storage resource overhead for network devices and UEs in transmitting indication information.

[0110] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

Similarly, when a network device pages a UE, the BWP indication information can also be sent via DCI, further reducing signaling overhead.
