Description

Resource configuration determining and indicating method and device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a method and an apparatus for determining and indicating resource configuration.

Background

With the development of wireless communication technology and the increasing demand of users for communication, fifth Generation mobile communication (5G, 5th Generation) technology has become a trend of future network development in order to meet higher, faster and more recent communication needs.

In a Sidelink (Direct link) communication system, when there is a service to be transmitted between User Equipments (UEs), the service data between the UEs does not pass through the network side, i.e. not through the forwarding of the cellular link between the UE and the base station, but directly transmitted by the data source UE to the target UE through Sidelink, fig. 1 is a schematic diagram of a sildelink communication structure in the related art, as shown in fig. 1, this mode of direct communication between the UE and the UE has characteristics that are clearly distinguished from the conventional cellular system communication mode, for short-range communication users that can apply the sillink communication, the sillink communication not only saves wireless spectrum resources, and the data transmission pressure of the core network is reduced, the system resource occupation can be reduced, the frequency spectrum efficiency of the cellular communication system is increased, the terminal transmitting power consumption is reduced, and the network operation cost is saved to a great extent.

In a 5G communication system, the minimum granularity of a time domain resource is a symbol (symbol), which can be classified as: cyclic Prefix Orthogonal Frequency division multiplexing (CP-OFDM), or OFDM symbols based on Discrete fourier transform (DFT-S-OFDM).

Further, one slot (slot) includes: 12 long cyclic prefixes (extended CP) or 14 normal cyclic prefixes (normal CP), and fig. 2 is a schematic diagram showing a slot in a 5G system in the related art. As shown in fig. 2. Alternatively, a mini-slot may be formed of one or more consecutive symbols (less than or equal to 7 symbols). In the frequency domain, the minimum granularity of the resource is sub-carrier (sub-carrier), and each sub-carrier contains different frequency domain widths according to different system configurations, including any one or more of the following: 15kHz, 30kHz, 60kHz, 120kHz and 240 kHz. One frequency domain Resource Block (RB) may be constructed of 12 consecutive subcarriers. As described above, a symbol, a slot, or a mini-slot is a resource unit of time domain resource allocation in a 5G system, an RB is a resource unit of frequency domain resource allocation, and when implementing the Sidelink communication in the 5G communication system, the configuration of the Sidelink resource should also be implemented based on the same time domain and frequency domain resource units.

In a 5G system, the base station may indicate the time and frequency domain resource configuration for cellular communication for the cellular link UE. The method comprises the steps of dividing symbols and slots in a time domain and the type of each symbol; the division of subcarriers and RBs is included in the frequency domain. In the time domain, there are three symbol types: downlink symbols (DL symbol), uplink symbols (UL symbol), and flexible symbols (Fsymbol). Each symbol in each slot may be configured as any of the three symbol types described above. Fig. 3 is a diagram illustrating an example of a symbol type configuration in a slot in a 5G system in the related art. As an example shown in fig. 3, example #1 includes 5 DL symbols (shown as cross-hatched squares in fig. 3), 5 UL symbols (shown as cross-hatched squares in fig. 3), and 4 flex symbols (shown as blank squares in fig. 3). Wherein, DL symbol is used to carry downlink signals, i.e. signals sent from the base station to the UE; the UL symbol is used to carry uplink signals, i.e., signals sent by the UE to the base station; a flexile symbol is a flexibly reconfigurable symbol, that is, F symbol can be further reconfigured to DL symbol or UL symbol. In addition, symbols that have been configured as DL symbol or UL symbol cannot change symbol type. The symbol type and location in each slot is indicated by the system through signaling configuration. Other examples of symbol configurations in the Slot are shown in fig. 3 and are not described here.

When implementing the Sidelink communication in the 5G communication system, the Sidelink and the cellular communication share the resource, and simultaneously, the resource configuration of the Sidelink and the cellular communication is guaranteed not to conflict. Because a flexible resource configuration scheme and a scheduling indication mode are adopted in 5G cellular communication, no scheme is available at present to solve the problem of how to implement coordination configuration of cellular communication resources and Sidelink communication resources in a 5G system, and the disclosure provides a solution to the problem.

Detailed Description

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In the Sidelink communication system, the information is transmitted between UEs using the Sidelink resource, and the Sidelink communication method includes, but is not limited to: device to Device (D2D, Device to Device) communication, Vehicle to Vehicle (V2V, Vehicle to Vehicle) communication, and so forth. In the related art Sidelink communication, a UE transmits a Sidelink signal using a resource in a Sidelink resource pool (Sidelink resource pool). Wherein, the side link resource pool includes:

a Physical Sidelink Control Channel (PSCCH) resource pool for carrying Sidelink Control information; a Physical Sidelink Shared Channel (PSSCH) resource pool for carrying Sidelink data service information; a physical side link Broadcast Channel (PSBCH) resource pool, configured to carry sildenk Broadcast information; a Physical Sidelink Discovery Channel (PSDCH) resource pool for carrying a Sidelink Discovery signal; a Physical Sidelink Feedback Channel (PSFCH) resource pool for carrying Sidelink Feedback information.

The Sidelink resource pool may also be defined as a resource set including any one or more of the above Sidelink channel resources, for example, the Sidelink resource pool includes PSCCH, and PSFCH resources, and is not called PSCCH resource pool, or PSFCH resource pool. It should be noted that both ways are ways of defining the sildelink resource, and do not affect the essence of the present disclosure.

Generally, according to specific scenario requirements, a network side configures a Sidelink resource pool for a Sidelink UE, or a system configures the Sidelink resource pool in advance, and the UE uses resources in the Sidelink resource pool to carry the Sidelink information. In the network side configuration or the system predefined configuration, any one or more of the above-mentioned multiple types of sildelink resource pools may be configured for the sildelink UE. Where the system may be a wireless communications network system, which may be considered herein to be determined by higher level nodes, the Sidelink resource pool is a predefined configured set of resources.

When the UE performs Information interaction on the Sidelink, the sending end UE sends Sidelink Control Information (SCI) on PSCCH resources, and indicates, to the receiving end UE, PSCCH resources used by the transmitted Sidelink data Information, and related Control Information, such as Modulation and Coding Scheme (MCS), power Control indication, data retransmission indication, and the like. Further, the sending end UE sends the Sidelink data on the PSSCH resource indicated by the SCI. In addition, the UE may also send the Sidelink broadcast information on the PSBCH resource, send the Sidelink discovery information on the PSDCH resource, and feed back acknowledgement/non-acknowledgement information (Ack/Nack) of the received data packet to the transmitting end on the PSFCH resource.

The network side includes, but is not limited to, a base station (gNB), a relay station (RN), a cell coordination entity (MCE), a Gateway (GW), a Mobility Management Equipment (MME), an Evolved Universal Terrestrial Radio Access Network (EUTRAN) Operation Administration and Maintenance (OAM) manager, and the like.

Optionally, the Sidelink resource pool is a set of resources for carrying Sidelink information or signals, and is configured by the network side through physical layer and/or higher layer signaling, or is preconfigured by the system. Each sildelink resource pool may contain one or more time domain resource units in the time domain, where the time domain resource units include any one or more of the following: symbol, slot, mini-slot; one or more RBs are included in the frequency domain, and the included plurality of RBs may be continuous or discontinuous. The PSCCH resource pool, the PSSCH resource pool, the PSBCH resource pool and the PSDCH resource pool are all one of the Sidelink resource pools, and the configuration indication mode of the Sidelink resource pool in the application can be applied to any one or more resource pool configurations.

When the resources of the Sidelink resource pool share the cellular communication time domain and frequency domain resources, it needs to be configured based on the existing time domain and frequency domain resources in the cellular link. Such as: and further configuring time domain resources in the Silelink resource pool on the basis of the indicated symbols and slot division of the cellular link and the types of the symbols.

Since the UE can simultaneously maintain cellular communication and Sidelink communication, the configuration of the Sidelink resource pool needs to avoid conflict with the cellular communication resource as much as possible, that is, the time domain and frequency domain resources contained in the Sidelink resource pool should not affect the resource configuration of the cellular link as much as possible. In a new generation communication system, such as a 5G system, a UE performing cellular communication in a cell may determine a symbol type of each symbol in each slot in a time domain by receiving a corresponding configuration signaling of a network side node (e.g., a base station). Further, according to the scheduling indication of the base station, the UE receives or transmits signals using symbols of the corresponding symbol type.

It should be noted that, since the signal of the sildenk communication is transmitted by the UE and received by other surrounding UEs supporting the sildenk communication, in order to avoid interference from the cellular downlink signal, UL symbol and/or F symbol should be used in the pool of the sildenk resources, and DL symbol should be avoided. Here, the UL symbol or F symbol refers to UL symbol or F symbol allocated to a cellular link in cellular communication. When all symbols in a slot are configured as F symbols, they may also be referred to as F slots, and for simplicity, they are collectively referred to as F resources in the following description, where an F resource refers to a time domain symbol configured as F symbols, or an F slot. In addition, the F resource is a time domain resource indicated by the base station as F symbol or F slot in the resource configuration of cellular communication (i.e., on the Uu interface between the base station and the UE), and may be an F resource indicated by the base station through cell broadcast message configuration, or an F resource indicated in dedicated configuration information sent by the base station to the UE, where the dedicated configuration information includes a UE-specific RRC message or a DCI indication.

Since the F resource in the NR system can be further configured to indicate as DL resource or UL resource, there is a strong flexibility that the same slot or symbol can have different configurations for different UEs. For example, slot # n contains several fsymbols, which can be reconfigured as DL symbols for UE a and ul symbols for UE B. And when the F resource is configured as a DL resource, the F resource cannot be used as a Sidelink resource, and at this time, if the configuration is not properly coordinated, the configuration of cellular communication may conflict with the configuration of the Sidelink resource.

It should be noted that, multiple resource pools may be configured on the Sidelink at the same time, and the first configuration information and/or the second configuration information may be configured for each resource pool independently.

In addition, the UE may obtain the first configuration information and/or the second configuration information through pre-configuration.

The side link resource pool period indicates a repetition time of the side link resource pool configuration, for example, when the period is configured to 40ms, that is, the indicated time domain resource configuration in the Sidelink resource pool is repeated with the period of 40 ms.

Specifically, the Sidelink time domain resource configuration may indicate a slot index (slot index) in a period, where the indicated slot is a resource in the Sidelink resource pool. The slot index indicated is the sequential number of all slots contained in the Silelink resource pool period.

Or, the sildelink time domain resource configuration indicates a time slot in a period of the sildelink resource pool in a bitmap (bitmap) manner, the length of a bitmap sequence is less than or equal to a period value, each bit in the bitmap corresponds to one slot in the period, when a corresponding bitmap indication bit is "1", the slot is indicated as a resource in the sildelink resource pool, and when a corresponding bitmap indication bit is "0", the slot is indicated as not being a resource in the sildelink resource pool. When the second configuration information indicates the offset of the configuration of the Sidelink time domain resource in the period, the offset value starts to be shifted from the boundary of the period of the Sidelink resource pool, and the corresponding indication of the bitmap sequence starts.

Optionally, the offset is a system preconfigured value; the offset is the number of downlink time slots contained in the side link resource pool period; the offset is the sum of the number of downlink time slots and flexible time slots contained in the side link resource pool period; when the first configuration information indicates that the flexible resource is available for the sidelink, the offset is the number of downlink time slots contained in the sidelink resource pool period; when the first configuration information indicates that the flexible resource is not available for the side link, the offset is the sum of the number of downlink time slots and the number of flexible time slots included in the side link resource pool period.

Specifically, when the offset indicated in the second configuration information is the Sidelink resource pool period offset, the indicated offset is an offset of the start position of the Sidelink resource pool period with respect to the system Frame number sfn (systemframe number) or direct link Frame number dfn (direct Frame number) boundary.

When the offset indicated in the second configuration information is an offset of the Sidelink time domain resource configuration in the period, the indicated offset refers to a relative offset of the Sidelink time domain resource indication information indicated in the second configuration information, such as bitmap, with respect to a boundary of the Sidelink resource pool period.

The offset may be a preconfigured value or implicitly determined according to a predefined rule when the offset represents an offset of the Sidelink time domain resource configuration within a period, without explicit indication in the second configuration information, e.g. the offset value is equal to the number of DL slots in the Sidelink resource pool period, or the offset is equal to the sum of the number of DL slots and the number of F slots in the Sidelink resource pool period, or the offset value is determined according to the first configuration information, e.g. when the first configuration information indicates that F resources are not available, the offset is equal to the sum of the number of DL slots and the number of F slots in the Sidelink resource pool period, and when the first configuration information indicates that F resources are available, the offset is equal to the number of DL slots in the Sidelink resource pool period.

It should be noted that a plurality of sidelink resource pools may be configured on the same edge link resource, and the configuration indication of the sidelink resource pools is independent for each resource pool.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present disclosure may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present disclosure.

As shown in fig. 12, the UE receives a cell system broadcast message, and obtains first configuration information and second configuration information configured by the base station. The type1 first configuration information received by the UE indicates that the cell common F resource is unavailable for the Sidelink. In addition, the UE also receives a dedicated RRC message of the base station, indicating type2 first configuration information dedicated to the UE, wherein it is indicated that F resources indicated in the first node-specific configuration signaling are available for Sidelink.

As shown in the following drawing in fig. 12, after the base station is reconfigured by the RRC message, the slot #4, #5 is an F slot. And the priority rule defined by the system is that when the configuration indications of the first indication information of multiple types obtained by the UE on the same F resource are different, the indication of the first configuration information of type2 is taken as the standard, that is, the indication of the first configuration information of type1 is invalid, that is, the slot #4 and the F resource #5 are resources available for the sildelink to the UE.

In the second configuration information indicated in the broadcast message, the period of the Sidelink resource pool is indicated to be 10ms, and taking the length of each slot as 1ms as an example, the second configuration information indicates that the Sidelink resource pool includes slots #2, #3, #4, #5, #6, #7, # 8.

As shown in fig. 14, the second configuration information indicates that the period of the scellink resource pool is 10ms, and the symbol configurations for the scellink in each slot are the same, and are symbol #5 to # 11. Taking the length of each slot as 1ms as an example, the second configuration information indicates a bitmap sequence "0011111000" of 10 bits, which is used to indicate the Sidelink slots, and the indicated time domain resource configuration in the Sidelink resource pool.

Fig. 15 is another resource configuration diagram based on scenario five according to an embodiment of the present disclosure. As shown in fig. 15, another example is that the second configuration information indicates that the period of the Sidelink resource pool is 40ms, 10ms is used as a group, the configurations of the Sidelink symbols in slots in the same group are the same, and the period is divided into 4 groups. Taking the slot length of 1ms as an example, slots #1, #3, #5, #39 are sildelink slots, the sildelink symbols in the first group are configured as all symbols in the slot, the sildelink symbols in the second group are configured as #7 to #13 in the slot, the sildelink symbols in the third group are configured as #4 to #8 in the slot, the sildelink symbols in the fourth group are configured as #11 and #12 in the slot, and the time domain resource configuration in the sildelink resource pool indicated in the second configuration information is as shown in the figure.

Scene six

The system pre-configures the first configuration information and the second configuration information of the configuration of the common Silelink resource on the special carrier of the Silelink communication. The second configuration information indicates that the Sidelink resource pool includes all time domain resources, for example, when indicated by bitmap, the bitmap sequence is a full "1" sequence. In addition, the dedicated carrier has a preconfigured time domain resource class, for example, all time domain resources are UL resources, or are F and UL resources, and the positions of the F resource and the UL resource are preconfigured by the system.

And when the UE works on the dedicated carrier, determining the resources of the Silelink resource pool through the pre-configured first configuration information and second configuration information.

When the first configuration information indicates that the F resource is available, all the time domain resources on the dedicated carrier are resources in the Sidelink resource pool according to the indication of the second configuration information. When the first configuration information indicates that F resources are not available, the Sidelink resources include all UL resources.

Scene seven

The resource partitioning unit of the UE and the base station on the cellular communication link may not be the same as the resource partitioning unit used by the UE on the Sidelink, that is, the subcarrier spacing and the slot length of the cellular communication uplink are different from the subcarrier spacing and the slot length on the Sidelink. At this time, the indication of the time domain resource included in the Sidelink resource pool needs to be converted in the resource division unit of the two resources.

Scene ten

On the Sidelink dedicated carrier, the system pre-configures first configuration information, namely type0 first configuration information, to be available for F resources. Further, the UE obtains type1 first configuration information from the base station, indicating that F resources are unavailable. According to the usage rule of the first configuration information predefined by the system, when the UE has the type0 and type1 first configuration information at the same time, the configuration indication of the two is on the same F resource, taking the indication of the type1 first configuration information as a standard, and the indication of the corresponding type0 first configuration information is invalid at this time.
