Description

Transmission resource determination method and device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for determining transmission resources, an electronic device, and a storage medium.

Background

When a signal such as a synchronization signal is transmitted by using a beam, if a carrier frequency of 6GHz or less is used, a maximum of 8 beams can be transmitted, and a continuous downlink time of 2 milliseconds needs to be occupied. However, in actual communication, the communication system cannot actually transmit 8 beams, so that the coverage of signals transmitted by the 8 beams is smaller than expected, and the communication quality is poor.

However, in the scale experiment, since a small uplink and downlink switching period (such as 2ms or 2.5 ms) is adopted, the frame structure cannot provide continuous two-ms downlink time, so that an actual system cannot transmit 8 beams, and the coverage of the synchronization signal is lower than that expected by the standard.

Detailed Description

The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.

Research shows that the uplink and downlink periods of the frame structure have the following characteristics: 2 milliseconds (ms) and 2.5 ms. If a frame adopts a special subframe ratio of 10: 2: the uplink and downlink period of 2, 2ms can send 5 SS/PBCH blocks at most, the uplink and downlink period of 2.5ms can send 7 SS/PBCH blocks at most; there are less than 8 SS/PBCH blocks.

If a special subframe ratio adopted by one uplink and downlink period is as follows: 12: 2: 0; sending 6 SS/PBCH blocks at most in the uplink and downlink period of 2 ms; there are less than 8 SS/PBCH blocks.

The subframe ratio is as follows: the number of downlink subframes in one uplink and downlink period is: number of Guard Period (GP) subframes: the ratio between the number of uplink subframes. For example, the ratio of 10: 2: 2, if the special subframe ratio is taken as an example, the frame structure includes: including 10 downlink subframes, 2 guard interval subframes, and 2 uplink subframes.

One of the uplink and downlink periods is: one transmission cycle of signal transmission.

The uplink and downlink periods of the special subframe ratio include Guard Period (GP), on one hand, due to the introduction of GP, the configuration flexibility of the frame is limited, and on the other hand, the Guard Period of 4 transmission symbols cannot be met, so that a reference signal (SRS) or a random access control channel (PRCH) cannot be transmitted on the special subframe.

If far-end base station interference needs to be considered in the later stage of 5G deployment, a relatively long GP needs to be set aside in the system in the hall to avoid uplink and downlink cross slot interference, for example, 12 symbols are set aside in a 2ms period (corresponding to a special subframe ratio of 6: 6: 2, where there are 6 symbols with subcarrier bandwidth of 15 kHz), or 18 symbols are set aside in a 2.5ms period (corresponding to a special subframe ratio of 3: 9: 2, where there are 9 symbols with subcarrier bandwidth of 15 kHz), as shown in fig. 3. Wherein, the 2ms period can only send 4 SS blocks, and the 2.5ms period can only send 5 SS blocks, which can not reach the maximum number supported by the standard.

If a worse GP is introduced, less resources are available for SS/PBCH blocks within one frame.

In the embodiment of the present invention, in order to implement transmission of an SS on each beam in a cell in a half frame, implement overall coverage of the SS in the entire cell, and/or facilitate flexible configuration of a GP on each subframe, in the embodiment of the present invention, a resource location of a candidate SS/PBCH block is determined according to at least one of a subcarrier interval, a carrier frequency, and an uplink and downlink period. For example, a resource location of a candidate SS/PBCH block is determined by determining an index determination of a first symbol of the candidate SS/PBCH block. Fig. 5 is a schematic diagram illustrating that the entire cell is covered by 8 SS blocks (SS blocks, SSBs); SSB 0-SSB 7 are shown in FIG. 5. Fig. 6 is a schematic diagram illustrating resource locations of 8 SSBs in a 2ms, 2.5ms uplink and downlink period. Comparing fig. 6 and fig. 7, if the number of symbols occupied by GP in fig. 7 is increased, the positions of the candidate SSBs may be occupied by GP is increased, and the number of SSBs actually used for transmitting the synchronization signal is decreased. After 8 SSBs are sent in two uplink and downlink periods, the flexibility of GP configuration can be increased and the overall coverage of synchronization signals can be ensured. Fig. 8 and 9 show schematic diagrams of sending 8 SS blocks in two uplink and downlink periods.

As shown in fig. 1, the present embodiment provides a method for determining transmission resources of a signal, including:

step S100: for a field containing a SS/PBCH block, the index of the first symbol in the candidate SS/PBCH block is: indexes { N1, …, Nm } + L × N, N ═ N1, N2, … nk; n1, n2, … nk comprises: discrete natural numbers, or fractions of n1, n2, … nk. The method can be applied to a receiving end, and the receiving end can determine the index of the first symbol of the candidate SS/PBCH block according to the functional relation. The receiving end may comprise a terminal. The terminal may include various User Equipment (UE), for example, a mobile phone, a tablet computer, a wearable device, an in-vehicle device, or an internet of things terminal.

The terminal may be connected to an access network element, which is a network element located in an access network. The access network element is various network elements located in an access network, and includes: evolved base stations, next generation base stations, radio remote units or relay nodes, etc. In summary, the access network element may be a network element providing a connection of the terminal to the network.

The access network element may transmit a beam on which a synchronization signal or a PBCH signal may be transmitted on a candidate SS/PBCH block. The synchronization signal may be used for synchronization between the terminal and the access network element, and the synchronization signal may include: a primary synchronization signal and/or a secondary synchronization signal. The PBCH block may carry various signals transmitted by PBCH; for example, a Master System Information (MSI) transmitted by PBCH, etc.

In some embodiments, the SS block is: a resource block for transmitting a synchronization signal; the PBCH block is a resource block for sending PBCH signals. The candidate SS blocks may be: candidate resource blocks for the SS block. The candidate PBCH block may be: candidate resource blocks for the PBCH block.

One of the resource blocks may include: a plurality of symbols. These symbols are distributed continuously in the video domain, for example, one of the SS block and the PBCH block may include: n symbols, for example, N may be 4, and optionally, the N symbols are consecutive time-frequency resources, for example, frequency-domain resources of N symbols belonging to the same SS/PBCH block are the same, and time-domain resources are consecutive. The symbol may be a basic unit of a kind of time-frequency resource used for communication. The symbols may include: orthogonal Frequency Division Multiplexing (OFDM).

In some embodiments, the candidate PBCH block and the candidate SS block may correspond to the same resource block. For example, different time-frequency resources of the same resource block are used to transmit the synchronization signal or the PBCH signal, respectively. For example, one resource block contains multiple (e.g., 4) symbols, wherein part (e.g., 2) of the symbols may be used for transmitting the synchronization signal, and part (e.g., 2) of the resources may be set to PBCH for the PBCH to transmit its required information. Thus, one resource block is realized to transmit the synchronization signal and the PBCH signal simultaneously, and the resource block may be referred to as an SS block or a PBCH block, which may be referred to as an SS/PBCH block in this embodiment. Of course, the above is merely an example, and in a specific implementation, one of the PBCH blocks may be configured as a dedicated resource block of PBCH, and not configured with a resource for transmitting a synchronization signal; one of the SS blocks may also be configured as a dedicated resource block for transmitting a synchronization signal without the configuration of PBCH. The SS/PBCH block may be used for resource blocks in which SS and PBCH signals are transmitted.

In some embodiments, the terminal may not currently know which beam sent by the access network element can be received, but knows candidate SS/PBCH blocks of each beam in advance, and the terminal may monitor on the candidate SS/PBCH blocks, and if the candidate SS/PBCH block of the currently monitored beam carries a synchronization signal or a PBCH signal, the terminal completes monitoring of the SS/PBCH block and receives the synchronization signal or the PBCH signal sent by the access network element.

The L may be a length of one resource unit; n may be a resource number of a resource unit. For example, if the resource unit is a timeslot, n may be a timeslot number of the timeslot, and if the resource unit is a minislot, n may be an index of the minislot. If the value of n is a decimal number, for example, 2.5 represents the 2.5 th resource unit, indicating the resource at the middle position of the 2 nd resource unit.

In some embodiments, the Nm value is less than the L. The minimum value of N1 may be 0.

In some embodiments, a slot may include a plurality of symbols, e.g., a slot includes: 14 symbols, 7 symbols, or 28 symbols, etc. Taking an example that a time slot includes 14 transmission symbols, according to a communication standard, at least two symbols need to be reserved before and after the time slot and are respectively configured as a downlink control channel and an uplink control channel, so that at least 4 symbols are reserved in the time slot of one 14 symbol and are used for configuring the uplink control channel and the downlink control channel; thus, only 10 symbols remain for transmission of the synchronization signal or the PBCH signal in a 14-symbol slot. If one SS/PBCH block contains 4 symbols, then 8 SS blocks or 8 PBCH blocks are transmitted, requiring at least two slots.

The first symbol may be: the first symbol contained in the candidate SS/PBCH block is described.

Thus, in order to satisfy compatibility with existing communications, it is necessary to complete transmission of 8 SS/PBCH blocks within a certain time duration (e.g., 5ms), i.e., the terminal needs to detect 8 SS/PBCH blocks from different slots. The duration of 1 frame may be 1m and 5ms may be half a frame. The time conversion relationship among the frame, the subframe and the time slot can be as follows: 1 frame-10 sub-frames-20 slots. If the slot contains 14 symbols, then 1 frame is 140 symbols.

In this embodiment, on one hand, the transmission of 8 SS/PBCH blocks needs to be completed within a half frame, and meanwhile, a subframe needs to be reserved and set as a GP, so as to facilitate flexible setting of the GP. In this embodiment, the SS/PBCH block is set on multiple discontinuous timeslots, so the terminal needs to listen to the SS/PBCH block on multiple discontinuous timeslots. On one hand, resources reserved between discontinuous time slots can be used for flexibly setting GP, on the other hand, transmission of SS/PBCH blocks of preset times in a half frame can be completed by repeatedly transmitting the SS/PBCH blocks on a plurality of discontinuous time slots, so that full coverage of synchronous signals or PBCH signals is realized, the problem that a terminal cannot synchronize or cannot successfully receive MSI and other information transmitted by PBCH due to full coverage is solved, and communication quality is improved.

The information interaction between the access network element and the terminal is according to a transmission period, which may be referred to as an uplink and downlink period in this embodiment. The uplink and downlink periods can be divided into: an uplink and downlink period of 2.5ms, and an uplink and downlink period of 2 ms. If the uplink and downlink period is 2.5ms, it means that there is a transition of uplink and downlink transmission within the duration of 2.5 ms. If the uplink and downlink period is 2ms, it means that there is a transition of uplink and downlink transmission within the duration of 2 ms.

In this embodiment, before monitoring the SS/PBCH block, the terminal determines a candidate SS/PBCH block according to at least one of the duration of the uplink and downlink periods, the subcarrier interval of the current beam, and the carrier frequency. After determining the candidate SS/PBCH block, monitoring a synchronization signal or monitoring a PBCH on the candidate SS/PBCH block.

In some embodiments, if one resource unit includes 14 symbols, then indexes { N1, …, Nm } + L × N may be: indexes {2, 8} +14 × n. Further, at this time, n is 0, 1, 4, 5; or, n is 0, 1, 5, 6; but is not limited to these values.

If the number of symbols included in a resource unit is 28, then indexes { N1, …, Nm } + L × N may be: {4,8, 16, 20}+28*. Further, at this time, n is 0, 2; alternatively, N is 0, 2.5.

For example, if the subcarrier spacing is 30kHz, the index of the first symbol of the candidate SS/PBCH block is: indexes {2, 8} +14 × n.

The indexes { N1, …, Nm } represents an initial value of an index of a first symbol of a candidate SS/PBCH block; n denotes a resource number of a resource unit such as a slot number of a slot in which the symbol is located. Usually, a sub-frame or frame comprises a plurality of time slots which are numbered sequentially from the front to the back; for example, the slot number starts from 0.

In some embodiments, the value of n may be determined according to the duration of the current uplink and downlink period, where the value of n may be a value of a timeslot. A communication system may support both 2.5ms and 2ms uplink and downlink periods, but only one uplink and downlink period may be used at a time, and the duration of the uplink and downlink period may be modified if necessary.

For example, the currently used uplink and downlink period of 2.5ms, considering requirements of various aspects, may modify the uplink and downlink period of 2.5ms into the uplink and downlink period of 2ms, and during the modification of the uplink and downlink period, the access network element and the terminal may negotiate through information interaction. For example, if the uplink and downlink periods are:

if the subcarrier spacing is 30kHz and the uplink and downlink period is 2ms, the index of the first symbol of the candidate SS/PBCH block is: indexes {2, 8} +14 × n; for example, if the carrier frequency of the candidate SS/PBCH block is greater than 3GHz and less than or equal to 6GHz, n may be equal to 0, 1, 4, or 5.

If the subcarrier spacing is 30kHz and the uplink and downlink period is 2.5ms, the index of the first symbol of the candidate synchronization signal block or the candidate PBCH block is: indexes {2, 8} +14 × n; if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n may be equal to 0, 1, 5, or 6.

In some embodiments, step S100 may include:

In this embodiment, L is 28, which corresponds to a resource unit including 28 resources; n is the resource number of the resource unit.

In some embodiments, n is 0, 2; alternatively, N is 0, 2.5.

For example, if the period is 2ms for uplink and downlink, the value of n may be 0 or 2. If the uplink and downlink period is 2.5ms, the value of n may be 0 or 2.5.

For another example, the carrier frequency of the SS/PBCH block is greater than 3GHz and less than or equal to 6 GHz; if the uplink and downlink period is 2ms, the value of n may be 0 or 2. If the uplink and downlink period is 2.5ms, the value of n may be 0 or 2.5.

As shown in fig. 2, the present embodiment provides a method for determining transmission resources, including:

step S200: for a half frame containing a synchronization signal SS/physical broadcast control channel PBCH block, the index of the first symbol in the candidate SS/PBCH block is: indexes { N1, …, Nm } + L × N, N ═ N1, N2, … nk; m x k is greater than L.

In some embodiments, L is the maximum number of candidate SS/PBCH blocks in each field.

The first symbol in the candidate SS/PBCH block is the first symbol in the candidate SS/PBCH block. The index of the first symbol may be determined according to the functional relationship, so that the terminal listens to signals transmitted by the SS or PBCH on the candidate SS/PBCH block determined according to the functional relationship.

In this embodiment, m × k is greater than the maximum number of candidate SS/PBCH blocks in each half frame, so that the candidate SS/PBCH blocks can be flexibly configured in the whole half frame.

In some embodiments, if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, L-8.

In other embodiments, if the carrier frequency is greater than 6GHz, L is 64.

In still other embodiments, if the carrier frequency is greater than or equal to 3GHz, L-4. The carrier frequency here is the frequency of the carrier of the candidate SS/PBCH block.

In some embodiments, the Nm is less than the L.

In still other embodiments, the step S200 may include:

In other embodiments, n is 0, 1, 4, 5, 6; or, n is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9;

alternatively, n is 0, 1.

For example, 30kHz spacing for subcarriers; if the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1; if the carrier frequency is greater than 3GHz and less than or equal to 6GHz for a subcarrier spacing of 30kHz, n is 0, 1, 4, 5, 6; or n is 0, 1, 2, 3, 4, 5, 6.

For another example, if the carrier frequency is greater than 3GHz and less than or equal to 6GHz and the uplink and downlink period is 2ms, n is 0, 1, 4, 5, 6. If the carrier frequency is greater than 3GHz and less than or equal to 6GHz and the uplink and downlink period is 2.5ms, n is 0, 1, 2, 3, 4, 5, 6

In some embodiments, the step S200 may include:

Further, n is 0, 1; or, n is 0, 1, 4, 6; or n is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

For example, the spacing is 30kHz for subcarriers and n may be equal to 0 or 1 if the carrier frequency is less than or equal to 3 GHz.

For another example, if the subcarrier spacing is 30kHz and the carrier frequency is greater than 3GHz and less than or equal to 6GHz, then n is 0, 1, 4, 6; or n is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. For example, if the uplink and downlink period is 2ms, n is 0, 1, 4 or 6; if the uplink and downlink period is 2.5ms, n is 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.

If the uplink and downlink period of the final fused frame structure is 2ms, the SS block is transmitted in the first ms and the third ms of the field, as shown in fig. 9, it can be seen that this configuration mode can support all types of special subframe allocations, including: GP of 12 symbols and the like greatly enhance deployment flexibility while ensuring SS block coverage.

For example, in a half frame, determining the index of the first symbol of a candidate SS/PBCH block according to subcarrier spacing may be determined in one of the following ways:

if the subcarrier spacing is 15kHz, the index of the first symbol is: indexes {2, 8} +14 × n.

If the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1, and if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 1, 2, or 3.

If the subcarrier spacing is 30kHz, the index of the first symbol is: indexes {4, 8, 16, 20} +28 × n. If the carrier frequency is less than or equal to 3GHz, n is equal to 0, and if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0 or 2.

If the subcarrier spacing is 30kHz, the index of the first symbol is: indexes {2, 8} +14 × n.

If the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1, and if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 1, 4, or 5.

By adopting the method to configure the SS/PBCH block, 8 SS/PBCH blocks can be sent in two periods, and only all special subframe ratios are matched.

Example 2:

if the uplink and downlink period of the final merged frame structure is 2.5ms, the SS block is transmitted in the first ms and 2.5-3.5 ms of the field, as shown in fig. 10. According to the method, all special subframe ratios and the GP of 26 symbols in the uplink and downlink period of the 2.5 millisecond single frame structure can be supported, and all special subframe ratios and the GP of 10 symbols in the uplink and downlink period of the 2.5 millisecond double frame structure can also be supported.

If the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1, and if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 2, or 5.

If the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1, and if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 1, 5, or 6.

Once the SS block is determined to be transmitted in the

time slots

4 and 5, the uplink and downlink period is actually determined to be 2ms, and if the terminal is implemented according to the determination, the uplink and downlink ratio cannot be modified to be 2.5ms at a later stage.

Once the SS block is determined to be transmitted in the

time slots

5 and 6, the uplink and downlink period is actually determined to be 2.5ms, and if the terminal is realized according to the determination, the uplink and downlink ratio cannot be modified to be 2ms any more in the later period.

Example 3:

one solution is to require the terminal to perform SS block monitoring in all of slot 4, slot 5 and slot 6, so that the SS block design can support both 2ms and 2.5ms periods, and the index of the first symbol of the SSB can be as follows:

for example, in a half frame, the index of the first symbol of the candidate SS/PBCH block determined according to the subcarrier spacing is determined based on the subcarrier spacing, and may be specifically determined in one of the following manners:

if the subcarrier spacing is 15kHz, the index of the first symbol of the candidate SS/PBCH block is: indexes {2, 8} +14 × n; if the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1; if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 1, 2, or 3.

If the subcarrier spacing is 30kHz, the index of the first symbol of the candidate SS/PBCH block is: indexes {4, 8, 16, 20} +28 × n; if the carrier frequency is less than or equal to 3GHz, n is equal to 0; if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 2, or 2.5.

If the subcarrier spacing is 30kHz, the index of the first symbol of the candidate SS/PBCH block is: indexes {4, 8, 16, 20} +28 × n; if the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1; if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 1, 4, or 6.

If monitoring the time slot 4, the time slot 5 and the time slot 6, after the terminal accesses the network to read the system information, the uplink and downlink periods can be obtained, and the position of the SS block irrelevant to the current uplink and downlink ratio does not need to be monitored subsequently.

Example 4:

a resource location of a candidate SS block is determined by taking all SS block locations within 5ms as SS blocks to be monitored (candidate SS block locations) as follows:

for example, in a half frame, the index of the first symbol of the candidate SS/PBCH block is determined according to the subcarrier spacing, which may be determined in one of the following manners:

the first condition is as follows: if the subcarrier spacing is 15kHz, the index of the first symbol is: indexes {2, 8} +14 × n.

The SSB determined in this manner can be as shown in fig. 11.

If the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1, if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 1, 2 or 3;

case two: if the subcarrier spacing is 30kHz, the index of the first symbol is: indexes {4, 8, 16, 20} +28 × n. If the carrier frequency is less than or equal to 3GHz, n is equal to 0, and if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 0.5, 1, 1.5, 2, 2.5, 4, or 4.5.

Case three: if the subcarrier spacing is 30kHz, the index of the first symbol is: indexes {2, 8} +14 × n.

If the carrier frequency is less than or equal to 3GHz, n is equal to 0 or 1, and if the carrier frequency is greater than 3GHz and less than or equal to 6GHz, n is equal to 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9.

According to the scheme (the terminal detects all SSB positions) the terminal complexity and power consumption can be increased to a certain extent, and the method for improving the terminal complexity and power consumption is that in the initial access stage, the terminal monitors all possible SSB positions, and after the terminal reads system information and learns the uplink and downlink proportion, the terminal can detect the SSB according to the related uplink and downlink proportion. A table of SSB detection locations associated with uplink and downlink assignments is as follows:
