Description

Channel configuration method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a channel configuration method and apparatus.

Background

Currently, 3GPP NR (New Radio) is mainly deployed to operate in licensed carriers. However, with the rapid growth of data traffic, the licensed bands will no longer be able to withstand such huge amounts of data in the near future. Therefore, NR needs to be deployed in the unlicensed frequency band, and data traffic in the licensed carrier needs to be shared by the unlicensed frequency band. However, frequency band resources are limited in both licensed and unlicensed frequency bands, and it is expected that even if NR can be deployed in an unlicensed frequency band, the licensed and unlicensed frequency bands still cannot satisfy the increasing data services.

Therefore, a new technical scheme is urgently needed to be provided to improve the utilization rate of frequency band resources.

Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

Referring to fig. 1a, fig. 1a is a flowchart illustrating a channel configuration method according to an embodiment of the disclosure.

The method may be applied to a terminal, which is also referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like, and is a device that provides voice and/or data connectivity to a user, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and the like. Currently, some examples of terminals are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), a wireless terminal in vehicle networking, and the like.

As shown in fig. 1a, the method comprises:

step S110, sending uplink control information UCI to the base station,

In a possible implementation manner, the method of the present disclosure may send channel resource information to a base station through UCI after a terminal accesses a channel of an unlicensed frequency band or a licensed frequency band, the method and the device realize that the base station and the terminal share the channel occupying time to configure the shared channel resource between the terminal and the base station, thereby improving the utilization rate of the channel resource. The terminal and the base station can communicate with each other by using the occupied shared channel resource.

In one possible implementation, the shared channel resources may include time domain resources and frequency domain resources.

In one possible embodiment, the channel resource information may be carried in a predetermined number of bits added to the UCI or carried in a predetermined number of bits originally in the UCI.

Referring to fig. 1b, fig. 1b is a flowchart illustrating a channel configuration method according to an embodiment of the disclosure.

As in fig. 1b, the method may further comprise:

step S120, adding a preset number of bits in the UCI, or using the original preset number of bits in the UCI to carry the channel resource information.

The channel resource information can be written into the UCI by adding a preset number of bits in the UCI or by using idle preset number of bits in the UCI, and when the terminal sends the UCI to the base station, the channel resource information can be carried by the UCI and sent to the base station by the terminal so as to configure the shared channel resources of the terminal and the base station.

In a possible implementation manner, when the values of the bits of the preset number of bits are all 1 (when the preset number is 7, the value is 255), or all 0, or other specified values, the channel resource information may be used to indicate not to share, and when the base station receives that the bits of the preset number of bits are all 1 (or all 0, or other specified values), it may be determined that no channel resource is shared.

In one possible implementation, the terminal may receive the number of slot intervals transmitted by the base station; and the interval between the initial time slot for carrying out shared channel resource configuration and the time slot for sending the UCI is the number of the time slot intervals. As shown in fig. 1b, the method may further include:

step S130, receiving the time slot interval number sent by the base station;

step S140, determining the time slot spaced from the time slot for transmitting the UCI by the time slot spacing number as the initial time slot for performing the shared channel resource allocation.

The terminal may receive the number of time slot intervals of the base station and determine the starting time slot of the shared channel resource according to the time slot intervals, for example, the time slot spaced from the time slot of the terminal for transmitting the UCI by the number of time slot intervals may be determined as the starting time slot of the shared channel resource.

In one possible embodiment, the number of time slot intervals may be any value, for example, 0,1,2, etc., and the disclosure is not limited to the specific value of the number of time slot intervals. For example, if the slot interval number is 0, the start slot is the next slot adjacent to the slot in which the UCI is transmitted.

The present disclosure can flexibly configure shared channel resources by the number of slot intervals.

It should be understood that the preset number may be determined according to different situations, for example, the preset number may be determined by the number of symbols in a timeslot, the number of types of timeslot formats configured by the radio resource control RRC, and the like, so as to improve the utilization rate of the preset number of bits as much as possible.

In a possible embodiment, the preset number may be

In one possible implementation, the number of symbols included in the slot may be 12, 14, etc., and the base station may indicate the number of symbols included in the slot through the cyclic prefix CP as needed. In one example, when the number of symbols in the slot is 12, the preset number is 7.

In a possible embodiment, when the value of each bit of the preset number of bits is 1 (when the preset number is 7, the value is 255), the channel resource information may be used to indicate not to share, and when the base station receives that each bit of the preset number of bits is 1, it may be determined that there is no shared channel resource.

In a possible implementation manner, when the value of each bit of the preset number of bits is not all 1, the channel resource information may be used to indicate sharing, when the base station receives that the preset number of bits is not all 1, it may be determined that the terminal has the shared channel resource to the base station, and the shared channel resource may be obtained according to the value of the preset number of bits, for example, the starting symbol and the number of consecutive symbols (i.e., the symbol length) of the starting timeslot. For example, a predetermined number of bits may be preset, and a portion of the bits represents a start symbol in the start slot and a portion of the bits represents a symbol length. Hereinafter, similarly, it is possible to previously set which part of a preset number of bits respectively represents which information.

In a possible implementation manner, when the value of each bit of the preset number of bits is not all 1, the channel resource information may be used to indicate sharing, and when the base station receives that the preset number of bits is not all 1, it may be determined that the terminal has a shared channel resource to the base station, and the shared channel resource may be obtained according to the value of the preset number of bits, for example, the shared channel resource may be the number of consecutive slots starting from the slot and an end symbol of a last slot in the consecutive slots. Of course, it can also be agreed that the shared channel resource can be the number of consecutive slots from the start of the slot, and the length of the symbol of the last slot in the consecutive slots as the shared channel resource.

In a possible embodiment, the preset number may be

For example, when the number of types of the radio resource control RRC configured slot formats is 4, the predetermined number is 2. The two bits may correspond to index information of 4 slot formats, for example, the index information may be in the form of uuuuuuffffffddddd, that is, symbol configuration information expressed as a type of each symbol in the starting slot, in this example, the symbol configuration information indicates that symbols in the starting slot, which are occupied shared channel resources, are symbols from symbol 9 to symbol 14 (that is, a D symbol), where U may represent an uplink symbol, F may represent a flexible symbol (which may be used as an uplink symbol or a downlink symbol), and D may represent a downlink symbol. It can be agreed that only downlink symbols can be used as the symbols of the shared channel resources occupied.

In one possible embodiment, the preset number may be

Wherein, N represents the number of the PDCCH monitoring time of the physical downlink control channel in the initial time slot, and the start-stop information represented by the channel resource information is the first symbol of the ith PDCCH monitoring time and the previous symbol of the (i + 1) th PDCCH monitoring time in the initial time slot, where i represents the value of the bit of the preset number, and i is less than N.

Referring to fig. 2a, fig. 2a is a schematic diagram illustrating a start timeslot according to an embodiment of the present disclosure.

As shown in fig. 2a, in the starting timeslot, the number of listening time points for the terminal to listen to the PUCCH includes 4, where the first listening time point is symbol 0-symbol 1, the second listening time point is symbol 4-symbol 5, the third listening time point is symbol 8-symbol 9, and the fourth listening time point is symbol 12-symbol 13. When the number of the monitoring time is 4, the preset number is 3, and the start-stop information indicated by the channel resource information may be a first symbol of an ith PDCCH monitoring time and a previous symbol of an (i + 1) th PDCCH monitoring time in the start time slot. For example, when the value of the preset number of bits is 3, the shared channel resource is symbol 8 (the first symbol of the 3 rd listening time instant) -symbol 11 (the previous symbol of the 4 th listening time instant) in the starting slot.

Of course, in other embodiments, the start-stop information indicated by the channel resource information may be the first symbol of the i-1 st PDCCH monitoring time and the previous symbol of the i-th PDCCH monitoring time in the starting slot. For example, when the value of the predetermined number of bits is 3, the shared channel resource is symbol 4-symbol 7 in the starting slot.

In a possible implementation, when the value of the preset number of bits is 0 (each bit is 0), the channel resource information may be used to indicate that the terminal does not share the channel resource to the base station. When the value of the preset number of bits is not 0 (any bit is not 0), the channel resource information may be used to indicate that the terminal has the shared channel resource to be shared by the base station.

In one possible embodimentIn (1), the preset number is

Starting and ending information represented by the channel resource information is a first symbol of a jth PDCCH monitoring moment and an ending symbol of a j + l-1 monitoring moment in the starting time slot, j and l are values carried by the preset number of bits, j<N，l＜N。

With reference to fig. 2a, when the number of the listening time instants is 4, the preset number may be 4, and thus 4 bits may be used to carry the channel resource information. For example, when j is 1 and l is 3 in channel resource information carried by a preset number of bits, the shared channel resource can be obtained as symbols 0 to 9 in the starting time slot according to that "the starting and stopping information indicated by the channel resource information is the first symbol of the jth PDCCH monitoring time and the ending symbol of the jth + l-1 monitoring time in the starting time slot".

The case where the shared channel resource is determined to be 1 slot (starting slot) was described above, however, the present disclosure is not limited thereto, and the terminal may use a plurality of consecutive slots from the starting slot as the shared channel resource, and the case where the shared channel resource includes a plurality of slots will be described below.

the number of the first parts is

K represents the number of continuous time slots of a Physical Uplink Shared Channel (PUSCH) from the starting time slot or the number of opportunities for repeated transmission by using the PUSCH, and the channel resource information carried by the value of the first part comprises the number of continuous time slots from the starting time slot;

In one possible implementation, the number of bits of the first portion may be determined according to the number of consecutive slots allowing transmission of the UCI.

Referring to fig. 2b, fig. 2b is a schematic diagram illustrating PUSCH resources of a terminal according to an embodiment of the present disclosure.

In a possible implementation manner, the base station may configure the slot resource of the PUSCH by means of a bitmap (bitmap), where the configured slot of the PUSCH is a resource allowing transmission of UCI (of course, traffic data may also be transmitted), for example, for 10 slots, slot 1 to slot 5 may be configured by means of the bitmap as consecutive slots of the PUSCH, where the configuration format of the bitmap may be "0111110000".

For example, as shown in fig. 2b, when UCI is transmitted in slot 2 and the slot interval is assumed to be 0, the number of consecutive slots of PUSCH is 3 (including slot 3-slot 5), and then the number of the first part is 2. Of course, in addition to calculating the number of the first part by using the number of consecutive slots of the slot resource of the PUSCH, the number of consecutive "1" in the configuration format of bitmap may also be used for calculation, that is, K may also be the number of consecutive 1 in the configuration format of bitmap.

In one possible implementation, when the value of the bit of the first part is set to 0, the channel resource information may indicate that channel resource sharing is not performed for the base station. When the value of the bits of the first portion is set to another value, the other value may be used to indicate the slot length of the shared channel resource. For example, when the value of the bit of the first part is 2, the channel resource information may indicate that 2 slots from the start slot may be used as the shared channel resource.

The base station can configure the resources of the terminal in a bitmap mode, and can also configure the PUSCH resources of the terminal in a configuration period and offset mode.

For example, please refer to fig. 2c, fig. 2c shows a schematic diagram of PUSCH resources of a terminal according to an embodiment of the present disclosure.

The base station may configure the number of opportunities for PUSCH repetition transmission in a certain period. When the subcarrier spacing is SCS =15kHz, the period is 10ms, the offset is 1ms, and the number of repetitions is 4, it may be configured to allow transmission on slot 1, slot 2, slot 3, slot 4 every 10 slots. The transmitted content may be UCI, or may be service data.

When UCI is transmitted in slot 2 and it is assumed that the slot interval is 0, it may be determined that the number of opportunities for PUSCH repeated transmission from the start slot is 2, including slot 3 and slot 4, and at this time, the number of the first parts may be found to be 2.

In one possible implementation, when the value of the bit of the first part is set to 0, the channel resource information may indicate that channel resource sharing is not performed for the base station. When the value of the bits of the first portion is set to another value, the other value may be used to indicate the slot length of the shared channel resource. For example, when the value of the bit of the first part is 2, the channel resource information may indicate that 2 slots from the start slot may be the shared channel resource.

After the number of the consecutive slots of the shared channel resource is carried by the bits of the first portion, the bits of the second portion may be used to carry symbol information of a symbol used as the occupied shared channel resource in the last slot of the consecutive slots. Thus, the occupied shared channel resources are all symbols of the time slots except the last time slot in the continuous time slots from the initial time slot, and the symbols indicated by the symbol information of the last time slot.

For example, if the value of the first part indicates that the number of consecutive slots is 2, and the starting slot is slot 3, the slots available for sharing are slot 3 and slot 4, and the second part indicates that symbols 1 to 4 in slot 4 are available for sharing, the shared resources occupied are all symbols of slot 3 and symbols 1 to 4 in slot 4.

In one possible embodiment, the shared channel resource in the last slot of the consecutive slots may be set by using the above-described various ways of setting the shared channel resource of the starting slot.

For example, the number of the second part may be determined by the number of slots, and channel resource information is carried according to the value of the bits of the second part, where the channel resource information includes a starting symbol and the number of consecutive symbols in the last slot of the consecutive slots; the number of the second part can be determined by the type number of the time slot format configured by the radio resource control RRC, the value of the bit of the second part corresponds to the index information of the time slot format, the channel resource information carried by the index information comprises the symbol configuration information of the last time slot in the continuous time slots, and the symbol configuration information indicates the symbol which is taken as the occupied shared channel resource in the last time slot in the continuous time slots; the number of the second part can also be determined by the number of the PDCCH monitoring time of the physical downlink control channel in the last time slot of the consecutive time slots, where the start-stop information represented by the channel resource information carried by the bit value of the second part is the first symbol of the ith PDCCH monitoring time and the previous symbol of the (i + 1) th PDCCH monitoring time in the last time slot of the consecutive time slots, where i represents the value of the preset number of bits, or the start-stop information represented by the channel resource information carried by the bit value of the second part is the first symbol of the jth PDCCH monitoring time and the end symbol of the (j + l-1) th monitoring time in the last time slot of the consecutive time slots.

Of course, the number of the second portions and the specific introduction of the corresponding channel resource information refer to the previous description of the channel resource information of the initial timeslot, which is not described herein again.

It should be understood that the above description of a preset number is exemplary and should not be taken as limiting the present disclosure. The specific value of the preset number may be determined in other ways selected by those skilled in the art when faced with other situations.

Through the method, the present disclosure may send the channel resource information to the base station through a preset number of bits in the UCI, so as to configure the shared channel resource between the base station and the terminal.

Referring to fig. 3, fig. 3 is a flowchart illustrating a channel configuration method according to an embodiment of the disclosure.

The method may be applied to base stations, and examples of some base stations are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc.

The method comprises the following steps:

step S210, acquiring channel resource information for shared channel resource allocation according to the received uplink control information UCI;

step S220, performing resource allocation of a shared channel by using the channel resource information, where the channel resource information represents start-stop information of a shared channel resource occupied by communication between the terminal and the base station.

By the method, after receiving the uplink control information UCI sent by the terminal, the base station can acquire the channel resource information for carrying out the shared channel resource allocation from the UCI and carry out the shared channel resource allocation by using the channel resource information. The method and the device can utilize the shared channel resource shared by the terminals to carry out downlink data transmission, thereby saving the channel resource. The shared channel resources between the terminal and the base station are configured by using the start-stop information of the shared channel resources, so that the communication efficiency and accuracy between the terminal and the base station can be improved.

In one possible embodiment, the channel resource information includes:

the configuring of the shared channel resource by using the channel resource information may include:

For example, the channel resource information includes that the starting timeslot is timeslot 3, the starting symbol in the starting timeslot is symbol 1, and the number of consecutive symbols is 3, then the occupied shared channel resources are symbol 1, symbol 2, and symbol 3 in timeslot 3.

For another example, the channel resource information includes that the starting timeslot is timeslot 3, the number of consecutive timeslots from the starting timeslot is 2, and the ending symbol in the last timeslot in the consecutive timeslots is symbol 3, so that the occupied shared channel resource is all symbols of timeslot 3, and symbol 0, symbol 1, symbol 2, and symbol 3 in timeslot 4.
