Description

Scheduling request transmission method and device, and resource allocation method and device

Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a scheduling request transmission method, a scheduling request transmission apparatus, a resource allocation method, a resource allocation apparatus, an electronic device, and a computer readable storage medium.

Background technique

When the user equipment needs to transmit new data in the uplink, the BSR (Buffer Status Report) is triggered. When no uplink resource is available for transmitting the BSR, the SR (Scheduling Request) can be triggered and passed through the PUCCH. (Physical Uplink Control CHannel) The resource transmits the SR to the base station to request uplink resources.

The user equipment also transmits data to the base station through the PUSCH (Physical UpLink Shared CHannel) resource, and the user equipment is in the current serving cell for a period of time, which is generally called a measurement interval, to monitor other cells. Frequency.

In the related art, when the PUCCH resource used for transmitting the SR and the PUSCH resource for transmitting data overlap with the measurement interval in the time domain, it will wait until the data is transmitted through the PUSCH resource, or wait until the measurement interval ends. The SR is transmitted through the PUCCH resource.

However, in some cases, the SR is triggered by a service with a shorter delay requirement. According to the method of transmitting the SR in the related art, the PUCCH resource transmission is performed after the data is transmitted through the PUSCH resource or after the measurement interval ends. The SR causes the time from the triggering of the SR to the transmission of the SR to be long, so that the delay of the service that triggers the SR cannot be met.

detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

FIG. 1 is a schematic flow chart of a scheduling request transmission method according to an embodiment of the present invention. The scheduling request transmission method shown in this embodiment can be applied to user equipment, such as a mobile phone, a tablet computer, or the like. The user may apply LTE communication or may apply NR communication.

As shown in FIG. 1, the scheduling request transmission method may include the following steps:

In step S1, it is determined whether the first time-frequency resource of the physical uplink control channel of the user equipment transmission scheduling request, and the second time-frequency resource of the uplink shared channel of the user equipment transmission data overlap in the time domain. Wherein, the time-frequency resource refers to a resource including a time domain and a frequency domain dimension, for example, the time domain dimension may be represented by a time domain symbol, and the frequency domain dimension may be represented by a frequency band.

In an embodiment, when the user equipment transmits data of the first service to the base station, the BSR may be triggered, and when no uplink resource is available for transmitting the BSR, the SR may be triggered, that is, the scheduling request. After the user equipment triggers the scheduling request, the scheduling request may be transmitted to the base station through the physical uplink control channel (PUCCH), but if the user equipment needs to transmit the data of the second service through the physical uplink shared channel (PUSCH), the physical uplink control channel is used. The second time-frequency resource that transmits the first time-frequency resource of the scheduling request and the data of the second uplink service of the physical uplink shared channel overlaps in the time domain.

The first time-frequency resource may be one, or may be multiple, preferably multiple, and periodically distributed in the time domain; the second time-frequency resource may be one, or may be multiple, preferably For one. The following is an exemplary description of the case where the first time-frequency resource is multiple, and the second time-frequency resource is multiple, and the first time-frequency resource is multiple, and the second time-frequency resource is one.

For example, when the first time-frequency resource is multiple and the second time-frequency resource is multiple, the first number of the plurality of first time-frequency resources in the preset duration after the current time may be used. Determining, by the user equipment, the first time-frequency resource of the physical uplink control channel of the scheduling request, and the user equipment, where the first time-frequency resource overlaps with the second second-time frequency resource of the second time-frequency resource The second time-frequency resource of the uplink shared channel transmitting the data has an overlap in the time domain.

The case where all the first time-frequency resources overlap with the plurality of second time-frequency resources may include a part of the first time-frequency resources of the plurality of first time-frequency resources being included in the time domain. The case of the second time-frequency resource may further include a case where a part of the first time-frequency resources of the plurality of first time-frequency resources partially overlap with one or some second time-frequency resources in the time domain.

For example, when the first time-frequency resource is multiple and the second time-frequency resource is one, the earliest first time-frequency among the plurality of first time-frequency resources within the preset duration after the current time may be used. When the resource overlaps with the second time-frequency resource, the first time-frequency resource of the physical uplink control channel for the user equipment to transmit the scheduling request is determined, and the second time-frequency resource of the uplink shared channel that transmits the data with the user equipment exists in the time domain. overlapping.

It should be noted that, in which manner, the first time-frequency resource of the physical uplink control channel of the user equipment transmission scheduling request is determined, and the second time-frequency resource of the uplink shared channel that is transmitted by the user equipment overlaps in the time domain. Can be set as needed.

In step S2, if there is overlap, the scheduling request is transmitted by the second time-frequency resource.

In an embodiment, when the first time-frequency resource of the physical uplink control channel of the user equipment transmission scheduling request is determined, and the second time-frequency resource of the uplink shared channel of the user equipment transmission data overlaps in the time domain, The scheduling request may be transmitted through the second time-frequency resource of the physical uplink shared channel, so that the scheduling request is used to request the uplink resource to transmit the buffer status report as soon as possible, so as to ensure that the requirement of the first service for the lower delay is met.

In an embodiment, the first configuration information may be transmitted by the base station to the user equipment to indicate that the user equipment transmits the scheduling request to the physical uplink control when the scheduling request is the scheduling request corresponding to the data of the first service. The first time-frequency resource of the channel, if the second time-frequency resource of the uplink shared channel of the user equipment transmission data overlaps in the time domain, the scheduling request is transmitted by using the second time-frequency resource, and the scheduling is performed. When the request is not a scheduling request corresponding to the data of the first service, the data of the second service is transmitted through the second time-frequency resource.

In an embodiment, the second configuration information may be transmitted by the base station to the user equipment to indicate that the user equipment transmits the first time-frequency resource of the physical uplink control channel of the scheduling request in the case that the preset function is enabled. If the second time-frequency resource of the uplink shared channel that is transmitted by the user equipment overlaps in the time domain, the scheduling request is transmitted by using the second time-frequency resource, and if the preset function is not enabled, The second time frequency resource transmits data of the second service.

The first time-frequency resource of the physical uplink control channel in which the user equipment transmits the scheduling request, and the second time-frequency resource of the uplink shared channel that the user equipment transmits data overlap in the time domain. In the case, the function of the scheduling request is transmitted through the second time-frequency resource.

2 is a schematic flow chart of transmitting the scheduling request by the second time-frequency resource according to an embodiment of the invention. As shown in FIG. 2, the scheduling request is a scheduling request triggered by data of the first service, and the data transmitted by the user equipment is data of the second service, where the method further includes:

In step S3, it is determined whether the priority of the data of the first service is higher than the priority of the data of the second service;

In one embodiment, the priority may be set in advance for the data of the service, for example, the priority of the data of the service may be set according to the delay required by the service. For example, the first service is a URL (Ultra Reliable & Low Latency Communication) service, which requires a lower latency, and the second service is an eMBB (Enhance Mobile Broadband) service. The delay is higher than the URLLC. Therefore, the data of the URLLC service can be set with a higher priority, and the data of the eMBB service can be set with a lower priority.

Therefore, in the case that the first time-frequency resource of the physical uplink control channel of the user equipment transmission scheduling request is determined, and the second time-frequency resource of the uplink shared channel of the user equipment transmission data overlaps in the time domain, the method may further Determining whether the priority of the data of the first service is higher than the priority of the data of the second service, and in the case that the priority of the data of the first service is higher than the priority of the data of the second service, The frequency resource transmits the scheduling request to send a buffer status report to the uplink resource as soon as possible by the scheduling request, so as to ensure that the delay between the data received from the URLLC service and the data of the URLLC service is short, thereby satisfying the URLLC service. For shorter delay requirements.

A first time-frequency resource is selected to send a scheduling request to the base station.

For the scheduling request corresponding to the first time-frequency resource that does not overlap, the status of the scheduling request may be represented by a 1-bit information bit, for example, 1 indicates that the scheduling request is a trigger state, and 0 indicates that the scheduling request is an untriggered state (negative) And, for the scheduling request corresponding to the overlapped first time-frequency resource, in order for the base station to clarify the state of the scheduling request corresponding to each configuration information, the information bits composed of the multi-bit bits may be transmitted to the base station.

In an embodiment, the state of the scheduling request corresponding to the service of the configuration information may be represented by the same number of bits of the configuration information corresponding to the overlapped first time-frequency resource.

For example, the base station allocates four pieces of modulation information to the user equipment as an example. If the scheduling request of the service corresponding to the first configuration information and the second configuration information is a trigger state, the third configuration information and the fourth configuration information correspond to the service. The scheduling request is not triggered, then the information bit is 1100, and the number of bits X of the information bits is equal to the number M of configuration information corresponding to the overlapping first time-frequency resources.

It should be noted that the base station may pre-agreed with the user equipment the bit corresponding to the status of the scheduling request of the service corresponding to each configuration information in the information bit, and then the base station acquires the information bit from the resource unit of the second time-frequency resource. According to the value of each bit in the information bit, the status of the scheduling request corresponding to the service of each configuration information may be determined, and since the data of the various services received by the user equipment is also sent by the base station, the base station may determine the user. The device triggers the scheduling request based on the data of the service, and determines the priority of the data of the service corresponding to the scheduling request in the trigger state, and allocates the resource for the scheduling request with the highest priority of the data corresponding to the service in the triggering request. .

In an embodiment, the status of the scheduling request of the configuration information corresponding service may be represented by a bit of the number of bits of the configuration information corresponding to the number of pieces of configuration information corresponding to the overlapped first time-frequency resource.

For example, when only one scheduling request corresponding to the overlapped first time-frequency resource is a triggering request, the status of the scheduling request may be indicated by 1 and the status of other scheduling requests by 0; If there are multiple scheduling requests in the scheduling request corresponding to the one-time frequency resource, the scheduling request of the service with the highest priority may be selected from one of the multiple scheduling requests, for example, the scheduling request corresponding to the data of the service with the highest priority, and 1 indicates the state of the selected scheduling request, and 0 indicates the state of the other scheduling request.

For example, the base station allocates four modulation information to the user equipment. Based on the representation of the information bits, there are only five cases, namely, 1000, 0100, 0010, 0001, and 0000, where 0000 refers to all scheduling requests. It is an untriggered state, and 1000 means that the scheduling request corresponding to the first configuration information is triggered, or the scheduling request corresponding to the first configuration information is triggered, and the data priority of the service corresponding to one configuration information is the highest. The meanings of 0100, 0010, and 0001 are similar to those of 1000, and are not described herein again.

Therefore, the state of the scheduling request in the above case can be represented by information bits capable of indicating five cases, that is, three bits, that is, in this case, the number of bits X of the information bits corresponds to the overlapped first time-frequency resource. The number of configuration information M is:

That is, X is equal to the upward rounding of the logarithm of M+1 with a base of 2. Based on this, with respect to the above-described case of X=M, the number of bits of information bits is small, facilitating operations such as code modulation and transmission.

In step S222, the information bits are code modulated to obtain modulation symbols to be transmitted.

In an embodiment, the information bits of the X bits can be code modulated to obtain Y bits and the number of resource units that need to be replaced. For example, the coding efficiency of the coded modulation mode is 1/4, X=1, and the modulation mode is QPSK. (Quadrature Phase Shift Keyin), the spectral efficiency is 1/2, then the Y bit can be obtained and corresponds to 2 resource units.

In step S223, the modulation symbol of the uplink data on one or more resource units in the second time-frequency resource is replaced with the modulation symbol to be transmitted.

In an embodiment, according to the modulation symbols to be transmitted and the number of resource units that need to be replaced, a corresponding number of resource units may be selected in the second time-frequency resource, and the modulation symbols of the uplink data are knocked out, and The modulation symbol to be transmitted is placed in the resource unit.

The base station can agree with the user equipment in which resource units to transmit the modulation symbols to be transmitted, and after receiving the content transmitted by the user equipment in the second time-frequency resource, the base station can obtain the to-be-transmitted from the corresponding resource unit. The modulation symbol is obtained, and the bit information corresponding to the scheduling request is obtained according to the decoding and demodulation method corresponding to the user equipment coded modulation mode, and accordingly, how to allocate resources for the user is determined.

Optionally, the code modulation mode is a preset code modulation mode.

In an embodiment, the base station may pre-agreed the code modulation mode and the corresponding demodulation and decoding mode with the user equipment, and then the user equipment encodes and modulates the information bits corresponding to the scheduling request according to the code modulation mode, and the base station obtains the code modulation. After the modulation symbol, the modulation symbol can be demodulated and decoded by using a corresponding demodulation decoding method to obtain bit information corresponding to the scheduling request, and accordingly, how to allocate resources for the user is determined.

In an embodiment, the user equipment may also select a coded modulation mode according to requirements, where the frequency domain bandwidth of the physical uplink shared channel and the first coded modulation mode for the uplink data may be determined first (the first coded modulation mode may be adopted) The uplink data is code modulated to obtain a modulation symbol of the uplink data, and one or more parameters of the number of time domain symbols occupied by the resource unit to be replaced in the second time-frequency resource, wherein the second adjustment code is determined Before the mode, the number of resource units to be replaced may be pending, but the number of time domain symbols occupied by the resource elements to be replaced may be determined (the relevant determining manner is explained in the following embodiments).

Since the spectral efficiency of the coded modulation mode is negatively correlated with the frequency domain bandwidth L of the physical uplink shared channel (the frequency domain bandwidth L is positively correlated with the number N1 of resource elements included in the frequency domain of the second time-frequency resource), and the first coded modulation The spectral efficiency E of the mode is positively correlated, negatively correlated with the number K of the time domain symbols, and in the case where the base station configures parameters, and is related to parameters such as a proportional coefficient a and a maximum number of resource units N2 that are allowed to be replaced, and further The second adjustment coding mode may be determined according to one or more of the parameters L, E, K, a, and N2.

Wherein, the number N3 of resource units that need to be replaced may be determined first. For example, considering the physical L, a, and N2,

Considering the physical L, E, a, and N2,

Considering the physical L, K, a, and N2,

After calculating the number N3 of resource units that need to be replaced, the code modulation mode capable of encoding and modulating the X-bit information bits to obtain the number of resource elements replaced by N3 may be determined according to the number of bits X of the information bits, for example, N3. = 2, then the QPSK modulation scheme with a coding efficiency of 1/4 can be selected as the second code modulation scheme.

In an embodiment, the modulation symbol of the uplink data in the resource unit uniformly distributed in the second time-frequency resource is replaced by the modulation symbol to be transmitted, so that the modulation symbol to be transmitted is also uniform in the second time-frequency resource. Distribution is beneficial to improve the diversity gain.

In an embodiment, the overlapping of the first time-frequency resource and the second time-frequency resource in the time domain may be summarized into three cases: first, the first time-domain symbol corresponding to the first time-frequency resource is included in the second time. a second time domain symbol corresponding to the frequency resource; second, the second time domain symbol corresponding to the second time-frequency resource is included in the first time domain symbol corresponding to the first time-frequency resource; and third, the first time-frequency resource corresponds to The first time domain symbol partially overlaps with the second time domain symbol corresponding to the second time-frequency resource, and the overlapping time domain symbol is the third time domain symbol.

For the first case, the modulation symbol of the uplink data on the one or more resource units in the resource unit corresponding to the first time domain symbol in the second time-frequency resource may be replaced with the modulation symbol to be transmitted; In either case, the modulation symbol of the uplink data on the one or more resource units in the resource unit corresponding to the second time domain symbol in the second time-frequency resource may be replaced with the modulation symbol to be transmitted; In a case, the modulation symbol of the uplink data on the one or more resource units in the resource unit corresponding to the third time domain symbol in the second time-frequency resource may be replaced with the modulation symbol to be transmitted.

According to this, the modulation symbol to be transmitted corresponding to the scheduling request can be guaranteed, and the corresponding symbol in the time domain is after the time when the scheduling request is triggered, so that the user equipment can have time to process the scheduling request, and the scheduling request can be avoided. The modulation symbol to be transmitted does not delay the corresponding symbol in the time domain, thereby reducing the delay of the service corresponding to the scheduling request.

In an embodiment, the first time-frequency resource in the second time-frequency resource and the uplink data on the one or more resource elements on the earliest time-domain symbol that coincide in the time domain of the second time-frequency resource may be The modulation symbol is replaced with the modulation symbol to be transmitted. According to this, not only the modulation symbol to be transmitted corresponding to the scheduling request can be guaranteed, but the corresponding symbol in the time domain is after the time when the scheduling request is triggered, so that the user equipment can have time. The scheduling request is processed, and the delay of the service corresponding to the scheduling request can be reduced as much as possible.

In one embodiment, one or more resource units may be uniformly set on the time domain symbols in the second time-frequency resource and the time-frequency symbols in the time domain of the second time-frequency resource, according to which, not only The modulation symbol to be transmitted corresponding to the scheduling request is guaranteed, and the corresponding symbol in the time domain is after the time when the scheduling request is triggered, so that the user equipment can have time to process the scheduling request, and the diversity gain can be improved as much as possible.

In an embodiment, since some time-frequency resources are used to transmit some special content, if the modulation symbols of the uplink data in the time-frequency resources are replaced, communication between the base station and the user equipment may be caused, for example, The modulation symbol of the reference signal in the time-frequency resource of the transmission reference signal is replaced, which may cause the base station to fail to perform channel estimation according to the reference signal, resulting in demodulation failure. Therefore, it is possible to set at least not to replace the modulation symbols of the reference signals in the time-frequency resources of the transmission reference signal to ensure good communication effects between the user equipment and the base station.

In an embodiment, if the first time-frequency resource and the second time-frequency resource overlap in the time domain, the time-frequency resource includes only the time-frequency resource used for transmitting the reference signal, if in the time-frequency resource of the transmission reference signal The replacement of the modulation symbol of the reference signal may cause a problem in communication between the base station and the user equipment. Therefore, the first time-frequency resource for transmitting the time domain symbol of the uplink data after the coincident time-frequency resource may be selected for uplink. The replacement of the modulation symbols of the data minimizes the delay of the service corresponding to the scheduling request on the premise of ensuring good communication effects between the user equipment and the base station.
