This application claims the priority of a Chinese patent application filed with the Intellectual Property Office of the People's Republic of China on September 30, 2021, with the application number 202111164810.7 and the application name "A Resource Allocation Method and Device", the entire contents of which are incorporated by reference In this application.

technical field

The embodiments of the present application relate to the field of communication technologies, and in particular, to a resource configuration method and device.

Background technique

The bandwidth capabilities of terminal devices in the new air interface (new radio, NR) of the fifth generation (5th generation, 5G) communication system are different. Some terminal devices can support the entire carrier bandwidth, which can be called ordinary terminal devices; some terminal devices can support bandwidth capabilities smaller than the carrier bandwidth, and can be called narrowband terminal devices. For example, the mobile communication standardization organization 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) proposes a reduced capability (reduced capability, RedCap) NR terminal device. One implementation of RedCap's terminal equipment is to reduce the channel bandwidth of the terminal equipment, which can also be understood as reducing the bandwidth capability of the terminal equipment. Rel-16 stipulates that the bandwidth capability of RedCap's NR terminal equipment in the frequency range 1 (frequency range 1, FR1) band is 20MHz, which is much lower than the 100MHz bandwidth capability of NR enhanced mobile broadband (eMBB) terminal equipment.

Take an eMBB terminal device with a bandwidth capability of 100 MHz as an ordinary terminal, and a RedCap terminal device with a bandwidth capability of 20 MHz as a narrowband terminal. As shown in Figure 1, the eMBB terminal device supports a bandwidth capability of 100MHz, and the RedCap terminal device supports a partial bandwidth of 20MHz. The network will configure uplink resources for terminal devices within the carrier bandwidth. Uplink resources include physical uplink control channel (physical uplink control channel, PUCCH) and physical uplink shared channel (physical uplink share channel, PUSCH). Other resources except PUCCH resources PUSCH can be allocated. PUCCH resources are generally configured at edge positions of a part of the bandwidth (bandwidth part, BWP) supported by the terminal device. The PUCCH resource of the common terminal equipment will be at the edge of the carrier bandwidth, as shown in the edge of the 100 MHz carrier bandwidth in FIG. 1 , as shown by the dotted shaded part. Since the bandwidth capability supported by the narrowband terminal equipment is smaller than the carrier bandwidth, the PUCCH resources of the narrowband terminal equipment may be distributed at non-edge positions of the carrier bandwidth, as shown in the white background part in FIG. 1 . This will cause the available PUSCH resources to be discontinuous, that is, the PUSCH resources are fragmented, and the PUSCH resources are shown in the oblique shaded part in FIG. 1 .

For a terminal device that does not support discontinuous resource allocation, it can only be allocated fragmented PUSCH resources, which will cause a serious drop in the uplink rate, especially the peak rate, of the terminal device.

Contents of the invention

Embodiments of the present application provide a resource configuration method and device for improving the uplink rate of common terminal equipment.

In the first aspect, a method for configuring resources is provided, and the execution subject of the method may be a terminal device, or may be a chip applied in the terminal device. The following description is made by taking the execution subject as a terminal device as an example. The method can be realized through the following steps: the terminal device receives the first random access message from the network device. Wherein, the first random access message includes configuration information of the first partial bandwidth BWP and the first physical uplink control channel PUCCH resource, and the first PUCCH resource is located in the first BWP. The first BWP is located within the carrier bandwidth, shifted from the boundary of the carrier bandwidth to the high frequency direction or to the low frequency direction by N resource blocks, where N is a non-negative integer; the terminal device uses the first PUCCH resource Send the PUCCH to the network device. Exemplarily, the first BWP may be a part of the carrier bandwidth, which may be located at the edge of the carrier bandwidth, for example, the edge of the first BWP may coincide with the edge of the carrier bandwidth, or be located near the edge of the carrier bandwidth, for example, the edge of the first BWP The edges may be spaced by N resource blocks from the edges of the carrier bandwidth. By designing the first BWP of the terminal equipment to be located at the edge of the carrier bandwidth, the continuously available PUSCH resources can be increased. Since there are more continuously available PUSCH resources, larger continuous PUSCH resources can be used for broadband terminal devices that do not support discontinuous resource allocation, thereby helping to ensure the uplink rate of these broadband terminal devices.

Exemplarily, the difference between the end position in the frequency domain of the first BWP and the start position in the frequency domain of the first BWP is the bandwidth occupied by the first BWP. The position offset by N resource blocks in the low frequency direction may refer to the position where the frequency domain starting position of the first BWP is offset by N resource blocks from the lower boundary of the carrier bandwidth to the high frequency direction, or the frequency domain of the first BWP The domain end position is a position offset by N resource blocks from the upper boundary of the carrier bandwidth to the low frequency direction.

For example, N=0, the frequency domain start position of the first BWP is aligned with the lower boundary of the carrier bandwidth, or the frequency domain end position of the first BWP is aligned with the upper boundary of the carrier bandwidth.

In a possible design, the first random access message is any one of the following messages: a conflict resolution message, a radio resource control RRC connection establishment message, an RRC connection re-establishment message or an RRC connection recovery message.

In a possible design, before the terminal device receives the first random access message from the network device, the terminal device sends the second random access message to the network device through the second BWP. For example, the second BWP can be configured in SIB1. The second random access message is sent by using the second BWP configured in SIB1, and the second BWP may not be limited to the edge of the carrier bandwidth, which can ensure flexible configuration of parameters required in the random access process.

In a possible design, no PUCCH resources are configured on the second BWP. Because the first PUCCH resource for transmitting the PUCCH is configured in the first BWP. In this manner, no PUCCH resources may be configured on the second BWP, that is, the purpose of reducing the configuration complexity of the second BWP can be achieved.

In a possible design, the second PUCCH resource is configured on the second BWP. In this manner, when the second BWP is configured through SIB1, the existing SIB1 signaling design may not be changed, thereby reducing design complexity and achieving the purpose of saving power consumption.

In a possible design, the terminal device performs resource switching based on a predefined method, and the resource switching includes: switching from the second BWP to the first BWP, and/or switching from the second PUCCH resource Switch to the first PUCCH resource. Through the pre-defined method of the protocol, there is no need to introduce additional configuration information to indicate switching, saving network resources.

In a possible design, the terminal device performs resource switching based on the indication information, and the resource switching includes: switching from the second BWP to the first BWP, and/or switching from the second PUCCH resource is the first PUCCH resource. It can explicitly indicate the switching action of BWP and PUCCH resources.

In a possible design, when the terminal device uses the first PUCCH resource to send the PUCCH to the network device, it may be implemented in the following manner: after receiving the first random access message, the terminal device After the first duration (for example, the first duration is not less than 10 milliseconds), use the first PUCCH resource to send the PUCCH to the network device, and the first duration is based on the terminal device processing the first random The time to access the message is determined. By introducing the first duration, it can be ensured that the signaling analysis of the first message can be completed, thereby increasing the robustness of the network.

In the second aspect, a method for resource configuration is provided, and the execution subject of the method may be a network device, or may be a chip applied in the network device. The following description is made by taking the execution subject as an example of a network device. The method may be implemented through the following steps: the network device sends a first random access message to the terminal device. Wherein, the first random access message includes a first partial bandwidth BWP and configuration information of a first physical uplink control channel PUCCH resource, and the first PUCCH resource is located in the first BWP. The first BWP is located within the carrier bandwidth, at a position offset by N resource blocks from the boundary of the carrier bandwidth toward a high frequency direction or toward a low frequency direction, where N is a non-negative integer. The network device receives the PUCCH from the terminal device by using the first PUCCH resource. Exemplarily, the first BWP may be a part of the carrier bandwidth, which may be located at the edge of the carrier bandwidth, for example, the edge of the first BWP may coincide with the edge of the carrier bandwidth, or be located near the edge of the carrier bandwidth, for example, the edge of the first BWP The edges may be spaced by N resource blocks from the edges of the carrier bandwidth. By designing the first BWP of the terminal equipment to be located at the edge of the carrier bandwidth, the continuously available PUSCH resources can be increased. Since there are more continuously available PUSCH resources, larger continuous PUSCH resources can be used for broadband terminal devices that do not support discontinuous resource allocation, thereby helping to ensure the uplink rate of these broadband terminal devices.

In a possible design, before the network device sends the first random access message to the terminal device, the network device receives the second random access message from the terminal device through the second BWP.

In a possible design, no PUCCH resources are configured on the second BWP.

In a possible design, the second PUCCH resource is configured on the second BWP.

In the embodiment of the present application, the involved terminal devices may include narrowband terminal devices and broadband terminal devices. Wherein, the narrowband terminal device may refer to a terminal device whose supported bandwidth is smaller than the carrier bandwidth, for example, a RedCap terminal device in NR or a terminal device in narrowband internet of things (NB-IoT). Broadband terminal devices can also be called ordinary terminal devices, which refer to terminal devices that support the bandwidth capability of the carrier bandwidth, for example, eMBB devices in NR, or ultra reliable low latency communication (URLLC) in NR equipment. It can be understood that the present application can also be applied in any of the following scenarios: the bandwidth supported by the broadband terminal device is greater than the bandwidth supported by the narrowband terminal device.

The RedCap terminal device is a reduced-capacity NR device, which is mainly used in scenarios such as industrial wireless sensing, video surveillance, or wearable devices. RedCap terminal equipment can have the following features: reduced equipment cost and complexity; low equipment size; the system supports frequency division duplex (frequency division duplex, FDD) and time division duplex (time division duplex, TDD) all FR1 and FR2 frequency bands .

Based on the problem of PUSCH resource fragmentation caused by resource configuration of narrowband terminals, the embodiment of the present application provides a method for resource configuration to solve the above problem.

Before introducing the resource configuration method provided by the embodiment of the present application, firstly, how to configure the PUCCH resource of the narrowband terminal device in Embodiment A. Hereinafter, the narrowband terminal equipment may be briefly referred to as terminal equipment. In Embodiment A, before the terminal device accesses the network, it will receive a synchronous broadcast signal block (SS/PBCH block, SSB) from the network device, and the SSB will carry some system information configuration information, and the system information can be, for example, a system message Block 1 (system information block 1, SIB1). The terminal device receives SIB1 according to the SSB. SIB1 includes the basic configuration parameters of the terminal equipment camping on and accessing the cell, and is used for uplink synchronization. For example, SIB1 includes initial uplink bandwidth part (bandwidth part, BWP), physical random access channel (physical random access channel, PRACH) resource, or physical uplink control channel (physical uplink control channel, PUCCH) resource. The terminal device performs random access according to the configuration parameters in SIB1, and after the random access, sends the PUCCH to the network device according to the configuration of the PUCCH resource in SIB1. Based on FIG. 1, it can be seen that since the operating bandwidth of the terminal is narrow and located at a non-edge position of the carrier bandwidth, the PUCCH resource configuration of the terminal device will cause the problem of PUSCH resource fragmentation.

Based on this, the embodiment of the present application provides a resource configuration method in order to solve the problem of PUSCH resource fragmentation. As shown in FIG. 3 , the flow of the resource configuration method provided by the embodiment of the present application is as follows. The method may be executed by the terminal device and the network device, or may also be executed by a chip in the terminal device and a chip in the network device. The network device in FIG. 3 may be the network device 120 in FIG. 2 above, and the terminal device may be the terminal device 110 in FIG. 2 above.

S301. The network device sends a first random access message to the terminal device, and correspondingly, the terminal device receives the first random access message from the network device.

Wherein, the first random access message includes configuration information of the first BWP and the first PUCCH resource, and the first PUCCH resource is located in the first BWP. The first BWP is located within the carrier bandwidth, and the first BWP is located at the edge of the carrier bandwidth, that is, the first BWP is located at a position offset by N resource blocks from the carrier bandwidth boundary to the high frequency direction or to the low frequency direction, and N is a non-negative integer, That is, N is 0 or N is an integer greater than 0.

It should be noted that the configured first BWP may be an initial uplink BWP or a dedicated uplink BWP.

S302. The terminal device uses the first PUCCH resource to send the PUCCH to the network device, and the network device uses the first PUCCH resource to receive the PUCCH from the terminal device.

Since some terminal devices are broadband terminal devices that do not support discontinuous resource allocation, by designing the first BWP of the terminal device to be located at the edge of the carrier bandwidth, the continuously available PUSCH resources are increased, thereby helping to ensure that discontinuous resource allocation is not supported The uplink rate of broadband terminal equipment.

Some optional implementation manners of the embodiment in FIG. 3 are described below.

Exemplarily, the first BWP is located at a position offset by N resource blocks from the carrier bandwidth boundary toward the high-frequency direction or toward the low-frequency direction. The difference between the end position in the frequency domain of the first BWP and the start position in the frequency domain of the first BWP is the bandwidth occupied by the first BWP.

For example, N is 0, and the frequency domain starting position of the first BWP is aligned with the lowest frequency domain position of the carrier bandwidth. For another example, N is 0, and the end position of the frequency domain of the first BWP is aligned with the highest frequency domain position of the carrier bandwidth.

For example, N greater than 0 means that the offset of the first BWP from the carrier bandwidth boundary is N resource blocks.

The frequency-domain start position of the first BWP may be located at a position where the lowest frequency-domain position of the carrier bandwidth is offset upward by the first offset value. Alternatively, the end position of the frequency domain of the first BWP is located at a position where the position of the highest frequency domain of the carrier bandwidth is shifted downward by the second offset value. The first offset value may refer to one or more frequency domain units, and the frequency domain units may be RBs or time units or other measurement units. Similarly, the second offset value may refer to one or more frequency domain units, and the frequency domain units may be RBs or time units or other measurement units.

The position of the first BWP is illustrated below with reference to the example in FIG. 1 . For example, the carrier bandwidth is 100MHz, and the first BWP is 20MHz. As shown in Fig. 4a, the first BWP is located at the lower edge of the carrier bandwidth, and the frequency domain starting position of the first BWP is aligned with the lowest frequency domain position of the carrier bandwidth. As shown in FIG. 4b, the first BWP is located at the upper edge of the carrier bandwidth, and the end position of the frequency domain of the first BWP is aligned with the highest frequency domain position of the carrier bandwidth. As shown in FIG. 4c, the first BWP is close to the lower edge of the carrier bandwidth, and the first BWP is located N resource blocks offset from the carrier bandwidth border to the high frequency direction, where N is greater than 0. As shown in FIG. 4d, the first BWP is close to the upper edge of the carrier bandwidth, and the first BWP is located N resource blocks offset from the carrier bandwidth boundary to the low frequency direction, where N is greater than 0. In Fig. 4c or Fig. 4d, on the N resource blocks of the first BWP offset, the PUCCH of the broadband terminal device may also be configured.

In Figures 4a to 4d, the PUSCH resources are shown by the shaded parts of the oblique lines. From Figures 4a to 4d, it can be seen that the continuously available range of PUSCH resources becomes larger, which is conducive to configuring larger continuous PUSCH resources for broadband terminal equipment. Guarantee the uplink rate of broadband terminal equipment.

As described in Embodiment A of resource configuration above, parameters such as initial uplink BWP, PRACH resource, and PUCCH resource of the terminal device can be configured in SIB1. In comparison, in the embodiment of FIG. 3 , the first BWP and the first PUCCH resource are configured in the first random access message. In this way, the uplink data transmission of the terminal device is based on the first BWP instead of the initial uplink BWP indicated in SIB1.

The first random access message is a message in the random access process. Exemplarily, the first random access message may be the last step message in the random access process. That is, during the random access process of the terminal device, the first random access message is the last message sent by the network device to the terminal device, and the terminal device completes the random access process after receiving the first random access message. The process of random access may be a four-step random access, including the following process: the terminal device sends a message 1 (carrying a random access preamble) to the network device, and the network device sends a message 2 (carrying a random access response) to the terminal device, The terminal device sends message 3 (bearer control information) to the network device, the control information includes the unique identifier of the terminal device, and the network device sends message 4 (bearer contention resolution information) to the terminal device. The first random access message may be Message 4. The process of random access may also be two-step random access, including the following process: the terminal device sends a message A (carrying a random access request) to the network device, and the network device sends a message B (carrying a random access response) to the terminal device, The first random access message may be Message B.

Optionally, the first random access message may be a conflict resolution message, a radio resource control (radio resource control, RRC) connection establishment message, an RRC connection re-establishment message, or an RRC connection recovery message.

The random access process may include multi-step messages, and the terminal device may also send a second random access message to the network device before receiving the first random access message from the network device. The terminal device may send the second random access message to the network device through the second BWP. For two-step random access, the second random access message may be message A, for example. For four-step random access, the second random access message may be message 1 or message 3.

The BWP used by the terminal device in the random access process and the BWP used for sending the PUCCH are configured separately. The first BWP is configured through the first random access message, and the second BWP needs to be configured before the random access, for example, the second BWP may be configured through SIB1.

Before the random access procedure, the network device sends SIB1 to the terminal device, and the terminal device receives the SIB1 from the network device. SIB1 includes configuration parameters related to uplink synchronization. For example, SIB1 may include initial uplink BWP (that is, second BWP) and PRACH resources, and may also include resources of message 3 . The PRACH resource and the resource of message 3 may be indicated based on the second BWP. After receiving the SIB1, the terminal device sends a preamble to the network device according to the PRACH resource indicated by the SIB1. The terminal device sends message 3 to the network device according to the resource of message 3 indicated by SIB1.

On the basis of configuring the first BWP and the first PUCCH resources in the first random access message, whether PUCCH resources need to be configured on the second BWP, two possible implementations are given below.

Manner 1: PUCCH resources are not configured on the second BWP.

For example, the configuration parameters of SIB1 do not include PUCCH resources, and the terminal device can perform random access according to SIB1, and after the first random access message indicates the first BWP and the first PUCCH resource, use the first PUCCH resource to send to the network device PUCCH. After connecting to the network, the terminal device has released the second BWP during data transmission with the network device, or the configuration of the second BWP is invalid. The terminal device can use the configuration of the first BWP, and because the configuration of the first BWP It is located at the edge of the carrier bandwidth, so it will not cause fragmentation of PUSCH resources.

On the basis of the first method, a schematic diagram of the first BWP and the second BWP received by the terminal device is shown in FIG. 5a. At time t1, the terminal device receives the configuration information of the second BWP from the network device, and no PUCCH resources are configured in the second BWP; at time t2, the terminal device receives the first random access message from the network device, and the first random access The message includes configuration information of the first BWP, and the first PUCCH resource is configured in the first BWP.

Manner 2: The second PUCCH resource is configured on the second BWP.

For example, when the second BWP is configured through the SIB1, the SIB1 also includes configuration information of the second PUCCH resource. In this case, the signaling of the existing SIB1 may not be changed. If it is desired that the terminal device transmits the PUCCH according to the first PUCCH resource in the first random access message, resource switching may be performed in the following manner. The resource switching includes switching from the second BWP to the first BWP, and also includes switching from the second PUCCH resource to the first PUCCH resource. After receiving the SIB1 message including the second PUCCH resource, the terminal device does not use the second PUCCH resource to transmit the PUCCH, but uses the first random access message in the first random access message after receiving the first random access message. The PUCCH resource transmits the PUCCH. The terminal device can perform resource switching based on a predefined method, that is, the protocol stipulates that the terminal device performs resource switching after receiving the first random access message. Alternatively, the terminal device performs resource switching based on the indication information, and the indication information may be carried in the first random access message. For example, the first random access message is message 4, which includes PDCCH and PDSCH, the configuration information of the first BWP and the first PUCCH resource is carried in the PDSCH of message 4, and the indication information is carried in the PDCCH of message 4 middle.

On the basis of the second method, a schematic diagram of the first BWP and the second BWP received by the terminal device is shown in FIG. 5b. At time t1, the terminal device receives configuration information of the second BWP from the network device, and the second BWP is configured with a second PUCCH resource; at time t2, the terminal device receives the first random access message from the network device, the first random access message The access message includes configuration information of the first BWP, and the first PUCCH resource is configured in the first BWP. After receiving the first random access message, the terminal device performs resource switching, and uses the first PUCCH resource to transmit the PUCCH.

Using the aforementioned mode 2, the terminal device needs a certain period of time to process the first random access message. Based on this, the terminal device may use the first PUCCH resource after receiving the first random access message after the first period of time Send the PUCCH to the network device. Wherein, the first duration is determined according to the time when the terminal device processes the first random access message. For example, the first random access message may carry RRC signaling. Generally, the duration for the terminal device to process the RRC signaling is not less than 10ms. The first duration may be set to be greater than or equal to 10ms, and an upper limit of the first duration may also be set. For example, The first duration is not greater than 20ms.

The following describes the resource configuration method in the embodiment of the present application in detail in combination with specific application scenarios.

Taking four-step random access as an example, as shown in FIG. 6 , the resource allocation method is as follows.

S601. The network device sends the SIB1 to the terminal device, and correspondingly, the terminal device receives the SIB1 from the network device.

Exemplarily, SIB1 includes an initial uplink BWP resource (corresponding to the second BWP above), and the initial uplink BWP resource is configured with parameters such as PRACH time-frequency resources and message 3 (Msg3 ) configuration information. In one manner, the initial uplink BWP is configured with second PUCCH resources, and in another manner, the initial uplink BWP is not configured with PUCCH resources.

S602. The terminal device sends a preamble, that is, message 1, to the network device by using the PRACH time-frequency resource according to the configuration parameters in SIB1. Correspondingly, the network device receives the preamble from the terminal device.

S603. The network device sends message 2 to the terminal device, that is, a random access response, and correspondingly, the terminal device receives the random access response from the network device.

S604. The terminal device sends the Msg3 to the network device based on the configuration information of the Msg3 in the SIB1, and the network device receives the Msg3 from the terminal device.

S605. The network device sends a message 4 to the terminal device. The message 4 is a conflict resolution message. Correspondingly, the terminal device receives the message 4 from the network device.

Message 4 includes configuration information of the first BWP and the first PUCCH resource, and message 4 corresponds to the first random access message above.

S606. The terminal device sends the PUCCH to the network device by using the first PUCCH resource. The network device receives the PUCCH from the terminal device by using the first PUCCH resource.

If the second PUCCH resource is configured on the initial uplink BWP in S601, the terminal device needs to perform resource switching, that is, switch from the second PUCCH resource to the first PUCCH resource, and switch from the second BWP to the first BWP.
