Density Signature (LDS) system, etc., of course, the SCMA system and the LDS system may also be referred to as other names in the communication field; further, the technical solution of the embodiment of the present application can be applied to multi-carrier using non-orthogonal multiple access technology. Transmission system, for example, Orthogonal Frequency Division Multiplexing (OFDM), Filter Bank Multi-Carrier (FBMC), General Frequency Division Multiplexing (Generalized Frequency Division Multiplexing (OFDM)) Frequency Division Multiplexing (GFDM), Filtered Orthogonal Frequency Division Multiplexing (Filtered-OFDM, F-OFDM) system, and the like.

The terminal device in the embodiment of the present application may refer to a user equipment (User Equipment, UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, and a wireless device. Communication device, user agent or user device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), with wireless communication. Functional handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in future 5G networks, or in the future evolution of the Public Land Mobile Network (PLMN) The terminal device and the like are not limited in the embodiment of the present application.

The network device in the embodiment of the present application may be a device for communicating with a terminal device, where the network device may be a Base Transceiver Station (BTS) in GSM or CDMA, or may be a base station (NodeB, NB) in a WCDMA system. ), can also be played in the LTE system The evolved NodeB (eNB or eNodeB) may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay station, an access point, an in-vehicle device, or The embodiment of the present application is not limited to a wearable device, a network device in a future 5G network, or a network device in a future evolved PLMN network.

FIG. 1 is a schematic diagram of an application scenario of an embodiment of the present application. The communication system in FIG. 1 may include a terminal device 10 and a network device 20. The network device 20 is configured to provide communication services for the terminal device 10 and access the core network. The terminal device 10 accesses the network by searching for synchronization signals, broadcast signals, and the like transmitted by the network device 20, thereby performing communication with the network. The arrows shown in FIG. 1 may represent uplink/downlink transmissions by a cellular link between the terminal device 10 and the network device 20.

If the UE does not have uplink data to transmit, the eNodeB does not need to allocate uplink resources for the UE, otherwise it will cause waste of resources. Therefore, the UE needs to tell the eNodeB whether it has uplink data to transmit, so that the eNodeB decides whether to allocate uplink resources to the UE. To this end, LTE provides a mechanism for an uplink scheduling request (Scheduling Request, SR). Generally, an SR is a 1-bit message transmitted on a Physical Uplink Control Channel (PUCCH).

In LTE, a media access control (MAC) entity corresponding to one terminal may configure one or more SR configuration. The SR configuration includes information such as the location and period of the PUCCH resource used to transmit the SR.

In the NR discussion, it has also been agreed to configure a plurality of SR configurations for a UE MAC entity, which also includes the Numerology used to transmit data.

At the same time, in NR, the system bandwidth supported by the terminal is much larger than the maximum 20 MHz system bandwidth supported by the terminal in LTE. For some terminals, due to limited capabilities, it is not always possible to support the full system bandwidth. In order to improve scheduling efficiency, the concept of BWP is introduced in NR, and BWP is a concept of frequency domain dimension. Different BWPs may differ in at least one of the following parameters: a base parameter set, a center frequency point, and a bandwidth. In the RRC connected state, the network can configure one or more BWPs for the terminal. At one point in time, the terminal can only support one active BWP. The so-called activation of a BWP means that the terminal can receive signals in a frequency band specified by a certain BWP, including data transmission, system messages, and the like.

Since the frequency bands of different BWPs may be different, the configuration parameters used for sending the SRs by different BWPs, for example, the PUCCH resources used for sending the SRs may be different. Therefore, how the terminal device sends the appropriate SRs on an activated BWP needs to be solved. problem.

FIG. 2 shows a schematic block diagram of a method 100 for transmitting data in an embodiment of the present application. As shown in Figure 2, the method includes some or all of the following:

S110. The terminal device determines a first logical channel for transmitting data.

S120. If the first BWP in the multiple bandwidth part BWP configured for the terminal device is in an active state, the terminal device sends a scheduling request to the network device according to the first logical channel and the first BWP.

Specifically, when the terminal device needs to send uplink data at a certain moment, the terminal device can determine which BWP is currently activated, and the terminal device can select which logical channel to use to transmit data, and the terminal device can be activated according to the current The BWP and the logical channel selected by the terminal device send a scheduling request to the network device. For example, a plurality of BWPs configured for the terminal device may be respectively configured with a mapping table, which may be a correspondence between a logical channel for transmitting data and configuration information for transmitting the SR. The terminal device can directly find the mapping table corresponding to the BWP according to the selected logical channel when determining which BWP is activated. Further, the terminal device can know which configurations are used to transmit the SR on the BWP.

Therefore, in the method for transmitting data in the embodiment of the present application, the terminal device sends a scheduling request to the network device in combination with the currently combined BWP, which is beneficial to improving the accuracy of sending the SR by the terminal device, thereby improving scheduling efficiency.

Optionally, the terminal device may also send a scheduling request to the network device in the currently activated BWP. For example, the currently activated BWP is the middle 40 MHz of the system bandwidth, and the PUCCH under the BWP can be transmitted on the third symbol of each time slot. When the terminal device selects the first logical channel, the terminal device can decide at the time. The SR is transmitted on the resource on the domain for the third symbol in each slot and in the frequency domain for the two subcarriers in the middle of the BWP.

Optionally, the terminal device may also send a scheduling request to the network device according to only the first BWP. That is to say, the terminal device can refer to the logical channel and directly refer to the BWP to send a scheduling request to the network device. For example, different scheduling request configuration information may be separately configured for different BWPs in advance. Once the terminal device determines which BWP is currently activated, the terminal device may determine corresponding scheduling request configuration information according to the BWP, and further, the terminal device adopts the determined The scheduling request configuration information sends a scheduling request to the network device. It should be understood that it is not necessary to configure different scheduling request configuration information for different BWPs in advance, and the terminal device only needs to select one resource transmission scheduling request on the symbols occupied by the PUCCH in the current BWP.

Optionally, in the embodiment of the present application, the multiple bandwidth part BWP in the terminal device When the first BWP is in an active state, the terminal device sends a scheduling request to the network device according to the first logical channel and the first BWP, including: when the first BWP is in an active state, the terminal device Determining first scheduling request configuration information corresponding to the first logical channel and the first BWP; the terminal device sends a scheduling request to the network device according to the first scheduling request configuration information.

Those skilled in the art understand that the purpose of mapping the logical channel with the SR configuration is to enable the network device to know the logical channel that triggers the SR transmission, and thus to know the required Numerology. For example, given SR configuration 1 (Numerology1), SR configuration 2 (Numerology2), assuming that the terminal has two logical channels, one logical channel a requires Numerology1 for data transmission, and one logical channel b requires Numerology2 for data transmission. Logical channel a can be mapped to SR configuration 1 and logical channel b can be mapped to SR configuration 2. Thus, if the network receives the SR of the data SR configuration 1, it knows that the logical channel a is triggered, and then sends the upstream grant of Numerology1.

Specifically, the network device may map the BWP, the logical channel, and the scheduling request configuration information in advance. For example, the network device configures the BWP-A and the BWP-B bandwidth for the terminal device, and the network device configures the terminal device with two bandwidths. SR configuration1 and SRconfiguration2, assuming that the terminal device has 3 logical channels for transmitting data, the network device can be configured with a mapping table as shown in Table 1:

Table 1

The network device may pre-arrange the PUCCH resource, the PUCCH period, or some other parameters related to the transmission SR corresponding to different SR configurations in different BWPs, and the terminal device may pre-store the mapping table between the logical channel and the SR configuration. Once the terminal device selects the logical channel, it can look up the mapping table to determine the SR configuration corresponding to the selected logical channel, and the terminal device can then send the SR of the currently activated BWP to the network device. Wherein, PUCCH-BWP-1-A and PUCCH-BWP-1-B may have the same PUCCH period. However, it does not limit the frequency domain location; or it may be the same frequency domain location, but has different PUCCH periods, or the two are completely different.

The mapping table of the network device configuration can also be as shown in Table 2. The network device directly considers the BWP when configuring all the parameters in the SR configuration for a certain logical channel, and the parameters in the SR configuration of each logical channel are targeted. Sexually, the same parameter values for different BWP configurations may be different.

	BWP-ABWP-A	BWP-BBWP-B
逻辑信道1Logical channel 1	SR configuration1-ASR configuration1-A	SR configuration1-BSR configuration1-B
逻辑信道2Logical channel 2	SR configuration2-ASR configuration2-A	SR configuration2-BSR configuration2-B
逻辑信道3Logical channel 3	SR configuration2-ASR configuration2-A	SR configuration2-BSR configuration2-B

Optionally, in the embodiment of the present application, in the case that the first BWP is in an active state, the terminal device determines the first scheduling request configuration information corresponding to the first logical channel and the first BWP, including: Determining, by the terminal device, the first scheduling request configuration information according to the first logical channel and a mapping relationship table corresponding to the first BWP, where the mapping relationship table includes a correspondence between at least one logical channel and at least one scheduling request configuration information, where The at least one logical channel includes the first logical channel.

After the terminal device determines which one of the currently activated BWPs, the terminal device may directly determine a mapping table corresponding to the currently activated BWP, for example, assuming that the currently activated BWP is BWP-A, the mapping table may include the following in Table 2. In the first column and the second column, after acquiring the mapping relationship between the first column and the second column, the terminal device can directly search for the corresponding scheduling request configuration information according to the selected logical channel. If the terminal device selects the logical channel 1, the terminal device may determine that the scheduling request configuration information is SR configuration1-A, and the terminal device may send a scheduling request to the network device according to various parameters included in the SR configuration1-A.

Optionally, in the embodiment of the present application, the first scheduling request configuration information includes location information of a physical uplink control channel PUCCH resource used for transmitting a scheduling request in the first BWP, and the terminal device is configured according to the first scheduling request. The configuration information is sent to the network device, and the terminal device sends a scheduling request to the network device on the PUCCH resource in the first BWP.

The above mentioned SR configuration includes at least a frequency domain location and/or a PUCCH period of a PUCCH for transmitting an SR, as long as the parameters related to the transmission of the SR can be in the SR configuration. Inside. After the terminal device determines a scheduling request configuration information, the terminal device sends a scheduling request to the network device by using the parameters included in the scheduling request configuration information. For example, the terminal device determines that a certain BWP is activated, and the terminal device can be based on the mapping relationship between the logical channel and the SR configuration. When a logical channel triggers the SR report, the mapped SR configuration can be used to select the PUCCH resource to be sent on the corresponding BWP. SR.

Optionally, in the embodiment of the present application, the logical channel and the SR configuration in the mapping relationship table pre-configured by the network device may be one-to-one correspondence, or multiple logical channels may be mapped to one SR configuration. The example is not limited to this.

When the network device configures multiple BWPs for the terminal device, the network device may switch the terminal device to switch between multiple BWPs by sending an instruction to the terminal device, that is, deactivate the current one BWP and activate another BWP.

Optionally, in the embodiment of the present application, the method further includes: the terminal device receiving the indication information sent by the network device, where the indication information is used to indicate that the working BWP of the terminal device is from the second BWP of the multiple BWPs Switch to the first BWP.

Such indication manners may include RRC signaling, Downlink Control Information (DCI), or MAC signaling. Alternatively, the terminal device can also be configured with a timer, that is, it can be switched between different BWPs according to a certain time rule. When the network device indicates the handover to the terminal device, that is, the information of the BWP to be activated may be notified, for example, it may be an identifier, or may be at least one of a central frequency point, bandwidth information, or a basic parameter set of the BWP to be activated.
