Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It should be understood that the technical solutions of the embodiments of the present application may be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), an LTE System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a New Radio (NR), a future 5G System, or the like.

In particular, the technical solution of the embodiment of the present application may be applied to various communication systems based on a non-orthogonal Multiple Access technology, such as a Sparse Code Multiple Access (SCMA) system, a Low Density Signature (LDS) system, and the like, and certainly the SCMA system and the LDS system may also be called other names in the communication field; further, the technical solution of the embodiment of the present application may be applied to a Multi-Carrier transmission system using a non-Orthogonal multiple access technology, for example, an Orthogonal Frequency Division Multiplexing (OFDM) using a non-Orthogonal multiple access technology, a Filter Bank Multi-Carrier (FBMC), a General Frequency Division Multiplexing (GFDM), a Filtered Orthogonal Frequency Division Multiplexing (F-OFDM) system, and the like.

A terminal device in the embodiments of the present application may refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. 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), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, and the embodiments of the present application are not limited thereto.

The Network device in this embodiment 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, a Base Station (NodeB, NB) in a WCDMA system, an evolved node b (eNB or eNodeB) in an LTE system, a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network device in a future 5G Network, or a Network device in a future evolved PLMN Network, and the like, and the embodiment of the present application is not limited.

Fig. 1 is a schematic diagram of an application scenario according to 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 used to provide a communication service to the terminal device 10 and access a core network, and the terminal device 10 accesses the network by searching for a synchronization signal, a broadcast signal, or 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 over a cellular link between the terminal device 10 and the network device 20.

If the UE has no uplink data to transmit, the eNodeB does not need to allocate uplink resources for the UE, otherwise, resources are wasted. Therefore, the UE needs to tell the eNodeB whether there is uplink data to transmit itself, so that the eNodeB decides whether to allocate uplink resources to the UE. For this purpose, LTE provides a Scheduling Request (SR) mechanism. Generally, the 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 scheduling request configurations (SR configurations). SR configuration includes information such as the position and the cycle of a PUCCH resource for transmitting SR.

In the NR discussion, it has also been agreed to configure a UE MAC entity with multiple SR configurations that also include Numerology with which data is transmitted.

Meanwhile, in NR, a system bandwidth supported by a terminal is much larger than a maximum system bandwidth of 20MHz supported by the terminal in LTE. For some terminals, the full system bandwidth may not necessarily be supported due to limited capabilities. To improve scheduling efficiency, the concept of BWP, which is a concept of frequency domain dimension, is introduced in NR. Different BWPs may differ in at least one of the following parameters: basic parameter set, central frequency point and bandwidth. In the RRC connected state, the network may configure the terminal with one or more BWPs. At a time point, the terminal can only support one active BWP, that is, the terminal can receive signals including data transmission, system messages, etc. on a frequency band specified by a certain BWP.

Since the frequency bands of different BWPs may be different, the configuration parameters, e.g. PUCCH resources, used for transmitting SRs for different BWPs may be different, and therefore, how the terminal device transmits an appropriate SR on an active BWP is a problem to be solved.

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

s110, the terminal device determines a first logical channel for transmitting data.

S120, in case that a first BWP of the plurality of bandwidth portions BWPs 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 time, the terminal device may determine which BWP is currently activated, and the terminal device may select which logical channel to use to transmit data, and then the terminal device may send a scheduling request to the network device according to the currently activated BWP and the logical channel selected by the terminal device. For example, a mapping table may be configured in advance for each of the BWPs configured for the terminal device, where the mapping table may be a correspondence between a logical channel used for transmitting data and configuration information used for transmitting the SR. The terminal device may directly look up the mapping table corresponding to the BWP according to the selected logical channel when determining which BWP is active, and further, the terminal device may know which configuration to use to transmit the SR on the BWP.

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

Alternatively, the terminal device may also decide to send the scheduling request to the network device within the currently activated BWP. For example, the currently active BWP is the middle 40MHz of the system bandwidth, and assuming that the PUCCH in this BWP can be transmitted on the third symbol in each slot, when the terminal device selects the first logical channel, the terminal device may decide to transmit the SR on the resource which is the third symbol in each slot in the time domain and is the middle two subcarrier intervals within this BWP in the frequency domain.

Alternatively, the terminal device may send the scheduling request to the network device only according to the first BWP. That is, the terminal device may transmit the scheduling request to the network device with reference to the logical channel, directly with reference to the BWP. For example, different scheduling request configuration information may be configured for different BWPs in advance, and once the terminal device determines which BWP is currently activated, the terminal device may determine the corresponding scheduling request configuration information according to the BWP, and further, the terminal device sends the scheduling request to the network device using the determined scheduling request configuration information. It should be understood that it is also not necessary to configure different scheduling request configuration information for different BWPs in advance, and the terminal device only needs to select one resource on the symbol occupied by the PUCCH in the current BWP to transmit the scheduling request.

Optionally, in this embodiment of the application, in a case that a first BWP in the multiple bandwidth parts BWPs of the terminal device is in an active state, the sending, by the terminal device, a scheduling request to the network device according to the first logical channel and the first BWP includes: under the condition that the first BWP is in an active state, the terminal device determines first scheduling request configuration information corresponding to the first logical channel and the first BWP; and the terminal equipment sends a scheduling request to the network equipment according to the first scheduling request configuration information.

Those skilled in the art will appreciate that the purpose of mapping the logical channels with SR configuration is to enable the network device to know the logical channel that triggered the SR transmission, and thus 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 may be mapped to SR configuration 1, and logical channel b may be mapped to SR configuration 2. Thus, if the network receives the SR of data SR configuration 1, knowing that it is logical channel a triggered, it sends an uplink grant for Numerology 1.

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 two bandwidths, BWP- ｃA and BWP-B, and the network device configures two SR configurations 1 and 2 for the terminal device, and assuming that the terminal device has 3 logical channels available for transmitting datｃA, the network device may configure the mapping table as shown in table 1:

TABLE 1

The network device and the terminal device may subscribe PUCCH resources, PUCCH cycles, or some other parameters related to SR transmission, corresponding to different SR configurations in different BWPs in advance, and the terminal device may pre-store a mapping table between a logical channel and the SR configuration, and once the terminal device selects a logical channel, the terminal device may look up the mapping table to determine the SR configuration corresponding to the selected logical channel, and then the terminal device may send an SR of the currently activated BWP to the network device. The PUCCH-BWP-1-A and the PUCCH-BWP-1-B can have the same PUCCH period but correspond to different frequency domain positions; or the PUCCH periods may be different from each other, or both PUCCH periods may be different from each other, which is not limited in this embodiment.

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

TABLE 2

	BWP-A	BWP-B
			Logical channel 1	SR configuration1-A	SR configuration 1-B
Logical channel 2	SR configuration2-A	SR configuration2-B
			Logical channel 3	SR configuration2-A	SR configuration2-B

Optionally, in this embodiment of the application, the determining, by the terminal device, first scheduling request configuration information corresponding to the first logical channel and the first BWP when the first BWP is in the active state includes: the terminal device determines the first scheduling request configuration information according to the first logical channel and a mapping relation table corresponding to the first BWP, where the mapping relation table includes a correspondence relation between at least one logical channel and at least one scheduling request configuration information, and the at least one logical channel includes the first logical channel.

After the terminal device determines which BWP is currently activated, the terminal device may directly determine ｃA mapping table corresponding to the currently activated BWP, for example, assuming that the currently activated BWP is BWP- ｃA, the mapping table may include ｃA first column and ｃA second column as in table 2, and after obtaining the mapping relationship between the first column and the second column, the terminal device may directly search for the corresponding scheduling request configuration information according to the selected logical channel. If the terminal device selects 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 SR configuration 1-a.

Optionally, in this 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 sends the scheduling request to the network device according to the first scheduling request configuration information, including: the terminal device sends a scheduling request to the network device on the PUCCH resource in the first BWP.

The SR configuration mentioned above includes at least the frequency domain location and/or PUCCH cycle of the PUCCH used for transmitting the SR, as long as the parameters related to transmitting the SR can be within the SR configuration. Once the terminal device determines a kind of scheduling request configuration information, the terminal device transmits a scheduling request to the network device using a parameter included in the scheduling request configuration information. For example, when the terminal device determines that a certain BWP is activated, the terminal device may select a PUCCH resource on the corresponding BWP to transmit an SR by using the mapped SR configuration based on the mapping relationship between the logical channel and the SR configuration, and when a certain logical channel triggers SR reporting.

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

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

Optionally, in an embodiment of the present application, the method further includes: the terminal device receives indication information sent by the network device, where the indication information is used to indicate that the working BWP of the terminal device is to be switched from the second BWP to the first BWP.

Such indication means may include RRC signaling, Downlink Control Information (DCI), or MAC signaling. Or the terminal device may be configured with a timer, that is, it may switch between different BWPs according to a certain time law. When the network device indicates the terminal device to perform handover, that is, the network device may notify the BWP to be activated, for example, the information may be an identifier, or at least one of a center frequency point, bandwidth information, or a basic parameter set of the BWP to be activated.

It should be understood that the interaction between the network device and the terminal device described by the network device and the related characteristics, functions, etc. correspond to the related characteristics, functions of the terminal device. And related matters have been described in detail in the method 100, and are not repeated herein for brevity.
