Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The embodiments of the present invention can be applied to various communication systems, such as Wireless Local Area Network (WLAN), Narrow-Band Internet of Things (NB-IoT), Global System for Mobile Communications (GSM), Enhanced Data rate GSM Evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (Code Division Multiple Access, CDMA2000), Time Division-synchronous Code Division Multiple Access (Time Division-Synchronization Code Division Multiple Access, TD-SCDMA), Long Term Evolution (Long Term Evolution, LTE), satellite communication, and fifth generation (5G) or emerging new communication systems.

Mobile communication technology has profoundly changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. In order to cope with explosive mobile data traffic increase in the future, equipment connection of mass mobile communication, and various new services and application scenes which are continuously emerging, a 5G mobile communication system is produced. The International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc).

Typical eMBB services are: the services include ultra high definition video, Augmented Reality (AR), Virtual Reality (VR), and the like, and these services are mainly characterized by large transmission data volume and high transmission rate. Typical URLLC services are: the main characteristics of the applications of wireless control in industrial manufacturing or production processes, motion control of unmanned automobiles and unmanned airplanes, and haptic interaction such as remote repair and remote operation are that ultra-high reliability, low time delay, less transmission data volume and burstiness are required. Typical mtc traffic is: the intelligent power distribution automation, smart city etc. main characteristics are that networking equipment quantity is huge, transmission data volume is less, data are insensitive to transmission delay, and these mMTC terminals need satisfy the demand of low-cost and very long standby time.

Different services have different requirements on the mobile communication system, and how to better support the data transmission requirements of a plurality of different services simultaneously is a technical problem to be solved by the current 5G mobile communication system. For example, how to support mtc traffic and eMBB traffic simultaneously, or URLLC traffic and eMBB traffic simultaneously.

The study of mtc by the 5G standard has not been extensively conducted.

Currently, a User Equipment (UE) of the mtc service is referred to as a low-complexity UE (reduced capability UE), or a narrow-bandwidth UE, or an internet of things device, or a low-end smart handheld terminal in the standard. This type of UE may be less complex than other UEs in terms of bandwidth, power consumption, number of antennas, etc., e.g., narrower bandwidth, lower power consumption, fewer number of antennas, etc. This type of UE may also be referred to as a lightweight version of terminal equipment (nrlight, NRL). The maximum bandwidth supported by the mMTC user equipment is less than 100 MHz. It should be noted that the mtc ue in the present application is not only a device for machine type communication, but also an intelligent handheld terminal.

The embodiment of the application provides a schematic architecture diagram of a mobile communication system. As shown in fig. 1, the mobile communication system includes radio access network device 120, i.e., network device 120, and at least one terminal device (e.g., terminal device 130 and terminal device 140 and terminal device 150 in fig. 1). The terminal equipment is connected with the wireless access network equipment in a wireless mode, and the wireless access network equipment is connected with the core network equipment in a wireless or wired mode. The core network device and the radio access network device may be separate physical devices, or the function of the core network device and the logical function of the radio access network device may be integrated on the same physical device, or a physical device may be integrated with a part of the function of the core network device and a part of the function of the radio access network device. The terminal equipment may be fixed or mobile. Fig. 1 is a schematic diagram, and other network devices, such as a wireless relay device and a wireless backhaul device, may also be included in the communication system, which are not shown in fig. 1. The embodiments of the present application do not limit the number of core network devices, radio access network devices, and terminal devices included in the mobile communication system.

It should be understood that, in the communication system of the present application, an information sending end may be a network device or a terminal device, and an information receiving end may be a network device or a terminal device, which is not limited in the present application, and only the first type of terminal device may participate in communication in the communication system.

In the embodiment of the present application, a scheme is described by taking a network device and a first terminal device as an example of two interactive parties, which is not limited herein.

The radio access network device is an access device in which the terminal device is accessed to the mobile communication system in a wireless manner, and may be a base station NodeB, an Evolved Node B (eNodeB), a base station in a 5G mobile communication system, a base station in a future mobile communication system, or an access Node in a WiFi system, and the like.

The Terminal device may also be referred to as a Terminal (Terminal), a user equipment UE, a Mobile Station (MS), a Mobile Terminal (MT), etc. The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), 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 smart city (smart city), a wireless terminal in home (smart home), and the like.

The wireless access network equipment and the terminal equipment can be deployed on land, including indoors or outdoors, and are handheld or vehicle-mounted; can also be deployed on the water surface; it may also be deployed on airborne airplanes, balloons, and satellites. The embodiment of the application does not limit the application scenarios of the wireless access network device and the terminal device.

The embodiments of the present application may be applicable to downlink signal transmission, may also be applicable to uplink signal transmission, and may also be applicable to device-to-device (D2D) signal transmission. For downlink signal transmission, the sending device is a radio access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a radio access network device. For D2D signaling, the sending device is a terminal device and the corresponding receiving device is also a terminal device. The embodiment of the present application does not limit the transmission direction of the signal.

The radio access network device and the terminal device, and the terminal device may communicate via a licensed spectrum (licensed spectrum), may communicate via an unlicensed spectrum (unlicensed spectrum), and may communicate via both the licensed spectrum and the unlicensed spectrum. The radio access network device and the terminal device may communicate with each other through a spectrum of 6G or less, may communicate through a spectrum of 6G or more, and may communicate using both a spectrum of 6G or less and a spectrum of 6G or more. The embodiments of the present application do not limit the spectrum resources used between the radio access network device and the terminal device.

For ease of understanding the present application, the random access procedure is briefly described. The random access procedure is as follows:

the terminal device searches for a Synchronization Signal and a physical broadcast channel (SSB), and the terminal device obtains a Master Information Block (MIB) sent by the network device by searching for the SSB. The terminal device obtains a time domain resource and a frequency domain resource of a Control resource set (CORESET) according to the MIB, and the terminal device may detect Downlink Control Information (DCI) of a scheduling System Information Block (SIB) on the CORESET, and receive the SIB1 at a time-frequency position indicated by the DCI, so as to receive an Initial uplink bandwidth part (Initial UL BWP), an Initial Downlink bandwidth part (Initial DL BWP), a random access preamble list, and a random access timing list, which are indicated in the SIB 1.

According to SIB1, the terminal device sends a physical random-access channel (PRACH, Msg1) carrying a random access sequence in a random access occasion (RO) resource associated with the SSB;

if the base station successfully receives the Random access sequence and allows the UE to access, sending RAR (Random access response, RAR) to the UE, namely Msg2, in a window (window) of a pre-configured RAR;

meanwhile, the UE monitors Downlink Control Information (DCI) transmitted on a Physical Downlink Control Channel (PDCCH) in a pre-configured RAR window, where the DCI is used to instruct the UE to acquire RAR information from a Media Access Control (MAC) Protocol Data Unit (PDU) carried by a Physical Downlink Shared Channel (PDSCH).

It should be understood that, if the base station cannot receive the preamble sequence due to reasons such as collision of random access sequences selected among different UEs or poor channel conditions, the base station will not send RAR information, and then the UE will not detect DCI and MAC RAR in the RAR window, and then this random access fails.

After the terminal successfully detects the DCI, the terminal receives a random access response RAR (i.e., Msg2), and sends a Physical Uplink Shared CHannel (PUSCH, Msg3) according to a time-frequency resource indicated by an Uplink grant UL grant in the random access response, the network device sends the DCI to the terminal device, the DCI indicates a time-frequency resource carrying a contention resolution message, Msg4, and the terminal device detects and detects the DCI and receives Msg 4.

It should be noted that, before the Radio Resource Control (RRC) establishes the connection, the UE needs to receive in CORESET 0: a PDCCH for scheduling SIB1, a PDSCH for carrying SIB1, a PDCCH for scheduling SI, a PDSCH for carrying SI, a PDCCH for scheduling Msg2, a PDSCH for carrying Msg2, a PDCCH for scheduling Msg3, a PDCCH for scheduling Msg4, and a PDSCH for carrying Msg 4. Before Radio Resource Control (RRC) establishes a connection, the UE needs to send the PUSCH carrying Msg1 and the PUSCH carrying Msg3 within initial UL BWP.

For the convenience of understanding the embodiments of the present application, the following brief introduction is made to the related concepts involved in the present application:

1. the UE in the present application may be classified into a first type terminal device and a second type terminal device, where the first type terminal device is, for example, a low complexity UE (reduced capability UE, REDCAP UE), and the second type terminal device may be a legacy UE, such as an eMBB UE.

The first type of terminal device and the second type of terminal device have different characteristics, including one or more of:

bandwidth, number of supported or configured resources, number of transmit antenna ports and/or number of receive antenna ports, number of radio frequency channels, number of hybrid automatic repeat request (HARQ) processes, supported peak rate, application scenario, delay requirement, processing capability, protocol version, duplexing mode, service, and the like. The first feature is described in detail below.

The bandwidth, or the channel bandwidth, or the maximum channel bandwidth supported or configured by the terminal device, the bandwidths of the first type terminal device and the second type terminal device are different, for example: the bandwidth of the first type of end device may be 20MHz or 10MHz or 5MHz and the bandwidth of the second type of end device may be 100 MHz. It is understood that with the development of communication technology, the maximum channel bandwidth supported by the first type of terminal device may no longer be 20MHz or 10MHz or 5MHz, but rather evolved into a wider or narrower bandwidth such as 3MHz, 25MHz, 50 MHz.

The number of supported or configured resources, which may be RBs, REs, subcarriers, RB groups, REG bundle, control channel elements, subframes, radio frames, slots, mini-slots and/or number of symbols, may be different for the first type of terminal device and the second type of terminal device, for example: the number of resources supported by the first type of terminal device is 48RB and the number of resources supported by the second type of terminal device is 96 RB.

The number of transmitting antenna ports and/or the number of receiving antenna ports, i.e. the number of transmitting antenna ports and/or the number of receiving antenna ports of the first type of terminal device is different from the second type of terminal device, for example: the number of transmit antenna ports of the first type of terminal device may be 1, the number of receive antenna ports may be 2, the number of transmit antenna ports of the second type of terminal device may be 2, and the number of receive antenna ports may be 4.

The number of the radio frequency channels, that is, the number of the radio frequency channels of the first type terminal device is different from that of the second type terminal device, for example, the number of the radio frequency channels of the first type terminal device may be 1, and the number of the radio frequency channels of the second type terminal device may be 2.

The number of HARQ processes, i.e. the number of HARQ processes supported by the first type of terminal device, is different from the second type of terminal device, for example: the number of HARQ processes for the first type of terminal device may be 8 and the number of HARQ processes for the second type of terminal device may be 16.

The peak rates supported, i.e. the maximum peak rates of the first type of terminal device and the second type of terminal device, are different, for example: the maximum peak rate supported by the first type of terminal device may be 100Mbps and the peak rate supported by the second type of terminal device may be 200 Mbps.

The application scenarios, i.e. the first type of terminal device and the second type of terminal device, are served for different application scenarios, for example: the first type terminal device is applied to industrial wireless sensing, video monitoring, wearable devices and the like, and the second type terminal device is applied to mobile communication, video internet surfing and the like.

The delay requirements, that is, the requirements of the first type terminal device and the second type terminal device for transmission delay are different, for example, the delay requirement of the first type terminal device may be 500 ms, and the delay requirement of the second type terminal device may be 100 ms.

The processing capability, and the processing speed of the first type terminal device and the second type terminal device under different subcarrier spacing (SCS) conditions for the processing timing of the channel or data are different, for example: the first type of terminal device does not support complex operations, which may include: artificial Intelligence (AI), Virtual Reality (VR) rendering, the second type terminal device supporting complex operations, or it being understood that the processing power of the first type terminal device is lower than that of the second type terminal device.

The protocol version, that is, the first type terminal device and the second terminal device belong to terminal devices of different protocol versions, for example: the protocol versions supported by the first type terminal device are Release 17 and the protocol versions after Release 17, and the protocol version supported by the second type terminal device is the protocol version before Release 17, such as Release 15 or Release 16.

Duplex modes, including half duplex and full duplex, for example: the first type of terminal equipment works in a half-duplex mode, and the second type of terminal equipment works in a full-duplex mode.

Services including, but not limited to, internet of things applications such as video surveillance, mobile broadband MBB, etc., such as: the service supported by the first type terminal equipment is time video monitoring, and the service supported by the second type terminal equipment is mobile broadband MBB. The embodiment of the present application does not limit this.

It should be understood that other types of terminal devices, or future new types of terminal devices, which also support the technical solution of the present application are also within the scope of the present application.

The first terminal device in the present application may be an example of a first type terminal device, and the second terminal device may be an example of a second type terminal device.

2. Initial downlink bandwidth part (Initial downlink bandwidth part, Initial DL BWP): it is indicated in SIB1 that the frequency range contains CORESET, but will take effect only after Msg4 reception is complete.

3. Initial uplink bandwidth part (Initial UL BWP): in SIB1, it is indicated that HARQ-ACK feedback for the uplink channels PRACH, Msg3, Msg4 involved in the initial access procedure are all performed in the range of initial UL BWP.

CORESET control resource set. The terminal device is receiving downlink control information or downlink data information in the CORESET. When the terminal device and the opposite terminal device do not establish RRC connection, the receiving frequency range of the downlink control channel and the downlink data channel is in CORESET 0.

It should be understood that a low complexity terminal device is a relative concept and the application is not limited in this regard. By way of example, a new terminal device that may be developed in the future may have a feature that is more complicated than an existing legacy UE in at least one of a bandwidth, the number of antennas, a device power consumption, and the like, and at that time, the legacy UE will be a first type terminal device in this application, and the new terminal device will be a second type terminal device in this application, and the embodiments of this application are still applicable and are within the scope of this application.

5. Center frequency: centre frequency of a resource block, or resource block with index in bandwidth as centre

Starting Resource Block (RB): the smallest indexed resource block within the bandwidth, or the first resource block within the bandwidth.

End Resource Block (RB): the resource block with the largest index in the bandwidth, or the last resource block in the bandwidth.

It should be understood that the resource in this application may be a symbol, or a slot, or a mini-slot, or a subframe, etc. The resource in the present application may also be a subcarrier, or a resource block, or a carrier, or a channel control element, etc.

When the resource is a symbol in the present application, the resource unit may be a slot, or a short slot, or a subframe. When the resource in the present application is a subcarrier, the resource unit is a resource block, or a carrier, or a channel control element, etc.

To facilitate understanding of the embodiments of the present application, an explanation of the related terms is made in advance.

In the present application, the first resource and the first bandwidth are different expressions of a resource in the same frequency range. For example, the first resource or first bandwidth may be an upstream BWP; for example, the first resource or first bandwidth may be a downlink BWP; for example, the first resource or first bandwidth may be an initial downlink BWP; for example, the first resource or first bandwidth may be an initial upstream BWP; for example, the first resource or the first bandwidth may be a block of resources having a resource size equal to or smaller than a maximum channel bandwidth supported by the first terminal device. The first set of control resources is expressed as CORESET a, e.g., CORESET a is CORESET0 prior to RRC connection establishment; for example, before or after the RRC connection establishment, CORESET a may also be a common CORESET, and at least one RB of the common CORESET may not be within the range of CORESET0, i.e., CORESET a and CORESET0 may be different CORESETs.

In the present application, the size of the first resource or the first bandwidth is equal to or smaller than the maximum channel bandwidth supported by the first terminal device, and the size may be predefined or indicated by the network device. For example, the size may be 5MHz, or the number of RBs corresponding to 5MHz at different subcarrier spacing, or 10MHz, or the number of RBs corresponding to 10MHz at different subcarrier spacing, or 20MHz, or the number of RBs corresponding to 20MHz at different subcarrier spacing. The first resource or first bandwidth may be understood as a resource that the network device individually configures for the first terminal device, the resource comprising a frequency bandwidth range (e.g. number of RBs), and/or a location in frequency. E.g. resources indicated by a field in the higher layer signalling or physical layer signalling, which is dedicated to the first terminal device. For example, the first control resource set is CORESET0, the first resource or the first bandwidth is an initial upstream BWP, and the first terminal device determines the position of the initial upstream BWP according to the position of CORESET0, which can be understood as: the initial upstream BWP is a resource used by the first terminal device to send upstream information, and the resource may be shared with the second type terminal device or not shared with the second type terminal device (i.e. the initial upstream BWP is an initial upstream BWP dedicated to the first type terminal device).

For a first terminal device without the capability of performing downlink reception and uplink transmission simultaneously, the first terminal device needs to perform downlink reception and uplink transmission in a time division manner. For example, the first terminal device is a time division duplex TDD UE without the capability of simultaneous downlink reception and uplink transmission. For another example, the first terminal device is a half-duplex first terminal device that is not capable of simultaneous downlink reception and uplink transmission. It is assumed that the first terminal device performs downlink reception in the first set of control resources and then performs uplink transmission in the initial first resource. If the frequency range of the first control resource set and the frequency range of the first resource correspond to each other in frequency and exceed the maximum channel bandwidth of the UE, the first terminal device needs to perform frequency tuning after downlink reception, and then perform uplink transmission in the first resource.

Similarly, the first terminal device performs uplink transmission in the first resource and then performs downlink reception in the first control resource set. If the frequency range corresponding to the frequency range of the first resource and the frequency range of the first control resource set in terms of frequency exceeds the maximum channel bandwidth of the first terminal device, the first terminal device needs to perform frequency tuning after uplink transmission, and then downlink reception is performed in the first control resource set.

Frequency tuning can reduce the symbols available for data transmission, reduce resource utilization efficiency, increase power consumption of the first set of control resources, and complexity of implementation of the first set of control resources. In order to solve the above problem, an embodiment of the present application proposes a method of transmitting information, as shown in (a) of fig. 2,

200: the network equipment configures a first control resource set;

it should be appreciated that step 200 is optional and that the first set of control resources may also be predefined. The network device may configure the first control resource set for the terminal device through signaling such as a Master Information Block (MIB).

201: the first terminal equipment determines a first control resource set;

it is to be understood that the information of the first set of control resources may be predefined or may be signaled by the network device to the first terminal device. This is not a limitation of the present application. For example, the first terminal device determines the size and location of the first set of control resources, e.g., via MIB signaling.

202: the first terminal device determines the location of the first resource according to the location of the first control resource set, and the first resource may include a first downlink resource and/or a first uplink resource.

When the first resource includes a first downlink resource and a first uplink resource, as shown in (b) in fig. 2, a total frequency range of the first uplink resource and the frequency range of the first downlink resource does not exceed the maximum channel bandwidth of the first terminal device.

203: the first terminal device sends the uplink information through the first resource, or 204: the first terminal equipment receives the downlink information through the first resource.

Wherein a total frequency range of the first resource corresponding in frequency to the frequency range of the first set of control resources does not exceed a maximum channel bandwidth of the first terminal device.

The first terminal device determines the location of the first resource according to the location of the first control resource set, which may be the location of the first resource determined according to the location of the first control resource set and the first offset.

Specifically, the position of the first control resource set may be the a-th RB of the first control resource set, or a starting subcarrier of the a-th RB of the first control resource set, or a center frequency (or a center subcarrier) of the a-th RB of the first control resource set, or a last subcarrier of the a-th RB of the first control resource set, or a starting CCE of the first control resource set, or a starting REG of the first control resource set, or a starting symbol of the first control resource set, or a starting slot of the first control resource set, and the like.

Wherein A is a positive integer, or A is a predetermined positive integer. For example, a ═ 1, or a ═ X/2+ 1. Wherein X is the size of the first control resource set and is in RB.

That is, the position of the first control resource set may be the 1 st RB of the first control resource set, may be the starting subcarrier or the center subcarrier or the last subcarrier of the 1 st RB of the first control resource set. For example, the A < th > RB of the first control resource set is an RB of the first control resource set with an RB index of A-1.

The location of the first resource may be the Z th RB of the first resource, or the starting subcarrier of the Z th RB of the first resource, or the center frequency (or center subcarrier) of the Z RBs of the first resource, or the last subcarrier of the Z th RB of the first resource.

Wherein Z is a positive integer. For example, Z ═ 1, or Z ═ L/2+ 1. Wherein L is the size of the first resource and is in units of RBs. Wherein, L is the number of RBs included in the first resource, and X is the number of RBs included in the first control resource set.

That is, the position of the first resource may be the 1 st RB of the first resource, or may be the starting subcarrier or the center subcarrier or the last subcarrier of the 1 st RB of the first resource. For example, the Z-th RB of the first resource is an RB of the first resource having an RB index of Z-1.

The first offset is the interval between the location of the first set of control resources and the location of the first resource, and there are two possibilities: the offset is 0, that is, the position reference point (i.e., the first position) of the selected first control resource set is aligned with the position reference point (i.e., the second position) of the selected first resource, for example, the positions of the 1 st RB of the first control resource and the 2 nd RB of the first resource may be the same; the offset is not 0, i.e. the position of the selected first control resource set is not aligned with the position of the selected first resource, e.g. the position of the 1 st RB of the first control resource may be different from the position of the 6 th RB of the first resource.

It will be appreciated that the value of the offset depends on the choice of the location of the first control resource set and the location of the first resource. For example, when the center frequencies of the first control resource and the first resource are the same and the sizes are the same, the center frequency of the first control resource set is selected as the position of the first control resource set, and the center frequency of the first resource is selected as the position of the first resource, then the offset is 0; for another example, when the 3 rd RB of the first control resource set is selected as the position of the first control resource set, and the 1 st RB of the first resource is selected as the position of the first resource, the offset is not 0.

It should be understood that location herein may be a general term for a location reference point. For example, the location of the first controlling resource set may be a general name of a location reference point of the first controlling resource set, and the location of the first resource may be a general name of a location reference point of the first resource.

It is to be understood that the choice of the location reference point of the first controlling resource set may be different from the choice of the location reference point of the first resource, i.e. Z and a may be different, i.e. the location of the first controlling resource set may be the 1 st RB of the first controlling resource set and the location of the first resource may be the 3 rd RB of the first resource. This is not a limitation of the present application. For example, Z may be equal to a. For example, Z ═ a ═ 1. However, Z may not be equal to A. For example, Z ═ X and a ═ 1.

The total frequency range of the first control resource set corresponding in frequency to the frequency range of the first resource is less than or equal to the maximum channel bandwidth of the first terminal device may be expressed in that the bandwidth between the starting position of the first control resource set (which may be the first RB) and the ending position of the first resource (which may be the last RB) is less than or equal to the maximum bandwidth supported by the first terminal device, or the bandwidth between the ending position of the first control resource set (which may be the last RB) and the starting position of the first resource (which may be the first RB) is less than or equal to the maximum bandwidth supported by the first terminal device.

It should be understood that the first set of controlling resources may or may not overlap with the first resource, and the first set of controlling resources may be CORESET 0.

The first offset may be defined as a separation between a first location of the first set of control resources and a second location of the first resource. For example, the first offset is N RBs. As shown in fig. 3, the first position of the first control resource set is the 1 st RB, and the second position of the first resource is the 1 st RB, i.e., Z ═ a ═ 1.

In particular, where the first offset is 0, the location of the second location of the first resource can be determined directly from the first location of the first set of control resources. The second position may be calculated by: the position of the second position is equal to the position of the first position + the first offset N.

Specifically, N may be predefined, or N is indicated to the first terminal device by the network device through the first signaling, which is not limited in this application. Illustratively, the first signaling may be a SIB 1.

The value of N may determine the first offset according to at least one of a size of the first control resource set, a size of the first bandwidth, and a maximum channel bandwidth supported by the first terminal device.

Illustratively, N may be a predefined integer including 0, a positive integer, a negative integer.

Take the example that the first location of the first set of control resources is the 1 st RB of the first set of control resources and the second location of the first resource is the 1 st RB of the first resource.

The value of N is equal to 0 (as in fig. 3 (a)). The offset between the first RB of the first control resource set and the first RB of the first resource is 0, and when the frequency range of the first resource includes the frequency range of the first control resource set in frequency, the last RB of the first resource is located at the upper boundary of the frequency, so that from the perspective of the network device, there are more resources for information transmission, and the flexibility of scheduling is increased, and from the perspective of the terminal device, the increase of power consumption of the terminal device caused by frequency modulation can be avoided.

For example, the value of N is equal to X-L (as in (c) of FIG. 3). The offset is X-L, when the last RB of the first control resource set is the same as the last RB of the first resource in frequency, and the frequency range of the first resource comprises the frequency range of the first control resource set in frequency, the X-L corresponds to the lower bound of the first RB of the first resource in frequency, so that more resources are used for information transmission from the perspective of network equipment, the scheduling flexibility is increased, and the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided from the perspective of the terminal equipment.

For example, the value of N is equal to (X-L)/2 or floor ((X-L)/2) (see (b) in FIG. 3). The center RB of the first control resource set is the same as the center RB of the first resource in frequency, the offset is (X-L)/2 or floor ((X-L)/2), and when the frequency range of the first resource includes the frequency range of the first control resource set in frequency, the first control resource set is located in the center of the first resource, and there are more resources for information transmission from the perspective of the network device, so that the scheduling flexibility is increased, and the increase of the power consumption of the terminal device caused by frequency modulation is avoided from the perspective of the terminal device.

For example, the value of N is equal to-L (see (d) in FIG. 3). When the first RB of the first control resource set is adjacent to the last RB of the first resource, the offset is N-L, and when the frequency range of the first resource is not overlapped with the first control resource set in terms of frequency, N-L corresponds to the lower bound of the position of the first resource, and from the perspective of the network device, there are more resources for information transmission, so that the scheduling flexibility is increased, and from the perspective of the terminal device, the increase of the power consumption of the terminal device caused by frequency modulation is avoided. Meanwhile, the frequency range of the first resource is not overlapped with the first control resource set in frequency, so that the problem that the resource of the first control resource set is limited in distribution or congested in use can be avoided

For example, the value of N is equal to X (e in fig. 3). When the last RB of the first control resource set is adjacent to the first RB of the first resource, the offset is N-L, and when the frequency range of the first resource is not overlapped with the first control resource set in terms of frequency, N-X corresponds to the upper bound of the position of the first resource, from the perspective of the network device, there are more resources for information transmission, increasing the flexibility of scheduling, and from the perspective of the terminal device, avoiding the increase of the power consumption of the terminal device caused by frequency modulation. Meanwhile, the frequency range of the first resource is not overlapped with the first control resource set in frequency, so that the problem that the resource of the first control resource set is limited in distribution or congested in use can be avoided

For example, the value of N can also be any positive or negative integer, for example, the value of N can be divided evenly by the power of 2.

Illustratively, N may be a predefined integer including 0, a positive integer, a negative integer. The value of N is the same as the value of one element in the first set. The first set comprises at least one or more values of {0, X-L, (X-L)/2, -L, X }, or the first set comprises at least one or more values of {0, X-L, floor ((X-L)/2, -L, X }.

For example, the first set includes {0, X-L) }. When the value range of N is the set, the first set is the maximum frequency range that can be covered when the frequency range of the first resource includes the frequency range of the first control resource set in terms of frequency. From the perspective of network equipment, more resources are used for information transmission, the scheduling flexibility is increased, and from the perspective of terminal equipment, the increase of power consumption of the terminal equipment caused by frequency modulation is avoided.

For example, the first set includes {0, (X-L)/2, (X-L) }, or the first set includes {0, floor ((X-L)/2), (X-L) }. When the value range of N is the set, the first set is the maximum frequency range that can be covered when the frequency range of the first resource includes the frequency range of the first control resource set in terms of frequency. From the perspective of network equipment, more resources are used for information transmission, the scheduling flexibility is increased, and from the perspective of terminal equipment, the increase of power consumption of the terminal equipment caused by frequency modulation is avoided.

For example, the first set includes {0, (X-L)/2, (X-L), X }, or the first set includes {0, floor ((X-L)/2), (X-L), X }. For example, the first set includes {0, (X-L)/2, (X-L), -L }, or the first set includes {0, floor ((X-L)/2), (X-L), -L }. For example, the first set includes {0, (X-L)/2, (X-L), X, -L }, or the first set includes {0, floor ((X-L)/2), (X-L), X, -L }. When the value range of N can be the set, the value of N in the first set satisfies: the frequency range of the first resource includes in frequency a frequency range of the first set of control resources, and the frequency range of the first resource includes in frequency a frequency range of the first set of control resources. The network equipment has more resources for information transmission, and can obtain the maximum scheduling flexibility. From the perspective of the terminal equipment, the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided.

Illustratively, N may be indicated by the network device to the first terminal device through the first signaling. The network device indicates the value of N in the K values through a first signaling. At least T of the K values are the same as the T elements in the first set, wherein K is a positive integer, T is a positive integer, and K is greater than or equal to T. The first set comprises at least one or more values of {0, X-L, (X-L)/2, -L, X }, or the first set comprises at least one or more values of {0, X-L, floor ((X-L)/2, -L, X }. It is understood that the values of K-T elements of the K values may be different from the values of {0, X-L, (X-L)/2, -L, X } or {0, X-L, floor ((X-L)/2), -L, X }. For example, the values of the K-T elements may be positive integer multiples of power of 2, or may be negative integer multiples of power of 2. It is understood that when K equals T, K values are all values from {0, X-L, (X-L)/2, -L, X }, or K values are all values from {0, X-L, floor ((X-L)/2), -L, X }.

That is, the set indicated to the first terminal device includes at least one value that N can take.

Illustratively, N is indicated by the network device to the first terminal device via the first signaling. The network device indicates the value of N in the second set by the first signaling. The second set comprises at least one or more values of {0, X-L, (X-L)/2, -L, X }, or the second set comprises at least one or more values of {0, X-L, floor ((X-L)/2, -L, X }. For example, the second set includes {0, X-L }; the network device indicates the value of N in the second set using 1 bit. For example, the second set includes {0, X-L, (X-L)/2}, or the second set includes {0, X-L, floor ((X-L)/2) }; the network device indicates the value of N in the second set using 2 bits. For example, the second set includes {0, X-L, (X-L)/2, -L }, or the second set includes {0, X-L, floor ((X-L)/2), -L }; the network device indicates the value of N in the second set using 2 bits. For example, the second set comprises {0, X-L, (X-L)/2, -L, X }, or the second set comprises {0, X-L, floor ((X-L)/2), -L, X }; the network device indicates the value of N in the second set using 3 bits. It should be understood that the value or the value set of N may be indicated to the first terminal device by the network device through signaling, or may be predefined. If the first terminal device does not receive the first signaling, a default value of N is adopted, and the default value of N may be one of 0, X-L, (X-L)/2, floor ((X-L)/2), -L, and X.

It should be understood that the first signaling may indicate the value of N, indicate an index corresponding to the value of N, indicate an index of a row in a table of values of N (in the table of values of N, the values of N are different when the rows are different), or indicate an index of a column (in the table of values of N, the values of N are different when the rows are different). The element in the table formed by the values of N is the value of N, or the first signaling may indicate an index corresponding to a set in the table formed by the value set of N, which is not limited in the present application.

In one possible embodiment, the first offset is related to a reference subcarrier spacing, and the first offset may be determined according to the reference subcarrier spacing.

The reference subcarrier spacing may be a subcarrier spacing of the first set of control resources, or may be a smaller subcarrier spacing of the first set of control resources and the first resource, or may be a larger subcarrier spacing of the first set of control resources and the first resource.

Illustratively, the subcarrier spacing of the first set of control resources is less than or equal to the subcarrier spacing of the first resource, e.g., the subcarrier spacing of the first resource is an nth power of 2 of the subcarrier spacing of the first set of control resources. If the reference subcarrier spacing is the subcarrier spacing of the first control resource set, the value of N includes 0, a positive integer, and a negative integer; for example, the value of N is equal to 0 (fig. 4(a) below). The value of N being equal to X-2 ⁿ L (e.g., (c) in fig. 4); for example, the value of N is equal to (X-2) ⁿ L)/2 (as in fig. 4 (b)); for example, the value of N is equal to-2 ⁿ L (as in (d) of fig. 4); for example, the value of N is equal to X (as in (e) of fig. 4).

If the reference subcarrier spacing is the subcarrier spacing of the first resource, the value of N may be 0, may be a positive integer, and may be a negative integer; for example, the value of N is equal to 0 (as in (a) of fig. 5). For example, the value of N is equal to 2 ^-n X-L (as in (c) of fig. 5). For example, the value of N is equal to (2) ^-n X-L)/2 (as shown in fig. 5 (b)). For example, the value of N is equal to-L (see (d) in FIG. 5). For example, the value of N is equal to 2 ^-n X (as in (e) of fig. 5).

Illustratively, the subcarrier spacing of the first resource is less than or equal to the subcarrier spacing of the first set of control resources. For example, the subcarrier spacing of the first set of control resources is the subcarrier spacing of the first resource to the power of 2 n.

If the reference subcarrier spacing is the subcarrier spacing of the first control resource set, the value of N includes 0, a positive integer, and a negative integer; for example, the value of N is equal to 0 (as shown in fig. 5 (a) below); for example, the value of N is equal to 2 ^-n X-L (e.g., (c) in fig. 5); for example, the value of N is equal to (2) ^-n X-L)/2 (as in (b) of fig. 5); for example, the value of N is equal to-L (see (d) in FIG. 5); for example, the value of N is equal to 2- ⁿ X (as in fig. 5 (e)).

If the reference subcarrier spacing is the subcarrier spacing of the first resource, the value of N includes 0, a positive integer, and a negative integer; for example, the value of N is equal to 0 (as in (a) of fig. 4). The value of N being equal to X-2 ⁿ L (e.g., (c) in fig. 4); for example, the value of N is equal to (X-2) ⁿ L)/2 (as in fig. 4 (b)); for example, the value of N is equal to-2 ⁿ L (as in (d) of fig. 4); for example, the value of N is equal to X (as in (e) of fig. 4).

It should be understood that the value of N may be predefined or indicated by the network device, and the indication method is similar to the foregoing and will not be described herein again.

In another possible embodiment, the first terminal device determines the location of the first resource according to the location of the first control resource set and the first association relationship. The first association refers to an association of a position of the first control resource set and a first offset corresponding thereto.

It should be understood that the location of the first set of control resources and the first association relationship may be indicated to the first terminal device by the network device through signaling, and if the first signaling is not received by the first terminal device, a default value of N is adopted, where the default value of N is one of 0, X-L, (X-L)/2, floor ((X-L)/2), -L, and X.

The location and the first association of the first set of control resources may also be predefined.

The first terminal device determines a location of the first control resource set, which may be determined according to the first association.

It should be understood that the first association relationship may include a value of the first offset, may also include a value set of the first offset, and may also include a value or a value set of the first offset when referring to the subcarrier spacing.

The frequency range of the first resource and the frequency range of the first control resource set correspond to each other in frequency, and the frequency range does not exceed the maximum channel bandwidth supported by the first terminal device, and for a UE which does not have the capability of simultaneously performing downlink reception and uplink transmission, frequent frequency tuning between uplink transmission and downlink reception can be avoided, and/or frequent frequency tuning between downlink reception and uplink transmission can be avoided, so that available symbols for data transmission are promoted, the resource utilization efficiency is promoted, the power consumption of the terminal device is prevented from being increased, and the implementation complexity of the terminal device is reduced. According to the method and the device, the offset is indicated in the form of the RB, the first terminal equipment can directly determine the position of the first resource through the RB index or the offset RB quantity, and the terminal is simpler to realize. The frequency range of the first resource corresponds to the frequency range of the first control resource set in frequency, and does not exceed the maximum channel bandwidth of the first terminal device, which can also be understood as: the center frequency of the first control resource set is the frequency range of the maximum channel bandwidth supported by the first terminal device covered by the center, including the frequency range of the first resource.

In another possible implementation manner, the determining, by the first terminal device, the location of the first resource according to the location of the first control resource set may specifically include: the first terminal device determines the position of the first resource according to the position of the first control resource set and a second association relationship, where the second association relationship may be that the position of the first control resource set is aligned with the position of the first resource.

For example, the second association may be association 1: the position of the 1 st RB of the first control resource set is the same as the position of the 1 st RB of the first resource, or the predefined association relationship is that the position of the 1 st RB index of the first control resource set is the same as the position of the 1 st RB index of the first resource, or the predefined association relationship is that the position of the starting subcarrier of the 1 st RB of the first control resource set is the same as the position of the starting subcarrier of the 1 st RB of the first resource, as shown in (a) of fig. 3, where (a) of fig. 3 explains association relationship 1 by taking CORESET0 and initial UL BWP as examples. Under the condition that the frequency range of the first resource comprises the frequency range of the first control resource set in frequency, the position of the last RB of the first resource is at the upper limit of the frequency, more resources are used for information transmission from the perspective of network equipment, the scheduling flexibility is increased, and the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided from the perspective of the terminal equipment

For example, the second association may be association 2: the center frequency of the first control resource set and the center frequency (center subcarrier) of the first resource are located at the same position, or the X/2 th RB of the first control resource set and the L/2 th RB of the first resource are located at the same position, or the center frequency (center subcarrier) of the X/2 th RB of the first control resource set and the center frequency (center subcarrier) of the L/2 th RB of the first resource are located at the same position. Fig. 3 (b) illustrates association 2 by taking CORESET0 and initial UL BWP as an example. Under the condition that the frequency range of the first resource comprises the frequency range of the first control resource set in frequency, the first control resource set is positioned in the center of the first resource, more resources are used for information transmission from the perspective of network equipment, the scheduling flexibility is increased, and the increase of power consumption of the terminal equipment caused by frequency modulation is avoided from the perspective of the terminal equipment.

For example, the second association may be association 3: the RB with the largest index of the first control resource set and the RB with the largest index of the first resource are in the same position, or the Xth RB of the first control resource set and the Lth RB of the first resource are in the same position. Fig. 3(c) explains the association 3, taking CORESET0 and initial UL BWP as an example. Under the condition that the frequency range of the first resource comprises the frequency range of the first control resource set in frequency, the position of the first RB of the first resource is at the lower boundary of the frequency range, more resources are used for information transmission from the perspective of network equipment, the scheduling flexibility is increased, and the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided from the perspective of the terminal equipment.

For example, the second association relationship may be that the association relationship is association relationship 4: the position of the first set of control resources is spaced from the position of the first resource by N RBs, with the value of N being 0. For example, the 1 st RB of the first set of control resources is located adjacent to the L < th > RB of the first resource. Fig. 3 (d) illustrates association 4 by taking CORESET0 and initial UL BWP as an example. Under the condition that the frequency range of the first resource is not overlapped with the first control resource set in terms of frequency, the lower bound of the position of the first resource has more resources for information transmission from the angle of network equipment, so that the scheduling flexibility is increased, and the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided from the angle of the terminal equipment. Meanwhile, the frequency range of the first resource is not overlapped with the first control resource set in frequency, so that the problem that the resource of the first control resource set is limited in allocation or congested in use can be avoided.

For example, the second association relationship may be that the association relationship is association relationship 5: the position of the first set of control resources is separated from the position of the first resource by N RBs, with the value of N being 0. For example, the xth RB of the first set of control resources is located adjacent to the 1 st RB of the first resource. Fig. 3 (e) illustrates association 5 by taking CORESET0 and initial UL BWP as an example. Under the condition that the frequency range of the first resource is not overlapped with the first control resource set in frequency, more resources are used for information transmission from the angle of network equipment at the upper bound of the position of the first resource, the scheduling flexibility is increased, and the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided from the angle of the terminal equipment. Meanwhile, the frequency range of the first resource is not overlapped with the first control resource set in frequency, so that the problem that the resource of the first control resource set is limited in allocation or congested in use can be avoided.

It should be understood that the second association relationship may be predefined, or may be indicated by the network device through signaling, and the signaling may be SIB 1.

In a possible embodiment, the network device indicates the second association relationship by signaling.

The network device may indicate the association by 1 bit. For example, the network device indicates the second association in association 1 and association 3. Alternatively, the network device indicates the second association in association 4 and association 5. The first set is of a maximum frequency range that can be covered if the frequency range of the first resource comprises in frequency the frequency range of the first set of control resources. From the perspective of network equipment, more resources are used for information transmission, the scheduling flexibility is increased, and from the perspective of terminal equipment, the increase of power consumption of the terminal equipment caused by frequency modulation is avoided.

For example, the network device indicates the association relationship by 2 bits. For example, the network device indicates the first association among

associations

1, 2, 3. The first set is of a maximum frequency range that can be covered if the frequency range of the first resource comprises in frequency the frequency range of the first set of control resources. From the perspective of network equipment, more resources are used for information transmission, the scheduling flexibility is increased, and from the perspective of terminal equipment, the increase of power consumption of the terminal equipment caused by frequency modulation is avoided.

For example, the network device indicates the association relationship by 2 bits. For example, the network device indicates a first association in

associations

1, 2, 3, 4, or a second association in

associations

1, 2, 3, 5. The frequency range of the first resource includes in frequency a frequency range of the first set of control resources, and the frequency range of the first resource includes in frequency a frequency range of the first set of control resources. The network equipment has more resources for information transmission, and can obtain the maximum scheduling flexibility. From the perspective of the terminal equipment, the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided.

For example, the network device indicates the association relationship by 3 bits. For example, the network device indicates the second association among the

associations

1, 2, 3, 4, 5. The frequency range of the first resource includes in frequency a frequency range of the first set of control resources, and the frequency range of the first resource includes in frequency a frequency range of the first set of control resources. The network equipment has more resources for information transmission, and can obtain the maximum scheduling flexibility. From the perspective of the terminal equipment, the increase of the power consumption of the terminal equipment caused by frequency modulation is avoided.

After receiving the indication of the network device, the first terminal device may determine the location of the first resource according to the second association relationship.

In yet another possible embodiment, the first terminal device determines the location of the first resource from the locations of the plurality of candidate resources, which may also be understood as the terminal device determining the first resource from the plurality of candidate resources.

From the perspective of the network device, the network device may configure a plurality of candidate bandwidths for the first terminal device, and more resources may be used for downlink data transmission, thereby improving flexibility of resource allocation and avoiding resource congestion. From the perspective of the terminal device, the terminal device has a plurality of candidate bandwidths available for transmitting information, and the terminal device can determine the position of one of the first resources according to the rule, so that the flexibility of the terminal device in transmitting information is improved. From the view of the terminal device, the terminal device in the first type of terminal device may be divided into a plurality of subtypes, the first terminal device belongs to one of the subtypes, the candidate resources corresponding to different subtypes are different, and the correspondence may be predefined or indicated by the network device through the third signaling. For example, the first type of terminal device is divided into 2 sub-types, a terminal device of sub-type 1 corresponds to candidate resource 1, and a terminal device of sub-type 2 corresponds to candidate resource 2.

Illustratively, the locations of the M candidate resources are determined from the locations of the first set of control resources and the M offsets. The M offsets correspond to the M candidate resources. The index of the M candidate resources may be 0, 1, … … M-1, with the index of the M offsets being 0, 1, … …, M-1. Offset N corresponding to mth candidate resource _m-1 In which N is _m-1 Is the number of RBs between the location of the first set of control resources and the location of the mth candidate resource, where m is a positive integer, 1<＝m<M. The M candidate bandwidths include at least two second resources, the two second resources having the same size and different N. For example, the M candidate bandwidths include 3 second resources, the size of the second resource with index 1 is 5MHz or the number of RBs corresponding to 5MHz, the size of the second resource with index 2 is 20MHz or the number of RBs corresponding to 20MHz, the size of the second resource with index 3 is 20MHz or the number of RBs corresponding to 20MHz, and the offset of the second resource with index 1 is N ₁ The offset of the second resource with index 2 is N ₂ The offset of the second resource with index 3 is N ₃ ，N ₂ Is not equal to N ₃ . Second resource of the same size, N ₂ And N ₃ Can correspond to different frequency positions, and has more resources from the network sideFor transmitting information, thereby increasing flexibility in resource allocation.

And the first terminal equipment receives the second signaling indicated by the network equipment. In an alternative approach, the second signaling indicates the value of M. The size of each of the M candidate resources is predefined and equal to or smaller than a maximum channel bandwidth supported by the first terminal device. For example, the size of each of the M candidate resources is 5MHz, or 10MHz, or 20MHz, or the number of RBs corresponding to 5MHz, or the number of RBs corresponding to 10MHz, or the number of RBs corresponding to 20 MHz. In another alternative, the second signaling indicates the value of M and the size of the M candidate resources.

In one possible approach, the M offsets may be indicated by the first signaling. In another possible approach, a value of at least one of the M offsets is indicated by the first signaling, and the value of the at least one of the M offsets is predefined. For example, the M offsets are 3 offsets, wherein 1 offset is indicated by the first signaling, wherein 2 offsets are predefined. In another possibility, either the M offsets are predefined. Offset N corresponding to mth candidate bandwidth _m-1 In which N is _m-1 Is the number of RBs between the location of the first set of control resources and the location of the mth candidate bandwidth, 1<＝m<M. The candidate bandwidths with the same size can correspond to different offsets, and the positions of the candidate bandwidths are different, so that more flexible resource allocation is facilitated, and resource congestion is reduced.

The determination method of N and possible values of N may refer to the methods in the above embodiments, and are not described herein again.

In a possible manner, the first terminal device receives a third signaling sent by the network, where the third signaling indicates that the first terminal device determines the first resource among the M candidate resources, and the first terminal device determines the location of the first resource used by the first terminal device according to the location of the first control resource set and the offset corresponding to the first resource. In another possible mode, the first terminal device determines the first resource among the M candidate resources according to a predefined rule, and the first terminal device determines the position of the first resource of the first terminal device according to the position of the first control resource set and an offset corresponding to the first resource.

Illustratively, the locations of the M candidate resources may also be determined from the location of the first set of control resources and the Y offsets. The Y offsets correspond to the M candidate resources. The index of the M candidate resources may be 0, 1, … … M-1, and the index of the Y offsets may be 0, 1, … …, Y-1. The M candidate resources include at least two candidate resources with different sizes and the same N, and may also include at least two candidate resources with different sizes and the same offset N. For example, the M candidate resources include 3 candidate resources with index 1, the 3 resource size is 5MHz or the number of RBs corresponding to 5MHz, the candidate resource size with index 2 is 20MHz or the number of RBs corresponding to 20MHz, the candidate resource size with index 3 is 20MHz or the number of RBs corresponding to 20MHz, and the offset of the candidate resource with index 1 is N ₁ The offset of the third bandwidth with index 2 is N ₁ The offset of the third resource with index 3 is N ₂ ，N ₁ Is not equal to N ₂ . For candidate resources with different sizes but the same N value, in different scenarios, the first terminal device may transmit information through the candidate resource with index 1 or the candidate resource with index 2, and the candidate resource with smaller size may be used in the scenario where the first terminal device needs to save power consumption, which is beneficial to reducing the power consumption of the first terminal device. Candidate resources with different positions and the same size or with different sizes and the same positions can be selected, so that the selection range of the first resource is expanded, flexible allocation of the resources is facilitated, and resource congestion is reduced.

And the first terminal equipment receives the second signaling indicated by the network equipment. In an alternative approach, the second signaling indicates the value of M. The size of each of the M candidate resources is predefined and equal to or smaller than the maximum channel resource supported by the first terminal device. For example, the size of each of the M candidate resources is 5MHz, or 10MHz, or 20MHz, or the number of RBs corresponding to 5MHz, or the number of RBs corresponding to 10MHz, or the number of RBs corresponding to 20 MHz. In another alternative, the second signaling indicates the value of M and the size of the M candidate resources.

In a possible manner, at least one of the Y offsets corresponds to more than one candidate resource, that is, candidate bandwidths with different sizes may have the same position. For example, 1 offset in the Y offsets corresponds to 2 candidate resources, and the offsets of the 2 candidate resources are the same, and the sizes of the candidate resources may be different. The values of the Y offsets are indicated by the first signaling. In another possibility, a value of at least one of the Y offsets is indicated by the first signaling, and the value of at least one of the Y offsets is predefined. For example, the Y offsets are 3 offsets, wherein 1 offset is indicated by the first signaling, wherein 2 offsets are predefined. In another possibility, either the Y offsets are predefined. The value of N may be determined or indicated by the above method, which is not described herein again.

In a possible manner, the first terminal device receives a third signaling indicated by the network, where the third signaling indicates a first resource in the M candidate resources, and the first terminal device determines a location of the first resource of the first terminal device according to a location of the first control resource set and an offset corresponding to the first resource. In another possible manner, the first terminal device determines the first resource among the M candidate resources according to a predefined rule, and the first terminal device determines the location of the first resource according to the location of the first control resource set and an offset corresponding to the first resource.

The first signaling, the second signaling and the third signaling can be different fields in the same signaling; or, the first signaling, the second signaling, and the third signaling are different signaling, for example, the first signaling may be SIB1, a PDCCH scheduling SIB1, a PDCCH scheduling Msg2, Msg2, a PDCCH scheduling Msg3, and a PDCCH scheduling Msg 4. The second signaling may be SIB1, PDCCH scheduling SIB1, PDCCH scheduling Msg2, Msg2, PDCCH scheduling Msg3, PDCCH scheduling Msg 4. The third signaling may be SIB1, PDCCH scheduling SIB1, PDCCH scheduling Msg2, Msg2, PDCCH scheduling Msg3, PDCCH scheduling Msg 4. (ii) a Or at least two of the first signaling, the second signaling, and the third signaling are different signaling, for example, the first signaling and the second signaling are SIB1, and the third signaling is PDCCH scheduling Msg2 or Msg 2; the third signaling may indicate the first resource to receive Msg2 and/or Msg4, and/or the first resource to send Msg 3. Or at least two of the first signaling, the second signaling, and the third signaling are different fields in the same signaling, for example, the first signaling and the second signaling are SIB1, and the third signaling is a PDCCH for scheduling Msg 4; the third signaling may indicate a first resource to receive Msg 4. This is not a limitation of the present application.

In addition, since the Msg4 is information dedicated to the terminal device, the network device sends Msg4 to each terminal device, and occupies a lot of resources, so that the network device indicates the resource or resource location for receiving Msg4 to the terminal device, and resource congestion can be avoided.

It should be understood that the candidate bandwidth has the same meaning as the candidate resource.

In one possible embodiment, the size of each candidate resource in the plurality of candidate resources is greater than or equal to the size of the first control resource, or the frequency range of each candidate resource in the plurality of candidate resources includes the frequency range of the first control resource, the plurality of candidate resources may be the initial DL BWP, and the first control resource may be CORESET0, as shown in (a) in fig. 6, the plurality of candidate resources may include the frequency range of the first control resource over the frequency range, or as shown in (b) in fig. 6, the plurality of candidate resources may include the frequency-corresponding location range of the first control resource in the frequency-corresponding location range. From the perspective of the network device, the network device may configure a plurality of candidate bandwidths for the first terminal device, and more resources may be used for downlink data transmission, thereby improving flexibility of resource allocation and avoiding resource congestion. From the perspective of the terminal device, the terminal device has a plurality of candidate bandwidths available for transmitting information, and the terminal device can determine the position of one of the first resources according to the rule, so that the flexibility of the terminal device in transmitting information is improved.

And after the first terminal equipment determines the position of the first resource, the downlink information is received through the first resource. The first control resource may be CORESET0 and the first resource may be an initial DL BWP.

In one possible embodiment, CORESET0 is contained in the initial DL BWP. When the RRC link of the UE is not established, the UE needs to receive within CORESET 0: a PDCCH for scheduling SIB1, a PDSCH for carrying SIB1, a PDCCH for scheduling SI, a PDSCH for carrying SI, a PDCCH for scheduling Msg2, a PDSCH for carrying Msg2, a PDCCH for scheduling Msg3, a PDCCH for scheduling Msg4, and a PDSCH for carrying Msg 4. Since many channels are transmitted in the CORESET0, the CORESET0 has a large resource occupation, which may result in limited allocation or congestion of the CORESET0 resource. Especially when the number of the UEs is large, the allocation limitation or the use congestion of the CORESET0 resource is further aggravated.

If the downstream data is not limited to be transmitted in the CORESET0 but transmitted in the initial DL BWP, more resources can be used for transmitting the downstream data, and thus the resource occupation of the CORESET0 can be reduced and the congestion can be reduced. From the network side, more resources can be used for downlink data transmission, thereby improving the flexibility of resource allocation. The downlink data can be one or more of system information, a random access response Msg2, a contention resolution message Msg4 and a paging message. For the control channel, the UE still performs reception of the control channel within CORESET 0.

It is to be understood that the downlink data may be received on the first resource, or the downlink control information may be received on the first resource, or both the downlink data and the downlink control information may be received on the first resource. The downlink control information may include one or more of control information for scheduling system information, a random access response message, a contention resolution message, and a paging message. The downlink data may include one or more of a PDSCH carrying system information block 1, a PDSCH carrying system information, a PDSCH carrying Msg2, and a PDSCH carrying Msg 4.

In one possible embodiment, when no RRC connection is established, downlink data and downlink control information are received in a first resource, where the first resource is an initial downlink BWP.

In another possible embodiment, the first resource has no overlapping resources with the first set of control resources.

In another possible embodiment, when no RRC connection is established, the downlink control information is received in a first set of control resources, and the data is received in a second bandwidth, where the RBs included in the second bandwidth are the RBs excluding the RBs included in the first set of control resources, as shown in fig. 7, that is, the first resource and the first set of control resources have an overlapping portion, and the data is received in a non-overlapping portion.

In another possible embodiment, when no RRC connection is established, the downlink control information is received in the first set of control resources and the data is received in the first resources or in the second bandwidth.

Illustratively, the information may be received within the first resource or the second bandwidth by pre-defining a threshold value of the bandwidth of the first resource or by transmission content.

In one possible embodiment, the downlink information is exemplified by data, and it can be determined that the data is received in the first resource or the second bandwidth by predefining a threshold value of the bandwidth of the first control resource set. Illustratively, when the bandwidth of the first control resource set is greater than or equal to a threshold value, the first terminal device receives data in the first resource; and when the bandwidth of the first control resource set is less than the threshold value, receiving data in the second bandwidth.

For example, the threshold value is 10MHz or the number of RBs corresponding to 10 MHz. When the bandwidth of the first control resource set is larger than or equal to the threshold value, the frequency range of the second bandwidth is smaller, and the resource allocation of the data is limited, so that the data is received in the first resource; when the bandwidth of the first set of control resources is less than the threshold, the frequency range of the second bandwidth is larger, and thus data is received within the second bandwidth.

And determining to receive the downlink information in the first resource or the second bandwidth through the transmission content. For example, the SIB1 and/or Msg2 are received within a first resource and the Msg4 is received within a second bandwidth. Because the Msg4 is information dedicated to the terminal device, the network device sends Msg4 to each terminal device, and occupies more resources, so that the network device sends Msg4 in the second bandwidth, and the first terminal device receives Msg4 in the second bandwidth, which can avoid resource congestion of the first control resource set.

Illustratively, the frequency range in which downlink information is received at the first resource or the first set of control resources may also be signaled. For example, the SIB1 indicates the resource range of transmission after the SIB1, or the downlink control information corresponding to the current transmission indicates the resource range of the current transmission.

In another possible implementation, the downlink data is received in the first resource, and the resource occupied by the downlink information in the frequency range of the first resource needs to be considered.

Taking the maximum channel bandwidth of the first terminal device as 20MHz, as shown in table 1 and table 2, the first row of the table is the subcarrier interval of CORESET0, the second row of the table is the bandwidth (RB number) of the first terminal device corresponding to the different subcarrier intervals and the number of bits required for allocating frequency resources, the third row of the table is the bandwidth (RB number) of CORESET0 and the number of bits specified in the existing protocol under the corresponding subcarrier interval, the fourth row of the table is the maximum number of bits additionally required in this embodiment, and the calculation method of the maximum number of bits additionally required may be the number of bits subtracted from the number of bits in the second row.

TABLE 1

TABLE 2

Illustratively, the available bits of the DCI in different scrambling modes are utilized to carry the bits that need to be added. The DCIs with different scrambling modes comprise: a P-RNTI scrambled DCI; SI-RNTI scrambled DCI; a RA-RNTI scrambled DCI; TC-RNTI scrambled DCI.

Available bit conditions of DCIs with different scrambling modes: DCI scrambled by P-RNTI has 6 idle bits; DCI scrambled by SI-RNTI has 15 bits available; the DCI scrambled by RA-RNTI has 16 bits available; the TC-RNTI scrambled DCI has 2 bits available.

The resources of the downlink data can be allocated by using the available bits of the DCI in different scrambling modes and the predefined resource allocation granularity.

Illustratively, the predefined resource allocation granularity may be N RBs, N being a positive integer. The predefined granularity of resource allocation may be determined according to the available bits and/or the number of bits that at most need to be added. For example, the resource allocation granularity corresponding to the number of bits 4 that need to be added at most may be 4 RBs.

The embodiment of the application can avoid frequent frequency tuning between uplink transmission and downlink reception and/or frequent frequency tuning between downlink reception and uplink transmission, increase available symbols for data transmission, improve resource utilization efficiency, reduce complexity of UE implementation, and reduce power consumption of UE. The network device can configure a plurality of DL/UL BWPs, each DL/UL BWP comprises CORESET0, and from the network side, more resources can be used for downlink/uplink transmission, thereby improving the flexibility of resource allocation.

In another embodiment of the present application, a method for transmitting information is provided, as shown in fig. 8

801: the first terminal equipment sends first uplink information in a first uplink bandwidth;

802: a first terminal device receives first downlink information in a first downlink bandwidth, and the sending of the first uplink information immediately precedes the receiving of the first downlink information; immediately prior means that there is no other uplink/downlink information between the first downlink information and the first uplink information.

The last time unit for sending the first uplink information is time unit n1, the starting time unit for monitoring the first downlink information is time unit m1, as shown in fig. 9, the minimum interval between time unit n1 and time unit m1 is k time units, where k is greater than w, w is the number of minimum time units between the last time unit n2 for sending the second uplink information and the starting time unit m2 for monitoring the second downlink information, and the sending of the second uplink information immediately precedes the receiving of the second downlink information, where m1, m2, n1, n2, k, and w are positive integers, the first terminal device is a first type terminal device, and the second terminal device is a second type terminal device.

The frequency range of the first uplink bandwidth and the frequency range of the first downlink bandwidth may correspond in frequency to a frequency range exceeding a maximum channel bandwidth of the UE.

It should be understood that the first terminal device may transmit uplink information through UL BWP and may receive downlink information through CORESET a, which may be CORESET0 for example.

It should be understood that the transmission of the first uplink information immediately prior to the reception of the first downlink information means: no other uplink information is transmitted or other downlink information is received between the transmission of the first uplink information and the reception of the first downlink information; the transmission of the second uplink information immediately prior to the reception of the second downlink information means that: there is no transmission of other uplink information between the reception of the second downlink information and the transmission of the second uplink information, and there is no reception of other downlink information.

The first downlink information is the first information interacted between the network equipment and the first terminal equipment after the first uplink information; similarly, the second uplink information is the first information interacted between the network device and the first terminal device after the second downlink information.

The last time unit refers to: the last time unit in the time units is occupied by the transmission of the uplink information or the last time unit in the time units occupied by the reception of the downlink information.

The starting time unit refers to: the first time unit in the time units occupied by the transmission of the uplink information or the first time unit in the time units occupied by the reception of the downlink information.

The first uplink bandwidth may be understood as UL BWP and the first downlink bandwidth may be understood as DL BWP. The positional relationship of the UL/DL BWP may be, for example: the UL BWP and DL BWP include CORESET0, i.e. the range of UL BWP in frequency domain completely covers the range of CORESET0 in frequency domain.

Specifically, after the first terminal device sends the uplink information in UL BWP, if the next transmission indicates that the first terminal device receives the downlink information in CORESET0, the first terminal device receives the downlink information in CORESET0 after at least a first time interval after the first terminal device sends the uplink information in UL BWP.

Wherein the frequency range of CORESET0 corresponds in frequency to the frequency range of UL BWP over the maximum channel bandwidth of the first terminal device.

Specifically, the time unit may be: subframe, radio frame, slot, mini-slot, symbol, microsecond, millisecond, second. For example, the time unit is a symbol, the time unit n is the last symbol n of the first uplink information, and the time unit m is the first symbol m of the first downlink information. For example, the minimum k time units may be k subframes, k radio frames, k slots, k mini slots, k symbols, k microseconds, k milliseconds, k seconds. For example, q time units may be q subframes, q radio frames, q slots, q mini-slots, q symbols, q microseconds, q milliseconds, q seconds.

For example, the first uplink information may be a random access sequence, and the first downlink information may be DCI scheduling a random access response. The last time unit for sending the random access sequence is time unit n1, that is, the last symbol of the random access occasion where the random access sequence is sent is time unit n 1. The starting time unit for monitoring the first downlink information is time unit m1, or the starting symbol position of DCI for monitoring the scheduling random access response is time unit m1, or the starting symbol position of RAR window configured by a higher layer is time unit m 1.

As shown in FIG. 10, there are a minimum of k time cells between time cell n1 and time cell m1, and k is greater than w.

It should be understood that the starting time unit for monitoring the first downlink information is a time unit for starting to detect the DCI scheduling the random access response, which may not have been successfully detected yet.

In one embodiment, w is 1 symbol and the time length of k time cells is greater than 1 symbol.

In one embodiment, k is 2 symbols added to w, i.e., k time units are 3 symbols. Or k is the corresponding time unit number of the first time interval in different subcarrier intervals added on the basis of w. For example, when the first time interval is 140 microseconds and the subcarrier interval is 15KHz, the number of symbols corresponding to 140 microseconds is 2 symbols; for example, when the subcarrier spacing is 30KHz, the number of symbols corresponding to 140 microseconds is 4 symbols. 2 symbols or a first time interval are used for the first terminal device to perform frequency modulation from a first uplink bandwidth to a first downlink bandwidth, wherein the frequency modulation refers to adjusting the working frequency of the first terminal device; 2 symbols or a first time interval can ensure that the first terminal equipment successfully receives the first downlink information in the first downlink bandwidth, and power loss caused by failure of receiving the first downlink information is avoided.

In one embodiment, k is the number of time units corresponding to the first time interval in different subcarrier intervals. For example, when the first time interval is 140 microseconds and the subcarrier interval is 15KHz, the number of symbols corresponding to 140 microseconds is 2 symbols; for example, when the subcarrier spacing is 30KHz, the number of symbols corresponding to 140 microseconds is 4 symbols. The first time interval is used for the first terminal device to frequency modulate from the first uplink bandwidth to the first downlink bandwidth, and the first time interval can ensure that the first terminal device successfully receives the first downlink information in the first downlink bandwidth, so that power loss caused by the failure of receiving the first downlink information is avoided.

In one embodiment, k is the number of time units corresponding to the first time interval, and q time units are included in the first time interval. For example, q time cells are 2 symbols, the first time interval is 210 microseconds, and 210 microseconds comprises q time cells.
