In order to cope with the future explosive mobile data traffic growth, equipment connection of mass mobile communication, various new services and application scenes which are continuously emerging, a fifth generation (the fifth generation, 5G) mobile communication system is generated. The international telecommunications union (international telecommunication union, ITU) defines three general classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (enhanced mobile broadband, emmbb), high reliability low latency communications (ultra reliable and low latency communications, URLLC), and mass machine type communications (massive machine type communications, mctc).

Currently, terminals performing services such as mctc are referred to as low complexity or low capability (reduced capability, redCap) terminals in the standard, and the bandwidth of low capability terminals is typically narrower, for example, the maximum channel bandwidth supported by low capability terminals in the FR1 band is 20MHz and the maximum channel bandwidth supported in the FR2 band is 100MHz. In addition, the low-capability terminal has lower power consumption and fewer antennas.

The services of the 5G and future mobile communication systems may include: eMBB, URLLC, mMTC, etc.
Typical eMBB services include, but are not limited to: ultra-high definition video, augmented reality (augmented reality, AR), virtual Reality (VR), and the like. The main characteristic of the eMBB service is that the transmission data volume is large and the transmission rate is high.
Typical URLLC traffic includes, but is not limited to: wireless control in industrial manufacturing or production processes, motion control of unmanned vehicles and unmanned aircraft, and haptic interactive applications such as remote repair and teleoperation. The URLLC service has the main characteristics of ultra-high reliability, low delay, small transmission data volume and burstiness of data transmission.
Typical mctc traffic includes, but is not limited to: smart grid distribution automation, smart cities, etc. The mMTC service is mainly characterized by large quantity of networking equipment, small quantity of transmission data and insensitivity of transmission delay. In general, mctc terminals are required to meet the demands of low cost and long standby time.
The requirements of different services on the mobile communication system are different, and how to better support the data transmission requirements of multiple services is a technical challenge faced by the current 5G mobile communication system. For example, how to support both mMTC service and eMBB service, or both URLLC service and eMBB service, has become a technical problem to be solved.
The 5G technology supports a large bandwidth, for example, an eMBB terminal may support a channel bandwidth of 100 MHz. In view of the requirements of energy saving and the like, a partial Bandwidth (BWP) is introduced in the 5G standard, and the network device may configure the BWP bandwidth for granularity with a Resource Block (RB). As a possible implementation, at most 4 BWPs specific to the terminal (UE specific) may be configured for the UE according to the capability of the terminal.
BWP, may also be referred to as carrier bandwidth part (carrier bandwidth part). In the frequency domain, one BWP includes a consecutive positive integer number of resource units, such as consecutive positive integer subcarriers, resource Blocks (RBs), or Resource Block Groups (RBGs). Wherein, one RB includes a positive integer number of subcarriers, for example, 12; one RBG includes a positive integer number of RBs, for example, 4 or 8 RBs, etc.
The BWP may be a downstream BWP or an upstream BWP. Wherein, the uplink BWP is used for the UE to send signals to the base station, and the downlink BWP is used for the base station to send signals to the UE. In the embodiment of the present application, the positive integer number may be 1, 2, 3 or more, and the present application is not limited thereto.
Fig. 1 illustrates, for example, BWP configured by a base station for a terminal.
2. Low-capability terminal
Low capability terminals may also be referred to as 5G lightweight (NRL) terminals, or low complexity terminal devices, or low cost terminal devices. The low-capability terminal is an R17 terminal, for example.
Because low-capability terminals may have a large number of connections and a large number of data to be transmitted, in some scenarios, congestion may be caused if there are a large number of low-capability terminals in the same area and a large number of low-capability terminals are accessed on the same BWP, such as the control resource set (CORESET # 0). For example, a low capability terminal affects a legacy terminal (legacy UE).
In some examples, legacy terminals may be non-low capability terminals or R15/16 terminal devices.
To avoid or reduce the impact of low capability terminals on legacy terminals, network devices, such as base stations, may configure a separate initial (separation initial) BWP for the low capability terminals. Wherein the independent initial BWP is distinguished from the BWP of the legacy terminal. Alternatively, the independent initial BWP is distinguished from the initial BWP configured in SIB 1. Examples of the initial BWP of the legacy terminal and the independent initial BWP of the low capability terminal are illustrated as examples in fig. 2A and 2B. In some aspects, as in fig. 2A, the initial BWP of the legacy terminal includes a bandwidth of CORESET #0, and CORESET #0 includes resources for receiving an update indication of system information. In some schemes, as shown in fig. 2B, the initial BWP of the legacy terminal includes resources (such as bandwidth) corresponding to the SSB, and the resources of the SSB are used for the terminal to receive the SSB.
By configuring the independent initial BWP for the low-capability terminal, the low-capability or partial low-capability terminal can be shunted to different frequency domain resources than the conventional terminal, thereby achieving the purpose of load balancing.
3. Packet data transmission (small data transmission, SDT)
In the R15 standard, a terminal in an inactive state (or called idle state, non-connected state, inactive) needs to enter a connected state (or called active state, non-idle state, etc.) through a connection recovery procedure, and performs service transmission in the connected state. After transmitting the traffic, the terminal may return to the inactive state.
The R17 standard introduces the SDT in the inactive state, so that the terminal can transmit the SDT service without entering the connected state. In the SDT transmission scheme, the terminal does not need to switch between different states, and the high power consumption expense can be avoided. The SDT service transmission in the inactive state may be any of the following modes:
in mode 1, in the inactive state, the low-capability terminal carries the SDT service through the random access message. The terminal carries the SDT service in message 3 of the 4-step random access procedure, for example. For another example, the terminal carries SDT service in message a (MSGA) of the 2-step random access procedure.
And if the terminal has uplink or downlink data, the terminal can still be kept in an inactive state after the random access contention is solved, and the subsequent uplink or downlink data transmission is carried out in a network dynamic scheduling mode. After the data is sent, the terminal can be released quickly.
In the mode 2, in the inactive state, if Timing Advance (TA) is valid, the terminal may directly transmit the SDT service on a Configured Grant (CG) resource, without entering the active state. The validity of the TA may be determined by the measurement of the synchronization signal block (synchronization signal block, SSB) by the terminal.
Alternatively, the timing advance may also be referred to as timing adjustment (timing adjustment). The embodiment of the application does not limit the specific name of the TA.
In addition, in the CG-SDT process, the network can also transmit uplink and downlink data in a dynamic Dispatch (DG) mode.
Currently, resources for transmitting SDT traffic may be configured within the independent initial BWP, i.e., the independent initial BWP includes resources for transmitting SDT traffic.
4. Cell defined SSB (cell defined SSB, CD-SSB)
Currently, in the non-connected state, the low capability terminal receives paging messages on a CD-SSB related BWP. If the independent initial BWP of the low capability terminal is used for Random Access (RACH) and is not used for paging, SSB/CORESET #0/SIB may not be included in the independent initial BWP.
5. Non-cell defined SSB (NCD-SSB)
The terminal supports NCD-SSB based measurements (e.g., mobility measurements (radio resource management, RRM)) to guarantee the performance of the transmission. The difference between NCD-SSB and CD-SSB is that CD-SSB may also indicate transmission of System Information Blocks (SIBs) whereas NCD-SSB is used for measurements and does not need to indicate system information blocks.
It can be seen that, for the low-capability terminal, due to its narrower bandwidth, in some scenarios, as shown in fig. 2A and fig. 2B, the independent initial BWP of the low-capability terminal does not cover the bandwidth corresponding to SSB and/or coreset#0, so that the low-capability terminal cannot perform some functions, and the communication performance of the low-capability terminal is poor. For example, the low-capability terminal cannot measure SSB on the independent initial BWP, so that the low-capability terminal cannot synchronize with the network device, which affects the subsequent communication performance of the low-capability terminal.
In order to solve the above technical problems, an embodiment of the present application provides an information transmission method. Fig. 3 is a schematic diagram of a communication system to which an embodiment of the present application is applied. The communication system includes a network device, and one or more terminals (e.g., terminals 1 through 6 in fig. 3) in communication with the network device.

The embodiment of the application does not limit the deployment and application scenes of the network equipment and the terminal equipment.

For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a network device. For D2D signal transmission, the transmitting device is a terminal device and the corresponding receiving device is a terminal device.

The information transmission method provided by the embodiment of the application is described below with reference to the accompanying drawings.
Example 1
Referring to fig. 5, the information transmission method provided by the embodiment of the application includes the following steps:
s101, in a first time period, the network equipment sends the SSB on a resource corresponding to the SSB and/or sends an update instruction of system information on a resource corresponding to CORESET#0.
Correspondingly, in the first period, the terminal equipment receives the SSB on the resource corresponding to the SSB and/or receives the update indication of the system information on the resource corresponding to CORESET#0. Wherein the update indication is used for indicating whether the system information is updated.
Wherein the terminal may be a low capability terminal, or a terminal with similar characteristics.
For example, the resource may be at least one of: frequency domain resources, time domain resources, bandwidth, resource blocks, BWP, control resource sets, subbands.
Alternatively, the first period of time may also be referred to as one or more of an interval (GAP), an interruption period of time, a measurement window, a receiving window.
The terminal receiving the SSB in the first period of time may refer to the terminal receiving the SSB in the first period of time and determining the validity of the TA according to the SSB. The first time period includes a time for the terminal to process the SSB. In some schemes, the validity of the TA may be used to determine the quality of synchronization between the terminal and the network device, thereby improving the reliability of the transmission.
The terminal receiving the update indication in the first period of time may refer to the terminal receiving the update indication and processing the update indication in the first period of time. In some schemes, in the first period, if the update indication received by the terminal indicates that the system information is updated, the terminal monitors the updated system information. If the update indication received by the terminal indicates that the system information has not been updated during the first period of time, the terminal does not need to monitor the system information for a short period of time, and in some examples, the terminal may switch to the first BWP (independent initial BWP) for SDT service transmission.
Optionally, the resources corresponding to SSB and the first BWP (e.g., the independent initial BWP) do not overlap in the frequency domain. Alternatively, the resource corresponding to CORESET #0 does not overlap with the first BWP in the frequency domain. The frequency domain resource corresponding to SSB, CORESET #0, may be referred to as a frequency domain resource outside the first BWP bandwidth.
Illustratively, as in FIG. 2A, the resources corresponding to CORESET#0 do not overlap with the independent initial BWP. Still further exemplary, as in fig. 2a, the ssb corresponding resources do not overlap with the independent initial BWP.
As a possible implementation, the terminal device does not transmit SDT service during the first period of time. For example, in the first period, the terminal device is not required to transmit and receive information in the first BWP.
Optionally, the system information includes, but is not limited to, any one or more of the following: paging message (paging), downlink control information (downlink control information, DCI) for scheduling paging messages, public warning system (public warning system, PWS) message, system information block, DCI for scheduling system information block, system information block 6 (system information block, SIB 6), system information block 7 (SIB 7), system information block 8 (SIB 8), information in CORESET # 0.
As one possible implementation, the network device sends the system information periodically. For example, the system information is transmitted every 10 ms.
As one possible implementation, the network device updates the system information according to a period, which may be referred to as an update period of the system information. For example, the system information is updated every 10000 ms.
Alternatively, the DCI may be scrambled by a radio network temporary identity (radio network tempory identity, RNTI) for scrambling system information, such as an S-RNTI, or by a radio network temporary identity (P-RNTI) for scrambling paging messages, or there are other scrambling means.
Correspondingly, the update indication of the system information includes: update indication of system information block, update indication of paging message, update indication of PWS, paging message (paging), DCI for scheduling paging message, information in CORESET#0.
The above lists several examples of the system information, and the system information may also be other information, for example, other information that can be received by the terminal device in a non-connected state, and by using the received system information, the communication performance of the terminal device can be improved. Accordingly, the update indication may be other indication information.
For example, if a paging resource is included in the BWP, the update indication may be an update indication received during SDT transmission.
Illustratively, the system information is transmitted in a first DCI. Optionally, the format of the first DCI is format 1_0.
For example, the first DCI may be a DCI scrambled by a TC-RNTI, or by a RA-RNTI, or by an MsgB-RNTI, or by a C-RNTI.
Illustratively, the TC-RNTI scrambled first DCI includes a "Downlink assignment index" field including 2 bits, reserved for bits. Legacy terminals typically do not read the information of this field or consider the information of this field invalid. Similarly, there are reserved bits in the first DCI scrambled by RA-RNTI. An update indication carrying or representing system information with a reserved field in the first DCI may be considered.
For example, for a low capability terminal, the first DCI scrambled by the TC-RNTI does not include a "Downlink assignment index" field but includes a "system information update" field. For legacy terminals, the first DCI scrambled by the TC-RNTI includes a "Downlink assignment index" field and does not include a "system information update" field. The aforementioned "Downlink assignment index" field and the "new of system information" field have the same bit positions in the first DCI. For example, the same bit position may be understood as the 10 th and 11 th bits in the first DCI.
For example, for a low capability terminal, the number of bits of the reserved field included in the first DCI is a-B (a minus B), and the reserved field is a "system information update" field. For the legacy terminal, the number of bits of the reserved field included in the first DCI is a, and the field is not used as a "system information update" field. Wherein A is an integer, and B is an integer. E.g., a=16, b=2. For example, the number of bits of the system information update field is 1 or 2.
For example, the "system information update" field may be used to indicate whether the terminal enters the connected state, in addition to indicating whether the system information is updated.
Optionally, the first signal comprises any one or more of the following: SSB, synchronization signal/physical broadcast channel block (synchronization signal/physical broadcast channel block, SS/PBCH block), cell defined SSB (CD-SSB), non-cell defined SSB (NCD-SSB), channel state information reference signal (channel state information-reference signal, CSI-RS), tracking reference signal (tracking refernece signal, TRS), phase tracking reference signal (phase tracking reference signal, PTRS), demodulation reference signal (demodulation reference signal, DMRS). The first signal is used to determine a signal of TA validity.
For example, the first signal is a signal used in the SDT process to determine the validity of the TA.
As one possible implementation, the network device may configure the terminal with resources corresponding to SSB and coreset#0.
As a possible implementation manner, as shown in fig. 6A, S101 may be implemented as follows: and S101a, in a first time period, the network equipment transmits the SSB on the resources corresponding to the synchronous signal block SSB. Illustratively, as shown in fig. 7A, during a first period of time (e.g., GAP 1), the network device transmits the SSB, and, correspondingly, during the first period of time, the terminal device receives the SSB. Optionally, in the first period, the terminal device receives the SSB, which may be implemented as: during a first period of time, the terminal device receives and processes the SSB (e.g., determines the validity of the TA based on the SSB).
Alternatively, as shown in fig. 7B, the network device sends the SSB in the first period of time, which may be implemented as: during a first time period, the network device transmits the SSB over a bandwidth of the SSB. Accordingly, the terminal device receives the SSB in the first period of time, which may be implemented as: in a first period of time, the terminal device receives the SSB over a bandwidth of the SSB.
As a possible implementation manner, as shown in fig. 6B, S101 may be implemented as follows: s101b, in the first time period, the network equipment sends an update instruction of the system information on the resource corresponding to the control resource set CORESET#0. Illustratively, as shown in fig. 8A, during a first period of time (such as GAP 2), the network device sends an update indication of the system information, and, correspondingly, during the first period of time, the terminal device receives the update indication. Alternatively, as shown in fig. 8B, the network device sends the update indication in the first period of time, which may be implemented as: during a first period of time, the network device transmits an update indication over the bandwidth of CORESET # 0.
As a possible implementation manner, as shown in fig. 6C, S101 may be implemented as follows: s101c, in the first period, the network device sends the SSB on the resource corresponding to the synchronization signal block SSB, and sends the update instruction of the system information on the resource corresponding to the control resource set coreset#0. Illustratively, as shown in fig. 9A, during a first period of time (such as GAP 3), the network device sends an update indication of system information and SSB, and, correspondingly, during the first period of time, the terminal device receives the update indication and SSB. Alternatively, as shown in fig. 9B, the network device sends the update indication in the first period of time, which may be implemented as: during a first period of time, the network device transmits an update indication over the bandwidth of CORESET # 0. The network device sending SSBs during the first period of time may be implemented as: during a first time period, the network device transmits the SSB over a bandwidth of the SSB.
In the scheme, because the network equipment and the terminal equipment can determine the first time period, the network equipment and the terminal equipment can interact SSB and/or update the indication in the first time period, which is beneficial to improving the interaction success rate of the SSB and/or update the indication, and further improving the communication performance of the terminal equipment in the subsequent communication process. For example, since the terminal device knows that the SSB and/or the update indication should be monitored in the first period, the terminal only monitors the SSB and/or the update indication when the first period is reached, but does not monitor in other periods, so that the success rate of monitoring can be ensured, and the problem that the communication performance of the terminal device is poor (for example, the validity of the TA cannot be verified, and thus the terminal device cannot synchronize with the network device, or the PWS cannot be successfully received) caused by missing the monitoring time can be avoided.
And S102, the terminal equipment transmits the SDT service on the first BWP in the second time period.
Wherein the second time period does not overlap with the first time period. The first BWP does not include the resources of the SSB and/or the resources of the CORESET # 0.
Optionally, the first BWP comprises an independent initial downstream BWP or an independent initial upstream BWP. For example, the first BWP is an initial upstream BWP or an initial downstream BWP.
The SDT service may be referred to as a first service, which is a data transmission service in a non-connection state. As technology evolves, the first service may also be replaced with other similar services.
Illustratively, and as also shown in fig. 7A, SDT traffic is transmitted between the network device and the terminal device during a second time period. Alternatively, as shown in fig. 7B, during the second period, the SDT service is transmitted between the network device and the terminal device, which may be implemented as: and in the second time period, the SDT service is transmitted on the independent initial BWP between the network equipment and the terminal equipment.
It should be noted that, taking the example of receiving the update indication, in the first period, the terminal device receives the update indication on coreset#0. For example, after a first period of time, the terminal device transmits SDT traffic on the first BWP. For example, before the first period of time, the terminal device transmits SDT traffic on the first BWP. In this way, the network device and the terminal device perform information transmission in the same BWP in the same time period, and information transmission failure caused by inconsistent understanding is avoided. Or, the terminal device may also receive the update indication during the SDT service transmission process.
The first BWP does not include the resources of the SSB and/or the resources of the coreset#0, and may be that the first BWP does not overlap with the resources of the SSB; alternatively, the first BWP does not overlap with the resources of CORESET#0; alternatively, the resources of the first BWP and SSB do not overlap, and the resources of the first BWP and CORESET#0 do not overlap. Alternatively, the resources do not overlap, which may mean that the resources in the frequency domain do not overlap. Alternatively, the resources do not overlap, which may mean that the resources in the frequency domain do not partially overlap. For example, the first BWP does not entirely include SSB. For example, the first BWP does not entirely include CORESET #0.
In some embodiments, the configuration parameters of the first period are predefined, in other words, the terminal may determine the configuration parameters of the first period according to predefined information. This approach may save signaling overhead.
Or, the configuration parameters of the first time period are determined according to preset rules. In other words, the terminal may determine the configuration parameter of the first period according to a preset rule. The configuration parameters of the first time period are determined according to the preset rules, so that the method has certain flexibility and low signaling overhead.
Alternatively, the configuration parameters of the first period are configured by the network device, in other words, the terminal may determine the configuration parameters of the first period according to the signaling from the network device. The configuration parameters of the first period are configured by the network device, and may be implemented as: the configuration parameters of the first time period are configured by radio resource control (radio resource control, RRC) signaling or DCI or system information. The method can flexibly configure the configuration parameters of the first time period and meet the dynamic scheduling of the network.
Optionally, the configuration parameters of the first period include: at least two of a start time, a length, an end time, and a period. The terminal device may determine at least two of the configuration parameters of the first time period and determine the first time period according to the at least two configuration parameters. The configuration parameters of the first time period may also include other parameters as long as they can be used to determine a specific time domain position of the first time period.
Optionally, the starting time of the first period of time includes at least one of: a start time slot, a start symbol, a start frame, and a start subframe. Optionally, the end time of the first time period includes at least one of: end slot, end symbol, end frame, end subframe. Optionally, the length of the first time period includes at least one of: the number of time units occupied by the first time period, the number of symbols occupied, the number of slots occupied, the number of frames occupied, the number of subframes occupied. The configuration parameters may also be in other forms, and embodiments of the present application are not limited in this regard.
Optionally, the starting time of the first period is determined according to any one or more of the following information:
the update indication is located in a time unit, the update indication is located in a starting time of a radio frame, the SSB is located in a time unit, the SSB is located in a starting time of the radio frame, and radio frequency tuning (radio frequecy retuning) time.
The radio frequency tuning time may be a time when the terminal switches from the first frequency band to the second frequency band. The radio frequency tuning time may be determined based on the capabilities of the terminal. In some examples, the terminal may report capability information to a network device, which may determine a radio frequency tuning time of the terminal based on the capability information of the terminal.
In the embodiment of the present application, the time unit may be a time slot, a symbol, a subframe, a frame, a microsecond, a millisecond, or a second, or other time units.
For example, as shown in fig. 10, the radio frame in which the update indication is located is shown, where the black filling indicates the time slot in which the update indication is located (time slot B, C, D, E), and the starting time of the radio frame may be the starting time slot of the radio frame (i.e., instant a). The starting time of the first time period for transmitting the update indication, such as the starting time slot, may be determined from time slot B, C, D, E. For example, the starting time of the first period is time slot B. Alternatively, the starting instant of the first time period may be determined from time slot a. For example, as shown in fig. 10, the starting time of the first period is the time slot a. The terminal may receive the update indication within a first time period, such as the terminal may receive and process the update indication within the first time period.
As another example, fig. 11 shows a radio frame in which the SSB is located, where black padding indicates a time slot (time slots B1, C1, D1) in which the SSB is located, and the starting time of the radio frame may be the starting time slot (i.e., time slot A1) of the radio frame. The starting instant of the first time period for receiving SSB may be determined from the time slots B1, C1, D1. Alternatively, the starting time of the first time period may be determined from the time slot A1. The terminal may receive the SSB in a first period of time, e.g., the terminal may receive the SSB in the first period of time and determine the validity of the TA based on the SSB.
In some examples, considering that a certain time is required for the terminal to switch the frequency band, that is, a certain time is required for the terminal to switch from working in the first frequency band to working in the second frequency band, in the embodiment of the present application, the terminal may switch to the bandwidth corresponding to SSB or the bandwidth corresponding to coreset#0 in advance according to the tuning time.
For example, as shown in fig. 12, assuming that the tuning time is T1, and the update indicates that the first slot of the radio frame is slot a, the low capability terminal may determine the starting time of the first period according to slot a and the tuning time T1. For example, as shown in fig. 12, the first period starts at a time T1, and T1 is a time interval T1 before the time slot a. In T1 of the first period, the low-capability terminal is first switched from the first BWP (e.g., independent initialization) to the bandwidth of coreset#0, and then receives an update indication of the system information on the bandwidth of coreset#0.
As another example, as shown in fig. 13, assuming that the tuning time is T1 and the first slot of the radio frame in which the update instruction is located is slot a, the low capability terminal may determine the starting time of the first period according to slot B, C, D (i.e., the slot in which the update instruction is located) and the tuning time T1. For example, as shown in fig. 13, the first period starts at a time T1', T1' being a time interval T1 before the time slot B. In T1 of the first period, the low-capability terminal is first switched from the first BWP (e.g., independent initialization) to the bandwidth of coreset#0, and then receives an update indication of the system information on the bandwidth of coreset#0.
Similarly, the low-capability terminal may determine the starting time of the first period according to the time unit in which the SSB is located and the tuning time. Alternatively, the low-capability terminal may determine the starting time of the first period according to the starting time of the radio frame in which the SSB is located and the tuning time.
It should be noted that, the starting time of the first period may also be determined according to other information. For example, an L (positive integer) th paging opportunity (paging opportunity, PO) within each paging cycle (paging cycle) may be predefined as a starting moment of the first period. Wherein the paging opportunity may be used to transmit a paging message.
Optionally, the length of the first period of time is related to a first parameter. The first parameter should be related to the time of receiving and processing the relevant signals, considering that the first time period is used for receiving SSBs and/or for receiving update indications. The correlation signal is a signal indicating that SSB and/or update is correlated.
Optionally, the first parameter includes any one or more of: radio frequency tuning time, duration of the SSB (duration of a time unit in which the SSB is located), duration of detecting the SSB, duration of a downlink signal, duration of processing the downlink signal, duration of the update indication, duration of processing the update indication, duration of the system information, duration of processing the system information, whether the system information is updated, update time of the system information, update period of the system information, paging period, duration of a paging opportunity, and time domain resources of available paging opportunities corresponding to the SSB.
Optionally, the downstream signals include, but are not limited to, any one or more of the following: signals transmitted on a physical downlink control channel (physical downlink control channel, PDCCH), signals transmitted on a physical downlink shared channel (physical downlink shared channel, PDSCH).
Optionally, detecting the duration of the SSB, which may also be referred to as processing the SSB, includes determining the duration of TA validity based on the SSB.
Illustratively, when the first time period is for receiving the SSB, the first time period includes a duration of the SSB. For example, as in fig. 11, the length of the first period may be the total duration of the time slots B1, C1, D1.
Still further exemplary, when the first time period is used to receive the SSB, the first time period includes a duration of the SSB (e.g., T2) and a duration of determining the TA validity based on the SSB (e.g., T3).
Further exemplary, the length of the first time period may be flexibly adjusted. Optionally, the length of the first period of time is related to whether the system information is updated. Illustratively, as in (a) of fig. 16, it is assumed that the initial first period of time is GAP4. In the first time period, the terminal receives the update indication on CORESET #0, and if the update indication indicates that the system information is not updated, the terminal does not need to monitor the system information in a short time. As one possible implementation, the terminal may switch to the first BWP (e.g., the independent initial BWP) after the first period of time in order to transmit the SDT service on the first BWP.
Still further exemplary, the length of the first period of time is a fixed value. For example, the first time period is a time units, and a is a positive integer. For another example, the first time period is 1 slot or 2 slots. For another example, the first time period is 20 symbols. For another example, the first time period is 1000 microseconds or 2000 microseconds. For another example, the first time period is 1.5 milliseconds.
Still further exemplary, as in fig. 14, the first time period includes x time units (duration T1) before SSB. Optionally, the x time units are determined based on the radio frequency tuning time. For example, x time units are 140 μs, or 280 μs, or 70 μs, or 560 μs.
Still further exemplary, as shown in fig. 15, the first time period includes x time units (duration T1) before the paging opportunity. The terminal may receive an update indication within a first period of time. The terminal may receive paging messages within the pager.
Still further exemplary, as in fig. 16 (a), assume that the initial first period of time is GAP4. In GAP4, the terminal receives an update indication on coreset#0, and if the update indication indicates that the system information has an update, the terminal needs to monitor the system information. In one example, the terminal may extend the first period of time assuming that no updated system information is transmitted within the initial first period of time GAP4. For example, the first period of time may be extended from GAP4 to GAP5 as shown in fig. 16 (b). In GAP5, the terminal listens for updated system information. Thereafter, after GAP5, the terminal may switch to the first BWP (e.g., an independent initial BWP) in order to transmit SDT traffic on the first BWP.
Further exemplary, as shown in fig. 17A, after the system information is updated, the network device sends an update indication during the current update period (e.g., update period a). The network device may send system information a during update period a. As one possible implementation, the network device may send the system information a multiple times within the update period a.
The updated system information B is transmitted in the next update period B (the start time of the update period is assumed to be t 2). Alternatively, the network device may send the system information B multiple times within the update period B.
Optionally, after receiving the update indication on coreset#0, the terminal switches back to the first BWP (related to the length of the first period of time) in relation to the time interval of the current moment distance t 2. For example, if the current time (such as t3 shown in fig. 17A) is closer to t2, the terminal does not switch back to the first BWP, but continues to monitor the system information at coreset#0, so as not to switch from the first BWP to coreset#0 again to monitor the updated system information B after the terminal switches back to the first BWP. Accordingly, as shown in fig. 17A, the first period may be extended until the terminal receives the updated system information B.
For another example, if the current time (e.g., t3 shown in fig. 17B) is far from t2, the terminal may switch back to the first BWP. After that, after the second period, the terminal switches from the first BWP to CORESET #0 to listen for updated system information B.
Still further exemplary, taking system information as a paging message, as in fig. 18, the length of the first period of time is related to the duration of the paging opportunity. The network device sends a paging message at a paging opportunity and the terminal device listens for and processes the paging message for a first period of time (e.g., a length greater than or equal to the paging opportunity or the duration of the paging message).
For example, y time units after the last symbol of the system information. For example, y time units are determined based on the first parameter.
Illustratively, the y time units are determined according to the radio frequency tuning time and the duration of PDSCH processing by the terminal device. For example, y time units are the sum of tuning time and the duration of PDSCH processing by the terminal device.
Further exemplary, y time units are determined based on whether there is an update to the system information. For example, the system information is updated and y time units are determined according to the tuning time and the duration of the processing of the signal (/ information) carrying the system information update indication by the terminal device. The terminal device tunes back to the first BWP after receiving the system information update indication. For another example, the system information is not updated, and y time units are determined according to the tuning time, the duration of processing of the signal (/ information) carrying the system information update instruction by the terminal device, the transmission time of the system information, and the time of processing the system information by the terminal device. For another example, the system information is updated, and y time units are determined according to the tuning time, the duration of processing the signal (/ information) carrying the system information update instruction by the terminal device, the sending time of the system information, and the time of processing the system information by the terminal device. For example, the time at which the updated system information is transmitted and the transmission time interval of the system information update indication are greater than or equal to the first threshold, and the terminal device tunes back to the first BWP after receiving the system information update indication. For example, the transmission time of the updated system information and the transmission time interval of the system information update indication are less than or equal to a first threshold, and the terminal device receives the system information at the first opportunity in the next system information update period. For example, the network device configures the time or time period for which the terminal device receives the system information update indication.
Optionally, the period of the first period of time is determined according to any of the following information: paging cycle (paging cycle), discontinuous reception (discontinuous reception, DRX) cycle (period), extended discontinuous reception (extended discontinuous reception, eDRX) cycle, update cycle of system information, extended discontinuous reception acquisition (extended discontinuous reception acquisition, eDRX acquisition) cycle.
Illustratively, as shown in fig. 18, the mth (positive integer) time slot to the nth (positive integer) time slot of each paging cycle is the first time period. For example, the terminal transmits SDT traffic on a first BWP (independent initial BWP), and when the start time of the first period of paging cycle a arrives, the terminal switches to receiving SSB on the bandwidth corresponding to SSB. After the first period of time, the terminal may switch again to the first BWP in order to transmit the SDT service. And when the starting moment of the first time period of the paging cycle B arrives, the terminal is switched to the bandwidth corresponding to the SSB to receive the SSB. After the first period of time, the terminal may switch again to the first BWP.
It should be noted that other configurations of the first period are also possible. For example, as shown in fig. 19, assuming that the time n is the starting time of uplink transmission, or is the starting time of uplink transmission resources, or is the starting time of pre-Configured (CG) resources, and in the [ n-m-L, n-m ] time window, the terminal is allowed to interrupt SDT service transmission, or the terminal does not expect the network device to send a downlink signal (such as SDT service), or the network device does not schedule the terminal device to send an uplink signal, or the terminal device does not need to transmit a service such as SDT, or does not require the terminal device to transmit a service such as SDT, then the first time period may be the time window [ n-m-L, n-m ]. As in fig. 19, the terminal may receive the SSB and/or the update indication within a first period of time and send SDT traffic on the uplink time domain resources.
Wherein m and n are integers greater than or equal to 0.
Before the first period of time, the method further comprises:
and in the third time period, the terminal equipment transmits the SDT service. Illustratively, as shown in fig. 8A, during a third period of time, the terminal device transmits SDT traffic on the first BWP, after which the first period of time arrives, and the terminal device switches to receiving the update indication on a corresponding resource outside the first BWP. The terminal device then switches back to the first BWP in order to transmit the SDT service. It can be seen that, during SDT service transmission, the terminal device may suspend SDT service transmission during the first period of time, so as to monitor the corresponding message (SSB and/or update indication) during the first period of time, and thus, can improve the communication performance of the terminal device by monitoring the corresponding message.
Example two
The embodiment of the application also provides an information transmission method, which can configure resources for receiving the NCD-SSB and/or resources for receiving the update indication in the first BWP for the low-capability terminal, so that the low-capability terminal can transmit SDT service on the first BWP and receive the NCD-SSB. Alternatively, the low capability terminal may transmit SDT traffic on the first BWP and receive the update indication. Alternatively, the low capability terminal may transmit SDT traffic on the first BWP and receive the NCD-SSB and the update indication.
As shown in fig. 20, the method comprises the steps of:
s201, the network device sends a second signal on the first BWP and/or sends an update indication of the system information on the first BWP, where the update indication is used to indicate whether the system information is updated.
Accordingly, the terminal receives the second signal on the first BWP and/or receives an update indication of the system information on said first BWP.
Wherein the second signal includes, but is not limited to, NCD-SSB. The second signal may be used to determine TA validity. The following description will mainly be given by way of example of NCD-SSB, but this does not constitute a limitation on the second signal, which may also be other signals for determining the validity of TA.
The first BWP (independent initial BWP) does not comprise a CD-SSB and/or the control resource set CORESET #0, and comprises resources corresponding to the NCD-SSB and/or resources corresponding to the update indication.
The first BWP does not include the CD-SSB and may be understood as not including the complete CD-SSB.
The first BWP does not include CORESET #0 and may be understood to not include complete CORESET #0. For example, for frequency band FR1, the first BWP does not include CD-SSB and/or coreset#0 may be understood to include CD-SSB and coreset#0, or CD-SSB, or coreset#0. For example, for frequency band FR1, the first BWP may be understood to exclude CD-SSB and/or CORESET #0.
In the embodiment of the present application, for a low-capability terminal, if a resource for transmitting SDT service is configured in the first BWP, the terminal expects that the first BWP includes a resource corresponding to NCD-SSB and/or a resource corresponding to update indication. E.g., the resource to which the first signal corresponds) and/or update indicates the corresponding resource. For the network device, if resources for transmitting SDT traffic are configured in the first BWP, the network device should configure resources corresponding to the NCD-SSB and/or update the resources corresponding to the indication within the first BWP. For example, for the frequency band FR1, if resources for transmitting SDT traffic are configured in the first BWP, which does not include the CD-SSB and the complete CORESET #0, the terminal expects resources including the first signal within the first BWP. For example, for the FR1 band, if resources for transmitting SDT traffic are configured in the first BWP, the first BWP does not include the CD-SSB and the full CORESET #0, the terminal is not required to receive the update indication or is not required to receive the paging message. For example, for the frequency band FR2, if resources for transmitting SDT traffic are configured in the first BWP, which does not include the CD-SSB, the terminal expects resources including the first signal within the first BWP. For example, for frequency band FR2, if the resources for transmitting SDT traffic are configured in the first BWP, the first BWP does not include the CD-SSB, the terminal is not required to receive the update indication or is not required to receive the paging message.
Optionally, the configuration information of the first signal is received by the terminal device before entering the non-connected state, or received in the connected state. For example, the configuration information of the first signal includes at least one of: configuration information of frequency domain resources of the first signal, configuration information of periods of the first signal, configuration information of time domain resources of the first signal, and configuration information of power of the first signal.
Optionally, the first BWP includes a resource corresponding to the NCD-SSB and/or a resource corresponding to the update indication, which may be implemented as:
the first BWP includes a resource corresponding to the update indication, or the first BWP includes a resource corresponding to the NCD-SSB and a resource corresponding to the update indication, or the first BWP includes a resource corresponding to the NCD-SSB.
Illustratively, as shown in fig. 21A, the first BWP (independent initial BWP) does not include the CD-SSB, and the first BWP includes resources corresponding to the NCD-SSB (such as the bandwidth of the NCD-SSB). Accordingly, as shown in fig. 21B, step S201 may be implemented as: s201a, receiving the NCD-SSB on the first partial bandwidth BWP.
Alternatively, as shown in fig. 22A, the first BWP (independent initial BWP) does not include the CD-SSB, and the first BWP includes the resources (such as bandwidth) corresponding to the update indication. As shown in fig. 22B, the update indication receiving procedure under the resource configuration, step S201 may be implemented as: s201b, receiving an update indication on the first partial bandwidth BWP.
Alternatively, as shown in fig. 23A, the first BWP (independent initial BWP) does not include the CD-SSB, and the first BWP (independent initial BWP) includes the resources of the NCD-SSB and the resources corresponding to the update indication. As shown in fig. 23B, the update instruction receiving flow under the resource configuration, step S201 may be implemented as: s201c, receiving the NCD-SSB and the update indication on the first partial bandwidth BWP.
Still further exemplary, the first BWP (independent initial BWP) does not include CORESET#0, and the first BWP includes resources corresponding to NCD-SSB (such as the bandwidth of NCD-SSB). Alternatively, the first BWP includes resources of the NCD-SSB and the update indicates the corresponding resources. Alternatively, the first BWP includes a resource corresponding to the update indication.
Still further exemplary, the first BWP (independent initial BWP) does not include CORESET#0 and CD-SSB, and the first BWP includes resources corresponding to NCD-SSB (such as bandwidth of NCD-SSB). Alternatively, the first BWP includes resources of the NCD-SSB and the update indicates the corresponding resources. Alternatively, the first BWP includes a resource corresponding to the update indication.
Optionally, the update indication is transmitted in a first DCI (refer to the description of embodiment one). Optionally, the update indication is transmitted through RRC signaling.
Optionally, the configuration parameter of the resource corresponding to the NCD-SSB and/or the configuration parameter of the resource corresponding to the update indication are configured by the network device.
Optionally, the configuration parameters of the resources corresponding to the NCD-SSB are configured by the network device, including: and the configuration parameters of the resources corresponding to the NCD-SSB are carried in RRC signaling or broadcast signaling.
As a possible implementation, the terminal device receives the signaling from the network device before entering the non-connected state or in the connected state, and determines the resource configuration information of the NCD-SSB and/or updates the indicated resource configuration information according to the signaling.
Optionally, the updating indicates that the configuration parameter of the corresponding resource is configured by the network device, including: the update indicates that the configuration parameters of the corresponding resources are carried in the RRC signaling, or the downlink control channel, or the broadcast signaling.
And S202, the terminal equipment transmits the packet data transmission SDT service on the first BWP.
It can be seen that, in the case that the first BWP includes both the resources for transmitting the SDT service and the resources corresponding to the update indication (and/or the resources corresponding to the NCD-SSB), when the terminal device needs to monitor the NCD-SSB, the terminal device does not need to tune to the resources where the NCD-SSB is located by the current resource, which avoids transmission interruption and influence on the service rate caused by the reciprocal switching of the terminal device, and can improve the communication performance of the terminal device.
In other embodiments, when the terminal supports the transmission of SDT traffic in the first BWP, the terminal expects to include resources for receiving the second signal and/or resources for receiving the update indication in the first BWP. In this manner, the first BWP may include CD-SSB and/or CORESET#0. Alternatively, CD-SSB and/or CORESET#0 may not be included in the first BWP.
It should be noted that, in the present application, the steps are not sequential, as in the second embodiment, S202 may be earlier, and S202 may be later.
Example III
The embodiment of the application also provides an information transmission method, which can configure the priority of SDT service, SSB and update instruction, and discard the information with low priority when a plurality of pieces of information collide, so as to improve the reliability of the information with high priority.
As a possible implementation, the SDT service has a higher priority than the update indication, and/or the SDT service has a higher priority than the SSB.
If the third time-frequency resource and the fourth time-frequency resource are overlapped (overlap), or if the interval between the third time-frequency resource and the fourth time-frequency resource in the time domain is smaller than a threshold, transmitting the SDT service; the third time-frequency resource is used for transmitting SDT service, the fourth time-frequency resource is used for transmitting the SSB and/or the update indication, and the third time-frequency resource is part of resources in the first BWP.
For example, as shown in fig. 24, the resource for transmitting SDT service is the resource a of the independent initial BWP (first BWP) within T1, the resource for receiving SSB is the resource B of the SSB within GAP1, and if there is an overlap between the resource a and the resource B in the time domain, the SDT service is transmitted in the overlapping time unit a, and the SSB is not transmitted, so as to improve the reliability of the SDT service.
As still another example, as shown in fig. 25, the resource for transmitting the SDT service is the resource A1 of the independent initial BWP (first BWP) within T2, the resource for receiving the update indication is the resource B1 of CORESET #0 within GAP2, and if there is overlap between the resource A1 and the resource B1 in the time domain, the SDT service is transmitted in the overlapping time unit B, and the update indication is not transmitted, so as to improve the reliability of the SDT service.
As yet another example, as shown in fig. 26, assume that the resource for transmitting SDT traffic is a resource A2 of an independent initial BWP (first BWP) within T5, the resource for receiving SSB is a resource B2 of SSB within GAP1, and the interval T1 between the resource A2 and the resource B2 in the time domain is smaller than the radio frequency tuning time T2. In T5, the terminal transmits SDT service on the independent initial BWP, and then, since T1 is smaller than the radio frequency tuning time T2, the terminal cannot receive the complete SSB even if it tunes to the B2 resource, affecting the reliability of the measurement by the terminal according to the SSB. The terminal continues to transmit the SDT service without switching to the resource where the SSB is located.
In some embodiments, to avoid or reduce collision of a third time-frequency resource with a fourth time-frequency resource, the third time-frequency resource and the fourth time-frequency resource may be configured to be spaced apart in the time domain by more than a threshold. Alternatively, the threshold may be a radio frequency tuning time. Illustratively, as shown in fig. 27, the time interval (T1) between the time domain resource GAP1 for receiving SSB and the time domain resource (T5) for transmitting SDT service is greater than the radio frequency tuning time T2. The time interval (T4) between the time domain resource GAP1 for receiving SSB and the time domain resource (T3) for transmitting SDT traffic is greater than the radio frequency tuning time T2.
It should be noted that some operations in the flow of the above-described method embodiments are optionally combined, and/or the order of some operations is optionally changed. The order of execution of the steps in each flow is merely exemplary, and is not limited to the order of execution of the steps, and other orders of execution may be used between the steps. And is not intended to suggest that the order of execution is the only order in which the operations may be performed. Those of ordinary skill in the art will recognize a variety of ways to reorder the operations described herein. In addition, it should be noted that details of processes involved in a certain embodiment herein apply to other embodiments as well in a similar manner, or that different embodiments may be used in combination.
Moreover, some steps in method embodiments may be equivalently replaced with other possible steps. Alternatively, some steps in method embodiments may be optional and may be deleted in some usage scenarios. Alternatively, other possible steps may be added to the method embodiments.
Moreover, the method embodiments described above may be implemented alone or in combination.
In some embodiments, the manner in which SSB measurements and/or update indications are received may be determined based on terminal capabilities.
Optionally, the terminal device sends the first indication information, and correspondingly, the network device receives the first indication information from the terminal device. The first indication information may be used to indicate capabilities of the terminal device. In this way, the network device can better configure appropriate resources or configuration for the terminal device according to the capability of the terminal device. For example, the first indication information may be used to indicate whether the terminal device supports that the resources corresponding to the first signal and/or the resources corresponding to coreset#0 are not included in the first BWP. For example, the first indication information is used to indicate that the terminal device does not expect the first signal to be included in the first BWP. For example, the first indication information is used to indicate that the terminal device desires to include the first signal in the BWP. For example, the first indication information is used to indicate that the terminal device needs (need) to include the first signal in the BWP.
Optionally, the network device may determine, according to the capability of the terminal device, a manner of configuring the first period of time in the first embodiment, instruct the terminal device to measure SSB in the corresponding resource and/or receive an update indication of the system information. In this way, the terminal device with a higher capability may perform SSB measurement and/or receive an update indication of system information on a frequency domain resource outside the first BWP. Alternatively, the network device may determine that, in the manner of the second embodiment, resources for receiving SSB (such as resources corresponding to NCD-SSB) and/or resources for receiving update indication are configured in the first BWP according to the capability of the terminal device. In this way, the terminal device may make SSB measurements and/or receive updated indications of system information within the first BWP. For example, the terminal device supports that the resources corresponding to the first signal and/or the resources corresponding to coreset#0 are not included in the first BWP, and the network device may instruct the terminal device to measure SSB and/or receive an update indication of the system information in the corresponding resources in a manner of configuring the first period of time. For example, the terminal device does not support the first BWP and does not include the resource corresponding to the first signal and/or the resource corresponding to coreset#0, and the network device may configure the resource for receiving SSB (such as the resource corresponding to NCD-SSB) and/or the resource for receiving the update indication in the first BWP.
In some embodiments, the manner in which the SSB measurements and/or the update indications are received is determined based on whether the network device is configured for the first period of time.
Optionally, if the network device configures the first period for the terminal device under the condition that the resources corresponding to the SSB and/or the resources corresponding to the coreset#0 are not included in the first BWP, the terminal device switches from the first BWP to other resources to perform SSB measurement and/or receive an update instruction of the system information according to the corresponding instruction information in the first period. Otherwise, if the network device does not configure the first period for the terminal device, the terminal device does not need to switch to other resources to perform SSB measurement and/or receive an update instruction of the system information. For example, the network device does not configure the terminal device with the first time period, the terminal device does not make SSB measurements at the first BWP and/or receives an update indication of the system information.
The combination scheme gives the network equipment greater flexibility in configuration, and the network equipment can select a proper mode according to actual conditions so that the terminal equipment measures the first signal (or the second signal) and/or receives the update indication of the system information.
