Detailed Description

The wireless communication system of the embodiment of the invention comprises a terminal and network equipment. The terminal may also be referred to as a terminal Device or a User Equipment (UE), and the terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal is not limited in the embodiment of the present invention. The network device may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), and the Base Station may be referred to as a node B, an enodeb, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, and is not limited to a specific terminology as long as the same technical effect is achieved.

Optionally, the random access procedure in the embodiment of the present invention may be selected as a 2-step random access procedure (2-step RACH procedure), and further may be selected as a 2-step random access procedure in a connected state. As shown in fig. 1, the corresponding 2-step random access procedure may include the following steps:

step 11: a network device such as the gNB configures configuration information for the 2-step RACH for the UE. For example, the configuration information includes: and sending resource information corresponding to the random access request (MsgA) and the random access response (MsgB).

Step 12: the UE triggers a 2-step RACH procedure, sending MsgA to the gNB, such as over a PUSCH (Physical Uplink Shared Channel), which includes a UE identity (UE ID). Meanwhile, the UE may also send PRACH (Physical Random Access Channel) information to the gNB.

Step 13: after sending MsgA, the UE listens for MsgB reception for a certain period of time (e.g., within a RAR (Random Access Response) reception time window). While during the listening to MsgB, i.e., before the triggered 2-step RACH procedure is finished, the UE may receive a Bandwidth Part (BWP) change command (e.g., C-RNTI PDCCH indicates the target BWP identity for the change).

In addition, if the UE fails to receive MsgB, msgA may be resent.

For a connected UE, in case of triggering 2-step RACH due to "uplink data arrival and uplink out-of-sync", after the gNB successfully receives MsgA, the gNB will send MsgB. For the MsgB transmission, the gNB may schedule transmission of a Downlink PDSCH (Physical Downlink Shared Channel) through a Physical Downlink Control Channel (PDCCH) (Cell Radio Network Temporary Identity ), where the PDSCH may include a MAC CE (media access Control Element) for Absolute uplink Timing of the UE (i.e., an Absolute Timing Advance Command MAC CE) for uplink synchronization of the UE.

Optionally, for the 2-step random access process, the random access request may also be denoted as Msg1, and the corresponding random access response is denoted as Msg2, which is not limited in this embodiment.

Optionally, the UE may be configured with a plurality of different frequency ranges in 1 cell. The UE can only have 1 BWP active at the same time. A network device such as the gNB may transform the UE-activated BWP by carrying the transformed target BWP identification through C-RNTI PDCCH.

Referring to fig. 2, fig. 2 is a flowchart of a method for transforming operating frequency points according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 201: in listening for a random access response of an initiated random access procedure, a BWP change command is received.

Alternatively, the random access procedure in this embodiment may be a 2-step random access procedure (2-step RACH procedure) in a connected state, that is, a 2-step RACH procedure triggered by a terminal in a connected state. The BWP transform command is sent, for example, through C-RNTI PDCCH carrying the transformed target BWP id to transform the terminal-activated BWP.

For example, a connected UE initiates a 2-step RACH procedure due to uplink failure and uplink data arrival, and sends MsgA, where the MsgA includes an identity C-RNTI of the UE. Thereafter, the UE listens to the MsgB for reception and, in the course of listening to the MsgB, receives the BWP transform command.

Step 202: performing a BWP transformation, or ignoring the BWP transformation command.

Wherein ignoring the BWP transform command in this step 202 may be understood as discarding the BWP transform.

In the method for transforming the working frequency points in the embodiment of the invention, when the terminal receives the BWP transformation command in the process of monitoring the random access response of the initiated random access process (such as a 2-step random access process), the BWP transformation can be executed or the BWP transformation command is ignored, so that the terminal behavior is defined, and the random access initiation times are reduced under the condition of avoiding the random access failure as much as possible.

Optionally, before performing the BWP transform in step 202, the method may further include:

determining whether to perform BWP transform according to whether the BWP transform command includes scheduling information of a PDSCH.

As an optional implementation manner, if the BWP conversion command includes scheduling information of the PDSCH, determining to perform BWP conversion; and if the BWP conversion command does not include the scheduling information of the PDSCH, determining not to perform BWP conversion.

Optionally, the performing BWP transformation in step 202 may further include the following cases:

case 1: and if the received BWP conversion command comprises scheduling information of a PDSCH, executing the BWP conversion.

In this case 1, if a random access response is received on the PDSCH, the terminal may determine that the initiated random access procedure is successfully completed. And if no random access response is received on the PDSCH, the terminal may stop the initiated random access procedure.

Case 2: and if the received BWP conversion command does not comprise the scheduling information of the PDSCH, executing the BWP conversion.

In this case 2, the terminal may stop the initiated random access procedure after performing the BWP transform.

Alternatively, for the above cases 1 and 2, after stopping the initiated random access procedure, the terminal may reinitiate the random access procedure. If, during the process of re-initiating the random access procedure, an absolute uplink timing MAC CE is received outside the receiving time window of the random access response (e.g., msgB) and (e.g., the absolute uplink timing MAC CE is received before the MsgB receiving timer (e.g., msgB-ResponseWindow) is started, or the absolute uplink timing MAC CE is received before the MsgA is sent), the terminal may discard the absolute uplink timing MAC CE or not apply the uplink timing value indicated in the absolute uplink timing MAC CE.

Optionally, the reinitiating the random access procedure may include: if the target BWP indicated by the received BWP conversion command configures the random access resource, re-initiating the random access process on the target BWP; or, if the target BWP indicated by the received BWP conversion command does not configure the random access resource, re-initiating the random access procedure on the first BWP, where the first BWP is a preset BWP configured with the random access resource, for example, the preset BWP is an initial BWP agreed by the protocol.

Optionally, the type of the initiated random access procedure is the same as the type of the re-initiated random access procedure. For example, if the type of the random access procedure stopped by the UE is 2-step RACH, the type of the random access procedure initiated again is also 2-step RACH.

In one embodiment, for a connected 2-step RACH procedure, after the UE sends MsgA, in the process of receiving MsgB, if a BWP change command is received (e.g., via C-RNTI PDCCH):

1) If the BWP switch command includes scheduling information for the downlink PDSCH, the UE selects to perform BWP switching. Further, if the PDSCH scheduled by the C-RNTI PDCCH of the UE contains Msg2 information of the UE, the UE may determine that the 2-step RACH procedure is successfully completed; and if the PDSCH scheduled by the C-RNTI PDCCH of the UE does not contain the Msg2 information of the UE, the UE can stop the 2-step RACH process and reinitiate the 2-step RACH process at the target BWP.

2) If the BWP transform command does not include scheduling information for the downlink PDSCH, the UE selects to perform BWP transform. Further, after selecting to perform BWP transition, the UE may stop the 2-step RACH procedure and re-initiate the 2-step RACH procedure at the target BWP.

In this embodiment of the present invention, after performing BWP conversion in step 202, the terminal behavior may further include any one of the following:

(1) The initiated random access procedure is stopped.

Further, the stopping of the initiated random access procedure in (1) may include:

stopping the initiated random access process if the received BWP conversion command comprises scheduling information of a PDSCH and no random access response is received on the PDSCH;

or, if the received BWP change command does not include the scheduling information of the PDSCH, stopping the initiated random access procedure.

Further, the terminal may re-initiate the random access procedure after stopping the initiated random access procedure. If the absolute uplink timing MAC CE is received outside the receiving time window of the random access response (e.g., msgB) during the process of re-initiating the random access procedure (e.g., the absolute uplink timing MAC CE is received before the MsgB receiving timer (e.g., msgB-ResponseWindow) is started, or the absolute uplink timing MAC CE is received before the MsgA is sent), the terminal may discard the absolute uplink timing MAC CE, or not apply the uplink timing value indicated in the absolute uplink timing MAC CE.

(2) If the received BWP change command includes scheduling information of the PDSCH and a random access response (e.g., including an absolute uplink timing MAC CE) is received on the PDSCH, it is determined that the initiated random access procedure is successfully completed.

(3) If the received BWP change command includes scheduling information of the PDSCH and a random access response (e.g., including an absolute uplink timing MAC CE) is received on the PDSCH, discarding the random access response (e.g., discarding the received absolute uplink timing MAC CE or not applying the uplink timing value indicated in the absolute uplink timing MAC CE).

In another embodiment, for the connected 2-step RACH procedure, after the UE sends MsgA, in the process of receiving MsgB, if the BWP change command is received, the UE behavior includes any one of the following:

executing BWP transformation and abandoning the BWP transformation.

Further, after performing BWP transformation, the UE behavior may include any of:

1) The UE stops the 2-step RACH procedure in progress.

2) If the BWP change command does not include scheduling information of the downlink PDSCH (e.g., the BWP change command includes an Uplink grant for PUSCH transmission), the UE stops the 2-step RACH procedure in progress.

3) If the BWP change command includes scheduling information of a downlink PDSCH, the UE receives MsgB on the PDSCH. Thereafter, the UE behavior includes any one of:

if the MsgB content corresponding to the UE is received on the PDSCH (e.g., the MsgB contains an absolute uplink timing MAC CE), the UE determines that the 2-step random access procedure is successfully completed.

If the MsgB content corresponding to the UE is received on the PDSCH (e.g., the MsgB contains an absolute uplink timing MAC CE), the UE discards the MsgB content (e.g., the UE discards the received absolute uplink timing MAC CE, or does not apply the uplink timing value indicated in the absolute uplink timing MAC CE).

Iii if the MsgB content corresponding to the UE is not received on the PDSCH (e.g., the MsgB does not contain the absolute uplink timing MAC CE), the UE stops the 2-step RACH procedure in progress.

Further, according to the above-mentioned determination condition, if the UE stops the 2-step RACH procedure in progress (e.g., stops the MsgB reception timer (e.g., msgB-ResponseWindow)), the UE re-initiates the random access procedure.

Further, if the absolute uplink timing MAC CE is received outside the receiving time window of the MsgB during the "UE re-initiates the random access procedure" (e.g., the UE re-initiates the random access procedure, the absolute uplink timing MAC CE is received before the MsgB receiving timer (e.g., msgB-ResponseWindow) starts), or the UE re-initiates the random access procedure, the absolute uplink timing MAC CE is received before the MsgA is sent, the UE discards the received absolute uplink timing MAC CE, or does not apply the uplink timing value indicated in the absolute uplink timing MAC CE.

Further, if the UE re-initiates the random access procedure, the type of the re-initiated random access procedure is the same as the type of the random access procedure that was stopped last time. For example, if the type of the random access procedure stopped by the UE is 2-step RACH, the type of the random access procedure restarted is also 2-step RACH.

Further, if the UE re-initiates the random access procedure and the target BWP indicated by the BWP transformation command does not configure the random access resource, the UE transforms the activated BWP to the protocol-agreed BWP with the random access resource (e.g., initial BWP).

Thus, by the method in this embodiment, when the UE initiates a 2-step RACH procedure and receives a BWP change command, BWP change is performed through a predefined behavior, and whether to initiate a new random access procedure is determined through the predefined behavior, so as to reduce the number of times of random access initiation while avoiding random access failure as much as possible.

Referring to fig. 3, fig. 3 is a flowchart of a method for transforming working frequency points according to an embodiment of the present invention, where the method is applied to a network device, and as shown in fig. 3, the method includes the following steps:

step 301: a random access request of a terminal is received.

Alternatively, the random access procedure in this embodiment may be a 2-step random access procedure (2-step RACH procedure) in a connected state, that is, a 2-step RACH procedure triggered by a terminal in a connected state. The random access request for the terminal may be denoted as Msg1 or MsgA under a 2-step RACH procedure.

Step 302: in the case of transmitting the random access response, the BWP conversion command is not transmitted.

Optionally, the random access response sent by the network device may be Msg2 or MsgB in a 2-step RACH procedure.

In one embodiment, for a connected 2-step RACH procedure, after the UE sends MsgA, the network device such as gNB disables the sending of a BWP transform command while sending MsgB.

In another embodiment, the UE initiates a 2-step RACH procedure and sends the MsgA. For example, a connected UE initiates a 2-step RACH procedure due to uplink failure and uplink data arrival, and sends MsgA, where the MsgA includes an identity C-RNTI of the UE. The UE listens for the reception of MsgB. The gNB does not send a BWP transform command to the UE during the process of the UE listening to the MsgB. For example, C-RNTI PDCCH does not contain a BWP transform command after the gNB receives the UE's MsgA, before and while it sends the MsgB down.

In this way, by not transmitting the BWP change command in the case of transmitting the random access response, the terminal can be prevented from changing BWP during the random access procedure, thereby reducing the number of random access failures.

Optionally, after step 301, the method may further include:

if the BWP conversion command is sent and the BWP conversion command comprises scheduling information of a PDSCH, the network equipment sends a random access response on the PDSCH so that the terminal successfully receives the random access response and the successful completion of the random access process is ensured.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a terminal according to an embodiment of the present invention, and as shown in fig. 4, the terminal 40 includes:

a first receiving module 41, configured to receive a BWP conversion command in a process of monitoring a random access response of an initiated random access process;

a processing module 42 for performing a BWP transformation or ignoring the BWP transformation command.

Optionally, the terminal 40 further includes:

a determining module for determining whether to perform BWP transform according to whether the BWP transform command includes scheduling information of a PDSCH.

Optionally, after performing the BWP transform, the processing module 42 is further configured to:

stopping the initiated random access procedure;

or, when the BWP change command includes scheduling information of a PDSCH and a random access response is received on the PDSCH, determining that the initiated random access procedure is successfully completed;

or, when the BWP change command includes scheduling information of the PDSCH and a random access response is received on the PDSCH, discarding the random access response.

Optionally, the processing module 42 is further configured to:

stopping the initiated random access procedure when the BWP transform command includes scheduling information of a PDSCH and no random access response is received on the PDSCH;

or, when the BWP change command does not include scheduling information of the PDSCH, stopping the initiated random access procedure.

Optionally, the processing module 42 is further configured to: re-initiating the random access procedure after stopping the initiated random access procedure.

Optionally, if the absolute uplink timing MAC CE is received outside the receiving time window of the random access response in the process of re-initiating the random access procedure, the processing module 42 is further configured to:

and discarding the absolute uplink timing MAC CE, or not applying the uplink timing value indicated in the absolute uplink timing MAC CE.

Optionally, the processing module 42 is further configured to:

re-initiating a random access procedure on the target BWP when the target BWP indicated by the BWP transformation command is configured with random access resources;

or, when the target BWP indicated by the BWP change command is not configured with the random access resource, re-initiating the random access procedure on the first BWP, where the first BWP is a preset BWP configured with the random access resource.

Optionally, the type of the initiated random access procedure is the same as the type of the re-initiated random access procedure.

Optionally, the initiated random access process is a connected 2-step random access process.

The image frames processed by the graphic processor 6041 may be stored in the memory 609 (or other storage medium) or transmitted via the radio frequency unit 601 or the network module 602. The microphone 6042 can receive sounds and can process such sounds into audio data.

Specifically, the light sensor includes an ambient light sensor that can adjust the brightness of the display panel 6061 according to the brightness of ambient light, and a proximity sensor that can turn off the display panel 6061 and/or the backlight when the terminal 600 is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), detect the magnitude and direction of gravity when stationary, and can be used to identify the terminal posture (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration identification related functions (such as pedometer, tapping), and the like; the sensors 605 may also include a fingerprint sensor, a pressure sensor, an iris sensor, a molecular sensor, a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, etc., which are not further described herein.

Touch panel 6071, also referred to as a touch screen, may collect touch operations by a user on or near it (e.g., operations by a user on or near touch panel 6071 using a finger, stylus, or any suitable object or accessory). The touch panel 6071 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 610, receives a command from the processor 610, and executes the command. In addition, the touch panel 6071 can be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave.

Although in fig. 6, the touch panel 6071 and the display panel 6061 are two independent components to realize the input and output functions of the terminal, in some embodiments, the touch panel 6071 and the display panel 6061 may be integrated to realize the input and output functions of the terminal, and this is not limited here.
