Abstract
Description
Processing method, communication device and storage medium Technical Field
[0001] The present application relates to the field of communication technology, and in particular to a processing method, communication equipment, and storage medium. Background Art
[0002] In existing protocols, the RACH (Random Access CHannel) process has a large delay during current cell switching. This is mainly manifested in the following: the RAR (Random Access Response) window starts at the first symbol of the earliest CORESET (CONntrol REsource SET). For cell switching scenarios based on L1 / L2 signaling, the RAR of the candidate cell is first transmitted to the current serving cell, and then sent from the current serving cell to the terminal device. There is a certain delay in the transmission of the RAR between the candidate cell and the current serving cell.
[0003] During the process of conceiving and implementing this application, the inventors discovered that the related technology has at least the following problems: if the terminal device directly monitors RAR in the RAR window defined by the current protocol, it may result in no RAR being monitored in the RAR window, or it may take a long time to monitor RAR.
[0004] And / or, based on the current protocol, when a timing advance command is applied upon receiving a random access response and a corresponding timer is started, when a cell handover is performed based on L1 / L2 signaling, the above solution may start the corresponding timer too early.

[0113] The purpose of this application, its features, and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings. The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and the accompanying text are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of this application to those skilled in the art by reference to specific embodiments.
[0114] Implementation Methods of the Application
[0115] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0116] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. Optionally, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined based on their explanation in the specific embodiment or further combined with the context of the specific embodiment.
[0117] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the recited features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.
[0118] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.
[0119] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.
[0120] It should be noted that in this article, step codes such as S10 and S20 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the order. When implementing the step, those skilled in the art may execute S20 first and then S10, etc., but these should all be within the scope of protection of this application.
[0121] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0122] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.
[0123] The communication equipment mentioned in this application can be a terminal device (such as a mobile terminal, specifically a mobile phone) or a network device (such as a base station). The specific reference needs to be clarified in the context.

It will be understood by those skilled in the art that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminals.
[0126] Please refer to Figure 1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.
[0127] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:
[0128] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and other components. Optionally, the RF unit 101 can also communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G or 6G, etc.
[0129] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.
[0130] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.
[0131] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.
[0132] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary.

[0391] Optionally, if the network device is configured to receive a random access response in the radio resource control signaling, when the cell is switched, the random access response transmitted by the physical random access channel (PRACH) in the candidate cell is first transmitted to the current serving cell, and then sent from the current serving cell to the terminal device. There is a certain delay in the transmission of the random access response (RAR) between the candidate cell and the current serving cell. If the random access response is directly monitored or received in the random access response window defined by the current protocol, it may result in the random access response not being monitored in the random access response window or the random access response monitoring or reception taking a long time.
[0392] In this embodiment, the network device sends radio resource control signaling and / or downlink control information, the terminal device receives the radio resource control signaling and / or downlink control information, and determines the starting point of the random access response window or the random access response monitoring starting point or the starting point of the response information medium access control control unit receiving window based on the radio resource control signaling and / or downlink control information to monitor or receive the random access response. This allows the terminal device to monitor or receive the random access response in a timely and / or accurate manner, reducing monitoring time.

The DCI is used to initiate a random access process in the candidate cell by PDCCH order. The network device determines a target RAR window parameter based on the delay between the candidate cell and the current serving cell, and indicates one of the configured N candidate RAR window parameters, i.e., the target RAR window parameter, through the value of the RAR window parameter field in the DCI, where N is an integer. The following options are available for providing these N candidate RAR window parameters:
[0400] Optionally, RRC adds a new RAR window parameter to configure N candidate RAR window parameters. The newly added parameter is a sequence or a list, and can configure N candidate RAR window parameters.
[0401] Optionally, the RRC adds N RAR window parameters to configure N candidate RAR window parameters, and each newly added parameter configures a candidate RAR window parameter.
[0402] Optionally, these N candidate RAR window parameters are default values, and the terminal device may obtain these N default values in advance.
[0403] Optionally, N or N pairs of candidate RAR window parameters are configured, each or each pair of candidate RAR window parameters corresponds to a candidate cell. For the random access process initiated by the PDCCH order in the candidate cell, the terminal device determines one or a pair of candidate RAR window parameters among the N or N pairs of candidate RAR window parameters according to the candidate cell identifier in the PDCCH order, that is, the target RAR window parameter, where N is an integer.
[0404] Optionally, for the method of providing the N or N pairs of candidate RAR window parameters, there are the following options:
[0405] Optionally, RRC adds a new RAR window parameter to configure N or N pairs of candidate RAR window parameters. The newly added parameter is a sequence or a list, and can configure N or N pairs of candidate RAR window parameters.
[0406] Optionally, the RRC adds N RAR window parameters to configure N or N pairs of candidate RAR window parameters, and each newly added parameter configures one or one pair of candidate RAR window parameters.
[0407] Optionally, these N or N pairs of candidate RAR window parameters are default values, and the terminal device may pre-acquire these N or N pairs of default values.
[0408] For example, the network device configures N pairs of candidate RAR window parameters, namely, time offset value and RAR window length. Each pair of candidate RAR window parameters corresponds to a candidate cell. The terminal device determines a pair of target RAR window parameters corresponding to the candidate cell according to the candidate cell identifier in the PDCCH order, and performs RAR monitoring or reception in the RAR window determined by the pair of target RAR window parameters.
[0409] Optionally, M candidate RAR window parameters are configured, and a RAR window parameter field is added to the downlink control information (e.g., DCI format 1_0), or reserved bits in the downlink control information (e.g., DCI format 1_0) are used as the RAR window parameter field. The DCI is used to initiate a random access process in the candidate cell by PDCCH order. The network device determines a target RAR window parameter based on the delay between the distributed unit (DU) to which the candidate cell belongs and the DU to which the current serving cell belongs. The value of the RAR window parameter field in the DCI indicates one of the configured M candidate RAR window parameters, namely, the target RAR window parameter, where M is an integer. The following options are available for providing these M candidate RAR window parameters:
[0410] Optionally, RRC adds a new RAR window parameter to configure M candidate RAR window parameters. The newly added parameter is a sequence or a list, and can configure M candidate RAR window parameters.
[0411] Optionally, the RRC adds M RAR window parameters to configure M candidate RAR window parameters, and each newly added parameter configures a candidate RAR window parameter.
[0412] Optionally, the M candidate RAR window parameters are default values, and the terminal device may obtain the M default values in advance.
[0413] Optionally, two candidate RAR window parameters are configured. Optionally, these two candidate RAR window parameters correspond to the candidate cell within the DU and the candidate cell between DUs, respectively. For example, if the PDCCH order initiates a random access process in the candidate cell, and the candidate cell and the current serving cell are in the same DU, that is, the candidate cell within the DU, then the candidate RAR window parameters corresponding to the candidate cell within the DU are used. For another example, if the PDCCH order initiates a random access process in the candidate cell, and the candidate cell and the current serving cell are not in the same DU, that is, the candidate cell between DUs, then the candidate RAR window parameters corresponding to the candidate cell between DUs are used. For the method of providing these two candidate RAR window parameters, there are the following optional solutions:
[0414] Optionally, RRC adds a new RAR window parameter to configure the two candidate RAR window parameters. The newly added parameter is a sequence or a list, and can configure the two candidate RAR window parameters.
[0415] Optionally, RRC adds two new RAR window parameters to configure the two candidate RAR window parameters, and each newly added parameter configures one candidate RAR window parameter.
[0416] Optionally, these two candidate RAR window parameters are default values, and the terminal device can obtain these two default values in advance.
[0417] There are two options for selecting the parameters of the RAR window:
[0418] Optionally, a RAR window parameter field is added to the downlink control information (e.g., DCI format 1_0), or the reserved bits in the downlink control information (e.g., DCI format 1_0) are used as the RAR window parameter field. The DCI is used to initiate a random access process in the candidate cell by PDCCH order. The network device determines a RAR window parameter based on whether the candidate cell belongs to a candidate cell within a DU or a candidate cell between DUs, and indicates one of the two pre-configured candidate RAR window parameters through the value of the RAR window parameter field in the DCI, namely, the target RAR window parameter.
[0419] Optionally, a candidate cell determination field within the DU is added to the downlink control information (for example: DCI format 1_0), or the reserved bits in the downlink control information (for example: DCI format 1_0) are used as the candidate cell determination field within the DU. The DCI is used to initiate a random access process in the candidate cell by PDCCH order. The network device determines the value of the candidate cell determination field within the DU based on whether the candidate cell is a candidate cell within the DU or a candidate cell between DUs. The terminal device selects one of the two pre-configured candidate RAR window parameters, i.e., the target RAR window parameter, based on the value of the candidate cell determination field within the DU in the DCI.
[0420] For example, the value of the candidate cell determination domain within a DU is 0, indicating that the candidate RAR window parameters corresponding to the candidate cells between DUs are used, i.e., the target RAR window parameters, and / or the value of the candidate cell determination domain within a DU is 1, indicating that the candidate RAR window parameters corresponding to the candidate cells within the DU are used, i.e., the target RAR window parameters.
[0421] For another example, the value of the candidate cell determination domain within the DU is 1, indicating that the candidate RAR window parameters corresponding to the candidate cells between the DUs are used, that is, the target RAR window parameters, and / or the value of the candidate cell determination domain within the DU is 0, indicating that the candidate RAR window parameters corresponding to the candidate cells within the DU are used, that is, the target RAR window parameters.
[0422] Optionally, using the default method, the terminal device selects one of the two pre-configured candidate RAR window parameters according to whether the candidate cell is a candidate cell within the DU or a candidate cell between DUs, namely, the target RAR window parameter. For example, if the candidate cell is a candidate cell within the DU, the candidate RAR window parameter corresponding to the candidate cell within the DU is used, namely, the target RAR window parameter. If the candidate cell is a candidate cell between DUs, the candidate RAR window parameter corresponding to the candidate cell between DUs is used, namely, the target RAR window parameter.
[0423] In the technical solution of this embodiment, the network device sends first information, and the terminal device determines a first starting point based on the first information. Optionally, the first starting point includes at least one of a starting point of a random access response window, a random access response monitoring starting point, and a starting point of a response information medium access control control unit receiving window. The terminal device monitors or receives the random access response or the response information medium access control control unit based on the first starting point, thereby enabling the terminal device to monitor or receive the random access response in a timely and / or accurate manner, thereby reducing monitoring time.

There is a certain delay in the transmission of the random access response (RAR) between the candidate cell and the current serving cell. If the random access response is directly monitored or received in the random access response window defined by the current protocol, it may result in the random access response not being monitored in the random access response window or the random access response monitoring or reception taking a long time.
