Description

[Technical Field]

[0001] (Cross-Reference to Related Application) The present disclosure claims priority to Chinese Patent Application No. CN202210591041.7 filed on May 27, 2022, entitled "Signal Transmission Method and Apparatus, Signal Reception Method and Apparatus", the entire disclosure of which is incorporated herein by reference.

[0002] Embodiments of the present disclosure relate to the field of communications, and in particular, to a signal transmission method and apparatus, a signal reception method and apparatus, a storage medium, and an electronic device. [Background Art]

[0003] The large-scale commercialization of the 5th Generation Mobile Communication System (5G) and New Radio (NR) is accelerating the transformation of the economy and society towards digitalization, networking, and intelligence, driving the network into a new era where everything is interconnected. The rapidly emerging application demands in areas such as smart cities, intelligent transportation, and intelligent industrial production are driving the development of differentiated network equipment capabilities, diversified network functions, and intelligent network management and control, further accelerating the arrival of the 6th Generation Mobile Communication System (6G), which intelligently interconnects everything. In typical 6G application scenarios such as smart cities, intelligent transportation, and smart homes, the presence of a large number of highly differentiated smart automation devices is creating increasingly stringent communication demands for extremely low latency, extremely high reliability, extremely large bandwidth, and massive access. Intelligent automation applications also demand high precision and high resolution in sensing capabilities. On the one hand, the rapid increase in the number of wireless communication and sensing devices is exacerbating the conflict between the limitless increase in service demand and limited wireless resources and computing power. On the other hand, realizing the 6G vision requires closed-loop information stream processing that is distributed hierarchically through the acquisition of environmental sensing information, information exchange and sharing, intelligent information processing, and control information (including control information for communication networks and control commands for application execution devices).

[0004] In related technologies, in the fifth-generation mobile communication system New Radio, during the random access process, the terminal selects only one random access channel (Physical Random Access Channel, abbreviated as PRACH) resource corresponding to one beam direction and transmits a random access signal (preamble) to initiate the random access process. Thus, if the performance of the UE is limited, the PRACH resources are limited, or if there are too many UEs selecting the same beam direction, the preamble sequences for the same beam direction will collide, further preventing the UE from accessing the system properly or increasing the access delay for the UE. Therefore, this random access method cannot meet the communication demands for new applications that will constantly emerge in the post-5G / 6G era, such as extremely low latency, extremely high reliability, extremely large bandwidth, and high volume of access.

[0005] As can be seen from this, in related technologies, the terminal can select only a random access channel resource corresponding to one beam direction to transmit random access signals. Thus, the performance of the UE is limited, the UE may not be able to access the system properly, or the access delay of the UE may increase, making it impossible to meet the communication demands in terms of very low latency, very high reliability, very large bandwidth, and large volume of access. Currently, no effective solution has been proposed to the above problems that exist in related technologies. [Overview of the Initiative] [Problems that the invention aims to solve]

[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0015] Furthermore, terms such as "first," "second," etc., in the specification, claims, and drawings of this disclosure are not used to describe a specific order or sequence, but rather to distinguish similar subjects.

[0016] Embodiments of the methods according to the embodiments of this disclosure can be implemented in a mobile terminal, a computer terminal, or a similar computing device. Taking implementation in a mobile terminal as an example, Figure 1 is a hardware block diagram of a mobile terminal for a signal transmission method according to an embodiment of this disclosure. As shown in Figure 1, the mobile terminal may include one or more (only one is shown in Figure 1) processors 102 (the processors 102 include, but are not limited to, processing units such as a microprocessor MCU or a programmable logic device FPGA) and memory 104 for storing data, and the mobile terminal may further include transmission equipment 106 and input / output equipment 108 for communication functions. As will be understood by those skilled in the art, the configuration shown in Figure 1 is merely schematic and does not limit the configuration of the mobile terminal. For example, the mobile terminal may further include more or fewer components than those shown in Figure 1, or have a different arrangement than that shown in Figure 1.

Memory 104 may include high-speed random-access memory and may further include non-volatile memory such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, memory 104 may further include memory installed remotely from the processor 102, and these remote memories may be connected to a mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0018] The transmission device 106 transmits and receives data via one network. Specific examples of the network may include a wireless network provided by a communication carrier of a mobile terminal. In one example, the transmission device 106 includes a network adapter (abbreviated as NIC, Network Interface Controller) that is connected to another network device via a base station and is capable of communicating with the Internet. In one example, the transmission device 106 may be a Radio Frequency (abbreviated as RF) module that communicates with the Internet via a wireless method.

[0019] In this embodiment, a signal transmission method is provided. Figure 2 is a flowchart of a signal transmission method according to an embodiment of the present disclosure. As shown in Figure 2, the flow includes the following steps S202 and S204.

[0020] In step S202, a plurality of target beams are determined. In step S204, a random access signal is transmitted to a first node based on resources respectively corresponding to the plurality of target beams.

[0021] The execution subject of the above steps may be a device with signal transceiving capability, for example, a terminal device, a processor or a processing module in a terminal device, or may be another processing device or processing unit with similar processing capability. The first node may be a base station, or a specific module in a base station, or another network node capable of communicating with a base station. The random access signal may be referred to as Message 1, that is, Msg1.

[0022] In the following, a description is given by taking that a terminal device (i.e., UE) performs the above operations as an example (this is only an exemplary description, and other devices or modules may perform the above operations in actual operation). First, related technologies according to embodiments of the present disclosure are described.

[0023] In an embodiment of the present disclosure, a beam may be represented by a determined resource set, and the resource set may include at least one of transmit-side precoding, receive-side precoding, transmit-side antenna port configuration, a transmit-side antenna weight vector, a transmit-side antenna weight matrix, receive-side antenna port configuration, a receive-side antenna weight vector, a receive-side antenna weight matrix, determined time domain resources and / or frequency domain resources and / or code sub-resources. Accordingly, a beam index may be replaced with a resource index. A beam may be a transmission (transmission / reception) scheme, and the transmission scheme may include spatial division multiplexing, frequency domain and / or time domain diversity, etc.

[0024] In a preferred embodiment, a beam includes at least one of a transmit beam, a receive beam, precoding, a precoding matrix, a precoding matrix index, a pair of a receive beam and a transmit beam, and a pair of a transmit beam and a receive beam.

[0025] In a preferred embodiment, when the transmission scheme of a second channel / signal / resource references or uses the transmit beam used by a first channel / signal / resource, it can be said that the second channel and the first channel use the same transmit beam, and the transmit beam of the first channel / signal / resource is represented by the determined resource set.

[0026] In a preferred embodiment, when the reception scheme of a second channel / signal / resource references or uses the receive beam used by a first channel / signal / resource, it can be said that the second channel and the first channel use the same receive beam, and the receive beam of the first channel / signal / resource is represented by the determined resource set.

[0027] In a preferred embodiment, one target beam corresponds to one beam direction, and a plurality of target beams may correspond to the same beam direction or different beam directions.

[0028] In the above embodiment, multiple target beams can be determined, and a random access signal can be transmitted to the first node based on the resources corresponding to each of the multiple target beams. In this way, it is possible to transmit a random access signal to the first node using resources that can transmit random access signals corresponding to each of the multiple target beams. This avoids a situation where, if a failure occurs when only a resource corresponding to a single beam is used, it becomes impossible to transmit a random access signal to the first node. This solves the technical problem in related technologies where random access signals can only be transmitted by resources corresponding to a single beam in the random access process, and achieves the technical effect of being able to transmit random access signals using resources corresponding to each of the multiple beams, thereby meeting communication demands such as extremely low latency, extremely high reliability, ultra-wide bandwidth, and high volume of access.

[0029] In an exemplary embodiment, the step of determining a plurality of target beams includes at least one of the following: detecting a downlink channel and selecting a plurality of target beams based on the detection result; measuring a downlink signal and selecting a plurality of target beams based on the measurement result; selecting a plurality of target beams from stored beams; acquiring a plurality of target beams from a plurality of beams set by the first node; and selecting a target resource group from a plurality of set resource groups and selecting a plurality of target beams from a plurality of beams corresponding to the target resource group. In this embodiment, the target resource group may include PRACH time-frequency resources and / or preamble resources on PRACH, and when selecting a plurality of target beams from a plurality of beams corresponding to the target resource group, there may be a larger number of beams corresponding to the target resource group, and a plurality of target beams may be selected from among them, and the beams corresponding to the target resource group may be pre-set, and when determining a plurality of target beams, detection or measurement may be performed on the downlink channel, and a target beam corresponding to one or more downlink beams may be selected based on the detection or measurement result, for example, Based on this, if four downlink beams are selected, the UE can select two uplink beams corresponding to the downlink beams as target beams from the four downlink beams, based on the correspondence between the uplink beams and the downlink beams (the correspondence may be predefined, notified by signaling, or determined by negotiation between the UE and the base station). Furthermore, if the target beams are determined in a manner in which multiple target beams are obtained from multiple beams set by the first node, the first node may pre-set more beams, and then the UE may select multiple target beams from these more beams.

[0030] In an exemplary embodiment, the step of transmitting a random access signal to a first node based on resources corresponding to each of the multiple target beams includes the steps of: determining the transmission power for transmitting the random access signal on the target beams; determining a first beam from the multiple target beams based on the transmission power, wherein the number of first beams is one or more and is less than or equal to the number of target beams; and transmitting the random access signal on the resources corresponding to the first beam. In this embodiment, it is necessary to determine the first beam based on the transmission power, and the first beam may be one or more beams selected from the target beams according to a specific selection method (e.g., a pre-set priority for the beams, a frequency of beam use, etc.), or of course, one or more beams randomly selected from the target beams, and the number of first beams may also be adjusted based on actual circumstances. The above selection method for the first beam is merely exemplary, and the first beam is not limited to the above selection method.

[0031] In one exemplary embodiment, the step of determining a first beam from a plurality of target beams based on the transmit power includes determining a corresponding target beam whose transmit power is less than or equal to a first threshold as the first beam. In this embodiment, the first threshold may be a preset value, the maximum transmit power supported by the first node or the maximum transmit power set for the first node, all corresponding target beams whose transmit power is less than or equal to the first threshold may be determined as the first beam, or a portion of target beams whose transmit power is less than or equal to the first threshold may be determined as the first beam, and the setting of the first threshold can be flexibly adjusted according to the actual application situation.

[0032] In one exemplary embodiment, the method further includes the steps of: transmitting a random access signal to a first node based on resources corresponding to each of the multiple target beams; obtaining a first response message transmitted by the first node; and transmitting an uplink message to the first node based on uplink channel resources set by uplink channel setting information in the first response message, wherein the uplink message includes at least one of first indication information indicating whether or not to use a first active beam, and identification information of a second node transmitting the uplink message, the first active beam being a target beam for the random access signal corresponding to the first response message, and the beam corresponding to the first response message being a second active beam. In this embodiment, the first response message (or second message, i.e., Msg2) is sent back by the first node based on the reception of a random access signal transmitted by the second node, that is, the first response message is a response message to the random access signal, and there is a correspondence between the first active beam and the second active beam, for example, one first active beam can correspond to one second active beam, and the uplink message is also called the third message, i.e., Msg3.

[0033] In one exemplary embodiment, after the step of sending an uplink message to the first node, the method further includes the steps of: if the first node determines, based on first indication information in the received uplink message, that the second node will no longer use the first active beam, then terminating the transmission of a second response message, which is a response message to the uplink message, to the second node on the resource corresponding to the second active beam; and if the first node determines, based on first indication information in the received uplink message, that the second node will use the first active beam, then transmitting a second response message to the second node on the resource corresponding to the second active beam. In this embodiment, if the first node determines that the received uplink message does not contain first indication information, the first node transmits a second response message to the second node on the resource corresponding to the second active beam.

[0034] In one exemplary embodiment, after the step of sending an uplink message to the first node, the method further includes the steps of the first node receiving the uplink message, and if the first indication information contained in at least one of the uplink messages received by the first node within one time window indicates that the first active beam will no longer be used, the first node selects at least one first active beam from the first active beams that will no longer be used as indicated by the second node, and continues to send a second response message, which is a response message to the uplink message, to the second node on the resource corresponding to the second active beam corresponding to the selected at least one first active beam.In this embodiment, in the random access process, uplink messages are scheduled by the information packet of the first response message. However, the information packet of the first response message contains only the index information of the random access signal. At the same time, since the random access signal is common to terminals using the same beam, it cannot be guaranteed that only one terminal will use one beam to transmit an uplink message. In other words, there may be cases where multiple terminals use the same beam to transmit uplink messages. Because uplink messages may collide when multiple terminals use the same beam, the base station modifies the terminal's decision to avoid the base station failing to detect the uplink message for that beam, or conversely, detecting the uplink message for a beam abandoned by a terminal, and to guarantee a random access flow. To avoid the base station failing to detect uplink messages for a beam, and conversely detecting uplink messages for a beam abandoned by a terminal, and to ensure random access flow, the base station can modify the terminal's decision, that is, to complete the random access flow by selecting at least one first active beam from the first active beams that are still being used as indicated by the second node, and to avoid the base station failing to detect uplink messages for a beam that is still being used as indicated by the second node, and to ensure random access flow, the base station can modify the terminal's decision, that is, to complete the random access flow by selecting at least one first active beam from the first active beams that are still being used as indicated by the second node.

[0035] In one exemplary embodiment, after the step of sending an uplink message to the first node, the method verifies that if no target downlink channel is received on the resource corresponding to the second effective beam corresponding to the indicated unused first effective beam, the use of the first effective beam is abandoned; and if a target downlink channel is received on the resource corresponding to the second effective beam corresponding to the indicated unused first effective beam, and the control information in the target downlink channel includes confirmation that the first effective beam is not being used, the method verifies that the target downlink channel is not being detected on the resource corresponding to the second effective beam corresponding to the first effective beam; and the indicated unused first The method further includes at least one of the following steps: a target downlink channel transmitted by the first node is received on a resource corresponding to a second effective beam corresponding to an effective beam, and the control information in the target downlink channel includes information that the first effective beam is being used, and the method continues to detect the second response message based on scheduling information for the second response message in the target downlink channel; and a target downlink channel transmitted by the first node is received on a resource corresponding to a second effective beam corresponding to an indicated unused first effective beam, and the control information in the target downlink channel includes scheduling information for the second response message in an active state, and the method continues to detect the second response message based on scheduling information for the second response message in an active state.In this embodiment, if the terminal indicates that the target downlink channel transmitted from the base station is not received on the resource corresponding to the second effective beam corresponding to the unused first effective beam, the terminal will abandon the use of the first effective beam based on that situation. If the terminal indicates that the target downlink channel transmitted from the base station is received on the resource corresponding to the second effective beam corresponding to the indicated unused first effective beam, and the control information in the target downlink channel includes confirmation information that the first effective beam is not used, the terminal will confirm that it will not continue to detect the target downlink channel on the resource corresponding to the second effective beam corresponding to the first effective beam based on that situation. If a target downlink channel transmitted from the base station is received on the resource corresponding to the beam, and the control information in the target downlink channel includes information that the first effective beam is to be used, the terminal continues to detect the second response message based on the scheduling information of the second response message in the target downlink channel, based on the situation. If a target downlink channel transmitted from the base station is received on the resource corresponding to the second effective beam corresponding to the indicated unused first effective beam, and the control information in the target downlink channel includes scheduling information for a second response message that is in an effective state, the terminal continues to detect the second response message based on the scheduling information, based on the situation.

[0036] In one exemplary embodiment, the step of sending an uplink message to the first node based on the uplink channel resource configured by the uplink channel configuration information in the first response message includes the steps of selecting one or more first response messages from the acquired first response messages, and sending the uplink message to the first node using the uplink channel resource configured by the uplink channel configuration information in the selected first response messages. In this embodiment, the information packets of the first response message are not necessarily contained in a single first response message, but may be distributed across multiple first response messages. Therefore, an uplink message may be sent to the base station by selecting an uplink channel resource configured by the uplink channel configuration information of one or more first response messages from the acquired first response messages. If an uplink message is optionally sent, it may be implemented as follows: A predetermined number of first beams are selected from the beams that received the random access signal, and the uplink message is sent to the first node using the resources corresponding to the first beams. That is, the UE may selectively send Msg3 (i.e., uplink messages) corresponding to some of the beams.

[0037] In an exemplary embodiment, the step of transmitting an uplink message to the first node includes the step of determining the uplink message that does not need to be transmitted on the resource corresponding to the first active beam if at least one of the following rules is met: the uplink message is transmitted on the resource corresponding to the first active beam in which the transmission power of the uplink message exceeds a second threshold; the configured resource size of the uplink message does not meet a first demand; the channel quality performance of the received first response message does not meet a second demand; and other uplink messages other than the uplink message that does not need to be transmitted are transmitted to the first node. In this embodiment, the second threshold may be a preset value, or it may be set as the maximum transmit power supported by the first node or the maximum transmit power set for the first node. When transmitting an uplink message on the resource corresponding to the first active beam in which the transmit power of the uplink message exceeds the second threshold, it is possible to determine which uplink message does not need to be transmitted on the resource corresponding to the first active beam. The first demand may be bandwidth, data access volume, etc., and the second demand may be delay, reliability, efficiency, etc. The examples of the second threshold, first demand, and second demand described above are merely illustrative, and the second threshold, first demand, and second demand are not limited to these examples.

[0038] In one exemplary embodiment, after the step of sending an uplink message to the first node, the method further includes the step of receiving a target downlink channel transmitted from the first node and determining whether to continue using the first active beam based on the target downlink channel, wherein if the target downlink channel indicates that it should not continue using the first active beam, the method does not continue to detect a second response message which is a response message to the uplink message, and if the target downlink channel indicates that it should continue using the first active beam, the method continues to detect a second response message. In this embodiment, rather than the target downlink channel directly instructing the second node not to continue using the first active beam, the method determines that the resource allocation information in the second response message is in an active state by obtaining indication information contained in the resource allocation information of the second response message, thereby instructing the second node to decode the control information contained in the target downlink channel, and determining that the resource allocation information of the second response message is in an active state, and the first node determines that it should continue using the first active beam.

[0039] In one exemplary embodiment, the step of obtaining a first response message returned by the first node based on the received random access signal includes the steps of: detecting a target downlink channel transmitted by the first node within a target time window after the random access signal has been transmitted, wherein the target control information of the target downlink channel includes scheduling information for the first response message; and detecting and receiving the first response message based on the scheduling information for the first response message, the method further includes the step of terminating the detection of the target downlink channel within the target time window after the step of obtaining a first response message returned by the first node based on the received random access signal. In this embodiment, since the information packet of the first response message may be carried on multiple first response messages within a time window, the information packet of one first response message includes index information for at least one random access signal, the index information being a random access signal indicating that the information packet is responding to the index information.

[0040] In this embodiment, a method for receiving a signal is further provided, and Figure 3 is a flowchart of a method for receiving a signal according to an embodiment of the present disclosure, and as shown in Figure 3, the flowchart includes the following step S302.

[0041] In step S302, the random access signals transmitted by the second node on the resources corresponding to each of the multiple target beams are received, and the multiple target beams are beams determined by the second node.

[0042] The entity that performs the above steps may be the first node described above, which may be a device having signal transmission and reception capabilities, such as a base station, or a module in a base station, or a network node capable of data transmission with a base station, or other processing equipment or processing unit having similar processing capabilities. Hereinafter, the above operations will be described using the example of a base station (this is merely an illustrative explanation, and in actual operation, other equipment or modules may perform the above operations), and the second node will be the aforementioned UE.

[0043] In the above embodiment, the second node can determine a plurality of target beams and, further, transmit a random access signal to the first node based on the resources corresponding to each of the plurality of target beams. In this way, it is possible to transmit a random access signal to the first node using resources that can transmit random access signals corresponding to each of the plurality of target beams. This avoids a situation where, if a failure occurs when only a resource corresponding to a single beam is used, it becomes impossible to transmit a random access signal to the first node. This solves the technical problem in related technologies where random access signals can only be transmitted using resources corresponding to a single beam in the random access process, and achieves the technical effect of being able to transmit random access signals using resources corresponding to each of the plurality of beams, thereby meeting communication demands such as extremely low latency, extremely high reliability, ultra-wide bandwidth, and high volume of access.

[0044] In the above embodiment, the multiple target beams may be the optimal beam determined by the second node from among the multiple beams, or they may be beams arbitrarily determined by the second node from among the multiple beams.

[0045] In an exemplary embodiment, the plurality of target beams are determined by the second node in at least one of the following ways: measuring a downlink signal and selecting the plurality of target beams based on the measurement results; selecting the plurality of target beams from stored beams; obtaining the plurality of target beams from a plurality of beams set by the first node; and selecting a target resource group from a plurality of set resource groups and selecting the plurality of target beams from a plurality of beams corresponding to the target resource group.

[0046] In an exemplary embodiment, the step of receiving random access signals transmitted by a second node on resources corresponding to each of a plurality of target beams includes the step of receiving the random access signals transmitted by the second node on a resource corresponding to a first beam, wherein the first beam is determined by the second node in such a manner as determining the transmit power for transmitting the random access signals on the target beams and determining the first beam from a plurality of the target beams based on the transmit power, and the number of the first beams is one or more and is less than or equal to the number of target beams.

[0047] In one exemplary embodiment, the second node determines the first beam from a plurality of target beams based on the transmission power, by determining the corresponding target beam whose transmission power is less than or equal to a first threshold as the first beam.

[0048] In an exemplary embodiment, the method further includes the step of receiving random access signals transmitted by a second node on resources corresponding to a plurality of target beams, the step of sending a first response message back to the second node based on the received random access signals, the first response message being for instructing the second node to send an uplink message based on the uplink channel resource configured by uplink channel configuration information in the first response message, the uplink message comprising at least one of first indication information indicating whether or not to use a first active beam, and identification information of a second node sending the uplink message, the first active beam being a target beam for the random access signals corresponding to the first response message, and the beam corresponding to the first response message being a second active beam.

[0049] In one exemplary embodiment, if the second node decides to stop using the first active beam based on the first indication information in the received uplink message, the transmission of a second response message to the second node on the resource corresponding to the second active beam is terminated; if the second node decides to use the first active beam based on the first indication information in the received uplink message, a second response message is transmitted to the second node on the resource corresponding to the second active beam, the second response message being a response message to the uplink message.

[0050] In one exemplary embodiment, upon receiving the uplink message, and if the first indication information contained in at least one of the uplink messages received within one time window indicates that the first active beam will no longer be used, the second node selects at least one first active beam from the first active beams that will no longer be used as indicated by the second node, and continues to send a second response message to the second node on the resource corresponding to the second active beam corresponding to the selected at least one first active beam, the second response message being a response message to the uplink message.

[0051] In one exemplary embodiment, the base station receives the uplink message transmitted by the second node on an uplink channel resource configured by uplink channel configuration information in one or more selected first response messages, the selected one or more first response messages being selected by the second node from the acquired first response messages. In this embodiment, the information packet of the first response message may be carried by multiple first response messages, and the base station may also receive an uplink message transmitted by a terminal that has selected an uplink resource configured by uplink channel configuration information in one or more first response messages from the acquired first response messages.

[0052] In one exemplary embodiment, a target downlink channel is transmitted to the second node indicating whether or not the second node should continue using the first active beam, and if it is indicated that the second node should not continue using the first active beam, the second node does not continue to detect a second response message which is a response message to the uplink message, and if it is indicated that the second node should continue using the first active beam, the second node continues to detect a second response message.

[0053] Clearly, the embodiments described above represent only a portion, not all, of the embodiments of this disclosure. The present disclosure will be described in detail below with reference to specific embodiments.

[0054] In a 5G NR system, a terminal receives a TRP (Transmit-Receive Point, a new term for base stations in 5G) synchronization signal / physical broadcast channel block (SSB), and the SSB can be transmitted in a multi-beam manner, meaning that SSB information can be transmitted in different beam directions. Figure 4 is a schematic diagram of different beam directions between a base station and a terminal according to an embodiment of this disclosure. Based on the received SSB, the terminal selects a beam direction corresponding to the SSB, further selects a random access channel resource corresponding to that beam direction, transmits a random access signal (preamble) on the PRACH resource, and initiates the random access process. The SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH).

[0055] Mapping of SSB and PRACH Occasions in 5GNR Systems: SSB stands for SS / PBCH block, which includes downlink synchronization signals (primary synchronization signal PSS and secondary synchronization signal SSS) and PBCH (physical broadcast channel, which carries MIB (Management Information Base) information). Since NR supports multiple beam transmissions, SSB also supports transmission in multiple beam directions.

[0056] A PRACH Occasion (PRACH Time-Frequency Resource, abbreviated as RO) is a time-frequency resource corresponding to the transmission period of a PRACH Preamble. Multiple PRACH Occasions may be present in the frequency domain at the same time.

[0057] In the random access process in NR, a correspondence must be established between PRACH occasions and SSBs; that is, one PRACH occasion may correspond to one SSB or to multiple SSBs, and these are all configured by the base station.

[0058] Technical means 1: In step 1, the UE transmits a random access signal (preamble) on the PRACH time-frequency resource corresponding to multiple beams (i.e., the aforementioned PRACH occasion), which is called Msg1 message transmission (corresponding to the random access signal).

[0059] The beam direction selected by the UE is obtained in at least one of the following ways: In Method 1, the UE measures / detects a Downlink signal / channel (which may be transmitted in different beam directions) and determines a set of beam directions selected by the UE. Based on the measurement / detection results of the Downlink signal / channel, the UE compares them to a threshold and determines the number of beam directions selected by the UE according to the following method. If the number of beams that satisfy the threshold requirement is N or greater, then N beam directions are selected from among them (the N beam directions may be the optimal N of RSRP (Reference Signal Receiving Power) / RSRQ (Reference Signal Receiving Quality) / RSSI (Reference Signal Strength Indicator) / SNR (Signal-to-Noise-Ratio), or any N). Otherwise, all beams that satisfy the threshold requirement are selected as the beam directions. Satisfying the threshold requirement includes the fact that the information such as RSRP / RSRQ / RSSI / SNR used to measure / detect the Downlink signal / channel is above the threshold.

[0060] In method 2, the UE selects N beam directions. These N beam directions may be N beam directions stored in the UE, or they may be N beam directions used when the UE previously accessed the system.

[0061] In method 3, TPR sets N beam directions for the UE based on DL information. In Method 4, when configuring PRACH resources, PRACH resources (including PRACH time-frequency resources and / or preamble resources on PRACH) are grouped, and each group of PRACH resources can support Msg1 transmission in multiple beam directions. If the UE selects one group of PRACH resources, it transmits Msg1 on the M beams corresponding to this group of PRACH resources.

[0062] In step 1-1, after the UE determines the beams according to step 1 above, if the transmission power required for the UE to transmit Msg1 in the beam direction exceeds a threshold, the beam will not be used to transmit Msg1.

[0063] In step 2, the TRP sends response information for Msg1 to the UE, which is called Msg2 (corresponding to the first response information above). The scheduling information of Msg2 is carried on the Downlink Control Information (DCI) in the Downlink Control Channel (Physical Downlink Control Channel, abbreviated as PDCCH). Msg2 is transmitted on the PDSCH (Physical Downlink Shared Channel). Msg2 contains one or more information packets, each containing index information for at least one preamble. The preamble index information indicates that the information packet is a response to the preamble of the index information.

[0064] In step 3, after sending Msg1, the UE detects the PDCCH where the scheduling information of Msg2 sent from the TRP is located within one time window, and then detects Msg2 based on the scheduling information loaded onto the DCI in the detected PDCCH. The UE assumes that it has detected K (where K is less than or equal to M) Msg2s (K is used here to represent Msg2 because the TRP cannot necessarily detect all of the preambles of the M beams) of the M beams sent to it from the TRP. For example, the index information of the K preambles in the K Msg2 information packets (the K Msg2 information packets are not necessarily loaded onto a single Msg2, but may be distributed across multiple Msg2s within the above time window) is all transmitted by the UE. Furthermore, the K information packets of Msg2 each contain resource allocation information for the PUSCH (Physical Uplink Shared Channel) channel used by the UE to transmit uplink messages, and these uplink messages are referred to as Msg3.

[0065] In step 4, the UE sends K1 Msg3 messages through the PUSCH channel indicated by K Msg2 information packets. The Msg3 messages are: (1) First indication information indicating that the UE will continue to use the beams direction, and (2) Identification information of the UE, including at least one of the following: The number of K1s is less than or equal to K. When the UE transmits Msg3, if the transmit power exceeds the threshold, Msg3 is not transmitted, and the corresponding beam direction is also abandoned by the UE.

[0066] In step 5, after receiving the Msg3 message sent by the UE, the TRP performs the following actions:

[0067] If Msg3 indicates that the UE does not use the beams direction, the TRP will not continue to send Msg4 (corresponding to the second response message above), which is a response message to Msg3, to the UE in the beams direction. Msg4 is carried by the PDSCH scheduled by the PDCCH, If Msg3 indicates that the UE will continue to use the beams direction, or if Msg3 does not contain the first indication information, the TRP will continue to send Msg4, which is the response information to Msg3, to the UE.

[0068] Technical means 2: This technical means is an extension of step 5 in technical means 1.

[0069] The extension of Step 5 is as follows: In step 5, after receiving the Msg3 message sent by the UE, the TRP performs the following actions:

[0070] The TRP sends a PDCCH to the UE, indicating in its DCI whether or not to abandon the beam direction. If the DCI instructs the UE to abandon the beam direction, the UE will not continue to detect subsequent Msg4 information. If the DCI instructs the UE to continue using the beam direction, the UE will continue to detect subsequent Msg4 information. If the DCI does not instruct the UE to continue using the beam direction, the TRP obtains the indication information contained in the resource allocation information of Msg4, that is, instructs the UE to decode the DCI, and determines that the resource allocation information of Msg4 is a valid value. In this case, the TRP decides to instruct the UE to continue using the beam direction.

[0071] Technical means 3: This technical means is an extension of step 5 in technical means 1.

[0072] The extension of Step 5 is as follows: In step 5, after receiving the Msg3 message sent by the UE, the TRP performs the following actions:

[0073] If the TRP detects a Msg3 message sent by the UE only in the unused beams direction indicated by the UE, the TRP will continue to send Msg4 messages to the UE in that beams direction. In the random access process, Msg3 is scheduled by the Msg2 information packet, but the Msg2 information packet contains only preamble index information, and the preamble is common to UEs using the same beams. Therefore, multiple UEs sending Msg3 using the same beams can cause collisions between Msg3 messages from multiple UEs, potentially preventing the TRP from detecting Msg3 in those beams, or conversely, detecting Msg3 in beams abandoned by the UE. To ensure the random access flow, the TRP can modify the UE's decision, i.e., continue using the beams direction to complete the random access flow.

[0074] In step 6, the UE continues to detect the PDCCH of the response message Msg4 for the K Msg3 messages, If the UE has not received a PDCCH in the beams direction that is not used as indicated by the UE, an action is taken to confirm that the beams direction is abandoned. If the UE receives a PDCCH in the unused beams direction indicated by the UE, and the DCI in the PDCCH contains confirmation information that the beams are not being used, the UE will cease to detect the PDCCH in the beams direction. If the UE receives a PDCCH in the unused beams direction indicated by the UE, and the DCI in the PDCCH contains information that the beams will continue to be used, the UE will continue to detect Msg4 messages based on the PDSCH scheduling information in the PDCCH. If the UE receives a PDCCH in the unused beams direction indicated by the UE, and the DCI in the PDCCH contains PDSCH scheduling information, and the scheduling information of the PDSCH is valid, the UE performs one of the following actions: continue detecting Msg4 messages based on the PDSCH scheduling information in the PDCCH.

[0075] Technical means 4: This technical means is an extension of steps 4-5 in technical means 1.

[0076] In step 3 (which corresponds to technical means 1), after sending Msg1, the UE detects within one time window the PDCCH where the scheduling information of Msg2 sent from the TRP is located, and then detects Msg2 based on the scheduling information placed on the DCI in the detected PDCCH. Assume that the UE has detected K (K is less than or equal to M) Msg2s sent from the TRP for the M beams it has sent itself (since the TRP cannot necessarily detect all of the preambles for the M beams, K is used here to represent Msg2), and for example, the index information of the K preambles in the K Msg2 information packets (the K Msg2 information packets are not necessarily placed in a single Msg2, but may be distributed across multiple Msg2s within the above time window) are all sent from the UE. Furthermore, the K information packets of Msg2 each contain resource allocation information for the PUSCH channel for the UE to transmit uplink messages, and these uplink messages are called Msg3.

[0077] The extension of step 4 above is as follows: In step 4, the UE receives information packets for Msg2 in K beam directions, selects K1 beam directions from which to send Msg3 messages. The scheduling information for the Msg3 messages is shown in the information packets for Msg2. Msg3 messages are not sent for a beam direction if at least one of the following conditions is met.

[0078] (1) When the UE transmits Msg3 in one beam direction, if the transmit power exceeds a threshold, the Msg3 will not be transmitted. (2) If the size of the Msg3 resource set in the Msg3 information packet does not meet the UE's requirements, the Msg3 will not be sent. (3) If the channel quality performance of the Msg2 message received by the UE for a beam's Msg1 does not meet the requirements, the corresponding Msg3 will not be sent.

[0079] The extension of step 5 described above is specifically as follows: In step 5, after receiving the Msg3 message sent by the UE, the TRP performs the following actions:

[0080] The TRP sends a PDCCH to the UE, indicating in its DCI whether or not to abandon the beam direction. If the DCI instructs the UE to abandon the beam direction, the UE will not continue to detect subsequent Msg4 information. If the DCI instructs the UE to continue using the beam direction, the UE will continue to detect subsequent Msg4 information. If the DCI does not instruct the UE to continue using the beam direction, the UE will retrieve the indication information contained in the resource allocation information of Msg4, that is, instruct the UE to decode the DCI and determine that the resource allocation information of Msg4 is valid. If the TRP determines that the resource allocation information of Msg4 is valid, the TRP decides to instruct the UE to continue using the beam direction.

[0081] Technical means 5: This technical means is an extension of step 3 in technical means 1.

[0082] In step 2 (which is the same as step 1-2 in technical means 1), the TRP sends response information for Msg1 to the UE, which is called Msg2. The scheduling information for Msg2 is carried on the downlink control information (DCI) in the downlink control channel (PDCCH). Msg2 is transmitted carried on the PDCCH. Msg2 contains one or more information packets, each containing index information for at least one preamble. The index information of the preamble is used to indicate that the information packet is a response to the preamble of the index information. Furthermore, when configuring PRACH resources, PRACH resources (including PRACH time-frequency resources and / or preamble resources on PRACH) are grouped, and each group of PRACH resources can support Msg1 transmission in multiple beam directions. If the UE selects one group of PRACH resources, it transmits Msg1 on the M beams corresponding to this group of PRACH resources.

[0083] The extension of step 3 above is as follows: In step 3, after sending Msg1, the UE detects a PDCCH sent from the TRP within one time window, and the DCI of the PDCCH contains the scheduling information of Msg2, which is the response information to Msg1. Within the time window, the UE detects the PDCCH, finds the preamble index it sent from the Msg2 message carried on the corresponding PDCCH, and continues to send Msg3 according to the Msg3 resource indicated in Msg2. Furthermore, the UE does not continue to detect PDCCHs sent from the TRP within the time window.
