All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that "/" in this context means "or", for example, A/B may mean A or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.
It should be noted that, for the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present application, the terms "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions or actions, and those skilled in the art can understand that the terms "first", "second", and the like do not limit the quantity and execution order. For example, the first beam and the second beam are used to distinguish between the different beams, rather than to describe a particular order of the beams.
It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
It should be noted that in the embodiments of the present application, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that the intended meaning is consistent when the difference is not emphasized. The meaning of "a plurality" in the embodiments of the present application means two or more.
It should be noted that the signal transmission method provided by the implementation of the present invention can be applied to the RACH-less handover scenario.
The RACH-less switching comprises the following steps:
step 1: in the mobility process of a terminal device (such as UE), the terminal device may send an uplink signal in a target cell according to sending resource information of a data channel configured by a network device. The network device may indicate a maximum Time Advanced (TA) value of an uplink signal sent by the terminal device in the target cell, for example, the TA value is the same as the source cell, or the TA value is "0". Specifically, the RACH-less handover may be that the terminal initiates a target Cell handover, or the terminal initiates a Secondary Cell Group (SCG) handover.
Step 2: after receiving Contention resolution identity (contentionresolution id) information scheduled by a Cell radio network Temporary identity (C-RNTI) sent by a network device, a terminal device considers that the mobility process is successful. For example, the target cell handover initiated by the terminal device is successful, or the SCG change initiated by the terminal device is successful.
For example, in the case that a random access is initiated to the network device during terminal device mobility, the terminal device may send a random access request message to the network device in the PUSCH.
Specifically, the signal transmission method implemented by the present invention may be applied to a process in which the terminal device and the network device transmit signals on multiple beams, for example, a process in which the terminal device receives downlink signals from the network device in multiple beams.
For example, after the terminal device transmits the random access request message to the network device in the PUSCH, the network device may transmit the random access response message to the terminal device in a plurality of beams, such that the terminal device receives the random access response message from the network device in the plurality of beams.
However, in the prior art, only in a process of Random access initiated by a terminal device through a Physical Random Access Channel (PRACH), the terminal device is supported to select a specific beam corresponding to a PRACH resource; and receiving the random access response information from the network equipment through a downlink channel corresponding to the specific beam under the condition that the network equipment sends the random access response information to the terminal equipment in the multi-beam. In the process that the terminal device initiates random access through the PUSCH, the terminal device does not select to transmit the random access request message on a specific beam, so that the subsequent terminal device cannot determine on which beam of the multiple beams the network device transmits the random access response message. As a result, the terminal device may not successfully receive the random access response message sent by the network device.
In view of the foregoing problems, embodiments of the present invention provide a signal transmission method, device, and system, where a terminal device may determine a first beam; and sending a first uplink signal to the network device on a first resource of the first resource set corresponding to the first beam, where the first uplink signal is an uplink signal carried on the data channel. In this way, the network device may receive a first uplink signal transmitted by the terminal device on a first beam, and select the first beam from the multiple beams, so as to transmit the first downlink signal to the terminal device on a second resource corresponding to the first beam (i.e., a second beam); further, the terminal device is enabled to successfully receive the first downlink signal from the first beam. Therefore, the probability of successfully receiving the downlink signal in the multi-beam after the terminal equipment adopts the data channel to send the uplink signal to the network equipment can be improved.
That is, in the process that the terminal device initiates random access through the PUSCH, the terminal device may send a random access request to the network device on the PUSCH resource corresponding to the first beam; enabling the network equipment to select a first beam from the plurality of beams and send a random access response message to the terminal equipment on a downlink resource corresponding to the first beam; further, the terminal device is enabled to select a first beam from the plurality of beams, and successfully receive the random access response message on the first beam. Therefore, the problem that the terminal equipment cannot successfully receive the random access response message sent by the network equipment and cannot successfully access the network equipment under the condition that the network equipment sends the random access response message to the terminal equipment in a plurality of beams in the prior art can be solved.

Fig. 2 shows a schematic flow chart of a signal transmission method according to an embodiment of the present invention, and as shown in fig. 2, the signal transmission method may include steps 201 and 202:
step 201: the terminal device determines a first beam.
The terminal device may transmit signals with the network device on a plurality of beams, and the terminal device may select one beam from the plurality of beams to determine to obtain the first beam.
In particular, a beam may be identified by its corresponding one or more signals, which may include at least one of: channel State Information reference signals (CSI-RS), Synchronization Signal Blocks (SSBs) (SSBs may also be referred to as ssblocks).
Step 202: the terminal device sends a first uplink signal to the network device on a first resource of a first resource set corresponding to the first beam, where the first uplink signal is an uplink signal carried on a data channel.
In one example, after step 202, the network device may receive a first uplink signal from the terminal device on a first resource in a first set of resources corresponding to the first beam.
It is to be understood that the first resource is one of one or more resources included in the first set of resources, and the one or more resources in the first set of resources may each be a data channel transmission resource, i.e., an uplink resource.
For example, in the embodiment of the present invention, the data channel may be a PUSCH; the resources (e.g., the first resources) in the first set of resources may be PUSCH resources; the first beam may be a beam corresponding to a PUSCH resource.
For example, in the process that the terminal device initiates random access to the network device, the first uplink signal may be a random access request message carried on a PUSCH resource.
Optionally, in this embodiment of the present invention, the terminal device may determine the first beam according to information issued by the network device. Specifically, the step 201 may be implemented by the step 201-1:
step 201-1: the terminal device determines a first beam according to target configuration information configured by the network device, wherein the target configuration information is at least used for indicating a first corresponding relationship, and the first corresponding relationship is used for indicating that the first beam corresponds to the first resource set.
It is understood that, in an example, as shown in fig. 3, the signal transmission method provided by the embodiment of the present invention may include the steps of 201a:
step 201a, the network device configures target configuration information for the terminal device.
The target configuration information is at least used to indicate a first corresponding relationship, where the first corresponding relationship is used to indicate that the first beam corresponds to the first resource set, and a first uplink signal on a first resource in the first resource set is an uplink signal carried on a data channel.
For example, the step 201a may be performed before the step 202.
Optionally, the target configuration information at least includes a correspondence between a first beam and a first identifier, where the first identifier is used to indicate a first resource set; wherein the first identifier is any one of the following: a resource position of a resource in the first resource set, a Hybrid Automatic Repeat request (HARQ) process identifier corresponding to the resource in the first resource set, and an identifier indicating configuration information of the first resource set.
Specifically, the following embodiments take three application scenarios as examples:
in a first application scenario, a first identifier is a resource location of a resource in a first resource set;
in a second application scenario, the first identifier is an HARQ process identifier corresponding to a resource in the first resource set;
in a third application scenario, the first identifier is an identifier of configuration information of the first set of resources.
In the first application scenario and the second application scenario, the network device configures a set of configuration information indicating a resource set for each terminal device in the communication system. In a third application scenario, the network device configures multiple sets of configuration information indicating resource sets for each terminal device in the communication system.
Optionally, the configuration information indicating the first resource set includes resources in the first resource set.
It can be understood that, in the case that the first set of resources corresponds to the first beam, the terminal device determines the first beam, that is, the terminal device may transmit the first uplink signal to the network device on a resource (e.g., the first resource) in the first set of resources. Further, when the network device receives the first downlink signal, it may be determined that the first downlink signal is carried on a first resource in a first resource set corresponding to the first beam. In this way, the subsequent network device may send the downlink signal to the terminal device on the downlink resource corresponding to the first beam.
Optionally, the first resource is any one resource in a first resource set, the first resource set is any one of at least one resource set, and the at least one resource set is a resource set indicated by the uplink grant configuration information.
The uplink authorization configuration information may be configured for the terminal device by the network device.
For example, a set of configuration information (e.g., ulGrantConfig-1) configured by the network device for the terminal device may include multiple pieces of PUSCH time-frequency resource information, such as multiple pieces of uplink grant configuration information (i.e., multiple U L grants), and each U L grant may include information such as a U L grant resource allocation period, a U L grant starting resource position, and a number of HARQ processes.
The process of configuring the target configuration information for the terminal device by the network device is any one of the following two examples:
in an example, in a handover procedure of a terminal device, a network device may configure, through a Radio Resource Control (RRC) message, a corresponding relationship between a U L grant for accessing a target cell and a beam, that is, the target configuration information, to the terminal device.
In another example, a network device may trigger a terminal device to initiate a random access process by sending Downlink Control Information (DCI) information, where the DCI information indicates a corresponding relationship between a U L grant and a beam, that is, the target configuration information, and the terminal device selects a resource carrying random access request information to send the random access request information according to the target configuration information configured by the network device, and may receive a random access response message on the beam.
It can be understood that, before the terminal device sends the first uplink signal on the first resource in the first resource set corresponding to the first beam, the terminal device may first select the first resource from the first resource set.
Optionally, the first resource includes any one of: the resource allocation method includes the steps of selecting a resource from a first resource set, selecting a resource from a second resource set, selecting a resource from a plurality of resources from the first resource set, and selecting a resource from the plurality of resources.
The most recently available resource in the first resource set may be a resource which is triggered by the terminal device to select from the first resource set, and is then a next available "control information transmission resource".
Wherein the continuous resource may include at least one of: time contiguous resources (e.g., resources of adjacent slots specified by the protocol), frequency contiguous resources (e.g., resources of slots of adjacent physical resource blocks specified by the protocol), time and frequency contiguous resources (e.g., resources of adjacent slots and adjacent physical resource blocks specified by the protocol).
Optionally, the first set of resources includes at least one of: at least one resource corresponding to a specific time domain position and at least one resource corresponding to a specific frequency domain position.
It is to be understood that, in the first application scenario, the first set of resources includes at least one of resources corresponding to at least one specific time domain location and resources corresponding to at least one specific frequency domain location; in the second application scenario or the third application scenario, the resources in the first resource set are not necessarily the resources corresponding to the specific time domain position or the resources corresponding to the specific frequency domain position.
For example, the resource corresponding to a specific time domain position may be a PUSCH resource with a specific period (e.g., a period of 10 ms).
For example, the resource corresponding to a specific frequency domain position may be a PUSCH resource corresponding to a specific Physical Resource Block (PRB), a PUSCH resource corresponding to a specific frequency point, or a PUSCH resource corresponding to a specific cell.
Optionally, the target configuration information is used to indicate a plurality of corresponding relationships, each corresponding relationship is a corresponding relationship between one beam and the resource set, and the first corresponding relationship is one of the plurality of corresponding relationships. The step 202a can be realized by the step 202 b:
step 202 b: and the terminal equipment determines a first beam according to the target configuration information and the target rule, wherein the first beam is the beam of which the measured value is greater than or equal to the measurement threshold value in the plurality of beams indicated by the target configuration information.
Wherein the target rule comprises: beams are selected for which the measurement value is greater than or equal to the measurement threshold value.
That is, the terminal device may select a first beam from among the plurality of beams indicated by the target configuration information to determine the first beam.
The measured value of the beam may be a measurement result of a signal in the beam. Illustratively, the measurement of a beam is a measurement of Reference Signal Received Power (RSRP) of the SSB in that beam. The measurement Threshold is ssbRSRP-Threshold of the measurement result for the RSRP. Of course, the measurement value of the beam may be other measurement results, and is not limited herein.
Optionally, in an example, in combination with fig. 2, as shown in fig. 4, after the step 202, a step 203 may further be included:
step 203: and the terminal equipment receives the first downlink signal from the network equipment on a second resource corresponding to the second beam, wherein the first beam is the same as the second beam.
The first downlink signal is a signal corresponding to the first uplink signal, a terminal device specific downlink data channel signal, or a terminal device specific downlink control channel signal.
Accordingly, the network device may send the first downlink signal to the terminal device on the second resource corresponding to the second beam.
Wherein, the second resource is a downlink resource.
For example, in the case that the first downlink signal is a signal corresponding to the first uplink signal, the first downlink signal may be scheduling information of a random access response message (e.g., a PDCCH corresponding to the RAR) or a random access response message (e.g., a PDSCH corresponding to the RAR). Specifically, the first downlink signal may be feedback information for the first uplink signal, such as C-RNTI scheduling information carried on the PDCCH corresponding to the second beam.
For example, the terminal device specific downlink data channel signal may be a signal carried by a terminal device data channel, such as a signal carried by a PDSCH corresponding to terminal device data sent by a subsequent network device.
For example, the terminal device specific downlink control channel signal may be scheduling information of a terminal device data channel, such as a signal carried by a PDCCH corresponding to a PDSCH corresponding to subsequent terminal device data transmission.
The RAR is a Random Access Response (Random Access Response), the PDCCH is a Physical Downlink Control Channel (Physical Downlink Control Channel), and the PDSCH is a Physical Downlink Shared Channel (Physical Downlink Shared Channel).
Further optionally, the first downlink signal may include multiple items of a signal corresponding to the first uplink signal, a terminal device specific downlink data channel signal, or a terminal device specific downlink control channel signal.
Optionally, the second beam may correspond to a second resource set, where the second resource set includes a second resource. Similarly, the process of the network device selecting the second resource from the second resource set may refer to the above description of the terminal device selecting the first resource from the first resource set.
Optionally, step 204 and step 205 may be further included after step 203:
step 204: the terminal device receives target indication information from the network device, wherein the target indication information is used for indicating that the second beam corresponding to the first downlink signal is updated to be the third beam.
Accordingly, the network device may send the target indication information to the terminal device.
Step 205: and the terminal equipment updates the first target corresponding relation stored in the terminal equipment into a second target corresponding relation according to the target indication information.
The first target corresponding relationship is a corresponding relationship between the second beam and the first downlink signal, and the second target corresponding relationship is a corresponding relationship between the third beam and the first downlink signal.
Optionally, when the terminal device updates the first target corresponding relationship stored in the terminal device to the second target corresponding relationship, the resource subsequently carrying the downlink signal may be the same as or different from the second resource.
It is to be understood that, before the terminal device receives the target indication information, the terminal device receives the downlink signal on the resource (e.g., the second resource) corresponding to the second beam, e.g., receives the first downlink signal on the second resource corresponding to the second beam.
According to the signal transmission method provided by the embodiment of the invention, the terminal equipment can determine the first wave beam; and sending a first uplink signal to the network device on a first resource of the first resource set corresponding to the first beam, where the first uplink signal is an uplink signal carried on the data channel. In this way, the network device may receive a first uplink signal transmitted by the terminal device on a first beam, and select the first beam from the multiple beams, so as to transmit the first downlink signal to the terminal device on a second resource corresponding to the first beam (i.e., a second beam); further, the terminal device is enabled to successfully receive the first downlink signal from the first beam.
