Background
In the random access procedure based on the contention mode defined in the existing 4G and 5G, at least four signaling interactions between the terminal and the base station are required, which is called 4-step RACH. The method comprises the following four transmissions: the first time the terminal sends Msg1 to the base station, the Msg1 is the terminal to select the leading sequence according to the set rule in the standard 38.321 or 36.321, and the leading sequence is used for the base station to carry out TA estimation and the like; the second time the base station sends Msg2 to the terminal, the Msg2 is the random access response of Msg1, which contains the leading sequence identification, TA, the up-going authorization of the terminal sending Msg3 to the base station, TC-RNTI, etc.; the third time of terminal sends Msg3 to the base station, when the terminal reads the preamble sequence identifier corresponding to Msg1 in Msg2, the content of Msg3 is related to the event triggering the random access process; and the fourth time the base station transmits Msg4 to the terminal, the Msg4 is a response for resolving the competition conflict, and when the Msg4 detected by the terminal contains relevant identification information in the corresponding Msg3, the random access is considered to be successful. With further research of technology, in order to reduce signaling overhead and random access delay, a new random access procedure is added by considering to simplify a random procedure based on a contention mode, and interaction of signaling between a terminal and a base station is only needed at least twice, which is called 2-step RACH.

Because the events triggering RACH are different, the size of the transmission content of the corresponding PUSCH of the MsgA in the 2-step RACH is generally different, so that the number of physical resources required by the PUSCH corresponding to the MsgA is different, and the base station needs to consider the resource requirement of the corresponding PUSCH in the MsgA under different RACH triggering events when configuring the PUSCH scheduling-free resources. For the 2-step RACH, a PUSCH scheduling-free resource allocation solution corresponding to the MsgA needs to be designed to meet the transmission resource number requirements of different MsgAs. At present, a solution for configuring PUSCH scheduling-free resources corresponding to MsgA is not formed in the standard technical solution.

Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a flowchart of an uplink shared channel resource allocation method provided in an embodiment of the present application, where the uplink shared channel resource allocation method provided in the embodiment includes the following steps:
step 101: resource configuration information is received.
In step 101, resource configuration information is received, the resource configuration information including preamble sequence configuration information and PUSCH configuration information.
In this embodiment, the sending device of the resource configuration information may be, for example, a base station. The configuration information of the preamble sequence and the configuration information of the PUSCH are configured by the base station. The device for receiving the resource configuration information may be, for example, a terminal, where a correspondence between a preamble sequence and PUSCH configuration information is set in the terminal, where each preamble sequence has at least one PUSCH configuration information corresponding to the preamble sequence. When one preamble sequence is mapped to a plurality of kinds of PUSCH configuration information, one kind of PUSCH configuration information is selected from the PUSCH configuration information according to a rule set by a system. The PUSCH configuration information includes at least one of time domain resource configuration information, frequency domain resource configuration information, DMRS configuration information, MCS configuration information, and frequency hopping configuration information.
As another embodiment of the present application, the resource configuration information further includes a correspondence between the preamble sequences and PUSCH configuration information, where the correspondence may be set by the base station, so that each preamble sequence has at least one PUSCH configuration information corresponding to the preamble sequence. And the terminal acquires the corresponding relation by receiving the resource configuration information.
Step 102: and sending the preamble sequence and the PUSCH bearing information.
In step 102, at least one group of preamble sequences and PUSCH resources are selected according to the PUSCH bearer information amount within the preamble sequence configuration information and PUSCH configuration information range. And sending the preamble sequence and the PUSCH bearing information.
In this embodiment, the set of preamble sequences and PUSCH resources is one preamble sequence and one PUSCH resource configuration corresponding to the preamble sequence. After receiving the resource configuration information, the sending device of the preamble sequence and the PUSCH carrying information selects a PUSCH resource configuration set which can meet information requirements in the PUSCH configuration information according to the PUSCH carrying information quantity, namely, the PUSCH resource configuration quantity is not lower than the PUSCH carrying information quantity, and then selects the preamble sequence set according to the correspondence between the PUSCH configuration and the preamble sequence. And further selecting one leader sequence from the leader sequence set, selecting one PUSCH resource according to the corresponding relation between the leader sequence and the PUSCH configuration information, and sending the selected leader sequence and the PUSCH bearing information. The sequence of selecting the preamble sequence and PUSCH resource configuration may be adjusted in the implementation process, for example, the correspondence between the preamble sequence and the PUSCH load information amount range is set, or the PUSCH resource configuration amount is one type, the preamble sequence may be selected according to the PUSCH load information amount, and one type of resource configuration may be selected according to the correspondence between the preamble sequence and the PUSCH configuration information.
Further, the transmitting device of the preamble sequence and PUSCH bearer information may be, for example, a terminal including a first configuration unit and a transmitting unit. And after receiving the resource configuration information, selecting the preamble sequence configuration and the PUSCH resource in the resource configuration information according to the PUSCH bearing information quantity by the first configuration unit, selecting the preamble sequence according to the corresponding relation between the PUSCH configuration information and the preamble sequence, and selecting the preamble sequence configuration information according to the preamble sequence. And finally, the preamble sequence and the PUSCH bearing information are sent to the sending unit and sent by the sending unit.
In the two steps of the uplink shared channel resource allocation method provided in this embodiment, the PUSCH allocation information includes one or more PUSCH resource allocation. The allocation amount of the PUSCH resources may be obtained by calculating the size of the transmission packet according to time domain resource allocation information, frequency domain resource allocation information, DMRS allocation information, MCS allocation information, frequency hopping allocation information, and the like of the PUSCH allocation information. The PUSCH bearing information quantity is obtained according to the size of the MAC PDU which needs to be transmitted in the RACH triggering event.
Further, the preamble sequences are grouped, so that each group of preamble sequences corresponds to a range of PUSCH load information quantity. The configuration quantity of the PUSCH resources selected according to the PUSCH bearer information includes one or more cases. Selecting a PUSCH resource according to the PUSCH configuration information, wherein the configuration quantity of the PUSCH resource is one type and is not smaller than the maximum value of the PUSCH bearing information quantity; or the configuration quantity of the PUSCH resources is more than one, and the configuration quantity of each PUSCH resource is not less than the upper limit of the corresponding PUSCH bearing information quantity range.
For example, the PUSCH configuration information 2stepRACH-PUSCH-Config includes a plurality of resourceconfig_n (n=1, 2, …), and each resourceconfig_n (n=1, 2, …) corresponds to a configuration amount of PUSCH resources. When the configuration amount of the PUSCH resources is one, the configuration amount of the PUSCH resources is not less than the maximum value of the PUSCH bearer information amount. When the configuration quantity of the PUSCH resource is larger than one, each group of the preamble sequences corresponds to a range of the PUSCH bearing information quantity. Since one preamble sequence may correspond to one allocation amount of PUSCH resources, one preamble sequence of each group of preamble sequences corresponds to one PUSCH load information amount range. Further, the configuration quantity of each PUSCH resource corresponds to a PUSCH bearing information quantity range. The configuration amount of each PUSCH resource is not less than the upper limit of the corresponding PUSCH load information amount range, and the multiple PUSCH load information amount ranges can also correspond to the same configuration amount of PUSCH resources.
For example, the preamble sequences are divided into N groups, the PUSCH bearer information amount range corresponding to the N (n=1, 2, …, N) group preamble sequences is [ requiredtbsizemin_n, requiredtbsizemax_n ], and when the PUSCH bearer information amount range corresponding to the PUSCH bearer information is within [ requiredtbsizemin_n, requiredtbsizemax_n ], the preamble sequence of the N group may be selected correspondingly. The PUSCH-bearing information amount range corresponding to the preamble sequence includes a special case where the upper and lower limits of the range are the same, for example, the upper and lower limits of the PUSCH-bearing information amount range corresponding to the nth group of preamble sequences are the same, i.e., requiredtbsizemin_n=requiredtbsizemax_n. At this time, the packet N (n=1, 2, …, N) of the preamble sequence corresponds to the PUSCH bearer information amount range [ requiredtbsizemin_n, requiredtbsizemax_n ], and the packet N (n=1, 2, …, N) of one preamble sequence corresponds to one PUSCH bearer information amount. And further selecting the configuration quantity of the PUSCH resources according to the corresponding relation between the preamble sequences and the configuration quantity range of the PUSCH resources, namely, one or more preamble sequences in the preamble group N (n=1, 2, …, N) correspond to one or more PUSCH configuration information, so that the configuration quantity of the PUSCH resources is not lower than the upper limit of the PUSCH bearing information quantity range corresponding to the preamble sequences.
Fig. 2 is a flowchart of an uplink shared channel resource allocation method including a detection step, and the uplink shared channel resource allocation method provided in this embodiment includes the following steps:

In step 201, resource configuration information is received, the resource configuration information including preamble sequence configuration information and PUSCH configuration information.

In step 202, at least one group of preamble sequences and PUSCH resources are selected according to the PUSCH bearer information amount within the preamble sequence configuration information and PUSCH configuration information range. And sending the preamble sequence and the PUSCH bearing information.
Step 203: and detecting the preamble sequence and the PUSCH bearing information.
In step 203, the preamble sequence and PUSCH bearer information are detected. The receiving device of the preamble sequence and PUSCH carrying information may be, for example, a base station comprising a second configuration unit and a reception detection unit.
And after receiving the preamble sequence and the PUSCH bearing information, the base station configures the base station to send resource configuration information required by detection to the receiving detection unit through the second configuration unit, wherein the resource configuration information comprises the preamble sequence configuration information and the PUSCH configuration information. Further, the method also comprises a corresponding relation between the preamble sequence and the PUSCH configuration information.

In this embodiment, the sending device of the resource configuration information may be, for example, a base station. The configuration information of the preamble sequence and the configuration information of the PUSCH are configured by the base station. The device for receiving the resource configuration information may be, for example, a terminal, where a correspondence between a preamble sequence and PUSCH configuration information is set in the terminal, where each preamble sequence has at least one PUSCH configuration information corresponding to the preamble sequence.
