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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for allocating uplink shared channel resources according to an embodiment of the present disclosure, where the method for allocating uplink shared channel resources according to the embodiment includes the following steps:
step 101: resource configuration information is received.
In step 101, resource configuration information is received, where the resource configuration information includes 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. And configuring the preamble sequence configuration information and the PUSCH configuration information by the base station. The device for receiving resource configuration information may be, for example, a terminal, where a corresponding relationship between preamble sequences and PUSCH configuration information is set in the terminal, and each preamble sequence has at least one PUSCH configuration information corresponding thereto. When one preamble sequence is mapped to a plurality of types of PUSCH configuration information, one type of PUSCH configuration information is selected from the PUSCH configuration information according to a rule set by a system. The PUSCH configuration information comprises 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 corresponding relationship between preamble sequences and PUSCH configuration information, and the corresponding relationship may be set by the base station, so that each preamble sequence has at least one type of PUSCH configuration information corresponding thereto. 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 set of preamble sequence and PUSCH resource is selected according to the PUSCH carrying 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 equipment of the preamble sequence and the PUSCH bearing information selects a PUSCH resource configuration set which can meet the information requirement in the PUSCH configuration information according to the PUSCH bearing information amount, namely the PUSCH resource configuration amount is not lower than the PUSCH bearing information amount, and then selects the preamble sequence set according to the corresponding relation between the PUSCH configuration and the preamble sequence. And further selecting a preamble sequence from the preamble sequence set, selecting a PUSCH resource according to the corresponding relation between the preamble sequence and the PUSCH configuration information, and sending the selected preamble sequence and the PUSCH bearing information. The sequence of selecting the preamble sequence and the PUSCH resource configuration may be adjusted in the implementation process, for example, a corresponding relationship between the preamble sequence and the PUSCH carrying information amount range is set or the PUSCH resource configuration amount is one, the preamble sequence may be selected first according to the PUSCH carrying information amount, and one resource configuration may be selected according to the corresponding relationship between the preamble sequence and the PUSCH configuration information.
Further, the transmission device for the preamble sequence and the PUSCH carrying information may be, for example, a terminal including a first configuration unit and a transmission unit. After receiving the resource configuration information, the first configuration unit selects a preamble sequence configuration and a PUSCH resource in the resource configuration information according to the PUSCH bearing information amount, selects the preamble sequence according to the corresponding relationship between the PUSCH configuration information and the preamble sequence, and selects the preamble sequence configuration information according to the preamble sequence. And finally, sending the preamble sequence and the PUSCH bearing information to the sending unit, and sending the information by the sending unit.
In the two steps of the uplink shared channel resource configuration method provided in this embodiment, the PUSCH configuration information includes one or more PUSCH resource configurations. The configuration amount of the PUSCH resource may be obtained by calculating a size of a transmission packet according to time domain resource configuration information, frequency domain resource configuration information, DMRS configuration information, MCS configuration information, frequency hopping configuration information, and the like of the PUSCH configuration information.

For example, the PUSCH configuration information 2 stepracch-PUSCH-Config includes a plurality of ResourceConfig _ n (n ═ 1,2, …), and each ResourceConfig _ n (n ═ 1,2, …) corresponds to a configuration amount of a PUSCH resource. And when the configuration quantity of the PUSCH resource is one, the configuration quantity of the PUSCH resource is not less than the maximum value of the PUSCH bearing information quantity. And when the configuration quantity of the PUSCH resources is more than one, each group of leader sequences corresponds to a range of the PUSCH bearing information quantity. One kind of leader sequence can correspond to the configuration amount of one kind of PUSCH resource, and one kind of leader sequence in each group of leader sequences corresponds to one kind of PUSCH bearing information amount range. Furthermore, the configuration quantity of each PUSCH resource corresponds to a PUSCH bearing information quantity range. The configuration quantity of each PUSCH resource is not less than the upper limit of the corresponding PUSCH bearing information quantity range, and multiple PUSCH bearing information quantity ranges can also correspond to the same configuration quantity of the 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) th group of 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 nth group of preamble sequences may be selected correspondingly. The PUSCH bearer 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 PUSCH bearer information amount range corresponding to the nth group of preamble sequences has the same upper and lower limits, that is, requiredTBsizemin _ n is requiredTBsizemax _ n. At this time, the packet N (N ═ 1,2, …, N) of the preamble sequence corresponds to a PUSCH bearer traffic range [ requiredTBsizemin _ N, requiredTBsizemax _ N ], and the packet N (N ═ 1,2, …, N) of one preamble sequence corresponds to one PUSCH bearer traffic. And further selecting the configuration amount of the PUSCH resources according to the corresponding relation between the preamble sequences and the configuration amount range of the PUSCH resources, namely that one or more preamble sequences in a preamble group N (N-1, 2, …, N) correspond to one or more types of PUSCH configuration information, so that the size of the configuration amount of the PUSCH resources is not lower than the upper limit of the PUSCH bearing information amount range corresponding to the preamble sequences.
