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 the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided a method embodiment for 5G resource location determination, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
The process of a terminal device performing Random Access (RACH) in a wireless communication system such as LTE and 5G generally includes four steps:
step 101, a terminal device (UE) sends a random access preamble (msg.1), which is carried in a PRACH (physical random access channel), to a base station, and forms a C-RNTI (Cell-radio network temporary identifier) or a TC-RNTI (Cell-radio network temporary identifier).
Step 102, the base station sends a Random Access Response (RAR), namely msg.2, to the UE after detecting the random access preamble, where the RAR is carried in a PDCCH (Physical Downlink Control Channel) and a PDSCH (Physical Downlink Shared Channel), and at the same time, scrambles a CRC (Cyclic Redundancy Check) of a DCI (Downlink Control Information ) carried in the PDCCH in the msg.2 by using a C-RNTI or a TC-RNTI.
Step 103, the UE receives the random access response, and if an RNTI (radio network temporary identifier) in the random access response is the same as the C-RNTI or TC-RNTI used for CRC scrambling of the DCI in step 201, and/or a time domain position of an RO (RACH occupancy, random access Channel opportunity) in the msg.2 indicating that msg.1 is located is the same as a time domain position of an RO in which the UE sends msg.1, the UE is considered to receive the random access response of the UE, and sends an Uplink message, i.e., msg.3, on an Uplink resource of the response, which is borne in a PUSCH (Physical Uplink Shared Channel).
Step 104, the base station receives the uplink message of the UE, and returns a collision resolution message, namely msg.4, to the UE which has successfully accessed, and the message is carried in the PDSCH.
In some random access scenarios, contention access is not required, and a non-contention RACH access also exists, which specifically includes the following steps:
step 1011, the base station sends a proprietary C-RNTI formula to the UE, which is carried in the PDCCH.
Step 1012, the UE sends a random access preamble and the C-RNTI (Msg.1) to the base station, wherein the random access preamble and the C-RNTI are borne in the PRACH.
Step 1013, the base station sends a random access response, namely msg.2, to the UE after detecting the random access preamble, where the random access response is carried in the PDSCH.
With the increasing application scenarios of sparse, small and low-delay data transmission, the transmission of such data services needs to be satisfied, and the traditional 4-step RACH becomes a technical bottleneck due to the time delay introduced by the multi-step interaction between the UE and the base station.
Currently, a two-step random access procedure (2-step RACH) is proposed, which specifically includes the following steps:
step 201, the UE sends a random access preamble and data, i.e. msg.a, to the base station, which are carried in PRACH and PUSCH.
Step 202, the base station sends a random access response, i.e. msg.b, to the UE, which is carried in the PDSCH.
In the initial access process, the UE needs to send feedback information of msg.4/msg.b in the PDSCH through the PUCCH, that is, it carries ACK (Acknowledgement) or NACK (non-Acknowledgement) information in a Hybrid Automatic Repeat reQuest (HARQ), and after the UE correctly demodulates the msg.4/msg.b information, it feeds back the ACK information to the base station through the PUCCH, otherwise, if the msg.4/msg.b information is not successfully demodulated, it sends NACK information through the PUCCH.
Specifically, the PUCCH related configuration is configured by a parameter "PUCCH-ConfigCommon" in the System Information Block 1 (SIB 1, system Information Block 1), and the range of values thereof is "0 to 15", and configurations corresponding to different values are shown in fig. 1. Fig. 1 defines 16 sets of resources, where Index denotes the lowest physical resource block Index of PUCCH; the PUCCH format represents the format of the PUCCH; firstymbol represents the starting symbol position of the PUCCH; numberrofssymbols represents the number of symbols of the PUCCH to be transmitted; PRB offset represents an offset amount of a physical resource block; setofinitial CS Indexes denotes an initial cyclic shift index.
Fig. 2 is a method for determining a location of a 5G resource according to an embodiment of the present invention, applied to a terminal device, as shown in fig. 2, the method includes the following steps:
In this step, the terminal types include, but are not limited to, the following terminal types of terminal devices: rel.15 terminal devices, rel.17Redcap terminal devices, rel.18RedCap terminal devices.
In this step, the signaling includes configuration information indicating that the terminal devices of different terminal types determine the parameter of the lowest physical resource block index occupied by the uplink control channel.
And 303, determining the lowest physical resource block index according to the configuration information.
Through the steps, the purpose that the PUCCH of the lightweight terminal always falls into the initial uplink bandwidth can be achieved by reporting the terminal type and receiving the parameters configured according to different terminals, so that the technical effect of reliable transmission of uplink control information of the PUCCH is achieved, and the problem that the used PUCCH cannot transmit the uplink control information outside the effective bandwidth due to the Rel.18RedCap terminal using the existing resource position determining method is solved.
Specifically, step 301 includes:
step 3011 demodulates system information block 1 (SIB 1).
In this step, the system information block 1 is a broadcast message periodically transmitted by the base station, and includes an initial uplink bandwidth portion for uplink signal transmission.
Step 3012, if the system information block 1 includes at least three initial uplink bandwidth portions not greater than 5MHz, receiving a signaling including the parameter a sent by the base station.
In this step, the base station configures different configuration information for terminal devices of different terminal types, stores the configuration information into the system information block 1, and periodically transmits the configuration information, and for a rel.18redcap terminal, the SIB1 defaults a cell under the base station to allow the rel.18redcap terminal to access to a target cell. If the system information block 1 includes at least three initial uplink bandwidth portions not greater than 5MHz, only the initial uplink bandwidth portions of the rel.15 terminal, the rel.17red cap terminal and the rel.18erecap terminal are not greater than 5MHz, so that it can be considered that there is inevitably one rel.18erecap terminal, and therefore, the signaling including the parameter a in the configuration information of the base station is directly received, the subsequent lowest physical resource block index calculation is performed according to the parameter a, the resource position within the effective bandwidth of the PUCCH is obtained, and the transmission of uplink control information is ensured.
After receiving the signaling containing parameter A, P needs to be calculated firstThe index number of the UCCH frequency domain resource satisfies the range of r being more than or equal to 0 PUCCH ≦ 15, in particular, characterized by the following formula:
wherein r is PUCCH An index number representing the PUCCH frequency domain resource; n is a radical of CCE Indicates the number of Control Channel Elements (CCEs) in the received PDCCH; n is CCE,0 An index indicating reception of a first CCE in the PDCCH channel; delta of PRI And taking the value of the PUCCH resource indication field.

It should be noted that, the capabilities of the terminal devices of different terminal types are different, for a general NR system supporting eMBB (enhanced mobile broadband), the highest transmission rate may exceed 100mbps, the rate supported by a rel.17redcap terminal is between 10Mbps and 100Mbps, the rate supported by a rel.18eredcap terminal is between 100kbps and 10Mbps, and for narrowband Internet of Things (NB-IoT, narrow Band Internet of Things) technology, the supported rate is less than or equal to 100kbps. In terms of the maximum supported bandwidth, the rel.15 terminal can support a bandwidth of 100MHz at FR1 (Frequency Range 1), the rel.17red cap terminal can support a bandwidth of 20MHz at most, and the rel.18redcap terminal can support a bandwidth of 5MHz at most. For example, if the two terminal devices of the different terminal types are a rel.17redcap terminal and a rel.18eredcap terminal, respectively, the value of the third parameter is the ratio of the maximum bandwidth portions supported by the rel.17 terminal and the rel.18 terminal, that is, 20/5=4.
