Technical Field

Background

In the related art, random access (Random Access Channel, RACH) includes: a first type of random access and a second type of random access. In the first type of random access, 2 times of information interaction are required to be performed between the terminal device and the network device, so the first type of random access is also called a two-step random access (2-step RACH). In the second type of random access, 4 times of information interaction are required to be executed between the terminal equipment and the network equipment; thus, the second type of random access is also called four-step random access (4-steps RACH). When the first type of random access and the second type of random access coexist, in order to realize effective management of resources, how the network equipment allocates resources for the terminal equipment, no effective solution exists at present.

Detailed Description

So that the manner in which the features and techniques of the embodiments of the present invention can be understood in more detail, a more particular description of the invention, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the present invention.

Before explaining the resource management method provided by the embodiment of the invention in detail, the random access will be briefly explained. In the NR system, random access includes contention-based random access and non-contention-based random access according to a random access scheme. The random access includes a first type of random access and a second type of random access according to the random access type. The first type of random access and the second type of random access are briefly described below, respectively.

The second type of random access process is shown in fig. 1, and includes the following four steps:

in step S101, the terminal device sends a random access Preamble to the network device through message 1 (message 1, msg 1).

The terminal equipment sends the selected Preamble on the selected PRACH time domain resource; the network device can estimate the uplink Timing and the uplink authorization required by the terminal device to transmit the MSG3 according to the Preamble.

In step S102, after detecting that the terminal device sends the Preamble, the network device sends a random access response (Random Access Response, RAR) message to the terminal device through the MSG2 to inform the terminal device of uplink resource information that can be used when sending the MSG3, and allocates a temporary radio network temporary identifier (Radio Network Tempory Identity, RNTI) to the terminal device, and provides time advance command for the terminal device.

After the terminal equipment sends MSG1, opening an RAR window, and detecting PDCCH in the RAR window; the detected PDCCH is scrambled by the RA-RNTI, and the calculation formula of the RA-RNTI is as follows:

RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id；

as can be seen from the above formula, the RA-RNTI is related to PRACH time-frequency resources.

The RAR is schematically shown in FIG. 2, and includes a sub header (subheader), RAPID, payload, an uplink (UpLinkUL) grant (grant) and a Temporary C-RNTI; the format of the subheader is shown in fig. 3a and 3b, wherein BI is used to indicate the backoff time of the retransmission MSG 1;

step S103, after receiving the RAR message, the terminal equipment sends MSG3 in the uplink resources specified by the RAR message.

Wherein the Msg3 message is mainly used to inform the network device what event the RACH procedure is triggered by. For example, if it is an initial random access event, the terminal device ID and establishment cause are carried in MSG 3; in case of an RRC reestablishment event, the terminal equipment identity and establishment cause of the connection state will be carried in MSG3.

Meanwhile, a contention conflict in which the ID carried by MSG3 may be is resolved in step S104.

In step S104, the network device sends MSG4 to the terminal device, where the MSG4 includes a contention resolution message, and allocates uplink transmission resources for the terminal device.

When the terminal equipment receives the MSG4 sent by the network equipment, the terminal equipment detects whether the terminal equipment specific temporary identifier sent by the terminal equipment in the MSG3 is contained in the contention resolution message sent by the base station, if so, the terminal equipment random access process is successful, otherwise, the random process is considered to be failed, and the terminal equipment needs to initiate the random access process from the first step again.

Another effect of MSG4 is to send radio resource control (Radio Resource Control, RRC) configuration messages to the terminal device.

Contention conflict resolution includes two modes; the first mode is as follows: if the terminal device carries a cell radio network temporary identity (Cell Radio Network Tempory Identity, C-RNTI) in MSG3, MSG4 is scheduled with a C-RNTI scrambled physical downlink control channel (Physical Downlink Control Channel, PDCCH). The first way is: if the terminal equipment does not carry the C-RNTI in the MSG3, if the terminal equipment is initially accessed, the MSG4 uses the PDCCH dispatching scrambled by the TC-RNTI; the conflict is resolved by the terminal device receiving the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) of MSG4, matching the common logical channel (Common Control Channel, CCCH) service data unit (Service Data Unit, SDU) in the PDSCH.

The message contents carried by MSG1, MSG2, MSG3 and MSG4 in the second type of random access are shown in table 1.

TABLE 1

The RACH process is completed by four information interactions with the terminal device through the network device, resulting in a long time delay of the RACH process; in order to solve the problem of prolongation during RACH procedure, a first type of random access is proposed, and the processing flow of the first type of random access is shown in fig. 4, which includes the following steps:

step S201, the terminal device sends the MSGA to the network device.

The MSGA consists of Preamble and payload. Optionally, the Preamble is the same as the Preamble in the second type of random access, and the Preamble is transmitted on PRACH resources; the information carried by the payload is the same as the information in MSG3 in the second type of random access, such as RRC signaling when the RRC is in idle state, and C-RNTI when the RRC is in connected state, and the payload may be transmitted by a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

The network device may receive the results of the MSGA as follows: first, the network device successfully decodes one or more preambles; second, the network device successfully decodes one or more preambles and one or more payload.

In step S202, the terminal device receives the MSGB sent by the network device.

Optionally, the MSGB includes contents of MSG2 and MSG4 in the second type of random access.

For the above-mentioned case that the first type random access and the second type random access coexist, if a separate RACH resource is allocated for the first type random access, although the problem of sharing the resource with the second type random access can be avoided, fragmentation of the network resource is increased. Therefore, when the first type random access and the second type random access are required to share the PRACH resource, although the utilization rate of the resource can be improved, after the network device detects the Preamble, the network device cannot distinguish whether the Preamble is sent by the terminal device in the first type random access or the terminal device in the second type random access.

Based on the above-mentioned problems, the present invention provides a resource management method, and the resource management method of the embodiments of the present application may be applied to various communication systems, for example: global system for mobile communications (Global Svstem of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) systems, general packet radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) systems, LTE frequency division duplex (Frequency Division Duplex, FDD) systems, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication Svstem, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication systems, or 5G systems, and the like.

Taking the communication system 100 shown in fig. 5 as an example, the communication device may include the network device 110 and the terminal device 120 with communication functions, where the network device 110 and the terminal device 120 may be the specific devices described above, which are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

An optional processing flow of the resource management method applied to the first terminal device provided in the embodiment of the present invention, as shown in fig. 6, includes the following steps:

step S301, when the first type random access is successful, the first terminal equipment transmits first data based on a first uplink grant indicated by a received first MAC PDU; and when the first type of random access fails, the first terminal equipment transmits second data based on the target uplink grant indicated by the received second MAC PDU.

It may be appreciated that in the embodiment of the present invention, before the first terminal device transmits the first data or the second data, it needs to determine whether the first type random access is successful.

In specific implementation, the first terminal device determines whether the first type random access is successful by: the first terminal device sends a first message to the network device, wherein the first message at least comprises: the method comprises the steps of leading code Preamble and second data, wherein the second data is payload; then, the first terminal equipment starts a first window, and the length of the first window is longer than that of a RAR window of a second type of random access, so that the network equipment has longer time for decoding payload; the first terminal device determines that the first type random access is successful when detecting that the first MAC PDU comprises a contention resolution identifier (Contention Resolution ID) matched with the first message in the first window; the first MAC PDU will indicate a first uplink grant for the first terminal device; the first terminal equipment transmits first data by utilizing a first uplink grant, wherein the first data comprises a BSR and/or an RRC message; the RRC message includes at least one of: RRC setup complete messages, RRC resume complete messages and RRC reestablishment complete messages.

And when the first terminal equipment does not detect that Contention Resolution ID matched with the first message is included in the first MAC PDU in a first window, determining that the first type of random access fails. At this time, the first terminal device transmits the second data based on the target uplink grant indicated by the second MAC PDU. In this way, the first terminal equipment for the first type random access and the second terminal equipment for the second type random access can share RACH resources, and when the first terminal equipment fails in the first type random access, the first terminal equipment retransmits payload based on the uplink grant with later time domain resources in two uplink grants sent to the second terminal equipment by the network equipment so as to perform the first type random access; therefore, the requirement of receiving the MSG2 by the second terminal equipment in the second type of random access by utilizing the earlier uplink grant of the time domain resource in the two uplink grants sent by the network equipment is met, the time delay of retransmitting the payload by the first terminal equipment in the first type of random access is reduced, and the transmission efficiency is improved.

Optionally, when the first terminal equipment is in an idle state or a non-activated state, the first terminal equipment monitors a PDCCH scrambled by the RA-RNTI; when the first terminal equipment is in a connection state, the second terminal equipment monitors the PDCCH scrambled by the RA-RNTI and the PDCCH scrambled by the C-RNTI.

The first MAC PDU and the second MAC PDU are described separately below.

The first MAC PDU includes Contention Resolution ID and payload; optionally, the first MAC PDU may further include a rapid. The first MAC PDU is sent to the first terminal device after the network device detects the Preamble through the PDCCH scheduling scrambled by the RA-RNTI or the C-RNTI.

The second MAC PDU is sent to the second terminal device after the network device detects the Preamble through the PDCCH scheduling scrambled by the RA-RNTI. In the embodiment of the invention, the second MAC PDU at least comprises two structures; a schematic structure of a second MAC PDU, as shown in fig. 7, for the same Preamble received by the network device, the second MAC PDU includes: the first MAC sub PDU and the second MAC sub PDU; the first MAC sub PDU and the second MAC sub PDU may be two consecutive MAC sub PDUs or two discontinuous MAC sub PDUs; the first MAC sub-PDU comprises a first RAPID and a first MAC RAR, and the second MAC sub-PDU comprises a second RAPID and a second MAC RAR; the second uplink authorized time domain resource indicated by the second MAC RAR and the third uplink authorized time domain resource indicated by the first MAC RAR have a first time interval, and the second uplink authorized time domain resource position is after the third uplink authorized time domain resource position, where the third uplink authorization is used for the second terminal to transmit third data.

In a specific implementation, the network device may indicate, through a first MAC subheader of a second MAC PDU, whether two MAC sub PDUs including the same rapid ID exist in the second MAC PDU. Optionally, when the value of the first bit in the first MAC sub-header is the first value, it is indicated that there are two MAC sub-PDUs including the same rapid in the second MAC PDU. As shown in fig. 8, the network device uses one of the R bits in the E/T/R/BI MAC subheader to indicate that the second MAC PDU includes two MAC RARs of the same rapid. If the bit value corresponding to the R bit is set to 0, it indicates that the second MAC PDU does not include the MAC RAR of the two same rapid IDs; at this time, the first terminal device may directly ignore the decoding following the second MAC PDU without decoding each rapid. Optionally, when setting the R bit to 1, the network device may use a reserved BI value, such as index14 or index15, for the BI field; at this time, after receiving the MAC subheader of R bit 1, the second terminal device determines, according to the configured BI value of index14 or index15, that the back off time is 0ms, without affecting the second type random access performed by the second terminal device.

In some embodiments, the first terminal device detects a MAC RAR scheduled by the network device through a PDCCH scrambled by the RA-RNTI within a first window, and indicates a rapid sent by the terminal device within the MAC RAR, and the first terminal device ignores the first MAC RAR. And if the first terminal equipment determines that the first type of random access fails, the first terminal equipment determines the second uplink grant indicated by the second MAC RAR as a target uplink grant, and transmits second data by using the target uplink grant.

Another structure of the second MAC PDU is shown in fig. 9, and the second MAC PDU includes, for the same Preamble received by the network device: a third MAC sub PDU; the third MAC sub PDU includes: a third RAPID, a third MAC RAR, and a fourth MAC RAR; the fourth time domain resource of the fourth uplink grant indicated by the fourth MAC RAR and the fifth time domain resource of the fifth uplink grant indicated by the third MAC RAR have a second time interval, and the time domain resource location of the fourth uplink grant is after the time domain resource location of the fifth uplink grant, where the fifth uplink grant is used for the second terminal device to transmit third data. And when the fourth uplink grant is used for the first type random access failure, the first terminal equipment is used for transmitting the target uplink grant of the first data.

In an implementation, the network device may indicate, through a second MAC subheader of the second MAC PDU, whether there is two MAC RARs corresponding to one RAPID in one MAC sub PDU. Optionally, when the second MAC subheader indicates that there is no two MAC RARs corresponding to one RAPID in any one MAC sub PDU in the second MAC PDU, the first terminal device does not process the second MAC PDU.

In the embodiment of the present invention, the above-described alternative structure based on the second MAC PDU shown in fig. 7 and 9 is different from the alternative structure of the MAC PDU in the related art as shown in fig. 12; in the MAC PDU shown in fig. 10, one rapid corresponds to only one MAC RAR.

In the embodiment of the present invention, the first type of random access is 2-step random access (2-step RACH), and the second type of random access is 4-step random access (4-step RACH). Correspondingly, the first message is MSGA in the 2-step RACH, and the second message is MSGB in the 2-step RACH; the second data is payload carried in MSGA; the third data is the data carried in MSG3 in 4-step RACH, such as terminal equipment identifier and establishment cause (establishment cause) carried in MSG3 at the time of initial random access, or terminal equipment identifier and establishment cause in connection state carried in MSG3 at the time of RRC reestablishment.

Taking 2-step RACH as an example, the first terminal device uses the uplink grant allocated by the network device to the first terminal device to transmit the first data as shown in fig. 11. Taking 2-step RACH as an example, the first terminal device uses the uplink grant on the second RAR allocated by the network device to the second terminal device to transmit the second data as shown in fig. 12.

In the above embodiment, when the first type of random access fails, the first terminal device uses the uplink grant on the second RAR allocated by the network device to the second terminal device to transmit the second data. In other embodiments, when the first type of random access fails, the first terminal device acknowledges the 2-step RACH failure after the end of the first window, and retransmits the MSGA.

An optional process flow of the resource management method applied to the network device provided in the embodiment of the present invention, as shown in fig. 13, includes the following steps:

step S401, the network device sends a first MAC PDU and a second MAC PDU; the first uplink grant indicated by the first MAC PDU is used for transmitting first data by the first terminal equipment when the first type random access is successful; and the target uplink grant indicated by the second MAC PUD is used for transmitting second data by the first terminal equipment when the first type random access fails.

In the embodiment of the present invention, the descriptions for the first MAC PDU and the second MAC PDU are the same as those for the first MAC PDU and the second MAC PDU in the embodiment of the resource management method applied to the first terminal device, and are not repeated here.

In some embodiments, the method further comprises:

In step S402, when the network device receives the first data transmitted by the first terminal device and the first terminal device does not receive the second MAC RAR, the network device recovers the second uplink grant.

Here, when the network device receives the first data transmitted by the first terminal device, it characterizes that the first terminal device succeeds in switching to a first target cell corresponding to a target network device based on a first type of random access, that is, the first terminal device no longer needs a target uplink grant provided in the second MAC RAR; thus, the network device recovers the target upstream grant in order to assign the target upstream grant to other terminal devices.

In order to implement the above-mentioned resource management method applied to the first terminal device, the embodiment of the present invention further provides a first terminal device, where a schematic structural diagram of the first terminal device 500 is shown in fig. 14, and includes:

In an alternative embodiment, the first sending unit 502 is further configured to send a first message to the network device, where the first message includes at least: preamble and the second data.

In an alternative embodiment, the first terminal device 500 further includes:

a first processing unit 503, configured to determine that the first type of random access is successful when it is detected that Contention Resolution ID matched with the first message is included in the first MAC PDU within a first window; and determining that the first type of random access fails when Contention Resolution ID matched with the first message is not detected in the first MAC PDU in the first window.

In some alternative embodiments, the second MAC PDU comprises: the first MAC sub PDU and the second MAC sub PDU; the first MAC sub PDU comprises a first RAPID and a first MAC random access response RAR, and the second MAC sub PDU comprises a second RAPID and a second MAC RAR; the second uplink authorized time domain resource indicated by the second MAC RAR and the third uplink authorized time domain resource indicated by the first MAC RAR have a first time interval, and the second uplink authorized time domain resource position is after the third uplink authorized time domain resource position, where the third uplink authorization is used for the second terminal device to transmit third data. Optionally, the first MAC sub-header of the second MAC PDU is configured to indicate whether two MAC sub-PDUs including the same rapid exist in the second MAC PDU. And when the value of the first bit in the first MAC sub-header is a first value, representing that two MAC sub-PDUs with the same RAP ID exist in the second MAC PDU. Optionally, the target uplink grant is the second uplink grant.

In an alternative embodiment, when the first MAC sub-header indicates that there are no two MAC sub-PDUs including the same RAP ID in the second MAC PDU, the first processing unit 503 does not process the second MAC PDU.

In other alternative embodiments, the second MAC PDU comprises a third MAC sub PDU;

the third MAC sub PDU includes: a third RAPID, a third MAC RAR, and a fourth MAC RAR; the fourth time domain resource of the fourth uplink grant indicated by the fourth MAC RAR and the fifth time domain resource of the fifth uplink grant indicated by the third MAC RAR have a second time interval, and the time domain resource location of the fourth uplink grant is after the time domain resource location of the fifth uplink grant, where the fifth uplink grant is used for the second terminal device to transmit third data. Optionally, the target uplink grant is the fourth uplink grant.

Optionally, the second MAC sub-header of the second MAC PDU is configured to indicate whether one RAPID in one MAC sub-PDU exists in the second MAC PDU corresponds to two MAC RARs.

In an alternative embodiment, when the second MAC sub-header indicates that there is no two MAC RARs corresponding to one RAPID in any one MAC sub-PDU in the second MAC PDU, the first processing unit 503 does not process the second MAC PDU.

In the embodiment of the invention, the first MAC PDU is scheduled by a PDCCH scrambled by RA-RNTI or C-RNTI. And the second MAC PDU is scheduled by the PDCCH scrambled by the RA-RNTI.

In the embodiment of the present invention, the first MAC PDU further includes a rapid.
