It will be appreciated by those skilled in the art that without certain details, the disclosure equally be can be implemented.In some instances, for Method, means, element and circuit well known to those skilled in the art are not described in detail, in order to highlight the purport of the disclosure.

Fig. 1 is a kind of flow chart of uplink transmission resource acquisition methods shown according to an exemplary embodiment.Such as Fig. 1 institute Show, the method may include:

Step 100, the time-frequency that the one or more that network side issues is used for Physical Random Access Channel PRACH transmission is obtained Resource RO is configured and is provided with the associated time-frequency for transmitting uplink data of each competition lead code for corresponding to RO in RO configuration Source PO configuration；

Step 101, it is configured according to the associated PO of the RO configuration and RO configuration that get, determines present terminal equipment The available RO of the RACH transport-type of use, the RACH transport-type include 2 step RACH transmission and 4 step RACH transmission；

Step 102, the lead code that selection is transmitted on determining RO executes uplink on the corresponding PO of lead code of selection Data transmission.

In the embodiments of the present disclosure, terminal device may include such as mobile phone, smartwatch, tablet computer, notebook electricity The equipment such as brain, the embodiment of the present disclosure to the type of terminal device without limitation.

Network side can usually indicate in certain radio coverage area, and information transmitting is carried out between mobile terminal Transceiving believe radio station.Network side can for example including BS (base station, Base Station) or RRU (Remote Radio Unit, Radio Remote Unit) etc., the embodiment of the present disclosure to the specific form of network side without limitation.

In the related technology, terminal device is when using 4 step RACH transmission access network side, and 4 steps of usual and base station interaction should For the interactive process terminal device sensitive to delay requirement, time delay is too long, in order to reduce terminal equipment access network side when Prolong, propose 2 step RACH transmission, terminal device may include: to the MsgA that network side uploads in the first step that 2 step RACH are transmitted Terminal device is in 4 step RACH transmission in the Msg (message) 1 of first step upload and the Msg3 uploaded in third step；Network side is 2 Second step in step RACH transmission is to the MsgB that terminal device the issues second step that may include: network side in 4 step RACH transmission The Msg4 that the Msg2 and the 4th step issued is issued.

Under normal conditions, terminal device can be transmitted when needing to access network side using 2 step RACH transmission or 4 step RACH, In the related technology, network side can be respectively 2 step RACH transmission and the dedicated RO of 4 step RACH transmission configurations or lead code, so as to For network side according to when receiving lead code, the lead code that effective district tap receives is by using 2 step RACH transmission terminal equipment It uploads, or uploaded using 4 step RACH transmission terminal equipment, but 4 step RAHC transmission and 2 step RACH are transmitted shared The scene of RO and lead code, if the terminal device using 2 step RACH and the terminal device using 4 step RACH transmission are identical It can not determine that the lead code is by using 2 step RACH after having selected identical preamble transmissions, network side to receive lead code on RO Terminal device send, or by using 4 step RACH terminal device send, network side is in this case, it will usually It is transmitted in corresponding RAR (random access response window, random access response) window in 4 step RACH and sends Msg2, and When being next decoded to the data sent using the terminal of 2 step RACH transmission, transmits in corresponding response window and send out in 2 step RACH Send MsgB.Since MsgB contains Msg2, if not sending this lead code, base using the terminal device of 4 step RACH transmission The Msg2 sent stand just without effect, this has resulted in the waste of network side signal resource.If in addition network side also needs blind The data in lead code corresponding resource that solution receives, if it is leading not send this using the terminal device of 2 step RACH transmission Code and data, then the blind solution of network side is really nonsensical.

Generally, in 4 step RACH transmission processes, terminal device has sent random access request on ascending resource RO After Msg1, accidental access response message Msg2 is sent on downlink resource.Terminal device after leading code, is matched before sending in base station The available PDCCH of first of the random access response search space and control resource set instruction set (Physical Downlink Control Channel, Physical Downlink Control Channel) occur position start 4 step RACH accidental access response message windows, prison It listens and is disappeared with the downlink resource 4 step RACH random access responses of reception of the scrambled PDCCH instruction accidental access response message of RA-RNTI Breath.

In 2 step RACH transmission processes, terminal device can send lead code on ascending resource RO, and associated by the RO PO on send data after, base station configuration 2 step RACH random access response search spaces and control resource set instruction The position that first available PDCCH occurs starts 2 step RACH accidental access response message windows, receives 2 step RACH random access Response message.

To TDD (time division duplex, Time Division Duplexing) mode, in different uplink and downlink timeslot configurations, 4 The available RO for walking RACH occurs in many configurations under the starting position n-th (N is positive integer) code symbol after RO is exactly Row time slot.The search space period for being generally configured to accidental access response message is 1 time slot, so descending time slot can open Dynamic random access response window.For 2 step RACH transmission mechanisms, terminal device sends lead code on RO, will also be associated by the RO PO transmitting data after, the random access response window of 2 step RACH could be started, therefore should have uplink before descending time slot Resource distribution is the corresponding associated PO resource of RO, otherwise, needs to configure PO resource on the ascending resource after downlink resource, make It is very long at MsgA propagation delay time, the original design intention of 2 step RACH is violated, so needing to solve the available RO configuration of 2 step RACH.

As an example of the present embodiment, network side can determine one or more for physics according to default rule The running time-frequency resource RO of random access channel PRACH transmission is configured and is associated with each competition lead code for corresponding to RO in RO configuration The running time-frequency resource PO for transmitting uplink data configure, (such as network side can be according to the terminal device of access network side Quantity, determines PO configuration associated by RO configuration corresponding with the quantity and RO configuration, and disclosure example determines network side The rule of PO configuration associated by RO configuration and RO configuration is without limitation), network side can match determining one or more PO It sets the PO configuration associated with RO configuration for example to issue by way of broadcast to terminal device, the available network of terminal device The associated PO configuration of the one or more RO configuration and RO configuration that side issues.

In a kind of example, RO configuration includes being used to indicate the RO to configure whether corresponding RO is suitable for 2 step RACH transmission Instruction information, Fig. 2 is a kind of flow chart of uplink transmission resource acquisition methods shown according to an exemplary embodiment.Such as figure Shown in 2, the difference between Fig. 2 and Fig. 1 is, step 101 may include: step 200, according to the instruction information that RO is configured, really Surely it is suitable for the available RO for the RACH transport-type that present terminal equipment uses.

For example, RO, which is configured, can for example carry whether the RO for identifying the RO configuration instruction is suitable for present terminal equipment The RACH transport-type of use.Terminal device can transmit the lead code of selection on determining RO, in the lead code pair of selection Transmitting uplink data is executed on the PO answered.

For example, network side can transmit available RO with 2 step RACH of separate configurations, and can be transmitted with 4 step RACH of separate configurations The instruction information of available RO, RO configuration can serve to indicate that the RO configures whether corresponding RO is exclusively used in 2 step RACH transmission or 4 Walk RACH transmission.For network side when receiving lead code, the RACH transport-type that the RO that the lead code is transmitted in confirmation is applicable in is (only 4 step RACH transmission or only 2 step RACH transmission), and under the RACH transport-type that can be applicable in for the RO for transmitting the lead code Signaling.

For another example, network side, which can configure 2 step RACH transmission and 4 step RACH transmission, can share RO, and can be with 4 step of separate configurations RACH transmits available RO, (it should be noted that due to network side in the second step in 2 step RACH transmission under terminal device The MsgB of hair may include: the Msg4 that network side second step issues in 4 step RACH transmission Msg2 and the 4th step are issued, because This, the RO that terminal device is got, which configures corresponding RO, can be adapted for 4 step RACH transmission, in this way, it is only necessary to distinguish energy Enough it is suitable for the RO of 2 step RACH transmission, terminal device selection can be expanded when terminal device is transmitted using 4 step RACH The range of RO increases data transmission efficiency) the instruction information of RO configuration can serve to indicate that whether the RO configures corresponding RO special It is transmitted for 4 step RACH, or both can be used for 4 step RACH transmission, can be used for 2 step RACH transmission.Network side is receiving When lead code, the RACH transport-type that the RO of the lead code is applicable in is transmitted in confirmation, and (4 step RACH transmission and 2 step RACH transmission are equal Can use, or only 4 step RACH transmission is available), and can be issued for the RO for transmitting the lead code RACH transport-type being applicable in Signaling.

Step 300, if the RACH transport-type that present terminal equipment determines is 2 step RACH transmission, instruction is selected to believe One or more RO that breath instruction is suitable for 2 step RACH transmission are used as candidate RO；

Step 301, the RO for selecting associated downlink signal quality to meet preset condition from the candidate RO, as current The RO for the RACH transport-type that terminal device uses.

As an example of the present embodiment, network side, which can configure 2 step RACH transmission and 4 step RACH transmission, to be shared RO, and 4 step RACH of separate configurations transmits available RO, terminal device can determine the RACH transport-type used for 2 steps In the case that RACH is transmitted, the one or more RO for selecting the instruction information instruction in RO configuration to be suitable for 2 step RACH transmission make For candidate RO, terminal device can detecte downlink signal quality associated by candidate RO, for example, down going wave associated by candidate RO The signal quality of beam, and associated downlink signal quality is selected to meet preset condition (for example, signal quality value is greater than default threshold Value) RO, as present terminal equipment use RACH transport-type RO.

In one possible implementation, signal quality can for example including it is following any one or more: terminal is set The standby RSRP value (Reference Signal Received Power, Reference Signal Receiving Power) for receiving reference signal is whole RSRQ value (Reference Signal Received Quality, the Reference Signal Receiving of end equipment reception reference signal Quality) or terminal device receive reference signal SINR (Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio).The embodiment of the present disclosure does not limit the particular content of the signal quality of cell It is fixed.

In one possible implementation, the instruction information includes: the instruction parameter of the every class configuration item of static table, is used In when the RO configuration using 4 step RACH carries out 2 step RACH transmission, indicate to be suitable in time domain RO corresponding to such configuration item The time domain RO of 2 step RACH.

In the embodiments of the present disclosure, static table can be expressed as the mapping table for recording RO configuration, and table 1 is one The example of static table, network side can issue the configuration of the RO including static table index to terminal device, and terminal device can basis Static table index determines the corresponding configuration item of static state table index (for example, static table index is 78, before available 78 is corresponding It is 7 that first RO, which is located at the starting symbol in slot s lot, in leading code format " A1 ", each subframe, and each RO time domain length is Have continuous 3 RO in 2 symbol, each slot), it can determine according to every class configuration item parameter and can be used for 2 step RACH biography Defeated RO.For example, the RO can be determined as before the next descending time slot of RO there are when the ascending resource of available configuration PO It can be used for the RO of 2 step RACH transmission.As shown in table 1, the corresponding instruction of static index 78 ginseng is 1 and 2, then can indicate RACH weeks First RO and second RO in phase can be used for 2 step RACH transmission.It should be noted that can according to need what selection was applicable in Indicate parametric form, the embodiment of the present disclosure does not limit this.
