Specific embodiment

In the following specific embodiments, numerous specific details are set forth, to provide to the saturating of theme claimed Thorough understanding.It will be understood by those skilled in the art, however, that can practice without these specific details claimed Theme.In other cases, well-known method, process, component and/or circuit are not described in.

Referring now to fig. 1, the process for being used for random access competition-based according to one or more embodiments will be discussed Diagram.In the example of fig. 1, it is standardized according to third generation cooperative partner program (3GPP) long term evolution (LTE), four operating process 100 can be used for initial random access competition-based.In the first operation 114, user equipment (UE) 110 by selecting at random A preamble signature is selected, sends Physical Random Access Channel (PRACH) in uplink (UL), which can permit Evolution node B (eNB) 112 estimates the delay between eNB 112 and UE 110, for subsequent UL timing adjustment.The 5th In generation (5G), newly eats dishes without rice or wine in (NR) standard, and eNB 112 may include gNB 112, but the range of theme claimed is unlimited In this.Then, in the second operation 116, eNB feeds back random access response (RAR), carries and adjusts for uplink timing 122 timing advance (TA) command information and the uplink transmitted for the uplink in third operation (L2/L3 message) 118 Road approval.For UE 110 it is contemplated that receiving RAR in time window, the starting and ending of the time window can pass through system information block (SIB) it configures.Finally, the contention resolution message for being sent to UE 110 from eNB 112 can occur at operation 120.

Referring now to Fig. 2, it will discuss according to the processes for being used for uncompetitive random access of one or more embodiments Diagram.It, can in order to reduce random access time delay for certain scenes (downlink traffic including switching and restoring UE 110) To request UE 110 to execute uncompetitive random access procedure 200, this can be ordered by physical downlink control channel (PDCCH) Enable triggering.Specifically, at operation 210, dedicated PRACH preamble signature is distributed to UE 110 by eNB 112, which can Except the preamble set for random access competition-based.Then, random access preamble is sent eNB by UE 110 112.It is noted that uncompetitive random access procedure terminates at the RAR message of operation 214.

Referring now to Fig. 3, believed discussing according to the random access in the perfect reciprocity scene of one or more embodiments The diagram of road process.As mentioned above, in the case where perfect reciprocity, UE 110 can be from can newly eat dishes without rice or wine with best 5G (NR) node B (gNB) sends (Tx) wave beam or beam reference signal (BRS) or SS block antenna port (AP) associated time or frequency The 5th generation (5G) Physical Random Access Channel (PRACH) resource is selected in rate PRACH resource.In one or more embodiments, Beam reference signal (BRS) can include but is not limited to the synchronization signal that the measurement of (Tx) wave beam is sent for downlink (DL) (SS) block, such as primary synchronization signal (PSS), secondary synchronization signal (SSS) or Physical Broadcast Channel (PBCH) or a combination thereof, and The range of theme claimed is without being limited thereto.

An example of RACH process in the case where perfect reciprocity is shown in Fig. 3.Downlink (DL) wave beam Or the relevance over time or over frequency between AP and corresponding PRACH resource is that cell is specific, and can be used as and be A part signaled for information of uniting, so that each DL Tx wave beam has dedicated association PRACH in uplink (UL) Resource.Alternatively, can for example based on group index or notation index, pre-define beam index (that is, BRS resource index) with The one-to-one or many-one relevance for example in time, frequency and/or sequence domain between PRACH resource.In any situation Under, before initiating RACH process, UE 110 should know this relevance at the idling mode.In the example depicted in fig. 3, In the time slot #0 indicated by 310, UE 110 is measured based on BRS to be received power and determines best gNB Tx wave beam.Such as Fig. 3 institute Show, for UE#1, the best Tx wave beam of gNB 112 is located at BRS wave beam group #0 and third orthogonal frequency division multiplexing (OFDM) symbol 312.According to correlation rule, UE 110 can be correspondingly in associated PRACH resource (that is, in the time slot #5 indicated 316 In 3rd PRACH time slot 314) send PRACH.

In order to increase random access capacity, UE 110 can be randomly chosen a frequency resource and transmit for PRACH.Such as Shown in Fig. 3, UE 110 can choose PRACH frequency resource #1 and transmit for PRACH.Alternatively, UE 110 can be at least partly Ground be based on potential message size (it is to be available for the data of transmission plus MAC header, optionally adds MAC control element) and The path loss that BRS based on optimum beam is measured suitably is selected from the associated available PRACH resource set of best Tx wave beam Select PRACH resource.More specifically, if message payload size is greater than the threshold value A with signaled, and if path loss is small In threshold value B, then UE 110 should be selected from the first PRACH group.Otherwise, UE 110 can be selected from the 2nd PRACH group Select one.

In one or more embodiments, reciprocity offset can be defined as I_reciprocity, can serve to indicate that non- Offset between ideal reciprocity and perfect reciprocity.Based on the offset, eNB 112 can configure one group of threshold value, to allow UE 110 use selected wave beam, are based on I_reciprocityDeviant come automatically export for PRACH transmission levels of repetition L. In one embodiment, levels of repetition L may refer to the number that PRACH is sent, but the range of theme claimed It is without being limited thereto.In one embodiment, can by higher via 5G Master Information Block (MIB), 5G system information block (SIB) or Via the threshold value of wireless heterogeneous networks (RRC) signal deployment three grades, for example, Threshold_0, Threshold_1 and Threshold_2.In one or more embodiments, higher may include the layer higher than physical layer, such as access in medium Control (MAC) layer, wireless spread-spectrum technology (RLC) layer, Packet Data Convergence Protocol (PDCP) layer, wireless heterogeneous networks (RRC) layer Or non-access (NAS) layer etc., but the range of theme claimed is without being limited thereto.In the feelings that threshold value is configured with by higher Under condition, UE 110 can export levels of repetition based on following formula:

As further expanding, I_reciprocityIt is specific to can be wave beam, and one group of threshold value can be configured by higher. In this case, for each particular beam, UE 110 can be by I_reciprocityIt is compared with threshold list, and determines and use Best Rx wave beam and corresponding number of repetition in PRACH transmission.

It should be noted that duplicate PRACH can be sent in a manner of continuously or discontinuously in the time domain.The time domain the case where Under, UE 110 can send PRACH L in resource corresponding with L optimum beam reference signal (BRS) antenna port (AP) Secondary, wherein L can be configured by higher via MIB or SIB or RRC signaling, or be determined as noted above. In view of that can define the one-to-one resource associations in the time domain between BRS antenna port and PRACH resource, UE 110 can To export corresponding time resource to transmit for PRACH.

In addition, same PRACH preamble signature can be used in UE 110, this can permit gNB 112 and executes combination to improve Detection performance.Specifically, UE 110 can be randomly chosen a PRACH preamble signature, and leading using selected PRACH Signature carries out subsequent PRACH transmission.Alternatively, UE 110 can be randomly chosen that a PRACH is leading, this can for each transmission To reduce collision probability.

In order to allow gNB 112 to identify, UE 110 is in non-ideal reciprocity conditions or perfect reciprocity conditions, non- Under ideal reciprocity conditions private resource can be distributed for UE 110.Particularly, this dedicated PRACH resource and in perfect reciprocity Property under for UE 110 resource can with when subassembly be multiplexed.In addition, under non-ideal reciprocity and perfect reciprocity The division of this group of private resource for UE 110 can be it is predetermined, or by higher via MIB, SIB or RRC believe It enables to configure.

It in one example, can be the reserved signature of PRACH, time or the frequency money of UE 110 under non-ideal reciprocity One or more of source, to send PRACH.In addition it is possible to use based on time division multiplexing (TDM), frequency division multiplexing (FDM) and/ Or the combination of the multiplexing scheme of code division multiplexing (CDM) is used for UE's 110 under non-ideal reciprocity and perfect reciprocity to separate Resource.

In another example, the preamble signature for each PRACH transmission can be different.Preamble signature can divide It is two groups: group A and group B.Group A indicates that current PRACH resource is determined by best DL beam index.Group B indicates that the PRACH is provided Source is determined by other DL beam index.Group A and the preamble signature organized in B should be one-to-one mappings.UE 110 can be with The preamble signature being randomly chosen in group A, the then preamble signature in selection group B, the preamble signature one-to-one mapping is into group A That preamble signature of selection.Therefore, gNB 112 is it is known which wave beam is best DL wave beam for UE 110, and is made RAR is sent with the DL wave beam.
