Technical solution provided in an embodiment of the present invention is introduced below in conjunction with the accompanying drawings, during following introduction, incite somebody to action this For the technical solution that invention provides is applied in application scenarios shown in Fig. 2, and by taking the network equipment is base station as an example.

Fig. 3 is referred to, one embodiment of the invention provides a kind of random access configuration method, and the flow description of this method is such as Under.

S31, base station generate multiple downlink signals.

In embodiments of the present invention, signaling bearer is sent in specific resource, these specific resources can be above In " wave beam " mentioned.In order to distinguish different wave beams, hereinafter the wave beam for carrying the downlink signal that base station is sent is known as The downlink of base station sends wave beam or the transmission wave beam of base station.Correspondingly, the wave beam for the uplink signal that carrying base station receives can claim For the uplink receiving wave beam of base station or the reception wave beam of base station.

In one embodiment, downlink signal is synchronization blocks (Synchronization Signal block, SS Block), synchronization burst (SS burst), synchronization burst collection (SS burst set) and system information (System At least one of Information, SI).

Wherein, each downlink signal in multiple downlink signals is associated with corresponding random access configuration information, Mei Gesui Machine access configuration information is all used to indicate the random access resource for terminal equipment configuration, that is to say, that random access matches confidence Breath is for being terminal equipment configuration random access resource.In the embodiment of the present invention, random access configuration information includes being used to indicate Terminal device carries out the time configuration information of random access, and time configuration information includes the end that terminal device carries out random access At least one of time and duration and terminal device carry out the initial time of random access.

Because the quantity that different downlinks sends the terminal device in wave beam may be different, such as some downlinks hair Send the quantity of terminal device in wave beam big, and the quantity that some downlinks send terminal device in wave beam is small.It can be found in Fig. 4, downlink Sending has the terminal device of 2 times of quantity in wave beam 1, and downlink sends the terminal device for there was only 1 times of quantity in wave beam 2.For end Downlink more than the quantity of end equipment sends wave beam, while the quantity for initiating the terminal device of random access also can be more, conversely, eventually The downlink of the negligible amounts of end equipment sends wave beam, while the quantity for initiating the terminal device of random access is also less.For this Kind situation sends wave beam if it is all downlinks and is all associated with identical random access configuration information, then or terminal device Downlink more than quantity sends the downlink that the associated random access resource of wave beam is insufficient or terminal device quantity is few and sends wave beam pass The random access resource of connection again can be remaining, results in waste of resources.

Therefore in embodiments of the present invention, the random access configuration information associated by multiple downlink signals is different, this In difference, it can be understood as have in the random access configuration information associated by multiple downlink signals part random access match confidence Remaining random access configuration information is different together for manner of breathing, or it can be appreciated that connecing at random associated by multiple downlink signals Enter configuration information to be all different.If two random access configuration informations are different, the two random access configuration information institutes The random access resource of instruction is just different.

Fig. 5 A are referred to, are mainly compiled including frame with the relevant information of random access in down-going synchronous information and system information Number, the beam scanning period, current beam index and random access configuration information.Random access configuration information includes connecing at random Enter time configuration information where resource, leading format, frequency location and sequence, power information etc..

Wherein time configuration information is used to indicate terminal device and carries out multi-upstream access, multi-upstream access here, including random Access, scheduling request, beam optimization (beam refinement) or system information request, herein when introducing mainly with For machine access.In time configuration information, include the density of random access in time, for example, there is K son in per N number of frame Frame is used at least one of random access and the corresponding reception signal scan cycle of random access, and including connecing at random Enter the initial time of resource and the initial time and duration of end time or random access resource.Initial time or end Time includes frame, subframe, time slot, small time slot (mini-slot) and orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol at least one of number.One frame, subframe, small time slot or time slot, It is to be made of multiple OFDM symbols.Such as the number of frame, time slot, small time slot and OFDM symbol is needed, then time configuration information Can include the number of frame, time slot, small time slot and OFDM symbol, that is to say, that the content included by time configuration information can Determines according to actual conditions.Duration can be used in sub-frame number, number of timeslots, small time slot quantity, OFDM symbol quantity At least one indicates.Refer to Fig. 5 B, for the associated random access resources of downlink signal k and with downlink signal j it is associated with The time configuration information of the schematic diagram of machine access-in resource, the two random access resources is obviously different.In figure 5B, it sends Wave beam k is that the downlink of bearing downlink signal k sends wave beam, sends the downlink that wave beam j is bearing downlink signal j and sends wave beam.

Next the frame format for introducing random access, refers to Fig. 5 C.One running time-frequency resource region for being used for random access It is made of N number of subframe, time slot, small time slot or OFDM symbol.At the same time on position, there can be polylith frequency domain resource Region, each random access running time-frequency resource region can be adjacent on frequency domain, also non-conterminous, i.e., different random access time-frequencies money There are vacant frequency domain or the frequency domain of other transmitting uplink datas among source region.Shared by each random access running time-frequency resource region Frequency domain width and/or time width can be identical, can not also be identical.

For example, random access running time-frequency resource is made of N number of time slot, the embodiment of the present invention provides three kinds of formats, refers to figure 5D.Wherein format 1, each time slot are made of K random access guiding and one section of guard time.Particularly, for specific Time slot, tail portion is guard time in the time slot, and the end time of guard time and the alignment of the end time of time slot.Correspondingly, The head of next time slot and the alignment of the head of specific random access guiding.In format 2, in the same area each time slot with Machine access lead is adjacent in time, and the rearmost position of only the last one time slot in region is provided with guard time.Protection Other upstream datas or downlink transmission data of the time for being located next to random access resource region on guard time.Especially , for format 2, for the last one time slot that the random access resource is included, the tail portion of the time slot is guard time, and The end time of guard time and the end time alignment of time slot.And for other time slots, it is not present guard time, and time slot End time can get along well the end time alignment of random access guiding, and correspondingly, the heads of these time slots can get along well specific Random access guiding head alignment.In format 3, optionally, the start bit of each time slot be equipped with other upstream datas or Person's downlink data, such as down control channel data or uplink control channel data.In format 3, optionally, each time slot There are other upstream datas either downlink data such as uplink control channel data or down control channel number in the position of ending According to before other data of the position of each time slot ending, being provided with guard time.Format 3 can with format 1 or format 2 with Any way combines.In other embodiment, above random access running time-frequency resource region by N number of subframe, small time slot or OFDM symbol is constituted.The above K and N can select for a post meaning positive integer, terminal device can be tabled look-up according to random access configuration information or It is calculated according to formula.

So, because the embodiment of the present invention supports the random access configuration information associated by multiple downlink signals different, net Network equipment also can be to be associated with different random access configuration informations for different downlink signals.In one embodiment, net Network equipment can be right according to being associated with different random access configuration informations the case where the quantity of terminal device for different downlink signals In covering terminal device more than downlink signal, can be connect for the random of a fairly large number of random access resource of its association instruction Enter configuration information, and for the few downlink signal of the terminal device of covering, can be the random of the negligible amounts of its association instruction The random access configuration information of access-in resource.In other embodiment, the network equipment can be difference according to application scenarios Downlink signal be associated with different random access configuration informations, such as the small downlink signal of coverage area, can be closed for it The shorter random access resource of connection instruction time span, and for the big downlink signal of coverage area, can be its association instruction The longer random access resource of time span.
