Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

The description about the satellite communication system mentioned in the embodiments of the present application is as follows:

in satellite communications, there are two modes of operation:

one is a transparent forwarding mode, the satellite only transparently forwards signals without any processing, and the terminal and the gateway station communicate, that is, the satellite only performs frequency conversion, wireless signal amplification and other operations on uplink/downlink signals, and the function of the satellite is similar to that of radio frequency relay.

One is a regenerative communication mode in which the satellite can detect information of a received signal, process and forward the information, perform a function of a base station, and connect a terminal and a gateway station. That is, the satellite may perform frequency translation, radio signal amplification, encoding/modulation, demodulation/decoding, etc. functions on the uplink/downlink signals. That is, the satellite may have all or part of the functionality of a base station (gNB) and may regenerate signals.

In satellite communications, the connection between the end user and the satellite is referred to as the user link, the connection between the satellite and the gateway station is the feeder link, and fig. 1 is a schematic diagram of a transparent forwarding mode.

For the transparent forwarding mode, the terminal and the gateway station experience transmission delay T1 of the feeder link and transmission delay T2 of the user link when performing data communication, and RTT (Round Trip Time) of transmission is 2 × (T1 + T2). In a beam cell, the maximum RTT corresponds to the transmission delay of the farthest terminal user and the network side (gateway station or satellite), and the minimum RTT corresponds to the transmission delay of the closest terminal user and the network side (gateway station or satellite). In a satellite system, based on a GEO (Geostationary Earth orbit satellite) system and a LEO (Low Earth orbit satellite) system in a transparent forwarding mode, maximum propagation delays are 541.46ms and 41.77ms, respectively. The propagation delay of a satellite system is large compared to a terrestrial system.

The uplink scheduling mechanism mentioned in the embodiments of the present application is introduced as follows:

referring to fig. 2, when Uplink data reaches a Buffer triggered BSR (Buffer Status Report) Report and a UE (User equipment) has no Uplink resource available for transmitting a BSR, if there is a PUCCH (Physical Uplink Control Channel) resource for transmitting a SR (Scheduling Request), the SR is transmitted in the PUCCH resource to Request an Uplink grant, and since the Scheduling Request is only an indication that the network UE needs Scheduling, the network does not know the size of all resources required for Scheduling the UE. The network may generally schedule the UE with a sufficiently large grant to transmit the BSR, so that the network may effectively schedule the UE, so the UE first transmits an SR to inform the network that scheduling is required, the network allocates an uplink grant to the UE to transmit the BSR, then the UE transmits the BSR to inform the network of the size of the data buffer, and the network schedules the UE according to the received uplink grant with a proper size scheduled by the BSR.

Selecting two-step random access resources and four-step random access resources:

for example, if the network side configures two-step random access resources and four-step random access resources, the two-step random access resources and four-step random access resources are selected through a configured Threshold msgA-RSRP-Threshold (i.e., a preset RSRP Threshold), if the measured downlink reference signal quality is higher than msgA-RSRP-Threshold, the two-step random access resources are selected as random access resources for sending BSR, and if the measured downlink reference signal quality is lower than msgA-RSRP-Threshold, the four-step random access resources are selected as random access resources for sending BSR.

It should be noted that the two-step random access resource described in the embodiment of the present application refers to a random access resource used in the two-step random access process; the four-step random access resource described in the embodiment of the present application refers to a random access resource used in a four-step random access process.

Referring to fig. 3, the two-step random access procedure is specifically as follows:

the two-step random access comprises competitive random access and non-competitive random access, and the process flow of the competitive random access process is as follows:

step 1: sending a message A (MSGA), transmitting a random access preamble and a Physical Uplink Shared CHannel (PUSCH) payload (payload);

step 2: message B (MSGB) is received and the contention is resolved.

If a successful random access response (success rar) is received, the two-step random access process is completed.

Referring to fig. 4, the four-step random access process is specifically as follows:

the four-step random access process is divided into competitive and non-competitive random access, and the flow of the random access process based on the competition is as follows:

step 1: sending message 1 (MSG 1), transmitting a random access preamble;

step 2: and receiving a message 2 (MSG 2), receiving a corresponding RAR accessed randomly, wherein the UL grant available for transmitting MSG3 is carried.

Step 3: sending message 3 (MSG 3), sending uplink scheduling transmission;

step 4: message 4 (MSG 4) is received and the contention resolution.

If the competition is resolved, the four-step random access process is completed.

In summary, when uplink data arrives and triggers a BSR, the UE needs to determine whether there is an available resource to send the BSR, and if both two-step random access resources and four-step random access resources are valid, how to select random access resources is a problem, and the existing selection based on the RSRP threshold only considers the channel condition, does not consider the service requirement for triggering the BSR, and is more prominent particularly in the NTN scenario.

According to the existing random access type selection mechanism, since the variation of RSRP (Reference Signal Receiving Power) in the NTN scenario is small, it may cause UEs in a satellite cell to select the same random access resource to send BSRs, resulting in a conflict of random access resources, and therefore, the scheme for selecting random access resources provided in the embodiment of the present application may adopt two-step random access resources to send BSRs for delay-sensitive service UEs and four-step random access resources to send BSRs for delay-insensitive service UEs.

Therefore, the embodiment of the present application provides a resource determination method and a resource determination indicating method and device, so as to provide a random access resource selection scheme when triggering a BSR, thereby better meeting the requirements of different services in different scenarios.

The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.

The method for selecting the random access resource to send the BSR, provided by the embodiment of the application, comprises the following steps:

the UE receives a condition configured in advance by a network side, selects random access resources according to the condition configured in advance by the network side, and/or selects the random access resources based on a mechanism for selecting an RA type based on an RSRP threshold;

and the UE transmits the BSR by using the selected random access resource.

Optionally, the preconfigured condition at the network side may be a preconfigured condition issued by the base station, and specifically may include at least one of the following conditions:

triggering a logical channel priority of a BSR;

triggering the QoS requirement of the logic channel of the BSR, wherein the QoS requirement can be selected as a mapping relation between the QoS requirement and the logic channel;

a distance from the UE to a reference point, wherein the reference point may be a satellite or a base station or a preset reference point;

time delay from the UE to a reference point, wherein the reference point can be a satellite or a base station or a preset reference point;

triggering a mapping restriction of the logical channel of the BSR.

Optionally, regarding how the UE selects the random access resource:

selecting according to the logic channel priority of the trigger BSR;

selecting according to the QoS requirement of the logic channel triggering the BSR;

when the BSR is triggered, selecting according to a distance from the UE to a reference point, where the reference point may be a satellite or a base station or a preset reference point (for example, may be a cell center, a cell edge, or the like);

when BSR is triggered, selecting according to the time delay from the UE to a reference point, wherein the reference point can be a satellite or a base station or a preset reference point;

the selection is made according to the mapping constraints of the logical channels triggering the BSR.

The method for combining the pre-configured conditions of the network side with the existing mechanism for selecting the Random Access (RA) type based on the RSRP threshold comprises at least one of the following steps:

the method comprises the following steps: judging whether the preset conditions of the network side are met or not; or, determining whether a preset condition based on the RSRP threshold is satisfied, for example, determining whether the measured downlink reference signal quality is higher than the RSRP threshold;

if one of the conditions is met, selecting two-step random access resources as the random access resources for sending the BSR; and otherwise, selecting four-step random access resources as the random access resources for sending the BSR.

Preferably, it is first determined whether a condition preconfigured on the network side is satisfied.

When the conditions pre-configured by the network side are met, selecting two-step random access resources as the random access resources for sending the BSR;

when the condition configured in advance by the network side is not met, judging whether the condition preset based on the RSRP threshold is met, specifically, for example, judging whether the measured downlink reference signal quality is higher than the RSRP threshold, if so, selecting two-step random access resources as random access resources for sending the BSR; and if the number is not higher than the preset value, selecting the four-step random access resource as the random access resource for sending the BSR.

The second method comprises the following steps: judging whether a condition configured in advance by a network side is met, judging whether a preset condition based on an RSRP threshold is met (specifically, judging whether the quality of a measured downlink reference signal is higher than the RSRP threshold), and if the two conditions are met, namely when the condition configured in advance by the network side is met and the quality of the measured downlink reference signal is higher than the RSRP threshold, selecting two-step random access resources as random access resources for sending the BSR; otherwise (i.e. neither of the two conditions is met, or only one of the two conditions is met), selecting the four-step random access resource as the random access resource for sending the BSR.

Optionally, when the pre-configured condition of the network side in the embodiment of the present application is two or more, then:

the method comprises the following steps: if the conditions pre-configured by any network side are met, random access resource selection can be carried out;

the second method comprises the following steps: the random access resource selection can be carried out only when the conditions (namely the preset necessary conditions) pre-configured by a specific network side are satisfied;

the third method comprises the following steps: the random access resource selection can be performed only if all network side preconfigured conditions are satisfied at the same time.

That is to say, the method provided in the embodiment of the present application, before determining the random access resource for sending the BSR based on the condition preconfigured on the network side, further includes:

when any one of conditions pre-configured by a network side is met, determining the selection of random access resources for transmitting the BSR; alternatively, the first and second electrodes may be,

when necessary conditions in conditions pre-configured by a network side are met, determining selection of random access resources for transmitting the BSR; alternatively, the first and second electrodes may be,

and when all conditions in the conditions pre-configured by the network side are met, determining the selection of the random access resources for transmitting the BSR.

Optionally, in the conditions preconfigured on the network side in the embodiment of the present application, each specific condition may be a threshold or a specific value (see the illustration of the subsequent embodiments specifically).

In addition, the mapping restriction on the logical channel triggering the BSR in the embodiment of the present application may include whether to disable the HARQ process and/or whether to allow the two-step random access procedure to be used.

Specific descriptions of several embodiments are given below:

the first embodiment is as follows: the selection is made according to the logical channel priority that triggers the BSR.

Step 1, the network side sends the conditions which are pre-configured by the network side and select random access resources according to the logic channel priority of the trigger BSR to the UE in a special signaling;

optionally, a BSR logical channel priority threshold is configured, and if the BSR logical channel priority threshold is lower than the BSR logical channel priority threshold, two steps of random access resources may be used to transmit the BSR;

step 2, when new data arrives and buffer (buffer) is empty or data with higher priority arrives, UE triggers BSR process;

and 3. The UE judges that the two-step random access resources and the four-step random access resources are available at the moment, judges that the priority of the logic channel triggering the BSR is lower than a threshold value according to the condition configured in advance by the network side in the step 1, and selects the two-step random access resources to send the BSR.

Example two: the selection is made according to the QoS requirements of the logical channels triggering the BSR.

Step 1, the network side sends the pre-configured conditions of the network side for selecting random access resources according to the logic channel QoS requirement of triggering BSR to UE in a special signaling;

optionally, if the QoS requirement of the configured BSR logical channel is a delay critical resource type (a professional term, i.e., a service with a high delay requirement), the BSR is sent using two-step random access resources, and if the QoS requirement is not the delay critical resource type, the BSR is sent using four-step random access resources;

step 2, when new data arrives and the buffer memory is empty or the data with higher priority arrives, the UE triggers the BSR process;

and 3, judging that the two-step random access resources and the four-step random access resources are available at the moment by the UE, judging that the QoS requirement of the logic channel triggering the BSR is a time delay key resource type according to the condition configured in advance by the network side in the step 1, and selecting the two-step random access resources to send the BSR.

Example three: the selection is made according to the distance of the UE from the reference point.

Step 1, the network side sends the pre-configured conditions of the network side for selecting random access resources according to the distance from the UE to a reference point to the UE in a special signaling;

optionally, a distance threshold from the UE to the reference point is configured, when the distance from the UE to the reference point is lower than the threshold, the BSR is sent by using two-step random access resources, and if the distance from the UE to the reference point is higher than the threshold, the BSR is sent by using four-step random access resources;

of course, the BSR may also be sent using two-step random access resources when the distance from the UE to the reference point is higher than the threshold, and sent using four-step random access resources if the distance from the UE to the reference point is lower than the threshold. The specific operation can be determined according to actual needs, and is not limited in the embodiments of the present application.

Step 2, when new data arrives and the buffer is empty or the data with higher priority arrives, the UE triggers the BSR process;

and 3. The UE judges that the two-step random access resources and the four-step random access resources are available at the moment, judges that the distance between the UE and the reference point is lower than a threshold value according to the condition configured in advance by the network side in the step 1, and selects the two-step random access resources to send the BSR.

Example four: the selection is made according to the time delay from the UE to the reference point.

Step 1, the network side sends the pre-configured conditions of the network side for selecting random access resources according to the time delay from the UE to a reference point to the UE in a special signaling;

optionally, a time delay threshold from the UE to the reference point is configured, when the time delay from the UE to the reference point is lower than the threshold, the BSR is sent by using two-step random access resources, and if the time delay from the UE to the reference point is higher than the threshold, the BSR is sent by using four-step random access resources;

of course, the BSR may also be sent by using two-step random access resources when the time delay from the UE to the reference point is higher than the threshold, and the BSR may be sent by using four-step random access resources if the time delay from the UE to the reference point is lower than the threshold.

Step 2, when new data arrives and the buffer is empty or the data with higher priority arrives, the UE triggers the BSR process;

and 3. The UE judges that the two-step random access resources and the four-step random access resources are available at the moment, judges that the time delay from the UE to the reference point is lower than a threshold value according to the conditions configured in advance by the network side in the step 1, and selects the two-step random access resources to send the BSR.

Example five: the selection is made according to the logical channel mapping restriction triggering the BSR.

Step 1, the network side sends the condition which is pre-configured by the network side for selecting random access resources to UE according to the logic channel mapping limitation of the trigger BSR in the special signaling;

optionally, configuring to select two-step random access resources when the logical channel mapping restriction triggering the BSR is that HARQ feedback is disabled, and select four-step random access resources when the logical channel mapping restriction triggering the BSR is that HARQ feedback is available;

step 2, when new data arrives and the buffer is empty or the data with higher priority arrives, the UE triggers the BSR process;

and 3, judging that the two-step random access resources and the four-step random access resources are available at the moment by the UE, judging that the logic channel mapping limitation of the triggered BSR is HARQ feedback forbidding according to the conditions configured in advance by the network side in the step 1, and selecting the two-step random access resources to send the BSR.

Example six: the method comprises the steps that a pre-configured condition of a network side is combined with a random access type selection mechanism based on a preset condition of an RSRP threshold.

The method comprises the following steps:

step 1, the network side sends any one or more conditions configured in advance by the network side to the UE in a special signaling;

step 2, when new data arrives and the buffer is empty or the data with higher priority arrives, the UE triggers the BSR process;

step 3.UE judges that two-step random access resources and four-step random access resources are available at this time, judge that two-step random access resources are available according to the conditions pre-configured in the network side in step 1, then choose two-step random access resources to send BSR, if judge that two-step random access resources are not available according to the conditions pre-configured in the network side in step 1, then execute step 4;

and 4, selecting by the UE according to the RSRP threshold value configured by the network side, if the measured RSRP is higher than the configured threshold value, selecting two-step random access resources, and otherwise, selecting four-step random access resources.

The second method comprises the following steps:
