Methods, devices, terminals, and network-side equipment for determining random access resources
[0001] This disclosure claims priority to Chinese Patent Application No. 202510382237.9, filed with the Chinese Patent Office on March 28, 2025, entitled “Method, Apparatus, Terminal and Network-Side Equipment for Determining Random Access Resources”, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, terminal and network-side equipment for determining random access resources. Background Technology
[0003] Network energy conservation research mainly discusses various technologies that help reduce the energy consumption of network devices from the perspectives of time domain, frequency domain, spatial domain, and power domain. For terminals, it is necessary to first determine random access resources and then initiate a random access procedure based on those resources.
[0004] The current random access resources are configured by the base station. The base station checks the random access preamble on all configured random access channel occasions (ROs) to determine whether the user equipment (UE) has initiated a random access procedure. However, the random access procedure is initiated by the UE. If the UE does not send the random access preamble on the RO, the base station still needs to check the random access preamble on the corresponding RO, resulting in wasted energy for the base station.

[0056] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.
[0057] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.
[0058] The embodiments of this disclosure provide a method, device terminal, and network-side equipment for determining random access resources, in order to solve the problem of energy waste in the random access process.
[0059] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.
[0060] As shown in Figure 1, an embodiment of this disclosure provides a method for determining random access resources, applied to a terminal, specifically including the following steps:
[0061] Step 101: Determine the first random access resource based on the first information, wherein the first random access resource is used to send the preamble;
[0062] The first information includes at least one of the following:
[0063] The terminal sends a first uplink signal, which is used to wake up or request the first random access resource;
[0064] The network-side device sends an indication message, and the first random access resource determined based on the indication message is a random access resource within a first time range.
[0065] In this embodiment, the terminal can determine a first random access resource based on a first uplink signal and / or indication information sent by the network-side device. This first random access resource is the resource the terminal uses to send a preamble. The network-side device can receive the preamble on this first random access resource. This preamble can be a random access preamble, also referred to as the first uplink signal in the random access process, such as Message1 (Msg 1) in a four-step random access process or Message A (Msg A) in a two-step random access process. The first random access resource can be at least a portion of the random access resources configured by the network-side device, and can be considered a usable random access resource. In some embodiments, after determining the first random access resource, the terminal can use it to send a preamble. The network-side device and the terminal have the same understanding of the first random access resource, and the network-side device can receive the preamble sent by the terminal on this first random access resource.
[0066] The first uplink signal can be sent by the terminal that determines the first random access resource. For example, terminal A sends the first uplink signal and determines the first random access resource based on the first uplink signal. Terminal A can use the first uplink signal to wake up or request the first random access resource to send a preamble. Alternatively, the first uplink signal can also be sent by another terminal, which is a terminal other than the terminal that determines the first random access resource. For example, terminal B sends the first uplink signal, which is used to wake up or request the first random access resource. Terminal A determines the first random access resource based on the first uplink signal sent by terminal B. For example, if terminal A receives feedback information from the network-side device regarding the first uplink signal sent by terminal B, and the feedback information includes confirmation information, terminal A can use the first uplink signal to wake up or request the first random access resource to send a preamble.
[0067] In some embodiments, the first uplink signal may be an uplink wake-up signal (UL WUS) or other uplink signals, such as uplink signals that can trigger a System Information Block (SIB) or SIB1. The terminal sends the first uplink signal to the network-side device. The first random access resource requested or woken up by this first uplink signal may be at least a portion of the random access resources configured by the network-side device. For example, the terminal receives random access resource configuration information sent by the network-side device, and the terminal sends the first uplink signal to the network-side device to request the first random access resource, which is a portion of the random access resources configured in the configuration information. The terminal and the network-side device determine the first random access resource based on the first uplink signal with the same understanding. The terminal can then send a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource, avoiding the need for the network-side device to detect preambles on all configured random access resources, thus saving energy.
[0068] The terminal and network-side equipment can also determine the first random access resource based on the indication information sent by the network-side equipment. This can be understood as the network-side equipment indicating available random access resources through the indication information. The indication method can be direct, such as the indication information directly indicating available random access resources, or indirect, such as indicating unavailable random access resources, from which the terminal further determines available random access resources. The first random access resource determined based on this indication information can be at least a portion of the random access resources configured by the network-side equipment. If the first random access resource determined based on this indication information is a random access resource within a first time range, the terminal can send a preamble on the random access resources within that first time range. Correspondingly, the network-side equipment detects the preamble on the random access resources within that first time range. This avoids the need for the network-side equipment to detect preambles on all configured random access resources, saving energy.
[0069] In some embodiments, the terminal may also determine the first random access resource based on both the first uplink signal and the indication information sent by the network-side device. For example, the terminal sends the first uplink signal to wake up or request the first random access resource; the network-side device sends indication information to the terminal based on the first uplink signal, and the terminal further determines the first random access resource based on the indication information.
[0070] In some embodiments, the random access resource in this disclosure may be a RO. The available random access resource in this disclosure may also be understood as a valid (or effective) random access resource; the unavailable random access resource may also be understood as an invalid (or failed) random access resource.
[0071] In embodiments of this disclosure, the terminal determines a first random access resource based on a first uplink signal and / or indication information sent by a network-side device. The terminal can send a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource, thereby ensuring accurate reception of the preamble sent by the terminal. This method can more flexibly determine available random access resources and avoid the power consumption waste caused by the network-side device frequently detecting random access resources.
[0072] As an optional embodiment, determining the first random access resource based on the first information includes:
[0073] The random access resource associated with the first uplink signal is determined to be the first random access resource;
[0074] or,
[0075] Upon receiving feedback information from the network-side device regarding the first uplink signal, wherein the feedback information includes confirmation information, it is determined that the random access resource associated with the first uplink signal is the first random access resource.
[0076] In this embodiment, if the terminal transmits a first uplink signal during a first uplink signal transmission opportunity, the random access resource associated with the first uplink signal is considered to be a first random access resource, or it can be understood as considering the random access resource associated with the first uplink signal to be an available random access resource. The terminal can transmit a preamble on the first random access resource. When the network-side device receives the first uplink signal, it considers the first random access resource associated with the first uplink signal to be available, and the network-side device receives the preamble on the first random access resource.
[0077] Alternatively, after transmitting the first uplink signal on the first uplink signal transmission opportunity, the terminal determines, based on the feedback information of the first uplink signal (if the feedback information includes acknowledgment information), that the random access resource associated with the first uplink signal is a first random access resource. This can also be understood as determining, based on the feedback information, that the random access resource associated with the first uplink signal is an available random access resource, and the terminal can transmit a preamble on that first random access resource. If the terminal does not receive feedback information for the first uplink signal, or receives feedback information for the first uplink signal but the feedback information does not include acknowledgment information, then the random access resource associated with the first uplink signal is considered unavailable.
[0078] If the network-side device receives the first uplink signal and sends feedback information (including confirmation information) to the terminal, it considers the first random access resource associated with the first uplink signal to be available, and the network-side device receives the preamble on the first random access resource.
[0079] As an optional embodiment, the method further includes:
[0080] Before sending the first uplink signal, it is determined that the random access resource associated with the first uplink signal is an unavailable random access resource;
[0081] or,
[0082] Before receiving feedback information from the network-side device regarding the first uplink signal, and before the feedback information includes acknowledgment information, it is determined that the random access resource associated with the first uplink signal is an unavailable random access resource.
[0083] In this embodiment, before sending the first uplink signal, the terminal assumes that the random access resource associated with the first uplink signal is unavailable; only after sending the first uplink signal is the terminal considered that the random access resource associated with the first uplink signal is available. Alternatively, before sending the first uplink signal but receiving feedback information (including acknowledgment information) from the network-side device, the terminal considers the random access resource associated with the first uplink signal unavailable; only when the received feedback information includes acknowledgment information is the terminal considered that the random access resource associated with the first uplink signal is available.
[0084] Before receiving the first uplink signal sent by the terminal, the network-side device considers the random access resource associated with the first uplink signal to be unavailable, which can also be understood as not detecting the random access resource associated with the first uplink signal by default; or, if the network-side device receives the first uplink signal sent by the terminal but does not send an acknowledgment message to the terminal, it considers the random access resource associated with the first uplink signal to be unavailable and does not detect the random access resource associated with the first uplink signal.
[0085] As an optional embodiment, the random access resource associated with the first uplink signal is a random access resource within a first time range.
[0086] In this embodiment, the first uplink signal is associated with random access resources, and the random access resources associated with the first uplink signal are random access resources within a first time range. These random access resources within the first time range can be at least a portion of the random access resources configured by the network-side device. The terminal can then send a preamble on these random access resources within the first time range, and correspondingly, the network-side device detects the preamble on these random access resources within the first time range.
[0087] As an optional embodiment, the first uplink signal is associated with random access resources within a first time range, and the association includes at least one of the following:
[0088] (1) The generation sequence of the first uplink signal is related to the random access resources within the first time range; for example, different sequences can correspond to different random access resources within the first time range.
[0089] (2) The resource location of the first uplink signal is associated with the random access resources within the first time range; for example, the resource location of the first uplink signal and the location of the random access resources within the first time range satisfy a preset offset or satisfy the offset configured by the network side device; for another example, different resource locations of the first uplink signal can correspond to different random access resources within the first time range.
[0090] (3) The indication field carried by the first uplink signal is associated with the random access resources within the first time range. For example, the random access resources within the first time range can be indicated within the indication field carried by the first uplink signal, and different indication fields carried by the first uplink signal can indicate different random access resources within the first time range.
[0091] In this embodiment, the first uplink signal is associated with random access resources within a first time range. The terminal and the network-side device have a consistent understanding of this association. After the terminal sends the first uplink signal, the network-side device can determine the random access resources associated with the first uplink signal based on this association, thereby determining that the random access resources associated with the first uplink signal are available.
[0092] As an optional embodiment, the indication information includes at least one of the following:
[0093] (1) First indication information, used to indicate that random access resources are available and / or unavailable within the first time range;
[0094] In this scenario, the network-side device indicates the availability and / or unavailability of random access resources within a first time range via the first indication information. For example, the terminal receives configuration information of random access resources and the first indication information sent by the network-side device. Based on the configuration information of the random access resources, candidate random access resources can be determined, and based on the first indication information, the availability and / or unavailability of random access resources within a first time range among the candidate random access resources can be determined.
[0095] For example, if the first indication information indicates that random access resources within a first time range are available, the terminal can determine that the random access resource within the first time range is the first random access resource based on the first indication information, and thus can send a preamble.
[0096] For example, before receiving the first indication information, the terminal assumes that random access resources within a first time range are available. Upon receiving the first indication information, which indicates that random access resources within the first time range are unavailable, the terminal determines that the random access resources within that first time range are unavailable. Alternatively, if the first indication information indicates that random access resources within the first time range are unavailable, the terminal can further determine available random access resources based on the unavailable random access resources. For example, it can determine that among all candidate random access resources configured by the network-side device, resources other than the unavailable random access resources are available.
[0097] (2) Second indication information, used to indicate the configuration information of the first random access resource.
[0098] In this embodiment, the network-side device can directly indicate the configuration information of the first random access resource through the second indication information. The configuration information may be, for example, the time-domain configuration information and / or frequency-domain configuration information of the first random access resource. In this way, the terminal can directly determine the first random access resource and can send a preamble in the first random access resource.
[0099] In some embodiments, the method further includes: determining, before receiving the first indication information, that the random access resources within the first time range are unavailable random access resources.
[0100] In this embodiment, before receiving the first indication information, the terminal assumes that random access resources within a first time range are unavailable. For example, it assumes that the ROs within the first time range are invalid ROs. Only when the network-side device sends the first indication information, and the first indication information indicates that the ROs within the first time range are available (or valid), are the ROs within the first time range considered valid ROs. At this time, the terminal can send a preamble on the ROs within the first time range. The network-side device only receives the preamble on the ROs within the first time range when it sends the first indication information and the first indication information indicates that the ROs within the first time range are available (or valid), thereby saving energy consumption.
[0101] In some embodiments, before receiving the first indication information, the terminal determines that the random access resources within the first time range are available random access resources. In this embodiment, before receiving the first indication information, the terminal assumes that the random access resources within the first time range are available, for example, it assumes that the ROs within the first time range are valid ROs. Only when the network-side device sends the first indication information, and the first indication information indicates that the ROs within the first time range are unavailable (or invalid), are the ROs within the first time range considered invalid ROs. At this time, the terminal will not send a preamble on the ROs within the first time range, and the network-side device will not detect the preamble on the ROs within the first time range, thus avoiding wasted energy.
[0102] In some embodiments, the indication information includes information for determining the first time range. For example, when indicating the availability and / or unavailability of random access resources within a first time range via first indication information, the first indication information may also include information for determining the first time range. As another example, when indicating the configuration information of a first random access resource via second indication information, information about the first time range corresponding to that first random access resource may also be indicated. The information for determining the first time range may include one or more of the following: the random access resources included in the first time range, the number of PRACH association periods corresponding to the first time range, the length of the first time range, the period of the first time range, etc.
[0103] In some embodiments, the indication information is group common downlink control information (DCI). The network-side device can use this DCI to indicate the availability and / or unavailability of random access resources within a first time range; and / or use this DCI to indicate the configuration information of the first random access resource.
[0104] As an optional embodiment, the random access resources within the first time range include random access resources corresponding to M random access resource units, where M is a positive integer.
[0105] In this embodiment, the random access resources within the first time range can be divided into one or more random access resource units (ROs), and each RO may include one or more ROs. In some embodiments, the candidate random access resources configured by the network-side device can also be divided into one or more candidate random access resource units, and the M random access resource units included in the first time range are at least a portion of the candidate random access resource units configured by the network-side device. Thus, the granularity of the first random access resource that the terminal wakes up or requests through the first uplink signal, the random access resource indicated by the network-side device through indication information, and the first random access resource determined by the terminal according to the indication information can all be ROs.
[0106] As an optional embodiment, the random access resource corresponding to the random access resource unit is determined according to the second information, which includes at least one of the following:
[0107] 1) The number of Physical Random Access Channel (PRACH) association periods corresponding to one random access resource element;
[0108] In this embodiment, the random access resources (such as ROs) contained in a random access resource unit can be determined according to the PRACH association period. For example, a random access unit corresponds to X (X is greater than 0) PRACH association periods. The PRACH association period is the period during which the synchronization signal blocks (SSBs) in different beam directions and all ROs complete one round of mapping. Based on the number of PRACH association periods corresponding to a random access unit, the number of random access resources (such as ROs) contained in a random access unit can be determined.
[0109] 2) Number of beams in a Synchronization Signal Block (SSB); The number of random access resources contained in a random access resource unit (RO) can also be determined based on the number of beams in the SSBs contained in the RO. For example, if an RO corresponds to x SSBs, then the number of ROs contained in a random access resource unit can be determined.
[0110] 3) The number of SSB beams corresponding to one random access opportunity (RO); the number of random access resources (such as RO) contained in a random access resource element can also be determined based on the number of SSB beams corresponding to one RO. For example, one RO corresponds to x SSBs, and the number of ROs contained in a random access resource element can be determined based on the number of SSBs.
[0111] 4) Configuration information related to Random Access Resource Units (ROs) sent by the network-side device, including the length and / or period of the RO. The network-side device can configure the random access resources corresponding to a RO using this configuration information. For example, configuring the length of a RO determines the number of ROs corresponding to that length; similarly, configuring the period of a RO allows the determination of the number of ROs contained within that period. This configuration information can be configuration information used to configure random access resources or independent configuration information.
[0112] As an optional embodiment, the first indication information indicates the availability and / or unavailability of random access resources within the first time range, including one of the following:
[0113] (a) The first indication information includes a first field, which includes 1 bit of information, and the 1 bit of information is used to indicate whether the random access resources corresponding to the M random access resource units are available or unavailable;
[0114] The first indication information may be group common downlink control information (DCI). The first field of the DCI may be 1 bit, which indicates whether the random access resources corresponding to the M random access resource elements are available (or active) or unavailable (or inactive). That is, different random access resource elements among the M random access resource elements are not indicated independently.
[0115] (b) The first indication information includes a first field, which includes M bits of information, each bit of the M bits of information being used to indicate whether the random access resource corresponding to one of the M random access resource units is available or unavailable;
[0116] The first indication information may be a Group Common Downlink Control Information (DCI). The first field of the DCI may be of length M bits, such as a bitmap of length M. The M bits in the bitmap indicate whether the random access resource corresponding to each of the M random access resource units is available (or active) or unavailable (or inactive). That is, different random access resource units among the M random access resource units can be indicated independently.
[0117] (c) The first indication information includes a first field, which includes Y bit information. Each bit in the Y bit information is used to indicate whether the random access resource corresponding to a random access resource unit group among M random access resource units is available or unavailable. Y is a positive integer, and a random access resource unit group includes at least one random access resource unit.
[0118] The first indication information may be Group Common Downlink Control Information (DCI). The first field of this DCI may be Y bits or a bitmap of length Y, where each bit corresponds to a group of Random Access Resource Units (RLUs), and each bit indicates whether the random access resources in a RLU group are available (or active) or unavailable (or ineffective). Alternatively, the Y bits in the bitmap may respectively indicate the availability (or active) or unavailable (or ineffective) of each of the Y RLU groups. Each RLU group contains one or more RLUs, and each RLU contains one or more random access resources.
[0119] In embodiments of this disclosure, the random access resources corresponding to the first time range are determined based on third information, which includes at least one of the following:
[0120] 1) The number of PRACH association cycles corresponding to the first time range; In this embodiment, the first time range may correspond to y PRACH association cycles, which is the cycle in which SSB and all RO complete one round of mapping. When the length of the PRACH association cycle is known, the length of the first time range can be determined.
[0121] 2) Number of SSB beams; The first time range can be determined based on the number of SSB beams contained in the first time range. For example, the number of ROs contained in the first time range can be determined based on the mapping relationship between SSB and RO.
[0122] 3) The number of SSB beams corresponding to one RO; for example, the number of ROs in the first time range can be determined based on the number of SSB beams contained in the first time range and the number of SSB beams corresponding to one RO.
[0123] 4) Configuration information for a first time range sent by the network-side device, wherein the configuration information includes: the length and / or period of the first time range. For example, if the network-side device configures the length of the first time range, the number of ROs corresponding to that length can be determined; or, for example, if the network-side device configures the period of the first time range (e.g., 160ms), the number of ROs included in the first time range can be determined based on the number of ROs within that period. The configuration information can be configuration information for configuring random access resources or independent configuration information.
[0124] As an optional embodiment, the method further includes:
[0125] If the indication information is received at the first location but not at the second location, the first random access resource determined based on the indication information received at the first location remains available.
[0126] The second position is the location where the indication information is sent after the first position.
[0127] In this embodiment, when the terminal receives indication information (which may be either first or second indication information) at a first location, and does not receive new indication information at a subsequent second location, the indication information previously received at the first location can be considered to remain valid, meaning the first random access resource determined based on the indication information received at the first location remains available. If the terminal receives new indication information at the second location, the first random access resource is re-determined based on the new indication information.
[0128] As an optional embodiment, the types of random access resources include: general random access resources and on-demand random access resources;
[0129] Wherein, if the network-side device is configured with the general random access resource, the terminal determines that the general random access resource is an available random access resource;
[0130] When the network-side device is configured with the on-demand random access resources, the terminal determines the first random access resource from the on-demand random access resources based on the first information.
[0131] In this embodiment, the type of random access resource may include: normal random access resource and on-demand random access resource. The terminal and network-side device consider normal random access resource to be effective (or available) immediately after configuration. For on-demand random access resource, the terminal and network-side device use the method described above for determining the first random access resource based on the first information to determine its availability (or effectiveness). This can also be understood as the method for determining the first random access resource based on the first information in this embodiment being for on-demand random access resource.
[0132] The following example illustrates a method for determining random access resources in an embodiment of this disclosure.
[0133] Example 1: The terminal determines the first random access resource based on the first uplink signal. Taking the network-side device as a base station (such as a gNB) and the first uplink signal as the first UL WUS as an example, it should be noted that the network-side device can also be other access network devices, which are not limited here.
[0134] The gNB sends configuration information for random access resources in system messages. This configuration information is used to configure candidate random access resources. This configuration information may include time-domain and frequency-domain configuration information, such as the PRACH configuration index. Based on this configuration information, the UE can determine candidate random access resources. These candidate random access resources are not immediately available (or effective or valid); that is, the UE cannot directly send a random access preamble on the random access opportunities included in the candidate random access resources. The candidate random access resources configured in the system messages can also be referred to as on-demand random access resources.
[0135] The configuration information of the random access resources can divide the random access resources into M random access resource elements, with the first UL WUS corresponding to the M random access resource elements. When a UE has UL data and wishes to initiate random access, the UE can send a first UL WUS at the first UL WUS opportunity to wake up or request the M random access resource elements corresponding to (or associated with) the first UL WUS. The M random access resource elements corresponding to (or associated with) the first UL WUS can also be referred to as the first random access resources. The UE wakes up or requests the first random access resources by sending the first UL WUS.
[0136] In some embodiments, M=1, which can also be understood as one first UL WUS corresponding to one random access resource unit, and different UL WUS corresponding to different random access resource units. The correspondence or association between the first UL WUS and the random access resource may include at least one of the following:
[0137] The generation sequence of the first UL WUS is associated with a random access resource unit (RLU), and different sequences correspond to different RLUs.
[0138] The transmission location of the first UL WUS is associated with the random access resource unit, for example, the two meet a preset offset or meet the offset configured by the network-side device;
[0139] The first UL WUS indication field indicates the associated random access resource unit.
[0140] Based on whether the gNB responds with feedback information corresponding to the first UL WUS after the UE sends the first UL WUS wake-up or requests the first random access resource, it can be divided into the following two branches:
[0141] Branch 1: After the UE sends the first UL WUS on the first UL WUS opportunity, the UE considers the M random access resource elements corresponding to the first UL WUS to be effective (or available) random access resources, and then determines that the M random access resource elements are the first random access resources.
[0142] As shown in Figure 2, assuming that a first UL WUS corresponds to a RO unit, when the UE sends the first UL WUS on the first UL WUS opportunity, the RO unit corresponding to the first UL WUS is a valid (or available) RO unit (for example, RO unit 1, RO unit N); at this time, after the gNB detects the first UL WUS sent by the UE, the gNB will detect the random access preamble on the RO included in the RO unit corresponding to the first UL WUS.
[0143] When the UE does not send the first UL WUS at the first UL WUS opportunity, the RO unit corresponding to the first UL WUS is an invalid (or unavailable) RO unit (e.g., RO unit N-1). At this time, when the gNB does not detect the first UL WUS, the gNB does not detect the random access preamble on the RO included in the RO unit corresponding to the first UL WUS, thereby reducing the power consumption of the gNB.
[0144] At this time, the gNB behavior is as follows: by default, the gNB does not detect the ROs included in the M random access resource elements corresponding to the first UL WUS. Only after the gNB detects the first UL WUS sent by the UE will the gNB detect the ROs of the M random access resource elements corresponding to the first UL WUS.
[0145] Branch 2: After detecting the first UL WUS, the gNB will send feedback information of the first UL WUS to the terminal. After the UE sends the first UL WUS on the first UL WUS opportunity, the UE determines the M random access resource elements corresponding to the first UL WUS as effective (or available) random access resources, i.e., the first random access resources, based on the feedback information of the first UL WUS (the feedback information includes confirmation information).
[0146] At this time, the gNB behavior is as follows: by default, the gNB does not detect the ROs included in the M random access resource elements corresponding to the first UL WUS. Only when the gNB detects the first UL WUS sent by the UE and sends feedback information to the terminal, and the feedback information includes confirmation information, will the gNB detect the ROs of the M random access resource elements corresponding to the first UL WUS.
[0147] It should be noted that the concept of a random access resource element (RUIRF) is used in this example description. Other descriptions are also possible, such as random access resource, random access resource element group, etc., without limitation (applicable to other embodiments). The RUIRF here allows the gNB and UE to align their understanding of the "random access resource corresponding to the first UL WUS." If the UE sends the first UL WUS at the first UL WUS opportunity, the UE and gNB, based on their consistent understanding of the "random access resource corresponding to the first UL WUS," can unanimously determine which random access resources are available (or valid) without ambiguity.
[0148] The random access opportunities corresponding to a random access resource unit (RLU) can be defined by protocol, such as: all ROs that complete one round of mapping between SSBs and ROs constitute the ROs included in a random access resource unit (RLU), that is, one RLU corresponds to one PRACH association period. In this case, the number of ROs included in the RLU is related to the number of SSBs and the number of SSBs corresponding to one RO.
[0149] The ROs included in a Random Access Resource Unit (RLU) can also be determined based on configuration information sent by the gNB. This configuration information includes the length of the RLU, for example, a RLU length of 32ms. The configuration information may also include the period of the RLU; the ROs included within one period constitute the RLU.
[0150] In this embodiment, the terminal determines the first random access resource based on the first uplink signal, and can then send a preamble on the first random access resource. The network-side device receives the preamble on the first random access resource based on the same understanding, which can reduce energy consumption.
[0151] Example 2: The terminal determines the first random access resource based on the first indication information sent by the network-side device. Taking the network-side device as a base station (such as a gNB) as an example, it should be noted that the network-side device can also be other access network devices, which are not limited here.
[0152] The gNB sends configuration information for random access resources in system messages. This configuration information may include time-domain and frequency-domain configuration information of candidate random access resources. The candidate random access resources determined by the UE are not immediately available (or effective or valid) random access resources.
[0153] The configuration information for random access resources can divide the random access resources into M random access resource units. The gNB can send a first indication message, which indicates whether the M random access resource units are available (or active) or unavailable (inactive). The candidate random access resources configured in the system message can also be called on-demand random access resources. The gNB can dynamically indicate the available (or active) random access resources through the first indication message.
[0154] The first indication information can be group common DCI. The gNB can configure relevant configuration information for group common DCI detection, such as search space configuration information and CORSET configuration information. Additionally, the gNB can send configuration information to determine the correspondence between the first indication information and the M random access resource elements (RLUs). The UE can determine the M RLUs corresponding to the first indication information based on this configuration information. Therefore, after receiving the first indication information, the UE can determine the available (or effective) M RLUs. Here, the correspondence between the first indication information and the M RLUs can also be predefined by the protocol; this embodiment does not limit this.
[0155] The Group Common DCI can be located before the M Random Access Resource Elements (RLUs). The fields included in the Group Common DCI can indicate the availability (or effectiveness) or inaccessibility (or failure) of the M RLUs. The UE can only send the random access preamble using the corresponding ROs of those M RLUs after determining their availability based on the Group Common DCI. How the Group Common DCI indicates the availability (or effectiveness) or inaccessibility (or failure) of the M RLUs can include the following branches:
[0156] Branch 1: The Group common DCI can include a 1-bit field that indicates the availability (or effectiveness) or inaccessibility (or failure) of M random access resource units (RRPs), meaning that different RRPs among the M RRPs are not independently indicated; specifically, M can be equal to 1, meaning that there is an opportunity to send the Group common DCI before each RRP.
[0157] Branch 2: The Group common DCI includes fields that can be a bitmap of length M, where the M bits in the bitmap indicate whether each of the M random access resource units is available (or active) or unavailable (or inactive), meaning that different random access resource units can be indicated independently.
[0158] Branch 3: The Group common DCI can include Y bits as the field, with each bit corresponding to a random access resource unit (RLU) group, and each RLU group including at least one RLU. For example, the M RLUs corresponding to the first indication information can be divided into at least one RLU group. For instance, M can be equal to 8, and a RLU group includes 4 RLUs. In this case, the Group common DCI can include Y = 2 bits as the field, which indicates two different RLU groups respectively.
[0159] Branch 4: The fields included in the Group common DCI can be bitmaps of length Y, where the Y bits in the bitmap indicate the availability (or effectiveness) or inaccessibility (or failure) of each of the Y random access resource unit (RLU) groups. For example, the M RLUs corresponding to the first indication information can be divided into at least one RLU group. For instance, M can be equal to 8, and a RLU group includes 4 RLUs. In this case, the fields included in the Group common DCI can be 2 bits long, indicating two different RLU groups.
[0160] As shown in Figure 3, a first indication information (DCI) corresponds to M random access resource units (RO units). The DCI includes M bits or a bitmap of length M. Different bits correspond to different RO units, indicating whether different RO units are available (or active) or unavailable (or ineffective). For example, RO unit 1 and RO unit M are active RO units, and RO unit M-1 is an unavailable (or ineffective) RO unit. After the gNB sends the first indication information, the gNB and UE can align their understanding of the available (or active) random access resources through the indication of the first indication information. Correspondingly, the UE can send a random access preamble on the available (or active) random access resources, and the gNB needs to detect the random access preamble on the available (or active) random access resources.
[0161] UE behavior at this time: The UE defaults to the M random access resource elements including the ROs as unavailable or invalid ROs. Only after the gNB sends the first indication information and the first indication information indicates that the M random access resource elements are available (or effective) will the UE consider the M random access resource elements including the ROs as available or effective ROs.
[0162] Alternatively, the UE defaults to the M random access resource elements (RUIs) including the ROs as available or valid RUIs. Only after the gNB sends the first indication information and the first indication information indicates that the M RUIs are unavailable or invalid will the UE consider the M RUIs including the ROs as unavailable or invalid RUIs.
[0163] In this embodiment, the terminal determines the first random access resource based on the first indication information sent by the network-side device, and can then send a preamble on the first random access resource. The network-side device receives the preamble on the first random access resource based on the same understanding, which can reduce energy consumption.
[0164] Example 3: The terminal determines the first random access resource based on the second indication information sent by the network-side device. Taking the network-side device as a base station (such as a gNB) as an example, it should be noted that the network-side device can also be other access network devices, which are not limited here.
[0165] The gNB sends a second indication message, which may include configuration information of available (or effective) random access resources. For example, it may include only the temporal resource configuration information of the random access resources or all the configuration information of the random access resources. The system message sent by the gNB needs to include the configuration information of the second indication message, such as the detection period and detection window. Additionally, if the second indication message is a group common DCI, the gNB can configure relevant configuration information for group common DCI detection, such as search space configuration information and CORSET configuration information.
[0166] The second indication information (group common DCI) can indicate the configuration parameters of available (or effective) random access resources within a certain period (e.g., a first time range). The UE determines the available (or effective) random access resources within this period based on the DCI, such as the distribution of available (or effective) ROs. Here, the time granularity of this period (e.g., the first time range) can be in units of radio frames, subframes, time slots, etc.; the period can be fixed, for example, predefined by the protocol, or indicated by the second indication information, and can change as the period in the second indication information is set to different values.
[0167] As shown in Figure 4, if the UE receives DCI 1 during the second indication message transmission opportunity and determines that the random access resource configuration 1 is available (or effective), the UE can send a random access preamble on the available (or effective) random access resource. The gNB needs to detect the random access preamble on the available (or effective) random access resource. Subsequently, if the UE does not detect DCI 2 during the next second indication message transmission opportunity, the UE can assume that the random access resource configuration 1 configured in DCI 1 remains available (or effective). When the gNB wants to adjust the available (or effective) random access resource configuration (RO distribution), it can carry the new random access resource configuration parameters by retransmitting the second indication message (DCI 2). The configuration information for the first time range 1 and the first time range 2 in Figure 4 can be carried in the second indication message, or it can be indicated by the gNB through other messages.
[0168] In this embodiment, the terminal can directly determine the first random access resource based on the second indication information sent by the network-side device, and thus can send a preamble on the first random access resource. The network-side device receives the preamble on the first random access resource based on the same understanding, which can reduce energy consumption.
[0169] Example 4: Types of random access resources.
[0170] Random access resources include at least two types:
[0171] Random access resource type 1: normal random access resource (general random access resource), that is, the random access resource configured by the gNB through system messages. Once the normal random access resource is configured in the system message sent by the gNB, the terminal considers the random access resource to be available (or effective). The UE can use the normal random access resource for random access. The gNB also needs to detect the random access preamble on the RO corresponding to the normal random access resource.
[0172] Random access resource type 2: on-demand random access resource (or candidate random access resource):
[0173] After configuring on-demand random access resources in the gNB, the on-demand random access resources are unavailable (or ineffective) by default. The terminal can determine the available (or effective) on-demand random access resources by using the methods in Example 1 or Example 2 above.
[0174] The gNB can also configure available (or effective) on-demand random access resources through the second instruction information in Example 3 above.
[0175] From a network energy-saving perspective, the gNB can configure time-sparse normal random access resources and time-dense on-demand random access resources. Available (or effective) on-demand random access resources are determined by the terminal sending the first UL WUS or by the gNB sending an indication message. In low-load scenarios with low UL data, there are fewer available (or effective) on-demand random access resources, and the gNB does not need to frequently detect ROs, thus saving energy. In this case, for UEs with high latency requirements, the first UL WUS can be used to wake up the on-demand random access resources, thus ensuring random access latency.
[0176] In embodiments of this disclosure, the terminal determines a first random access resource based on a first uplink signal and / or indication information sent by the network-side device. The terminal can send a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource, thereby ensuring accurate reception of the preamble sent by the terminal. This method can more flexibly determine available random access resources and avoid the power consumption waste caused by the gNB frequently detecting random access resources.
[0177] As shown in Figure 5, this embodiment of the present disclosure also provides a method for determining random access resources, applied to a network-side device, including:
[0178] Step 501: Determine the first random access resource based on the first information, wherein the first random access resource is used to receive the preamble;
[0179] The first information includes at least one of the following:
[0180] The terminal sends a first uplink signal, which is used to wake up or request the first random access resource;
[0181] The network-side device sends an indication message, and the first random access resource determined based on the indication message is a random access resource within a first time range.
[0182] In this embodiment, the network-side device can determine a first random access resource based on a first uplink signal and / or indication information sent by the network-side device. This first random access resource is the resource used by the terminal to send a preamble, and the network-side device can receive the preamble on this first random access resource. This preamble can be a random access preamble, also referred to as the first uplink signal in the random access process, such as Msg 1 in four-step random access or Msg A in two-step random access. The first random access resource can be at least a portion of the random access resources configured by the network-side device, and this first random access resource can be considered a usable random access resource. In some embodiments, after determining the first random access resource, the terminal can use it to send the preamble. The network-side device and the terminal have the same understanding of the first random access resource, and the network-side device can receive the preamble sent by the terminal on this first random access resource.
[0183] The first uplink signal can be sent by the terminal that determines the first random access resource. For example, terminal A sends the first uplink signal and determines the first random access resource based on the first uplink signal. Terminal A can use the first uplink signal to wake up or request the first random access resource to send a preamble. Alternatively, the first uplink signal can also be sent by another terminal, which is a terminal other than the terminal that determines the first random access resource. For example, terminal B sends the first uplink signal, which is used to wake up or request the first random access resource. Terminal A determines the first random access resource based on the first uplink signal sent by terminal B. For example, if terminal A receives feedback information from the network-side device regarding the first uplink signal sent by terminal B, and the feedback information includes confirmation information, terminal A can use the first uplink signal to wake up or request the first random access resource to send a preamble.
[0184] In some embodiments, the first uplink signal may be UL WUS or other uplink signals, such as uplink signals capable of triggering SIB or SIB1. The terminal sends the first uplink signal to the network-side device. The first random access resource requested or activated by this first uplink signal may be at least a portion of the random access resources configured by the network-side device. For example, the terminal receives random access resource configuration information sent by the network-side device, and sends the first uplink signal to the network-side device to request the first random access resource, which is a portion of the random access resources configured in the configuration information. Based on the same understanding, the terminal and the network-side device determine the first random access resource according to the first uplink signal. The terminal can then send a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource, avoiding the need for the network-side device to detect preambles on all configured random access resources, thus saving energy.
[0185] The terminal and network-side equipment can also determine the first random access resource based on the indication information sent by the network-side equipment. This can be understood as the network-side equipment indicating available random access resources through the indication information. The indication method can be direct, such as the indication information directly indicating available random access resources, or indirect, such as indicating unavailable random access resources, from which the terminal further determines available random access resources. The first random access resource determined based on this indication information can be at least a portion of the random access resources configured by the network-side equipment. If the first random access resource determined based on this indication information is a random access resource within a first time range, the terminal can send a preamble on the random access resources within that first time range. Correspondingly, the network-side equipment detects the preamble on the random access resources within that first time range. This avoids the need for the network-side equipment to detect preambles on all configured random access resources, saving energy.
[0186] In some embodiments, the terminal and the network-side device may simultaneously determine the first random access resource based on the first uplink signal and the indication information sent by the network-side device. For example, the terminal sends the first uplink signal to wake up or request the first random access resource; the network-side device sends indication information to the terminal based on the first uplink signal, and the terminal and the network-side device further determine the first random access resource based on the indication information.
[0187] In some embodiments, the random access resource in this disclosure may be a RO. The available random access resource in this disclosure may also be understood as a valid (or effective) random access resource; the unavailable random access resource may also be understood as an invalid (or failed) random access resource.
[0188] In embodiments of this disclosure, the network-side device determines a first random access resource based on a first uplink signal sent by the terminal and / or an indication information sent by the network-side device. The terminal can send a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource, thereby ensuring accurate reception of the preamble sent by the terminal. This method can more flexibly determine available random access resources and avoid the power consumption waste caused by the network-side device frequently detecting random access resources.
[0189] As an optional embodiment, determining the first random access resource based on the first information includes:
[0190] The random access resource associated with the first uplink signal is determined to be the first random access resource;
[0191] or,
[0192] Feedback information of the first uplink signal is sent to the terminal. If the feedback information includes confirmation information, the random access resource associated with the first uplink signal is determined to be the first random access resource.
[0193] In this embodiment, if the terminal transmits a first uplink signal during a first uplink signal transmission opportunity, the network-side device can consider the random access resource associated with the first uplink signal to be a first random access resource, or it can be understood as considering the random access resource associated with the first uplink signal to be an available random access resource. The terminal can transmit a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource.
[0194] Alternatively, after the terminal sends the first uplink signal on the first uplink signal transmission opportunity, the network-side device determines whether to send feedback information for the first uplink signal. If feedback information is sent and includes acknowledgment information, then the random access resource associated with the first uplink signal is considered to be the first random access resource. This can also be understood as determining, based on the feedback information, that the random access resource associated with the first uplink signal is an available random access resource. The terminal can send a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource.
[0195] As an optional embodiment, the method further includes:
[0196] If the first uplink signal is not received from the terminal, it is determined that the random access resource associated with the first uplink signal is an unavailable random access resource.
[0197] In this embodiment, before receiving the first uplink signal sent by the terminal, the network-side device considers the random access resource associated with the first uplink signal to be unavailable, which can also be understood as not detecting the random access resource associated with the first uplink signal by default.
[0198] Alternatively, if the network-side device receives the first uplink signal sent by the terminal but does not send an acknowledgment message to the terminal, it considers the random access resource associated with the first uplink signal to be unavailable and does not detect the random access resource associated with the first uplink signal.
[0199] As an optional embodiment, the random access resource associated with the first uplink signal is a random access resource within a first time range.
[0200] In this embodiment, the first uplink signal is associated with random access resources, and the random access resources associated with the first uplink signal are random access resources within a first time range. These random access resources within the first time range can be at least a portion of the random access resources configured by the network-side device. The terminal can then send a preamble on these random access resources within the first time range, and correspondingly, the network-side device detects the preamble on these random access resources within the first time range.
[0201] As an optional embodiment, the first uplink signal is associated with random access resources within a first time range, and the association includes at least one of the following:
[0202] (1) The generation sequence of the first uplink signal is related to the random access resources within the first time range; for example, different sequences can correspond to different random access resources within the first time range.
[0203] (2) The resource location of the first uplink signal is associated with the random access resources within the first time range; for example, the resource location of the first uplink signal and the location of the random access resources within the first time range satisfy a preset offset or an offset configured by the network-side device; for another example, different resource locations of the first uplink signal can correspond to different random access resources within the first time range.
[0204] (3) The indication field carried by the first uplink signal is associated with the random access resources within the first time range. For example, the random access resources within the first time range can be indicated within the indication field carried by the first uplink signal, and different indication fields carried by the first uplink signal can indicate different random access resources within the first time range.
[0205] In this embodiment, the first uplink signal is associated with random access resources within a first time range. The terminal and the network-side device have a consistent understanding of this association. After the terminal sends the first uplink signal, the network-side device can determine the random access resources associated with the first uplink signal based on this association, thereby determining that the random access resources associated with the first uplink signal are available.
[0206] As an optional embodiment, the indication information includes at least one of the following:
[0207] (1) First indication information, used to indicate that random access resources are available and / or unavailable within the first time range;
[0208] In this scenario, the network-side device indicates the availability and / or unavailability of random access resources within a first time range via the first indication information. For example, when a terminal receives configuration information of random access resources and the first indication information sent by the network-side device, the terminal and the network-side device can determine candidate random access resources based on the configuration information and determine the availability and / or unavailability of random access resources within a first time range among the candidate random access resources based on the first indication information.
[0209] For example, if the first indication information indicates that random access resources within a first time range are available, the terminal and network-side devices can determine that the random access resources within the first time range are the first random access resources based on the first indication information, and thus can send a preamble.
[0210] For example, before sending the first indication information, the network-side device assumes that random access resources within a first time range are available. When the first indication information is sent and indicates that random access resources within the first time range are unavailable, it determines that the random access resources within that first time range are unavailable. Alternatively, if the first indication information indicates that random access resources within the first time range are unavailable, the terminal and the network-side device can further determine available random access resources based on the unavailable random access resources. For example, they can determine that among all candidate random access resources configured by the network-side device, resources other than the unavailable random access resources are available.
[0211] (2) Second indication information, used to indicate the configuration information of the first random access resource.
[0212] In this embodiment, the network-side device can directly indicate the configuration information of the first random access resource through the second indication information. The configuration information may be, for example, the time-domain configuration information and / or frequency-domain configuration information of the first random access resource. In this way, the terminal and the network-side device can directly determine the first random access resource and can send a preamble in the first random access resource.
[0213] In some embodiments, the method further includes: determining that random access resources within the first time range are unavailable random access resources without sending the first indication information.
[0214] In this embodiment, before sending the first indication information, the network-side device assumes that the random access resources within the first time range are unavailable by default, for example, the ROs within the first time range are considered invalid ROs by default. Only when the network-side device sends the first indication information, and the first indication information indicates that the ROs within the first time range are available (or valid), are the ROs within the first time range considered valid ROs, and the preamble is received on the ROs within the first time range, thereby saving energy consumption.
[0215] In some embodiments, the indication information includes information for determining the first time range. For example, when indicating the availability and / or unavailability of random access resources within a first time range via first indication information, the first indication information may also include information for determining the first time range. As another example, when indicating the configuration information of a first random access resource via second indication information, information about the first time range corresponding to that first random access resource may also be indicated. The information for determining the first time range may include one or more of the following: the random access resources included in the first time range, the number of PRACH association periods corresponding to the first time range, the length of the first time range, the period of the first time range, etc.
[0216] In some embodiments, the indication information is group common downlink control information (DCI). The network-side device can use this DCI to indicate the availability and / or unavailability of random access resources within a first time range; and / or use this DCI to indicate the configuration information of the first random access resource.
[0217] As an optional embodiment, the random access resources within the first time range include random access resources corresponding to M random access resource units, where M is a positive integer.
[0218] In this embodiment, the random access resources within the first time range can be divided into one or more random access resource units (ROs), and each RO may include one or more ROs. In some embodiments, the candidate random access resources configured by the network-side device can also be divided into one or more candidate random access resource units, and the M random access resource units included in the first time range are at least a portion of the candidate random access resource units configured by the network-side device. Thus, the granularity of the first random access resource that the terminal wakes up or requests through the first uplink signal, the random access resource indicated by the network-side device through indication information, and the first random access resource determined by the terminal according to the indication information can all be ROs.
[0219] As an optional embodiment, the random access resource corresponding to the random access resource unit is determined according to the second information, which includes at least one of the following:
[0220] 1) The number of physical random access channel (PRACH) association periods corresponding to one random access resource element;
[0221] In this embodiment, the random access resources (e.g., ROs) contained in a random access resource unit can be determined according to the PRACH association period. For example, a random access unit corresponds to X (X is greater than 0) PRACH association periods. The PRACH association period is the period during which the SSBs of different beam directions and all ROs complete one round of mapping. Based on the number of PRACH association periods corresponding to a random access unit, the number of random access resources (e.g., ROs) contained in a random access unit can be determined.
[0222] 2) Number of beams in a Synchronization Signal Block (SSB); The number of random access resources contained in a random access resource unit (RO) can also be determined based on the number of beams in the SSBs contained in the RO. For example, if an RO corresponds to x SSBs, then the number of ROs contained in a random access resource unit can be determined.
[0223] 3) The number of SSB beams corresponding to one random access opportunity (RO); the number of random access resources (such as RO) contained in a random access resource element can also be determined based on the number of SSB beams corresponding to one RO. For example, one RO corresponds to x SSBs, and the number of ROs contained in a random access resource element can be determined based on the number of SSBs.
[0224] 4) Configuration information related to Random Access Resource Units (ROs) sent by the network-side device, including the length and / or period of the RO. The network-side device can configure the random access resources corresponding to a RO using this configuration information. For example, configuring the length of a RO determines the number of ROs corresponding to that length; similarly, configuring the period of a RO allows the determination of the number of ROs contained within that period. This configuration information can be configuration information used to configure random access resources or independent configuration information.
[0225] As an optional embodiment, the first indication information indicates the availability and / or unavailability of random access resources within the first time range, including one of the following:
[0226] (a) The first indication information includes a first field, which includes 1 bit of information, and the 1 bit of information is used to indicate whether the random access resources corresponding to the M random access resource units are available or unavailable;
[0227] The first indication information may be a Group Common Downlink Control Information (DCI), and the first field of the DCI may be 1 bit, which indicates whether the random access resources corresponding to the M random access resource elements are available (or active) or unavailable (or inactive). That is, different random access resource elements among the M random access resource elements are not indicated independently.
[0228] (b) The first indication information includes a first field, which includes M bits of information, each bit of the M bits of information being used to indicate whether the random access resource corresponding to one of the M random access resource units is available or unavailable;
[0229] The first indication information may be a Group Common Downlink Control Information (DCI). The first field of the DCI may be of length M bits, such as a bitmap of length M. The M bits in the bitmap indicate whether the random access resource corresponding to each of the M random access resource units is available (or active) or unavailable (or inactive). That is, different random access resource units among the M random access resource units can be indicated independently.
[0230] (c) The first indication information includes a first field, which includes Y bit information. Each bit in the Y bit information is used to indicate whether the random access resource corresponding to a random access resource unit group among M random access resource units is available or unavailable. Y is a positive integer, and a random access resource unit group includes at least one random access resource unit.
[0231] The first indication information may be Group Common Downlink Control Information (DCI). The first field of this DCI may be Y bits or a bitmap of length Y, where each bit corresponds to a group of Random Access Resource Units (RLUs), and each bit indicates whether the random access resources in a RLU group are available (or active) or unavailable (or ineffective). Alternatively, the Y bits in the bitmap may respectively indicate the availability (or active) or unavailable (or ineffective) of each of the Y RLU groups. Each RLU group contains one or more RLUs, and each RLU contains one or more random access resources.
[0232] In embodiments of this disclosure, the random access resources corresponding to the first time range are determined based on third information, which includes at least one of the following:
[0233] 1) The number of PRACH association cycles corresponding to the first time range; In this embodiment, the first time range may correspond to y PRACH association cycles, which is the cycle in which SSB and all RO complete one round of mapping. When the length of the PRACH association cycle is known, the length of the first time range can be determined.
[0234] 2) Number of SSB beams; The first time range can be determined based on the number of SSB beams contained in the first time range. For example, the number of ROs contained in the first time range can be determined based on the mapping relationship between SSB and RO.
[0235] 3) The number of SSB beams corresponding to one RO; for example, the number of ROs in the first time range can be determined based on the number of SSB beams contained in the first time range and the number of SSB beams corresponding to one RO.
[0236] 4) Configuration information for a first time range sent by the network-side device, wherein the configuration information includes: the length and / or period of the first time range. For example, if the network-side device configures the length of the first time range, the number of ROs corresponding to that length can be determined; or, for example, if the network-side device configures the period of the first time range (e.g., 160ms), the number of ROs included in the first time range can be determined based on the number of ROs within that period. The configuration information can be configuration information for configuring random access resources or independent configuration information.
[0237] As an optional embodiment, the method further includes:
[0238] If the indication information is sent at the first location but not at the second location, the first random access resource determined based on the indication information sent at the first location remains available.
[0239] The second position is the location where the indication information is sent after the first position.
[0240] In this embodiment, when the network-side device sends indication information (which may be either first or second indication information) at the first location, and does not send new indication information at the subsequent second location, the indication information previously sent at the first location can be considered to remain valid, meaning the first random access resource determined based on the indication information sent at the first location remains available. If the network-side device sends new indication information at the second location, the first random access resource is re-determined based on the new indication information.
[0241] As an optional embodiment, the types of random access resources include: general random access resources and on-demand random access resources;
[0242] In the case where the general random access resource is configured, it is determined that the general random access resource is an available random access resource.
[0243] When the on-demand random access resources are configured, the first random access resource is determined from the on-demand random access resources based on the first information.
[0244] In this embodiment, the type of random access resource may include: normal random access resource and on-demand random access resource. The terminal and network-side device consider normal random access resource to be effective (or available) immediately after configuration. For on-demand random access resource, the terminal and network-side device use the method described above for determining the first random access resource based on the first information to determine its availability (or effectiveness). This can also be understood as the method for determining the first random access resource based on the first information in this embodiment being for on-demand random access resource.
[0245] From the perspective of network energy saving, network-side equipment can configure time-sparse normal random access resources and time-dense on-demand random access resources. Available on-demand random access resources are determined by the terminal sending the first uplink signal or by the network-side equipment sending indication information. In low-load scenarios with low UL data, there are fewer available on-demand random access resources, and the network-side equipment does not need to frequently detect RO, thus saving energy. At this time, for UEs with high latency requirements, the first uplink signal can be used to wake up the on-demand random access resources, thus ensuring random access latency.
[0246] In embodiments of this disclosure, the network-side device determines a first random access resource based on a first uplink signal sent by the terminal and / or an indication information sent by the network-side device. The terminal can send a preamble on the first random access resource, and the network-side device can receive the preamble on the first random access resource, thereby ensuring accurate reception of the preamble sent by the terminal. This method can more flexibly determine available random access resources and avoid the power consumption waste caused by the network-side device frequently detecting random access resources.
[0247] Based on the same technical concept, this disclosure also provides a device for determining random access resources. This device can implement the terminal-side functions described in the foregoing embodiments.
